Determining the influence of hemp seed protein on the quality indicators of cheese product and the content of nutrients in it

The growing tendency to produce cheese from animal and plant ingredients has led to the diversification of cheese-making technologies and the search for new cheese suitable raw materials. The research object is the technology of cheeses made from combined raw materials: cow's milk and hemp seed proteins. Subjects of research: organoleptic and physical-chemical indicators of cheese product samples; amino acid composition of cheese product samples. The inclusion of vegetable raw materials in the cheese technology affects the technical properties of milk-plant mixtures, in particular, their syrupy properties, and the quality of the finished cheese product. Samples of cheeses were produced according to the traditional technology of Cachotta type cheese. The conducted research established that the proteins of hemp seeds affect the sensory characteristics of cheese. Increasing the content of hemp protein in recipes leads to the appearance of a brown-green color of the cheese product. The taste and smell acquire a characteristic shade of hemp. When vegetable proteins are used in the recipe of cheese, the yield of the finished product increases by 0.3...23.5 %. In experimental samples, the content of fat (by 0.3...2.2 %) and protein (by 1.75...10.4 %) increases. Hemp seed protein balances the amino acid profile in finished cheese. The total content of amino acids in cheese samples was as follows: H10 – 8.25, H15 – 8.35, H20 – 8.44, and H25 – 8.53 mg/g of protein, which is relatively higher than in the control sample H0 – 8.08 mg/g of protein. Taking into account the results of the sensory analysis of the expert commission and the balanced biological profile, the recommended concentration of hemp seed protein in the milk-vegetable mixture is 20 %, which guarantees the acceptable quality of the product. The obtained results are of practical importance, since it can be taken into account that the combination of raw materials of plant and animal origin expands the assortment, increases the raw material base and the output of cheese, and therefore, the profitability of production

Advancing 6-bromo-7-[11C]methylpurine to clinical use: improved regioselective radiosynthesis, non-clinical toxicity data and human dosimetry estimates

Background6-Bromo-7-[11C]methylpurine ([11C]BMP) is a radiotracer for positron emission tomography (PET) to measure multidrug resistance-associated protein 1 (MRP1) transport activity in different tissues. Previously reported radiosyntheses of [11C]BMP afforded a mixture of 7- and 9-[11C]methyl regioisomers. To prepare for clinical use, we here report an improved regioselective radiosynthesis of [11C]BMP, the results of a non-clinical toxicity study as well as human dosimetry estimates based on mouse PET data.Results[11C]BMP was synthesised by regioselective N7-methylation of 6-bromo-7H-purine (prepared under good manufacturing practice) with [11C]methyl triflate in presence of 2,2,6,6-tetramethylpiperidine magnesium chloride in a TRACERlab™ FX2 C synthesis module. [11C]BMP was obtained within a total synthesis time of approximately 43 min in a decay-corrected radiochemical yield of 20.5 ± 5.2%, based on starting [11C]methyl iodide, with a radiochemical purity > 99% and a molar activity at end of synthesis of 197 ± 130 GBq/μmol (n = 28). An extended single-dose toxicity study conducted in male and female Wistar rats under good laboratory practice after single intravenous (i.v.) administration of unlabelled BMP (2 mg/kg body weight) revealed no test item related adverse effects. Human dosimetry estimates, based on dynamic whole-body PET data in female C57BL/6J mice, suggested that an i.v. injected activity amount of 400 MBq of [11C]BMP will deliver an effective dose in the typical range of 11C-labelled radiotracers.Conclusions[11C]BMP can be produced in sufficient amounts and acceptable quality for clinical use. Data from the non-clinical safety evaluation showed no adverse effects and suggested that the administration of [11C]BMP will be safe and well tolerated in humans.

Spiced-marinating injection brine effect on the entire pork quality

Searching for new alternatives to commercialize pork from entire male pigs that could be affected by a boar taint sensory defect would be adequate. In this study, two different marinade mixtures (additives, salt, white wine plus different spices for mixture 1 and 2) were injected into pork loin pieces from castrated (C1 and C2) and entire male pigs (E1 and E2) with a high boar taint level (5.51 µg.g−1 AND and 0.73 µg.g−1 SKA) to evaluate their effect on the physicochemical and sensory quality of pork, and to assess their boar taint masking properties. To achieve this, physicochemical and sensory analyses with trained panellists were carried out. Marinated meat showed some differences in colour and a reduction in cooking losses. Mixture 2 achieved the best boar taint masking effect, due to spices content mainly nutmeg and ginger, and other ingredients such as white wine. In conclusion, marinating pork from entire male pigs can contribute to achieving an acceptable quality standard.

Nutrient Use Efficiency and Grain Quality of Malt Barley (Hordeum vulgare L.) Varieties in Response to Nitrogen Fertilizer in, Southeastern Ethiopia

The expansion of brewing industries in Ethiopia has been inducing a growing demand for the supply of malt with optimum kernel protein content. However, the supply has been constrained by the unavailability of sufficient volumes of acceptable quality of malting barley grain to meet the ever-increasing demand. In this regard, field experiments were conducted in the southeastern Ethiopian highlands to evaluate the combined effects of six fertilizer levels (0, 11.5, 23, 34.5, 46, and 57.5) N kg ha<sup>-1 </sup>and three malt barley varieties (Fanaka, Ibon and Holker) on the yield, quality and nutrient use efficiency of malting barley. The experiment was laid out in a randomized complete block design with three replications. Application of 11.5, 23, 34.5, 46 and 57.5 N kg ha<sup>-1</sup> increased the grain yields by 1010.3, 1065.9, 1288.1, 1421.3, and 1777.6 kg ha<sup>-1</sup> and economic benefits by 31 ETB, 30.4 ETB, 32.9 ETB, 33.16 ETB and 33.38 ETB respectively, for each increment of on N fertilizer, when compared to the control treatment. The production of malting barley with improved yield, optimum kernel protein concentrations and enhanced economic benefit was attained through 57.5 and 46 N kg ha<sup>-1</sup> as first and second option respectively in the study area. Thus, to improve the likelihood of acceptance of malting barley by malting industries, growers are recommended to select low-protein containing varieties and decide application of N fertilization based on soil test results.

Missing information on the link between cell death mechanisms and good eating quality in cultured myofoods

BackgroundCommercial interest in the production of cultured myoproducts (cultured “meat”) has grown in a broad range of companies. As has been shown with plant-based meat alternatives, consumer acceptance of such products will depend on their eating quality, as well as cost, ethical and sustainability issues. Scope and approachPrincipal factors in the sensory quality of conventionally-produced meat (texture, colour, flavour, juiciness) are very much affected by post-mortem metabolism in muscle tissue. However, there is a lack of information on how cell death and subsequent metabolism may affect the eating quality of cultured myoproducts. Key finding/hypothesisThe main mechanisms of cell death in cell culture are apoptosis, necrosis and autophagy. Knowledge of the conditions and pathways inducing these and other mechanisms of cell death provides a conceptual framework of how cell harvesting conditions could be used to manipulate post-mortem metabolism in cultured myoproducts. Because the structure, composition and protein isoforms present will differ in conventional meat versus cultured products, a key question will be whether the well-understood post-mortem metabolic processes in the conversion of muscle to meat are desirable, or should be altered, to achieve acceptable sensory qualities of cultured myoproducts. ConclusionPublished information on post-mortem metabolism in cultured muscle cells is entirely lacking. Although post-mortem metabolism will differ with specific cell line and bioreactor conditions, general studies in the area should provide important tools in manipulating the end-product quality of cultured myofoods.

Mechanical Complications of Proximal Femur Fractures Treated with Intramedullary Nailing: A Retrospective Study.

Background and Objectives: This retrospective cohort study analyzes mechanical complications in hip fracture surgery using the Trochanteric Fixation Nail-Advanced (TFNA) implant. It investigates the correlation of these complications with demographic, intraoperative, and radiological factors, aiming to identify associated risk factors and suggest improvements in clinical surveillance and treatment strategies. Materials and Methods: We enrolled 253 patients diagnosed with pertrochanteric hip fractures treated between 2017 and 2021, with 126 meeting the criteria for a minimum 6-month follow-up. Data on demographics, American Anesthesia Association Classification (ASA), comorbidities, AO/OTA [AO (Arbeitsgemeinschaft für Osteosynthesefragen)/OTA (Orthopedic Trauma Association)] fracture classification, procedural details, and time to failure were collected. Radiographs were evaluated for reduction quality, the tip-apex distance (TAD), progressive varus deviation, and identification of mechanical complications. Statistical analysis was performed using SPSS software. Results: The predominant AO/OTA fracture classification was 31A2 in 67 cases (52.7%). Reduction quality was deemed good or acceptable in 123 cases (97.6%). The mean time to failure was 4.5 months (range: 2.2-6). The average TAD was 18 mm (range: 1.2-36), with a mean progressive varus deviation of 2.44° (range: 1.30-4.14). A good or acceptable reduction quality was observed in 97.6% of cases. Mechanical complications occurred in 21.4% of patients, with significant associations found with the lateral cortex fracture, use of a TFNA implant with a 130° angle, open reduction, and absence of prior osteoporosis treatment. Conclusions: The study provides insights into mechanical complications in proximal femur fractures treated with the TFNA nail, emphasizing the need for enhanced clinical and radiographic surveillance, especially in patients without osteoporosis treatment. Our findings support the necessity for further clinical studies comparing these outcomes with other implant designs and underscore the importance of personalized treatment strategies to reduce complication rates.

Examining contributing factors for the implementation of inclusion students with disabilities from the perspective of university academics in Saudi Arabia

Inclusive education focuses on implementing education for individuals who do not follow typical learning trajectory and require special educational needs (SEN). Educational systems in many countries around the world, including Saudi Arabia, tend to implement and practise inclusive education in order to fulfill relevant international conventions and achieve educational standards of acceptable quality in educating children and young people with medical and neurodevelopmental conditions. This study seeks to reveal some of the factors that may help to overcome the obstacles faced in the implementation of inclusive education from the point of view of academics of special education in Saudi universities. To achieve this goal, the study used semi-structured interviews as its primary tool for data collection. Sixteen male and female faculty members specialized in special education in several Saudi public universities were interviewed. The data were analysed thematically. Two master themes were derived from the thematic analyses, 1) theoretical factors and 2) applied factors. Both master themes had several sub-themes. A number of factors were identified as helping to implement inclusive education thereby changing the behaviours and attitudes towards including students with disabilities Saudi context. It is suggested here that similar factors might exist in other countries in Middle East and beyond.

Enhancing litchi shelf life with gluten-based nanocomposite films: A comparative study of montmorillonite and starch nanocrystals reinforced with chitosan

This study investigates the efficacy of gluten films incorporated with montmorillonite (MMT) and starch nanocrystals (SNCs), further enriched with chitosan, in preserving the quality of litchis over a 20-day storage period at 4 °C. The addition of MMT/SNCs along with chitosan boosts the tensile strength (52.44 to 57.00 MPa) and surface uniformity of the films while also decreasing water vapour transmission rates (0.77 to 0.68 × 10−3 g/m2/h). Notably, litchis wrapped in these nanocomposite films demonstrate superior shelf stability compared to untreated litchis, which undergo considerable deterioration. Among the film variants, SNCs/chitosan films (GSL2) outperform MMT/chitosan (GML2) due to their superior barrier properties. By the 20th day of storage, litchis packaged in GSL2 films display reduced antioxidant enzyme activity (polyphenol oxidase: 3.18 to 8.08 unit/min/g fruit weight; peroxidase: 0.94 to 5.29 unit/min/g fruit weight) and higher retention of bioactive compounds, including anthocyanin (9.15 to 9.90 mg/100 g), phenolics (347.7 to 362.07 mg/100 g), and ascorbic acid (28.21 to 29.09 mg/100 g) in litchi pericarps during last intervals. Similarly, less alteration was observed in the firmness (8.47 % and 7.36 %) and weight loss (24.04 % and 19.86 %) of the litchis packaged in GML2 and GSL2, respectively as compared to unpackaged litchis. Notably, litchi pericarp exhibits negligible functional group changes when packed in GML2 and GSL2 films until the 15th day of storage. In summary, GML2 and GSL2 films effectively maintain acceptable litchi quality for three weeks.

Surgical management of renal cell carcinoma with subhepatic inferior vena cava tumor thrombus: a case report and review of the literature

BackgroundRenal cell carcinomas are the most common form of kidney cancer in adults. In addition to metastasizing in lungs, soft tissues, bones, and the liver, it also spreads locally. In 2–10% of patients, it causes a thrombus in the renal or inferior vena cava vein; in 1% of patients thrombus reaches the right atrium. Surgery is the only curative option, particularly for locally advanced disease. Despite the advancements in laparoscopic, robotic and endovascular techniques, for this group of patients, open surgery continues to be among the best options.Case reportHere we present a case of successful tumor thrombectomy from the infrahepatic inferior vena cava combined with renal vein amputation and nephrectomy. Our patient, a 58 year old Albanian woman presented to the doctors office with flank pain, weight loss, fever, high blood pressure, night sweats, and malaise. After a comprehensive assessment, which included urine analysis, complete blood count, electrolytes, renal and hepatic function tests, as well as ultrasonography and computed tomography, she was diagnosed with left kidney renal cell carcinoma involving the left renal vein and subhepatic inferior vena cava. After obtaining informed consent from the patient we scheduled her for surgery, which went well and without complications. She was discharged one week after to continue treatment with radiotherapy, chemotherapy, and immunotherapy.ConclusionOpen surgery is a safe and efficient way to treat renal cell carcinoma involving the renal vein and inferior vena cava. It is superior to other therapeutic modalities. When properly done it provides acceptable long time survival and good quality of life to patients.

Improvement of Raw and Pasteurized Milk Quality through the Use of Lactoperoxidase Systems (LPSs) along the Dairy Value Chain, under Real Conditions in Ethiopia.

Lactoperoxidase systems (LPSs) can enhance the microbiological quality of raw milk when there is lack of cooling facilities. In this study, a total of 250 milk samples were collected from farmers, collectors, and factories. Experimental samples were both LPS-activated morning and overnight milk. The samples were tested with several chemical and microbiological tests, such as total bacterial count (TBC), total coliform count (TCC), and Escherichia coli count (EC). Results indicated that all LPS-activated milk samples had a higher quality than all the control samples. For instance, both the morning and overnight farm milk samples had mean TBCs of 5.79 log and 6.55 log cfu/mL, which is significantly (p < 0.05) lower than the control samples' mean TBC of 6.73 log and 7.31 log cfu/mL, respectively. When this was compared with the Ethiopian Standard, 51.4% of morning and 39.5% of overnight farm milk with LPS activation met the acceptable quality, while only 28% of morning and 15.7% of overnight control milk met the standard. Moreover, LPS activation has also significantly improved the shelf life of collectors' raw milk and pasteurized milk at the factories. Therefore, a better hygienic practice with LPS application can be practiced in conditions that lack cooling infrastructure and electricity.

The present investigation entitled “Preparation of cow milk shrikhand blended with calcutta betel vine (Piper betel) leaves extract” was conducted at Section of Animal Husbandry and Dairy Science, Nagpur. An effort was made to find out the physicochemical properties and calculate the cost structure. Some of the findings emerged from the present investigation are summarized as follows. Concerning the chemical composition of Calcutta betel vine leaves extract added in shrikhand, it was observed that the fat, protein and titratable acidity content were slightly decreased with addition of different levels of Calcutta betel vine leaves extract. The moisture, ash and pH of shrikhand was significantly increased. The total solids and solids not fat content of shrikhand was decreased with increase the level of Calcutta betel vine leaves extract. As regards to the cost of production per kg shrikhand was lowest in T1 (Rs. 238.23 kg-1) and highest in T5 (Rs.294.81 kg-1). Which indicates that, increase in the level of Calcutta betel vine leaves extract showed increase in cost of production for preparation of shrikhand. The present study concluded that acceptable quality shrikhand can be prepared by adding 6 % Calcutta betel vine leaves extract.

Antimicrobial resistance of Enterobacteriaceae and Staphylococcus spp. isolated from raw cow's milk from healthy, clinical and subclinical mastitis udders

Mastitis is the most common disease of dairy cattle and can be manifested in clinical and subclinical forms. The overuse of antimicrobials in the treatment and prevention of mastitis favours antimicrobial resistance and milk can be a potential route of dissemination. This study aimed to evaluate the biological quality of bulk tank milk (BTM) and the microbiological quality and signs of mastitis of freshly milked raw milk. In addition, to evaluate antimicrobial resistance in Enterobacteriaceae and Staphylococcus spp. isolated from freshly milked raw milk. None of the farms were within the official Brazilian biological quality limits for BTM. Freshly milked raw milk with signs of clinical (CMM), subclinical (SCMM) and no signs (MFM) of mastitis were detected in 6.67%, 27.62% and 65.71% samples, respectively. Most samples of freshly milked raw milk showed acceptable microbiological quality, when evaluating the indicators total coliforms (78.10%), Escherichia coli (88.57%) and Staphylococcus aureus (100%). Klebsiella oxytoca and S. aureus were the most prevalent microorganisms in SCMM and MFM samples. Antimicrobial resistance and multidrug resistance (MDR) were observed in 65.12% and 13.95% of Enterobacteriaceae and 84.31% and 5.88% of Staphylococcus spp., respectively, isolated from both SCMM and MFM samples. Enterobacteriaceae resistant to third-generation cephalosporin (3GCR) (6.98%) and carbapenems (CRE) (6.98%) and methicillin-resistant S. aureus (MRSA) (4.88%) were observed. Antimicrobial-resistant bacteria can spread resistance genes to previously susceptible bacteria. This is a problem that affects animal, human and environmental health and should be evaluated within the one-health concept.

AAPM WGVRTO report 390: A survey of veterinary radiation oncology equipment and infrastructure in 2022.

Since 2010, there has been little published data on the state of equipment and infrastructure in veterinary radiation oncology clinical practice. These data are important not only to identify the status and use of technology within the veterinary radiation oncology community but also to help identify the extent of medical physics support. The purpose of our study is to report findings from a survey of veterinary radiation oncologists in the USA, Canada, and select centers outside of North America in 2022. A 40-question survey covering topics such as type of radiotherapy equipment, techniques offered, treatment planning systems and dose calculation algorithms, special techniques, board-certified radiation oncologists and residents, and extent of medical physics support was distributed through an online survey tool. Results from 40 veterinary radiation oncology institutions, with equipment explicitly used for veterinary care, suggest that the current state of practice is not dissimilar to what currently exists in human radiation oncology facilities; techniques and technologies commonly employed include flattening filter-free mode megavoltage beams, volumetric arc therapy, daily cone-beam computed tomography, image-guided radiation therapy, and sophisticated dose calculation algorithms. These findings suggest the need for modern radiation oncology acceptance testing, commissioning, and quality assurance programs within the veterinary community. The increase in veterinary radiation oncology residency positions and increasing sophistication of equipment suggests that increased levels of standardized medical physics support would benefit the veterinary radiation oncology community.

The clinical complexity among patients with systemic, chronic diseases

ObjectivesThis study aimed to assess the clinical complexity of patients with chronic systemic diseases (systemic lupus erythematosus [SLE] and ANCA-associated vasculitis [AAV]) using the INTERMED Self-Assessment questionnaire (IMSA) to determine the most important factors responsible for this phenomenon in these patients. MethodsThis was a cross-sectional, observational study. Questionnaires were used to evaluate biopsychosocial complexity (IMSA), quality of life (Short Form Survey [SF-36]), mental state (General Health Questionnaire – 28 [GHQ-28] and Hospital Anxiety and Depression Scale [HADS]), and acceptance of illness (Acceptance of Illness Scale [AIS]). ResultsThe final analysis included 81 patients. There was a moderate correlation between clinical complexity (total IMSA score) and quality of life related to mental health (SF-36) and mental state (GHQ-28) in patients with SLE. However, in patients with AAV, clinical complexity had a strong relationship with physical health-related quality of life and a moderate relationship with mental health-related quality of life. Stepwise regression analysis showed that low mental health-related quality of life is a predictor of higher complexity in SLE. The predictors of high clinical complexity in AAV were low physical and mental health-related quality of life and aggravated depressive symptoms (HADS). Other principal factors of clinical complexity were employment status, place of residence, social functioning, and illness duration. ConclusionThis study confirmed the importance of holistic attitudes and complex healthcare among patients with chronic diseases.

Clinical evaluation of isotropic MAVRIC-SL for symptomatic hip arthroplasties at 3 T MRI

Background3D multi-spectral imaging (MSI) of metal implants necessitates relatively long scan times. ObjectiveWe implemented a fast isotropic 3D MSI technique at 3 T and compared its image quality and clinical utility to non-isotropic MSI in the evaluation of hip implants. MethodsTwo musculoskeletal radiologists scored images from coronal proton density-weighted conventional MAVRIC-SL and an isotropic MAVRIC-SL sequence accelerated with robust-component-analysis on a 3-point scale (3: diagnostic, 2: moderately diagnostic, 1: non-diagnostic) for overall image quality, metal artifact, and visualization around femoral and acetabular components. Grades were compared using a signed Wilcoxon test. Images were evaluated for effusion, synovitis, osteolysis, loosening, pseudotumor, fracture, and gluteal tendon abnormalities. Reformatted axial and sagittal images for both sequences were subsequently generated and compared for image quality with the Wilcoxon test. Whether these reformats increased diagnostic confidence or revealed additional pathology, including findings unrelated to arthroplasty that may contribute to hip pain, was also compared using the McNemar test. Inter-rater agreement was measured by Cohen's kappa. Results39 symptomatic patients with a total of 59 hip prostheses were imaged (mean age, 70 years ±9, 14 males, 25 females). Comparison scores between coronal images showed no significant difference in image quality, metal artifact, or visualization of the femur and acetabulum. Except for loosening, reviewers identified more positive cases of pathology on the original coronally-acquired isotropic sequence. In comparison of reformatted axial and sagittal images, the isotropic sequence scored significantly (p < 0.01) higher for overall image quality (3.0 vs 2.0) and produced significantly (p < 0.01) more cases of increased diagnostic confidence (42.4% vs 7.6%) or additional diagnoses (50.8% vs 22.9%). Inter-rater agreement was substantial (k = 0.798) for image quality. Mean scan times were 4.2 mins (isotropic) and 7.1 mins (non-isotropic). ConclusionCompared to the non-isotropic sequence, isotropic 3D MSI was acquired in less time while maintaining diagnostically acceptable image quality. It identified more pathology, including postoperative complications and potential pain-generating pathology unrelated to arthroplasty. This fast isotropic 3D MSI sequence demonstrates promise for improving diagnostic evaluation of symptomatic hip prostheses at 3 T while simultaneously reducing scan time.

Phytochemical screening and insecticidal activities of some medicinal plants against the maize weevil, Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae)

This study emphasizes the phytochemical study of some locally available botanicals against maize weevils. Nine plant parts were collected from six plant species. The test plant powder (200 g) was suspended sequentially in 600 ml of petroleum ether, chloroform, acetone, methanol, and distilled water for 72 h with frequent agitation. Different concentrations of the crude extracts were applied to maize seeds at rates of 10 ml, 15 ml and 20 ml per 100 g. All treatments with different extracts at different rates of application showed significant differences (p < 0.05) in the cumulative mean percentage mortality of the maize weevil. The seed extract of Maesa lanceolata and Croton macrostachyus and the leaf extract of Clausena anisata showed cumulative percent mortality ranged 95.32–98.02% in 28 days after treatment application. There was no significant difference (p > 0.05) among all treatments for the prevention of F1 progeny emergence. In all extracts, Clausena anisata showed 100% inhibition of F1 progeny emergence. All treatments significantly reduced seed weight loss and damage. The treated maize seeds were germinated with an acceptable germination quality. In conclusion, an increased dosage of the extract resulted in significant mortality in maize weevils. The seed extracts of Maesa lanceolata and Croton macrostachyus and Clausena anisata leaf extract were observed to be the most promising botanical in protecting stored maize against maize weevil.

Osseous choanal atresia in a canine patient

AbstractA 2‐year‐old, male, intact dog presented with a history of stertorous breathing since infancy, unresponsive to antibiotic therapy. On rostral rigid endoscopy, there were no remarkable findings. However, computed tomography revealed bilateral atresia of the nasal choanae, with focal hyperossification and severe narrowing, with accompanying hypoventilation of the nasopharynx. Retrograde flexible nasopharyngoscopy confirmed the severe partial choanal atresia. Surgical intervention was declined by the owner due to reasonably acceptable quality of life; therefore, only environmental modifications and symptomatic care have been implemented so far.

Efficiency and Elegance: Exploring Automated Solutions for Public Lighting

This paper explores the intersection of efficiency and elegance in the realm of automated solutions for public lighting. With the rapid advancement of technology, cities around the world are increasingly turning to automated systems to illuminate their streets, parks, and public spaces. These systems offer not only enhanced efficiency in energy consumption but also the opportunity to elevate the aesthetic appeal of urban environments. Through a comprehensive review of existing literature and case studies, this research examines the benefits and challenges associated with automated public lighting solutions. It delves into the technological innovations driving these systems, including sensor-based controls, adaptive lighting algorithms, and integration with smart city infrastructure. Furthermore, the paper explores the role of automated lighting in promoting sustainability and reducing carbon emissions, as well as its impact on public safety and community well-being. By considering factors such as cost-effectiveness, scalability, and user acceptance, it seeks to provide insights into the practical implementation of automated lighting solutions in diverse urban settings. Ultimately, this study aims to shed light on the potential of automated public lighting to not only enhance efficiency but also contribute to the creation of more elegant and livable cities. It underscores the importance of embracing innovation and leveraging technology to create vibrant and sustainable urban environments for current and future generations. When the lights are on it'll dependably stay on until any labor turns off them. So that the support and the fiscal consumption application is more. It might bear checking the board constantly. The crunches of conventional road lighting frame work not only convey premonitory burden to the near plutocrat related part. Yet in addition it confines the administration and keep of the lighting system which leads to the vexation to the public since several lights are n’t glowing and complaints for them has n’t been made. The advancement of green lighting is introductory. An crop among the most abecedarian mortal advancement records is the enhancement of a drop transportation association. These thorough fares and roads must be immaculately lit up with the target that an acceptable perceivable quality is assured to dwindle the failure rate and expansion of the shot of vehicle.

Seam tracking and gap bridging during robotic laser beam welding via grayscale imaging and wobbling

The use of laser beam welding with robotic manipulators is expanding towards wider industrial applications as the system availability increases with reduced capital costs. Conventionally, laser welding requires high positioning and coupling accuracy. Due to the variability in the part geometry and positioning, as well as the thermal deformation that may occur during the process, joint position and fit-up are not always acceptable nor predictable a-priori if simple fixtures are used. This makes the passage from virtual CAD/CAM environment to real production site not trivial, limiting applications where short part preparations are a need like small-batch productions. Solutions that render the laser welding operations feasible for production series with non-stringent tolerances are required to serve a wider range of industrial applications. Such solutions should be able to track the seam as well as tolerating variable gaps formed between the parts to be joined. In this work, an online correction for robot trajectory based on a greyscale coaxial vision system with external illumination and an adaptive wobbling strategy are proposed as means to increase the overall flexibility of a manufacturing plant. The underlying vision algorithm and control architectures are presented; the robustness of the system to poor illumination conditions and variable reflection conditions is also discussed. The developed solution employed two control loops: the first is able to change the robot pose to follow varying trajectories; the second, able to vary the amplitude of circular wobbling as a function of the gap formed in butt-joint welds. Demonstrator cases on butt-joint welds with AISI 301 stainless steel with increased complexity were used to test the efficacy of the solution. The system was successfully tested on 2 mm thick, planar stainless-steel sheets at a maximum welding speed of 25 mm/s and yielded a maximum positioning and yaw-orientation errors of respectively 0.325 mm and 4.5°. Continuous welds could be achieved with up to 1 mm gaps and variable seam position with the developed control method. The acceptable weld quality could be maintained up to 0.6 mm gap in the employed autogenous welding configuration.

Study on Sensory Evaluation and the Optimum Levels of Calcutta Betel Vine (Piper betel) Leaves Extract in the Preparation of Shrikhand

The present investigation was conducted at Section of Animal Husbandry and Dairy Science, College of Agriculture, Nagpur (Dr. PDKV, Akola) during 2022-2023. An effort was made to determine the optimum level of Calcutta betel vine leaves extract in the preparation of shrikhand, with an objective to evaluate the product by sensory quality along with its cost structure and physio-chemical properties. As per current market scenario, the limited variety of shrikhand is available in the stores but this study might help in addition to available varieties in the market. The present study was carried out with five treatments including control T1 and shrikhand prepared from cow milk chakka with different levels of Calcutta betel vine leaves extract i.e. 2.0%, 4.0%, 6.0% and 8.0% in treatment T2, T3, T4 and T5, respectively. The results showed that, the mean score of flavour of shrikhand in treatment T4 was highest (8.5) and lowest was recorded in T5 (5.0). The mean score for body and texture of shrikhand was highest in T4 (8.5) and lowest in T5 (5.2). In terms of colour and appearances, the highest score was recorded in T4 (8.5) and lowest in T5 (5.5). The highest overall acceptability score was recorded in T4 (8.5) over other treatments This superiority was found due to the addition of 6.0% betel vine leaves extract in Shrikhand. It is concluded that, shrikhand of acceptable quality can be prepared by adding 6.0% Calcutta betel vine leaves extract.
