Enhancing nutritional status, growth, and fruit quality of dried figs using organic fertilizers in rain-fed orchards: A case study in Estahban, Iran.

The majority of Iranian fig production is exported, making it one of the world's most well-known healthy crops. Therefore, the main objective of the current experiment was to investigate the effects of various types of organic fertilizers, such as animal manure (cow and sheep), bird manure (partridge, turkey, quail, and chicken), and vermicompost, on the nutritional status of trees, vegetative and reproductive tree characteristics, fruit yield, and fruit quality traits in dried fig cultivar ("Sabz"). According to the findings, applying organic fertilizers, particularly turkey and quail, significantly improves vegetative and reproductive characteristics. However, other manures such as sheep, chicken, and vermicompost had a similar effect on the growth parameters of fig trees. Additionally, the findings indicated that except for potassium, use of all organic fertilizers had an impact on macro and microelements such as phosphorus, nitrogen, and sodium amount in fig tree leaves. Also, based on fruit color analysis in dried figs, the use of all organic fertilizers improved fruit color. Moreover, the analyses fruit biochemical showed that the use of some organic fertilizers improved that TSS and polyphenol compounds such as coumarin, vanillin, hesperidin gallic acid and trans frolic acid. In general, the results indicated that the addition of organic fertilizers, especially turkey manure, led to increased vegetative productivity and improvement in the fruit quality of the rain-fed fig orchard.

Adductor Canal Block Versus Femoral Nerve Block in Total Knee Arthroplasty: Network Meta-Analysis.

The quality of postoperative analgesia in total knee arthroplasty is crucial for patient recovery, rehabilitation, and hospital stay duration. In line with the above, а single-shot adductor canal block has been considered as an improved method over continuous femoral nerve block. However, continuous adductor canal block and single-shot femoral nerve block have been not adequately addressed in the discussion. This study aimed to compare the effectiveness of various types of adductor and femoral nerve blocks on clinically relevant outcomes in patients following total knee arthroplasty. A systematic review and network meta-analysis were conducted following "PRISMA-NMA" and Cochrane Handbook guidelines. The eligibility criteria included randomized trials and, where these were lacking for a comparison, nonrandomized studies involving adults undergoing primary total knee arthroplasty, comparing single-shot adductor canal block, continuous adductor canal block, single-shot femoral nerve block, and continuous femoral nerve block. A total of 36 studies involving 3308 patients were included. Single-shot adductor canal block showed higher pain scores and opioid consumption but better functional recovery at 24h compared with continuous femoral nerve block. However, this trend vanishes by the 48h assessment postsurgery. Continuous adductor canal block required higher opioid consumption but better functional recovery and shorter hospital stay compared with continuous femoral nerve block. Single-shot adductor canal block showed higher pain scores but comparable opioid consumption and functional recovery to continuous adductor canal block. The shift from continuous femoral nerve block to single-shot adductor canal block as the preferred method for pain relief after total knee arthroplasty may be premature. While the latter improves mobility, it falls short in pain control and does not shorten hospital stays. Continuous adductor canal block shows promise but is currently underappreciated, and single-shot femoral nerve block is often overshadowed by other techniques in regional anesthesia. Further high-quality, multicenter randomized controlled trials are needed to validate these findings.

The Combination of Afatinib With Dasatinib or Miransertib Results in Synergistic Growth Inhibition of Stomach Cancer Cells.

Of various human epidermal growth factor receptor (HER) inhibitors, only the anti-HER2 monoclonal antibody (mAb) Herceptin/trastuzumab and the antibody-drug conjugate trastuzumab deruxtecan (T-Dxd) has been approved for the treatment of patients with stomach cancer. However, the duration of response may be short in many patients, with tumor heterogeneity being one contributing factor. We investigated the effect of various types of targeted agents on growth in vitro and migration of a panel of human stomach cancer cells (HSCCLs) and the impact of cell proliferation rate on the anti-tumor activities of these agents. We also investigated the association between the cell surface expression of the HER family members, hepatocyte growth factor receptor (c-Met), anaplastic lymphoma kinase (ALK)7 and cancer stem cell markers CD44 and CD133, and the response to the targeted agents. Of the 18 agents examined, the cyclin dependent kinase (CDK) 1/2/5/9 inhibitor dinaciclib was the most effective and inhibited the growth of all human HSCCLs at 50% inhibitory concentration (IC50) values between 9 nM to 23 nM. Of various HER inhibitors, the irreversible pan-HER family inhibitors (e.g., afatinib) were more effective than the reversible dual epidermal growth factor receptor (EGFR)/HER2 tyrosine kinase inhibitor (TKI) lapatinib and the EGFR-specific TKI erlotinib in inhibiting the growth of HSCCLs. Of agents targeting different downstream cell signaling molecules, dasatinib targeting Ab1/Src/C-Kit, trametinib targeting MERK1/2 and miransertib targeting AKT1/2/3 inhibited growth of majority of HSCCLs, with the IC50 values ranging from 2 nM to 7 µM. Many of these agents were more effective in inhibiting the growth of HSCCLs when they were proliferating at a slower rate. Treatment with neratinib, afatinib, dinaciclib, dasatinib, stattic, miransertib and paclitaxel significantly inhibited migration of stomach cancer cells. Interestingly, treatment with a combination of afatinib and dasatinib or afatinib and miransertib resulted in synergistic and additive growth inhibition of stomach cancer cells. These results suggest that treatment with a combination of these agents may be of therapeutic value in stomach cancer and warrants further investigations.

Conduct problems, hyperactivity, and screen time among community youth: Can mindfulness help?

IntroductionWhile technology continues to evolve and the prevalence of screen-based activities is rising, limited studies have investigated the effect of various types of screen time on youth behavioural problems. Further, the influence of mindfulness intervention programs on behavioural problems beyond hyperactivity is largely understudied.ObjectivesThis study aims to address a research gap by examining the associations between four types of screen time and hyperactivity and conduct problems among community youth during the pandemic. The current study also aimed to investigate the efficacy of a mindfulness-based intervention in reducing hyperactivity and conduct problems.MethodsCommunity youth aged 12-25 from Ontario, Canada, were recruited between April 2021 and April 2022 (n=117, mean age=16.82, male=22%, non-White=21%). The Mindfulness Ambassador Program, a structured, 12-week, evidence-based intervention program, was offered live, online and led by two MAP-certified facilitators. We conducted linear regression analyses using pre-intervention data to examine the unique association between the four types of screen time and behavioural problems (hyperactivity and conduct problems). The efficacy of the MAP on adolescent hyperactivity and conduct problems was examined considering the three survey time points (pre-, post-, and follow-up) using a series of linear regression models utilizing the Generalized Least Squares (GLS) Maximum Likelihood (ML), unstructured model.ResultsThe average score for conduct problems was classified within the normal range, while the average score for hyperactivity was considered borderline at baseline. More than 5 hours of playing video games were significantly associated with increased conduct problems [β= -1.75, 95% CI=-0.20 – 3.30, p=0.03]. Accounting for age, sex, baseline mental health status, and screen time, the mindfulness intervention program significantly contributed to decreased hyperactivity at post-intervention compared to the baseline [β=-0.49, 95% CI=-0.91 to -0.08, p=0.02]. It was maintained at follow-up [β=-0.64, 95% CI=-1.26 to -0.03, p=0.04].Conclusions Our findings suggest an adverse impact of excessive video gaming on behavioural problems among community youth and confirm that the trend remains the same. Considering the simplicity, brevity, non-invasive nature and other mental health benefits of the mindfulness intervention, we argue that the results are promising and worthy of further study and larger-scale implementation. Clinicians, parents, and educators should work collaboratively to provide developmentally appropriate strategies to moderate screen time spent on video games among youth.Disclosure of InterestNone Declared

Higher-order Aberrations — the Choice of Optimal Intraocular Correction in the Surgical Treatment of Cataracts. Review of the Literature

The cornea is the most powerful refractive element of the eye and plays a fundamental role in the quality of vision. Imperfection of corneas shape leads to the focusing errors formation, known as optical aberrations, which are responsible for visual performance deterioration. Understanding and assessing wavefront errors in IOL selection and calculation is great importance to achieve maximum optical outcome in the postoperative period. The article presents literature data of the effect of higher-order aberrations on the vision quality in unoperated eyes, changes of the wavefront in the eyes after cornea surgical interventions, the effect of various types of IOLs (spherical, aspherical, multifocal and EDOF) on the total error of the eye wavefront, recommendations at their choice with different severity levels of optical aberrations, as well as promising areas of research on this issue.

EFFECT OF WHITE SUGAR, BROWN SUGAR AND JAGGERY POWDER SYRUP ON BIOCHEMICAL AND HISTOPATHOLOGICAL MARKERS OF SPRAGUE-DAWLEY RATS

Hypertension accounts for 10% of the total annual health budget in developed countries.1 By 2025, the number of people living with hypertension is expected to reach 1.56 billion people.2Dietary factors that increase blood pressure (BP) are of interest to public health authorities.3,4Twenty adult male Sprague-Dawley rats were taken. All groups received standard chow ad libitum. Controls (A), received plain drinking water, and the Sucrose treatment rats received 10% sucrose solution prepared daily for 12 weeks. Non-invasive blood pressure was recorded using computer based data recording system power lab model: M-ML 856, Australia with rat tail cuff attachment.Blood samples were collected. Serum aliquots were frozen at ?80°C for: ALT, AST, TG, total cholesterol (TC), and high-density lipoprotein (HDL) were determined using commercial enzymatic methods (CELM diagnosis, São Paulo, Brazil). The concentration of VLDL and low-density lipoprotein was measured. ANOVA and Post-Hoc Tukey tests were applied to determine statistical difference among the study groups. The results showed variable effects on biochemical and histopathological findings in rat liver, kidney and pancreas. The pancreas and kidneys of the rats showed adverse inflammatory histopathological changes maximally in rats taking jaggery syrup (Shakkar) flowed by white sugar and minimal in Shakkar. The adverse effects on liver cells were maximally seen on rats given brown sugar. This study enabled us to better understand the biochemical and histopathological effects of various types of sugars available in Pakistani market in order to create awareness regarding their effects on health.

CARCINOGENIC EFFECT OF VARIOUS TYPES OF SMOKE

All types of smoke are carcinogenic. Increasing air smoke is a serious global problem. Knowledge on carcinogenic effects of various types of smoke is necessary to work out effective preventive measures.
 The purpose of the review is to characterize the general characteristics and peculiarities of the carcinogenic effects of various types of smoke. The most significant carcinogens of all types of smoke are polycyclic aromatic hydrocarbons, heavy metals and carbon microparticles. Any smoke is an etiological factor for respiratory tract cancer, and systemic neoplasms (tumors of hematopoietic and lymphoid tissues, central and peripheral nervous systems, soft tissues and skeleton). Tobacco smoke may be involved in the pathogenesis of cervical cancer due to the induction of local immunosuppression and specific tropic nitrosamines. Exhaust fumes due to high benzene content may cause hematological malignancies, especially leukemia in children. Wildfire smoke, due to significant amounts of ultra-fine carbon particles PM0.1, contributes to the development of central nervous system tumors. Severe contamination with natural and artificial radionuclides makes wildfire smoke a factor of high carcinogenic danger for the human population globally. Prevention of malignant neoplasms caused by smoke requires government measures to promote smoking cessation, hybrid and electric engines in automobiles, as well as wildfire prevention, early detection and extinction. Effective respirators and indoor air filters should be used for personal protection. To relieve environmentally caused oxidative stress, herbal medicines and food products that stimulate autophagy, as well as transfer factors for immunodeficiency correction, are recommended.

The Impact of Nanomaterials on Photosynthesis and Antioxidant Mechanisms in Gramineae Plants: Research Progress and Future Prospects.

As global food security faces challenges, enhancing crop yield and stress resistance becomes imperative. This study comprehensively explores the impact of nanomaterials (NMs) on Gramineae plants, with a focus on the effects of various types of nanoparticles, such as iron-based, titanium-containing, zinc, and copper nanoparticles, on plant photosynthesis, chlorophyll content, and antioxidant enzyme activity. We found that the effects of nanoparticles largely depend on their chemical properties, particle size, concentration, and the species and developmental stage of the plant. Under appropriate conditions, specific NMs can promote the root development of Gramineae plants, enhance photosynthesis, and increase chlorophyll content. Notably, iron-based and titanium-containing nanoparticles show significant effects in promoting chlorophyll synthesis and plant growth. However, the impact of nanoparticles on oxidative stress is complex. Under certain conditions, nanoparticles can enhance plants' antioxidant enzyme activity, improving their ability to withstand environmental stresses; excessive or inappropriate NMs may cause oxidative stress, affecting plant growth and development. Copper nanoparticles, in particular, exhibit this dual nature, being beneficial at low concentrations but potentially harmful at high concentrations. This study provides a theoretical basis for the future development of nanofertilizers aimed at precisely targeting Gramineae plants to enhance their antioxidant stress capacity and improve photosynthesis efficiency. We emphasize the importance of balancing the agricultural advantages of nanotechnology with environmental safety in practical applications. Future research should focus on a deeper understanding of the interaction mechanisms between more NMs and plants and explore strategies to reduce potential environmental impacts to ensure the health and sustainability of the ecosystem while enhancing the yield and quality of Gramineae crops.

Effect of two different peritoneal dialysis modalities on wound infection in peritoneal dialysis patients: A meta-analysis.

Peritoneal dialysis(PD) is one of the most efficient methods in end-stage kidney disease, and it is very important for PD to perform well. No research has been conducted to evaluate the effect of various types of PD catheters on the prognosis of post-operative wound complications. While recent meta-analyses are in favour of straight tubing, there is still uncertainty as to whether direct or coiled PD is beneficial. The purpose of this meta-analysis was to compare the efficacy of direct and coiled PD catheters on the incidence of post-operative wound infection, bleeding and peritonitis. A comprehensive search was carried out on three databases, including PubMed and Embase, and a manual search was carried out on the links in the paper. The results showed that the incidence rate of bleeding after operation and the degree of infection among the straight and coiled pipes were compared. The results showed that there were no statistically significant differences in the incidence of post-operative wound infection among straight PD patients with coiled PD (OR, 0.79; 95% CI, 0.58-1.08 p = 0.13). No statistical significance was found in the case of PD with coiled tubing compared with that of straight PD group in wound leakage (OR, 1.17; 95% CI, 0.71-1.93 p = 0.55). No statistically significantly different rates of post-operative peritonitis were observed for coiled tubing compared with straight ones in PD patients (OR, 1.06; 95% CI, 0.78-1.45 p = 0.7). There is no statistical significance on the rate of wound infection, wound leakage and peritonitis among coiled and straight tube in PD.

Investigation of type, size, and dosage effects of superabsorbent polymers on the hydration development of high-performance cementitious materials

The low water-to-binder ratio commonly used for high-performance cementitious materials is known to limit the degree of hydration of their cement particles. This issue often cannot be resolved with conventional external curing methods, primarily because of the low permeability of such materials. Thus, internal curing methods are devised to improve the degree of hydration and maximize the use of cement particles. Focusing on superabsorbent polymers (SAPs) as one of the main internal curing agents, this study investigates the effects of various types, sizes, and dosages of SAPs on the hydration kinetics of high-performance cementitious mixtures. For this purpose, the main performance characteristics of SAPs were characterized first. Paired with monitoring the temperature development patterns in a set of SAP-contained mixtures, thermogravimetric analyses (TGA) and X-ray diffractometry (XRD) investigations were systematically performed to measure the phase consumption of cement particles. Scanning electron microscope (SEM) image analyses were then employed to assess the materials deposited in the remaining SAP voids. By providing original insights into the hydration development process, this study’s outcome guides the use of SAPs with the ultimate goal of maximizing the hydration degree of cement particles, paving the way to minimizing the carbon footprint of high-performance cementitious materials.

Effect of Various Types of Sugars on Antioxidant Activity and Physico-chemical Properties of Kombucha Fermented Whey

Kombucha or known as SCOBY (Symbiotic Culture of Bacteria and Yeast) is a fermented tea beverage with the addition of sugar then fermented for 7-14 days. Recent studies showed kombucha conceivably used for milk fermentation, such as fermented whey, yogurt, and fermented milks. Sugar is added to kombucha as carbon source for microorganisms in kombucha. Type of sugar, sugar concentration, tea concentration, temperature and incubation time are factors that affect kombucha fermentation. The aims of this study were to determine the effect of various types of sugars on antioxidant activity (2,2-diphenyl-1-picrylhydrazyl (DPPH)) and physicochemical properties (pH, titratable acidity, total dissolved solid, and CIE L* a* b* color space value). The various types of sugars were granulated white sugar (G1), coconut sugar (G2), palm sugar (G3) and no sugar addition as control (G0). Fermented whey using 10% kombucha liquor, 3% kombucha cellulose and 10% sugar addition, whey then fermented at 37oC for 14 hours. Result demonstrated that using of various types of sugars significantly affected antioxidant activity, CIE L*a*b* color space value, pH, titratable acidity, total dissolved solid and vitamin C content. The highest vitamin C content was G3 (0.91±0.05 mg/100ml), kombucha fermented whey using palm sugar. Any type of sugar could be used on kombucha fermented whey, and the highest antioxidant activity (DPPH) was fermented whey kombucha with the addition of coconut sugar (G2) (86.79±10.94%).

Causal effects of various types of physical activities on psychiatric disorders: a Mendelian randomization study.

Psychiatric disorders (PD) pose a significant burden, with vast prevalence and mortality, inflicting substantial costs on individuals and society. Despite its widespread prevalence, the complex pathogenesis of PD remains elusive, leading to limited and challenging therapeutic development. An emerging risk factor for chronic diseases, prolonged sedentary behavior, contrasts with the therapeutic potential of exercise, regardless of its intensity, for various ailments, including PD. Yet, the diversity in exercise modalities and intensities may offer varied impacts on health. This study, leveraging Mendelian Randomization (MR), seeks to investigate the causal relationship between exercise and PD, aiming to elucidate the optimal exercise modality and intensity for PD mitigation while addressing potential confounders. This study employed a Mendelian randomization analysis using the genome-wide association study (GWAS) database to investigate the causal relationship between types of physical activity and psychiatric disorders. Sensitivity analysis was conducted to demonstrate the reliability and robustness of the results. In the past 4 weeks, engaging in a substantial amount of DIY physical activity was found to have a causal relationship with psychiatric disorders (IVW: OR = 0.228, 95% CI: 0.113-0.461, P = 0.000038). As for the types of exercises, there may be a potential causal association between aerobic training (including swimming, cycling, fitness, and bowling) and psychiatric disorders (IVW: OR = 0.322, 95% CI = 0.148-0.704, P = 0.004). However, there was no causal relationship found between mild DIY physical activity and psychiatric disorders (IVW: OR = 0.918, 95% CI = 0.417-2.021, P = 0.831). Furthermore, it seems that there is no causal relationship between vigorous exercise and psychiatric disorders (IVW: OR = 2.705, 95% CI = 0.081-3.419, P = 0.578). Our study confirms that only a certain level of training activity can have a protective effect on psychiatric disorders, while mild physical activity or vigorous training does not have an impact on psychiatric disorders.

Chloride penetration resistance of ultra-high performance concrete with various multi-walled carbon nanotubes

Ultra-high performance concrete (UHPC) with outstanding chloride penetration resistance (CPR) exhibits excellent prospects for extending the service life of structures in the marine environment. This study investigates the effects of various types and contents of multi-walled carbon nanotube (MWCNT) on the CPR of UHPC, including pristine MWCNT with different sizes, MWCNT with surface modification, and MWCNT with special structures. The results show that 0.25% thick-short pristine MWCNT, 0.5% short hydroxyl functionalized MWCNT, and 0.25% helical MWCNT show more significant enhancement effect, improving the CPR by 74.14%, 72.91%, and 77.17%, respectively. The correlation analysis results suggest a negative linear correlation between the CPR and pore volume of the composites. The C-S-H gels and small capillary pores with a diameter below 50 nm are the significant factors determining the CPR of the composites. This illustrates that the CPR enhancement effects of various types of MWCNT change with the refinement of pore structure of UHPC. The enhancing mechanisms can be attributed to the nano-core effects of MWCNT, reducing the CH crystal size and primary cracks, inhibiting the growth and propagation of microcracks, refining the pore structure, optimizing the compactness of the cement paste matrix and interfacial transition zone, thus reducing the channels for chloride ion diffusion, while increasing the constrictivity and tortuosity of the channels.

Comparison study between single enzyme and multienzyme complex in distiller's dred grains with soluble supplemented diet in broiler chicken.

Upregulation of the nutritional value of feed is the major target of various studies in the livestock industry, and dietary enzyme supplementation could aid in digesting the nondegrading nutrients of grains in feed ingredients. Dried distillers' grains with solubles (DDGS) is a byproduct of the fermentation process in the beverage industry and can be used as a large supply source of fiber in feed. Therefore, we conducted an experiment with male broiler chickens to investigate the effect of various types of enzymes on DDGS and compare the efficacy of single enzyme and multienzyme complexes on growth performance and gut environments in broiler chickens. We used 420 1-day-old broiler chickens (Ross 308), and they were allotted into 4 dietary treatments with seven replications (CON, corn-soybean meal [SBM] diet; NC, DDGS supplemented diet; SE, 0.05 % of mannanase supplemented DDGS-based diet; MC, 0.10% of multienzyme complex (mannanase and xylanase, glucanase) supplemented DDGS-based diet. The dietary exogenous enzyme in the DDGS-supplemented diet could improve growth performance as much as the growth of the control group, and digestibility of dry matter, crude protein, and gross energy were significantly increased by enzyme addition in groups of chicks fed DDGS-supplementation diet. Moreover, the populations of pathogenic bacteria, coliforms, and Bacteroidetes were significantly decreased by enzyme supplementation, which might lead to improved gut mucus-secreting cells and inflammatory cytokines in the jejunum. Collectively, dietary single enzyme and multienzyme complexes could improve gut environments, including intestinal immune responses and gut microbial population, and lead to improvement of growth performance in broiler chickens.

Investigating the impact of company announcements on stock prices: an application of machine learning on Australian lithium market

This paper investigates the effects of various types of announcements made by lithium producers on stock prices. We collected data from 40 lithium-producing companies listed on the world's largest stock exchanges, spanning from May 2020 to September 2022. To analyze the impact of announcements such as quoted and unquoted securities, market announcements, company reports, public meetings and presentations, financial announcements, and technical announcements on stock prices, we employed an extreme gradient boosting (XGBoost) model. Our results indicate that stock exchange market announcements and announcements about public meetings and presentations significantly influenced the stock prices of all eight large-cap companies studied. Announcements about public meetings and presentations were crucial predictors of stock prices for 73% of all companies analyzed. Additionally, positive financial announcements were key predictors for 70% of the companies. These findings suggest that investors should consider these predictors when making investment decisions in the lithium-related stock market. This study contributes to the existing literature by providing empirical evidence on the impact of different types of announcements made by lithium producers on stock prices. Furthermore, the XGBoost model used in this study can be applied to other industries and markets to analyze the impact of various types of announcements on stock prices.

20(S)-Ginsenoside Rh2 inhibits hepatocellular carcinoma by suppressing angiogenesis and the GPC3-mediated Wnt/β‑catenin signaling pathway.

20(S)-Ginsenoside Rh2 has significant anti-tumor effects in various types of cancers, including human hepatocellular carcinoma (HCC). However, its molecular targets and mechanisms of action remain largely unknown. Here, we aim to elucidate the potential mechanisms by which Rh2 suppresses HCC growth. We first demonstrate the role of Rh2 in inhibiting angiogenesis. We observe that Rh2 effectively suppresses cell proliferation and induces apoptosis in HUVECs. Furthermore, Rh2 significantly inhibits HepG2-stimulated HUVEC proliferation, migration and tube formation, accompanied by the downregulation of VEGF and MMP-2 expressions. We also reveal that Rh2 inhibits HCC growth through the downregulation of glypican-3-mediated activation of the Wnt/β-catenin pathway. We observe a dose-dependent inhibition of proliferation and induction of apoptosis in HepG2 cells upon Rh2 treatment, which is mediated by the inhibition of glypican-3/Wnt/β-catenin signaling. Moreover, downregulation of glypican-3 expression enhances the effects of Rh2 on the glypican-3/Wnt/β-catenin signaling pathway, resulting in greater suppression of tumor growth in HepG2 cells. Collectively, our findings shed light on the molecular mechanisms through which Rh2 modulates HCC growth, which involve the regulation of angiogenesis and the glypican-3/Wnt/β-catenin pathway. These insights may pave the way for the development of novel therapeutic strategies targeting these pathways for the treatment of HCC.

Final assessment of multifactor experiments of heat transfer in the underwater wet welding

The multifactorial nature and interconnection of phenomena occurring during welding, especially under water, are important for deepening knowledge in this area. An analysis of the research carried out and the solutions obtained in the field of underwater wet welding of low-carbon steels shows that in this area, adequate assessments of the effectiveness of various types of welding with comprehensive consideration of the interaction of various physical phenomena, significantly different in nature from each other, have not been obtained. Integrated approaches to the assessment and analysis of heat transfer coefficients from the side of the arc combustion surface and from the opposite side are proposed. For the first time, the potential values were calculated as a change in the values of heat transfer indicators for various welding conditions based on verified experimental data. The ultimate goal of the work is to calculate the cooling rates of the metal of the welded joint, which will subsequently make it possible to predict the mechanical properties of the weld metal and the likelihood of the formation of hardening structures.

Pengendalian Kutu Beras (Sitophilus oryzae l.) Secara Organik

Rice weevils can cause damage to rice in warehouses, so it is necessary to control them in an environmentally friendly manner. The aim of this research was to determine the effect of various types of organic pesticides used on rice weevils (Sitophilus oryzae L.). This study used a completely randomized design (CRD), consisting of 6 treatments applied during the imago stage. Each treatment consisted of 4 replications so that the experimental units obtained were 24 experiments. The results of the research show that the use of vegetable pesticides has the potential to kill rice weevils. Mortality observations obtained very significantly different results, where the open eco enzyme (TT) treatment with a percentage of 72.50% was a treatment that had an influence on rice weevil mortality. All treatments were able to kill rice weevils. from percentage 35 to 72.5. All botanical pesticides used can suppress the rice weevil population for up to 4 weeks after application and there is an increase thereafter and repeated applications are necessary to suppress the population.

Results: in this study, a total of 56 adult participants of both sexes with intellectual disabilities (ID) were initially enrolled (n=56). Following the intervention, the final sample size was 48 participants. Notably, the participants in the yoga group demonstrated a statistically significant (p<0.05) improvement in pulmonary function parameters when compared to the control group. These findings suggest a positive impact of the yoga intervention on pulmonary function, highlighting its potential as a beneficial therapeutic approach for individuals with intellectual disabilities. The observed improvements underscore the significance of incorporating yoga into interventions aimed at enhancing respiratory well-being in this population. Conclusion: in conclusion, this randomized controlled study offers valuable insights into the effects of various types of yoga practice on the pulmonary function of healthy young adults with intellectual disabilities. The positive outcomes observed underscore the potential of yoga as an effective intervention for enhancing pulmonary function in individuals with intellectual disabilities. These findings contribute to the growing body of evidence supporting the integration of yoga into interventions aimed at promoting respiratory well-being in this population. Further research and exploration of specific yoga practices may provide additional tailored approaches for optimizing the respiratory health of individuals with intellectual disabilities.

Study on the Compressive and Flexural Properties of Coconut Fiber Magnesium Phosphate Cement Curing at Different Low Temperatures.

The incorporation of coconut fiber (CF) into magnesium phosphate cement (MPC) can effectively improve upon its high brittleness and ease of cracking. In practical engineering, coconut fiber-reinforced magnesium phosphate cement (CF-MPC) will likely work in cold environments. Therefore, it is essential to understand the effects of various types of low-temperature curing on CF-MPC performances, but there are very few studies in this area. In this study, the static compression and three-point bending test were utilized to examine the compressive and flexural characteristics of CF-MPC with various CF contents and different negative curing temperatures. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were conducted to observe the impact of low-temperature maintenance on the structure and hydration reaction of the specimens. The results indicate that CF-MPC curing at low temperatures was more prone to cracks during compression and bending, while the appropriate amount of CF could enhance its plastic deformation capability. The CF-MPC's compressive and flexural strength declined as the curing temperature dropped. Moreover, with the rise in CF content, the samples' compressive strength also tended to fall, and there was a critical point for the change in flexural strength. In addition, MPC's primary hydration product (MgKPO4·6H2O) decreased with a drop in curing temperature, and more holes and fractures appeared in CF-MPC.
