Starting a robotic thoracic surgery program: From wedge resection to sleeve lobectomy in six months. Initial conclusions

IntroductionRobot-assisted thoracic surgery (RATS) is a rapidly expanding technique. In our study, we aimed to analyze the results of the process to adopt robotic surgery in our Department of Thoracic Surgery. MethodsThis is an intention-to-treat analysis of a series of consecutive patients operated on using the RATS approach in our hospital from January 2021 to March 2022. Data were registered for patient characteristics, type of surgery, operative times, conversion rate, chest tube duration, length of hospital stay and complications.The IBM SPSS® statistical software was used for the statistical analysis. A cumulative sum analysis of the operating time was performed to define the learning curve. ResultsDuring the study period, 51 patients underwent robotic surgery, including pulmonary and non-pulmonary interventions. In addition, 15 patients (29.4%) underwent non-pulmonary interventions: one pleural (2%), 2 diaphragmatic (3.9%), and 12 mediastinal (23.5%). Among the mediastinal surgeries, one conversion was necessary (8.3%) for a complex vascular malformation, and 11 were completed by RATS, including 7 (58.3%) thymomas, 3 (25%) pleuro-pericardial cysts, and one (8.3%) neurogenic tumor. Mean operative time was 141 min (104–178), mean chest tube duration was 0.9 days (0–2), and mean length of stay was 1.45 days (1–2).Thirty-six patients underwent lung surgery (70.6%). The complete RATS resections (34; 94.4%) included: 3 wedge resections (11.1%), 2 segmentectomies (3.7%), 28 lobectomies (81.5%), and one sleeve lobectomy (3.7%). Mean surgery time was 194.56 min (141–247), chest tube duration was 3.92 days (1–8), and length of stay was 4.6 days (1–8). Complications occurred in 4 patients (11.1%). No 90-day mortalities were registered. ConclusionsThe implementation of RATS was achieved with good clinical results and operative times for all indications. A rapid learning curve was accomplished in short time. Previous VATS experience, patient selection, team training and program continuity are fundamental to successfully develop a RATS program.

Differences in Quality of Female Nursing Work Life Based on Gender and Nursing Perspectives

The quality of a nurse’s work life is the degree of satisfaction regarding personal and organizational needs based on experience in a work organization. A nurse with a dual role is the nurse who acts as a mother and a professional nursing staff at the same time. The purpose was to determine differences in the quality of female nurses’ work life in gender and nursing perspective at Balung General Hospital and Kalisat General Hospital in Jember Regency. The research method uses a comparative study with a quantitative research type. The sampling technique in this research is random sampling with a total of 115 samples. Data collection was conducted by using questionnaires about the quality of nurses’ work life from the nursing perspective and questionnaires conflict with women’s dual role from the gender perspective. Data processing using the Mann-Whitney analysis test with a 95% significance level (α=0.05). The results using Mann-Whitney analysis showed that there is a difference between the gender perspective and the nursing perspective (p=0.000). The mean results showed that the nursing perspective () is higher than the gender perspective (). The conclusion shows that the quality of female nursing work life from the gender perspective needs to be improved. The hospital needed to review further regarding work schedules and shift time; the family needed to provide full support and good cooperation; and female nurses themselves must also have good coping control, time, and energy management. Apart from that, it is necessary to have a policy from the room head and team leader regarding the distribution of schedules for female nursing staff without reducing the feeling of unfairness for male health workers.

Synergistic effects of Pd-Ag decoration on SnO/SnO2 nanosheets for enhanced hydrogen sensing

Hydrogen, the lightest and most abundant element in the universe, holds immense importance across various fields of application from industry to healthcare. Detecting hydrogen is crucial in medical diagnostics and leak detection, as it helps diagnose gastrointestinal conditions and ensures safety in industrial settings by identifying potential leaks in hydrogen-based systems. In this study, we present the synthesis of tin oxide (SnO/SnO2) nanosheets using a facile hydrothermal method followed by the decoration of Pd-Ag alloy nanoparticles (NPs) for the purpose of hydrogen gas detection. Different combinations of Pd and Ag in Pd-Ag alloy NPs were tested on the surface of the SnO/SnO2 nanosheets in order to optimize their catalytic properties for enhanced hydrogen gas sensing. The Pd-Ag alloy NPs with a ratio of 1:0.5 decorated on SnO/SnO2 nanosheets (Pd1Ag0.50@SnO/SnO2), exhibited the highest response (s = Ra/Rg) of 81.34 at an optimum temperature of 225 °C compared to the bare SnO/SnO2 nanosheets. The fabricated sensor also showed an excellent level of selectivity, repeatability, and a good response time (45 s). The enhanced sensing response of Pd1Ag0.50@SnO/SnO2 towards hydrogen is explained using the spillover and electronic sensitization mechanism. The combined gas sensing mechanism is discussed in detail.

Application of free serratus anterior muscle-fascial composite tissue flap and facial lipofilling in repairing progressive hemifacial atrophy

IntroductionProgressive hemifacial atrophy (PHA) is a nonnegligible disease, and its treatment currently lacks consensus. We aim to conduct an analysis of PHA patients to summarize the postoperative effect. Moreover, we introduced the free serratus anterior muscle-fascial composite tissue flap as a safe and novelty surgical procedure for moderate-severe PHA. MethodsThis clinical study included four patients who received a free serratus anterior muscle-fascial composite tissue flap and 19 patients who received Coleman fat transplantation. Preoperative (preoperative photograph and imageological examination) and postoperative (postoperative photograph, complications, therapeutic effect, and satisfaction) assessments were performed for all PHA patients. Body Image Concern Inventory (BICI), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) were performed preoperatively and postoperatively. ResultsAll the cases were cured with a good appearance with two kinds of operations. Free serratus anterior muscle-fascial composite tissue flap could correct face defects in one surgery and achieve good long time and short-time postoperative satisfaction in moderate-severe PHA. Fat transplantation could also enhance appearance in numerous operations for mild-moderate PHA. The volume of free-fat grafts decreased obviously after implantation in many cases. So, many patients (42.11%) accepted a series of operations to achieve satisfied postoperative effect. BICI, SAS, SDS score decreased a year later in all patients. ConclusionFree serratus anterior muscle-fascial composite tissue flap transplantation is an effective and safe treatment for moderate to severe PHA.

Formulation and Evaluation of Cetrimide Based In situ Gelling System for Ocular Drug Delivery

Conventional drug delivery system is a traditional type of drug delivery system which manifests poor bioavailability of drug due to tear turn over, tear flow and blinking of eye which causes removal of drug at the ocular surfaces. To overcome from the drawbacks of conventional drug delivery system In- situ gels come into the fashion of ocular drug delivery system for the treatment of ocular diseases which have enhanced bioavailability and better for patient’s compliance. The goal of the present work to express formulation and evaluation of cetrimide in situ gels which have anti-fungal activity used in the treatment of fungal keratitis caused by Fusarium solani. Carbopol 934 is used as viscosity enhancing property. Xanthan gum was used as thickening and stabilizing agent. Sodium alginate was used for gelation ability. The combination of carbopol and xanthan gum showed good gelling capacity and gelation time up to 6hrs period. The developed formulation of cetrimide in situ gels was stable non -irritant which are feasible substitute for conventional drug delivery system such as eye drops by virtue of its stability to increase residence time of drug at the ocular surfaces and provide sustained release of drug with increase bioavailability and better for patient’s compliance.

Brand advertising competition across economic cycles

This study investigates how brands’ responses to competitors’ advertising actions change over the business cycle. In an empirical analysis of advertising activity by 105 brands in six consumer packaged goods categories over 10 years in a market that experienced severe economic swings, we show that managers become more aggressive in contractions. Brands respond not only more often to competitors’ advertising but also more intensely. Different brands react in contractions. Brand leaders respond less often and intensely in bad times; by contrast, premium-tier brands seem to avoid competition in good times but aggressively defend their position in bad times, especially against cheaper competitors, which are more popular in contractions. We corroborate the validity of our findings through in-depth interviews with executives and introduce two useful metrics, aggressivity and receptivity, to map changes in brand competition in an industry when economic conditions change. Collectively, the findings show how managers can better anticipate competitive advertising reactions in good and bad economic times.

Hematological Activity in Primary Antiphospholipid Syndrome: A Common Manifestation Outside the Classification Criteria

Introduction: Thrombocytopenia and autoimmune hemolytic anemia (AIHA) are extra-criteria manifestations of antiphospholipid syndrome (APS). They have a higher incidence in secondary cases, and there is little information on primary antiphospholipid syndrome (pAPS). Aim: To evaluate the clinical characteristics and profile of antibodies in pAPS with hematological activity. Material and methods: A retrospective study included patients with pAPS, diagnosed according to the Sapporo criteria with follow-up at third level of care in Mexico City from 1990 to 2021. Descriptive statistics were used, and chi-squared test, Mann-Whitney U test, and logistic regression were performed. Results: A total of 97 patients with pAPS were included; 73.2% (71) were women with a mean age of 33.9 + 11.5 years and a mean follow-up of 132 months (24-360). We found that 77% (75) presented thrombotic and 37% (36) obstetric manifestations. In 68% (66) of patients, hematological manifestations (non-exclusive groups) were found. Further, 63.9% had thrombocytopenia, the most common kind being severe, and a minority had AIHA in 13.4%. Table 1 describes the clinical manifestations. Patients with thrombocytopenia were younger, with 32 + 10.3 years vs 37 + 13 years ( p = 0.046). A total of 59.7% (37) had a triple marker. In comparison with patients without thrombocytopenia, 69.4% (43) presented positive lupus anticoagulant vs 48.6% ( p = 0.043) and OR 2.5 (CI 95% 1.06-6.1). An 83.9% (52) had positive IgG anticardiolipin vs 62.9% ( p = 0.019), OR 3.21 (CI 95% 1.19-8.63) with a higher titer of 19.4 vs 6.1 ( p = 0.017) and OR 1.01 (CI 95% 0.99-1.04). They had higher titers of antiβ2 glycoprotein-I IgM of 6.8 vs 5.2 ( p = 0.019) with OR 1.03 (CI 95% 0.99-1.06) and of antiphosphatidyl serine/prothrombin IgM of 52.8 vs 16.8 ( p = 0.004), OR 1.01 (CI 95% 1- 1.02). In patients with AHAI, anti-β2 glycoprotein-I IgM antibody titers of 7.1 vs 5.9 were identified, which were higher compared with those who did not present it ( p = 0.026). Those without hematological activity had more thrombosis ( p < 0.001). When comparing the groups with and without thrombosis, we observed that those with thrombosis had lower titers of antiβ2 glycoprotein-I IgM in 5.8 vs. 7.4, p = 0.036, OR 0.97 (CI 95% 0.94-1) and higher anti-phosphatidyl serine/prothrombin titers in 61.2 vs 12.1, p = 0.021 with OR 1.02 (CI 95% 1-1.04). A total of 76.3% (74) received anticoagulant and 24.7% (24) received antiplatelet. Immunosuppression was prescribed in 38.1% (37). Those with severe thrombocytopenia received: prednisone in 54.5% (18) of cases, methylprednisolone in 36.4% (12), rituximab in 3% (1), and splenectomy in 36.4% (12). In patients with AHAI, 84.6% (11) received immunosuppressants and 46.2% (6) underwent splenectomy. Conclusion: A higher incidence of hematological activity was identified in pAPS, mostly in young women. The most common kind was severe thrombocytopenia, as opposed to what was described in literature as mild to moderate. Differences were found regarding the titer and positivity of antibodies. With thrombocytopenia, there was a higher frequency of positive lupus anticoagulant, anticardiolipin IgG and antiβ2 glycoprotein-I IgM with higher titers. Patients had anti-phosphatidyl serine/prothrombin antibodies as an extended panel and a correlation with hematological activity was identified. Knowing the serology of pAPS is useful to identify in good time patients who may present severe hematological manifestations. No patient died of a hematologic complication; however splenectomy was required in some cases. To our knowledge this is one of the few studies that evaluate hematological manifestations in pAPS.

There has to be a better way

With your laptop open in front of you, you’re ready to take notes on the new teaching intervention being introduced at today’s session. You’re feeling distracted by the research ideas you wanted to work on this morning, and the assessment grading you need to finish this afternoon. Today wasn’t a good time to focus on course development, but it was the only time this professional development session was being offered. At the end of the session you leave with a collection of notes, some great ideas, and the enthusiasm to implement changes that really make a difference. You go back to your grading, your research, and your teaching. Weeks later you look at your notes and wonder how you’re going to actually make those changes. There has to be a better way. As a TELedvisor, you find these one-off professional development sessions just as frustrating. Fresh teaching ideas are presented, champions share their exemplary practice, and opportunities for collaboration are provided, but often the same fully engaged academics attend each session. Overall improvement in course development across the institution doesn’t take place. You could run a day or three of focused course design sessions, if lecturers could commit to attending. You could have instructional designers develop the online or blended elements of a course, but if the teacher isn’t invested, or doesn’t understand the reasoning behind the design or the activities that have been implemented, then time-poor lecturers often teach in the way that they’ve been used to. Formal qualifications in tertiary teaching can support the development of a greater understanding, but only a few lecturers have the time or the enthusiasm to undertake these. There has to be a better way. The Academic Development team are trying something different at the University of Canterbury. We are implementing a learner centric process for professional development for teaching and course development. We have designed a flexible, blended, learner driven professional development process, in which lecturers are invited to take part. This process utilises many of the recommended practices for effective professional development (Cordingley et al.,2015; Darling-Hammond et al.,2017; Hertz et al., 2022; Richardson & Díaz Maggioli, 2018) as well as strategies we recommend for tertiary teaching, and is undertaken at a time and pace that works for the lecturer(s) of a course. Through both format and content, the process provides examples of good practice, involves lecturers in flipped learning, offers expert support, incorporates collaborative course development, and promotes reflective practice. How has this process been designed? How does it work? How is it being implemented? Is it having an impact? Commit seven minutes of your time to finding out (and bring your laptop to take notes).

The Effect of Application of Discharge Planning Seci Model on The Completeness of Discharge Planning Documentation for Tuberculosis

Background: The implementation of discharge planning must be documented completely. Preliminary study found that 90% of discharge planning implementation is not documented. The weakness of the intervention that has been done by previous researchers is that it does not focus on increasing the completeness of documentation, especially on the documentation of discharge planning, the application of discharge planning based on knowledge management SECI model as an intervention applied to improve the completeness of documentation on discharge planning. Objectives: The purpose of this study was to determine the effect of discharge planning based on knowledge management SECI model on the completeness of documentation of discharge planning for tuberculosis. Methods: This research is quantitative research with quasi-experimental approach with post-test only design with nonequivalent control group. The number of samples was 34 medical records with a diagnosis of pulmonary TB, each of which consisted of 17 samples in the control group and 17 samples in the intervention group. The intervention in this research is the implementation of discharge planning based on knowledge management SECI model. The data were taken using the discharge planning SECI model observation sheet and the documentation completeness observation sheet which had been tested by expert and analyzed using the Mann-Whitney test. Results: The results showed p value is 0.000 < 0.05. Conclusion: Application of discharge planning based on knowledge management SECI model has a significant effect on the completeness of documentation of discharge planning for tuberculosis (TB). Nurses must become to manage knowledge, good time management, and be a role model in providing nursing care.

The Effect of Tiktok Application on Teenage Behavior in the Vuca Era

TikTok is an application that is often used by teenagers in the Vuca era. Personality in the Vuca era was defined as a form of character, human behavior. because of that, the researcher intends to conduct research on the effect of the tiktok application on adolescent behavior. Through the TikTok application, teenagers express themselves through the video content they make. With the frequent circulation of TikTok content that is inappropriate to watch, it will affect the behavior of adolescents, especially teenagers who are still in puberty and who have not can distinguish between what is good. Teenagers who can still be influenced based on what they see and hear without special supervision from their parents will form a personality character that is not good because they lack social interaction and do not remember when using the tiktok application, it's not uncommon for them to often follow what they see and hear in the video content. It can be concluded that the influence of using the application Tik-Tok on adolescent behavior provides changes in behavior, mental health and social interaction in adolescents, describes how to prevent and deal with bad behavior that will arise from the TikTok application, and how to use good time for teenagers when using the TikTok application.

Teacher Strategies in Managing Chemistry Learning Time to Improve Student Learning Achievement

The purpose of this research is to find out the teacher's strategy in managing ideal and effective chemistry learning time to improve students' learning achievement. The method used is literature research using secondary data reviewed from books, articles, and journals. The results show that chemistry learning conducted during the day has an ineffective impact on students in participating in learning, such as students not focusing, tired, sleepy, hungry, thus disrupting students' learning concentration. The hot classroom conditions during the day also make it difficult for students to accept the material taught by the teacher. Thus, morning time is considered an effective time or a good time to absorb chemistry learning materials. Students can also repeat or study the material again so that they understand better in the afternoon or evening. Thus, teachers can prepare teaching materials that have been adjusted to the time allocation so that learning is expected to run well and effectively

A new modern scheme for solving fractal–fractional differential equations based on deep feedforward neural network with multiple hidden layer

The recent development of knowledge in fractional calculus introduced an advanced superior operator known as fractal–fractional derivative (FFD). This operator combines memory effect and self-similar property that give better accurate representation of real world problems through fractal–fractional differential equations (FFDEs). However, the existence of fresh and modern numerical technique on solving FFDEs is still scarce. Originally invented for machine learning technique, artificial neural network (ANN) is cutting-edge scheme that have shown promising result in solving the fractional differential equations (FDEs). Thus, this research aims to extend the application of ANN to solve FFDE with power law kernel in Caputo sense (FFDEPC) by develop a vectorized algorithm based on deep feedforward neural network that consists of multiple hidden layer (DFNN-2H) with Adam optimization. During the initial stage of the method development, the basic framework on solving FFDEs is designed. To minimize the burden of computational time, the vectorized algorithm is constructed at the next stage for method to be performed efficiently. Several example have been tested to demonstrate the applicability and efficiency of the method. Comparison on exact solutions and some previous published method indicate that the proposed scheme have give good accuracy and low computational time.

Post-Covid Adaptation: Students' Mental Health and Higher Education System in Indonesia

The pandemic brought many changes, including for students. Various negative things experienced by students have an impact on their mental health. However, there are coping mechanisms that can bring positive changes to students' lives and help them survive the post-pandemic period. This research aimed to explore: the problems, level of stress, coping mechanisms carried out by students, and resilience level during the pandemic; the student's mental health situation during post-pandemic; and the recommendation for higher education (HE) institutions to support students' mental health. The research included 5018 students in bachelor's programs from 20 universities of APTIK members via quota sampling method on gender and class year (stage 1); and reports from students about their psychological symptoms during classes (n = 5 classes) and counseling (n = 10 cases) and literature review from explore 13 articles via Google scholar and Google search engine (stage 2). The study results show that students had many learning and social life challenges. Students who can develop positive coping with stress will be resilient and benefit from the experience during the pandemic, such as increased online learning skills, health awareness, and good time management. A positive coping strategy empowers the students to develop good mental health and survive during the pandemic, together with the support of the education system in higher education institutions. The institution should provide leadership, a good governance system, conducive teaching and learning system, and an appreciation for diversity and inclusivity to support students' mental health. The system should support the various changes experienced by students. With a good strategy and governance, there will be clarity and comfort so that it does not exacerbate the mental health problems encountered by many students. The impact is that students are more prepared and confident to connect with the industry world.

Adsorption performance of Cu-MoTe2 on SF6 decomposition products: A first-principles study

Detection of SF6 decomposition components is one of the best ways to diagnose early latent insulation faults in gas-insulated equipment, which can effectively prevent sudden accidents. Metal-doped MoTe2 is widely used as a gas sensor material in the field of real-time monitoring of gas decomposition components due to its excellent adsorption properties. In this paper, the adsorption performance and sensing characteristics of Cu-MoTe2 adsorption of SF6 decomposition components including SO2, H2S and SOF2 are calculated and analyzed based on first-principle. The results show that: the adsorption energies of Cu-MoTe2 for SO2, H2S and SOF2 are −1.196 eV, −0.881 eV, −0.024 eV, indicating that the adsorption for SO2 and H2S are chemisorption. However, the adsorption of SOF2 is physisorption. The same result is obtained for the calculation of the DOS. The work function results indicate that the potential of Cu-MoTe2 for detecting SO2 and H2S as a field effect sensor. The adsorbent material has a high sensitivity of 273546.56 and 5820652.37 for H2S and SO2 gases, and good desorption time for H2S adsorption at room temperature. It can be seen that Cu-MoTe2 has the potential of the application of chemical sensor materials.

Country Risk and Financial Stability: A Focus on Commercial Banks in Africa

This paper employs dynamic panel models to investigate the impact of country risk on the financial stability of banks in Africa. Using country risk and bank specific data for 10 African countries over the period of 2000 and 2021, the results reveal that African countries have a high country risk exposure. The country risk negatively and significantly affects African bank stability. The study findings suggest that compliance with at least Basel II capital requirements is needed to protect African banks from the negative effects of country risk on their stability in the short run. However, the adverse effects of prolonged country risk are mitigated by the compliance with higher Basel capital requirements in the long run. The results further show that an efficient legal and regulatory framework is essential to complement the capital buffer against country risk. Policies must be introduced to reduce country risk to enable African banks to adequately support the African economy in good and challenging times. Overall, country risk remains a threatening factor for bank stability, and consequently, banks need adequate capital to reduce the impact of country risk on bank stability in Africa.

X-ray timing detectors with HfO2 nanoparticle-loaded plastic scintillator and silicon avalanche photodiode

We successfully developed 20- and 40-wt% HfO2-nanoparticle-loaded plastic scintillators (Hf-PLSs), and subsequently, assembled X-ray timing scintillation detectors using the Hf-PLSs and silicon avalanche photodiodes (Si-APDs) as the photodetector. Two types of Si-APDs were examined for two different detectors. A proportional-mode APD (pAPD) exhibited a nanosecond response, but a relatively low internal gain of less than several hundred. By contrast, a Geiger-mode APD exhibited a high gain of 105−6, but its output pulse width was longer than several tens of nanoseconds; the pixelated device is called as SiPM. A pAPD (Hamamatsu Photonics S8664-4433, 3 mm in diameter) was used as the photodetector and was combined with 20 wt% Hf-PLS (∼3 mm cube) as the X-ray scintillation timing detector. A SiPM (Hamamatsu Photonics S13360-3025, 3 mm × 3 mm) was assembled with 40 wt% Hf-PLS (∼3 mm cube). The characteristics of the two types of scintillation timing detectors were evaluated using a 57.61-keV synchrotron X-ray beam to assess their applicability in nuclear resonant scattering experiments. Both the detectors were cooled down to −35 or −20 °C to reduce noise and obtain a higher APD gain. A good time resolution of (0.31 ± 0.04) ns (FWHM) was easily obtained with the SiPM detector using a large APD gain at −20 °C, although the time resolution of the pAPD detector finally reached (0.39 ± 0.04) ns (FWHM) at −35 °C owing to a small gain of 146. However, a maximum count rate of over 1.4 × 107 s−1 was observed owing to the fast response of the pAPD detector, whereas the SiPM detector exhibited a maximum count rate of 5.9 × 106 s−1 because of the long pulse tail of ∼30 ns.

‘We never get a space to just have a good time together’: indigenous LGBTIQSB+ young people carving out alternative viable lives

ABSTRACT In this paper, we begin to explore the connections between Indigenous LGBTIQSB+ young people’s intersecting identities and their everyday practices of constructing viable alternative lives in settler-colonial Australia. Drawing upon a series of in-depth narrative interviews and workshops with Indigenous LGBTIQSB+ young people that occurred across a four-year period (2019–2022), the paper discusses the core ways in which Indigenous LGBTIQSB+ young people are actively engaged in collective and individual processes of remaking their lifeworlds in efforts to realise viable socially inclusive and just communities of belonging and welcome. The article first briefly introduces key concepts and summarises the broader concerns of the young people involved in the research, as articulated during in-depth narrative interviews. The young people identify key areas they believe need to be seriously taken up for consideration in building alternative Indigenous LGBTIQSB+ futures. Young people collectively articulated these as enabling alternative futures of pleasure and desire, creating opportunities for gender, sex and sexuality education and, finally, collectively creating safe spaces for Indigenous LGBTIQSB+ gathering, welcoming and belonging.

Optimal Capacity Analysis Of Container Yard In Makassar New Port

Indonesia is an island nation whose two-thirds of its territory is water and is located in a strategic location because it is on a cross of world trade routes; therefore, the role of the port as a marine transportation system is crucial in supporting economic growth. The stacking field used to serve container cargo is one of the main port facilities to store containers originating from ships or going to ships. A buildup field is needed to prevent the risk of ship delay, which results in decreased loading and unloading production and the time of ships and goods being ported for a prolonged time. Makassar New Port is the largest seaport in the Eastern Region of Indonesia. Located in the Makassar Strait, Makassar New Port holds a leading role in the distribution of goods equipped with loading and unloading facilities to and from the ship to the receiving warehouse. This study aims to analyze the fertilization field's capacity for both the operator and the user. The result of this study obtained for the short-term optimum cost Container Yard in Makassar New Port is IDR 1.687.795.482.144 with the width of field dimension is 530.000 m2 . While for the Medium Term optimum cost is IDR 1.688.202.882.750 with the width of field dimension is 530.000 m2 and Long Term is IDR 1.689.520.940.921 with the field dimension is 535.000 m2.Times

Amorphous iron oxyhydroxides nano precursors used for Reactive Yellow 84 removal from aqueous solutions

In this research, we investigated the potential use of amorphous iron oxyhydroxides, ferrihydrite (FHY), for the removal of persistent pollutants from aqueous solutions. Ethylenediaminetetraacetic acid (EDTA) and ethylenediamine-N, N′-disuccinic acid (EDDS) were used as complexing agents during synthesis aiming to enhance the FHY properties. Synthesized materials were characterized by X-ray diffraction, SEM and TEM Microscopy, N2 sorption/desorption, and FT-IR Spectroscopy for their mineralogy, crystallinity, morphology and size, surface properties, and the organic content in their structure. The addition of chelating agents led to differences in nanoparticles morphology, amorphic degree, and surface properties. Reactive Yellow 84 dye was chosen as a representative refractory pollutant and laboratory-scale adsorption studies were conducted at varying dye concentrations. Ca. 100 % RY 84 dye removal efficiency was achieved within one hour at dye concentrations of 5–10 mg/L for an adsorbent dosage of 1 mg/L FHY. Adsorption kinetics and isothermal studies were considered, the uptake capacity was calculated for each nanomaterial and empiric mechanistic information was derived. The results showed that ferrihydrite exhibits the best performance, with a maximum uptake capacity of 40.73 mg Reactive Yellow 84 dye per gram adsorbent followed by FHY_EDTA and FHY_EDDS (up to 35.86 mg/g). Coupling the adsorption with photodegradation processes led to a significant increase in removal efficiencies of persistent RY 84 from polluted aqueous solution, in good timing, suggesting a feasible alternative at sites where dye concentration in effluents is elevated.

Quality Evaluation Of Different Commercial Shampoo Brands Made In Nepal

Background: Shampoo is one of the most popular cosmetic items for washing the hair and scalp. It is necessary to evaluate shampoo in order to understand its performance, quality, and effectiveness, as well as to ensure compliance with the standards of many journal articles. Objective: The purpose of the research study was to evaluate the quality of four commercial and two medicinal shampoo brands made in Nepal. Method: A cross-sectional, descriptive study was carried out in order to evaluate label information, microbiological quality, and physiochemical parameters such as (pH, density, viscosity, surface tension, foaming ability & stability, detergency power, wetting time etc. Furthermore, a UV-visible spectrophotometer was used to measure the percentage of assay of medicated sample. Result: When compared to secondary data from journals, the study found that not all shampoos met specifications. It was found that only S5 of the six samples tested positive for microbial growth and exceeded the limit. Except for S5, the pH ranged between 5-7.The surface tension of all samples meets the specifications. S1-S4 had normal detergency power, however the medicated sample had low detergency power. All demonstrated good wetting time and dirt dispersion. The percentage of solid content in S1-S2 was very low. The assay percentage was within the prescribed range for medicated sample. Conclusion: When compared to a standard journal, the study found that certain parameters were within range while some were out of range.
