Various attempts have been made for the green synthesis of metal oxide nanoparticles, revealing the significance of plant extracts in reducing metal sources to nanoparticles and applications in various scientific domains. Azadirachta indica (family Meliaceae) is an evergreen tree that contains several phytochemicals within its leaves. This study aimed to perform the green synthesis of selenium nanoparticles (SeNPs) from Azadirachta indica leaves extract. In respective research attempts, NPs were evaluated for applications of anthelminthic and cytotoxic activities. Transmission electron microscopy analysis revealed the spherical morphology and size ranged from 62.1 to 77.6 nm of Bio-SeNPs. Phenolics and flavonoids were determined to be 0.83 ± 0.05 µg/g and 7.37 ± 0.32 µg/g, respectively, and antioxidant activity was 23.93 ± 2.05. For anthelminthic activity, the model earthworm, Eisenia fetida, was tested. Bio-SeNPs (5 mg/ml) have the lowest time for paralysis and death of earthworms (33.68 ± 1.13 and 50.10 ± 2.21 min, respectively). Moreover, histological examinations showed shrinkage of the worm body among treated groups in comparison to control group. In addition, IC50 of Bio-SeNPs was obtained at 127.212 µg/ml for the HCT116, 263.430 for MDA-MB-231, and 330.456 µg/ml for HUH7 cell lines. Our results suggest Bio-SeNPs possessed anthelmintic and biocompatibility activities.

Bu çalışmada Çam Keseböceği [Thaumetopoea pityocampa (Den.&Schiff.)’nin (Lep.: Notodontidae)]’nin önemli yumurta parazitoiti olan Ooencyrtus pityocampae (Mercet) (Hym.: Encyrtidae)’nın Graphosoma lineatum (L.) (Het.: Pentatomidae) yumurtalarındaki etkinliği ve parazitlenme süresinin etkisi ele alınmış olup çalışmalar 25±1°C sıcaklık ve %65±5 neme ayarlı iklim odasında yürütülmüştür. Değişik sürelerde (24, 48 ve 72 saat) parazitlenmeye bırakılan yumurtalarda parazitoitin bir dölünü tamamladığı süre (gün) ve parazitlenme oranları (%) belirlenmiştir. O.pityocampae ve G.lineatum’un gelişimlerini sırasıyla 15-19 ve 7-8 günde tamamladıkları saptanmıştır. Değişik sürelerde gerçekleşen parazitlenme oranları arasında önemli bir fark bulunmamıştır. Parazitoit gelişme süreleri bakımından en erken parazitoit çıkışlarının (14,97±0,45 gün) 48 saat süreyle parazitlenmeye bırakılanlarda gerçekleştiği tespit edilmiştir. O.pityocampae’nın G.lineatum yumurtaları üzerinde yetiştirilmesi düşünüldüğünde; parazitlenme oranının yüksek olması ve nispeten kısa sürede gelişmesi bakımından 48 saatlik sürenin uygun olabileceği kanısına varılmıştır.

Published: May 2023

Leprosy, also called Morbus Hansen, is a contagious skin disease caused by the bacterium Mycobacterium Leprae. It takes 2–5 years for the disease to show up, and it takes 2–3 weeks for the cells to divide. Leprosy reaction is a sudden event that happens during the long-term course of the disease. It causes skin sores to become very red and swollen. This disease can show up before, during, or after treatment for leprosy, and it can happen to 30–50% of people with leprosy. Reactions to leprosy happen when both cellular and humoral immune responses go wrong. Type 2 or Eritema Nodosum Leprosum (ENL) reactions have a clinical picture of the appearance of nodules in the skin. This reaction occurs in leprosy patients with very large numbers of bacteria, namely the multibacillary type. In contrast to the reversal reaction, the humoral immune response plays an important role in the pathogenesis of ENL. Large amounts of bacterial antigen concentrations in tissues will increase IgM and IgG titers in multibacillary leprosy patients. Th2 cell activation will stimulate the production of IL-4 and IL-10, thereby increasing the humoral immune response and increasing the production of B lymphocytes. The goals of the treatment are to control the inflammation, ease the pain, and stop new cases from happening. In weak cases of ENL, the best way to treat it is to rest and take anti-inflammatory drugs. Most of the time, people take aspirin, which is an anti-inflammatory drug. Other drugs have also been tried, including nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, oral zinc, pentoxifylline, and chloroquine. But each of the current treatment options has its own downsides and limitations, and the best one must be carefully chosen for each case.

Published: May 2023

The air permeability of fabrics is one of the most important factors to be considered in making comfortable clothing for consumers. It helps to transport moisture in the form of vapours from the inner skin to the outer environment. This study aims at determining the rate of airflow through the prepared knitted fabrics after various washing intervals. Circular knitted fabrics with 100% cotton and a blend of cotton and polyester having a ratio of 70% / 30% were made by setting different construction parameters. Prepared fabrics were evaluated for their air permeability by following the ASTM D737-1996 test procedure. Then these fabrics were laundered with standard procedure and evaluated after various intervals. It was concluded from the obtained results that construction parameters such as kind of polymer, loop length, hairiness, yarn count, number and size of pores and their distribution play a major role in determining the air permeability of knitted fabrics. Moreover, an increase in washing cycles also reduces the airflow through the fabric.

Published: May 2023

In order to improve the sharp return characteristics of the flutter mechanism, and then increase the downward power of the flutter aircraft, reduce the drag of the wing upward, and increase the flight efficiency, this paper designs a flutter drive mechanism with sharp return characteristics based on the eccentric crank slider flutter structure. Firstly, the kinematic model of the eccentric crank slider mechanism is established through motion analysis, and then the simulation model of the flutter mechanism is established in SOLIDWORKS to simulate its motion and verify its theoretical analysis. The results show that the designed flutter mechanism has an upper limit angle of 17°, a lower limit angle of -34°, and a travel speed ratio of 1.35, which are consistent with the flight parameters of the selected bionic bird, so it has good aerodynamic performance. And the kinematic parameters obtained from the simulation are consistent with the theoretical calculation, which verifies the correctness of the theoretical calculation.

Authors:   Haaga-Helia University of Applied Sciences, 00520 Helsinki, Finland, Toivonen Annette
Published: May 2023

The recent emergence of the tourism sector in the New Space industry, that provides commercial alternatives to publicly funded “Old Space” operations, fits within other societal trends enhanced by technological developments. There are several possible forms of space tourism and, within each, a growing number of competing space tourism ventures will emerge over time. However, whilst the New Space tourism industry is to provide a tourist with new travel experiences, international climate reports urge for more sustainable operations in all global industries. Therefore, climate change preventing solutions must be sought to decrease any unnecessary impacts caused by this new adventure sector of tourism from the beginning. As there are different variables to consider in the formation of future New Space tourism operations and strategies, this paper also illustrates a new framework of “Societal ethics in space tourism”, involving concepts attached to New Space tourism sustainability; environmental actions, global space regulations, cyberspace tourism, and Generation Z values.

It is possible for a natural catastrophe to cause harm to numerous industrial facilities in the same region simultaneously. The natural catastrophe's Natech events may then affect the industrial facilities that are located nearby, so creating a coupling risk. The evaluation of the danger of Natech events coupling is conducted using the technique of multi-criteria decision-making (MCDM) methodology in this investigation. Additionally, the concept of spherical fuzzy is presented as a means of resolving the issue of ambiguity associated with the Natech coupling risk. The Natech Coupling Hazard Index is designed to include both tangible and operational resources in its calculations. The idea of an equal population is being floated as a means of contrasting the dangers presented by physical facilities with those posed by functional amenities. The spherical fuzzy set is an effective method for coping with ambiguity since it presents a broader decision-making region and identifies reluctance. under this paper, a fuzzy MDCM technique using spherical fuzzy AHP is proposed as a solution to the challenge of managing the selection of process mining methods under settings that are unclear and vague. The AHP method is used to compute the weights of criteria and shows the rank and order of alternatives. The application is performed in steps of the spherical fuzzy AHP method.

Tropical legumes are used to prepare mixed silages to enrich the crude protein (CP) content. In This context, objective of this study was to evaluate the dynamics of fermentation and quality of maize silage with different levels of Pigeon pea. The experimental design was entirely randomized, with four repetitions. The treatments comprised maize silages with six levels of added Pigeon pea (0, 20, 40, 60, 80, and 100%), calculated based on natural matter. The maize hybrid and Pigeon pea varieties used were B 2800 PWU and Cajanus cajan cv. BRS Mandarin, respectively. For the silage, the maize and Pigeon pea were harvested when they reached 335.7 g kg-1 dry matter (DM) and 281.3 g kg-1 DM, respectively. The results revealed that the added of up to 40% Pigeon pea in maize silages promote nutritive increment without compromising their fermentative profile of the silage. Exclusive Pigeon pea silage (100%) undergoes fermentative losses that compromise the silage quality. Therefore, mixed silages of maize with Pigeon pea, with appropriate levels of addition, are a viable alternative to increase the nutritive value of silages, mainly the CP content, contributing to reducing the cost of acquisition of protein salts.
Refined horoball counting and conformal measure for Kleinian group actions
Authors: Fraser Jonathan M. , Stuart Liam
Published: May 2023

Parabolic fixed points form a countable dense subset of the limit set of a non-elementary geometrically finite Kleinian group with at least one parabolic element. Given such a group, one may associate a standard set of pairwise disjoint horoballs, each tangent to the boundary at a parabolic fixed point. The diameter of such a horoball can be thought of as the 'inverse cost' of approximating an arbitrary point in the limit set by the associated parabolic point. A result of Stratmann and Velani allows one to count horoballs of a given size and, roughly speaking, for small \(r>0\) there are \(r^{-\delta}\) many horoballs of size approximately \(r\), where \(\delta\) is the Poincaré exponent of the group. We investigate localisations of this result, where we seek to count horoballs of size approximately \(r\) inside a given ball \(B(z,R)\). Roughly speaking, if \(r \lesssim R^2\), then we obtain an analogue of the Stratmann-Velani result (normalised by the Patterson-Sullivan measure of \(B(z,R)\)). However, for larger values of \(r\), the count depends in a subtle way on \(z\).

 

Our counting results have several applications, especially to the geometry of conformal measures supported on the limit set. For example, we compute or estimate several 'fractal dimensions' of certain \(s\)-conformal measures for \(s>\delta\) and use this to examine continuity properties of \(s\)-conformal measures at \(s=\delta\).

CrossFit is a high-intensity exercise program that has gained popularity over the past few decades. CrossFit combines movements from Olympic weight lifting, gymnastics, powerlifting, and high-intensity interval training. As CrossFit continues to expand, knowledge of the associated orthopaedic injuries to aid providers in diagnosis, treatment, and prevention will be increasingly important. The most common CrossFit injuries occur in the shoulder (25% of all injuries), spine (14%), and knee (13%). Male athletes are markedly more likely to experience injuries than female athletes, and injuries occur markedly less when there is supervised coaching of the athletes. The most common causes of injury in CrossFit include improper form and exacerbation of a prior injury. The purpose of this article was to review the literature to aid clinicians in identifying and treating common orthopaedic injuries in CrossFit athletes. Understanding the injury patterns, treatment, and prevention options is important for a successful recovery and return to sport.

Individuals diagnosed with cardiac diseases often experience poor mental health outcomes. However, grit, social support and internal locus of control can provide protective effects against poor mental health in patients diagnosed with cardiovascular diseases. The purpose of the present study was to assess the predictive and protective role of grit, internal locus of control and social support with regard to mental health of cardiac patients. A total of 250 cardiac patients had been sampled comprising 130 males and 120 females in the age range of 30 to 70 years selected through purposive sampling. Data collection was done using Rotter’s Locus of Control Scale, Multidimensional Scale of Perceived Social Support, Duckworth Grit Scale and DASS-21. Data analysis was done using Pearson correlation and regression analyses using dummy coding. Results showed that among cardiac patients, being a male in the age range of 30 to 45 years of age, being married, having higher levels of education, higher scores on grit with an internal locus of control is associated with improved mental health. It is thus concluded that having an internal locus of control, higher levels of social support and being gritty is associated with improved mental health outcomes in cardiac patients.

Proton pump inhibitors (PPIs) are widely used for the treatment of acid-related gastrointestinal disorders. However, their overuse or inappropriate prescription can lead to adverse effects, increased healthcare costs, and development of antibiotic-resistant infections. Objectives: To ascertain whether the Omeprazole (Risek®)-PPIs prescription patterns by practitioners in the inpatient and outpatient departments of various healthcare facilities in Pakistan are in compliance with the therapeutic indications and to evaluate the safety profile associated with each therapeutic indication. Methods: A cross-sectional multicenter study was conducted for 4 months at various healthcare facilities inpatient and outpatient departments. A total of 1384 patients ≥ 18 years prescribed Omeprazole (Risek®) were enrolled while pregnant or lactating women, patients with chronic diarrhea, those with a history of Omeprazole allergic reaction, and with diagnosed malignancy of the GI tract were excluded. The drug use was determined based on the prescribed frequency, dosage, and duration of therapy with respect to each indication. Results: Of the total, 29.8% were already taking oral PPI or Histamine H2-Receptor Antagonists. The common indication for Omeprazole (Risek®) was Gastroesophageal Reflux Disease (GERD), followed by peptic ulcer. Mostly the drug was infused/injected in 40 mg dosage, once daily and for five days among 76.6% and 41.8%, respectively. Around 13.3% of patients experienced mild adverse events like flatulence, fever, vomiting, abdominal pain, constipation, diarrhea, nausea, rash, etc. Most off-label uses were observed in GERD concerning the duration of therapy (55.9%), prescribed frequency (19.7%), and dosage (5.9%). The Omeprazole (Risek®) treatment was also prescribed for stress ulcer prophylaxis and upper GI bleeding against the treatment protocol for the particular therapeutic indication. The adverse events were most frequent among patients with GERD, followed by NSAID-induced ulcers. Conclusions: This study provides clinical evidence on the Omeprazole (Risek®) use in concordance with the product label, in both inpatient and outpatient departments of Pakistan for various therapeutic indications.

The isthmus-dependent atrial flutter can be effectively treated with Radiofrequency (RF) catheter ablation. Objectives: To compare the ICE guided versus non-ICE radiofrequency catheter ablation of Cavo tricuspid isthmus dependent atrial flutter. Methods: A cross-sectional study was carried out on 40 patient’s atrial flutter data in the Cardiac Electrophysiology Department, Hayatabad medical Complex Peshawar, Pakistan from August 2017 to August 2022. Patients were categorized into two groups: Group-I (ICE-guided RF catheter ablation) and Group-II (non-ICE RF catheter ablation). The standard protocol of ablation was followed using 40-50 watts power at temperature 60oC.  In the case of an irrigated cooled tip catheter, the flow was limited to 30 mL/hour and the power was limited to 30 watts. Results: The overall mean ablation and flouro time was 9.44 ± 6.93 minutes and 20.64 ± 9.77 minutes respectively. The frequency of patients in Group-I and Group-II was 29 (72.5%) and 11 (27.5%) respectively. Out of the total patients, about 8 (20%) patients had shown failed status in terms of procedure success, out of which 5 (62.5%) were from Group-II. Compared to non-ICE guided procedure, the ICE guided procedure had lesser flouro and ablation time with higher rate of success and lower complications and recurrence. Conclusions: The present study observed that intracardiac echocardiography (ICE) can effectively disclose the Cavo tricuspid isthmus and guide ablation anatomy. Additionally, ICE guided radiofrequency catheter ablation had higher success rate, less flouro and ablation time, and lower complications than non-ICE guided radiofrequency catheter ablation.

ABSTRACT

When looking at companies that have adopted TQM as part of their corporate strategic planning, DEWA stands out as one of the most successful. Examining the specifics of DEWA's strategy and the rules it follows to be an innovative corporation is essential to understand how the company got successful. This research analyzes quality management and discusses various topics relevant to Excellence and TQM. Subsequently, how DEWA practices and implements overall quality management, with an emphasis on multiple divisions, where several patent applications have been filled. The results indicate that DEWA systematically assesses its quality management concepts highlighting TQM and the BEM they use (EFQM) to ensure they are in line with the strategy of the business and the global innovation index. Due to organization’s high level of implementation and focus on quality, no major gaps were observed. However, there is always a need to maintain forward momentum, in which it requires the company's concepts to be in sync with all these principles (TQM & BEM) along with ISO, and risk management.

Depending on outsourcing software services is increasing so it became important to understand the idea fully and know how to manage it. This paper aims to identify and prioritize software outsourcing problems facing organizations in the UAE and to propose a solution for keeping these services under control. Thus, to meet project’s objectives and answer research questions, qualitative research approach was used to cover “what” and “how” questions of the paper. The research’s data were collected through employing semi-structured interviews done with IT managers, business managers and vendors from three organizations and three service providers so a total of nine interviews were conducted. The results indicated that organizations are outsourcing their software services because of some common reasons and in the same time they are facing issues with their service providers. The discussion revealed shared problems among participants and prioritize them according to their repetition. The value and originality of this research comes from revealing the set of problems facing each one of three studied groups: IT manager, business manager and vendors to provide a clear image of the reality of software outsourcing in the UAE and to help future researches about the topic. Based on findings and relevant literature a set of practical implications were suggested to control software outsourcing services and eliminate their risks on clients and vendors.
Effect of one hour kick boxing exercise on lipid profile
Authors: N Shilpa , Jangam Swati , Singode Chetana
Published: May 2023

Background: Physical inactivity and a sedentary lifestyle are contributory factors for increased risk of obesity, hypertension, hyperlipidemia, and related complications, namely cardiovascular diseases. Cardiovascular diseases, namely atherosclerosis, myocardial infarction, and stroke are very common cardiovascular complications of uncontrolled hyperlipidemia. On the other hand, regular physical exercise decreases weight and body fat deposits. Regular exercise also increases high-density lipoprotein (HDL) cholesterol and therefore decreases the risk of atherosclerosis. Different studies on the effects of acute one session of exercise on lipid profile have shown variable results. Our study aimed to study effects of 1 h intensive exercise on the lipid profile of females performing regular exercise for 1 year. The lipid profile study included total cholesterol (TC), triglycerides (TG), low-density cholesterol low-density lipoprotein (LDL), Very low-density lipoproteins (VLDL), and HDL cholesterol.

Aims and Objectives: (1) To compare blood levels of TC and TG before exercise and immediately after 1 h exercise (2) To compare blood levels of HDL, LDL, and VLDL before exercise and immediately after 1 h exercise.

Materials and Methods: The study included 30 females in the age group of 20–50 years. Exercise included warming up for 10 min, followed by intense exercise for 40 min and then the last 10 min of relaxing exercise. Kickboxing exercise included upper limb and lower limb movements mimicking punching. Blood samples were collected from the antecubital vein with all aseptic precautions. Two blood samples were collected. First sample before the exercise and the second sample was immediately after 1 h of intense exercise. 2 mL blood was collected in a container without any anticoagulant. A lipid profile study for TC, TG, HDL, LDL, and VLDL was done using the automated biochemical analyzer.

Results: In our study, the post exercise samples showed a significant increase in HDL levels and significantly decreased levels of TC, TG, LDL and VLDL.

Conclusion: The effects of one session of intense exercise on lipid profile in females are beneficial as HDL levels are increased and TG, LDL and VLDL levels are decreased. These results are encouraging and useful for promoting females for regular exercise. This is very important for perimenopausal and postmenopausal females, as after menopause females are more prone for hypercholesterolemia due to a lack of estrogen.

Published: May 2023

The paper analyses thermal sensations, preferences and acceptability as well as humidity sensations of students in the intelligent building "Energis" of the Kielce University of Technology (Poland). The tests were performed in 8 lecture rooms, during which the volunteers filled in the anonymous questionnaires (with 3 to 7 possible answers for each question) and – simultaneously – physical air parameters were measured with Testo 400 microclimate meter. The study aimed to determine if the intelligent building provides proper indoor environment conditions during the heating season and to assess the accuracy of the standard methodology for thermal comfort determination. Experimental analysis of thermal and humidity sensations revealed that a share of the respondents critically assessed the indoor environment: 17% regarding temperature and 30% regarding humidity. Moreover, the standard methodology for thermal comfort calculations proved overwhelmingly inaccurate compared to the experimental data (with the results for 6 rooms being beyond the 50% error range). Since smart buildings are still not very common in Central Europe, the experimental data obtained in the study can be valuable both from the scientific but also practical point of view – providing useful data for building engineers and designers.

This research focused on teachers' and students' feedback on the application of Microsoft Sway in creating interactive presentations in an English-speaking Country Study course at a public university in Vietnam. Forty-five third-year English-major students were divided into five groups and required to create online presentations on different aspects of life in English-speaking countries, using specific templates in Microsoft Sway and incorporating various online and offline multimedia sources. The study was conducted through focus-group discussions with students and semi-structured interviews with teachers. Results showed positive feedback from students on improving their academic performance and language skills, citing benefits such as saving time with the tool's effortless design and easy access to a variety of useful reference sources. Teachers' interviews revealed improvement in students' reading, writing, and critical thinking skills during the process of creating content for the interactive presentations. However, students encountered difficulties searching, filtering relevant information on the web, and creating outlines for presentations. The study has practical implications for teachers and researchers looking to apply new online learning and teaching tools in similar educational contexts.
