Authors: Samireddypalle Yugandhar , Muhammed Hira , Chanu Sairem Mangolnganbi , Poongodi R
Published: March 2024

Dermoid cysts are the most frequent ovarian tumours among women of reproductive age, constituting a notable 20% of all adult ovarian tumours. They are typically lined by stratified squamous epithelium and contain dermal and epidermal elements. During pregnancy, dermoid cysts are more likely to lead to infection, rupture and torsion. A 23-year-old multigravida (G2P1L1) female at 36 weeks of gestation presented with complaints of left lumbar pain persisting for one day, unrelieved by medication. Ultrasound (USG)revealed a multiloculated septated cystic lesion in the left lumbar region adjacent to the gravid uterus, just anteroinferior to the left kidney. Magnetic Resonance Imaging (MRI) showed a predominantly fat-density multiloculated cystic lesion with twisting of the pedicle. An emergency laparotomy was performed, and the left ovarian cyst was removed, revealing patchy discolored areas of gangrene, and a live healthy foetus was delivered. While torsion of an ovarian cyst is a well-known complication, its presentation during pregnancy is rare. Due to the variable symptoms of ovarian torsion, the clinical presentation can be quite confusing. Therefore, both the obstetrician and radiologist should have a lower threshold for clinical suspicion of torsion in pregnancy, enabling prompt diagnosis and management of such cases to prevent both maternal and foetal mortality.

Unemployment is one of the most important problems affecting people in all countries. It affects the functioning of entire economies, industries, and enterprises; it also reduces the level and quality of people’s lives. The dynamic changes that are taking place in the labor market are forcing entrepreneurs to adopt a flexible approach to labor market resources – that is, employees – and also to choose appropriate forms of human capital management. This may lead to a reduction in unemployment in the market. Consequently, tackling unemployment is one of the important challenges facing the European Union, especially on its way to achieving sustainable development goals. High levels of unemployment could significantly hamper the achievement of the Agenda 2030 employment targets (SDG8), leading to poverty, social and economic inequality, and social instability. Therefore, the subject of this study is unemployment in EU countries; the main objective is to examine unemployment levels across EU member states. The deliberations and analysis are carried out in the context of the Agenda 2030 Goal 8 (SDG 8) for sustainable development. Taking into account the different degrees of implementation of SDG8 by individual Member States, and thus the different results in this respect, the study finds differences and similarities among the surveyed Member States in terms of types and levels of unemployment. The research is based on Eurostat data for 2022, and uses multidimensional comparative analysis methods such as cluster analysis and linear ordering. A review of selected sources on international and European law focuses on employment policy standards, including the problem of unemployment; this serves as a background for the analyses. The considerations are embedded in the concept of sustainable development, which influences the functioning of entire economies, but also in the processes of enterprise management. Based on the literature and the results of the analyses, it is concluded that levels of unemployment vary greatly in the analyzed countries. The best conditions for availability and accessibility of work are found in the Czech Republic and Malta; the worst are in Spain and Greece, where unemployment is very high.

Published: March 2024

An important feature of contemporary armed conflicts is the large-scale use of air attack. The events of the last two years have made many experts realize that the present air safety environment is increasingly uncertain, complex, and difficult to forecast. It is therefore justified to present current issues related to anti-missile defense – which, in the authors’ opinion, is crucial for the functioning of NATO border states.The aim of this article is to describe cooperation in the framework of anti-missile defense in the Euro-Atlantic area, which is characterized by a dynamic process of transformation, including ambitions among some countries to dominate in this dimension.This study uses document research and quantitative and qualitative analysis. It reviews the scientific literature on the complex issue of cooperation in the field of missile defense, and uses publicly available information provided by interested institutions. The results show that this cooperation is not a new phenomenon, but it currently requires organized political and military actions from states, including their armed forces.

Published: March 2024

The aim of the theoretical analysis is to define the connections and dependencies between the rationality of decisions made and personality determinants, in this case the construct of being good to oneself. The achievement of the intended goals was based on a systematic review of the literature on the subject, referring to the results of foreign and domestic empirical research, mainly in the field of social sciences and philosophy. The implementation of the theoretical goal complements the research gap that comes from the fact of inflation in the field of self-compassion and praxeological leadership, and their mutual functional connections. The practical usefulness of the conducted analysis is an interesting and solid contribution to asking research questions and planning further research on the participation of personality factors in decision-making processes in leadership.As a result of the critical analysis, a concept of praxeological leadership was presented, which highlighted the role and importance of self-compassion, indicating the positive and negative aspects of the analyzed correlation in the decision-making process in management and leadership.

Published: March 2024

Funding information: International Visegrad Fund Grant Number IVF 22230264. This article presents the results of a survey conducted in the first half of 2023. A total of 812 questionnaires were obtained from current and potential consumers (individual and B2B) in the Visegrad countries. The survey’s goal was to find out how consumers perceive and evaluate the quality and pro-ecological factors/challenges of the products of the electrical machinery industry, in the context of their declared personal purchases. Among other things, it sought to establish the actions consumers expect from manufacturers if they want to increase the market share of good-quality and environmentally friendly products. Improvements to the quality of products, with reductions in their negative environmental impact throughout their life cycle, were noticed most in Hungary and Poland. In all countries surveyed, consumers agreed most strongly with the statement that to increase the market share of good quality and environmentally friendly products, producers should enable recycling, disposal, and so on, and improve the availability of information.

Authors: LEW Grzegorz , BOCHENEK Magdalena
Published: March 2024

In any enterprise, the customer plays a key role as the main “provider” of revenue. The profitability of a particular enterprise depends on appropriate customer relations. Profitable customer relations are crucial for conducting and continuing business. The purpose of this article is to present the author’s concept of customer cost accounting, which will effectively support decision-making in optimizing customer relations. The main basis for the conceptual work on the customer account is research conducted on 178 companies, the results of which clearly indicated the need to analyze the profitability of customer relationships. The research used a survey questionnaire and statistical tools. First, basic statistical measures were applied. Non-parametric tests were used to evaluate the relationships between variables: Pearson’s chi-square test, Spearman’s rank correlation, and the Kruskal-Wallis ANOVA test. Through the research, three theses were falsified and confirmed.

Published: March 2024

This article aims to analyze living conditions in Poland and Lithuania after theCOVID-19 pandemic, using Eurostat data for seven chosen indicators. The dynamics indices were used to examine the changes in the analyzed indicators over the studied period. Stepwise regression method was used to investigate the impact of the highlighted variables on GDP per capita. The indices allowed us to interpret whether there was a decrease or an increase in the variables throughout the analyzed period, as well as to compare the results for individual years. The results should help the authorities of the analyzed EU countries to make decisions regarding the objectives of the 2030 Agenda. The research shows that the GDP per capita variable is influenced by the inflation rate, people’s inability to “make ends meet,” and the share of people living in under-occupied dwellings. The dynamics of people at risk of poverty in Lithuania have increased by 1.5% since 2013. Based on the results for both Lithuania and Poland, the implementation of the main principles of the sustainable development goals, including the elimination of poverty and hunger, may be at risk. If the governments of these countries do not take decisive steps, the achievement of the SDGs by 2030 may be threatened.

This article is based on empirical research conducted in SMEs in several countries: the Czech Republic, Slovakia, Lithuania, and Poland. The basis for empirical recognition was the assumption that it is possible to develop a positive attitude among employees towards work. The research problem concerned the search for the characteristics of the organizational environments of SMEs in the context of achieving job satisfaction. The research question was, “How and with what mechanisms can the positive attitudes of employees towards their work be strengthened?” To measure employees’ attitudes toward work, quantitative research was carried out using a questionnaire on a sample of 590 respondents. The key dimensions of satisfaction in the workplace were analyzed; these included the quality of management processes, social communication, interpersonal relations, remuneration or self-realization, and fulfillment of competence potential. Summing up the results of the empirical research, it is worth emphasizing that SME employees noticed many different factors affecting, to a greater or lesser extent, their perceptions of professional satisfaction. Among these, they most often mentioned detailed elements of the general context of achieving satisfaction in relation to, for example, individual abilities and skills, interpersonal relationships, communication processes, and reward and motivation systems.

Gamification, which uses the mechanisms of games to acquire knowledge and various types of skills to build people’s involvement in a specific activity, is playing an increasingly important role. This study aims to emphasize the importance of gamification in the management process, with particular attention to its use in the educational process. It employs a critical literature review, observation, and case studies, containing an analysis of active gamification-based methods used in teaching management (organization and management) and production management. On the basis of the pilot program MANAGER BOB IN, the game used during the production management course, and the experiences of the authors of the study in creating various games, it can be concluded that it is necessary to allocate more time during organizational classes to explain the principles and benefits of participation in gamification, and to extend the time for the implementation of selected challenges. Information feedback is also important, as is the use of various technical solutions that affect the attractiveness of games and the entire educational process.

Published: March 2024

One of the biggest challenges for modern metropolises is the problem of public transportation. Barriers to the development of urban transport, the expansion of private vehicles, congestion of beehives, traffic jams, parking problems, and the negative impacts of transport on the environment are causing an increase in interest in shared micromobility. Electric scooters are one of these innovative solutions. This article aims to construct a model for the acceptance of electric scooters among students. The authors employed the technology acceptance model, and used the SmartPLS 4. Program to reconstruct the model. The basis of the model was a CAWI survey on a sample of 442 students. On this basis, the study verified the hypotheses on the relationships between the factors influencing the acceptance of electric scooters: demographic characteristics, perceived usefulness, ease of use, attitudes towards this solution, and behavioral intentions.

Published: March 2024

Among the effects of COVID-19 are taste and smell disorders, which have occurred in a significant number of sick people. It is believed that the impairment of these senses may be long term. The aim of our research was to investigate the impact of COVID-19 disease on the ability to recognize tastes among students at the Rzeszów University of Technology. The research was conducted on a sample of students who declared that they had or had not suffered from COVID-19. The assessment of the ability to recognize flavors – that is, taste color blindness – was carried out based on the methodology recommended by the Polish Committee for Standardization [PN ISO3972]. The research, which involved 68 women and 74 men, was carried out in a laboratory adapted for this purpose, meeting the requirements specified in the standard [PN ISO 8589]. The tests took place in the morning (9 a.m.–12 p.m.). Taste recognition ability was assessed using a set of aqueous solutions of citric acid (0.43 g/L), sucrose (5.76 g/L), sodium chloride (1.19 g/L) and caffeine (0.195 g/L). The collected questionnaires were based on a standard approach to food quality analysis, and the data obtained were analyzed in the Statistica 13.3 program. It was observed that, in the studied group of students, the percentage of people who declared COVID-19 disease was high (69%). In this group, the majority of respondents (51%) described the course of the disease as mild. Among the respondents, 63.3% indicated a loss of taste, while slightly more (69.4%) declared a loss of smell. The analysis of data regarding the ability to correctly recognize individual tastes indicates that gender influenced the ability to recognize sweet and bitter tastes. Statistically, significantly more men misidentified these flavors. The impact of COVID-19 infection on the ability to identify the analyzed flavors was moderate and was confirmed only for salty and bitter tastes. Therefore, the ability to perceive important qualitative factors of food products was impaired.
EXPLORING THE EFFECTS OF OIL PRICES ON ROAD FREIGHT IN POLAND AMIDST COVID-19 AND RUSSO-UKRAINIAN WAR

Published: March 2024

Destructive market forces are multiplying as the world faces the worst global energy crisis in history. The continuing economic downturn and fluctuating oil prices, triggered by OPEC+’s plan to reduce supply, are slowing down global oil demand. In this respect, the situation in the transport services market is changing. Changes in the price of oil are indirectly influencing the formation of wholesale diesel prices; consequently, road freight should also change. However, are these changes correlative and do oil price fluctuations directly affect freight rate changes? This article aims to investigate the correlation between fluctuations in oil prices on world markets and their impact on wholesale diesel prices and, thus, the development of net road freight in Poland. In the study, the authors developed a model called “fuel adjustment,” containing the fluctuations in wholesale diesel prices, which were taken into account in determining the average deviation in the road freight level over the analyzed period. In this way, it became possible to determine the amount of road freight and its fluctuations depending on the development of oil prices on world markets. The results of the study confirm that there is a strong and positive relationship between the analyzed variables. When the prices of crude oil on world markets fall, this should be followed by reductions in diesel prices in individual countries, including Poland. Consequently, the amount of road freight should also have a downward trend. Will this happen?

This present study was conducted in Jharkhand, India, during 2021-2022, aimed to assess the socio-personal, and communication characteristics of trainee and non-trainee of Deoghar, Dumka, and Giridih districts of Jharkhand. The Data were collected from 200 trainee and 200 non-trainee respondents using stratified random sampling and analysed using appropriate statistical tests. The results indicate that the majority of farmers had limited education, with most living in semi-cemented or cemented houses. Marginal farmers were predominant in both groups, with low annual income levels. Trainee respondents exhibited higher levels of innovativeness and leadership ability compared to non-trainees, suggesting a positive impact of training programs. However, both groups showed a need for improvement in scientific orientation. The study underscores the importance of targeted interventions to improve education, infrastructure, and income levels among farmers in Jharkhand. Training programs should focus on enhancing not only technical skills but also innovativeness, leadership, and scientific orientation to enhance agricultural productivity and livelihoods in the region. The major sources of communication where radio ,television newspaper, magazine etc.

Published: March 2024

This study assessed the relationship between airport departure non-processing service performance and international tourists' satisfaction at Kilimanjaro International Airport. A survey research design and quantitative approaches with stratified sampling and a 162 sample size were adopted. Data collection was done through closed-ended questionnaires. The questionnaires were distributed to tourists and picked after being filled up.  Respondents’ responses were based on a five-point Likert Scale. Data analysis was done using IBM SPSS statistics version 21 and Partial Least Squares – Structural Equation Modelling using SmartPLS 3 software with the help of SmartPLS3 software. The study showed that airport departure facilities were directly and significantly associated with international tourists' satisfaction. This implies that the relationship exists in real life, and any effort to disregard the assessment of these facilities may disturb tourists' satisfaction and lead to untrustworthiness. Moreover, airport departure accessibility and departure retail areas showed an insignificant association with international tourists' satisfaction, implying that no relationship exists in real life. The study recommends that indicators for the constructs with direct relationships be treated as significant factors. However, airport operators should equally monitor service performance to achieve the highest tourist’ satisfaction in all three constructs to make tourists loyal since any service compromise can interrupt tourists' satisfaction. The findings have economic significance in improving tourism performance and airport service management.

The study determined the influence of burnout, self-awareness, and work engagement on teachers' psychological well-being. Moreover, it aimed to find the best-fit model to explain teachers' psychological well-being. A total of 300 College teachers in private education institutions participated in the study and were selected using the purposive sampling technique. Sets of adopted survey questionnaires were utilized in obtaining data from the respondents. The mean and standard deviation, Pearson r correlation, multiple regression analysis, and structural equation modeling were utilized as statistical tools in the study. The results revealed that the degree of burnout, level of self-awareness, and level of psychological well-being of teachers were moderate. On the other hand, the teachers had a high level of work engagement. Moreover, there was a directly proportional relationship between self-awareness and psychological well-being, and work engagement and psychological well-being. However, an inverse relationship was observable between burnout and teachers' psychological well-being. Further, burnout, self-awareness, and work engagement significantly predicted teachers' psychological well-being. Furthermore, the hypothesized model showed that both burnout and work engagement, directly and indirectly, affected teachers' psychological well-being through self-awareness acting as a mediator. Hence, the hypothesized model was a good fit for explaining teachers' psychological well-being.
Comparison of Conventional Radiography and Multidetector Computed Tomography Scan in Knee Trauma in Rajavithi Hospital
Authors: Mani W. , Yindee K. , Sawarin C.
Published: March 2024

Objective: This study aimed to compare the diagnostic results and agreement among XR, MDCT, and combined examination between XR and MDCT in diagnosing knee bone fractures.

Methods: A retrospective was conducted of 243 patients who experienced knee trauma and underwent both XR and MDCT scans between January 1, 2016, and January 1, 2021, at Rajavithi Hospital in Bangkok, Thailand.

Results: Out of the 243 patients, 147 were male (60.5%), and 96 were female (39.5%), with 226 (93%) displaying fractures. MDCT identified a total of 319 fractures in various anatomic regions. Computed tomography scans compared with the two combined methods showed no difference in results. However, the radiography results were significantly different compared to the two methods combined (p<0.05). MDCT+XR proved more effective in diagnosing fractures than XR alone. The agreement between MDCT versus MDCT+XR exceeded 0.98, whereas the agreement between XR versus MDCT+XR was less than 0.9, except for femoral fractures (0.935). Overall, utilizing both MDCT and XR together significantly enhanced the diagnostic effectiveness compared to using XR alone.

Conclusion: MDCT imaging provides more accurate results, while XR imaging is still valuable for certain fractures. The combined methods were more accurate, especially in cases where the fracture type and characteristics cannot be determined with XR alone. The high level of agreement between XR and MDCT supports the combined use of both methods in clinical practice for diagnosing knee injuries.

Published: March 2024

Objectives: The aim of the study was to evaluate the demographic information, clinical features, surgical methods, postoperative complications, and outcomes at 6 months for patients with choledochal cysts who were treated at the Sheikh Russel National Gastroliver Institute and Hospital. The goal was to assess the outcomes of radical cystectomy versus partial hepatectomy in the treatment of choledochal cysts. Methods: This was a retrospective analysis of 36 patients who had choledochal cysts and were treated with either a total cystectomy (n=30) or partial hepatectomy (n=6). Results: The groups that underwent radical cystectomy and partial hepatectomy had similar age ranges, sex distributions, and types of cysts. The majority of the cysts were type I (83.3% of the total cystectomy group) and type V (100% of the partial hepatectomy group). Other associations included: gallstones (26.7% vs. 83.3%) and Abnormal pancreatic biliary duct junction (APBDJ) (36.7% vs. 16.7%). An increased frequency of post-operative pain, jaundice, upper abdominal swelling, and fever was noted in the group that had a radical cystectomy. Minimal post-operative complications were seen in both groups. At 6 months, the rates of complications were similar, with hypertrophic scars being the most common (30.7% for radical cystectomy and 25% for partial hepatectomy). Conclusion: The groups that had radical cystectomy and partial hepatectomy were of similar demographics, cyst types, abnormalities, clinical traits, and complication rates post surgery and at 6 months. Both procedures are still good ways to treat choledochal cysts, and this small group doesn't clearly show which is better. To get a better idea of differences in long-term results, bigger studies are needed.

Authors: C. A. Raju, , S. Shamshad Begum, , B. Kalpana,
Published: March 2024

Amla processing generates a significant amount of amla residue, known as amla pomace, which is a valuable byproduct. Amla pomace is rich in nutrients and can be utilized as a raw material for further processing and value addition. In this study, peanut chikki was developed by adding amla pomace powder as a functional ingredient at different levels (2%, 4%, and 6%) along with peanuts, and compared with a control sample. The chikki with 6% amla pomace (T3) had the highest overall acceptability score (7.85) compared to other variations. The nutrient composition of the most preferred chikki included protein (10.2g), fat (15.6g), dietary fiber (6.5g), carbohydrates (50g), and 26 mg/100g of ascorbic acid. Storage studies showed an increase in moisture, and peroxide value, a decrease in sensory scores and ascorbic acid content over time. However, the microbiological load remained within acceptable limits. This study demonstrates that amla pomace powder can be successfully incorporated into peanut chikki, providing nutritional and health benefits while addressing waste management issues.

Published: March 2024

The present investigation makes an attempt to study the effect of land configuration on yield, water use efficiency and economics for cropping sequences in dryland area of Central India. Different cropping sequences soybean-chickpea, maize-chickpea and greengram-chickpea were adopted under different sets of land configurations such as Furrow Irrigated Raised Bed (FIRB), Broad Bed Furrow (BBF) and Flat System as Farmer’s Practices (FP). Various yield attributes such as plant height, dry matter per plant, branches/plant, pods/cob per plant, seeds/cob per plant, 100 seed weight, seed and stover yield along with Seed Equivalent Yield (SEY), gross and net return, Benefit Cost ratio, Rain Water Use Efficiency (RWUE) were evaluated in this study. In case of SEY, for soybean-chickpea, maximum SEY was observed in FIRB (3197 kg ha-1), followed by BBF (3131 kg ha-1) and FP (2870 kg ha-1). Similarly for maize-chickpea, highest SEY was detected in FIRB (3601 kg ha-1), followed by BBF (3485 kg ha-1) and FP (3241 kg ha-1). A similar trend was obtained for greengram-chickpea where FIRB expressed highest value of SEY (2121 kg ha-1) followed by BBF (2065 kg ha-1) and FP (1805 kg ha-1). The analysis of yield attributes along with economics clearly suggested that for all combinations of crop sequences, FIRB yielded better results over BBF and FP. The results obtained through this study clearly advocates the fact that sowing of rabi crops on such land configurations (FIRB and BBF) amplifies the crop yield due to the presence of residual moisture which ultimately leads to enhanced farm income.

Published: March 2024

Field pea [Pisum sativum (L.) var arvense] is an important pulse crop mainly grown as a winter vegetable in the plains of north India. The effect of ready-mix application along with various pre- and post- emergence herbicides were evaluated for effective and season long weed control in pea. Pre-emergence application of pendimethalin +imazethapyr (ready-mix) at 1250 g ha-1 provided excellent control of Coronopus didymus, Anagallis arvensis and Chenopodium album similar to weed free conditions and resulted in highest yield (1795 kg ha-1) among the herbicidal treatments. Post-emergence (2-4 leaf stage) application of imazethapyr alone and its different ready-mix combinations with imazamox at 60-80 g ha-1 provided 86.0-94.0% control of weeds at 60 DAS and resulted the grain yield ranging 1503-1620 kg ha-1.The maximum weed control index at 30 DAS (91.5%) was recorded with pre-emergence application of pendimethalin + imazethapyr at 1250 g ha-1 followed by pendimethalin + imazethapyr (PRE) at 1000 g ha-1 (87.80%). Pre-emergence application of pendimethalin + imazethapyr (RM) at 1250 g/ha gave the highest net return along with the highest Benefit Cost Ratio (2.36) followed by the same combination at 1000 and 800 g ha-1.

Published: March 2024

The research was conducted during season 2020 in Al-Shallalat area, 5 km northeast of Mosul. The study included three factors, namely, the treatment of seed soaking with water and the bacterial inoculum, two local cultivars of chickpea: large seeds (Kabuli) and small seeds (Desi) and three levels of phosphate fertilization (zero, 50 kg, and 100 kg P2O5. h-1). The study was conducted according to the factorial experiment system, in (R. C. B. D) design. In three replication, some traits of plant are obtained such as: plant height (cm), the height of the first pod above the ground (cm), pod length (cm), number of seeds/ pod, number of pods/plant (total), number of pods/plant (full) number of pods cleavage (empty), percentage of yield, the weight of 100 seeds (g), biological yield (g/plant), Seed yield (g/plant) and harvest index. The results indicate a significantly excelled of the treatment of soaking with bacteria inoculum on the treatment of soaking with water for all the studied traits. And highly significantly excelled in most of the studied traits of Kabuli over Desi cultivar. Most of the binary and triple interactions recorded a significant difference between the bacterial inoculum and the seeds of the Kabuli cultivar.

Jamun is propagated by seeds as well as vegetatively and the grafts raised on seedling rootstocks of unknown source resulting in variation among the plants. Hence, there is a need to identify the suitable rootstock for propagating jamun to get maximum graft success. The time of grafting is the most important factor for highest graft success and influenced by the climatic conditions prevailing in particular season in addition to the type of rootstocks. Considering the above factors the research was carried out at Kittur Rani Channamma College of Horticulture, Arabhavi during 2018-2019 to study suitable season and rootstock for the jamun variety AJG-85, which is more popular variety in and around Belgaum district. Jamun variety AJG-85 grafted on its own rootstock during October recorded the maximum number of sprouts (3.92, 4.49 and 4.56 respectively), sprout length (7.91, 16.18 and 22.20 cm respectively), per cent graft success (79.39, 88.80 and 90.94% respectively), per cent graft survival (93.96 and 89.30% respectively) at different days after grafting and minimum number of days taken for sprouting (19.15).

The aim of the present study was to assess the potential of natural compounds for the control of Varroa destructor in colonies of Apis mellifera, the antimite potential of the hydrolate and ethanolic extract (Leatricina®) of creosote bush (Larrea tridentata) was evaluated at a concentration 50%; contrasting them with the synthetic chemical amitraz and control under in vitro conditions (48 h) and in the hive (52 days). There were differences (p<0.05) in In vitro Varroa mortality with amitraz with higher values (97.9%) compared with hydrolate (53.1%) and Leatricina® (51.5%); Creosote bush extracts were similar (p> 0.05). In the field experiment, the reduction in the percentage of varroa infestation in adult bees was higher 84.9 % (p<0.05) for amitraz, while the hydrolate and Leatricina® showed differences (p<0.05) 49.5 and 72% respectively, the control group showed the lowest values. Even when the effectiveness of synthetic chemicals presents an evident superiority, the average efficacy and other benefits of natural compounds such as creosote bush extracts represent a viable and safe alternative for the control of V. destructor.

A field-based study was carried out during Kharif season in 2022 at Zonal Agricultural Research Station, V. C. Farm, Mandya, Karnataka, India. The soil was sandy loam in texture, neutral in reaction, low in available nitrogen, and medium in organic carbon, phosphorous and potassium status. The experiment was carried out with fodder Maize in randomized block design with 11 treatments and 3 replications. The treatments include varied levels of recommended dose of N (50, 75 and 100%) along with foliar application of nano urea (0.2% and 0.4%) and urea (2%) spray at 20 and 40 DAS, in comparison with RDF alone and control (RDF without N). The application of 100% recommended dose of N + Urea @ 2% spray recorded significantly higher growth parameters such as leaf area and dry matter accumulation at harvest and was on par with 100% recommended dose of N + Nano urea @ 0.4% spray. Significantly higher green fodder yield, dry fodder yield and nutrient content in fodder maize was recorded in 100% recommended dose of N + Urea @ 2% spray and was on par with 100% recommended dose of N + Nano urea @ 0.4% spray. Higher gross returns, net returns and B:C ratio was observed with application of 100% recommended dose of N + Urea @ 2% spray over rest of the treatments.

Published: March 2024

Community Science is a field that goes far beyond the stereotype of home-making and household chores. It is a rich and diverse domain that addresses a wide array of knowledge essential for enhancing the well-being and quality of life for individuals, families, and communities in an ever-evolving world. In the ever-evolving realm of higher education, there is a growing emphasis on incorporating vocational elements into academic programs. This shift aims to connect the dots between conventional classroom instruction and practical, real-world applications. This study delves into the realm of Vocationalization within the context of B.Sc. Community Science degree programs, aiming to evaluate the perception of students regarding this transformation. The B.Sc. Community Science degree was traditionally known as Home Science and was associated with a focus on theoretical and practical knowledge in domestic sciences, now it has evolved to incorporate practical vocational elements that equip graduates with skills necessary for contemporary life and employment. The result showed that in this study only 21% of the respondents expressed the view that Community Science education indeed offers viable vocational opportunities for students to pursue in their future careers, while 16% disagreed with this assertion and substantial majority of 63% of the students appeared to be undecided or neutral on this matter. This shift in curriculum design seeks to enhance the employability and career readiness of students while aligning academic pursuits with industry demands.
First Report of Stem Borer (Xylotrechus smei) Occurrence on Red Sanders Plantations of Tamil Nadu and Gujarat, India

Published: March 2024

This communication presents the first documented case of the stem borer Xylotrechus smei (Cerambycidae: Coleoptera) infesting red sanders in Tamil Nadu and Gujarat, India. The pest was detected in red sanders plantations located in Dharmapuri and Tenkasi districts of Tamil Nadu, as well as in Surat, Navsari, and Tapi districts of Gujarat, India, during August 2023. In both regions, young red sanders trees aged between 2 to 16 years were affected, with incidence levels varying from 2.24% to 10.86% in the affected plantations. Signs of infestation include the presence of galleries, bore holes in cut stems, complete drying, and mortality of the trees. Initially, larvae feed on the bark, and as they mature, they tunnel through the cambium and wood, impeding nutrient flow and leading to tree mortality. The larvae's deep tunneling within the wood makes them difficult to eradicate with pesticides. Adult beetles typically emerge in peak numbers during April to May and November to December, coinciding with their mating period and selection of host plants for egg-laying. This report aims to outline the damage caused by the stem borer in red sanders and document ongoing monitoring efforts to support interim management strategies.

Hydrogels are attractive materials for biomedical applications due to their versatility and excellent biocompatibility. In this study, we report the preparation of poly(ethylene glycol) (PEG) based hydrogels for intraocular applications. We synthesized branched PEG‐succinimidyl propionates (10 kDa molecular weight) and different types of PEG‐amines (linear and branched, 2 and 10 kDa molecular weight). Transparent hydrogels were formed in situ upon chemical reaction of these macromers. The gels were characterized by oscillatory rheometry and NMR experiments. By varying the concentration of macromers, the functionality of the PEG‐amine, and the conditions during cross‐linking, gels with adequate gelation times of approx 5–10 min and gel strengths of approx 350–1500 Pa were obtained. The cross‐linked hydrogels showed no cytotoxic effects and may be used as vitreous substitutes or intraocular drug release systems.
Heterogeneous Raney Nickel and Cobalt Catalysts for Racemization and Dynamic Kinetic Resolution of Amines

Published: December 2007

Raney metals were studied as heterogeneous catalysts for racemization and dynamic kinetic resolution (DKR) of chiral amines, as an alternative to metals like palladium or ruthenium. Both Raney nickel and cobalt were able to selectively racemize various chiral amines with high selectivity. In the racemization of benzylic primary amines, the minor formation of side products, e.g., secondary amines, can be suppressed by varying the hydrogen pressure. In the racemization of aliphatic amines over Raney catalysts, the selectivity is very high, with the enantiomeric amine as the sole product. DKR of racemic aliphatic amines can be performed with immobilized Candida antarctica lipase B and Raney nickel in one pot; for 2‐hexylamine, a yield of 95 % of the acetylated amide was achieved, with 97 % ee. Attention is devoted to the compatibility of the enzyme and the metal catalyst during the DKR. For benzylic primary amines, a two‐pot process is proposed in which the liquid is alternatingly shuttled between two vessels containing the solid racemization catalyst and the biocatalyst. After 4 such cycles, the amide of (R)‐1‐phenylethylamine was obtained with 94 % yield and more than 90 % ee.

Published: December 2007

The effects of hydrostatic pressure on the structure and stability of porcine odorant‐binding protein (pOBP) in the presence and absence of the odorant molecule 2‐isobutyl‐3‐methoxypyrazine (IBMP) were studied by steady‐state and time‐resolved fluorescence spectroscopy as well as by molecular dynamics simulation. The authors found that the application of moderate values of hydrostatic pressure to pOBP solutions perturbed the microenvironment of Trp16 and disrupted its highly quenched complex with Met39. In addition, compared with the protein in the absence of IBMP, the MD simulations experiments carried out at different pressures highlighted the role of this ligand in stabilizing the Trp16/Met39 interaction even at 2000 bar. The obtained results will assist for the tailoring of this protein as specific sensing element in a new class of fluorescence‐based biosensors for the detection of explosives. © 2007 Wiley Periodicals, Inc.
