Impact of trawling speed on vertical opening of trawl net by modelling method
Authors: Nguyen Huu Thanh
Published: February 2024

This study was conducted to find out the relations between trawling speed and vertical opening of trawl net. The study uses a trawl model to perform a test in a flume tank at various trawling speeds, from 0.46 m/s to 1.08 m/s, this is equivalent from1.5 knots to 3.5 knots in the field for full-scale net. The results show that the vertical opening of the net mouth decreases as the trawling speed increases, the vertical opening was reduced by more than 32% as the speed increased from 1.5 knots to 3.5 knots. The regression results show that there is an approximate relationship between trawling speed and vertical opening with a logarithmic function (correlation coefficient R² = 0.9663). The results of this study are entirely consistent with previous field studies conducted in the world.

Cultural Practices and Food Consumption Behaviour of Guests Dining In 4-5 Star Hotels in Nairobi City County, Kenya
Authors:   Kenyatta University, Mwanzia Rachel Ndunge
Published: March 2024

In a culturally diverse market such as Kenya, consumers form a mindset of foods to consume while dining out, have different food preferences, and assume different consumption behavior patterns while making food purchases. Cultural practices may influence their decisions, prohibiting them from eating certain foods. The study sought to investigate the influence of cultural practices on behaviors regarding food consumption of guests when dining out in restaurants found in 4–5-star hotels in Nairobi County. The study’s target population was customers dining out in restaurants in 4–5-star hotels in Nairobi County and respective restaurant managers. A suitable pretest sample of 10 respondents was selected from walk-in customers and three restaurant managers from three restaurants picked from the hotels that were not part of the sample. Cronbach's Alpha obtained from the pre-tested 13 participants was 0.743. The ideal sample size of respondents drawn from restaurants in hotels classified as four- and five-star hotels according to the Tourism Regulatory Authority classification 2016 was determined by proportionate stratified sampling. The sampling technique for the Managers was purposive, selecting each Restaurant's Manager. The estimated number of respondents was 385 from a sample of restaurants in 21 hotels ranked as 4- and 5-star hotels in Nairobi County. Data collection involved questionnaires and direct interviews, yielding an 80.5% response rate with 310 adequately completed questionnaires and seven interviews. The analysis utilized descriptive and inferential statistics, presenting the data in tables, charts, and graphs for each category of variables. The Chi-square Test was employed to assess the relationship between dependent and independent variables at a 95% confidence level. The findings showed a significant association between food taboos and the dining habits of patrons in 4-5 star hotel restaurants in Nairobi County (χ2=8.980, p=0.003), a notable link between cultural beliefs and dining habits in the same context (χ2=22.099, p<0.05), and a significant influence of rituals on these dining habits (χ2=5.361, p=0.021<0.05). The study further established that the decision-making process significantly moderated the relationship between cultural practices and consumption behavior of diners in restaurants in four and five-star hotels in Nairobi County. The study concludes that modern-day food consumption behaviors result from several factors, including culture, taboo, religious beliefs, rituals, and thus food choice diversity. Therefore, 4- and 5-star hotel professionals should factor in the cultural element during menu planning to balance the catering, financial, and marketing policies. Keywords: Cultural influences, food consumption patterns, luxury hospitality, gastronomic tourism, Nairobi city county hospitality.

Influence of Genetic Selection on Rearing Parameters and Production Performance of Two Leghorn Type Pullets, 1940 Random-Bred Control Versus W-36 (2016) Commercial Strain Grown under the Same Regimen
Authors: Narayanan AL
Published: February 2024

The aim of this study was to expand the period of selection history by evaluating the pullet growth characteristics of two genetic stocks of Leghorns reared under identical conditions 1940 Leghorn Strain (WL40) from the University of Arkansas and a 2016 Commercial Hy-Line W-36 (WLCC) from Hy-Line were housed in the same environment, comparing rearing production characteristics from the day of hatch until 16 weeks of age. All chicks were hatched at the Prestage Department of Poultry Science at North Carolina State University and raised in the same cage-rearing facility, with 14 birds per brooding cage then reduced to 10 birds per cage. Pullets were weighed bi-weekly, and feed weigh-backs were concurrent to determine body growth, feed consumption, and utilization. Pullet starter was fed from 0-6 weeks, a grower from 6-12 weeks, and a developer from 12-16 weeks. Diets were provided ad libitum, and mortality was recorded daily. The experiment was a randomized block design using a 2 ×3 factorial design, 2 genetic strains, and 3 dietary phase regimens and all data were statistically analyzed using a one-way ANOVA. Both strains responded similarly, showing an increase in body weights with the 2016 commercial strain exhibiting heavier weights with no significant differences (P>0.05) in all feed phases. Results from this data suggest that layer selection over the years had neutral adverse effects on body weights or feed conversion reared in the same environment and current commercial diet. This indicated that selection preferences for desirable traits such as body weights and feed conversion have been successfully implemented for optimal performance benefiting the 2016 pullet.

Published: February 2024

Right-sided endocarditis represents a distinct clinical condition observed in individuals with a history of parenteral drug use or those with implanted pacemakers or other intracardiac devices. Aeromonas infections, although uncommon in humans, particularly endocarditis cases, are exceedingly rare. Here, we report the case of a 72-year-old female with a medical history of arterial hypertension and chronic kidney disease undergoing hemodialysis via a tunneled permanent central venous catheter. She presented with chills and a fever of 38.3°C. Physical examination revealed a grade 3 protosystolic murmur at the tricuspid focus. Blood cultures from central and peripheral sites yielded growth of Aeromonas hydrophila. Transthoracic echocardiography demonstrated a fusiform, semi-mobile vegetation measuring 16 x 15 mm at the outlet of the superior vena cava, suggestive of endocarditis. Intravenous fluoroquinolones were initiated based on antibiogram results, leading to resolution of imaging findings after a 21-day treatment course.

Authors: Song Jianrui , Zhang He
Published: March 2024

In order to solve the problem of high error in the process of measuring the rheology of drilling fluids by the common pipe flow method, an online measurement device for the rheology of drilling fluids with rectangular tubular drilling fluids was fabricated, and a calibration method for the measurement error of rheological parameters was proposed and corresponding experiments were carried out. By measuring the differential pressure value and flow, flow rate and other parameters when the drilling fluid flows through the measuring tube, upload them to the host computer for processing, use VMD to decompose the measured differential pressure data, remove the residual term, and then perform Hibert transform on each modal component to obtain its analytical signal, modulate the amplitude and phase of each analytical signal, and then reconstruct the signal to obtain the optimized differential data, and finally bring it into the constructed calibration model of the rheological parameter measurement error of drilling fluid to obtain the rheological parameters. The experimental results show that the proposed method can obtain more accurate rheological parameters of drilling fluid, improve the measurement accuracy of drilling fluid rheology parameters, so as to judge the downhole situation more accurately and ensure the personal safety of on-site staff.

Published: March 2024

With the continuous deepening of education reform, the leadership position in the education field has gradually improved. Issues such as leadership style assessment, leadership prediction, teacher leadership ability improvement programs, leadership training and educational reform have received widespread attention. However, there are still some problems and challenges in these areas that require further research and exploration. This study uses empirical analysis methods to conduct a comprehensive analysis of leadership style assessment, leadership prediction, teacher leadership ability improvement programs, and leadership training and education reform issues in the field of education. The results show that in the current field of education, it is crucial to pay attention to issues such as leadership style assessment, leadership prediction, teacher leadership ability improvement plans, leadership training and educational reform. But there are also common problems and challenges in these areas. In terms of leadership style evaluation, inconsistent indicators and standards, uneven methods and tools, and a lack of widespread practical application have become problems that need to be solved urgently. The key to solving these problems is to strengthen research, improve evaluation indicators and methods, improve tool reliability, and transform evaluation results into practical improvement measures. In terms of leadership prediction, prediction accuracy is challenged due to the complexity, multi-dimensionality of leadership and the interference of external factors. Future development requires more careful treatment of forecast results and comprehensive analysis combined with other factors. At the same time, establishing clearer leadership evaluation standards and conducting in-depth research on prediction methods and tools are necessary steps to promote the development of leadership prediction. Teacher leadership capacity improvement projects currently have problems such as systemic flaws, lack of pertinence and sustainability, and imperfect evaluation and feedback mechanisms. In order to improve the effect, it is necessary to build a scientific and systematic improvement plan framework, focus on personalized training, establish a long-term training and development plan, improve the evaluation mechanism, and transform evaluation results into specific improvement measures. Finally, the current status of leadership training and education reform has problems such as uncertain conceptual connotations, resource investment challenges, and differences in actual effects that need to be resolved. Clarifying leadership standards, optimizing training methods, and improving training effects are the directions to promote the integrated development of leadership training and education reform. At the same time, an effective evaluation and feedback mechanism should be established to provide scientific support for continuous improvement.

Authors: Xu Guideng , Yan Yikang
Published: March 2024

The content of marketing major includes human resources, finance, sales, logistics and other management contents in the field of management, with some hybridity. Insufficient cognition on the major and one's own psychological characteristics affects the optimal allocation of time during college years, which in turn affects academic performance and employment. Through questionnaire surveys of current students and interviews of graduated students majoring in marketing at Ningde Normal University, this paper analyzes students' academic and employment cognitions. Some lower-grade students majoring in marketing have vague cognitions about their major. In addition to the unclear cognitions about the major, like students of other majors, a certain proportion of students also lack clear cognitions about their own psychological characteristics. After students start learning marketing, it is necessary to improve their cognitions about the major through various means. Offering career planning courses in the first semester enables students to cognize the major and themselves earlier, so that they can engage in purposeful learning and training during college, which is beneficial for their academic development and employment.

Published: March 2024

For some problems of the traditional A* algorithm in robot path planning, such as inefficient search, many and complex inflection points in the designed and realized paths, as well as the inability to complete real-time dynamic path planning for obstacle avoidance, this paper proposes an improved A algorithm and combines it with Floyd for path rounding, and finally with DWA (Dynamic Window Approach) algorithm to be Fusion. In the improved A* algorithm, a carefully normalized random obstacle environment is used and the search process is optimized by reducing the search direction and redundant nodes. Meanwhile, the evaluation function is adjusted to achieve the optimal global design solution, and path optimization and obstacle avoidance are performed by the DWA algorithm. The experimental results finally show that when the robot is in a complex environment, the fusion algorithm can ensure the completion of the globally optimal route while avoiding obstacles in a timely and effective manner, which realizes more efficient path planning.

They were divided into (20) as a study group with moderate to severe chronic periodontitis, and (20) chronic gingivitis patients were chosen as a control group. Gingival crevicular fluid and serum samples were collected at baseline and six weeks after therapy for the study group and at baseline for the control group. Systemic and local levels of 25-hydroxy vitamin D3 were measured using an enzyme-linked immunosorbent assay (ELISA) technique. The study group of diseased patients received initial periodontal therapy (SRP). The study showed that respective local 25-Hydroxy vitamin D3 levels significantly increased from baseline up to six weeks after (SRP) (3.41ng/ml versus 4.57ng/ml), P=0.022. The respective systemic 25-Hydroxy vitamin D3 levels significantly increased after six weeks from SRP (39.88ng/ml versus 41.48 ng/ml), P=0.001.
