Introduction: Metabolic syndrome and diabetes are emerging diseases nowadays. so adjuvant therapy which is without harmful side effects has become the subject of various researches. Its beneficial effect has been proven however its place in the diet of obese subject remains to be dicovered. The subject of our work is to study the effects of flax seeds on lipids. insulin and ghrelin in women with type 2 diabetes with metabolic syndrome. Method: We followed a population of 50 women with type 2 diabetes with metabolic syndrome who consumed 30g / d of flaxseed for 8 weeks. Then we compared the anthropometric and biochemical parameters at T0. T4 and T8 weeks. for the hormonal parameters we measured only between T0 and T8 because it is an expensive dosage. Results: Improvement of the various parameters followed after consumption of flax seeds in our study group. This improvement is significantly better after 8 weeks. For glycemia. CT. TG. HDL-C. IMC. TT. PAS. PAD. insulinemia. ghrelinemia and resistinemia (p between 0.00 and 0.01 for all these parameters studied). Discussion: Because of their high fibers and in SDG content. the flax seeds improve the anthropometric parameters. probably they favor a better glycemic profile by their richness in omega 3. The flax seen its contents rich in ALA shows an effectiveness to reduce the figures of the plasma lipids as well as the improvement of hormonal parameters. Conclusion: In the end. this study. combined with the literature. allowed us to better understand the importance of the seeds of this plant in the diet of obese subjects with metabolic syndrome. Enriching your diet with these seeds would therefore be an effective means in the fight against obesity and metabolic syndrome.

Authors: Oriji O. G  , Okpara-Akpotu J. O
Published: September 2023

The research focuses on the comprehensive analysis and quantification of biogenic amines in dry fish samples, an essential aspect of food safety and quality. To achieve accurate and reliable results, a robust analytical method was adopted using high-performance liquid chromatography (HPLC) equipped with DAD UV/ Vis detector. The extraction of biogenic amines from dry fish samples was optimized to ensure maximum recovery, and suitable derivatization techniques were employed to enhance the detectability of these compounds. Nine (9) biogenic amines; Histamine (HIS), Cadaverine (CAD), Tyramine (TYM), Ethylamine (ETH), Methylamine (MET), Putrescine (PUT), Typtamine (TYP), Agmatine (AGM) and Isoamlamine (ISO) were analyzed in the fish samples. The correctness and repeatability of the method were assessed by performing replicate analyses (n = 3) for two samples of dried fish from Mile 2 and Choba sites respectively. The detection levels of biogenic amines in the dried fish samples ranged from 1.mg/kg to 1.70 mg/kg for agmatine; from 0.03 mg/kg to 0.04 mg/kg for cadaverine; from 5.52 mg/kg to 5.60 mg/kg for Ethylamine; from 0.42 to 0.48mg/kg for histamine; from 7.15 mg/kg to 7.16 mg/kg for Methylamine; from 5.13 mg/kg to 5.29 mg/kg for Isoamalamine; from 0.84 mg/kg to 0.90 mg/kg for Putrescine; from 2.70 mg/kg to 2.90 mg/kg for tryptamine and from 4.26 mg/kg to 4.44 mg/kg for tyramine across all sample locations respectively. The maximum histamine, Cadaverine and Agmatine detection levels were significantly less than other bioamines detected. Nine biogenic amines were detected where Cadaverine tends to be the lowest and high Methylamine concentration was recorded in both samples, though less than those of the regulation and recommendation set by the EU regulations and national standards for fish products.
Effects of teenage pregnancy among female learners: A case of selected secondary schools in Kapiri Mposhi district of central province, Zambia
Authors: Chanda Chansa Thelma
Published: September 2023

Teenage pregnancy is when a woman under the age of 20 gets pregnant. It usually refers to teens between the ages of 15-19. Teen pregnancy or adolescent pregnancy is the pregnancy of girls aged 10-19 years, leading to many maternal and neonatal adverse effects. These pregnancies have been a global concern for many decades and yet are still prevailing. Pregnancy can occur with sexual intercourse after the start of ovulation, which can happen before the first menstrual period (menarche). In healthy, well-nourished girls, the first period usually takes place between the ages of 13 to 16. It was for this reason that the study was conducted to analyze the effects of teenage pregnancy among female learners in Kapiri Mposhi district of Central Province in Zambia at some selected secondary schools. The study adopted a mixed methods approach which is a combination of quantitative and qualitative data. The sample involved a total of 110 respondents which included; two (2) health workers, from Kapiri General hospital, three (3) head teachers, twelve (12) teachers and ninety-three (93) learners. The respondents were obtained through purposive and simple random sampling. Data was obtained through interviews and questionnaires from the selected secondary schools. Data analysis consisted of content analysis of the interview responses and item analysis of the questionnaire responses; the data gathered were analyzed according to the themes of the study and the order of the research objectives. Data generated from the questionnaires were analyzed manually using the Statistical Package for Social Sciences (version 26) and Microsoft Excel (version 16) to come up with frequency tables, pie charts and bar graphs. The findings indicated that due to teenage pregnancies, there was high levels of school drop-out rates on female learners. Also, the study revealed that poverty, lack of education, lack of information about sexual and reproductive health, child marriages, sexual violence and drug abuse among others, resulted into teenage pregnancies in Kapiri Mposhi district.
Fuzzy logic controller-based enhancement for grid-connected large-scale PV systems
Authors: Mohamed Belrzaeg  , Mohamed Abou Sif
Published: September 2023

: In recent years, considerable scholarly attention has been directed toward photovoltaic (PV) power generation, driven by the imperative to ameliorate the ecological ramifications inherent in conventional electricity generators. The economic viability of PV generation is intrinsically contingent upon both the cost-efficiency of the cells employed and the quantum of energy that the arrays have the capacity to deliver over their operational lifespan. This scholarly exposition elucidates an exploratory inquiry into the intricate realm of modeling and simulating solar PV systems, conjoined with the distribution grid via the employment of a Fuzzy Logic Controller (FLC). The inquiry delves into the nuanced realm of the influence wielded by fluctuations in solar radiation upon the system's operational efficacy, concurrently proffering a novel energy storage framework engineered to counterbalance the power quality predicaments stemming from the intermittent nature of solar energy. The empirical manifestations gleaned from simulations evince the system's conceptual prowess, effectuating an amelioration in the comprehensive operational dexterity of the solar PV system, thereby embellishing energy capture efficiency and mollifying the perturbing power quality predicaments. A comparative investigation, encompassing varied conditions, substantiates the prowess of the proposed methodology vis-à-vis the fixed perturbation Maximum Power Point Tracking (MPPT) algorithm. Empirical observations emanating from these investigations conspicuously affirm the feasibility and distinct advantages underpinning the purview of the proposed methodology.

Published: September 2023

This study aims to assess children’s reasoning ability, namely following the crises in Lebanon, and to identify those in need. A pilot study was conducted in April-May 2023, targeting children between 6 and 11 attending grades 1 to 5. The sample (130 students) comprised more females (60.5%) than males (39.5%). The score for simple pattern completion was significantly higher among students aged 8-11 (9.58 over 11) than their younger peers (8.38; p=0.007). This score showed statistically significant variation depending on the student’s grade, with the lowest score at grade 1 (6.88), which significantly increased at grade 2 (9.44) and attained its maximum value at grade 4 (10.72), then decreased again at grade 5 (9.03; p<0.001). Male students (9.33) had higher scores than females (8.84) with no statistical significance (p>0.05). The parent’s characteristics did not statistically affect these scores, but students with older and married parents and those with better economic situations had higher scores. The score in discrete and continuous pattern completion was significantly higher among older students (10.68) than their younger peers (7.24; p<0.001) and per grade increase. Educators can support the development of fluid intelligence in schoolchildren through activities that encourage problem-solving, critical thinking, and creative exploration.

Published: September 2023

The recreational use of nicotine vaping and cannabis among teenagers has become increasingly prevalent in recent years, raising concerns about potential health risks. This case report highlights the association between prolonged toxic habits and the occurrence of a rare but severe cardiac event known as Non-ST-segment elevation myocardial infarction (NSTEMI) in a teenage individual. A comprehensive review of the patient's medical history, including cannabis and nicotine consumption patterns and cardiovascular risk factors, was conducted. The findings indicate a strong temporal relationship between prolonged cannabis and nicotine vaping usage and the development of an NSTEMI incident in this teenager. The pathophysiological mechanisms underlying this association are discussed, including the impact of cannabis on cardiovascular function, its potential to induce arterial vasoconstriction, and its prothrombotic effects. Additionally, the role of coexisting risk factors, such as anxiety, is mentioned to elucidate their contribution to the development of NSTEMI. The implications of this case highlight the need for increased awareness among healthcare professionals, educators, and parents regarding the potential cardiovascular risks associated with prolonged cannabis usage in teenagers. Early identification of cannabis use and prompt intervention are crucial to prevent life-threatening cardiac events in susceptible individuals. Further research is warranted to explore the precise mechanisms linking cannabis use and NSTEMI incidents, enabling the development of targeted preventive strategies and evidence-based interventions to mitigate the potential harm caused by cannabis consumption in the adolescent population.

Authors: Thiwanka Sandaruwan De Fonskea  , Mohideen Bawa Mohamed Ismail
Published: September 2023

After oil, apparel is the second most polluting industry in the globe. Therefore, the implementation of environmentally sustainable practices in the apparel industry is a hotly debated topic around the globe. Sri Lanka's principal export revenue generator is the apparel industry, which accounts for more than forty percent of its export revenue. This research was conducted to identify the barriers that challenge in embedding environmental sustainability practices in Sri Lanka's apparel industry. Using a mixed method approach, quantitative data were collected via an online questionnaire survey (205 respondents) and qualitative data were collected via semi-structured interviews (30 interviews). Using universally accepted scientific methodologies, sample size, and data analysis methods were determined. The researcher was unable to locate any similar scholarly work on Sri Lanka's apparel industry, despite finding numerous studies on the same topic for other important apparel-producing nations in Asia and Africa. Consequently, five barriers, namely lack of environmental awareness, lack of financial resources, lack of management commitment and leadership, poor organizational culture, and lack of technology were extracted from the extensive literature review conducted using previous scholarly work from other countries and evaluated for the Sri Lankan context using the quantitative and qualitative data mentioned above. All these barriers were found to be pertinent to Sri Lanka's apparel industry, with lack of financial resources being the most challenging and lack of environmental awareness being the least challenging barrier. None of the respondents mentioned any other barriers apart from those listed above.

Published: September 2023

Sugar, available as sucrose, is a natural ingredient that has always been part of the human diet, providing cellular energy source. Its consumption has been linked to several metabolic diseases. This study is therefore designed to assess the effect of oral table or white sugar on sperm parameters and antioxidant status of adult male Wistar rats. Twenty adult male Wistar rats (100-180g) were randomized into 4 groups of 5 rats. Group 1 (Control) received distil water. Groups 2, 3 and 4 rats received 20mg, 30mg and 60mg of table sugar per Kg bw respectively. After 30days oral treatment, a testes (with its epididymis) was removed for sperm function test and blood was withdrawn from each rat through cardiac puncture for superoxide dismutase and glutathione peroxidase antioxidant enzyme assays under chlorofoam anaesthesia. Data obtained, expressed as means ± SEM, were analyzed using ANOVA. Result showed significant reduction in body weight and sperm parameters (count, normal motility/progressivity and normal morphology) in the treated groups compared with control. Sperm abnormal motility and abnormal morphology were significantly increased in the treated group compared with control. Antioxidant assays showed no significant change in the treated groups relative to control. These findings suggest that table sugar adversely impact sperm functions well below the RDA of table sugar and may therefore, promote male fertility.

Published: September 2023

Utilization of renewable energy in Aceh is still limited mainly to small-scale electricity through micro-hydro and solar power plants, accounting for less than 1% of the energy composition. Sabang stands out as a region with significant wind energy potential, boasting a speed of 8 m/s and an average power density of 537 W/m2 for the windiest 10% of the region. Therefore, to explore the viability of harnessing wind energy, a pre-feasibility study is needed. This study aimed to assess the techno-economic feasibility of constructing a wind power plant for electricity generation in Sabang by evaluating the region's wind energy. The statistical method of the Weibull Distribution probability density function was employed to evaluate Wind Power Density (WPD), Wind Turbine Capacity Factor, and Energy Output. Additionally, economic feasibility analysis involved calculating Net Present Value (NPV), Benefit Cost Ratio (BCR), Internal Rate of Return (IRR), Discounted Payback Period (DPP), and Levelized Cost of Energy (LCOE). The results showed that Sabang exhibited favorable[UMN1] wind characteristics with a shape parameter (k) of 1.6, average wind speed (Vm) of 7.9 m/s, and scale parameter (c) of 9 m/s. These features classified Sabang as wind power class 6 with a WPD of 735 watts/m2 at a height of 50 m, and the results were categorized as excellent. The study concluded that constructing a wind power plant in Sabang using the Enercon E-70 turbine at a hub height of 100m was technically feasible. The shape parameter (k) was 1.6, the average wind speed (Vm) was 9.3 m/s, scale parameter (c) was 11 m, and the WPD reached 1213 W/m2, leading to a turbine capacity factor of 0.53 and an annual energy production (AEP) of 64,876,560 kW. The economic analysis yielded promising results for wind power projects. The DPP value was estimated at 5.6 years, the BCR at 1.96, the NPV amounted to USD 14,434,994, the IRR reached 17.9%, and the LCOE was assessed at USD 32.50/MWh. Considering all these economic indicators, it was evident that constructing a wind power plant in Sabang was highly feasible and financially viable

This paper discusses the process of optimizing the truss structure step by step from 2D to 3D space using finite element analysis. This step-by-step optimization process is carried out to simplify the analysis of truss structures from simple to more complex cases. Optimization aims to obtain the minimum cross-sectional area and weight for each truss member. The stages of the optimization process carried out in this study are starting from a 2-dimensional (2D) truss structure with several two and five members to a 3-dimensional (3D) one-level tower with a total of 18 members. The optimum criterion as the constraint used is the full stress design method and the value of the cross-sectional area and weight of the structure as a result of optimization, leading to convergence during the iteration process. The tool used to run the iteration process is performed using Fortran software. The results of this optimization process are the total cross-sectional area (A) and a minimum of weight (W), that is, for a two-member truss A = 1 in2 and W = 4 lb, for a five-member truss A = 3.48 in2 and W = 14 lb. Furthermore, for a one-level of tower-space truss with a total of 18 elements, A = 57.91 in2 is obtained and the optimum weight of the truss structure is W = 134.02 lb. From these results, it can be seen that the optimization process that starts from simple to complex cases can be carried out easily and still takes into account the existing constraints

The Aims of this study are to determine the effect of embossing roll roughness and forming temperature on the damage of menthol-coated aluminum foil on the packaging, and to determine the best temperature and embossing roll roughness on the quality of the menthol coating on the packaging. In this study, the independent variables were embossed roll wave (roughness level 1000,500.0 µm) and menthol foil temperature (22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46 °C) to be manipulated, observed, and measured to know the effect with the dependent variable. And because the established variable is the quantity of broken menthol foil packaging that is measured via way of means of calculating the share of period of menthol foil packaging this is torn as compared to the whole period of the foil. Based on the effects of the discussion, it can be concluded that the forming temperature and the embossing roll roughness affect the damage to the menthol packaging layer. In the ANOVA follow-up test, the lowest and best mean value for the forming temperature is at T12 or 44°C, not at T13 or 46°C because at these temperatures the menthol layer on the package is too hot and starts to damage the coating and the lowest and best average for the roughness level of embossed rolls is at E3 with a roughness value of 0 µm (fine).

ABSTRACT

The development of the agricultural sector, especially food crops, in Manokwari district, supported by an extension system which is institutionally under the coordination and management of the Agricultural Extension Center under the Manokwari District Agriculture Office. The extension activities are managed by the Agricultural Extension Center (BPP), as many as 4 Balai, namely Masni, Prafi, Warmare, and Manokwari. These four BPPs are supported by 88 Field Agricultural Extension Workers (PPL). Currently, the Manokwari Regency Agricultural Extension Center is in charge of coordinating and fostering 4 BPPs in Manokwari Regency, namely, BPP Masni, BPP Prafi, BPP Warmare and BPP Manokwari. This study aims to assess the existing condition of BPP Prafi, evaluate the performance of PPL in WKBPP Prafi, identify factors that affect the performance of PPL. This research took place from 06 July 2021 to 05 August 2021. The place of implementation was at (WKBPP) at BPP Prafi, Manokwari Regency. The method used is descriptive method. The subjects in this study were PPL at (WKBPP) Prafi. The sampling method is by census. The data collected are primary and secondary data. Data analysis was done by tabulation with a frequency distribution to assess PPL performance, while to find out the factors related to PPL performance were analyzed using tabular analysis. Based on the results of research that has been carried out in Prafi, Manokwari Regency. The performance of field agricultural extension workers in Prafi, Manokwari Regency, was declared in the good category. This is supported by three indicators as parameters, namely indicators of extension programs, implementation of agricultural extension, evaluation and reporting. PPL in Prafi has implemented an extension program, compiling a work schedule in which joint visits with extension workers and field visits must be at the invitation of the farmers. In addition, the extension workers have applied the principle of learning while working because the PPL's job is not only to be a lecturer but also to go out in the field to help the fostered farmers carry out planting, harvesting and selling. The factors that influence the success or failure of PPL are success factors, namely education level, age, and length of work. Keywords: PPL Performance

Effects of Green Spaces on Microclimate in Sustainable Urban Planning

Published: September 2023

In recent years, there has been a growing importance placed on the development of various models and scenarios aimed at mitigating the effects of climate change. This approach is gaining prominence in our country as well. This study is based on research conducted in the Yeşilyurt neighborhood within the Tarsus district of Mersin province. The primary objective of this research is to assess the impact of increased green space on microclimate conditions using ENVI-met simulation. Within the scope of this research, a comparison was made between the current situation and a scenario in which the amount of green space was increased. The analysis of green area quantities was conducted using the ENVI-met simulation software, utilizing climate data such as temperature, humidity, wind direction, and speed, which were obtained through measurements. In the scenario involving an increase in green space, the total green area was augmented from its current 2,487 m² to 4,398 m². The simulation results underscore the substantial effect of this augmentation on the microclimate. Average temperature values fluctuate between 31.11°C and 33.04°C, revealing that the expansion of green space leads to a reduction in temperature, thereby positively impacting the environment. This translates to an overall temperature decrease of approximately 0.45°C across the entire area. The research highlights the favorable influence of heightened green space on microclimate conditions, as evidenced by findings derived from ENVI-met simulations. It elucidates how such an increase can contribute to temperature regulation. These outcomes underscore the significance of deliberate green space incorporation in urban planning and design processes, guiding decisions that promote environmental sustainability. Thus, it is recommended that forthcoming strategies of local governments prioritize the expansion of green areas while considering factors related to microclimate and environmental quality.
