ВЛИЯНИЕ ВЫЕДАНИЯ РЫБАМИ НА РАЗВИТИЕ ЗООПЛАНКТОНА (ЭКСПЕРИМЕНТЫ В ПРОТОЧНОЙ ЭКОСИСТЕМЕ)
Authors: ГЕРАСИМОВА Т Н. , САДЧИКОВ А П. 
Published: December 2024

Патриарший пруд - небольшой водоем в черте г. Москвы. В нем отмечено регулярное и массовое цветение зеленых водорослей. Многие виды рыб имеют продолжительный порционный нерест в течение всего лета. В пруду постоянно присутствует молодь рыб разного размера, которые потребляют крупных особей зоопланктона. Из-за этого размерная структура популяции сдвигается в сторону мелких видов. Simocephalus vetulus в водоеме был зарегистрирован только один раз (24 июля). Его численность составляла - всего 0,1 экз./л В дальнейшем, вплоть до окончания исследований он не встречался в пруду, хотя в экспериментальной экосистеме (куда он проник из водоема) развивался очень хорошо. В проточной экосистеме (при отсутствии рыб) численность S. vetulus в августе достигла 11880 экз./л. В пруду он отсутствовал, что связано с его выеданием рыбами. В пруду зарегистрировано 23 вида зоопланктона. Самые многочисленные - это коловратки. Они являются показателем наличия в водоеме большого количества взвешенных частиц (водорослей, детрита). В составе фитопланктона зарегистрировано 106 видов водорослей и цианобактерий. В составе зеленых водорослей - 67 видов; среди которых многие представлены колониями размером 100-250 мкм, погруженными в слизь. При воздействии зоопланктона колонии разрушаются и используются в пищу зоопланктоном.
The Patriarshii Pond is a small water body within Moscow boundaries. It shows regular and mass blooming of green algae. Many fish species have long, portioned spawning cycles throughout the summer. The pond is constantly inhabited by juvenile fish of various sizes, which consume large zooplankton organisms. Because of this, the dimensional structure of the population shifts towards smaller species. Simocephalus vetulus was recorded in the water body only once (July 24). Its abundance was as low as 0.1 spec./L. After that, up to the end of the study, it was never seen in the pond, though it developed very well in an experimental system (into which it penetrated from the water body). In the flow-through ecosystem (in the absence of fish), the abundance of S. vetulus in August reached 11 880 spec./L. It was not found in the pond because of its grazing by fish. Twenty-three zooplankton species were recorded in the pond. Rotifers are the most abundant. They indicate to the presence of large amount of particulate matter (algae, detritus) in the water body. Phytoplankton is represented by 106 species of algae and cyanobacteria and the green algae, by 67 species, among which many form colonies with a size of 100-250 /ни. immersed in mucus. Under the effect of zooplankton, the colonies are destroyed and used by it as food.

Purpose: Kitchen sponges, commonly used to clean kitchen items and surfaces, can become a significant source of cross-contamination if handled, stored, or disinfected poorly. This study, therefore, plays a crucial role in raising awareness about the potential risks of pathogenic bacteria transfer to food-contact surfaces by evaluating the microbial quality of sponges used by street food vendors.
Design/Methodology/Approach: A brief questionnaire was administered to ascertain the dishwashing activities at the food vending sites. Thirty-two (32) sponge pieces collected from street food vending sites within the Sunyani Technical University vicinity were examined for their microbial levels, and the data were analysed using MS Excel and SPSS version 20.
Findings: Eighty-six percent (86%) of the food vendors surveyed indicated that the Food and Drug Authority (FDA) and Environmental Health Officers (EHO) from the municipal assembly supervised their businesses, and 62% possessed a medical examination certificate. More than half of the food vendors (62.5%) only changed the dishwashing water 1-3 times per day, and 69% did not replace the sponge until it was completely damaged. Most respondents (87%) drained washed dishes (bowls) by tilting, and 69% of food vendors placed the sponges in a designated sponge container without drying them. There was relatively high microbial contamination in the wash sponge and water, exceeding recommended levels with a strong correlation between the two.
Research Limitation: This research focused on wash sponges at street food vending sites near Sunyani Technical University; hence, the scope of generalisation might be limited.
Practical Implication: The study may impact how street food vendors handle and store wash sponges.
Social Implication: This project will help street food sellers become more aware of food safety procedures, lower the number of cases of foodborne illnesses, and enhance general health and well-being.
Originality/ Value: The study investigated the microbial quality of sponges, a critical but often overlooked aspect of food safety in the food service industry.

The objective of this study is to evaluate the effectiveness of creep feed containing Indigofera and Black Soldier Fly (BSF) maggot meal and Indigofera on the performance and meat quality of Dorper lambs. The study involved 21 male lambs aged 3 months with an average weight of 20.03 ± 1.71 kg. A Completely Randomized Design (CRD) with 3 treatments and 7 replications was used, namely PM = Martabe feed, P1 = Indigofera creep feed, and P2 = BSF maggot creep feed. Parameters observed included performance, carcass characteristics, physical meat quality, nutrient composition, and fatty acid profile of Dorper lamb meat. Data were analyzed using Analysis of Variance (ANOVA), and significant differences were further analyzed using Duncan's test. The results showed that P2 significantly increased (p<0.05) consumption, daily weight gain, and carcass percentage compared to the other treatments. Although P1 did not show a significant difference in performance compared to the other treatments, it significantly affected (p<0.05) the protein content and improved the fatty acid profile of the meat. In conclusion, PM showed lower FCR and higher carcass percentage. P1 increased crude protein content of the meat, although it did not significantly affect physical meat quality. P2 improved ADG and carcass percentage of Dorper lambs compared to P1.

Authors: Ramadhani Lusi , Sukma Dina 
Published: December 2024

Aggressive behavior in adolescents, especially in male students, is often influenced by two significant factors: narcisstic and social rejection. This study aims to analyze the contribution of narcissistic tendencies and social rejection experiences to aggressive behavior of male students at State Vocational School 5 Padang. The phenomenon of aggressive behavior is often influenced by psychological and social factors, including narcissistic tendencies and social rejection, which can worsen interactions between students. The sample of this study consisted of 182 male students selected by purposive sampling. The method used was quantitative with a correlational approach, using a questionnaire instrument that measured narcissistic tendencies (NT), experiences of social rejection (ESR), and aggressive behavior (AB). Data analysis showed that narcissistic tendencies have a significant contribution to aggressive behavior, with a fairly high correlation coefficient (r = 0.374, p < 0.05). Meanwhile, social rejection also showed a significant contribution to aggressive behavior (r = 0.507, p < 0.05). A significant contribution between narcissistic tendencies and social rejection (r = 0.524, p<0.05). These findings indicate that students with high narcissistic tendencies and experiences of social rejection tend to be more prone to exhibit aggressive behavior. The importance of psychological and social interventions in the school environment to minimize aggressive behavior and improve students' social relationships. Holistic approach strategies and social support are expected to reduce the negative impact of narcissistic tendencies and experiences of social rejection, thus creating a more conducive learning environment.

Resumo
A caraterização tecno-tipológica das indústrias líticas recolhidas nas sondagens H, Z e N (18 m²) do sítio arqueológico da Cardina-Salto do Boi, no vale do Rio Côa, conjugada com o estudo da gestão das respetivas matérias-primas, permitiu identificar três ocupações do Paleolítico Médio, datadas de (1) ca. 155 ka BP a ca. 80 ka BP, (2) ca. 80 ka BP a 51 ka BP e (3) 51 ka BP a 39 ka BP. Permitiu, também, reconhecer uma sequência de ocupações do Paleolítico Superior, sobrepostas estratigraficamente às do Paleolítico Médio, posteriores a 34 ka BP, bem como mistura de materiais líticos dos dois períodos em unidades estratigráficas das sondagens Z e N, datadas do intervalo compreendido entre 39 ka BP e 34 ka BP.
Dado que o sítio arqueológico da Cardina-Salto do Boi é, até ao momento, o único no Vale do Côa com uma sequência de vestígios da presença humana que vai do MIS 6 (ca. 190 ka BP a ca. 140 ka BP) ao MIS 1 (11,7 ka BP ao presente), o seu estudo revela-se da máxima importância, uma vez que contribui para a compreensão diacrónica da exploração do território por parte do Homem de Neandertal e do Homem Anatomicamente Moderno.

Abstract
The techno-typological characterization of the lithic industries from trenches H, Z, and N (18 m²) from the Cardina-Salto do Boi archaeological site, in the Côa River valley, combined with the study of the lithic resource management, made it possible to identify three Middle Palaeolithic occupations, dating from (1) ca. 155 ka BP to ca. 80 ka BP, (2) ca. 80 ka BP to 51 ka BP, and (3) 51 ka BP to 39 ka BP. It also allowed the recognition of a succession of Upper Paleolithic occupations, after 34 ka BP, stratigraphically overlapping those from the Middle Paleolithic, as well as a mixture of lithic artifacts from both periods in stratigraphic units of the Z and N trenches, dated to the interval between 39 ka BP and 34 ka BP.
Since the Cardina-Salto do Boi archaeological site is, to date, the only one in the Côa Valley with a succession of occupations ranging from MIS 6 (ca. 190 ka BP to ca. 140 ka BP) to MIS 1 (11.7 ka BP to the present), its study proves to be of utmost importance, as it contributes to the understanding of the strategies for exploring the territory carried out by the Neanderthals and Anatomically Modern Humans.

Published: December 2024

This article describes the design and fabrication of an angle tilt adjustment device that automatically adjusts the measured surface to parallel the surface plate. The device features a 150 mm 150 mm worktable and enables independent tilt adjustment of the worktable surface in the X and Y directions via two worm-gear pairs driven by stepper motors. For high angular resolution around the OX and OY axes, the device employs a transmission ratio of 6781 from two motors to these axes. The experimental results reveal that the adjusted average nonparallelism between the measured surface and the surface plate reaches 0.001 mm. The results indicate that the device is fully capable of performing accurate measurements. The device is compact, easy to carry, and low in production cost, making it ideal for installation in small and medium mechanical workshops.

Published: December 2024

The steep rise of cases pertaining to Diabetes Mellitus (DM) condition among global population has encouraged extensive researches on DM, which led to exhaustive accumulation of data related to DM. In this case, data mining and machine learning applications prove to be a powerful tool in transforming data into a meaningful knowledge. Several machine learning tools has shown great promise in diabetes classification. However, challenges remain in obtaining an accurate model suitable for real world application. Most disease risk-prediction modelling are found to be specific to a local population. Besides that, real world data are likely to be complex, incomplete and unorganized making it a challenge to develop models around it. This research aims to develop a robust prediction model for classification of type 2 diabetes mellitus (T2DM), with the interest of a Malaysian population, using several well-known machine learning algorithm such as Decision Tree, Support Vector Machine and NaÃ¯ve Bayers. In order to achieve this, several data pre-processing method is implemented to improve the model performance. The models utilize local based datasets obtain from IIUM medical centre records. Besides that, each models is validated using split and 10 cross fold method. Ultimately, the performance of each model is evaluated and compare based on several statistical metrics that measures the accuracy, precision, sensitivity and efficiency. The final result shows that Random forest model provides the best overall prediction performance in terms of accuracy (0.87), sensitivity (0.9), specificity (0.8), precision (0.9), F1-score (0.9) and AUC value (0.93) (Normal).

Published: December 2024

Herbal medicine has a long history of being for treating various ailments ranging in severity. Traditional medicine is widely used on a regular basis by Sudanese. This research aims to determine the phytochemical constituents and evaluate the antioxidant and antimicrobial activities of the crude extracts from three Sudanese traditional medicinal plants (khella, marula and black mustard). The phytochemicals of the oils were determined by Gas Chromatography Mass Spectrometry (GC-MS). The GC-MS analysis showed that the predominant constituents in the black mustard were 2,4-Decadienal (31.72%), 2-Pyrrolidinone 1-methyl (19.41),phenol (9.43%), Limonene (6.8%), Benzoic acid (2.12%), 2-(1-phenylethyl)- (1.78%), and Eugenol (0.96%). The identified fatty acids were Oleic acid (1.86%) and Palmatic acid (1.34%). The major aromatic components found in the marula extract were Phenol,2,2'-methylenebis[6-(1,1-dimethylethyl)-4-methyl(29.96%),Phenol, 2,4-bis(1,1-dimethylethyl)(1.94%).The major fatty acid present was Linoleic acid (18.51%). The most abundant components found in the khella seed oil were ?-Farnesene (11.8%), Ammidin (5.44%), Methoxsalen (3.62%), Stearic acid (2.81%), Palmitic acid (2.81%), Decanoic acid, propyl ester (1.10%) and Oleic acid (0.81%). To assess the antioxidant activity of the three aqueous extracts, the radical scavenging activity (RSA %) for khella seed extract varied between 21.15 and75.44for all concentrations (125, 250, 500, 1000 µg/ml). At a concentration of 1000 µg/ml, black mustard extract scavenged 46.65% of DPPH radicals, whereas that of 500, 250 and 125µg/ml caused 28.31%, 20.68%, and 19.38% RSA, respectively. The aqueous extract of marula bark had the highest RSA% for all concentrations (98.67% 97.06%, 95.76%, and 80.84%, respectively) compared to the aqueous seed extract for khella and mustard. Antimicrobial activities of different solvents extract of the three medicinal plants studied against three selected microorganisms (E. coli, S. aureusand C. albicans). Ethanolic extract of marula and khella showed the most potent activity against S.aureusand C. albicans. Aqueous and chloroform extracts were failed to inhibit growth for the three strains. The MIC concentrations ranged from 0.37mg/ml to 0.75 mg/ml for both bacteria and fungi.
