Nghiên cứu được triển khai với 2 thí nghiệm nhằm xác định tỷ lệ cho ăn phù hợp ở giai đoạn nuôi ốc hương thương phẩm. Mỗi thí nghiệm với 3 lần lặp lại với 4 mức tỷ lệ cho ăn thức ăn công nghiệp (1, 2, 4, và 6%) hoặc thức ăn tươi (3, 6, 9, và 12%) theo phương pháp ngẫu nhiên hoàn toàn. Kích cỡ ốc khi bắt đầu thí nghiệm có khối lượng và chiều cao tương ứng là 3,3 ± 0,01 g và 2,2 ± 0,03 cm Kết quả cho thấy, sinh trưởng của ốc hương bị ảnh hưởng bởi tỷ lệ cho ăn (p<0,05), cụ thể: Đối với thức ăn tươi, tỷ lệ cho ăn càng cao tốc độ sinh trưởng của ốc càng cao, khối lượng ốc khi thu hoạch đạt cao nhất ở tỷ lệ cho ăn 9% hoặc 12% tương ứng với 6,45 g/con hoặc 6,12 g/con, thấp nhất ở nghiệm thức cho ăn với tỷ lệ 3%, chỉ đạt 4,91 g/con. Ngược lại, tỷ lệ cho ăn thức ăn công nghiệp càng cao thì sinh trưởng của ốc có xu hướng giảm, tốt nhất ở mức cho ăn 2% khối lượng thân/ngày. Tỷ lệ cho ăn càng cao thì hệ số thức ăn càng cao (p<0,05). Tỷ lệ sống của ốc không bị ảnh hưởng bởi tỷ lệ cho ăn (p > 0,05) thức ăn công nghiệp hay thức ăn tươi, tất cả các nghiệm thức ở cả 2 thí nghiệm đều đạt >72%. Các yếu tố môi trường nước liên quan đến ni tơ và phốt pho tăng dần theo tỷ lệ cho ăn, và có sự sai khác có ý nghĩa thống kê giữa các mức cho ăn thức ăn tươi hay thức ăn công nghiệp (p<0,05). Áp dụng phương pháp phân tích phương trình hồi quy đa thức bậc hai của các thông số tăng trưởng (%) và tỷ lệ cho ăn (%) đã xác định được tỷ lệ cho ăn tối ưu cho sự tăng trưởng tốt nhất của ốc hương đối với thức ăn công nghiệp là 1,53% và thức ăn tươi là 10,8%.

ZnO nanorod thin films doped with cobalt were successfully synthesized on Indium Thin Oxide (ITO) glass substrates using the chemical bath deposition method to assess their characteristics and methylene blue degradation capabilities. ZnO nanorod thin films doped with cobalt were successfully synthesized on Indium ThinOxide (ITO) glass substrates using the chemical bath deposition method to evaluate their characteristics and methylene blue degradation capabilities. This study compared undoped and Co-doped ZnO on ITO glass substrates for photoelectrocatalytic (PEC) applications. XRD analysis confirmed that all samples exhibited a crystalline hexagonal wurtzite structure, with no additional phases detected in films with 5 % Co doping. The formation of nanorod structures in both undoped and Co-doped ZnO was revealed by SEM images where the presence of Co in the doped ZnO was confirmed through EDX analysis UV-DRS analysis indicated changes in band gap values with the addition of 5 % Co doping, decreasing from 3.09 to 3.07 eV for the ZnO/ITO and Co-ZnO/ITO photoanode. Evaluation of the PEC performance of the photoanodes toward methylene blue in an aqueous solution showed that Co doping enhanced the PEC efficiency of the ZnO/ITO photoanode. The decolourization efficiency of methylene blue reached 93.72 % using Co-ZnO/ITO, which is higher than that of ZnO/ITO at 86.84 %. Furthermore, the kinetic study showed that Co-ZnO/ITO photoanode follows a first-order reaction kinetics model with a reaction rate constant of 0.0085 min−1. The result of our study suggests the potential of Co-ZnO/ITO photoanode in addressing dyecontamination issues effectively.

Published: December 2024

In numerous engineering foundation designs, the influence of lateral loads is frequently underestimated in calculations. Consequently, recent studies have increasingly concentrated on comprehending the behavior of soil and foundations when subjected to lateral load influences. The present study aims to examine the performance of ring foundations, a common engineering solution employed in the construction of tall and slender structures that are vulnerable to lateral loads, such as those exerted by wind forces. The objective of this study is to enhance the lateral resistance of ring foundations by incorporating skirt foundations. The efficacy of skirt foundations was evaluated through a series of tests conducted on sandy soils of varying densities, ranging from dense to medium loose sand. Subsequently, lateral loads were applied to the ring foundations, both with and without skirt foundations. The results demonstrated that the lateral resistance increased in proportion to the ratio between the inner and outer diameters. Furthermore, the improvement rate was enhanced by the addition of the skirt foundation. Additionally, the lateral resistance increased with increasing the skirt foundation depth, reaching a maximum of approximately 50-100%. Similarly, an increase in the skirt inclination ratio to 450 resulted in a lateral resistance increase of up to 650%.

Authors: Salman Abdulhakeem Amer 
Published: December 2024

The wear behavior of Aluminum Alloy (AA) 2024 reinforced with SiC particles were investigated at room conditions. Stir casting method was used to prepare the matrix composite of AA 2024 alloy reinforced with different weight percentages of SiC (3, 6, 9, 12 wt%). The wear behavior of both AA 2024 and AA 2024/SiC composite was studied using the reciprocating wear test. Loads of 2.5, 5, 7.5, 10, and 12.5 N were applied with sliding speeds of .0.55, 0.72, 0.88, 1.04 and 1.2 m/sec in dry sliding contact conditions. The microstructure and phase distribution were investigated using Optical Microscope (OM) and Scanning Electron Microscopy (SEM). The results demonstrate the presence of fine dendritic structure with semi-homogeneously distributed SiC particles in the alloy matrix. The micro-hardness increased with increasing SiC percentage. The highest value of hardness of 79.3 HV was found at 12 wt% SiC, from the initial 44 HV of the base alloy. The wear tests showed that the wear rate increased with increasing applied normal contact load at a contact sliding speed of 0.88 m/sec. The wear rate of the as cast material was 18.59 ×10-8 g/cm. Adding the SiC particles decreased the wear rate to 13.78, 9.76, 7.98, and 5.81 ×10-8 g/cm for 3, 6, 9, 12 wt% SiC addition at 12.5 N applied load, respectively. SEM examination of worn surfaces showed that severe and abrasive wear was exhibited at higher loads in the dry case while mild and adhesive wear were observed at lower loads in the lubricated condition.

Published: December 2024

This study employed the AMPS-1D software to investigate the relationship between the open-circuit voltage (Voc) and the energy difference between the Highest Occupied Molecular Orbital (HOMO) of the donor and the Lowest Unoccupied Molecular Orbital (LUMO) of the acceptor in P3HT:PCBM bulk heterojunction organic solar cells. The findings indicate a correlation between Voc and the HOMO-LUMO offset up to 1.1 eV, after which Voc remains constant. This behavior is further elucidated using a theorem based on the quasi-Fermi level, which predicts a Voc of 0.64 V, in good agreement with our simulation result of 0.68 V. The Power Conversion Efficiency (PCE) of the solar cell was studied with respect to the active layer thickness, demonstrating an increase in PCE up to 0.40 μm followed by a decrease, yielding a maximum PCE of 5.023%, consistent with the literature. The effect of temperature on PCE was also examined, demonstrating an increase in PCE with decreasing temperature in the range of 150–320 K, with a performance of 6.371% at 150 K. Furthermore, the impact of the optical bandgap on PCE was explored, showing that the PCE increased with a decrease in the optical bandgap of the P3HT:PCBM solar cell, reaching 9.94% when the optical bandgap was 1.5 eV. These findings provide valuable insights into the optimization of the performance of organic solar cells by manipulating key parameters, such as the HOMO-LUMO offset, active layer thickness, temperature, and optical bandgap.
A Study of the Influence of Additives of Nanostructured Functional Ceramics in the Coating of Welding Electrodes on their Welding and Technological Properties
Authors: Saidov Rustam , Rakhimov Rustam , Touileb Kamel , Abduraimov Sanjar 
Published: December 2024

The present work aims to study the influence of Nanostructured Functional Ceramics Photocatalysts (PNFC) under the brand name ZB-2, obtained using a synthesis method deploying pulsed radiation activation technology on welding and technological properties. This method of obtaining ceramic material allows the latter to be produced on an industrial scale. Therefore, it can replace the technology for producing PNFC under the influence of concentrated solar radiation at the Big Solar Furnace (BSF) of the Institute of Materials Science, Academy of Sciences of the Republic of Uzbekistan. The ZB-2 ceramic material has shown its effectiveness when used as an additive in the coating charge of the MR-3 welding electrode. Thus, the breaking arc length of the MR-3 welding electrode is increased up to 2% with the addition of ZB-2 to the coating charge. With additions of more than 2%, the breaking arc length decreases. The additive ZB-2 has the same effect on the diameter of the deposited point of the MP-3 welding electrode. When its content in the coating is up to 2%, the diameter of the deposited point increases, and a further increase in the additive content reduces this indicator. Adding up to 1% ZB-2 into the coating composition has a beneficial effect on the size of the peak at the end of the electrode. When its content exceeds 1%, the latter decreases. Also, an increase in the content of the PNFC additive in the coating of the MR-3 electrode reduces the value of the melting coefficient and increases the value of the deposition coefficient, which contributes to a sharp reduction in losses due to waste and spattering up to 53% when the additive content in the coating mass is up to 8%.

Low environmental temperature alters behaviour and physiologic responses leading to low productivity in poultry. This study was designed to evaluate the effect of orally administered aqueous crude extracts of Persea americana and Tamarindus indica in broiler chickens during cold season. Twenty-eight, 3-week old Arbor acres mixed sex broiler chickens were used. Seven broiler chickens were assigned each to Cg (control), TA (20% avocado aqueous extract), TB (20% aqueous tamarind extract) and TC (20% aqueous avocado extract + 20% aqueous tamarind extract). The treatmentswere administered as sole drinking water while the control received plain water. Thermal environmental data during the study period were measured, using a dry and wet bulb thermometer and relative humidity using a table, while the temperature humidity index was calculated. Cloacal temperature and blood samples were collected on days 28, 35 and 42 of the experimental periods. The Results show that the experimental period was thermally stressful (cold stress). Mean cloacal temperatures of broiler chickens in all the treatment groups were significantly (P < 0.05) higher (41.0 - 42.3°C) than those in control group (41.0 – 41.4°C) on days 28, 35 and 42. The heterophil/Lymphocyte ratio, pack cell volume, heamoglobin, total protein, total white blood cell, total red blood cell, weight gained were higher (P > 0.05) in treatment groups compared to control group. It was concluded that aqueous extracts of Persea americana and Tamarindus indica singly or in combination ameliorated cold-stress and improved broiler performance during cold-dry season

The influence of diets containing graded levels of tiger nut (Cyperus esculentus L) on feed intake, yield and total solids content of milk of Red Sokoto goat were evaluated in this study using four does in their mid-lactation stage. The does were fed diets (A, B, C and D) containing 0, 10, 20 and 30% tiger nut (TGN) in a 4x4 Latin Square arrangement. Feed intake and milk yield were measured daily and the milk samples were also analyzed for total solids (%). The results showed that feed intake and milk yield of goats that were fed 10% and 20% tiger nut diets were higher (P<0.05) than those fed 0% and 30% tiger nut diets (P<0.05). Total solids (%) of milk was not influenced by inclusion of tiger nutin the diets (P>0.05). It was therefore concluded that up to 20% inclusion level tiger nut can be made in the diet of lactating does to improve milk production

Published: December 2024

In aquaculture nutrition experiments, mortality is inevitable as the experiment progresses. Thus feed consumed by live and dead fish may errorneously be assumed as feed consumed by live fish. This error manifests when measuring feed intake as a component of nutrient utilization parameters. In order to accurately evaluate feed intake with due consideration of mortality encountered during aquaculturenutrition experiment, a model was developed which is:
Total feed consumed by number of survived fish = Where D = Number of
Days fish were fed within each period before it is adjusted (e.g fortnight), it is constant throught period of experiment. F = Quantity of feed fed per day for a fortnight before the quantity is adjusted, it changes every fortnight. L = Number of Live fish at the end of experimental period. N = Number of fish at each weighing period, it may change every fortnight or may be constant if no mortality occurred. While n = Number of times fish were weighed and quantity of feed was adjusted but this does not include the final weighing at the termination of experiment. However, if the fish were weighed weekly, then D = 6.

Authors: POPOOLA M. A. , OSENI S. O. 
Published: December 2024

The study aimed at classifying Nigerian indigenous rams on the basis of their head conformation using multivariate analyses. Twelve cephalic traits or 1,200 rams belonging to four breeds (Balami, Yankasa, Uda and WAD) were measured. The traits were subjected to principal component analysis to reduce data dimensionality. A discriminant canonical analysis was. also applied to differentiate between the breeds. The cephalic index reveals that the ram breeds are brachyprosopic except Uda which is mesocephalic breed. The first principal component (PC) had variables related to length and diameter amplitudes and explained 37.5 percent of the variance. The second PC gave major relevance to skull, face and neck lengths of the rams and contributed to 21.30 percent of the total variance. while the third PC loaded highly for skull length, head depth and neck length and contributed 17.35 percent of the total variance. The stepwise discriminant analysis revealed that skull width, head width, head length and head depth were the most discriminating variables to separate the four breeds of rams.

Sesame is one of the agricultural product that is readily available cheap and can be used to reduce cost of livestock feed. A total of 150day old broiler chicks of relatively the same was rand01nly allotted to five dietary treatment replicated three times with ten chicks per replicate. The experimental design was completely randomized design (CRD). Five diets were formulated to contain different levels of sun-cured sesame meal at 0%, 10%, 20%, 30% and 40%. At the end of eight week two birds per replicate was slaughtered for carcass characteristics. Treatment on carcass characteristics (live weight, bled weight, eviscerated weight. dressing weight, drumstick, and breast) were not significant. However. variations in organs (liver and gizzard) were significant with birds on T2 (20%) having the highest liver weight of 63 compared to 42 observed birds reared on T1 (0%). The gizzard increased significantly for birds on treatment 4 (30%,) compared to 50 tor those on Tl (0%) blood was collected from two birds per replicate and analysed for haematological indices. The supplementation of broilers diet effected a significant (p<0.05) variations in the haematological parameters. Birds reared on T4 (40% supplementation) had the least significant value of 19.0% in the PVC concentration compared to its counterpart on Tl (0%) with mean value of 32.0%. The RBC value varied from 4.04mm x 106 for birds on Tl to 3.36mm x recorded for birds on T4. Apparent variations in the values 2.17 — 3.17 observed with eosinophil and haemoglobins 6.02 — 7.68g/dl were not significant. In conclusion, sun-cured sesame meal could be added to broiler chicken ration at 40% without any adverse
