Summary: The study is important for reducing energy consumption during the process of cutting sunflower stalks by selecting an optimal knife profile. The research compared the cutting forces of the proposed knife system with other known systems, and found that using a curved spiral design for the retaining and main knives significantly reduced cutting forces. Moreover, the cutting force of the proposed design remained unchanged when the stem was removed from the axis of rotation, eliminating the need for additional energy costs.

Summary: Two experiments were conducted to measure the apparent and standardized ileal digestibilities (AID and SID) of amino acid (AA) of corn, wheat, soybean meal (SBM), and corn glutenmeal (CGM) in growing Japanese quail. The results showed that AID of certain amino acids increased as the birds aged, while AID of other amino acids decreased in younger quails. The study suggests that the digestibility of indispensable amino acids should be adjusted for age classes in Japanese quail during the growing period.

Summary: Logging and sawing of timber using conventional tools in Nepal has caused significant damage to valuable timber, residual stand, regeneration, and forest soil. This study aimed to quantify timber losses and identify strategies to reduce them in the Terai Shorea robusta forest. The results showed significant losses in both tree felling and log sawing stages, mainly due to the use of inappropriate equipment. The use of synthetic ropes for directional felling and skidding, as well as flexible and portable sawing machines, were recommended as strategies to reduce timber losses.

Summary: A series of experiments were conducted to determine the phosphorus digestibility in different grains and protein meals for growing Japanese quail. The results showed differences in phosphorus digestibility among different ingredients, with young quail exhibiting higher contribution of endogenous phosphorus when fed with wheat. This study highlights the importance of correcting Apparent Ileal Phosphorus Digestibility (AIDP) and implementing Standardized Ileal Phosphorus Digestibility (SIDP) coefficients in feed formulation.

Summary: This report introduces a spherical fleece made of wool fibers and single-walled carbon nanotubes (SWCNTs), which can generate repetitive electrical currents in all directions. The fleece can change the surface area available for ions to access SWCNTs, leading to a piezoionic phenomenon. The fabricated SWCNT/wool energy harvester has the highest current per input mechanical stress among all reported underwater mechanical energy harvesters to date, and it is suitable for low-frequency environments, making it ideal for utilizing natural forces as harvesting sources.

Summary: Logging in the Amazon biome, the largest tropical forest in the world, continues every year, causing significant impacts on the residual forest, wildlife, and streams. This review examines the current state of research on logging impacts in the Amazonia and finds that logging intensity and cycle play crucial roles in determining the extent of damage. Lowering logging intensity and implementing longer logging cycles are suggested for sustainable forest management in the region.

Summary: This study investigates the effects of cutting electrical steel laminations using abrasive water jet (AWJ) and wire electrical discharge machining (WEDM) techniques on the efficiency and magnetic losses of a 5.5 kW induction motor. The results show that AWJ cutting leads to burr formation while WEDM cutting results in recast layer formation. Both cutting methods result in decreased efficiency and increased magnetic losses with increasing frequency and motor loading rate. The optimum results, determined using Response Surface Methodology (RSM), are achieved at a frequency of 50 Hz and a motor loading rate of 100% in both cutting methods. Analysis of variance (ANOVA) reveals the statistical effects of frequency and motor loading rate on efficiency and magnetic losses.

Summary: With the development of autonomous/smart technologies and the Internet of Things, wireless sensor nodes play a vital role in intelligent mechanical engineering. However, traditional power supply methods face challenges such as layout difficulties and environmental pollution. Therefore, it is crucial to harvest mechanical vibration energy using technologies like the triboelectric nanogenerator to provide in situ power supply for these nodes. This review systematically reviews recent achievements and discusses challenges and development orientation for mechanical vibration energy harvesting based on TENG, which will contribute to the future development of intelligent mechanical engineering in the era of IoT.

Summary: Due to the high milk production of Holstein cows, many countries import semen to improve local dairy herds. The strategy would be more effective if the environment conditions during bull selection were the same as those in which the semen is used. Failure to consider the genotype by environment interaction may result in variation in estimated breeding values, potentially reducing selection response.

Summary: The aim of this study was to evaluate the impact of successive heat waves on the thermoregulation and hormonal responses of non-pregnant and pregnant ewes. Weather variables and physiological variables were measured, including rectal and tympanic temperatures, respiratory rate, and serum levels of triiodothyronine (T3) and prolactin. The results showed that physiological variables were higher under heat wave conditions, with core body and tympanic temperatures being affected by changes in air temperature. However, T3 and prolactin levels were not influenced by heat waves, and rectal temperature and respiratory rate were highest in non-pregnant ewes. Overall, the Santa Ines breed demonstrated the ability to tolerate heat waves without severe signs of thermal stress.

Summary: Traditionally, breeding values are estimated using the numerator relationship matrix, but with genomic information, markers can be included for more accurate estimation. This study compared different methods for estimating breeding values in a broiler population, using various densities of SNP and whole-genome sequence data. Results showed that using 10% of the high-density array can yield unbiased and accurate breeding values.

Summary: Genomic tools, such as genome-wide association studies (GWAS), can aid in selecting animals genetically resistant to heat stress. This study compared the variance explained by SNPs and direct genomic breeding values (DGVs) at two temperature and humidity index (THI) levels. Using records from Holstein cows, the GWAS results showed minimal differences in SNPs and explained variances between the two THI levels. The study recommends further research with a larger number of animals and at more extreme THI levels.

Summary: The aim of this study was to evaluate the feed quality of reconstituted corn grain silage (RCGS) treated with chemical additives and stored for different lengths of time. The results showed that increasing the storage time from 15 to 60 days improved the starch and dry matter degradability of the RCGS. The additive Mycoflake increased the availability of nutrients, and polysorbate 80 showed potential as an antimicrobial agent in silages.

Summary: This study evaluated the impact of different lipid sources on gene expression in porcine skeletal muscle tissue using RNA-Seq, and identified differentially expressed genes involved in metabolic pathways and biological processes. Addition of fish oil in pig diets resulted in intramuscular lipid with a higher composition of certain fatty acids. Blood parameters showed lower cholesterol and HDL content in the fish oil group compared to the other two groups. Enrichment analysis revealed differentially expressed genes related to lipid metabolism, metabolic diseases, and inflammation, as well as specific gene functions and altered blood parameters in each group.

Summary: In this study, we investigated the influence of epigenetic repression, specifically H3K27me3, on gene expression in muscle cells and its impact on mineral content. Using computational methods, we predicted regulatory genes that might be affected by repressive epigenetic regulation related to mineral concentration. Our findings suggest a link between histone modification, gene expression, and mineral content in beef samples.

Summary: The addition of sodium nitrite and hexamine as an additive in guinea grass silage had a significant impact on fermentation and chemical composition. The maturity stage of the grass also interacted with the additive dose in influencing silage traits. The study concludes that the application of the additive at a regular dose effectively restricts the development of undesirable microorganisms and reduces dry matter losses during fermentation.
