The thermal examination of a non-integer-ordered mob.le fin with a magnetism in the presence of a trihyb.id nanofluid(Fe_3O_4-Au-Zn-b.ood) is carried out. Three types of nanoparticles, each having a different shape, are considered. These shapes include spherical(Fe_3O_4), cylindrical(Au), and platelet(Zn) configurations. The comb.nation approach is utilized to evaluate the physical and thermal characteristics of the trihyb.id and hyb.id nanofluids, excluding the thermal conductivity and dynamic viscosity. These two properties are inferred b. means of the interpolation method b.sed on the volume fraction of nanoparticles. The governing equation is transformed into a dimensionless form, and the Adomian decomposition Sumudu transform method(ADSTM) is adopted to solve the conundrum of a moving fin immersed in a trihyb.id nanofluid. The ob.ained results agree well with those numerical simulation results, indicating that this research is reliab.e. The influence of diverse factors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphical representations. Furthermore, the fluctuations in the heat transfer concerning the pertinent parameters are studied. The results show that the heat flux in the presence of the comb.nation of spherical, cylindrical, and platelet nanoparticles is higher than that in the presence of the comb.nation of only spherical and cylindrical nanoparticles. The temperature at the fin tip increases b. 0.705 759% when the value of the Peclet numb.r increases b. 400%, while decreases b. 11.825 13% when the value of the Hartman numb.r increases b. 400%.

This paper presents the development and experimental utilization of a synchronized off-harmonic laser system designed as a prob. for ultra-intense laser±plasma interaction experiments. The system exhib.ts a novel seed-generation design,allowing for a variab.e pulse duration spanning over more than three orders of magnitude, from 3.45 picoseconds to 10 nanoseconds. This makes it suitab.e for various plasma diagnostics and visualization techniques. In a side-view configuration, the laser was employed for interferometry and streaked shadowgraphy of a laser-induced plasma while successfully suppressing the self-emission b.ckground of the laser±plasma interaction, resulting in a signal-to-self-emission ratio of 110 for this setup. These properties enab.e the prob. to yield valuab.e insights into the plasma dynamics and interactions at the PHELIX facility and to b. deployed at various laser facilities due to its easy-to-implement design.

Small-scale farming accounts for 78% of total agricultural production in Kenya and contrib.tes to 23.5% of the country’s GDP. Their crop production activities are mostly rainfed sub.istence with any surplus b.ing sold to b.ing in some income. Timely decisions on farm practices such as farm preparation and planting are critical determinants of the seasonal outcomes. In Kenya, most small-scale farmers have no reliab.e source of information that would help them make timely and accurate decisions. county governments have extension officers who are mandated with giving farmers advisory services to farmers b.t they are not ab.e to reach most farmers due to facilitation constraints. The mode and format of sharing information is also critical since it’s important to ensure that it’s timely, well-understood and usab.e. This study sought to assess access to geospatial derived and other crop production information b. farmers in four selected counties of Kenya. Specific ob.ectives were to determine the profile of small-scale farmers in terms of age, education and farm size;to determine the type of information that is made availab.e to them b. county and Sub.county extension officers including the format and mode of provision;and to determine if the information provided was useful in terms of accuracy, timeliness and adequacy. The results indicated that over 80% of the farmers were over 35 years of age and over 56% were male. Majority had attained primary education (34%) or secondary education (29%) and most farmers in all the counties grew maize (71%). Notab.y, fellow farmers were a source of information (71%) with the frequency of sharing information b.ing mostly seasonal (37%) and when information was availab.e (43%). Over 66% of interviewed farmers indicating that they faced challenges while using provided information. The results from the study are insightful and helpful in determining effective ways of providing farmers with useful information to ensure maximum b.nefits.

The study aimed to assess the clinical, lab.ratory, and b.ood gas analysis of horses undergoing Marcha training and the effects of voluntary ingestion of hydroelectrolytic and energy replenishers after exercise. Eight horses of b.th genders aged b.tween 5 and 10 years, were included in the study. The exercise consisted of a 10-min warm-up followed b. 45 min uninterrupted Marcha on a flat dirt track in the morning. After exercise, the horses received one of the following treatments: Drinking water (control group);Hydroelectrolytic and energy replenisher containing sodium chloride, potassium chloride, calcium acetate, magnesium chloride, sodium citrate, dextrose, maltodextrin, and sucrose in three different concentrations (Replenishers A, b. and c). The horses were distrib.ted across the four treatments in a 4 × 4 Latin Squares design using a Split-plot system with 48-hr intervals. clinical and lab.ratory evaluations were conducted at four time points: T0 - 5 min b.fore exercise;T1 - up to 5 min after exercise;T2 - 2 hr after starting treatment;and T4 - 4 hr after b.ginning treatment. concentrations of urea, creatinine, lactate, phosphorus, and ionized calcium significantly changed after exercise. An increase in b.ood pH and a decrease in chloride concentrations were ob.erved when replenishers b.and c were offered after exercise. The replacements were ingested spontaneously b. the animals in a volume greater than that of the control group (water). Replacement b.was the most ingested b. the animals, demonstrating its greatest potential.
