We designed a 2.4-7GHz dual-band microstrip patch antenna DB-MPA using electromagnetic field simulation and transmission characteristic (S21) measurements. Optimizing the slot length of the patch surface increased the directional antenna gain at 7 GHz by 3.5 dB compared to 2.48 GHz, reducing the effect of the higher spatial propagation loss of 9 dB at 7 GHz. A transmission system simulation with an antenna component model incorporating S21 data measured with the 2.4-7GHz DB-MPA from 1 to 8 GHz was conducted at a spatial propagation distance of 5 to 40 m to verify the practicality of the 2.4-7GHz DB-MPA.

The objective of this work is to explore the contribution of chemistry didactics in the teaching-learning of this subject in students with cognitive disabilities. It is a documentary work that aims to know what are the lines of research in which the publications found are framed and that relate the teaching of chemistry with inclusion, specifically for this population. To classify the documents found, the one suggested by Carriazo and Saavedra (2004) is taken as a basis. It should be noted that the results found are few.

Keywords: Chemistry teaching, inclusive education, inclusion.

This article examines the impact of implementing a solar irrigation system on livestock production in North Cameroon, a region marked by climatic challenges and increasingly dry conditions with 600 to 1,200 mm of rainfall per year and temperatures between 30°C and 40°C. Livestock farmers in the region rely heavily on natural pastures and forage crops to feed their livestock, but these resources are insufficient during periods of drought. The area is home to around 2 million head of cattle, with an estimated 500,000 to 700,000 head of sheep and 300,000 to 500,000 head of goats. Our methodology involved a comparative before-and-after analysis, where data on crop yields, pasture quality and animal performance were collected.....

The Adjin lagoon was studied in its morphological, hydrological and sedimentological aspect. This study made it possible to understand the morphological modifications of the bottom and surface of the Adjin lagoon based on the production and superposition of two bathymetric maps from the years 2008 and 2018. In addition, this study makes it possible to know the estimation of the speed, volume of sediments eroded and deposited. From a morphological point of view, the Adjin lagoon is characterized by depressions and shoals. The depressions are at the origin of the formation of "V" shaped channels. Shoals are characteristic of "U" shaped channels. Depths less than 11 m occupy 2/3 of its surface area........

The article analyzes the supersonic techniques for separating impurities from natural gas extracted from Romanian deposits. One of the newest techniques used in separating water from natural gas is their treatment in a supersonic flow (flow field) using a device (the supersonic separator). The article describt this technique of separating water (the dewatering process) and condensate (the separation petroleum liquid process), which is increasingly used (especially in the limited spaces of offshore platforms).

Keywords: Water, Supersonic. Separation, Natural gas.

Biofuels, derived from renewable organic materials, present a critical opportunity to reduce reliance on fossil fuels and mitigate the environmental consequences of greenhouse gas emissions. As global energy demands grow and climate change intensifies, the need for sustainable energy alternatives has become urgent. This paper examines the potential of biofuels to bridge the gap to a greener energy future, exploring their role as substitutes for fossil fuels and their ability to significantly reduce carbon emissions. While biofuels offer substantial environmental benefits, their production faces challenges, including high costs, competition........

The physicochemical studies of homoeopathic medicines provide better understanding regarding the presence and mechanism of their action in ultra-dilutions. The physicochemical behaviour of glycerol dilutions homoeopathic dilutions has been investigated from the measurements of densities, , ultrasonic speeds, u and viscosities,  of pure ethanol control (91% ethanol in water) and 33 dilutions of glycerol dilutions of potencies ranging from 1C to 200C at ambient temperatures and atmospheric pressure. From the experimental data, a number of physicochemical parameters, viz., the isentropic compressibilities, s, intermolecular free length, Lf, acoustic impedance, Z, relative association......

This study presents the Compressive & Flexural Strength performance of Low-weight Engineered Timber Slab(ETS) composed of wood adhesive, Saw dust, & crack filler. It provides empirical data on the flexural and compressive properties of engineered timber slab(ETS), which is an element of wood adhesive(WA), sawdust(SD), crack filler(CF). SD gave values of 562.3/m3, 0.67, 39.66%, 2.85, 1.2 and 2.98 for mean bulk density, mean specific gravity, mean water absorption, finess modulus, coefficient of curvature (Cc) and uniformity (Cu). Batching was done by volume by virtue of the low density of the component materials (SD & CF). The component materials were manually mixed. A total of twelve (12) cubes of size 150 x 150 x 150mm.........

In order to investigate the pressure fluctuation characteristics of centrifugal pumps under shut-off
conditions, a numerical calculation was carried out using Fluent software based on the RNG k-ε turbulence model. The pressure fluctuation characteristics within the volute and impeller flow fields of the centrifugal pump under shut-off conditions were analyzed, and the shut-off head was predicted. The results show that the monitoring points within the volute flow passage exhibit obvious periodic patterns, and their peak pressure fluctuations occur at frequencies that are multiples of the vane passing frequency. Additionally, the closer the monitoring point is to the volute tongue, the greater the amplitude of pressure fluctuation. Furthermore, for monitoring points located on the centerline of the impeller flow passage, the closer they are to the impeller exit,
the greater the amplitude of pressure fluctuation.
