Ensayo potencial de dos algas verdes Ulva lactuca y Ulva intestinalis como biofertilizantes T2 - Sustainability, Agri, Food and Environmental Research N2 - In recent years, development has been witnessed in the market expansion of agricultural inputs and products including substances and materials that improve the functioning of the soil, plants, and the interactions between soil and plant. This is a very broad category of products and substances that often bring innovative solutions in the field of fertilization and crop protection. The objective of this study is to improve the production of the market garden where tomato plants in nurseries from powders of two green algae Ulva lactuca and Ulva intestinalis, harvested as biofertilizers in the west coast of Mostaganem province at North-Western Algeria. They have minimal effects on the environment, including soil, subterranean water, river, and estuary ecosystems such as the Cheliff river, biodiversity, and global warming. The experimental part was carried out following the method of extraction of algae and used as a biofertilizer on the tomato to its simplicity and accuracy, which is the subject of the study of the germination, growth, and the development of young plants. The results show that the powders obtained from the Ulva lactuca algae and used as biofertilizers are the most suitable to increase the growth of plants in the case of tomato in our study, which means a remarkable increase in stem length by compared to the other treatments with averages of 17.75 cm, 16 cm length of stem/plant, while the other treatments (Enteromorpha intestinalis, mixture, and reference) gave 14.75; 13.87; 13.65 cm length of stem/plant.

The influence of the IQ crosstalk RF impairment on the performance is analyzed for different vector summation implementations, guiding to the VMPS architecture choice and design optimization. The chosen architecture consists of an IQ analog-controlled voltage-gain amplifier (IQ-VGA), Branchline coupler, and a Wilkinson combiner. Test structures for the variable-gain amplifier (VGA) and the VMPS are manufactured and measured in a 130-nm BiCMOS technology ( fT/fmax = 300/500 GHz). For the phase resolution of 11.25°, the VMPS achieves an average rms PE and AE of 1.2° and 0.35 dB, respectively, with equivalent to 5.5 -bits control voltage across the frequency band 220–260 GHz. The VMPS consumes 60 mW from 2.5-V supply and occupies 0.2 mm2 of silicon area. This work presents the least PE and AE across a wide bandwidth for VMPS in silicon technologies above 200 GHz, which is crucial for large-scale beam-steering arrays.

In this study, the flow structures within the vortex tube were examined qualitatively. The examination considered both compressible and incompressible fluids, using pressurized air and water as working fluids. A parametric study was conducted, in which the fluid inlet pressure and the vortex tube length were varied. Three tubes, with the same diameter but differing lengths (100, 180, and 240 mm) were utilized. The flow inside the tube was investigated using a flow visualization technique, which was employed in a variety of configurations and setups contingent on the specific fluid conditions under examination. The visualization process required the use of aerosol injection in the case of air, and kalliroscope particles in the case of water investigation. The research enabled the visualization of the flow structure within the vortex tube, thereby significantly advancing the comprehension of the underlying physical processes. The findings of the experimental research demonstrated the existence of phenomena of considerable scientific value. The internal vortex and its spatial and temporal structure observed in the RHVT were consistent with literature data. This was achieved despite the so-far established consensus that this type of research is challenging and not entirely reliable. In the course of water-based investigation, the cavitation phenomenon was observed in the vicinity of the internal vortex. This discovery is likely to be the first of its kind and may contribute significantly to the advancement of research on the Ranque–Hilsch phenomenon.
