Adaptive AI-Driven Microgrid Control for Real Time Integration of Decentralized Renewable Energy in Emerging Industrial Zones
As localized energy systems, microgrids provide a viable way to solve problems with energy dependability and access in rural and isolated locations. These regions often have inadequate and unstable grid infrastructure, which restricts their access to energy. Artificial Intelligence (AI) improves the overall performance, flexibility, and efficiency of microgrid systems. AI ensures a steady and dependable power supply by enabling predictive maintenance, optimal load forecasting, energy storage management, and renewable energy resource optimization. AI may help microgrids anticipate system faults, better control energy consumption, and prolong the life of vital parts. Additionally, AI ensures the sustainability of microgrids in resource-constrained places by optimizing the usage of renewable energy sources like solar and wind. Successful case studies from places like the US, India, and Africa have shown the promise of AI-enhanced microgrids in raising the standard of living for marginalized areas, despite obstacles like data infrastructure and upfront installation costs. Microgrids have a bright future thanks to developments in artificial intelligence (AI), which might increase electricity availability and promote economic growth in rural and isolated regions of the world.

Addition of yattria partially stabilized Zirconia for reinforcement of dental porcelain
The aim of this study was to investigate the effects of addition of Yttria partially stabilized Zirconia powder to dental porcelain being incorporated in 3,5 and 7-percent by weight on some mechanical properties. The measured properties were flexural strength, modulus of elasticity, fracture toughness and hardness. Samples were prepared according to the manufacturers instructions. Zirconia powder was thoroughly mixed with the porcelain powder in the correct weight percent before use. Flexural strength, modulus of elasticity, and fracture toughness were measured using three-point bending test. The hardness was measured using a conventional microhardness tester. All data were collected and analyzed with one-way analysis of variance (ANOVA) and LSD test (p=0.05). The results indicated that the addition of 3 % and 5 % of Yttria partially stabilized Zirconia to the conventional dental porcelain powder resulted in increased flexural strength and fracture toughness of the porcelain. On the contrary, 3 % and 5 % zirconia decreased both the modulus of elasticity and hardness. In addition, 7 % zirconia decreased all tested properties. X-ray examination showed that zirconia addition increased the radiopacity of the material. It was concluded that zirconia-modified dental porcelain was stronger and tougher than the conventional unmodified ceramic.

Adverse health effects, risk perception and pesticide use behavior
The use of pesticides on the farm is largely governed by voluntary behavior. It is important to understand what drives farmer’s behavior of pesticide use. Health belief models in public health and social psychology argue that persons who have had adverse health experiences are likely to undertake greater preventive behavior which is tested here. A survey of 163 farmers was drawn in Vehari and Lodhran district of southern Punjab. Almost all the farmers were found using pesticides extensively and covering their body partially. Resultantly more than 77% farmers experienced at least one health symptom. The analysis appeared to confirm the hypothesis that farmers who have experienced health problems from pesticide use are having heightened concern about health effects of pesticides than farmers who have not experienced such problems. Farmers who report experiencing such problems are also more likely to report using protective clothing than farmers who do not report having such problems. The study however, does not support the hypothesis that farmers who have had experienced health problems from pesticides are likely to use alternative pest management practices. Finally study concludes that to improve practices of pesticide use, specific and relevant information through training programs should be provided to farmers, focusing health and environmental risks of pesticide use.

Amino acid composition of three fresh water fish samples commonly found in south western states of Nigeria
The amino acid components of three fresh water fishes: African catfish (Clarias gariepinus), snake fish (Channa striatus) and tilapia fish (Tilapia zillii) were reported. Among the amino acids investigated, aspartic and glutamic acids were found most abundant in all the three samples with values ranging from 10.4 – 10.7 g/100g crude protein, cp (aspartic acid) and 14.3-14.6 g/100g cp (glutamic acid. The most abundant essential amino acids were Lysine (Leu), Leucine (Leu), and Arginine (Arg). The total acidic and amino acids (TAAA) (24.9 – 25.2g/100g, cp) in all the samples were greater than the total basic amino acids (TBAA) (18.4 – 19.8g/100g, cp) and Leu / Ile ratio values (2.09 – 2.20) showed that Leu > Ile in all the samples. The predicted protein efficiency ratio (P-PER) values (3.46-3.59) were considerably high and this would make them good food complements. The isoelectric point (pI) ranged from 4.68 – 6.04, showing that they are in acidic medium. In essential amino acid scores (based on whole hen’s egg), Lys was highest in all the sample with values ranging from 1.57 – 1.66 and their limiting essential amino acid was Valine (Val). On provisional essential amino acid scoring pattern, Lys (1.77 – 1.87) and Val (0.93) had the highest and lowest scores respectively. Essential amino acid scores based on pattern for pre-school children showed that all the samples would supply the required essential amino acids for pre-school children (2 – 5 years old). Generally, the samples are good sources of essential amino acids.

Application of Nanotechnology in Pharmaceutical Product Development
Bioavailability (with high permeability and solubility) is important for effective therapeutic drugs. Nevertheless, in drug research, many drug molecules are of low permeability and solubility. Accordingly, in order to prolong the release and boost the bioavailability of these drug substances, new methods are required. A nanoparticle is a new solution to frame drug agents into nanoparticles. Two drugs fragments like furosemide (diuretic) suit to the BCS class IV and Amlodipine Besylate (calcium channel blocker) suit to the BCS class II in this study were co-encapsulated into PLGA nanoparticles by PVA as a surfactant. Normal particle dimension of these nanoparticles was found to be 275 nm with -12 mV zeta potential value. In house HPLC technique was developed for simultaneous estimation of these two molecules using CAN 5 C18-AR HPLC column with Phosphate buffer: CAN (62:38) as a mobile phase (1.0ml/min flow rate, 220nm detection) for entrapment efficacy study. Normal entrapment efficiency of Amlodipine and Furosemide were found to be 40% and 58%. Additionally, in vitro dissolution study was conducted in the phosphate buffer pH 7.4, and it was witnessed that 6% and 10% amlodipine and furosemide were released after 24 hours at room temperature condition at 100 rmp. From these results, it was concluded that these two molecules could be co-encapsulated in PLGA nanoparticles and below 15% relief of these two molecules after co-encapsulation in the PLGA nanoparticles showed the controlled release arrangement.
