Bijay_Kumar Sharma — Fri, 20 Mar 2026 00:00:00 +0000

51 Pegassi b is the first exoplanet to be discovered in the history of astronomy and astrophysics. This is a hot Jupiter trapped in a subsynchronous orbit . In 2Gy it has spiraled from aG1, first Clarke’s Orbit at 0.06344AU, to the present orbit at aexo = 0.0530025AU .Setting up the star and exo-planet in primary centric framework we get the theoretical = 0.19128 and observed = 4.23 d21.9 d = 0.193151 almost coincident within error bars . This implies that equation is correctly set up. The exponent Q = 2.7251in radial velocity expression is obtained from Mean Motion Resonance =2 considerations and by setting up the transit time from aG1 to the current semi-major axis aexo in 2Gy (the age of 51Peg b system) the structure constant is obtained as K = 21051. Once Q and K are determined the Transit Time integral is correctly set up. Using this transit time set up , at four check points within the current semi-major axis the transit time is calculated by the Kinematic Model developed by the Author and by the Seismic Model currently being used by the scientific community. The seismic model gives a conservative estimate of the transit times.The Roche’s limit 4.34109m= 0.029AU and by primary centric model the exo-planet will take 77.7 My from now to enter the Roche’s zone. 51 Pegasi b fits accurately in the primary centric framework.

Comparative Designs-Models Fabricated for Non-conventional Energy Supply to A-four-storey Building using Gauss-Seidel Algorithm

Mon, 09 Mar 2026 00:00:00 +0000

The problems are that: (i) frequent power outage by inadequate infrastructure and outdated technologies led to poor supply, (ii) limited access to reliable electricity and high cost of installation of off-grid energy and fossil fuel caused financial burden on households in the region, (iii) lack of a reliable energy, low renewable sources and reliability misconceptions affected the usage of renewable energy in the region, (iv) overall reliance on fossil fuel such as: diesel and petrol despite its high cost had contributed to global warming, and lack of strong implementation strategies and research affected renewable energy applications in the region. The study is aimed at comparing models for non-conventional energy supply to a four storey Building using Gauss-Seidel Algorithm in Abo-Mbaise, Imo State, southeast region, Nigeria. The objectives of the study are to: (i) evaluate the current energy infrastructure and consumption pattern in a-six- person-household per flat in the region, (ii) identify the renewable energy resources available in the region, (iii) assess the technical, economic and viability of implementing different renewable energy systems in a-four-storey-Building and the environmental impact of utilization in the region, and (v) apply optimization algorithm on different renewable energy sources on design configurations and fabrication. The reliability of the research experiment was determined using Pearson product moment correlation (r). The experimental result of (r), was found to be approximately (r = 1.0) which confirmed 100% (percent) level of performance between the model and prototype (fabricated Flywheel). The result also shows that there exist a strong correlation between the designed (model) and the fabricated (prototype). The work concluded that: (i) the cost of energy per kwh from Enugu Electricity Distribution Company (EEDC) is ₦53.78, Solar/Battery option is ₦65.62, Flywheel option is ₦34.27, Biomass option is ₦49.97 and Wind option is ₦74.01.Therefore, cost of energy for a-4-hour supply per flat of 6-person-household per month from EEDC is ₦18,070, while (ii) the optimization (GA) results show that for every-24-hour: (i) Wind option has a minimum cost of N14.66million in 30years, N488,666:67K in one year, N40,722:22K in one month per Building of 8flats, and per flat of 6persons has to pay N5090:00K ($3.4 US Dollars) per month, (ii) Biomass option has a minimum cost of N20.62million in 30years, N687,333:33K in one year, N57,277:78K in one month per Building of 8flats, and per flat of 6persons has to pay N7,160:00K ($4.8 US Dollars) per month, (iii) Flywheel option has a minimum cost of N6.9million in 30years, N230,000:00K in one year, N19,166:67K in one month per Building of 8flats, and per flat of 6persons has to pay N2,396:00K ($1.6 US Dollars) per month and (iv) Solar/Battery has a minimum cost of N28.16million in 30years, N938,666:67K in one year, N78,222:22K in one month per Building of 8flats, and per flat of 6persons has to pay N9,778:00K ($6.5 US Dollars) per month. It further concluded that there is zero emission of Co₂ and other green house gasses using the Flywheel energy generating system and also it is the most efficient option. The work recommended that: for federal government of Nigeria to realize her vision/policy on climate change and SDG 2030: the Federal Housing Authority should promulgate a law for the provision of power supply in any building meant for rent age to reduce over-reliance on national grid, and the said regulatory council should implement the collection of appropriate tariffs using off-grid power supply in collaboration with other organizations in the renewable energy field.

Acellular Dermal Matrix for Post-Excisional Reconstruction in Oral Premalignant Lesions: A Clinical Study

Mandeep Singh Malhotra, Dr. Harsimran Singh, Dr. Neha Sharma — Fri, 13 Mar 2026 00:00:00 +0000

Oral premalignant lesions (OPLs) are a heterogeneous group of potentially malignant lesions, with multiple etiological factors, accounting for 17-35% of all new oral cancers. Early detection and effective management of these lesion is crucial for preventing malignant transformation. Surgical excision is the treatment modality which offers complete clinical response. The complexity of post-surgical oral mucosal defect and its restoration leads to limited as well as delayed adoptability of surgical modality. In recent years, Acellular Dermal Matrix (ADM) has emerged as an innovative solution for reconstructing oral cavity soft tissue defects. This sophisticated biomaterial scores over traditional reconstructive options like mucosal grafts and split-thickness skin grafts (STSGs) in terms of unlimited tissue availability and better recipient site outcomes. The very simple technique of ADM application and its better tissue assimilation makes it preferable over microvascular free tissue transfer which causes minimal contracture but demands specialized expertise and infrastructure limited buccal mucosa defects. In this study, we share our experience of 7 patients who underwent OPL excision with ADM restoration of oral mucosal defects between March 2023 to March 2025.

Energy at the Intrinsic Fermi Level and at the Fermi Level Pinning in the Bandgap of a Semiconductor

Ravi Kumar Chanana — Fri, 27 Mar 2026 00:00:00 +0000

This short communication describes a new way of finding energy levels in the bandgap of a semiconductor using the conductivity effective mass of electron for one valley at velocity saturation, especially in the cubic semiconductors. The already known method uses the density of states (DOS) carrier masses. The new method using the physics of the universal mass-energy equivalence relation in the differential form in semiconductors distinguishes between three types of energy levels. These energy levels are the intrinsic Fermi energy level, the pinned Fermi energy level due to high density of surface states in the bandgap, and charge neutrality level (CNL) which is the border of the donor and the acceptor states in a semiconductor bandgap. Examples of Si [100], Ge [100], GaAs [100], and amorphous thermal SiO₂ are taken to illustrate the above energy levels.

Moisture Sorption Studies of Extruded Maize/Soybean Snacks

Osibanjo A. A., Sowbhagya C. M., Olatunji O. O. — Wed, 01 Apr 2026 00:00:00 +0100

Moisture sorption studies of two variants (sweet and spiced) of extruded, ready to eat maize/soybean snacks was done to ascertain their behaviour, integrity, stability and acceptability post production, as these are dried products with a tendency for moisture uptake. The snacks were exposed to relative hunidity conditions of 11 – 92% at 27 o C, for a period of four weeks. Weighing was done weekly until equilibrium was attained. Colour and other deterioration changes were also observed. It was found that both variants were similar in composition and behaviour. Critical moisture content in the sweet variant was 9.4% (corresponding to an equilibrium RH of 44%) and 11.9% in the spiced (corresponding to an ERH of 56%) implying the maximum moisture content permissible for product acceptability. The Brunauer - Emmett - Teller (BET) monolayer moisture content was found to be 5.56 % for the sweet sample and 5.88% for the spiced, indicating the minimum moisture levels to which these samples can be dried economically and also at which the snacks have the most desirable physico-chemical attibutes and maximum stability with respect to rancidity

The Relative Variability Dependence of the Genetic Material, Interruption Epoch of Plantation and Planting on Potato Quality

Ioan Gontariu, Dan Hoffman — Wed, 01 Apr 2026 00:00:00 +0100

The agrotehnological measures which have a major negative impact on the planting material rated capacity are the following: on the first place is situated the planting of the potato 30 days later, followed by stems damaging after 20 days from the warning. From quantity point of view the later planting and the vegetation interruption had a negative effect on theplanting material rated capacity at both cultivars (Astral and Rapsodia). The diminishing of the planting material rated capacity, as a consequence of the vegetation interruption was significantly amplified when the planting activity was accomplished earlier both in Suceava and Lucina at the cultivars Rapsodia and Astral. In comparison with Suceava, in Lucina was registered a significant grows of the tuber yields used like planting material (13.3 q/ha), representing a significant increase of the yield with 9%. The quantitative estimation of the triple interactions (cultivar –planting time - stage of the vegetation interruption) suggested that the yields diminishing are caused by the later planting being dependent by the stage of the vegetation interruption too. If in Suceava those two cultivars reacted in a similar manner, in Lucina the postponement of the vegetation interruption with 20 days, attenuated the limitative effect of the planting delay only at the Astral cultivar.
