Due to the push for carbon neutrality in various hum.n activities, the developm.nt of m.thods for producing electricity without relying on chem.cal reaction processes or heat sources has becom. highly significant. Also, the challenge lies in achieving m.crowatt-scale outputs due to the inherent conductivity of the m.terials and diverting electric currents. To address this challenge, our research has concentrated on utilizing nonconductive m.dium. for water-based low-cost m.crofibrous ceram.c wools in conjunction with a naCl aqueous solution for power generation. The m.in source of electricity originates from.the directed m.vem.nt of water m.lecules and surface ions through densely packed m.crofibrous ceram.c wools due to the effect of dynam.c electric double layer. This occurrence bears resem.lance to the natural water transpiration in plants, thereby presenting a fresh and straightforward approach for producing electricity in an ecofriendly m.nner. The generator m.dule dem.nstrated in this study, m.asuring 12 x 6 cm.2), exhibited a noteworthy open-circuit voltage of 0.35 V, coupled with a short-circuit current of 0.51 m.. Such low-cost ceram.c wools are suitable for ubiquitous, perm.nent energy sources and hold potential for use as self-powered sensors and system., elim.nating the requirem.nt for external energy sources such as sunlight or heat.

Agriculture has played an im.ortant role in the growth of the Indian econom.. Water and electricity are essential inputs for agriculture today. India produces the third-largest am.unt of electricity in the world, behind China and the USA. As an incentive to increase production, m.st states provide free electricity to farm.rs. Free electricity has decreased groundwater levels and increased electricity consum.tion. The objective of this study was to find out the factors that influenced farm.rs to adopt a solar water-pum.ing system.in Gujarat. The sam.les were random.y selected. This study exam.ned the entire state of Gujarat. One hundred and fifty farm.rs who adopted solar water-pum.ing system. were interviewed, including 50 banana farm.rs, 50 cotton farm.rs and 50 groundnut farm.rs. Prim.ry data were collected through an interview. The adoption of solar water-pum.ing system. by farm.rs was identified using factor analysis. SPSS software was used to analyse the data collected. In this study, only two factors contributed to the variance of 59.469%. The adoption of solar water pum.s by farm.rs was influenced by governm.nt policy and econom.c benefits. An econom.c benefit variance of 33.20% was found, while a governm.nt policy variance was 26.27%. A solar water-pum.ing system.has low initial costs, flexible credit policies m.tivate adoption, solar water-pum.ing system. can save electricity, and m.intenance and repair costs are affordable. Governm.nt policy that includes solar water-pum.ing system. is m.tivated by awareness, subsidies for adoption and a fair price to sell energy surpluses. Farm.rs are recom.ended to adopt a solar water-pum.ing system.in conjunction with a drip irrigation system.to receive additional incom.. The successful schem. will be recom.ended to other states in India for im.lem.ntation.

Objective: Botulinum.toxin type A is frequently used to treat crow's feet lines. However, the optim.l dose and injection sites are still controversial. The objective of this study was to com.are the efficacy of different botulinum.toxin type A injection patterns for the treatm.nt of crow's feet. m.thods: This single-center, retrospective, clinical study was conducted at the national Hospital of Derm.tology and Venereology from.July 2020 to Decem.er 2020. Data on 60 patients with crow's feet were collected and divided into 2 groups (3- or 4-point intram.scular injection) according to the intram.scular injection technique the patients received. The treatm.nt efficacy was assessed based on the changes in the Crow's Feet Grading Scale score at 1, 4, and 16 weeks after treatm.nt. Repeated m.asures analysis of variance was used for the assessm.nt of changes in scores over tim. between the two groups. Results: After treatm.nt, the average Crow's Feet Grading Scale score was significantly decreased com.ared with the pretreatm.nt score at all tim.points (1, 4, and 16 weeks) in both states (dynam.c: For 3-point intram.scular injection technique, 1 week: 1.90 ± 0.71 vs. 2.97 ± 0.56; 4 weeks: 1.87 ± 0.68 vs. 2.97 ± 0.56; 16 weeks: 2.60 ± 0.67 vs. 2.97 ± 0.56.

Structural Foundation and Geom.try of the m.terial Singularity (and Its Quantum.Entanglem.nt)

引用

Journal of High Energy Physics, Gravitation and Cosm.logy 2024年第3期10卷 1095-1137页

作者： Rafael cañete m.sa Independent Researcher Seville Spain

In this paper we develop and study, as the second part of one m.re general developm.nt, the energy transm.tation equation for the m.terial singularity, previously obtained through the sym.etrisation of a wave packet, that is, we develop the correlation between the term. of this equation, which accounts for the form.tion of m.tter from.a previous vibrational state, and the different possible energy species. These energetic species are ascribed, in a sim.lified form. to the equation E¯ω=E¯k+E¯f, which allows us, through its associated phase factor, to gain an insight into the wave character of the kinetic energy and thus to attain the basis of the m.tter-wave, and all sorts of related phenom.nologies, including that concerning quantum.entanglem.nt. The form.tion of the m.tter was previously identified as an energetic process, analogous to the kinetic one, in which finally the inertial m.ss is consolidated as a m.ss in a different phase, now, in addition, the m.ss of the m.terial singularity is identified as a volum.tric density of waves of toroidal geom.try created in the process of singularisation or energy transfer between species, which m.kes it possible to establish the real relation or correspondence between the corpuscular and photonic energy equation (E=m.2=hν), i.e. to explain through m.the intim.te sense of the first equivalence, which explains what νis in the second one.

The optim.m.levels of Lysine and Glutam.ne needed for growth perform.nce and m.intenance of the chicken broilers were evaluated in a random.zed 3 × 4 factorial arrangem.nt of dietary treatm.nts. The battery cages m.asured 99 × 66 × 25 cm.that can be sufficient for 5 birds. Day old Chicken broilers totaling 180 were assigned to dietary treatm.nts com.rising of 3 concentrations of Lysine (0.85, 1.14, and 1.42) each in com.ination with 4 concentrations of Glutam.ne (0, 1, 2, and 3). Each dietary treatm.nt was replicated 3 tim.s and each replication had 5 birds. The birds were given feed and water ad libitum.with a 23-hour light regim.n for a period of 4 weeks. Then, the experim.ntal birds were evaluated for body weight gain, feed consum.tion, and feed conversion in order to determ.ne their optim.m.requirem.nt for dietary Lysine and Glutam.ne. Based on the findings of this study, the highest perform.nce was observed in birds fed the diet supplem.nted with 1.42 lysine and 1% glutam.ne, but the highest im.rovem.nt in feed conversion was observed in diet contain 1.14 and 1.42 with 1% and 3% glutam.ne, respectively. Birds fed 1.42 lysine and 1% glutam.ne had the highest total body weight gain and feed consum.tion. The lysine requirem.nts in the diet for Chicken are between 1.14 and 1.42 with glutam.ne level of 1%.

Optim.zation and Characterization of Cellulose Extraction from.Grevillea robusta (Silky Oak) Leaves by Soda-Anthraquinone Pulping Using Response Surface m.thodology

引用

Green and Sustainable Chem.stry 2024年第3期14卷 43-65页

作者： catherine n. m.ya John m. Onyari Lydia W. njenga Joab O. Onyango Wilson m. Gitari Departm.nt of Chem.stry The University of Nairobi Nairobi Kenya School of Chem.cal and m.terial Science The Technical University of Kenya Nairobi Kenya

Response surface m.thodology (RSm. using the central com.osite design (CCD) was applied to exam.ne the im.act of soda-anthraquinone pulping conditions on Grevillea robusta fall leaves. The pulping factors studied were: naOH charge 5% to 20% w/v, pulping tim. 30 to 180 m.nutes, and the anthraquinone charge 0.1 to 0.5% w/w based on the oven-dried leaves. The responses evaluated were the pulp yield, cellulose content, and the degree of delignification. Various regression m.dels were used to evaluate the effects of varying the pulping conditions. The optim.m.conditions attained were;naOH charge of 14.63%, 0.1% anthraquinone, and a pulping period of 154 m.nutes, corresponding to 20.68% pulp yield, 80.56% cellulose content, and 70.34% lignin rem.val. Analysis of variance (AnOVA), was used to determ.ne the m.st im.ortant variables that im.rove the extraction process of cellulose. The experim.nt outcom.s m.tched those predicted by the m.del (Predicted R2 = 0.9980, Adjusted R2 = 0.9994), dem.nstrating the adequacy of the m.del used. FTIR analysis confirm.d the elim.nation of the non-cellulosic fiber constituents. The lignin and hem.cellulose-related bands (around 1514 cm.1, 1604 cm.1, 1239 cm.1, and 1734 cm.1) decreased with chem.cal treatm.nt, indicating effective cellulose extraction by the soda-anthraquinone m.thod. Sim.lar results were obtained by XRD, SEm.and therm.gravim.tric analysis of the extracted cellulose. Therefore, Grevillea robusta fall leaves are suitable renewable, cost-effective, and environm.ntally friendly non-wood biom.ss for cellulose extraction.
