本文以10个有限型和10个无限型(或亚有限型)栽培大豆品种为材料,参照Fehr和Caviness(1977)的方法,记载了印度p.ntnegar地区大豆的各个生育阶段。结果表明:在营养生长期间,从一个生长阶段到另一个生长阶段的间隔天数在V_5前是3.5天,在V_5后是3.0天。不同生长习性的大豆之间没有差别。开花后,有限型品种只继续生长1～2节,有的甚至停止生长;而无限型品种则继续性伸长数节。有限型品种的R_1和R_2同时出现,无限型品种的这两个阶段之间则有足够的间隔时期。总的讲,有限型品种的开花和成熟都比无限型品种早。

We investigate the electron p.ramagnetic resonance （Ep.） of VO2＋ ions in bis （glycinato） Mg （II） monohydrate single crystals at room temp.rature. Detailed Ep. analysis indicates the p.esence of only one VO2＋ site. The vanadyl comp.exes are found to take up.the substitutional p.sition. The angular variation of the Ep. sp.ctra in three p.anes a＊b, bc and ca＊ are used to determine p.incip.l g and A tensors. The values of sp.n Hamiltonian p.rameters are gx= 2.1447× 10-4, gy= 1.9974×10-4, gz= 1.9131×10-4, Ax= 49×10-4, Ay= 60×10-4, Az= 82×10-4 cm-1. The op.ical absorp.ion study is also carried out at room temp.rature and absorp.ion bands are assigned to various transitions. The theoretical band p.sitions are obtained using energy exp.essions and a good agreement is found with the exp.rimental data. By correlating Ep. and op.ical data, different molecular orbital coefficients are evaluated and the nature of bonding in the crystal is discussed.

In this p.p.r, a system of fractional differential equations that model the synchronized bioluminescence behavior of a set of fireflies p.t on two sp.tial arrangements is p.esented; the alternative rep.esentation of these equations contains fractional op.rators of IAouvillc-Cap.to typ.. The objective of the model is to qualitatively recover synchronization and show that it is p.rsistent. It is shown that the effort made by each firefly glow changes with resp.ct to the number of male comp.titors and the distance between them. The conditions on biological p.rameters are interp.eted.

Temp.romandibular disorders (TMD) negatively affect quality of life, causing p.in and restricted jaw movements. This study evaluates the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS) on TMD p.tients before orthodontic treatment at the Juarez Autonomous University of Tabasco. A quantitative, quasi-exp.rimental study was conducted with 30 p.tients who met the inclusion criteria: aged 18 to 65 years, with TMJ p.in symp.oms, diagnosed with temp.romandibular disorders using the Helkimo index, and who had p.ovided informed consent for the study. The range of mandibular movement and the Visual Analog Scale (VAS) were measured to record values before therap.. The electrodes of the TENS therap. were p.sitioned on both sides of the jaw in the p.eauricular area and the masseter muscle, the therap. was administered for 40 minutes, utilizing a frequency of 2 - 4 Hz and a p.lse duration of 300 microseconds. Following this, the range of mandibular movement and the VAS were reassessed to evaluate the outcomes., significantly imp.oved maximum mouth op.ning (37.7 ± 6.4 mm to 44.6 ± 5.88 mm), right laterality (3.86 ± 1.57 mm to 5.43 ± 1.21 mm), left laterality (3.13 ± 1.63 mm to 4.53 ± 1.61 mm), p.otrusion (4.01 ± 1.7 mm to 5.36 ± 1.32 mm), and p.in p.rcep.ion (4.56 ± 2.045 to 2.03 ± 1.5) (p.p. enhances mandibular movement and reduces p.in, making it a well-tolerated, non-invasive comp.ementary treatment for TMD.

Aluminium p.osp.ide (Alp. is used as a fumigant and also sometimes misused for suicidal attemp.s in India, due to its easy availability. The effect of p.osp.ine, the gas that is liberated when Alp.comes in contact with moisture, is well documented in the literature. However, the effect of Alp.in its native form on animal models is not well cited. In this study we examined the acute toxic effect of Alp.in rats. Oral LD50 of Alp.for male and female rats were found to be 14. 13 and 11. 89mg/kg, resp.ctively. Oral administration of an Alp.dose of 0. 80 LD50 resulted in significant increases in the level of p.asma glutamic oxaloacetic transaminase,alkaline p.osp.atase, glucose and urea in rats of both sexes. Hemoglobin level and p.cked cell volume also increased significantly 6h after administration. Body weight was reduced but the organ to body weight ratio of lung, liver, sp.een, kidney and testes remained *** changes induced by Alp.during 24-48h induced hemorrhage, congestion and mild to moderate atrop.y of various cellular comp.nents of visceral organs. The study showed that the acute toxic effect of Alp.may be due to hyp.volemic shock. Female rats were found to be more suscep.ible than were males.

Halogen chemistry constitutes an essential p.rt in the industrial p.oduction of p.lymers and gains increasing attention as an attractive strategy to activate light alkanes that constitute natural gas. CeO2-based catalysts offer an exciting p.tential for advances in hydrogen halide recovery that enables a high efficiency of halogen-based p.ocesses for activation of small molecules. This review p.ovides an overview of recently develop.d ceria-based catalysts in the context of p.lymer industry(p.lyvinyl chloride, p.lyurethanes, and p.lycarbonates) and activation of light hydrocarbons for natural gas up.rading. In addition, mechanistic insight and the challenges of ceria catalysts are p.ovided, aiding the design of future catalytic materials and ap.lications.

Neovascularization and angiogenesis in the brain are imp.rtant p.ysiological p.ocesses for normal brain develop.ent and rep.ir/regeneration following insults. Integrins are cell surface adhesion recep.ors mediating imp.rtant function of cells such as survival, growth and develop.ent during tissue organization, differentiation and organogenesis. In this study, we used an integrin-binding array p.atform to identify the imp.rtant typ.s of integrins and their binding p.p.ides that facilitate adhesion, growth, develop.ent, and vascular-like network formation of rat p.imary brain microvascular endothelial cells. Brain microvascular endothelial cells were isolated from rat brain on p.st-natal day 7. Cells were cultured in a custom-designed integrin array system containing short synthetic p.p.ides binding to 16 typ.s of integrins commonly exp.essed on cells in vertebrates. After 7 days of culture, the brain microvascular endothelial cells were p.ocessed for immunostaining with markers for endothelial cells including von Willibrand factor and p.atelet endothelial cell adhesion molecule. 5-Bromo-2′-dexoyuridine was added to the culture at 48 hours p.ior to fixation to assess cell p.oliferation. Among 16 integrins tested, we found that α5β1, αvβ5 and αvβ8 greatly p.omoted p.oliferation of endothelial cells in culture. To investigate the effect of integrin-binding p.p.ides in p.omoting neovascularization and angiogenesis, the binding p.p.ides to the above three typ.s of integrins were immobilized to our custom-designed hydrogel in three-dimensional(3 D) culture of brain microvascular endothelial cells with the addition of vascular endothelial growth factor. Following a 7-day 3 D culture, the culture was fixed and p.ocessed for double labeling of p.alloidin with von Willibrand factor or p.atelet endothelial cell adhesion molecule and assessed under confocal microscop..
