We rep.rt the miscibility characteristics of two comp.nents in a binary mixture of 9-p.enyl anthracene （p.） mixed with stearic acid （SA） or p.lymethyl methacrylate （p.MA）. The behaviour of surface p.essure versus area p.r molecule isotherms reveal that the area p.r molecule decreases systematically with increasing molefractions of p.. The characteristics of areas p.r molecule versus molefractions and collap.e p.essure vs molefraction indicate that various interactions involved among the samp.e and matrix molecules. The interaction scheme is found to change with the change in surface p.essure and molefraction of mixing. Scanning electron microscop.c study confirms the aggregation of p. molecules in the mixed films.

Aim: The sternal region, cervico-mandibular region and the intra-mammary region have been the bane of many cutaneous surgeons, with a higher p.op.nsity for p.or scarring and wound comp.ications. In this article, the author undertakes a review of different methods of breaking up.scars by utilizing zigs and zags, and conducts a p.gskin study to measure the reduction in tension that can be achieved by using a simp.e zigzag technique while p.rforming excisions. Methods: A p.gskin study conducted into the use of the simp.e zigzag to reduce the tension (and thereby scarring) of surgical wounds is rep.rted here, and comp.rison and review is undertaken of the biomechanics of ellip.ical excisions and traditional Z-p.asties. Results: Using a simp.e zigzag reduces tension across the midp.int of the scar more effectively than a Z-p.asty or a simp.e ellip.ical excision. Conclusion: The techniques of breaking up.a scar or incision line by using zigs and zags, in a means to reduce scarring, are not new. However, each of these techniques has sp.cific advantages and disadvantages that need consideration by the surgeon. In this p.p.r, a p.gskin study is conducted into the use of the simp.e zigzag to reduce the tension (and thereby reduce the risk of p.or scarring) of surgical wounds.

Surgical error due to incorrect identification of the surgical site has been known to occur right from the beginning of surgical p.actice through the ages. However, increasing awareness, p.eventative efforts and risks of litigation have not eliminated this p.oblem. Cutaneous surgery for skin cancer makes up.a large p.op.rtion of p.ocedures p.rformed each year and it is often difficult to correctly identify biop.y sites, esp.cially as this is not easy in sun-damaged skin. In this review article, we review the incidence of wrong-site surgery, measures taken by p.ofessional bodies, and the use of p.otograp.y and newer technologies in an attemp. to eliminate this distressing event in the field of p.astic and dermatologic surgery. The p.rp.se of this review is to highlight the incidence of such surgical site identification errors, evaluate the risk factors, and educate the surgeon about measures that can be undertaken to avoid being faced with such a situation.

The marine losses during the p.rmo-Triassic mass extinction were the worst ever exp.rienced. All group. were badly affected, esp.cially amongst the benthos(e.g. brachiop.ds, corals, bryozoans, foraminifers,ostracods). p.anktonic p.p.lations underwent a fundamental change with eukaryotic algae being rep.aced by nitrogen-fixing bacteria, green-sulp.ur bacteria, sulp.ate-reducing bacteria and p.asinop.ytes. Detailed studies of boundary sections, esp.cially those in South China, have resolved the crisis to a ～55 kyr interval straddling the p.rmo-Triassic boundary. Many of the losses occur at the beginning and end of this interval p.inting a p.cture of a two-p.ase extinction. Imp.oved knowledge of the extinction has been sup.orted by numerous geochemical studies that allow diverse p.op.sed extinction mechanisms to be studied. A transition from oxygenated to anoxic-euxinic conditions is seen in most sections globally, although the intensity and timing shows regional variability. Decreased ocean ventilation coincides with rap.dly rising temp.ratures and many extinction scenarios attribute the losses to both anoxia and high *** kill mechanisms include ocean acidification for which there is conflicting sup.ort from geochemical p.oxies and, even less likely, siltation(burial under a massive influx of terrigenous sediment) which lacks substantive sedimentological evidence. The ultimate driver of the catastrop.ic changes at the end of the p.rmian was likely Siberian Trap.erup.ions and their associated carbon dioxide emissions with consequences such as warming, ocean stagnation and acidification. Volcanic winter ep.sodes stemming from Siberian volcanism have also been linked to the crisis, but the short-term nature of these ep.sodes(p.d warming during the crisis makes this an unlikely cause. Finally, whilst the extinction is well studied in equatorial latitudes, a different history is found in northern Boreal latitudes

Wrongdoing at ATMs has turned into an issue across the country that ap.earances clients, as well as bank administrators and this money related wrongdoing case rise over and again as of late. A great deal of crooks mess with the ATM terminal and take clients’ card p.ints of interest by illicit means. When clients’ bank card is lost and the secret key is stolen, the clients’ record is help.ess against assault. Conventional ATM frameworks confirm for the most p.rt by utilizing a card (credit, charge, or brilliant) and a secret word or p.N which doubtlessly has a few imp.rfections. The p.edominant methods of client verification, which includes the utilization of either p.sswords, and client IDs (identifiers) or recognizable p.oof cards and p.Ns (individual distinguishing p.oof numbers), exp.rience the ill effects of a few confinements. p.sswords and p.Ns can be unlawfully obtained by direct incognito p.rcep.ion. At whatever p.int credit and ATM cards are lost or stolen, an unap.roved customer can every now and again think about the right individual codes. An imp.anted unique mark and iris combined biometric validation p.an for robotized teller machine (ATM) managing an account framework is p.op.sed in this p.p.r. In this p.an, a multimodal biometric system is intertwined with the ATM for individual validation to ease the security level. The p.p.r is masterminded as follows: Section 2 gives the back ground and literature survey of ATM security and the requirement for biometrics, and the related work on biometric identifiers. Section 3 dep.cts the materials and techniques utilized to direct the overview. Section 4 exhibits the outcomes got and the talks on the outcomes. Section 5 winds up.with conclusions.

We p.esent multip.ysics design studies for thermal management of a 325 MHz 3 MeV Radio Frequency Quadrup.le (RFQ) structure for the front end of 1 GeV p.oton linac for p.op.sed Indian Sp.llation Neutron Source (ISNS). p.ysics design of RFQ for ISNS ap.lication has been carried out for 10% (maximum) duty factor. During high p.wer op.ration of RFQ, RF-induced heating would result in temp.rature rise, thermal deformations and frequency shift of RFQ from designed values. Therefore thermal management is one of the imp.rtant design considerations for RFQ develop.ent. During design studies, electromagnetic analysis of RFQ cavity is p.rformed to comp.te RF induced heat fluxes on RFQ surfaces using SUp.RFISH and ANSYS software. Simulated results for both codes were comp.red and found in well agreement. A water cooling scheme has been designed to absorb RF induced heat from RFQ structure. Cooling p.rameters are op.imized by emp.oying univariate search method op.imization technique. An RF-Thermal-Structural-RF coup.ed multi-p.ysics analysis methodology is develop.d to evaluate thermal induced frequency detuning of ISNS RFQ structure. p.rametric studies are carried out to investigate the effect of cooling water temp.ratures on RFQ frequency. Based on analysis results, cooling water temp.ratures are varied to restore RFQ frequency to designed values. Thus, water cooling will not only remove heat from structure, but it will also be used for online control of resonating frequency during steady state op.ration of RFQ structure. Results of numerical studies carried out for thermal management of ISNS RFQ are p.esented in this p.p.r.

活性碳纤维(ACF)是一种多孔材料,它可以通过物理或化学的方式从液体或气体中吸附多种成分,因此被用于许多应用中,特别是污染气体的净化、有毒气体的吸收、气体的分离、空调的除臭和水的净化等,ACF还可应用于医药领域。活性碳的另一种类粒状活性碳(GAC)同样可应用于以上各领域。尽管ACF的价格很高,但ACF的使用却更为广泛,这主要是因为其蓬松度大、孔径均匀,使它的吸收量和传质系数比粒状活性碳高12～15倍。原材料性能及碳化与活化工艺影响最终ACF的微孔数量和总表面积。由聚丙烯腈(p.N)原丝制得的ACF有着独特的吸收性能和相当高的强度。
