BACKGROUND h.moph.lia, an uncommon yet consequential h.reditary bleeding disorder, manifests as two clinically indistinguish.ble forms th.t h.nder th. normal functioning of th. coagulation cascade. Th.s impairment renders individuals more susceptible to excessive bleeding during significant surgical interventions. Moreover, individuals with.severe h.moph.lia frequently encounter recurring h.marth.osis, resulting in progressive joint destruction and, subsequently, th. need for h.p and knee replacement *** SUMMARY Th. patient was a 53-year-old man with.h.moph.lia A as th. underlying disease and h.d self-injected factor Ⅷ twice weekly for several decades. h. h.d undergone ankle fusion surgery for recurrent h.marth.osis at th. Department of Orth.pedic Surgery 1 mo prior and was referred to our department because of skin necrosis after a h.matoma at th. surgical site. An anterolateral th.gh.perforator free flap was created after th.ee cycles of factor Ⅷ administration in addition to th. concomitant administration of tranexamic acid(TXA)(Transamin 250 mg cap, 1 cap tid, q8h.. After th. operation, from postoperative days(PODs) 1-5, th. factor Ⅷ dose and interval were maintained, and q12h.administration was tapered to q24h.administration after POD 6. Because th. patient’s flap was stable 12 d after th. operation, factor Ⅷ administration was tapered to twice a week. At 6 mo follow-up, th. patient recovered well with.ut any *** To th. best of our knowledge, th.re are very few reports of successful free flaps in patients with.h.moph.lia, and none h.ve been reported in patients with.h.moph.lia A. Moreover, th.re are several reports on th. efficacy of TXA in free flaps in general patients;h.wever, th.re are no case reports of combining factor Ⅷ and TXA in patients with.h.moph.lia. Th.refore, we report th.s case to contribute to future academic research.

Artificial ph.tosynth.sis uses a catalyst to convert CO2 into valuable h.drocarbon products by cleaving th. C--O bond. h.wever, th.s tech.ology is strongly limited by two issues, namely insufficient catalytic efficiency and complicated catalyst-fabrication processes. h.rein, we report th. development of a novel spray-drying ph.tocatalyst-engineering process th.t addresses th.se two issues. Th.ough.one-step spray drying, with.a residence time of 1.5 s, nanocomposites composed of tin oxide （SnO2） nanoparticles and edge-oxidized graph.ne oxide （eo-GO） sh.ets were fabricated with.ut post-treatment. Th.se nanocomposites exh.bited 28-fold and five-fold enh.ncements in ph.tocatalytic efficiency during CO2 reduction compared to SnO2 and commercialized TiO2 （P25）, respectively, after irradiation with.simulated sunligh. for 4 h. Th.s scalable approach. based on sh.rt residence times and facile equipment setup, promotes th. practical application of artificial ph.tosynth.sis th.ough.th. potential mass production of efficient ph.tocatalysts.

For our KDP crystal orientation, various tbermo-optic （TO） and relevant temperature-dependence param- eters are defined, presented, and studied in th. framework of a transverse and a longitudinal electro-optic （eo） modulation systems. Th.s study is based on th. concept of th. so-called opto-electrical bias （~） ap- plied to th. system. For both.of th. above eo-modulation systems, a set of original equations is extracted and investigated with.regard to each.of th. more important TO or temperature coefficients. Using th.se equations, for th.se parameters th. role of th. transverse configuration is examined in comparison with.its corresponding longitudinal configuration. A comparison is done with.oth.r orientation of th. same KDP crystal.

It is well known th.t increasing th. rotational velocity is an effective way to increase th. total pressure ratio. With.increasing flow velocity especially under th. condition of transonic flow in th. supersonic region, wh.re exist strong sh.ck waves, th. sh.ck wave loss becomes main and important. Simultaneously, th.re occurs boundary layer separation due to th. sh.ck wave / boundary layer interaction. In th. present paper th. transonic compressor blades were studied and analyzed to find a proper and simple way to reduce th. sh.ck wave loss by optimizing th. suction surface configuration or controlling th. gradient of isentropic Mach.number on th. suction surface. A Navier-Stokes solver combined with.a modified design algorith. was developed and used. Th. NASA single rotor for transonic flow compressor was served as a numerical example to sh.w th. effectiveness of th.s meth.d. Two cases for both.original and modified rotors were analyzed and compared.

Polygynous males can ch.nge th.ir mating tactics across th.ir lifetime, but information is scarce on th. flexibility of th.s trait with.n a given season and th. relative costs and benefits of using different tactics. h.re, we monitored individually marked male reindeer Rangifer tarandus and classified th.ir mating tactics as h.rem-defense, sneaking, or mixed. Th. costs of th. male reproductive effort were assessed using both.direct （i.e. percentage of body mass lost） and indirect measures （i.e. activity patterns such.as feeding, standing, and walking）, wh.le mating group size and reproductive success were recorded as mating ef- fort benefits. Our results sh.w th.t reindeer males may switch.between th. h.rem-defense and sneaking tactics th.ough.ut th. same breeding season, providing furth.r support to th. notion th.t reproductive tactics are flexible in ungulates. Th. costs and benefits of male mating effort vary according to th. mating tactic, reach.ng th. h.gh.st values in h.rem-h.lders and th. lowest values in sneaking males. Moreover, males wh. switch.d between th. sneaking tactic and th. h.rem-defence tactic tended to ach.eve h.gh.r mating success th.n males wh. consistently used th. least costly tactic. Indeed, all h.rem-h.lders successfully sired offspring, wh.reas only two out of th.ee mixed-tactic males sired one calf, and sneaking males did not sire any calves. In conclusion, our results sh.w th.t reindeer males can modulate th.ir mating efforts during th. same breeding season by switch.ng between th. most costly h.rem-defense tactic and th. least costly sneaking tactic, suggesting individual solutions to th. balance between reproductive effort and mating opportunities [Current Zoology 61 （5）： 802-810, 2015].

Ch.racteristics of th. temporal evolution of th. global solar magnetic field were found to display a 2-step cycling mode consistent with.a pattern of a fundamental h.rmonic progression underlying all solar cycles at all times and h.ving its seat in th. fusion region of th. core via nuclear magnetic resonance as part of th. h.drogen and h.lium fusion ch.in. In addition to th. th.ee principal zones in th. interior of th. sun, core, radiative zone, and convection zone, a sub-surface layer is being suggested to take part in th. processes of varying solar activity, wh.ch.would be an extension of relativistic 2D h.drogen being formed th.ough.ut th. plasma body under th. influence of pressure waves originating in th. core. Th. major participants confined to such.a 2D layer is for th. most part 2D h.drogen particularly in its form of relativistic 2D h.drogen, wh.re th. Boh.atom binding energies are replaced by binding energies in th. range of eo = 0.5 MeV. For th.s reason it is conjectured th.t th.s condition lends itself to providing contributions to (a) th. energy release including 0.5 MeV and lower energy γ-ph.tons as well as (b) superimposing a radial component to th. global dipole field.
