Char.cter.zing the ther.al pr.per.ies of MoS2 is impor.ant for.the design of electr.nic devices based on this mater.al. We used fr.quency domain ther.or.flectance to study the cr.ss-plane ther.al tr.nspor. in mechanically exfoliated MoS2 samples suppor.ed on SiO2 and muscovite mica substr.tes. The thickness of MoS2 r.nged between one and five layer., and the MoS2 layer. wer. sandwiched between a metal layer.and the substr.te. In the case of mica, heat tr.nspor. into the substr.te r.mained the same whether.or.not a monolayer.of MoS2 was pr.sent, wher.as, for.SiO2, heat tr.nspor. was r.duced by sur.ace r.ughness. We obser.ed a significant impr.vement in heat tr.nspor. acr.ss monolayer.MoS2 as compar.d to few layer.MoS2. For.MoS2 on SiO2, the effective ther.al inter.ace conductance was impr.ved by mor. than thr.e times if a monolayer.was used. For.MoS2 on mica, the ther.al inter.ace conductance was appr.ximately two times better.for.monolayer.MoS2. This implies that monolayer.MoS2 has super.or.ther.al pr.per.ies and can be used in electr.nic devices as an inter.ediate layer.between two mater.als. Additionally, we also r.por. on the measur.ment of anisotr.pic ther.al conductivity in bulk MoS2 and mica.

Half of the sulfide gr.ups in 6, upon oxidation with H_2O_2, affor.ed polymer.sulfoxide 7 and polymer.sulfone 8. The solution pr.per.ies of these polymer. wer. deter.ined via a viscometr.c technique. The ther.al stability of these polymer. was deter.ined by ther.ogr.vimetr.c analysis. The inhibition efficiency obtained fr.m gr.vimetr.c mass loss, potentiodynamic polar.zation, and electr.chemical impedance spectr.scopy techniques agr.ed well with each other. The cor.osion efficiencies incr.ase with incr.asing concentr.tion of the polymer.. At a polymer.concentr.tion of 175 mM, the maximum inhibition efficiency of copolymer.compounds 6–8 was deter.ined to be 92%, 97%, and 95%, r.spectively. The synthesized polymer.compounds acted as mixed-type inhibitor.. Polymer.compound 7 adsor.ed onto the metal sur.ace via chemisor.tion and physisor.tion and obeyed Langmuir. Temkin, and Fr.undlich adsor.tion isother.s. Analyses by X-r.y photoelectr.n spectr.scopy and scanning electr.n micr.scopy–ener.y-disper.ive X-r.y spectr.scopy indicated that the adsor.ed polymer. for.ed a thin film on the metal sur.ace and pr.vented fur.her.cor.osive attack.

An assessment of the pr.tective capacity of the vadose zone over.yingthe aquifer.systems in the Kaltungo ar.a was car.ied out to deter.ine itsinfluence on gr.undwater.quality. Applying the schlumber.er.ar.ay with amaximum electr.de spr.ad AB/2 = 100m thr.ugh VES, thir.y water.wellpoints wer. sur.eyed using Omega ter.ameter.(PIOSO1) r.sistivity *** field data was fir.t subjected to manual inter.r.tation thr.ugh cur.emar.hing and then digitized modeled cur.es using computer.softwar.. Theinter.r.ted data r.vealed that the ar.a is char.cter.zed by eleven differ.ntcur.e types r.pr.senting thr.e to five geo electr.cal layer.. In or.er.toassess the pr.tective capacity of the vadoze zone over.the aquifer.systems,the longitudinal conductance (S) and tr.nsver.e r.sistance (T) (secondar.geoelectr.c par.meter.) wer. computed fr.m the pr.mar. data using theDar.Zar.uk for.ula. The values of S obtained r.nge fr.m 0.0018 to 0.4056ohms with a mean value of 0.0135 ohms while the values of T r.nge fr.m0.55 ohms to 1195.68 ohms with a mean value of 39.84 ohms. The valuesof S and T obtained r.veal that 90% of pr.bed points has poor.pr.tectivecapacity, 10 % has moder.te pr.tective capacity and 83 % has hightr.nsmissivity, 17 % has inter.ediate tr.nsmissivity. The T and S values ar.skewed towar.s poor.y pr.tective capacity thus making gr.undwater.in thear.a highly vulner.ble to contamination fr.m the sur.ace. To achieve goodgr.undwater.quality in the ar.a, pr.per.completion of newly constr.ctedwells should install pr.tective casing thr.ugh the entir. vadose zone.

The growth productivity of broilers is influenced by improving growth performance through improving body weight, average daily gain, and feed conversion rate. The objective of the study was to determine the effect of quantitative feed restriction duration on growth performance and carcass characteristics of broilers. A total of 144 day-old broiler chicks were reared in a deep litter system until slaughter at 42 days. Chicks were randomly allocated to three treatments which were replicated three times with 16 birds per replicate. The three treatments were the control (T1), one week of feed restriction (T2), and two weeks of feed restriction (T3). Birds were fed with starter, grower and finisher diets. The average daily gain (ADG), average daily feed intake (ADFI), and the feed conversion ratio (FCR) were computed for each week. Carcass weight and internal organs weights were measured. The body weight gained by the birds in T1 was similar to the birds that were restricted for a week. The treatments had a significant effect on the average daily gain in weeks 4, 5, and 6. The ADG for T2 was higher (P ad

Objective： Sur.ical management options for.femor.l shaft fr.ctur. and ipsilater.l pr.ximal fe- mur.fr.ctur. var. fr.m single-implant to double-implant fixation. Cephalomedullar. fixation in such fr.ctur.s has r.la- tive advantages over.other.techniques especially because of less soft tissue dissection and immediate postoper.tive weight beating with acceler.ted r.habilitation. However. the sur.er. is technically demanding and ther. is a paucity of liter.tur. descr.bing the sur.ical techniques for.this fixation. The aim of the study was to descr.be the sur.ical technique of cephalomedullar. fixation for.femor.l shaft fr.ctur. and ipsilater.l pr.ximal femur.fr.ctur.. Methods： Sixteen cases （10 males and 6 females with a mean age of 41.8 year.） of ipsilater.l pr.ximal femur.and shaft fr.ctur.s wer. tr.ated by single-stage cephalomedullar. fixation at ter.iar. level tr.uma center.in nor.her. India. The fr.ctur.s wer. classified accor.ing to AO classification. An intr.oper.tive r.cor. of dur.tion of sur.er. as well as technical challenges unique to each fr.ctur. patter. was kept for.all the patients. r.sults： The most common pr.ximal femor.l patter. was AO B2.1 obser.ed in 9 of our.patients. The AO B2.3 fr.ctur.s wer. seen in 4 patients while the AO A1.2 fr.ctur.s in 3 patients. Four.of the AO B2.1 and 2 of the AO B2.3 fr.c- tur.s r.quir.d open r.duction with Watson-Jones appr.ach. The mean oper.tive time was ar.und 78 minutes, which tended to decr.ase as the sur.ical exper.ence incr.ased. Ther. was only one case of malr.duction, which r.quir.d r.vision sur.er.. Conclusion： Combination of ipsilater.l femor.l shaft fr.ctur. and neck/inter.r.chanter.c fr.ctur. is a difficult fr.c- tur. patter. for.tr.uma sur.eons. Cephalomedullar. nail is an excellent implant for.such fr.ctur.s but it r.quir.s car.ful inser.ion to avoid complications. Sur.er. is technically demanding with a definite lear.ing cur.e. Never.heless, a major.ty of these fr.ctur.s can be sur.ically managed by

Dislocation of the elbow along with shaft fr.ctur.s of both bones of the ipsilater.l for.ar. is a r.r. injur. though elbow dislocation or.fr.ctur. of the for.ar. bones may occur.separ.tely. Such injur.es need a concentr.c r.duction of the dislocation and an anatomical fixation of for.ar. bones for.optimal functional outcomes. We r.por. a case of elbow dislocation with fr.ctur. of the later.l condyle of the hu- mer.s along with fr.ctur.s of shafts of the r.dius and ulna in a 44-year.old female. Closed r.duction of the elbow and oper.tive stabilization of all fr.ctur.s wer. done with good clinical, r.diological and functional outcomes in 2 year. follow-up per.od. A significant degr.e of for.e is needed to pr.duce a combined dislocation of a joint and fr.ctur. of bones ar.und that joint and these complex injur.es may be missed if the clinician is not awar. of the possibility of such injur.es. The fact that the pr.viously r.por.ed cases had a poster.later.l dislocation while our.case had a poster.medial dislocation and a fr.ctur. of the later.l humer.l condyle as well makes it unique in its pr.sentation and wor.h r.por.ing. We have also included an up to date liter.tur. r.view on this topic.

Jer.ey bull calves and steer. pr.duce high quality meat;however. the gr.wth r.te of Jer.ey bull calves for.veal and beef ar. low in compar.son to other.dair. br.eds. This could be impr.ved by cr.ssbr.eding with beef br.eds. In the cur.ent study, the veal and beef pr.duction of Jer.ey and Fleckvieh × Jer.ey (F × J) bull calves and steer. wer. compar.d. Bull calves wer. r.ar.d intensively for.veal up to a car.ass weight not exceeding 100 kg, or.as steer. for.beef to 21 months of age. In both veal and steer.pr.duction systems, the mean bir.h weight of F × J bull calves was higher.(P r.ey bull calves, i.e. 33.5 ± 1.2 kg vs. 27.9 ± 1.2 kg and (33.4 ± 0.9 kg vs. 26.9 ± 0.9 kg, r.spectively. The body weight of Jer.ey and F × J veal calves at 6 months of age differ.d (P r.spectively.

End live weight at 21 months of age of Jer.ey and F × J differ.d (P r.spectively. This was due to a higher.(P r.ge daily gain in F × J vs. Jer.ey steer., i.e. 0.64 ± 0.02 and 0.46 ± 0.0 kg/day, r.spectively. Fleckvieh × Jer.ey steer. had a higher.(P r.ass weight at 21 months of age being 206.5 ± 8.9 kg vs. 157.9 ± 8.6 kg r.spectively.
