1. A new method for ob.aining small deep grafts is presented.2. The method allows the area from which the grafts are takento heal b. primary u.ion and with minimal scar formation.3. Many grafts may b. taken withou. the produ.tion of a disfigu.-ing scar.4. Owing to primary closu.e, less chance is offered for secondaryinfection.5. On accou.t of the simple and easy technic, this method iswell adaptab.e for u.e in any hospital or clinic.

Temperatu.e stru.tu.e parameter in the vertical is estimated once b. u.ing the tu.b.lence ou.er scale approximation and another b. u.ing the Ob.khov similarity relationship du.ing the formation of an elevated inversion.A comparison of the profiles drawn u.ing b.th the methods is done for the pu.- pose of assessing the accu.acy of the similarity method when applied to levels ab.ve the su.face-b.sed *** profiles ob.ained b. b.th the methods are also compared with a similar profile ob.ained af- ter considering a b.lk shear b.tween the grou.d and top of the elevated layer.

We attempted to stu.y the role of HLA HLA-A, b. DRb. and DQb. in HIV-1 patient’s co infected with pu.monary tu.0}rcu.osis (PTb.. A total of 102 HIV-1 + patients co-infected with pu.monary tu.0}rcu.osis and 200 healthy controls were inclu.ed in HLA analysis. HLA-A*, HLA-b. HLA-DRb.* and DQb.* typing was done molecu.arly b. PCR- SSOP (Polymerase Chain reaction-Sequ.nce Specific Oligonu.leotide Prob.ng) method u.ing kit (Dynal Kit – Invitrogen). The frequ.ncies of the HLA-A, b.HLA-DRb.1 and DQb. alleles were determined u.ing standard software. The HLA alleles identified among HIV + ve/PTb.+ ve co-infected patients as compared with healthy controls showed a significantly increased frequ.ncy of HLA-b.08:01:01 in HIV + ve/PTb.+ ve co-infected patients when compared with healthy controls (p = 0.011, OR 3.335, 95% CI 1.35-8.18), Likewise HLA-DQb.*03:01:03 was significantly increased in HIV + ve/PTb.+ ve co-infected patients as against healthy controls (p b.06:01:02 allele frequ.ncy was ob.erved in HIV + ve/PTb.+ ve co-infected patients as against healthy controls (p = 0.003, OR 4.808, 95% CI 1.72-13.39), HLA-DQb.*03:01:01 (p = 0.045, OR 0.219, 95% CI 0.051 - 0.940), HLA-DQb.*06:01:01:01 (p = 0.012, OR 0.334, 95% CI 0.145 - 0.770), alleles in HIV + ve/PTb.+ ve co-infected patients when compared with healthy controls. We can b. conclu.ed that different HLA alleles may render su.ceptib.lity or protection to in different ethnic popu.ation.

In this paper, some stab.lity resu.ts were reviewed. A su.tab.e and complete Lyapu.ov fu.ction for the hard spring model was constru.ted u.ing the Cartwright method. This approach was compared with the existing resu.ts which confirmed a su.erior glob.l stab.lity resu.t. Ou. contrib.tion relies on its application to high damping door constru.tions.

This stu.y was designed to screen and characterize antib.otic produ.ing b.cteria and fu.gi from soil samples from a waste du.p site in Enu.u. The molecu.ar characterization of the isolates was performed b. u.ing Zymo Research Qu.ck-DNA fu.gi/b.cteria miniprep kit. The b.cteria isolates were Providencia stu.rtii, Providencia alcalifaciens. b.cillu. sp., Streptococcu. sp., Micrococcu. sp., and Staphylococcu. sp while Aspergillu. fu.igatu. and Aspergillu. niger were fu.gal isolates. The efficacy of the Cru.e Extract (CE) of the antib.otics produ.ed was tested against species of Staphylococcu. au.eu. and Escherichia coli. The CE of antib.otics when compared with a conventional antib.otic (Ciprofloxacin) showed lower antimicrob.al activity. The minimu. inhib.tory concentration of the cru.e extracts ranged b.tween 12.5% and 25% concentrations while the minimu. b.ctericidal concentration ranged from 25% and 50% concentrations. The findings su.gest that these organisms have the potential to produ.e antib.otics and cou.d b. harnessed b. pharmaceu.ical indu.tries for the produ.tion of newer antib.otics.

Su.face defects cau.ed du.ing cu.ting and polishing in the fab.ication of cadmiu. zinc tellu.ide (CdZnTe) nu.lear detectors limit their spectral performance. Chemical treatments are often u.ed to remove su.face damages and defects. In this paper, we present the analysis of Te and TeO2 species on the su.faces of CdZnTe nu.lear detectors treated with hydrogen b.omide and ammoniu.-b.sed solu.ions. The CdZnTe wafers were chemo-mechanically polished in a mixtu.e of hydrogen b.omide in hydrogen peroxide and ethylene glycol, followed b. a chemical passivation in a mixtu.e of ammoniu. flu.ride and hydrogen peroxide solu.ion. X-ray photoelectron spectroscopy showed significant conversion of Te to TeO2, thu. produ.ing a more chemically stab.e su.face. The resistivity of the CdZnTe samples is in the order of 1010 ohms-cm. The cu.rent for a given applied voltage increased following the passivation and decreased after a 3-hou. period. Resu.ts from spectral response measu.ements showed that the 59.5-keV gamma-peak of Am-241 was stab.e u.der the same channel for the su.face treatment processes.

Individu.l differe nces in cog nition have b.en shown to b. common in some animal taxa, and recent evidenee su.gests that an individu.l's personality can b. associated with an individu.ds cognitive strategy. We tested whether wild b.t-eared foxes Otocyon megalotis differ in a risktaking b.havior (tameness) and whether this trait correlated with appetitive association learning performanee. While ou. resu.t shows that individu.ls differed in their tameness, we fou.d no associati on b.tween this personality trait and learning the appetitive association. This resu.t does not su.port the framework that differe nces in cog nition are associated with differe nces in personality;however, ou. small sample size does not allow u. to assert that pers on ality can not b. associated with cog nition in this system. This stu.y highlights that measu.i ng cog nition and pers on ality in wild systems presents added difficu.ty and that correlations fou.d in captive animals may not b. evident in their wild cou.terparts.
