The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presence of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is carried out. Three types of nanoparticles, each having a different shape, are considered. These shapes include spherical(Fe_3O_4), cylindrical(Au), and platelet(Zn) configurations. The combination approach is utilized to evaluate the physical and thermal characteristics of the trihybrid and hybrid nanofluids, excluding the thermal conductivity and dynamic viscosity. These two properties are inferred by means of the interpolation method based on the volume fraction of nanoparticles. The governing equation is transformed into a dimensionless form, and the Adomian decomposition Sumudu transform method(ADSTM) is adopted to solve the conundrum of a moving fin immersed in a trihybrid nanofluid. The obtained results agree well with those numerical simulation results, indicating that this research is reliable. The influence of diverse factors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphical representations. Furthermore, the fluctuations in the heat transfer concerning the pertinent parameters are studied. The results show that the heat flux in the presence of the combination of spherical, cylindrical, and platelet nanoparticles is higher than that in the presence of the combination of only spherical and cylindrical nanoparticles. The temperature at the fin tip increases by 0.705 759% when the value of the Peclet number increases by 400%, while decreases by 11.825 13% when the value of the Hartman number increases by 400%.

Factor V Leiden is the most common genetic thrombophilia in people of Europea n descent, and is important to recognize as it can have significant implications in dermatology. We report a case of a 30- year-old man who presented for eva luation and treatment of a chronic ulceration on the site of his stump following a below the knee amputation which had been performed for non-healing ulcerati ons. Despite a variety of treatments, his ulcer persisted. He was referred to a dermatologist who performed a biopsy that was interpreted ass non-specific, an d treatment was started for pyoderma gangrenosum. Further investigation revealed a homozygous factor V Leiden mutation and cryofibrinogenemia. He was tapered of f of the methylprednisolone and was improving on stanozolol. He healed well afte r surgery and no new ulcerations have developed. This case highlights the import ance of considering this mutation in a non-healing leg ulcer.

The thermoluminescence(TL)emission of synthetic and natural ce-monazites was characterized here to determine the potential application in the identification of microscopic defects from a qualitative point of view trying to link each TL peak to a chemical-physical *** kinetic parameters that lead the luminescence processes were calculated by means of variable heating rate and computing glow curve deconvolution methods and allow identifying three groups of components at~90,130 and 290℃(for the mineral sample)and~90,170,220,270 and 320℃(for the synthetic cePO_(4):Nd_(0.20),La_(0.25)).The main differences appreciated in these complex TL curves are mainly due to(i)the content of impurities(natural sample contains lanthanides as well as U 0.60%and Th 5.22%)and(ii)the degree of crystallinity of the samples which is directly related to the type of impurities(synthetic monazite relies only on Nd and La).The behavior of the dose response in the range of 1-8 Gy is similar for both samples;the TL intensity increases linearly as the dose increases without changes in the position of the maxima,denoting first-order kinetic luminescence *** peak could be mostly associated with structural defects(i.e.,phase transitions),chemical reactions(i.e.,ce3+?ce4+redox reaction,dehydration or dehydroxylation processes)or intrinsic defects(i.e.,Frenkel defects,ODcs or NBOHcs).

In this work,several ceria-zirconia based catalysts with very lo w(and equimolar) metal contents were prepared,characterised and tested for the cO oxidatio n reaction(under lean and stoichiometric conditions),trying to emulate those conditions found in a diesel oxidation catalyst(DOc) system from a diesel engine and those encountered under gasoline exhaust(λ=1).The metals chosen are cu,co,Ag and Pt(as a reliable benchmark).The results reveal enormous differences among reducibility and catalytic activity despite quite similar structural and textural properties of the catalysts,showing differences among dispersion(Ag-catalyst seems to present a low level of dispersion).This catalyst seems to be characterised,as well,by a strong electronic interaction between ce and Ag centres which is suggested to yield an improved reducibility under H_(2)-TPR ***,the order in catalytic activity(cu>Ag>co≈Pt>>support) seems not to follow the order found in reducibility and the cu-catalyst seems to be the most active independently on the reaction conditions,yielding nearly overlapped cO oxidation catalytic *** restingly,a stro ng correlation between the catalytic activity under the two conditions tested and the OSc values of the ce_(0.8)Zr_(0.2)O_(2)-supported metal catalysts is ***,OSc parameter measured at 150℃ can be used as a relevant descriptor to evaluate the cO oxidation activity at low and medium conversions for the investigated catalysts,much better than the H_(2)-TPR measurements.

外科病理诊断中肿瘤发生皮肤转移并不少见，其提示肿瘤复发或发生结外扩散。某些恶性肿瘤如肾细胞癌发生皮肤转移的临床症状可能会导致皮肤原发性恶性肿瘤的诊断。有3％～11％肾细胞癌可发生皮肤转移，而皮肤转移性肾细胞癌的形态学特点与皮肤原发的附属器肿瘤特别是具有透明细胞分化者难以鉴别。为了确定cD10在各种皮肤附属器病变中的表达以及其在区分转移性肾细胞癌中的价值，作者研究了57例原发性附属器肿瘤，其中小汗腺分化31例，大汗腺分化16例，皮脂腺分化10例、正常皮肤3例和4例皮肤转移性肾细胞癌。结果发现cD10表达于正常皮肤的皮脂腺，小汗腺和大汗腺上皮表达阴性，而汗腺周围的肌上皮细胞表达cD10。
