A boundary layer analysis is presented for the natural convection past a horizontal plate in a porous medium saturated with a nano fluid. Numerical results for friction factor, surface heat transfer rate and mass transfer rate have been presented for parametric variations of the buoyancy ratio parameter Nr, Brownian motion parameter Nb, thermophoresis parameter Nt and Lewis number Le. The dependency of the friction factor, surface heat transfer rate (Nusselt number) and mass transfer rate on these parameters has been discussed.

In this paper, an improved analytical model for IEEE 802.11 distributed coordination function (DCF) under finite load is proposed by closely following the specifications given in IEEE 802.11 standard. The model is investigated in terms of channel throughput under perfect and slow Rayleigh fading channels. It is shown that the proposed model gives better insight into the operation of DCF.

Lanthanum oxide impregnated large-pore zeolite catalysts were prepared. The catalysts were characterized by XRD （X-ray diffraction）, PSA （particle size analysis）, TPD （temperature programmed desorption） and SEM （scanning electron microscope）. The performances of the catalysts were investigated using the alkylation reaction of naphthalene with methanol. Under comparable conditions, the La-impregnated β-zeolite catalyst showed the highest catalytic activity among all the catalysts tested. The lower reaction temperature is favorable for the formation of 2,6-dimethyl naphthalene.

Inferior vena cava pseudo aneurysms are rare clinical entities with an uncertain natural history due to its rarity and limited follow up information. IVC injuries are managed according to the patient’s presentation and hemodynamic status. This case report describes clinical presentation of a 30 years old man with history of fall from height, infra renal IVC pseudoaneurysm found with FAST and CT scan abdomen, our treatment plan and his clinical outcome.

Lymphomas are known as neoplasm’s caused by clone proliferation of B and T lymphocytes. Extranodal lymphoma arises from tissues other than lymph nodes or even from sites which normally doesn’t contain lymph tissues. Orbital adnexal lymphoma arises from eyelid, orbit, lacrimal glands or conjunctivae and it is totally different from intraocular lymphoma. Wide range of differential diagnosis including infectious inflammatory orbital disease, preseptal and orbital cellulitis, orbital idiopathic inflammatory disease-pseudotumors, especially dacryoadenitis and myositis and thyroid associate orbit disease makes the diagnosis of orbital adnexal lymphoma even more difficult. We represent the case of diagnostic delay of very aggressive form orbital non-Hodgkin lymphoma occurred because of the unspecific signs and symptoms as well as not indicative imaging investigation and laboratory tests.
