Slaughterhouse workers(SHW) are at increased risk of hepatitis which can occur due to different organisms and should be investigated for viral, bacterial, and parasitic organisms. Slaughter house personnel including butchers are at a higher risk of infections from cuts and blood-letting, with the possible risk of the transmission of blood-borne pathogens to their colleagues. The objective of this review is to evaluate the common etiologies of hepatitis in SHW which will assist in the assessment of these patients presenting with transaminitis. Types of Microorganisms causing hepatitis with their reservoirs, routes of transmission,laboratory diagnosis, clinical features, treatment options and preventive strategies are included in this review. Proper investigation and awareness is of utmost importance as it causes significant financial constraints derived from workers health cost and from livestock production losses when the disease is confirmed. The work up is essential because infected workers might be a source of infections to other colleagues, family and the consumers.

Hiatal hernia(HH) contents commonly include stomach, transverse colon, small intestine, and spleen but herniation of the pancreas is an extremely rare phenomenon.79-year-old female with multiple comorbidities presented to emergency department with complaints of weight loss for 6 mo and abdominal pain for one day. Physical examination revealed cachectic and dehydrated female and bowel sounds could be auscultated on the right side of chest. Computed tomography of the chest and abdomen revealed interval enlargement of a massive HH,containing stomach and much of the bowel as well as pancreas and distal extrahepatic biliary duct, probably responsible for obstructive effect upon same. There was increased prominence of the pancreas consistent with pancreatitis. There was a large HH causing obstructive effect with dilated biliary system along gall bladder wall edema and pancreatitis. Patient clinical status improved with conservative *** presenting with acute pancreatitis is a serious diagnostic and therapeutic challenge. The initial management is conservative, even if the abdominal content has herniated to mediastinum. The incentive spirometry can be utilized in the conservative of the large HH. After stabilization of the patient, elective surgical intervention remains the mainstay of the management. Definitive treatment will vary from case to case depending on the acuity of situation and comorbidities.

Numerical solution is presented for the two- dimensional flow of a micropolar fluid between two porous coaxial disks of different permeability for a range of Reynolds number Re （-300≤ Re 〈 0） and permeability parameter A （1.0≤A ≤2.0）. The main flow is superimposed by the injection at the surfaces of the two disks. Von Karman＇s similarity transformations are used to reduce the governing equations of motion to a set of non-linear coupled ordinary differential equations （ODEs） in dimensionless form. An algorithm based on the finite difference method is employed to solve these ODEs and Richardson＇s extrapolation is used to obtain higher order accuracy. The results indicate that the parameters Re and A have a strong influence on the velocity and microrotation profiles, shear stresses at the disks and the position of the viscous/shear layer. The micropolar material constants cl, c2, c3 have profound effect on microrotation as compared to their effect on streamwise and axial velocity profiles. The results of micropolar fluids are compared with the results for Newtonian fluids.

We investigate the effects of jet production on the following parameters： pseudorapidity, transverse momentum and transverse mass distributions of secondary charged particles produced in pp-collisions at 1.8 Te V,using the HIJING code. These distributions are analyzed for the whole range and for six selected regions of the polar angle as a function of the different number of jets. The obtained simulation results for these parameters are interpreted and discussed in connection to the increase observed in the multiplicity of secondary charged particles as a result of its multi-jet dependence, and are also discussed in comparison with the experimental results from the CDF Collaboration.
