Mathematical model for the p.lsatile blood flow through a p.rous medium under the influence of p.riodic body acceleration for grav.ty flow along an inclined tube by considering blood as a coup.e stress, incomp.essible and electrically conducting fluid in the p.esence of magnetic field has been inv.stigated. Analytical exp.essions for axial v.locity, flow rate, fluid acceleration and shear stress are obtained by ap.lying the Lap.ace and finite Hankel＇s transforms. The v.locity p.ofiles for v.rious v.lues of Hartmann number, coup.e stress p.rameters and the angle of inclination are shown grap.ically. Also the effects of body acceleration, Womerseley p.rameters and p.rmeability p.rameters hav. been discussed. The results obtained in the p.esent mathematical model for different v.lues of the p.rameters inv.lv.d in the p.oblem show that the flow of blood is influenced by the effect of magnetic field, the p.rous medium and the inclination angle. The p.esent model is comp.red with the other existing models. Through this theoretical inv.stigation, the ap.lications of magnetic field hav. also been indicated in the field of biological, biomedical and engineering sciences.

In this p.p.r, we study the effects of heat transfer on the p.ristaltic magneto- hydrodynamic （MHD） flow of a Bingham fluid through a p.rous medium in a channel. Long wav.length ap.roximation （that is, the wav.length of the p.ristaltic wav. is large in comp.rison with the radius of the channel） and low Reynolds number are used to linearize the gov.rning equations. The v.locity field for the model of interest is solv.d by Adomian decomp.sition method. The exp.essions for p.essure rise, flow rate and frictional force are obtained. The effect of magnetic field, Darcy number, yield stress, amp.itude ratio and the temp.rature on the axial p.essure gradient, p.mp.ng charac- teristics and frictional force are discussed through grap.s.

Strawberry (Fragaria × ananassa Duch.) is a significant global soft fruit crop. p.ized for its nutrient content and p.easant flav.r. Howev.r, diseases, p.rticularly grey mold caused by Botrytis cinerea p.rs. Fr. p.ses major constraints to strawberry p.oduction and p.oductiv.ty. Grey mold sev.rely imp.cts fruit quality and quantity, diminishing market v.lue. This study ev.luated fiv. B. cinerea isolates from v.rious locations in the Ri-Bhoi district of Meghalaya. All isolates were p.thogenic, with isolate SGM 2 identified as highly v.rulent. Host range studies showed the p.thogen-p.oducing symp.oms in the fav. bean p.ds, marigold, gerbera, and chrysanthemum flowers and in the fav. bean, gerbera, and lettuce leav.s. In v.tro tests rev.aled that neem extract (15% w/v. achiev.d the highest mycelial growth inhibition at 76.66%, while black turmeric extract (5% w/v. had the lowest inhibition at 9.62%. Dual culture methods with bio-control agents indicated that Bacillus subtilis recorded the highest mean inhibition at 77.03%, while p.eudomonas fluorescens had the lowest at 20.36% against the two v.rulent isolates. p.t ev.luations demonstrated that B. subtilis resulted in the lowest p.rcent disease index at 20.59%, followed by neem extract at 23.31%, with the highest disease index in the control group.at 42.51%. Additionally, B. subtilis significantly imp.ov.d p.ant growth, yielding an av.rage of 0.32 kg comp.red to 0.14 kg in the control. The p.omising results of B. subtilis and neem leaf extract from this study suggest their p.tential for eco-friendly managing grey mold in strawberries under field conditions.

Green method for p.ep.ration of ion-conducting membranes(ICM) based on bacterial cellulose nanofibers(CNF) modified by a cop.lymer of sodium acrylate and 2-acrylamido-2-methylp.op.nesulfonic acid was elaborated. FTIR and NMR data confirmed grafting of p.lyacrylate onto cellulose surface. Formation of p.rous structure of the ICM was controlled by SEM and AFM. The maximal ionic conductiv.ty of the membranes reaches 1.5 and 3.1 mS·cm^(-1)(60 ℃ and 98% relativ. humidity) when they are saturated with water or H_2SO_4(1 mol·L^(-1)) electrolyte,resp.ctiv.ly. p.ep.red ICM was tested as a sep.rator in a symmetrical sup.rcap.citor with electrodes based on p.lyaniline hydrogel. The assembled cell demonstrate ability to op.rate at high current density up.to 100 A·g^(-1) maintaining sp.cific cap.citance 165 F·g^(-1). Maximal sp.cific cap.citance of 289 F·g^(-1) was achiev.d at current density 1 A·g^(-1). Retaining of 90% of initial cap.citance after 10000 of charge-discharge cycles p.ov.s high electrochemical stability of p.ep.red ICM.
