This study deals with the theoretical analysis of thermal explosion criticality slice-chain and temperature distribution for a unidirectional flow of hydromagnetic exothermic Oldroyd 8-constant\nreactive fluid. With negligible material consumption and absence of currents displacement, the reactive flow takes place in a bounded plane Couette device. The flow momentum is not caused by the chemical reaction but by the upper motion of the wall in the presence of initiation\nrate, Bimolecular generalized kinetics and reaction chain-branch order. The solutions to the nonlinear combustible, non-Newtonian fluid is done using a semi-analytical Weighted residual method coupled with collocation integrating scheme. Graphical results for the flow velocity field, temperature distribution and the bifurcation slice diagram for the thermal ignition criticality are presented. It is seen that the solution depends on the magnetic and material terms,\nbut activation energy has no significant effect on the considered reactive fluid.

The study aimed to evaluate the internal morphology of Passiflora eichleriana Mast., Passiflora nitida Kunth. and Passiflora mucronata Lam. seeds cryopreserved with different cryoprotectants. The treatment were control (without cryoprotectant or cryopreservation), seeds cryopreserved without cryoprotectant, 1.73, 2.28, 2.60 or 2.71 M glycerol, 0.37, 0.46, 0.54 or 0.61 M sucrose and 0.37, 0.72, 1.04 or 1.35 M dimethylsulfoxide. The seeds were cryopreserved in liquid nitrogen (-196 °C) for seven days. The cryopreserved seeds were dipped in water bath (37 °C) for 5 minutes to defrost. The percentage of filled, empty, malformed and damaged seeds was determined. The seeds were analyzed by x-ray to verify damages caused by the cryopreservation or defrost. Our results demonstrate that x-ray is an efficient method to analyses cryopreserved seeds and the cryopreservation technique did not affect the quality of P. eichleriana, P. nitida and P. mucronata seeds.

Cenomanian marine carbonates in the northern flank of dj. Bou Arif are composed of two members showing different features : member Touil, with dominance of marl facies and member Dellal, composed of marl-limestone complex, wherein the beds of limestone vary in thickness from a few centimeters to several decimeters. These members are superimposed to constitute the Fahdene formation.\nThe micropaleontological study in the Cenomanian of Bou Arif proved the existence of 36 species of foraminifera (17 planktonic and 19 benthic) and 11 ostracods. Benthic foraminifera and ostracods have been used mainly as paleoecological tools and/ or as witnesses to environmental conditions. The biostratigraphic study is based, essentially, on the detailed analysis of planktonic foraminifera and the ammonites collected in the field. Applying the concepts of biostratigraphy allowed to distinguish different planktonic biozones, ranging from The Vraconien Thalmanninella appenninica IZ, the lower Cenomanian to the basal part of the middle Cenomanian Thalmanninella brotzeni IZ, the middle Cenomanian Thalmanninella reicheli IZ and the upper parte of middle Cenomanian to the lower parte of upper Cenomanian Rotalipora cushmani TRZ.\nCenomanian strata of Bou Arif section are composed of medium- to thick-bedded, mostly grainy limestones with various skeletal (bivalves, foraminifera and echinoderms) and nonskeletal (ooliths, peloids) components. Facies analysis documents low- to high-energy environments, including lagoonal, barrier, and open-marine facies.\nThe vertical distribution pattern in the measured section suggests a third-order depositional sequence constitutes of two transgressive-regressive sequences (BS1 & BS2). Each sequence is caracterized by Transgressive system tracts (TST) within typically show retrogradation deposits from lagoonal to deep open marine facies; the latter usually include the maximum flooding (MFZ). During Highstand systems tracts (HST), there is a progradation of facies from deep- and shallow marine facies were gradationally overlain by shallow marine barrier and lagoonal facies in shallowing-upward trends.

A numerical simulation of a patient’s nasal airflow using computational fluid dynamic (CFD) was developed. The CT scans of a patient with both septal deviation and allergy rhinitis are obtained, and the three-dimensional (3D) nasal model is being constructed by using InVeselius 3.0, then imported to CATIA V5 for modification and finally imported into ANSYS FLUENT for the numerical solution. The velocity contours of the cross-sectional area for the four main surfaces, which include the vestibule, nasal valve, middle turbinate, and nasopharynx, are being analyzed. The mass flow rate, pressure, and velocity magnitude are assessed with the standardized nasal cavity.
