rating medicinal plants based on the total number of drug shows that the mint plant species, withgeneral name mentha, among the most consumption herbs that are used in various industries such aspharmaceutical, food, cosmetics and health. drying process, in order to maintain the quality andquantity of essential oil extraction have a great role in the processing medicinal plants. importantaspects...
in this assay, the evaluation of lipophilicity of four ace-inhibitors and hydrochlorothiazide (hctz) with rp-tlc on cellulose layers was described using three binary solvent systems. the selected ace inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with hctz. in addition, the linea...
روش کروماتوگرافی لایه نازک که با پردازش عکس کوپل شده است جهت تجزیه کمی همزمانی آمینواسیدها مورد بررسی قرار گرفته شده است. به این منظور لوسین و ایزو لوسین که ایزومرهم می باشند انتخاب شد و اندازه گیری آنها انجام شد. علاوه بر تجزیه کمی، از روش چند متغیر پردازش عکس، جهت تجزیه کیفی استفاده می شود که در این راستا طبقه بندی جوهر های خودکارهای آبی صورت گرفت. سیستم تشخیصی وسیله عکس برداری می باشد. عکس ه...
many research studies have been performed on forced convection (active) solar dryers for fruit and vegetables. a short survey of these showed that applying the forced convection solar dryer not only significantly reduced the drying time but also resulted in many improvements in the quality of the dried products. active indirect and mixed-mode thin layer solar drying experiments were conducted o...
After several decades of mining, the block has entered development stage ultra-high water cut. Although encryption adjustment and subdivision for different mining objects have been completed, interlayer interference is still serious invalid cycle exists, making it difficult to develop adjust. The injection well can further improve production degree various oil layers, effectively utilization ra...
Mattan tailam, a siddha herbo-mineral oil was prepared and chemically analysed. The physico chemical parameters and thin layer chromatographic pattern were evolved to lay down the standards, The data presented can be used for fixing standards to mattan tailam.
The problems of steady film condensation on a vertical surface embedded in a thin porous medium with anisotropic permeability filled with pure saturated vapour are studied analytically by using the Brinkman-Darcy flow model. The principal axes of anisotropic permeability are oriented in a direction that non-coincident with the gravity force. On the basis of the flow permeability tensor due to t...
Elastic wave-based oil mobilization of residual in heterogeneous reservoirs is a viable, low-cost, and green technology method enhanced recovery (EOR). Applications for elastic (seismic) waves at the reservoir scale are currently preliminary stages investigation development. We employ two-layer numerical finite element (FEM) this research to investigate possibility effective propagation seismic...
Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...
