Abstract: 

ZEOLITE MEMBRANE SCIENCE IS A WELL-KNOWN POWERFUL TOOL IN DELICATE SEPARATION PURPOSES BECAUSE OF THEIR REGULAR STRUCTURE THAT IS KNOWN AS MOLECULAR SIEVE. MEMBRANE GAS SEPARATION (GS) IS A PRESSURE-DRIVEN PROCESS WITH DIFFERENT INDUSTRIAL APPLICATIONS THAT REPRESENT ONLY A SMALL FRACTION OF THE POTENTIAL APPLICATIONS IN THE GAS REFINERY PLANTS AND CHEMICAL INDUSTRIES. IN THE RECENT YEARS, MANY EFFORTS HAVE BEEN PERFORMED FOR DEVELOPMENT OF VARIETY AND QUALITY OF ZEOLITE MEMBRANES FOR SEPARATION AND CATALYTIC APPLICATION. IN THE SEPARATION OF SMALL GASEOUS MOLECULES, ZEOLITE MEMBRANES WITH THE SMALL PORE SIZE ARE USED. ANALCIME (ANA) ZEOLITE CRYSTALS SHOWS A TYPICAL NANOPOROUS THREE DIMENSIONAL STRUCTURE WITH IRREGULAR CHANNELS (0.42 0.16 NM) OF HIGHLY DISTORTED 8- RINGS. IN THIS WORK, WE HAVE INVESTIGATED ON MOLECULAR SIEVE PROPERTIES OF NANOPOROUS ANA ZEOLITE MEMBRANES. THE ANA ZEOLITE MEMBRANE IS SYNTHESIZED ON NEUTRAL CERAMIC POROUS SUPPORT USING HYDROTHERMAL SECONDARY GROWTH METHOD. THE MEMBRANES IS USED FOR SEPARATION OF VARIOUS GASES WITH PARTICULAR ATTENTION TO THE SELECTIVE SEPARATION OF HYDROGEN GAS. EVALUATION OF MEMBRANE PERMEANCE AND IDEAL SEPARATION FACTOR IS DONE BY SEPARATION OF VARIOUS GASES SUCH AS H2, CH4, CO2 AND N2 USING ACCURATE EXPERIMENTAL APPARATUS. CRYSTALLINE PHASE OF ZEOLITIC LAYERS HAVE BEEN CHARACTERIZED BY XRD ANALYSIS.

Abstract: 

The story of "shah Rukh and Golruk" lyrical stories of the twelfth century AD, including Khyalangyzy stories in which the hero with supernatural forces of world domination is natural. This story is unparagraphed prose between the Safavie eras. As the abundance of words, the use of compounds in Arabic, the verb attribute Azvjh, compositing, Atnabhay successive ensure the use Of the deeds and words of special meaning and use of words in Turkish and Mongolian features is its lightness.Story writer intellectual approach based on three lyrical, epic and education. As the writer to advance their story forms and epic scenes, festive and combat applies in Ghana. Then, using the results of a religious approach to education focuses on the ethical issues. This article results of research remained the only version * of the story, "Shah Rukh She 'that it analyzed the stylistic features.

INTRODUCTION: THE LARGE NUMBER AND VARIETY OF AUTOANTIBODIES CAN BE SEEN AGAINST NUCLEAR AND CYTOPLASM ANTIGENS IN RHEUMATIC DISEASES. THE SELECTIVE AND SENSITIVE METHOD FOR DETECTION OF THESE AUTOANTIBODIES IS IMMUNOFLUORESCENT TECHNIQUE. IN THIS TECHNIQUE LOWER TITRATION OF 1/100 CONSIDERED TO BE NEGATIVE AND HIGHER TITERS ARE POSITIVE. ...

Abstract: 

NOWADAYS, AUTOIMMUNE DISEASES, ARE CONSIDERED AS A MAIN PROBLEM IN MEDICAL COMMUNITIES AND DIAGNOSIS, MANAGEMENTAND TREATMENT OF THESE DISORDERS, ARE VERY IMPORTANT. ANTI NUCLEAR ANTIBODY (ANA) IS ONE OF THE COMMON ASSAYS FORSCREENING OF RHEUMATIC DISEASES WHICH IS DETERMINANT IN DIAGNOSIS OF THESE DISEASES TREATMENT. MATERIALS AND METHOD: THIS STUDY, WAS FORMED DUE TO THE MISCONCEPTION ABOUT ANA TEST, THAT FREQUENTLY IS PERFORMED WITH METHODS BASED UPONSOLID PHASE AS ELISA. THIS EXPERIMENT WAS CONDUCTED ON 215 PATIENTS, WITH CLINICAL SYMPTOMS, THAT ARE LIKELY AFFECTEDWITH RHEUMATIC DISEASES, SIMULTANEOUSLY, BY MEANS OF ANA AND FANA. ...

Abstract: 

Objective: Systemic lupus erythematosus (SLE), an autoimmune systemic disease with unknown etiology, affects virtually every part of the body; involvement of the central nervous system (CNS) is one of the major causes of morbidity and mortality in systemic lupus erythematosus (SLE) patients and is the least understood aspect of the disease. Neutropenia is very uncommon in childhood lupus. True negative anti nuclear antibody (ANA) tests in patients with lupus are now very rare. The patient reported here was a 12-year-old girl with ANA negative lupus cerebritis who presented with left hemiparesia after a generalized seizure, with neutropenia observed during its course.

Abstract: 

A Novel modified Analcime (Na16 (Al16Si32O96) · 16H2O) zeolite with a new molar ratio have been successfully synthesized. In order to investigate the role of the template, Different samples were synthesized with and without Tetramethylammoniumhydroxide (TMAOH) template through hydrothermal method. Different synthesis times (24, 36 and 72 hours) and molar ratios have been utilized. The optimum sample with highest Crystallinity (95. 2%) has been used as seed for synthesis of analcime membrane on α-alumina support via Seed-assisted crystallization method. The resultant analcime membranes were then modified by Cu+2 and Ni+2 by ion exchange method. Synthesis of these materials is confirmed by the XRD, EDX and SEM methods. The SEM results of modified membranes showed that the surface of the support is shielded with a continuous layer of Ni+2 and Cu+2 crystals and the analcime zeolite are not destructed. Also, the results of XRD patterns verified that the main diffraction peaks of synthesized zeolites are similar to the analcime zeolite component and ion exchange reactions have not disturbed the structure of zeolite. Furthermore, the purity of analcime zeolites and its orthorhombic structure has been established. It should be mentioned that the modified membrane can be merged as a potential material for many applications such as gas separation.

Abstract: 

INTRODUCTION: FOR THE SEROLOGICAL DIAGNOSIS OF SYSTEMIC AUTOIMMUNE RHEUMATIC DISEASES, A TWO-TIER APPROACH STARTING WITH SENSITIVE ANTINUCLEAR ANTIBODY (ANA) DETECTION BY INDIRECT IMMUNOFLUORESCENCE (IIF) ON HEP-2 CELLS FOLLOWED BY CHARACTERIZATION OF POSITIVE FINDINGS WITH DIFFERENT IMMUNOASSAYS IS RECOMMENDED. TO OVERCOME DRAWBACKS OF THIS APPROACH, WE DEVELOPED A NOVEL TECHNIQUE ALLOWING THE COMBINATION OF SCREENING AND SIMULTANEOUS CONFIRMATORY TESTING. THUS, FOR THE FIRST TIME, THIS CREATES THE BASIS FOR NEXT-GENERATION ANA TESTING...
