Isolated non Compaction of left ventricular myocardium is a rare cardiomyopathy due to abnormal endomyocardialmorphogenesis.The incidence of non Compaction cardiomyopathy in the general population has been estimated at 0.05% to 0.25% per year.NCCMP is a heart muscle disorder that is still little known among physicians and was first described in 1984 by engberding and bender.Echocardiography is diagnostic method of choice.We report our recent experience with six NCCM patients who present at our hospital between September2011and April 2012. Three patients were with severe symptoms, two patients with mild symptoms and one patient was asymptomatic. serial follow up and medical management is advisable in these patients for improving outcome.

Correlations between plasticity index (LL, PL ,PI), Compaction effort and Compaction characteristics (ωopt,γdmax) are of most importance in soil mechanics. Clays with different plastic properties are collected from different regions in Azarbaijan and Gorgan. These soils have been compacted with different Compaction methods (Standard Proctor, Modified Proctor and Reduced Compaction). Then changes in the Compaction characteristics due to variation of plastic properties and Compaction effort have been investigated. Man made clayey soils are produced from the natural collected soils. These soils had constant fine grain percent ages. The effect of fine grains on Compaction characteristics has been studied in these samples. In this research it has been concluded that increasing of Compaction effort has different effects on improving of maximum dry density. Soils with high PI are more affected with Compaction effort than low PI clays. Compaction curves shape showed that in clays with high PI the concaveness of the Compaction curve is low and their sensitivity to water content variation are less than those of high PI clays.

Flexible Pavement has the most share for road construction in most countries. Iran also follows this rule. In most asphalt pavements design methods, there is less focus on base and subbase layers and most of the researches are focused on the asphalt layer. Since the behavior of these materials is different in the short and long term due to the elastoplastic properties, it’ s so important to examine their behavior before using in the pavement layers and also behavioral comparison between different types of materials. This leads to the choice of the best type of pavement materials and the best conditions for grading, moisture and Compaction. In results, it is important to select the Test conditions that can accurately simulate the actual stresses on the pavement. Light weight deflectometer (LWD) Test is usually used to determine the bearing strength of the unbound layers of the pavement. The purpose of this study is to examine simultaneously the role of the effective factors associated with the base layer on the behavior of this layer using of LWD Test. The selected effective factors include Compaction, thickness, and moisture content of the layer. The results show that increasing of Compaction from 87% to 97%, and layer thickness from 20 to 40cm, the surface modulus of layer is significantly increased and deflection is reduced. Also, the results show that the changes in the moisture content of the layer did not have effect on the modulus and deflection of the layer.

Soil strength and elasticity modules are important parameters in the engineering characteristics of soils. Bearing capacity is increased by soil strength. Elasticity module determines the potential of soil deformation. In this experiment, stabilization of problematic clay soils using sands were investigated. The samples were prepared with variable soil moisture and Compaction, and were Tested in single-axis compression apparatus in the soil mechanics laboratory of Shahid Chamran University (SCU) in Khuzistan province. The samples were Tested with soil moistures as follows: optimum humidity, 2% and 4% less than optimum, and 2% and 4% more than optimum moisture. The Compaction of applied, R.C, were equal to 85, 95 and 100 percents. Using the obtained data, the soil strength and elasticity modules were calculated. Our findings show that for all in clay and sandy-clay samples Tested increasing moisture lead to decrease of soil strength. However, reduction of soil strength in the sandyclay sample is more than problematic clay soils samples. Results of these experiments regarding the moisture change from 4% less than optimum to 4% more than optimum, decreased soil strength of problematic clay soil, approximate 84%, while, for sandy-clay soil it was about 93 percents. Moreover, decreasing of elasticity module in sandy clay samples with 100% Compaction and 13% moisture is approximately 51 percents.

Isolated ventricular non-Compaction is a rare congenital cardiomyopathy, manifested morphologically as prominent myocardial trabeculations and deep recesses that communicate with the ventricular cavity. Heart failure is the most common presenting condition. This report is illustrative of isolated ventricular non-Compaction in a 51-year-old male. The diagnosis was made when he presented with congestive heart failure.

Producion of efficient antimicrobial drugs against to common human pathogens is one of the most important challenges in the field of medical microbiology. Continuous screening of clinical isolates and survey of antimicrobial resistance pattern is critical.Today, disk diffusion and dilution methods are known as the common antimicrobial susceptibility Testing methods. Disk diffusion method does not render dependable results in determination of antimicrobial susceptibility pattern because this method is semi quantitative. MIC determination by microdilution and macrodilution techniques and recent method “E-Test”, have given interpretable results to researchers. Microdilution and macrodilution methods are also time consuming, expensive and error- prone methods. Whereas E-Test method is one of the means by which we will be able to determine susceptibility pattern of known species in low cost and short time. In this survey, constructing and printing of E-Test, coating of antibiotic on O.H.P film and quality control of constructed E-Tests were performed according to M7 A7 CLSI Standard. In this study quality of required materials for E-Test Production were suitable. Evaluation of constructed strips was performed using standard strain of staphylococcus aureus and reproducibly of results was appreciated.

Contact dermatitis is an inflammatory skin disease due to contact with different substances and caused by two mechanisms: allergy and irritation. Contact dermatitis is a common skin disease and the most common occupational dermatosis. Differentiating between allergic and irritant contact dermatitis is essential in the identification of etiologic factor(s) and hence, its control and prognosis. This differentiation can be done only by patch Test. Unfortunately, this simple, safe and useful Test is always neglected. We review the basics of patch Test, the method of performance, reading and interpretation of its results, possible side effects and results of studies done with patch Test in different countries.

Introduction: Root canal obturation seals the root canal system to prevent re-entry and/or growth of microorganisms. The provision of an appropriate restoration to coronally seal the access cavity affects the success of endodontic treatment. The purpose of this study was to evaluate the coronal microbial leakage in root canals that were either filled by lateral Compaction, GuttaFlow or warm vertical Compaction.aterials and Methods: In this ex vivo study, 80 single-rooted human extracted teeth were randomly divided into three experimental groups (n=20) and two positive and negative control groups (n=10). The teeth in experimental groups were obturated with cold lateral Compaction, GuttaFlow system or warm vertical Compaction techniques. After sterilization of the whole system with gamma-ray, saliva leakage was Tested using a split-chamber model.Specimens were monitored every 24 hours for 30 days. The data were analyzed using log-rank and Kaplan-Meier survival analysis Tests.Results: There were no significant differences in impeding saliva leakage between the three experimental groups (P>0.05).Conclusion: Under the conditions of this ex vivo study, it can be concluded that the sealing ability of cold lateral Compaction, warm vertical Compaction and GuttaFlow system was comparable.

For prevention of soil Compaction, knowledge of allowable compression stress limit (Compaction strength) in soil is important. Pre-Compaction stress ( spc ) was introduced as soil Compaction strength and often used as a criterion for evaluation of soil susceptibility to Compaction. In this research, pre-Compaction stress was measured for a sandy loam soil with plate sinkage (PST) and confined compression (CCT) Tests. To prepare soil samples with different initial compactness, two soil water contents (17 and 19%db) and six pre-loading stresses (0, 25, 50, 100, 150 and 200 kPa) were used. The effects of soil water content and pre-loading stress on estimated pre-Compaction stress were studied using a factorial experiment in a completely randomized design with three replications. The spc values were significantly influenced by loading combination and soil water content. For PST, pre-load increase and higher soil water content resulted in higher and lower values of spc , respectively. However, predicted spc value increased with higher soil water content for CCT. The results also showed that the spc predicted with PST was accurate, whereas the values obtained with CCT were 4.5 (at 17 %db) and 8.5 (at 19 %db) times higher than the applied pre-loads. Overall, the findings indicated that spc prediction depends on the compression Test, and PST could be a suitable method for soil pre-Compaction stress (Compaction strength) determination in sustainable soil management, i.e., soil trafficability and tillage. The PST method is also suitable to assess the effect of managing factors on pre-Compaction stress.

One important parameter in determining the allowable stress to prevent soil Compaction is preCompaction stress (σpc). If the stress induced into the soil due to agricultural machinery traffic is lower than the spc, the possibility of the irreversible (plastic) deformation is low. In this study, plate sinkage Test (PST) and confined compression Test (CCT) were used to determine the spc of the disturbed soil samples obtained from the topsoil of a long-term organic amendment experiment. In the organic amendment experiment, organic manures (sewage sludgeو compost, farmyard manure) at three rates (25, 50 and 100 t ha-1) and one inorganic fertilizer combination (250 kg urea ha-1 and 250 kg ammonium phosphate ha-1) were added to a silty clay loam soil for seven years under wheat-corn rotation. The effect of organic and inorganic fertilizers and gravimetrical water contents (17.1 and 20.9% db) on the spc values was determined using two statistical designs: 1) factorial design and 2) orthogonal contrasts in a completely randomized design with three replications. The spc values were estimated by the following methods: 1) Casagrande, 2) maximum curvature and 3) intercept of virgin compression line (VCL) with the x-axis at zero strain. The results showed that in both Tests, the spc values for treatments amended with organic manures had over-estimations and the values of the over-estimation were increased as the manure application rate increased. The values of the over-estimations for CCT were higher than for PST. Therefore, it can be concluded that the results of the PST are more reliable. The spc values estimated by any of the three procedures depend on the manure treatment as well as the initial water content of the soil. For determining the stress at the threshold of the Compaction for the un-manure soils (control and inorganic fertilizer) or the treatments amended with low application rate (25 t ha-1) of the organic manures, the PST and the Casagrande procedure can be recommended. In contrast, for the soils amended with high application rates (50 and 100 t ha-1), the PST and the maximum curvature procedure can be used.
