The efficacy of diatomaceous earth (DEs) alone and combined with two microbial pathogens Nomuraea rileyi and Lecanicillium lecanii against two species, Bruchidius incarnatus and Rhyzopertha dominica was evaluated. Modified diatoms with Calcium hydroxide (Ca-DE) and modified diatoms with Sodium hydroxide (Na-DE) were the highlight treatments against tested insects and achieved the highest mortality percentages. Ca-DE was the most effective DE and accomplished the highest mortality percentages recorded 88% and 96% after treated R. dominica and B. incarnatus with 1.0%, respectively. The lowest mortality percentage was recorded in case of Al-DE at concentration 0.5% and amounted (21and 15%), for the corresponding species, respectively. Ca-DE and Na-DE were the most effective treatments in enhancing the potency of the tested fungi. The presences of DEs seem to have different types of impact on fungal potency. In most cases, DE combinations with tested fungi had synergistic effects, while Al-DE impaired the efficacy of N. rileyi against tested insects. Ca-DE has insecticidal, repellent and ovicidal effects against target insects. The current results revealed that both Ca-DE and Na-DE were the most effective DEs tested and they had synergistic effects on the potency of tested fungi.

Sickle cell haemoglobin is a very widespread in the world, constituting the most common hereditary disease. The evolution is enamelled of many complications including bone-joints, favoured by the emergence of new treatments improving the survival of these patients. The aseptic osteonecrosis of the femoral head is common in these patients. Was retrospectively analysed a monitored and treated in the service of trauma and orthopaedic of the Ibn Sina’s hospital in Rabat , 04 patients with sickle cell disease, who has submitted an aseptic osteonecrosis of the femoral head. It is 02 women and 02 men. The average age was 31 years. They had all consulted for hip pain and discomfort to walking. The clinical examination had found a limitation of movements. All our patients have benefited from a standard x-ray. Stage 3 Ficat is present in 2 cases and 4 stages in 2 cases also. MRI was carried out in a single patient. The operated hips have all received a total hip joint replacement, with satisfactory results in all cases. The aseptic osteonecrosis of the femoral head in the sickle cell disease is very debilitating, of fact the young age of onset and the late diagnosis.

To identify aspects of tuberculosis location of the greater trochanter and the adjacent soft parts, we conducted a study of 5 cases of tuberculous trochanterite collected in the trauma orthopedics Avicenne RABAT. There are 2 males and 3 females, mean age 45 years; this is a very latent disease that involves pain and swelling and sometimes a fistula. The radiograph shows specific alterations. The diagnostic confirmation is always based on the biopsy results will be sent to the bacteriology and pathology, and highlights specific lesions. The medical treatment is essentially based on anti-tuberculosis chemotherapy, most often associated with a surgical resection of the abscess pocket curettage of necrotic bone, removal of a fistula. The evolution under well led treatment is usually favorable, except in cases of infringement secondary hip which is a serious complication and is now becoming increasingly rare.

Vortex tube is a device that separates pressurized inlet gas into hot and cold streams. Its main applications are in spot cooling. Hence cold temperature of outlet gas, as a response variable, is of much concern for experimentation. There are various input controllable parameters, the values (levels) of which may affect the cold temperature of outlet gas. Some studies were carried out on vortex tube hitherto, considering different input controllable parameters. The present work analyses the effect of five input controllable parameters viz., inlet gas (air) Pressure, Length of the vortex (hot)tube, Diameter of the vortex(hot) tube, Diameter of the orifice / diaphragm, and Diameter of the nozzle on the response variable- Temperature of cold-outlet stream of air. Response Surface Methodology (RSM) approach is used to optimize the response. L-27 Orthogonal Array (OA) is used for experimentation. Response is of “Smaller the Better” type. Regression equation is obtained. All the parameters considered but the Length of the vortex tube, are found to be significant from the Analysis of Variance ( ANOVA ) table. Optimum levels for factors are predicted, confirmatory test is run and the experimental results are validated.

Concern about the outcome of human interaction with the environment has increased demand for environmentally friendly practices. Research on environmentally friendly practices indicates that green practices can be implemented at individual-firm-project levels. Changing the construction industry to a more environmentally friendly one requires a multi-faceted sequence at individual, project and organizational levels. Yet, there persists unclear understanding of the relevance of certain influencing factors at each of these stages. The aim of this paper is to advance a multi-perspective model of green construction practice. At the moment, there is a dearth of literature on the interrelationship of green practices at individual-firm-project levels. Thus, not much is known about the interplay of the three levels in influencing implementation of green practices in the industry. The present study, therefore, bridges the knowledge gap; and theorizes possible influences of interplay between the three dimensions of green practices. This is relevant to practitioners and scholars interested in green practices research.

Shot hole borer, Xylosandrus compactus (Eichh) is one of the most serious pests of robusta coffee. Small black beetle bore into green succulent stem and make galleries which leads drying of the twig. Ambrosia fungus grows inside the gallery helps the development of the beetle. Whole stages develop inside the gallery and this concealed nature makes it difficult to control. The present review discusses the distribution, taxonomy, biology and the control of shot hole borer.

Nowadays, controlling herbal pest and spraying operation are considered as important and inevitable activities in agriculture. In case the mentioned operation is performed in a proper manner and chosen a suitable sprayer, the cost of spraying and following operation will decrease and the yield will increase. Given the fact that Eurygaster Integriceps has been known as the most important pest of wheat which is a strategic product throughout the world, farmers use different sprayers in order to control this pest. In this study, micronair, electrostatic atomizer, atomizer, lance, and simple backpack sprayers were compared in the form of randomized complete blocks with four iterations, for controlling the Eurygaster Integriceps. The obtained data were analyzed through SPSS software. The results of the evaluation at the level of 5% revealed that, regarding the operation effect grade for controlling Eurygaster Integriceps pest, micronair sprayer with a 82.09% of died pest was at the highest rank, and electrostatic atomizer sprayer with a 75.88%, atomizer sprayer with a 72.40%, lance sprayer with a 66.60%, and simple backpack sprayer with a 62.58 % of died pests are at the next ranks. Given the obtained results in this study, for controlling Eurygaster Integriceps in the region of Kermanshah, micronair, electrostatic atomizer, atomizer, lance, and backpack sprayer were recommended, respectively.

Rather than a unattended (guardian less) is a individual problem it's a social problem. Today we are facing with abnormal increase of unattended children in all over the world. this increase have many reasons such as poverty, war, corruption and prostitution increasing and addiction … .These children are victims of society coarseness that not only deprived having parents and the kindly gathering of family but don't accept them and look at them as parasite. Although these children haven't different with their peers in intelligence but rate of self – esteem social growth and academic progress didn't grow like the children who enjoy feasibility family. The main purpose of this study is investigated educational and social status of unattended children in boarding institutes until investigated the organizational and structural status the care institutes of unattended children investigated the different their needs. This study was doing as descriptive and comparative study to the researcher be able describe care institutes children status and also compare them to peers in terms of educational and social. Study population consisted of all the unattended boys and girls that according to welfare organization's statistics they are 22 thousand and five hundred children who keeping in 480 institutes, selected 360 children and 20 institutes among them randomly.

The aim of this paper is to determine the effect of salinity on the growth of some previously known petroleum biodegrading Bacillus sp. under laboratory condition where petroleum hydrocarbons are the sole source of carbon.Bushnell-Hass (BH)mineral salt media consisting of different NaCl concentrations (0.0 to 0.4 mole/liter or ML^-1) were prepared and supplemented with 2% kerosene/diesel/engine. The media were then inoculated with the bacteria namely Bacillus pasteurii, B. badius, B. cirroflagellosus, B. circulans and B. brevisindividually. After 7 days of incubation, bacterial growth was determined by measuring the optical density (OD) of the media at 620 nm. We found that salinity has a great impact on the growth of the bacteria under investigation. A NaCl concentration ranging from 0.05 to 0.3 ML^-1was found to have a positive impact on the growth all 5 Bacillus sp.NaCl concentrations below and above the said range were found to be growth limiting.Interestingly our findings indicate that the maximum growth of a bacterium depends not only on the optimum salinity level but also on the type of petroleum hydrocarbons provided.The findings of this study are important for understanding the impact of salinity on the biodegradation process of petroleum hydrocarbons and to develop optimized application approaches to sweep such pollutants from contaminated sites.

This study was conducted to explore the biofilm forming capabilities of extended spectrum beta-lactamase (ESBL) producing and non-producing Klebsiella pneumoniae strains by three different methods and to compare the methods as well. Two ESBL producers and two non-producers strains were subjected to biofilm detection methods. These isolates were previously confirmed by standard methods and API (Analytical Profile Index) scoring. Their ESBL production capabilities were confirmed by double discs synergy test as recommended by the Clinical and Laboratory Standards Institute. Biofilm formation was detected by Congo Red Agar method (CRA), Test Tube method (TTM) and Microtiter Plate Assay method (MTP). Both the ESBL producing Klebsiella pneumoniae were characterized as strong biofilm formers. Between the two ESBL non-producers, one was assessed as weak and the other as moderate biofilm former by quantitative TTM and MTP. The MTP and quantitative TTM were considered superior to qualitative TTM and CRA method. Our findings highlighted the relatively higher biofilm forming ability by the ESBL positive Klebsiella pneumoniae that may additionally contribute to their resistance against extended spectrum antibiotics. We can conclude that K. pneumoniae strains, isolated from blood, to form biofilm have a significant association with ESBL production.
