Control of Bruchidius incarnatus and Rhyzopertha Dominica using two entomopathogenic fungi alone or in combination with modified diatomaceous earth
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.

Total hip arthroplasty (THA) in the aseptic osteonecrosis of the femoral head in sickle cell disease
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.

Optimizing the Temperature of Cold-outlet Air of Counter-Flow Vortex Tube using Response Surface Methodology
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.

A Framework for Multi-Dimensional Perspectives of Green Practices in Construction Sector
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.

Effect of Salinity on the growth of petroleum hydrocarbons degrading Bacillus sp. isolated from chronically polluted ship breaking yards
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.

Study of biofilm formation by ESBL producing and non-producing clinical isolates of Klebsiella pneumoniae
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.
