Calculation of electron correlation energy in molecules involves a very important computational effort, even in the simplest cases. Nowadays, using the new parallel libraries (PETSc and SLEPc) and MPI, we can resolve this calculation faster and with very big molecules. This result is a very important advance in chemical computation.

In this study, five kinds of metal salt were selected, and Span80 and Tween80 surfactants were selected; they have been used in wide range of hydrophilic–hydrophobic balance (HLB) from 4.3 to 15. The electrical conductivities of heavy oil and different brine emulsion were measured. The objective of this study was to investigate the effect of HLB on the conductivity of heavy oil-brine emulsion. A series of brine-in-heavy oil type (w/o) emulsions with various HLB were prepared. This test used the ...

This study was performed to compare the growth dynamics of Serretia in single and coculture biofilms condition and also evaluated its antagonistic effect against pathogenic bacteria. One preserved isolated subculture was identified on the basis of their morphological, cultural and biochemical characteristics. The isolate was belonged to the genus Serretia and provisionally identified as Serretia rubidaea. This isolate was exposed to different environmental condition. The experiments were carried...

A constant challenge for Greek primary EFL teachers is the large number of spelling mistakes in their learners’ written performance. Teachers usually feel helpless in understanding and remedying this problem due to non-existent research outputs in the realm of the spelling of Greek young EFL learners. Within this context, the researcher was stimulated to study the particular problem as an English teacher and educational researcher working on SLA. A descriptive case study was conducted into the s...

The Lemierre’s syndrome (coexistence of oropharingeal infection, septic thrombophlebitis of the internal jugular vein and septic embolisms), rarely can be caused by Staphylococcus methicillin sensitive, showing a great virulence because of their capacity to produce a toxin called “Panton-Valentine Leukocidin”. We present the case of a patient who was admitted to our ICU with a clinical picture of septic shock secondary to this syndrome, in which this pathogen was found as the etiologic agent.

Background: Many studies have found that vitamin D deficiency is associated with impaired human insulin action, suggesting a role in the pathogenesis of diabetes mellitus type 2 (T2DM). This study investigated the effects of vitamin D3 supplementation on serum HbA1c values and 25(OH) vitamin D concentrations in healthy and diabetic individuals. Methods: 722 individuals aged from 36 to 61 years old were selected (360 males and 362 females) divided into two groups. Healthy male group consisted of ...

Tomato is one of the vegetable crops growing in Ethiopia and important cash crops for small scale growers with a potential for increasing incomes in rural areas, improving the living standards and creating employment opportunities for women and youth. Vegetables in tropical countries are the crops which are often attacked most seriously by arthropod pests. Among the major insect pests, white flies, one of a serious leaf-sucking pest, cause direct damage to plants by sucking plant sap. The experi...

This research describes a new design of hollow fiber solid-liquid phase microextraction (HF– SLPME) which was developed for the extraction and measurement of Cu(II) ion in water samples combined with atomic absorption spectroscopy. This method consists of an aqueous feed and the functionalized multi-walled carbon nanotubes (F-MWCNTs) with HNO3 and NaClO, dispersed into n-octanol, are held within the pores and the lumen of a porous hollow fiber as the extractor phase. The presented method allows ...

Ethiopia is the largest chickpea growing country in Africa. Most of the chickpea production is used for domestic consumption as well as for substantial export. However, the national average grain yield in Ethiopia has remained extremely low and owing to different biological and physical constraints. Among these, insect pests have special influence on low level of production and productivity. Cutworm (Agrotis spp.) is one of the important pests of chickpea during seedling stage in Ethiopia and fe...
