In the Sahara, rangelands, offer favorable conditions for vegetation survival. The present study focused on estimating the diversity and determining the functional traits of spontaneous plants established in two Wadi beds, the Wadi N’Sa bed and the Wadi Mya bed, in the Ouargla region (northern east of the Algerian Sahara). For each Wadi bed, 23 phytosociological surveys were selected to study the diversity parameters, plant functional traits, and soil analyses to study the vegetation–soil relationships.\n The inventoried plants included 56 species, divided into 49 species from 24 families on the Wadi N’Sa bed and 15 from 10 families on Wadi Mya bed. The plant species are mainly therophytes (45%) in the Wadi N’Sa bed and chamephytes (60%) in the Wadi Mya bed. Phytogeographical analysis revealed the dominance of the Saharo Arabian element, which was 36.7% of the Wadi N\'Sa bed and 53.33% of the Wadi Mya bed.\nOur study revealed that the Wadi N\'Sa bed exhibited greater alpha diversity than the Wadi Mya bed, with ANOVA confirming significant differences between the two Wadi beds. As shown in the Principal Coordinate Analysis (PCoA) plots, the beta diversity further highlighted the distinctiveness between the two riverbeds and their respective sites.\nThe soil analysis of two Wadi beds allowed us to determine the relationship between vegetation and soil. psammophilous, halophilous, and gypsophilous species were predominated.\nSoil characteristics influence floristic composition diversity in sites of two Wadi beds and even between the two environments, and the distribution of plants according to the soil-vegetation relationship.

Recently, natural products of herbal origin have acquired great importance in protecting
against and curing many diseases as an alternative to chemical drugs that sometimes cause
many side effects. In this study, we focused on thymoquinone (TQ), a natural product
derived from black seed (Nigella sativa L.) that awards it its therapeutic activity. It has many
therapeutic activities such as anti-inflammatory, anti-microbial, anti-oxidant, anti
histaminic, immunomodulatory and anti-tumor activity. Other therapeutic benefits were also
encountered
as
gastroprotective,
nephroprotective,
neuroprotective
and
hepatoprotective activities. It has also cured diabetes, cardiovascular disorders, respiratory
ailments, reproductive disorders and bone complications. Thymoquinone protects the body
against diseases caused by oxidative stress as a phenolic derivative with a distinct antioxidant
activity by scavenging the free radicals and reducing the oxidative stress. It also protects
against the detrimental effects of nicotine on sperm count and sperm damage in rats. In this
review, we introduced some potent therapeutic activities of thymoquinone and illustrated the
most recent investigation reflecting its therapeutic effects. Recent investigations suggest that
clinical trials must consider TQ as a novel drug.

Human blood serum protein albumin (HSA) is well studied
protein owing its importance being a carrier molecule for
endogenous molecules, toxins, xenobiotics and other small
ligands like metal ions. The structure of protein is related to its
function and perturbations in structure reflect in function. In
the present study we studied the interaction of heavy metal ion
cobalt with human serum albumin. Present study reports
spectroscopic studies in presence of cobalt ion alone and in
presence of cosolvent. Here, we elucidated the interaction of
cobalt with HSA and role of glycerol as auxiliary solvent in
this process is evaluated. Cobalt interaction with human
serum albumin causes the aggregation of protein as indicated
by fluorescence emission increase, thioflavin-T (Th-T)
binding and scattering data also support the denaturation of
protein phenomenon in presence of cobalt. This study
evaluated the role of glycerol in denaturation of HSA in
presence of cobalt, It was observed that HSA incubated when incubate with glycerol was protected against cobalt induced
denaturation as indicated by loss of ThT fluorescence.
Glycerol is postulated to be an important auxiliary solvent in
protection of protein from heavy metal induced aggregation.
Heavy metals are present in environment and interaction with
humans is inevitable also metal ions in protein formulations
can cause protein denaturation. Prevention from exposure to
cobalt is important as interaction with proteins can cause them
lose function due to denaturation and aggregation causing
diseases and toxicity.

In today’s world, complex global business environment is in a state of continuous change. Therefore, business organizations are looking for an innovative way to optimize and to support the performance of their business processes to meet out their market share in order to maintain a competitive edge. Usually, business processes are monitored in near real-time using Key Performance Indicators (KPI). KPI is in turn calculated from metrics from business processes. In the case of business outsourcing, the KPI calculation from the metrics of business process is to be carried out cutting across the inter-organizations boundaries and spanning multiple domains. This process poses several challenges in the computation of the KPIs. Some of these challenges include uncertainty in metric values, just-in-time KPI computation and scalability. To address the above challenges of business organizations, a four-tier Complex business Activity Monitoring system with Event Processing (CAMEP) is proposed. The performance evaluation of the proposed system is performed to demonstrate the effectiveness of the proposed CAMEP method by comparing with the existing BAM approaches. The proposed CAMEP is also analyzed using the ANOVA and T test.

The paper carefully analyses the impact of information technology on business process re-engineering with respect to organizational perspectives. This study recommends an outline for simplifying business process reengineering efforts in the direction of competitive firms. The framework was examined using sample data from the respondents who are all senior officers. The review outcomes specify that managerial innovation, market force and competitive force positively affect information technology implementation, which in turn elicit variations or business process in terms of workroom, labor force and commercial structure. The work formulates hypothesis for the factors that affect implementation of information technology in an organization and thereby proposes a model for implications of results.

Mutual funds are moving rapidly towards financial market development in response to huge market demand in Iran.so what is needed is a useful and applicable method for appraising and selecting them. Performance evaluation is one the most important point in investment .therefore, in this research we tried to compute and compare the performance of mutual funds by different models and compare them to market. So we have chosen 14 active mutual funds during the year 2008 to 2012 and calculate the risks and returns of these mutual funds, then we analyzed hypotheses. Results show that performance evaluation of modern and postmodern theory gives different ranking. At this period some mutual funds showed better performance than market and some on the contrary .Also results show that postmodern portfolio criteria were more successful for predicting return than modern criteria. At the end results of research recommend the use of postmodern criteria which are based on downside risk.

In this paper, we solve the integro-differential equation by using new integral transform called Tarig transform. New theorems for the transform of integrals are introduced and proved.

The denoising procedure attenuates the image noise while preserving its edges and fine details. In computed tomography, images are degraded by additive white Gaussian noise because of different acquisition and systems errors. Due to noise existence, specialists may encounter certain difficulties to analyze or extract the useful information from noisy images. This paper presents a novel implementation of the phase preserving algorithm to denoise CT images. The phase preserving is a very powerful noise reduction algorithm but it tends to remove specific small details from the processed CT images supposing these details as noise. Therefore, the Wiener filter is used along with the latter algorithm to reduce the noise and aids in conserving the minor medical details. Moreover, selected adjustments to the phase preserving algorithm are applied to obtain a better image contrast and quality. The performance of the proposed scheme is assessed on naturally and synthetically degraded CT images using the universal image quality index (UIQI) metric. Results show major improvement not only in noise attenuation but also in preserving the small details.

In this paper, we present a reliable combined of Elzaki transform and homotopy perturbation method to solve Burger\'s equations. The analytical results of the equations have been obtained in terms of convergent series with easily computable components. The nonlinear terms in Burger\'s equations can be handled by using of homotopy perturbation method. The results tell us that the method is more efficient and easy to handle such partial differential equations.
