The high Algerian steppe plains are currently experiencing a strong tendency toward soil degradation, disrupting ecological and socioeconomic balances. The reassignment of these soils in woody agrosystems with a local plant component undeniably offers positive externalities for these rural regions. Most studies concerning this action focus on the visible part of biodiversity, mainly on plant species, and few have been conducted on the microbiome associated with them and its structuring at the rhizosphere and the phyllosphere level after reassignment. In this study, we compare the diversity, richness, and abundance of fungal genera identified at the rhizosphere and phyllosphere level of a pomegranate cultivar from the Messaad region (Djelfa, Algeria) to understand their dynamics. Sampling was conducted on twelve vigorous and healthy trees during the summer season (July 2018). After isolation and microscopic identification, we noted a fungal diversity belonging to two phyla: Ascomycota and Mucoromycota, with a dominance of the first phylum in the two compartments. Fungal strains indicate a high abundance of the genus Alternaria in epiphytes and endophytes. The genera Aspergillus and Rhizopus are the most dominant in the rhizosphere. The dominant fungal genera of the two compartments are melanised. The ShannonWiener diversity and uniformity indices show higher values in the phyllospheric compartment compared to the rhizospheric one. However, the similarity is higher between the diversity of the rhizosphere and the diversity of the two micro-niches of the phyllosphere than that displayed between the two microniches of the latter. The principal component analysis differentiated along axis 1, the rhizosphere from the phyllosphere, each with its procession of fungi. Axis 2 distinguished the endosphere from the episphere, with a fungal procession specific to each micro- niche.
It is impossible for companies to achieve success and preserve it via traditional methods. Today, managers cannot make decisions based on a series of fixed rules, traditional policies and simple conclusions. They need to consider new policies and strategies at the time of planning and determining corporate objectives. Therefore, balanced scorecard model (BSC) is a new attitude for implementing strategies in organizations. This model measures organizations’ motivations and determines the indexes which need to be assessed and the actions which need to be considered. This paper studies how to use this new attitude based on a dynamic and providential mind for arriving at strategic management. The results show that BSC model is the best strategic management method and lets organizations be creative and innovative and also try actively for the future of organization.
An enzyme linked immunosorbent assay (ELISA) system was developed to detect antibody to bovine viral diarrhoea virus (BVDV) in bovine sera. This study was done by utilizing NDAL strain of BVDV and MDBK cell line as antigen. The home-made ELISA system was developed and the results of total 99 sera involve field sera and used sera for biological production were compared with a commercial ELISA kit. Result showed a high reproducibility. According to this study sensitivity, specificity was 88% and 53%. Agreement for field sera and used sera for biological production were 49% and 93%. The results, where costs are issue and the absence of more commercial diagnostic test in developing countries, indicate that in house ELISA system can be valuable for use in primary screening and select suitable sera for biological product.
Theoretically the present study conceptualizes the idea of “third place” in local libraries. Widespread adaptation of environmental services and comfortable sitting place has generalized library as a pleasurable place. Discussing the social theories of location, in the present study we follow that the context of “third place” has changed during the time and whether we can call libraries as third places. Methodology of the present research is qualitative to great extents. Designing interviews with libraries heads considering their practical purposes and using a firm concentrated group to discuss and speak with users was done in relation with their experiences. However this study draws quantitative information in the form of face to face questioning and answering and addressee-based considerations. Generally the results of the present study showed the main purpose of the discussions which is creating and changing a place to a third place. While the experience of user to local libraries has been usually positive and have received an enjoyable experience from the environment, these places can’t be called third place because they don’t have chat among themselves. The important and notable point is that designing an interior coffee shop attends the issue of socialization among the users of the libraries more. The study’s scope is limited to local libraries in Iran. Future research should study the concept of third place in different cultures and bigger societies and provide suggestions and strategies for heads of libraries considering the environmental potentials of the place.
In this research, we investigated Calcium (Ca) and L-Histidine (His) interaction on Nickel-induced oxidative stress tolerance in two tomato (Lycopersicon esculentum Mill.) cultivars including Cal-J N3 and Petoearly CH. For this, we compared CaCl2 (0 and 300 µM) and L-Histidine (0 and 300 µM) effects on the oxidative responses in these cultivars cultured in the hydroponic media under Ni stress (NiSO4; 0,150 and 300 µM). Activities of antioxidative enzymes including Catalase (CAT), Guaiacol Peroxidase (GPX), Ascorbate Peroxidase (APX), Superoxide Dismutase (SOD) and content of total Protein, Malondialdehyde (MDA), other Aldehydes, H2O2, Ca2+, Ni2+, Ascorbate (ASC), Dehydroascorbate (DHA) and electrolytes leakage (EL) were determined. Results showed that Ca and His reduced generally oxidative markers such as EL, H2O2, MDA and CAT activity, root and shoot Ni2+ content under Nickel toxicity while Ni alone increased these oxidative parameters and Ni2+ accumulation compared to the control. Ni-applications without Ca and His decreased GPX, APX, SOD activities, root and shoot Ca2+, ASC in the cultivars. Ca and His elevated Ca2+, ASC content, GPX, APX, SOD activities and inhibit Ni2+ accumulation differently in both cultivars. Ca and His also alleviated the adverse effects of Ni stress on all parameters especially in Petoearly CH cultivar. Thus, Ca and His interaction appeared to improve adaptive responses to Ni stress leading to decreasing Ni-induced oxidative stress in the tomato plants. Therefore, our results suggest that Ca and His alleviate Nickel-induced oxidative stress by Ni2+ uptake and translocation inhibition and also Ni chelating mechanism promoting in the tomato cultivars.
The feeding sequence and the initial concentration ratio of reactants were varied in order to investigate their influence on decreasing mean particle size and morphology of BaSO4 particles in a semi-batch stirred-tank reactor. The experiments were carried out via a simple precipitation reaction of sodium sulfate with barium chloride in a semi-batch reactor. Either BaCl2 or Na2SO4 as a limiting reactant of concentration 0.1 M was added to the tank containing the opposite component at a concentration from 0.1 to 1.6 M. The samples were characterized with particle size analyzer (PSA) and scanning electron microscopy (SEM). It was found that varying ionic ratios (Ba2+ to SO4 2- (R)) leads to a significant change in particle size. The impact of feeding sequence (BaCl2 or Na2SO4) was generally rather small.
Today’s modern world has numerous targets to be completed where the clock dial is shortened. People are having and different attitude and behaviour in the way they deal with the problem and providing the solutions. The culture place a major role in which the people are grown with different Ego and Super Ego stages that helps in molding the attitude which shapes the social Intelligence behaviour. The Conflict arises when one thought process is been rejected or unacknowledged in due acceptance. The arise of conflict reason when one needs is not fulfilled by the other. Conflict can be also termed as a personal or group orientation, such as interpersonal, intrapersonal, intergroup and intragroup conflict (Rahim, 2001)1. My study focus on the IT and ITES employees on Emotional Intelligence with the conflict management in Coimbatore Region. The present study evaluates the EI and conflict patterns among the employees. The questionnaire used in the study to measure the conflict style is “Conflict Resolution Questionnaire “(CRQ) presented by weeks (1994)2 and fisher and Ury (1991)3 and to measure the Emotional Intelligence (WLEIS scale) presented by Wong and Law (2002) [12]. The respondents were selected using convenient sampling. The respondents selected where the employees of IT and ITES people in Coimbatore region. The collected data is studied through the Statistical Tools using SPSS. Hypothesis where framed to test the conflict styles among the respondents. \nThe result has shown difference among the respondents on the Level of Emotional Intelligence and conflict Styles. The study shows the factors on demographic various in the conflict Resolution and few insights had been derived from the research work. The study recommends on experimental design which helps in to find methods to resolve the conflict in an innovative way.
A low profile, compact slotted patch antenna has been designed using finite element method based high frequency full-wave electromagnetic simulator. The proposed antenna fabricated using LPKF printed circuit board (PCB) fabrication machine on fiberglass reinforced epoxy polymer resin material substrate and the performance of the prototype has measured in a standard far field anechoic measurement chamber. The measured impedance bandwidths (Reflection coefficient <-10 dB) 1.9 GHz (14.3-16.2 GHZ), 1.5 GHz (17.4-18.9 GHz) and 0.6 GHz (19.2-19.8) have achieved from the proposed antenna prototype. Maximum gains of 9.4 dBi, 6.87 dBi and 6.82 dBi have measured and simulated radiation efficiencies 80.3%, 81.9% and 82.5% have achieved at three resonant frequencies 15.15 GHz, 18.2 GHz and 19.5 GHz respectively. Minimum gain variation, symmetric and almost steady measured radiation pattern shows the proposed antenna is suitable for Ku and K band satellite applications.
This study investigates the genetic divergence between Vietnamese Macaca mulatta and Myanmar Macaca mulatta, revealing a total of 704 nucleotide differences. Notably, the protein-coding gene nad1 exhibits 38 significant variations, primarily characterized by the substitution of cytosine (C) in the Vietnamese population with thymine (T) in the Myanmar population. Additional differences are noted across several other genes, including nad2 (40 differences), cox1 (59 differences), and nad4 (76 differences), among others. Importantly, there are no nucleotide loss mutations, indicating that all differences are substitutions. The substantial genetic variation underscores the evolutionary adaptations of these populations to their respective environments. Furthermore, 60 differing positions in the control region highlight potential regulatory changes in mitochondrial gene expression, suggesting that environmental factors have significantly influenced the genetic makeup of these primate populations.
