Organizational Wellness Modeling

The aim of the present paper is to establish certain mathematical models for organizational wellness as well as to create some wellness optimization problems applicable to any type of organization (including universities) that might be mathematically solved resorting to aspects of operational research of mathematical analysis. The results obtained associated with a mathematical apparatus enable one to perform analyses, comparisons, interpretations, predictions. All of us have, consciously or not, a genuine curiosity in creating and shaping organizational wellness. This concept represents a highly topical issue since professional activity, irrespective of its field, holds a very significant place for each of us. The hard-to-dinstinguish „border” between personal and professional life urges all companies, smaller or larger, to attempt to find solution at an individual and organizational level in order to support and improve the concept of organizational wellness, in its current and future understanding. Regardless of their thoughts, feelings or actions, all individuals belong to that organization.organizational wellness; mathematical models; social processes modelling.

Cognitive impairment in HIV and HCV co-infected patients: a systematic review and meta-analysis

Cognitive impairment has been well documented in human immunodeficiency virus (HIV) and hepatitis C virus (HCV) mono-infections. However, in the context of HIV/HCV co-infection the research is more limited. The aim of this systematic review was to describe the characteristics of cognitive impairment in HIV/HCV co-infection and to examine the differences in cognitive performance between HIV/HCV and HIV and HCV mono-infected patients. Of the 437 records initially screened, 24 papers met the inclusion criteria and were included in the systematic review. Four studies were included in the meta-analysis. Most studies indicated that HIV/HCV co-infected patients had a higher level of cognitive impairment than HIV mono-infected patients. Meta-analysis also indicated that HIV mono-infected patients had a significantly lower global deficit score than co-infected patients. The results also indicated that co-infected patients were more likely to be impaired in information processing speed than HIV mono-infected patients. These findings can be challenged by biasing factors such as the small number of included studies, heterogeneity of the samples and a large diversity of methodological procedures. Future research with consistent and comprehensive neuropsychological batteries and covering a greater diversity of risk factors is needed, in order to clarify the effects of both viruses on cognitive function and the mechanisms that underlie these effects. Because cognitive impairments may pose significant challenges to medication adherence, quality of life and overall functioning, such knowledge may have important implications to the planning and implementation of effective interventions aimed at optimising the clinical management of these infections

Operating behavior of the irrigation system under OUAI AQUA NORTH SOLONEŢ BIVOLARI

The need to rehabilitate and modernize the old irrigation facilities is even greater, due to the fact that most irrigation systems were built before 1989, respecting the functional parameters of that period. Even if some of them have operated at minimum capacities or have been exploited only on certain sections, the physical and moral wear and tear do not allow their exploitation in conditions of maximum efficiency. The opportunity to rehabilitate the old irrigation systems comes with the launch of the National Program for the Rehabilitation of the Main Irrigation Infrastructure in Romania, by PNDR, in 2007. A series of Organizations of Water Users for Irrigation (OUAI) benefited from European funds, submitting financing projects, this being also the case of OUAI AQUA NORTH SOLONEŢ BIVOLARI, from Iasy County. The necessary funds were obtained for the rehabilitation of the Pumping and Pressurization Station SPP 1.b. by Measure 125 a1. Since the commissioning, in 2014, and until now, no malfunctions of the water network and distribution have been registered, nor on the other components of the station. Rehabilitation works were designed, executed and maintained rationally, so that no malfunctions occurred. After the rehabilitation of the irrigation system, production increases were obtained for the corn crop of 6.67% -38.48%, depending on the climatic conditions of the analyzed years

Technical and functional characteristics of the irrigation system from S.C. Livada mere de Iteşti s.r.l. Bacău

High-performance agriculture is achievable based on investment: starting from a high-quality seed or propagating material, ensuring optimum conditions for growth and development to reach, in the end, a higher value for production. By providing the crops and plantations with the water need, a significant increase in productions obtained. To this purpose, it is necessary to invest in irrigation systems, because the annual rain fall is not sufficient or we do not benefit from it in the critical phenophases of the crops. In the fruit-growing farm SC Livada mere de Itesti SRL Bacau, the drip irrigation system, which is currently considered the best method for irrigating the orchards, is installed. Designed on an area of 17 acres cultivated with apple trees, of different varieties, the irrigation system consists of: front assembly, transport-distribution pipe, connecting pipes, and watering pipes provided with droppers. By accessing European funds, through the PNDR, it was possible to make are conversion investment of the fruit plantation, to equip it with a drip irrigation system, as well as to modernize the fleet of agricultural machines and equipment. The work aims to present an irrigation development model, a model successfully implemented, thanks to the funds

Nanoparticle/biopolymer-based coatings for functionalization of textiles: recent developments (a minireview)

[EN] This minireview presents recent developments in surface nano-structured textiles and their biomedical applications by up-to-date achievements, summarizing the coatings made of biopolymer films and nanoparticles on different textile substrates for enhanced medical applications, diminishing the incidence of the multiple range of hospital-acquired infections in the past 10 years. The combination of metal and metal oxide nanoparticles with biopolymers is an efficient technique to generate enhanced antibacterial, virucidal and antifungal properties to textiles. Only a few review articles offer a comprehensive insight into the surface tailoring of textiles by nanoparticles-biopolymers use as an alternative for surface modification of textiles, granting them biocidal performance. The overview points out the compelling reasons for scientists and experts to enhance the already existing results in the biomedical textiles domain, with an emphasis on antimicrobial responsivity, highlighting: (a) the benefit of the simultaneous nanoparticles-biopolymers deposition on textiles by various deposition techniques, meaning the wash fastness of the antibacterial attributes and the biocompatibility of the material in comparison with only nanoparticle coating; (b) the use of biopolymers to stabilize colloidal dispersions of nanoparticles, granting the nanoparticles functionalities for covalent immobilization on textiles with long-lasting antibacterial effect; (c) the most usual metal and metal oxide nanoparticles and biopolymers for antibacterial textile applications.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The project was financed by Lucian Blaga University of Sibiu and Hasso Plattner Foundation research grants LBUS-IRG-2021-07.Vrinceanu, N.; Bucur, S.; Rimbu, CM.; Neculai-Valeanu, S.; Ferrándiz Bou, S.; Suchea, MP.

The efficacy of different irrigation levels on the yields of some summer crops under intercropping systems

Field studies were performed between 2014 and 2019 on clay soil in a farmer's field in Al - Yadudeh area south of Amman - Jordan, to investigate the efficacy of different irrigation levels (0.40, 0.60 and 0.80 of field capacity) on the yields of bean, squash and okra as they are grown under sole cropping and intercropping systems, using 1:2 and 2:1 row arrangements. Results showed that the highest significant yields of bean (10.20 ton ha-1 ) and squash (37.05 ton ha-1) were obtained when minimum soil moisture level was maintained throughout the growing season at 0.60 of field capacity (FC) under 1:2 intercropping row arrangement, while the highest significant yield of okra (13.64 ton ha-1 ) was registered when it was intercropped with bean in 1:2 row arrangement at minimum soil moisture level of 0.80FC. Additionally, okra intercropped with squash affected each other negatively and obtained the lowest significant yields specially, when they were grown under minimum soil moisture of 0.40 FC in 1:2 and 2:1 row arrangement respectively. Moreover, the highest significant yields of bean, squash and okra, as they are grown under sole cropping were obtained at minimum soil moisture level of 0.80FC, as compared to minimum soil moisture level of 0.40 and 0.60FC. It seems that squash was more beneficial to bean than okra and bean was more beneficial to okra and squash than squash to okra and okra to squash. Regarding the efficiency of intercropping as it was evaluated by land equivalent ratio (LER), the results showed that all the three combinations of intercropping with their row arrangements and under the three soil moisture levels gave LER values more than one, demonstrating the superiority of intercropping than sole cropping
