Perspectives for modern agriculture development in Romania

To understand the importance of this work, we must understand the importance of agriculture, in the Romanian space, in particular. Agriculture, as a primary field of activity including plant cultivation and animal husbandry, is a major sector of the national and global economy. Therefore, agriculture has to obey any rules, objectives and institutions that govern the economic system as a whole, whereas it is itself a distinct system that is interconnected with other subsystems within the economy. Modern agriculture begins in a research station, where scientists have access to the necessary supplies, expertise, and corresponding time. But, when the package is awarded to farmers, even the best farms cannot compare with the results we get as researchers. The basic challenge for modern agriculture is to sustain a better use of internal resources available in Romania. Presently, information in agriculture at the decision-making level comes from suppliers, researchers and private entrepreneurs rather than from local sources. However, the use of local information can minimize the use of external inputs, lead to more effective regenerating, or combine both. Modernization of agriculture presumes to be sustainable, economically viable, and socially responsible, protect resources, and serve as a basis for future generations. For this work, we have consulted some of the most important research literature, periodicals, scientific papers, technical and economic documentation, and other sources

The possibilities of using an outline crash sketch in modelling and simulation of accidents

The paper underpins the reconstruction and analysis of a vehicle - motorcycle-biker-assembly collision type by means of a graphical method. The virtual modeling of the traffic accident reconstruction was achieved by complying the traces and the distances identified; hence it was imported and developed the accident scene sketch. Following the numerical processing of the simulation, the vehicles speed during the pre-collision, collision and post-collision phases was determined in graphical form, generating speed and space variation diagrams.This work is published under NOCC (the "Licence").

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Przewodniki w środowisku kriogenicznym stosowane w energetyce

The tendency to increase the carrying capacity of the electric load in the supply networks can be done in two directions, namely: • the construction of several transmission and distribution lines linking the energy source to the consumer (current trend), having the effect of damaging the environment, or • limiting the construction of transport lines and, implicitly, the destruction of the environment by using technologies and materials capable of carrying a very large amount of electricity.Tendencja do zwiększania obciążenia elektrycznego w sieciach zasilających może być realizowana w dwóch kierunkach, a mianowicie: budowa kilku linii przesyłowych i dystrybucyjnych łączących źródło energii z konsumentem (obecny trend), powodujących uszkodzenie środowiska, lub ograniczenie budowy linii transportowych i w efekcie ograniczenia zniszczenia środowiska poprzez zastosowanie technologii i urządzeń zdolnych do przenoszenia bardzo dużej ilości energii elektrycznej

CONFIGURING THE STREET TRAM THROUGH THE AIMSUN SOFTWARE GRAPHICAL ELEMENTS

The transportation system is a complex, alive and dynamic mechanism. Taking into account all of the problems of a public transport the difficulty is to make a virtual network that can be improved and organized from the point of view of a systemic approach. Now, public transport is a critical point in urban development and should be treated as one of most important areas in a city. Public transport in the city is considered to be of great importance, in terms of social development and quality of life. In terms of city development, an important aspect is to create a public passenger transportation system that is safe, affordable, economical, reliable and environmentally friendly. The role of the public transport in economy and all aspects of the city development, from the point of view of the citizens, dictates the need to introduce measures in the system that are harmonious, balanced and effective and that can make the difference from development to stagnation
