Non-typhoidal (NTS) disease is usually a self-limiting infection presenting with digestive symptoms. However, disseminated presentation with involvement of secondary infectious sites is observed. We report diagnostic specificities and challenges related to the management of three patients with invasive NTS (iNTS) and secondary infectious locations. Among the seven patients (age range 46 - 83 years), four (two with extra-digestive infectious sites) had at least one immune debilitating condition. Two patients were incidentally discovered with iNTS and deceased after developing a septic shock despite antimicrobial treatment. Two individuals recovered under medical treatment without complications. Three other patients presented with secondary infectious sites. Case 1 suffered from urinary tract infection and dorsolumbar spondylodiscitis that responded well to antimicrobials and surgery. Abdominal prosthetic aortic aneurysm was diagnosed in case 2 and medical treatment only was applied. After four years of follow-up, he remains under antimicrobial treatment. Case 3 presented with conjoint thoracic aortic aneurysm and cutaneous abscesses managed with antimicrobials and surgery. Atherosclerosis and previous vascular intervention were the predisposing events for vascular involvement. iNTS is a serious disease carrying a high risk of mortality or secondary locations. Secondary locations can be managed by long duration antimicrobial therapy combined with surgery. Spine and aortitis are the most frequent secondary locations. Multi-drug resistant NTS represent an additional risk of mortality. Public health measures should be implemented to limit the spread of NTS to humans and the emergence of drug resistance.

We prove that, if F, G: 𝒞 → 𝒟 are two right exact functors between two Grothendieck categories such that they commute with coproducts and U is a generator of 𝒞, then there is a bijection between Nat(F, G) and the centralizer of Hom𝒟(F(U), G(U)) considered as an Hom𝒞(U, U)-Hom𝒞(U, U)-bimodule. We also prove a dual of this result and give applications to Frobenius functors between Grothendieck categories.

In this paper, we consider graded near-rings over a monoid G as generalizations of graded rings over groups, and study some of their basic properties. We give some examples of graded near-rings having various interesting properties, and we define and study the Gop-graded ring associated to a G-graded abelian near-ring, where G is a left cancellative monoid and Gop is its opposite monoid. We also compute the graded ring associated to the graded near-ring of polynomials (over a commutative ring R) whose constant term is zero.

We consider the category of near-rings and study some categorical permanence properties. We investigate the connection between the concepts of monomorphism and, respectively, epimorphism of near-rings and the concepts of injective and, respectively, surjective morphism of near-rings. We also present some interesting properties of epimorphisms in the category of near-rings.

By knowing the correct values of the parameters of maximal effort corresponding to the stages in the energy consumption of an individual's body, we can externalize the coordinates of the dynamic effort, i.e. the nature of the instructional objectives, the role of the exercises, the volume of work involved and the intensity and complexity of the effort. The major energy systems have also been connected with physiological parameters such as: heart rate, blood pressure, respiratory rate, etc. The evaluation of the students’ maximal aerobic capacity (VO2max) is thus a prior reference point in the optimal management of effort parameters in institutional sports activities. During a set of systematic programs of physical exercises, the heart “learns” to work economically both at rest and during physical activities of various intensities. As a result, the heart rate decreases gradually and the heart gets better at adapting to effort. This more or less guarantees heart disease prevention, optimizes cardiac input which involves the proper functioning of the cardiovascular system and of all the other organs of the human body. Besides inducing functional improvements, aerobic effort also develops muscle flexibility, joint mobility, coordination, it increases force, speed and resistance, thus improving the students’ overall physical condition through its aerobic functional components.

Developing the pupils’ aerobic capacity at this age influences their general physical condition and it makes the tiredness late. A better effort resistence will lead to a better recovery during the breaks between Physical Education classes and, what is more, it will determine pupils to better tolerate the increasing loads during these periods.The present study aims to point out the characteristics and the importance of training the aerobic capacity of children aged 8-10 years old. Moreover, we outline the functional benefits on children's bodies as a result of their aerobic-like efforts.The paper suggests a sequencing model of children's aerobic capacity development through different ways in terms of methods and techniques. To support this model we propose carrying out some evaluation physiological tests on relevant parameters for children's aerobic capacity. These tests can be easily applied and do not require special equipment.

The sporting game as the main branch of the Physical Education (PE) is activity-oriented to achieve motive performance as well as to develop positive behaviour and personality traits. The present study emphasizes the main influences on the 9-11-year-old children personality and behaviour through practicing sporting games. We initiated the applying of a sport program with instruction stages, certain objectives and methods, which aims to acquiring ethical conduct, confronting and managing different situations of success and failure, collaborating, communicating and developing the fair-play spirit. The program are applied to a number of 20 children, boys aged 9-11 years old, who are practicing basketball twice a week. The team sporting game leaves a special imprint on children's personality and will by requiring self-control and emotion-control in the team rivalry, the desire to win and the efficient solving of the game situations through initiative, cooperation and suitable motive actions.

By the microbiological action, lignin from vegetal wastes is transformed at soil level in organic prebiotic products with physiological activity on plants development. On the other hand, some micromolecular compounds resulted from plant wastes decomposition, along with polyphenols coming from extraction of plant residues could play a role of allelochemicals. The understanding of the allelochemical action mechanisms allow us to use these compounds to enhance crop production and develop a more sustainable agriculture, including weed and pest control through crop rotations, residue management and a variety of approaches in biocontrol. Other goals are to adopt allelochemicals as herbicides, pesticides and growth stimulants, modify crop genomes to manipulate allelochemicals production and better elucidate chemical communications between the components of ecosystem. The result obtained in the utilization of lignins and polyphenols as allelochemicals are presented in this review.

The study was conducted on a sample of children at the Lăpuş School with classes I-VIII, using the teaching/learning process of the biology disciplines. A key element in applying the theory of Multiple Intelligence in a classroom is knowing the intelligence profile of children. Differentiated teaching approach was designed based on the predominant types of intelligences. For this purpose we used various methods: questionnaire, observation of children as they are given various tasks, interview, development of projects, role play, the biographical method-personal history of child, analysis of activities' results (compositions, drawings, collages, portfolios), debates in pair-groups, and case studies. In child’s profile, (types of) intelligences become qualities that we capitalize in training, designing different teaching approach depending on predominant types of intelligences. The results appeared without delay. After a school's year that we worked differently with the children, they have improved school performance and became more interested in the study of biological disciplines thus arousing their curiosity and respect towards life.

The paper wants to analise the emissions removed by a diesel engine fuelled with biodiesel comparative with those eliminated if using a conventional fuel, especially the measurement of carbon quantity from the evacuated gases. For achieving these measurements, an opacimeter will be used, and the higher the opacity is, the higher is the amount of carbon. The measurements were made with the opacimeter through free acceleration between the slow no-load speed and the maximum no-load speed, at a normal functioning regime. Minimum 3 measurements of opacity at free acceleration are made. The results obtained after the experiments show that the opacity values of motor fuelled with biodiesel B 20 are smaller than those of motor fuelled with conventional fuels, at all measured speed values. On the other hand, other elements present in emissions, such as: CO Â 2 , Sulphure oxides, carbon monoxide and material particles are all smalller in the case of using biodiesel as fuel.

The paper presents the advantages of using biogas as an alternative source of energy, especially in rural areas and insists on its specific advantages, compared to other alternative fuels, such as bio-ethanol and bio-diesel, which are very significant fuels which can be used in the future, but are contested from the social point of view, because they use as raw materials plants, some of them being used as food sources for mankind. The main advantage of biogas is that it is obtained from residues and wastes, so it has the ability to transform waste material into a valuable resource in the conditions in which many countries are facing enormous problems associated with overproduction of organic wastes from industry, agriculture and households. Biogas production is an excellent way to comply with increasingly restrictive national and European regulations in this domain and to use organic wastes for energy production, which is followed by recycling of the digested substrate as fertilizer. In the paper is emphasized the fact that a biogas plant is not only a supplier of energy. The digested substrate is a valuable soil fertiliser, rich in nitrogen, potassium, phosphorus and micronutrients, which can be applied on soils with the usual equipments for application of liquid manure. A wide range of biomass types can be used as substrates for the production of biogas. The most common biomass categories used in European biogas production are : animal manure and slurry, agricultural residues and by-products,  i€ digestible organic wastes from food and agro- industries, organic fraction of municipal waste and from catering, sewage sludge, dedicated energy crops (maize, miscanthus, sorghum, clover).  One main advantage of biogas production is the ability to use “wet biomass” types as feedstock, all characterised by moisture content higher than 60-  70% (such as sewage sludge, animal slurries, flotation sludge from food processing etc.). In the late years, a number of energy crops (grains, maize, rapeseed), have been largely used as feedstock for biogas production in countries like Austria or Germany. Besides energy crops, all kinds of agricultural residues, damaged crops, unsuitable for food or resulting from unfavourable growing and weather conditions, can be used to produce biogas and fertiliser. A number of animal by-products, not suitable for human consumption, can also be processed in biogas plants.

The paper presents some researches on using sugar beet for producing bio-ethanol, considering the advantages which this raw material presents compared to other materials from which bio-ethanol can be obtained. One of the reasons of using bio-ethanol for motors as a fuel is the goal to reduce of 20% of greenhouse gases and it is established that the emissions of CO2 are much reduced in the case of bio-ethanol than that of conventional fuels.

The alternative fuels are substances or materials used as fuel, other than the old conventional fuels (oil, natural gases and coals). The paper analyses the most important alternative fuels, such as: bio-diesel, alcohols and hydrogen, presenting at each category the main important characteristics, the advantages and disadvantages presented by them. The methyl-ester which is known as bio-diesel can be used in all motors with ignition by compression, alone or mixed in any proportion with oil, with minor modifications at the injection system. Bio-diesel fuel assures the same motor power as oil does, having even a bigger cetanic number than the usual oil. After tests, it was observed that the consumption is also similar, at the same motor performances. The bio-diesel fuel has very good lubricant properties, such as its adding to oil leads to a better protection of the pieces in motion of the motor. The second alternative fuel analyzed are the alcohols. The most used primary alcohol is the methanol, the most simple secondary alcohol is izo- propane and the most simple third alcohol is third-butanone. The most used alcohol as fuel is the methanol and the ethanol. The methanol presents some disadvantages such as: the tendency of reducing the effective power, a big delay at self-ignition, the unfavorable properties of oiling, the reduced capacity of mixing with petrol fractions. Finally, the paper presents some researches made on using hydrogen as fuel for auto vehicles motors.

It is necessary today to increase in Romania also the efforts to research in direction of identifying those biosystems which are hyperaccumulators for heavy and rare metals in order to be used as instruments in environmental clean biotechnologies as well as bioindicators or metal sources. In USA and Australia the researches in this way are extended over all common species of mushrooms (macromycetes). That is the reason we determinated the chemical content in metals of some macromycetes (mushrooms) species which are autochthonous in forestry ecosystems of Dambovita county. We begun a large study in this aria, but in this paper we present a study about two species very common in our forestry ecosystems - Armillariella mellea and Macrolepiota procera. In the same time we made the analyses of soil elemental content under macromycetes studied. The determinations were made by spectrometry advanced method in our own laboratories by ElvaX spectrometer. The resultes show a large elemental content in soil, but the content over 1ppm in bioelements, heavy and rare metals as number in two macromycetes species is a limited one. Everyone of two macromycetes species contains heavy metals (Fe, Cu, Zn) and rare metals (Re, Os).
