In this paper, we discuss about some applications to the birth and death process in biology and in the theory of waiting. First, we introduce some theoretical notions about the stochastic processes and we define the Markov chain and the Poisson process. Afterwards, we consider two processes of birth: "The Poissonian tide of particles” and “ The Yule-Furry process”, that have multiple applications, the theory of waiting being one of them. Finally, by using the theoretical concept presented above, we solve two examples: the first is a problem from veterinary medicine, and the second one is an example of the model M/M/1 from agriculture, which means if the entrance, the time of serving and the number of stations are given, we'll calculate the number of the biological units in system, the medium number of the applicants in line and the medium time of waiting.

The development of the rural area, of the rural community respectively, constitutes a complex and uptodate research subject because it relies on two basic elements closely interdependent: the source of sustainable resources that may generate development and, the inhabitants of the rural area reprezenting both factor of action and consume as beneficiaries of the development. In this context, the present approach to conduct research leading to the design of strategic options for the development and diversification of the rural economy according to the principles of bio and ecoeconomy is justified and will try to meet the challenge of identifying those elements that lead to integration of the main activities in rural areas (agriculture, aquaculture, fishing, forestry, manufacturing, etc..), and to diversification of the rural economy while maintaining a balance between the need to preserve and promote rural tradition and impending modernization of rural life. It catalyzes the need to identify specific solutions to rural development imposed by its characteristics, by the change across all activities in rural areas and frequent reorganizations, or continuous adaptations to cope with changes produced both in and outside the countryside and which evolve over time and are characterized by dynamic random or unpredictable new elements.

The study was designed to assess the strengths and weaknesses of e-wallet innovation system of agricultural input distribution among farmers in Osun State, Nigeria. A multistage stage sampling procedure was used to select the respondents. Data were gathered through structured interview schedule from 324 farmers randomly selected from four Local Government Areas of the state. Data collected were analyzed using appropriate descriptive and inferential statistical tools. The results showed that the respondents had a mean age of 44.1 years with majority (74.1% and 94.4%) were male and married respectively. The mean household size of the respondents was 9 persons. Removal of corruption on fertilizer (mean=2.53), access to fertilizers at subsidized price (mean=2.35), quickened access to improved seeds (mean=2.27) and elimination of exploitative activities of middlemen in fertilizer supply (mean=2.21) were the major strengths of the scheme. While low quantity of fertilizers allocated to farmers (mean=3.17), late supply of inputs (mean=3.05), poor mobile network for e-wallet (mean=3.02) and low level of awareness of e-wallet by farmers (mean=3.01) were the prominent weaknesses of e-wallet. It is therefore recommended that successive government should continue and improve on the approach by addressing the identified weaknesses since the system has great potentials for sustainable agricultural development in the nation.

The paper describes changes observed in Romanian agriculture from 2002 until 2016, against the background of the situation in previous years. Romania’s membership in the European Union has substantially changed the farming conditions in Romanian agriculture. Thus, the question arises: what has changed in that sector in recent years? The present article contains an attempt to answer this question. Therefore, the main of this article is to describe the agricultural holdings situation and evolution in 2002-2016 period using data from the Agricultural Census (2002, 2010 years) and Farm Structure Survey (2005, 2007, 2013, 2016 years). During the 2002- 2016 period, the number of agricultural holdings has been declining. It shows that the large agricultural holdings which represent 0, 5% of total agricultural holdings manage more than 50% of utilised agricultural area. The situation of Romanian agriculture has improved substantially and it is characterised by a traditional farming which is the most dominant in terms of numbers of people involved and the geographical coverage. In Romania agriculture is an important contributor towards national economic performance.

After the Accession to the European Union the Common agricultural policy become an important factor for the development of Bulgarian agriculture. Despite the positive changes in the sector, the agrarian production in the country is characterized by low competitiveness and efficiency. The aim of the study is based on the analyses of the structural changes in Bulgarian agriculture to formulate conclusions for the effect of the ten years membership on the sector. The paper outlines the transformations in agricultural production, farm structure and trends in trade with agricultural products. The study indicates that there are significant problems related to productivity and value added over the past 10 years. The main challenges are associated with structural and sectorial imbalances, uneven distribution of financial support, polarization and overconcentration in the sector.

The paper presents a synthetic overview of total milk production, discussing the main components (cow's milk and buffalo, respectively sheep's milk and goat's milk). Reference is also made to the national level of the indicators so as to achieve a spatio-temporal positioning of the analyzed region and of its component counties. It is noted that the South - West Oltenia Region does not exceed 12.50% for any analyzed indicator. Dolj county is the most important regional milk supplier and Mehedinţi County represents the administrative territorial unit with the lowest contribution to the regional level of the indicator.

In this paper we have analysed the determinants of the students’ leisure time, based on 198 respondents of an questionnaire. The students are at the bachelor level in the Faculty MIEADR, USAMV Bucharest. The questions have reffered to the conditions in which students used to spend their leisure time. The performed analysis consisted in several steps. First, we made a descriptive analysis of the variables, by doing the frequences tables; then, there were performed correlation tables and the crosstabulation between pairs of variables. In order to verify the level of the statistical significance among the variables, it was also performed a chi-square statistical test. As general requirement, we have chosen to emphasise the results by pointing out the influence of the gender and place of residence variables for the respondents. From the findings of this paper, we have concluded that students of our faculty have different approaches, divided by place of residence regarding the holidays spend abroad. Meanwhile, by taking into consideration the gender, we got significant results regarding the responses on level of disponible revenus (a), the average spending amount by stay (b) and on the persons that accompanies the respondent student during the holidays (c). There were other results reflected on the level of Pearson coefficient on correlations between variable regarding the average lenght of the stays, the averge amount spend on accommodation and food etc.
