This research article is based on a study of optimal frequency to the repairable system due to the failure finding interval to maximize as well as minimize the availability of some components devices. We studied together maintenance and corrective actions that carried out item of failure and periodic failure finding designed to check whether a system is still working. The model is proved as well as useful application in detecting the problem related to finding failure tasks of different scheme devices by maximization. The model formulated and the numerical application to the relevant mathematical model have been discussed to demonstrate the article quality. Therefore based on probability analytic development, the optimal maintenance policy is then obtained as solution of an optimization problem in which the maintenance cost rate is the objective function and the risk of corrective maintenance is the constraint function. Finally, the solution to the optimal device in the considered development model has been well adjusted due to derivation to the experimental observation rather than theory which will be taken into consideration in the next applied practical design research related and the system device provided that, the proactive device agreed with using the exponential distribution to the survive distribution function which can not be considered as valid.

Honey harvesting throughout beekeeping is a technology recently introduced in Gabon comparing to the other African countries well known in international honey trade. The purpose of this study is to contribute to the knowledge of the quality of multi-flower honeys from the savannah-gallery forest complex and primary forest not well documented in Gabon. Physical and chemical parameters of different honeys were analyzed using the official methods of analysis of the Association of Official Analytical Chemists. The results of physico-chemical analysis show variations in pH (3.4 to 3.9), free acidity (37.12 to 76.65 meq∙kg−1), water content (17.49% to 21.21%), electrical conductivity (0.64 to 1.24 mS∙cm−1), density (1.02 to 1.03) and total sugar content (77% to 82%). These variations were significantly different (p < 0.05) between certain honeys, but independent of the type of ecosystem considered. The pH values confirmed the botanical origin of the five honeys. The physico-chemical parameters of the honeys show significant correlations (p < 0.05). Moisture content is negatively correlated with conductivity (r = −0.628), pH (r = −0.631), density (r = −0.552) and total sugar content (r = −0.890). Conductivity is positively correlated with free acidity (r = 0.688) and total sugar content (r = 0.776), and negatively correlated with water content (r = −0.628). All honeys were in line with Codex Alimentarius standards, except for 3 types of honey (M1, M2 and M4) for free acidity and electrical conductivity, showing possible fermentation of these honeys.

Stochastic differential equation (SDE) is an ordinary differential equation with a stochastic process that can model the unpredictable real-life behavior of any continuous systems. It is the combination of differential equations, probability theory, and stochastic processes. Stochastic differential equations arise in modeling a variety of random dynamic phenomena in physical, biological and social process. The SDE theory is traditionally used in physical science and financial mathematics. Recently, more researchers have been conducted in the application of SDE theory to various areas of engineering. This dissertation is mainly concerned with the existence of mild solutions for impulsive neutral stochastic differential equations with nonlocal conditions in Hilbert spaces. The results are obtained by using fractional powers of operator in the semigroup theory and Sadovskii fixed point theorem.

服装企业的业务流程非常繁琐，每天需要处理成百上千的库存单位，并要管理无数的款式、结构、客户标识甚至更多的数据。在这种复杂性极高的经营管理中，通过ERP系统管理来实现精确的预测、材料采购管理、生产计划和分销管理就显得尤其重要。而中国的服装企业大多属于劳动密集型企业，其自动化程度还比较低，这给服装行业的信息化的实现带来了相当大的难度。ERP也就成了很多厂家愈罢不能的软肋。

Objective: To propose approaches to improve nursing handoffs for surgical patients, including standardization. Background: Handoffs, or the transfer of accountability and patient information, can generate potential risks for patient safety. Standardization has been proposed to help improve handoffs. Methods: After observing 333 nursing handoffs in the surgical wards of our institution, we conducted a thematic content analysis, comparing and contrasting the observations. Results: Handoff processes, including the use of support tools, varied among the observations. Common themes in the handoff content suggested possibilities of standardization. About half of the 51 interruptions occurring during the observed handoffs were by healthcare professionals. Conclusions: Standardization to improve handoffs should address both the content and the process. Interruptions were common and should be avoided whenever possible. Future studies should also consider the use of mobile applications to support handoffs and clinical documentation.

In general, seeds are not used immediately after harvesting. For this reason, they have to be stored for future use, which requires the maintenance of their viability during the storage time by applying the appropriate conservation technology for each species. This study aimed to evaluate whether package and environmental conditions interfere with the physiological quality of chia seeds (Salvia hispanica L.) stored for 12 months. The experiment consisted of a completely randomized design in a 3?× 3 × 4 factorial scheme, with four replications, using three packages, three storage environments, and four storage times. After each storage time, seeds were subject to germination and vigor tests (emergence and electrical conductivity). Chia seeds can be stored in a cold or dry chamber, in plastic, glass, or paper containers, for 12 months, without hindering seeds physiological quality.
