ABSTRACT Verticillium wilt in eggplants is a root disease of difficult control. In this study, we report the relationship between soil water availability and the disease intensity in order to identify management strategies that are unfavourable to the pathogen and capable of reducing the disease progression and the damage caused by it. Four irrigation management strategies were compared in soil infested or not infested with Verticillium dahliae, which consisted of: irrigating when the available soil moisture was maintained at 90% (WA90%), 55% (WA55%) and 20% (WA20%) during the entire growing cycle, and kept at 20% in the vegetative stage, and at 90% in the production stage (WA20-90%). Experimental design was in randomized blocks, including eight treatments in factorial arrangement (4x2) and three replicates. The management strategy WA20-90% led to a significant reduction in the disease severity and in the extent of xylem colonization by the pathogen. The dry mass of plants in infested soil was 12% lower than that of control treatments and was higher with the irrigation strategy WA90% than with WA55% or WA20%. The strategy WA20-90% was efficient in reducing the disease with no significant reduction in dry mass.

The Relationship

The research aims to study the relationship between the management strategies of the small projects of the workers in their dimensions: (Project phase strategy, making decisions, the project management strategy of financial production, Marketing Productive Management Strategy, the strategy of managing productive legal projects) with satisfaction with life dimensions: (Psychological compatibility, Self-compliance, Work environment, and Social compatibility) . The research sample consisted of 102 persons working in four small projects, "Ceramics - Bamboo - Serma - Hand Carpets". They were selected in a pesky-purpose manner from the employees of these projects in Sakiet Abu Shaara village, Sentris, Menoufia Governorate and 10th of Ramadan City. "General data form", "Project Management Strategies scale", and "measure of satisfaction with life" were applied. The study followed the descriptive and analytical approach. The data were categorized and analyzed using appropriate statistical methods through the SPSS statistical program such as number and percentages, arithmetic mean, standard deviation, T-test, Pearson correlation coefficient, Chi-square and F-test. The most important results are related to the relationship between the project management strategy and the financial productivity and self-compliance at the level of significance of 0.01, which means that the realization of the requirements of the project in terms of finance and meet the needs, resulting in self-compatibility.  There is also a correlation between the project management strategy and the business environment at the level of 0.01 meaning that whenever the project needs to be met in terms of funding and meet the needs of the project as this leads to compatibility with the place of residence of the project and the surrounding environment, there is an inverse correlation Between the social situation and the decision-making at the level of significance of 0.01, which means that the greater the number of employees are married the less ability to make the decisions needed in those small projects, which means the impact of the ability to make decisions on the social situation of the individual. There were statistically significant differences between the averages of the different projects in terms of the overall project management strategy according to the dwelling. The highest value was for the medium in the ceramics project and the lowest in the hand carpets where the ceramic represents the highest average 2.000 while the carpets represent the lowest average by 1.809 at the level of significance 0.1. There were significant differences between the mean of the various projects in terms of satisfaction with total life according to the dimension of psychological compatibility and the highest value for the average in the hand carpet project where the results showed that the average and standard deviation of hand carpets is (23.745 ± 4.38) The recommendations of the government, decision-makers and ministries to establish a culture of entrepreneurship and motivate young people to set up private projects through the media, paying attention to the enactment of laws on small projects to motivate young people to establish and develop small and micro enterprises, In various stages to ensure the success and continuity of the project.

The economical benefits of different irrigation strategies were assessed by long term simulation (20 years) for dry beans in Paraná, Brazil. The model BEANGRO was used to simulate crop yield and irrigation requirements assuming eight levels of irrigation threshold (20 to 90% of the remaining soil available water in steps of 10%), in addition to a level considering no irrigation. Net return was the objective function to select the optimum irrigation management strategy, assuming fixed and stochastic distributions of historical product price. The results showed that yield was significantly increased by irrigation despite a high variability for all the simulation strategies, due to variations on growth conditions over the years. Although the net return was highly variable, it was positive in 75% of the years for all strategies with threshold values higher than 30%. The strategy of irrigating the crop before the soil reaches 60% AW provided the maximum economical benefits. The high profit using this improved strategy justifies the practice of irrigation for beans in Paraná.

ABSTRACT The increase in disputes over water use in the Brazilian Cerrado has demanded improvements in irrigation management and increase in water use productivity. In this context, deficit irrigation is an interesting management strategy, as it enables water savings without significant losses of yield. The present study aimed to evaluate the phenology and yield of a soybean cultivar subjected to different soil moisture contents. The experimental design used was randomized blocks with five treatments and four replicates. In each treatment, an irrigation strategy was applied based on the available water in the soil (AW). The T1 treatment was performed by applying from 80 to 100% AW; in T2 treatment, the allowed variation was from 60 to 80% AW; in T3 treatment, it was from 40 to 60% AW; in T4, from 20 to 40% AW; and in T5, from 0 to 20% AW. It was verified that, in winter and summer, even without the need to reduce water withdrawal, it is recommended to apply from 60 to 80% of the available water in the soil for soybean crop, without decreasing yield. In situations of water restriction, it is possible to have yield of around 55 and 70% in winter and summer, respectively, for the condition from 20 to 40% of the available water in the soil.

The Black Sea, surrounded by six riparian countries, is under the threat of severe pollution, giving rise to the need of taking precautions to protect it from further deterioration. In this paper, an effort putting forth a wastewater treatment and management strategy is outlined for the Black Sea coast of Turkey, including both the technical and financial aspects. The present situation of the coast in terms of land-based pollution and infrastructure is stated, followed by an applicable management strategy. The strategy developed for the coastal settlements involves various stagewise treatment schemes based on population distribution and densities along the coastline, and on the availability of land in a specified period of thirty years. Similar strategies are proposed for the control of pollution originating from industries, for those carried by rivers joining the sea, and for leachate of solid waste landfills. The cost estimations of various treatment schemes are also given in terms of population equivalents.

Stress And Health

The aim of this article is to examine how increased worker control-on the individual as well as on the collective level-may be a means to reduce the risk of work environment-related stress and diseases. Control is also an important element in socialization processes and in work reform activities directed to a democratization of working life. The concept of control connects a number of research perspectives. It deals with the individual and the collective level, as well as the relationship between them, and it may be a bridge between a social psychological and a psychobiological perspective. In this article, the author considers the control concept primarily from a stress perspective, but also examines how production techniques, legislation, and management strategies create the structure of control at work.

AbstractNearly one-quarter of bowel obstructions occur in the large bowel. As with all bowel obstructions, large bowel obstructions have three defining characteristics: partial or complete, intrinsic or extrinsic, benign or malignant. The work-up for a large bowel obstruction should focus on the etiology of the obstruction as well as severity. Management strategy is contingent on the previous characteristics and can include endoscopy, diversion, or resection. This chapter will discuss common and rare etiologies of large bowel obstructions as well as management strategies for clinical guidance.
