Control problems

Chronic kidney disease (CKD) is increasingly recognized as a major health problem worldwide. Objectives: (1) To evaluate the malondialdehyde concentration and kynurenine and tryptophan ratio for differences between CKD patients and healthy controls. (2) To analyze the relationship and correlation between these biomarker indexes and some risk factors of CKD.

Drug resistant tuberculosis (DR-TB) remains a global health problem. The diagnosis, treatment, and management of DR-TB are the major challenges to Vietnam National Tuberculosis Control Program. One of the most important solutions for overcoming this problem is developing reliable and low-cost methods, which have been proposed to Drug Susceptibility Testing (DST) to detect drug resistant tuberculosis.

Stabilizing the depth of the Towed Underwater Vehicle (TUV) under the impact of ocean waves is the first problem when building a control and monitoring system for TUV. Many strategies and control methods have been proposed in different studies, but they are not a general standard.

Planning involves selecting a course of action and specifying how the action will be implemented. The first step in planning is to identify the various alternatives. Next, the alternative that does the best job of furthering the organization’s objectives is selected. Management’s plans are usually expressed in budgets. Typically, budgets are prepared annually under the direction of the controller, who is the manager of the accounting department.

The aim of this study is to explore and develop methods of controlling colour while overcoming many of the inherent problems in the processing. Because to the enormous variety of paper available, testing for printing was narrowed to primarily 100% cotton papers. The negative was critical in realising the full potential of the salt prints tonal range. The film tested was limited by availability in the Australian market. The research into various films to create digital output negatives proved to be complex and time consuming.

The second essay examines the effect of banking system reform, which is defined by the presence of foreign banks, on investment-cash flow relation in a context of a small transition economy. I find evidence that the presence of foreign banks in Vietnam results in decreasing in firm’s dependence on local banks and has changed their financial constraint. Company investments are less reliant on internal cash flow in the post reform period.

The earth’s surface is two-thirds water, yet most of this is undrinkable or unusable because it is either seawater or ice. Of the 1% that is available as fresh water, most is used for farming or industry. Fresh water pollution is the major problem because many rivers and streams are being polluted with pesticides, industrial waste, and sewage. In poor and developing countries, the addition of sewage to the sources of water leads to diseases, and even death. A United Nations’ report estimates that more than 78% of people drink from polluted water supplies.

THE EFFECTS OF CUSTOMER LOYALITY ON PROFITABILLITY Chapter Three turns to a wholly different, but not unrelated, topic, the role of admissions exam scores in the identification of well-prepared students in the college admissions process. The case for using such exams is often made with “validity” studies, which estimate the correlation between test scores and eventual collegiate grades, both with and without controls for high school grade point average. I argue that there are two fundamental problems with these studies as they are often carried out.

In this paper we present the solution to a longstanding problem of differential geometry: Lie’s third theorem for Lie algebroids. We show that the integrability problem is controlled by two computable obstructions. As applications we derive, explain and improve the known integrability results, we establish integrability by local Lie groupoids, we clarify the smoothness of the Poisson sigma-model for Poisson manifolds, and we describe other geometrical applications.

In Vietnam rodents are one of the three most important problems identified by the agricultural sector. The damage caused by rodents in agricultural systems is an important impediment to rural development in the Mekong Delta region. This proposal capitalises on the research findings and on the measurement of farmers' belief and practises associated with rodent control in the Mekong Delta.
