introduction: pulmonary tuberculosis is major problem worldwide and it is estimated one third the world population are already infected and each year 9 million people develop full blown tuberculosis of these 3 million die of the disease, annually. delay in diagnosis and treatment are major problems that play a significant role in all aspect of the disease from patient treatment to transmission ...

OBJECTIVE To determine short-term outcome and its predictors in patients with psychogenic nonepileptic attacks (PNEA). METHODS Retrospective cohort study of outcomes relating to attendance at follow-up, spells, use of emergency services, employment, and social security payments recorded at 6 and 12 months post diagnosis in 260 consecutive patients. RESULTS A total of 187 patients (71.9%) at...

Programs to enhance nontimber services increasingly focus on nonindustrial private forest (NIPF) owners. These owners are believed to possess multiple objectives, causing them to respond to economic forces and policies in complex and unpredictable ways. We examine NIPF owners in western Oregon and western Washington, using a survey to document their forest ownership objectives and willingness t...

Inventory models play a leading role in analyzing a lot of realistic situations arising at places like, food and vegetable markets, market yards, oil exploration industries, etc. In the present article, we developed an inventory model for deteriorating items with permissible delay in payment under inflation. In the given model, demand rate is considered as stock-dependent and deterioration rate...

Usually it is assumed that all items in a lot are of good quality, but in reality this assumption may not always be pertinent. Thus, the inspection of lots becomes essential in almost all organizations. Moreover, its role becomes more vital when the items are deteriorating in nature. Owing to this fact, this paper investigates the impact of initial inspection on retailer’s pricing and ordering ...

A continuous production control inventory model for deteriorating items with variable demand rate is developed. Demand rate is the linear function of time. In this paper we have done all work in the environment of permissible delay of payments. A number of structural properties of the inventory system are studied analytically. We have discussed the minimum total system cost under the condition ...

 This study presents an inventory model for deteriorating items with linearly time-dependent demand rate under trade credits. Mathematical models have been derived under four different situations i.e. Case 1 : The cycle time T is greater than or equal to M1, to get a cash discount, Case 2 : The cycle time T is less than M1, Case 3 : The cycle time is greater than or equal to M2, and Case 4 : T...
