This study, in a broad sense, fills in the missing parts in previous efforts at pullback stripping mode design with a dipping coal seam. Three different spoiling procedures have been developed: the normal mode, where the coal seam is flat/nearly flat; the uphill mode, where the coal seam is dipping and the dragline spoils uphill; and the downhill mode, where the coal seam is again dipping but t...

Aims of the study were to assess in an elderly population the prevalences of orthostatic hypotension at different times after standing and of nighttime reverse dipping on ambulatory blood pressure monitoring, as well as their interrelationships and relative prognostic power for incident cardiovascular events. The study population consisted of 374 patients (225 women), aged 70.2+/-8.5 years, reg...

Cultural variation has been identified in a growing number of animal species ranging from primates to cetaceans. The principal method used to establish the presence of culture in wild populations is the method of exclusion. This method is problematic, since it cannot rule out the influence of genetics and ecology in geographically distant populations. A new approach to the study of culture comp...

High novelty seeking is a complex personality attribute correlated with risk for substance abuse. There are many putative mouse models of some aspects of novelty seeking, but little is known of genetic similarities among these models. To assess the genetic coherence of "novelty seeking," we compared the performance of 14 inbred strains of mice in five tests: activity in a novel environment, nov...

Regarding the increase in needs of human societies to agricultural products, increasing water use efficiency can lead to persistent use of limited water resources. Therefore, in this study using Data Envelopment Analysis (DEA), technical, allocative, managerial and economic efficiency and also Optimal level of inputs is surveyed in order to achieve maximum Efficiency in Marvdasht city in 20...

BACKGROUND AND OBJECTIVES: Ambulatory blood pressure monitoring is recommended for several diseases in childhood; however, there are no reports about its use in the monitoring of children with dilated cardiomyopathy so far. We evaluated the pattern of ambulatory blood pressure monitoring in children with dilated cardiomyopathy and correlated it to height, weight, and body mass index. METHODS: P...

BACKGROUND Normal blood pressure (BP) follows a circadian rhythm, with dipping of BP at night. However, little has been done to show how the dipping groups vary amongst the White and Asian population at different periods of the year. This study aims to examine the pattern of nocturnal dipping between the White and Asian population, as well as to compare it to the different timings of the year, ...

BACKGROUND Chemical control method using different acaricides as spray, dipping solution or pour-on is routinely used for controlling ticks. Biological control agents are favorable due to their safety for animals and environment. Entomopathogenic fungi such as Beauveria bassiana are well known for controlling ticks. In this study, two Iranian indigenous strains of B. bassiana (B. bassiana 5197 ...

OBJECTIVES To derive a method for retrospectively estimating cumulative exposure to organophosphate (OP) pesticides among a cross section of United Kingdom sheep dippers, as part of a wider epidemiological study of neurological abnormality within this group of workers. METHODS A hygiene study of dipping sessions at 20 farms using diazinon based dips was carried out by two experienced occupati...

BACKGROUND AND OBJECTIVES Inappropriately high left ventricular mass (iLVM) is known to be related to cardiovascular prognosis. A non-dipper pattern has a greater mean left ventricular (LV) mass than the dipper pattern in hypertensive patients. However, the appropriateness of LV mass in dipper or non-dipper patterns has not been adequately investigated. The aim of this study was to define the r...
