AIMS Diastolic reserve is the ability of left ventricular filling pressures to remain normal with exercise. Impaired diastolic reserve may be an early sign of diabetic cardiomyopathy. We aimed to determine whether diastolic reserve differs in type 2 diabetes (DM) compared with non-DM, and to identify clinical, anthropological, metabolic and resting echocardiographic correlates of impaired diast...

Airlines operate in an uncertain environment for many reasons, for example due to the effects of weather, traffic or crew unavailability (due to delay or sickness). This work focuses on airline reserve crew scheduling under crew absence and journey time uncertainty for an airline operating a single hub and spoke network. Reserve crew can be used to cover absent crew or delayed connecting crew. ...

percutaneous coronary angioplasty (ptca) of a coronary stenosis without documented ischemia at noninvasive stress testing is often performed, but its benefit is unproven. coronary pressure– derived fractional flow reserve (ffr) is an invasive index of stenosis severity defined as the ratio of maximal blood pressure in a stenotic vessel to the normal maximal pressure in the same vessel. ffr is a...

background: this study was undertaken to evaluate the role of day 3 fsh/lh ratio and day 3 lh level as predictors of ivf cycle outcomes. methods: this prospective observational study was undertaken in the ivf and reproductive biology centre and lok nayak hospital, affiliated to maulana azad medical college, in new delhi, india. the study included 105 women who underwent controlled ovarian hyper...

background: careful evaluation of patients and proper treatment with right techniques are essential for successful outcome of assisted reproduction. to obtain satisfactory results, it is necessary to assess ovarian reserve before planning treatment. objective: to evaluate anti-mullerian hormone as a predictor of fertility potential in terms of ovarian reserve and ovarian response reflected by a...

due to uncertain nature of wind and photovoltaic power units, the participation of this units in electricity markets is subjected to significant deviation penalties. this issue leads to despondency or even admission of these units in the competitive environment. with regard to this fact that the low deviations are available when predictions are performed in a short-term horizon and also distrib...

This research memorandum summarizes the analyses conducted for the Active/Reserve Force Mix Study. The availability of personnel to man missions being transferred to the Reserve forces is studied. In particular, this paper examines which homeports will be most able to support the Naval Reserve Force, what determines whether Navy veterans will affiliate with the Selected Reserves, and what the s...

Two features common to many auctions are the use of reserve prices and the existence of secondary markets for the goods being sold. Even in simple symmetric settings, the combination of these features can preclude existence of an equilibrium in symmetric separating bidding strategies. With a reserve price sufficiently far below the maximum (endogenous) valuation, a symmetric equilibrium still e...

In this paper the dependence of wealth distribution and the velocity of money on the required reserve ratio is examined based on a random transfer model of money and computer simulations. A fractional reserve banking system is introduced to the model where money creation can be achieved by bank loans and the monetary aggregate is determined by the monetary base and the required reserve ratio. I...

Eighteen red duikers, Cephalophus natalensis, from the Charters Creek Nature Reserve and 2 from Fanies Island Nature Reserve were processed for arthropod parasite recovery. They harboured 8 species of ixodid ticks and 2 lice species. All were infested with Haemaphysalis parmata and the nymphs of Rhipicephalus muehlensi. Two bushpigs, Potamochoerus porcus, from the Ndumu Nature Reserve, 5 from t...
