Following this discussion of the inferences that can be formed from using IRR and NPV comes a description further steps should done as direct result those inferences. These additional taken since they are directly related to premises. It is strongly recommended these actions carried out conclusions have been formed. As result, it will guide decision whether or not invest in agricultural sector....

A model was developed for the economic evaluation of embryos for producing bull lines for use in commercial beef production. The fundamental concept underlying the model is that a cloned and sexed embryo of known genetic characteristics for beef traits is used to produce a bull. After reaching physiological maturity, the bull is used in natural matings. Equations relating feed energy requiremen...

OBJECTIVE This study tried to assess sensitivity, specificity, positive and negative predictive value of procalcitonin for diagnosis of neonatal bacterial infections. METHODS This prospective cross sectional study was carried out during an 18-month period in NICU and neonatal wards of Besat Hospital in Hamedan province, Iran. 39 symptomatic infants with clinical and laboratory findings in fav...

PURPOSE We aimed to evaluate ultrasonography (US) findings for Breast Imaging Reporting and Data System (BI-RADS) category 4 lesions using BI-RADS US lexicon and determine the positive and negative predictive values (PPV and NPV) of US with respect to biopsy results. METHODS Sonograms of 186 BI-RADS 4 nonpalpable breast lesions with a known diagnosis were reviewed retrospectively. The morphol...

The internal rate of return (IRR) is generally considered inferior to the net present value (NPV) as a tool for evaluating and ranking projects, despite its inherently useful comparability to the cost of capital and the return of other investment opportunities. We introduce the ‘‘selective IRR’’, a return criterion which, as a selection of an extended set of possible IRRs, is NPV-consistent. Th...

Background/introduction Symptomatic localized adenomyosis is generally treated conservatively, or with more radical treatments such as hysterectomy. An effective non-invasive therapy is needed, especially for those who wish to preserve their fertility. MR-guided Focused Ultrasound ablation (MRgFUS) has been shown as an effective treatment for symptomatic uterine leiomyomas with a large non-perf...

Replacing fossil flues by renewable and sustainable energies have been the concern of scientists working in this area over the recent decades. Furthermore, greenhouses play a key role in producing various crops year-round and in bohemian climates. For this objective, the greenhouses employ heating, ventilating and air conditioning (HVAC) systems to provide the favourable conditions for the cons...

Accessible online at: www.karger.com/journals/res Although negative pressure ventilation (nPV) is an effective therapy for patients with restrictive lung disease [1] its position in the management of chronic ventilatory failure due to chronic obstructive pulmonary disease (COPD) is less clear. In the largest study to address this question Shapiro et al. [2] randomised 184 patients to receive ei...
