The purpose of this study is to conduct the financial and emission analysis of the Lahendong site as a case study of geothermal powerplant in Indonesia. The outputs of energy model in RETScreen worksheet are power capacity, electricity generation, annual GHG emission reduction, the Internal Rate Return (IRR) and payback period. The sensitivity analyses also were carried out at two scenarios (no...

High unemployment rate has encouraged the growth of various business units as job providers for productive age. This study aims to examine opportunities cow farming in Gorontalo region. It uses combination qualitative and quantitative method. The method is done by observation interview. analysis calculating cash flow, net present value (NPV), internal return (IRR), benefit cost ratio, gross mar...

BACKGROUND Meta-analysis can be used to pool rate measures across studies, but challenges arise when follow-up duration varies. Our objective was to compare different statistical approaches for pooling count data of varying follow-up times in terms of estimates of effect, precision, and clinical interpretability. METHODS We examined data from a published Cochrane Review of asthma self-managem...

Let G be a finite group and V be a finite G–module. We present upper bounds for the cardinalities of certain subsets of Irr(GV ), such as the set of those χ ∈ Irr(GV ) such that, for a fixed v ∈ V , the restriction of χ to 〈v〉 is not a multiple of the regular character of 〈v〉. These results might be useful in attacking the non–coprime k(GV )–problem.

Although infrared radiation (IRR) is ubiquitous in the terrestrial milieu, its effects on human skin have until now been largely ignored. Recent studies suggest an important role for infrared A (IRA) radiation (760-1440 nm) in dermal inflammation, photoaging, and photocarcinogenesis. In this issue, Calles et al. identify and analyze the IRA-induced transcriptome in human dermal fibroblasts. The...

Let Γ(G) be a set of all simple graphs of order n and sizem, without isolated vertices, with vertex degree sequence d1 ≥ d2 ≥ ·· · ≥ dn > 0. A graph G is regular if and only if d1 = d2 = · · ·= dn. Each mapping Irr : Γ(G) 7→ [0,+∞) with the property Irr(G) = 0 if and only if G is regular, is referred to as irregularity measure of graph. In this paper we introduce some new irregularity measures ...

STUDY DESIGN A multicenter, prospective, consecutive database of surgical patients with adult spinal deformity (ASD). OBJECTIVE This study investigated the use of antifibrinolytic (AF) therapy in ASD surgery. SUMMARY OF BACKGROUND DATA AF therapy has been shown to be effective in preventing blood loss in some settings. Its effect on major and minor perioperative complications, blood product...

IMPORTANCE The vascular risk attributable to HIV infection is rising. The heterogeneity of the samples studied is an obstacle to understanding whether HIV is a vascular risk across geographic regions. OBJECTIVE To test the hypothesis that HIV infection is a vascular risk factor, and that the risk conferred by HIV varies by geographical region. DATA SOURCES A systematic search of publication...

Background Hepatitis C virus (HCV) infection has been associated with increased non-liver-related morbidity and mortality. However, studies have yielded inconsistent results. Methods The incidence of clinical events in human immunodeficiency virus (HIV)–infected HCV-seropositive and incidence density–matched HCV-seronegative participants of the Swiss HIV Cohort Study from August 1994 to Decem...
