The sex ratio, gonadosomatic index, stages of gonadal development and fecundity of sompat grunt Pomadasys jubelini off Lagos coast, Nigeria were investigated. P. jubelini had sex ratio of 1: 0.85 (male to female). The difference in sex ratio was not significantly different (p > 0.05) from the expected 1:1 distribution. Gonadosomatic index ranged from 0.07 to 7.29% with mean of 2.25 ± 0.08%. Hig...

Based on the statistical data from 1997 to 2017, with utilization of IPCC carbon accounting method, Tapio decoupling model, and Logarithmic Mean Divisia Index (LMDI), temporal evolution characteristics Qinghai’s energy-related emissions, relationship, its driving factors were analyzed. The results indicated that 1) emissions Qinghai showed a trend first slowly increasing, then rapidly finally f...

the convergence hypothesis maintains that an economy whose productivity lags behind other economies has a potential to grow faster. in other words, this economy can experience faster economic growth through absorbing, accepting, and using available technology experience. in this study, we have examined the relationship between tfp of industry sectors and regional convergence in iran's prov...

BACKGROUND AND PURPOSE Isolated systolic hypertension (ISH), systolic blood pressure (BP) > or =160 mm Hg and diastolic BP (DBP) <90 mm Hg, is associated with stroke; however, the correlation between specific BP indices and stroke mortality in ISH is not defined. METHODS In a pooled analysis of 9 epidemiological studies, we examined whether pulse pressure (PP) was more predictive of stroke mo...

China faces a difficult choice of maintaining socioeconomic development and carbon emissions mitigation. Analyzing the decoupling relationship between economic its driving factors from regional perspective is key for Chinese government to achieve 2030 emission reduction target. This study adopted logarithmic mean Divisia index (LMDI) method Tapio index, decomposed forces decoupling, measured se...

We consider a spectrum-sharing cognitive radio system with antenna selection applied at the secondary transmitter (ST). Based on the extreme value theory, we deduce a simple and accurate expression for the asymptotic distribution of the signal to interference plus noise ratio at the secondary receiver. Using this result, the asymptotic mean capacity and the outage capacity for the secondary use...
