The sperm quality index (SQI) and sperm mobility index (SMI) both predict sperm motility. Previous research was conducted comparing the SMI with the SQI; however, semen was diluted improperly for the SQI (40-fold). For an accurate comparison, semen must be diluted 10-fold for the SQI. Therefore, the overall objective of this study, utilizing 4 experiments, was to examine the relationship of the...

The Scientific Quality Index (SQI) was proposed as a qualitative index in 2017 to evaluate the scientific outputs of researchers. In this article, in addition to introducing this index, the results of the most recent researches using this index are mentioned to provide the necessary background for related researches within the country.

Abstract Background Soil quality, which can be inferred using indicators that interact synergistically, is affected by land use types and agricultural management practices. This study assessed the status of soil quality under three adjacent uses (cultivated, grazing, fallow) in Kersa subwatershed (622 ha). samples were collected from surface (0–20 cm depth) identified with replications paramete...

BACKGROUND Within the intensive care unit (ICU), arterial blood pressure (ABP) is typically recorded at different (and sometimes uneven) sampling frequencies, and from different sensors, and is often corrupted by different artifacts and noise which are often non-Gaussian, nonlinear and nonstationary. Extracting robust parameters from such signals, and providing confidences in the estimates is t...

Article develops recommendations for the use of reducing (incentive) coefficients in land tax calculation on agricultural lands, taking into account quality and interrelation between an increase decrease soil fertility, which leads to tax. In calculating taxation, this is formed based normative value land. The inextricably linked with index (SQI), determines fertility soil. As decreasing increa...

The high demand of rice is fulfilled by intensification, particularly with the use chemical fertilizer that allegedly causes land and environmental problems in a long term. As public awareness health rises, more fields are managed organically semi-organically, but there still many manage inorganically. Assessment soil quality three types field management important to prove organic have better t...
