iran is one of the countries facing the most severe farmland fragmentation (ff) in rural areas and farmland consolidation (fc) is generally regarded as being a suitable instrument to solve this problem . a case study in the central area of iran was conducted to explore landholder's attitudes towards issues related to ff and fc. randomized stratified sampling frame was used to select 146 landhol...

background: human sperm cryopreservation has proven to be very valuable. cryopreservation has effects on function, morphology and percentage of fertilization capacity of human sperm. also, it has been revealed that cryopreservation has a role in sperm dna fragmentation and infertility. in this study, viability, motility, dna fragmentation and for the first time, intracellular nitric oxide asses...

Abstract We consider the inverse problem of determining fragmentation rate from noisy measurements in growth-fragmentation equation. use Fourier transform theory on locally compact groups to treat this for general probabilities. develop a regularization method based spectral filtering, which allows us deal with weighted <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" ...

in order to analyse the effective factors contributing to land fragmentation, required data ‎were collected by questionnaire from 151 farmers who were selected through a stratified random ‎sampling design from 12 villages of ramjerd yek subdistrict of marvdasht country. factor analysis ‎was used to identity explanatory factors of land fragmentation. the variables of natural-farming, ‎socio-cult...

The aim of this report has been evaluating protamine content and DNA integrity of two patients with globozoospermia undergoing Intra Cytoplasmic Sperm Injection (ICSI). Semen analysis was carried out according to WHO criteria. Protamine deficiency and DNA fragmentation was assessed using Chromomycin A3 and sperm chromatin dispersion assay respectively. ICSI and chemical activation were carried ...

Taking into account the quasi-continuous fragmentation of meteor particles, the formulae describing the variation of both light and ionization along the atmospheric trajectory of meteoroids, are derived. Two methods of data processing are presented enabling the determination of the parameters of quasicontinuous fragmentation,R0, andR1, characterizing the parent body and the fragmentation produc...

The longitudinal, transverse and asymmetric components of the fragmentation function are measured from the inclusive hadrons produced in e + e ? collisions at LEP. As in the deep inelastic scattering, this provides important tests of QCD predictions. Using the lifetime tag procedure it is possible to select Z 0 ! bb events and to compare the fragmentation functions in bb and light quarks events...

Data fragmentation has been proposed as a solution for protecting the confidentiality of sensitive associations when publishing data at external servers. To enrich the utility of the published fragments, a recent approach has put forward the idea of complementing them with loose associations, a sanitized form of the sensitive associations broken by fragmentation. The original proposal considers...
