We propose that the different angular distributions in two-photon collisions observed at low and high center-of-mass energies Wγγ indicate the transition from nonperturbative to perturbative QCD. We calculate the differential cross sections of γγ → ππ, KK in the angle θ of one of the final-state mesons using QCD sum rules and the perturbative QCD approach based on kT factorization theorem. Our ...

It is not unusual that researchers are active in cultures and languages other that English. Many computer assisted qualitative data analysis tools have been restricted to English, and frequently the academic supervisor may not be conversant in the language of the research domain. NVivo offers some practical and theoretical advantages to the researcher working in a language other than English, a...

ABSTRAK Kemajuan dalam bidang sains, teknologi, kejuruteraan dan matematik (STEM) memberikan sumbangan yang besar kepada ekonomi Malaysia terutama terhadap peluang pekerjaan. Walaupun ramai graduan STEM adalah wanita, penyertaan mereka pasaran buruh masih rendah. Justeru, kajian ini dijalakan untuk mengenalpasti jenis persekitaran pekerjaan diperlukan oleh wanita agar menceburi STEM. Rentetan i...

BACKGROUND Children regularly consume foods from quick-service restaurants (QSR), but little is known about the foods that children order, the calories and nutrients consumed, the accuracy of stated calorie information, or the ability to assess food orders and consumption in QSRs. This study evaluated the feasibility of plate waste collection in QSRs and examined children's orders and consumpti...

Background Risk governance involves processes and mechanisms to understand how risk decisions are taken executed. This concept has gained a reputation over time as being essential for emerging comprehensive management that defines the success of an organization. While guiding documents explain use related nuclear safety security available worldwide, few locally conducted studies have explained ...

Introduction The Scottish Medicines Consortium (SMC) conducts early health technology assessment of new medicines in Scotland. While budget impact is not a factor decisions on reimbursement, information provided initially through horizon scanning reports for high (estimated net >GBP 500,000 [EUR 585,710] per annum) to aid financial planning and implementation advice at the local level, later...

This article contains one NVivo 10® file with the complete 432 projects design documents (PDD) of seven waste management sector industries registered as Clean Development Mechanism (CDM) under United Nations Framework Convention on Climate Change (UNFCCC) Kyoto Protocol Initiative from 2004 to 2014. All data analyses and sample statistics made during the research remain in the file. We coded PD...

ABSTRACT Objective: to discuss the use of software in concept analysis through: 1) considerations made by peers who apply package their nursing practices; 2) correlation between NVivo 10® and stages using Walker & Avant method. Method: this is a theoretical-reflective essay, based on Avant, constructed after bibliographic survey discussion with methodological framework data practices. Resul...
