The article discusses the difficulties that faces children in Hadhramout -Yemen during the civil war. While the politicians and the other elites concentrate to fight terrorism and armed groups they ignore the needs of children, woman, and other marginalized groups.

Visual Language

Traditionally, research on human language has taken speech and written language as the only domains of investigation. However, there is now a wealth of empirical studies documenting visual aspects of language, ranging from rich studies of sign languages, which are self-contained visual language systems, to the field of gesture studies, which examines speech-associated gestures, facial expressions,

Experimental investigation on heat transfer characteristics of various nanofluids in an indoor electric heater

Heat transfer characteristics of an electric heater were experimentally investigated by using various fluids in this paper, including Cu-EGW (a mixture of ethylene glycol and DI-water), Al2O3-EGW, Fe3O4-EGW nanofluids. A 4:6 mixture of ethylene glycol and deionized water was used as the base liquid. All these nanofluids were prepared by ultrasonic treatment, and nanoparticle mass concentration of

Mental health provision in schools: priority, facilitators and barriers in 10 European countries

Background: Although schools are a key setting for the provision of mental health support for young people, little is known about the facilitators and barriers for providing such support. This study aimed to collect information from schools in 10 European countries regarding the priority given to mental health support for students, existence of a mental health‐related school policy, links with rel

Electrophoretic deposition surfaces to enhance HFE-7200 pool boiling heat transfer and critical heat flux

Modulated nanoparticle-coating surfaces were fabricated by an improved electrophoretic deposition technique in this study. Pool boiling experiments were studied for HFE-7200 on the modulated nanoparticle-coating surfaces, with a smooth surface and uniform coating surfaces as comparison. It was found that the present modulated coating surfaces can enhance the heat transfer coefficient and the criti

With a Little Help from my Friends: Gender and Intimacy in Two Friendship Research Projects

Friendship is an undertheorized but increasingly important relationship in late modernity. In this article, the authors present findings from two ongoing research projects about friendship, gender and age in contemporary Sweden. They argue that discourses about gender and friendship are highly relevant for how friendship is conceptualized both among men and women, but that culturally ingrained con

Recent Advances in the Use of Molecularly Imprinted Materials in Separation and Synthesis

Molecularly imprinted materials, prepared using self-assembly imprinting protocols using only non-covalent interactions, can be used as chromatography media in aqueous phase. The recognition properties are highly dependent on the interacting species used in the imprinting protocol. Ionic interactions, together with strong hydrogen bonding, represent useful means of obtaining recognition. With incr

The renewing of Energy Performance Certificates—Reaching comparability between decade-apart energy records

Energy Performance Certificates are currently one of the most extensive data sources about the energy performance of the EUs building stock and consequently provide support for researchers and policy makers in energy regulation. As Energy Performance Certificates are being renewed, there are new possibilities to study energy performance development over time and to evaluate the building-specific e

Over-rich combustion of CH4, C2H6, and C3H8 +air premixed flames investigated by the heat flux method and kinetic modeling

An uncommon non-monotonic behavior of the temperature dependence of adiabatic laminar burning velocity has been found in over-rich methane+air flames at equivalence ratio, ϕ = 1.4. To find out the universality and reasons of this turning point, methane, ethane and propane + air flames are studied both experimentally by the heat flux method and numerically using GRI-mech, USC-mech, UCSD-mech, FFCM

Air inlet angle influence on the air-side heat transfer and flow friction characteristics of a finned oval tube heat exchanger

In this study, the influence of various air inlet angles on the heat transfer and flow friction characteristics of a 2-row plain finned oval tube heat exchanger is analyzed by experimental and numerical methods. The experimental results show that an air inlet angle 45° provides the best heat transfer performance, and an air inlet angle 90° provides the smallest pressure drop, while an air inlet an

Hairdressers’ shoulder load when blow-drying – Studying the effect of a new blow dryer design on arm inclination angle and muscle pain

During nine months, nineteen hairdressers every second/third month switched the use between a blow dryer with traditional design and one with a new design. The new blow dryer had the possibility to change between two opposite directed air flows. Every second/third month arm inclination angle and upper trapezius muscle activity were measured a whole workday, and during blow-drying in the laboratory

Multiobjective Optimization in Sewer Network Design to Improve Wastewater Quality

Sewers that constitute the main part of wastewater systems can be used as pretreatment units of wastewater treatment plants. The authors aim to increase the treatment efficiency of sewers by optimization. A hydraulic model is written and validated. A quality calculation section is added to the model according to the Wastewater Aerobic/Anaerobic Transformations in Sewers (WATS) method, and it is ca
