The cooperative movement in Romania represented a solution for improving the economic and social conditions of the population, especially in rural areas. This paper tracks the evolution of this movement from the 19th ...

This paper examines the cooperative movement as a key component of the social economy. Defined by democratic control and mutual aid, cooperatives provide inclusive solutions for both economic and social challenges. B...

This paper proposes a high-frequency wireless power transfer (WPT) system. This system achieves zero-voltage switching (ZVS) and the constant current (CC) and constant voltage (CV) outputs regardless of load variations a...

La teología política de Eusebio de Cesarea, primera del cristianismo, ha merecido un lugar preponderante entre los estudios sobre el pensamiento político de la Tardoantigüedad. Sin embargo, a pesar de que la posició...

Abstract Microwave irradiations from vegetation canopy are strongly influenced by its dielectric properties and give useful information for microwave remote sensing -interpretation and applications. This paper reports on...

The condition for invariance under a translation of the coordinate system of the Verdet tensor and the Verdet constant, calculated via quantum chemical methods using gaugeless basis sets, is expressed by a vanishing sum ...

With the development of Micro-Electro-Mechanical Systems (MEMS) technology, the manufacture of energy conversion elements with metal bridge membranes is becoming more mature, which can be applied in the field of self-des...

In this study, thin films of cadmium oxide (CdO) were synthesized using the chemical thermal decomposition method. The films were deposited onto a glass substrate measuring 2.5 cm x 2.5 cm x 1 mm at a temperature of 400&...

The biological processes on mosquito could be variable in response to local climatic characteristics. The thermal effects on time and the rate larval development, immature survival and adult size in local populations of ...

The relative importance of different processes and transitions in the appearance of non-LTE populations for the fundamental levels of ozone was studied by quantifying the kinetic law of every process and transition that ...

Stemless shoulder arthroplasty has the advantage of reducing stem related complications while allowing for  anatomic restoration of proximal humerus independently from the humeral canal and diaphyseal axis and preservin...

Context. Silver is a key tracer of the weak r-process in late-type stars. However, when the assumption of local thermodynamic equilibrium is relaxed, accurate abundance determinations become even more sensitive to comple...

Abstract Background A major constraint to tuberculosis control is low case finding with under-reporting to national authorities. Evidence shows that Patent Medicine Dealers are first port of call for most people with sym...

The low-frequency vibration stimulation technology can improve the seepage of fluid in low-permeability reservoir, which is rather deeper than that of the regular geotechnical formation. Few researches on the mechanisms ...

Abstract Researchers face difficulties in studying the effects of driveline efficiency on car fuel economy via bench and road tests because of long working periods, high costs, and heavy workloads. To simplify the study ...

Abstract Solar-powered electric-vehicle (EV) charging in tropical, PV-rich regions such as Uganda faces coupled stressors from high ambient temperature and intermittent solar irradiance, which can destabilize conventiona...

Desde hace años los hospitales públicos de la Argentina, y en particular los de la Provincia de Buenos Aires, han transitado y evidenciado un constante deterioro. Este deterioro fue generado por la falta de recursos ma...

This study employs a comprehensive review of 45 studies to assess the economic value of ecosystem services from different forest types across India. To estimate timeframes, the values of ecosystem services reported in th...

Abstract Coaxial aircells are designed and fabricated to measure the electromagnetic properties of ferrite materials in the frequency range from 1 MHz to 3.6 GHz. These S-parameters are actually measured connecting the a...

Dialysate sodium (Nα) and ultrafitration (UF) profiling are two methods to reduce dialysis-induced hypotension. The aim of this study was to determine the efficacy of combining these techniques to reduce dialysisinduced...

Objetivou-se avaliar os efeitos da redução da densidade energética da dieta sobre a qualidade de ovo de codornas japonesas, mantendo a mesma relação energia metabolizável (EM):nutrientes. Foram utilizadas 400 codor...

Abstract Objective To evaluate the effect of gradually increasing orthodontic force magnitude compared with a constant force magnitude on the rate of tooth movement during maxillary canine retraction. Methods This split-...

In this work by using sol-gel auto-combustion synthesis was synthesized single-phase magnesium-substituted lithium ferrite at different pH reaction medium. The synthesized materials were investigated by X-ray and Mossbau...
