This study aimed to find out how the insulation of the footwear changes over one week of use. A thermal foot model with 8 measuring zones and 5 “sweat glands” was used for tests. A thin sock was donned on the model to allow better water distribution all over the foot surface. Four boots were tested over a period of 5 days. Each day was divided into 9 hour measurement period and 15 hour conditionin
Enzymatic pretreatment of algae by means of cellulose degrading enzyme was evaluated through lab-scale and pilot-scale experiments. The degradation efficiency of the enzyme depended on the initial physical quality of the algae. Lab-scale batch anaerobic digestion experiments showed comparatively low methane potential for the pretreated algae at both mesophilic and thermophilic temperatures. Howeve
Desertification, climate variability and food security are closely linked through drought, land cover changes, and climate and biological feedbacks. In Ghana, only few studies have documented these linkages. To establish this link the study provides historical and predicted climatic changes for two drought sensitive agro-ecological zones in Ghana and further determines how these changes have influ
In order to make the hydrogen economy fully sustainable, renewable resources have to be employed for its production. Simulation models, developed with Aspen Plus to calculate mass and energy balances, will be used to integrate the process steps necessary to produce pure hydrogen from biomass in a 2-stage fermentation process. The main challenge is the reduction of water and heat demand connected t
Syria, as well as many other countries in the Middle East, faces serious water shortage problems. Available water per capita (AWPC) will dramatically decrease due to climate change, population increase, and water needed for economic growth. Rainwater harvesting can play an important role in increasing available water in Syria. However, the absence of rainwater sewer systems in many rural areas in
The effect on a model drug delivery system when adding a drug, lidocaine, has been studied. Temperature and concentration dependence of a nonionic microemulsion with part of the oil, 1 and 10 vol. %, substituted with drug has been investigated. A nonionic oil-in-water microemulsion consisting of CH3(CH2)(11)(OCH2CH2)(5)OH, (C12E5), decane, water and the drug (lidocaine) that has been used to subst
The effect of hydrogen enrichment to natural gas flames was experimentally investigated at atmospheric pressure conditions using flame chemiluminescence imaging, planar laser-induced fluorescence of hydroxyl radicals (OH PLIF), and dynamic pressure monitoring. The experiments were performed using a third generation dry low emission (DLE) burner used in both SGT-700 and SGT-800 industrial gas turbi
Finger tapping to isochronous pacing stimuli is a well established experimental paradigm first described in the late 19th century. Two variables of common interest in rhythmic tapping tasks are timing variability and constant error. However, a difficulty when estimating these variables is that at interstimulus intervals longer than 2 seconds participants regularly overshoot the target interval and
In 1975 Mozambique attained its independence from Portugal, but it was only in 1992 with the establishment of a peace agreement after the extended civil war that the country was able to initiate its development process including the undertaking of research and development (R & D) efforts. Government and international cooperation provided the support for the R & D programmes and projects, m
Within a course in academic writing, first-term students of English currently construct individualized study-plans detailing both what they should do during the term and when they should do it. Students calculate the average workload for all their courses, and include in their study-plans all the hours they should spend both in and outside the classroom on each course, totalling in 40-hour working
Husserlian phenomenological theory is offered as an integrated and integrating for an understanding of management decision making and related issues in work and organizational sciences. The aspects of meaning, meaning constitution, subjective processes, and perspectives, mutual understanding of each other´s perspective, individuals as horizons of possible worlds are central to this conception, mak
Super-obesity, a body mass index>50 kg/m(2), is difficult to treat. Many studies have focused on the anatomic changes of the intestines; the physiologic background is not clearly identified. It is established that Roux-en-Y gastric bypass (RYGB) augments secretion of glucagon-like peptide-1 (GLP-1), peptide tyrosine tyrosine (PYY), and insulin, but other aspects of gut hormone cell function in the
This article presents the developments of an ongoing research aimed at modelling the influence of fissuring on the behaviour of clays. In particular, it recalls the main results of an extensive laboratory investigation on a fissured bentonite clay from the south of Italy and presents the data of a new investigation on the evolution with shearing of the strain fields developing within the clay, res
