Investigating gas resource potentiality from Late Jurassic Madbi Formation in the NW –Say’Un-Masila Basin,Eastern Yemen

Late Jurassic Madbi shale samples from Al-Qarn-01 well in the NW Say’un-Masila Basin, Eastern Yemen are analyzed using conventional geochemical data such as total organic carbon (TOC) content and Rock-Eval pyrolysis. The results in this study are used to evaluate the gas resource potentiality in the basin. The analyzed shales have high TOC content between 1.00% and 3.12%, and their HIs range from 77 to 177?mg HC/g TOC. These values indicate that the investigated Madbi shale intervals contain Type III kerogen and are considered to be very good gas-source rocks. Furthermore, the relatively high Rock-Eval pyrolysis T_max (447–459?°C) and PI (0.09–0.44) values indicate mainly peak to late mature oil window.     

Effect of Different Drying Procedures on the Nutritional Value of the Mantle and Tentacles of <Emphasis Type="Italic">Sepia officinalis</Emphasis>

The aim of this work was to investigate the influence of two different drying methods, traditionally by sun and controlled temperatures of 45, 50, 60 and 70 °C and relative humidity of 20 and 30% on the chemical composition of Sepia officinalis. When compared to fresh samples, lipid content increased under both drying methods whereas protein levels significantly increased only under controlled conditions. Drying procedures increased the percentage of saturated fatty acids mainly in sun‐dried samples and at high temperature (70 °C). A significant decrease in the amount of polyunsaturated fatty acids was detected in sun‐dried samples. No significant differences were found between the levels of polyunsaturated fatty acids of fresh cuttlefish and those under controlled conditions. The highest value of malondialdehyde in mantles was observed in sun‐dried samples, while in tentacles the highest level was seen at 70 °C. The highest level of advanced oxidation protein products was noted in traditionally sun‐dried samples. The results obtained showed that 45–50 °C and 20–30% humidity conserved the value of proteins and lipids more than traditional drying. Results of this study may be suitable for developing a reliable industrial index.     

A study of users' acceptance and satisfaction of emergency call service

In recent years, there has been rapid and significant development of road transport technologies in order to reduce the number of killed and injured people on roads. These include safety technologies, emergency call systems (eCall), and advanced traveler information systems. The eCall system is an automatic in‐vehicle emergency call service, which is mainly used for notifying emergency services about dangerous road situations and their exact location. In this paper, an eCall platform prototype is developed to allow quick and efficient rescue of injured people in dangerous road situations. The eCall function is developed and installed in nomadic devices (e.g., smartphones and tablets). Large‐scale field operational tests were conducted in real settings to assess the impacts of the eCall function provided by in‐vehicle nomadic devices. More precisely, experiments were conducted by more than 250 participants with different sociodemographic profiles in order to study the users' acceptance of the use of the developed eCall function for large‐scale usage. The collected data are analyzed, and results are reported. Performed experiments showed the usefulness, acceptance, and satisfactory performance of the eCall service.

Scheduling two identical parallel machines with preparation constraints

In this paper, we consider the problem of scheduling a set of n jobs on two identical machines with preparation constraints. Each job requires before its execution a set of resources and a non-negligible preparation time. The objective is to minimise the makespan. This problem is NP-hard. We prove the NP-hardness of two specific cases where in the first case preparation times take only three values, whereas in the second case preparation times and the release dates take only two values, respectively. Then, we present some special cases and heuristic algorithms along with an experimental study.     

Application of ethnic food composition data for understanding the diet and nutrition of South Asians in the UK

Lack of food composition data, recipe information and portion sizes for ethnic foods are commonly reported problems for dietary assessment of ethnic minority groups. One of the main aims of this study was to use food composition data to validate portion sizes, identify important sources of nutrients and describe the characteristics of the South Asian diet. The top five ethnic foods containing highest levels of selected nutrients were lamb balti (3 mg/100 g iron), lamb kebab (3.2 mg/100 g zinc), mixed dhal (62 μg/100 g folate), fish curry (1.4 μg/100 g vitamin D), ghee (968 μg/100 g retinol) and toor dhal (9.1 g/100 g dietary fibre). Typical adult South Asian diets included traditional cereals (chapatti, rice and paratha) and low consumption of meat dishes; with vegetable curries contributing most towards energy intake. A higher consumption of full fat milk and fruit juices by toddlers and school children were observed when compared with the National Diet and Nutrition Survey of the UK.     

Normal Mode Method for Two-Temperature Generalized Thermoelasticity Under Thermal Shock Problem

The theory of two-temperature generalized thermoelasticity, based on Youssef's theory, was used to solve boundary value problems of one-dimensional generalized thermoelasticity half-space by heating its boundary with different types of heating. The governing equations are solved using new mathematical methods within the purview of the Lord-?hulman (L-S) theory and the classical dynamical coupled theory (CD). The general solution obtained is applied to a specific problem of a half-space subjected to one type of heating—thermal shock type. The separation of variables method is used to get the exact expressions for distributions of displacement, the stresses, and temperature distribution. Variations of the considered functions through the horizontal distance are illustrated graphically. Comparisons are made with results between the two theories. Numerical work is also performed for a suitable material and results are discussed, specifically the conductive temperature, the dynamical temperature, and the stress and strain distributions are shown graphically when discussed.     

Metal Chelates with Some Cellulose Derivatives. II. Preparation and Characterization of Co(II)-CMC Complexes

Complexes of three grades of sodium carboxymethyl cellulose (CMC) with cobalt(II) chloride have been prepared and characterized by elemental analysis, magnetic measurements, and infrared (IR) and electronic spectroscopy. The studies revealed that CMCs react with cobalt(II) in the stoichiometric ratio 1:1 (metal ion:ligand). The ligand field parameters of the octahedral Co(II) complexes were calculated. The stability of these complexes was studied in DMF medium using spectrophotometric methods. The optimum conditions favoring complex formation are critically evaluated.     

Use of lipoprotein lipase in the improvement of some properties of wool fabrics

Wool fabrics were pretreated with hydrogen peroxide in the presence of different stabilisers; namely, sodium silicate, magnesium sulphate and imino disuccinic acid sodium salt. The effect of stabiliser type and concentration on the properties of the treated wool were studied. Imino disuccinic acid sodium salt was found to be the most effective stabiliser for hydrogen peroxide when added to the bleaching bath of wool fabric. The effect of after‐treatment of the pre‐oxidised wool fabric with commercially produced lipoprotein lipase enzyme on its dyeability with acid and reactive dyes, as well as on some of its physico‐mechanical properties, was assessed. Chemical and microscopic analyses were conducted to assess changes in the chemical composition of wool treated with this system. Wool fabrics treated with hydrogen peroxide/imino disuccinic acid sodium salt/lipoprotein lipase enzyme exhibit improved wettability and, hence, dyeability with both acid and reactive dyes, as well as enhanced resistance to felting shrinkage and pilling, without severe deterioration in the fabric’s inherent properties.     

Hydrocarbon potentiality, burial history and thermal evolution for some source rocks in October oil field, northern Gulf of Suez, Egypt

This paper attempts to apply a one dimensional model on four source rocks (Belayim, Lower Rudeis, Thebes, and Brown Limestone formations), in East Warda concession, October oil field, throughout the different geological times. Moreover, the fundamental aspects of the petroleum system in the study area is evaluated through studying maturation and hydrocarbon potential in order to gain an understanding of onset of oil generation and expulsion. The position of three wells (syn. or pseudo wells) is proposed based on the available geological and thermal data. Also, the existing temperature database is enhanced by using the available temperature data for 220 wells in the Gulf of Suez and the Red Sea, 53 wells in the Mediterranean Sea, 29 wells in the Nile delta, 7 wells in Sinai, 2 wells in Upper Egypt and 39 wells in the Western desert. Finally, the timing of oil generation for Belayim, Thebes, Lower Rudeis and Brown Limestone source rocks in the Northern Gulf of Suez area is updated. From this study we conclude that, the cumulative yield of the Belayim and Lower Rudeis formations is lower than that of the Thebes and Brown Limestone formations.
