Legumes, including lupins, beans, lentil and chickpea, are one of the most important crops in the world because of their nutritional quality. Lupin seeds have been used as human food and animal feed since ancient times. It was known that antioxidant photochemical in foods have many health benefits including prevention of various diseases associated with oxidative stress such as cancer, cardiovascular disease, neuro-degeneration and diabetes. Lupin grains are rich sources of complex carbohydrates, protein, vitamins and minerals. Antioxidants can be found naturally in foods. Total polyphenols content and antioxidant activity were measured in four varieties of lupin, namely in white lupin, blue lupin, yellow lupin and Mutabilis lupin species. A majority of antioxidants naturally present in foods occur in phenolic structures and especially in flavonoid structures. The content of the total polyphenols was determined by using the Folin-Ciocalteu reagent (FCR). Antioxidant activity was measured by using a compound DPPH (2.2-diphenyl-1-picrylhydrazyl). In the present experiment according to the average contents of total polyphenols (TPC) in dry matter of lupin seeds there was the following line: L. Angustifolius (blue) lupin (696.212 mg GAE.100g-1) > L. Albus (white) lupin (614.13 mg GAE.100g-1) > L. Luteus (yellow) lupin (467.78 mg GAE.100g-1) > L. Mutabilis (pearl) lupin (367.36 mg GAE.100g-1). Based on the measured values of total antioxidant capacity (TAC) of lupin samples can be classified as follows: L. Albus (white) lupin (43.44%) >L. Angustifolius (blue) lupin (38.27%) >L. Luteus (yellow) lupin (22.29%) >L. Mutabilis (Pearl) lupin (20.80%). The relationship of antioxidant capacity with total polyphenolic was discussed. According to used statistical analyzes. Correlation between the phenolic contents and antioxidant capacity was significantly positive (r = 0.88). Our results confirmed that legumes can be a good source of bioactive compounds in the human nutrition. The main objective of the present work was to evaluated the content of total polyphenols and an antioxidant capacity of four Lupine species. © 2017 Potravinarstvo Slovak Journal of Food Sciences, License.

This paper proposes a novel controller for automatic voltage regulator (AVR) system. The controller is a four term control type consisting of proportional, integral, derivative, and second order derivative terms (PIDD2). The four parameters of the proposed controller are optimized using particle swarm optimization (PSO) algorithm. The performance of the proposed PIDD2 is compared with various PID controllers tuned by modern heuristic optimization algorithms. In addition, a comparison with the fractional order PID (FOPID) controller tuned by Chaotic Ant Swarm (CAS) algorithm is also performed. Furthermore, a frequency response, zero-pole map, and robustness analysis of the AVR system with PIDD2 is performed. Practical implementation issues of the proposed controller are also addressed. Simulation results showed a superior response performance of the PIDD2 controller in comparison to PID and FOPID controllers. Moreover, the proposed PIDD2 can highly improve the system robustness with respect to model uncertainties. © 2014 Karabuk University

An important aspect of sustainable construction is the recycling or reuse of the construction and demolition (C&D) waste to maintain a friendly green environment. The wide range of building materials and its compositions inhibit the efficient waste management and complete recycling after demolishing. To contribute in this field and promote the use of local waste as 100% alternative coarse aggregate in construction industry, an experimental program was carried out using samples of main Iraqi building C&D waste. The types of aggregate used represent the three main constituents within recycled aggregates: unbound stone, crushed concrete, and crushed brick. Tests for mechanical properties of different types of recycled aggregate included crushing value and abrasion resistance. Using multilinear correlation analysis, the influences of these aggregate characteristics and other parameters on the properties of recycled aggregate concrete were evaluated. The results showed that the performance of the concrete containing each type of RA was largely influenced by the aggregate nature and quality, in addition to attached mortar content. © 2014 American Society of Civil Engineers.

Iraq has suffered severely from drought in recent years and the year 2008 was the driest, particularly in the Iraqi Kurdistan region. This study incorporated Geoinformation technology into mapping the drought that severely affected the Kurdistan region in the years 2007-2008. Geoinformation technology provides support in the theories, methods and techniques for building, and development of Digital Earth aspect. Five vegetation, soil, water, and land surface temperature (LST) indices were applied to two Landsat 7 ETM + imageries of June 2007 and June 2008, to assess the drought impacts in Erbil governorate Kurdistan during the study period. The indices that were employed in this study were Normalized Difference Vegetation Index, Bare Soil Index, Normalized Differential Water Index, Tasseled Cap Transformation Wetness, and LST. The results revealed a significant decrease in the vegetative cover (56.7%) and a decline in soil/vegetation wetness (29.9%) of the total study area. Likewise, there was a significant reduction in the water bodies surface area in the region such as Dokan Lake, which lost 32.5% of its surface area in comparison with the previous year, 2007. The study results showed that the soil moisture content was the most effective actor on the vegetative cover, LST, and drought status in the study area. © 2011 Taylor & Francis.

The photocatalytic transformation of the insecticide chlorpyrifos O,O-diethyl-O-(3,5,6-trichloro-2-pyridinyl) phosphorothioate have been studied in different types of natural waters such as lake, river, ground as well as in distilled and drinking water under natural sun light and simulated irradiation sources. Physico-chemical properties of the natural water were determined which were chosen as the major indicators (namely pH, electric conductivity, turbidity, Cl-, Na+, K+, NO3-, SO42 -, PO43 - and NH4+). Kinetic experiments were monitored using high performance liquid chromatography connected with UV-spectrophotometer detector. It was found that the photocatalytic degradation in all systems used in this work exhibited pseudo-first-order kinetics. The degradation rate constants were always higher for the heterogeneous catalysis in a system (TiO2/UV) compared to the systems (radiation alone, TiO2/visible or TiO2/sun). © 2010.

A model, based on the ratio number of surface atoms to that of its internal, is derived to calculate the size dependence of lattice volume of nanoscaled materials. The model is applied to Si, Sn and Au nanoparticles. For Si, that the lattice volume is increases from 20 3 for bulk to 57 3 for a 2 nm size nanocrystals. A model, for calculating melting point of nanoscaled materials, is modified by considering the effect of lattice volume. A good approach of calculating size-dependent melting point begins from the bulk state down to about 2 nm diameter nanoparticle. Both values of lattice volume and melting point obtained for nanosized materials are used to calculate lattice thermal expansion by using a formula applicable for tetrahedral semiconductors. Results for Si, change from 3.7 × 10 -6 K -1 for a bulk crystal down to a minimum value of 0.1 × 10 -6 K -1 for a 6 nm diameter nanoparticle. © 2012 Elsevier Ltd. All rights reserved.

Two novel preprocessing techniques are applied to reinforce the detection performance and the image quality in microwave imaging systems designed for brain stroke detection. The image of energy distribution is obtained by applying a delay-and-sum beamforming to the backscattered signals measured using a hemielliptical array of 16 corrugated tapered slot antenna elements surrounding the head. The beamformer forms a spatially filtered combination of time-delayed response of scattering points in the head exposed to microwave radiation over the band from 1 to 4 GHz. The proposed techniques are validated on a realistic head phantom that is fabricated to emulate the electrical properties of real human head. The results show how the proposed techniques enable the detection and localization of hemorrhagic stroke accurately. © 2002-2011 IEEE.
