The morphology, morphogenesis and infraciliature of two marine euplotid ciliates, Euplotes dammamensis n. sp. and Euplotes balteatus (Dujardin, 1841) Kahl, 1932, isolated from a sandy beach of the Arabian Gulf, Saudi Arabia, were investigated using observations in vivo and protargol-impregnation methods. Euplotes dammamensis n. sp. is characterized by a combination of features including its huge body size (100–170 × 80–120 μm), 10 conspicuous dorsal ridges, 10 normal-sized frontoventral and two marginal cirri, and 11 dorsal kineties. Euplotes balteatus is mainly characterized by 10 frontoventral, two caudal, and two left marginal cirri, 7–10 dorsal kineties and 5–7 prominent dorsal ridges as well as double-eurystomus silverline system. The small subunit rRNA (SSU-rRNA) gene sequences were determined for both species and phylogenetic analyses based on these data indicated that E. dammamensis is most closely related to E. parabalteatus Jiang et al., 2010, and E. balteatus clusters with E. plicatum Valbonesi et al., 1997, E. orientalis Jiang et al., 2010, and E. bisulcatus Kahl, 1932.

Opis:
The transition from emergency to existing exposure situation is an important stage in the nuclear or radiological emergency plan. It requires arrangements to be put in place and to be implemented so as to ensure that the transition is made in a coordinated and orderly manner of guidelines for adjusting the undertaken protective actions and other response actions. The delivering radiation doses to public and environmental pollution are monitoring that measurements should be implemented according to certain plan of intervention and protective actions in the different stages of the N/R accident. In this study, a computer model (RASCAL) is used to calculate the effect of severe accident could have detected on an operating nuclear power reactor PWR and the possible impact on the public. Features for the decision to implement the transition from emergency to existing exposure situation are proposed depending on the estimation of the collection of deliver exposure doses to the public and environment due to monitoring the different radiation sources resulting from the N/R accident.

Opis:
The profitability of a cement plant depends largely on the efficient operation of the blending stage, therefore, there is a need to control the process at the blending stage in order to maintain the chemical composition of the raw mix near or at the desired value with minimum variance despite variation in the raw material composition. In this work, neuro-fuzzy model is developed for a dynamic behaviour of the system to predict the total carbonate content in the raw mix at different clay feed rates. The data used for parameter estimation and model validation was obtained from one of the cement plants in Nigeria. The data was pre-processed to remove outliers and filtered using smoothening technique in order to reveal its dynamic nature. Autoregressive exogenous (ARX) model was developed for comparison purpose. ARX model gave high root mean square error (RMSE) of 5.408 and 4.0199 for training and validation respectively. Poor fit resulting from ARX model is an indication of nonlinear nature of the process. However, both visual and statistical analyses on neuro-fuzzy (ANFIS) model gave a far better result. RMSE of training and validation are 0.28167 and 0.7436 respectively, and the sum of square error (SSE) and R-square are 39.6692 and 0.9969 respectively. All these are an indication of good performance of ANFIS model. This model can be used for control design of the process.

Opis:
Drought is an insidious hazard of nature in many parts of the world. It originates from persistent shortage of precipitation over a specific region for a specific period of time and has a conceptual and operational definition. Drought impact on some activity, group, or environmental sector depends on the extent of water shortage and ground conditions. Algeria and especially the western region has experienced several periods of drought over the last century, since 1975 to the present day. The most recent drought in 1981, 1989, 1990, 1992, 1994 and 1999 was characterized by its intensity and spatial extent. Drought is identified using various drought indices (meteorological, hydrological and agricultural). In this research, we focus on the meteorological drought, to assess the reliability of these indices under changing climatic conditions. Data was recorded for the period of 1980–2009 at wadi Louza catchment (NW-Algeria). For describing and monitoring drought severity periods, we calculated the correlation between both meteorological drought indices: Standardised Precipitation Index (SPI) and Effective Drought Index (EDI). The results show that the watershed of wadi Louza has experienced a severe meteorological drought. The correlation between meteorological drought indices was good for all time steps and the best was found for 9-month time step. The obtained results may provide some scientific support for fighting against droughts.
Susza jest naturalnym zagrożeniem w wielu częściach świata. Powstaje wskutek trwałego ograniczenia ilości opadów w danym regionie i okresie czasu. Jest zdefiniowana w sensie konceptualnym i operacyjnym. Wpływ suszy na różne rodzaje działalności człowieka i na środowisko zależy od rozmiaru deficytu wody i od warunków glebowych. Algieria, szczególnie jej zachodnia część doświadczyła okresów intensywnej suszy już w ubiegłym wieku, począwszy od roku 1975 r., i doświadcza ich po dzień dzisiejszy. Ostatnia susza charakteryzowała się dużą intensywnością i przestrzennym zasięgiem. Suszę identyfikuje się, używając różnych wskaźników meteorologicznych, hydrologicznych lub rolniczych. W badaniach prezentowanych w niniejszej pracy skupiono się na suszy meteorologicznej, aby ocenić wiarygodność tych wskaźników w zmieniających się warunkach klimatycznych. Dane notowano w okresie 1980–2009 w zlewni uedu Louza w północno-zachodniej Algierii. Na potrzeby charakterystyki i monitoringu okresów suszy obliczono korelację między dwoma wskaźnikami – wskaźnikiem standaryzowanego opadu (SPI) i efektywnym wskaźnikiem suszy (EDI). Wyniki dowodzą, że w zlewni uedu Louza wystąpiła głęboka susza meteorologiczna. Korelacja między wskaźnikami suszy meteorologicznej była dobra w odniesieniu do wszystkich kroków czasowych, ale najlepsza w odniesieniu do okresów 9-miesięcznych. Uzyskane wyniki mogą stanowić naukowe wsparcie w walce z suszą.

Opis:
Many substances of plant origin, e.g. alkyloresorcinols, benzoxazinoids, essential oils, isothiocyanates or saponins, have been tested as potential antimicrobial agents to control various pathogenic microorganisms. Medemia agrun is a mysterious, not well-known species of the fan palm from the Nubian Desert Oases of Southern Egypt and Northern Sudan. Nuts of M. argun have been found to be rich (about 5%) in proanthocyanidins, consisting of afzelechin, catechin and gallocatechin as the main subunits of these polyphenolic compounds. The aim of this work was to assess effects of the proanthocyanidin (PAC) fraction obtained from M. agrun nuts on the in vitro growth and activity of two soil-borne fungal pathogens of cereals (Gaeumannomyces graminis var. tritici and Cephalosporium gramineum) and a beneficial soil bacterium, Azotobacter chroococcum, known to fix atmospheric nitrogen. The fungi were grown on PDA medium and A. chroococcum was cultured on Burk’s N-free medium supplemented with different concentrations of the PAC fraction. This fraction applied at the highest concentration tested (200 μg cm-3) did not affect the mycelial growth of the fungus Cephalosporium gramineum on PDA medium but significantly reduced (by 20%) that of Gaeumannomyces graminis var. tritici. Proliferation and N2-fixation by Azotobacter chroococcum in N-free liquid medium containing 500 μg cm-3 of the PAC fraction were more intensive than those in the medium with an equivalent concentration of glucose. It has been shown for the first time that this bacterium can use the PAC fraction as the only source of C and energy for N2-fixation.

Opis:
Free volume size V_{f} and proton conductivity σ of a novel polymer electrolyte membrane were investigated as a function of temperature and relative humidity up to 140°C and 80%, respectively. The free volume size V_{f} for Nafion® HP JP reflect the α-transition temperature at about 98°C. In addition the free volume size V_{f} for Nafion® HP JP is smaller than that for Nafion® NRE212 membrane which leads to lower methanol permeability of the former membrane. The proton conductivity σ for Nafion® HP JP decreases with increase of temperature up to transition temperature due to free and bound water loss, then it starts to increase due to dynamic segmental motion. It increases for Nafion® HP JP with the increase of the relative humidity. A good correlation between V_{f} and σ was successfully established for both membranes which indicates that σ is governed by the free volume. In conclusion, Nafion® HP JP is a suitable membrane for a proton exchange membrane fuel cell application.

Opis:
The present work aims at investigating the effect of microwave local positions (i.e. before crushing (BC), after crushing (AC) and after milling (AM)) on microwave-assisted flotation of chalcopyrite and pyrite in a porphyry copper complex deposit. Individual given samples for each state were pre-treated with a variable power microwave at a power level of 90 to 900W for 15, 30, and 60s. Furthermore, froth floatation experiments were carried out using a laboratory mechanical Denver flotation cell on both microwave-treated and untreated samples. Particle surface properties were characterized by a scanning electron microscopy (SEM) and an energy-dispersive X-ray spectroscopy (EDX) analysis. The results showed that the chalcopyrite and pyrite floatabilities increased monotonically by rising the exposure time and power level for the uncrushed preconditioned samples (BC) due to the enhancement of mineral liberation degrees together with the formation of sulphide species and polysulphides on the mineral surfaces. However, flotation results of treated samples for the crushed one (AC) revealed an optimum range. Formation of intensive oxide layers on the mineral surfaces of milled samples (AM) led to a substantial reduction in their recoveries by increasing the microwave’s power level and the sample’s exposure time. The results obtained from mineral’s floatabilities in recleaner stage showed that the microwave-assisted sample at 900W for 30s at BC state favourably provided 5% higher S.E.’s than that of the untreated sample. Finally, it was concluded that the microwave pretreatment of samples induced the best floatability responses if it located before the crusher.

This paper aims at examining the role of job autonomy in organizations and its relation with employee performance. This will be achieved by providing a critical review of the subject matter in existing management literature. In recent years, the concept of job autonomy has gained an increasing importance in practice of Human Resource Management. Even some studies claimed that job autonomy directly affects job performance and some of its indicators including job satisfaction, motivation, job engagement and job commitment. As a result, current paper aims at studying the effect of job autonomy on employee performance by critically reviewing existing work of human resource scholars. Main research questions approached by authors include: Is there any meaningful relationship between job autonomy and employee’s job performance distinguished in existing literature? If yes, what impact can be expected from job autonomy on employee’s job performance?

The construction phase of oil and gas projects (OGPs) is a risky process and project managers face numerous challenges during this particular period. A proper risk analysis and management during the construction phase of the OGPs not only will affect the timely and successful operation of the project as a whole, it can also affect occurrence of risks in subsequent phases and overall economic viability of the project. As a result, via using extensive literature review, this study tries to answer the question of what are main risks involved in construction phase of OGPs and which methods are used for identifying them? The outcome of this research would likely be a valuable source for construction professionals to improve project performance while managing existing risks. It is also useful to avoid common problems that befall many project managers and will assist them to have a better understanding of risk management as part of a project plan.

Opis:
The drought ranked first in terms the natural hazard characteristics and impacts followed by tropical cyclones, regional floods, earthquakes, and volcanoes. Drought monitoring is an important aspect of drought risk management and the assessment of drought is usually done through using various drought indices. The western region in Algeria is the most affected by the drought since the middle of the 70s.The current research focuses on the analysis and comparison of four meteorological drought indices (standardized precipitation index – SPI, percent of normal index – PN, decile index – DI, and rainfall anomaly index – RAI) in the Tafna basin for different time scales (annual, seasonal, and monthly) during 1979–2011. The results showed that the SPI and DI have similar frequencies for dry and wet categories. The RAI and PN were able to detect more drought categories. Meanwhile, all indices have strong positive correlations between each other, especially with Spearman correlation tests (0.99; 1.0), the meteorological drought indices almost showed consistent and similar results in the study area. It was determined in 1982 as the driest year and 2008 as the wettest year in the period of the study. The analysis of the trend was based on the test of Mann–Kendall (MK), a positive trend of the indices were detected on a monthly scale, this increasing of indices trend represent the increasing of the wet categories which explains the increasing trend of the rainfall in the last 2000s. These results overview of the understanding of drought trends in the region is crucial for making strategies and assist in decision making for water resources management and reducing vulnerability to drought.

Purpose: In supply chains, creating a secure space for data production, sending, storing, and analysis has always been a critical issue. The main goal of this research was to evaluate the importance of various security criteria in an intelligent supply chain system. Methodology: The main data collection method was the expert survey. Experts validated the security criteria and sub-criteria. Then, the importance of these criteria was evaluated using the fuzzy analytic hierarchy process method. Findings: The results revealed that reliability and privacy with their sub-criteria were the most important ones among the obtained security criteria for IoT-based supply chain management. Practical implications: The research results can provide valuable insight for supply chains’ decision-makers. The findings can also be a good reference point for researchers who work on the IoT-based supply chain concept in other countries and sectors. Research limitations: Limitations of this study are the purposive sampling method and the limited scope of studied companies and sectors. Therefore, the article provides initial insight on the matter. Originality: The study presents the research problem from a new perspective and gives possible solutions for IoT-based supply chain management.

Opis:
Squirrel cage induction motors suffer from numerous faults, for example cracks in the rotor bars. This paper aims to present a novel algorithm based on Least Squares Support Vector Machine (LS-SVM) for detection partial rupture rotor bar of the squirrel cage asynchronous machine. The stator current spectral analysis based on FFT method is applied in order to extract the fault frequencies related to rotor bar partial rupture. Afterward the LS-SVM approach is established as monitoring system to detect the degree of rupture rotor bar. The training and testing data sets used are derived from the spectral analysis of one stator phase current, containing information about characteristic harmonics related to the partial rupture rotor bar. Satisfactory and more accurate results are obtained by applying LS-SVM to fault diagnosis of rotor bar.
