Algeria imports more than half of her milk requirements. The annual bill exceeds $ 1 billion. Faced with this situation, she must now think about finding a way to reduce this dependence by replacing cow's milk, in part, with another commodity abundant in the world and cheaper. In this work we used whey powder in the preparation of pastry creams. The results showed that 80% of tasters find the CA cream (100% whey) is extremely pleasant and gave it a 9/9 rating. The comparison between different pastry creams revealed that the cream prepared with 100% whey (CA) presents the best appreciations. Similarly, it presents texture improvements, smooth and homogeneous with a clear appearance and a very pleasant smell. Among the positive points we noted that the addition of whey improves water retention and reduces syneresis. Whey creams have kept a good quality after 7 days of storage at 6ºC.

Water Holding

In recent years, plants in sandy soils have been impacted by increased climate variability due to weak water holding and temperature buffering capacities of the parent material. The projected impact spreads all over the world, including New England, USA. Many regions of the world may experience an increase in frequency and severity of drought, which can be attributed to an increased variability in precipitation and enhanced water loss due to warming. The overall benefits of biochar in environmental management have been extensively investigated. This review aims to discuss the water holding capacity of biochar from the points of view of fluid mechanics and propose several prioritized future research topics. To understand the impacts of biochar on sandy soils in-depth, sandy soil properties (surface area, pore size, water properties, and characteristics) and how biochar could improve the soil quality as well as plant growth, development, and yield are reviewed. Incorporating biochar into sandy soils could result in a net increase in the surface area, a stronger hydrophobicity at a lower temperature, and an increase in the micropores to maximize gap spaces. The capability of biochar in reducing fertilizer drainage through increasing water retention can improve crop productivity and reduce the nutrient leaching rate in agricultural practices. To advance research in biochar products and address the impacts of increasing climate variability, future research may focus on the role of biochar in enhancing soil water retention, plant water use efficiency, crop resistance to drought, and crop productivity.

Residue Incorporation

Civil construction is one of the most resource-consuming sectors in the world. For this reason, the last years have witnessed the study of reusing industrial residues in building materials. The ornamental stone processing industry has a considerable environmental liability related to residue generation during the cutting stages of granite blocks. The objective of this work is to analyze the viability of incorporating granite residues, up to 100%, to substitute sand in coating mortars for building construction. Mortars without residue, as control, and incorporated with 20, 40, 60, 80, and 100% of granite residue were subjected to consistency tests, incorporated air and water retention together with the rheological characterization using the squeeze-flow and the dropping-ball methods. The results show that mortars with 40% granite residues presented greater plastic deformation, helping their applicability by also presenting improved technological properties in the fresh state.

Algeria imports more than half of her needs for milk and cereals. Faced with this situation, she must now think of finding a way to reduce this dependence by replacing cow's milk, in part, with another commodity abundant in the world and cheaper. In this work we used whey powder in bread making. The results showed that 71.5% of tasters found that PA bread (100% whey) was extremely pleasant and gave it a score of 9/9. The breads obtained have optimal characteristics with a beautiful appearance including a good appearance, regular shape and a smooth crust. The interior is also pleasant, with a very supple crease, little elastic, non-sticky and easy tearing. These good rheological characteristics are the result of a good balance between elasticity and extensibility. The whey breads have kept a good quality (organoleptic and microbiological) after 7 days of storage at 6ºC in plastic packaging.

Severe Shortage

The world suffers from drought, which has a negative impact on human, economic, social, cultural and tourism fields. As science progressed and developed, several ways of reducing drought were found. This phenomenon is also called (aridity and infertility, and water retention), it means a severe shortage of water resources due to low precipitation and low rainfall over a specific normal period time, which are causing heavy losses in agricultural production, and the occurrence of disasters and human calamities such as starvation, and it is forcing some population to emigrate collectively. The artificial neural networks (ANN) and the Standard Rain Index (SPI) were used in the analysis of the rainfall for all Iraqi governorates for the period 1991-2016 monthly. This study shows that the best model of the neural network is [19-3-1] according to AIC to forecast the amount of rainfall, and that the Iraqi provinces over next 10 years are exposed to a different behavior of climate between moderate dry and average humidity, and increase the area of ​​desertification.

Rate Of Evaporation

The accumulation of DDT in the environment over the years is a major concern in the world today. The extent to which DDT may be absorbed and translocated from 14C-p,p¢-DDT contaminated soils into cowpea plant tissues, and the variation of uptake of p,p¢-DDT by the plants in relation to the dissipation of p,p¢-DDT in the soils was studied using a radioisotope technique. Significant absorption and accumulation of residues was observed for the cowpeas grown in two different sites, coastal and highland regions. The degree of uptake varied with soil type and growing conditions. Further results indicated that the higher the water retention by the soil the higher the rate of evaporation of p,p¢-DDT. Coastal region p,p¢-DDT soil samples showed DDE to be the major metabolite. DDT residue in the plants ranged from 0.94 to 7.73 mg/kg, while that in the soils ranged from 88.9 to 32.0 mg/kg. Preliminary electrode reactions indicated lowering of overpotential for reduction of p-chlorophenol by about 1 V, using copper phthalocyanine tetrasodium tetrasulfonate as the catalyst in microemulsion. Microemulsions and appropriate catalysts are a promising system for the decomposition of DDT.

AbstractA pragmatist philosophy of psychological science offers to the direct replication debate concrete recommendations and novel benefits that are not discussed in Zwaan et al. This philosophy guides our work as field experimentalists interested in behavioral measurement. Furthermore, all psychologists can relate to its ultimate aim set out by William James: to study mental processes that provide explanations for why people behave as they do in the world.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl & McCormack argue that animals cannot represent past situations and subsume animals’ memory-like representations within a model of the world. I suggest calling these memory-like representations as what they are without beating around the bush. I refer to them as event memories and explain how they are different from episodic memory and how they can guide action in animal cognition.

AbstractFe XIV 530.3 nm coronal emission line observations have been used for the estimation of the green solar corona rotation. A homogeneous data set, created from measurements of the world-wide coronagraphic network, has been examined with a help of correlation analysis to reveal the averaged synodic rotation period as a function of latitude and time over the epoch from 1947 to 1991.The values of the synodic rotation period obtained for this epoch for the whole range of latitudes and a latitude band ±30° are 27.52±0.12 days and 26.95±0.21 days, resp. A differential rotation of green solar corona, with local period maxima around ±60° and minimum of the rotation period at the equator, was confirmed. No clear cyclic variation of the rotation has been found for examinated epoch but some monotonic trends for some time intervals are presented.A detailed investigation of the original data and their correlation functions has shown that an existence of sufficiently reliable tracers is not evident for the whole set of examinated data. This should be taken into account in future more precise estimations of the green corona rotation period.
