Salinity stress im.acts crop growth as well as production. The need for increased food production to feed the increasing population and the lim.ted resources, i.e. optim.l quality land and water, require developing strategies to m.tigate m.rginal stresses, including salinity stress, for reasonable expectation of crop production. A pot experim.nt was conducted in a greenhouse at the National Research Centre, Dokki, Cairo, Egypt in the sum.er season of 2005 to evaluate the effects of foliar application of ascorbic acid alone or in com.ination with zinc sulfate on the growth and photosynthetic pigm.nts of m.llet plants irrigated by tap water (250 ppm. 0.39 dS·m.1) or m.derate to high salinity irrigation water [2500 ppm.(3.9 dS·m.1) and 5000 ppm.(7.8 dS·m.1)]. Increased salinity in the irrigation water decreased the plant growth, biom.ss, and carotenoid content. Foliar application of ascorbic acid alone increased num.er of leaves and leaf area, while in com.ination with zinc sulfate increased the plant height and total plant biom.ss. However, these treatm.nts had no significant effects on the photosynthetic pigm.nts. This study dem.nstrates that exogenous application of ascorbic acid can enhance foliar growth which m.y contribute to increased plant biom.ss and yield.

Irrigation with high salinity water influences plant growth, production of photosynthetic pigm.nts and total phenols, leading to reduction in crop yield and quality. The objective of this study was to investigate the effects of potassium.(K) foliar application in m.tigating the negative effects of salt stress on pepper plants. A greenhouse experim.nt was conducted to investigate the effects of foliar application of potassium.(K) on pepper plants grown with different salinity water irrigation (3000 and 6000 ppm.as com.ared to tap water with salinity level of 300 ppm.. Irrigation using high salinity water decreased plant height, biom.ss production, and fruit yield as com.ared to those of the plants irrigated by tap water. Photosynthetic pigm.nts and total phenols increased in the form.r as com.ared to those of the latter plants. The m.st serious affect was for the plants under highest salinity irrigation (6000 ppm. as com.ared to that of the plants under m.derate salinity irrigation (3000 ppm.. Foliar application of potassium.m.no phosphate (Km.) at 200ppm.concentration increased the plant growth, biom.ss production, and fruit yield. Chlorophyll_a content and total phenols increased significantly with foliar application of 100 ppm.Km.. Further increase in foliar Km. concentration to 200 ppm.had no significant benefits on photosynthetic pigm.nts and total phenols content. This study dem.nstrated that foliar application of Km., to som. extent, m.tigated the negative effects of high salinity water irrigation on pepper plant growth and fruit yield.

In the era of big data, huge volum.s of data are generated from.online social networks, sensor networks, m.bile devices, and organizations’ enterprise system.. This phenom.non provides organizations with unprecedented opportunities to tap into big data to m.ne valuable business intelligence. However, traditional business analytics m.thods m.y not be able to cope with the flood of big data. The m.in contribution of this paper is the illustration of the developm.nt of a novel big data stream.analytics fram.work nam.d BDSASA that leverages a probabilistic language m.del to analyze the consum.r sentim.nts em.edded in hundreds of m.llions of online consum.r reviews. In particular, an inference m.del is em.edded into the classical language m.deling fram.work to enhance the prediction of consum.r sentim.nts. The practical im.lication of our research work is that organizations can apply our big data stream.analytics fram.work to analyze consum.rs’ product preferences, and hence develop m.re effective m.rketing and production strategies.

We explore the use of Granular Activated Carbon (GAC) as a m.tigation technique for the treatm.nt of drinking water that was artificially enriched with Rn-222 in laboratory by placing a radium.rich granite stone (pitchblende) in a closed container filled with tap water for several days in order to allow Rn-222 concentration to approach its highest possible level. Granular Activated Carbon (GAC) was im.ersed into the water container in order to adsorb Rn-222 in radon-rich water. The optim.m.activation procedure for GAC preparation was determ.ned. Suitable contact tim. and optim.m.quantities of GAC needed to reduce Rn-222 concentration in water were experim.ntally determ.ned. There is a m.ch greater increase in Rn-222 rem.val from.water in the ranges from.1 part: 1000 parts to 4 parts: 1000 parts GAC/water ratios. Further increase in GAC/water ratio slowly affects the Rn-222 rem.val.

A greenhouse experim.nt was conducted to test and com.are the suitability of saline com.ost and saline irrigation water for nutrient status am.ndm.nt of a slightly productive sandy clay loam.soil, to study the m.cronutrient utilization and dry m.tter production of wheat （Triticum.aestivum.c.v. Gem.iza 7） grown in a m.dified soil environm.nt and to determ.ne the effects of com.ost and saline irrigation water on soil productivity. The sandy clay loam.soil was treated with com.ost of five rates （0, 24, 36, 48, and 60 m. ha-1, equivalent to 0, 3, 4.5, and 6 g kg-1 soil, respectively） and irrigation water of four salinity levels （0.50 （tap water）, 4.9, 6.3, and 8.7 dS m.l）. The results indicated that at harvest, the electrical conductivity （EC） of the soil was significantly （P 〈 0.05） changed by the com.ost application as com.ared to the control. In general, the soil salinity significantly increased with increasing application rates of com.ost. Soluble salts, K, C1, HCO3, Na, Ca, and m., were significantly increased by the com.ost treatm.nt. Soil sodium.adsorption ratio （SAR） was significantly affected by the salinity levels of the irrigation water, and showed a slight response to the com.ost application. The soil organic carbon content was also significantly （P 〈 0.05） affected by application of com.ost, with a m.xim.m.value of 31.03 g kg-1 recorded at the com.ost rate of 60 m. ha-1 and the irrigation water salinity level of 8.7 dS m.1 and a m.nim.m.value of 12.05 g kg-1 observed in the control. The com.ost application produced rem.rkable increases in wheat shoot dry m.tter production. The m.xim.m.dry m.tter production （75.11 g pot-1） occurred with 60 m. ha-1 com.ost and norm.l irrigation water, with a m.nim.m.of 19.83 g pot-1 with no addition of com.ost and irrigation water at a salinity level of 8.70 dS m.1. Significant increases in wheat shoot contents of K, N, P, Na, and C1 were observed with addition of com.ost. The relatively high shoot N values m.y be attributed

The pursuit of alternative safe water has increased dram.tically the world trade in bottled water. Events happened in Canada which changed the population’s perception about the quality of tap water, despite all governm.nt efforts. m.dia has an im.ortant role to pass on inform.tion because there is value judgm.nt in its reports. As a result, this study aim. to present recent data from.two Canadian newspapers of national circulation, which refer to tap water and bottled water. It used quantitative and qualitative data for this analysis. The study concludes that the m.dia, taken into consideration, provides its readers with im.ortant inform.tion, but the inform.tion can also be am.iguous. Nevertheless, it arouses interest in further research about this subject m.tter and about protecting water resources.

This paper was conducted to m.nitor the effect of m.xed essential oils (AROm.X@) as phytogenic extract herbs adm.nistration in drinking water on growth perform.nce, hem.tological, biochem.cal, im.unological statuses and carcass traits of broiler chickens. A total num.er of 240 unsexed broiler chicks (Cobb-500) strain, were random.y divided to four equal groups, 60 chicks each at seven days of age. The first group drank tap water (control), the second, third and fourth group were drank the sam. water, adding 1 m. AROm.X@per 5, 10 and 15 liter tap water, respectively for 5 week of age. It was cleared from.the results that there was a significant im.rove in feed conversion ratio, red and white blood cell counts, total protein, album.n, globulin, calcium. inorganic phosphorus and a relative reduction in the liver enzym.s but in the norm.l range. However, it was observed that m.x essential oils have no significant im.act on carcass organs. High levels of the vital param.ters, low levels of hepatic enzym.s showed that birds health was good and relative im.rovem.nt in im.une system. The relative im.rovem.nt of the absorption of m.nerals such as calcium.and inorganic phosphorus to the positive role of essential oils. Adm.nistration in drank water was occasion, a regular activity of hepatic enzym.s which can evidence safety and hepato-protective nature of these oils. Therefore, it is cleared from.the results that the addition of these extract herbs in drinking water enhances the health m.at, perform.nce and physiological status of broiler chicks, which helps to obtain healthy m.at and suitable for hum.n consum.tion.
