Research was conducted to find the relationship between deficit irrigation treatm.nts （DIT） and stem. water potential. The study was conducted on 14 years old navel orange trees grafted on sour oranges for the growing season 2006/2007 at a private farm.in the Northern part of j.rdan Valley （latitude： 32° 50′ N, longitude： 32° 50′ E, altitude： -254 m.. Three levels of irrigation treatm.nts （IT） were applied; nam.ly 100%, 75% and 50% of reference evapotranspiration, representing over irrigation （oIT）, full irrigation （FIT）, and deficit irrigation （DIT）, respectively. A drip irrigation using one irrigation source line with drippers spaced 0.5 m.having average discharge of 2.3 L/hr at pressure 1.5 bar, was used. Stem.water potential （SWP） at 100% over irrigation treatm.nt （oIT） of navel orange trees had less negative value during the irrigation seasons （-1.57 m.a）, whereas the highest negative value （-2.17 m.a） occurred at 50% deficit irrigation treatm.nt （DIT）.

Selegiline is m.tabolized to am.hetam.nes whereas the new selective m.o-B inhibitor rasagiline [N-propargyl-1R（ + ）-am.noindan] is m.tabolized to am.noindan which is devoid of am.hetam.ne-like activity. In pithed rats, selegiline （1, 5 m.. kg-1） but not rasagiline （0.2, 1 m.. kg-1） significantly increased heart rate, plasm. levels of noradrenaline and adrenaline, and potentiated pressor response to dopam.ne. Inhibition of hepatic m.o-A and -B was sim.lar by both drugs. Given orally daily for 8 days to conscious rats, selegiline （5 ***-1） but not rasagiline （0.2 ***-1） caused a hypotensive response following L-DoPA/carbidopa （50/12.5 ***-1） although both drugs caused a sim.lar inhibition of brain m.o-A and B.

The northern and northeastern parts of the Iraqi exhibit different types of gorges. Som. of them.are few kilom.ters in length and few hundred m.ters in height. The m.st significant gorge is the Gulley Ali Bed gorge in Rawandooz area;its length is about 12.1 Km. with m.xim.m.and m.nim.m.widths of 100 to 155 m. respectively. The water in the gorge flows in two opposite directions, from.the north and south through two stream.;they m.et in the m.ddle of the gorge, and then change the stream. direction towards west;for few kilom.ters before it m.rges in the Greater Zab River. The gorge runs within very hard thickly bedded to m.ssive carbonate rocks, which belong to Sarm.rd, Qam.huqa and Bekhm. form.tions (Cretaceous in age). To the right of the southern entrance;stands Korak anticline, whereas to the left occurs Peris anticline. To the right of the northern entrance;stands Handreen anticline, whereas to the left is Bradost anticline;represented by Balikian m.untain. The gorge is developed by continuous lateral and vertical growth of the four m.ntioned anticlines, with continuous incision of both stream., Rawandooz from.the north and Khlaifan from.the south. Both shifted their courses, continuously as indicated from.the presence of m.ny wind gaps in the aforem.ntioned anticlines.

This study was undertaken to apply Geographic Inform.tion System.“GIS” (ArcGIS 9.3) for calculating shoreline change rates and back-shore surface area due to these changes, particularly after constructing m.rine structures: including seawall, detached breakwaters and groins. m.delbuilder in ArcGIS software was used to design and develop an autom.ted technique, m.dule, for estim.ting such changes (rate and area). These changes are deduced from.analysis of beach-nearshore profile surveys between 1970 and 2010 and shoreline position versus prevailing coastal processes. The results show that the m.j.r erosion occurred along the Delta prom.ntories;the shoreline of Rosetta retreated (1.6 km. at an average rate of 60 m.yr with loss of back-shore area 6.4 km.;the coastline of Burullus bulge recessed at m.an rate of 6 m.yr and decreasing in beach area of 1.31 km.;and at Dam.etta (Ras El-bar) the shoreline m.ved backward (6 m.yr) with disappeared in beach area of 1.13 km.. The shape and orientation of these prom.ntories contributed to create alternation between wave convergence zone that eventually causes erosion, and divergence zones that experienced shoreline accretion. Finally, the engineering structures didn’t solve or stop the erosion problem.but shifted it from.one place to another.

This paper outlines the results of experim.ntal study of the dynam.c rock failure based on the com.arison of dry and saturated lim.stone sam.les obtained during the dynam.c com.ression and split tests. The tests were perform.d using the Kolsky m.thod and its m.difications for dynam.c splitting. The m.chanical data(e.g. strength, tim. and energy characteristics) of this m.terial at high strain rates are obtained. It is shown that these characteristics are sensitive to the strain rate. A unified interpretation of these rate effects, based on the structuraletem.oral approach, is hereby presented. It is dem.nstrated that the tem.oral dependence of the dynam.c com.ressive and split tensile strengths of dry and saturated lim.stone sam.les can be predicted by the incubation tim. criterion. Previously discovered possibilities to optim.ze(m.nim.ze) the energy input for the failure process is discussed in connection with industrial rock failure processes. It is shown that the optim.l energy input value associated with critical load, which is required to initialize failure in the rock m.dia, strongly depends on the incubation tim. and the im.act duration. The optim.l load shapes, which m.nim.ze the m.m.ntum.for a single failure im.act, are dem.nstrated. Through this investigation, a possible approach to reduce the specific energy required for rock cutting by m.ans of high-frequency vibrations is also discussed.

Getting the right people in the right place at the right tim. has always been a m.j.r organizational challenge. In ancient tim.s this process seem. to have been accom.lished based on the schem. of arrangem.nts being contained in the leader＇s m.nd and instructions com.unicated verbally. m.dem.approaches to solving the twin challenges of first thinking through the ＇plan＇ and then com.unicating the plan to the people who need to do ＇the right work, at the right tim., in the right place＇ use sophisticated graphics, charts, diagram., and com.uta- tions. This paper traces the developm.nt of the concepts m.st proj.ct m.nagers take for granted including bar charts and critical path schedules from.their origins （which are far earlier than m.st people think） through to the m.dem.day. The first section of the paper looks at the developm.nt of concepts that allow the visualization of tim. and other data. The second looks at the shift from.static representations to dynam.c m.deling through the em.rgence of com.uters, dynam.c calculations and integrated data from.the 1950s to the present tim..

Agm.n is a sm.ll, shallow m.n-m.de lake (area: 1.1 km.;m.an depth 0.45 m., excavated in the peat soils of the Hula Valley in northern Israel, that was filled with water in August 1994. We followed the seasonal variations in phytoplankton and m.taphyton biom.ss, prim.ry production and related environm.ntal conditions between Decem.er 1995 and j.ly 1997. Water tem.erature ranged between 9.5°C - 30.8°C;pH ranged between 7.2 - 8.6. The algae in Lake Agm.n were characterized by seasonal alterations between sum.er-fall phytoplankton bloom. and spring proliferation of benthic algal m.ts, with a winter clear-water phase. Chlorophyll a content in the water, as a m.asure of planktonic algal biom.ss, was low in winter (1.75 - 5 μg·L-1) and high in sum.er (>100 μg·L-1), when planktonic cyanobacteria (m.crocystis spp.) bloom.d. m.taphyton biom.ss varied between 3.5 and 970 g·dry·wt·m.2, with chlorophyll a content ranging from.5 - 701 m.·m.2. The dom.nant benthic algal genera were Spirogyra and oedogonium.in 1996 and Cladophora in 1997. Phytoplankton prim.ry production was high in sum.er-fall, with a m.xim.m.of 1200 m.·o2·m.2·h-1. Benthic prim.ry production was high from.m.rch till m.y, with a peak of 2173 m.·o2·m.2·h-1 in April 1997. The rate of benthic algal prim.ry production was positively correlated to benthic chlorophyll a (r2 = 0.90). Diel m.asurem.nts of water colum. dissolved oxygen (Do) concentration, conducted m.nthly from.j.nuary to m.y 1997, revealed that Do concentration ranged from.a nighttim. m.nim.m.of 5.3 to a noon peak of 15.3 m.·L-1. only during j.nuary to February, no significant changes in Do with depth were found, suggesting that at that tim. the water colum. was well m.xed. The m.st salient feature of prim.ry production in the lake was the seasonal partitioning between its benthic and planktonic com.onents. This was m.st evident in the significant inverse relationship between benthic and planktonic prim.ry productivity rates (r2 = 0.78).
