The wavefront recording plane （WRP）, subsequently generalized to be known as the virtual diffraction plane （VDP）, is a recent concept that has been successfully deployed in fast generation and processing of digital hologram.. In brief, the WRP and its extension, the VDP, is a hypothetical plane that is located between the hologram.and the object scene, and which is at close proxim.ty to the latter. As such, the fringe patterns on the hypothetical plane are carrying the holistic inform.tion of the hologram. as well as the local optical properties of the object scene. This im.ortant property enables a hologram.to be processed with classical im.ge processing techniques that are norm.lly unsuitable for handling holographic inform.tion. In this paper we shall review a num.er of works, that have been developed based on the fram.work of the WRP and the VDP.

The polyphagous shot hole borer （PSHB）, Euwallacea sp., was first detected in 2003 in Los Angeles County, California, USA. Recently, this invasive species has becom. a m.jor pest of m.ny hardwood trees in urban and wildland forests throughout southern California. PSHB is nearly identical in m.rphology and life history to the tea shot hole borer （TSHB）, Euwallaceafornicatus, an invasive pest of hardwoods in Florida, USA and m.ny other parts of the world. However, m.lecular studies have suggested that the taxa are different species. We conducted m.rphom.tric and chem.cal analyses of the pheno- types of Euwallacea sp. collected in southern California （Los Angeles County） and E. fornicatus collected in Florida （m.am.-Dade County）. Our analyses indicated that PSHB has 3 larval instars. The third larval instar was separated from.the first 2 instars by head capsule width with 0 probability of m.sclassification. The body length, head width, and pronotal width of PSHB adult m.les were significantly less than those of fem.les. Head width and pronotal width of fem.le PSHB were significantly less than those of fem.le TSHB. In contrast, body length, and ratio of body length to pronotal width of fem.le PSHB were significantly greater than those of fem.le TSHB. However, fem.les of these 2 species could not be separated com.letely by these 4 m.asurem.nts because of the overlapping ranges. Cuticular hydrocarbons detected in both species were exclusively alkanes （i.e., n-alkanes, m.nom.thylalkanes, dim.thylalkanes, and trim.thylalkanes）. Cuticular hydro- carbon profiles of PSHB m.les and fem.les were sim.lar, but they both differed from.that of TSHB fem.les. Cuticular hydrocarbons of PSHB were predom.nantly internally branched dim.thylalkanes with backbones of 31 and 33 carbons, whereas cuticular hydro- carbons of TSHB fem.les were dom.nated by internally branched m.nom.thylalkanes and dim.thylalkanes with backbones of 28 and 29 carbons. m.ltiple com.ounds within these classes appear

This paper focuses on the relationship between taxation and corruption in transition countries in Central and Eastern Europe. It seem. plausible that negative relationships exist between corruption and tax effort and between corruption and foreign direct investm.nts. However,research regarding corruption faces serious m.asurem.nt problem. due to the phenom.non’s very nature. A prelim.nary look at the available data provides som. weak em.irical evidence of a possible relationship between tax effort and corruption on the one hand and between foreign direct investm.nts and corruption on the other. Further research into these subjects seem. warranted.

We discussed the unsteady flow of an incom.ressible viscous fluid in a rotating parallel plate channel bounded on one side by a porous bed under the influence of a uniform.transverse m.gnetic field taking hall current into account. The perturbations are created by a constant pressure gradient along the plates in addition to the non-torsional oscillations of the upper plate. The flow in the clean fluid region is governed by Navier-Stoke’s equations while in the porous bed the equations are based on Darcy-Lapwood m.del. The exact solutions of velocity in the clean fluid and the porous m.dium.consist of steady state and transient state. The tim. required for the transient state to decay is evaluated in detail and ultim.te quasi-steady state solution has been derived analytically and also its behaviour is com.utationally discussed with reference to different flow param.ters. The shear stresses on the boundaries and the m.ss flux are also obtained analytically and their behaviour is com.utationally discussed.

Two ultra low profile inverted L antennas located on the square conducting plane are num.rically and experim.ntally analyzed as the m.ltiple input m.ltiple output (m.m.) antenna system. When the size of conducting plane is 0.45 λ by 0.45 λ and the height of antenna is 0.03 λ, the directive gain of 4.12 dBi and the return loss bandwidth of 3.67% are achieved. The proposed antenna has good diversity gain shown by the correlation coefficient, and becom.s less than 0.02 at the frequency of 2.45 GHz band when the distance between inverted L elem.nts is 0.33 λ. The results show the weak m.tual coupling of the proposed antenna and its perform.nces are prom.sing as m.m. antenna applications.

Background: Team.based care is an essential ingredient of chronic disease m.nagem.nt including chronic m.ntal illness. Effective health care team. include m.m.ers who have defined, yet intersecting roles, where m.tual respect characterises professional interaction and the patient’s well-being is central. The aim.was to explore the perception of psychologists, psychiatry registrars and psychiatrists with respect to GPs’ role in m.naging difficult-to-treat-depression (DTTD). m.thods: A previously developed sem.-structured interview schedule com.rising six questions was used. Thirty-two health professionals participated. Data were analysed using the Fram.work m.thod. Findings: Four m.in them.s em.rged: 1) The team.approach was im.ortant, particularly to ensure inform.tion accuracy and/or when responding to patient needs and pressures;2) Referrals, usually generated by GPs can be a vehicle for other health professionals to provide advice to the GP;3) Availability and accessibility often depended on health professionals work location and knowing how to navigate the system.4) Lim.ted availability of governm.nt funding im.acts on patients’ accessibility to health professionals. Discussion: Interprofessional relationships were described as param.unt. Appropriate and tim.ly referrals are integral to patient m.nagem.nt, regardless of challenges. Ongoing challenges include program.funding, workforce num.ers and costs to patients. Im.rovem.nt to m.ntal health care access was noted, even for patients am.ng relatively disadvantaged groups and those receiving m.dicare Benefits Schedule-subsidised services. Conclusion: Despite adequate GP/specialist com.unication, the delivery of optim.l team.based care to patients with difficult-to-treat depression is com.rom.sed by lack of access to specialised services and inadequate funding.

The objective of this investigation was to study the effects of nitrogen on tolerance to water-stress in cotton (Gossypium.hirsutum.L.) seedlings. Growth cham.er studies with pots of washed sand were carried out in Fayetteville, USA, and Nanjing, Chinawith three water conditions (well-watered, drought-stressed, and waterlogging), and three nitrogen rates, low nitrogen (16 m., approxim.tely 224 m. N·l–1 water), m.dium.nitrogen (24 m., approxim.tely 448 m. N·l–1 water) and high nitrogen (32 m., approxim.tely 672 m. N·l–1 water), respectively. The results showed that water-stress treatm.nts reduced plant biom.ss, C/N ratio, root vigor and leaf photosynthesis (Pn). The plant response to water-stress resistance was affected by nitrogen, and was correlated with the activities of antioxidant enzym.s. The changes of anti-oxidant enzym.s was the highest in the low nitrogen rate in the drought-stressed and waterlogged cotton seedlings. m.londialdehyde (m.A) content increased significantly in the water-stress treatm.nts, and was the lowest in the low nitrogen rate. There was a significant reduction of N accum.lation under water stress. Low-nitrogen treatm.ntincreased C accum.lation, while high-nitrogen treatm.nt decreased N accum.lation. Root vigor was decreased by water stress, and was highest in the low-nitrogen rate. After term.nating the water stress, N application prom.ted root vigor, especially in waterlogged seedlings. The trends of Pn weresim.larto that of root vigor. These results suggested that low N application m.y contribute to cotton drought tolerance by enhancing the activity of antioxidant enzym.s and conse-quently decreasing lipid peroxidation, and enhancing root vigor. However, higher N should be applied to waterlog- ging-stressed cotton seedlings after term.nating waterlogging.

Precast prestressed Hollow Core Slabs (HCS), are one of the fam.us and widely used slabs for concrete structures all over the world and widely im.lem.nted in the m.ddle East. HCS are used in industrial, com.ercial, residential buildings, as well as, in the parking structures. This paper succeeded to present new special details for deep HCS to enhance and strengthen the web shear strength capacity of HCS 400 and 500 m. depths respectively at the open parking area. This is subjected to heavy truck wheel loads so as to achieve the LRFD Code’s requirem.nts. However, it is noticed m.ny web shear cracks of HCS are used at parking area at m.ny projects in Gulf Region. On the other hand, ACI318-14 perm.ts no shear reinforcem.nt in prestressed HCS thickness of less than 12.5 in (320 m.). The paper presents experim.ntal tests program. to verify the num.rical finite elem.nt of deep HCS under m.xim.m.design uniform.loads, in addition to the new strengthening techniques. New strengthening techniques succeed to enhance the web shear capacity by significant percentage, due to the new details for HCS 400 by 68% up to 256% increasing of the web shear capacity com.ared to the ordinary HCS section. Also, HCS 500 shear capacity is enhanced with different percentages of strengthening techniques by 55%, up to 197% based on the different cases of strengthening. Furtherm.re enhancing deep HCS shear perform.nce;the new techniques have an advantage of an easy execution at the site;casting with structural topping, otherwise the preparation can be done in precast factory before site handover, which saves tim. and cost com.ared to the others traditional strengthening techniques.
