Abstract

Gas Processing Facility (GPF) project achieved Zero flaring
1.7million standard cubic feet per day (41.65 tons) gas recovered thru Vapor Recovery System and protect the environment by reducing;

Vapor Recovery Unit (VRU):
Under this unit, gases from the Tertiary Ethyl Glycol (TEG)Dehydration package and vents from compressors dry gas seals are recovered/captured and compressed in the VRU and then sent to the suction for the main gas compressor for reuse instead of going to flare
Gas Processing Project (GPF) at Zakum complex is a new gas treatment platform that will augment the existing gas processing capacity of the Zakum West Super Complex. It will increase the associated gas production from Zakum oilfield. The beauty of this project is that ADMA has employed the Zero flaring policy. There will be no flaring at all at this platform. This is one of the unique project of its nature in the ADNOC group of companies, even in Emirates and could be in the whole middle east where is there would be NO flaring. We have designed flare as well in this project but that would be used only for emergencies.
GPF is a stand alone platform with independent utilities and support facilities. The GPF platform is 67.5 meter in length and 43 meters in width. GPF is located at Zakum oilfield, offshore facility about 65 kilometer Northwest of Abu Dhabi. This platform has three main decks, cellar, mezzanine and main. The flare structure consists of a 120 meter long flare bridge with a 80m above sea level angled boom. The distance from the flare tip to the GPF platform is150 m.
There will not be any flaring during normal operation of the GPF, as Zero flaring technology is installed. Hydrocarbon from the GPF platform will be recovered using a Vapour Recovery Unit (VRU) facility. Flaring will only be undertaken during emergency conditions.
How We Attain and Sustain Work-life Balance?
Authors: Burton Sharon 
Published: April 2012

Abstract
When we consider the issue of work-life balance everyone questioned will have a different opinion dependant on but not limited to: their work ethics, money, family, culture and job role. In other words what you consider a good work-life balance will not be the same as someone else. So from a corporate point of view how does a company make sure it's employees are getting that balance?
Work-life balance affects the productivity and creativity of employees. Employers that support this balance show lower numbers leaving their organisation, employees who have greater pride in their company, a willingness to recommend it as a place to work and higher overall job satisfaction. As well as benefit packages Employers offer a variety of different incentives to their employees: unsociable hours pay; compensation leave for time away from home; overtime pay; gyms at work and some companies also provide crèches. So work and home begin to blend, in fact with modern technology we never truly disconnect from work, the flashing light on a Blackberry is hypnotic and begs to be looked at. At what point is it acceptable to turn it off? An evening out? At the weekend? On holiday?
To strike the right balance Employers can offer a range of different programs and initiatives, such as flexible working arrangements and telecommuting work. More proactive employers can provide compulsory leave periods, strict maximum hours and foster an environment that encourages employees not to continue working after hours. Studies show that the solution to balance lies in four components: work, home, community and self. This paper will look at the latest research into work-life balance, to attempt to discern what both employer and employee can do to achieve it and maintain it.
Saudi Aramco's Ambient Air Quality and Source Emission Milestone: Achieving Zero Hydrocarbon Discharge in On Shore Oil Operations

Published: April 2012

Abstract
Saudi Aramco is committed to environment protection and minimizing its environmental footprint. The company environmental protection policy states: "The Company will sure that its operations do not create undue risks to the environment or public health, and will conduct its operations with full concern for the protection of the land, air and water from harmful pollution. The Company will promote environmentally sound waste disposal practices and cost effective waste minimization through source reduction, reuse, and recycling". Saudi Aramco introduced ambient air quality monitoring to Saudi Aramco since the early 1970's. This process was automated and improved as the technology advanced in that field. Many advanced technologies are used to measure or control the level of air pollutants emitted to the atmosphere from Saudi Aramco's industrial facilities. This paper explains the efforts towards eliminating any footprint on air quality by achieving zero hydrocarbon discharge during necessary flow back operations. It describes the evaluation of several alternatives while utilizing phase separators, sand filters, cyclones, surge tanks, high-pressure and low-pressure pumps/compressors to come up with a feasible, reliable and safe discharge system.

Published: March 2012

Summary

Background and objectives
Peritoneal dialysis is still used for AKI in developing countries despite concerns about its limitations. The objective of this study was to explore the role of high-volume peritoneal dialysis in AKI patients in relation to metabolic and fluid control, outcome, and risk factors associated with death.

Design, setting, participants, & measurements
A prospective study was performed on 204 AKI patients who were assigned to high-volume peritoneal dialysis (prescribed Kt/V=0.60/session) by flexible catheter and cycler; 150 patients (80.2%) were included in the final analysis.

Results
Mean age was 63.8±15.8 years, 70% of patients were in the intensive care unit, and sepsis was the main etiology of AKI (54.7%). BUN and creatinine levels stabilized after four sessions at around 50 and 4 mg/dl, respectively. Fluid removal and nitrogen balance increased progressively and stabilized around 1200 ml and −1 g/d after four sessions, respectively. Weekly delivered Kt/V was 3.5±0.68. Regarding AKI outcome, 23% of patients presented renal function recovery, 6.6% of patients remained on dialysis after 30 days, and 57.3% of patients died. Age and sepsis were identified as risk factors for death. In urine output, increase of 1 g in nitrogen balance and increase of 500 ml in ultrafiltration after three sessions were identified as protective factors.

Conclusions
High-volume peritoneal dialysis is effective for a selected AKI patient group, allowing adequate metabolic and fluid control. Age, sepsis, and urine output as well as nitrogen balance and ultrafiltration after three high-volume peritoneal dialysis sessions were associated significantly with death.

Published: March 2012

Summary

Background and objectives
BK virus is an infection in kidney transplantation patients jeopardizing graft survival. Unfortunately, there is no consensus on treatment of BK viremia and nephropathy. Leflunomide has been studied for the treatment of BK viremia and nephropathy, but there are limited data on the utility of leflunomide therapeutic drug monitoring. This study aimed to determine if a pharmacodynamic relationship exists between BK viral load reduction and leflunomide metabolite, A77 1726, serum concentrations.

Design, setting, participants, & measurements
This study was a retrospective, single-center, longitudinal analysis of patients identified with BK viremia with or without nephropathy. Patients were grouped according to whether they received leflunomide. All BK viral PCR and A77 1726 concentrations were analyzed to determine pharmacodynamics, and were correlated with clinical outcomes.

Results
Of 76 patients identified, 52 received leflunomide therapy and 24 did not. Patients who received leflunomide were further analyzed according to A77 1726 concentrations and BK clearance; there was no difference in BK clearance. There was a lack of correlation between A77 1726 concentrations and log change in BK viral PCR concentration. Multivariate analysis demonstrated that mycophenolate mofetil discontinuation, BK viremia without nephropathy, and mean BK viral load were significantly associated with BK viral clearance; leflunomide use lacked this association.

Conclusions
Pharmacodynamic analysis revealed no association between A77 1726 concentrations and BK viral PCR reductions. Multivariate analysis demonstrated that leflunomide therapy was not associated with BK viral clearance. Randomized studies are needed to determine the utility of leflunomide for BK viremia and nephropathy.

0
r
2, we show how to obtain the energy eigenvalues of the Morse potential without any approximation for any n and ℓ quantum states by using numerical calculations. The calculations have been performed for different energy eigenvalues and different numerical values of ρ

Hard-thermal-loop QCD trace anomaly
Authors: Su Nan 
Published: March 2012

Abstract
In this proceedings I summarize results of QCD trace anomaly from recent three-loop hard-thermal-loop perturbation theory (HTLpt) calculations. I focus on the trace anomaly scaled by T
2 for pure-glue and N
f = 3 QCD. The comparison to available lattice data suggests that for pure-glue QCD agreement between HTLpt results and lattice data for the trace anomaly begins at temperatures above 8 T
c while when including quarks (N
f = 3) agreement begins already at temperatures above 2 T
c. The results in both cases indicate that at very high temperatures the T
2-scaled trace anomaly increases with temperature in accordance with the predictions of HTLpt.

Published: April 2012

Abstract
The goal of this paper was to explain variability of phytoplankton in a shallow coastal area in relation to physico-chemical parameters. Temporal variability and composition of phytoplankton were investigated in the Kotor Bay, a small bay located in the south-eastern part of the Adriatic Sea. Samplings were performed weekly from February 2008 to January 2009 at one station in the inner part of the Kotor Bay, at five depths (0 m, 2 m, 5 m, 10 m, 15 m). Phosphates, nitrites and nitrates ranged from values under the level of detection to the maximum values of 1.54, 1.53 and 23.91 µmol l−1, respectively. The phytoplankton biomass — represented by chlorophyll a concentration — ranged from 0.12 to 6.78 mg m−3, reaching a maximum in summer. Diatoms were present throughout the whole sampling period, reaching the highest abundance in March (3.42×105 cells l−1at surface). The peak of dinoflagellates in July (2.2×106 cells l−1 at surface) was due to a single species, Prorocentrum micans. The toxic dinoflagellate Dinophysis fortii occurred at a concentration of 2140 cells l−1 in May. The present results of phytoplankton assemblages and distribution provide valuable information for this part of the south-eastern Adriatic Sea where data is currently absent.
Suggestions From the Field for Return to Sports Participation Following Anterior Cruciate Ligament Reconstruction: Basketball
Authors: Waters Eric 
Published: March 2012

Synopsis The purpose of this paper is to outline the final, functional phases of rehabilitation that address exercises, drills, and return-to-play criteria for the sport of basketball, following anterior cruciate ligament (ACL) reconstruction. ACL injuries can be debilitating and affect the quality of life for recreational and elite athletes alike. Tears of the ACL are common in both male and female basketball players, with a higher incidence rate in females. Incidence of a retear to the existing graft or contralateral knee within 5 years of ACL reconstruction with patellar tendon autograft in young (less than 18 to 25 years of age), active basketball players can be as high as 52%. Reducing the number of ACL injuries or reinjury, of which there are an estimated 80 000 per year at an associated cost of over a billion dollars, can have significant potential long-term fiscal and health benefits. Following surgical reconstruction of the ACL, implementing a tailored rehabilitation protocol can ensure a successful return to sport. When searching the literature for such protocols, clinicians may struggle to find specific exercises, drills, and return-to-play criteria for particular sports. The intent of this manuscript is to present such a rehabilitation protocol for basketball. Level of Evidence Therapy, level 5.
Release site manipulation to favour European ground squirrel Spermophilus citellus translocations: translocation and habitat manipulation
Authors: Gedeon Csongor István , Boross Gábor , Németh András , Altbäcker Vilmos 
Published: March 2012

Translocating European ground squirrels Spermophilus citellus has become a popular conservation tool. However, few release techniques have been carefully evaluated. To contribute to an evidence‐based ground squirrel translocation guide for wildlife managers, we evaluated conditions of habitat manipulation (grass height and artificial burrow entrance angle) which we expected to affect settlement of translocated ground squirrels during the critical period after release. In a field experiment, we translocated 173 individuals in southeastern Hungary in 2007. We released the animals into angled or vertical artificial burrows and manipulated grass height. We found that animals preferred angled (∼ 30°) artificial burrows, which facilitate digging, and medium‐height grass (18 cm ± 1.5). Moreover, although ground squirrels generally are associated with short grass habitats, overhead protection by grasses is valuable after a translocation. This result implies that in order to accomplish a translocation, it is not sufficient to only know the habitat preference of a species in undisturbed situations, but also how and to what extent habitat characteristics should be manipulated to increase the chances of success.

AbstractThe effect of Mn addition on the microstructure, thermal and mechanical properties in as-cast and cold-rolled Al–Sc–Zr alloys was studied. Electrical resistometry, differential scanning calorimetry and microhardness measurements were used. Transmission electron microscopy, electron backscatter diffraction and X-ray diffraction of specimens quenched from temperatures of pronounced changes in resistivity helped to identify the microstructural processes responsible for resistivity changes. The distinct microhardness increase observed after annealing above ∼320°C is caused by precipitation of the Al3Sc particles. The cold-rolling prior to a heat treatment has no substantial effect on temperature position of the Al3Sc-phase precipitation. The formation of Al6Mn and/or Al6(Mn,Fe) particles is responsible for the intensive resistivity decrease of the cold-rolled materials compared to the as-cast materials. Precipitation of these particles has an insignificant effect on microhardness. The apparent activation energy for the precipitation of the Al3Sc particles was determined.
Strength and water permeability of concrete containing various types of fly ashes and filler material

Published: March 2012

Abstract
In this study, the strength and water permeability of concretes containing various types of fly ashes and filler material were investigated. Five types of fly ashes with two levels of fineness and ground-river sand were used to partially replace Portland cement at the dosages of 20 and 40% by weight. Results indicated that pulverized coal combustion fly ash produced concrete with good strength and low permeability. Normal fluidized bed combustion fly ashes containing very irregular particles with pores produced concrete with low strength and relatively low permeability. Fly ash from fluidized bed combustion of coal with bio-mass materials and fly ash with high amount of CaO and SO3 produced poor concretes with low strength and high permeability. The increase in fly ash fineness helped improve both strength and permeability of concrete due to the increase in the reactivity of fly ash. Filler material could also be used to replace Portland cement at low replacement level of 20% with small effects on strength and water permeability.

The dielectric constant (∊r) and the temperature coefficient of the resonant frequency (TCF) decreased, while the Qf value of the specimens increased with the increase in Ca2+ content. At the same Ca2+ content, the ∊r and Qf values of La3+-doped specimens were much higher than those of undoped ones. This is attributed to the elimination of oxygen vacancies by the solid solution of surplus La3+ with (Pb, Ca)2+. Excellent microwave dielectric properties of Qf

Published: March 2012

AbstractThe effects of electropulsing on microstructure changes and phase transformations of a tempered Mg-9Al-1Zn alloy sheet were investigated by using X-ray diffraction and transmission electron microscopy. The results indicate that with increasing frequency of electropulsing, precipitation and decomposition of β-phase were tremendously accelerated sequentially. The effects of electropulsing on single-point diamond turning processing were investigated by examining cutting force and surface roughness variations, and are discussed from the point of view of dislocation dynamics.
On the texture and grain growth in hot-deformed and annealed WE54 alloy
Authors: Azzeddine Hiba , Bradai Djamel 
Published: March 2012

AbstractA WE54 (Mg–Y–Nd–Zr) magnesium alloy was subjected to uniaxial and plane strain compression at two temperatures (300 and 400°C) and two strain rates (10–4and 10–2s–1). This processing resulted in a relative weakening of the initial strong basal texture of the as-received material. Contrarily to the conventional AZ31 alloy, the deformation texture was more or less insensitive to the processing parameters but depended strongly on the hot deformation type. Annealing treatments at 450°C up to 7 days resulted in normal grain growth. The grain growth annealing caused dissolution of the precipitates that had developed during hot deformation at 300°C. The grain growth kinetics can be described byDn= DRn+ kt, wherenwas found to range between 6 and 11. A net randomization of the texture was evidenced for all the deformation conditions.
Delayed neuromotor recovery and increased memory acquisition dysfunction following experimental brain trauma in mice lacking the DNA repair gene XPA

Published: March 2012

Object
This study investigates the outcome after traumatic brain injury (TBI) in mice lacking the essential DNA repair gene xeroderma pigmentosum group A (XPA). As damage to DNA has been implicated in neuronal cell death in various models, the authors sought to elucidate whether the absence of an essential DNA repair factor would affect the outcome of TBI in an experimental setting.

Methods
Thirty-seven adult mice of either wild-type (n = 18) or XPA-deficient (“knock-out” [n = 19]) genotype were subjected to controlled cortical impact experimental brain trauma, which produced a focal brain injury. Sham-injured mice of both genotypes were used as controls (9 in each group). The mice were subjected to neurobehavoral tests evaluating learning/acquisition (Morris water maze) and motor dysfunction (Rotarod and composite neuroscore test), pre- and postinjury up to 4 weeks. The mice were killed after 1 or 4 weeks, and cortical lesion volume, as well as hippocampal and thalamic cell loss, was evaluated. Hippocampal staining with doublecortin antibody was used to evaluate neurogenesis after the insult.

Results
Brain-injured XPA−/− mice exhibited delayed recovery from impairment in neurological motor function, as well as pronounced cognitive dysfunction in a spatial learning task (Morris water maze), compared with injured XPA+/+ mice (p < 0.05). No differences in cortical lesion volume, hippocampal damage, or thalamic cell loss were detected between XPA+/+ and XPA−/− mice after brain injury. Also, no difference in the number of cells stained with doublecortin in the hippocampus was detected.

Conclusions
The authors' results suggest that lack of the DNA repair factor XPA may delay neurobehavioral recovery after TBI, although they do not support the notion that this DNA repair deficiency results in increased cell or tissue death in the posttraumatic brain.
