Al‐Juaidi, Ahmed E., Jagath J. Kaluarachchi, and Ungtae Kim, 2010. Multi‐Criteria Decision Analysis of Treated Wastewater Use for Agriculture in Water Deficit Regions. Journal of the American Water Resources Association (JAWRA) 46(2):395‐411. DOI: 10.1111/j.1752‐1688.2009.00409.xAbstract:  Coastal regions such as the Gaza Strip of Palestine with limited freshwater supply suffer significantly due to the rapid depletion of water levels, seawater intrusion, and increased water demands. In such regions, use of treated wastewater (TWW) is a viable option if public health issues are addressed. The goal of this paper is to address the use of TWW in agriculture while considering net benefit, economic efficiency of water use (EEWU), environmental goals, and public health risks. The proposed methodology considers public health risk assessment and multi‐criteria decision analysis to assess the beneficial use of TWW in agriculture. The methodology was demonstrated for the Gaza Strip. The health risk assessment suggests that increasing the elapsed time between irrigation and consumption and switching from surface to sprinkler and drip irrigation are practical measures to reduce public health risks. The optimization and decision analyses show that proper allocation of freshwater and TWW and distribution of land area by crop type can significantly increase the net benefit and EEWU. In most cases, net benefit increased by 44%, groundwater use reduced 29% while increasing the EEWU by threefold compared with the existing conditions. The multi‐criteria decision analysis with weighted goal programming can develop flexible management options that considers a given decision‐maker preference. When groundwater abstraction for agriculture reduced from 57 to 36 Mm3 as per decision analysis, the corresponding area below mean sea level decreased by 58% indicating significant aquifer recovery.

Journal of the American Water Resources Association (JAWRA) 46(3):461‐472. DOI: 10.1111/j.1752‐1688.2009.00415.xAbstract:  In the Portland metropolitan area, suburban growth in cities such as Hillsboro is projected to increase as people seek affordable housing near a burgeoning metropolis. The most significant determinants for increases in water demand are population growth, climate change, and the type of urban development that occurs. This study analyzes the spatial patterns of single family residential (SFR) water consumption in Hillsboro, Oregon, at the census block scale. The following research questions are addressed: (1) What are the significant determinants of SFR water consumption in Hillsboro, Oregon? (2) Is SFR water demand sensitive to drought conditions and interannual climate variation? (3) To what magnitude do particular census blocks react to drought conditions and interannual climate variation? Using ordinary least squares multiple regression and spatial regression methods, we found that base use, representing indoor water use, is dependent on household size and that seasonal use, representing external water use is dependent on both education level and the size of the property’s outdoor space. Spatial analysis techniques determined that although the water demand of the study area as a whole is not sensitive to drought conditions, certain individual census blocks do respond with a higher magnitude of water use. The most climate‐sensitive census blocks tend to contain newer and larger homes, and have higher property values and more affluent and well‐educated residents.

Clark, Gregory M., 2010. Changes in Patterns of Streamflow From Unregulated Watersheds in Idaho, Western Wyoming, and Northern Nevada. Journal of the American Water Resources Association (JAWRA) 46(3):486‐497. DOI: 10.1111/j.1752‐1688.2009.00416.xAbstract:  Recent studies have identified a pattern of earlier spring runoff across much of North America. Earlier spring runoff potentially poses numerous problems, including increased risk of flooding and reduced summer water supply for irrigation, power generation, and migratory fish passage. To identify changing runoff patterns in Idaho streams, streamflow records were analyzed for 26 U.S. Geological Survey gaging stations in Idaho, western Wyoming, and northern Nevada, each with a minimum of 41 years of record. The 26 stations are located on 23 unregulated and relatively pristine streams that drain areas ranging from 28 to >35,000 km2. Four runoff parameters were trend tested at each station for both the period of historical record and from 1967 through 2007. Parameters tested were annual mean streamflow, annual minimum daily streamflow, and the dates of the 25th and 50th percentiles of the annual total streamflow. Results of a nonparametric Mann‐Kendall trend test revealed a trend toward lower annual mean and annual minimum streamflows at a majority of the stations, as well as a trend toward earlier snowmelt runoff. Significant downward trends over the period of historical record were most prevalent for the annual minimum streamflow (12 stations) and the 50th percentile of streamflow (11 stations). At most stations, trends were more pronounced during the period from 1967 through 2007. A regional Kendall test for water years 1967 through 2007 revealed significant regional trends in the percent change in the annual mean and annual minimum streamflows (0.67% less per year and 0.62% less per year, respectively), the 25th percentile of streamflow (12.3 days earlier), and the 50th percentile of streamflow (11.5 days earlier).

Published: January 2010

Background The goal of the current cadaver study was to compare two low-profile constructs for olecranon osteotomy repair: an intramedullary screw and tension band and a new olecranon nail. Methods Ten cadaveric elbow pairs were harvested. One of each pair was then randomly assigned to be tested either with a 6.5-mm intramedullary screw and tension band or with the olecranon nail. Using a testing apparatus to simulate an early postoperative motion protocol, the repairs were cyclically loaded. The maximal osteotomy gap observed during loading was recorded. A paired t-test was used for statistical anaylsis. Results The mean peak gap for the osteotomies repaired with the nail was 0.31 mm versus 0.75 mm for the screw. This difference was not statistically significant ( p = 0.158). Conclusion The data obtained demonstrate the olecranon nail performs favourably when compared with an intramedullary screw, with the added benefit of offering a low profile, intramedullary construct.

Published: January 2010

Background Concurrent evaluation of outcome measures is necessary to determine the most suitable measure(s) for a particular population. This property was evaluated in patients with rheumatic diseases undergoing shoulder surgery. Methods Three patient-reported measures (the Disabilities of the Arm, Shoulder and Hand Score; the Oxford Score; and the Shoulder Pain and Disability Index); three measures combining patient-reported and clinical outcomes (the Bostrom Shoulder Impairment Scale; the Constant Shoulder Score; and the Shoulder Function Assessment Scale); and one clinical measure (Range of Motion) were included. Responsiveness was expressed by the Standardized Response Mean (SRM). Results The study included 123 patients: 54 patients with shoulder arthroplasty (mean age 65.3 years) and 69 patients with non-arthroplasty (mean age 58.9 years). At 1 year, the Shoulder Function Assessment Scale was the most responsive measure in the arthroplasty group with SRM = 2.03 [95% confidence interval (CI) = 1.38 to 2.66] and Range of Motion (passive flexion) the least responsive measure with SRM = 0.54 (95% CI = 0.14 to 0.92). In the non-arthroplasty group, the Constant was the most responsive measure with SRM = 1.35 (95% CI = 0.87 to 1.83) and Range of Motion (passive flexion) the least responsive measure with SRM = 0.53 (95% CI = 0.16 to 0.90). Conclusion Measures comprising patient-reported outcomes were more responsive than clinical measures, and should be included when evaluating shoulder surgery in patients with rheumatic diseases.
A temporal perspective on population structure and gene flow in Atlantic salmon (Salmo salar) in Newfoundland, Canada

Published: January 2010

Studying population structure and gene flow patterns on temporal scales facilitates an evaluation of the consequences of demographic, physical, and environmental changes on the stability and persistence of populations. Here, we examine temporal genetic variation within and among Atlantic salmon ( Salmo salar ) rivers in Newfoundland and Labrador, Canada, using samples collected over a period of six decades (1951–2004). Our objective was to evaluate temporal changes in population connectivity associated with the closure of a commercial marine fishery. Despite demographic instability, we find that population structure remained temporally stable over more than 50 years. However, age structure can affect results when not taken into consideration, particularly in populations of large effective size where genetic drift is not strong. Where weak signals of genetic differentiation did not complicate analyses, contemporary migration was often asymmetric, yet low, suggesting patterns of intermittent gene flow. Nevertheless, we find some links between changes in population dynamics and contemporary gene flow. These findings may therefore imply that management decisions impacting the contemporary population dynamics of individual Atlantic salmon rivers can also affect the genetic stability of this species as a whole.
Reduced hatchery rearing density increases social dominance, postrelease growth, and survival in brown trout (Salmo trutta)
Authors: Brockmark Sofia , Johnsson Jörgen I. 
Published: January 2010

Hatchery fish reared for conservation or supplementation often have difficulties adapting to natural conditions, resulting in poor performance in the wild. In a standard hatchery, fish are confined at high densities, which creates a social environment different from that experienced after release. Here we investigated how rearing density influences social dominance, postrelease growth, and survival in brown trout ( Salmo trutta ). Fish were reared at three density treatments: conventional hatchery density, half of conventional hatchery density, and natural density. Four months after hatching, dominance status was determined, and 36 fish from each treatment were released into an enclosed stream and recaptured after 36 days. Trout reared at natural density had higher dominance status and grew faster, both in the hatchery and in the natural stream, than trout from higher densities. Moreover, trout reared at natural density were twice as likely to survive in the stream as trout from higher densities. These novel results suggest that more natural rearing densities would facilitate the development of adaptive behaviour in hatchery salmonids and, thereby, their contribution to natural production.

The ontogenetic changes in the feeding habits of the abalone Haliotis discus hannai were elucidated for the first time in natural habitats using stable isotope analyses. Abalone individuals were grouped into three developmental stages: small juveniles (<10 mm shell length (SL)), large juveniles (10–50 mm SL), and adults (>50 mm SL). The inferences of natural diets indicated that benthic diatoms, small red macroalgae and (or) juvenile brown macroalgae, and adult brown macroalgae were the primary food sources for small juveniles (6.5 ± 1.0 mm SL), large juveniles (23.7 ± 6.1 mm SL), and adults (81.8 ± 14.3 mm SL), respectively. The changes of δ13C in abalone were similar among three sampling stations and were explained by ontogenetic changes in feeding habits. The decrease of δ13C in abalone (≤20 mm SL) indicated a transition from diatom feeding to juvenile brown macroalgae and (or) small red macroalgae feeding, whereas the subsequent increase of δ13C (>20 mm SL) represented a feeding transition to adult brown macroalgae. These results prove the hypothesis of the ontogenetic changes in the feeding habits of the abalone H. discus hannai.
Geographic effects on American eel (Anguilla rostrata) life history characteristics and strategies
Authors: Jessop B. M. 
Published: January 2010

Latitudinal variability in length and age at maturity and annual growth rate for the American eel ( Anguilla rostrata ) along the Atlantic coast of North America was examined with respect to life history strategies and theory. Maturing (silver phase) female lengths and ages increased with increasing latitude (and distance) from the Sargasso Sea spawning site, as did male ages but not lengths. Growth rates for females (and males) declined with increasing latitude south of 44°N latitude, approximately the entrance to the Cabot Strait, but were constant or increased within the Gulf of St. Lawrence and St. Lawrence River, depending on the analysis method. The growing season and the number of degree-days ≥ 10 °C declined with increasing latitude. Female growth rates adjusted for the number of degree-days were approximately constant south of 44°N but increased further north, suggesting countergradient variation in growth. The temperature–size rule (increase in body size at lower temperatures) evidently applies to American eel females, but not males. No current life history model provides a satisfactory explanatory mechanism for the temperature–size rule and for anguillid life history strategies. A genetic link is proposed between increasing age (length) at elver and silver eel stages with increasing distance from the spawning area.
Analysis of ITS1 and ITS2 sequences in Ensis razor shells: suitability as molecular markers at the population and species levels, and evolution of these ribosomal DNA spacers

Published: January 2010

Internal transcribed spacer 1 and 2 (ITS1 and ITS2) sequences were analysed in Ensis razor shells (Mollusca: Bivalvia: Pharidae). We aimed to (1) test ITS1 and ITS2 as molecular markers at the population level in the successful alien E. directus (Conrad, 1843); (2) test these spacers at the species level in E. directus and three other Ensis species, E. siliqua (L., 1758), E. macha (Molina, 1782), and E. magnus (Schumacher, 1817); and (3) analyse the evolutionary processes that may be shaping Ensis ITS1 and ITS2 extant variation. In E. directus, despite the intragenomic divergence detected, ITS1 and ITS2 were informative in differentiating the geographic areas considered (Denmark and Canada) by means of both the insertion-deletion polymorphism and the nucleotide polymorphism. In this species, the 5.8S ribosomal gene (5.8S) showed scarce polymorphism. At the species level, maximum parsimony and maximum likelihood analyses revealed that ITS1 and ITS2 may be suitable to reconstruct Ensis phylogenetic relationships. Finally, the evolutionary models that best fit the long-term evolution of Ensis ITS1–5.8S–ITS2 are discussed. A mixed process of concerted evolution, birth-and-death evolution, and selection is chosen as an option that may reconcile the long-term evolution of Ensis ITS1–5.8S–ITS2 and 5S ribosomal DNA.
Microsatellites inBrassicaunigenes: relative abundance, marker design, and use in comparative physical mapping and genome analysis
Authors: Parida Swarup K. , Yadava Devendra K. , Mohapatra Trilochan 
Published: January 2010

Microsatellites present in the transcribed regions of the genome have the potential to reveal functional diversity. Unigene sequence databases are the sources of such genic microsatellites with unique flanking sequences and genomic locations even in complex polyploids. The present study was designed to assay the unigenes of Brassica napus and B. rapa for various microsatellite repeats, and to design markers and use them in comparative genome analysis and study of evolution. The average frequency of microsatellites in Brassica unigenes was one in every 7.25 kb of sequence, as compared with one in every 8.57 kb of sequence in Arabidopsis thaliana . Trinucleotide motifs coding for serine and the dinucleotide motif GA were most abundant. We designed 2374 and 347 unigene-based microsatellite (UGMS) markers including 541 and 58 class I types in B. napus and B. rapa, respectively, and evaluated their use across diverse species and genera. Most of these markers (93.3%) gave successful amplification of target microsatellite motifs, which was confirmed by sequencing. Interspecific polymorphism between B. napus and B. rapa detected in silico for the UGMS markers was 4.16 times higher in 5′ untranslated regions than in coding sequences. Physical anchoring of Brassica UGMS markers on the A. thaliana genome indicated their significance in studying the evolutionary history of A. thaliana genomic duplications in relation to speciation. Comparative physical mapping identified 85% of Brassica unigenes as single copy and gave clues for the presence of conserved primordial gene order. Complex chromosomal rearrangements such as inversions, tandem and segmental duplications, and insertions/deletions were evident between A. thaliana and B. rapa genomes. The results obtained have encouraging implications for the use of UGMS markers in comparative genome analysis and for understanding evolutionary complexities in the family Brassicaceae.

Published: January 2010

The purpose of this investigation was to identify the critical tasks encountered by correctional officers (COs) on the job and to conduct a comprehensive assessment and characterization of the physical demands of these tasks. These are the first steps in developing a fitness screening test for COs in compliance with recent legislation. The most important, physically demanding, and frequently occurring tasks were identified using Delphi methodology, focus groups, and questionnaire responses from 190 experienced front-line COs. These tasks were structured into emergency response scenarios for which a physical and physiological characterization was conducted to verify their relative physical demands analysis. Oxygen consumption and the forces exerted by COs were quantified while they were responding and then controlling and restraining inmates. The female COs used less force than the male COs did to control and restrain the same inmates (body control = 46 vs. 60 kg, wrist hold = 32 vs. 49 kg, and arm retraction = 37 vs. 47 kg) and did not exert their maximal strength during their control and restraint activities. The mean oxygen consumption of the female and male COs while performing the on-the-job tasks was similar (39.5 vs. 38.5 mL·kg–1·min–1). We concluded that the essential components of a fitness screening protocol for CO applicants are cell search, expeditious response, body control, arm restraint, inmate relocation, and an assessment of aerobic fitness. The criterion performance standards for completing these tasks in a circuit were set at the job performance level of safe and efficient female COs.
Reducing dietary sodium intake: the Canadian context
Authors: Barr Susan I. 
Published: January 2010

Sodium is a required nutrient; Adequate Intakes for adults range from 1200 to 1500 mg·day–1, depending on age. The Tolerable Upper Intake Level (UL) for sodium is 2300 mg·day–1 for adults, based on the relationship between sodium intake and increased blood pressure. Elevated blood pressure, which is prevalent among Canadians, is, in turn, a major risk factor for stroke, cardiovascular disease, and renal disease. Sodium intake is not the only determinant of blood pressure; other modifiable risk factors include relative mass, physical activity, overall dietary quality, and alcohol consumption. However, because >90% of adult Canadian men and two thirds of Canadian women have sodium intakes above the UL, Health Canada’s Working Group on Dietary Sodium Reduction has been charged with developing, implementing, and overseeing a strategy to reduce Canadians’ sodium intakes. It is estimated that ∼75% of dietary sodium is added during food processing; in addition to taste and palatability, sodium also has functional roles in food manufacturing and preservation, although the amounts used often exceed those required. Because of the central role of processed foods in sodium intake, the strategy proposed by Health Canada’s Working Group includes voluntary reduction of sodium in processed foods and foods sold in food service establishments. It will also include an education and awareness campaign, and research and surveillance. Initiatives to reduce sodium in other parts of the world have demonstrated that it will be challenging to reduce sodium intake to the recommended range and will likely require many years to accomplish.

Published: January 2010

We studied whether substitution of soy protein for casein can improve insulin sensitivity, lower blood pressure (BP), and inhibit protein kinase C βII (PKCβII) activation in kidney in an acquired model of metabolic syndrome. Adult male rats were fed 4 different diets: (i) starch (60%) and casein (20%) (CCD), (ii) fructose (60%) and casein (20%) (FCD), (iii) fructose (60%) and soy protein (20%) (FSD), and (iv) starch (60%) and soy protein (20%) (CSD). Renal function parameters, BP, pressor mechanisms, PKCβII expression, oxidative stress, and renal histology were evaluated after 60 days. FCD rats displayed insulin resistance and significant changes in body weight, kidney weight, urine volume, plasma and urine electrolytes accompanied by significant changes in renal function parameters compared with CCD rats. Elevated BP, plasma angiotensin-converting enzyme (ACE) activity, renal oxidative stress, and reduced nitrite (NO) and kallikrein activity were observed. Western blot analysis revealed enhanced renal expression of membrane-associated PKCβII in the FCD group. Histology showed fatty infiltration and thickening of glomeruli while urinary protein profile revealed a 5-fold increase in albumin. Substitution of soy protein for casein improved insulin sensitivity, lowered BP and PKCβII activation and restored renal function. Antioxidant action, inhibitory effect on ACE and PKCβII activation, and increased availability of kinins and NO could be contributing mechanisms for the benefits of dietary soy protein.
