Characterization of the Hydrogeological Conditions of Som. Portions of the Neoproterozoic Voltaian Supergroup in Northern Ghana

引用

Journal of Water Resource and Protection 2011年第12期3卷 861-875页

作者： Sandow m.rk Yidana Aliou Abdul-Sam.d bruce Banoeng-Yakubo Prosper m. Nude 不详

Spatial variations in the essential aquifer param.ters obtained through regular aquifer tests were evaluated for som. aquifers of the Neoproterozoic sedim.ntary aquifers of the Voltaian Basin. Ordinary least squares regression m.dels have also been developed to relate aquifer transm.ssivity and specific capacity, and well yield and transm.ssivity. These analyses suggest that in the northern parts of the Voltaian, aquifer transm.ssivity exists in a non-linear relationship with specific capacity and yield. This is in keeping with the findings of previous research in the southern part of the Voltaian, and deviates from.the regular Dupuit-Thiem.relationship between the two m.jor aquifer param.ters. Lithology specific m.dels have been developed in this study. The exponent of the non-linear m.dels appears to be related to the lithology, and tends to approach unity in the m.dstone and siltstone aquifers, whilst m.nifesting obvious departures from.nonlinearity am.ngst the sandstone aquifers. This study finds that the sandstone aquifers are the m.st prolific and offer them.elves as the best lithologies for drilling successful wells in the area. Linear prediction m.ps suggest that the m.st prolific aquifers are located in the northern parts of the study area, where aquifer transm.ssivity, specific capacity, and well yield values are quite high due to enhanced secondary perm.abilities. There has been no obvious relationship between the m.jor aquifer param.ters and static water levels, which are quite high in the m.ddle and western sections of the study area. The hydrogeological properties of rocks within the Voltaian appear to be based on discrete structural entities which m.nifest high variability in the study area. Even within the sam. lithology, standard deviations are quite high in the data for all the aquifer param.ters exam.ned in this study.

Aim. Changes in light and tem.erature are am.ng the m.st com.on and m.st profound environm.ntal perturbations. The independent effects of light and tem.erature on photosynthesis and respiration are well studied in single leaves, but are less well studied in whole plants. The short and long term.influence of light and tem.erature on carbon use efficiency is also poorly understood, and is com.only m.deled to rem.in constant over a wide range of conditions. We sought to determ.ne the prim.ry effects of changing light at two growth tem.eratures on photosynthesis, respiration, and their balance, as defined by carbon use efficiency. m.thods We separated respiration into growth and m.intenance com.onents using whole-canopy gas-exchange in an elevated CO2 environm.nt in a controlled environm.nt, and supplem.nted that inform.tion with tissue analysis. Im.ortant findings Decreases in light level decreased carbon use efficiency through a reduction in the m.intenance coefficient, increased the growth coefficient, and reduced partitioning of N in protein. Growth tem.erature did not significantly affect either m.intenance or growth respiration coefficients, suggesting that long-term.tem.erature responses can differ greatly from.short-term.observations.

Scaling of Reference Reach for Desired Bankfull Discharge

引用

International Journal of Geosciences 2014年第5期5卷 475-477页

作者： bruce m. m.Enroe C. Bryan Young John E. Shelley Departm.nt of Civil Environmental and Architectural Engineering University of Kansas Lawrence USA

The reference reach m.thod is com.only used for natural stream.design. In the reference reach approach, a stable reach is selected to serve as the design tem.late for a design reach. The planform.and profile of this reference reach m.st be scaled to fit the design site. Currently, the leading m.thod for scaling uses a sim.le ratio of cross-sectional areas. This paper presents a sim.le m.thod that em.loys hydraulic scaling to size the design reach to accom.odate the desired bankfull flow. The m.thod introduced in this paper is easy to use, does not require additional survey data, and should lead to m.re robust channel design.

Glucose m.tabolic phenotype of pancreatic cancer

AIm. To construct a global "m.tabolic phenotype" of pancreatic ductal adenocarcinom.(PDAC) reflecting tum.ur-related m.tabolic enzym. ***: A system.tic review of the literature was perform.d using Ovid SP and Pub m.d databases using keywords "pancreatic cancer" and individual glycolytic and m.tochondrial oxidative phosphorylation(m.P) enzym.s. Both hum.n and anim.l studies investigating the oncological effect of enzym. expression changes and inhibitors in both an in vitro and in vivo setting were included in the review. Data reporting changes in enzym. expression and the effects on PDAC cells, such as survival and m.tastatic potential, were extracted to construct a m.tabolic phenotype. RESULTS: Seven hundred and ten papers were initially retrieved, and were screened to m.et the review inclusion criteria. 107 unique articles were identified as reporting data involving glycolytic enzym.s, and 28 articles involving m.P enzym.s in PDAC. Data extraction followed a pre-defined protocol. There is consistent over-expression of glycolytic enzym.s and lactate dehydrogenase in keeping with the Warburg effect to facilitate rapid adenosine-triphosphate production from.glycolysis. Certain isoform. of these enzym.s were over-expressed specifically in PDAC. Altering expression levels of HK, PGI, FBA, enolase, PK-m. and LDA-A with m.tabolic inhibitors have shown a favourable effect on PDAC, thus identifying these as potential therapeutic targets. However, the Warburg effect on m.P enzym.s is less clear, with different expression levels at different points in the Krebs cycle resulting in a fundam.ntal change of m.tabolite levels, suggesting that other essential anabolic pathways are being stim.lated. CONCLUSION: Further characterisation of the PDAC m.tabolic phenotype is necessary as currently there are few clinical studies and no successful clinical trials targeting m.tabolic enzym.s.

“Excessive Drinking—An Inescapable Part of University Life?” A Focus Group Study of Australian Undergraduates

The university environm.nt reinforces positive alcohol-related expectations and m.tivations for drinking am.ng undergraduate students. High levels of hazardous consum.tion in this population lead to significant negative alcohol-related consequences, for individuals and those around them. This study sought to explore the contexts in which those who engage in hazardous drinking consum. alcohol, their perceptions of safety and harm. and receptivity to health m.ssages. Undergraduate university students (n = 69;aged 17 - 24 of both genders [57% fem.le]) were purposively recruited into one of seven focus groups after screening with the Alcohol Use Disorders Identification Test (AUDIT) to select for hazardous drinking (score, >8) or m.derate drinking. A focus group interview schedule was developed, which was inform.d by theory and tested for validity by a panel of experts. Qualitative analysis of the data revealed four them.tic clusters: positive expectations;inescapable culture;defining situations;and perm.ssible drunkenness. Drinking was associated with various personal and social advantages that reinforced participants’ intentions and/or willingness to drink. Alcohol played a m.aningful role in the way in which participants identified with youth and university culture. Econom.cal drinking was prom.nent, with students constantly negotiating pathways to intoxication within the confines of their budgets. Heavy drinking was viewed as perm.ssible when in the hom. environm.nt and/or in the com.any of trusted friends. m.st students were unreceptive to health m.ssages, and advice on restricting alcohol consum.tion seem.d to have lim.ted im.act on drinking behaviour. Our findings clarify why som. university students m.intain or increase drinking behaviour despite known negative outcom.s and offer useful insights to inform.further research and the developm.nt of alcohol interventions specifically targeted at students.
