    Most interpretations of sustainability in construction stem from the definition of sustainable development, which is a development that meets the needs of the present without compromising the future generation’s needs. Various research and sustainability studies within the construction industry focus on finding economical, social, and environmental balance. Construction professionals, such as Quantity Surveyors, begin their learning journey by studying in colleges and progressing to higher education. As the construction industry evolves through modern techniques, higher education institutions must also follow suit. These modern techniques have arisen due to the shift of ethos towards sustainability. Without the higher education institutions including this new knowledge in their curriculum, future professionals will not be equipped with the correct skills. Few research have been conducted in relation to students’ views on sustainability. Although such research is at a minute level, thus the converse side of the argument is how professional Quantity Surveyors view these topics on sustainability and whether they implement them in their daily duties. Hence, the research explores the differences in understanding between practicing and academic Quantity Surveyors on sustainable development in their various professional duties. The research was conducted using questionnaires that was distributed using survey monkey. The results were analysed through Spearman and ANOVA statistical tests to check their correlations. The study found a difference in the knowledge acquired by practicing and academic Quantity Surveyors. This finding conveys the importance of sustainability knowledge and how it is fundamental in achieving the UN sustainable goals and using such knowledge in practice

    Assessment of patients knowledge and attitude towards diabetes and its relationship with glycemic control: a cross-sectional study in a Nigerian tertiary hospital

    Get PDF
    Background: It is postulated that increased knowledge of patients about diabetes as well as a positive attitude will lead to improved glycaemic control and better outcome. The aim of this study was to determine the knowledge and attitude of diabetic patients in a tertiary hospital in Enugu and the relationship with their glycaemic control.Methods: A cross-sectional study was done using a structured questionnaire to obtain socio-demographic data and assess knowledge and attitude to diabetes on consecutive patients attending the outpatient clinic in a tertiary hospital. Responses were scored with equal weighting. The fasting blood glucose of the patients was measured and recorded.Result: There were 51(60.7%) females and 33 (39.3%) males, with majority (63.1%) in the age range 41 -64 years and 32(38.1%) had only primary education. The mean knowledge score was 6.19 ± 2.08 and 33(39.3%) demonstrated good knowledge. Knowledge did not differ between males and females (p=0.34), but was highest in those with tertiary education (p = 0.02). Positive attitude to the condition was recorded in 63(75%) subjects. There was poor correlation between knowledge and attitude (r = -0.161, p= 0.14). Those with good knowledge scores were 2 times more likely to have good glycaemic control compared with those with poor knowledge; OR = 2.015, p = 0.02. There was no significant difference between the glycemic control of those with good attitude and those with poor attitude (p= 0.08).Conclusion: Although overall knowledge was poor, patients had a good attitude to their illness. Knowledge, but not attitude was significantly positively associated with glycemic control.Keywords: Diabetes mellitus, Knowledge, Attitude, Glycaemic contro

    We have made a statistically complete, unbiased survey of C IV systems toward a region of high QSO density near the South Galactic Pole using 25 lines of sight spanning 1.5<z<2.81.5<z<2.8. Such a survey makes an excellent probe of large-scale structure at early epochs. We find evidence for structure on the 15−35h−115-35h^{-1} proper Mpc scale (H0≡100H_0 \equiv 100 km s−1s^{-1} Mpc−1{-1}) as determined by the two point C IV - C IV absorber correlation function, and reject the null hypothesis that C IV systems are distributed randomly on such scales at the ∌3.5σ\sim 3.5\sigma level. The structure likely reflects the distance between two groups of absorbers subtending ∌ 13×5×21h−3\sim~ 13 \times 5 \times 21h^{-3} and ∌7×1×15h−3\sim 7 \times 1 \times 15h^{-3} Mpc3^3 at z∌2.3z\sim 2.3 and z∌2.5z \sim 2.5 respectively. There is also a marginal trend for the association of high rest equivalent width C IV absorbers and QSOs at similar redshifts but along different lines of sight. The total number of C IV systems detected is consistent with that which would be expected based on a survey using many widely separated lines of sight. Using the same data, we also find 11 Mg II absorbers in a complete survey toward 24 lines of sight; there is no evidence for Mg II - Mg II or Mg II - QSO clustering, though the sample size is likely still small to detect such structure if it exists.Comment: 56 pages including 32 of figures, in gzip-ed uuencoded postscript format, 1 long table not included, aastex4 package.

    Effect of mineral fertilizer, pig manure, and Azospirillum rugosum on growth and nutrient contents of Lactuca sativa L

    Benefits from the application of plant growth-promoting bacteria in agriculture largely depend on the complex interactions between several factors including the nature of fertilizers selected. This study was designed to determine the fine tuning between the inoculated bacteria and different fertilizers and their effect on the growth of lettuce plants (Lactuca sativa L.). Plant growth promotion by a novel species of the genus Azospirillum, namely A. rugosum IMMIB AFH-6, was tested by biochemical, bioassay, and greenhouse studies. The treatments used in the greenhouse study were; unfertilized control (Blank), half recommended dose of chemical fertilizer (1/2CF), full recommended dose of chemical fertilizer (1CF), pig manure fertilizer (PMF), pig manure fertilizer + half recommended dose of chemical fertilizer (PMF + 1/2CF), and pig manure fertilizer + full recommended dose of chemical fertilizer (PMF + 1CF). All these treatments when inoculated with A. rugosum IMMIB AFH-6 inoculation were, respectively, In-Blank, In-1/2CF, In-1CF, In-PMF, In-PMF + 1/2CF, and In-PMF + 1CF. Significant increase in plant biomass and shoot N, P, Ca, and Fe was shown in the In-Blank treatment. Plant growth in soil amended with PMF and A. rugosum IMMIB AFH-6 was significantly lower than in soil treated with the chemical fertilizer, but inoculation combined with chemical fertilizer significantly elevated the plant biomass. The In-PMF + 1/2CF treatment showed the highest yield. A. rugosum IMMIB AFH-6 facilitated the accumulation of trace minerals in higher concentrations when PMF was combined with 1CF. To examine the benefits of inoculation by A. rugosum IMMIB AFH-6, we have proposed a new type of data analysis which considers both biomass and nutrient content of plants. This new type of analysis has shown the importance of the mineral content of plant

    Chern-Simons Reduction and non-Abelian Fluid Mechanics

    Get PDF
    We propose a non-Abelian generalization of the Clebsch parameterization for a vector in three dimensions. The construction is based on a group-theoretical reduction of the Chern-Simons form on a symmetric space. The formalism is then used to give a canonical (symplectic) discussion of non-Abelian fluid mechanics, analogous to the way the Abelian Clebsch parameterization allows a canonical description of conventional fluid mechanics.Comment: 12 pages, REVTeX; revised for publication in Phys Rev D; email to [email protected]

    High Temperature Electron Localization in dense He Gas

    Get PDF
    We report new accurate mesasurements of the mobility of excess electrons in high density Helium gas in extended ranges of temperature [(26≀T≀77)K][(26\leq T\leq 77) K ] and density [(0.05≀N≀12.0)atoms⋅nm−3][ (0.05\leq N\leq 12.0) {atoms} \cdot {nm}^{-3}] to ascertain the effect of temperature on the formation and dynamics of localized electron states. The main result of the experiment is that the formation of localized states essentially depends on the relative balance of fluid dilation energy, repulsive electron-atom interaction energy, and thermal energy. As a consequence, the onset of localization depends on the medium disorder through gas temperature and density. It appears that the transition from delocalized to localized states shifts to larger densities as the temperature is increased. This behavior can be understood in terms of a simple model of electron self-trapping in a spherically symmetric square well.Comment: 23 pages, 13 figure

    Hexatic-Herringbone Coupling at the Hexatic Transition in Smectic Liquid Crystals: 4-Ï”\epsilon Renormalization Group Calculations Revisited

    Full text link
    Simple symmetry considerations would suggest that the transition from the smectic-A phase to the long-range bond orientationally ordered hexatic smectic-B phase should belong to the XY universality class. However, a number of experimental studies have constantly reported over the past twenty years "novel" critical behavior with non-XY critical exponents for this transition. Bruinsma and Aeppli argued in Physical Review Letters {\bf 48}, 1625 (1982), using a 4−ϔ4-\epsilon renormalization-group calculation, that short-range molecular herringbone correlations coupled to the hexatic ordering drive this transition first order via thermal fluctuations, and that the critical behavior observed in real systems is controlled by a `nearby' tricritical point. We have revisited the model of Bruinsma and Aeppli and present here the results of our study. We have found two nontrivial strongly-coupled herringbone-hexatic fixed points apparently missed by those authors. Yet, those two new nontrivial fixed-points are unstable, and we obtain the same final conclusion as the one reached by Bruinsma and Aeppli, namely that of a fluctuation-driven first order transition. We also discuss the effect of local two-fold distortion of the bond order as a possible missing order parameter in the Hamiltonian.Comment: 1 B/W eps figure included. Submitted to Physical Review E.

    Crystallization of a classical two-dimensional electron system: Positional and orientational orders

    Full text link
    Crystallization of a classical two-dimensional one-component plasma (electrons interacting with the Coulomb repulsion in a uniform neutralizing positive background) is investigated with a molecular dynamics simulation. The positional and the orientational correlation functions are calculated for the first time. We have found an indication that the solid phase has a quasi-long-range (power-law) positional order along with a long-range orientational order. This indicates that, although the long-range Coulomb interaction is outside the scope of Mermin's theorem, the absence of ordinary crystalline order at finite temperatures applies to the electron system as well. The `hexatic' phase, which is predicted between the liquid and the solid phases by the Kosterlitz-Thouless-Halperin-Nelson-Young theory, is also discussed.Comment: 3 pages, 4 figures; Corrected typos; Double columne

    Trial to encourage adoption and maintenance of a Mediterranean diet (TEAM-MED): Protocol for a randomised feasibility trial of a peer support intervention for dietary behaviour change in adults at high cardiovascular disease risk

    © 2018 by the authors. Licensee MDPI, Basel, Switzerland. Adoption of a Mediterranean diet (MD) reduces cardiovascular disease (CVD) risk. However, interventions to achieve dietary behaviour change are typically resource intensive. Peer support offers a potentially low-cost approach to encourage dietary change. The primary objective of this randomised controlled trial is to explore the feasibility of peer support versus a previously tested dietetic-led intervention to encourageMDbehaviour change, and to test recruitment strategies, retention and attrition in order to inform the design of a definitive trial. A total of 75 overweight adults at high CVD risk who do not follow a MD (Mediterranean Diet Score (MDS ≀3)) will be randomly assigned to either: a minimal intervention (written materials), a proven intervention (dietetic support, written materials and key MD foods), or a peer support intervention (group-based community programme delivered by lay peers) for 12 months. The primary end-point is change in MDS from baseline to 6 months (adoption of MD). Secondary end-points include: change in MDS from 6 to 12 months (maintenance of MD), effects on nutritional biomarkers and CVD risk factors, fidelity of implementation, acceptability and feasibility of the peer support intervention. This study will generate important data regarding the feasibility of peer support for ease of adoption of MD in an ‘at risk’ Northern European population. Data will be used to direct a larger scale trial, where the clinical efficacy and cost-effectiveness of peer support will be tested
