    the complexity and unclear messages regarding drug policy changes. Conclusion Kenya, like many other African countries, is still far from achieving the Abuja targets. The government, with support from donors, should invest adequately in mechanisms that promote access to effective treatment. Such approaches should focus on factors influencing multiple dimensions of access and will require the cooperation of all stakeholders working in malaria control.

    Full Text Available ieving the Renewable Energy Target for Jamaica Abstract: The high cost of energy in Jamaica, one of the highest in the Caribbean region, is usually cited as a hindrance to industrial development and efficiency, especially in the manufacturing sector. High energy cost is also considered to be a national energy security issue and the government is taking steps to ensure adequate supply of energy at affordable prices. In the current National Development Plan, the government has set a target for renewable energy sources to supply 20% of the country's energy need by the year 2030. Using a linear programing model of energy planning, we examine how realistically this target could be achieved. Our findings indicate that the 20% renewable energy target is technically achievable with the optimal plan showing a mixture of wind power, hydropower and bagasse power but no solar power. However, when the timeline for investment in new generating capacities that will ensure the attainment of the target is considered, it becomes highly improbable that the target will be met. This study fills the gap that exists in evidence-based analysis of energy policy in Jamaica.

    2009-01-01

    This paper provides an overview of inflation targeting frameworks and macroeconomic performance under inflation targeting. Inflation targeting frameworks are generally quite similar across countries, and a broad consensus has developed in favor of "flexible" inflation targeting. The evidence shows that, although inflation target ranges are missed frequently in most countries, the inflation and growth performance under inflation targeting compares very favorably with performance under alternat...

    Heads of State and Governments of the Organization of African Unity now the African Union (AU) met in April 2001 at a Special Summit held in Abuja to address the challenges of HIV/AIDS, Tuberculosis, Malaria and other related infectious diseases in Africa. In May 2006, at the Special Summit under the theme: "Universal Access to HIV/AIDS, Tuberculosis and Malaria Services by 2010", the African Union Heads of States and Governments adopted the "Abuja Call for Accelerated Action towards Universal Access to HIV/AIDS, Tuberculosis and Malaria Services in Africa" and related commitments thus reaffirming earlier commitments. In July 2013, African leaders once again gathered in Abuja for the Abuja +12 summit, which focused on the theme 'Ownership, Accountability and Sustainability of HIV/AIDS, Tuberculosis and Malaria in Africa: Past, Present and the Future'. At the meeting, African leaders noted the tremendous progress that has been made in addressing HIV and AIDS, and made further commitments to effectively tackle the HIV epidemic on the continent. This article presents a critical look at each of these commitments and makes recommendations that would assist African countries in developing policies to end the HIV/AIDS epidemic in the region.

    Full Text Available Abstract Each year on the 25th April Africa and the rest of the world commemorate Africa Malaria Day as was agreed upon at the African Summit on Roll Back Malaria held in Abuja, Nigeria on 25th April 2000. The summit also called upon the United Nations to declare the period 2001–2010 a decade for malaria. The 1st Africa Malaria Day was commemorated with the theme "Communities Play a Central Role in Tackling Malaria". The 6th Africa Malaria Day was observed in 2006 with the theme "Get Your ACT Together" and the slogan "Universal Access to Effective Malaria Treatment is a Human Right". This article by the Secretariat of the Multilateral Initiative on Malaria (MIM was also part of the commemorations for the day. MIM was founded in 1997 as an alliance of institutions and individuals concerned with the malaria problem, and aiming at maximizing the impact of scientific research on malaria through strengthening African research capacity and coordinated global collaboration. The MIM Secretariat has been hosted in rotation by the founding institutions, and is being hosted for the first time in Africa by the African Malaria Network Trust (AMANET in Dar es Salaam, Tanzania. This article reviews the malaria situation in Africa six years after the Abuja Declaration, highlighting the disease burden trends, failures, achievements, challenges, and the way forward.

  8. Synergies and trade-offs in achieving global biodiversity targets.

    After their failure to achieve a significant reduction in the global rate of biodiversity loss by 2010, world governments adopted 20 new ambitious Aichi biodiversity targets to be met by 2020. Efforts to achieve one particular target can contribute to achieving others, but different targets may sometimes require conflicting solutions. Consequently, lack of strategic thinking might result, once again, in a failure to achieve global commitments to biodiversity conservation. We illustrate this dilemma by focusing on Aichi Target 11. This target requires an expansion of terrestrial protected area coverage, which could also contribute to reducing the loss of natural habitats (Target 5), reducing human-induced species decline and extinction (Target 12), and maintaining global carbon stocks (Target 15). We considered the potential impact of expanding protected areas to mitigate global deforestation and the consequences for the distribution of suitable habitat for >10,000 species of forest vertebrates (amphibians, birds, and mammals). We first identified places where deforestation might have the highest impact on remaining forests and then identified places where deforestation might have the highest impact on forest vertebrates (considering aggregate suitable habitat for species). Expanding protected areas toward locations with the highest deforestation rates (Target 5) or the highest potential loss of aggregate species' suitable habitat (Target 12) resulted in partially different protected area network configurations (overlapping with each other by about 73%). Moreover, the latter approach contributed to safeguarding about 30% more global carbon stocks than the former. Further investigation of synergies and trade-offs between targets would shed light on these and other complex interactions, such as the interaction between reducing overexploitation of natural resources (Targets 6, 7), controlling invasive alien species (Target 9), and preventing extinctions of native

When prompt recognition and laboratory confirmation is not achieved, this could lead to devastating genital discomfort and a major reason for frequent hospital visits.Aims: This was a cross-sectional prospective study that aimed to determine the prevalence and some associated risk factors of vulvovaginal candidiasis (VVC among nonpregnant women attending University of Abuja Teaching Hospital, Gwagwalada.Subjects and methods: A pair of high vaginal swab and endocervical swab samples was collected from each of 200 individual participating subjects. They were separately inoculated on Sabouraud's dextrose agar and incubated aerobically at 33°C for 48 hours. Ten percent KOH wet mount and Gram staining was done on swabs and colonies, respectively. Structured questionnaires were used to obtain sociodemographic and clinical data.Results: Of the 200 participating subjects, the prevalence of Candida albicans was 6.5% and that of non-albicans candidiasis 7.5%. Candidiasis was observed mostly among the 20- to 30-year age-group. All subjects with Candida-positive culture had been on antibacterial therapy prior to participating in this study – 28 (100%. There was a statistical relationship between the prevalence of VVC with previous antibacterial therapy (P<0.05, but not with age or other prevailing health conditions studied (P>0.05.Conclusion: The outcome of this study

Data were collected from 384 respondents using a structured interviewer-administered questionnaire. The participants were sampled randomly at antenatal care (ANC clinics in the five district hospitals in AMAC. Data analysis included descriptive statistics, cross-tabulations and measures of inequality. Logistic regression analysis was used to test the relationship between SECs (predictors and maternal healthcare service utilisation.Results: There were differentials in the utilisation of maternal healthcare services (ANC, delivery care, post natal care [PNC] and contraceptive services amongst women withdifferent SECs; and the payment system for maternal healthcare services was regressive. There were inconsistencies in the predictive effect of the SECs of women included in this study (age,education, birth order, location of residence, income group and coverage by health insurance on maternal healthcare service utilisation when considered independently (bivariate analysis as opposed to when considered together (logistic regression, with the exception of birth order, which showed consistent effect.Conclusion: SECs of women were predictive factors of utilisation of maternal healthcare services. There is a need for targeted policy measures and programme actions toward multiple SECs of women in their natural co-existing state in order to optimise maternal health benefits.

  11. What would it take to achieve the Paris temperature targets?

    Sanderson, Benjamin M.; O'Neill, Brian C.; Tebaldi, Claudia

    2016-07-01

    The 2015 Paris Agreement aims to limit warming to 2 or 1.5°C above preindustrial level, although combined Intended Nationally Determined Contributions (INDCs) are likely insufficient to achieve these targets. We propose a set of idealized emission pathways consistent with the targets. If countries reduce emissions in line with their INDCs, the 2°C threshold could be avoided only if net zero greenhouse gas emissions (GHGEs) are achieved by 2085 and late century negative emissions are considerably in excess of those assumed in Representative Concentration Pathway (RCP) 2.6 (net -5 Gt CO2/yr, compared with -1.5 Gt CO2/yr in RCP2.6). More aggressive near-term reductions would allow 2°C to be avoided with less end-of-century carbon removal capacity. A 10% cut in GHGEs by 2030 (relative to 2015) could likely achieve 2°C with RCP2.6 level negative emissions. The 1.5°C target requires GHGEs to be reduced by almost a third by 2030 and net zero by 2050, while a 50 year overshoot of 1.5°C allows net zero GHGEs by 2060.

    Full Text Available Yaws, one of the 17 neglected tropical diseases (NTDs, is targeted for eradication by 2020 in resolution WHA66.12 of the World Health Assembly (2013 and the WHO roadmap on NTDs (2012. The disease frequently affects children who live in poor socioeconomic conditions. Between 1952 and 1964, WHO and the United Nations Children's Fund (UNICEF led a global eradication campaign using injectable benzathine penicillin. Recent developments using a single dose of oral azithromycin have renewed optimism that eradication can be achieved through a comprehensive large-scale treatment strategy. We review historical efforts to eradicate yaws and argue that this goal is now technically feasible using new tools and with the favorable environment for control of NTDs. We also summarize the work of WHO's Department of Control of Neglected Tropical Diseases in leading the renewed eradication initiative and call on the international community to support efforts to achieve the 2020 eradication goal. The critical factor remains access to azithromycin. Excluding medicines, the financial cost of yaws eradication could be as little as US$ 100 million.The development of new tools has renewed interest in eradication of yaws; with modest support, the WHO eradication target of 2020 can be achieved.

    Full Text Available Objective. Infertility menstrual abnormalities continue to constitute a significant bulk of gynecological consultation in Africa. Both of these problems are sometimes traced to intrauterine adhesions which are preventable in the majority of cases. Study Design. A retrospective analysis of intrauterine adhesions at the National Hospital Abuja, Nigeria, was carried out, covering the period from 1st September 1999 to 1st September 2004. A total of 72 cases were analyzed. Statical analysis was done using 2. Results. The incidence of intrauterine adhesions was 1.73% of new patients. Mean age ± SD was 29.97±4.82 years. Patients who were Para 0 to 1 constituted 81.9% of the total. Intrauterine adhesions significantly (<0.02 occurred in nulliparae. The majority (68% were educated only up to secondary level which was significant (<0.05. Menstrual abnormalities were present in 90.3%. The commonest predisposing factor identified was a history of dilatation and curettage or uterine evacuation. Conclusion. Intrauterine adhesions are associated with lower educational status and low parity. Increasing educational targets nationally, poverty alleviation, nationwide retraining in manual vacuum aspiration, and wider application of this technique are recommended.

    Full Text Available Managing risks in construction projects has been acknowledged as a key direction process for the purposes of attaining the project goal in terms of time, cost, quality, safety, and environmental sustainability. Hence, the paper evaluated pre-construction and construction risks on active project sites in Abuja-Nigeria. This was achieved using survey method through the self-administration of 35 questionnaires to the professionals handling the 35 identified projects being undertaking at that time. Results showed that errors and omissions in design and improperly defined project scope had mean score values of 3.03 and 2.54, respectively, were the construction risks most experienced by the professionals during pre-construction. On the other hand, fluctuation in market prices and delays with mean score values of 3.14 and 2.74, respectively, were the construction risks experienced by the professionals during the construction phase of the projects. It is recommended that procurement methods such as construction management should be adopted and stakeholders should keep to their own side of the bargain to avoid unnecessary delays.

    Full Text Available Characterization of External Induced corrosion degradation of Ajaokuta- Abuja gas pipeline system was successfully carried out. The objective of this work is to analyze the mechanism of corrosion, analyze the effect of the corrosion on oil and gas pipeline and to evaluate the corrosion potential of a pipeline route. These were achieved by carrying out resistivity experiment on every one kilometer on the right of way (ROW of the pipeline. Soil and water aggressiveness test was also carried out on soil and water sample of the pipeline route respectively. The resistivity result was considerably high, chemical analysis revealed that the soil and wateracidity is between the pH of 6.7 and 8.2 respectively, which is moderately alkaline in nature, which makes the soil environment not conducive for pipelines due to potential for corrosion attack. The chloride content of the soil and water were also high. Based on the experimental results, it was proposed that the pipe should be laid on2-5m below the ground and that the galvanic anode for cathodic protection be located 1m below the ground, in order to avoid corrosion. It is therefore necessary to note that characterization of external corrosion is quite different from internal pipeline corrosion characterization.

    Full Text Available Elevated blood pressure (BP is one of the most important risk factors for cardiovascular (CV morbidity and mortality, and BP lowering is associated with reduction of coronary events. Despite this, less than one-third of hypertensive patients in Europe have adequate BP control. Improvement of the rates of adequate BP control and thereby a reduction of CV morbidity and mortality, currently represent a major challenge in the daily clinical practice. Many patients require two or more antihypertensives to achieve guideline-recommended BP targets. Findings from different studies have demonstrated that the fixed-dose combination (FDC perindopril/amlodipine is an effective and well tolerated treatment in patients uncontrolled with monotherapy, and in patients inadequately managed on another combination therapy. The perindopril/amlodipine FDC provides good rates of BP control in daily clinical practice. These good rates of BP control could be ex- plained by the synergistic mode of action of the two components, leading to enhanced BP lowering and reduced side effects, which may have a positive impact on treatment adherence. Krka’s perindopril/amlodipine FDC is available in the full range of doses, providing a flexible and effective treatment of hypertension.

  20. GHG emission reductions and costs to achieve Kyoto target

    2003-01-01

    Emission projection and marginal abatement cost curves (MACs) are the central components of any assessment of future carbonmarket, such as CDM (clean development mechanism) potentials, carbon quota price etc. However, they are products of very complex,dynamic systems driven by forces like population growth, economic development, resource endowments, technology progress and so on. Themodeling approaches for emission projection and MACs evaluation were summarized, and some major models and their results were compared.Accordingly, reduction and cost requirements to achieve the Kyoto target were estimated. It is concluded that Annex I Parties' total reductionrequirements range from 503-1304 MtC with USA participation and decrease significantly to 140-612 MtC after USA' s withdrawal. Totalcosts vary from 21-77 BUSD with USA and from 5-36 BUSD without USA if only domestic reduction actions are taken. The costs wouldsharply reduce while considering the three flexible mechanisms defined in the Kyoto Protocol with domestic actions' share in the all mitigationstrategies drops to only 0-16%.

    2003-10-01

    The Electric Tokamak (ET) at UCLA (t_pulse0.3V, B=0.25T) is now in a critical stage of research to exceed the conventional beta limit. The latest program is aiming for 10s long plasma discharges at unity peak beta by means of 2^d harmonic ICRF heating and current profile control. A stable computational MHD high beta path has been found for ET high aspect ratio configuration leading from the Troyon limit to unity beta using an in-house equilibrium code and the DCON stability code. This critical path involves high power ICRF injection (5MW) for targeted plasma heating and ballooning/kink modes stabilization by poloidal rotation. Another major component is high plasma density using core and edge fueling relying on kinetic neutral beam and inboard/outboard gas puff. At this regime current profile control using fast wave current drive, with bootstrap current optimization, will be possible. A magnetic well should develop, leading to high beta plasmas with omnigenous properties. To achieve these goals, a tight feedback system between power and particle injections and plasma diagnostics is mandatory.

  2. Evaluation of background ionising radiation levels within Gwagwalada town, Abuja

    The background ionising radiation levels within Gwagwalada Town, Abuja has been carried out using Atomtex 1117M Radiation Monitor. Readings were taken in twelve different locations. Twenty different readings were taken at each location and the mean equivalent dose rate was used to calculate the annual equivalent dose rate. A total of 240 measurements were taken across the 12 locations in the study Area. It was observed that the average dose equivalent varied from 0.105±0.008 μSv/h to 0.114±0.015μSv/h with a mean of 0.109±0.013 μSv/h. The mean value from Ungwan Bassa shows the highest equivalent dose rate while the equivalent dose rate from Phase 3 was the lowest. Ungwan Dodo, Ungwan Gwari recorded the second and third highest in-situ gamma radiation of 0.113±0.013 μSv/h and 0.112±0.012 μSv/h respectively. The result shows that the entire equivalent dose rates of all the locations were below the value of the Standard Background Radiation of 0.133 μSv/h. The study also revealed that the average annual equivalent dose rate is 0.192±0.005 mSv/y which is lower than the value of 1.0 mSv/yr averaged over five consecutive years according to the dose limit recommended by the International Commission on Radiological Protection (ICRP).

    Peter Ndoke NDOKE

    2006-07-01

    Full Text Available The quantity of carbon dioxide (CO2 contributed by automobile emissions to the environment was determined at some areas in Kaduna and Abuja in Northern Nigeria. Five census stations were selected in each of the two towns. In Kaduna, Jabi road in Ungwan Rimi, Kawo Motor park, Stadium round-about, Sabo and Kasuwa (Kaduna Main Market, were selected, while Asokoro (behind ECOWAS, Area One junction, A.Y.A. junction, Wuse market bus-stop, and Mabushi round-about were selected for Abuja. A gas sampling pump and tubes that could detect carbon dioxide were used to detect the quantity of CO2 in the environment at a certain time. The results obtained show a variation in the amount of CO2 in the environment. Areas with relatively heavy congestion show a high concentration of CO2, while areas with minimal traffic show a lower concentration of CO2. Sabo in Kaduna has an average concentration of 1840 ppm being the highest, while Asokoro (behind ECOWAS, Abuja has the least average concentration of 1160 ppm. Review of literature showed that increasing CO2 levels have adverse effects such as the Greenhouse Effect, which may lead to Global Warming, as well as a number of other climatic events. These concentrations are still not high enough to cause any serious health effects but they provide a baseline study for Policy makers and Town planners.

    Full Text Available BackgroundOur study group established "3H care" in 2002. The meaning of "3H care" attain and maintain adequate controls over hypertension, hyperlipidemia, and hyperglycemia in type 2 diabetic patients. This study evaluated the achievement of target goals after one year or more of "3H care" by specialists in our diabetic clinic.MethodsThis was a retrospective study of 200 type 2 diabetic patients who received "3H care" for one year or more in our diabetic clinic. We evaluated achievement of target goals for metabolic controls as suggested by the American Diabetes Association.ResultsOverall, 200 type 2 diabetes patients were enrolled, of whom 106 were males (53% and 94 were females (47%. After one year of "3H care," the mean HbA1c was 7.2±1.5% and the percentage of patients achieving glycemic control (HbA1c <7% was 51.8%. However only 32.2% of hypertensive patients achieved the recommended target. After one year of "3H care," the percentages of those who achieved the target value for dyslipidemia were 80.0% for total cholesterol, 66.3% for low density lipoprotein cholesterol, 57.9% for triglyceride, and 51.8% for high density lipoprotein cholesterol. The percentage that achieved all three targets level was only 4.4% after one year and 14.8% after two years.ConclusionThe results of this study demonstrate that only a minor proportion of patients with type 2 diabetes achieved the recommended goals despite the implementation of "3H care." It is our suggestion that better treatment strategies and methods should be used to control hypertension, hyperlipidemia and hyperglycemia.

  7. Low Density Lipoprotein Cholesterol Target Goal Attainment Rate and Physician Perceptions about Target Goal Achievement in Korean Patients with Diabetes

    Jenie Yoonoo Hwang

    2011-12-01

    Full Text Available BackgroundThis study aims to investigate the discrepancy between clinicians' perceptions and actual achievement rates of low density lipoprotein cholesterol (LDL-C in Korean patients with diabetes according to updated American Diabetes Association (ADA/American College of Cardiology Foundation (ACC recommendations.MethodsThis is a multi-center, retrospective, non-interventional, observational study. Diabetic patients aged 18 years or older were eligible if they had been diagnosed with hypercholesterolemia or were receiving a lipid-lowering therapy between May 2010 and August 2010. The information was obtained by reviewing medical records and using a self-completed questionnaire to examine physician perceptions.ResultsA total of 2,591 subjects who satisfied the inclusion criteria were enrolled. Highest-risk and high-risk patients accounted for 61.9% and 38.1% of the patients, respectively. Although most (96.3% underwent a statin monotherapy or a statin-based combination therapy, just 47.4% of patients attained the LDL-C target. However, the physicians' perceptions on target achievement rate (70.6% were different from the actual results (47.4%. Many patients (65.3% remained on the starting doses of statins, despite evidence of poor achievement of lipid goals.ConclusionOnly less than half of patients with diabetes attained the LDL-C goal. The surveys showed that poor physician performance might be due to the lack of recognition on ADA/ACC consensus causing a low LDL-C target attainment rate. Therefore, changes in doctor perception are needed to attain target LDL-C level and reduce cardiovascular risk in Korean patients with diabetes.

Descriptive statistics and comparison of continuous variables were produced.Results: Mean (SD HbA1c was 8.30% (±1.5 with no statistical difference between patients with type 1 and type 2 diabetes (P = 0.44. Sixteen percent of patients (12% type 1, 31% type 2 had an HbA1c of <7%. Eighty-three percent of patients had blood pressure ≤130/80 mmHg. Sixteen percent of patients with type 1 and 37% with type 2 diabetes were achieving combined lipid targets. Only 34% and 9% of patients who had an indication (and no documented contraindication for lipid-lowering and antiplatelet therapy, respectively, were prescribed such agents. There was a significant difference in achievement of macrovascular treatment targets in patients with type 1 and type 2 diabetes, but no difference in screening or treatment outcomes in microvascular disease. Patients below the age of 25 years were less likely to achieve macrovascular treatment targets.Conclusion: A large number of young adult patients with diabetes mellitus do not achieve recognized

  9. A method to achieve rapid localised deep heating in a laser irradiated solid density target

    Schmitz, Holger

    2016-01-01

    Rapid heating of small buried regions by laser generated fast electrons may be useful for applications such as XUV radiation sources or as drivers for shock experiments. In non-structured targets the heating profile possesses a global maximum near the front surface. This paper presents a new target design that uses resistive guiding to concentrate the fast electron current density at a finite depth inside the target. The choice of geometry uses principles of non-imaging optics. A global temperature maximum at depths up to 50{\\mu}m into the target is achieved. Although theoretical calculations suggest that small source sizes should perform better than large ones, simulations show that a large angular spread at high intensities results in significant losses of the fast electrons to the sides. A systematic parameter scan suggests an optimal laser intensity. A ratio of 1.6 is demonstrated between the maximum ion temperature and the ion temperature at the front surface.

  11. Average Minimum Transmit Power to achieve SINR Targets: Performance Comparison of Various User Selection Algorithms

    Salim, Umer

    2010-01-01

    In multi-user communication from one base station (BS) to multiple users, the problem of minimizing the transmit power to achieve some target guaranteed performance (rates) at users has been well investigated in the literature. Similarly various user selection algorithms have been proposed and analyzed when the BS has to transmit to a subset of the users in the system, mostly for the objective of the sum rate maximization. We study the joint problem of minimizing the transmit power at the BS to achieve specific signal-to-interference-and-noise ratio (SINR) targets at users in conjunction with user scheduling. The general analytical results for the average transmit power required to meet guaranteed performance at the users' side are difficult to obtain even without user selection due to joint optimization required over beamforming vectors and power allocation scalars. We study the transmit power minimization problem with various user selection algorithms, namely semi-orthogonal user selection (SUS), norm-based...

  14. Achieving targeted and quantifiable alteration of mRNA splicing with Morpholino oligos

    This work represents the first guide for using steric-block antisense oligos as tools for effective and targeted modification of RNA splicing. Comparison of several steric-block oligo types shows the properties of Morpholinos provide significant advantages over other potential splice-blocking oligos. The procedures and complications of designing effective splice-blocking Morpholino oligos are described. The design process requires complete pre-mRNA sequence for defining suitable targets, which usually generate specific predictable messengers. To validate the targeting procedure, the level and nature of transcript alteration is characterized by RT-PCR analysis of splice modification in a β-globin splice model system. An oligo-walking study reveals that while U1 and U2 small nuclear RiboNucleoProtein (snRNP) binding sites are the most effective targets for blocking splicing, inclusion of these sites is not required to achieve effective splice modifications. The most effective targeting strategy employs simultaneously blocking snRNP binding sites and splice-junctions. The work presented here continues to be the basis for most of the successful Morpholino oligos designed for the worldwide research community to block RNA splicing

  15. Why use of interventions targeting outdoor biting mosquitoes will be necessary to achieve malaria elimination

    Nicodem James Govella

    2012-06-01

    Full Text Available By definition, elimination of malaria means permanent reduction to zero of locally incidence of infections. Achieving this goal among other reasons, it requires fully understanding on where and when persons are most exposed to malaria vectors as these are fundamental for targeting interventions to achieve maximum impact. While elimination can be possible in some settings with low malaria transmission intensity and dominated with late and indoor biting of vectors using Long Lasting Insecticidal Nets (LLIN and Indoor Residual Spraying (IRs, it’s difficult and even impossible in areas with high and where majority of human exposure to transmission occurs outside human dwellings. Recently in response to wide spread use of LLIN and IRS, human risk of exposure to transmission is increasingly spread across the entire night so that much of it occurs outdoors and before bed time. This modification of vector populations and behaviour has now been reported from across Africa, Asia and from the Solomon Islands. Historical evidence shows that even in areas with intervention coverage exceeding 90% of human population it was so hard to even push prevalence down below the pre elimination threshold of 1% being compromised mainly with the outdoor residual transmission. Malaria control experts must however continue to deliver interventions that tackle indoor transmission but considerable amount of resources that target mosquitoes outside of houses and outside of sleeping hours will therefore be required to sustain and go beyond existing levels of malaria control and achieve elimination.

    Aungier, S P M; Roche, J F; Diskin, M G; Crowe, M A

    2014-01-01

    The aims of the present study were to investigate (1) the risk factors that influence the achievement of reproductive targets postpartum (pp) and (2) the key factors that influence pregnancy rate following first artificial insemination (AI) in dairy cows. Ninety-eight Holstein-Friesian pp cows were blood sampled from wk 1 to 4 pp for hematology and biochemistry. Reproductive tract health was assessed weekly by ultrasonography and vaginal mucus scoring. Body condition score (BCS), lameness score, and milk yield were assessed every 2 wk. Milk samples for progesterone assay were collected twice weekly and on d 4, 5, and 7 after AI. Risk factors associated with achieving reproductive targets depended on (1) increased metabolic activity of the liver (increased glutamate dehydrogenase at calving and increased γ-glutamyl transpeptidase in wk 4), (2) a competent immune system (increased neutrophils in wk 1; decreased α1-acid glycoprotein in wk 1, 2, and 3), (3) an endocrine system that was capable of responding by producing sufficient triiodothyronine in wk 2 and increased insulin-like growth factor I in wk 3 and 4, (4) a lower negative energy balance status (decreased nonesterified fatty acid concentration in wk 1; decreased β-hydroxybutyrate concentration in wk 2; BCS loss between calving and d 28 pp factors that increased the odds of a successful first AI were previous ovulation(s) (odds ratio=3.17 per ovulation), BCS >2.5 at AI (odds ratio=3.01), and clear vaginal mucus (score=0) compared with purulent mucus (score >0) 4 d after first AI (odds ratio=2.99). In conclusion, this study identified key risk factors in the early pp period that give a higher probability of cows achieving their reproductive targets and of having a first-AI pregnancy.

  20. Optimal models with maximizing probability of first achieving target value in the preceding stages

    林元烈; 伍从斌; 康波大

    2003-01-01

    Decision makers often face the need of performance guarantee with some sufficiently high proba-bility. Such problems can be modelled using a discrete time Markov decision process (MDP) with a probabilitycriterion for the first achieving target value. The objective is to find a policy that maximizes the probabilityof the total discounted reward exceeding a target value in the preceding stages. We show that our formula-tion cannot be described by former models with standard criteria. We provide the properties of the objectivefunctions, optimal value functions and optimal policies. An algorithm for computing the optimal policies forthe finite horizon case is given. In this stochastic stopping model, we prove that there exists an optimal deter-ministic and stationary policy and the optimality equation has a unique solution. Using perturbation analysis,we approximate general models and prove the existence of ε-optimal policy for finite state space. We give anexample for the reliability of the satellite systems using the above theory. Finally, we extend these results tomore general cases.

  1. Assessment of antimicrobial drug residues in beef in Abuja, the Federal Capital Territory, Nigeria.

    Omeiza, Gabriel K; Ajayi, Itopa E; Ode, Okwoche J

    2012-01-01

    Drugs administered to food-producing animals close to the time of slaughter often result in prohibited antimicrobial residues in the animal tissues at slaughter. Evidence based on the Premi® test confirmed the occurrence of antimicrobial drug residues in 89.3% of kidney and urine samples from cattle slaughtered within Abuja town where the residents rely heavily on beef as a source of protein. The administration of antibiotics close to the time of slaughter by marketers/herd owners and transporters was found to be significantly (p<0.05) higher when compared with butchers and abattoir workers. The practice of administering antibiotics to animals close to the time of slaughter was believed to be profit-motivated. The research suggests that awareness campaigns amongst the stakeholders, the enactment of appropriate laws for the control of antibiotic use and the empowerment of veterinary public health practitioners in food regulatory agencies as some of the strategies which may positively reduce the risk of antimicrobial drug residues in food animals in Nigeria.

  2. Effects of gamma irradiation on fungal load and Mycotoxin on Sesame seeds in Abuja, Nigeria

    Gamma rays of average energy of 1.25 MeV from radionuclide 60Co was used in this study and the effects of varying doses 3, 6, 9, 12, 15 kGy on fungal load of and mycotoxin content on sesame seeds were investigated. Sesame seed samples were collected from Abaji, Gwagwalada, Kubwa and Karu markets in Abuja, Federal Capital Territory, Nigeria. A serial dilution technique was employed and the fungi so diluted from the sesame seed samples were identified based on micro and macro morphological characteristics. The Aflatoxin Total and Ochratoxin A Contents in the samples were analysed using AgraQaunt direct combative enzyme-linked immunosorbent assay (ELISA). In all, 157 fungal isolates to four genera: Aspergillus, Curvularia, Penicillium, and Fusarium spp. in decreasing order of predominance were identified. Aspergillus spp. were observed from all the nonirradiated samples. Doses of 6-15kGy eliminated the entire fungal load. Also doses of 9-15kGy generally reduced Ochratoxin A content in all the samples, the rate of mycotoxin reduction was inconsistent with absorbed dose. However, sesame seed samples from the four markets exposed to irradiation dose of 15kGy had the comparatively least Aflatoxin Total content.

    2013-03-01

    Full Text Available Clay deposits in the Federal Capital Territory of Abuja were investigated with a view to categorizing them in order to determine their suitability as insulating refractory material. Thesamples were collected from three different locations in the territory, namely Sheda, Abaji and Karimu, and labeled A, B, and C. In order toproject a better representation of the territory, the samples were mined from ten cites each. The mined clay samples from the ten cites were mixed properly and a representative specimen for test from that location was produced using the cone and quartering system as recommended by the American Society of Testing Materials (ASTM. Atomic Absorption Spectrometer(AAS was used to determine the chemical composition, while other established processes were used to determine other insulating properties likeparticle size distribution, specific gravity, bulk density, solid density, water absorption, apparent porosity, permeability to air, refractoriness, thermal shock resistance, modulus of rupture, linear shrinkage and thermal conductivity. The chemical analysis showed that all the samples had high percentages of silica and alumina, thereby classifying them as Alumino-silicates.

    Full Text Available This study aims to examine public and private school teachers’ opinions on different aspects of their professional associations and provisions and also asks principals about teachers’ conduct and their views on the Nigerian curriculum. To conduct this study, qualitative and quantitative research models were used to investigate differences between the two organizations. Quantitative data was collected by distributing questionnaires to 118 teachers in the Abuja Municipal Area Council (AMAC, Nigeria. To conduct the qualitative analysis, 15 teachers from two schools were selected (a total of 30 teachers to answer 5 discussion questions concerning their views on the Nigerian educational system. The findings revealed that private school teachers are at an advantage when it comes to provision of resources and technology, professional development and to some degree salaries. Both public and private school teachers felt being a teacher did not bring them respect in their community. Government policy makers need to study private schools and how they operate to see how they can make changes to produce the revolutionary reform needed in education. 30 principals’ interviews revealed that public school teachers are not easily held accountable for misconduct due to the structure of leadership, while private school teachers are held accountable and any form of unprofessionalism easily leads to termination of employment.

    The International Target Values (ITVs) are reasonable uncertainty estimates that can be used in judging the reliability of measurement techniques applied to industrial nuclear and fissile materials subject to accountancy and/or safeguards verification. In the absence of relevant experimental estimates, ITVs can also be used to select measurement techniques and calculate sample population during the planning phase of verification activities. It is important to note that ITVs represent estimates of the 'state-of-the-practice', which should be achievable under routine measurement conditions affecting both facility operators and safeguards inspectors, not only in the field, but also in laboratory. Tabulated values cover measurement methods used for the determination of volume or mass of the nuclear material, for its elemental and isotopic assays, and for its sampling. The 2010 edition represents the sixth revision of the International Target Values (ITVs), issued by the International Atomic Energy Agency (IAEA) as a Safeguards Technical Report (STR-368). The first version was released as 'Target Values' in 1979 by the Working Group on Techniques and Standards for Destructive Analysis (WGDA) of the European Safeguards Research and Development Association (ESARDA) and focused on destructive analytical methods. In the latest 2010 revision, international standards in estimating and expressing uncertainties have been considered while maintaining a format that allows comparison with the previous editions of the ITVs. Those standards have been usually applied in QC/QA programmes, as well as qualification of methods, techniques and instruments. Representatives of the Brazilian Nuclear Energy Commission (CNEN) and the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) participated in previous Consultants Group Meetings since the one convened to establish the first list of ITVs released in 1993 and in subsequent revisions

    Objective:To detect IgG antibody toChlamydophila pneumoniae(CP)in sera ofHIV/AIDS patients and provide rationale for inclusion of routine screening for anti-CP antibodies and anti-chlamydial agents in the Nigerian NationalHIV/AIDS Management Plan.Methods: Serum samples from34 consentingHIV/AIDS patients attended a Government-approved Antiretroviral Treatment Facility in Abuja were screened by enzyme-linked immunosorbent assay for anti-CP IgG antibody using ImmunoComb® Chlamydia Bivalent IgG Test kit (Orgenics, Israel).Results:Anti-CP IgG antibody was detected in20 (58.8%)of34 patients tested. The detection rate was higher among the males(8/13; 61.5%) than the females (12/21; 57.1%). Patients of the age group 16-30 years had the highest(7/10; 70%) detection of anti-CP IgG antibody.Conclusions:The result of the present study suggests the presence of anti-CP antibodies in sera of the HIV/AIDS patients, and reinforces the need for routine screening for anti-CPantibodies as a necessary intervention to reduce the burden ofChlamydophila pneumoniae (C. pneumoniae) infections and to reduceHIV-positive morbidity in Nigeria. The outcome of this study also provides justification for the possible inclusion of anti-chlamydial agents in the NationalHIV/AIDS Management Plan to provide prophylaxis against or treat activeC. pneumoniae infections.

    Full Text Available Access to farm inputs is one of the major challenges facing rural farmers in Nigeria. To alleviate this problem, government at different levels strongly recommended the formation of cooperative societies to farmers. Against this background, a study was conducted to determine if differential access to farm inputs exists between cooperative and non-cooperative farmers in Abuja, Nigeria. A multi-stage technique was used for sample selection while semi-structured questionnaires were used for data collection. A total of 360 farmers were randomly interviewed in four agricultural zones (180 cooperative and 180 non-cooperative farmers. Data were analyzed using two-way factorial analysis of variance (ANOVA and mean separation was done at 5% probability level. Results revealed that there was significant difference (P < 0.01 in cooperative and non-cooperative farmers’ access to farm inputs. Comparatively, the mean perceptions indicated that the cooperative farmers had more access to labour, loan, herbicide, insecticide, rodenticide, fertilizer, tractor services, storage equipment and processing equipment while the non-cooperative farmers had more access to land. The results also indicated that the most accessible farm input to both cooperative and non-cooperative farmers was land while the least accessible farm inputs were loan and tractor services. Based on the findings, the paper concluded that differential access to farm inputs existed between cooperative and non-cooperative farmers in the study area. It was recommended that government and non-governmental agencies should encourage farmers to form and/or join viable cooperative societies.Key words: cooperative societies, least accessible farm inputs, mean perception, most accessible farm input, small-scale farmers,

    2015-04-01

    Background.  The Pan-American Health Organization has called for reducing (1) human immunodeficiency virus (HIV) mother-to-child transmission (MTCT) to ≤0.30 infections/1000 live births (LB), (2) HIV MTCT risk to ≤2.0%, and (3) congenital syphilis (CS) incidence to ≤0.50/1000 LB in the Americas by 2015. Methods.  Using published Brazilian data in a mathematical model, we simulated a cohort of pregnant women from antenatal care (ANC) through birth. We investigated 2 scenarios: "current access" (89.1% receive one ANC syphilis test and 41.1% receive 2; 81.7% receive one ANC HIV test and 18.9% receive birth testing; if diagnosed, 81.0% are treated for syphilis and 87.5% are treated for HIV) and "ideal access" (95% of women undergo 2 HIV and syphilis screenings; 95% receive appropriate treatment). We conducted univariate and multivariate sensitivity analyses on key inputs. Results.  With current access, we projected 2.95 CS cases/1000 LB, 0.29 HIV infections/1000 LB, 7.1% HIV MTCT risk, and 11.11 intrauterine fetal demises (IUFD)/1000 pregnancies, with significant regional variation. With ideal access, we projected improved outcomes: 1.00 CS cases/1000 LB, 0.10 HIV infections/1000 LB, HIV MTCT risk of 2.4%, and 10.65 IUFD/1000 pregnancies. Increased testing drove the greatest improvements. Even with ideal access, only HIV infections/1000 LB met elimination goals. Achieving all targets required testing and treatment >95% and reductions in prevalence and incidence of HIV and syphilis. Conclusions.  Increasing access to care and HIV and syphilis antenatal testing will substantially reduce HIV and syphilis MTCT in Brazil. In addition, regionally tailored interventions reducing syphilis incidence and prevalence and supporting HIV treatment adherence are necessary to completely meet elimination goals. PMID:26180825

    Full Text Available Background: Stroke is the second leading cause of death and the leading cause of adult disability worldwide. A better understanding of stroke risk factors and outcome may help guide efforts at reducing the community burden of stroke. This study aimed to understand stroke risk factors, imaging subtypes, and 30-day outcomes among adult Nigerians. Materials and Methods: We prospectively recruited all patients presenting with acute stroke at the National Hospital Abuja between January 2010 and June 2012. We assessed clinical and laboratory variables, as well as brain computerized tomography, magnetic resonance imaging, and carotid Doppler ultrasound scans. We also assessed case fatality and functional outcome at 30 days after stroke. Results: Of 272 patients studied, 168 (61.8% were males. Age at presentation (mean ± standard deviation was 56.4 ± 12.7 years in males and 52.9 ± 14.8 years in females ( P = 0.039. Neuroimaging was obtained in 96.7% patients, revealing cerebral infarction (61.8%, intracerebral hemorrhage (ICH (34.8%, and subarachnoid hemorrhage (SAH (3.4%. Carotid plaques or stenosis ≥50% were detected in 53.2% patients with cerebral infarction. Stroke risk factors included hypertension (82.7%, obesity (32.6%, diabetes (23.5%, hyperlipidemia (18.4%, atrial fibrillation (9.2%, and cigarette smoking (7.7%. At 30 days after stroke, case-fatality rate was 18.8%, whereas modified Rankin Scale (mRS scores for cerebral infarction, ICH, and SAH were 3.71, 4.21, and 4.56, respectively. Atrial fibrillation, a previous stroke, and age older than 50 years were all associated with worse mRS scores at 30 days. Conclusion: Although hypertension, obesity, diabetes mellitus, and atrial fibrillation were important stroke risk factors, in many patients, these were detected only after a stroke. While the commonest stroke subtype was cerebral infarction, observed in almost two-third of patients, SAH was associated with the highest case-fatality rate at

    Within the European Union (EU) a paradigm shift is currently occurring in the waste sector, whereEU waste directives and national waste strategies are placing emphasis on resource efficiency andrecycling targets. The most recent Danish resource strategy calculates a national recycling rate of22% for household waste, and sets an ambitious goal of a 50% recycling rate by 2020. This studyintegrates the recycling target into the FRIDA model to project how much waste and from whichstreams should b...

  14. Determinants for achieving the LDL-C target of lipid control for secondary prevention of cardiovascular events in Taiwan.

    Li-Ting Ho

    Full Text Available Epidemiological and clinical studies have clearly established the link between low-density lipoprotein cholesterol (LDL-C and atherosclerosis-related cardiovascular consequences. Although it has been a common practice for physicians to prescribe lipid-lowering therapy for patients with dyslipidemia, the achievement rate is still not satisfied in Taiwan. Therefore, the determinants for achieving the LDL-C target needed to be clarified for better healthcare of the patients with dyslipidemia.This registry-type prospective observational study enrolled the patients with cardiovascular diseases (coronary artery disease (CAD and cerebrovascular disease (CVD from 18 medical centers across Taiwan, and clinically followed them for five years. At every clinical visit, vital signs, clinical endpoints, adverse events, concurrent medications and laboratory specimens were obtained as thoroughly as possible. The lipid profile (total cholesterol, high-density lipoprotein cholesterol, LDL-C, triglyceride, liver enzymes, and creatinine phosphokinase were evaluated at baseline, and every year thereafter. The cross sectional observational data was analyzed for this report.Among the 3,486 registered patients, 54% had their LDL-C < 100 mg/dL. By univariate analysis, the patients achieving the LDL-C target were associated with older age, more male sex, taller height, lower blood pressure, more under lipid-lowering therapy, more smoking cessation, more history of CAD, DM, physical activity, but less history of CVD. The multivariate analysis showed statin therapy was the most significant independent determinant for achieving the treatment target, followed by age, history of CAD, diabetes, blood pressure, and sex. However, most patients were on regimens of very-low to low equipotent doses of statins.Although the lipid treatment guideline adherence is improving in recent years, only 54% of the patients with cardiovascular diseases have achieved their LDL-C target in Taiwan

  15. Engineering fusogenic molecules to achieve targeted transduction of enveloped lentiviral vectors

    2009-06-01

    Full Text Available Abstract Background Lentiviral vectors with broad tropism are one of the most promising gene delivery systems capable of efficiently delivering genes of interest into both dividing and non-dividing cells while maintaining long-term transgene expression. However, there are needs for developing lentiviral vectors with the capability to deliver genes to specific cell types, thus reducing the "off-target" effect of gene therapy. In the present study, we investigated the possibility of engineering the fusion-active domain of a fusogenic molecule (FM with the aim to improve targeted transduction of lentiviral vectors co-displaying an anti-CD20 antibody (αCD20 and a FM. Results Specific mutations were introduced into the fusion domain of a binding-deficient Sindbis virus glycoprotein to generate several mutant FMs. Lentiviral vectors incorporated with αCD20 and one of the engineered FMs were successfully produced and demonstrated to be able to preferentially deliver genes to CD-20-expressing cells. Lentiviral vectors bearing engineered FMs exhibited 8 to 17-fold enhanced transduction towards target cells as compared to the parental FM. Different levels of enhancement were observed for the different engineered FMs. A pH-dependent study of vector transduction showed that the broader pH range of the engineered FM is a possible mechanism for the resulted increase in transduction efficiency. Conclusion The fusion domain of Sindbis virus glycoprotein is amenable for engineering and the engineered proteins provide elevated capacity to mediate lentiviral vectors for targeted transduction. Our data suggests that application of such an engineering strategy can optimize the two-molecular targeting method of lentiviral vectors for gene delivery to predetermined cells.

    2007-06-01

    Nutritionists working in food manufacturing and retailing are potentially in a more powerful position than any other professional group to contribute towards achieving the national targets for nutrition and the reduction of nutrition-related diseases, set out in The Health of the Nation (DoH, 1992) and in Scotland's Health, A Challenge to Us All (Scottish Office, 1993). The present paper sets out the details of this argument. First, a review is given of the functions and types of activities carried out by nutritionists in industry. Then a number of key practical ways in which nutritionists, through their activities and functions, can help towards achieving national targets for nutrition and nutrition-related diseases are described. Finally, suggestions are made about the knowledge, skills, and personal attributes needed by nutritionists who intend making successful careers in industry and who wish, at the same time, to contribute towards improving the health of the nation.

    Current clinical anti-CD40 biologic agents include both antagonist molecules for the treatment of autoimmune diseases and agonist molecules for immuno-oncology, yet the relationship between CD40 epitope and these opposing biological outcomes is not well defined. This report describes the identification of potent antagonist domain antibodies (dAbs) that bind to a novel human CD40-specific epitope that is divergent in the CD40 of nonhuman primates. A similarly selected anti-cynomolgus CD40 dAb recognizing the homologous epitope is also a potent antagonist. Mutagenesis, biochemical, and X-ray crystallography studies demonstrate that the epitope is distinct from that of CD40 agonists. Both the human-specific and cynomolgus-specific molecules remain pure antagonists even when formatted as bivalent Fc-fusion proteins, making this an attractive therapeutic format for targeting hCD40 in autoimmune indications.

    Many papers have shown that bioenergy and land-use are potentially important elements in a strategy to limit anthropogenic climate change. But, significant expansion of bioenergy production can have a large terrestrial footprint. In this paper, we test the implications for land use, the global energy system, carbon cycle, and carbon prices of meeting a specific climate target, using a single fossil fuel and industrial sector policy instrument—the carbon tax, but with five alternative bioenergy and land-use policy architectures. We find that the policies we examined have differing effects on the different segments of the economy. Comprehensive land policies can reduce land-use change emissions, increasing allowable emissions in the energy system, but have implications for the cost of food. Bioenergy taxes and constraints, on the other hand, have little effect on food prices, but can result in increased carbon and energy prices.

  3. How much does it cost to achieve coverage targets for primary healthcare services? A costing model from Aceh, Indonesia.

    Abdullah, Asnawi; Hort, Krishna; Abidin, Azwar Zaenal; Amin, Fadilah M

    2012-01-01

    Despite significant investment in improving service infrastructure and training of staff, public primary healthcare services in low-income and middle-income countries tend to perform poorly in reaching coverage targets. One of the factors identified in Aceh, Indonesia was the lack of operational funds for service provision. The objective of this study was to develop a simple and transparent costing tool that enables health planners to calculate the unit costs of providing basic health services to estimate additional budgets required to deliver services in accordance with national targets. The tool was developed using a standard economic approach that linked the input activities to achieving six national priority programs at primary healthcare level: health promotion, sanitation and environment health, maternal and child health and family planning, nutrition, immunization and communicable diseases control, and treatment of common illness. Costing was focused on costs of delivery of the programs that need to be funded by local government budgets. The costing tool consisting of 16 linked Microsoft Excel worksheets was developed and tested in several districts enabled the calculation of the unit costs of delivering of the six national priority programs per coverage target of each program (such as unit costs of delivering of maternal and child health program per pregnant mother). This costing tool can be used by health planners to estimate additional money required to achieve a certain level of coverage of programs, and it can be adjusted for different costs and program delivery parameters in different settings.

  7. MODIFIED RELEASE FORMULATIONS TO ACHIEVE THE QUALITY TARGET PRODUCT PROFILE (QTPP

    Mithilesh Kumar Jha

    2012-08-01

    Full Text Available Modified Release (MR Formulations have a modification in the release mechanism. Modified release dosage forms are developed by altering drug absorption or the site of drug release in order to achieve predetermined clinical objectives. Modified drug release from dosage forms is complemented by the allied processes of drug design, of dosage administration, and of membrane transport and absorption of drug to the biological site of action. Modified-release drugs have complex formulations that can offer an advantage over standard medication for some patients. Modified-release preparations should only be used where there is a clear clinical advantage over conventional-release preparations. In general, Modified-release preparations should be reserved for specific patients where there is a problem with compliance, effectiveness or side-effects which these preparations could help overcome. Modified–release technologies have become indispensable to resolving critical technical, therapeutic, and marketing challenges, such as improving patience compliance, less dosage timings, better safety, better indications, delivering poorly soluble and poorly absorbable API’s, product differentiation, patent protection, product life-cycle extension, and better margins. Modified-release formulation design can be conducted for oral and non-oral administration routes. Possible therapeutic benefits of an MR product include improved efficacy and reduced adverse events, increased convenience and patient compliance, optimized performance, a greater selectivity of activity, or new indications.

  8. Achievement of Target Blood Pressure Levels among Japanese Workers with Hypertension and Healthy Lifestyle Characteristics Associated with Therapeutic Failure.

    Nagako Kudo

    Full Text Available Few studies have examined Japanese with regard to the achievement rates for target blood pressure levels, or the relationship between these rates and healthy lifestyle characteristics in patients with hypertension as defined by the newly established hypertension management guidelines (JSH2014. The aim of this study was to elucidate achievement rates and examine healthy lifestyle characteristics associated with achievement status among Japanese.This cross-sectional study, conducted in January-December 2012, examined blood pressure control and healthy lifestyle characteristics in 8,001 Japanese workers with hypertension (mean age, 57.0 years; 78.8% were men who participated in a workplace health checkup. Data were collected from workplace medical checkup records and participants' self-administered questionnaires. We divided into 5 groups [G1; young, middle-aged, and early-phase elderly patients (65-74 years old without diabetes mellitus or chronic kidney disease (CKD (<140/90 mmHg, G2; late-phase elderly patients (≥75 years old without diabetes mellitus or CKD (<150/90 mmHg, G3; diabetic patients (<130/80 mmHg, G4; patients with CKD (<130/80 mmHg, and G5; patients with cerebrovascular and/or coronary artery diseases (<140/90 mmHg] according to JSH2014. And then, achievement rates were calculated in each group. Multivariate analysis identified healthy lifestyle characteristics associated with "therapeutic failure" of target blood pressure.Target blood pressures were achieved by 60.2% of young, middle-aged, and early-phase elderly patients (G1, 71.4% of late-phase elderly patients (G2, 30.5% of diabetic patients (G3, 33.4% of those with chronic kidney disease (G4, and 66.0% of those with cerebrovascular and/or coronary artery diseases (G5. A body mass index of 18.5-24.9 and non-daily alcohol consumption were protective factors, and adequate sleep was found to contribute to therapeutic success.We found low achievement rates for treatment goals

  9. Physiological geroscience: targeting function to increase healthspan and achieve optimal longevity.

    Seals, Douglas R; Justice, Jamie N; LaRocca, Thomas J

    2016-04-15

    Most nations of the world are undergoing rapid and dramatic population ageing, which presents great socio-economic challenges, as well as opportunities, for individuals, families, governments and societies. The prevailing biomedical strategy for reducing the healthcare impact of population ageing has been 'compression of morbidity' and, more recently, to increase healthspan, both of which seek to extend the healthy period of life and delay the development of chronic diseases and disability until a brief period at the end of life. Indeed, a recently established field within biological ageing research, 'geroscience', is focused on healthspan extension. Superimposed on this background are new attitudes and demand for 'optimal longevity' - living long, but with good health and quality of life. A key obstacle to achieving optimal longevity is the progressive decline in physiological function that occurs with ageing, which causes functional limitations (e.g. reduced mobility) and increases the risk of chronic diseases, disability and mortality. Current efforts to increase healthspan centre on slowing the fundamental biological processes of ageing such as inflammation/oxidative stress, increased senescence, mitochondrial dysfunction, impaired proteostasis and reduced stress resistance. We propose that optimization of physiological function throughout the lifespan should be a major emphasis of any contemporary biomedical policy addressing global ageing. Effective strategies should delay, reduce in magnitude or abolish reductions in function with ageing (primary prevention) and/or improve function or slow further declines in older adults with already impaired function (secondary prevention). Healthy lifestyle practices featuring regular physical activity and ideal energy intake/diet composition represent first-line function-preserving strategies, with pharmacological agents, including existing and new pharmaceuticals and novel 'nutraceutical' compounds, serving as potential

  10. Mobile Health Insurance System and Associated Costs: A Cross-Sectional Survey of Primary Health Centers in Abuja, Nigeria

    Garg, Lalit; Eze, Godson

    2016-01-01

    Background Nigeria contributes only 2% to the world’s population, accounts for 10% of the global maternal death burden. Health care at primary health centers, the lowest level of public health care, is far below optimal in quality and grossly inadequate in coverage. Private primary health facilities attempt to fill this gap but at additional costs to the client. More than 65% Nigerians still pay out of pocket for health services. Meanwhile, the use of mobile phones and related services has risen geometrically in recent years in Nigeria, and their adoption into health care is an enterprise worth exploring. Objective The purpose of this study was to document costs associated with a mobile technology–supported, community-based health insurance scheme. Methods This analytic cross-sectional survey used a hybrid of mixed methods stakeholder interviews coupled with prototype throw-away software development to gather data from 50 public primary health facilities and 50 private primary care centers in Abuja, Nigeria. Data gathered documents costs relevant for a reliable and sustainable mobile-supported health insurance system. Clients and health workers were interviewed using structured questionnaires on services provided and cost of those services. Trained interviewers conducted the structured interviews, and 1 client and 1 health worker were interviewed per health facility. Clinic expenditure was analyzed to include personnel, fixed equipment, medical consumables, and operation costs. Key informant interviews included a midmanagement staff of a health-management organization, an officer-level staff member of a mobile network operator, and a mobile money agent. Results All the 200 respondents indicated willingness to use the proposed system. Differences in the cost of services between public and private facilities were analyzed at 95% confidence level (Pinformant interviews with a health management organizations and a telecom operator revealed high investment interests

  11. A Pharmacist-Staffed, Virtual Gout Management Clinic for Achieving Target Serum Uric Acid Levels: A Randomized Clinical Trial

    Goldfien, Robert; Pressman, Alice; Jacobson, Alice; Ng, Michele; Avins, Andrew

    2016-01-01

    Context: Relatively few patients with gout receive appropriate treatment. Objective: To determine whether a pharmacist-staffed gout management program is more effective than usual care in achieving target serum uric acid (sUA) levels in gout patients. Design: A parallel-group, randomized controlled trial of a pharmacist-staffed, telephone-based program for managing hyperuricemia vs usual care. Trial duration was 26 weeks. Main Outcome Measures: Primary outcome measure was achieving sUA levels at or below 6 mg/dL at the 26-week visit. Secondary outcome was mean change in sUA levels in the control and intervention groups. Participants were adults with recurrent gout and sUA levels above 6.0 mg/dL. Participants were randomly assigned to management by a clinical pharmacist following protocol or to monitoring of sUA levels but management of their gout by their usual treating physician. Results: Of 102 patients who met eligibility criteria, 77 subjects obtained a baseline sUA measurement and were entered into the trial. Among 37 participants in the intervention group, 13 (35%) had sUA levels at or below 6.0 mg/dL at 26 weeks, compared with 5 (13%) of 40 participants in the control group (risk ratio = 2.8, 95% confidence interval [CI] = 1.1 to 7.1, p = 0.03). The mean change in sUA levels among controls was +0.1 mg/dL compared with −1.5 mg/dL in the intervention group (sUA difference = −1.6, 95% CI = −0.9 to −2.4, p pharmacist-staffed program was more effective than usual care for achieving target sUA levels. These results suggest a structured program could greatly improve gout management. PMID:27352414

  13. Malaria in pregnancy; facts from the parasitology laboratory: a ten-year study in Abuja, North Central Nigeria

    Ibecheozor, N.K.O

    2014-09-01

    Full Text Available Malaria, which is transmitted by female Anopheles mosquitoes, is the major cause of mortality among the pregnant women in the sub-Saharan Africa. A ten year study of malaria in pregnancy was carried out in Abuja, North Central Nigeria. Thick and thin blood films were stained with the Giemsa methodology. Of the 16760 pregnant women blood samples, 4571 (27.3% were positive for malaria parasites caused by Plasmodium falciparum. Of the 4571 positive cases, 75 (1.7% had parasite density of >5000 parasites/µl of blood; 148 (3.2% had between 500-5000 parasites/µl of blood; 520 (11.4% had between 50 - 500 parasites/µl of blood; while 3828 (83.7% had between 5-50 parasites/µl of blood. With the current estimate of over 4500 deaths of pregnant women in Nigeria due to malaria annually, we must make deliberate efforts to stop these unacceptable and painful losses. The continued use of malaria rapid diagnostic tests (M-RDTs methodologies should be discontinued because of its negative implications. Therefore, the microscopic laboratory diagnostic component should be included in ANC at all level of health care facility.

  14. Detection of anti-Chlamydia trachomatis Antibodies in Patients with Acquired Immune Deficiency Syndrome in Abuja, Nigeria

    Izebe, K. S.

    2008-01-01

    Full Text Available Chlamydia trachomatis (CT infections are among the sexually transmitted diseases known to increase the risk for human immunodeficiency virus infection. Serum samples from 34 consenting AIDS patients which attended the Government-approved Antiretroviral Treatment (ART Facility at the National Institute for Pharmaceutical Research and Development (NIPRD, Abuja between April 2005 and March 2006 were screened by enzyme immunoassay (EIA for the presence of anti-CT antibodies using ImmunoComb® Chlamydia Bivalent IgG Test kit (Orgenics, Israel. Anti-CT antibodies were detected in ten (29.4% of the thirty-four patients tested. The detection rate was higher among the females (33.3% than the males (23.1%. Patients of the age group 31-45 years had the highest detection of anti-C. trachomatis antibodies, followed by those of age group 16-30 years. The result of the present study suggests the presence of anti-CT antibodies in AIDS patients, and reinforces the need for routine screening for anti-CT antibodies as a necessary intervention to reduce the burden of chlamydial diseases and to reduce the risk of HIV and its spread in Nigeria. The outcome of this study also provides justification for the possible inclusion of anti-chlamydial agents in the National AIDS Management Plan to treat associated C. trachomatis infections.

  15. Systematic Procedure for Generating Operational Policies to Achieve Target Crystal Size Distribution (CSD) in Batch Cooling Crystallization

    Abdul Samad, Noor Asma Fazli; Singh, Ravendra; Sin, Gürkan;

    Batch cooling crystallization is one of the important unit operations involving separation of solid-liquid phases. Usually the most common crystal product qualities are directly related to the crystal size distribution (CSD). However the main difficulty in batch crystallization is to obtain a...... uniform and reproducible CSD. Therefore supersaturation control can be applied to drive the process within the metastable zone and thereby enhance the control of the CSD. Although this approach has been shown to produce high quality crystals, the set point operating profiles for the supersaturation...... controller are usually chosen arbitrarily or by trial-and-error. Therefore there is a need for a systematic procedure to generate operational policy that guarantees the target CSD can be achieved. Furthermore, to predict the desired crystal morphology by means of model-based approaches, appropriate models...

  16. Implementation of energy-saving policies in China: How local governments assisted industrial enterprises in achieving energy-saving targets

    Local governments have replaced the national ministries that are in charge of various industries to become the primary implementer of energy-saving policies in China since 2000. This paper employs a case study-based approach to demonstrate the significance of local governments’ policy measures in assisting industrial enterprises with energy-saving activities in China. Based on the longitudinal case of the Jasmine Thermal Electric Power Company, this paper hypothesizes that sub-national governments have played a major role in implementing energy-saving policies in China since the 11th Five-year-plan period. A wide range of provincial and municipal agencies collaborated in implementing five types of policy measures – informational policy, skill building, improved enforcement of central directives, price adjustment, and funding – that reduced barriers to energy saving and motivated active pursuit of energy-saving activities at industrial enterprises. The case study demonstrates how an enterprise and local governments work together to achieve the enterprise's energy-saving target.

  17. Korea's emission trading scheme and policy design issues to achieve market-efficiency and abatement targets

    In 2008, the government of Republic of Korea (Korea) announced the national abatement target aiming at 30% reductions from the Business-as-Usual projections by 2020. Accordingly, the Emission Trading Scheme (ETS) will be implemented from 2015 onwards. As ETS performance substantially depends on the structural design, it is critically important to examine the details of Korean ETS for the achievement of cost effectiveness and concurrent development of an active emission trading market. This paper addresses several policy design issues for this purpose. After providing an overview on the current framework of Korean ETS, we propose ways to achieve flexibility, consistency and market efficiency of the program in consideration of the preexisting policies. Issues in policy design are discussed by focusing on allowance allocation, market stabilization measures and price mechanism in the emission and energy markets in Korea. This paper will serve as a practical guideline for establishing sustainable and market-efficient Korean ETS that can be compatible with the international standards as in the EU ETS. - Highlights: • Emission Trading Scheme (ETS) will be implemented from 2015 in Korea to reduce CO2. • ETS performance substantially depends on structural design. • We provide policy overview on the current framework of Korean ETS. • Several policy design issues are discussed for developing policy consistency. • We focus on allowance allocation, allowance reserve and market stabilization measures

  19. Can we bet on negative emissions to achieve the 2°C target even under strong carbon cycle feedbacks?

    Tanaka, K.; Yamagata, Y.; Yokohata, T.; Emori, S.; Hanaoka, T.

    2015-12-01

    tentative results point to a key policy message: do not rely on negative emissions to achieve the 2°C target. It would make more sense to gear climate mitigation actions toward the stabilization target without betting on negative emissions because negative emissions might create large overshoot in case of strong feedbacks.

    2014-04-01

    Bwari is one of the six municipal area councils of the Federal Capital Territory (FCT), Abuja with its attendant growing population and infrastructural developments. Groundwater is the main source of water supply in the area, and urbanization and industrialization are the predominant contributors of contaminants to the hydrological systems. In order to guarantee a continuous supply of potable water, there is a need to investigate the vulnerability of the aquifers to contaminants emanating from domestic and industrial wastes. A total of 20 vertical electrical soundings using Schlumberger electrode array with a maximum half current electrodes separation of 300 m was employed. The results show that the area is characterized by 3–6 geoelectric subsurface layers. The measured overburden thickness ranges from 1.0 to 24.3 m, with a mean value of 7.4 m. The resistivity and longitudinal conductance of the overburden units range from 18 to 11,908 m and 0.047 to 0.875 mhos, respectively. Areas considered as high corrosivity are the central parts with > 180 m. The characteristic longitudinal unit conductance was used to classify the area into zones of good (0.7–4.49 mhos), moderate (0.2–0.69 mhos), weak (0.1–0.19 mhos), and poor (> 0.1) aquifer protective capacity. Zones characterized by materials of moderate to good protective capacity serve as sealing potential for the underlying hydrogeological system in the area. This study is aimed at delineating zones that are very prone to groundwater contamination from surface contaminants and subsurface soils that are corrosive to utility pipes buried underground. Hence the findings of this work will constitute part of the tools for groundwater development and management and structural/infrastructural development planning of the area.

  1. Measurement of 238U, 232Th and 40K in boreholes at Gosa and Lugbe, Abuja, north central Nigeria

    The purpose of this project is to evaluate the suitability of different sites as locations for obtaining underground water for consumption. The analysis of 238U, 232Th and 40K from rock samples from each layer of borehole at a depth of ∼50 m at Site A borehole, S3L1-S3L6 in Gosa and 40 m at Site B borehole, S4L1-S4L5 in Lugbe, Abuja, north central Nigeria is presented. The gamma-ray spectrometry was carried out using a high-purity germanium detector coupled to a computer-based high-resolution multichannel analyzer. The activity concentrations at Site A borehole for 238U have a mean value of 26±3, ranging from 23±2 to 30±3 Bq kg-1, 232Th a mean value of 63±5, ranging from 48±4 to 76±6 Bq kg-1 and 40K a mean value of 573±72, ranging from 437±56 to 821±60 Bq kg-1. The activity concentrations at Site B borehole for 238U have a mean value of 20±2, ranging from 16±2 to 23±2 Bq kg-1, 232Th a mean value of 46±4, ranging from 43±4 to 49±4 Bq kg-1, 40K a mean value of 915±116 and ranging from 817±103 Bq kg-1 to 1011±128 Bq kg-1. It is noted that the higher activity concentrations of 232Th and 238U are found in Site A at Gosa. Site B has lower radioactivity, and it is recommended that both sites are suitable for underground water consumption. (authors)

    2014-08-27

    The poor permeability of glioma parenchyma represents a major limit for antiglioblastoma drug delivery. Gracilaria lemaneiformis polysaccharide (GLP), which has a high binding affinity to αvβ3 integrin overexpressed in glioma cells, was employed in the present study to functionalize selenium nanoparticles (SeNPs) to achieve antiglioblastoma efficacy. GLP-SeNPs showed satisfactory size distribution, high stability, and selectivity between cancer and normal cells. In U87 glioma cell membrane, which has a high integrin expression level, GLP-SeNPs exhibited significantly higher cellular uptake than unmodified SeNPs. As expected, U87 cells exhibited a greater uptake of GLP-SeNPs than C6 cells with low integrin expression level. Furthermore, the internalization of GLP-SeNPs was inhibited by cyclo-(Arg-Gly-Asp-Phe-Lys) peptides, suggesting that cellular uptake into U87 cells and C6 cells occurred via αvβ3 integrin-mediated endocytosis. For U87 cells, the cytotoxicity of SeNPs decorated by GLP was enhanced significantly because of the induction of various apoptosis signaling pathways. Internalized GLP-SeNPs triggered intracellular reactive oxygen species downregulation. Therefore, p53, MAPKs, and AKT pathways were activated to advance cell apoptosis. These findings suggest that surface decoration of nanomaterials with GLP could be an efficient strategy for design and preparation of glioblastoma targeting nanodrugs. PMID:25073123

  3. Framework for the analysis of the low-carbon scenario 2020 to achieve the national carbon Emissions reduction target: Focused on educational facilities

    Since the increase in greenhouse gas emissions has increased the global warming potential, an international agreement on carbon emissions reduction target (CERT) has been formulated in Kyoto Protocol (1997). This study aimed to develop a framework for the analysis of the low-carbon scenario 2020 to achieve the national CERT. To verify the feasibility of the proposed framework, educational facilities were used for a case study. This study was conducted in six steps: (i) selection of the target school; (ii) establishment of the reference model for the target school; (iii) energy consumption pattern analysis by target school; (iv) establishment of the energy retrofit model for the target school; (v) economic and environmental assessment through the life cycle cost and life cycle CO2 analysis; and (vi) establishment of the low-carbon scenario in 2020 to achieve the national CERT. This study can help facility managers or policymakers establish the optimal retrofit strategy within the limited budget from a short-term perspective and the low-carbon scenario 2020 to achieve the national CERT from the long-term perspective. The proposed framework could be also applied to any other building type or country in the global environment

    Full Text Available This study analyzed the spatiotemporal pattern of settlement expansion in Abuja, Nigeria, one of West Africa’s fastest developing cities, using geoinformation and ancillary datasets. Three epochs of Land-use Land-cover (LULC maps for 1986, 2001 and 2014 were derived from Landsat images using support vector machines (SVM. Accuracy assessment (AA of the LULC maps based on the pixel count resulted in overall accuracy of 82%, 92% and 92%, while the AA derived from the error adjusted area (EAA method stood at 69%, 91% and 91% for 1986, 2001 and 2014, respectively. Two major techniques for detecting changes in the LULC epochs involved the use of binary maps as well as a post-classification comparison approach. Quantitative spatiotemporal analysis was conducted to detect LULC changes with specific focus on the settlement development pattern of Abuja, the federal capital city (FCC of Nigeria. Logical transitions to the urban category were modelled for predicting future scenarios for the year 2050 using the embedded land change modeler (LCM in the IDRISI package. Based on the EAA, the result showed that urban areas increased by more than 11% between 1986 and 2001. In contrast, this value rose to 17% between 2001 and 2014. The LCM model projected LULC changes that showed a growing trend in settlement expansion, which might take over allotted spaces for green areas and agricultural land if stringent development policies and enforcement measures are not implemented. In conclusion, integrating geospatial technologies with ancillary datasets offered improved understanding of how urbanization processes such as increased imperviousness of such a magnitude could influence the urban microclimate through the alteration of natural land surface temperature. Urban expansion could also lead to increased surface runoff as well as changes in drainage geography leading to urban floods.

  8. The central importance of the EU emission trading scheme for achievement of the German climate protection target of 40% until 2020

    Both Germany and the European Union have set themselves targets for the reduction of greenhouse gas (GHG) emissions. The EU was the forerunner in 2008 when it adopted the Climate and Energy package and set a target of reducing GHG emissions by 20 % by 2020 compared to 1990. Two years later, Germany adopted a range of national GHG targets in the context of the German government's Energy Concept. This includes a 40% emissions reduction target to be met by 2020. One of the main instruments for achieving GHG emissions reduction targets is the EU Emissions Trading Scheme (EU ETS), which covers all large industrial and combustion installations in Europe. According to the agreement made in 2008 (Climate and Energy Package), the effort to achieve the EU's 20 % reduction target by 2020 was split between the ETS sector (2/3 of the reduction effort, representing a 21 % reduction in GHG emissions for installations covered under the ETS compared to 2005) and the non-ETS sector (1/3 of the reduction effort, representing a 10 % reduction compared to 2005). Logically, GHG emissions reductions occurring in German ETS installations count both towards the EU and the national target. This research project has been commissioned to analyse whether the ETS in its cur-rent design can contribute its fair share in efforts to meet the national emissions reduc-tion target. This question is particularly relevant in light of the following considerations: - The new German Coalition Agreement, signed in December 2013, reiterated the national target of a 40 % reduction of GHG emissions by 2020 compared to 1990 levels. - At the same time, the new Coalition Agreement stated that changes to the ETS are only to be considered if the EU GHG emissions reduction target will not be met. - There is a surplus of CO2 allowances on the ETS market, which undermines the credibility of the instrument as well as the integrity of the emissions reduction tar-gets (both European and national). At the same time, the

  9. The evolution of flexibility mechanisms for achieving European renewable energy targets 2020-ex-ante evaluation of the principle mechanisms

    In December 2008, the European Council and the European Parliament agreed on a final compromise for a new European renewable energy directive. One of the most debated issues prior to this compromise was the design of 'target flexibility mechanisms', which should allow member states with low or expensive renewable energy potential to partly fulfil their national renewable energy target in other countries. This article traces back the political discussion that has led to the evolution of the different flexibility options. It then evaluates the most prominent flexibility mechanisms against a set of qualitative criteria. It concludes that free or restricted certificate trade based on guarantees of origin (GOs) - as proposed earlier by the European Commission - is not a viable option due to some 'knockout' criteria, despite other potential advantages. The mechanisms that have replaced GO trade in the final compromise - joint projects, joint support schemes and statistical transfer between member states - provide less flexibility, but score better against a number of other important criteria. The crucial question for the coming years is how their utilisation can be facilitated. One first step might be that proactive member states define open design issues for implementing the mechanisms.

  11. Achieving California's 80% greenhouse gas reduction target in 2050: Technology, policy and scenario analysis using CA-TIMES energy economic systems model

    The CA-TIMES optimization model of the California Energy System (v1.5) is used to understand how California can meet the 2050 targets for greenhouse gas (GHG) emissions (80% below 1990 levels). This model represents energy supply and demand sectors in California and simulates the technology and resource requirements needed to meet projected energy service demands. The model includes assumptions on policy constraints, as well as technology and resource costs and availability. Multiple scenarios are developed to analyze the changes and investments in low-carbon electricity generation, alternative fuels and advanced vehicles in transportation, resource utilization, and efficiency improvements across many sectors. Results show that major energy transformations are needed but that achieving the 80% reduction goal for California is possible at reasonable average carbon reduction cost ($9 to $124/tonne CO2e at 4% discount rate) relative to a baseline scenario. Availability of low-carbon resources such as nuclear power, carbon capture and sequestration (CCS), biofuels, wind and solar generation, and demand reduction all serve to lower the mitigation costs, but CCS is a key technology for achieving the lowest mitigation costs. - Highlights: • We model the California Energy System to 2050 under policy and technology scenarios. • The model optimizes technology and resource investments to meet emissions targets. • Deep emissions cuts (>74%) are achieved across all reduction scenarios. • Carbon capture enables negative emission biofuels and allows more petroleum use. • Greenhouse gas mitigation cost is small compared with total economic activity

  13. Coated minispheres of salmon calcitonin target rat intestinal regions to achieve systemic bioavailability: Comparison between intestinal instillation and oral gavage.

    Aguirre, Tanira A S; Aversa, Vincenzo; Rosa, Mónica; Guterres, Sílvia S; Pohlmann, Adriana R; Coulter, Ivan; Brayden, David J

    2016-09-28

    Achieving oral peptide delivery is an elusive challenge. Emulsion-based minispheres of salmon calcitonin (sCT) were synthesized using single multiple pill (SmPill®) technology incorporating the permeation enhancers (PEs): sodium taurodeoxycholate (NaTDC), sodium caprate (C10), or coco-glucoside (CG), or the pH acidifier, citric acid (CA). Minispheres were coated with an outer layer of Eudragit® L30 D-55 (designed for jejunal release) or Surelease®/Pectin (designed for colonic release). The process was mild and in vitro biological activity of sCT was retained upon release from minispheres stored up to 4months. In vitro release profiles suggested that sCT was released from minispheres by diffusion through coatings due to swelling of gelatin and the polymeric matrix upon contact with PBS at pH6.8. X-ray analysis confirmed that coated minispheres dissolved at the intended intestinal region of rats following oral gavage. Uncoated minispheres at a dose of ~2000I.U.sCT/kg were administered to rats by intra-jejunal (i.j.) or intra-colonic (i.c.) instillation and caused hypocalcaemia. Notable sCT absolute bioavailability (F) values were: 5.5% from minispheres containing NaTDC (i.j), 17.3% with CG (i.c.) and 18.2% with C10 (i.c.). Coated minispheres administered by oral gavage at threefold higher doses also induced hypocalcaemia. A highly competitive F value of 2.7% was obtained for orally-administered sCT-minispheres containing CG (45μmol/kg) and coated with Eudragit®. In conclusion, the SmPill® technology is a potential dosage form for several peptides when formulated with PEs and coated for regional delivery. PK data from instillations over-estimates oral bioavailability and poorly predicts rank ordering of formulations. PMID:27480451

    Tao, L.; Schell, D.; Davis, R.; Tan, E.; Elander, R.; Bratis, A.

    2014-04-01

    For the DOE Bioenergy Technologies Office, the annual State of Technology (SOT) assessment is an essential activity for quantifying the benefits of biochemical platform research. This assessment has historically allowed the impact of research progress achieved through targeted Bioenergy Technologies Office funding to be quantified in terms of economic improvements within the context of a fully integrated cellulosic ethanol production process. As such, progress toward the ultimate 2012 goal of demonstrating cost-competitive cellulosic ethanol technology can be tracked. With an assumed feedstock cost for corn stover of $58.50/ton this target has historically been set at $1.41/gal ethanol for conversion costs only (exclusive of feedstock) and $2.15/gal total production cost (inclusive of feedstock) or minimum ethanol selling price (MESP). This year, fully integrated cellulosic ethanol production data generated by National Renewable Energy Laboratory (NREL) researchers in their Integrated Biorefinery Research Facility (IBRF) successfully demonstrated performance commensurate with both the FY 2012 SOT MESP target of $2.15/gal (2007$, $58.50/ton feedstock cost) and the conversion target of $1.41/gal through core research and process improvements in pretreatment, enzymatic hydrolysis, and fermentation.

    Bachiller Araque, J.

    2010-07-01

    The European Union and the energy sector should particularly face up to the triple challenge of increasing the security of supply, de carbonizing its production system and improving the competitiveness of its business network. Achieving the above objectives will involve relevant changes in the way to satisfy the primary energy demand and the electricity generation mix, the development and incorporation of new technologies, as well as the full completion of the internal energy market. Moreover, achieving the 20 targets in 2020 and perhaps a greater requirement on one of them will require increased energy efficiency in the whole chain, from production to consumption, as well as policies and initiatives on energy saving which are consistent with the maintenance of the current levels of welfare.

    Full Text Available This study examined Probit model analysis of smallholder’s farmers decision to use agrochemical inputs in Gwagwalada and Kuje Area Councils of Federal Capital Territory, Abuja, Nigeria. Primary data were used for this study. Data were obtained using structured questionnaire. The questionnaires were administered to sixty smallholder’s farmers sampled using a two-stage sampling technique. Data obtained were analyzed using descriptive statistics and Probit model. Eight estimators, age; farm-size; education–level; extension services; access to credit; off-farm income; experiences in farming; in the Probit model were found statistically significant. Results show that the probability of using agrochemical inputs increases with age; farm-size; family-size; education-level; extension services; experiences in farming but decreases where they have off-farm income and access to credits. Mc Fadden Pseudo-R 2 gives 0.6866 and Probit model correctly classified 93%. This study concluded that capacity of agricultural extension agents needs to be improved in the study area to educate farmers to invest in agrochemicals and improved agricultural technologies. Also, Government needs to improve on good road networks and appropriate policies to regulate standard, use, safety needs and environment of use of agrochemicals in the study area.

  17. Tectonic and radioactivity impacts of 238U on groundwater-based drinking water at Gosa and Lugbe areas of Abuja, North Central Nigeria

    Tectonic contribution of activity level of 238U in groundwater-based drinking water in Gosa and Lugbe areas of Abuja was measured using inductively coupled plasma mass spectrometry (ICP-MS). The highest activity level of 2736 µBq L-1 reported in Lugbe borehole, whereas the lowest value of 443 µBq L-1 reported at Gosa borehole. The inhabitants permanently used water from the boreholes for daily consumption. The group receives 5.55 × 10-5 mSv of the annual collective effective dose due to 238U in drinking water. The radiological risks of 238U in the water samples were found to be low, typically in magnitude of 10-7 with cancer mortality value of 1.03 × 10-7 and morbidity value of 1.57 × 10-7. The chemical toxicity risk of 238U in drinking water over a lifetime consumption has a mean value of 4.0 × 10-3 μg kg-1 day-1. It could be that the human risk due to 238U content in groundwater supplies from ingestion may likely be the chemical toxicity of 238U as a heavy metal rather than radiological risk. Significantly, Lugbe subsurface may have developed some fractions of granitic strata that contributed to the distribution of radioactive of 238U in tectonically weak zones. (author)

  19. Achieving stringent climate targets. An analysis of the role of transport and variable renewable energies using energy-economy-climate models

    Pietzcker, Robert Carl

    2014-07-01

    Anthropogenic climate change is threatening the welfare of mankind. Accordingly, policy makers have repeatedly stated the goal of slowing climate change and limiting the increase of global mean temperature to less than 2 C above pre-industrial times (the so-called ''two degree target''). Stabilizing the temperature requires drastic reductions of greenhouse gas (GHG) emissions to nearly zero. As the global system of energy supply currently relies on fossil fuels, reducing GHG emissions can only be achieved through a full-scale transformation of the energy system. This thesis investigates the economic requirements and implications of different scenarios that achieve stringent climate mitigation targets. It starts with the analysis of characteristic decarbonization patterns and identifies two particularly relevant aspects of mitigation scenarios: deployment of variable renewable energies (VRE) and decarbonization of the transport sector. After investigating these fields in detail, we turned towards one of the most relevant questions for policy makers and analyzed the trade-off between the stringency of a climate target and its economic requirements and implications. All analyses are based on the improvement, application, comparison, and discussion of large-scale IAMs. The novel ''mitigation share'' metric allowed us to identify the relevance of specific technology groups for mitigation and to improve our understanding of the decarbonization patterns of different energy subsectors. It turned out that the power sector is decarbonized first and reaches lowest emissions, while the transport sector is slowest to decarbonize. For the power sector, non-biomass renewable energies contribute most to emission reductions, while the transport sector strongly relies on liquid fuels and therefore requires biomass in combination with carbon capture and sequestration (CCS) to reduce emissions.

    Anthropogenic climate change is threatening the welfare of mankind. Accordingly, policy makers have repeatedly stated the goal of slowing climate change and limiting the increase of global mean temperature to less than 2 C above pre-industrial times (the so-called ''two degree target''). Stabilizing the temperature requires drastic reductions of greenhouse gas (GHG) emissions to nearly zero. As the global system of energy supply currently relies on fossil fuels, reducing GHG emissions can only be achieved through a full-scale transformation of the energy system. This thesis investigates the economic requirements and implications of different scenarios that achieve stringent climate mitigation targets. It starts with the analysis of characteristic decarbonization patterns and identifies two particularly relevant aspects of mitigation scenarios: deployment of variable renewable energies (VRE) and decarbonization of the transport sector. After investigating these fields in detail, we turned towards one of the most relevant questions for policy makers and analyzed the trade-off between the stringency of a climate target and its economic requirements and implications. All analyses are based on the improvement, application, comparison, and discussion of large-scale IAMs. The novel ''mitigation share'' metric allowed us to identify the relevance of specific technology groups for mitigation and to improve our understanding of the decarbonization patterns of different energy subsectors. It turned out that the power sector is decarbonized first and reaches lowest emissions, while the transport sector is slowest to decarbonize. For the power sector, non-biomass renewable energies contribute most to emission reductions, while the transport sector strongly relies on liquid fuels and therefore requires biomass in combination with carbon capture and sequestration (CCS) to reduce emissions.

  2. Split vector systems for ultra-targeted gene delivery: a contrivance to achieve ethical assurance of somatic gene therapy in vivo.

    Tolmachov, Oleg E

    2014-08-01

    Tightly controlled spatial localisation of therapeutic gene delivery is essential to maximize the benefits of somatic gene therapy in vivo and to reduce its undesired effects on the 'bystander' cell populations, most importantly germline cells. Indeed, complete ethical assurance of somatic gene therapy can only be achieved with ultra-targeted gene delivery, which excludes the risk of inadvertent germline gene transfer. Thus, it is desired to supplement existing strategies of physical focusing and biological (cell-specific) targeting of gene delivery with an additional principle for the rigid control over spread of gene transfer within the body. In this paper I advance the concept of 'combinatorial' targeting of therapeutic gene transfer in vivo. I hypothesize that it is possible to engineer complex gene delivery vector systems consisting of several components, each one of them capable of independent spread within the human body but incapable of independent facilitation of gene transfer. As the gene delivery augmented by such split vector systems would be reliant on the simultaneous availability of all the vector system components at a predetermined body site, it is envisaged that higher order reaction kinetics required for the assembly of the functional gene transfer configuration would sharpen spatial localisation of gene transfer via curtailing the blurring effect of the vector spread within the body. A particular implementation of such split vector system could be obtained through supplementing a viral therapeutic gene vector with a separate auxiliary vector carrying a non-integrative and non-replicative form of a gene (e.g., mRNA) coding for a cellular receptor of the therapeutic vector component. Gene-transfer-enabling components of the vector system, which would be delivered separately from the vector component loaded with the therapeutic gene cargo, could also be cell-membrane-insertion-proficient receptors, elements of artificial transmembrane channels

    Knowledge regarding antimicrobial therapy strategies in deep sternal wound infections (DSWI) following cardiac surgery is limited. Therefore, we aimed to determine the steady-state plasma and mediastinal concentrations of oxacillin administered by continuous infusion in critically ill patients with DSWI and to compare these concentrations with the susceptibility of staphylococci recovered. A continuous infusion of oxacillin (150 to 200 mg/kg of body weight/24 h) was administered after a loading dose (50 mg/kg). Plasma and mediastinal concentrations of total and unbound oxacillin were determined 4 h after the loading dose (H4) and then at day 1 (H24) and day 2 (H48). Twelve patients were included. Nine patients exhibited bacteremia, 5 were in septic shock, 8 were positive for Staphylococcus aureus, and 4 were positive for coagulase-negative staphylococci. The median MIC (first to third interquartile range) was 0.25 (0.24 to 0.41) mg/liter. Median plasma concentrations of total and unbound oxacillin at H4, H24, and H48 were, respectively, 64.4 (41.4 to 78.5) and 20.4 (12.4 to 30.4) mg/liter, 56.9 (31.4 to 80.6) and 21.7 (6.5 to 27.3) mg/liter, and 57.5 (32.2 to 85.1) and 20 (14.3 to 35.7) mg/liter. The median mediastinal concentrations of total and unbound oxacillin at H4, H24, and H48 were, respectively, 2.3 (0.7 to 25.9) and 0.9 (oxacillin delivered by continuous infusion is a valuable strategy to achieve our pharmacokinetic target (4× MIC) at the site of action at H24. But concerns remain in cases of higher MICs, emphasizing the need for clinicians to obtain the MICs for the bacteria and to monitor oxacillin concentrations, especially the unbound forms, at the target site.

  4. Radioactivity level and toxic elemental concentration in groundwater at Dei-Dei and Kubwa areas of Abuja, north-central Nigeria

    The activity concentrations of uranium and toxic elements in Dei-Dei borehole, Kubwa borehole, Water Board and hand-dug well water samples in Abuja area were measured using inductively coupled plasma mass spectrometry (ICP-MS) system. The results obtained were used to calculate human radiological risk over lifetime consumption by the inhabitants in the area. The activity concentrations of 238U in all the water supplies for drinking ranges from 0.849 mBq L−1 to 2.699 mBq L−1 with the highest value of 2.699 mBq L−1 noted at Dei-Dei borehole whereas the lowest value of 0.849 mBq L−1 was noted in Kubwa borehole. The highest annual effective dose from natural 238U in all the water samples was found in Dei-Dei borehole with a value of 8.9×10−5 mSv y−1 whereas the lowest value was noted in Kubwa borehole with a value of 2.8×10−5 mSv y−1. The radiological risks for cancer mortality were found distinctly low, with the highest value of 1.01×10−7 reported at Dei-Dei borehole compared to Kubwa borehole with a value of 3.01×10−8. The cancer morbidity risk was noted higher in Dei-Dei borehole with a value of 1.55×10−7 whereas lower value of 4.88×10−9 was reported in Kubwa borehole. The chemical toxicity risk of 238U in drinking water over a lifetime consumption has a value of 0.006 μg kg−1 day−1 in Dei-Dei borehole whereas lower value of 0.002 μg kg−1 day−1 was found in Kubwa borehole. Measured lead (Pb) and chromium (Cr) concentrations reported higher in Water Board compared to Dei-Dei and Kubwa borehole samples. Significantly, this study inferred that the 238U concentrations originate from granitic strata of the tectonic events in the area; thus, there was a trend of diffusion towards north to south and re-deposition towards Dei-Dei area. - Highlights: • The estimation of human radiological risk over lifetime consumption. • Determination of radiological risks. • The annual effective dose of 238U in drinking water. • Carcinogenic

    Facing the mounting pressure on energy security and increasing environmental concerns about air pollution and climate change, the Chinese government set a mandatory goal of 20% reduction of energy intensity in its 11th Five-Year Plan period (FYP, 2006-2010). In this paper we use Shanxi province to illustrate how policies and measures are implemented in practice at a provincial level as a response to the National FYP issued by the central government. Local policies are described and their effects are analyzed. We compare reported energy saving achievements with our own estimates and conclude that the achievements in Shanxi probably have been substantial since the start of the 11th FYP period. The most important measures taken by provincial and local governments seem to be in the secondary sector, such as Top-200/Top-1000 program and phasing out outdated technologies. However, Shanxi has still a long way to go to achieve satisfactory energy use. Further improvement of energy intensity will require continuing efforts. Although many measures are necessary, improving the energy efficiency in heavy industries and reducing the dependence on these industries should be particularly effective. - Highlights: > We use Shanxi province to illustrate how local policies respond to the National FYP. > Energy saving in Shanxi has been substantial since the start of the 11th FYP. > Assumptions about baseline energy use strongly affects energy saving estimates. > The most important measures taken by local governments are in the secondary sector. > Further improvement of energy intensity will require efforts especially in heavy industries.

  7. The central importance of the EU emission trading scheme for achievement of the German climate protection target of 40% until 2020; Die zentrale Bedeutung des EU-Emissionshandels zur Erreichung des deutschen Klimaziels in Hoehe von 40 % bis 2020

    Hermann, Hauke; Cludius, Johanna

    2014-02-15

    Both Germany and the European Union have set themselves targets for the reduction of greenhouse gas (GHG) emissions. The EU was the forerunner in 2008 when it adopted the Climate and Energy package and set a target of reducing GHG emissions by 20 % by 2020 compared to 1990. Two years later, Germany adopted a range of national GHG targets in the context of the German government's Energy Concept. This includes a 40% emissions reduction target to be met by 2020. One of the main instruments for achieving GHG emissions reduction targets is the EU Emissions Trading Scheme (EU ETS), which covers all large industrial and combustion installations in Europe. According to the agreement made in 2008 (Climate and Energy Package), the effort to achieve the EU's 20 % reduction target by 2020 was split between the ETS sector (2/3 of the reduction effort, representing a 21 % reduction in GHG emissions for installations covered under the ETS compared to 2005) and the non-ETS sector (1/3 of the reduction effort, representing a 10 % reduction compared to 2005). Logically, GHG emissions reductions occurring in German ETS installations count both towards the EU and the national target. This research project has been commissioned to analyse whether the ETS in its cur-rent design can contribute its fair share in efforts to meet the national emissions reduc-tion target. This question is particularly relevant in light of the following considerations: - The new German Coalition Agreement, signed in December 2013, reiterated the national target of a 40 % reduction of GHG emissions by 2020 compared to 1990 levels. - At the same time, the new Coalition Agreement stated that changes to the ETS are only to be considered if the EU GHG emissions reduction target will not be met. - There is a surplus of CO2 allowances on the ETS market, which undermines the credibility of the instrument as well as the integrity of the emissions reduction tar-gets (both European and national).

    In this scenario, the analysis shows how international climate change agreements and the population's attitude to climate-friendly actions could affect Norway's ability to achieve the objectives of national emission reductions. Political feasibility, technology and carbon price may vary according to how forces will move in future. Some measures to reduce greenhouse gas emissions may be more robust against future uncertainties than others. Scenario analysis can therefore provide useful perspectives when instruments should be implemented to reduce greenhouse gas emissions in the years ahead. (AG)

Multiple methods, including transmission electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis, bicinchoninic acid assay, and nitrogen adsorption and desorption isotherms, were used to characterize the tHMSN. Doxorubicin were chosen as the model cargo, and the uptake of doxorubicin-loaded tHMSN into MDA-MB-231 cells and human umbilical vein endothelial cells (HUVECs, as models of tumor cells and tumor neovascular endothelial cells, respectively, were observed and detected by confocal laser scanning microscopy and flow cytometry. An in vitro pharmacodynamic study and a study of the mechanism via which the nanoparticles were endocytosed were also performed.Results: HMSN with a highly uniform size and well oriented mesopores were synthesized. After tHMSN were characterized, enhanced uptake of the cargo carried by tHMSN into MDA-MB-231 cells and HUVECs compared with that of their unmodified counterparts was validated by confocal laser scanning microscopy and flow cytometry at the qualitative and quantitative levels, respectively. Further, the pharmacodynamic study suggested that, compared with their unmodified counterparts, doxorubicin-loaded tHMSN had an enhanced inhibitory effect on MDA-MB-231 cells and HUVECs in vitro.

    There are national targets for salt intake of 6 g salt/day in Australia and the United States. Despite this, there is limited knowledge about the effectiveness of dietary education in reducing salt intake to this level. The objective of this study was to investigate whether dietary education enabled a reduction in salt consumption. In an 8-week parallel study, 49 healthy free-living adults were recruited from the Adelaide community by newspaper advertisement. In a randomized parallel design, participants received dietary education to choose foods identified by either Australia's National Heart Foundation Tick symbol or by the Food Standards Australia and New Zealand's low-salt guideline of 120 mg sodium/100 g food. Sodium excretion was assessed by 24-hour urinary sodium collections at baseline and weeks 4 and 8. Participants' experiences of following the education strategies were recorded by self-administered questionnaire. These data were collected between August and October 2008. Forty-three participants completed the study. After 8 weeks, urinary sodium excretion decreased from 121+/-50 to 106+/-47 mmol/24 hours (7.3+/-3.0 to 6.4+/-2.8 g salt/24 hours) in the Tick group and from 132+/-44 to 98+/-50 mmol/24 hours (7.9+/-2.6 to 6.0+/-3.0 g salt/24 hours) in the Food Standards Australia New Zealand group (Pfood choice, difficulty when eating out, and increased time associated with identifying foods.

  20. Environmental impact of elemental concentration and distribution in waters, soils and plants along the Lokoja-Abuja pipeline routes of Bida Basin, northwestern Nigeria

    Boboye, Olugbenga A.; Abumere, Iyior O.

    2014-11-01

    This paper presents environmental study carried out to evaluate the impacts of elements' concentrations in water, soil, plants and the level of environmental damage. This is to establish the rate of pollution and degree of enrichment to enhance delineation of highly polluted areas along the pipeline routes. It was achieved by determining their spatial distribution, concentration and/or occurrences as well as the possible sources of enrichment. Forty-six (46) surface water samples were collected during the dry season while thirty (30) surface water samples were collected in the wet season respectively. The sampling was systematically carried out at diverse locations along the streams and major rivers to broadly cover the variation in the area. Fifty-one (51) soil samples were collected during dry and wet seasons to determine the texture, heavy metal concentration and physico-chemical characteristics. Thirty (30) and twenty-six (26) samples of stream and river sediments were also collected during the dry and wet seasons for physico-chemical characterization, texture and heavy metal concentrations. Ten plant tissues were collected and analysed to ascertain the rate of absorption. The results of the surface water during the dry and wet seasons showed slight acidity while the Electrical Conductivity revealed that the major ions are higher in the dry season. The major anions and cations accounted for about 71% and 29% of the Total Dissolved Solids respectively. The higher concentrations of Fe in the stream sediments and soil than that in the water and plant tissues suggest the weathering of oolitic, pisolitic and argillaceous ironstone within the area. Concentration of NH4 emanate from anthropogenic sources Textural classification revealed sand dominated soil which confirmed that the soil and stream sediment are autochthonous. The concentration of heavy metals and cations for both seasons in the plant tissues showed no discrepancy. The hydro-chemical facies

  2. Indonesian Achievement [Country report: Indonesia

    Since 1996 Indonesia has produced 99Mo from HEU fission product mainly for domestic consumption. Due to limited and restricted raw material of HEU, Indonesia has a conversion program from HEU to LEU for producing 99Mo from LEU foil target. The substitution of low enriched uranium (LEU) metal foils for the HEU UO2 used in current target designs will be applied for production of 99Mo commercially. Batan has had a joint research project with ANL to develop LEU-metal-foil target fabrication since 1992. Many achievements have resulted from the experiments. Design target has undergone several changes in design, materials and wrapping of LEU foil targets. ANL has developed several of LEU target design and fabrication, and has demonstrated Radio Metallurgy Installation hot cell in Batan for disassembly process to take out LEU foil from the target after being irradiated in the RSG-GAS BATAN reactor. Installed power of RSG-GAS is 30 MW but operational power is 15 MW. LEU foil targets were irradiated in CIP of RSG-GAS with thermal neutron flux 2.4x1014n cm-2s-1. Chemical processing was conducted in Isotope Production Centre hot cell for producing 99Mo which will be used to produce 99mTc generator. Batan has a license to use the process from US DOE. The experiment was terminated temporarily in 2001 due to September eleven accident. In 2004, cooperation between the ANL and BATAN was continued. In November 2005, ANL provided training on LEU target assembly to BATAN by simulation of Cu-foil as LEU foil. Then BATAN personnel demonstrated reassembly of 2 ANL LEU targets to replace Zn and Al foil barrier with Ni foil barrier in January 2006. In 2006, Indonesia began to manufacture foil targets using depleted uranium following the procedures established by ANL

  3. Post2012 climate regime options for global GHG emission reduction. Analysis and evaluation of regime options and reduction potential for achieving the 2 degree target with respect to environmental effectiveness, costs and institutional aspects

    Schumacher, Katja; Graichen, Jakob; Healy, Sean [Oeko-Institut, Inst. fuer Angewandte Oekologie e.V., Freiburg im Breisgau (Germany); Schleich, Joachim; Duscha, Vicki [Fraunhofer-Institut fuer Systemtechnik und Innovationsforschung (ISI), Karlsruhe (Germany)

    This report explores the environmental and economic effects of the pledges submitted by industrialized and major developing countries for 2020 under the Copenhagen Accord and provides an in-depth comparison with results arrived at in other model analyses. Two scenarios reflect the lower (''weak'') and upper (''ambitious'') bounds of the Copenhagen pledges. In addition, two scenarios in accordance with the IPCC range for reaching a 2 C target are analyzed with industrialized countries in aggregate reducing their CO2 emissions by 30 % in 2020 compared to 1990 levels. For all four policy scenarios the effects of emission paths leading to a global reduction target of 50 % below 1990 levels in 2050 are also simulated for 2030. In addition, a separate scenario is carried out which estimates the costs of an unconditioned EU 30 % emission reduction target, i.e. where the EU adopts a 30 % emission reduction target in 2020 (rather than a 20 % reduction target), while all other countries stick with their ''weak'' pledges. Not included in the calculations is possible financial support for developing countries from industrialized countries as currently discussed in the climate change negotiations and laid out in the Copenhagen Accord.

  4. School Size, Achievement, and Achievement Gaps

    Bradley J. McMillen

    2004-10-01

    Full Text Available In order to examine the relationship between school size and achievement, a study was conducted using longitudinal achievement data from North Carolina for three separate cohorts of public school students (one elementary, one middle and one high school. Results revealed several interactions between size and student characteristics, all of which indicated that the achievement gaps typically existing between certain subgroups (i.e., more versus less-advantaged, lower versus higher-achieving were larger in larger schools. Results varied across the grade level cohorts and across subjects, but in general effects were more common in mathematics than in reading, and were more pronounced at the high school level. Study results are discussed in the context of educational equity and cost-effectiveness.

    We report a method for estimating people's achievement based on their fame. Earlier we discovered (cond-mat/0310049) that fame of fighter pilot aces (measured as number of Google hits) grows exponentially with their achievement (number of victories). We hypothesize that the same functional relation between achievement and fame holds for other professions. This allows us to estimate achievement for professions where an unquestionable and universally accepted measure of achievement does not exi...

  7. Experience of targeting subsidies on insecticide-treated nets: what do we know and what are the knowledge gaps?

    Worrall, Eve; Hill, Jenny; Webster, Jayne; Mortimer, Julia

    2005-01-01

    Widespread coverage of vulnerable populations with insecticide-treated nets (ITNs) constitutes an important component of the Roll Back Malaria (RBM) strategy to control malaria. The Abuja Targets call for 60% coverage of children under 5 years of age and pregnant women by 2005; but current coverage in Africa is unacceptably low. The RBM 'Strategic Framework for Coordinated National Action in Scaling-up Insecticide-Treated Netting Programmes in Africa' promotes coordinated national action and advocates sustained public provision of targeted subsidies to maximise public health benefits, alongside support and stimulation of the private sector. Several countries have already planned or initiated targeted subsidy schemes either on a pilot scale or on a national scale, and have valuable experience which can inform future interventions. The WHO RBM 'Workshop on mapping models for delivering ITNs through targeted subsidies' held in Zambia in 2003 provided an opportunity to share and document these country experiences. This paper brings together experiences presented at the workshop with other information on experiences of targeting subsidies on ITNs, net treatment kits and retreatment services (ITN products) in order to describe alternative approaches, highlight their similarities and differences, outline lessons learnt, and identify gaps in knowledge. We find that while there is a growing body of knowledge on different approaches to targeting ITN subsidies, there are significant gaps in knowledge in crucial areas. Key questions regarding how best to target, how much it will cost and what outcomes (levels of coverage) to expect remain unanswered. High quality, well-funded monitoring and evaluation of alternative approaches to targeting ITN subsidies is vital to develop a knowledge base so that countries can design and implement effective strategies to target ITN subsidies.

  8. Hemisphericity and student achievement.

    Yeap, L L

    1989-10-01

    Hemispheric preference, the newest element of learning style, refers to the tendency of a person to use one side of the brain to perceive and function more than the other. The objective of the study was to investigate the psychological domain of learning styles in terms of the hemispheric patterns of Singapore Secondary Two students in the three achievement levels, namely Normal (low achievers), Express (average achievers), and Special (high achievers). Using the Cognitive Laterality Battery (Gordon, 1986) to measure the students' hemispheric dominance, the study found that it is in the psychological domain of the students' learning styles, in terms of their hemispheric dominance that the Secondary Two students in the three achievement levels are distinctly different.

    I study the size and sources of the monetary return to college achievement as measured by cumulative Grade Point Average (GPA). I first present evidence that the return to achievement is large and statistically significant. I find, however, that this masks variation in the return across different groups of people. In particular, there is no relationship between GPA and earnings for graduate degree holders but a large and positive relationship for people without a graduate degree. To reconcile...

  11. CERN: Fixed target targets

    Full text: While the immediate priority of CERN's research programme is to exploit to the full the world's largest accelerator, the LEP electron-positron collider and its concomitant LEP200 energy upgrade (January, page 1), CERN is also mindful of its long tradition of diversified research. Away from LEP and preparations for the LHC proton-proton collider to be built above LEP in the same 27-kilometre tunnel, CERN is also preparing for a new generation of heavy ion experiments using a new source, providing heavier ions (April 1992, page 8), with first physics expected next year. CERN's smallest accelerator, the LEAR Low Energy Antiproton Ring continues to cover a wide range of research topics, and saw a record number of hours of operation in 1992. The new ISOLDE on-line isotope separator was inaugurated last year (July, page 5) and physics is already underway. The remaining effort concentrates around fixed target experiments at the SPS synchrotron, which formed the main thrust of CERN's research during the late 1970s. With the SPS and LEAR now approaching middle age, their research future was extensively studied last year. Broadly, a vigorous SPS programme looks assured until at least the end of 1995. Decisions for the longer term future of the West Experimental Area of the SPS will have to take into account the heavy demand for test beams from work towards experiments at big colliders, both at CERN and elsewhere. The North Experimental Area is the scene of larger experiments with longer lead times. Several more years of LEAR exploitation are already in the pipeline, but for the longer term, the ambitious Superlear project for a superconducting ring (January 1992, page 7) did not catch on. Neutrino physics has a long tradition at CERN, and this continues with the preparations for two major projects, the Chorus and Nomad experiments (November 1991, page 7), to start next year in the West Area. Delicate neutrino oscillation effects could become

  20. Target capture and target ghosts

    Auerbach, Steven P.

    1996-05-01

    Optimal detection methods for small targets rely on whitened matched filters, which convolve the measured data with the signal model, and whiten the result with the noise covariance. In real-world implementations of such filters, the noise covariance must be estimated from the data, and the resulting covariance estimate may be corrupted by presence of the target. The resulting loss in SNR is called 'target capture'. Target capture is often thought to be a problem only for bright targets. This presentation shows that target capture also arises for dim targets, leading to an SNR loss which is independent of target strength and depends on the averaging method used to estimate the noise covariance. This loss is due to a 'coherent beat' between the true noise and that portion of the estimated noise covariance due to the target. This beat leads to 'ghost targets', which diminish the target SNR by producing a negative target ghost at the target's position. A quantitative estimate of this effect will be given, and shown to agree with numerical results. The effect of averaging on SNR is also discussed for data scenes with synthetic injected targets, in cases where the noise covariance is estimated using 'no target' data. For these cases, it is shown that the so-called 'optimal' filter, which uses the true noise covariance, is actually worse than a 'sub-optimal' filter which estimates the noise from scene. This apparent contradiction is resolved by showing that the optimal filter is best if the same filter is used for many scenes, but is outperformed by a filter adapted to a specific scene.

    2006-01-01

    Yes, as inferred from panel evidence for inflation-targeting countries and a control group of high-achieving industrial countries that do not target inflation. Our evidence suggests that inflation targeting helps countries achieve lower inflation in the long run, have smaller inflation response to oil-price and exchange-rate shocks, strengthen monetary policy independence, improve monetary policy efficiency, and obtain inflation outcomes closer to target levels. Some benefits of inflation tar...

  3. Achieving empowerment through information.

    Parmalee, J C; Scholomiti, T O; Whitman, P; Sees, M; Smith, D; Gardner, E; Bastian, C

    1993-05-01

    Despite the problems we encountered, which are not uncommon with the development and implementation of any data system, we are confident that our success in achieving our goals is due to the following: establishing a reliable information database connecting several related departments; interfacing with registration and billing systems to avoid duplication of data and chance for error; appointing a qualified Systems Manager devoted to the project; developing superusers to include intensive training in the operating system (UNIX), parameters of the information system, and the report writer. We achieved what we set out to accomplish: the development of a reliable database and reports on which to base a variety of hospital decisions; improved hospital utilization; reliable clinical data for reimbursement, quality management, and credentialing; enhanced communication and collaboration among departments; and an increased profile of the departments and staff. Data quality specialists, Utilization Management and Quality Management coordinators, and the Medical Staff Credentialing Supervisor and their managers are relied upon by physicians and administrators to provide timely information. The staff are recognized for their knowledge and expertise in their department-specific information. The most significant reward is the potential for innovation. Users are no longer restricted to narrow information corridors. UNIX programming encourages creativity without demanding a degree in computer science. The capability to reach and use diverse hospital database information is no longer a dream. PMID:10139109

    NingQuanxin; QiuLizhong

    2004-01-01

    The goal of this study is to improve instructional classes for “Extensive Reading”. We compare two approaches. The traditional method is based on the original procedure; the method we try is a “task-placemented” one. inspired by the method we try is a “task-placemented” one. inspired by the theory of “Tasks of Ascending Difficulty”.This paper provides a comparative evaluation of our experiments on Extensive Reading. Our aim is to resolve the logistical problem of heavy teaching loads and limited class hours, which often prevents English learners from fulfilling their study targets and our intended learning outcomes. In view of the experimental data,we have managed to establish a “feedback” to test the two hypotheses, and demonstrate that the new approach contributes to efficient acquisition of the information in the presented reading materials. Our study concludes with an interpretation of the function and merits of this approach.

  6. How to achieve deterrence

    This paper reports on the present direction of U.S. nuclear weapons policy toward a greater emphasis on counterforce targeting which has caused great concern among members of the public and among many strategic theorists. Although U.S. policy has been moving in this direction for many years, the speed of the movement has increased greatly, with talk of flexible response giving way to that of escalation dominance and nuclear war fighting. The public concern this has raised has led the philosophical community belatedly to begin considering issues such as the morality of nuclear deterrence. But most of the philosophical examinations of this issue have focused on the moral status of nuclear deterrence in general and thus on the choice between nuclear deterrence and unilateral nuclear disarmament. This misses much of the contemporary debate on nuclear weapons policy, which is concerned mainly with the choice between present policy and some form of minimum deterrence

  7. Achieving diagnosis by consensus

    Kane, Bridget

    2009-08-01

    This paper provides an analysis of the collaborative work conducted at a multidisciplinary medical team meeting, where a patient’s definitive diagnosis is agreed, by consensus. The features that distinguish this process of diagnostic work by consensus are examined in depth. The current use of technology to support this collaborative activity is described, and experienced deficiencies are identified. Emphasis is placed on the visual and perceptual difficulty for individual specialities in making interpretations, and on how, through collaboration in discussion, definitive diagnosis is actually achieved. The challenge for providing adequate support for the multidisciplinary team at their meeting is outlined, given the multifaceted nature of the setting, i.e. patient management, educational, organizational and social functions, that need to be satisfied.

To have an all-round command of a language one must be able to speak and to understand the spoken language, it is not enough for a language learner only to have a good reading and writing skills. As Englisn language teachers, we need to focus on improving learners' English speaking skill to meet the need of our society and our country and provide learner some useful techniques to achieving their English spoken fluency. This paper focuses on the spoken how to improving learners speaking skill.

  9. Antiproton Target

    1980-01-01

    Antiproton target used for the AA (antiproton accumulator). The first type of antiproton production target used from 1980 to 1982 comprised a rod of copper 3mm diameter and 120mm long embedded in a graphite cylinder that was itself pressed into a finned aluminium container. This assembly was air-cooled and it was used in conjunction with the Van der Meer magnetic horn. In 1983 Fermilab provided us with lithium lenses to replace the horn with a view to increasing the antiproton yield by about 30%. These lenses needed a much shorter target made of heavy metal - iridium was chosen for this purpose. The 50 mm iridium rod was housed in an extension to the original finned target container so that it could be brought very close to the entrance to the lithium lens. Picture 1 shows this target assembly and Picture 2 shows it mounted together with the lithium lens. These target containers had a short lifetime due to a combination of beam heating and radiation damage. This led to the design of the water-cooled target in...

  11. Entrepreneur achievement. Liaoning province.

    Zhao, R

    1994-03-01

    This paper reports the successful entrepreneurial endeavors of members of a 20-person women's group in Liaoning Province, China. Jing Yuhong, a member of the Family Planning Association at Shileizi Village, Dalian City, provided the basis for their achievements by first building an entertainment/study room in her home to encourage married women to learn family planning. Once stocked with books, magazines, pamphlets, and other materials on family planning and agricultural technology, dozens of married women in the neighborhood flocked voluntarily to the room. Yuhong also set out to give these women a way to earn their own income as a means of helping then gain greater equality with their husbands and exert greater control over their personal reproductive and social lives. She gave a section of her farming land to the women's group, loaned approximately US$5200 to group members to help them generate income from small business initiatives, built a livestock shed in her garden for the group to raise marmots, and erected an awning behind her house under which mushrooms could be grown. The investment yielded $12,000 in the first year, allowing each woman to keep more than $520 in dividends. Members then soon began going to fairs in the capital and other places to learn about the outside world, and have successfully ventured out on their own to generate individual incomes. Ten out of twenty women engaged in these income-generating activities asked for and got the one-child certificate. PMID:12287775

    2014-05-01

    HEPEX is an international initiative bringing together hydrologists, meteorologists, researchers and end-users to develop advanced probabilistic hydrological forecast techniques for improved flood, drought and water management. HEPEX was launched in 2004 as an independent, cooperative international scientific activity. During the first meeting, the overarching goal was defined as: "to develop and test procedures to produce reliable hydrological ensemble forecasts, and to demonstrate their utility in decision making related to the water, environmental and emergency management sectors." The applications of hydrological ensemble predictions span across large spatio-temporal scales, ranging from short-term and localized predictions to global climate change and regional modeling. Within the HEPEX community, information is shared through its blog (www.hepex.org), meetings, testbeds and intercompaison experiments, as well as project reportings. Key questions of HEPEX are: * What adaptations are required for meteorological ensemble systems to be coupled with hydrological ensemble systems? * How should the existing hydrological ensemble prediction systems be modified to account for all sources of uncertainty within a forecast? * What is the best way for the user community to take advantage of ensemble forecasts and to make better decisions based on them? This year HEPEX celebrates its 10th year anniversary and this poster will present a review of the main operational and research achievements and challenges prepared by Hepex contributors on data assimilation, post-processing of hydrologic predictions, forecast verification, communication and use of probabilistic forecasts in decision-making. Additionally, we will present the most recent activities implemented by Hepex and illustrate how everyone can join the community and participate to the development of new approaches in hydrologic ensemble prediction.

    Hill, Amanda Louise; Leinikka Dall, Ole; Andersen, Frits M.

    2014-01-01

    Within the European Union (EU) a paradigm shift is currently occurring in the waste sector, where EU waste directives and national waste strategies are placing emphasis on resource efficiency and recycling targets. The most recent Danish resource strategy calculates a national recycling rate of 22......% for household waste, and sets an ambitious goal of a 50% recycling rate by 2020. This study integrates the recycling target into the FRIDA model to project how much waste and from which streams should be diverted from incineration to recycling in order to achieve the target. Furthermore, it discusses...... how the existing technological, organizational and legislative frameworks may affect recycling activities. The results of the analysis show that with current best practice recycling rates, the 50% recycling rate cannot be reached without recycling of household biowaste. It also shows that all Danish...

    2011-01-01

    The statistics profession is at a unique point in history. The need for valid statistical tools is greater than ever; data sets are massive, often measuring hundreds of thousands of measurements for a single subject. The field is ready to move towards clear objective benchmarks under which tools can be evaluated. Targeted learning allows (1) the full generalization and utilization of cross-validation as an estimator selection tool so that the subjective choices made by humans are now made by the machine, and (2) targeting the fitting of the probability distribution of the data toward the targe

  17. The Sinuous Target

    Zwaska, R. [Fermilab

    2015-06-01

    We report on the concept for a target material comprised of a multitude of interlaced wires of small dimension. This target material concept is primarily directed at high-power neutrino targets where the thermal shock is large due to small beam sizes and short durations; it also has applications to other high-power targets, particularly where the energy deposition is great or a high surface area is preferred. This approach ameliorates the problem of thermal shock by engineering a material with high strength on the micro-scale, but a very low modulus of elasticity on the meso-scale. The low modulus of elasticity is achieved by constructing the material of spring-like wire segments much smaller than the beam dimension. The intrinsic bends of the wires will allow them to absorb the strain of thermal shock with minimal stress. Furthermore, the interlaced nature of the wires provides containment of any segment that might become loose. We will discuss the progress on studies of analogue materials and fabrication techniques for sinuous target materials.

  19. Camouflage target reconnaissance based on hyperspectral imaging technology

    Hua, Wenshen; Guo, Tong; Liu, Xun

    2015-08-01

    Efficient camouflaged target reconnaissance technology makes great influence on modern warfare. Hyperspectral images can provide large spectral range and high spectral resolution, which are invaluable in discriminating between camouflaged targets and backgrounds. Hyperspectral target detection and classification technology are utilized to achieve single class and multi-class camouflaged targets reconnaissance respectively. Constrained energy minimization (CEM), a widely used algorithm in hyperspectral target detection, is employed to achieve one class camouflage target reconnaissance. Then, support vector machine (SVM), a classification method, is proposed to achieve multi-class camouflage target reconnaissance. Experiments have been conducted to demonstrate the efficiency of the proposed method.

    2016-05-01

    Full Text Available In the present research, the recently proposed 3x2 model of achievement goals is tested and associations with achievement emotions and their joint influence on academic achievement are investigated. The study was conducted with 388 students using the 3x2 Achievement Goal Questionnaire including the six proposed goal constructs (task-approach, task-avoidance, self-approach, self-avoidance, other-approach, other-avoidance and the enjoyment and boredom scales from the Achievement Emotion Questionnaire. Exam grades were used as an indicator of academic achievement. Findings from CFAs provided strong support for the proposed structure of the 3x2 achievement goal model. Self-based goals, other-based goals and task-approach goals predicted enjoyment. Task-approach goals negatively predicted boredom. Task-approach and other-approach predicted achievement. The indirect effects of achievement goals through emotion variables on achievement were assessed using bias-corrected bootstrapping. No mediation effects were found. Implications for educational practice are discussed.

    In this paper we introduce a real-time steering controller ensuring the reach of a (possible mobile) target position and orientation, without requiring to build/update the full trajectory to that target. We name it the funnelling control. The final orientation is achieved through the continuous adjustment of the heading direction. This control mode is proactive in the sense that it anticipates the success/failure of the reach and adjusts the desired speed accordingly. Both features rely on an...

    2013-11-01

    Full Text Available Using the Revised Achievement Goal Questionnaire (AGQ-R (Elliot & Murayama, 2008, we explored first-year university students’ achievement goal orientations on the premise of the 2 × 2 model. Similar to recent studies (Elliot & Murayama, 2008; Elliot & Thrash, 2010, we conceptualized a model that included both antecedent (i.e., enactive learning experience and consequence (i.e., intrinsic motivation and academic achievement of achievement goals. Two hundred seventy-seven university students (151 women, 126 men participated in the study. Structural equation modeling procedures yielded evidence that showed the predictive effects of enactive learning experience and mastery goals on intrinsic motivation. Academic achievement was influenced intrinsic motivation, performance-approach goals, and enactive learning experience. Enactive learning experience also served as an antecedent of the four achievement goal types. On the whole, evidence obtained supports the AGQ-R and contributes, theoretically, to 2 × 2 model.

    Schlyer, David J. (Bellport, NY); Ferrieri, Richard A. (Patchogue, NY); Koehler, Conrad (Miller Place, NY)

    1999-01-01

    A target includes a body having a depression in a front side for holding a sample for irradiation by a particle beam to produce a radioisotope. Cooling fins are disposed on a backside of the body opposite the depression. A foil is joined to the body front side to cover the depression and sample therein. A perforate grid is joined to the body atop the foil for supporting the foil and for transmitting the particle beam therethrough. A coolant is circulated over the fins to cool the body during the particle beam irradiation of the sample in the depression.

  9. 12. Target fabrication

    This series of papers presents the requirements and critical issues for IFE (inertial fusion energy) target fabrication and injection. The critical issues for target fabrication are: -) ability to fabricate target capsules and hohlraums, -) ability to fabricate them economically, and -) ability to fabricate, assemble, fill and layer at the required rate. Potential fabrication processes or methodologies include: micro-encapsulation (for foam shells and thick ablators), phase-inversion technique (for CH foams), super-fast cooling techniques, emulsion technique, injection molding (for higher density foam shells), sputter coating (for density high-Z coating), permeation (for DT filling) and cryogenic fluidized beds (for layering of individual capsules). The cooling-induced deformation (CID) of polystyrene shells is characterized in detail (2 papers). Another paper deals with the fabrication of hollow pellets with high Z metal oxide coating of the inner surface. In order to achieve high density compression in laser experiments, the non-contact suspension of pellets is required, Japanese teams propose 2 ways to get it: magnetic suspension and the use of electromagnetic force. The last paper summarizes the major steps in cost reduction that will be taken to economically supply targets for IFE power plants. (A.C.)

  10. Attribution theory in science achievement

    Craig, Martin

    Recent research reveals consistent lags in American students' science achievement scores. Not only are the scores lower in the United States compared to other developed nations, but even within the United States, too many students are well below science proficiency scores for their grade levels. The current research addresses this problem by examining potential malleable factors that may predict science achievement in twelfth graders using 2009 data from the National Assessment of Educational Progress (NAEP). Principle component factor analysis was conducted to determine the specific items that contribute to each overall factor. A series of multiple regressions were then analyzed and formed the predictive value of each of these factors for science achievement. All significant factors were ultimately examined together (also using multiple regression) to determine the most powerful predictors of science achievement, identifying factors that predict science achievement, the results of which suggested interventions to strengthen students' science achievement scores and encourage persistence in the sciences at the college level and beyond. Although there is a variety of research highlighting how students in the US are falling behind other developing nations in science and math achievement, as yet, little research has addressed ways of intervening to address this gap. The current research is a starting point, seeking to identify malleable factors that contribute to science achievement. More specifically, this research examined the types of attributions that predict science achievement in twelfth grade students.

  16. Peer relationships and academic achievement

    Krnjajić Stevan B.

    2002-01-01

    Full Text Available After their childhood, when children begin to establish more intensive social contacts outside family, first of all, in school setting, their behavior i.e. their social, intellectual, moral and emotional development is more strongly affected by their peers. Consequently, the quality of peer relationships considerably affects the process of adaptation and academic achievement and their motivational and emotional attitude towards school respectively. Empirical findings showed that there is bi-directional influence between peer relationships and academic achievement. In other words, the quality of peer relationships affects academic achievement, and conversely, academic achievement affects the quality of peer relationships. For example, socially accepted children exhibiting prosocial, cooperative and responsible forms of behavior in school most frequently have high academic achievement. On the other hand, children rejected by their peers often have lower academic achievement and are a risk group tending to delinquency, absenteeism and drop out of school. Those behavioral and interpersonal forms of competence are frequently more reliable predictors of academic achievement than intellectual abilities are. Considering the fact that various patterns of peer interaction differently exert influence on students' academic behavior, the paper analyzed effects of (a social competence, (b social acceptance/rejection, (c child's friendships and (d prosocial behavior on academic achievement.

    The world is becoming more and more competitive. Quality of performance has become the key factor for personal progress. Parents desire that their children climb the ladder of performance to as high a level as possible. This desire for a high level of achievement puts a lot of pressure on students, teachers, schools, and, in general, the educational system itself. In fact, it appears as if, the whole system of education revolves round the academic achievement of students, though various other...

  18. Reviewing nuclear power station achievement

    For measurement of nuclear power station achievement against original purchase the usual gross output figures are of little value since the term loosely covers many different definitions. An authentically designed output figure has been established which relates to net design output plus house load at full load. Based on these figures both cumulative and moving annual load factors are measured, the latter measuring the achievement over the last year, thus showing trends with time. Calculations have been carried out for all nuclear stations in the Western World with 150 MW(e) gross design output and above. From these are shown: moving annual load factor indicating relative station achievements for all the plants; cumulative load factors from which return of investment can be calculated; average moving annual load factors for the four types of system Magnox, PWR, HWR, and BWR; and a relative comparison of achievement by country in a few cases.

  20. Inertial-confinement-fusion targets

    Much of the research in laser fusion has been done using simple ball on-stalk targets filled with a deuterium-tritium mixture. The targets operated in the exploding pusher mode in which the laser energy was delivered in a very short time (approx. 100 ps or less) and was absorbed by the glass wall of the target. The high energy density in the glass literally exploded the shell with the inward moving glass compressing the DT fuel to high temperatures and moderate densities. Temperatures achieved were high enough to produce DT reactions and accompanying thermonuclear neutrons and alpha particles. The primary criteria imposed on the target builders were: (1) wall thickness, (2) sphere diameter, and (3) fuel in the sphere

  2. Ion acceleration enhanced by target ablation

    Laser proton acceleration can be enhanced by using target ablation, due to the energetic electrons generated in the ablation preplasma. When the ablation pulse matches main pulse, the enhancement gets optimized because the electrons' energy density is highest. A scaling law between the ablation pulse and main pulse is confirmed by the simulation, showing that for given CPA pulse and target, proton energy improvement can be achieved several times by adjusting the target ablation

  10. Establishing seismic design criteria to achieve an acceptable seismic margin

    In order to develop a risk based seismic design criteria the following four issues must be addressed: (1) What target annual probability of seismic induced unacceptable performance is acceptable? (2). What minimum seismic margin is acceptable? (3) Given the decisions made under Issues 1 and 2, at what annual frequency of exceedance should the Safe Shutdown Earthquake ground motion be defined? (4) What seismic design criteria should be established to reasonably achieve the seismic margin defined under Issue 2? The first issue is purely a policy decision and is not addressed in this paper. Each of the other three issues are addressed. Issues 2 and 3 are integrally tied together so that a very large number of possible combinations of responses to these two issues can be used to achieve the target goal defined under Issue 1. Section 2 lays out a combined approach to these two issues and presents three potentially attractive combined resolutions of these two issues which reasonably achieves the target goal. The remainder of the paper discusses an approach which can be used to develop seismic design criteria aimed at achieving the desired seismic margin defined in resolution of Issue 2. Suggestions for revising existing seismic design criteria to more consistently achieve the desired seismic margin are presented

  15. Media and attention, cognition, and school achievement.

    Schmidt, Marie Evans; Vandewater, Elizabeth A

    2008-01-01

    Marie Evans Schmidt and Elizabeth Vandewater review research on links between various types of electronic media and the cognitive skills of school-aged children and adolescents. One central finding of studies to date, they say, is that the content delivered by electronic media is far more influential than the media themselves. Most studies, they point out, find a small negative link between the total hours a child spends viewing TV and that child's academic achievement. But when researchers take into account characteristics of the child, such as IQ or socioeconomic status, this link typically disappears. Content appears to be crucial. Viewing educational TV is linked positively with academic achievement; viewing entertainment TV is linked negatively with achievement. When it comes to particular cognitive skills, say the authors, researchers have found that electronic media, particularly video games, can enhance visual spatial skills, such as visual tracking, mental rotation, and target localization. Gaming may also improve problem-solving skills. Researchers have yet to understand fully the issue of transfer of learning from electronic media. Studies suggest that, under some circumstances, young people are able to transfer what they learn from electronic media to other applications, but analysts are uncertain how such transfer occurs. In response to growing public concern about possible links between electronic media use and attention problems in children and adolescents, say the authors, researchers have found evidence for small positive links between heavy electronic media use and mild attention problems among young people but have found only inconsistent evidence so far for a link between attention deficit hyperactivity disorder and media use. The authors point out that although video games, interactive websites, and multimedia software programs appear to offer a variety of possible benefits for learning, there is as yet little empirical evidence to suggest that

  1. Creativity, knowledge and school achievement

    Maksić Slavica B.

    2004-01-01

    Full Text Available In the process of education the knowledge is acquired which is a necessary base for creativity. The problem of relations between creativity and knowledge in school context is posed as a problem of relations between creativity and academic performance due to the influence it has on personal and professional development of an individual. The paper presents the results of survey on relations between creativity, academic performance and academic preferences. Creativity was measured by the test for creative thinking - drawing production of Urban and Jellen, academic performance by general achievement, and academic preferences by a questionnaire. The sample comprised final primary school graders. Low and statistically significant positive correlation was found between creativity and school achievement in the sub-sample of girls. However, girls have a significantly better school achievement and prefer art as a school subject and the test administered demands visual art expression. Hence, it can not be claimed for sure that the obtained results reflect realistic differences in creativity between boys and girls. It is of vital importance for work in school the data that high creativity can be possessed by students who are failures at school. It has been concluded that initial step in the acquisition of knowledge that will contribute to student creative thinking and behavior is the development of cognitive flexibility.

Overall, ANSTO's capacity to generate value from the application of its knowledge and know-how is being increasingly acknowledged, the organisation attaining credibility as an international leader in the application of nuclear science and technology in targeted areas

  7. The Effects of Chronic Achievement Motivation and Achievement Primes on the Activation of Achievement and Fun Goals

    Hart, William; Albarracín, Dolores

    2009-01-01

    This research examined the hypothesis that situational achievement cues can elicit achievement or fun goals depending on chronic differences in achievement motivation. In 4 studies, chronic differences in achievement motivation were measured, and achievement-denoting words were used to influence behavior. The effects of these variables were assessed on self-report inventories, task performance, task resumption following an interruption, and the pursuit of means relevant to achieving or having...

  14. Challenges in achieving food security in India.

    Upadhyay, R Prakash; Palanivel, C

    2011-12-01

    First Millennium Development Goal states the target of "Halving hunger by 2015". Sadly, the recent statistics for India present a very gloomy picture. India currently has the largest number of undernourished people in the world and this is in spite of the fact that it has made substantial progress in health determinants over the past decades and ranks second worldwide in farm output. The causes of existing food insecurity can be better viewed under three concepts namely the: 'traditional concept' which includes factors such as unavailability of food and poor purchasing capacity; 'socio-demographic concept' which includes illiteracy, unemployment, overcrowding, poor environmental conditions and gender bias; 'politico-developmental concept' comprising of factors such as lack of intersectoral coordination and political will, poorly monitored nutritional programmes and inadequate public food distribution system. If the Millennium Development Goal is to be achieved by 2015, efforts to improve food and nutrition security have to increase considerably. Priority has to be assigned to agriculture and rural development along with promoting women empowerment, ensuring sustainable employment and improving environmental conditions (water, sanitation and hygiene). As the problem is multi-factorial, so the solution needs to be multi-sectoral. PMID:23113100

  17. Target Visualization at the National Ignition Facility

    Potter, Daniel Abraham [Univ. of California, Davis, CA (United States)

    2011-01-01

    As the National Ignition Facility continues its campaign to achieve ignition, new methods and tools will be required to measure the quality of the targets used to achieve this goal. Techniques have been developed to measure target surface features using a phase-shifting diffraction interferometer and Leica Microsystems confocal microscope. Using these techniques we are able to produce a detailed view of the shell surface, which in turn allows us to refine target manufacturing and cleaning processes. However, the volume of data produced limits the methods by which this data can be effectively viewed by a user. This paper introduces an image-based visualization system for data exploration of target shells at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. It aims to combine multiple image sets into a single visualization to provide a method of navigating the data in ways that are not possible with existing tools.

    Full Text Available Pupils with cerebral palsy attend elementary education accordind to a regular and special teaching plan and program. Regular school curriculum was reformed in 1992, while special plan and program has not been changed and adapted according to pupil’s needs and capacities. Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

  19. Achieving Nuclear Sustainability through Innovation

    In 2000, the IAEA Member States recognized that concerted and coordinated research and development is needed to drive innovation that ensures that nuclear energy can help meet energy needs sustainably in the 21st century. Following an IAEA General Conference resolution, an international 'think tank' and dialogue forum were established. The resulting organization, the IAEA's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO), helps nuclear technology holders and users coordinate the national and international studies, research and other activities needed to achieve innovations in nuclear reactor designs and fuel cycles. Currently, 38 countries plus the European Commission are participating in the project. This group includes both developing and developed economies that represent more than 75% of the world's population and 85% of its gross domestic product. INPRO undertakes collaborative projects among IAEA Member States, which analyse development scenarios and examine how nuclear energy can support the United Nations' goals for sustainable development in the 21st century. The results of these projects can be applied by IAEA Member States in their national nuclear energy strategies and can lead to international cooperation resulting in beneficial innovations in nuclear energy technology and its deployment. For example, INPRO studies the 'back end' of the fuel cycle, including recycling of spent fuel to increase resource use efficiency and to reduce the waste disposal burdens.

    The literature has long pointed to heightened frequencies of learning disabilities (LD) within the population of law offenders; however, a systematic appraisal of these observations, careful estimation of these frequencies, and investigation of their correlates and causes have been lacking. Here we present data collected from all youth (1,337 unique admissions, mean age 14.81, 20.3% females) placed in detention in Connecticut (January 1, 2010-July 1, 2011). All youth completed a computerized educational screener designed to test a range of performance in reading (word and text levels) and mathematics. A subsample (n = 410) received the Wide Range Achievement Test, in addition to the educational screener. Quantitative (scale-based) and qualitative (grade-equivalence-based) indicators were then analyzed for both assessments. Results established the range of LD in this sample from 13% to 40%, averaging 24.9%. This work provides a systematic exploration of the type and severity of word and text reading and mathematics skill deficiencies among juvenile detainees and builds the foundation for subsequent efforts that may link these deficiencies to both more formal, structured, and variable definitions and classifications of LD, and to other types of disabilities (e.g., intellectual disability) and developmental disorders (e.g., ADHD) that need to be conducted in future research.

  1. ANSTO - achievements and future directions

    In the opening keynote address to the conference, Professor Helen Garnett, Executive Director of ANSTO, outlined the Organisation's main achievements and its future directions. In the ten years which have elapsed since its inception in 1987, ANSTO has evolved into a forward thinking, proactive nuclear science and technology Organisation. Its vision for the future is for nuclear science and technology to be accepted as benefiting all Australians and for ANSTO to be acknowledged as the premier nuclear science and technology organisation within the Asia Pacific Region. At the same time the organisation has continually reviewed and evaluated what it was doing and how it was doing. At the end of its first decade, it has enhanced the productivity from its research and development activities, received a positive evaluation on the impact that the application of this knowledge is having on the minerals and other industrial sectors, and focussed its research and development into a few areas where substantial teams of ANSTO staff, working cooperatively with staff from universities, other national organisations and industry, can have significant impact. ANSTO now has four parallel activities: the conduct of research and development, the provision of expert technical advice, the operation of national nuclear facilities and the commercial marketing of products and services. The recent announcement by Australian Government to replace HIFAR reactor with a leading medium flux reactor facility, will enable ANSTO to develop world class capability in selected areas of neutron science and to became an acknowledged regional centre, particular in cold neutron science

  3. Magnetic targeted drug delivery

    Timothy Wiedmann

    2009-10-01

    Full Text Available Lung cancer is the most common cause of death from cancer in both men and women. Treatment by intravenous or oral administration of chemotherapy agents results in serious and often treatment-limiting side effects. Delivery of drugs directly to the lung by inhalation of an aerosol holds the promise of achieving a higher concentration in the lung with lower blood levels. To further enhance the selective lung deposition, it may be possible to target deposition by using external magnetic fields to direct the delivery of drug coupled to magnetic particles. Moreover, alternating magnetic fields can be used to induce particle heating, which in turn controls the drug release rate with the appropriate thermal sensitive material.With this goal, superparamagetic nanoparticles (SPNP were prepared and characterized, and enhanced magnetic deposition was demonstrated in vitro and in vivo. SPNPs were also incorporated into a lipid-based/SPNP aerosol formulation, and drug release was shown to be controlled by thermal activation. Because of the inherent imaging potential of SPNPs, this use of nanotechnology offers the possibility of coupling the diagnosis of lung cancer to drug release, which perhaps will ultimately provide the “magic bullet” that Paul Ehrlich originally sought.

  4. Target injection methods for inertial fusion energy

    Petzoldt, R.W.; Moir, R.W.

    1994-06-01

    We have studied four methods to inject IFE targets: the gas gun, electrostatic accelerator, induction accelerator, and rail gun. We recommend a gas gun for indirect drive targets because they can support a gas pressure load on one end and can slide along the gun barrel without damage. With the gas gun, the amount of gas required for each target (about 10 to 100 mg) is acceptable; for other types of targets, a sabot would be necessary. A cam and poppet valve arrangement is recommended for gas flow control. An electrostatic accelerator is attractive for use with lightweight spherical direct drive targets. Since there is no physical contact between the target and the injector, there will be no wear of either component during the injection process. An induction accelerator has an advantage of no electrical contact between the target and the injector. Physical contact is not even necessary, so the wear should be minimal. It requires a cylindrical conductive target sleeve which is a substantial added mass. A rail gun is a simpler device than an electrostatic accelerator or induction accelerator. It requires electrical contact between the target and the rails and may have a significant wear rate. The wear in a vacuum could be reduced by use of a solid lubricant such as MoS{sub 2}. The total required accuracy of target injection, tracking and beam pointing of {plus_minus}0.4 mm appears achievable but will require development and experimental verification.

  5. Achievements and perspectives of ERAWAST

    Dressler R.

    2010-10-01

    Full Text Available The ERAWAST initiative (Exotic Radionuclides from Accelerator Waste for Science and Technology was started at PSI in 2006 and is aimed to acquire resources from the PSI accelerator facilities for the preparation of rare long-lived radionuclides for several scientific purposes [1]. One of the application fields where such radionuclides like 60Fe, 53Mn, 44Ti, 26Al, 7/10Be are urgently needed is nuclear astrophysics. First laboratory-scale separations have been carried out, with the result that two samples of around 1016 atoms of 60Fe each could be provided for experiments [2]. A re-determination of the half-life of 60Fe was performed with the first one [3], and the neutron capture cross section of 60Fe at stellar energies was measured for the first time [4] using the second one. These successes encouraged us to put more efforts into the development of remote- controlled separation systems in order to gain higher amounts and the exploitation of new sources of the desired isotopes. These works are currently ongoing and for the first time, separation of about 5 GBq 7Be from the cooling water of the Swiss Spallation Neutron Source (SINQ was succeeded. Moreover, about 50  g of 10Be are now available after its separation from graphite samples of the target E station at PSI [5]. Considerable amounts of 60Fe, 53Mn, 26Al and others from an irradiated copper beam dump can be expected in the near future. In addition, a scientific program was originated to determine half-lives and neutron capture cross-section of astrophysical interesting radionuclides. In a first step a confirmation of the new measured 60Fe half-life in two independent experiments was started. First studies aimed to re-measure the half-life of 10Be are currently ongoing. Experiments to determine the neutron capture cross-section of 53Mn using cold and ultra-cold neutrons as well as its half-life at PSI are planned.

  6. Effective neutron targets

    Because of the lack of a free neutron target, deuterium targets have been used extensively in studying the neutron structure. The unique spin structure of the 3He ground state wave function and the recent developments in laser technologies made polarized 3He targets widely used in many experiments from neutron electromagnetic form factor studies to nucleon spin structure function measurements at all major electron accelerator facilities. In this talk, the current status of the polarized 3He targets will be reviewed. The author will focus on neutron electromagnetic form factor studies using polarized 3He targets. The polarized nucleon spin structure function measurements using polarized 3He targets will also be discussed

  7. Direct-illumination spherical-target experiments

    A set of spherical target experiments was designed to evaluate the effectiveness of three techniques for achieving higher convergence implosions. They are (1) cryogenically frozen fuel layers, (2) submicron wavelength laser light, and (3) temporally tailored pulse shapes. A second set of experiments provides information about energy transport by thermal and suprathermal electrons and uses multilayered targets as an integral component of the diagnostics. These results, in conjunction with existing laser-target coupling data, provide a more comprehensive test of our understanding of laser plasma interaction, energy transport, and hydrodynamic response of small scale spherical laser fusion experiments

  8. On the Chinese Carbon Reduction Target

    Michinori Uwasu

    2010-06-01

    Full Text Available In November 2009, China pledged a 40–45% decrease in CO2 emissions per GDP by 2020, as compared with the 2005 level. Although carbon intensity (emission targets by nature are ambiguous, this study demonstrates that China’s pledge is consistent with the current Chinese domestic agenda that simultaneously pursues economic growth and energy security. The target numbers in the pledge seem reasonable, given the technological feasibility and measures, considered along with the assumption that moderate economic growth will occur. However, the study also argues that financial and institutional constraints exist as potential obstacles to achieving the target if the trend of the current economic tendencies continues.

  9. Molecular Targets for Targeted Radionuclide Therapy

    Molecular targeted radionuclide cancer therapy is becoming of increasing importance, especially for disseminated diseases. Systemic chemotherapies often lack selectivity while targeted radionuclide therapy has important advantages as the radioactive cytotoxic unit of the targeting vector is specifically directed to the cancer, sparing normal tissues. The principle strategy to improve cancer selectivity is to couple therapeutic agents to tumour-targeting vectors. In targeted radionuclide therapy (TRT), the cytotoxic portion of the conjugates normally contains a therapeutic radiometal immobilised by a bifunctional chelator. The aim is therefore to use as ligand-targeted therapeutics vectors coupled to Auger-, alpha- and/or beta-emitting radionuclides. An advantage of using radiation instead of chemotherapeutics as the cytotoxic agent is the so called 'crossfire effect'. This allows sterilisation of tumour cells that are not directly targeted due to heterogeneity in target molecule expression or inhomogeneous vector delivery. However, before the targeting ligands can be selected, the target molecule on the tumour has to be selected. It should be uniquely expressed, or at least highly overexpressed, on or in the target cells relative to normal tissues. The target should be easily accessible for ligand delivery and should not be shed or down- regulated after ligand binding. An important property of a receptor (or antigen) is its potential to be internalized upon binding of the ligand. This provides an active uptake mechanism and allows the therapeutic agent to be trapped within the tumour cells. Molecular targets of current interest include: Receptors: G-protein coupled receptors are overexpressed on many major human tumours. The prototype of these receptors are somatostatin receptors which show very high density in neuroendocrine tumours, but there are many other most interesting receptors to be applied for TRT. The targeting ligands for these receptors are

  10. Features of photonuclear radionuclide production in the thick targets

    One of the basic requirements for the production technology of radionuclides is to provide a high specific activity of the target nuclide as well as its full activity in target. Traditionally this problem is solved by using a large volume of photonuclear targets with subsequent by radiochemical separation target nuclide. Modeling and experimental study of the spatial distribution of the activity carried out in this work for the various targets. Optimal parameters of irradiation to achieve the maximum yield of isotopes Mo99(Tc99m) and Cu67 in targets from molybdenum and zinc of natural composition have been found.

  12. Fluid mechanics aspects of magnetic drug targeting.

    Odenbach, Stefan

    2015-10-01

    Experiments and numerical simulations using a flow phantom for magnetic drug targeting have been undertaken. The flow phantom is a half y-branched tube configuration where the main tube represents an artery from which a tumour-supplying artery, which is simulated by the side branch of the flow phantom, branches off. In the experiments a quantification of the amount of magnetic particles targeted towards the branch by a magnetic field applied via a permanent magnet is achieved by impedance measurement using sensor coils. Measuring the targeting efficiency, i.e. the relative amount of particles targeted to the side branch, for different field configurations one obtains targeting maps which combine the targeting efficiency with the magnetic force densities in characteristic points in the flow phantom. It could be shown that targeting efficiency depends strongly on the magnetic field configuration. A corresponding numerical model has been set up, which allows the simulation of targeting efficiency for variable field configuration. With this simulation good agreement of targeting efficiency with experimental data has been found. Thus, the basis has been laid for future calculations of optimal field configurations in clinical applications of magnetic drug targeting. Moreover, the numerical model allows the variation of additional parameters of the drug targeting process and thus an estimation of the influence, e.g. of the fluid properties on the targeting efficiency. Corresponding calculations have shown that the non-Newtonian behaviour of the fluid will significantly influence the targeting process, an aspect which has to be taken into account, especially recalling the fact that the viscosity of magnetic suspensions depends strongly on the magnetic field strength and the mechanical load.

  13. Exploiting novel molecular targets in gastrointestinal cancers

    2007-01-01

    Novel molecular targets are being discovered as we learn more about the aberrant processes underlying various cancers. Efforts to translate this knowledge are starting to impact on the care of patients with gastrointestinal cancers. The epidermal growth factor receptor (EGFR) pathway and angiogenesis have been targeted successfully in colorectal cancer with cetuximab, panitunumab and bevacizumab. Similarly, EGFR-targeting with erlotinib yielded significant survival benefit in pancreatic cancer when combined with gemcitabine. The multi-targeting approach with sorafenib has made it the first agent to achieve significant survival benefit in hepatocellular carcinoma. Efforts to exploit the dysregulated Akt/mTOR pathway in GI cancer therapy are ongoing. These molecular targets can be disrupted by various approaches, including the use of monoclonal antibody to intercept extracellular ligands and disrupt receptor-ligand binding, and small molecule inhibitors that interrupt the activation of intracellular kinases.

    Various papers have suggested that Price-Level targeting is a welfare improving policy relative to Inflation targeting. From a practical standpoint, this raises an important yet unanswered question: What is the optimal price index to target? This paper derives the optimal price level targeting index defined over the eight main components of the Consumer Price Index. It finds that such an index places a heavier weight, relative to the expenditure weight, on sectors with slow price adjustments....

    This study analyzes the accuracy of forecasted target prices within analysts’ reports. We compute a measure for target price forecast accuracy that evaluates the ability of analysts to exactly forecast the ex-ante (unknown) 12-month stock price. Furthermore, we determine factors that explain this accuracy. Target price accuracy is negatively related to analyst-specific optimism and stock-specific risk (measured by volatility and price-to-book ratio). However, target price accuracy is positive...

    Meson factories are powerful drivers of diverse physics programs. With beam powers already in the MW-regime attention has to be turned to target and beam line design to further significantly increase surface muon rates available for experiments. For this reason we have explored the possibility of using a neutron spallation target as a source of surface muons by performing detailed Geant4 simulations with pion production cross sections based on a parametrization of existing data. While the spallation target outperforms standard targets in the backward direction by more than a factor 7 it is not more efficient than standard targets viewed under 90°. Not surprisingly, the geometry of the target plays a large role in the generation of surface muons. Through careful optimization, a gain in surface muon rate of between 30% and 60% over the standard "box-like" target used at the Paul Scherrer Institute could be achieved by employing a rotated slab target. An additional 10% gain could also be possible by utilizing novel target materials such as, e.g., boron carbide.

  1. Randomized trial of achieving healthy lifestyles in psychiatric rehabilitation: the ACHIEVE trial

    Guallar Eliseo

    2010-12-01

    Full Text Available Abstract Background Overweight and obesity are highly prevalent among persons with serious mental illness. These conditions likely contribute to premature cardiovascular disease and a 20 to 30 percent shortened life expectancy in this vulnerable population. Persons with serious mental illness need effective, appropriately tailored behavioral interventions to achieve and maintain weight loss. Psychiatric rehabilitation day programs provide logical intervention settings because mental health consumers often attend regularly and exercise can take place on-site. This paper describes the Randomized Trial of Achieving Healthy Lifestyles in Psychiatric Rehabilitation (ACHIEVE. The goal of the study is to determine the effectiveness of a behavioral weight loss intervention among persons with serious mental illness that attend psychiatric rehabilitation programs. Participants randomized to the intervention arm of the study are hypothesized to have greater weight loss than the control group. Methods/Design A targeted 320 men and women with serious mental illness and overweight or obesity (body mass index ≥ 25.0 kg/m2 will be recruited from 10 psychiatric rehabilitation programs across Maryland. The core design is a randomized, two-arm, parallel, multi-site clinical trial to compare the effectiveness of an 18-month behavioral weight loss intervention to usual care. Active intervention participants receive weight management sessions and physical activity classes on-site led by study interventionists. The intervention incorporates cognitive adaptations for persons with serious mental illness attending psychiatric rehabilitation programs. The initial intensive intervention period is six months, followed by a twelve-month maintenance period in which trained rehabilitation program staff assume responsibility for delivering parts of the intervention.

    Recent achievement test results show that Turkish students have been performing poorly compared to students from other countries. Using data from the PISA 2006 survey, we aim to measure the determinants of student achievement in Turkey. We find that the program type the student is enrolled in affects student achievement significantly. However, this effect may partially be biased by past academic achievement. In line with the previous literature, our results also indicate that school resources...
