Farm-made feed for polyunsaturated fatty acids (pufas) rich carp production in India: a case study

An 8 months feed demonstration program was conducted in the ponds of Ramakrishna Mission, Belur Math, West Bengal, India. The program aimed at providing hands-on training to trainees at Samaj Sevak Sikshan Mandir (SSSM) on farm-made feed formulation and use in aquaculture. Two ponds were selected, one at Shilpamandira of 0.1 h and fish were fed Feed-1, and another of 0.08 h at Samaj Sevak Sikshan Mandir (SSSM) and fed Feed-2. Indian major carps, Catla catla (catla) and Labeo rohita (rohu) were stocked at 4500 fish ha-1. The stocking size of rohu was 80-90g and of catla was 220-245g. Locally available low cost feed ingredients, rice bran, mustard oil cake, til oil cake and linseed oil sludge were used to formulate and prepare two farm-made mash feeds (Feed-1 and Feed-2). The fish were fed at 2% of total fish biomass in the ponds and were fed through bag feeding. At the end of the study rohu grew to 1.07 kg and catla to 1.6 kg in Shilpamandira pond (Feed-1), and rohu to1.5 kg and catla to 2.2 kg in Samaj Sevak Sikshan Mandir pond (Feed-2). The net production of fish was 4.9 and 6.8 t ha-1 for 8 months with Feed-1 and Feed-2, respectively. Dietary inclusion of linseed-oilsludge significantly increased the PUFA content in Indian major carps. The feed cost was substantially reduced by replacing mustard oil cake with til oil cake and incorporation of linseed oil sludge, a very low priced ingredient.SAARC J. Agri., 15(2): 45-55 (2017)

The frontline demonstrations were conducted to study the effect of integrated crop management on yield and economics of green chilli at farmer’s field of Tumkuru district, Karnataka state during the year from 2011-12 to 2013-14. The data revealed that the total yield gap between potential yield and actual yield of green chilli was 47.14 per cent, in which 15.00 per cent of yield gap between demonstration plot and actual farmers plot yield and 32.14 per cent of technological gap. The maximum number of farmers adopted recommended spacing (93.33 %) followed by timely irrigation (90.00 %) and harvesting at right stage (90.00 %). The increased in adoption per cent of package of practices were found to more in use of growth regulator for control of flower drops (50.00 %), recommended spacing (43.33 %) and plant protection measures to control pest and diseases (40.00 %). There was significantly increased the yield of green chilli (28.38 %) after conducted the frontline demonstration programme. The net return and B:C ratio were found to increased in demonstrated plot as compared to farmers practice. The adoption of different package of practices even though after demonstrations programme, which shows positive impact of integrated crop management on yield and economics of green chilli through adoption of demonstrated technology.

Mission Design and Performance of RLV-TD

Renewed interest in re-usable launch vehicles has led to the evolution of technology demonstration concepts, where the prime objective is to demonstrate new technologies at reduced cost and shorter turnaround time. This article presents details of both ascent and descent mission design of a low-cost Reusable Launch Vehicle Technology Demonstration (RLV-TD) programme. The technology demonstrator vehicle is boosted to hypersonic Mach number using a solid booster. During ascent phase, the vehicle was flown in a gravity turn trajectory to minimize structural loads on it. In the descent phase, an optimum angle of attack profile as a function of Mach number was computed to limit dynamic pressure, load factor and achieve vehicle trim with minimum control surface deflection. The mission design parameters were evaluated using Monte Carlo analysis utilizing six degrees of freedom simulations. Comparison of actual flight performance with pre-flight prediction is also made this article. Flight performance exhibits close match with the pre-flight predictions.

Evaluation of a model demonstration programme for the control of cervical cancer in rural China: A cross-Sectional study on existing databases from 2009 to 2014

BackgroundSince 2009, a nationwide free cervical cancer screening project in rural China has been gradually expanded. Here, we evaluated a demonstration screening programme in rural China to facilitate the development of the comprehensive guidelines for quality assurance of the cervical cancer screening in Rural China. MethodsThe organised cervical cancer screening programme in Zhushan county was evaluated for both ongoing activities and outcome impact from 2009 through 2014. A descriptive analysis of performance indicators and outcome measures related to screening was conducted. ResultsOf the 73,847 Pap tests performed in 2009–2014, 69127 (93.6%) were in the target age group (25–64). The screening coverages by township were between 10% to 30% in each 2-year screening round. About half of eligible women underwent at least once Pap test over the six-year period. The recall rates for the second and third period were 11.3% and 17.2%, respectively. The annual truncated age-standardized incidence rate seemed to be stable with some variation during the first four years after the initiation of the organised screening programme and dropped in the later two years. ConclusionOur results indicate that the cervical cancer screening programme in Zhushan county was successful in terms of decreasing the cervical cancer burden. Though 2-year coverage was around 18%, the overall 6-year coverage reached 49.5%. We recommend a set of indicators compiled from the regular monitoring process and the methods to estimate the achievement of the programme based on the limited budget and resources available in the area.

Feasibility investigation of a smart thermoacoustic configuration for general aviation aircrafts

One of the most disturbing noise for passengers is related to the engine fan. This noise is mainly tonal and in the low-frequency range. Reducing its impact for the comfort of passengers is an important and challenging issue in aeronautics. One suitable way to reduce cabin noise is to use efficient thermal acoustic insulation blankets between the interior trim panel and the exterior shell. General Aviation Aircrafts, are generally equipped with a cabin poorly efficient both in terms of thermal and acoustic insulation; this due mainly to the not availability of the most innovative solutions or materials like those used on Large Passenger Aircraft. In this context the authors have faced this crucial issue within SPAIN Project “Smart Panels for SAT Aircrafts Cabin Insulation” which makes part of the Systems Integrated Technology Demonstrator (ITD) Program in EU Clean Sky 2. This project aims scientific and technological breakthroughs in the development and validation of new insulation treatments used in aircraft developing a thermo-acoustic insulation system with materials and innovative solutions highly efficient at an affordable cost for this class of aircrafts. According to the available materials on the market with high thermal and acoustic individual performance, SPAIN goal is to design, develop and test an efficient insulation panel suitable for the General Aviation Aircraft compliant with the technical specification in terms of and weight to performance, and cost to performance aspects. Another item that has been strongly worked on, is the integration technology of this solution with the actual interiors configuration with specific focus to maintenance aspects. A set of sandwich configurations have been designed for each specific area of the fuselage to fulfil the overall noise level target; preliminary test have been performed at coupon level and sub-assembly level to confirm the expected outcomes.

After more than 30 years of development, NETDA has played a crucial role in facilitating growth of the economy, industrialization, urbanization, and local development in China. NETDA is generally secondary industry focused and is associated with intensive resource and energy consumption and significant pollution emissions, thus requiring more stringent environmental standards. It is a daunting challenge for NETDAs to balance economic development with resource conservation and environmental protection and support the economy by implementing green development. This study established a green development index (GDI) to assess the degree of environmental friendliness of the Chinese NETDA developments, aiming to establish a baseline to facilitate performance improvement. The GDI was created using a multi-criteria ranking method. First, an index system was established, which included four categories:economic development, water and energy consumption, ecological environmental protection, and infrastructure. Second, the original value of each individual metric was normalized in relation to a benchmark, by transferring both industrial added value and GDP to comparable prices of 2007. The metrics were then weighted and aggregated to calculate the GDI. We then used this method to calculate the GDI evolution of 52 NETDAs. A dynamic bulb-diagram flash was designed to present the GDI evolution of each NETDA from 2007 to 2012 and comparisons among different NETDAs. Differences in GDIs for the NETDAs located in East, Central, and West China were analyzed, as well as the effect of a national demonstration program on eco-industrial park development on GDIs. We found that the GDI improved markedly from 2007 to 2012. The NETDAs accredited as national demonstration eco-industrial parks (EIPs) generally outscored NETDAs that were listed as EIP candidates. Non-EIP NETDAs scored the lowest. Finally, the policy implications of GDI for the NETDAs were discussed. 参考文献 相似文献 引证文献

Key requirements in the procurement of future low observable combat vehicles: a European perspective

AbstractThe aim of this study is to propose guidelines for the systems engineering of future stealth combat vehicles using Low Observable Technology (LOT). A case study approach, based on interviews and document reviews, was used to analyze the systems engineering processes of the SEP multirole armored vehicle and the Visby class corvette respectively. The result is a thorough investigation of what worked in the cases studied, but with lessons extrapolated into recommendations for future development programs. These will have to deal with an increasingly complex sensor threat and a transformed, multilateral, European procurement environment. The main conclusion is that coherence and traceability between military needs on the battlefield and signature requirements is expected to be particularly challenging. A workflow tailored for requirements analysis in LO combat vehicle programs has, therefore, been derived and is presented here. In addition, the most important enablers for future multilateral development programs involving LOT have been identified as: establishing common best practices, demonstrator programs, an integrated product team approach, and, in line with similar work on combat aircraft, establishing stealth as a key architectural principle.

Get SET: aligning anatomy demonstrator programmes with Surgical Education and Training selection criteria.

Prevocational doctors aspiring to surgical careers are commonly recruited as anatomy demonstrators for undergraduate and graduate medical programmes. Entry into Surgical Education and Training (SET) is highly competitive and a unique opportunity exists to align anatomy demonstrator programmes with the selection criteria and core competencies of SET programmes. This study used a qualitative approach to (i) determine what criteria applicants for SET are assessed on and (ii) identify criteria that could be aligned with and enhanced by an anatomy demonstrator programme. The selection guidelines of all nine surgical specialties for the 2017 intake of SET trainees were analysed using qualitative content analysis methodology. The Royal Australasian College of Surgeons adopted a holistic approach to trainee selection that assessed both discipline-specific and discipline-independent skills. Qualitative content analysis identified eight categories of key selection criteria: medical expertise, scholarly activity, professional identity, interpersonal skills, integrity, self-management, insight and self-awareness and community involvement. The structured curriculum vitae was heavily weighted towards discipline-specific skills, such as medical expertise and scholarly activity. Insufficient information was available to determine the weighting of selection criteria assessed by the structured referee reports or interviews. Anatomy demonstrator programmes provide prevocational doctors with unique opportunities to develop surgical skills and competencies in a non-clinical setting. Constructively aligned anatomy demonstrator programmes may be particularly beneficial for prevocational doctors seeking to improve their anatomical knowledge, teaching skills or scholarly activity.

A 10-year review of health care reform on Family Practice Integrated Care Project-Taiwan experience.

Taiwan has launched a Family Practice Integrated Care Project (FPICP) to develop an accountable family doctor system since March 2003. We aim to report the effectiveness of this nationwide demonstration programme over a 10-year period. Papers and reports related to the FPICP published both in English and in Chinese from 2003 to 2015 were collected systematically based on keywords including 'family doctor', 'primary care', 'integrated care' and 'Taiwan'. Also collected and reviewed were national health insurance administration annual reports and related publications from Taiwan Association of Family Medicine. Quality care indicators including structure, process and outcome for programme monitoring were reported. Up to June 2015, the project had enrolled a total of 10.5% of Taiwan's population. Approximately 24.9% of primary care physicians and 29.7% of community clinics joined the project to serve the members of 426 community health care groups (CHCGs). Compared to non-members, CHCG members received more preventive care services, especially in adult health examination (49% versus 19%), Pap smear (29% versus 22%), elderly influenza vaccination (42% versus 28%) and immunochemical faecal occult blood test (43% versus 31%) (P < 0.01). Members showed a markedly high level of satisfaction (>95%), especially in overall satisfaction, provision of health consultation and information, and improvement in understanding personal health condition. In the future, through the support of family physicians and CHCGs, a person-centred integrated health care delivery system can be an effective solution to the current barriers in the medical care system.

Impact of front line demonstrations on the production and productivity of moong (Vigna radiata L), mash (Vigna mungo L), rajmash (Phaseolus vulgaris L), lentil (Lens culinaris L) and chickpea (Cicer aeritinum L) under rainfed ecology in mid hills of J and K, India

Pulses productivity in Jammu Kashmir, India, in North-Western (NW) Himalayas is far less than the national averages because of poor crop management cultivation of low yielding varieties. Frontline demonstration (FLD) program is an effective technology transfer tool for better technology adoption that bridges the yield gaps. The technological extension yield gaps in pulses crops were studied for 3 years during 2009-10 to 2013–2014 under an FLD programme in the Poonch District of Jammu Kashmir, India, revealing that there was a wide yield gap between potential demonstration yields due to technology extension yield gaps. In case of chickpea on the basis of three year mean data demonstrations gave 40.60 % higher yield than local check or farmers practices. Technological yield gaps affecting yield in pulses were highest in chickpea var. BG-1103(13.00 q ha-1) during rabi 2010-11 followed by moong var. SML 668 (12.40 q ha-1) during 2010-11 while lowest gap was observed in rajmash var. local (0.36 q ha-1) during 2011. In general, the technological gaps were highest in chickpea cultivar (BG-1103) lowest in rajmash cultivars in the present study. Extension yield gap varied to the extent of 0.78 to 6.00 q ha-1 in chickpea. In case of lentil, demonstrations gave 12.77 % higher yield over the local check. Extension yield gap varied from 0.25-12.52 q ha-1 in lentil. In case of moong, FLDs gave 71% higher yield than the local check extension yield gap varied from 1.27 to 1.46 qha-1. In case of mash, demonstration gave 35.5% higher yield than farmers average plot yield whereas in case of rajmash on the basis of five year mean data, demonstration gave 28.73% higher yield. Overall, it is inferred that improved farm technology has great potential in enhancing the pulse productivity and profitability through frontline demonstration programme in Poonch district of Jammu Kashmir collateral farming situations in NW -Himalayas as well.

The impact of provider service networks in Florida Medicaid managed care on enrollees’ satisfaction

Two counties in Florida were selected as pilots in 2006 for the Medicaid Demonstration Program. In reform counties, Medicaid enrollees were required to pick a managed care plan; either a Health Maintenance Organization or a Provider Service Network (PSN). PSNs are a form of managed care that provides health care services directly through a provider or network of organizations to a defined population without an intermediary. There are two types of PSNs: Physician-based PSNs and Healthcare system-based PSNs. The objective of this study is to find the differences in enrollees’ satisfaction between two different types of PSNs. To assess the differences in enrollees’ satisfaction between physician-based PSNs and health system-based PSNs over time, this study used difference-in-difference study design with CAHPS data from 2006 to 2008. The study findings showed that, compared to enrollees in physician-based PSNs, health system-based PSN enrollees had higher satisfaction during the post-reform period. However, the trends in satisfaction for enrollees in health system-based PSNs declined at a greater rate relative to the trends for enrollees in physician-based PSNs. Findings from this study may give other states, facing similar decisions to reform their Medicaid managed care system, information to decide whether to adopt a similar plan or to consider other interventions to improve Medicaid beneficiaries’ satisfaction. PSNs are structured similarly to the new accountable care organizations (ACO) models emerging as a result of the Affordable Care Act. Therefore, study findings may be helpful to in improving patient satisfaction with care in ACOs.

Approaches and policies for promoting industrial park recycling transformation (IPRT) in China: Practices and lessons

Industrial park recycling transformation (IPRT) was one of the major circular economy construction demonstration programs in the 12th Five-Year Plan issued by the China State Council in 2012. It comprised of 7 major tasks to transform traditionally high resource and energy intensive production into high efficiency and low pollutant production. By 2017, 129 industrial parks had been approved for IPRT by the National Development and Reform Commission (NDRC). This paper presents a thorough review on IPRT content, policies, and practices, with some lessons and suggestions for further development. Six types of projects were supported by national funds, which included industrial chain extension and complementary projects; water conversion and recycling projects; energy saving projects; pollution prevention projects; platform construction projects; and infrastructure construction sharing projects. Case studies show success for each case. However, deficiencies in industrial development, management, policy-making, and information sharing also emerged. Two suggestions were put forward. First, investment should be diverted from traditional industries to new industries. Past cases have shown that traditional industries have a greater risk of obsolescence. Failure in one park has already created a cascading effect on other enterprises in the park. Secondly, the government-led model should be transformed into a government and market co-led model. The government could establish more effective incentive and restraint mechanisms to attract participation from enterprises and/or social capital. Information sharing platforms, for example, benefit enterprises by increasing awareness for circular economy projects to both private and public actors.

Inertial Navigation System for India’s Reusable Launch Vehicle-Technology Demonstrator (RLV-TD HEX) Mission

This work presents the configuration of Inertial Navigation System (INS) used in India’s Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) Program. In view of the specific features and requirements of the RLV-TD, specific improvements and modifications were required in the INS. A new system was designed, realised and qualified meeting the mission requirements of RLV-TD, at the same time taking advantage of the flight heritage attained in INS through various Launch vehicle Missions of the country. The new system has additional redundancy in acceleration channel, in-built inclinometer based bias update scheme for acceleration channels and sign conventions as employed in an aircraft. Data acquisition in micro cycle periodicity (10 ms) was incorporated which was required to provide rate and attitude information at higher sampling rate for ascent phase control. Provision was incorporated for acquisition of rate and acceleration data with high resolution for aerodynamic characterisation and parameter estimation. GPS aided navigation scheme was incorporated to meet the stringent accuracy requirements of the mission. Navigation system configuration for RLV-TD, specific features incorporated to meet the mission requirements, various tests carried out and performance during RLV-TD flight are highlighted.

Utilization of Concrete Services in Child Welfare: A Mixed Method Analysis of a Title IV-E Waiver Demonstration Program

ABSTRACTConcrete services are goods and services, such as rent, utilities, healthcare, or other tangible services, that are purchased directly by child welfare agencies to help support the short-term needs of a family. Practice wisdom in social work details the importance of meeting basic needs in order for clients to be able to concentrate on completing the case plan. Some literature has mentioned the importance of concrete services for child welfare practice. However, research has been limited about utilization of these services and their impact on child welfare outcomes. The current mixed methods study examines expenditures for concrete services across four categories over a four-year period in one Midwestern state. The justifications for caseworker concrete service requests and the perceptions of regional and executive managers regarding the effectiveness of the use of concrete services are also examined. Descriptive analysis revealed distributions varied by age and concrete service type. Both caseworker justifications and regional manager interviews revealed the same general themes for children: support of child safety, permanency, and well-being are supported with the use of concrete services.

Rapid Re-Housing for Homeless Families Demonstration Programs Evaluation Report Part I: How They Worked - Process Evaluation

Rapid re-housing is a homeless assistance strategy that provides homeless families with immediate, temporary assistance to help them return to permanent housing and to promote their housing and economic stability. This approach has been growing in popularity for 10 years. In 2007, in response to the growing emphasis on rapid re-housing, the U.S. Congress appropriated $23.75 million for the Rapid Rehousing for Homeless Families Demonstration (RRHD) program. As part of its 2008 competitive application for McKinney-Vento Homeless Assistance Act funding, the U.S. Department of Housing and Urban Development (HUD) awarded RRHD grants to 23 communities to serve homeless families with moderate barriers to housing.

Rethinking Performance Based Parking Pricing

In an effort to reduce circling and cruising in cities’ central business districts (CBDs), a number of cities have begun implementing pricing programs that modify parking rates based on observed occupancy levels. We improve on this pricing mechanism by developing a forward-looking policy instrument. The instrument employs a two-stage panel data regression and optimization model that influences demand for parking spaces by changing parking rates via computed price elasticities of parking demand measures. Coefficient estimates that include the elasticity measures from the panel data regression are used to fit a linear prediction model that is the primary input to the optimization model. An application of the approach is presented using SFpark, a federal government-funded demonstration program in San Francisco as a case study. We evaluate the effectiveness of the modified pricing mechanism by comparing actual occupancy and parking rate tuples with the optimized result to ascertain the potential improvement in SFpark’s performance. Policy scenarios are subsequently explored by carrying out sensitivity analysis primarily through SFpark pricing rules. Relative to SFpark’s figures, our model yielded approximately 16% improvement in systems performance when measured by the number of blocks that deviate from the 60 to 80% occupancy target. Our findings highlight the importance of moving towards a predictive regime that allows for proactively managing the parking program compared to a reactive approach based on observed parking occupancy.
