Combined effect of electrical stimulation and blade tenderization on some bovine muscles

Energy Technology Data Exchange (ETDEWEB)

Raccach, M.; Henrickson, R.L.

1979-01-01

The electrical stimulation (ES) period was a very important factor determining the tenderness of three bovine muscles: Biceps femoris (BF), Longissimus dorsi (LD), and Semimembranosus (SM). Tenderness (shear force values) increased in most cases with increasing the ES period. An ES period of 15 min was optimal for obtaining a tenderness equal to that obtained by conventional processing of beef. The shortest ES period used (1 min) was adequate in most cases to set the muscles in rigor mortis and in preventing cold shortening. The tenderness of blade tenderized muscles was in most cases independent from the ES period. Blade tenderization was very effective to tenderize the BF muscle followed in decreasing order of efficacy by the LD and SM muscles. The cooking times and cooking losses of the three muscles were not affected by either the ES period or by blade tenderization.

Formalized description of assessment procedures of tender offers (of the construction organizer and contracting companies in case of engineering control scheme

Directory of Open Access Journals (Sweden)

Sborshchikov Sergey Borisovich

2016-10-01

Full Text Available The procedure of evaluating and selecting tender offers is not only an important element of the control system of investment and construction activity but is also an effective tool to increase its efficiency due to optimization of construction works price, reduction of their duration, stimulating innovations in the production, increasing the quality and engineering safety of construction production. At the recent time when new organizational forms and control schemes of investment and construction activity are appearing the system of competitive bidding gains more importance and new functions, because the choice of construction organizer and contracting companies directly influences the results of the construction. The authors consider the task of selecting the bidders’ offers which is a multicriterion task. The offers are evaluated according to the set of parameters reflecting the effectiveness of investment and construction projects. The criteria selection is based on the fact that the proposals of the organizer of construction and the contractors are related to the cost of works and to the deadlines which directly affects the implementation parameters of investment and construction projects.

. The main renewable energy markets in Latin America and the Caribbean are dominated by tendering processes, a trend that is likely to continue in the coming years. But whereas tenders are predicated on competition, community-driven projects are based on collaboration. Participating in tendering processes - and winning - requires, among others, significant expertise and access to large reserves of capital, which smaller actors do not have to the same degree as large, specialist renewable energy developers. Under the tendering process, even if their projects are financially viable, actors that take a one-project approach - including community-driven renewable energy projects - are penalised against large developers, which can distribute the costs and risks of tendering to several projects. Tenders can be modified to favour a diversity of actors and community-driven renewable energy projects through the use of various tendering design options. Applying these design options often results in a trade-off between the primary objective - contracting the cheapest electricity from renewables - and the secondary objective of promoting a diversity of actors. As one solution, in the accession process following the tender, community-driven projects can be offered a power purchase agreement at a tariff based on the result of the tender. The accession process captures both the efficiency of tenders and the effectiveness of feed-in tariffs for community projects. Setting limits, in time and quantity, for the implementation of the accession process is necessary to ensure its dynamic efficiency. The accession process would be greatly strengthened and accelerated by the establishment of ambitious, but realistic, mid- and long-term targets for community-driven renewable energy projects. Complementing the accession process, it is proposed that a community power authority be established, with the roles of providing technical, legal and business support; assigning official &apos

A recently discovered tea [Camellia sinensis (L.) O. Kuntze] cultivar can generate tender shoots in winter. We performed comparative proteomics to analyze the differentially accumulated proteins between winter and spring tender shoots of this clonal cultivar to reveal the physiological basis of its evergrowing character during winter. We extracted proteins from the winter and spring tender shoots (newly formed two leaves and a bud) of the evergrowing tea cultivar "Dongcha11" respectively. Thirty-three differentially accumulated high-confidence proteins were identified by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF / TOF MS). Among these, 24 proteins had increased abundance while nine showed were decreased abundance in winter tender shoots as compared with the spring tender shoots. We categorized the differentially accumulated proteins into eight critical biological processes based on protein function annotation including photosynthesis, cell structure, protein synthesis & destination, transporters, metabolism of sugars and polysaccharides, secondary metabolism, disease/defense and proteins with unknown functions. Proteins with increased abundance in winter tender shoots were mainly related to the processes of photosynthesis, cytoskeleton and protein synthesis, whereas those with decreased abundance were correlated to metabolism and the secondary metabolism of polyphenolic flavonoids. Biochemical analysis showed that the total contents of soluble sugar and amino acid were higher in winter tender shoots while tea polyphenols were lower as compared with spring tender shoots. Our study suggested that the simultaneous increase in the abundance of photosynthesis-related proteins rubisco, plastocyanin, and ATP synthase delta chain, metabolism-related proteins eIF4 and protease subunits, and the cytoskeleton-structure associated proteins phosphatidylinositol transfer protein and profilin may be because of the adaptation of the

The integration of price/cost modelling and construction planning - the automated generation of construc­tion operation

Directory of Open Access Journals (Sweden)

P. A. Bowen

1997-07-01

Full Text Available The fact that traditional price/cost models are unrelated to the construction process renders them largely unsuited to the provision of meaningful price/cost advice. The nature and lengthiness of the construction planning process has precluded its incorporation into price/cost modelling during the pre-tender phase of the traditional building procurement process. The nub of the modelling problem has been how to integrate the complex process of construction planning into the pre-tender price/cost modelling process. In this paper the authors propose the synthesis of artificial intelligence techniques and construction planning techniques, resulting in a conceptual framework for a network-based cost modelling system for use by quantity surveyors in the cost modelling of buildings.

Annila, L

2000-01-01

ST division has implemented certain procedures to handle the calls for tender and market surveys. In January 1998, the division leader set up the 'call-for-tender co-ordination office' to check and approve each technical document leaving the division. The mandate of the call-for-tender co-ordination office is to check the quality of the documents, in order for these documents to be as clear as possible in terms of both content and structure. The role of this office is to contribute positively and give service to the people writing the documents, and not to give negative criticism. The aim of this paper is to present the mandate of the office, how papers are processed, and to draw up a first result summary.

Italian water service's competitive tendering: does any tender design exist?

International Nuclear Information System (INIS)

Antonioli, B.

2006-01-01

During the last two decades, the procurement of public services has been engaged a process of intensive change, both at the local and national level, particularly in Europe. In Italy, recent developments of legislative framework are aimed to adopt competitive tenders both for service's concession or private partner selection. Economists and operators generally agree about the effectiveness of auctions for the concession's contracting out. Otherwise, the agreement is weaker if the question is how to prepare the auction: bidding market a la Demsetz, beauty contests or hybrid forms? In other words, more attention should be devoted to the analysis of reference market and to auction's design. The aim of this paper is to verify, starting from the analysis of auction realized between 1998 and 2005, the real designing of the auctions other than the presence of an idea of industrial policy for water services. Results highlights that tenders are few, poorly designed and scarcely effective. To be more precise, results remark the lack of foresight of industrial policy and, more generally, the necessity to reflect on the real possibility of the competition for thc market in the water sector, characterized by an high degree of economical and social complexity [it

The responses of pH, ºBrix, CIE colour (L*, a* and b* value and OAA were studied. The data obtained were analysed by multiple regression technique to generate suitable mathematical models. The developed blended beverage was processed using pulsed electric field (PEF with electric field 31.2 kV/cm, 20 pulse widths at 100 Hz frequency to minimise nutritional and sensory attributes losses and compared with conventional thermal pasteurization (96 ºC for 360 s with p-value of 8.03. Thermal pasteurization showed a significant (p<0.05 decrease in colour value, radical scavenging activity and overall acceptability after treatment and also during storage, when compared to PEF treated tender coconut water-nannari blended beverage. PEF treatment also achieved a 3.01 ± 0.69 log inactivation, similar to thermal pasteurization of native micro flora. PEF treated tender coconut water-nannari blended beverage was stable up to 120 days under ambient storage condition (27-30 °C.

Evaluating the Impact of Risk on Contractor’s Tender Figure in Public Buildings Projects in Northern Nigeria

Directory of Open Access Journals (Sweden)

L. O. Oyewobi

2012-01-01

Full Text Available It has become almost impossible to have projects completed within the initial cost and time in Nigeria; this is as a result of many factors the construction industry is being plagued with ranging from estimating risk to time and cost overruns. The construction industry is widely associated with a high degree of risk and uncertainty due to the nature of its operating heterogeneous environment. The paper aimed at evaluating the impact of estimating risk on contractor’s tender sum with a view of ensuring efficient delivery of projects in the Northern part of Nigeria. A survey was conducted using questionnaire and a total of four headings of risk factors were identified. Research findings showed defects in design, inflation, contractor’s competence and political uncertainty as well as changes in government had greatest impact on contractor’s tender figure whereas likely trend in wages rates over the period, excessive approval procedure in administration government department, unavailability of sufficient amount of unskilled labor and technical manpower and resources of the company were the most significant factors to be considered by contractors when estimating the pricing risk. The paper recommends that construction professionals should identify and adequately quantify project estimating risk factors. Adding a risk premium to quotation and time estimation has to be supported by governmental owner organizations and other agencies in the local construction sector. Competent contractors should be allowed to tender so as to see the incidence of these estimating risks as an important aspect that requires attention while evaluating contractor’s tender sum.

Leveraging Lean in construction: A case study of a BIM-based HVAC manufacturing process

Directory of Open Access Journals (Sweden)

Colin J. Conway

2014-12-01

Full Text Available The impetus towards efficiency in the AECO (Architecture, Engineering, Construction & Operations sector is driving the implementation of Lean practices. BIM technologies and BIM processes provide methods by which this can be achieved. Major clients of building services contractors have begun to mandate the use of BIM and some are using BIM preparedness/experience as pre-tender qualification criteria. In this case study, an initial review has been conducted of the achievements of a major Irish M&E contractor in implementing BIM. The firm purpose-built a facility for the off-site manufacture of building services components. The operations of the plant are efficient and quality assured through the use of an appropriately skilled workforce at all stages of manufacture, and tracking software that has developed as the knowledge of the contractor grew. Standardised processes have been developed which have resulted in greater efficiencies and lower costs for the contractor as a result of fewer requirements for onsite modifications (such as those caused by clashes, less waste, and greater flexibility. Despite some initial objections, the employees of the company are now more satisfied with their working conditions and are, as a result, more productive. Through investment in BIM-based, Lean processes, the contractor can now better compete when tendering for large-scale projects in Ireland and worldwide, including the rapidly-increasing number where BIM experience and preparedness is mandated.

Beef tenderness improvement by dietary vitamin D3 supplementation in the last stage of fattening of cattle

Directory of Open Access Journals (Sweden)

Półtorak Andrzej

2017-03-01

Full Text Available Tenderness is the most important characteristic of meat, determining consumer approval. There are numerous methods of its improvement, although of diverse effectiveness. addition of vitamin D3 to the feed for a short period before slaughter (7–10 days is one of the natural ways to enhance the tenderness. Vitamin D3 is responsible for Ca2+ mobilisation in serum and increase in activity of proteolytic enzymes belonging to calpains, which results in significant improvement of beef tenderness and reduction of ageing time. The use of vitamin D3 is an application tool determining tenderness improvement of beef with substantial reduction in processing costs. Moreover, shorter post mortem ageing process will exceed the retail display time, which will consequently reduce losses due to unsold meat being returned from shops to the manufacturers. Based on the results of studies conducted over the last 15 years, this paper presents the possibility and the effects of the use of vitamin D3 to improve beef tenderness.

Managing meat tenderness.

Thompson, John

2002-11-01

This paper discusses the management of meat tenderness using a carcass grading scheme which utilizes the concept of total quality management of those factors which impact on beef palatability. The scheme called Meat Standards Australia (MSA) has identified the Critical Control Points (CCPs) from the production, pre-slaughter, processing and value adding sectors of the beef supply chain and quantified their relative importance using large-scale consumer testing. These CCPs have been used to manage beef palatability in two ways. Firstly, CCPs from the pre-slaughter and processing sectors have been used as mandatory criteria for carcasses to be graded. Secondly, other CCPs from the production and processing sectors have been incorporated into a model to predict palatability for individual muscles. The evidence for the importance of CCPs from the production (breed, growth path and HGP implants), pre-slaughter and processing (pH/temperature window, alternative carcass suspension, marbling and ageing) sectors are reviewed and the accuracy of the model to predict palatability for specific muscle×cooking techniques is presented.

Survey of billing and coding for counterstrain tender points.

Science.gov (United States)

Snider, Karen T; Johnson, Jane C

2012-06-01

The names of certain counterstrain tender points are incongruent with their physical locations because of an assumption that these points are reflective of dysfunction in neighboring body areas. Because the body area that is physically examined does not always match the body region in which somatic dysfunction is diagnosed for these tender points, it is not always clear which evaluation and management service codes should be used for billing physician services. To assess the attitudes of osteopathic physicians toward the billing and coding of incongruent counterstrain tender points. Physician members of the American Academy of Osteopathy who use counterstrain in clinical practice were surveyed regarding the body area that they would physically examine when assessing for incongruent tender points and, if tender points were present, the body regions to which they would assign somatic dysfunction for billing and coding purposes. Physician responses were categorized as indicating a structural approach (ie, reflective of anatomic location) or a functional approach (ie, reflective of dysfunction in neighboring body areas) to tender point examination and treatment. Associations between sex, specialty, and years in practice with the approach chosen were also examined. Of 175 physicians who responded to the survey, 156 met the study criteria. Respondents were primarily board-certified in neuromusculoskeletal medicine/osteopathic manipulative medicine (98 [63%]), special proficiency in osteopathic manipulative medicine (30 [19%]), or family practice/family practice and osteopathic manipulative treatment (94 [60%]). Ninety percent of physicians predominantly chose responses indicating a structural approach to the physical examination of tender points and 21% predominantly chose responses indicating a functional approach to somatic dysfunction diagnosis. There were inconsistencies among individual respondents regarding the type of approach chosen for a single tender point. For

The aim of this study was to evaluate the accuracy of classification of Nellore beef aged for 0, 7, 14, or 21 days and classification based on tenderness and aging period using a bench-top hyperspectral imaging system. A hyperspectral imaging system (λ = 928-2524 nm) was used to collect hyperspectral images of the Longissimus thoracis et lumborum (aging n = 376 and tenderness n = 345) of Nellore cattle. The image processing steps included selection of region of interest, extraction of spectra, and indentification and evalution of selected wavelengths for classification. Six linear discriminant models were developed to classify samples based on tenderness and aging period. The model using the first derivative of partial absorbance spectra (give wavelength range spectra) was able to classify steaks based on the tenderness with an overall accuracy of 89.8%. The model using the first derivative of full absorbance spectra was able to classify steaks based on aging period with an overall accuracy of 84.8%. The results demonstrate that the HIS may be a viable technology for classifying beef based on tenderness and aging period.

Kamil, A. I. M.; Othman, N.; Adnan, H.; Zaki, ZA M.

2018-02-01

The occurrence of overrun in cost and time in a project that is usually caused by contractors, will generally make peopleput the blameonthem. This happensas a result of the lack of knowledge possessed by the contractors in determining the solution to be undertakendue totheir mistakes, especially when it comes to tendering process as what had happened in the cases that were reported in Supreme Court of Canada. This paper aims to identify the types of mistakes, factors that contribute to the mistakes and the responsiveness to the mistakes so that the contractor will be able to manage and control the mistakes, as well as the solution, along with preventing them from happening, and in making decision whether or notthey may withdraw from the bidding when the fault has been discovered or whether they should request for leniency from the client for a second chance in re-submitting the bid after the discovered inaccuracy. This research has been done based on cases that were related to the contractor’s mistakes during tendering which were collected from the Supreme Courts of Canada. The data have been analysed and interpreted by legal methodology, in which the result shows that the ability level of the contractors to respond to the mistake is unsatisfactory,and the fault is continuouslybeingmade. The findings are expected to educate and provide awareness to the contractors relating to the matters discussed.

Relationships between sensory evaluations of beef tenderness, shear force measurements and consumer characteristics.

Science.gov (United States)

Van Wezemael, Lynn; De Smet, Stefaan; Ueland, Øydis; Verbeke, Wim

2014-07-01

The supply of tender beef is an important challenge for the beef industry. Knowledge about the profile of consumers who are more optimistic or more accurate in their tenderness evaluations is important for product development and beef marketing purposes. Central location tests of beef steaks were performed in Norway and Belgium (n=218). Instrumental and sensorial tenderness of three muscles from Belgian Blue and Norwegian Red cattle was reported. Consumers who are optimistically evaluating tenderness were found to be more often male, less food neophobic, more positive towards beef healthiness, and showed fewer concerns about beef safety. No clear profile emerged for consumers who assessed tenderness similar to shear force measurements, which suggests that tenderness is mainly evaluated subjectively. The results imply a window of opportunities in tenderness improvements, and allow targeting a market segment which is less critical towards beef tenderness. © 2013 Elsevier Ltd. All rights reserved.

Proposed Model for Integrating RAMS Method in the Design Process in Construction

Directory of Open Access Journals (Sweden)

Saad Al-Jibouri

2010-05-01

Full Text Available There is a growing trend in the Netherlands for outsourcing public construction activities to the private sector through the use of integrated contracts. There is also an increasing emphasis from public clients on the use of RAMS and life cycle costing (LCC in the design process of infrastructural projects to improve the performance of designed systems and optimize the project cost. RAMS is an acronym for `reliability, availability, maintainability and safety' and represents a collection of techniques to provide predictions of the performance targets of the required system. Increasingly, RAMS targets are being specified in invitation to tender or contract documents and the parties responsible for the design are required to provide evidence of its application in their design. Recent evidence from practice, complemented with a literature study, has shown that the knowledge and application of RAMS in infrastructural designs are in their infancy compared with other industrial sectors and many designers in construction do not have the necessary knowledge and experience to apply it. This paper describes a proposed model for the integration of RAMS and LCC into the design process in construction. A variation of the model for the application of RAMS in `design, build, finance and maintain' (DBFM contracts that include maintenance requirements is also proposed. The two models involve providing guidelines to simplify the application of RAMs by the designers. The model has been validated for its practicality and usefulness during a workshop by experienced designers.

Described is tender-assisted drilling (TAD) on the UK North Sea Gannet field. The Gannet field is developed by Shell UK Exploration and Production (Shell Expro). In March 1990, Shell Expro awarded Sedco Forex the design and engineering contract to convert the semisubmersible drilling rig Sedco 704 into the Gannet TSV (Tender Support Vessel). The only semisubmersible TSV operation so far to have completed drilling in the North Sea has been in the Norwegian sector. The Odin field, operated by Esso Norge a/s, was developed using the converted drilling rig Treasure Hunter. 1 fig., 1 ill., 3 refs.

Background Vulvodynia is a chronic vulvar pain disorder and fibromyalgia is a chronic widespread musculoskeletal pain disorder; both of unknown etiology. Association of these conditions is well documented. Intra-vaginal algometer measurement of tenderness to pressure applied to the pelvic floor muscles helps to define vulvodynia associated with musculoskeletal factors. Women with both vulvodynia and fibromyalgia might have increased pelvic muscle pain compared to women with vulvodynia alone, defining the possible link of these two conditions. Objective 1) correlate pain intensity during the non-genital tender point tenderness examination to pain intensity with the vaginal algometer in women with provoked vestibulodynia, 2) determine whether subjects with provoked vestibulodynia and fibromyalgia had higher pain intensity scores with the vaginal algometer than those without fibromyalgia. Study Design Ninety-two subjects referred for vulvar pain were confirmed to have provoked vestibulodynia using the cotton swab test. A diagnosis of fibromyalgia was made if pain was present (Numerical rating scale> 1) in at least 11 sites of the 18-point non-genital tender point tenderness exam. Vaginal pain sensitivity was measured using an intra-vaginal pressure algometer, where 0.1, 0.3, and 0.5 kg/cm2 forces were applied digitally in random assignment by force and location to the right and left iliococcygeus muscle regions and the posterior vaginal wall. Both tender point tenderness and algometer pain intensity were reported on a 0 (no pain) to 10 (worse pain) numeric rating scale. Correlations were computed between the composite pain intensity (total of rating scale from each pressure threshold at specified site) of non-genital and those of iliococcygeus regions and the posterior vaginal wall. Independent t-tests were used to determine differences in iliococcygeus regions and the posterior vaginal algometer pain ratings and presence or absence of fibromyalgia. The significance

Tender-assisted drilling (TAD) involves the use of tender support vessel (TSV) during the drilling phase of platform development to provide drilling utilities to the platform-mounted drilling package. The TSV provides facilities such as mud mixing, storage, pumping, bulk storage, hotel accommodations, and power. Thus, the platform topsides and jacket weight and size can be smaller and less expensive. The paper discusses the advantages and disadvantages of TAD, then describes the TAD vessel, semisubmersible, platform cost savings, accommodations, drilling and workovers, and field experience.

Environmental Criteria in the Spanish Public Works Procurement Process

Directory of Open Access Journals (Sweden)

José Luis Fuentes-Bargues

2017-02-01

Full Text Available Green Public Procurement (GPP is defined as a process of contracting products, services, and works with the least possible damage to the environment during their life cycle. In order to improve the knowledge about GPP, a study of the use of environmental tendering criteria in the Spanish public construction sector has been performed. The results of this study show that the use of environmental criteria in Spanish public sector construction procurement is low in comparison to a certain group of countries, known as “Green 7”, in the European Union. Environmental criteria is the fourth criterion in importance, but its weight in the global of the process is much lower than other criteria such as price, memory of the construction process and the delivery time. National administrations use environmental criteria more frequently because they have more resources and staff training about environmental issues. Environmental criteria are more used in the tendering of civil projects and works whose budget exceeds ten million euro due to the environmental impact of these kind and/or size of projects.

Grounds for dispensing with public tender procedures in Government Contracting

Directory of Open Access Journals (Sweden)

P Bolton

2006-01-01

Full Text Available The Constitution of the Republic of South Africa1 provides that organs of state must comply with five principles when procuring goods or services: procurement procedures must be fair, equitable, transparent, competitive and cost-effective. In short, this means that organs of state should make use of competition when procuring goods or services. They should shop around and attract the maximum number of contractors who will participate in such competition. The aim should be the attainment of value for money, meaning, public money should be spent in an effective and efficient manner. Those who participate in competitions should also be treated fairly and without bias. In principle, no preferences should be afforded to different contractors; all contracting parties should have equal access to competition; some contractors should not be afforded more time for the preparation and submission of quotes or tenders than others; and the same information should be made available to all contracting parties. Government procurement procedures should further be transparent, meaning public or open. Thus, organs of state should not contract behind closed doors – government contracts should, as a rule, be advertised. Depending on the nature and value of a particular contract, the use of a public call for tenders is generally the best way to ensure compliance with the principles in the Constitution. By nature, a pubic call for tenders is open, it assists in the prevention of fraud and favouritism, and it ensures that the maximum number of contractors is approached to compete for a contract.Organs of state can also compare prices and quality and can contract with whoever offers the best deal. Most legislation therefore proceeds on the basis that procurement takes place by way of tendering. Generally, contracts above R200 000 are subject to public tender procedures. In certain instances, however, a public call for tenders may be inappropriate regardless of the high

Optimizing strategy for repetitive construction projects within multi-mode resources

Directory of Open Access Journals (Sweden)

Remon Fayek Aziz

2013-03-01

Full Text Available Estimating tender data for specific project is the most essential part in construction areas as of a contractor’s view such as: proposed project duration with corresponding gross value and cash flows. Cash flow analysis of construction projects has a long history and has been an important topic in construction management. Determination of project cash flows is very sensitive, especially for repetitive construction projects. This paper focuses on how to calculate tender data for repetitive construction projects such as: project duration, project cost, project/bid price, project cash flows, project maximum working capital and project net present value that is equivalent to net profit at the beginning of the project. A simplified multi-objective optimization formulation will be presented that creates best tender data to contractor comparing with more feasible options that are generated from multi-mode resources in a given project. This mathematical formulation is intended to give more scenarios which provide a practical support for typical construction contractors who need to optimize resource utilization in order to minimize project duration, project/bid price and project maximum working capital while maximizing its net present value simultaneously. At the end of the paper, an illustrative example will be presented to demonstrate the applications of proposed technique to an optimization expressway of repetitive construction project.

2010-09-01

To investigate the degree of nonarticular tenderness and functional status in patients with diffuse idiopathic skeletal hyperostosis (DISH). We assessed these variables' correlation with their clinical, radiographic, and constitutional measurements and with metabolic syndrome (MS). Eighty-seven patients with DISH were compared with 65 controls without DISH. Examination of nonarticular tenderness was performed by thumb palpation. Tenderness was scored for the 18 fibromyalgia tender points (TP), and 4 control points. Nonarticular tenderness was expressed by the number of TP and by the total tenderness score (TTS). The Short Health Assessment Questionnaire (HAQ II) was administered to all participants. Clinical and laboratory data were collected from all patients. Patients were classified as having MS by both the National Cholesterol Education Program and World Health Organization definitions. There was a statistically significant difference in TTS between controls and patients with DISH. The mean tenderness of many individual TP was significantly higher in the DISH group compared with the control group. TP counts, TTS, and body mass index (BMI) positively correlated with the HAQ II. There was a linear trend in intensity of T-spine bony bridges (BB) and the total number of TP as well as many individual TP. Patients with DISH were more likely to be affected by MS. No correlation was found between TP count, TTS, and MS. Patients with DISH have a lower pain threshold than patients who do not have DISH. TP count and TTS correlate with the functional status, BMI, waist circumference, and high-grade BB. No correlation was observed between pain threshold and MS.

Geesink, Geert; Sujang, Sadi; Koohmaraie, Mohammad

2011-08-01

Lamb longissimus muscle (n=6) sections were cooked at different times post mortem (prerigor, at rigor, 1dayp.m., and 7 days p.m.) using two cooking methods. Using a boiling waterbath, samples were either cooked to a core temperature of 70 °C or boiled for 3h. The latter method was meant to reflect the traditional cooking method employed in countries where preparation of prerigor meat is practiced. The time postmortem at which the meat was prepared had a large effect on the tenderness (shear force) of the meat (PCooking prerigor and at rigor meat to 70 °C resulted in higher shear force values than their post rigor counterparts at 1 and 7 days p.m. (9.4 and 9.6 vs. 7.2 and 3.7 kg, respectively). The differences in tenderness between the treatment groups could be largely explained by a difference in contraction status of the meat after cooking and the effect of ageing on tenderness. Cooking pre and at rigor meat resulted in severe muscle contraction as evidenced by the differences in sarcomere length of the cooked samples. Mean sarcomere lengths in the pre and at rigor samples ranged from 1.05 to 1.20 μm. The mean sarcomere length in the post rigor samples was 1.44 μm. Cooking for 3 h at 100 °C did improve the tenderness of pre and at rigor prepared meat as compared to cooking to 70 °C, but not to the extent that ageing did. It is concluded that additional intervention methods are needed to improve the tenderness of prerigor cooked meat. Copyright © 2011 Elsevier B.V. All rights reserved.

Improving Tenderness of Spent Layer Hens Meat Using Papaya Leaves (Carica papaya

Full Text Available Two experiments were performed to study the use of papaya leaves as a meat tenderizer. The first experiment was to evaluate the effect of papaya dry leaves added to hen’s diet before slaughter. Spent hens (n=48 were used, half of them were fed a concentrate ration containing10% dried papaya leaves powder (DPLP while others received layer ration (Control, for 10 days. The second experiment involved a comparison between papaya leaves juice (PLJ, fresh papaya leaves (FPL and vinegar solution (VS as marinades applied to meat for one or two hours before cooking. Spent layer hens (n=42 were used for tenderness evaluation method. After slaughtering and preparing the chickens two methods of cooking were used (oven and moist cooking. The cooked parts (breast, thigh and drumstick were subjected to a panel test evaluation according to a designed questionnaire. Addition of dried papaya leaves powder to spent layer hens ration significantly (P≤0.05 increased the level of meat tenderness. Moist cooking had significantly (P≤0.05 improved meat tenderization compared to oven cooking. Meat treated with fresh papaya leaves had significantly (P≤0.05 improved tenderness. It was concluded that wrapping the tough meat of spent layer hens with fresh papaya leaves for one hour and moist cooking improve tenderness of meat.

Gertrude Stein’s Tender Buttons (1911)

DEFF Research Database (Denmark)

Balle, Søren Hattesen

Gertrude Stein’s book of prose poems Tender Buttons has been characterized as a modernist literary work by most of its critics. As a distinctive feature of its modernist poetics critics in particular emphasize Stein’s denial of representation through verbal abstraction and autotelism. This paper......, however, intends to read Tender Buttons somewhat differently by suggesting that the poems may be viewed as an example of a displaced Rabbinic hermeneutics in the sense given the term by Susan Handelman. Inasmuch as Stein refuses to name the many objects properly that the titles of the poems introduce...... and instead – to employ her own term – “abuses” their names by way of wordplay, punning, syntactical ambiguity, and semantic disruption, she impersonates a secular Reb Stein, who stays faithful to the Scripture by sacred contempt of representation and obedience to (the play of) the letter. Perhaps...

Even though there was no progress in privatisation of a 40-percent stake in Slovenske elektrarne (SE), a.s., Bratislava a government decree on re-opening of the tender issued in July will allow more prospects to participate. New prospects that are expected to submit their offers are Czech CEZ and American AES. At the same time the original eight prospects that submitted their offers earlier will have the opportunity to withdraw from the tender or review their offers. The new prospects can show their interest in requesting a information memorandum that will be published shortly and then PricewaterhouseCoopers (PwC) will state a date when the offers have to be submitted. After the original offers are updated and the new ones submitted, the offers will be evaluated. Representative of PwC, Peter Mitka refused to discuss the evaluation deadlines and the consecutive due diligence in SE to be conducted by selected investors. The company to have restarted the whole process was the Czech CEZ that had announces its intention to privatise not only the conventional part of SE but the nuclear part as well. The remaining prospects only show interest in hydraulic power plants or conventional power plants but none of them is interested in nuclear power plants. Even though the process is still open and theoretically other prospects could show their interest in the future, Minister of Economy, Robert Nemcsics does not expect that this step would be repeated. And so the number of prospects is ten. In the past the Minister expressed his view that the most suitable solution would be so sell the SE as a whole and during the first press conference given together with privatisation advisor the Minister explained that there was no time-pressure in regards to the privatisation process as an internal restructuring of the company had to be completed first

In April 2013, local authorities gained responsibility for commissioning sexual health services in England. With many services going out to tender and resultant change in services or service provider, there is anecdotal evidence that this has impacted on the education, training and morale of genitourinary medicine (GUM) trainees. The aim of this study was to evaluate the impact of tendering on GUM trainees. An electronic survey designed by the British Association for Sexual Health and HIV Trainees' Collaborative for Audit, Research and Quality Improvement Projects (T-CARQ) was distributed to GUM trainees and newly appointed consultants. Eighty-two individuals responded (74% GUM trainees, 25% newly appointed consultants, 1% locum appointed for service). Sixty-three per cent (45/72) had experience of training within a service which was being tendered. Of these, 59% (24/41) felt their training was not considered during the tendering process and 20% (8/41) felt that it was. Forty-four per cent (18/41) felt adequately supported. Thirty per cent (12/40) reported active participation in the tendering process. On a scale of 0 (no impact) to 5 (major impact), the median score for impact of tendering on training was 2. The positive/negative impact of tendering on different training elements was rated: other than management experience the overall impact on all parameters was negative, namely morale, senior support and education. In conclusion, this survey describes the variable impact of service tendering on GUM training. Our recommendations for maintaining training standards despite tendering include actively involving trainees and education partners, inclusion of specialist GUM training in service specifications, development of guidance for commissioners and services for the management of GUM training within tendering.

Production and processing studies on calpain-system gene markers for tenderness in Brahman cattle: 2. Objective meat quality.

Effects and interactions of calpain-system tenderness gene markers on objective meat quality traits of Brahman (Bos indicus) cattle were quantified within 2 concurrent experiments at different locations. Cattle were selected for study from commercial and research herds at weaning based on their genotype for calpastatin (CAST) and calpain 3 (CAPN3) gene markers for beef tenderness. Gene marker status for mu-calpain (CAPN1-4751 and CAPN1-316) was also determined for inclusion in statistical analyses. Eighty-two heifer and 82 castrated male cattle with 0 or 2 favorable alleles for CAST and CAPN3 were studied in New South Wales (NSW), and 143 castrated male cattle with 0, 1, or 2 favorable alleles for CAST and CAPN3 were studied in Western Australia (WA). The cattle were backgrounded for 6 to 8 mo and grain-fed for 117 d (NSW) or 80 d (WA) before slaughter. One-half the cattle in each experiment were implanted with a hormonal growth promotant during feedlotting. One side of each carcass was suspended from the Achilles tendon (AT) and the other from the pelvis (tenderstretch). The M. longissimus lumborum from both sides and the M. semitendinosus from the AT side were collected; then samples of each were aged at 1 degrees C for 1 or 7 d. Favorable alleles for one or more markers reduced shear force, with little effect on other meat quality traits. The size of effects of individual markers varied with site, muscle, method of carcass suspension, and aging period. Individual marker effects were additive as evident in cattle with 4 favorable alleles for CAST and CAPN3 markers, which had shear force reductions of 12.2 N (P 0.05) of interactions between the gene markers, or between the hormonal growth promotant and gene markers for any meat quality traits. This study provides further evidence that selection based on the CAST or CAPN3 gene markers improves meat tenderness in Brahman cattle, with little if any detrimental effects on other meat quality traits. The CAPN1-4751 gene

To pilot methodologies designed to critically assess the American College of Rheumatology's (ACR) diagnostic criteria for fibromyalgia. Prospective, psychophysical testing. An urban teaching hospital. Twenty-five patients with fibromyalgia and 31 healthy controls (convenience sample). Pressure pain threshold was determined at the 18 ACR tender points and five sham points using an algometer (dolorimeter). The patients "algometric total scores" (sums of the patients' average pain thresholds at the 18 tender points) were derived, as well as pain thresholds across sham points. The "algometric total score" could differentiate patients with fibromyalgia from normals with an accuracy of 85.7% (P pain across sham points than across ACR tender points, sham points also could be used for diagnosis (85.7%; Ps tested vs other painful conditions. The points specified by the ACR were only modestly superior to sham points in making the diagnosis. Most importantly, this pilot suggests single points, smaller groups of points, or sham points may be as effective in diagnosing fibromyalgia as the use of all 18 points, and suggests methodologies to definitively test that hypothesis.

We conducted three experiments to determine the effects of the callipyge phenotype on the tenderness of several major lamb muscles and to determine the effect of method of cookery on the tenderness of callipyge lamb at 7 d postmortem. In Exp. 1, chops from normal (n = 23) and callipyge (n = 16) carcasses were open-hearth-broiled. Warner-Bratzler shear force values of longissimus, gluteus medius, semimembranosus, biceps femoris, semitendinosus, adductor, and quadriceps femoris were 123, 44, 28, 26, 19, 16, and 13% greater, respectively, for callipyge (P lamb carcasses (n = 60). Callipyge chops were less tender than normal chops (P cooking method, callipyge samples were less juicy than normal samples (P < .05). These data demonstrate that the callipyge phenotype will likely reduce consumer satisfaction due to reduced tenderness and juiciness; however, reduced tenderness in callipyge leg muscles could be prevented by ovenroasting.

Tender point count, pain, and mobility in the older population: the mobilize Boston study.

Science.gov (United States)

Eggermont, Laura H P; Shmerling, Robert H; Leveille, Suzanne G

2010-01-01

Prevalence of tender points (TP), and widespread pain and fibromyalgia, as well as the relationship between TP and widespread pain and mobility, was examined in 585 community-dwelling older adults (mean age 78.2 years, 63.4% female). Pain was based on location (none, single site, multisite, widespread). Mobility was measured by the Short Physical Performance Battery (SPPB), gait speed, and self-reported (S-R) mobility difficulty. Tender-point count and health characteristics (ie, BMI, chronic conditions, analgesic use, number of medications, depression, and blocks walked per week) were assessed. Several participants had 3 or more TP (22.1%) although prevalence of criteria-based fibromyalgia was low (.3%). Mobility was more limited in persons with higher tender-point counts. After adjustment for pain and other risk factors, higher tender-point count was associated with poorer SPPB performance (score < 10, aOR = 1.09 per TP, 95%CI, 1.01-1.17), and slow gait speed (< .784m/sec, aOR = 1.14 per TP, 95%CI, 1.05-1.24), but not with S-R mobility difficulty. S-R mobility difficulty was associated with more disseminated pain (multisite pain, aOR = 2.01, 95%CI, 1.21-3.34; widespread pain, aOR = 2.47, 95%CI, 1.09-5.62). These findings portray a significant mobility burden related to tender-point count and multisite and widespread pain in the older population. Future studies using longitudinal methods are warranted. Higher tender-point count, multisite pain, and widespread pain are common in community-dwelling older adults and associated with mobility problems. Both the manual tender-point exam and the McGill Pain Map may provide important yet different information about risks for mobility disability in older individuals.

2015-07-01

Full Text Available Objectives: to establish a relationship between widespread pain subjectively perceived and threshold pain tolerance on tender points, and to determine whether there are differences in threshold pain tolerance on tender points between the upper and lower body, as well as between the dominant and non-dominant side, and whether these differences have an impact on the daily life of Portuguese women with fibromyalgia (FM. Material e Methods: thirty-one women with FM aged between 34 and 67 years volunteered for the study. Threshold pain tolerance was assessed at critical points using a digital algometer pressure; the widespread pain index (WPI was constructed by the addition of 19 painful body regions; and the impact on the daily life assessed by the Portuguese version of the Fibromyalgia Impact Questionnaire (FIQ, with individual interviews. Results: significant differences between the percentage of threshold pain tolerance of the whole body and the scales of widespread pain subjectively perceived were observed, showing that the widespread pain subjectively perceived by patients was between +25.9% and +27.5%. Also, significant differences between threshold pain tolerance of tender points located on the upper and lower body (1.9 ± 0.5 kg/cm2 vs. 2.6 ± 0.7 kg/cm2; respectively were observed. However, no significant differences were found between threshold pain tolerance of tender points located on dominant and non-dominant sides (2.1 ± 0.5 kg/cm2 e 2.1 ± 0.6 kg/cm2; respectively. Additionally, the analysis showed significant correlations between pain and patient`s daily life in: FIQ total score, physical function, feel good, job ability and fatigue. Conclusions: the women with FM show higher widespread pain subjectively perceived than threshold pain tolerance on tender points. Furthermore, the pain suffered by the patients with FM, especially that located on the upper body, either on the dominant or on the non-dominant side, has a negative

Full Text Available The public tenders are very important instrument which the public sector uses to the allocation of great part of public expenditure for Welfare of citizens. Due to the the lack of resources and the optimal use of it in line with the public interest and the rights of tenderers tenders play a key role in the public sector operations they can be defined as an instrument to increase the effectiveness of the public sector as a whole. But with the conflict of interests of the public and private sector there needs to be transparency so that the rights of the parties to maintain and public confidence in the state increase. Transparency in Tenders cause the Suppliers that win the bids are those with the best product at the best price targeted at achieving the best outcome. This paper examines the concept and types of tenders for the effects of transparency in government tenders.

Tender frequency and market concentration in balancing power markets

Knaut, Andreas; Obermueller, Frank; Weiser, Florian

2017-01-01

Balancing power markets ensure the short-term balance of supply and demand in electricity markets and their importance may increase with a higher share of fluctuating renewable electricity production. While it is clear that shorter tender frequencies, e.g. daily or hourly, are able to increase the efficiency compared to a weekly procurement, it remains unclear in which respect market concentration will be affected. Against this background, we develop a numerical electricity market model to quantify the possible effects of shorter tender frequencies on costs and market concentration. We find that shorter time spans of procurement are able to lower the costs by up to 15%. While market concentration decreases in many markets, we - surprisingly - identify cases in which shorter time spans lead to higher concentration.

The Role of Quality in the Adjudication of Public Tenders

Directory of Open Access Journals (Sweden)

Geo Quinot

2014-08-01

Full Text Available The quality of the goods or services that government procures is obviously a very important consideration in deciding which supplier should be awarded a particular public tender. It follows that in the regulation of public procurement, particular attention should be given to the role of quality (also called functionality in the adjudication of public tenders and the final award decision. In South African public procurement law, the role of functionality in public tender adjudication has been a fairly controversial issue that has resulted in a continuing interaction between courts and law-makers on how and when quality should be assessed and should impact on the final award decision within the framework for public procurement found in section 217 of the Constitution. This contribution tracks the development of the role of functionality in public tender adjudication as prescribed by public procurement regulation since the enactment of the Preferential Procurement Policy Framework Act 5 of 2000, which spearheaded the development of contemporary public procurement regulation in South Africa. The analysis shows how the role of functionality has constantly changed since the enactment of the PPPFA and remains uncertain. This uncertainty relates to different interpretations of the constitutional requirements for public procurement primarily contained in section 217(1 of the Constitution. Whether functionality is used as a qualification criterion, an award criterion or both holds particular practical implications for both suppliers and contracting authorities. It is accordingly important to have certainty on this question. However, it cannot be said that the Constitution and section 217 in particular dictates one approach rather than another. The issue should thus be resolved with reference to the statutory scheme adopted under the PPPFA.

The author comments the answers to a call for tender made by the French government and concerning five offshore wind farm sites (Le Treport, Fecamp, Courseulles sur Mer, Saint-Brieuc and Saint-Nazaire). As they are present within the three consortiums, Areva and Alstom should provide the wind turbines. This would result in the construction by Alstom of two blade and mast factories and two turbine and pad factories. For both companies, this market of 500 to 600 turbines is an opportunity. Many jobs are at stake. They push themselves forward for their experience or their innovation capacity. But their wind turbines will be based on foreign (Spanish or German) technology

Estimation of Sensory Pork Loin Tenderness Using Warner-Bratzler Shear Force and Texture Profile Analysis Measurements.

Science.gov (United States)

Choe, Jee-Hwan; Choi, Mi-Hee; Rhee, Min-Suk; Kim, Byoung-Chul

2016-07-01

This study investigated the degree to which instrumental measurements explain the variation in pork loin tenderness as assessed by the sensory evaluation of trained panelists. Warner-Bratzler shear force (WBS) had a significant relationship with the sensory tenderness variables, such as softness, initial tenderness, chewiness, and rate of breakdown. In a regression analysis, WBS could account variations in these sensory variables, though only to a limited proportion of variation. On the other hand, three parameters from texture profile analysis (TPA)-hardness, gumminess, and chewiness-were significantly correlated with all sensory evaluation variables. In particular, from the result of stepwise regression analysis, TPA hardness alone explained over 15% of variation in all sensory evaluation variables, with the exception of perceptible residue. Based on these results, TPA analysis was found to be better than WBS measurement, with the TPA parameter hardness likely to prove particularly useful, in terms of predicting pork loin tenderness as rated by trained panelists. However, sensory evaluation should be conducted to investigate practical pork tenderness perceived by consumer, because both instrumental measurements could explain only a small portion (less than 20%) of the variability in sensory evaluation.

Full Text Available Tenderness is one of the most important properties of meat quality, which is influenced by genetic and environmental factors. As an intensively studied epigenetic marker, histone methylation, occurring on arginine and lysine residues, has pivotal regulatory functions on gene expression. To examine whether histone methylation involves in beef tenderness variation, we analyzed the transcriptome and H3K4me3 enrichment profiles of muscle strips obtained from the longissimus dorsi (LD of Angus steers previously classify to the tender or tough group. We first plotted a global bovine H3K4me3 map on chromosomes and called peak-enriched regions and genes. We found that majorities of H3K4me3 on genes were occupying the first intron and intergenic regions and its maps displayed similar patterns in tender and tough groups, with high H3K4me3 enrichment surrounding the transcription start site (TSS. We also explored the relationship of H3K4me3 and gene expression. The results showed that H3K4me3 enrichment is highly positively correlated with gene expression across the whole genome. Cluster analysis results confirmed the relationship of H3K4me3 enrichment and gene expression. By using a pathway-based approach in genes with H3K4me3 enrichment in promoter regions from the tender cluster, we revealed that those genes involved in the development of different tissues-connective tissue, skeletal and muscular system and functional tissues-; while in tough group those genes engaged in cell death, lipid metabolism and small molecule biochemistry. The results from this study provide a deep insight into understanding of the mechanisms of epigenetic regulations in meat quality and beef tenderness.

To tender, re-negotiate or partner: Strategies for contracting service companies

International Nuclear Information System (INIS)

Gouldie, T.A.

1994-01-01

The contracting of oilfield service companies by petroleum exploration and production operating companies is different than the contracting of civil engineering, construction or other project-oriented contractors. The relationship between operating companies and oilfield service companies has had a long and unique history which has evolved since the first oil wells were drilled over a century ago. The process of contracting service companies by operating companies for petroleum exploration and production work can be split into three distinct stages: (1) decide what it is that should be contracted out and what should be kept in house; (2) determine the method to use to select the contractor(s) to perform the work; and (3) agree to the contractual structure to best reflect the relationship the operating company and the service company with to initiate and maintain. As there are ongoing changes to the business structures and corporate thinking of both operating and service companies, there are also evolving changes to what are considered core businesses and the methods of selecting and contracting service companies by operating companies. Operating companies are recognizing the high costs of tendering for contractor services in terms of personnel time and administrative effort, and are relying more on negotiating and rolling-over existing contracts with their suitable, capable contractors. Partnering, in its many forms and levels, is increasingly being recognized as a useful method to get better work done at cheaper overall costs

Utilization of BIM for automation of quantity takeoffs and cost estimation in transport infrastructure construction projects in the Czech Republic

Science.gov (United States)

Vitásek, Stanislav; Matějka, Petr

2017-09-01

The article deals with problematic parts of automated processing of quantity takeoff (QTO) from data generated in BIM model. It focuses on models of road constructions, and uses volumes and dimensions of excavation work to create an estimate of construction costs. The article uses a case study and explorative methods to discuss possibilities and problems of data transfer from a model to a price system of construction production when such transfer is used for price estimates of construction works. Current QTOs and price tenders are made with 2D documents. This process is becoming obsolete because more modern tools can be used. The BIM phenomenon enables partial automation in processing volumes and dimensions of construction units and matching the data to units in a given price scheme. Therefore price of construction can be estimated and structured without lengthy and often imprecise manual calculations. The use of BIM for QTO is highly dependent on local market budgeting systems, therefore proper push/pull strategy is required. It also requires proper requirements specification, compatible pricing database and software.

Full Text Available The Fibromyalgia is a syndrome of pain and chronic diffuse, characterized by the presence of at least 11 of 18 points called anatomically specific tender points, painful on palpation. As the pain diffuse the main symptom of fibromyalgia. The current treatment is focused mainly to the reduction of symptoms. Physiotherapy has animportant role in improving the control of pain. This study aimed to verify the effectiveness of the main TENS of low frequency and high intensity in modulating pain of tender points of patients with fibromyalgia. For this was a case study of patient R. S. S., 38-yearold female carrier of the syndrome of fibromyalgia attended school in the clinic of the Faculty of Integrated Ceará (FISIOFIC. The patient was treated with the TENS-pain Acupuncture points in a total of twelve care and pain assessed before starting treatment and after three attendants. There was a significant reduction in pain intensity at 77.7% of the tender points in the second evaluation and 88.8% of the points in the other assessments. It was concluded that there was a reduction in the pain of tender points of the patient showing the analgesia promoted by TENS, so it should be used as a complementary treatment programs associated with other treatments and also served as a good technique to locate the tender points.

We used the FM impact questionnaire (FIQ) to assess FM severity and symptomatology. Patients were categorised according to three FIQ-derived categories: FIQFIQFIQ≥59 (16.9±2 vs. 15.6±4, p=0.02), whereas no differences between groups were observed according to FIQ≥70 (17.0±2 vs. 16.2±3, p=0.12) or FM type (16.8±3 for type II vs. 15.9±4 for type I, p=0.13). We observed a significant association between TPC and FIQ-job difficulty, pain, morning tiredness and stiffness dimensions (all pFIQ, FIQ-anxiety, fatigue and depression dimensions (all p>0.05). Algometer score was lower in the FIQ≥70 (45.7±12 vs. 51.1±14, p=0.05) and FIQ≥59 (46.7±13 vs. 52.7±14, p=0.05) groups, and there were no difference between FM types (48.7±13 vs. 49.5±14 for type II and I respectively, p=0.81). Algometer score was not associated with total score of FIQ or FIQ dimensions (all p≥0.1). Widespread pain and pain hypersensitivity, as measured by TPC and algometer score, do not seem to be useful to characterise FM severity and symptomatology (measured by FIQ) in women.

2013-09-01

Full Text Available Estimating tender data for specific project is the most essential part in construction areas as of contractor’s view such as: proposed project duration with corresponding gross value and cash flows. This paper focuses on how to calculate tender data using Optimizing Strategy Software (OSS for repetitive construction projects with identical activity’s duration in case of single number of crew such as: project duration, project/bid price, project maximum working capital, and project net present value of the studied project. A simplified multi-objective optimization software (OSS will be presented that creates best tender data to contractor compared with more feasible options generated from multi-mode resources in a given project. OSS is intended to give more scenarios which provide practical support for typical construction contractors who need to optimize resource utilization in order to minimize project duration, project/bid price, and project maximum working capital while maximizing its net present value simultaneously. OSS is designed by java programing code system to provide a number of new and unique capabilities, including: (1 Ranking the obtained optimal plans according to a set of planner specified weights representing the relative importance of duration, price, maximum working capital and net present value in the analyzed project; (2 Visualizing and viewing the generated optimal trade-off; and (3 Providing seamless integration with available project management calculations. In order to provide the aforementioned capabilities of OSS, the system is implemented and developed in four main modules: (1 A user interface module; (2 A database module; (3 A running module; (4 A connecting module. At the end of the paper, an illustrative example will be presented to demonstrate and verify the applications of the proposed software (OSS to an optimization expressway of repetitive construction project.

Bowling, M B; Vote, D J; Belk, K E; Scanga, J A; Tatum, J D; Smith, G C

2009-05-01

A study was conducted to determine if reflectance measurements made in the near-infrared region of the spectrum were additive to reflectance measurements made in the visible region of the spectrum for predicting Warner-Bratzler shear force (WBSF) values. Eighty seven strip loins were collected following fabrication over 3d at a commercial beef processing facility from heifer carcasses with Slight or Traces marbling scores. Spectroscopic measurements were made at approximately 50h postmortem using a Hunter-Lab UltraScan. Subsequently, all strip loins were aged for 14d, cooked to an internal temperature of 70°C, and sheared to obtain WBSF values. Reflectance measurements obtained in the near-infrared region of the spectrum were correlated with WBSF values, however, these measurements were not additive to the predictive ability of reflectance measurements (R(2) values did not differ) made in the visible portion of the spectrum when the use of broad-band wavelength filters were simulated. It was therefore determined, that both the visible and near-infrared spectra measure reflectance and that both methods are acceptable methods of tenderness prediction.

2015-01-01

Tender points in the neck are common in patients with temporomandibular disorders (TMD). However, the correlation among neck disability, jaw dysfunction, and muscle tenderness in subjects with TMD still needs further investigation. This study investigated the correlation among neck disability, jaw dysfunction, and muscle tenderness in subjects with and without chronic TMD. Participants. Forty females between 19 and 49 years old were included in this study. There were 20 healthy controls and 20 subjects who had chronic TMD and neck disability. Subjects completed the neck disability index and the limitations of daily functions in TMD questionnaires. Tenderness of the masticatory and cervical muscles was measured using an algometer. The correlation between jaw disability and neck disability was significantly high (r = 0.915, P cervical muscles with jaw dysfunction and neck disability showed fair to moderate correlations (r = 0.32-0.65). High levels of muscle tenderness in upper trapezius and temporalis muscles correlated with high levels of jaw and neck dysfunction. Moreover, high levels of neck disability correlated with high levels of jaw disability. These findings emphasize the importance of considering the neck and its structures when evaluating and treating patients with TMD.

Despite a common misconception, older adults engage in sexual behavior. However, there is limited sexual behavior research in older adults, which is often restricted to small samples, to cohorts recruiting adults from 45 years old, and to questions regarding only sexual intercourse. To assess the cross-sectional prevalence of and characteristics associated with sexual activity and physical tenderness in community-dwelling older adults. From the Rotterdam Study, sexual activity and physical tenderness were assessed in 2,374 dementia-free, community-dwelling men and women at least 65 years old from 2009 through 2012 in the Netherlands. Analyses were stratified by sex and partner status. Sexual activity and physical tenderness (eg, fondling or kissing) in the last 6 months. Potential associated characteristics included measurements of demographics, socioeconomic position, health behavior, and health status. The vast majority of partnered participants (men, n = 858; women, n = 724) had experienced physical tenderness in the previous 6 months (83.7% of men and 82.9% of women) and nearly half had engaged in sexual activity (49.5% and 40.4% respectively). Very few unpartnered women (n = 675) had engaged in sexual activity (1.3%) or physical tenderness (5.2%), whereas prevalence rates were slightly higher for unpartnered men (n = 117; 13.7% or 17.1%). Engaging in sexual behavior was generally associated with younger age, greater social support, healthier behaviors, and better physical and psychological health. Findings show that older adults engage in sexual activity. It is important not to assume that an older person is not interested in sexual pleasure or that an older person is unhappy with not having a sexual partner. Offering an opportunity for open discussion of sexuality and medical assistance without imposing is a difficult balance. We encourage health care professionals to proactively address sexuality and extend knowledge about safe sex and sexual function

2016-01-01

Full Text Available Construction industry is recognized as high fragmentation, low efficiency, cost and time overruns in contrast with other industries. These peculiarities are the main roots of poor performance facing by the industry. Effective coordination is vital in construction projects success and mitigate the fragmentation dilemma, however it is often difficult to achieve and need iterative process. Coordination is core issue to improve performance in construction project. Relevant studies have addressed the coordination process importance and implementation, but not in a framework. This paper propose a framework for coordination process in construction projects, as well as its relationship with performance. The objective of the framework is to provide a roadmap for the construction parties to realize operational excellence so that collectively stakeholders can recognize the effect of coordination process application on the project performance. The data were obtained from literature review and structured interviews with five experts. The analysis produced the framework of coordination based on the extensively used procedures for information and data flow between stakeholders.

Starkey, Colin P; Geesink, Geert H; Collins, Damian; Hutton Oddy, V; Hopkins, David L

2016-03-01

The longissimus (n=118) (LL), semimembranosus (n=104) (SM) and biceps femoris (n=134) (BF) muscles were collected from lamb and sheep carcases and aged for 5days (LL and SM) and 14days (BF) to study the impact of muscle characteristics on tenderness as assessed by shear force (SF) and sensory evaluation. The impact of gender, animal age, collagen content, sarcomere length (SL), desmin degradation, ultimate pH and intramuscular fat (IMF) on tenderness was examined. The main factors which influenced SF of the LL were IMF, SL and desmin degradation, but for sensory tenderness, IMF, ultimate pH and gender were the main factors. The SF and sensory tenderness of the SM was best predicted by the degree of desmin degradation. For the BF soluble collagen and animal age both influenced SF. Different factors affect tenderness across muscles and not one prediction model applied across all muscles equally well. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available Beef tenderness is an important trait in consumer satisfaction and has been considered as the main trait for palatability, for which reason it is important to evaluate its variability in different cattle breeds. An experiment was designed to evaluate the Warner Bratzler Shear Force (WBSF of Red Brangus cattle rib eye steaks and consumer acceptance. The tenderness of beef rib eye steaks was evaluated by the WBSF. A consumer preference evaluation test was carried out to quantitatively estimate tenderness, juiciness, flavor, doneness and general acceptance of the evaluated steaks. Mean WBSF was 5.03 kg ± 0.93 kg, theoretically indicating a tough beef. The distribution of the samples showed 21 % and 11 % of moderately tender and tender beef cuts, respectively. Cattle condition (bulls and steers was not significant for the WBSF (p > 0.5. All the traits evaluated in the hedonic evaluation had approximately 6 points of a total of 8 (8 was best. Tenderness, juiciness and flavor presented a high and significant correlation (p < 0.5. None of the subjective traits was correlated with total acceptance. Under theoretical criteria, tender Red Brangus beef cuts are infrequent; however the beef has a good acceptance. Characterization studies may be necessary and useful to create marketing niches specific for this and other cattle breeds.

Josef Holoubek

2015-01-01

Full Text Available Since 2010, the Czech State Forest Enterprise has been inviting timber-harvesting tenders while insisting on the forestry company purchasing the timber from the felled trees as well. To win, a tender must offer the greatest difference between the price of the timber purchased and the cost of the operations. Thus, the forest companies are now facing new problem: apart from minimizing the logging costs they are searching for a cross-cutting and mill-distribution strategy that maximizes the selling price of the harvested timber. The optimization model devised by the present paper provides support for finding an optimal timber selling strategy and, as an important contribution, include a detailed plan for cross-cutting the logs and assign them to the particular customers. We keep the support accessible via common office software and the cross-cutting and customer-assigning problem is formulated as a linear programming model for EXCEL, a particular real-world problem is solved and, using expert comparison, the model appears to provide very good results.

Constructive processes in person cognition.

Science.gov (United States)

Fiedler, K

1993-12-01

The notion of constructive memory processes is imported from research on eyewitness memory to the area of social cognition. Mere questioning about the applicability of personality attributes to a target person is shown to affect subsequent memory-based judgements of that person. These constructive influences are to be distinguished, conceptually, from the global notion of priming effects. In Expt 1, the target person was first described as an extravert; afterwards, subjects had to indicate whether either desirable aspects of extraversion (self-confidence) or undesirable aspects (exhibitionism) apply to the target or not. Mere questioning resulted in a congruent judgment bias towards the questioned attributes that did not generalize to a global halo effect. Experiment 2 replicated the basic finding and demonstrated that this phenomenon is independent of a generation effect (i.e. the memory advantage of self-generated inferences). These results are interpreted in terms of (a) a reframing of the categorical distribution representing the information about the target person in memory and (b) a regressive tendency to assume intermediate default values rather than extreme values for questioned attributes under uncertainty. Alternative explanations in terms of demand effects or a conformation bias cannot provide sufficient accounts. The relevance of constructive processes to understanding self-fulfilling prophecies and other phenomena in social interaction is discussed.

Effect of radiation processing on meat tenderisation

International Nuclear Information System (INIS)

Kanatt, Sweetie R.; Chawla, S.P.; Sharma, Arun

2015-01-01

The effect of radiation processing (0, 2.5, 5 and 10 kGy) on the tenderness of three types of popularly consumed meat in India namely chicken, lamb and buffalo was investigated. In irradiated meat samples dose dependant reduction in water holding capacity, cooking yield and shear force was observed. Reduction in shear force upon radiation processing was more pronounced in buffalo meat. Protein and collagen solubility as well as TCA soluble protein content increased on irradiation. Radiation processing of meat samples resulted in some change in colour of meat. Results suggested that irradiation leads to dose dependant tenderization of meat. Radiation processing of meat at a dose of 2.5 kGy improved its texture and had acceptable odour. - Highlights: • Effect of radiation processing on tenderness of three meat systems was evaluated. • Dose dependant reduction in shear force seen in buffalo meat. • Collagen solubility increased with irradiation

The influence of low temperature, type of muscle and electrical stimulation on the course of rigor mortis, ageing and tenderness of beef muscles.

Science.gov (United States)

Olsson, U; Hertzman, C; Tornberg, E

1994-01-01

The course of rigor mortis, ageing and tenderness have been evaluated for two beef muscles, M. semimembranosus (SM) and M. longissimus dorsi (LD), when entering rigor at constant temperatures in the cold-shortening region (1, 4, 7 and 10°C). The influence of electrical stimulation (ES) was also examined. Post-mortem changes were registered by shortening and isometric tension and by following the decline of pH, ATP and creatine phosphate. The effect of ageing on tenderness was recorded by measuring shear-force (2, 8 and 15 days post mortem) and the sensory properties were assessed 15 days post mortem. It was found that shortening increased with decreasing temperature, resulting in decreased tenderness. Tenderness for LD, but not for SM, was improved by ES at 1 and 4°C, whereas ES did not give rise to any decrease in the degree of shortening during rigor mortis development. This suggests that ES influences tenderization more than it prevents cold-shortening. The samples with a pre-rigor mortis temperature of 1°C could not be tenderized, when stored up to 15 days, whereas this was the case for the muscles entering rigor mortis at the other higher temperatures. The results show that under the conditions used in this study, the course of rigor mortis is more important for the ultimate tenderness than the course of ageing. Copyright © 1994.

Government space agencies, including NASA and ESA, are conducting preliminary studies on building alternative space-habitat systems for deep-space exploration. Such studies include development of advanced technologies for planetary surface exploration, including an in-depth understanding of the use of local resources. Currently, NASA plans to land humans on Mars in the 2030s. Similarly, other space agencies from Europe (ESA), Canada (CSA), Russia (Roscosmos), India (ISRO), Japan (JAXA) and China (CNSA) have already initiated or announced their plans for launching a series of lunar missions over the next decade, ranging from orbiters, landers and rovers for extended stays on the lunar surface. As the Space Odyssey is one of humanity's oldest dreams, there has been a series of research works for establishing temporary or permanent settlement on other planetary bodies, including the Moon and Mars. This paper reviews current projects developing extra-terrestrial construction, broadly categorised as: (i) ISRU-based construction materials; (ii) fabrication methods; and (iii) construction processes. It also discusses four categories of challenges to developing an appropriate construction process: (i) lunar simulants; (ii) material fabrication and curing; (iii) microwave-sintering based fabrication; and (iv) fully autonomous and scaled-up construction processes.

2012-01-01

The objective of our study was to determine effect of packaging method and storage time on reducing Listeria monocytogenes in shelf-stable meat snacks. Commercially available kippered beef steak strips and turkey tenders were dipped into a 5-strain L. monocytogenes cocktail, and dried at 23 °C until a water activity of 0.80 was achieved. Inoculated samples were packaged with 4 treatments: (1) vacuum, (2) nitrogen flushed with oxygen scavenger, (3) heat sealed with oxygen scavenger, and (4) heat sealed without oxygen scavenger. Samples were stored at 23 °C and evaluated for L. monocytogenes levels at 0, 24, 48, and 72 h. Initial levels (time 0) of L. monocytogenes were approximately 5.7 log CFU/cm² for steak and tenders. After 24 h of storage time, a 1 log CFU/cm² reduction of L. monocytogenes was observed for turkey tenders for all packaging treatments. After 48 h, turkey tenders showed >1 log CFU/cm² reduction of L. monocytogenes for all packaging treatments except for vacuum, where only 0.9 log CFU/cm² reduction was observed. After 72 h, reductions for all packaging treatments for turkey tenders ranged from 1.5 to 2.4 log CFU/cm². For kippered beef steak, there was no interaction between the packaging treatments and all storage times (P > 0.05) whereas, time was different (P packaging treatments and a 2.1 log CFU/ cm² L. monocytogenes reduction at 72 h of storage time. Processors of kippered beef steak and turkey tenders could use a combination of vacuum or nitrogen-flushing or heat sealed with an oxygen scavenger packaging methods and a holding time of 24 h prior to shipping to reduce potential L. monocytogenes numbers by ≥1 log. However, processors should be encouraged to hold packaged product a minimum of 72 h to enhance the margin of safety for L. monocytogenes control. © 2011 Institute of Food Technologists®

Risk Factors Influencing Construction Procurement Performance in Nigeria

2015-08-01

Full Text Available One of the challenges facing construction procurement performance is the failure to determine the risk related factors limiting its success. These risk factors can cause a significant increase in the procurement cost leading to an increase in the overall project cost. The purpose of this study is to identify and evaluate the risk factors influencing construction procurement performance with a view to achieve the overall project performance. The objectives are to establish a relative significance index score for the most important risk factors limiting the procurement performance of the projects. A self administered questionnaire was employed to the construction industry professionals for responses. A total of 78 questionnaires were distributed to these professionals (architects, quantity surveyors, engineers, and contractors but 62 were returned and analyzed using influential index and later ranked in order of importance. Results of the analysis indicate a disparity in terms of ranking of the factors influencing construction procurement performance. Corruption related risk, conflict of interest, ineffective project technical feasibility, and lack of commitment to transparency were found to be the most significant factors limiting construction procurement performance. Communication barriers and unconfidential tender evaluation process were found to be the low weighted risk factors. The findings can serve as a supportive mechanism for risks management in public construction procurement management. Therefore, construction procurement personnel at all levels of government may find this study relevant, while improving construction procurement performance in the country. It is recommended that construction procurement system should be focused on risks related to corruption, conflict of interest, and effective technical feasibility for improving the overall project performance.

Fine-mapping of a QTL influencing pork tenderness on porcine chromosome 2

Beever Jonathan E

2007-10-01

Full Text Available Abstract Background In a previous study, a quantitative trait locus (QTL exhibiting large effects on both Instron shear force and taste panel tenderness was detected within the Illinois Meat Quality Pedigree (IMQP. This QTL mapped to the q arm of porcine chromosome 2 (SSC2q. Comparative analysis of SSC2q indicates that it is orthologous to a segment of human chromosome 5 (HSA5 containing a strong positional candidate gene, calpastatin (CAST. CAST polymorphisms have recently been shown to be associated with meat quality characteristics; however, the possible involvement of other genes and/or molecular variation in this region cannot be excluded, thus requiring fine-mapping of the QTL. Results Recent advances in porcine genome resources, including high-resolution radiation hybrid and bacterial artificial chromosome (BAC physical maps, were utilized for development of novel informative markers. Marker density in the ~30-Mb region surrounding the most likely QTL position was increased by addition of eighteen new microsatellite markers, including nine publicly-available and nine novel markers. Two newly-developed markers were derived from a porcine BAC clone containing the CAST gene. Refinement of the QTL position was achieved through linkage and haplotype analyses. Within-family linkage analyses revealed at least two families segregating for a highly-significant QTL in strong positional agreement with CAST markers. A combined analysis of these two families yielded QTL intervals of 36 cM and 7 cM for Instron shear force and taste panel tenderness, respectively, while haplotype analyses suggested further refinement to a 1.8 cM interval containing CAST markers. The presence of additional tenderness QTL on SSC2q was also suggested. Conclusion These results reinforce CAST as a strong positional candidate. Further analysis of CAST molecular variation within the IMQP F1 boars should enhance understanding of the molecular basis of pork tenderness, and thus

Full Text Available The article analyses environmental and ecological criteria of selecting the most beneficial offer in the aspect of LCC. Construction works contracts and the potential method of defining the above criteria, among others, is pondered on (for example by the recommendation of a material, which is supposed to be used, a ban on substances that are harmful for human health as well for the environment. In the relation to the above, it is necessary to define technical parameters that have an impact on the environment, for example the level of pollution and noise emission, electricity and water consumption, or stating the minimal involvement of a processed ingredient. In addition the article presents also an account of the life cycle cost of a building from the point of view of environmental criteria constituting an element of selecting the most beneficial offer in the area of competitive tendering.

Local sensitization to noxious stimuli has been previously described in acute whiplash injury and has been suggested to be a risk factor for chronic sequelae following acute whiplash injury. In this study, we prospectively examined the development of tender points and mechano-sensitivity in 157 acute whiplash injured patients, who fulfilled criteria for WAD grade 2 (n=153) or grade 3 (n=4) seen about 5 days after injury (4.8+/-2.3) and who subsequently had or had not recovered 1 year after a cervical sprain. Tender point scores and stimulus-response function for mechanical pressure were determined in injured and non-injured body regions at specific time-points after injury. Thirty-six of 157 WAD grade 2 patients (22.9%) had not recovered, defined as reduced work capacity after 1 year. Non-recovered patients had higher total tender point scores after 12 (pwhiplash injury and the development of further sensitization in patients with long-term disability.

Making the link: climate policy and the reform of the UK construction industry

International Nuclear Information System (INIS)

Sorrell, Steve

2003-01-01

This paper explores the barriers to energy efficiency in the construction of non-domestic buildings in the UK. The source of the barriers is argued to lie in the organisation of the construction industry, including the linear design process, the reliance on cost-based competitive tendering and the incentives placed upon different actors. The consequences include oversizing of equipment, reduced quality, neglect of whole life costs and lack of integrated design. Each of these problems can usefully be interpreted using concepts from the new institutional economics. While the barriers are well known to construction industry specialists, they are relatively neglected in the academic literature on energy policy. Furthermore, conventional policy measures such as building regulations leave these barriers largely untouched. The UK construction industry is currently undergoing a series of reforms which aim to change the relationship between different actors and to achieve improvements in product quality and productivity. While these reforms have the potential to address many of the barriers, the reform agenda makes practically no reference to sustainability. This paper argues that climate policy objectives must be integrated into the reform agenda if the UK is to begin the transition to a low carbon built environment

Constructal theory through thermodynamics of irreversible processes framework

International Nuclear Information System (INIS)

Tescari, S.; Mazet, N.; Neveu, P.

2011-01-01

Highlights: → Point to area flow problem is solved through Thermodynamics of irreversible processes. → A new optimisation criterion is defined: the exergy or entropy impedance. → Optimisation is performed following two different routes, constructal or global. → Global optimisation is more efficient than constructal optimisation. → Global optimisation enhances the domain of construct benefits. - Abstract: Point to volume flow problem is revisited on a thermodynamics of irreversible processes (TIP) basis. The first step consists in evaluating the local entropy production of the system, and deducing from this expression the phenomenological laws. Then, the total entropy production can be simply evaluated. It is demonstrated that total entropy production can be written in a remarkable form: the product of the so-called entropy impedance with the square of the heat flux. As the heat flux is given, optimisation consists in minimising the entropy impedance. It is also shown that minimising entropy impedance minimises the maximum temperature difference. Applied to the elemental volume, this optimisation process leads to a shape factor close to the one already published. For the first construction, the equivalent system is defined as stated by Prigogine: when subjected to the same constraints, two systems are thermodynamically equivalent if their entropy production is equal. Two optimisation routes are then investigated: a global optimisation where all scales are taken into account and the constructal optimisation where the system is optimised scale by scale. In this second case, results are close to Ghodossi's work. When global optimisation is performed, it is demonstrated that conductive paths have to be spread uniformly in the active material (i.e. the number of elemental volumes must go to infinite). Comparing the two routes, global optimisation leads to better performance than constructal optimisation. Moreover, global optimisation enlarges the domain of

A Study of Construction Reactor Oversight Process in US

2015-01-01

This process provides a risk-informed approach such as construction significance determination process (SDP) and construction program performance index analogous to those used in the Reactor Oversight Process (ROP). The cROP has been applied to Vogtle units 3, 4 and V.C. Summer units 2, 3 under construction for the regulatory inspection. In this paper, the cROP is dissected to present its major contents and characteristics. The main features of the cROP can be summarized as followings: 1) The cROP which adopts the concept of the ROP used for operating NPPs assesses NPP under construction periodically to determine the appropriate level of regulatory response. 2) The cROP consists of three parts: the CIP, the CAP and the CEP. 3) The inspections for NPPs under construction can be categorized into three parts: vendor inspection, baseline inspection and supplemental and plant specific inspections. USNRC's regulatory resources can be used effectively based on baseline inspection, which is using ITAAC inspections. The construction SDP is used to assign the color scheme to categorize the significance of inspection findings. Regulatory actions are taken from CAM to which the significance of inspection findings input. In this paper, major contents and characteristics of USNRC's cROP have been presented

Joint involvement in patients affected by systemic lupus erythematosus: application of the swollen to tender joint count ratio

2015-09-01

Full Text Available Joint involvement is a common manifestation in systemic lupus erythematosus (SLE. According to the SLE disease activity index 2000 (SLEDAI-2K, joint involvement is present in case of ≥2 joints with pain and signs of inflammation. However this definition could fail to catch all the various features of joint involvement. Alternatively the Swollen to Tender joint Ratio (STR could be used. This new index, which was originally proposed for rheumatoid arthritis (RA patients, is based on the count of 28 swollen and tender joints. Our study is, therefore, aimed to assess joint involvement in a SLE cohort using the STR. SLE patients with joint symptoms (≥1 tender joint were enrolled over a period of one month. Disease activity was assessed by SLEDAI-2K. We performed the swollen and tender joint count (0-28 and calculated the STR. Depending on the STR, SLE patients were grouped into three categories of disease activity: low (STR1.0. We also calculated the disease activity score based on a 28-joint count and the erythrocyte sedimentation rate (DAS28-ESR. We enrolled 100 SLE patients [F/M 95/5, mean±standard deviation (SD age 46.3±10.6 years, mean±SD disease duration 147.1±103.8 months]. The median of tender and swollen joints was 4 (IQR 7 and 1 (IQR 2.5, respectively. The median STR value was 0.03 (IQR 0.6. According to the STR, disease activity was low in 70 patients, moderate in 23 and high in 7. A significant correlation was identified between STR values and DAS28 (r=0.33, p=0.001. The present study suggests a correlation between STR and DAS28, allowing an easier and faster assessment of joint involvement with the former index.

Korea nuclear exports: Why did the Koreans win the UAE tender? Will Korea achieve its goal of exporting 80 nuclear reactors by 2030?

International Nuclear Information System (INIS)

Berthelemy, Michel; Leveque, Francois

2011-01-01

The success of Korea in winning, in December 2009, a USD 18.6 billion nuclear tender in the United Arab Emirates (UAE) has led to a growing interest in the organization and strengths of the Korean nuclear industry. In this paper, we present the main economic and political factors that explain the success of the Korean consortium. In particular, thanks to an active national program of Nuclear Power Plant (NPP) construction, Korea has developed distinct competitive advantages in terms of low cost, high credibility and high performance. At the same time, due to the important barriers to enter into the nuclear export market in the UAE, Korea has had to sacrifice its profit margin and has benefited from a strong political support from its government through export financing. More importantly, Korea's success is also due to its alliance with Westinghouse and the support of the US diplomacy. Subsequently, we show that while Korea has recently experienced setbacks in nuclear tenders, it will most certainly try to win in the short run a second nuclear tender with another aggressive price. In the longer run, Korea could take a growing share of the international market for NPPs. However, the extent to which Korea can achieve its long term export target will depend upon its capacity to finance nuclear export through export credits and upon the development of its alliance with Westinghouse. It is important to note that this paper was written before the Fukushima nuclear disaster. The scale of the human and environmental consequences of this accident are still unknown, and will undoubtedly have short and long term consequences on nuclear safety requirements and public attitude toward nuclear energy, which will most certainly impact the outlooks for nuclear new-builds.

2016-01-01

Full Text Available Non-value-adding activities are pure waste during the construction process. However, most of the construction practitioner does not realise that most of the activities performed during the construction process add no value to their project. A total of 375 numbers of questionnaires distributed to the Developer, Jabatan Kerja Raya, Consultants and Contractors. The study found that awareness by construction participants in Malaysia to take actions against non-value-adding activities during the construction process is relatively low. Through analysed by using the Pareto Chart, it has been found that defects and waiting time are two categories of non-value-adding activities that need to be prioritised by the industry. It is also found that non-value-adding activities most frequently occurred during structural and architectural work. This paper also reviewed on the causes of non-value-adding activities and discussed its effect towards time, cost, quality and productivity of the construction project. This paper is also important to give clearness and broader understandings on this form of waste other than material waste.

The role of internal and external constructive processes in evolution

2014-01-01

The architects of the Modern Synthesis viewed development as an unfolding of a form already latent in the genes. However, developing organisms play a far more active, constructive role in both their own development and their evolution than the Modern Synthesis proclaims. Here we outline what is meant by constructive processes in development and evolution, emphasizing how constructive development is a shared feature of many of the research developments central to the developing Extended Evolutionary Synthesis. Our article draws out the parallels between constructive physiological processes expressed internally and in the external environment (niche construction), showing how in each case they play important and not fully recognized evolutionary roles by modifying and biasing natural selection.

A Constructive Sharp Approach to Functional Quantization of Stochastic Processes

OpenAIRE

Junglen, Stefan; Luschgy, Harald

2010-01-01

We present a constructive approach to the functional quantization problem of stochastic processes, with an emphasis on Gaussian processes. The approach is constructive, since we reduce the infinite-dimensional functional quantization problem to a finite-dimensional quantization problem that can be solved numerically. Our approach achieves the sharp rate of the minimal quantization error and can be used to quantize the path space for Gaussian processes and also, for example, Lévy processes.

Technical note: use of belt grill cookery and slice shear force for assessment of pork longissimus tenderness.

Shackelford, S D; Wheeler, T L; Koohmaraie, M

2004-01-01

The present experiments were conducted to determine whether improved beef longissimus shear force methodology could be used to assess pork longissimus tenderness. Specifically, three experiments were conducted to: 1) determine the effect of belt grill (BG) cookery on repeatability of pork longissimus Warner-Bratzler shear force (WBSF), 2) compare the correlation of WBSF and slice shear force (SSF) with trained sensory panel tenderness ratings, and 3) estimate the repeatability of pork longissimus SSF for chops cooked with a BG. In Exp. 1 and 2, the longissimus was removed from the left side of each carcass (Exp. 1, n = 25; Exp. 2, n = 23) at 1 d postmortem and immediately frozen to maximize variation in tenderness. In Exp. 1, chops were cooked with either open-hearth electric broilers (OH) or BG, and WBSF was measured. Percentage of cooking loss was lower (P cooked with a BG (23.2%; SD = 1.7%) vs. OH (27.6%; SD = 3.0%). Estimates of the repeatability of WBSF were similar for chops cooked with OH (0.61) and BG (0.59). Although significant (P cooking methods accounted for less than 5% of the total variation in WBSF. In Exp. 2, the correlation of SSF (r = -0.72; P cooked with BG, and SSF was determined. The repeatability of SSF was 0.90, which is comparable to repeatability estimates for beef and lamb. Use of BG cookery and SSF could facilitate the collection of accurate pork longissimus tenderness data. Time and labor savings associated with BG cookery and the SSF technique should help to decrease research costs.

From queen to mother: motherhood as discursive construction in the seventeenth century neogranadine painting

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available This article examines motherhood as a discursive construction, linking this construction with the neogranadine visual discourse of the seventeenth century. The image of “The Virgin with the Child”, within the post Tridentine context, stood as a place of origin of a discourse modeling the women behavior, giving specific roles in relation with their children. The tender, loving and protective mother with their children emerges in the visual discourse as a narrative truth that should be adopted by subjects in everyday behavior.

Survival of Escherichia coli O157:H7 in needle-tenderized dry cured Westphalian ham.

Science.gov (United States)

Graumann, Gary H; Holley, Richard A

2007-09-15

Westphalian ham is a dry cured, ready-to-eat product that is manufactured without a lethal heat treatment. Hams are preserved by a process that involves curing, fermenting, smoking and drying, which may take 3 months or more to complete. The process can be accelerated by tenderizing the meat with solid needles, to increase the rate of cure-salt diffusion throughout muscle tissues. In this study, intact hams were immersed in a solution containing a five strain cocktail of Escherichia coli O157:H7 at 8 log cfu/mL, to determine whether needle treatment before cure application would internalize organisms from the surface. In two trials, the survival of E. coli O157:H7 on external surfaces and within deep tissues after needle treatment was followed during the ripening of hams. The injured E. coli O157:H7 cells were recovered by plating samples on pre-poured Tryptic Soy Agar plates which were incubated for 3 to 4 h at 35 degrees C, overlaid with Sorbitol MacConkey Agar containing cefixime and tellurite and re-incubated at 35 degrees C for 48 to 72 h. Inoculated-injected hams initially carried E. coli O157:H7 at numbers of 7.3 and 4.6 log cfu/g E. coli O157:H7 on the surface and inside, respectively. After 112 d of ripening, which included 79 d of drying, no E. coli O157:H7 were detected at the surface of hams following enrichment, whereas in deep tissue the organism was recovered at numbers of 3.1 log cfu/g. The Westphalian ham ripening procedure evidently was not adequate to eliminate E. coli O157:H7 internalized by needle tenderization.

Imagining the future: evidence for a hippocampal contribution to constructive processing.

Gaesser, Brendan; Spreng, R Nathan; McLelland, Victoria C; Addis, Donna Rose; Schacter, Daniel L

2013-12-01

Imagining future events and remembering past events rely on a common core network, but several regions within this network--including the hippocampus--show increased activity for imagining future events compared to remembering past events. It remains unclear whether this hippocampal activity reflects processes related to the demands of constructing details retrieved across disparate episodic memories into coherent imaginary events, encoding these events into memory, novelty detection, or some combination of these processes. We manipulated the degree of constructive processing by comparing activity associated with the initial construction of an imagined scenario with the re-construction of an imagined scenario (imagine vs. re-imagine). After accounting for effects of novelty and subsequent memory, we found that a region in the hippocampus was preferentially activated for newly constructed imagined events compared with re-imagined events. Our results suggest that the hippocampus may support several distinct but related processes that are critical for imagining future events, and they also indicate that a particular region within posterior hippocampus may uniquely contribute to the construction of imagined future events.

Probabilistic prediction of expected ground condition and construction time and costs in road tunnels

Directory of Open Access Journals (Sweden)

A. Mahmoodzadeh

2016-10-01

Full Text Available Ground condition and construction (excavation and support time and costs are the key factors in decision-making during planning and design phases of a tunnel project. An innovative methodology for probabilistic estimation of ground condition and construction time and costs is proposed, which is an integration of the ground prediction approach based on Markov process, and the time and cost variance analysis based on Monte-Carlo (MC simulation. The former provides the probabilistic description of ground classification along tunnel alignment according to the geological information revealed from geological profile and boreholes. The latter provides the probabilistic description of the expected construction time and costs for each operation according to the survey feedbacks from experts. Then an engineering application to Hamro tunnel is presented to demonstrate how the ground condition and the construction time and costs are estimated in a probabilistic way. In most items, in order to estimate the data needed for this methodology, a number of questionnaires are distributed among the tunneling experts and finally the mean values of the respondents are applied. These facilitate both the owners and the contractors to be aware of the risk that they should carry before construction, and are useful for both tendering and bidding.

Adenosine 5'-monophosphate (AMP) is often used in meat and poultry soups as a flavor enhancer (flavor modifier), or as food additives for specific nutritional purposes. Our previous research as well as evidence from others showed that actomyosin could be dissociated into myosin and actin by AMP in extracted muscle solution. However, there is no report available on the application of AMP to dissociate actomyosin and to improve meat tenderness. The objectives of this study were to evaluate the effect of AMP on duck meat tenderness and other quality traits and to explore the mechanism of the action of AMP on meat tenderness. Duck breast muscle was treated with 0, 10, 20, 30, 40 mmol L(-1) AMP at 5 °C for 10 h and examined for shear force, microstructure, actomyosin dissociation, myofibril fragmentation index (MFI), pH, water content, cooking loss, CIE* color (L*, a*, b*), inosine monophosphate (IMP) and free amino acid (FAA) contents. Results showed that shear force, cooking loss, L* and b* of the muscles significantly decreased after AMP treatment (P 0.05), and muscle shrinkage in transverse and longitudinal directions were restrained after AMP treatment. The results suggest that AMP could notably improve meat tenderness, and this effect was probably mainly through increasing muscle pH, promoting actomyosin dissociation and disrupting the Z-line; meanwhile, the conversion of AMP to IMP may contribute to the flavor of meat. © 2015 Society of Chemical Industry.

The costs associated with patients discharged with isolated clinician-elicited persistent midline tenderness and negative computed tomography (CT) findings have not been reported. Our aim was to determine the association of acute and post-acute patient and injury characteristics with health resource costs in such patients following road trauma. In a prospective cohort study, road trauma patients presenting with isolated persistent midline cervical tenderness and negative CT, who underwent additional acute imaging with MRI, were recruited. Patients were reviewed in the outpatient spine clinic following discharge, and were followed up at 6 and 12 months post-trauma. Multivariate linear regression was used to assess the association of injury mechanism, clinical assessment, socioeconomic factors and outcome findings with health resource costs generated in the acute hospital and post-acute periods. There were 64 patients recruited, of whom 24 (38%) had cervical spine injury detected on MRI. Of these, 2 patients were managed operatively, 6 were treated in cervical collars and 16 had the cervical spine cleared and were discharged. At 12 months, there were 25 patients (44%) with residual neck pain, and 22 (39%) with neck-related disability. The mean total cost was AUD $10,153 (SD=10,791) and the median was $4015 (IQR: 3044-6709). Transient neurologic deficit, which fully resolved early in the emergency department, was independently associated with higher marginal mean acute costs (represented in the analysis by the β coefficient) by $3521 (95% CI: 50-6880). Low education standard (β coefficient: $5988, 95% CI: 822-13,317), neck pain at 6 months (β coefficient: $4017, 95% CI: 426-9254) and history of transient neurologic deficit (β coefficient: $8471, 95% CI: 1766-18,334) were associated with increased post-acute costs. In a homogeneous group of road trauma patients with non fracture-related persistent midline cervical tenderness, health resource costs varied

To compare the masticatory and cervical muscle tenderness and pain sensitivity in the hand (remote region) between patients with temporomandibular disorders (TMD) and healthy controls. Twenty female subjects were diagnosed with chronic TMD, and 20 were considered healthy. Subjects completed the Neck Disability Index and Limitations of Daily Functions in a TMD questionnaire. Tenderness of the masticatory and cervical muscles and pain sensitivity in the hand were measured using an algometer. Three-way mixed analysis of variance (ANOVA) evaluated differences in muscle tenderness between groups. One-way ANOVA compared pain sensitivity in the hand between groups. Effect sizes were assessed using Cohen guidelines. Significantly increased masticatory and cervical muscle tenderness and pain sensitivity in the hand were found in subjects with TMD when compared with healthy subjects. Moderate to high effect sizes showed the clinical relevance of the findings. The results of this study have highlighted the importance of assessing TMD patients not only in the craniofacial region but also in the neck and other parts of the body. Future studies should focus on testing the effectiveness of treatments addressing the neck and the pain sensitivity in the hand in patients with TMD.

Full Text Available Models to analyse and calculate the costs of prevention in the construction industry are not easy to apply in this area. Firstly, because they are based on studies carried out in the manufacturing sector; and secondly because the traditional models for analyzing these costs are limited to identifying and classifying them. This calculation models need to be improved. Hence this study is an attempt to fill the gap by develops a safety and health cost framework from pre-construction stage until to construction stage in order to assist client to allow the compliance of safety aspects in a tender document can be assured. A mixed method research will be used in this study. Semi structured interview and content analysis will be used as a main tool for the data collection. Then, the questionnaire will be distributed to the expertise in construction industry.

Full Text Available One of the key areas being emphasis in ISO 9001 Quality Management System (QMS is performance measurement towards continual improvement. Among the primary measuring tools is quality cost approach. Quality cost has been well practice in manufacturing sector but slowly gain its importance in construction industry. In fact Project Management Body of Knowledge (PMBOK has reckoned quality cost as one of the tool and technique in few of its management processes. In view of such circumstances that has prompted an effort to undertake a study to ascertain the level of knowledge and practice on quality cost in Malaysian construction landscape. The targeted group of respondents was the personnel in the project management team. Capitalizing Construction Industry Development Board (CIDB National Electronic Tendering Initiatives (NETI road shows which were held in year 2007 throughout the country, the author was able to garner 263 respondents representing the project management team. Subsequently the data gathered from the completed forms were analyzed using Statistical Package for Social Science (SPSS software. General findings indicated that the level of knowledge and practice on quality cost among the project management team were relatively low. One of the main contributing factors was poor knowledge in the area related to quality cost. Despite of such scenario most of the respondents showed their interest in acquiring knowledge in the field of quality cost. Hence quality cost approach is at the infancy stage in Malaysian construction industry.

CONTRACTUAL RISKS IN THE NEW ZEALAND CONSTRUCTION INDUSTRY: ANALYSIS AND MITIGATION MEASURES

Directory of Open Access Journals (Sweden)

Jasper Mbachu

2014-12-01

Full Text Available While tendering for jobs, a contractor is expected to analyse the various risks in each prospective project and price them appropriately. Contingencies are included in the tender price to cater for the various risks based on their impacts on the project targets and profit margin. Currently in New Zealand (NZ, there is little or no information on the various contractual risks and their mitigation measures. This has led to contractors over compensating or under compensating for risks with costly consequences. This study aimed to establish priority contractual risks in the NZ construction industry, and their mitigation measures. The research was based on a questionnaire survey of consultants and contractors. Descriptive statistics and multi-attribute techniques were used in the data analysis. Results showed 21 risk factors which were segregated into 6 broad categories in diminishing levels of significance as follows: Site conditions, main contractor, pricing, subcontractor, external and client- related risks. Putting tags and conditions to risky price items in the tender bids, and transferring the risks onto other parties were analysed as the 2 most effective out of the 5 key risk mitigation measures identified. Being cautious of the priority risks and application of the identified effective risk mitigation measures could guide contractors and the project team to more appropriately budget for and respond to risks, thereby ensuring more satisfactory project outcomes.

Kanatt, Sweetie R.; Chawla, S. P.; Sharma, Arun

2015-06-01

The effect of radiation processing (0, 2.5, 5 and 10 kGy) on the tenderness of three types of popularly consumed meat in India namely chicken, lamb and buffalo was investigated. In irradiated meat samples dose dependant reduction in water holding capacity, cooking yield and shear force was observed. Reduction in shear force upon radiation processing was more pronounced in buffalo meat. Protein and collagen solubility as well as TCA soluble protein content increased on irradiation. Radiation processing of meat samples resulted in some change in colour of meat. Results suggested that irradiation leads to dose dependant tenderization of meat. Radiation processing of meat at a dose of 2.5 kGy improved its texture and had acceptable odour.

Regulatory polymorphisms in the bovine Ankyrin 1 gene promoter are associated with tenderness and intramuscular fat content

2010-12-01

Full Text Available Abstract Background Recent QTL and gene expression studies have highlighted ankyrins as positional and functional candidate genes for meat quality. Our objective was to characterise the promoter region of the bovine ankyrin 1 gene and to test polymorphisms for association with sensory and technological meat quality measures. Results Seven novel promoter SNPs were identified in a 1.11 kb region of the ankyrin 1 promoter in Angus, Charolais and Limousin bulls (n = 15 per breed as well as 141 crossbred beef animals for which meat quality data was available. Eighteen haplotypes were inferred with significant breed variation in haplotype frequencies. The five most frequent SNPs and the four most frequent haplotypes were subsequently tested for association with sensory and technological measures of meat quality in the crossbred population. SNP1, SNP3 and SNP4 (which were subsequently designated regulatory SNPs and SNP5 were associated with traits that contribute to sensorial and technological measurements of tenderness and texture; Haplotype 1 and haplotype 4 were oppositely correlated with traits contributing to tenderness (P Conclusion The conclusion from this study is that alleles defining haplotypes 2 and 4 could usefully contribute to marker SNP panels used to select individuals with improved IMF/juiciness or tenderness in a genome-assisted selection framework.

Oakhill, J

1982-02-01

An experiment was carried out to investigate seven-eight-year-old children's memory for aurally presented sentences. A recognition-memory task was used to probe constructive memory processes in two groups differentiated by their ability at comprehending printed text. The recognition errors of both groups indicated that they constructed meanings implied by the original input sentences, whilst demonstrating poor memory for the syntactic form of the sentences. The tendency to construct meanings implied by the original input sentences was greater in children who scored higher on tests of reading comprehension of test. These results indicate that constructive memory processes are related to comprehension ability in young readers.

The method for estimating the interest of each participator of the intensing process and developing the optimal solution, that is capable to approach these interests, is suggested. The conclusion is made that it is necessary to develop and confirm the branch standard, which should include a complex amalgamated network of works to improve the organization of the investing process

Variation at the Calpain 3 gene is associated with meat tenderness in zebu and composite breeds of cattle

Directory of Open Access Journals (Sweden)

Bunch Rowan J

2008-07-01

Full Text Available Abstract Background Quantitative Trait Loci (QTL affecting meat tenderness have been reported on Bovine chromosome 10. Here we examine variation at the Calpain 3 (CAPN3 gene in cattle, a gene located within the confidence interval of the QTL, and which is a positional candidate gene based on the biochemical activity of the protein. Results We identified single nucleotide polymorphisms (SNP in the genomic sequence of the CAPN3 gene and tested three of these in a sample of 2189 cattle. Of the three SNP genotyped, the CAPN3:c.1538+225G>T had the largest significant additive effect, with an allele substitution effect in the Brahman of α = -0.144 kg, SE = 0.060, P = 0.016, and the polymorphism explained 1.7% of the residual phenotypic variance in that sample of the breed. Significant haplotype substitution effects were found for all three breeds, the Brahman, the Belmont Red, and the Santa Gertrudis. For the common haplotype, the haplotype substitution effect in the Brahman was α = 0.169 kg, SE = 0.056, P = 0.003. The effect of this gene was compared to Calpastatin in the same sample. The SNP show negligible frequencies in taurine breeds and low to moderate minor allele frequencies in zebu or composite animals. Conclusion These associations confirm the location of a QTL for meat tenderness in this region of bovine chromosome 10. SNP in or near this gene may be responsible for part of the overall difference between taurine and zebu breeds in meat tenderness, and the greater variability in meat tenderness found in zebu and composite breeds. The evidence provided so far suggests that none of these tested SNP are causative mutations.

Full Text Available The focus of the study is on the knowledge that is constructed through perceptual processes during craft making in the context of the Finnish Basic Education in the Arts (BEA system. Craft studies in the BEA are defined as craft-art. The research method used is the grounded theory. The data consists of seven interviews and participant observations. Participants in the study are adolescents who study craft-art in the BEA system in Visual Art School, Aimo in Hämeenlinna. The aim of the article is to present, define and reflect on the concepts, properties and dimensions concerning perceptual processes that are discovered in this stage of the study following grounded theory procedures. The perceptual processes are an essential means of constructing knowledge in craft-art. Consequently, one aim of the study is to discuss how these processes are connected to various types of knowledge. The perceptual processes are described by seven concepts: imitative, anticipative, evaluative, experimental, emotional, temporal and bodily perceptions. They indicate on a conceptual level the characteristic of knowledge constructed through perceptual processes in craft-art. Further, theconcepts have several properties that can vary dimensionally between two qualities. The properties are activity, function and position. The dimensions of the properties vary from active to passive, formal to informal and internal to external. In conclusion, the concepts can describe a large range of incidents in different situations. They also seem to describe well the practice of  craft-art and there are several connections with pre-existing concepts of knowledge.Keywords: Craft, Knowledge, Perceptual process, Basic Education in the Arts, Grounded Theory

Pande, Shubhra; Srinivasan, Krishnapura

2013-10-01

The antioxidant role of tender cluster beans (Cyamopsis tetragonoloba, CB), a rich source of soluble fibre, was investigated in a hypercholesterolemia-induced oxidative stress situation in rats. In the context of dietary garlic (Allium sativa) potentiating the hypocholesterolemic influence of CB, we also examined if dietary garlic enhances the antioxidant potential of CB. Groups of Wistar rats were rendered hypercholesterolemic by feeding them a 0.5% cholesterol diet for 8 weeks. Dietary interventions were made by inclusion of 15% tender CB powder or 1% garlic powder or their combination in a high-cholesterol diet. Concentrations of antioxidant molecules and activities of antioxidant enzymes in blood and liver were examined. Dietary CB displayed an antioxidant influence in terms of elevating ascorbic acid and glutathione concentrations and stimulating the activities of antioxidant enzymes both in blood and liver. The antioxidant effect of dietary CB was generally potentiated by co-administration of garlic. Thus, consumption of tender CB and garlic together could form a strategy for improving the body's antioxidant status.

We examined the relationship between body mass index (BMI) and measures of tenderness, quality of life, and physical functioning in female fibromyalgia (FMS) patients. A random sample of 100 female FMS patients from a database of 550 FMS individuals was interviewed and assessed according to a structured questionnaire that included FMS-related symptoms, measures of tenderness (point count and dolorimetry), quality of life (SF-36), physical functioning, and BMI. Weight was defined as normal, overweight, and obesity according to BMI. Twenty-seven percent of the FMS patients had normal BMI, 28% were overweight, and 45% were obese. BMI was negatively correlated with quality of life (r = -0.205, P = 0.044) and tenderness threshold (r = -0.238, P = 0.021) and positively correlated with physical dysfunctioning (r = 0.202, P = 0.047) and point count (r = 0.261, P = 0.011). Obese FMS patients display higher pain sensitivity and lower levels of quality of life. In designing studies that explore factors affecting tenderness, BMI should be included in addition to sex, age, etc.

Simulation of the honeycomb construction process

2010-01-01

The construction process of the honeycomb by bees is an astonishing process. The original structure which the bees built is nothing more than a lot of rough cylinders. But keeping the beeswax semi-flow for a certain time, those rough structures become perfect hexahedral columns. A modified, simplified particle method was used here to simulate the semi-flow state of the material. Although the parameters used here were still rather subjective, the simulation still could demonstrate some behavior of that sort of material like beeswax. And the method that the bees used to build their honey comb, could be an efficient method to imitate when we are trying to manufacture cellular materials.

The study aimed to determine the effects of a 4-month Tai Chi intervention on tenderness, functional capacity, symptomatology, and quality of life in men with fibromyalgia. The effect of a 3-month detraining period was also analyzed. Six men with fibromyalgia (age 52.3 ± 9.3 years) followed a 4-month Tai Chi intervention. The outcome variables were tenderness, functional capacity (30-second chair stand, handgrip strength, chair sit and reach, back scratch, blind flamingo, 8 feet up and go, and 6-minute walk tests), and self-administered questionnaires. A significant improvement (p = .028) after the intervention period for the chair sit and reach test was found, such improvement was maintained after the detraining phase. Tenderness, symptomatology, and quality of life did not significantly change after the intervention period or the detraining phase. In summary, a 4-month Tai Chi intervention improved lower body flexibility in men with fibromyalgia. This improvement persisted after the detraining period.

Serotonin (5-HT) mediates pain by peripheral 5-HT3-receptors. Results from a few studies indicate that intramuscular injections of 5-HT3-antagonists may reduce musculoskeletal pain. The aim of this study was to investigate if repeated intramuscular tender-point injections of the 5-HT3-antagonist granisetron alleviate pain in patients with myofascial temporomandibular disorders (M-TMD). This prospective, randomized, controlled, double blind, parallel-arm trial (RCT) was carried out during at two centers in Stockholm, Sweden. The randomization was performed by a researcher who did not participate in data collection with an internet-based application ( www.randomization.com ). 40 patients with a diagnose of M-TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were randomized to receive repeated injections, one week apart, with either granisetron (GRA; 3 mg) or isotonic saline as control (CTR). The median weekly pain intensities decreased significantly at all follow-ups (1-, 2-, 6-months) in the GRA-group (Friedman test; P  0.075). The numbers needed to treat (NNT) were 4 at the 1- and 6-month follow-ups, and 3.3 at the 2-month follow-up in favor of granisetron. Repeated intramuscular tender-point injections with granisetron provide a new pharmacological treatment possibility for myofascial pain patients with repeated intramuscular tender-point injections with the serotonin type 3 antagonist granisetron. It showed a clinically relevant pain reducing effect in the temporomandibular region, both in a short- and long-term aspect.

Based on single factor experiments, NaCl concentration, adenosine 5'-monophosphate (AMP) concentration and temperature were selected as independent variables for a three-level Box-Behnken experimental design, and the shear force and cooking loss were response values for regression analysis. According to the statistical models, it showed that all independent variables had significant effects on shear force and cooking loss, and optimal values were at the NaCl concentration of 4.15%, AMP concentration of 22.27 mmol/L and temperature of 16.70°C, which was determined with three-dimensional response surface diagrams and contour plots. Under this condition, the observed shear force and cooking loss were 0.625 kg and 8.07%, respectively, exhibiting a good agreement with their predicted values, showing the good applicability and feasibility of response surface methodology (RSM) for improving pork tenderness. Compared with control pig muscles, AMP combined with NaCl treatment demonstrated significant effects on improvement of meat tenderness and reduction of cooking loss. Therefore, AMP could be regarded as an effective tenderization agent for pork. © 2015 Japanese Society of Animal Science.

Full Text Available Small and medium sized companies (SMEs operating in the construction industry in regionalareas of Australia often struggle to compete against city-based companies for constructionwork. This paper identifies the barriers that confront SMEs in areas outsidemajor cities, specifically in regional areas of Victoria (Australia where local firms oftencompete unsuccessfully against large Melbourne-based organisations. The authors alsolook at the possibility of using e-commerce solutions to give regional SMEs greater competitivenessas well as considering possible policy initiatives that may assist these companiesto be more successful in tendering against city-based competition.

Gaussian processes and constructive scalar field theory

International Nuclear Information System (INIS)

Benfatto, G.; Nicolo, F.

1981-01-01

The last years have seen a very deep progress of constructive euclidean field theory, with many implications in the area of the random fields theory. The authors discuss an approach to super-renormalizable scalar field theories, which puts in particular evidence the connections with the theory of the Gaussian processes associated to the elliptic operators. The paper consists of two parts. Part I treats some problems in the theory of Gaussian processes which arise in the approach to the PHI 3 4 theory. Part II is devoted to the discussion of the ultraviolet stability in the PHI 3 4 theory. (Auth.)

As a result of this work, sample texts, so-called performance sheets, have been drawn up for the invitation to tender for IT devices. As a supplement to the standard technical requirements, such as computer performance, memory capacity, etc., these texts cover the aspects of energy efficiency. The performance sheets can be enclosed with the invitations to tender as an appendix, or be used directly as text modules. They are supplemented by explanatory texts, which give information regarding technical terms, labels and possible technical realizations. Performance sheets and explanatory texts are included in the appendix to this report. The goal of these activities is to exert pressure on the market, which should ultimately lead to more efficient units. In addition, however, these texts should serve to make the offices placing the invitations to tender more aware of the energy efficiency aspect. Energy saving functions are fairly common for PCs and monitors nowadays. Reference to proved technical realisations can be made in the performance sheets. The situation is more difficult for servers. Although some technical solutions have been initiated, very little is known about practical applications. Further activities are necessary here. (author)

Risk analysis in the management of urban construction projects from the perspective of the employer and the contractor

2015-12-01

Full Text Available Imbalance between anticipated and actual progress in the development of urban construction projects suggests that there are many obstacles and risks which not only causes the urban management be unsustainable, but the reconstruction and development of urban space is also seriously threatened. In this study, the library research on issues related to the risk of construction projects was done, then some interviews were conducted with experts and managers informed and involved in the projects, and finally questionnaires were distributed to identify and classify the impact of the risks of the implementation of the construction projects. After analyzing the data, the results indicated that the experts listed the most significant risks as the delays in the payment of contractors' claims and statements due to the lack of handling financial instruments, the governance of relationships rather than rules in the tenders resulting from employer actions, low commitment to the quality of work provided by their subcontractors, failure to complete the detail engineering by foreign contractors on time, weaknesses in contractors' financial resources, and offering lower prices than reasonable by contractors to win the tender. All of these require special attention and other kinds of risks are important at the next level. Finally, the solutions for eliminating or reducing risks in high-risk areas have been offered to provide tranquility for contractors and employers.

Modifying the home environments of older people as they age in place is a well-established health and social care intervention. Using design and construction methods to redress any imbalance caused by the ageing process or disability within the home environment, occupational therapists are seen as the experts in this field of practice. However, the process used by occupational therapists when modifying home environments has been criticised for being disorganised and not founded on theoretical principles and concepts underpinning the profession. To address this issue, research was conducted to develop a design and construction process protocol specifically for home modifications. A three-stage approach was taken for the analysis of qualitative data generated from an online survey, completed by 135 occupational therapists in the UK. Using both the existing occupational therapy intervention process model and the design and construction process protocol as the theoretical frameworks, a 4-phase, 9-subphase design and construction process protocol for home modifications was developed. Overall, the study is innovative in developing the first process protocol for home modifications, potentially providing occupational therapists with a systematic and effective approach to the design and delivery of home modification services for older and disabled people.

Bahamid, R. A.; Doh, S. I.

2017-11-01

In the construction industry, risk management concept is a less popular technique. There are three main stages in the systematic approach to risk management in construction industry. These stages include: a) risk response; b) risk analysis and evaluation; and c) risk identification. The high risk related to construction business affects each of its participants; while operational analysis and management of construction related risks remain an enormous task to practitioners of the industry. This paper tends towards reviewing the existing literature on construction project risk managements in developing countries specifically on risk management process. The literature lacks ample risk management process approach capable of capturing risk impact on diverse project objectives. This literature review aims at discovering the frequently used techniques in risk identification and analysis. It also attempts to identify response to clarifying the different classifications of risk sources in the existing literature of developing countries, and to identify the future research directions on project risks in the area of construction in developing countries.

Full Text Available Summary. Problem statement. Technogenic catastrophes, failures or natural calamities, result in destruction of build objects. Under the obstructions of destructions can be victims. The most widespread technogenic failure is explosions of gas. The structure of obstructions changes and depends on parameters and direction of explosion, firstly its size and location of wreckages. Sorting out of obstructions is carried out with machines and mechanisms which do not meet the requirements of these works, that predetermines of carrying out of rescue or restoration works on imperfect scheme , especially on the initial stages, and it increases terms and labour intensiveness of their conduct. Development technological solution is needed for the effective sorting out of destructions of construction objects. Purpose. Development of unification solution on the improvement of technological processes of sorting out of destructions of buildings and constructions. Conclusion. The analysis of experience of works shows on sorting out of the destroyed construction objects, show that they are carried out on imperfect scheme, which do not take into account character of destruction of objects and are based on the use of construction machines which do not meet the requirements of these processes, and lead to considerable resource losses. Developed unified scheme of sorting out of the destroyed construction objects depending on character of their destruction and possibility of line of works, and also with the use of build machines with a multipurpose equipment, provide the increase of efficiency of carrying out of rescue and construction works.

Reactor construction programme in Japan

NONE

1959-04-15

In September last year, the Japanese Government requested the International Atomic Energy Agency to supply three tons of natural uranium for a research reactor, and the Agency has now arranged for its sale to Japan. The metal will be supplied in ingot form and after fabrication it will be used as fuel in a reactor of the natural uranium, heavy water type. The uranium will be obtained from Canada and sold to Japan by IAEA. The Agency had invited tenders for its supply, and after considering the tenders received, the Agency's Board of Governors decided that the Canadian offer to the Agency of three tons of natural uranium free of charge should be accepted and that the selling price to Japan should be US $35. 50 per kilogramme. The price takes into account Article XIV/E of the Agency's Statute which says that the Agency shall establish a scale of charges (including those for storage and handling) for materials furnished to Member States, and that the scale shall be designed to produce revenues to meet expenses in connexion with materials acquired by the Agency and costs of materials and services provided by it under agreements with one or more members. This is the first operation of its kind to be undertaken by the Agency, and the reactor for which the supply is being made will be the first in Japan to be constructed by Japanese scientists and technicians. IAEA's Board of Governors has given the necessary approval to the reactor project for which the Agency is providing assistance

2018-01-01

In this study, edible films were produced from sodium caseinate and a sodium caseinate-starch mixture and with or without oleoresins (cumin and oregano oleoresin mixture). Chicken meat was wrapped in the respective films, stored at 4 ℃ for four days, and roasted at 200 ℃ for 30 min. The cooking loss, color changes, instrumental tenderness (shear force and energy) were measured. In addition, sensory evaluation was performed. All films effectively reduced cooking loss from chicken meat. The sodium caseinate-starch-based films were the most successful in preventing cooking loss. The average shear force and shear energy values of the wrapped samples were about 40% and 30% less than those of control samples, respectively. In sensory evaluation, chicken meat roasted after wrapping with the films was considered more tender and delicious than the control. Particularly, chicken meat wrapped with the films containing oleoresin mixture was assessed as the most delicious among the samples. It was shown that the cooking quality of the chicken meat could be significantly improved by pre-wrapping the meat with edible films.

2009-09-01

Wagyu-sired (n = 20) and Angus-sired (n = 19) steers and heifers were used to compare the effects of sire breed on feedlot performance, carcass characteristics, and meat tenderness. Calves were weaned at 138 +/- 5 d of age and individually fed a finishing diet consisting of 65% whole corn, 20% protein/vitamin/mineral supplement, and 15% corn silage on a DM basis. Heifers and steers were slaughtered at 535 and 560 kg of BW, respectively. Carcasses were ribbed between the 12th and 13th (USDA grading system) and the 6th and 7th ribs (Japanese grading system) to measure fat thickness, LM area (LMA), and intramuscular fat (IMF). Two steaks were removed from the 12th rib location and aged for 72 h and 14 d to determine Warner-Bratzler shear force and cooking loss. Sire breed x sex interactions were not significant (P > 0.05). Angus-sired calves had greater (P Angus. Sire breed did not affect (P > 0.20) HCW, 12th-rib fat, or USDA yield grade. Carcasses of Wagyu had greater (P = 0.0001) marbling scores at the 12th rib than those of Angus (770.9 vs. 597.3 +/- 41.01, respectively). Carcasses of Wagyu also had greater (P Angus, resulting in a greater proportion of carcasses grading Prime (65.0 vs. 21.1%; P = 0.006). Carcasses from Wagyu tended (P = 0.08) to have greater LMA at the 12th rib, whereas Angus carcasses had greater (P Angus and Wagyu had similar (P > 0.50) tenderness at aging times of 72 h and 14 d. Cooking loss was greater (P Angus than Wagyu steaks at 72 h and 14 d. Using Wagyu sires vs. Angus sires on British-based commercial cows combined with early weaning management strategies has the potential to produce a product with greater marbling, but is unlikely to significantly enhance tenderness.

Tender wheatgrass is being consumed by human beings in juice form or as it is due to its antioxidant potential and medicinal value. Systematic studies were carried out to (i) estimate elemental profiles as a function of growth period and conditions, bioaccessibility of different elements and the antioxidant potential of the tender wheatgrass, (ii) determine the optimum growth period for obtaining maximum benefit and (iii) examine the possible correlation between antioxidant potential and mineral content. Wheatgrass was grown in four different conditions namely (i) tap water, (ii) tap water with nutrients, (iii) soil and tap water and (iv) soil with nutrient solution. The studies were carried out on the wheatgrass of 5-20 days old. For comparison with laboratory grown wheatgrass, a set of commercially available wheatgrass tablets and wheat seeds were also studied. Instrumental neutron activation analysis (INAA) was used for concentration determination of elements in the wheatgrass, wheat seeds and wheatgrass tablets. A total of 15 elements like Na, K, Ca, Mg, Mn, Br, Fe and Zn were determined in the samples of shoots and roots of tender wheatgrass. A comparison with the recommended dietary allowance (RDA) of different essential elements with that in tender wheatgrass revealed that wheatgrass is a good source of minerals for health benefits rather than a food supplement. Bioaccessible fractions of various elements were estimated by a chemical NAA method by subjecting the samples to in vitro gastric and gastro-intestinal digestion followed by NAA. The bioaccessibility concentrations by both the measurements were in the range of 9-60%. It was found that bioaccessibility of the elements studied was the highest from fresh wheatgrass and the lowest from wheat seeds. Accuracy of the NAA method was evaluated by analyzing two biological reference materials, SRM 1573a (Tomato leaves) from NIST, USA and ICHTJ CTA-vtl-2 (Tobacco leaves) from INCT, Poland.

This study tries to understand the relation between the reality of the nurse's everyday work and the construction process of this identity, using Agnes Heller's sociological theory of everyday life as the main reference. The possibilities of the worker's expression and fulfillment occur through objective and subjective elements of job reality which comes upon the worker as people who put order and tension in their everyday job; these job determinants imprint and produce impacts, giving sense to the work quality and constructing concrete possibilities to the worker to manifest him/herself as Whole being, guiding the construction of his/her identity.

Regulatory polymorphisms in the bovine Ankyrin 1 gene promoter are associated with tenderness and intra-muscular fat content

LENUS (Irish Health Repository)

Aslan, Ozlem

2010-12-15

Abstract Background Recent QTL and gene expression studies have highlighted ankyrins as positional and functional candidate genes for meat quality. Our objective was to characterise the promoter region of the bovine ankyrin 1 gene and to test polymorphisms for association with sensory and technological meat quality measures. Results Seven novel promoter SNPs were identified in a 1.11 kb region of the ankyrin 1 promoter in Angus, Charolais and Limousin bulls (n = 15 per breed) as well as 141 crossbred beef animals for which meat quality data was available. Eighteen haplotypes were inferred with significant breed variation in haplotype frequencies. The five most frequent SNPs and the four most frequent haplotypes were subsequently tested for association with sensory and technological measures of meat quality in the crossbred population. SNP1, SNP3 and SNP4 (which were subsequently designated regulatory SNPs) and SNP5 were associated with traits that contribute to sensorial and technological measurements of tenderness and texture; Haplotype 1 and haplotype 4 were oppositely correlated with traits contributing to tenderness (P < 0.05). While no single SNP was associated with intramuscular fat (IMF), a clear association with increased IMF and juiciness was observed for haplotype 2. Conclusion The conclusion from this study is that alleles defining haplotypes 2 and 4 could usefully contribute to marker SNP panels used to select individuals with improved IMF\\/juiciness or tenderness in a genome-assisted selection framework.

Studies have been carried out at the Japan Atomic Energy Research Institute (JAERI) on hydrogen production through thermochemical processes such as water-splitting. These studies are classified with iodine-sulphur cycle studies using heat from high temperature gas-cooled reactors. An experimental apparatus was constructed with fluorine resin, glass and quartz. It can produce hydrogen at a rate of 50 litres per hour. Electricity provides the heat required for the operation. The closed chemical process requires special control techniques. The process flow diagram for the apparatus was designed based on the results of previous studies including one where hydrogen production was successfully achieved at a rate of one liter per hour for 48 hours. Experimental operations under atmospheric pressure will be carried out for the next four years to develop the process. The data will be used in the next research and development programs aimed at designing a bench-scale apparatus. 7 refs., 1 tab., 8 figs.

Full Text Available The industrialised building system (IBS survey has become an essential tool for ensuring the IBS Roadmap (2003 to 2010 meets its goals and target. As part of the process review survey, it also records the trend achievement of Malaysia in the usage of IBS in the building construction industry. The first and second IBS surveys were published in 2003 and 2005, respectively. Afterward, the IBS Roadmap’s midterm review was conducted. The third and the most recent IBS surveys were conducted in 2008 and 2010, respectively. This paper aims to highlight a part of the IBS survey report in 2010, which has been conducted to measure the drivers, barriers and the critical success factors of G7 contractors in adopting IBS construction. G7 is a Construction Industry Development Board contractor grade that can apply tender without limit. The importance of this paper is that it guides the policy and implementation strategy of IBS by G7 contractors. The survey shows that the acceptance, adoption, and deployment of IBS in the Malaysian construction industry are still low and do not address the persisting problems, such as productivity, dependency on foreign workers and high level of construction wastage.

This study investigated the effect of reactive oxygen species-mediated oxidative stress on activation of mitochondrial apoptosis and tenderness of yak meat during postmortem ageing. Oxidative stress degree, Ca 2+ levels, membrane permeability transition pore opening, mitochondrial membrane potential, apoptotic factors and the shear force were examined. Results showed that the ROS generated by H 2 O 2 significantly increased mitochondrial oxidative stress by decreasing the activities of superoxide dismutase, catalase and glutathione peroxidase, and increasing lipid peroxidation. Furthermore, oxidative stress enhanced Ca 2+ production and cytochrome c release, changed the levels of Bcl-2 family proteins and activated caspase-9 and -3 activities. Ultimately, oxidative stress increased the apoptosis rate and tenderness of yak meat. These observations confirmed that ROS-mediated oxidative stress participates in the activation of the apoptotic cascade reaction involving Ca 2+ and Bcl-2 family proteins. The results further suggested that ROS-mediated oxidative stress plays a significant role in meat tenderization through the mitochondrial apoptotic pathway. Copyright © 2017.

A BPMN-Based Process Map for the Design and Construction of Façades

Directory of Open Access Journals (Sweden)

Eleanor Voss

2013-12-01

Full Text Available Process mapping can lead to significant efficiency and quality improvements in construction engineering and is an ideal basis for developing IT support tools. The increasing complexity and multidisciplinary nature of façade design and construction suggest that a process map would be beneficial in this sector of the construction industry, but it has received limited attention to date. This paper presents a verified process map of the façade design and construction process.  The map is the first of its kind to represent, in detail, the whole process relevant to all façade types, from commencement of the façade consultant’s and contactor’s participation, to the end of their involvement. The paper describes the process by which the mapping notation was selected, followed by the development and verification of the process map, including testing in two independent research projects. The BuildingSMART’s BPMN notation is found to have superior system features and comprehensibility for this application and the resulting process map is easy to interpret and verify by industry experts. The trialling of the map in the two research projects indicate that the map is a useful tool for assessing process improvements in the façades sector.

LHC Civil Engineering Construction Contracts Cost Monitoring and Budget Forecasting

CERN Document Server

Skelton, K

2000-01-01

The Civil Engineering project for the LHC is estimated at 350 MCHF, of which about 316 MCHF is for the construction contracts. These contracts are based on a system of remeasurement whereby the consultant estimates the quantities required for the construction of each structure and the contractor commits himself to the unit price, which define the initial tender price. There are many factors that affect the final price for these contracts, from increases or decreases in quantities of the estimated amounts in the original bill of quantities to variations to the contract. This paper will look at how these factors change costs at the individual level of a structure to the overall costs of the contract. It will look at how the Civil Engineering Group monitors these changes to calculate cash flows and final costs and how this information is used as a basis for budget forecasts.

Ibrahim Motawa

2012-11-01

Full Text Available Modelling change processes within construction projects isessential to implement changes efficiently. Incomplete informationon the project variables at the early stages of projects leads toinadequate knowledge of future states and imprecision arisingfrom ambiguity in project parameters. This lack of knowledge isconsidered among the main source of changes in construction.Change identification and evaluation, in addition to predictingits impacts on project parameters, can help in minimising thedisruptive effects of changes. This paper presents a systematicapproach to modelling change process within construction projectsthat helps improve change identification and evaluation. Theapproach represents the key decisions required to implementchanges. The requirements of an effective change processare presented first. The variables defined for efficient changeassessment and diagnosis are then presented. Assessmentof construction changes requires an analysis for the projectcharacteristics that lead to change and also analysis of therelationship between the change causes and effects. The paperconcludes that, at the early stages of a project, projects with a highlikelihood of change occurrence should have a control mechanismover the project characteristics that have high influence on theproject. It also concludes, for the relationship between changecauses and effects, the multiple causes of change should bemodelled in a way to enable evaluating the change effects moreaccurately. The proposed approach is the framework for tacklingsuch conclusions and can be used for evaluating change casesdepending on the available information at the early stages ofconstruction projects.

Plants in constructed wetlands help to treat agricultural processing wastewater

Mark Grismer

2008-05-01

Full Text Available Over the past three decades, wineries in the western United States and sugarcane processing for ethanol in Central and South America have experienced problems related to the treatment and disposal of process wastewater. Both winery and sugarcane (molasses wastewaters are characterized by large organic loadings that change seasonally and are detrimental to aquatic life. We examined the role of plants for treating these wastewaters in constructed wetlands. In the greenhouse, subsurface-flow flumes with volcanic rock substrates and plants steadily removed approximately 80% of organic-loading oxygen demand from sugarcane process wastewater after about 3 weeks of plant growth; unplanted flumes removed about 30% less. In field studies at two operational wineries, we evaluated the performance of similar-sized, paired, subsurface constructed wetlands with and without plants; while both removed most of the oxygen demand, removal rates in the planted system were slightly greater and significantly different from those of the unplanted system under field conditions.

Building the Monumental Source Alameda Afonso Henriques (1938-1948 through journals and administrative process

2010-02-01

The research was based primarily on data collected in the process of work, existing file. The journals have been the prime source to describe the construction of the Monumental Fountain. However, given the political context of the time, the journals say little about the logic that led to the belated realization of the work, since their concern is, above all, credibility and consolidate the political image of the regime. In this study, the consultation of journals made by the need to contextualize the motivations of political and ideological order that accompanied the launching of the construction. In the absence of justification on the grounds that caused the delay in the work, we used to see the file's administrative order. This made it possible to obtain unpublished data on the construction of commemorative works such as launching an international tender for electrical installation and plumbing of water games or contingencies that led to the tardy commencement of the works and the replacement of material originally intended for artistic commissions.

Full Text Available The purpose of this article is to identify the factors influencing the probability of winning in public procurement procedures and to assess the strength of their impact from the perspective of both: the bidder and procurer. The research was conducted with the use of series of quantitative methods: binary logistic regression, discriminant analysis and cluster analysis. It was based on a sample consisting of public tenders, in which the examined company performed the role of a bidder. Thus, the research process was aimed at both identifying the factors of success and estimating the probability of achieving it, where it was possible to obtain probabilities. The main idea of this research is to answer questions about the utility of various methods of quantitative analysis in the case of analyzing determinants of success. Results of the research are presented in the following sequence of sections: characteristics of the examined material, the process of modelling the probability of winning, evaluation of the quality of the results obtained.

Garrard, R.S.; Salmons, B.H.

1976-01-01

The paper deals with experience gained at Hartlepool and Heysham. These Power Station Projects have now passed through the 'enquiry', 'tender' and 'placing-of-order' stages, and are deeply involved at present in the detailed 'design', 'construction' and 'setting-to-work' phases. Quality Assurance in the widest concept has been active throughout, but experience has shown that Quality Assurance Programmes should have played a more positive role, particularly in the early stages. Difficulties have arisen because the prototype nature of the plant was not fully appreciated at the time of Enquiry and Tender. On occasion, manufacture has had to proceed, before detailed design proving was achieved, in order to maintain the Construction Programme. However, in one or two instances, this approach was shown to be false economy as more time was used in rework after all the technical parameters had been established. It is now recognised that a fully integrated Quality Assurance function is one of the essential tools for establishing a viable Programme for the Project, and maintaining Product Quality consistent with Plant Reliability. A description is given in this Paper of the methods which have been developed for the approval of Designs and Manufacturing Procedures, together with Techniques in use to ensure that Quality Requirements are known, understood and implemented.

Process-Based Modeling of Constructed Wetlands

Science.gov (United States)

Baechler, S.; Brovelli, A.; Rossi, L.; Barry, D. A.

2007-12-01

Constructed wetlands (CWs) are widespread facilities for wastewater treatment. In subsurface flow wetlands, contaminated wastewater flows through a porous matrix, where oxidation and detoxification phenomena occur. Despite the large number of working CWs, system design and optimization are still mainly based upon empirical equations or simplified first-order kinetics. This results from an incomplete understanding of the system functioning, and may in turn hinder the performance and effectiveness of the treatment process. As a result, CWs are often considered not suitable to meet high water quality-standards, or to treat water contaminated with recalcitrant anthropogenic contaminants. To date, only a limited number of detailed numerical models have been developed and successfully applied to simulate constructed wetland behavior. Among these, one of the most complete and powerful is CW2D, which is based on Hydrus2D. The aim of this work is to develop a comprehensive simulator tailored to model the functioning of horizontal flow constructed wetlands and in turn provide a reliable design and optimization tool. The model is based upon PHWAT, a general reactive transport code for saturated flow. PHWAT couples MODFLOW, MT3DMS and PHREEQC-2 using an operator-splitting approach. The use of PHREEQC to simulate reactions allows great flexibility in simulating biogeochemical processes. The biogeochemical reaction network is similar to that of CW2D, and is based on the Activated Sludge Model (ASM). Kinetic oxidation of carbon sources and nutrient transformations (nitrogen and phosphorous primarily) are modeled via Monod-type kinetic equations. Oxygen dissolution is accounted for via a first-order mass-transfer equation. While the ASM model only includes a limited number of kinetic equations, the new simulator permits incorporation of an unlimited number of both kinetic and equilibrium reactions. Changes in pH, redox potential and surface reactions can be easily incorporated

The author comments the answers to a call for tender made by the French government and concerning five offshore wind farm sites (Le Treport, Fecamp, Courseulles sur Mer, Saint-Brieuc and Saint-Nazaire). As they are present within the three consortiums, Areva and Alstom should provide the wind turbines. This would result in the construction by Alstom of two blade and mast factories and two turbine and pad factories. For both companies, this market of 500 to 600 turbines is an opportunity. Many jobs are at stake. They push themselves forward for their experience or their innovation capacity. But their wind turbines will be based on foreign (Spanish or German) technology

1999-01-01

This document concerns the supply of thyratrons to be used as high-voltage and high-current switches for the fast-pulsed magnet systems of the CERN accelerators and for the protection of the klystrons of RF systems. In June 1981 the Finance Committee approved the placing, without competitive tendering, of a blanket order with EEV Ltd (UK) for a total value of up to 2 000 000 Swiss francs to cover the supply of thyratrons for the years 1982, 1983 and 1984. New blanket orders were subsequently negotiated for three-year periods with the approval of the Finance Committee in 1984, 1987, 1990 and 1993. After a new market survey in 1995-1996 had confirmed that EEV Ltd is the sole manufacturer of such thyratrons in the CERN Member States, a new blanket order was negotiated in 1996 with the approval of the Finance Committee. The Finance Committee is invited to agree to the negotiation, without competitive tendering, of a new blanket order with EEV Ltd (UK) for up to 800 000 pounds sterling to cover the supply of thyra...

The manufacture of construction materials from locally available resources in space is an important first step in the establishment of lunar and planetary bases. The objective of the CoMPULSIVE (Construction Material Processed Using Lunar Simulant In Various Environments) experiment is to develop a procedure to produce construction materials by sintering or melting Johnson Space Center Simulant 1 (JSC-1) lunar soil simulant in both earth-based (1-g) and microgravity (approximately 0-g) environments. The characteristics of the resultant materials will be tested to determine its physical and mechanical properties. The physical characteristics include: crystalline, thermal, and electrical properties. The mechanical properties include: compressive tensile, and flexural strengths. The simulant, placed in a sealed graphite crucible, will be heated using a high temperature furnace. The crucible will then be cooled by radiative and forced convective means. The core furnace element consists of space qualified quartz-halogen incandescent lamps with focusing mirrors. Sample temperatures of up to 2200 C are attainable using this heating method.

A BPMN-based process map for the design and construction of façades

2013-12-01

Full Text Available Corresponding author: Eleanor Voss, Glass and Façade Technology Research Group, Department of Engineering, University of Cambridge, Trumpington Street, Cambridge, UK. E-mail: ev236@cam.ac.uk Process mapping can lead to significant efficiency and quality improvements in construction engineering and is an ideal basis for developing IT support tools. The increasing complexity and multidisciplinary nature of façade design and construction suggest that a process map would be beneficial in this sector of the construction industry, but it has received limited attention to date. This paper presents a verified process map of the façade design and construction process. The map is the first of its kind to represent, in detail, the whole process relevant to all façade types, from commencement of the façade consultant's and contactor's participation, to the end of their involvement. The paper describes the process by which the mapping notation was selected, followed by the development and verification of the process map, including testing in two independent research projects. The BuildingSMART's BPMN notation is found to have superior system features and comprehensibility for this application and the resulting process map is easy to interpret and verify by industry experts. The trialling of the map in the two research projects indicate that the map is a useful tool for assessing process improvements in the façades sector.

Constructing large scale SCI-based processing systems by switch elements

1993-05-01

The goal of this paper is to study some of the design criteria for the switch elements to form the interconnection of large scale SCI-based processing systems. The approved IEEE standard 1596 makes it possible to couple up to 64K nodes together. In order to connect thousands of nodes to construct large scale SCI-based processing systems, one has to interconnect these nodes by switch elements to form different topologies. A summary of the requirements and key points of interconnection networks and switches is presented. Two models of the SCI switch elements are proposed. The authors investigate several examples of systems constructed for 4-switches with simulations and the results are analyzed. Some issues and enhancements are discussed to provide the ideas behind the switch design that can improve performance and reduce latency. 29 refs., 11 figs., 3 tabs

Logic of historical development of the formation process of architectural and construction solutions

Full Text Available In research field of development processes of architectural and construction decisions (ACD there is already very considerable scientific, normative and technical material. And still in the end of the research boom in this area (the 90th many authors stated their weak return in practical design. High methodological potential gives understanding of the act of ACD formation as a special kind of activity, and its structure - as historical phenomenon that allows to put two main methodological principles in the basis of the research: the principle of activity and the principle of level organization of historically formed objects. As a result it was succeeded to reveal 6 main stages of historical development of ACD formation process and 6 levels of its modern organization. Origin stage - is the transition from animal to human construction and emergence of the first stage of ACD formation - a measurement. The reproductive stage is characterized by centuries-old reproduction of steady volume forms of constructions. At a composite stage professional presentation detaches external form of a construction from architectural and construction actions and techniques. There occurs transformation into a subject of architectural and construction activity and creation of a method of composition on this basis. At a constructive stage engineers are involved in construction process, there is a change of style of thinking, emergence of construction designs and emergence of a new function of ACD means of configuration, and, at last, final allocation and separation of architectural and construction design from construction. Technological stage is a product of industrialization of construction on which systematization is carried out not only on the level of subject, but also in respect to the operational contents that leads to emergence of ACD program formation. At the sixth, methodological stage of development of ASP, a leading way change of the ACD formation becomes a

The influence of government targeted procurement strategies on the growth performance of construction small and medium-sized contractors (SMCs in South Africa

Full Text Available This paper examines government targeted procurement (TP strategies in South Africa and whether these strategies have an influence on the growth performance of Small and medium-sized contractors (SMCs in the construction industry. The rationale for this study stems from reports that while TP has been widely used as an instrument to improve the position of SMCs in the South African construction industry, three out of five SMCs do not become established firms. In addition, the nature of the influence of TP strategies on the growth performance of SMCs is not known. Following a review of existing literature, the study mainly adopted a quantitative research approach. Questionnaire surveys were administered to Construction Industry Development Board (cidb Grades 3 to 6 contractors that have executed TP projects within the last 5 years. The collected data was subjected to descriptive and inferential statistical analyses – Spearman’s rank order correlation was used as an index of association between the study variables. The study found that tendering equity is the most frequently used TP strategy, closely followed by preferencing and mandatory subcontracting. The study also found that positive significant associations exists among preferencing and turnover; third-party management and company assets; tendering equity, turnover and number of employees; as well as accelerated rotations, turnover and number of employees. The study concluded that government intervention through targeted procurement has the potential to achieve its intended results of improving the position of historically disadvantaged SMCs in the construction industry in South Africa if selected and implemented appropriately.

2016-07-01

Full Text Available The present theoretical paper analyzes the way mediatic communication construct identifications. The thesis proposed is that the media configure ritually and dramatically identifications made by individuals and groups. First of all, we show the limitations of the concept of “identity” and we propose to use “identification” instead. Second, we explore the extent of social drama theory and role theory and we open it to new theoretical challenges and perspectives. Thirdly, it is shown that the concept of "ritual" is very useful to understand and interpret the identity construction through the media. All this leads us to conclude that both the theatricality and rituality are key to understanding the processes of identification that individuals and groups make in relation to the media.

Systematic construction of qualitative physics-based rules for process diagnostics

Reifman, J.; Wei, T.Y.C.

1995-01-01

A novel first-principles-based expert system is proposed for on-line detection and identification of faulty component candidates during incipient off-normal process operations. The system performs function-oriented diagnostics and can be reused for diagnosing single-component failures in different processes and different plants through the provision of the appropriate process schematics information. The function-oriented and process-independent diagnostic features of the proposed expert system are achieved by constructing a knowledge base containing three distinct types of information, qualitative balance equation rules, functional classification of process components, and the process piping and instrumentation diagram. The various types of qualitative balance equation rules for processes utilizing single-phase liquids are derived and their usage is illustrated through simulation results of a realistic process in a nuclear power plant

Full Text Available The article outlines the legislation concerning the methodology of estimating the value of works in Poland and the Czech Republic. In both countries it is necessary for the public investor to respect the law governing public procurement, which defines the structure of compulsory documents needed for the tender documentation, but not directly the way of their preparation. In both countries, though, there exist model proceeding schedules for the calculation of the value of a public procurement for construction works. To illustrate and compare the calculation methods a sample calculation of the procurement value is presented for a selected thermal efficiency improvement project.

Xie, Yu; Jiang, Shengshi; Zheng, Jie; Lan, Zhenggang

2017-12-21

Photoinduced excited-state electron and energy transfer processes are crucial in biological photoharvesting systems and organic photovoltaic devices. We discuss the construction of a diabatic vibronic Hamiltonian for the proper treatment of these processes involving the projection approach acting on both electronic wave functions and vibrational modes. In the electronic part, the wave function projection approach is used to construct the diabatic Hamiltonian in which both local excited states and charge-transfer states are included on the same footing. For the vibrational degrees of freedom, the vibronic couplings in the diabatic Hamiltonian are obtained in the basis of the pseudonormal modes localized on each monomer site by applying delocalized-to-localized mode projection. This systematic approach allows us to construct the vibronic diabatic Hamiltonian in molecular aggregates.

Numerical construction of the p(fold) (committor) reaction coordinate for a Markov process.

Science.gov (United States)

Krivov, Sergei V

2011-10-06

To simplify the description of a complex multidimensional dynamical process, one often projects it onto a single reaction coordinate. In protein folding studies, the folding probability p(fold) is an optimal reaction coordinate which preserves many important properties of the dynamics. The construction of the coordinate is difficult. Here, an efficient numerical approach to construct the p(fold) reaction coordinate for a Markov process (satisfying the detailed balance) is described. The coordinate is obtained by optimizing parameters of a chosen functional form to make a generalized cut-based free energy profile the highest. The approach is illustrated by constructing the p(fold) reaction coordinate for the equilibrium folding simulation of FIP35 protein reported by Shaw et al. (Science 2010, 330, 341-346). © 2011 American Chemical Society

Research reported here also considers the analysis of the Russian and international legislation of the quality control of processes in green construction.

Desirable and undesirable future thoughts call for different scene construction processes.

de Vito, S; Neroni, M A; Gamboz, N; Della Sala, S; Brandimonte, M A

2015-01-01

Despite the growing interest in the ability of foreseeing (episodic future thinking), it is still unclear how healthy people construct possible future scenarios. We suggest that different future thoughts require different processes of scene construction. Thirty-five participants were asked to imagine desirable and less desirable future events. Imagining desirable events increased the ease of scene construction, the frequency of life scripts, the number of internal details, and the clarity of sensorial and spatial temporal information. The initial description of general personal knowledge lasted longer in undesirable than in desirable anticipations. Finally, participants were more prone to explicitly indicate autobiographical memory as the main source of their simulations of undesirable episodes, whereas they equally related the simulations of desirable events to autobiographical events or semantic knowledge. These findings show that desirable and undesirable scenarios call for different mechanisms of scene construction. The present study emphasizes that future thinking cannot be considered as a monolithic entity.

The necessity to identify common parameters that characterize the interaction nature of all the technology-related construction and installation processes and activities is shown. The research of the technologies of construction and installation processes for buildings and structures with the goal of determining a common parameter for evaluating the relationship between technologically interconnected processes and construction works are conducted. The result of this research was to identify the quantitative evaluation of interaction construction and installation processes and activities in a minimum technologically necessary volume of the previous process allowing one to plan and organize the execution of a subsequent technologically interconnected process. The quantitative evaluation is used as the basis for the calculation of the optimum range of the combination of processes and activities. The calculation method is based on the use of the graph theory. The authors applied a generic characterization parameter to reveal the technological links between construction and installation processes, and the proposed technique has adaptive properties which are key for wide use in organizational decisions forming. The article provides a written practical significance of the developed technique.

Elementary Introduction to the Green Management of the Construction in Whole Process

Science.gov (United States)

Na), Wu Y. N.(Yun; Yu), Yan H. Y.(Hong; Jun), Huang Z. J.(Zhi

Construction industries consume more energy resources than necessary. it is essential to establish a management system with all pollution problems resolved to construct green buildings. By applying the theory of whole life cycle, this paper divides the whole process of construction into four sub-phases, which will also be subdivided into more concrete working procedures. Based on this, a systematic framework is promoted for the green management of the construction, especially and creatively, considering the green aims as important as the traditional three aims-"quality aim, schedule aim and cost aim". This framework, adhering to the integration idea-"customers first, whole optimal", regards the green control and workflow as an organic whole in order to build green, sustainable and healthy architecture, and then provide a perfect guide and reference to the green management.

Involving construction in the preliminary engineering process

International Nuclear Information System (INIS)

Mahoney, D.T. Jr.; Boccieri, S.V. Jr.

1994-01-01

With today's high cost associated with modifications in nuclear power plants, it is imperative that the authors continue to investigate ways to cut costs but at the same time improve efficiency and reduce radiation exposure to those directly associated with the implementation of modifications. The success associated with involving construction in the preliminary engineering process will not only cut costs and improve efficiency but will establish a Team Building concept to provide accountability to all those associated with the implementation of the task. This form of partnering focuses on the solutions rather than highlighting the difficulties. This paper will demonstrate techniques to implement such ideas and provide examples to corroborate actual successes already achieved

Occipital neuralgia (ON) is characterized by lancinating pain and tenderness overlying the occipital nerves. Both steroid injections and pulsed radiofrequency (PRF) are used to treat ON, but few clinical trials have evaluated efficacy, and no study has compared treatments. We performed a multicenter, randomized, double-blind, comparative-effectiveness study in 81 participants with ON or migraine with occipital nerve tenderness whose aim was to determine which treatment is superior. Forty-two participants were randomized to receive local anesthetic and saline, and three 120 second cycles of PRF per targeted nerve, and 39 were randomized to receive local anesthetic mixed with deposteroid and 3 rounds of sham PRF. Patients, treating physicians, and evaluators were blinded to interventions. The PRF group experienced a greater reduction in the primary outcome measure, average occipital pain at 6 weeks (mean change from baseline -2.743 ± 2.487 vs -1.377 ± 1.970; P occipital pain through 3 months (mean change from baseline -1.925 ± 3.204 vs -0.541 ± 2.644; P = 0.043), and average overall headache pain through 6 weeks (mean change from baseline -2.738 ± 2.753 vs -1.120 ± 2.1; P = 0.037). Adverse events were similar between groups, and few significant differences were noted for nonpain outcomes. We conclude that although PRF can provide greater pain relief for ON and migraine with occipital nerve tenderness than steroid injections, the superior analgesia may not be accompanied by comparable improvement on other outcome measures.

2018-03-01

An outbreak of enterohaemorrhagic Escherichia coli O157 occurred in multiple prefectures of Japan in November 2009. We conducted two case-control studies with trace-back and trace-forward investigations to determine the source. The case definition was met by 21 individuals; 14 (66.7%) were hospitalised, but no haemolytic uraemic syndrome, acute encephalopathy or deaths occurred. Median age was 23 (range 12-48) years and 14 cases were male (66.7%). No significant associations with food were found in a case-control study by local public health centres, but our matched case-control study using Internet surveys found that beef hanging tender (or hanger steak), derived from the diaphragm of the cattle, was significantly associated with illness (odds ratio = 15.77; 95% confidence interval, 2.00-124.11). Pulsed-field gel electrophoresis analysis of isolates from patients and the suspected food showed five different patterns: two in faecal and food samples, and another three in patient faecal samples only, although there were epidemiological links to the meat consumed at the restaurants. Trace-back investigation implicated a common food processing company from outside Japan. Examination of the logistics of the meat processing company suggested that contamination did not occur in Japan. We concluded that the source of the outbreak was imported hanging tender. This investigation revealed that Internet surveys could be useful for outbreak investigations.

Lévy matters VI Lévy-type processes moments, construction and heat kernel estimates

CERN Document Server

Kühn, Franziska

2017-01-01

Presenting some recent results on the construction and the moments of Lévy-type processes, the focus of this volume is on a new existence theorem, which is proved using a parametrix construction. Applications range from heat kernel estimates for a class of Lévy-type processes to existence and uniqueness theorems for Lévy-driven stochastic differential equations with Hölder continuous coefficients. Moreover, necessary and sufficient conditions for the existence of moments of Lévy-type processes are studied and some estimates on moments are derived. Lévy-type processes behave locally like Lévy processes but, in contrast to Lévy processes, they are not homogeneous in space. Typical examples are processes with varying index of stability and solutions of Lévy-driven stochastic differential equations. This is the sixth volume in a subseries of the Lecture Notes in Mathematics called Lévy Matters. Each volume describes a number of important topics in the theory or applicati ons of Lévy processes and pays ...

We evaluated the effect of commercial times and temperatures for searing, cooking, and holding on the destruction of Escherichia coli O157:H7 (ECOH) within mechanically tenderized prime rib. Boneless beef ribeye was inoculated on the fat side with ca. 5.7 log CFU/g of a five-strain cocktail of ECOH and then passed once through a mechanical tenderizer with the fat side facing upward. The inoculated and tenderized prime rib was seared by broiling at 260°C for 15 min in a conventional oven and then cooked in a commercial convection oven at 121.1°C to internal temperatures of 37.8, 48.9, 60.0, and 71.1°C before being placed in a commercial holding oven maintained at 60.0°C for up to 8 h. After searing, ECOH levels decreased by ca. 1.0 log CFU/g. Following cooking to internal temperatures of 37.8 to 71.1°C, pathogen levels decreased by an additional ca. 2.7 to 4.0 log CFU/g. After cooking to 37.8, 48.9, or 60.0°C and then warm holding at 60.0°C for 2 h, pathogen levels increased by ca. 0.2 to 0.7 log CFU/g. However, for prime rib cooked to 37.8°C, pathogen levels remained relatively unchanged over the next 6 h of warm holding, whereas for those cooked to 48.9 or 60.0°C pathogen levels decreased by ca. 0.3 to 0.7 log CFU/g over the next 6 h of warm holding. In contrast, after cooking prime rib to 71.1°C and holding for up to 8 h at 60.0°C, ECOH levels decreased by an additional ca. 0.5 log CFU/g. Our results demonstrated that to achieve a 5.0-log reduction of ECOH in blade tenderized prime rib, it would be necessary to sear at 260°C for 15 min, cook prime rib to internal temperatures of 48.9, 60.0, or 71.1°C, and then hold at 60.0°C for at least 8 h.

This is the second in a series of two papers regarding the construction of data quality (DQ) assured repositories, based on population data from Electronic Health Records (EHR), for the reuse of information on infant feeding from birth until the age of two. This second paper describes the application of the computational process of constructing the first quality-assured repository for the reuse of information on infant feeding in the perinatal period, with the aim of studying relevant questions from the Baby Friendly Hospital Initiative (BFHI) and monitoring its deployment in our hospital. The construction of the repository was carried out using 13 semi-automated procedures to assess, recover or discard clinical data. The initial information consisted of perinatal forms from EHR related to 2048 births (Facts of Study, FoS) between 2009 and 2011, with a total of 433,308 observations of 223 variables. DQ was measured before and after the procedures using metrics related to eight quality dimensions: predictive value, correctness, duplication, consistency, completeness, contextualization, temporal-stability, and spatial-stability. Once the predictive variables were selected and DQ was assured, the final repository consisted of 1925 births, 107,529 observations and 73 quality-assured variables. The amount of discarded observations mainly corresponds to observations of non-predictive variables (52.90%) and the impact of the de-duplication process (20.58%) with respect to the total input data. Seven out of thirteen procedures achieved 100% of valid births, observations and variables. Moreover, 89% of births and ~98% of observations were consistent according to the experts׳ criteria. A multidisciplinary approach along with the quantification of DQ has allowed us to construct the first repository about infant feeding in the perinatal period based on EHR population data.

Charinee Limsawasd

2017-03-01

Full Text Available Climate change and greenhouse gas (GHG emissions have attracted much attention for their impacts upon the global environment. Initiating of new legislation and regulations for control of GHG emissions from the industrial sectors has been applied to address this problem. The transportation industries, which include operation of road pavement and pavement construction equipment, are the highest GHG-emitting sectors. This study presents a novel quantification model of GHG emissions of pavement construction using process-based analysis. The model is composed of five modules that evaluate GHG emissions. These are: material production and acquisition, (2 material transport to a project site, (3 heavy equipment use, (4 on-site machinery use, and, (5 on-site electricity use. The model was applied to a hypothetical pavement project to compare the environmental impacts of flexible and rigid pavement types during construction. The resulting model can be used for evaluation of environmental impacts, as well as for designing and planning highway pavement construction.

An Algorithm for Modelling the Impact of the Judicial Conflict-Resolution Process on Construction Investment

Directory of Open Access Journals (Sweden)

Andrej Bugajev

2018-01-01

Full Text Available In this article, the modelling of the judicial conflict-resolution process is considered from a construction investor’s point of view. Such modelling is important for improving the risk management for construction investors and supporting sustainable city development by supporting the development of rules regulating the construction process. Thus, this raises the problem of evaluation of different decisions and selection of the optimal one followed by distribution extraction. First, the example of such a process is analysed and schematically represented. Then, it is formalised as a graph, which is described in the form of a decision graph with cycles. We use some natural problem properties and provide the algorithm to convert this graph into a tree. Then, we propose the algorithm to evaluate profits for different scenarios with estimation of time, which is done by integration of an average daily costs function. Afterwards, the optimisation problem is solved and the optimal investor strategy is obtained—this allows one to extract the construction project profit distribution, which can be used for further analysis by standard risk (and other important information-evaluation techniques. The overall algorithm complexity is analysed, the computational experiment is performed and conclusions are formulated.

2015-01-01

Social media are increasingly being used for educational purposes. The first part of this article briefly reviews literature that reports on educational applications of social media tools. The second part discusses theories that may provide a basis for analyzing the processes that are relevant for individual learning and collective knowledge construction. We argue that a systems-theoretical constructivist approach is appropriate to examine the processes of educational social media use, namely, self-organization, the internalization of information, the externalization of knowledge, and the interplay of externalization and internalization providing the basis of a co-evolution of cognitive and social systems. In the third part we present research findings that illustrate and support this systems-theoretical framework. Concluding, we discuss the implications for educational design and for future research on learning and collective knowledge construction with social media. PMID:26246643

Although there is substantial evidence to support the efficacy of cognitive-behavioral treatments (CBT) for posttraumatic stress disorder (PTSD), there is some debate about how these treatments have their effects. Modern learning theory and cognitive and emotional processing theories highlight the importance of reducing avoidance, facilitating the constructive processing of feared experiences, and strengthening new inhibitory learning. We examined variables thought to be associated with unproductive and constructive processing of traumatic experiences in a sample of 81 youth with elevated PTSD symptoms, who received Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for abuse or traumatic interpersonal loss. Sessions during the trauma narrative phase of TF-CBT were coded for indicators of unproductive processing (overgeneralization, rumination, avoidance) and constructive processing (decentering, accommodation of corrective information), as well as levels of negative emotion. In previous analyses of this trial (Ready et al., 2015), more overgeneralization during the narrative phase predicted less improvement in internalizing symptoms at posttreatment and a worsening of externalizing symptoms over the 12-month follow-up. In contrast, more accommodation predicted improvement in internalizing symptoms and also moderated the negative effects of overgeneralization on internalizing and externalizing symptoms. The current study examined correlates of overgeneralization and accommodation. Overgeneralization was associated with more rumination, less decentering, and more negative emotion, suggesting immersion in trauma-related material. Accommodation was associated with less avoidance and more decentering, suggesting a healthy distance from trauma-related material that might allow for processing and cognitive change. Decentering also predicted improvement in externalizing symptoms at posttreatment. Rumination and avoidance showed important associations with

An Integrated Framework for Process-Driven Model Construction in Disease Ecology and Animal Health

Directory of Open Access Journals (Sweden)

Rebecca Mancy

2017-09-01

Full Text Available Process models that focus on explicitly representing biological mechanisms are increasingly important in disease ecology and animal health research. However, the large number of process modelling approaches makes it difficult to decide which is most appropriate for a given disease system and research question. Here, we discuss different motivations for using process models and present an integrated conceptual analysis that can be used to guide the construction of infectious disease process models and comparisons between them. Our presentation complements existing work by clarifying the major differences between modelling approaches and their relationship with the biological characteristics of the epidemiological system. We first discuss distinct motivations for using process models in epidemiological research, identifying the key steps in model design and use associated with each. We then present a conceptual framework for guiding model construction and comparison, organised according to key aspects of epidemiological systems. Specifically, we discuss the number and type of disease states, whether to focus on individual hosts (e.g., cows or groups of hosts (e.g., herds or farms, how space or host connectivity affect disease transmission, whether demographic and epidemiological processes are periodic or can occur at any time, and the extent to which stochasticity is important. We use foot-and-mouth disease and bovine tuberculosis in cattle to illustrate our discussion and support explanations of cases in which different models are used to address similar problems. The framework should help those constructing models to structure their approach to modelling decisions and facilitate comparisons between models in the literature.

Construction of power plants, foundation work, consisting of a wide variety of construction work, such as plant equipment work. And, civil engineering, technician electrical such as different engineering field, is a comprehensive construction project that works for the design conditions of the structure. However, if the cooperation design conditions is not sufficient, as a construction project, the optimal structures may not be said to have been built. As a result, total cost or increased, including the initial cost of the end construction projects, it is be a cause of the accident. Previous studies, plant equipment construction, is related to safety management and risk of foundation work such as individual construction were many. In this paper, as an example the power plant construction, and performs the following discussion from the point of view of risk management of large-scale construction projects that these individual construction work together with each other. The importance of design conditions cooperation, (1) 'Challenges and countermeasures of ordering method of construction projects', to verify from the (2) 'actually happened substation foundation displacement accident'. And on whether or not the construction project order institutions can be involved in the design from the site preparation stage, we study (3) for 'construction work scope and risk control the construction project ordering institutions to implement' the risk to the natural disaster (earthquake). From these, we describe the challenges and measures in the construction project of the design process. (author)

Decision making in goverment tenders: A formalized qualitative model

Directory of Open Access Journals (Sweden)

Štěpán Veselý

2012-01-01

Full Text Available The paper presents a simple formalized qualitative model of government tenders (GTs. Qualitative models use just three values: Positive/Increasing, Zero/Constant and Negative/Decreasing. Such quantifiers of trends are the least information intensive. Qualitative models can be useful, since GT evaluation often includes such goals as e.g. efficiency of public purchasing, and variables as e.g. availability of relevant information or subjectivity of judgment, that are difficult to quantify. Hence, a significant fraction of available information about GTs is not of numerical nature, e.g. if availability of relevant information is decreasing then efficiency of public purchasing is decreasing as well. Such equationless relations are studied in this paper. A qualitative model of the function F(Goals, Variables is developed. The model has four goal functions, eight variables, and 39 equationless relations. The model is solved and seven solutions, i.e. scenarios are obtained. All qualitative states, including first and second qualitative derivatives with respect to time, of all variables are specified for each scenario. Any unsteady state behavior of the GT model is described by its transitional oriented graph. There are eight possible transitions among seven scenarios. No a priori knowledge of qualitative modeling is required on the reader’s part.

Physical Examination Tools Used to Identify Swollen and Tender Lower Limb Joints in Juvenile Idiopathic Arthritis: A Scoping Review.

Science.gov (United States)

Fellas, Antoni; Singh-Grewal, Davinder; Santos, Derek; Coda, Andrea

2018-01-01

Juvenile idiopathic arthritis (JIA) is the most common form of rheumatic disease in childhood and adolescents, affecting between 16 and 150 per 100,000 young persons below the age of 16. The lower limb is commonly affected in JIA, with joint swelling and tenderness often observed as a result of active synovitis. The objective of this scoping review is to identify the existence of physical examination (PE) tools to identify and record swollen and tender lower limb joints in children with JIA. Two reviewers individually screened the eligibility of titles and abstracts retrieved from the following online databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL. Studies that proposed and validated a comprehensive lower limb PE tool were included in this scoping review. After removal of duplicates, 1232 citations were retrieved, in which twelve were identified as potentially eligible. No studies met the set criteria for inclusion. Further research is needed in developing and validating specific PE tools for clinicians such as podiatrists and other allied health professionals involved in the management of pathological lower limb joints in children diagnosed with JIA. These lower limb PE tools may be useful in conjunction with existing disease activity scores to optimise screening of the lower extremity and monitoring the efficacy of targeted interventions.

After the enactment of the Second Law Amending the Law on Budgetary Principles, the Ordinance on the Confering of Contracts, and the Ordinance on Verification; and the amendment of the ordinances on the placing of construction and delivery orders (VOB and VOL) the European Directives on so-called ''public'' tendering can be said to be transposed into German law as far as they concern construction and delivery orders. This means that as of 1 March 1994 besides the ''classical'' public contractors utilities, too, must invite bids Europe-wide. According to European law this also applies to service orders as of 1 July 1994, but this provision still awaits transposition into German law. (orig.) [de

To explore the relationship between physical factors and tension-type headache in children, the quality of repeated measures was examined. The aim of the present study was to determine the test-retest repeatability of parameters determining isometric neck and shoulder strength and stability, aerobic power, and pericranial tenderness in children. Methods: Twenty-five healthy children, 9 to 18 years of age, participated in test-retest procedures within a 1-week interval. A computerized padded force transducer was used for testing. The tests included the isometric maximal voluntary contraction and force steadiness of neck flexion and extension, and the isometric maximal voluntary contraction and rate of force of the dominant shoulder. Pericranial tenderness was recorded by means of standardized manual palpation, and a submaximal cycle ergometer test predicted maximal oxygen uptake (VO2 max. The measurements were evaluated in steps, using the intraclass correlation coefficient (ICC; changes in the mean between the two test occasions; the levels of agreement, visualized in Bland

Enabling Ethical Code Embeddedness in Construction Organizations: A Review of Process Assessment Approach.

Science.gov (United States)

Oladinrin, Olugbenga Timo; Ho, Christabel Man-Fong

2016-08-01

Several researchers have identified codes of ethics (CoEs) as tools that stimulate positive ethical behavior by shaping the organisational decision-making process, but few have considered the information needed for code implementation. Beyond being a legal and moral responsibility, ethical behavior needs to become an organisational priority, which requires an alignment process that integrates employee behavior with the organisation's ethical standards. This paper discusses processes for the responsible implementation of CoEs based on an extensive review of the literature. The internationally recognized European Foundation for Quality Management Excellence Model (EFQM model) is proposed as a suitable framework for assessing an organisation's ethical performance, including CoE embeddedness. The findings presented herein have both practical and research implications. They will encourage construction practitioners to shift their attention from ethical policies to possible enablers of CoE implementation and serve as a foundation for further research on ethical performance evaluation using the EFQM model. This is the first paper to discuss the model's use in the context of ethics in construction practice.

Full Text Available The construction of the Library of Vila-real, selected in 2012 in the VIII Latin American Biennial of Architecture and Urbanism, highlights the importance of collaboration with industry for the development and application of its outer membrane. The analysis of the construction process of the ceramic cylindrical curtain that defines it, performed by white glazed ceramic, 5 cm diameter and 7.5 m height, reveals this fact. The system builds an interstitial space, essential for its use and environmental integration. At the same time it links the building to both local industrial fabric, which aims to establish itself as one of its exponents, and to the Mediterranean culture of filters. The procedure followed is ascribed to the postartesanal and pragmatic perspective that beyond the modern heroes, introduced characters like Jean Prouvé and that today, we state, should find natural and legal channels for its development, on behalf of the progress of the construction sector.

Thirty beef carcasses were harvested and the foreshank of each side was independently positioned (cranial, natural, parallel, or caudal) 1h post-mortem to determine the effect of foreshank angle at rigor mortis on the sarcomere length and tenderness of six beef shoulder muscles. The infraspinatus (IS), pectoralis profundus (PP), serratus ventralis (SV), supraspinatus (SS), teres major (TM) and triceps brachii (TB) were excised 48 h post-mortem for Warner-Bratzler shear force (WBSF) and sarcomere length evaluations. All muscles except the SS had altered (P<0.05) sarcomere lengths between positions; the cranial position resulted in the longest sarcomeres for the SV and TB muscles whilst the natural position had longer sarcomeres for the PP and TM muscles. The SV from the cranial position had lower (P<0.05) shear than the caudal position and TB from the natural position had lower (P<0.05) shear than the parallel or caudal positions. Sarcomere length was moderately correlated (r=-0.63; P<0.01) to shear force. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available As the result of government’s initiative and future outlook in uprising the awareness towards the implementation of sustainable elements in construction industries, the Industrialized Building System (IBS is one of the approaches that had been introduced as an alternative to conventional building method and produce the new strategy of reducing the waste of materials in construction. The IBS approach is actively promoted through several strategies and incentives as an alternative to conventional building methods. Extensive uptakes of modern Information Communication Technology (ICT applications are able to support the different IBS processes for effective production. However, it is argued that ICT uptake at the organizational level needs to be regularly improved. Thus, this paper fulfills the need to identify the critical barriers to ICT employment and highlighting the ICT drivers in enhancing the IBS management process. Critical barriers and drivers to ICT uptake were identified through questionnaire survey with industry stakeholders and were analyzed using mean index and critical t-value with the use of SPSS software. The critical drivers are top management support and commitment and improving the availability of the technologies. The critical drivers which were identified are significant in ensuring the enhancement of ICT implementation. Hence, any system in place should avoid the highest ranked barriers or seek to alleviate their impact by focusing on the identified drivers in order to enhance implementation of ICT in IBS process management.

If small angle X-ray scattering (SAXS) utilizing the soft X-ray region is available, advanced and unique experiments, which differ from traditional SAXS methods, can be realized. For example, grazing-incidence small angle X-ray scattering (GISAXS) using hard X-ray is a powerful tool for understanding the nanostructure in both vertical and lateral directions of thin films, while GISAXS utilizing the tender X-ray region (SX-GISAXS) enables depth-resolved analysis as well as a standard GISAXS analysis in thin films. Thus, at BL-15A2 at the Photon Factory, a dedicated diffractometer for SX-GISAXS (above 2.1 keV) was constructed. This diffractometer is composed of four vacuum chambers and can be converted into the vacuum state from the sample chamber in front of the detector surface. Diffractions are clearly observed until 12th peak when measuring collagen by SAXS with an X-ray energy of 2.40 keV and a camera length of 825 mm. Additionally, we conducted the model experiment using SX-GISAXS with an X-ray energy of 2.40 keV to confirm that a poly(methyl methacrylate)-poly(n-butyl acrylate) block copolymer thin film has a microphase-separated structure in the thin film, which is composed of lamellae aligned both parallel and perpendicular to the substrate surface. Similarly, in a polystyrene-poly(methyl methacrylate) block copolymer thin film, SX-GISAXS with 3.60 keV and 5.73 keV revealed that hexagonally packed cylinders are aligned parallel to the substrate surface. The incident angle dependence of the first order peak position of the q{sub z} direction obtained from experiments at various incident X-ray energies agrees very well with the theoretical one calculated from the distorted wave Born approximation.

Application of coupled symbolic and numeric processing to an advanced scheduling system for plant construction

International Nuclear Information System (INIS)

Kobayashi, Yasuhiro; Takamoto, Masanori; Nonaka, Hisanori; Yamada, Naoyuki

1994-01-01

A scheduling system has been developed by integrating symbolic processing functions for constraint handling and modification guidance, with numeric processing functions for schedule optimization and evaluation. The system is composed of an automatic schedule generation module, interactive schedule revision module and schedule evaluation module. The goal of the problem solving is the flattening of the daily resources requirement throughout the scheduling period. The automatic schedule generation module optimizes the initial schedule according to the formulatable portion of requirement description specified in a predicate-like language. A planning engineer refines the near-goal schedule through a knowledge-based interactive optimization process to obtain the goal schedule which fully covers the requirement description, with the interactive schedule revision module and schedule evaluation module. A scheduling system has been implemented on the basis of the proposed problem solving framework and experimentally applied to real-world sized scheduling problems for plant construction. With a result of the overall plant construction scheduling, a section schedule optimization process is described with the emphasis on the symbolic processing functions. (author)

Mulder, Evert; de Jong, Tako P R; Feenstra, Lourens

2007-01-01

In The Netherlands, construction and demolition (C&D) waste is already to a large extent being reused, especially the stony fraction, which is crushed and reused as a road base material. In order to increase the percentage of reuse of the total C&D waste flow to even higher levels, a new concept has been developed. In this concept, called 'Closed Cycle Construction', the processed materials are being reused at a higher quality level and the quantity of waste that has to be disposed of is minimised. For concrete and masonry, the new concept implies that the material cycle will be completely closed, and the original constituents (clay bricks, gravel, sand, cement stone) are recovered in thermal processes. The mixed C&D waste streams are separated and decontaminated. For this purpose several dry separation techniques are being developed. The quality of the stony fraction is improved so much, that this fraction can be reused as an aggregate in concrete. The new concept has several benefits from a sustainability point of view, namely less energy consumption, less carbon dioxide emission, less waste production and less land use (for excavation and disposal sites). One of the most remarkable benefits of the new concept is that the thermal process steps are fuelled with the combustible fraction of the C&D waste itself. Economically the new process is more or less comparable with the current way of processing C&D waste. On the basis of the positive results of a feasibility study, currently a pilot and demonstration project is being carried out. The aim is to optimise the different process steps of the Closed Cycle Construction process on a laboratory scale, and then to verify them on a large scale. The results of the project are promising, so far.

Cognitive processes in criminal profile construction: a preliminary study.

Science.gov (United States)

Kocsis, Richard N; Middledorp, Jenny; Try, Andrew C

2005-12-01

This study undertook an empirically based examination of the cognitive processes associated with the accurate construction of a criminal psychological profile. This was accomplished by comparing the abilities of profilers and nonprofilers in two simulated profiling exercises that measured both profile accuracy and an individual's performance on various tests of memory and comprehension related to the case materials presented in each exercise. The results of these experiments suggest that an incremental relationship exists between comprehension of the case materials and accuracy of the profiles generated. In addition, the findings provide some tentative indications that the comprehension of case material in a narrative (i.e., written) format is an integral cognitive function to proficient profiling.

2017-12-01

Full Text Available The construction of projects is mostly symbolised by the extraordinary levels of unethical practices and this has ruined the image of the industry. The delivery of good quality infrastructure projects in some emerging economies is continuously, disrupted because of unethical practices. This paper was, initiated to identify the most dominant unethical practices in the construction of projects, using most recent and comprehensive literature ranging from 2011 to 2017. Twenty unethical practices in the construction of projects were, identified. From this, the study observed that the most dominant unethical practices are corruption, bribery and collusive tendering. The least unethical practices revealed by this study are the lack of safety, overstatement of capacity and falsification of experience. Findings indicate that in order to redesign the future landscape of the industry, there is need to educate the workforce on the effects of unethical practices as well as the need to implement stronger policies. Based on these findings, further empirical studies are necessary. This article also presents recent challenges and trends of unethical behaviour that needs acknowledgement in order to assist the construction industry. In conclusion, this study proposes twelve possible solutions that could assist the construction community in the reduction of unethical practices

Waste management is pressing very hard with alarming signals in construction industry. Concrete waste constituents major proportions of construction and demolition waste of 81% in Australia. To minimize concrete waste generated from construction activities, recycling concrete waste is one of the best methods to conserve the environment. This paper investigates concrete recycling implementation in construction. Japan is a leading country in recycling concrete waste, which has been implementing 98% recycling and using it for structural concrete applications. Hong Kong is developing concrete recycling programs for high-grade applications. Australia is making relatively slow progress in implementing concrete recycling in construction. Therefore, empirical studies in Australia, Hong Kong, and Japan were selected in this paper. A questionnaire survey and structured interviews were conducted. Power spectrum was used for analysis. It was found that "increasing overall business competitiveness and strategic business opportunities" was considered as the major benefit for concrete recycling from Hong Kong and Japanese respondents, while "rising concrete recycling awareness such as selecting suitable resources, techniques and training and compliance with regulations" was considered as the major benefit from Australian respondents. However, "lack of clients' support", "increase in management cost" and "increase in documentation workload, such as working documents, procedures and tools" were the major difficulties encountered from Australian, Hong Kong, and Japanese respondents, respectively. To improve the existing implementation, "inclusion of concrete recycling evaluation in tender appraisal" and "defining clear legal evaluation of concrete recycling" were major recommendations for Australian and Hong Kong, and Japanese respondents, respectively.

2015-12-01

This is the first paper of a series of two regarding the construction of data quality (DQ) assured repositories for the reuse of information on infant feeding from birth until two years old. This first paper justifies the need for such repositories and describes the design of a process to construct them from Electronic Health Records (EHR). As a result, Part 1 proposes a computational process to obtain quality-assured datasets represented by a canonical structure extracted from raw data from multiple EHR. For this, 13 steps were defined to ensure the harmonization, standardization, completion, de-duplication, and consistency of the dataset content. Moreover, the quality of the input and output data for each of these steps is controlled according to eight DQ dimensions: predictive value, correctness, duplication, consistency, completeness, contextualization, temporal-stability and spatial-stability. The second paper of the series will describe the application of this computational process to construct the first quality-assured repository for the reuse of information on infant feeding in the perinatal period aimed at the monitoring of clinical activities and research.

A Context-Driven Model for the Flat Roofs Construction Process through Sensing Systems, Internet-of-Things and Last Planner System

Science.gov (United States)

Andújar-Montoya, María Dolores

2017-01-01

The main causes of building defects are errors in the design and the construction phases. These causes related to construction are mainly due to the general lack of control of construction work and represent approximately 75% of the anomalies. In particular, one of the main causes of such anomalies, which end in building defects, is the lack of control over the physical variables of the work environment during the execution of tasks. Therefore, the high percentage of defects detected in buildings that have the root cause in the construction phase could be avoidable with a more accurate and efficient control of the process. The present work proposes a novel integration model based on information and communications technologies for the automation of both construction work and its management at the execution phase, specifically focused on the flat roof construction process. Roofs represent the second area where more defects are claimed. The proposed model is based on a Web system, supported by a service oriented architecture, for the integral management of tasks through the Last Planner System methodology, but incorporating the management of task restrictions from the physical environment variables by designing specific sensing systems. Likewise, all workers are integrated into the management process by Internet-of-Things solutions that guide them throughout the execution process in a non-intrusive and transparent way.

Dietary fibre-rich tender cluster beans (Cyamopsis tetragonoloba; CB) are known to exert beneficial cholesterol lowering influence. We examined the influence of a combination of dietary tender CB and garlic (Allium sativum) in reducing the cholesterol gallstone formation in mice. Cholesterol gallstones were induced in Swiss mice by feeding a high-cholesterol diet (HCD) for 10 wk. Dietary interventions were made with 10 per cent CB and 1 per cent garlic included individually or together along with HCD. A total of 100 mice were divided into five groups of 20 mice each. Dietary CB, garlic and CB+garlic reduced the formation of cholesterol gallstones by 44, 25 and 56 per cent, respectively, lowered cholesterol by 23-48, 16-24, and 24-58 in bile, serum, and liver, respectively. Cholesterol saturation index in bile and cholesterol: phospholipid ratio in circulation and hepatic tissue were significantly lowered by these dietary interventions, with highest beneficial effect from CB+garlic. Activities of hepatic cholesterol metabolizing enzymes were modulated by CB, garlic and CB+garlic. Elevation in lipid peroxides caused by HCD was also countered by these dietary interventions, the combination producing the highest effect. The results showed that the prevention of experimentally induced formation of cholesterol gallstones by dietary CB and garlic was due to decreased biliary cholesterol secretion and increased cholesterol saturation index. In addition of anti-lithogenic effect, dietary CB and garlic in combination had a beneficial antioxidant effect.

Use of the processed used tires in embankment construction is becoming an accepted way of beneficially recycling scrap tires due to shortages of natural mineral resources and increasing waste disposal costs. Using these used tires in construction requires an awareness of the properties and the limitations associated with their use. The main objective of this paper is to assess the different processing techniques on the mechanical properties of used tires-sand mixtures to improve the engineering properties of the available soil. In the first part, a literature study on the mechanical properties of the processed used tires such as tire shreds, tire chips, tire buffings and their mixtures with sand are summarized. In the second part, large-scale direct shear tests are performed to evaluate shear strength of tire crumb-sand mixtures where information is not readily available in the literature. The test results with tire crumb were compared with the other processed used tire-sand mixtures. Sand-used tire mixtures have higher shear strength than that of the sand alone and the shear strength parameters depend on the processing conditions of used tires. Three factors are found to significantly affect the mechanical properties: normal stress, processing techniques, and the used tire content.

To identify the most frequent causes of accidents in the construction sector in order to help safety practitioners in the task of prioritizing preventive actions depending on the stage of construction. Official accident investigation reports are analysed. A causation pattern is identified with the proportion of causes in each of the different possible groups of causes. Significant associations of the types of causes with accident mechanisms and construction stages have been identified. Significant differences have been found in accident causation depending on the mechanism of the accident and the construction stage ongoing. These results should be used to prioritize preventive actions to combat the most likely causes for each accident mechanism and construction stage.

Evaluation of sampling, cookery, and shear force protocols for objective evaluation of lamb longissimus tenderness.

Shackelford, S D; Wheeler, T L; Koohmaraie, M

2004-03-01

Experiments were conducted to compare the effects of two cookery methods, two shear force procedures, and sampling location within non-callipyge and callipyge lamb LM on the magnitude, variance, and repeatability of LM shear force data. In Exp. 1, 15 non-callipyge and 15 callipyge carcasses were sampled, and Warner-Bratzler shear force (WBSF) was determined for both sides of each carcass at three locations along the length (anterior to posterior) of the LM, whereas slice shear force (SSF) was determined for both sides of each carcass at only one location. For approximately half the carcasses within each genotype, LM chops were cooked for a constant amount of time using a belt grill, and chops of the remaining carcasses were cooked to a constant endpoint temperature using open-hearth electric broilers. Regardless of cooking method and sampling location, repeatability estimates were at least 0.8 for LM WBSF and SSF. For WBSF, repeatability estimates were slightly higher at the anterior location (0.93 to 0.98) than the posterior location (0.88 to 0.90). The difference in repeatability between locations was probably a function of a greater level of variation in shear force at the anterior location. For callipyge LM, WBSF was higher (P lamb LM chops cooked with the belt grill using a larger number of animals (n = 87). In Exp. 2, LM chops were obtained from matching locations of both sides of 44 non-callipyge and 43 callipyge carcasses. Chops were cooked with a belt grill and SSF was measured, and repeatability was estimated to be 0.95. Repeatable estimates of lamb LM tenderness can be achieved either by cooking to a constant endpoint temperature with electric broilers or cooking for a constant amount of time with a belt grill. Likewise, repeatable estimates of lamb LM tenderness can be achieved with WBSF or SSF. However, use of belt grill cookery and the SSF technique could decrease time requirements which would decrease research costs.

Until now, buildings regularly require more energy and provide less user quality in practice than was to be expected from the installed technology during the planning. That has structural reasons. The naerco research project has investigated this aspect and developed the success contracting concept: pre-defined energy and quality parameters are contracted out as part of a function-based tender. A contractor guarantees their realisation for 15 years. The contractual process also includes continual control of the agreed values and a bonus-malus system.

Privileging Younger Children's Voices in Research: Use of Drawings and a Co-Construction Process

Directory of Open Access Journals (Sweden)

Joanna Tay-Lim PhD Student

2013-02-01

Full Text Available The growing acknowledgement of the value of listening to children's views and experiences in social research, popularly termed as “listening to their voices,” brings with it methodological consequences. Regarding children as expert informants about their own lives carries with it the simultaneous call for researchers to be experts in developing and employing appropriate strategies that can effectively elicit the insights that children can bring to a research topic. With younger children, the use of participatory methodologies has been foregrounded as the key to unlocking their potential to contribute rich and useful perspectives to inform research into their lives. This article explores the usefulness of employing preschoolers' drawings within the context of a co-construction process to facilitate the children's construction of ideas and reinforce their voices in research. The case is made that the quality of the dialogical engagement is as important as the drawing itself, and both visual images and the verbal exchanges are central to the children's meaning-making process. In the co-construction process, both adult and child are (ideally equal players and the resulting dialogical process plays a major role in the constitution of the phenomena. The role of the researcher as the co-constructor can be a challenging one because it entails engaging and supporting children's views and the expression of these views. The discussion and illustrations from the first author's research projects contribute to the literature base on positioning preschool children as valid social actors in their communities. We operate through an ethos of empowerment of all participants, and aim for participatory research practice which has at its heart an active involvement in promoting the rights of children as citizens with voice and power.

Full Text Available This paper is based on the model Lindgreen (2001, upholding the relationship marketing should be approached in three dimensions: objectives, definition of constructs and tools, which enable better customer management within organizations. The objective was to determine the characteristics of relationship marketing as a key factor in the process of Customer Loyalty in the big construction of Manizales Colombia. From a joint perspective, methodology relies on instruments and qualitative and quantitative analysis of court. The results tend to confirm that developers recognize the importance of Relational Marketing but not raised as a policy or have not defined in its strategic plan; additionally, expressed lack of strategies for customer retention, however, these remain loyal because the construction work on meeting your needs, based on trust, commitment and communication. To conclude, the faithful customers perceive that construction does not periodically evaluate their satisfaction with the purchased product, also claim that they show little interest in understanding the perception, make personal meetings, making constant communication through phone calls and meet their tastes and preferences.

Constructal design of a blast furnace iron-making process based on multi-objective optimization

Liu, Xiong; Chen, Lingen; Feng, Huijun; Qin, Xiaoyong; Sun, Fengrui

2016-01-01

For the fixed total raw material cost and based on constructal theory and finite time thermodynamics, a BFIM (blast furnace iron-making) process is optimized by taking a complex function as optimization objective. The complex function is integrated with HM (hot metal) yield and useful energy of the BF (blast furnace). The optimal cost distribution of raw materials (namely “generalized optimal construct”) is obtained. The effects of some parameters, such as oxygen enrichment, blast temperature and pulverized coal dosage, on the optimization results are analyzed. The results show that the HM yield, useful energy and complex function are, respectively, increased by 3.13%, 2.66% and 2.90% after generalized constructal optimization. The utilization efficiencies of the BFG (blast furnace gas) and slag are 41.3% and 57.1%, respectively, which means that the utilization potentials of the BFG and slag can be further exploited. Increasing pulverized coal dosage and decreasing the agglomerate ratio can increase the complex function. The performance the BFIM process can be improved by adjusting the oxygen enrichment, blast temperature, blast dosage, pressure ratio of the Brayton cycle's air compressor and relative pressure drop of the air compressor inlet to their optimal values, respectively, which are new findings of this paper. - Highlights: • Constructal optimization of a blast furnace iron-making process is performed. • Finite time thermodynamic model of open Brayton cycle is adopted. • Weighting function is taken as optimization objective. • Optimal cost distribution of the raw materials is obtained.

2010-05-01

Full Text Available Proposal: As new demands from sustainable development, environmental requirements arise as another challenge to design process management. It is already known that companies which design buildings are usually exposed to many managerial difficulties. Faced to the environmental demands, these companies require new facilities to align environmental requirements to the business goals and to include them properly in design process. This paper is based on a case study in a construction company, which was developed through interviews and document analysis. It is intended to present a procedure for the project environmental requirements elicitation, organization and analysis, which is based on the requirements engineering (ER concepts. As results it was concluded that the ER concepts are useful for the environmental requirements integration into the design process and that strategic planning should give directions for the effective environmental requirements adherence. Moreover, a procedure for environmental requirements modeling is proposed. Key-words: Design process, Requirements management, Environmental requirements, Construction

Management of construction cost contingency covering upside and downside risks

Full Text Available Many contractors are of the opinion that adding contingency funds to the tender price of a project may lead to loss of the tender. This research is a trial to put an end to this incorrect opinion. A more mature attitude to risk would recognize that contingency exists to be spent in order to avoid or minimize threats and to exploit or maximize opportunities. This research proposes an approach for determination and monitoring of Cost Contingency Reserve (CCR for a project. Control of CCR is interfaced with Earned Value Management. Application to a real project is carried out. Post-mitigation simulations show that value of CCR is 2.88% of project cost but there is a potential saving due to opportunities. The project is monitored after eight months from its assumed start date with one assumed emergent risk. The final results are as follows: CCR is enough to cover project current and residual threats and the contractor has a considerable amount of money that will be transferred to his margin at project closure assuming the project will not be exposed to additional emergent risks. A contractor can balance project upside risks and its downsides to increase his chance to win tender of the project.

Full Text Available Coconut water is currently being considered as an elixir for patients suffering from diseases like dengue and malaria as well as chikungunia to provide hydration properties to the body. It has become a popular beverage for many people owing to its palatability and high mineral content. In this study, the growth, survival and fermentation performance of the probiotic bacterium Bacillus coagulans in coconut water was assessed in order to produce a novel non-dairy, probiotic beverage. The species was characterized on the basis of morphology, physiology and biochemical parameters and its probiotic attributes were assessed. Batch fermentations were carried out for 2 days at a constant 37°C, thereafter the samples were subjected to microbiological and chemical analysis. The results suggested that the specie produced lactic acid and was acid and bile tolerant. The pH and titratable acidity of probiotic fermented coconut water were found to be 4.4 and 0.53 % lactic acid, respectively. The viscosity of fermented coconut water increased significantly from an initial 5.13 mPa.s to 5.35 mPa.s because of the increase in soluble solids content due to exopolysaccharide production by B. coagulans during fermentation. Also, the overall acceptability score of probiotic coconut water was higher than tender coconut water, suggesting its feasibility for use as a probiotic beverage.

2017-10-01

Industrialized Building System (IBS) is one of the approaches that had been introduced as an alternative to conventional building method where it becomes the new strategy of enhancing the sustainable construction in current industries while spearheading a huge advancement of benefits with green constructions into the existing industries. The IBS approach is actively promoted through several strategies and incentives as an alternative to conventional building methods. Extensive uptakes of modern Information Communication Technology (ICT) applications are able to support the different IBS processes for effective production. However, it is argued that ICT uptake at the organisational level is still in its infancy. This raises the importance to identify critical inhibitors which are inhibing the effective uptake of ICT in the IBS production management process. Critical inhibitors to ICT uptake were identified through questionnaire survey with the IBS industry stakeholders. The mean index and critical t-values are generated with the use of the quantitative tool, Statistical Package for Social Sciences (SPSS). The top ten priority ranked inhibitors reflect the Cost, People and Process elements to ICT uptake. High costs in acquiring the technologies and resistance to change were some main concerns from the findings.

Saaltink, Rémon; Dekker, Stefan C.; Griffioen, Jasper; Wassen, Martin J.

2016-04-01

Interest is growing in using soft sediment as a building material in eco-engineering projects. Wetland construction in the Dutch lake Markermeer is an example: here the option of dredging some of the clay-rich lake-bed sediment and using it to construct 10.000 ha of wetland will soon go under construction. Natural processes will be utilized during and after construction to accelerate ecosystem development. Knowing that plants can eco-engineer their environment via positive or negative biogeochemical plant-soil feedbacks, we conducted a six-month greenhouse experiment to identify the key biogeochemical processes in the mud when Phragmites australis is used as an eco-engineering species. We applied inverse biogeochemical modeling to link observed changes in pore water composition to biogeochemical processes. Two months after transplantation we observed reduced plant growth and shriveling as well as yellowing of foliage. The N:P ratios of plant tissue were low and were affected not by hampered uptake of N but by enhanced uptake of P. Plant analyses revealed high Fe concentrations in the leaves and roots. Sulfate concentrations rose drastically in our experiment due to pyrite oxidation; as reduction of sulfate will decouple Fe-P in reducing conditions, we argue that plant-induced iron toxicity hampered plant growth, forming a negative feedback loop, while simultaneously there was a positive feedback loop, as iron toxicity promotes P mobilization as a result of reduced conditions through root death, thereby stimulating plant growth and regeneration. Given these two feedback mechanisms, we propose that when building wetlands from these mud deposits Fe-tolerant species are used rather than species that thrive in N-limited conditions. The results presented in this study demonstrate the importance of studying the biogeochemical properties of the building material and the feedback mechanisms between plant and soil prior to finalizing the design of the eco-engineering project.

2018-01-01

Full Text Available Recent research in the construction industry has focused on the reduction of CO2 emission using quantitative assessment of building life. However, most of this research has focused on the operational stage of a building’s life cycle. Few comprehensive studies of CO2 emissions during building construction have been performed. The purpose of this study is to analyze the CO2 emissions of an apartment housing during the construction process. The quantity of CO2 emissions associated with the utilization of selected building materials and construction equipment were used to estimate the CO2 emissions related to the apartment housing life cycle. In order to set the system boundary for the construction materials, equipment, and transportation used, 13 types of construction work were identified; then the CO2 emissions produced by the identified materials were calculated for each type of construction work. The comprehensive results showed that construction work involving reinforced concrete accounted for more than 73% of the total CO2 emissions. The CO2 emissions related to reinforced concrete work was mainly due to transportation from the supplier to the construction site. Therefore, at the time that reinforced concrete is being supplied, shipping distance and fuel economy management of concrete transportation vehicles should be considered thoroughly for significant reduction of CO2 emissions.

Aminbakhsh, Saman; Gunduz, Murat; Sonmez, Rifat

2013-09-01

The inherent and unique risks on construction projects quite often present key challenges to contractors. Health and safety risks are among the most significant risks in construction projects since the construction industry is characterized by a relatively high injury and death rate compared to other industries. In construction project management, safety risk assessment is an important step toward identifying potential hazards and evaluating the risks associated with the hazards. Adequate prioritization of safety risks during risk assessment is crucial for planning, budgeting, and management of safety related risks. In this paper, a safety risk assessment framework is presented based on the theory of cost of safety (COS) model and the analytic hierarchy process (AHP). The main contribution of the proposed framework is that it presents a robust method for prioritization of safety risks in construction projects to create a rational budget and to set realistic goals without compromising safety. The framework provides a decision tool for the decision makers to determine the adequate accident/injury prevention investments while considering the funding limits. The proposed safety risk framework is illustrated using a real-life construction project and the advantages and limitations of the framework are discussed.

Time-dependent structure analysis theory has been proved to be more accurate and reliable com-pared to commonly used methods during construction. However, so far applications are limited to partial pe-riod and part of the structure because of immeasurable artificial intervention. Based on the building informa-tion model (BIM) and four-dimensional (4D) technology, this paper proposes an improves structure analysis method, which can generate structural geometry, resistance model, and loading conditions automatically by a close interlink of the schedule information, architectural model, and material properties. The method was applied to a safety analysis during a continuous and dynamic simulation of the entire construction process.The results show that the organic combination of the BIM, 4D technology, construction simulation, and safety analysis of time-dependent structures is feasible and practical. This research also lays a foundation for further researches on building lifecycle management by combining architectural design, structure analy-sis, and construction management.

Boneless beef rib eye roasts were surface inoculated on the fat side with ca. 5.7 log CFU/g of a five-strain cocktail of Salmonella for subsequent searing, cooking, and warm holding using preparation methods practiced by restaurants surveyed in a medium-size Midwestern city. A portion of the inoculated roasts was then passed once through a mechanical blade tenderizer. For both intact and nonintact roasts, searing for 15 min at 260°C resulted in reductions in Salmonella populations of ca. 0.3 to 1.3 log CFU/g. For intact (nontenderized) rib eye roasts, cooking to internal temperatures of 37.8 or 48.9°C resulted in additional reductions of ca. 3.4 log CFU/g. For tenderized (nonintact) rib eye roasts, cooking to internal temperatures of 37.8 or 48.9°C resulted in additional reductions of ca. 3.1 or 3.4 log CFU/g, respectively. Pathogen populations remained relatively unchanged for intact roasts cooked to 37.8 or 48.9°C and for nonintact roasts cooked to 48.9°C when held at 60.0°C for up to 8 h. In contrast, pathogen populations increased ca. 2.0 log CFU/g in nonintact rib eye cooked to 37.8°C when held at 60.0°C for 8 h. Thus, cooking at low temperatures and extended holding at relatively low temperatures as evaluated herein may pose a food safety risk to consumers in terms of inadequate lethality and/or subsequent outgrowth of Salmonella, especially if nonintact rib eye is used in the preparation of prime rib, if on occasion appreciable populations of Salmonella are present in or on the meat, and/or if the meat is not cooked adequately throughout.

The organocatalytic generation of a strong base by the action of a good nucleophile is the base for the in situ catalytic generation of conjugated acetylides in the presence of aldehydes or activated ketones. The method is affordable in a multicomponent, domino format able to generate a chemically diverse set of multifunctionalized adducts that are very well suited for diversity-oriented molecular construction. The domino process involves a nucleophile as catalyst and a terminal conjugated alkyne (H-C[triple chemical bond]C-Z) and an aldehyde or activated ketone as building blocks. The chemical outcome of this process changes dramatically as a function of the nucleophile (tertiary amine or phosphine), temperature, stoichiometry, and solvent. These multicomponent domino processes achieve molecular construction with good atom economy and, very importantly, with an exquisite chemo-differentiating incorporation of identical starting units into the products (nondegenerated chemical output). These properties convert the H-C[triple chemical bond]C-Z unit into a specific building block for diversity-oriented molecular construction. Applications to the modular and diversity-oriented synthesis of relevant heterocycles are discussed. A protocol involving two coupled domino processes linked in a one-pot manner will be discussed as an efficient synthetic manifold for the modular and diversity-oriented construction of multisubstituted nitrogen-containing heterocycles.

2013-03-01

Full Text Available Cost is one of the major considerations throughout the project management life cycle and can be regarded as one of the most important parameters of a project and the driving force of project success. Despite its proven importance, it is common to see a construction project failing to achieve its objectives within the specific cost. Cost variation is a very frequent phenomenon and is almost associated with nearly constructing all wastewater projects. Maintaining steady cost projection on wastewater projects had been recently an issue of serious concern, both to the client and project contractors. Cost deviation from initial cost plan had been prevalent on construction sites. However, little or no effort has been made to curtail the phenomenon, this research work attempts to identify, investigate and rank factors perceived to affect cost variation in the Egyptian wastewater projects with respect to their relative importance so as to proffer possible ways of coping with this phenomenon. To achieve this objective, author invited practitioners and experts, comprising a statistically representative sample, to participate in a structured questionnaire survey. Brain storming was taken into consideration, through which a number of cost variation factors were identified for constructing wastewater projects. Totally 52 factors were short-listed to be made part of the questionnaire survey and the survey was conducted with experts and representatives from private, public and local general construction firms. The data were analyzed using Relative Importance Index, ranking and simple percentages. It was analytically discovered that factors such as: (1 Lowest bidding procurement method; (2 Additional work; (3 Bureaucracy in bidding/tendering method; (4 Wrong method of cost estimation; and (5 Funding problems were critical for causing cost variation, while (1 Inaccurate cost estimation; (2 Mode of financing and payment for completed work; (3 Unexpected ground

Fibromyalgia is a chronic pain syndrome associated with sleep disorders, fatigue and psychological symptoms. Combinations therapies, such as electrotherapy and therapeutic exercises have been used in the clinical practice. To assess the efficacy of high-frequency transcutaneous electrical nerve stimulation (TENS) as an adjuvant therapy to aerobic and stretching exercises, for the treatment of fibromyalgia. Controlled clinical trial. Unit of rehabilitation of a public hospital. Twenty-eight women aged 52.4±7.5 years, with fibromyalgia. A visual analogue scale measured pain intensity; tender points pain threshold, by dolorimetry; and quality of life, by the Fibromyalgia Impact Questionnaire. All subjects participated in an eight-week program consisting of aerobic exercises, followed by static stretching of muscle chains. In TENS group, high-frequency (150 Hz) was applied on bilateral tender points of trapezium and supraspinatus. TENS group had a greater pain reduction (mean change score=-2.0±2.9 cm) compared to Without TENS group (-0.7±3.7 cm). There was a difference between mean change scores of each group for pain threshold (right trapezium: 0.2±1 kg/cm² in TENS group and -0.2±1.2 kg/cm² in Without TENS group). In the evaluation of clinically important changes, patients receiving TENS had relevant improvement of pain, work performance, fatigue, stiffness, anxiety and depression compared to those not receiving TENS. It has suggested that high-frequency TENS as an adjuvant therapy is effective in relieving pain, anxiety, fatigue, stiffness, and in improving ability to work of patients with fibromyalgia. High-frequency TENS may be used as a short-term complementary treatment of fibromyalgia.

Uusitalo, K.,

2008-01-01

Full Text Available Process-based thinking commonly focuses on enhancing the efficiency of processes, while it is often criticized for not paying enough attention to the customer. This paper argues that customer complaint information can be used as a basis for customer-focused process improvement. Thus, it is not enough to make the complaining customer satisfied, but the complaint information should also feed back to the actual processes where the fault causing the complaint arose and where it can be removed. The empirical component of the study includes the development of a novel construction to utilize customer complaints for process improvements, which was implemented in a large Finnish enterprise operating in the wholesale logistics environment. The results show benefits at both operational and strategic levels.

2017-04-01

Full Text Available For generations, the process of cost estimation has been manual, time-consuming and error-prone. Emerging Building Information Modelling (BIM can exploit standard measurement methods to automate cost estimation process and improve inaccuracies. Structuring standard measurement methods in an ontologically and machine readable format for a BIM software can greatly facilitate the process of improving inaccuracies in cost estimation. This study explores the development of an ontology based on New Rules of Measurement (NRM for cost estimation during the tendering stages. The methodology adopted is methontology, one of the most widely used ontology engineering methodologies. To ensure the ontology is fit for purpose, cost estimation experts are employed to check the semantics, descriptive logic-based reasoners are used to syntactically check the ontology and a leading 4D BIM modelling software is used on a case study building to test/validate the proposed ontology.

The following four principles are included in the measures to be taken for efficient execution of the construction work within the short construction period: (1) reduction of on-site work and expansion of module block making, (2)improvement of the accuracy of the on-site work process, adjustment and expansion of the work in parallel with the construction process, (3)improvement of efficiency of the on-site work and mechanization and automation of the work, (4)improvement of the accuracy of the management of the construction. A three dimensional simulation system plant construction plan CAE, comprising five modules has been developed. A project management system was also developed to improve the accuracy and efficiency of management work in the field

Decision concerning Hydro-Quebec's request to rescind the need to go to tender to fulfill the electricity needs of bi-energy rate commercial, institutional and industrial (BT rate) consumers, article 74.1 of la Loi sur la Regie de l'energie

International Nuclear Information System (INIS)

Patoine, M.A.

2002-01-01

In 1983 Hydro-Quebec initiated a special rate for commercial, institutional and industrial power consumers that made use of dual energy systems to heat and power their facilities. In October 2001, Hydro-Quebec made a request to the Regie to rescind the preferential bi-energy rate for commercial, institutional and industrial consumers. The report presents Hydro-Quebec's justification for this request with particular reference to the problems related with going to tender. The contents of the agreement between distributors and power producers were also revealed with respect to short term contracts. The report also presents the position and comments of the interveners with particular reference to the consequences of rescinding the need to go to tender. The opinion of the Regie de l'energie went in favour of the interveners. The Regie denied the request to rescind the need for tender to satisfy the electricity needs of subscribers of the preferential bi-energy rate for commercial, institutional and industrial consumers. refs., tabs

Simulation-Based Prediction of Equivalent Continuous Noises during Construction Processes.

Science.gov (United States)

Zhang, Hong; Pei, Yun

2016-08-12

Quantitative prediction of construction noise is crucial to evaluate construction plans to help make decisions to address noise levels. Considering limitations of existing methods for measuring or predicting the construction noise and particularly the equivalent continuous noise level over a period of time, this paper presents a discrete-event simulation method for predicting the construction noise in terms of equivalent continuous level. The noise-calculating models regarding synchronization, propagation and equivalent continuous level are presented. The simulation framework for modeling the noise-affected factors and calculating the equivalent continuous noise by incorporating the noise-calculating models into simulation strategy is proposed. An application study is presented to demonstrate and justify the proposed simulation method in predicting the equivalent continuous noise during construction. The study contributes to provision of a simulation methodology to quantitatively predict the equivalent continuous noise of construction by considering the relevant uncertainties, dynamics and interactions.

Same but different: Comparative modes of information processing are implicated in the construction of perceptions of autonomy support.

An implicit assumption behind tenets of self-determination theory is that perceptions of autonomy support are a function of absolute modes of information processing. In this study, we examined whether comparative modes of information processing were implicated in the construction of perceptions of autonomy support. In an experimental study, we demonstrated that participants employed comparative modes of information processing in evaluating receipt of small, but not large, amounts of autonomy support. In addition, we found that social comparison processes influenced a number of outcomes that are empirically related to perceived autonomy support such as sense of autonomy, positive affect, perceived usefulness, and effort. Findings shed new light upon the processes underpinning construction of perceptions related to autonomy support and yield new insights into how to increase the predictive validity of models that use autonomy support as a determinant of motivation and psychological well-being. © 2017 The British Psychological Society.

Sineeva, Natalya

2018-03-01

Our study relevance is due to the increasing man-made impact on water bodies and associated land resources within the urban areas, as a consequence, by a change in the morphology and dynamics of Rivers' canals. This leads to the need to predict the development of erosion-accumulation processes, especially within the built-up urban areas. Purpose of the study is to develop programs on the assessment of erosion-accumulation processes at a water body, a mouth area of the Inia River, in the of perspective high-rise construction zone of a residential microdistrict, the place, where floodplain-channel complex is intensively expected to develop. Results of the study: Within the velocities of the water flow comparing, full-scale measured conditions, and calculated from the model, a slight discrepancy was recorded. This allows us to say that the numerical model reliably describes the physical processes developing in the River. The carried out calculations to assess the direction and intensity of the channel re-formations, made us possible to conclude, there was an insignificant predominance of erosion processes over the accumulative ones on the undeveloped part of the Inia River (the processes activity is noticeable only in certain areas (by the coasts and the island)). Importance of the study: The study on the erosion-accumulation processes evaluation can be used in design decisions for the future high-rise construction of this territory, which will increase their economic efficiency.

Stancu, F.; Wilets, L.

1987-01-01

The work presented is to classify and construct six-quark states as totally antisymmetric states of six fermions, each described by orbital, spin, isospin, and color degrees of freedom. A classification scheme is proposed based on parity eigenfunctions. The single-particle hamiltonian is assumed to be reflectionally and axially symmetric and can be obtained, for example, from constrained Hartree-Fock or solition mean field theories. The ultimate aim is to study N-N processes in the context of the (relativistic) soliton bag model

Confirming and denying in co-construction processes: a case study of an adult with cerebral palsy and two familiar partners.

Science.gov (United States)

Hörmeyer, Ina; Renner, Gregor

2013-09-01

For individuals with complex communication needs, one of the most frequent communicative strategies is the co-construction of meaning with familiar partners. This preliminary single-case study gives insight into a special sequential pattern of co-construction processes - the search sequence - particularly in relation to the processes of confirming and denying meanings proposed by familiar interaction partners. Five different conversations between an adult with cerebral palsy and complex communication needs and two familiar co-participants were videotaped and analyzed using the methodology of conversation analysis (CA). The study revealed that confirmations and denials are not simply two alternative actions, but that several possibilities to realize confirmations and denials exist that differ in their frequency and that have different consequences for the sequential context. This study of confirmations and denials demonstrates that co-construction processes are more complex than have previously been documented.

MULTI-MARKET INDUSTRIAL ORGANIZATIONAL ECONOMIC MODELS FOR THE INTERNATIONALIZATION PROCESS BY SMALL AND MEDIUM ENTERPRISE CONSTRUCTION DESIGN SERVICE FIRMS

Directory of Open Access Journals (Sweden)

Kerry London

2010-11-01

Full Text Available Small and medium enterprises (SMEs are critical to strategic initiatives in an economy; however, their contribution to foreign trade is not as significant. SMEs are one of the principal driving forces in economic development. One of the greatest challenges is the internationalization process for longevity rather than seeing the process as initial market entry. The internationalization process research has typically involved four key constructs: market selection, decision to enter, entry modes and factors affecting entry modes. Past research has focused on large manufacturing firms. The export of architectural, engineering and construction (AEC firms has undergone growth, yet there is still significant opportunity for further growth. The majority of AEC firms are SMEs. Notwithstanding assistance provided through international trade missions, organized export firm support networks and information packages by a burgeoning number of government agencies, there are still perceived barriers to market entry and long-term economic sustainability for SMEs. There are a number of problems faced by SMEs acting in foreign trade. This investigation explores the successful initial internationalization process constructs and identifies unique project-oriented sector characteristics. The study identified similarities and differences between two firms that have been exporting to various localities, including Eastern Europe, Africa, Middle East, UK, Asia and South America, for more than two decades. The similarities and differences were identified within eight major constructs: purpose, firm type, market image and design philosophy, entry mode strategy, institutional arrangement, factors affecting mode of entry, market selection and firm strategy in relation to project selection. The primary reasons for internationalization were associated with the firms' motivations related to growth and financial viability. This article discusses the various internationalization

[On-line processing mechanisms in text comprehension: a theoretical review on constructing situation models].

Science.gov (United States)

Iseki, Ryuta

2004-12-01

This article reviewed research on construction of situation models during reading. To position variety of research in overall process appropriately, an unitary framework was devised in terms of three theories for on-line processing: resonance process, event-indexing model, and constructionist theory. Resonance process was treated as a basic activation mechanism in the framework. Event-indexing model was regarded as a screening system which selected and encoded activated information in situation models along with situational dimensions. Constructionist theory was considered to have a supervisory role based on coherence and explanation. From a view of the unitary framework, some problems concerning each theory were examined and possible interpretations were given. Finally, it was pointed out that there were little theoretical arguments on associative processing at global level and encoding text- and inference-information into long-term memory.

Science.gov (United States)

Ma, Yukun; Gong, Manli; Zhao, Hongtao; Li, Xuyong

2018-02-01

Intense Low-Impact Development (LID) construction in China could lead to increasingly severe stormwater and receiving water pollution due to the lack of appropriate regulation for mitigating pollution from LID construction. Samples of road-deposited sediments (RDS) were collected from 50 study sites at seven LID construction stages and four road hierarchies to analyze the pollution process and determine the size of the region influenced by LID construction. Six heavy metals were analyzed, and the RDS index model was adopted to estimate the potential heavy metal load washed off by stormwater runoff. Analysis of variance revealed that the excavation and gravel filling of rain gardens and excavation of porous pavements were critical LID construction stages that contributed the largest masses of RDS per unit area to road surfaces. Although the concentration of heavy metals at LID construction sites was lower than at sites without LID construction, the load of heavy metals washed off from LID construction was much higher. In addition, the sizes of regions influenced by accumulated RDS from LID construction descended in the following order: arterial road (600-775m)>collector road (150-200m)>access road (100-150m)>laneway (20-30m). According to the characteristics of LID construction at the study sites, the potential total solid loads in stormwater throughout China were estimated to reach 36,694t by 2020 and 146,777t by 2030. According to the results of analysis, several recommendations are provided for designing LID construction regulations to mitigate stormwater pollution. Copyright © 2017 Elsevier B.V.

CONSIDERATIONS UPON DESIGNING MODULAR CONSTRUCTIONS FOR IMPROVING THE PRODUCTS ASSEMBLING, MAINTENANCE AND RECYCLING PROCESSES

Directory of Open Access Journals (Sweden)

BÂRSAN Lucian

2015-11-01

Full Text Available Modular constructions are frequently used in industry because of their multiple advantages. Used from the antiquity as a measuring system that ensured good proportions for the objects or buildings, the module is used in present industry as a tool for improving the product maintenance, repair, upgrading, and/or recycling. Modular constructions can be assembled and disassembled easily, facilitating the postuse actions like subassemblies reuse, or materials recovering for the recycling process. An important aspect of this paper is that designers should create the modular solution even from the conceptual design stage and build a structure of functions based on well motivated arguments and which can easily be brake out according to technological possibilities, product functioning and assembly solutions.

Causative get-constructions in the dialogued passages in F. Scott Fitzgerald’s novels The Beautiful and Damned and Tender Is the Night as gender-conditioned structures

Directory of Open Access Journals (Sweden)

Gołąbek Rafał

2015-05-01

Full Text Available It goes without saying that in modern sociolinguistics there is a consensus with regard to the fact that the language of males and females differs. The initial sections of the article briefly address the peculiarities of gendered speech as to provide a theoretical background for checking whether the causative get is used similarly or differently by men and women in the two of F. Scott Fitzgerald’s novels: The Beautiful and Damned and Tender Is the Night. The basic expectation formed is that the motifs for triggering the use of causative get are of social rather than structural nature. Before the analysis is carried out, the group of the English periphrastic causatives are sketchily characterized. Generally, what has been found is that there is a clear, socially-motivated pattern of how F. Scott Fitzgerald uses the causative get in the dialogued occurrences in his two novels. Get is a characteristic of men’s talk, but it is also the expected form while female characters address male ones - hence the verb is labelled as “masculine” get. Moreover, it has been discovered that there does not seem to be any particular pattern in either the speaker’s mood or the speaker’s attitude expressed that would trigger the use of the causative verb in question. Yet, what seems to be a well-defined tendency, when it comes to the speaker-hearer power relation, is that the speaker usually assumes a more superior position than the hearer when he or she uses the causative verb. The superiority in most cases is strongly associated with masculinity. Hence, what is postulated is that the causative get is labelled not only as “masculine" but also as “superior”.

Reindeer meat – is it always tender, tasty and healthy?

Directory of Open Access Journals (Sweden)

Eva Wiklund

2007-04-01

Full Text Available Meat with high pH values, so called DFD (Dark, Firm, Dry meat, is a persistent quality defect foundmin all meat species. DFD shortens shelf life, especially for vacuum-packed meat and affects meat colour, tenderness and water-holding properties. High pH values in reindeer meat have been related to pre-slaughter handling stress and poor nutritional status of the animals. There are numerous reports that variation in muscle pH and glycogen content give rise to considerable variations in meat tenderness in species such as beef and lamb. In contrast, reindeer meat has been found to be extremely tender regardless of ultimate pH. This phenomenon has been related to the speed of post mortem protein degradation and the small muscle fibre size in reindeer. Previous research has demonstrated that the fatty acid composition of meat changes in response to diets. Generally, a higher proportion of long, unsaturated fatty acids were found in meat from grazing animals compared with animals fed a grain-based diet. Reindeer meat has been found to contain moderate amounts of polyunsaturated fatty acids (PUFA, especially so-called n-3 (or omega-3 PUFAs. The PUFAs are known to be susceptible to oxidation and may therefore be easily oxidized during processing by techniques like smoking and drying. A trained sensory panel concluded that meat from reindeer fed commercial feed scored higher for liverish and sweet flavours and lower for off-flavou (i.e. ‘grass’, ‘wild’ and ‘game’ compared with meat from grazing animals. Consumer preference tests on reindeer meat showed that 50 per cent of the consumers preferred meat from grazing reindeer and 50 per cent meat from pellet-fed animals. Recent reindeer meat research has included new feed mixtures using ingredients like linseed and fishmeal. Crushed linseed in the feed gave meat with a fat composition similar to that of natural pasture, which meant more PUFA than in meat from reindeer fed the normal grain

The outcome of construction projects highly depends on effective management. The site manager is responsible for the site, and has a key role in executing construction projects. Especially this position has a wide range of tasks and a high volume of workload, which has to be carried out in a high pressure and high stress environment. Chaotic construction processes often create these working conditions. Lean Construction can help to organize the construction site in a better way and automatically supports the site manager.

Describing complex mammography examination processes is important for improving the quality of mammograms. It is often difficult for experienced radiologic technologists to explain the process because their techniques depend on their experience and intuition. In our previous study, we analyzed the process using a new bottom-up hierarchical task analysis and identified key components of the process. Leveraging the results of the previous study, the purpose of this study was to construct a mammographic examination process ontology to formally describe the relationships between the process and image evaluation criteria to improve the quality of mammograms. First, we identified and created root classes: task, plan, and clinical image evaluation (CIE). Second, we described an "is-a" relation referring to the result of the previous study and the structure of the CIE. Third, the procedural steps in the ontology were described using the new properties: "isPerformedBefore," "isPerformedAfter," and "isPerformedAfterIfNecessary." Finally, the relationships between tasks and CIEs were described using the "isAffectedBy" property to represent the influence of the process on image quality. In total, there were 219 classes in the ontology. By introducing new properties related to the process flow, a sophisticated mammography examination process could be visualized. In relationships between tasks and CIEs, it became clear that the tasks affecting the evaluation criteria related to positioning were greater in number than those for image quality. We developed a mammographic examination process ontology that makes knowledge explicit for a comprehensive mammography process. Our research will support education and help promote knowledge sharing about mammography examination expertise.

Effect of Ginger Extract and Citric Acid on the Tenderness of Duck Breast Muscles

Science.gov (United States)

2015-01-01

The objective of this study was to examine the effect of ginger extract (GE) combined with citric acid on the tenderness of duck breast muscles. Total six marinades were prepared with the combination of citric acid (0 and 0.3 M citric acid) and GE (0, 15, and 30%). Each marinade was sprayed on the surface of duck breasts (15 mL/100 g), and the samples were marinated for 72 h at 4℃. The pH and proteolytic activity of marinades were determined. After 72 h of marination, Warner Bratzler shear force (WBSF), myofibrillar fragmentation index (MFI), pH, cooking loss, moisture content, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and protein solubility were evaluated. There was no significant (p>0.05) difference in moisture content or cooking loss among all samples. However, GE marination resulted in a significant (pcitric acid) and WC (with citric acid) conditions were significantly (pcitric acid may be attributed to various mechanisms such as increased MFI and myofibrillar protein solubility.

In this study, the effect of pulsed electric field (PEF) treatment and ageing on the quality of beef M. longissimus lumborum (LL) and M. semimembranosus (SM) muscles was evaluated, including the tenderness, water loss and post-mortem proteolysis. Muscles were obtained from 12 steers (6 steers for each muscle), removed from the carcasses 4 hour postmortem and were treated with pulsed electric field within 2h. Six different pulsed electric field intensities (voltages of 5 and 10 kV × frequencies of 20, 50 and 90 Hz) plus a control were applied to each muscle to determine the optimum treatment conditions. Beef LL was found to get tougher with increasing treatment frequency whereas beef SM muscle was found to have up to 21.6% reduction in the shear force with pulsed electric field treatment. Post-mortem proteolysis showed an increase in both troponin and desmin degradation in beef LL treated with low intensity PEF treatment (20 Hz) compared to non-treated control samples.

Evaluation of pain sensitivity by tender point counts and myalgic score in patients with and without obstructive sleep apnea syndrome.

Science.gov (United States)

Terzi, Rabia; Yılmaz, Zahide

2017-03-01

The purpose of this study was to assess the difference between patients with and without obstructive sleep apnea syndrome (OSAS) with respect to pain sensitivity. The study was conducted on 31 womens diagnosed with OSAS and 31 healthy women. All patients underwent polysomnographic testing. A pressure algometer (dolorimeter) was used to measure the pressure pain threshold. Fibromyalgia was diagnosed based on the 1990 American College of Rheumatology diagnosis criteria. The myalgic score was 73.95 ± 18.09 in patients with OSAS, while this value was 84.18 ± 24.31 in the control group. The difference between the groups was statistically significant (P = 0.041).The number of tender points was 8.19 ± 3.35 in the patient group with OSAS, while this number was 6.35 ± 2.23 in the control group. The difference between the two groups was statistically significant (P = 0.014). No statistically significant differences were found between age, body mass index, Beck depression scores, control point score and the presence of fibromyalgia, between the two groups (P > 0.05). A statistically significant positive correlation was found between the myalgic scores and mean saturation O 2 (%) values of the patients (r = 0.357; P = 0.049). The differences noted between OSAS patients and the control group with respect to myalgic score and the number of tender points suggest that there might be a relation between OSAS and pain sensitivity. There might be an association between low oxygen saturation and total myalgic score. © 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

The tenderness and palatability of retail and food service beef steaks from across the United States (12 cities for retail, 5 cities for food service) were evaluated using Warner-Bratzler shear (WBS) and consumer sensory panels. Subprimal postfabrication storage or aging times at retail establishments averaged 20.5 d with a range of 1 to 358 d, whereas postfabrication times at the food service level revealed an average time of 28.1 d with a range of 9 to 67 d. Approximately 64% of retail steaks were labeled with a packer/processor or store brand. For retail, top blade had among the lowest (P 0.05) in WBS values between moist-heat and dry-heat cookery methods for the top round and bottom round steaks or between enhanced (contained salt or phosphate solution) or nonenhanced steaks. Food service top loin and rib eye steaks had the lowest (P food service top loin steaks received among the greatest (P food service rib eye steaks received the greatest ratings (P food service steaks were greater (P Choice, and Low Choice groups. The WBS values and sensory ratings were comparable to the last survey, signifying that no recent or substantive changes in tenderness have occurred.

A Construction Management Framework for Mass Customisation in Traditional Construction

Directory of Open Access Journals (Sweden)

María Dolores Andújar-Montoya

2015-04-01

Full Text Available A Mass Customisation model is discussed as a competitive positioning strategy in the marketplace adding value to the customer’s end-use. It includes the user as part of the construction process responding to the customer’s demands and wishes. To the present day, almost all proposals for Mass Customisation have been focused on the design phase and single family houses. The reality is that the processes carried out in the work execution are so inefficient that the costs of the Mass Customisation models are assumed by the customer and they do not offer solutions that support the change management. Furthermore, this inefficiency often makes Mass Customisation unfeasible in terms of deadlines and site management. Therefore, the present proposal focuses on achieving the paradigm of Mass Customisation in the traditional residential construction complementary to the existing proposals in the design phase. All this through the proposal of a framework for the integral management in the work execution, which will address change management introduced by the users offering an efficient and productive model that reduces costs in the process. This model will focus on the synergy between different strategies, techniques and technologies currently used in the construction management (such as Lean Construction or Six Sigma, together with, other strategies and technologies that have proven to be valid solutions in other fields (such as Business Process Management, Service Oriented Architecture, etc..

Quantitative analysis method for ship construction quality

Directory of Open Access Journals (Sweden)

FU Senzong

2017-03-01

Full Text Available The excellent performance of a ship is assured by the accurate evaluation of its construction quality. For a long time, research into the construction quality of ships has mainly focused on qualitative analysis due to a shortage of process data, which results from limited samples, varied process types and non-standardized processes. Aiming at predicting and controlling the influence of the construction process on the construction quality of ships, this article proposes a reliability quantitative analysis flow path for the ship construction process and fuzzy calculation method. Based on the process-quality factor model proposed by the Function-Oriented Quality Control (FOQC method, we combine fuzzy mathematics with the expert grading method to deduce formulations calculating the fuzzy process reliability of the ordinal connection model, series connection model and mixed connection model. The quantitative analysis method is applied in analyzing the process reliability of a ship's shaft gear box installation, which proves the applicability and effectiveness of the method. The analysis results can be a useful reference for setting key quality inspection points and optimizing key processes.

Ecological studies related to construction of the Defense Waste Processing Facility on the Savannah River Site

Energy Technology Data Exchange (ETDEWEB)

Pechmann, J.H.K.; Scott, D.E.; McGregor, J.H.; Estes, R.A.; Chazal, A.C.

1993-02-01

The Defense Waste Processing Facility (DWPF) was built on the Savannah River Site (SRS) during the mid-1980's. The Savannah River Ecology Laboratory (SREL) has completed 12 years of ecological studies related to the construction of the DWPF complex. Prior to construction, the 600-acre site (S-Area) contained a Carolina bay and the headwaters of a stream. Research conducted by the SREL has focused primarily on four questions related to these wetlands: (1) Prior to construction, what fauna and flora were present at the DWPF site and at similar, yet undisturbed, alternative sites (2) By comparing the Carolina bay at the DWPF site (Sun Bay) with an undisturbed control Carolina bay (Rainbow Bay), what effect is construction having on the organisms that inhabited the DWPF site (3) By comparing control streams with streams on the periphery of the DWPF site, what effect is construction having on the peripheral streams (4) How effective have efforts been to lessen the impacts of construction, both with respect to erosion control measures and the construction of refuge ponds'' as alternative breeding sites for amphibians that formerly bred at Sun Bay Through the long-term census-taking of biota at the DWPF site and Rainbow Bay, SREL has begun to evaluate the impact of construction on the biota and the effectiveness of mitigation efforts. Similarly, the effects of erosion from the DWPF site on the water quality of S-Area peripheral streams are being assessed. This research provides supporting data relevant to the National Environmental Policy Act (NEPA) of 1969, the Endangered Species Act of 1973, Executive Orders 11988 (Floodplain Management) and 11990 (Protection of Wetlands), and United States Department of Energy (DOE) Guidelines for Compliance with Floodplain/Wetland Environmental Review Requirements (10CFR1022).

Energy-Performance-Based Design-Build Process: Strategies for Procuring High-Performance Buildings on Typical Construction Budgets: Preprint

Energy Technology Data Exchange (ETDEWEB)

Scheib, J.; Pless, S.; Torcellini, P.

2014-08-01

NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner's representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.

Van Der Schaaf, B.; De Jong, P.

2010-01-01

In the European Union the first generation research reactors is nearing their end of life condition. Several committees recommend a comprehensive set of reactors in the EU, amongst them the replacement for the HFR research and isotope reactor in Petten: PALLAS. The business case for PALLAS supports a future for a research and isotope reactor in Petten as a perfect fit for the future EU set of test reactors. The tender for PALLAS started in 2007, following the EU rules for tendering complex objects with the competitive dialogue. This procedure involved an extensive consultation phase between individual tendering companies and NRG, resulting in definitive specifications in summer 2008. The evaluation of offers, including conceptual designs, took place in summer 2009. At present NRG is still active in the acquisition of the funding for the project. The licensing path has been started in autumn 2009 with a initiation note on the environmental impact assessment, EIA. The public hearings held in the lead to the advice from the national EIA committee for the approach of the assessment. The PALLAS project team in Petten will guide the design and build processes. It is also responsible for the licensing of the building and operation of PALLAS. The team also manages the design and construction for the infrastructure, such as cooling devices, including remnant heat utilization, and utility provisions. A particular responsibility for the team is the design and construction of experimental and isotope capsules, based on launch customer requirements. (author)

Microbiological safety of tenderized, proteinaceous, semi-processed and processed food prepared from poultry treated with ionizing radiation and other processes

International Nuclear Information System (INIS)

Klinger, I.; Lapidot, M.

1998-01-01

From a microbiological point of view, poultry meat is considered to be one of the most contaminated raw foods, harbouring bacteria, including pathogens such as Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Campylobacter spp. Some of these pathogens can survive the heat treatment used during the further processing of poultry meat into ready to eat products such as sausages and patties, and thus endanger consumer health, particularly in the young, the elderly and the immunocompromised. L. monocytogenes is of particular concern. This Gram positive, non-spore forming, psychrotrophic pathogen has been recognized as one of the causes of a severe food borne illness. The organism is relatively heat stable and can multiply under refrigeration conditions, but is sensitive to ionizing radiation. A survey conducted in Israel demonstrated that raw poultry meat was heavily contaminated with L. monocytogenes and that the pathogen could also be recovered from ready to eat poultry products. It was proposed that treatment of the raw meat with ionizing radiation prior to heating and use of the hazard analysis critical control point concept in the further processing plant would result in the elimination of contamination in ready to eat products.

Impact of Fragmentation Issue in Construction Industry: An Overview

Directory of Open Access Journals (Sweden)

Mohd Nawi Mohd Nasrun

2014-01-01

Full Text Available In general, fragmentation within the construction industry arises from two areas within the traditional construction process; the construction work process where the most significant division is in the separation of the design and construction phase, and the construction structure itself. The fragmentation process in traditional contracting practice further hinders the integration of construction knowledge among contractors, diminishing the opportunity for them to influence design decisions. When design professionals fail to consider as to how a contractor would construct the designed project results in scheduling problems, delays, and disputes during the construction process. Moving towards team integration is considered a significant strategy for overcoming the issue. Accordingly, this paper discusses the fragmentation issue in more detail including its definition, and causes and effects to the construction projects. It also explores that the team integration strategy alleviates scheduling problems, and helps avoid delays and disputes during the construction process, preventing harm to overall project performance.

Effect of heterogeneity and anisotropy related to the construction method on transfer processes in waste rock piles.

Lahmira, Belkacem; Lefebvre, René; Aubertin, Michel; Bussière, Bruno

Waste rock piles producing acid mine drainage (AMD) are partially saturated systems involving multiphase (gas and liquid) flow and coupled transfer processes. Their internal structure and heterogeneous properties are inherited from their wide-ranging material grain sizes, their modes of deposition, and the underlying topography. This paper aims at assessing the effect of physical heterogeneity and anisotropy of waste rock piles on the physical processes involved in the generation of AMD. Generic waste rock pile conditions were represented with the numerical simulator TOUGH AMD based on those found at the Doyon mine waste rock pile (Canada). Models included four randomly distributed material types (coarse, intermediate, fine and very fine-grained). The term "randomly" as used in this study means that the vertical profile and spatial distribution of materials in waste rock piles (internal structure) defy stratigraphy principles applicable to natural sediments (superposition and continuity). The materials have different permeability and capillary properties, covering the typical range of materials found in waste rock piles. Anisotropy with a larger horizontal than vertical permeability was used to represent the effect of pile construction by benches, while the construction by end-dumping was presumed to induce a higher vertical than horizontal permeability. Results show that infiltrated precipitation preferentially flows in fine-grained materials, which remain almost saturated, whereas gas flows preferentially through the most permeable coarse materials, which have higher volumetric gas saturation. Anisotropy, which depends on pile construction methods, often controls global gas flow paths. Construction by benches favours lateral air entry close to the pile slope, whereas end-dumping leads to air entry from the surface to the interior of the pile by secondary gas convection cells. These results can be useful to construct and rehabilitate waste rock piles to minimize

Utilisation of metallurgical by-products in road construction in the Czech Republic

Science.gov (United States)

Kresta, František

2017-09-01

Metallurgical by-products, primarily blast furnace slag and steel slag, have ranked among important alternative sources of fill as well as of material for the structural layers in highways. Main hazards of metallurgical by-products are closely connected to their chemical and mineralogical composition and they can be resulted in volume changes. Fears from possible deformations similar to the D47 motorway meant that metallurgical by-products were excluded from several public tenders of road construction. Comparison of blast furnace slag, steel slag and other metallurgical by products parameters allow us to define the most hazardous material as steelworks waste. Linear swelling of steelwork waste achieves more than 40% at 75°C and swelling pressure was higher than 1.5 MPa. Compositional heterogeneity of steelworks waste makes it difficult to establish the long-term behaviour of this material. At the present time we cannot ascertain which maximum values can be reached by deformation and what are the swelling pressures acting on the material while the volume changes are in progress.

AndrewN.BALDWIN; SimonA.AUSTIN; AndrewKEYS

2003-01-01

This paper describes a conceptual tool to enable construction professional to identify where waste is generated during the construction of buildings and address how it can be reduced. It allows an improvement in the waste management practices on site by forecasting future waste types and volumes. It will reduce waste volumes on site through identification of wasteful design practices. The tool contributes to all stages of design and construction. At the Concept Stage of Design the proposed methodology provides a framework for reducing waste through better informed decisions. At the Detailed Design Stage it gives a methodology to address the areas of concern and provide focused information to aid the reduction of waste through informed design decisions. During construction it provides a tool to predict waste types arising on site thus allowing a system of proaclive waste management that will aid skip segregation strategies leading to improved waste recycling and waste reuse.

Shi, Jing; Wang, Yangdong; Yang, Weimin; Tang, Yi; Xie, Zaiku

2015-12-21

The kaleidoscopic applications of zeolite catalysts (zeo-catalysts) in petrochemical processes has been considered as one of the major accomplishments in recent decades. About twenty types of zeolite have been industrially applied so far, and their versatile porous architectures have contributed their most essential features to affect the catalytic efficiency. This review depicts the evolution of pore models in zeolite catalysts accompanied by the increase in industrial and environmental demands. The indispensable roles of modulating pore models are outlined for zeo-catalysts for the enhancement of their catalytic performances in various industrial processes. The zeolites and related industrial processes discussed range from the uni-modal micropore system of zeolite Y (12-ring micropore, 12-R) in fluid catalytic cracking (FCC), zeolite ZSM-5 (10-R) in xylene isomerization and SAPO-34 (8-R) in olefin production to the multi-modal micropore system of MCM-22 (10-R and 12-R pocket) in aromatic alkylation and the hierarchical pores in FCC and catalytic cracking of C4 olefins. The rational construction of pore models, especially hierarchical features, is highlighted with a careful classification from an industrial perspective accompanied by a detailed analysis of the theoretical mechanisms.

Indigenous lunar construction materials

Science.gov (United States)

Rogers, Wayne P.; Sture, Stein

1991-01-01

The utilization of local resources for the construction and operation of a lunar base can significantly reduce the cost of transporting materials and supplies from Earth. The feasibility of processing lunar regolith to form construction materials and structural components is investigated. A preliminary review of potential processing methods such as sintering, hot-pressing, liquification, and cast basalt techniques, was completed. The processing method proposed is a variation on the cast basalt technique. It involves liquification of the regolith at 1200-1300 C, casting the liquid into a form, and controlled cooling. While the process temperature is higher than that for sintering or hot-pressing (1000-1100 C), this method is expected to yield a true engineering material with low variability in properties, high strength, and the potential to form large structural components. A scenario for this processing method was integrated with a design for a representative lunar base structure and potential construction techniques. The lunar shelter design is for a modular, segmented, pressurized, hemispherical dome which could serve as habitation and laboratory space. Based on this design, estimates of requirements for power, processing equipment, and construction equipment were made. This proposed combination of material processing method, structural design, and support requirements will help to establish the feasibility of lunar base construction using indigenous materials. Future work will refine the steps of the processing method. Specific areas where more information is needed are: furnace characteristics in vacuum; heat transfer during liquification; viscosity, pouring and forming behavior of molten regolith; design of high temperature forms; heat transfer during cooling; recrystallization of basalt; and refinement of estimates of elastic moduli, compressive and tensile strength, thermal expansion coefficient, thermal conductivity, and heat capacity.

Full Text Available In the Anyue Gasfield, Sichuan Basin, the Lower Cambrian Longwangmiao Fm gas reservoir in Moxi Block has enormous natural gas reserves, and it is a typical three-high (high temperature, high pressure, and high flow rate sour gas field. Its ground engineering project (with the designed gas processing capacity of 60 × 108 m3/a is characterized by high processing rate of each unit, complex process control, large construction load, restricted construction site and tight schedule. Based on the traditional engineering construction mode, however, it is difficult to complete the project design and construction within 16 months. In view of this, the design concept of unit large-scale modularization was introduced to implement “normalized design, scale purchase, factory-like prefabrication and modularized construction” and develop the modularization technology of large-scale surface engineering construction. This modularization technology is performed as follows. First, the modularized units are laid out reasonably according to the technological process. Second, the layout of modularized units is usually superimposed in the multi-layer framework. Third, those equipments with the same or similar operational modes, medium properties, functional characteristics and installation requirements are concentrated in the pattern of a module. Fourth, escape passageway is specially set up. Fifth, room for installation, maintenance and repair of large equipments is reserved. And sixth, transportation and hoisting requirements of modules are taken into consideration sufficiently. This technology is contributive to the improvement of design quality, effective shortening of design period, reduction of field working load, decrease of safety management risk of on-site installation, increase of production efficiency, conservation of land occupation and diminishment of construction investment. It plays a reference role in the modularized construction of surface
