    Full Text Available This paper studies the way a Local authority can provide a public service of its competence jointly or cooperatively with other public authorities. Specifically, article 12.4 of Directive 2014/24 /EU, on «contracts for the joint provision of public services», is analyzed. Its basis and the conditions that must be fulfilled for its valid use are studied, as it is an exception to the rules on public works contracts. The conclusion is that European law supports and regulates a traditional way of managing local public services.

    This study investigated the effect of knee joint angle and contraction intensity on the coactivation of the hamstring muscles (when acting as antagonists to the quadriceps) in young and older individuals of both sexes. A total of 25 young (24 ± 2.6 yr) and 26 older (70 ± 2.5 yr) healthy men and women participated. Maximal voluntary isometric contraction of the knee extensors and flexors was assessed at two knee joint angles (90° and 60°, 0° = full extension). At each angle, participants performed submaximal contractions of the knee extensors (20%, 50%, and 80% maximal voluntary isometric contraction), whereas surface EMG was simultaneously acquired from the vastus lateralis and biceps femoris muscles to assess the level (EMG root-mean-square) of agonist activation and antagonist coactivation. Subcutaneous adipose tissue in the areas corresponding to surface EMG electrode placements was measured via ultrasonography. The contractions performed at 90° knee flexion demonstrated higher levels of antagonist coactivation (all P < 0.01) and agonist activation (all P < 0.01) as a function of contraction intensity compared with the 60° knee flexion. Furthermore, after controlling for subcutaneous adipose tissue, older participants exhibited a higher level of antagonist coactivation at 60° knee flexion compared with young participants (P < 0.05). The results of the present study suggest that 1) the antagonist coactivation is dependent on knee joint angle and contraction intensity and 2) subcutaneous adipose tissue may affect the measured coactivation level likely because of a cross-talk effect. Antagonist coactivation may play a protective role in stabilizing the knee joint and maintaining constant motor output.

    The purpose of this study was to compare the relationship between surface electromyography (EMG) and knee joint angle of the vastus intermedius muscle (VI) with the synergistic muscles in the quadriceps femoris (QF) muscle group. Fourteen healthy men performed maximal voluntary contractions during isometric knee extension at four knee joint angles from 90°, 115°, 140°, and 165° (180° being full extension). During the contractions, surface EMG was recorded at four muscle components of the QF muscle group: the VI, vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) muscles. The root mean square of the surface EMG at each knee joint angle was calculated and normalized by that at a knee joint angle of 90° for individual muscles. The normalized RMS of the VI muscle was significantly lower than those of the VL and RF muscles at the knee joint angles of 115° and 165° and those of the VL, VM, and RF muscles at the knee joint angle of 140° (Pneuromuscular activation of the VI muscle is regulated in a manner different from the alteration of the knee joint angle compared with other muscle components of the QF muscle group. © 2011 John Wiley & Sons A/S.

  10. Skeletal muscle contraction in protecting joints and bones by absorbing mechanical impacts

    2016-09-01

    We have previously hypothesized that the dissipation of mechanical energy of external impact is a fundamental function of skeletal muscle in addition to its primary function to convert chemical energy into mechanical energy. In this paper, a mathematical justification of this hypothesis is presented. First, a simple mechanical model, in which the muscle is considered as a simple Hookean spring, is considered. This analysis serves as an introduction to the consideration of a biomechanical model taking into account the molecular mechanism of muscle contraction, kinetics of myosin bridges, sarcomere dynamics, and tension of muscle fibers. It is shown that a muscle behaves like a nonlinear and adaptive spring tempering the force of impact and increasing the duration of the collision. The temporal profiles of muscle reaction to the impact as functions of the levels of muscle contraction, durations of the impact front, and the time constants of myosin bridges closing, are obtained. The absorption of mechanical shock energy is achieved due to the increased viscoelasticity of the contracting skeletal muscle. Controlling the contraction level allows for the optimization of the stiffness and viscosity of the muscle necessary for the protection of the joints and bones.

    Individuals with knee OA often exhibit greater co-contraction of antagonistic muscle groups surrounding the affected joint which may lead to increases in dynamic joint stiffness. These detrimental changes in the symptomatic limb may also exist in the contralateral limb, thus contributing to its risk of developing knee osteoarthritis. The purpose of this study is to investigate the interlimb symmetry of dynamic knee joint stiffness and muscular co-contraction in knee osteoarthritis. Muscular co-contraction and dynamic knee joint stiffness were assessed in 17 subjects with mild to moderate unilateral medial compartment knee osteoarthritis and 17 healthy control subjects while walking at a controlled speed (1.0m/s). Paired and independent t-tests determined whether significant differences exist between groups (pknees compared to the healthy group (p=0.051). Subjects with mild to moderate knee osteoarthritis maintain symmetric control strategies during gait. Copyright © 2014 Elsevier Ltd. All rights reserved.

  12. Muscle co-contraction modulates damping and joint stability in a three-link bio mechanical limb

    Full Text Available Computational models of neuromotor control require forward models of limb movement that can replicate the natural relationships between muscle activation and joint dynamics without the burdens of excessive anatomical detail. We present a model of a three-link biomechanical limb that emphasizes the dynamics of limb movement within a simplified two-dimensional framework. Muscle co-contraction effects were incorporated into the model by flanking each joint with a pair of antagonist muscles that may be activated independently. Muscle co-contraction is known to alter the damping and stiffness of limb joints without altering net joint torque. Idealized muscle actuators were implemented using the Voigt muscle model which incorporates the parallel elasticity of muscle and tendon but omits series elasticity. The natural force-length-velocity relationships of contractile muscle tissue were incorporated into the actuators using ideal mathematical forms. Numerical stability analysis confirmed that co-contraction of these simplified actuators increased damping in the biomechanical limb consistent with observations of human motor control. Dynamic changes in joint stiffness were excluded by the omission of series elasticity. The analysis also revealed the unexpected finding that distinct stable (bistable equilibrium positions can co-exist under identical levels of muscle co-contraction. We map the conditions under which bistability arises and prove analytically that monostability (equifinality is guaranteed when the antagonist muscles are identical. Lastly we verify these analytic findings in the full biomechanical limb model.

  13. Medial Elbow Joint Space Increases With Valgus Stress and Decreases When Cued to Perform A Maximal Grip Contraction.

    Previous research indicates that the amount of valgus torque placed on the elbow joint during overhead throwing is higher than the medial ulnar collateral ligament (UCL) can tolerate. Wrist and finger flexor muscle activity is hypothesized to make up for this difference, and in vitro studies that simulated activity of upper extremity musculature, specifically the flexor digitorum superficialis and flexor carpi ulnaris, support this hypothesis. To assess the medial elbow joint space at rest, under valgus stress, and under valgus stress with finger and forearm flexor contraction by use of ultrasonography in vivo. Controlled laboratory study. Participants were 22 healthy males with no history of elbow dislocation or UCL injury (age, 21.25 ± 1.58 years; height, 1.80 ± 0.08 m; weight, 79.43 ± 18.50 kg). Medial elbow joint space was measured by use of ultrasonography during 3 separate conditions: at rest (unloaded), under valgus load (loaded), and with a maximal grip contraction under a valgus load (loaded-contracted) in both limbs. Participants lay supine with their arm abducted 90° and elbow flexed 30° with the forearm in full supination. A handgrip dynamometer was placed in the participants' hand to grip against during the contracted condition. Images were reduced in ImageJ to assess medial elbow joint space. A 2-way (condition × limb) repeated-measures analysis of variance and Cohen's d effect sizes were used to assess changes in medial elbow joint space. Post hoc testing was performed with a Bonferroni adjustment to assess changes within limb and condition. The medial elbow joint space was significantly larger in the loaded condition (4.91 ± 1.16 mm) compared with the unloaded condition (4.26 ± 1.23 mm, P space increases under a valgus load and then decreases when a maximal grip contraction is performed. This indicates that wrist and finger flexor muscle contraction may assist in limiting medial elbow joint space, a result similar to findings of previous

    Relating the electromyogram (EMG) to joint torque is useful in various application areas, including prosthesis control, ergonomics and clinical biomechanics. Limited study has related EMG to torque across varied joint angles, particularly when subjects performed force-varying contractions or when optimized modeling methods were utilized. We related the biceps-triceps surface EMG of 22 subjects to elbow torque at six joint angles (spanning 60° to 135°) during constant-posture, torque-varying contractions. Three nonlinear EMG σ -torque models, advanced EMG amplitude (EMG σ ) estimation processors (i.e., whitened, multiple-channel) and the duration of data used to train models were investigated. When EMG-torque models were formed separately for each of the six distinct joint angles, a minimum "gold standard" error of 4.01±1.2% MVC(F90) resulted (i.e., error relative to maximum voluntary contraction at 90° flexion). This model structure, however, did not directly facilitate interpolation across angles. The best model which did so achieved a statistically equivalent error of 4.06±1.2% MVC(F90). Results demonstrated that advanced EMG σ processors lead to improved joint torque estimation as do longer model training durations.

  17. Effect of boot shaft stiffness on stability joint energy and muscular co-contraction during walking on uneven surface.

    Increased boot shaft stiffness may have a noticeable impact on the range of motion of the ankle joint. Therefore, the ability of the ankle joint to generate power for propulsion might be impaired. This might result in compensatory changes at the knee and hip joint. Besides, adaptability of the subtalar joint to uneven surface might be reduced, which could in turn affect stability. The aim of the study was therefore to investigate the influence of boot shaft stiffness on biomechanical gait parameters. Fifteen healthy young adults walked over coarse gravel wearing two different hiking boots that differed by 50% in passive shaft stiffness. Leg kinematics, kinetics and electromyography were measured. Gait velocity and indicators for stability were not different when walking with the hard and soft boot shaft over the gravel surface. However, the hard boot shaft decreased the ankle range of motion as well as the eccentric energy absorbed at the ankle joint. As a consequence, compensatory changes at the knee joint were observed. Co-contraction was increased, and greater eccentric energy was absorbed. Therefore, the efficiency of gait with hard boots might be decreased and joint loading at the knee might be increased, which might cause early fatigue of knee muscles during walking or hiking. The results of this study suggest that stiffness and blocking of joint motion at the ankle should not be equated with safety. A trade-off between lateral stiffness and free natural motion of the ankle joint complex might be preferable.

    Agonist and antagonist muscle co-contractions during motor tasks are greater in the elderly than in young adults. During normal walking, muscle co-contraction increases with gait speed in young adults, but not in elderly adults. However, no study has compared the effects of speed on muscle co-contraction of the ankle joint during dynamic postural control in young and elderly adults. We compared muscle co-contractions of the ankle joint between young and elderly subjects during a functional stability boundary test at different speeds. Fifteen young adults and 16 community-dwelling elderly adults participated in this study. The task was functional stability boundary tests at different speeds (preferred and fast). Electromyographic evaluations of the tibialis anterior and soleus were recorded. The muscle co-contraction was evaluated using the co-contraction index (CI). There were no statistically significant differences in the postural sway parameters between the two age groups. Elderly subjects showed larger CI in both speed conditions than did the young subjects. CI was higher in the fast speed condition than in the preferred speed condition in the young subjects, but there was no difference in the elderly subjects. Moreover, after dividing the analytical range into phases (acceleration and deceleration phases), the CI was larger in the deceleration phase than in the acceleration phase in both groups, except for the young subjects in the fast speed conditions. Our results showed a greater muscle co-contraction of the ankle joint during dynamic postural control in elderly subjects than in young subjects not only in the preferred speed condition but also in the fast speed condition. In addition, the young subjects showed increased muscle co-contraction in the fast speed condition compared with that in the preferred speed condition; however, the elderly subjects showed no significant difference in muscle co-contraction between the two speed conditions.

    Minimally invasive total hip arthroplasty (THA) is presumed to provide functional and clinical benefits, whereas in fact the literature reveals that gait and posturographic parameters following THA do not recover values found in the general population. There is a significant disturbance of postural sway in THA patients, regardless of the surgical approach, although with some differences between approaches compared to controls: the anterior and anterolateral minimally invasive approaches seem to be more disruptive of postural parameters than the posterior approach. Electromyographic (EMG) study of the hip muscles involved in surgery [gluteus maximus (GMax), gluteus medius (GMed), tensor fasciae latae (TFL), and sartorius (S)] could shed light, the relevant literature involves discordant methodologies. We developed a methodology to assess EMG activity during maximal voluntary contraction (MVC) of the GMax, GMed, TFL and sartorius muscles as a reference for normalization. A prospective study aimed to assess whether hip joint positioning and the learning curve on an MVC test affect the EMG signal during a maximal voluntary contraction. Hip positioning and the learning curve on an MVC test affect EMG signal during MVC of GMax, GMed, TFL and S. Thirty young asymptomatic subjects participated in the study. Each performed 8 hip muscle MVCs in various joint positions recorded with surface EMG sensors. Each MVC was performed 3 times in 1 week, with the same schedule every day, controlling for activity levels in the preceding 24h. EMG activity during MVC was expressed as a ratio of EMG activity during unipedal stance. Non-parametric tests were applied. Statistical analysis showed no difference according to hip position for abductors or flexors in assessing EMG signal during MVC over the 3 sessions. Hip abductors showed no difference between abduction in lateral decubitus with hip straight versus hip flexed: GMax (19.8±13.7 vs. 14.5±7.8, P=0.78), GMed (13.4±9.0 vs. 9.9±6

    In this study, we sought to determine the cellular source of inducible nitric oxide synthase (iNOS) induced in lymphatic endothelial cells (LECs) in response to tumor necrosis factor (TNF), the effects of iNOS on lymphatic smooth muscle cell (LSMC) function and on the development of arthritis in TNF-transgenic (TNF-Tg) mice, and whether iNOS inhibitors improve lymphatic function and reduce joint destruction in inflammatory erosive arthritis. We used quantitative polymerase chain reactions, immunohistochemistry, histology, and near-infrared imaging to examine (1) iNOS expression in podoplanin + LECs and lymphatic vessels from wild-type (WT) and TNF-Tg mice, (2) iNOS induction by TNF in WT LECs, (3) the effects of iNOS inhibitors on expression of functional muscle genes in LSMCs, and (4) the effects of iNOS inhibitors on lymphatic vessel contraction and drainage, as well as the severity of arthritis, in TNF-Tg mice. LECs from TNF-Tg mice had eight fold higher iNOS messenger RNA levels than WT cells, and iNOS expression was confirmed immunohistochemically in podoplanin + LECs in lymphatic vessels from inflamed joints. TNF (0.1 ng/ml) increased iNOS levels 40-fold in LECs. LSMCs cocultured with LECs pretreated with TNF had reduced expression of functional muscle genes. This reduction was prevented by ferulic acid, which blocked nitric oxide production. Local injection of L-N(6)-(1-iminoethyl)lysine 5-tetrazole-amide into inflamed paws of TNF-Tg mice resulted in recovery of lymphatic vessel contractions and drainage. Treatment of TNF-Tg mice with ferulic acid reduced synovial inflammation as well as cartilage and bone erosion, and it also restored lymphatic contraction and drainage. iNOS is produced primarily by LECs in lymphatic vessel efferent from inflamed joints of TNF-Tg mice in response to TNF and inhibits LSMC contraction and lymph drainage. Ferulic acid represents a potential new therapy to restore lymphatic function and thus improve inflammatory

    Oil companies make a business by bearing the risks of investing in, and making profits from, oil and gas operations. International Oil Companies (IOC) are the recognised leaders in technology and develop expertise in the management of technical such as subsurface and surface uncertainties through seismic surveys, well drilling and production facilities. In export oriented oil and gas developments, IOCs also carry the commercial risks associated with the export market (ups and downs in the demand for oil and gas) that could make the project non-profitable, if not properly managed.Conversely, Local Oil Companies (LOCs), i.e. indigenous private or state owned companies, are more adapt at developing expertise in the management of the local environmental, domestic market and political risks associated with the area or country of operations. It is recognised that in certain countries some LOCs are also making significant progress in the acquisition of modern technology. Any critical business risks which cannot be adequately managed by either the IOC or the LOC will require the involvement of third party, who will normally provide guarantee or securitisation in one form or another.A partnership between local and international oil companies has become accepted to be the most secure and profitable arrangement in international oil and gas business. In the Niger Delta, which is mature oil and gas province and as such non-market related risks, particularly technical and supply risks, are substantially reduced, Joint Venture type of arrangement is considered the most suitable form of partnership. Joint Venture arrangement allows each partner to fund the venture in direct proportion to its participation interest. Because of the reduced risks profile, the joint venture is more bankable; each partner can therefore secure funding for its share with its revenue profile. In Nigeria, however, where the revenue profile (and consequently development budget) of the dominant local player

Development of the competition in economy is a multidimensional task which decision substantially depends on efficiency of carrying out a state policy in a wide range of the directions: from macroeconomic policy, creation of favorable investment climate, including development of financial and tax system, decrease in administrative and infrastructure barriers, before protection of the rights of citizens and national policy. Due to the complexity of a task dynamic landmark approach to work on development of a competition policy in connection with development of contract forms of joint activity of small and large business in the Russian Federation and to formation of the respective directions is necessary. For research by authors of research the following methods are chosen: a statistical method, a reference method to value, a comparative method, system approach, a historical method and a method of the economic analysis of the public relations and the right. Research covers the latest sources in the field reflecting the last economic and standard and legal changes, in particular, them treat: the statistical given, expert estimates, regulations, acts of judicial and administrative practice, scientific publications of economists

    The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management, referred to as the 'Joint Convention', is the result of international discussions that followed the adoption of the Convention on Nuclear Safety, in 1994. France signed the Joint Convention at the General Conference of the International Atomic Energy Agency (IAEA) held on 29 September 1997, the very first day the Joint Convention was opened for signature. She approved it on 22 February 2000 and filed the corresponding instruments with the IAEA on 27 April 2000. The Joint Convention entered into force on 18 June 2001. For many years, France has been taking an active part in the pursuit of international actions to reinforce nuclear safety and considers the Joint Convention to be a key step in that direction. The fields covered by the Joint Convention have long been part of the French approach to nuclear safety. For his second report, France presented a document reflecting the viewpoints of the various stakeholders (regulatory authorities and operators). Thus, for each of the chapters in which the regulatory authority is not the only party to express its point of view, a three-stage structure was adopted: first of all a description by the regulatory authority of the regulations, followed by a presentation by the operators of the steps taken to meet the regulations and finally, an analysis by the regulatory authority of the steps taken by the operators. France received questions and comments from the other contracting parties of the joint convention and answered them in the present document

  11. Polymorphic Contracts

    Science.gov (United States)

    Belo, João Filipe; Greenberg, Michael; Igarashi, Atsushi; Pierce, Benjamin C.

    Manifest contracts track precise properties by refining types with predicates - e.g., {x : Int |x > 0 } denotes the positive integers. Contracts and polymorphism make a natural combination: programmers can give strong contracts to abstract types, precisely stating pre- and post-conditions while hiding implementation details - for example, an abstract type of stacks might specify that the pop operation has input type {x :α Stack |not ( empty x )} . We formalize this combination by defining FH, a polymorphic calculus with manifest contracts, and establishing fundamental properties including type soundness and relational parametricity. Our development relies on a significant technical improvement over earlier presentations of contracts: instead of introducing a denotational model to break a problematic circularity between typing, subtyping, and evaluation, we develop the metatheory of contracts in a completely syntactic fashion, omitting subtyping from the core system and recovering it post facto as a derived property.

    Full Text Available Administrative contracts are a special type of contract where usually one of the contracting parties is a public law body and which is concluded for the performance of public service and the realization of a public interest. They go a long way since its inception to its eventual final acceptance of all the legal systems. One of the enduring characteristics of this type of contract is their disquised or unnoticed existence. This is why only monitoring their development may lead to a complete understanding of the importance and essence of this institution as well as the need for its complete legal regulation.

  15. Team incentives in relational contracts

    2003-01-01

    Incentive schemes for teams are compared. I ask: under which conditions are relational incentive contracts based on joint performance evaluation, relative performance evaluation and independent performance evaluation self-enforceable. The framework of Che and Yoo (2001) on team incentives is combined with the framework of Baker, Gibbons and Murphy (2002) on relational contracts. In a repeated game between one principal and two agents, I find that incentives based on relative or independent performance are expected to dominate when the productivity of effort is high, while joint performance evaluation dominates when productivity is low. Incentives based on independent performance are more probable if the agents own critical assets. (author)

    To make energy available economically and in sufficient quantity is a main point for the future of an industrial and more for a developing country. The investment costs and the availability of a power plant and in particular for a nuclear power plant are the most significant factors in the economic operation of the plant. In the phase before signing the contract the essential decisions are made with high influence in the economic operation and the availability of the plant. A turn-key contract offers good possibilities to minimize the risks referring a) the plant quality and functionality, b) the plant investment cost, c) the plant completion date, d) the handling of the licensing procedures, e) the availability of the operation. The lecture mentions the points which are of high influence for a successful erection and operation period and which must be clarified before signing the contract between the buyer and supplier of the plant.

    Science.gov (United States)

    Sweeney, H Lee; Hammers, David W

    2018-02-01

    SUMMARYMuscle cells are designed to generate force and movement. There are three types of mammalian muscles-skeletal, cardiac, and smooth. Skeletal muscles are attached to bones and move them relative to each other. Cardiac muscle comprises the heart, which pumps blood through the vasculature. Skeletal and cardiac muscles are known as striated muscles, because the filaments of actin and myosin that power their contraction are organized into repeating arrays, called sarcomeres, that have a striated microscopic appearance. Smooth muscle does not contain sarcomeres but uses the contraction of filaments of actin and myosin to constrict blood vessels and move the contents of hollow organs in the body. Here, we review the principal molecular organization of the three types of muscle and their contractile regulation through signaling mechanisms and discuss their major structural and functional similarities that hint at the possible evolutionary relationships between the cell types.

    2006-01-01

    The current state of the electric power industry in Ontario was discussed with particular reference to the procurement of contracts and why the Ontario Power Authority (OPA) must be contracting to resolve many of Ontario's electricity issues. As Ontario increasingly relies on imports and natural gas-fired generation, the price of electricity continues to rise given that supply is at a low level. In addition to the generation gap, there are also several transmission constrained areas in Ontario, particularly in the Greater Toronto Area (GTA). The OPA announced 2 projects totalling 1900 MW to relieve congestion. According to the Independent Electricity System Operator (IESO), the total potential opportunity for new generation by 2015 is about 5,000 to 7,000 megawatts. OPA is expected to launch procurement processes for up to 1000 MW of cogeneration, 250 MW of province-wide conservation initiatives, 1900 MW of generation in the western part of the GTA, and 600 MW of generation in downtown Toronto. New nuclear capacity is also anticipated in addition to renewables and conservation/demand management (CDM) initiatives. The OPA's competitive procurement processes will include requests for expressions of interest, requests for qualifications and requests for proposals. The challenge of balancing the technical complexities and realities of procuring generation assets with the need for a fair procurement process was discussed. Contracts will be designed to react to market signals and will include 3 styles: tariff style, tolling style and standard offer contract. OPA will make every effort to balance generator and ratepayer interests. 6 figs

    Full Text Available In calculi for modelling communication protocols, internal and external choices play dual roles. Two external choices can be viewed naturally as dual too, as they represent an agreement between the communicating parties. If the interaction fails, the past agreements are good candidates as points where to roll back, in order to take a different agreement. We propose a variant of contracts with synchronous rollbacks to agreement points in case of deadlock. The new calculus is equipped with a compliance relation which is shown to be decidable.

There are Accounting Act No. 563/1991 of Coll. and Regulation No. 500/2002 of Coll., Czech Accounting Standards in the Czech Republic. Both systems are based on different principles so there are many differences. The Czech Accounting System (CAS is based on the rules while IAS/IFRS are based on principles (Kovanicová, 2005. These differences are mainly caused by the different philosophy. CAS prefers the fiscal policy to the economic substance while IAS/IFRS prefere the economic substance. One of the most significant dif­fe­ren­ces is in the field of revenue recording. There are two standards concerning the revenues recording (IAS 18 − Revenue, IAS 11 – Construction Contracts in IAS/IFRS.

Forty-two volunteers with 84 clinically normal TMJs were imaged in the sagittal and coronal planes with surface coil MR imaging. Sagittal closed and open and coronal closed views were obtained bilaterally in all volunteers. The images were classified as normal (superior disk position) or abnormal (disk displacement of degenerative joint disease). Eighteen joints in 11 volunteers were abnormal; 12 had disk displacement with reduction and six had disk displacement without reduction, with associated degenerative joint disease in three of the six. Asymptomatic internal derangement and degenerative joint disease occur in about one-fourth of asymptomatic volunteers

    Ulysses contracts have faced paternalism objections since they first were proposed. Since the contracts are designed to override a present request from a legally competent patient in favor of a past request made by that patient, enforcement of these contracts was argued to be unjustifiable strong paternalism. Recent legal developments and new theories of practical reasoning suggest that the discussion of Ulysses contracts should be revived. This paper argues that with a proper understanding of the future-directed planning embodied in Ulysses contracts, the charge of strong paternalism can be answered, and the enforcement of some Ulysses contracts may be justified under the rubric of weak paternalism.

    The authors discuss how x-ray examination is essential in the diagnosis and evaluation of the arthritides. Most arthritides are first suspected by the clinician, and x-ray evaluation of these entities along with laboratory testing is important for confirmation of the clinical diagnosis and in staging of the disease process. Several arthritides are often diagnosed first by the podiatrist on x-ray evaluation, including pseudogout, ankylosing spondylitis, early rheumatoid arthritis, degenerative joint disease, and tuberculosis of bone. The joint responds to insult in only a limited number of ways that become apparent on x-ray. The soft tissues surrounding the joint, the articulating bones, and alignment of the joint space may all be involved by the arthritic process. On roentgenographic examination, the soft tissues must be examined for edema, masses, calcifications, and atrophy. The articulating bones must be examined for demineralization, erosions, osteophytes, periosteal reaction, cysts and sclerosis

    We use 2003 and 2004 ARMS data to analyze variations in contract duration among growers of broilers who hold production contracts. Most contracts cover just a single flock, but many extend for 1-2 years, and a significant minority of broiler contracts specify lengths of 5, 10, and even 15 years. We find that grower debt and production volume are inversely related to the choice of a short term (a year or less) contract, while lengthy prior experience with the contractor promotes short term con...

  18. Joint Intentionality

    Directory of Open Access Journals (Sweden)

    Koreň Ladislav

    2016-03-01

    Full Text Available According to the shared intentionality hypothesis proposed by Michael Tomasello, two cognitive upgrades – joint and collective intentionality, respectively – make human thinking unique. Joint intentionality, in particular, is a mindset supposed to account for our early, species-specific capacity to participate in collaborative activities involving two (or a few agents. In order to elucidate such activities and their proximate cognitive-motivational mechanism, Tomasello draws on philosophical accounts of shared intentionality. I argue that his deference to such cognitively demanding accounts of shared intentional activities is problematic if his theoretical ambition is in part to show that and how early (prelinguistic and precultural capacities for joint action contribute to the development of higher cognitive capacities.

  19. Population-based contracting (population health): part II.

    Science.gov (United States)

    Jacofsky, D J

    2017-11-01

    Modern healthcare contracting is shifting the responsibility for improving quality, enhancing community health and controlling the total cost of care for patient populations from payers to providers. Population-based contracting involves capitated risk taken across an entire population, such that any included services within the contract are paid for by the risk-bearing entity throughout the term of the agreement. Under such contracts, a risk-bearing entity, which may be a provider group, a hospital or another payer, administers the contract and assumes risk for contractually defined services. These contracts can be structured in various ways, from professional fee capitation to full global per member per month diagnosis-based risk. The entity contracting with the payer must have downstream network contracts to provide the care and facilities that it has agreed to provide. Population health is a very powerful model to reduce waste and costs. It requires a deep understanding of the nuances of such contracting and the appropriate infrastructure to manage both networks and risk.

  20. Optimal Lease Contract for Remanufactured Equipment

    Iskandar, B. P.; Wangsaputra, R.; Pasaribu, U. S.; Husniah, H.

    2018-03-01

    In the last two decades, the business of lease products (or equipment) has grown significantly, and many companies acquire equipment through leasing. In this paper, we propose a new lease contract under which a product (or equipment) is leased for a period of time with maximum usage per period (e.g. 1 year). This lease contract has only a time limit but no usage limit. If the total usage per period exceeds the maximum usage allowed in the contract, then the customer (as a lessee) will be charged an additional cost. In general, the lessor (OEM) provides a full coverage of maintenance, which includes PM and CM under the lease contract. It is considered that the lessor offers the lease contract for a remanufactured product. We presume that the price of the lease contract for the remanufactured product is much lower than that of a new one, and hence it would be a more attractive option to the customer. The decision problem for the lessee is to select the best option offered that fits to its requirement, and the decision problem for the lessor is find the optimal maintenance efforts for a given price of the lease option offered. We first find the optimal decisions independently for each party, and then the joint optimal decisions for both parties.

  1. Joint imaging

    International Nuclear Information System (INIS)

    Hengst, W.

    1984-01-01

    Joint imaging is a proven diagnostic procedure which has become indispensable to the detection and treatment of different joint diseases in almost all disciplines. The method is suited for early diagnosis of joint affections both in soft tissue and bone which cannot be detected by X-ray or other procedures. The local activity accumulation depends on the rate of metabolism and is visualized in the scan, which in turn enables the extension and floridity of focal lesions to be evaluated and followed-up. Although joint scans may often give hints to probabilities relevant to differential diagnosis, the method is non-specific and only useful if based on the underlying clinical picture and X-ray finding, if possible. The radiation exposure is very low and does not represent a hazard in cases of adequate assessment of indication. In pregnant women and children the assessment of indication has to be based on very strict principles. The method is suited for out-patient diagnosis and can be applied in all installations equipped with a gamma camera and a technetium generator. (orig.) [de

    Watson, T

    1999-01-01

    Since July 1994, the CERN Civil Engineering group within the ST division has been preparing and engaging contracts related to the Large Hadron Collider (LHC) project. Several of these contracts have values in excess of 10 MCHF and will be executed over a number of years; as such they represent an important part of the infrastructure works required for the LHC. To date, in excess of two hundred and fifty companies have been consulted in relation to these contracts. Contracts or orders have been placed with over thirty companies or joint ventures of companies from nearly all the CERN Member States. This paper aims to show the inter-relationships between these contracts and how the Civil Engineering group is carrying out the management of these important LHC contracts. The organization of the group will be explained along with the roles of individual members within the group.

    Following discussion at TREF and on the recommendation of the Finance Committee, Council approved a new staff contract policy, which became effective on 1 January 2006. Its application is covered by a new Administrative Circular No. 2 (Rev. 3) 'Recruitment, appointment and possible developments regarding the contractual position of staff members'. The revised circular replaces the previous Circulars No. 9 (Rev. 3) 'Staff contracts' and No. 2 (Rev. 2) 'Guidelines and procedures concerning recruitment and probation period for staff members'. The main features of the new contract policy are as follows: The new policy provides chances for long-term employment for all staff recruits staying for four years without distinguishing between those assigned to long-term or short-term activities when joining CERN. In addition, it presents a number of simplifications for the award of ICs. There are henceforth only 2 types of contract: Limited Duration (LD) contracts for all recruitment and Indefinite Contracts (IC) for...

    2008-01-01

    Shortages of rigs and personnel have encouraged discussion of designing incentive contracts in the drilling sector. However, for the drilling contracts, there are not a large variety of contract types in use. This article describes and analyses incentives for drilling contractors. These are directly represented by the compensation formats utilised in the present and in the consecutive drilling contracts. Indirectly, incentives are also provided by the evaluation criteria that oil companies use for awarding drilling assignments. Changes in contract format pose a number of relevant questions relating to resource management, and the article takes an in-depth look at some of these. Do evaluation criteria for awarding drilling assignments encourage the development of new technology and solutions? How will a stronger focus on drilling efficiency influence reservoir utilisation?

    Some selected issues which are facing both operators and contractors in drilling for oil and gas, such as the allocation of risk by contract and by statute and the implementation of new technologies, were discussed. There are three varieties of written drilling contracts used in Canada: (1) day work and meterage contracts, (2) master drilling agreements, and (3) contracts that are used in construction projects that do not specifically relate to drilling. Issues relevant to the contractual allocation of risk, to implementing new drilling technologies, to reconciling contract and statute liability, and the formation of strategic alliances for mutual benefit, and the factors contributing to the success of such alliances were explored. 12 refs

  17. THE PSYCHOLOGICAL CONTRACT

    Directory of Open Access Journals (Sweden)

    Blanca Giorgiana GRAMA

    2015-04-01

    Full Text Available The psychological contract became known as a research paradigm within corporate research, providing a broad framework which explains the employee-company relations. Despite all this, there are still many debates on the concept and a series of criticism were expressed that led to the necessity of some more rigorous theoretical and empirical analysis. The psychological contract refers to the unwritten, implicit expectations that employees have from the company and vice versa; it is that which defines the things the employee expects from the employer. Consequently, each of the parties involved in the contract may have different perceptions on these commitments and obligations. Thus the psychological contract may be regarded as an exchange relation between the employer and the employee. Breaking the psychological contract affects the performance, the morale, and the motivation of the staff in a negative manner. The information presented in this paper is intended to contribute to the theoretical and methodological development of the concept.

    Full Text Available A chattel mortgage contract is the expression of a real guarantee that gives the creditor precedence over other creditors, in addition to the general pledge upon the belongings of the debtor. It refers to the sale of mortgaged movable assets, exclusively or prioritized in favor of the mortgaging creditor, in case the debtor does not comply with his / her commitments, under the signed mortgage contract. Beginning from this purpose, shared by both sides (as the chattel mortgage contract is synallagmatic, in case the debtor is unable to fulfill his / her commitments, the sides reach a situation of enforcement of the signed chattel mortgage contract. Given the legal status of the chattel mortgage contract [Art. 2387-2477 Noul Cod Civil , Universul Juridic, Bucureşti, 2016, ISBN 978-606-673-792-0], the principle of binding force of the contract and the principle according to which signed legal conventions will entail legal effects, the Romanian law maker developed the proper legal framework for the enforcement of the chattel mortgage contract.

  1. JURIDICAL WILL IN CONTRACTS

    Directory of Open Access Journals (Sweden)

    Emilian CIONGARU

    2015-07-01

    Full Text Available In the business law, almost all judicial relationships of private law are obligational juridical relationships which are made up of legal acts and facts. The most important legal act is the contract since it is the basis of the social life in any community meaning that it represents the most important economic and juridical instrument for the participants to a contract. The persons are free and equal in society and, consequently, no power is valid and fundamental unless it relies on their consent, namely on a contract. So, the existence of a civil contract relies on the principles of consensualism, a perception based on moral rules to observe one’s promises, to have good faith and to observe the interests of your fellow creature. The exterior manifestation, the expression or declaration of the juridical will constitutes the consent of such person in making the structure of contract. The declared will must correspond to the person’s real will and the adoption and declaration of the juridical will must take place consciously. Any contract that does not derive from juridical will is null and the civilizing character is inexistent. The principles giving sense to consensualism is the one of agreement between parties so as to produce legal effects by itself and it is enough for the conclusion of a contract, regardless of the form in which it is exteriorized, a principle expressed by the Latin adagio pacta sunt servanda.

    The report surveys the central points in the literature about contracts on geographical price differences and transmission rights in the power market. It is commonly believed that such contracts may reduce market power and contribute to better network investments. The theoretical debate is in part unfinished and largely based on very stylised assumptions. There is some indication that such contracts may not be very useful in practice. But they may be useful in some cases, perhaps in particular when power is transported outside limited surplus areas and for certain investment decisions where there is no systems operator with a natural responsibility

    Spending on clinical contracts continues to outpace spending on business services, but may be leveling off. The 12th annual Contract Management Survey shows that the performance of clinical vendors is now comparable to business service vendors in meeting savings targets. Both business and clinical vendors are receiving higher marks from hospital leaders, but execs quickly respond to low marks by bringing the service back in-house of changing vendors.

    For the second year running, hospitals are spending more on clinical outsourcing than on business services. The Eleventh Annual Contract Services Survey shows that, in clinical areas, executives use outsourcing to acquire specialized expertise with cost savings secondary. Reducing costs and FTEs are the primary reasons for outsourcing business operations. Business service contracts are more likely to meet expectations for cost savings. Overall, satisfaction levels are up, but in some areas there's still a lot of room for improvement. This report examines current trends in outsourcing, strategies for the future, satisfaction levels, the decisionmaking process, contract features, and costs.

    The contract is the last and final step of project planning and the first step of project implementation. The contract has to specify in detail and to the point, as concisely as possible, the complete scope of supplies and work, define all technical particulars and requirements, put forward the conditions of legal, regulatory, administrative and financial procedure, prepare for operating and maintenance instructions to be issued after commissioning. In short, the contract is expected to be a reliable instrument during the manufacturing and construction period as well as a guide-book to assist the owner afterwards in the operation and maintenance of the plant.

    Because corruption must be hidden from the public and is not enforced by courts it entails transaction costs, which are larger than those from legal exchange. This suggests that corrupt contracts are primarily relational contracts where legal exchange serves as a basis for sealing and enforcing corrupt agreements.

  15. An unsatisfactory contract policy

    CERN Multimedia

    Association du personnel

    2012-01-01

    For the last 15 years contract policy has been one of the top priorities of CERN staff, as expressed in successive surveys initiated by the Staff Association. In one’s professional life, having some forward vision of one’s career prospects is the key to loyalty and motivation. On the contrary, instability about the future is always at the root of anxiety, conflicts, or even health problems. A good employer must therefore balance the needs of the Company and those of its employees. CERN’s current contract policy, as described in the Administrative Circular No 2, states that staff members should first obtain a limited duration (LD) contract of up to five years. Then, if they want to stay in the Organization, staff members must apply, usually once a year, and before the end of their LD contract, for an indefinite contract (IC) post. All candidates for an IC post are considered by the Review Board for the award of indefinite contracts (Review Board) which will choose the most suita...

    Full Text Available Joint instability creates a clinical and economic burden in the health care system. Injuries and disorders that directly damage the joint structure or lead to joint instability are highly associated with osteoarthritis (OA. Thus, understanding the physiology of joint stability and the mechanisms of joint instability-induced OA is of clinical significance. The first section of this review discusses the structure and function of major joint tissues, including periarticular muscles, which play a significant role in joint stability. Because the knee, ankle, and shoulder joints demonstrate a high incidence of ligament injury and joint instability, the second section summarizes the mechanisms of ligament injury-associated joint instability of these joints. The final section highlights the recent advances in the understanding of the mechanical and biological mechanisms of joint instability-induced OA. These advances may lead to new opportunities for clinical intervention in the prevention and early treatment of OA.

    The five contracts for Temporary Labour assignments on the CERN site (L020/PE, L 021/PE, L 022/PE, L 023/PE and L 024/PE) approved by the Finance Committee in March 1996 (CERN/FC/3857) reached the end of their initial three-year contractual period at the end of December 1999. At CERN?s request, in September 1999 the Finance Committee approved an extension of these contracts for the year 2000 for a total amount not exceeding 6 000 000 Swiss francs (CERN/FC/4196). In December 1999, one of the five contractors, FIRCROFT, withdrew from its contract for 2000. Following the satisfactory execution of the four remaining contracts during 2000, CERN requests approval to extend them from January 2001 for the second of the two optional years provided for in the original adjudication. The Finance Committee is invited to approve the extension of the existing contracts until 31 December 2001 for a total amount not exceeding 6 000 000 Swiss francs at 2000 prices.

  6. Amending Contracts for Choreographies

    Directory of Open Access Journals (Sweden)

    Laura Bocchi

    2011-07-01

    Full Text Available Distributed interactions can be suitably designed in terms of choreographies. Such abstractions can be thought of as global descriptions of the coordination of several distributed parties. Global assertions define contracts for choreographies by annotating multiparty session types with logical formulae to validate the content of the exchanged messages. The introduction of such constraints is a critical design issue as it may be hard to specify contracts that allow each party to be able to progress without violating the contract. In this paper, we propose three methods that automatically correct inconsistent global assertions. The methods are compared by discussing their applicability and the relationships between the amended global assertions and the original (inconsistent ones.

The new electricity market in Ontario has introduced the energy trader, who enters into a contract with the consumer, based on the spot price set by the Independent Electricity Market Operator. Every contract has a fixed price payer as well as floating-price payers. If the floating price for a given amount of energy is higher than the fixed price, then the consumer gets the difference. Confusion, however, arises with the purchase of retail physical power in the market, particularly in deciding a fixed rate that the consumer will be paying. Different billing options were also discussed with emphasis on mid to large retail customers that have portfolios in the tens of MW and up to 100 MW or more. figs.

These smart contracts are executed many, many times, always without real concurrency. First, all smart contracts are serially executed by miners before appending them to the blockchain. Later, those contracts are serially re-executed by validators to verify that the smart contracts were executed correctly by miners. Serial execution limits system throughput and fails ...

    Following a brief account of the puzzle that ethics committees present for the Western Philosophical tradition, I will examine the possibility that social contract theory can contribute to a philosophical account of these committees. Passing through classical as well as contemporary theories, particularly Rawls' recent constructivist approach, I will argue that social contract theory places severe constraints on the authority that may legitimately be granted to ethics committees. This, I conclude, speaks more about the suitability of the theory to this level of analysis than about the ethics committee phenomenon itself.

    2013-01-01

    Full Text Available Innervation zone (IZ has been identified as the origin of action potential propagation in isometric contraction. However, IZ shifts with changes in muscle length during muscle activity. The IZ shift has been estimated using raw EMG signals. This study aimed to investigate the movement of IZ location during continuous dynamic muscle contraction, using a computer program. Subjects flexed their elbow joint as repetitive dynamic muscle contractions. EMG signals were recorded from the biceps brachii muscle using an eight-channel surface electrode array. Approximately 100 peaks from EMG signals were detected for each channel and summed to estimate the IZ location. For each subject, the estimated IZ locations were subtracted from the IZ location during isometric contractions with the elbow flexed at 90°. The results showed that the IZ moved significantly with elbow joint movement from 45° to 135°. However, IZ movement was biased with only a 3.9 mm IZ shift on average when the elbow angle was acute but a 16 mm IZ shift on average when it was obtuse. The movement of IZ location during continuous dynamic muscle contraction can be investigated using this signal processing procedure without subjective judgment.

    developed meniscoids were fat pads, in the others, these were synovial meniscoids. Spines of younger individuals showed a predominance of synovial meniscoids with smooth surfaces that arched against the articular cavity. In spines of elderly individuals, meniscoids were rough, in some cases fibrous in structure, and had a lobulated or frayed edge. The shape, location of meniscoids and their presence in every joint indicate their definite role for the spine: they compensate the incongruence of articular surfaces, fill in empty spaces and facilitate spread of synovial fluid during translation movements. Variability in shape, size and location of meniscoids give support to the view that meniscoids developed secondarily in relation to the morphogenesis of articular surfaces and that they are fully adapted to the shape and function of the joint. Mobile meniscoids, particularly fibrous ones, can get wedged between articular surfaces due to a sudden, rush movement (entrapment theory) or can be caught between the edge of an articular surface and the articular capsule attachment (extrapment theory). This situation may result in either mechanical or functional blockade of the spine and a subsequent painful condition due to compression of nerves and reflex contraction of muscles. Direct evidence of such blockade and the validity of either hypothesis can today be provided by magnetic resonance imaging. All intervertebral joints, along the length of spine, possess capsule processes, i.e., meniscoids, which can be classified as synovial, fat and fibrous. Meniscoids are most developed in the lumbar and cervical spine. They serve to compensate for the incongruence of articular surfaces and to fill in empty spaces. Mobile, peduncular meniscoids can, at sudden or non-physiological movements, be caught between articular surfaces and cause spinal blockade and painful conditions. Manipulative treatment is, therefore, justified in indicated cases.

  11. Automatic Conflict Detection on Contracts

    Science.gov (United States)

    Fenech, Stephen; Pace, Gordon J.; Schneider, Gerardo

    Many software applications are based on collaborating, yet competing, agents or virtual organisations exchanging services. Contracts, expressing obligations, permissions and prohibitions of the different actors, can be used to protect the interests of the organisations engaged in such service exchange. However, the potentially dynamic composition of services with different contracts, and the combination of service contracts with local contracts can give rise to unexpected conflicts, exposing the need for automatic techniques for contract analysis. In this paper we look at automatic analysis techniques for contracts written in the contract language mathcal{CL}. We present a trace semantics of mathcal{CL} suitable for conflict analysis, and a decision procedure for detecting conflicts (together with its proof of soundness, completeness and termination). We also discuss its implementation and look into the applications of the contract analysis approach we present. These techniques are applied to a small case study of an airline check-in desk.

  12. Water and Muscle Contraction

    Directory of Open Access Journals (Sweden)

    Enrico Grazi

    2008-08-01

    Full Text Available The interaction between water and the protein of the contractile machinery as well as the tendency of these proteins to form geometrically ordered structures provide a link between water and muscle contraction. Protein osmotic pressure is strictly related to the chemical potential of the contractile proteins, to the stiffness of muscle structures and to the viscosity of the sliding of the thin over the thick filaments. Muscle power output and the steady rate of contraction are linked by modulating a single parameter, a viscosity coefficient. Muscle operation is characterized by working strokes of much shorter length and much quicker than in the classical model. As a consequence the force delivered and the stiffness attained by attached cross-bridges is much larger than usually believed.

    The article discusses the status of energy contracting in Switzerland and compares it with the situation in USA, Germany and France, where it has been standard practice for many years. The fact that this financing and operating instrument is not widely used in Switzerland in spite of its benefits for users and suppliers is discussed, as are the obstacles placed in its way. The results of a study made by the Federal Office of Energy are presented, whereby some 220 existing contracting arrangements with a total investment volume of around CHF 200 million were noted and a further potential of around CHF 1.1 billion estimated. The author notes that in order to utilise this potential, great efforts must be made by all parties involved

  17. Between Status and Contract?

    Directory of Open Access Journals (Sweden)

    Thorsten Keiser

    2013-01-01

    Full Text Available This contribution deals with unfree labour in Germany from the early modern age until the beginning of the 20th century. It presents the main conclusions of a book published in 2013 on this subject in German. Unfree labour is not identified in the first place with slavery or any other labour relationship based on status. Instead, this study aims at an analysis of freedom and coercion in contractual labour relationships. It will be argued that in Germany contractual labour relationships before 1800 were embedded in a legal system that strongly restricted contractual autonomy and aimed at the suppression of free labour markets. The scope of this legislation was to guarantee efficient labour performance, which was not only perceived as being in the personal interest of an employer, but as a fundamental element of the common good. After 1800 the system changed to more incentive-based legislation that established freedom of contract for labour relations. Nevertheless, coercion in order to perform the contractual duties of a work contract remained important for many groups of workers, especially farmhands and industrial workers. The last criminal sanctions for breaches of labour contracts were only abolished in the revolution of 1919. This development shows the difficulties German law had in extending the principles of private law to workers. When a system of free labour was fully established, the issue of unemployment and economic problems, especially in the Weimar Republic, required a new system of protective rules. The history of free market based labour contracts in Germany was therefore very short, with state intervention shi ing from control and coercion to social assistance.

    Full Text Available Objective to study the procedure of exiting the contract its costs and benefits. Methods statistical method comparative analysis. Results free exit from contract is one of the most powerful tools for the consumer rights protection. The procedure frees consumers from bad deals and keeps businesses honest. Yet consumers often choose transactions with lockin provisions trading off exit rights for other perks. This article examines the costs and benefits of free exit as compared to the lockin alternative. According to the authors the present regulation of exit penalties in the USA is poorly tailored to address concerns about lockin particularly in light of increasingly ubiquitous marketbased solutions. The article also calls regulatory attention to loyalty rewards which are shown to be as powerful as exit penalties and equally detrimental. Scientific novelty the article reveals a paradoxical state of the law exit regulations in the USA are used most where they are needed least. Termination penalties present an obvishyous target for regulatory intervention while loyalty programs seem benign not warranting any regulatory attention. Practical significance the article is of interest for the Russian juridical science and lawmaking authorities as in Russia the issue of exiting the contract is as topical as in the USA and requires solution which would impair neither the rights of consumers nor the rights of the sellers ofnbspproducts and services. nbsp

  1. Non-turnkey contract

    International Nuclear Information System (INIS)

    Shimoyama, Shunji

    1975-01-01

    A turnkey contract is recommended to such a country which is in the initial stage of nuclear power development with respect to a few plants being constructed earlier. The prime contractor may not necessarily be a reactor supplier. In some cases an architect engineering company may be a contractor. If this arrangement is not possible and the contract had to be a non-turnkey type, there might be some advantage to such a developing country capable of undertaking some major portions of the project works. Even if she might face with troubles and difficulties during construction of the first nuclear power station, she might have chance of aquiring technical kowledge and experience which would later enable her to make the plant of her own manufacture. In such a case it is advisable to limit the number of main contracts as small as possible and to utilize an organization to assist the owner in project management or to assume this function in his behalf.

  3. Why radiologists lose their hospital contracts: is your contract secure?

    Science.gov (United States)

    Muroff, Lawrence R

    2010-03-01

    Previously, a hospital contract meant tenure for the incumbent group of radiologists; however, those days are long gone. Exclusive contracts have morphed into exclusive contracts with carve-outs. Turf erosion has become a fact of life for radiology practices. Now radiologists are losing their hospital contracts in record numbers. Group size, though helpful for a variety of reasons, does not ensure that a practice will be secure in its hospital setting. The reasons that groups lose their hospital contracts are varied, and in this paper, the author discusses the most common ones. Suggestions to help practices avoid this unfortunate fate are presented.

    The purpose of this paper is to explore the readiness of contracted and non-contracted first-level healthcare facilities in Pakistan to deliver quality maternal and neonatal health (MNH) care. A balanced scorecard (BSC) was used as the assessment framework. Using a cross-sectional study design, two rural health centers (RHCs) contracted out to Aga Khan Health Service, Pakistan were compared with four government managed RHCs. A BSC was designed to assess RHC readiness to deliver good quality MNH care. In total 20 indicators were developed, representing five BSC domains: health facility functionality, service provision, staff capacity, staff and patient satisfaction. Validated data collection tools were used to collect information. Pearson χ2, Fisher's Exact and the Mann-Whitney tests were applied as appropriate to detect significant service quality differences among the two facilities. Contracted facilities were generally found to be better than non-contracted facilities in all five BSC domains. Patients' inclination for facility-based delivery at contracted facilities was, however, significantly higher than non-contracted facilities (80 percent contracted vs 43 percent non-contracted, p=0.006). The study shows that contracting out initiatives have the potential to improve MNH care. This is the first study to compare MNH service delivery quality across contracted and non-contracted facilities using BSC as the assessment framework.

  10. When your contract manufacturer becomes your competitor.

    Science.gov (United States)

    Arruñda, Benito; Vázquez, Xosé H

    2006-09-01

    PC maker Lenovo started out as a distributor of equipment made by IBM and other companies; now it has formed a joint venture with IBM and will eventually affix its own logo to its computers. Shanghai Automotive Industry Corporation (SAIC) started out manufacturing vehicles for Volkswagen and GM; now it's preparing to sell its own cars in China, Europe, and North America. Lenovo and SAIC represent a host of formerly anonymous makers of brand-name products that are breaking out of their defined roles and pushing the brands themselves aside. In this article, the authors explore the double-edged relationships original equipment manufacturers (OEMs) forge with their contract manufacturers (CMs). On the one hand, an OEM can reduce its labor costs, free up capital, and improve worker productivity by outsourcing all the manufacturing of a product. The company can then concentrate on value-adding activities--research and development, product design, and marketing, for instance. On the other hand, an OEM that retains a contract manufacturer may find itself immersed in a melodrama replete with promiscuity (the ambitious CM pursues liaisons with other OEMs), infidelity (the OEM's retailers and distributors shift their business to the upstart CM), and betrayal (the brazen CM transmits the OEM's intellectual property to the OEM's rivals or keeps it for itself when the contract is up). OEMs cannot simply terminate their outsourcing arrangements--they need contract manufacturers in order to keep specializing, adding value, and staying competitive. But OEMs can manage these relationships so that they don't become weak or the CMs too strong. Doing so requires modesty about revealing trade secrets; caution about whom one consorts with; and a judicious degree of intimacy, loyalty, and generosity toward partners and customers.

  11. Analysis of foreign petroleum contracts

    International Nuclear Information System (INIS)

    Moran, S.S.

    1991-01-01

    Most foreign exploration and production contracts are of two basic types: Production-Sharing contracts in which a portion of oil revenues, 'cost oil,' is available to the contractor for recoupment of exploration and production costs with the remainder, 'profit oil,' being shared according to an agreed-upon formula, and the familiar Tax-Royalty contract in which a share of petroleum revenues goes to the host country 'off the top' as royalties, and operating profits are taxed at the going rate. Bottom line splits of profits between host governments and contractors, which are approximately 50-50 in the United States, are typically in the 60-40 to 85-15 range elsewhere, with lower profit shares being offset by the higher volume potential and lower costs that may be associated with less mature exploration areas. Foreign contract qualities can be grossly compared by walking typical field models through the contracts to arrive at the bottom line profit splits. Variations within the contract forms include government participation, sliding scale contract elements, special taxes related to rates of return, etc. Often, contract terms are subject to negotiation and the tradeoffs between contract elements must be understood. Contract life, amortization schedules, fund repatriation, currency exchange rates, and the interaction of foreign and United States tax regimens are among the other factors that must be considered. Final decisions on foreign ventures must combine consideration of contracts, economic projections, hydrocarbon volumes, exploration cost estimates, and the estimated probability of success into an overall project assessment

  16. Contract Management of LHC Civil Engineering at Point 5

    CERN Document Server

    Osborne, J A

    1999-01-01

    Civil engineering work commenced in August 1998 at LEP Point 5 for the underground and surface works necessary to accommodate the CMS detector for the LHC project. The principal underground works consist of two parallel caverns, separated by a support pillar, two new shafts, a number of smaller connection and service galleries and tunnel enlargements on the existing LEP tunnel. The surface works consist of the 140 m long SX building for the detector assembly and numerous other steel and concrete structures necessary for the installation and operation of CMS. The civil engineering design and supervision has been awarded to a joint venture of Gibb (UK), SGI (Switzerland) and Geoconsult (Austria), and the contracting to a joint venture of Dragados (Spain) and Seli (Italy) for 112 MCHF. The aim of this paper is to discuss the management of this contract and in particular how the various parties interact in order to work most efficiently.

  17. The Lanthanide Contraction Revisited

    Energy Technology Data Exchange (ETDEWEB)

    Seitz, Michael; Oliver, Allen G.; Raymond, Kenneth N.

    2007-04-19

    A complete, isostructural series of lanthanide complexes (except Pm) with the ligand TREN-1,2-HOIQO has been synthesized and structurally characterized by means of single-crystal X-ray analysis. All complexes are 1D-polymeric species in the solid state, with the lanthanide being in an eight-coordinate, distorted trigonal-dodecahedral environment with a donor set of eight unique oxygen atoms. This series constitutes the first complete set of isostructural lanthanide complexes with a ligand of denticity greater than two. The geometric arrangement of the chelating moieties slightly deviates across the lanthanide series, as analyzed by a shape parameter metric based on the comparison of the dihedral angles along all edges of the coordination polyhedron. The apparent lanthanide contraction in the individual Ln-O bond lengths deviates considerably from the expected quadratic decrease that was found previously in a number of complexes with ligands of low denticity. The sum of all bond lengths around the trivalent metal cation, however, is more regular, showing an almost ideal quadratic behavior across the entire series. The quadratic nature of the lanthanide contraction is derived theoretically from Slater's model for the calculation of ionic radii. In addition, the sum of all distances along the edges of the coordination polyhedron show exactly the same quadratic dependency as the Ln-X bond lengths. The universal validity of this coordination sphere contraction, concomitant with the quadratic decrease in Ln-X bond lengths, was confirmed by reexamination of four other, previously published, almost complete series of lanthanide complexes. Due to the importance of multidentate ligands for the chelation of rare-earth metals, this result provides a significant advance for the prediction and rationalization of the geometric features of the corresponding lanthanide complexes, with great potential impact for all aspects of lanthanide coordination.

  20. Contractions from grading

    Science.gov (United States)

    Krishnan, Chethan; Raju, Avinash

    2018-04-01

    We note that large classes of contractions of algebras that arise in physics can be understood purely algebraically via identifying appropriate Zm-gradings (and their generalizations) on the parent algebra. This includes various types of flat space/Carroll limits of finite and infinite dimensional (A)dS algebras, as well as Galilean and Galilean conformal algebras. Our observations can be regarded as providing a natural context for the Grassmann approach of Krishnan et al. [J. High Energy Phys. 2014(3), 36]. We also introduce a related notion, which we call partial grading, that arises naturally in this context.

  5. IPP fuel contracts - creating certain contracts for uncertain times

    Coddington, I. [Coddington International Pty. Ltd., Milsons Point, NSW (Australia)

    1998-12-31

    Coal contracts for the new Asian Independent Power Producers (IPPs) are examined. Since most IPPs will be selling to state electricity utilities, often in competition with power plant using other fuels, coal based IPPs must negotiate advantageous coal supply contracts several years before the commissioning of a plant, and must ensure security of supply for at least the life of the construction loan. A more recent trend in the developed world is the Merchant IPP, where there is no guaranteed electricity sale. Lenders are wary of IPPs relying an imported coal, and insist on binding fuel contracts, while coal companies are wary of the quantity of information demanded by these lenders. A full understanding of the risks involved is needed; and a method of price indexation for the contracts. Contracts must also specify security of supply, coal quality, freight contracts and other details. 2 figs.

    While the object of nuclear contracts is specific, these contracts are concluded according to proven techniques based on general regulations on contracts. Following a review of contract classification, they are differentiated according to the nature of the co-contracting parties, the purpose of the contract itself, the procedure for drawing up the contracts, and payment. The operations prior to the contract vary in that they may include a call for tenders, an option for delays or a letter of intent. (NEA) [fr

    2012-01-01

    TraceContract is an API (Application Programming Interface) for trace analysis. A trace is a sequence of events, and can, for example, be generated by a running program, instrumented appropriately to generate events. An event can be any data object. An example of a trace is a log file containing events that a programmer has found important to record during a program execution. Trace - Contract takes as input such a trace together with a specification formulated using the API and reports on any violations of the specification, potentially calling code (reactions) to be executed when violations are detected. The software is developed as an internal DSL (Domain Specific Language) in the Scala programming language. Scala is a relatively new programming language that is specifically convenient for defining such internal DSLs due to a number of language characteristics. This includes Scala s elegant combination of object-oriented and functional programming, a succinct notation, and an advanced type system. The DSL offers a combination of data-parameterized state machines and temporal logic, which is novel. As an extension of Scala, it is a very expressive and convenient log file analysis framework.

  10. UKAEA'S evolving contract philosophy

    International Nuclear Information System (INIS)

    Nicol, R. D.

    2003-01-01

    The United Kingdom Atomic Energy Authority (UKAEA) has gone through fundamental change over the last ten years. At the heart of this change has been UKAEA's relationship with the contracting and supply market. This paper describes the way in which UKAEA actively developed the market to support the decommissioning programme, and how the approach to contracting has evolved as external pressures and demands have changed. UKAEA's pro-active approach to industry has greatly assisted the development of a healthy, competitive market for services supporting decommissioning in the UK. There have been difficult changes and many challenges along the way, and some retrenchment was necessary to meet regulatory requirements. Nevertheless, UKAEA has sustained a high level of competition - now measured in terms of competed spend as a proportion of competable spend - with annual out-turns consistently over 80%. The prime responsibility for market development will pass to the new Nuclear Decommissioning Authority (NDA) in 2005, as the owner, on behalf of the Government, of the UK's civil nuclear liabilities. The preparatory work for the NDA indicates that the principles established by UKAEA will be carried forward. (author)

  16. Tenure security, social relations and contract choice: Endogenous matching in the Chinese land rental market

    Science.gov (United States)

    Ma, Xianlei; Zhou, Yuepeng; Shi, Xiaoping

    2017-04-01

    In China, land rental transactions have increased considerably since the 1990s, but there exists a high degree of segmentation and informal features. The rental transactions between partners with close social relations and the use of informal contracts remain a common phenomenon in many regions, which strongly reduce the potential of the land rental market to enhance productivity and equity. The current literature postulates that the insecurity of land property rights may restrict land transactions between members of same social relations. Studies conducted in China show that the land rentals between partners with closer social relations prefer informal contracts because these contracts are self-enforced based on trust and reputation. However, little literature has jointly examined the effect of land tenure security and social relations on joint decisions of partner and contract choice in the Chinese land rental market. Based on household data collected in Jiangxi and Liaoning provinces in 2015, this paper aims to examine the relationship between land tenure security perceptions, social relation and land rental contract choices in China. We differentiate between formal and informal contracts of land rental activities because they have different enforcement mechanisms and thus different risk-sharing strategy. With regards to social relations, we differ among relatives, villagers living in the same village and strangers according to social distance. In order to reduce estimation bias without accounting for endogenous matching between landlords and tenants, we investigate the joint partner and contract choices in the land rental market using a nested logit framework. The paper contributes to the literature on the effect of tenure security and social relations on land rental contracts by (i) taking into account endogenous matching between landlords and tenants, and estimating the joint decisions of partner and contract choice, and (ii) examining the effect of perceived

However, these factors are widely assumed to be independent of each other and the few studies that dealt with interactions of torque, angle and angular velocity are based on isolated single-joint movements. Thus, the purpose of this study was to determine force/torque-angle and force/torque-angular velocity properties for multi-joint leg extensions. Human leg extension was investigated (n = 18) on a motor-driven leg press dynamometer while measuring external reaction forces at the feet. Extensor torque in the knee joint was calculated using inverse dynamics. Isometric contractions were performed at eight joint angle configurations of the lower limb corresponding to increments of 10° at the knee from 30 to 100° of knee flexion. Concentric and eccentric contractions were performed over the same range of motion at mean angular velocities of the knee from 30 to 240° s(-1). For contractions of increasing velocity, optimum knee angle shifted from 52 ± 7 to 64 ± 4° knee flexion. Furthermore, the curvature of the concentric force/torque-angular velocity relations varied with joint angles and maximum angular velocities increased from 866 ± 79 to 1,238 ± 132° s(-1) for 90-50° knee flexion. Normalised eccentric forces/torques ranged from 0.85 ± 0.12 to 1.32 ± 0.16 of their isometric reference, only showing significant increases above isometric and an effect of angular velocity for joint angles greater than optimum knee angle. The findings reveal that force/torque production during multi-joint leg extension depends on the combined effects of angle and angular velocity. This finding should be accounted for in modelling and optimisation of human movement.

    Full Text Available With the long construction period, the giant scope and complex technology, water conservancy and hydroelectric engineering construction has large investment. In the fully competitive water conservancy and hydropower project construction contracting market, it is almost impossible for a company to contract with a water conservancy and hydropower project independently. Therefore, water conservancy and hydropower project construction can be contracted by several construction companies together, to play each company's strengths, lower offer, improve project quality, shorten the construction period and win the competition. In this paper, we started from the definition of Joint Venture, summed up the forms of Joint Venture in water conservancy and hydropower engineering, proposed that the JV modes can be divided into domestic and international union, tight mode, half-tight mode, loose mode, incorporation and consortium. Furthermore, we analyzed the advantages and disadvantages of Joint Venture. Put forward that the JV can relieve the owner from interfacial administrative work, reduce risk of engineering, and raise the success rate of engineering contract, improve the correctness of price and increase the opportunity of project contracting, Learn from other members, enhance technology and management and make full use of idle resources

    Empirical studies on incentive contracts have primarily been concerned with the effects on employees’ productivity and earnings. The productivity increases associated with such contracts may, however, come at the expense of quality of life at or outside work. In this paper we study the effect on the employees’ non-work activities, testing whether incentive contracts lead to a change in the allocation of time across work and non-work activities. In doing so, we distinguish between two effects,...

    The paper presents a cut-elimination procedure for intuitionistic propositional logic in which cut is eliminated directly, without introducing the multiple-cut rule mix, and in which pushing cut above contraction is one of the reduction steps. The presentation of this procedure is preceded by an analysis of Gentzen's mix-elimination procedure, made in the perspective of permuting cut with contraction. It is also shown that in the absence of implication, pushing cut above contraction doesn't p...

    The Work and Minor Work contracts are all of the result-oriented type. The work is specified by CERN and the contractor is given full responsibility for its performance. The contracts are thus very similar to supply contracts. The re-tendering of the existing contracts is almost complete, except for some building maintenance contracts. A new cycle of re-tendering for some activities will be launched in the next twelve months. The total estimated expenditure in the year 2000 for the contracts referred to in this document is 27 750 000 Swiss francs at 1999 prices. The Finance Committee is invited: - to approve the proposed expenditure for the extension of contracts for which the estimated amount for the year 2000 exceeds 750 000 Swiss francs, namely those under references 1, 2, 3, 5, 7, 8, 9 and 23, highlighted in Table I; - to take note that all Work and Minor Work contracts have been tendered since 1 January 1994, except the small contracts shown under references 12 and 16 in Table I; - to take note that the ...

    2011-01-01

    Sweden signed Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) September 29, 1997. Sweden ratified the Joint Convention about two years later and is a Contracting Party to the Joint Convention since July 29, 1999. The Joint Convention entered into force on June 18, 2001. Each member nation having ratified the Joint Convention (Contracting Party) is obligated to prepare a National Report covering the scope of the Joint Convention and subject it to review by other Contracting Parties at Review Meetings held in Vienna, Austria. Sweden participated in the First Review Meeting in November 2003, the Second Review Meeting in May 2006 and the Third Review Meeting in May 2009. This report is the fourth Swedish National Report under the Joint Convention. This report satisfies the requirements of the Joint Convention for reporting on the status of safety at spent fuel and radioactive waste management facilities within Sweden. It constitutes an updated document with basically the same structure as the previous national reports under the terms of the Joint Convention and reflects developments in Sweden through December 2010. It will be subject to review at the Fourth Review Meeting of the Contracting Parties in Vienna, Austria, in May 2012

  13. The Relationship between the Employment Contract and other Civil Contracts

    Directory of Open Access Journals (Sweden)

    Răzvan Radu Popescu

    2015-05-01

    Full Text Available The employment relationship is a contractual one and as such must have all the basic elements of an enforceable contract to make it legally binding. In strict contractual terms, the offer is made by the employer and formally accepted by the employee. Once the acceptance has taken place, there is a legally binding agreement and an action will lie against the party who breaches that agreement, even though it may only just have come into existence. An employment contract, however, is unlike most other contracts. Although the parties will have negotiated the main terms, we shall see that a large number of terms will be implied into the agreement from all sorts of different sources and will not have been individually negotiated by the parties at all. This is what makes an employment contract so different from other contracts. We think this article is an important step in the disclosure of the problem eraised by these two concepts.

  14. Age-related differences in muscle fatigue vary by contraction type: a meta-analysis.

    Science.gov (United States)

    Avin, Keith G; Law, Laura A Frey

    2011-08-01

    During senescence, despite the loss of strength (force-generating capability) associated with sarcopenia, muscle endurance may improve for isometric contractions. The purpose of this study was to perform a systematic meta-analysis of young versus older adults, considering likely moderators (ie, contraction type, joint, sex, activity level, and task intensity). A 2-stage systematic review identified potential studies from PubMed, CINAHL, PEDro, EBSCOhost: ERIC, EBSCOhost: Sportdiscus, and The Cochrane Library. Studies reporting fatigue tasks (voluntary activation) performed at a relative intensity in both young (18-45 years of age) and old (≥ 55 years of age) adults who were healthy were considered. Sample size, mean and variance outcome data (ie, fatigue index or endurance time), joint, contraction type, task intensity (percentage of maximum), sex, and activity levels were extracted. Effect sizes were (1) computed for all data points; (2) subgrouped by contraction type, sex, joint or muscle group, intensity, or activity level; and (3) further subgrouped between contraction type and the remaining moderators. Out of 3,457 potential studies, 46 publications (with 78 distinct effect size data points) met all inclusion criteria. A lack of available data limited subgroup analyses (ie, sex, intensity, joint), as did a disproportionate spread of data (most intensities ≥ 50% of maximum voluntary contraction). Overall, older adults were able to sustain relative-intensity tasks significantly longer or with less force decay than younger adults (effect size=0.49). However, this age-related difference was present only for sustained and intermittent isometric contractions, whereas this age-related advantage was lost for dynamic tasks. When controlling for contraction type, the additional modifiers played minor roles. Identifying muscle endurance capabilities in the older adult may provide an avenue to improve functional capabilities, despite a clearly established decrement in

    Biological sutures are joints which connect two stiff skeletal or skeletal-like components. These joints possess a wavy geometry with a thin organic layer providing adhesion. Examples of biological sutures include mammalian skulls, the pelvic assembly of the armored fish Gasterosteus aculeatus (the three-spined stickleback), and the suture joints in the shell of the red-eared slider turtle. Biological sutures allow for movement and compliance, control stress concentrations, transmit loads, reduce fatigue stress and absorb energy. In this investigation, the mechanics of the role of suture geometry in providing a naturally optimized joint is explored. In particular, analytical and numerical micromechanical models of the suture joint are constructed. The anisotropic mechanical stiffness and strength are studied as a function of suture wavelength, amplitude and the material properties of the skeletal and organic components, revealing key insights into the optimized nature of these ubiquitous natural joints.

    Tessier, C

    1992-03-01

    Contract medical transcription services can be of great assistance in meeting the demands for transcription, without jeopardizing patient, physician, or institutional confidentiality. You simply must require the contract service to provide at least the same degree of protection and preservation of confidentiality that you should require inhouse. To achieve this you must make these requirements explicit, comprehensive, comprehensible, believable, and enforceable. Discuss the requirements with prospective contractors. Review them at least annually with existing contractors and when contracts are due for renewal. Be sure to specify the consequence of breaching confidentiality, and if there are breaches, enforce the terms of the contract. Consult your institution's legal counsel both in developing the contract and in enforcing its provisions. Take into consideration your department's and institution's policies, AHIMA's statement on confidentiality, as well as local, state, and federal laws. Above all, never lose sight of the patient. Ultimately, it is not patient information that you are obligated to protect. It is the patient.

  4. Choreography Synthesis as Contract Agreement

    Directory of Open Access Journals (Sweden)

    Julien Lange

    2013-10-01

    Full Text Available We propose a formal model for distributed systems, where each participant advertises its requirements and obligations as behavioural contracts, and where multiparty sessions are started when a set of contracts allows to synthesise a choreography. Our framework is based on the CO2 calculus for contract-oriented computing, and borrows concepts and results from the session type literature. It supports sessions where the number of participants is not determined beforehand, and keeps CO2's ability to rule out participants that are culpable if contracts are not fulfilled at runtime. We show that we have progress and session fidelity in CO2, as a result of the honesty of participants — i.e., their ability to always adhere to their contracts.

  5. Standard form contracts and a smart contract future

    2018-05-01

    Full Text Available With a budding market of widespread smart contract implementation on the horizon, there is much conversation about how to regulate this new technology. Discourse on standard form contracts (SFCs and how they have been adopted in a digital environment is useful toward predicting how smart contracts might be interpreted. This essay provides a critical review of the discourse surrounding digitised SFCs and applies it to issues in smart contract regulation. An exploration of the literature surrounding specific instances SFCs finds that it lacks a close examination of the textual and documentary aspects of SFCs, which are particularly important in a digital environment as a shift in medium prompts a different procedural process. Instead, common perspectives are either based on outdated notions of paper versions of these contracts or on ideologies of industry and business that do not sufficiently address the needs of consumers/users in the digital age. Most importantly, noting the failure of contract law to address the inequities of SFCs in this environment can help prevent them from being codified further with smart contracts.

    2017-01-01

    Over the last twenty years we have witnessed a growing focus on the rights of the ill people. The debate on informed consent and a new redefinition of the therapeutic relationship is constantly evolving. With this article, we propose a critical literature review of the so-called "Ulysses contract" or "psychiatric advance directives". It refers to the will that a subject expresses in writing, or orally, about the treatments he or she wishes or does not wish to be subject to if the time comes when it may be impossible to express his/her consent. This can especially occur in those with psychiatric disorders with serious clinical involvement and remitting-relapse (typically bipolar disorder, but also chronic delusional disorders and schizophrenia). In this context, the question is whether during intercritical periods the patient may or may not leave instructions to their care-givers. This aspect opens up to a series of interdisciplinary problems. In this article, we want to show the complexity of this debate from a clinical, ethical, legal and psychodynamic point of view, emphasizing the strengths and the major criticisms of the psychiatric advance directives for each area.

    Maggs, William Ward

    A new agreement provides $220 million for development and construction of the Landsat 6 remote sensing satellite and its ground systems. The contract, signed on March 31, 1988, by the Department of Commerce (DOC) and the Earth Observation Satellite (EOSAT) Company of Lanham, Md., came just days after approval of DOC's Landsat commercialization plan by subcommittees of the House and Senate appropriations committees.The Landsat 6 spacecraft is due to be launched into orbit on a Titan II rocket in June 1991 from Vandenburg Air Force Base, Calif. The satellite will carry an Enhanced Thematic Mapper (ETM) sensor, an instrument sensitive to electromagnetic radiation in seven ranges or bands of wavelengths. The satellite's payload will also include the Sea Wide Field Sensor (Sea-WiFS), designed to provide information on sea surface temperature and ocean color. The sensor is being developed in a cooperative effort by EOSAT and the National Aeronautics and Space Administration (NASA). A less certain passenger is a proposed 5-m resolution, three-band sensor sensitive to visible light. EOSAT is trying to find both private financing for the device and potential buyers of the high-resolution imagery that it could produce. The company has been actively courting U.S. television networks, which have in the past used imagery from the European Système Probatoire d'Observation de la Terre (SPOT) satellite for news coverage.

    Columnar joints form by cracking during cooling-induced contraction of lava, allowing hydrothermal fluid circulation. A lack of direct observations of their formation has led to ambiguity about the temperature window of jointing and its impact on fluid flow. Here we develop a novel thermo-mechanical experiment to disclose the temperature of columnar jointing in lavas. Using basalts from Eyjafjallajökull volcano (Iceland) we show that contraction during cooling induces stress build-up below the solidus temperature (980 °C), resulting in localised macroscopic failure between 890 and 840 °C. This temperature window for incipient columnar jointing is supported by modelling informed by mechanical testing and thermal expansivity measurements. We demonstrate that columnar jointing takes place well within the solid state of volcanic rocks, and is followed by a nonlinear increase in system permeability of <9 orders of magnitude during cooling. Columnar jointing may promote advective cooling in magmatic-hydrothermal environments and fluid loss during geothermal drilling and thermal stimulation.

  20. The implications of being novated into joint operating agreements

    Yaworski, B.A. [Field Atkinson Perraton, Calgary, AB (Canada)

    1999-05-01

    The common law of `novation` was examined. Novation involves the making of a new contract in substitution of the original contract, thereby creating contractual privity between the assignee and the creditor. It is not a transfer of a liability from the original debtor (assignor) to the assignee, but rather it is a new contract in place or substitution of the old contract, thereby extinguishing the original debtor`s obligation to the creditor and creating a new obligation between the assignee and the creditor. The concept of novation is reviewed as it relates to the oil and gas industry before and after the introduction of the Industry Agreement Assignment Procedure. The implications of being novated into joint operating agreements are explained and the restraints on alienation and the exemptions in common oil and gas agreements are reviewed. Compliance issues, and certain practical considerations of novation are also examined.

    Contractures of the knee joint cause disability and handicap. Recovering range of motion is recognized by arthritic patients as their preference for improved health outcome secondary only to pain management. Clinical and experimental studies provide evidence that the posterior knee capsule prevents the knee from achieving full extension. This study was undertaken to investigate the dynamic changes of the joint capsule transcriptome during the progression of knee joint contractures induced by immobilization. We performed a microarray analysis of genes expressed in the posterior knee joint capsule following induction of a flexion contracture by rigidly immobilizing the rat knee joint over a time-course of 16 weeks. Fold changes of expression values were measured and co-expressed genes were identified by clustering based on time-series analysis. Genes associated with immobilization were further analyzed to reveal pathways and biological significance and validated by immunohistochemistry on sagittal sections of knee joints. Changes in expression with a minimum of 1.5 fold changes were dominated by a decrease in expression for 7732 probe sets occurring at week 8 while the expression of 2251 probe sets increased. Clusters of genes with similar profiles of expression included a total of 162 genes displaying at least a 2 fold change compared to week 1. Functional analysis revealed ontology categories corresponding to triglyceride metabolism, extracellular matrix and muscle contraction. The altered expression of selected genes involved in the triglyceride biosynthesis pathway; AGPAT-9, and of the genes P4HB and HSP47, both involved in collagen synthesis, was confirmed by immunohistochemistry. Gene expression in the knee joint capsule was sensitive to joint immobility and provided insights into molecular mechanisms relevant to the pathophysiology of knee flexion contractures. Capsule responses to immobilization was dynamic and characterized by modulation of at least three

  4. Food and drink serving contract

    2012-01-01

    Full Text Available Food and drink catering service is almost as old as the civilization itself. Even though this vocation is a part of the catering activity, Serbian law does not foresee this contract section as personalized. Key legal sources for this kind of contract are business customs. Food and drink serving contract is a mixed-type contract and its legal nature is very interesting due to its complexity. Specific for this contract is the fact that it is not an ordinary service, but also an activity which requires a degree of culinary skills, knowledge of customs of other nations, as well as other skills. The very category of a good professional in business economy / hospitality industry is very dynamic, as it needs to be evaluated according to all given circumstances, which may be rather unpredictable. By considering the legal nature, but also the rights and obligations of the contracting parties, we tried to point to the questions that require a special attention. Legal sources that indirectly refer to food and drink serving contracts were taken into account. Apart from the Law on Obligatory Relations, we also considered here the Law on Tourism also pointing to the comparative law and jurisprudence.

    Given a complex separable Hilbert space H and a contraction A on H such that A n , n≥2 some integer, is normal it is shown that if the defect operator D A = (1 - A * A) 1/2 is of the Hilbert-Schmidt class, then A is similar to a normal contraction, either A or A 2 is normal, and if A 2 is normal (but A is not) then there is a normal contraction N and a positive definite contraction P of trace class such that parallel to A - N parallel to 1 = 1/2 parallel to P + P parallel to 1 (where parallel to · parallel to 1 denotes the trace norm). If T is a compact contraction such that its characteristics function admits a scalar factor, if T = A n for some integer n≥2 and contraction A with simple eigen-values, and if both T and A satisfy a ''reductive property'', then A is a compact normal contraction.

  6. Aspects of research and development contract terms in the bio/pharmaceutical sector.

    Science.gov (United States)

    Banerjee, Tannista

    2012-01-01

    The cost of new drug development is increasing every year. Pharmaceutical companies use R&D joint ventures, mergers, and outsource different stages of pharmaceutical R&D activities for a faster and cost minimizing method of innovation. Pharmaceutical companies outsource R&D activities to independent small biotech or pharmaceutical companies that specialize in different stages of pharmaceutical R&D. This chapter examines the determinants of the payment structure of research contracts between large bio/pharmaceutical companies and specialized research firms. Determinants of R&D contracts are analyzed using detailed R&D contract data between bio/pharmaceutical companies and independent research firms for 10 years. A multinomial logit model is used in order to understand the determinants of three different types of contracts; royalty contracts, fixed payment contracts, and the mixed contracts. Under uncertainty, the likelihood of a royalty contract rises for the early stages of the research and with the patent stock of the research firm. It is more likely to observe both royalty and fixed payment if the pharmaceutical client has past contracts with the same research firm. The results also suggest that if Food and Drug Administration (FDA) is more stringent in any disease area in reviewing the new drug application, then the likelihood of signing pure royalty contract decreases. Understanding the nature of R&D contracts and the effects of FDA's behavior on the pharmaceutical R&D contract is important because these contracts not only affect the cost of new drug invention but also the quality and the rate of invention. VALUE: Results are useful for both the pharmaceutical companies and the economic/business researchers.

    2018-03-01

    In this paper we report, clarify and broaden various recent efforts to complement the chemistry-centered models of force generation in (skeletal) muscles by mechanics-centered models. The physical mechanisms of interest can be grouped into two classes: passive and active. The main passive effect is the fast force recovery which does not require the detachment of myosin cross-bridges from actin filaments and can operate without a specialized supply of metabolic fuel (ATP). In mechanical terms, it can be viewed as a collective folding-unfolding phenomenon in the system of interacting bi-stable units and modeled by near equilibrium Langevin dynamics. The active force generation mechanism operates at slow time scales, requires detachment and is crucially dependent on ATP hydrolysis. The underlying mechanical processes take place far from equilibrium and are represented by stochastic models with broken time reversal symmetry implying non-potentiality, correlated noise or multiple reservoirs. The modeling approaches reviewed in this paper deal with both active and passive processes and support from the mechanical perspective the biological point of view that phenomena involved in slow (active) and fast (passive) force generation are tightly intertwined. They reveal, however, that biochemical studies in solution, macroscopic physiological measurements and structural analysis do not provide by themselves all the necessary insights into the functioning of the organized contractile system. In particular, the reviewed body of work emphasizes the important role of long-range interactions and criticality in securing the targeted mechanical response in the physiological regime of isometric contractions. The importance of the purely mechanical micro-scale modeling is accentuated at the end of the paper where we address the puzzling issue of the stability of muscle response on the so called ‘descending limb’ of the isometric tetanus.

    A joint for use in electrochemical devices, such as solid oxide fuel cells (SOFCs), oxygen separators, and hydrogen separators, that will maintain a hermetic seal at operating temperatures of greater than 600.degree. C., despite repeated thermal cycling excess of 600.degree. C. in a hostile operating environment where one side of the joint is continuously exposed to an oxidizing atmosphere and the other side is continuously exposed to a wet reducing gas. The joint is formed of a metal part, a ceramic part, and a flexible gasket. The flexible gasket is metal, but is thinner and more flexible than the metal part. As the joint is heated and cooled, the flexible gasket is configured to flex in response to changes in the relative size of the metal part and the ceramic part brought about by differences in the coefficient of thermal expansion of the metal part and the ceramic part, such that substantially all of the tension created by the differences in the expansion and contraction of the ceramic and metal parts is absorbed and dissipated by flexing the flexible gasket.

  19. Space Suit Joint Torque Measurement Method Validation

    Science.gov (United States)

    Valish, Dana; Eversley, Karina

    2012-01-01

    In 2009 and early 2010, a test method was developed and performed to quantify the torque required to manipulate joints in several existing operational and prototype space suits. This was done in an effort to develop joint torque requirements appropriate for a new Constellation Program space suit system. The same test method was levied on the Constellation space suit contractors to verify that their suit design met the requirements. However, because the original test was set up and conducted by a single test operator there was some question as to whether this method was repeatable enough to be considered a standard verification method for Constellation or other future development programs. In order to validate the method itself, a representative subset of the previous test was repeated, using the same information that would be available to space suit contractors, but set up and conducted by someone not familiar with the previous test. The resultant data was compared using graphical and statistical analysis; the results indicated a significant variance in values reported for a subset of the re-tested joints. Potential variables that could have affected the data were identified and a third round of testing was conducted in an attempt to eliminate and/or quantify the effects of these variables. The results of the third test effort will be used to determine whether or not the proposed joint torque methodology can be applied to future space suit development contracts.

    In 1964 the FAO and IAEA decided to establish a joint programme for the specific purpose of assisting Member States in applying nuclear techniques to develop their food and agriculture. As a result, the Joint FAO/IAEA Division of Isotope and Radiation Applications of Atomic Energy and Agriculture Development was established. The objectives of this joint FAO/IAEA programme are to exploit the potential of isotopes and radiation applications in research and development to increase and stabilize agriculture production, to reduce production costs, to improve the quality of food, to protect agricultural products from spoilage and losses, and to minimize pollution of food and agricultural environment. The activities of the joint programme, which are briefly described, can be grouped under three main headings: co-ordination and support of research; technical assistance including training; and dissemination of information. Tables are shown giving a breakdown of 311 research contracts and agreements held with institutes in Member States and 86 technical assistance projects in 46 developing countries, providing training, expertise and specialized equipment

  1. A model to explain joint patterns found in ignimbrite deposits

    Science.gov (United States)

    Tibaldi, A.; Bonali, F. L.

    2018-03-01

    The study of fracture systems is of paramount importance for economic applications, such as CO2 storage in rock successions, geothermal and hydrocarbon exploration and exploitation, and also for a better knowledge of seismogenic fault formation. Understanding the origin of joints can be useful for tectonic studies and for a geotechnical characterisation of rock masses. Here, we illustrate a joint pattern discovered in ignimbrite deposits of South America, which can be confused with conjugate tectonic joint sets but which have another origin. The pattern is probably common, but recognisable only in plan view and before tectonic deformation obscures and overprints it. Key sites have been mostly studied by field surveys in Bolivia and Chile. The pattern is represented by hundreds-of-meters up to kilometre-long swarms of master joints, which show circular to semi-circular geometries and intersections that have "X" and "Y" patterns. Inside each swarm, joints are systematic, rectilinear or curvilinear in plan view, and as much as 900 m long. In section view, they are from sub-vertical to vertical and do not affect the underlying deposits. Joints with different orientation mostly interrupt each other, suggesting they have the same age. This joint architecture is here interpreted as resulting from differential contraction after emplacement of the ignimbrite deposit above a complex topography. The set of the joint pattern that has suitable orientation with respect to tectonic stresses may act to nucleate faults.

    The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

    Full Text Available The aim of this paper is to propose a new framework for structuring contract types and payment methods. Concerning procurement contracts, the first important new feature of this framework is a stepwise structure with three main steps in the contract design: (1 what will be procured—should the contract only include construction, or should it include both construction and operation/maintenance (2 who will do the detailed design of the premise and (3 how many contractors will the client use? The second important new feature of this framework is that both step 2 and step 3 include a continuum of alternatives. Concerning payment methods, the new framework is primarily based on how the specific risks of the project are shared. These frameworks can be useful for policy formulation in that they can help to avoid some problematic ways of formulating policies.

  19. Contracting and Performance in Agencies

    DEFF Research Database (Denmark)

    Bjørnholt, Bente; Houlberg Salomonsen, Heidi; Rennison, Betina Wolfgang

    As part of New Public Management (NPM), contracting represents a supplement to the traditional hierarchical and rule-based managing of relations between actors in order to improve performance (Fortin and van Hassel 2000; Greve and Ejersbo 2002; Drewry et al. 2005; Verhoest 2005). To various degrees...... higher goal attainment when agency head experience that the department balance dialogue and autonomy with some element of control in the process of internal contracting (Bjørnholt and Salomonsen 2011). This implies, that effective steering include a combination of decentralized management...... and how a balanced use of internal contracting leads to a better performance. These findings are then theoretically interpreted based upon a combination of literature on agencification as well as public management. We compare contracting across all Danish agencies based on a combination of survey...

  1. Contraction of the solar nebula

    International Nuclear Information System (INIS)

    Rawal, J.J.

    1984-01-01

    The concept of Roche limit is applied to the Laplacian theory of the origin of the solar system to study the contraction of a spherical gas cloud (solar nebula). In the process of contraction of the solar nebula, it is assumed that the phenomenon of supersonic turbulent convection is operative and brings about the halt at various stages of contraction. It is found that the radius of the contracting solar nebula follows the Titius-Bode law. The consequences of the relation are also discussed. The aim is to attempt to explain, on the basis of the concept of Roche limit, the distribution of planets in the solar system and try to understand the physics underlying it. (Auth.)

    Aleksandrova, N V; Shkolnikova, M A; Dlin, V V; Yugay, M T

    Analysis of publication activity in the field of biomedicine shows insignificant input of Russia in the world scientific product. This is largely due to the lack of incentives for researchers. Article describes stimulation of researchers in Russia, compares it with foreign models, formulates main shortcomings of support and stimulation of research in Russia and introduces the concept of effective contract. Development of personnel motivation and stimulation of employees of scientific and research organizations in the field of health. As a successful experience the article describes the implementation of effective contract in Veltishev Research and Clinical Institute for Pediatrics where for years remuneration of researchers depended upon their positions without consideration of research results. Effective contract brought significant changes in the traditional system setting new performance and efficiency criteria. New evaluation system took into account publication activity, presentation activity, implementation of research results, raising scientific personnel, thesis work and income-generating activities. Introduction of effective contract already in the second year led to a rise in the number of foreign publications, publications in journals with impact factor of more than 2, the general increase in the number of articles in peer-reviewed journals with impact factor more than 0.3, the growth of the number of articles by 1 researcher, Hirsch index improving both by individual employees and the entire Institute, increase of grant activity and presentation activity at top-rated professional congresses. The growth of publication and presentation activities has been achieved at the reduction of research staff by 23%. From financial viewpoint effective contract resulted in the redistribution of resources in favour of more efficient researchers. The introduction of effective contract and increase of requirements for scientific output did not cause resistance of staff

    Sacroiliac joint dysfunction is a disorder presenting with low back and groin pain. It should be taken into consideration during the preoperative differential diagnosis of lumbar disc herniation, lumbar spinal stenosis and facet syndrome. Four cases with sacroiliac dysfunction are presented. The clinical and radiological signs supported the evidence of sacroiliac dysfunction, and exact diagnosis was made after positive response to sacroiliac joint block. A percutaneous sacroiliac fixation provided pain relief in all cases. The mean VAS scores reduced from 8.2 to 2.2. It is concluded that sacroiliac joint dysfunction diagnosis requires a careful physical examination of the sacroiliac joints in all cases with low back and groin pain. The diagnosis is made based on positive response to the sacroiliac block. Sacroiliac fixation was found to be effective in carefully selected cases.

  18. Contract-Based Incentive Mechanism for Mobile Crowdsourcing Networks

    Directory of Open Access Journals (Sweden)

    Nan Zhao

    2017-09-01

    Full Text Available Mobile crowdsourcing networks (MCNs are a promising method of data collecting and processing by leveraging the mobile devices’ sensing and computing capabilities. However, because of the selfish characteristics of the service provider (SP and mobile users (MUs, crowdsourcing participants only aim to maximize their own benefits. This paper investigates the incentive mechanism between the above two parties to create mutual benefits. By modeling MCNs as a labor market, a contract-based crowdsourcing model with moral hazard is proposed under the asymmetric information scenario. In order to incentivize the potential MUs to participate in crowdsourcing tasks, the optimization problem is formulated to maximize the SP’s utility by jointly examining the crowdsourcing participants’ risk preferences. The impact of crowdsourcing participants’ attitudes of risks on the incentive mechanism has been studied analytically and experimentally. Numerical simulation results demonstrate the effectiveness of the proposed contract design scheme for the crowdsourcing incentive.

    This paper introduces a framework for joint hub network development. Building a joint physical hub for transhipment of goods is expensive and therefore involves considerable risks for the cooperating companies. In a practical setting, it is unlikely that an entire network will be built at once. Rather, the partners will have a more cautious attitude and build the hub facilities one-by-one. In the proposed framework, every time a new hub is introduced, partners will have the opportunity to dec...

    Prosthetic joint infections represent a major therapeutic challenge for both healthcare providers and patients. This paper reviews the predisposing factors, pathogenesis, microbiology, diagnosis, treatment and prophylaxis of prosthetic joint infection. The most optimal management strategy should be identified based on a number of considerations including type and duration of infection, antimicrobial susceptibility of the infecting pathogen, condition of infected tissues and bone stock, patient wishes and functional status.

    2018-06-01

    In reduced muscle preparations, the slack length and passive stiffness of muscle fibres have been shown to be influenced by previous muscle contraction or stretch. In human muscles, such behaviours have been inferred from measures of muscle force, joint stiffness and reflex magnitudes and latencies. Using ultrasound imaging, we directly observed that isometric contraction of the vastus lateralis muscle at short lengths reduces the slack lengths of the muscle-tendon unit and muscle fascicles. The effect is apparent 60 s after the contraction. These observations imply that muscle contraction at short lengths causes the formation of bonds which reduce the effective length of structures that generate passive tension in muscles. In reduced muscle preparations, stretch and muscle contraction change the properties of relaxed muscle fibres. In humans, effects of stretch and contraction on properties of relaxed muscles have been inferred from measurements of time taken to develop force, joint stiffness and reflex latencies. The current study used ultrasound imaging to directly observe the effects of stretch and contraction on muscle-tendon slack length and fascicle slack length of the human vastus lateralis muscle in vivo. The muscle was conditioned by (a) strong isometric contractions at long muscle-tendon lengths, (b) strong isometric contractions at short muscle-tendon lengths, (c) weak isometric contractions at long muscle-tendon lengths and (d) slow stretches. One minute after conditioning, ultrasound images were acquired from the relaxed muscle as it was slowly lengthened through its physiological range. The ultrasound image sequences were used to identify muscle-tendon slack angles and fascicle slack lengths. Contraction at short muscle-tendon lengths caused a mean 13.5 degree (95% CI 11.8-15.0 degree) shift in the muscle-tendon slack angle towards shorter muscle-tendon lengths, and a mean 5 mm (95% CI 2-8 mm) reduction in fascicle slack length, compared to the

  3. Benign joint hypermobility syndrome

    2014-11-01

    Full Text Available Benign joint hypermobility syndrome (BJHS, commonly known as loose ligament syndrome, is a non-inflammatory rheumatic condition. It is characterised by a greater than normal range of motion of the joints of the limbs and spine. The prevalence of the syndrome in preschool-age children is estimated to be between 2% and 30%, depending on ethnic background (with higher prevalence in Asian and African populations, occurring most often in families with a history of the condition and more frequently in girls. This paper presents a case report of a 12-year-old girl. A broad differential diagnostic approach to recurrent joint inflammation with joint effusion and pain made it possible to establish a diagnosis of benign joint hypermobility syndrome. The child met the Brighton criteria; her Beighton score was 7 out of 9. Patient education aimed at eliminating abnormal joint movement and an appropriate rehabilitation programme play key roles in the treatment of BJHS.

  4. Psychological contracts of hospice nurses.

    Science.gov (United States)

    Jones, Audrey Elizabeth; Sambrook, Sally

    2010-12-01

    Psychological contracts have been described as individuals' beliefs regarding the obligations, expectations, and contributions that exist between them and their employer. They can be influenced by the organization's culture and philosophy, through human resources policies, and through the employee's personality and characteristics. Owing to the recent economic crisis, hospices in the UK are currently in a transitional phase and are being expected to demonstrate efficiencies that might be more in line with a business model than a health-care environment. This may conflict with the philosophical views of hospice nurses. To support nurses through this transition, it might be helpful to understand the antecedents of hospice nurses' behaviour and how they construct their psychological contracts. Failure to offer adequate support might lead to negative outcomes such as a desire to leave the organisation, poorer quality work, or disruptive behaviour. This study used a modified grounded theory approach involving in-depth interviews to explore the context and content of the psychological contracts of hospice nurses in the UK. Four main themes emerged: the types of psychological contracts formed, how the contracts are formed, their contents, and the breaches and potential violations the nurses perceive.

    Full Text Available History of present illness: A 30-year-old male was brought in by ambulance to the emergency department as a trauma activation after a motorcycle accident. The patient was the helmeted rider of a motorcycle traveling at an unknown speed when he lost control and was thrown off his vehicle. He denied loss of consciousness, nausea, or vomiting. The patient’s vital signs were stable and his only complaint was pain around his left shoulder. On exam, the patient had a prominent left clavicle without skin compromise. He had adequate range of motion in the left shoulder with moderate pain, and his left upper extremity was neurovascularly intact. Significant findings: Plain films of the left shoulder showed elevation of the left clavicle above the acromion. There was an increase in the acromioclavicular (AC and coracoclavicular (CC distances (increased joint distances marked with red and blue arrows, respectively. A normal AC joint measures 1-3 mm whereas a normal CC distance measures 11-13 mm.1 The injury was classified as a Rockwood type III AC joint separation. Discussion: The AC joint is a synovial joint between an oval facet on the acromion and a similar facet on the distal end of the clavicle. Horizontal stability is provided by the AC joint while axial stability is provided by the CC joint.2,3 AC joint injuries account for about 9%-12% of shoulder girdle injuries, and the most common mechanism is direct trauma.4,5 Initial evaluation with imaging includes plain films with three views: the anterior-posterior (AP view with the shoulder in internal and external rotation as well as an axillary, or scapula-Y view (sensitivity 40%, specificity 90% for all films.6,7 AC joint injuries are classified by the Rockwood system.8 Type I involves a sprain or incomplete tear of the AC ligaments with an intact CC ligament. The AC joint appears normal on X-ray, but can become widened with stress, achieved by having the patient hold a 10-15 pound weight from each

    2009-01-01

    The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) is an international convention, under the auspices of the International Atomic Energy Agency (IAEA). It is a companion to a suite of international conventions on nuclear safety and physical security, which serve to promote a global culture for the safe use of radioactive materials. The Joint Convention is an official international treaty, and as such, there are obligations on the part of the United States. Those nations having ratified the Joint Convention are designated as 'Contracting Parties.' Nations that are not IAEA Member States may also become Contracting Parties to the Joint Convention, although none has done so. The primary obligations are threefold. The first is to prepare a national report, which addresses the national safety program in radioactive waste management, spent nuclear fuel management, and disused sealed sources. As the U.S. prepares a national report, other Contracting Parties to the Joint Convention also prepare their national reports, which leads to the second obligation on the part of the Contracting Parties. This is the obligation to review other countries' national reports. The last specific obligation is to actively participate in the triennial peer review meeting, referred to as the Review Meeting of the Contracting Parties. The U.S. ratified the Joint Convention in 2003, just prior to the First Review Meeting of the Contracting Parties, and has participated fully therein in the ensuing Review Meetings. Because of the benefits in active participation, it is important for the U.S. to maintain its leadership role in promoting its ratification in the global setting, as well as in more focused regions. Because of the important benefits associated with active participation, the U.S. has strongly supported a Regional Conference Initiative outreach program to increase membership. To launch the Initiative, the U

    Finley, David T.; Smith, Byron; DeGroff, B.

    2012-09-01

    Finding a contract vehicle that balances the concerns of the customer and the contractor in a development project can be difficult. The customer wants a low price and an early delivery, with as few surprises as possible as the project progresses. The contractor wants sufficient cost and schedule to cover risk. Both want to clearly define what each party will provide. Many program offices do not want to award cost plus contracts because their funding sources will not allow it, their boards do not want an open ended commitment, and they feel like they lose financial control of the project. A fixed price incentive contract, with a mutually agreed upon target cost, provides the owner with visibility into the project and input into the execution of the project, encourages both parties to save costs, and stimulates a collaborative atmosphere by aligning the respective interests of customers and contractors.

  13. Claims in civil engineering contracts

    CERN Document Server

    Speirs, N A

    1999-01-01

    This paper considers claims arising during civil engineering construction contracts. The meaning of the word 'claim' is considered and its possible implications for additional cost and time to completion. The conditions of the construction contract selected will influence the risk apportionment between contractor and client and the price offered by the contractor for the work. Competitive bidding constraints and profit margins in the construction industry, however, may also influence the price offered. This in turn can influence the likelihood of claims arising. The client from his point of view is concerned to complete the work within an agreed time and budget. The circumstances under which claims may arise are reviewed in relation to typical conditions of contract. These circumstances are then related to the CERN LHC civil works. Ways of avoiding claims, where this is possible, are considered. Finally, the means of evaluation of claims and their settlement are considered.

  17. The Contracting Parties' Ability To Conclude The Employment Contract

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available This study's main objective is to analyze certain effects produced by the changes of the Labor Code and by the entry into force of the current Romanian Civil Code. These effects refer to one of the fundamental conditions for the valid conclusion of the individual employment contract, that is, to the legal capacity of employers and employees. Thus, a complete analysis of legal regulations and of the correlations between different provisions on the legal capacity of parties to the individual employment contract is required to identify the existing noncompliance and to propose solutions. The research demonstrated that the current regulatory framework governing the legal capacity of the parties to an individual employment contract does not entirely correspond to the social reality. Therefore, only the employer benefits from a relatively comprehensive statutory regulation on the legal capacity to conclude an individual employment contract. The employee, however, does not benefit from the same attention from legislature. Considering the above, the study represents a significant scientific contribution, whose value lies in the proposed changes to modify legislature, so that the legal capacity of job holders would benefit from fair regulation, in accordance with the principle of legal protection of employee rights.

  20. Debt renegotiation with incomplete contract

    Directory of Open Access Journals (Sweden)

    Paulo de Melo Jorge Neto

    2005-09-01

    Full Text Available A debt contract usually does not include a provision about renegotiation. The right to seize the borrower’s asset and the rules of this process are usually stipulated in the contract. Such a promise not to renegotiate is not credible since renegotiation can mitigate the dead-weight loss of liquidating insolvent borrowers. Once the initial contract may not consider the renegotiation procedure and renegotiation may occur, this paper investigates why a complete contract is not offered. It shows that the lender does not need to stipulate the renegotiation procedure on the initial contract because he is indifferent about committing or not to the terms of a contract. This indicates that a complete contract gives the lender the same expected return as an incomplete contract, in which the renegotiation process is determined after the occurrence of default.Um contrato de débito geralmente não inclui uma cláusula sobre renegociação. O direito de liquidar os ativos do tomador e as regras do processo são habitualmente estipuladas no contrato. Tal promessa de não renegociar não é crível, já que a renegociação pode mitigar a perda bruta de se liquidar tomadores insolventes. Uma vez que o contrato inicial pode não considerar os procedimentos de renegociação, e esta pode, de fato, vir a ocorrer, este artigo investiga a razão de um contrato completo não ser ofertado. Mostra-se que o emprestador não precisa estipular os procedimentos de renegociação no contrato inicial porque ele é indiferente entre se comprometer ou não aos termos do contrato. Isto indica que um contrato completo dá ao emprestador o mesmo retorno esperado de um contrato incompleto, no qual os procedimentos de renegociação são determinados após a declaração de default.

    It is the purpose of the study to demonstrate the clinical relevance of degenerative changes in the facet joint of patients with low back pain irradiating to the lower extremities, and discuss some problems relating to diagnosis and different diagnosis. 119 patients presenting the listed bellow syndromes are covered by the study: scoliosis, polytopic pain vertebral syndrome, paresis and history of trauma. all patients undergo comprehensive neurological examination with special attention focused on the spine: CT and plain x-rays are taken of the lumbosacral segment to assess the condition of the facet joints. The neurological examination demonstrates in all cases pain syndrome in the lumbar spine referred to one or both lower extremities. In 56% it is a matter of persisting pain, and in 44% - recurrent. More than half of the patients complain of sacroiliac (SI) dislocation and palpatory pain. Unilateral or bilateral degenerative changes are documented by imaging studies in all patients, including: subchondral thickening, osteopathy narrowing the lateral or central part of the spinal canal with ensuing nerve root compression. The lumbosacral zygoapophyseal joints are source of pseudoradicular pain. A correlation between clinical picture and GT changes is noted in all patients with facet joint syndrome. CT is an indispensable method in diagnosing facet joint syndrome. (authors)

  4. Temporomandibular joint examination reviewed

    Directory of Open Access Journals (Sweden)

    L. Guarda Nardini

    2011-09-01

    Full Text Available The temporo-mandibular joint (TMJ it’s a joint closely related to the skull base, the spine, and the jaws; all these anatomical structures must be taken in consideration when evaluating pain involving the tmj. In order to detect patients affected by pathology or dysfunctions of the tmj, physical examination is of great value in orienting the diagnosis. Inspection must consider the symmetry of the body, the dental status and the type of occlusion. Palpation is a way to assess contractiont involving the muscles of the masticatory system and of the neck. Auscultation, based on articular noise provides means to determine whether we are dealing with degeneration of the joint or a dislocation of the intrarticular disc. In order to confirm the diagnosis obtained with the clinical evaluation, it’s useful to perform imaging techniques as opt, tomography and TC of the tmj and electromyokineosiography – index of the mandibular functionality and of the muscles status. MRI and dynamic MRI are among the non invasive exams which give the greatest amount of information, regarding the disc position and the joint degeneration. Arthroscopy is an invasive technique that allows early diagnosis of degeneration and is helpful to reveal early inflammatory processes of the joint.

  5. Distal radioulnar joint injuries

    Directory of Open Access Journals (Sweden)

    Binu P Thomas

    2012-01-01

    Full Text Available Distal radioulnar joint is a trochoid joint relatively new in evolution. Along with proximal radioulnar joint , forearm bones and interosseous membrane, it allows pronosupination and load transmission across the wrist. Injuries around distal radioulnar joint are not uncommon, and are usually associated with distal radius fractures,fractures of the ulnar styloid and with the eponymous Galeazzi or Essex_Lopresti fractures. The injury can be purely involving the soft tissue especially the triangular fibrocartilage or the radioulnar ligaments.The patients usually present with ulnar sided wrist pain, features of instability, or restriction of rotation. Difficulty in carrying loads in the hand is a major constraint for these patients. Thorough clinical examination to localize point of tenderness and appropriate provocative tests help in diagnosis. Radiology and MRI are extremely useful, while arthroscopy is the gold standard for evaluation. The treatment protocols are continuously evolving and range from conservative, arthroscopic to open surgical methods. Isolated dislocation are uncommon. Basal fractures of the ulnar styloid tend to make the joint unstable and may require operative intervention. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Prosthetic replacement in arthritis is gaining acceptance in the management of arthritis.

  6. Formation of Exfoliation Joints

    Science.gov (United States)

    Martel, S. J.

    2004-12-01

    The Earth's internal stresses interact with the topographic surface to affect many phenomena. Exfoliation joints, or sheeting joints, are widespread manifestations of this interaction. These opening-mode fractures form subparallel to the Earth's surface, bounding roughly concentric slabs of rock that resemble the layers of an onion. They occur worldwide in all major bedrock types, attain in-plane dimensions of hundreds of meters, exert a strong influence on groundwater flow, and help produce spectacular scenery, as in Yosemite National Park. The mechanism that causes them has been enigmatic. They are widely regarded as forming in response to "removal of overburden", but large fractures do not open in rocks merely by relieving a compressive stress. High fluid pressures, thermal effects, rock heterogeneity, and weathering also are rejected as primary causes of these fractures. Tensile stresses normal to the surface are required for large exfoliation fractures to open. Intriguingly, high surface-parallel compressive stresses are widely documented where exfoliation joints occur. Both numerical and analytical solutions for two-dimensional elastic bodies show that localized tensile stresses perpendicular to the ground surface must develop beneath certain topographies subject to strong compressive stresses parallel to the surface. This highly non-intuitive effect reflects the profound influence that topography can have on stresses near the surface of the Earth, and it can explain how exfoliation joints open. The theoretical results also indicate that exfoliation joint distributions could be used to infer the horizontal stresses near the Earth's surface.

  7. The temporomandibular joint

    International Nuclear Information System (INIS)

    Campbell, W.

    1984-01-01

    Whilst the temporomandibular joint is in many ways unique, it is subject to all the diseases and disorders found in joints in other parts of the human skeleton. By far the most common disorder is injury, followed by arthropathy, acute and chronic dislocations, ankylosis, and in rare instances, neoplasms. The diagnosis and management of the temporomandibular joint are the primary responsibility of the oral surgeon. Nevertheless, this anatomical region is an area in which the cooperation of medical and dental disciplines may be required for the satisfactory conclusion of treatment. The more so when the disease process involves either associated psychosomatic illness or malignancy. The mainstay of the diagnosis is a careful radiological examination of the joint. There exists a delicate relationship between the dentition, the muscles of mastication, and the temporomandibular articulation, which is controlled by arthrokinetic reflex activity of the branches of the 5th cranial nerve. Imbalance between one or more of the components of this integrated system frequently leads to disturbances in function. Pain-dysfunction disorders constitute the larger part of temporomandibular joint disturbances generally encountered

    To investigate the effect of delayed skin grafting combined traction in severe joint cicatricial contracture. At the first stage, the joint cicatricial contracture was released completely with protection of vessels, nerves and tendons. The wound was covered with allogenetic skin or biomaterials. After skin traction for 7-14 days, the joint could reach the extension position. Then the skin graft was performed on the wound. 25 cases were treated from Mar. 2000 to May. 2013. Primary healing was achieved at the second stage in all the cases. The skin graft had a satisfactory color and elasticity. Joint function was normal. All the patients were followed up for 3 months to 11 years with no hypertrophic scar and contraction relapse, except for one case who didn' t have enough active exercise on shoulder joint. Delayed skin grafting combined traction can effectively increase the skin graft survival rate and improve the joint function recovery.

  9. Total ankle joint replacement.

    Science.gov (United States)

    2016-02-01

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

  10. Coordinating Contracts for Two-Stage Fashion Supply Chain with Risk-Averse Retailer and Price-Dependent Demand

    Directory of Open Access Journals (Sweden)

    Minli Xu

    2013-01-01

    Full Text Available When the demand is sensitive to retail price, revenue sharing contract and two-part tariff contract have been shown to be able to coordinate supply chains with risk neutral agents. We extend the previous studies to consider a risk-averse retailer in a two-echelon fashion supply chain. Based on the classic mean-variance approach in finance, the issue of channel coordination in a fashion supply chain with risk-averse retailer and price-dependent demand is investigated. We propose both single contracts and joint contracts to achieve supply chain coordination. We find that the coordinating revenue sharing contract and two-part tariff contract in the supply chain with risk neutral agents are still useful to coordinate the supply chain taking into account the degree of risk aversion of fashion retailer, whereas a more complex sales rebate and penalty (SRP contract fails to do so. When using combined contracts to coordinate the supply chain, we demonstrate that only revenue sharing with two-part tariff contract can coordinate the fashion supply chain. The optimal conditions for contract parameters to achieve channel coordination are determined. Numerical analysis is presented to supplement the results and more insights are gained.

    [Purpose] The aim of this study was to examine the immediate effects of muscle strength training and neuromuscular joint facilitation distal resistance training on wrist joints by using electromechanical reaction time. [Subjects and Methods] The subjects were 12 healthy young people (24.2 ± 3.1 years, 169.7 ± 6.5 cm, 65.3 ± 12.6 kg). Two kinds of isotonic contraction techniques were applied on the wrist joint: the wrist joint extension muscle strength training and the wrist joint extension pattern of neuromuscular joint facilitation. The electromechanical reaction time, premotor time, and motor time of the left upper limb were measured before and after each intervention session of muscle strength training and neuromuscular joint facilitation. [Results] The neuromuscular joint facilitation group showed significant shortening of the electromechanical reaction time and motor time after the intervention. [Conclusion] These results suggest that the electromechanical reaction time and motor time of the wrist joint can be improved by neuromuscular joint facilitation together with proximal resistance training, which can be used as a new form of exercise for improving the functions of subdominant hand wrist joints.

    Full Text Available Joint involvement in syphilis has been considered as casuistry in recent years. At the same time, the high incidence of primary syphilis and the notified cases of late neurosyphilis may suggest that joint involvement in this disease is by no means always verified. Traditionally there are two forms of syphilitic arthritis: primary synovial (involving the articular membranes and sac and primary bone (involving the articular bones and cartilages ones. The paper describes the authors' clinical case of the primary bone form of articular syphilis in a 34-year-old man.

    This discourse recounts efforts put into the SNR-2 project; specifically the development of compensation devices. The various prototypes of these compensation devices are described and the state of the development reviewed. Large Na (sodium)-heat transfer systems require a lot of valuable space if the component lay-out does not include compensation devices. So, in order to condense the spatial requirement as much as possible, expansion joints must be integrated into the pipe system. There are two basic types to suit the purpose: axial expansion joints and angular expansion joints. The expansion joints were developed on the basis of specific design criteria whereby differentiation is made between expansion joints of small and large nominal diameter. Expansion joints for installation in the sodium-filled primary piping are equipped with safety bellows in addition to the actual working bellows. Expansion joints must be designed and mounted in a manner to completely withstand seismic forces. The design must exclude any damage to the bellows during intermittent operations, that is, when sodium is drained the bellows' folds must be completely empty; otherwise residual solidified sodium could destroy the bellows when restarting. The expansion joints must be engineered on the basis of the following design data for the secondary system of the SNR project: working pressure: 16 bar; failure mode pressure: 5 events; failure mode: 5 sec., 28.5 bar, 520 deg. C; working temperature: 520 deg. C; temperature transients: 30 deg. C/sec.; service life: 200,000 h; number of load cycles: 10 4 ; material: 1.4948 or 1.4919; layer thickness of folds: 0.5 mm; angular deflection (DN 800): +3 deg. C or; axial expansion absorption (DN 600): ±80 mm; calculation: ASME class. The bellows' development work is not handled within this scope. The bellows are supplied by leading manufacturers, and warrant highest quality. Multiple bellows were selected on the basis of maximum elasticity - a property

    Sacroiliac joint (SIJ) pain is an important cause of lower back problems. Multiple SIJ injection techniques have been proposed over the years to help in the diagnosis and treatment of this condition. However, the SIJ innervation is complex and variable, and truly intra-articular injections are sometimes difficult to obtain. Different sacroiliac joint injections have shown to provide pain relief in patients suffering this ailment. Various techniques for intraarticular injections, sacral branch blocks and radiofrequency ablation, both fluoroscopy guided and ultrasound guided are discussed in this paper. Less common techniques like prolotherapy, platelet rich plasma injections and botulism toxin injections are also discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    SUMMARY Prosthetic joint infection (PJI) is a tremendous burden for individual patients as well as the global health care industry. While a small minority of joint arthroplasties will become infected, appropriate recognition and management are critical to preserve or restore adequate function and prevent excess morbidity. In this review, we describe the reported risk factors for and clinical manifestations of PJI. We discuss the pathogenesis of PJI and the numerous microorganisms that can cause this devastating infection. The recently proposed consensus definitions of PJI and approaches to accurate diagnosis are reviewed in detail. An overview of the treatment and prevention of this challenging condition is provided.

    Objective: To analyze the MRI characters of Charcot joint, and to evaluate the diagnostic value of X-ray, CT, and MRI on Charcot joint. Methods: Eight patients with 8 Charcot joints underwent X-ray, CT, and MR examinations. 6 of them had syringomyelia, 1 patient had injury of the spinal cord, and 1 case had diabetes. All 8 patients had sensory reduction or deficit in the sick extremities. Results: There were two types of Charcot joint, hypertrophic and atrophic. Radiographic and CT features of hypertrophic joint (n=3) showed hyperostotic osteosclerosis and mammoth osteophytes in the sick bones, periarticular ossification, and articular disorganization. Radiographic and CT features of atrophic joint (n=5) showed extensive bone resorption (destruction), periarticular debris, and articular disorganization. Main MRI features of Charcot joint included hydrarthrosis within joint capsule, thickened, loose, and elongated joint capsule with para-joint, peri-diaphysis, and inter-muscular extension in a pseudopodia pattern. The irregular joint capsule wall was presented as mild hypointensity on T 1 WI, slight hyper-intensity on T 2 WI, and was markedly enhanced after Gd-DTPA was administrated, which was considered as a characteristic manifestation of the lesion. Soft tissue mass containing hypo-intense stripes on both T 1 WI and T 2 WI was commonly noted adjacent to the involved joint. Conclusion: X-rays plain film is the first choice for the diagnosis of Charcot joint, and MRI is pretty useful in the diagnosis of Charcot joint

    This quantitative research study assesses the organizational characteristics, market factors, and profitability of US hospitals that operate joint ventures with other health care organizations. Data was obtained from the 2001 American Hospital Association annual survey, the Area Resource File, and the Center for Medicare and Medicaid Services Minimum Data Set. These data files provide essential information on individual acute care hospitals, the communities they serve, and the level of financial performance. Descriptive statistics were evaluated and a logistic regression model was utilized to examine hospitals operating joint ventures. The study found hospitals that operate joint ventures are located in communities with more elderly patients, lower unemployment, and lower HMO penetration. From an operating performance perspective, hospitals that operate joint ventures have a higher occupancy rate, a higher average length of stay, more clinical services, lower long-term debt, and a greater number of managed care contracts. The results also appear to indicate that joint ventures have a positive financial impact on US hospitals. The study has managerial implications supporting the use of joint ventures to improve hospital performance and policy implications on resource allocation.

    Neuromuscular electrical stimulation (NMES) that stimulates skeletal muscles to induce contractions has been widely applied to restore functions of paralyzed muscles. However, the architectural changes of stimulated muscles induced by NMES are still not well understood. The present study applies sonomyography (SMG) to evaluate muscle architecture under NMES-induced and voluntary movements. The quadriceps muscles of seven healthy subjects were tested for eight cycles during an extension exercise of the knee joint with/without NMES, and SMG and the knee joint angle were recorded during the process of knee extension. A least squares support vector machine (LS-SVM) LS-SVM model was developed and trained using the data sets of six cycles collected under NMES, while the remaining data was used to test. Muscle thickness changes were extracted from ultrasound images and compared between NMES-induced and voluntary contractions, and LS-SVM was used to model a relationship between dynamical knee joint angles and SMG signals. Muscle thickness showed to be significantly correlated with joint angle in NMES-induced contractions, and a significant negative correlation was observed between Vastus intermedius (VI) thickness and rectus femoris (RF) thickness. In addition, there was a significant difference between voluntary and NMES-induced contractions . The LS-SVM model based on RF thickness and knee joint angle provided superior performance compared with the model based on VI thickness and knee joint angle or total thickness and knee joint angle. This suggests that a strong relation exists between the RF thickness and knee joint angle. These results provided direct evidence for the potential application of RF thickness in optimizing NMES system as well as measuring muscle state under NMES.

    Women have higher rates of knee ligament injury than men. Co-contraction of knee muscles is proposed to be an important mechanism to protect the joint from injuries. Females have lower co-contraction levels when compared to males. Exploratory, cross-sectional design. Thirty-six men and women equally divided into four groups according to gender and activity level (sedentary and athletic) were compared in relation to vastus lateralis and biceps femoris co-contraction before heel strike during level walking and before floor contact during landing from a jump. Muscular co-contraction was assessed by surface electromyography. Correlations between co-contraction and ligament laxity, extensor and flexor work, and flexion/extension torque ratio were also analyzed. No differences between genders were found in the studied situations (p0.381). During walking, co-contraction was greater in sedentary women compared to athletic women (p=0.002). A moderate inverse correlation was found between co-contraction during walking and women extensor (r=-0.613; p=0.007) and flexor (r=-0.575; p=0.012) work. During landing from a jump, no variables correlated to co-contraction in any of the groups tested (r0.477; p0.061). Co-contraction levels were not different between genders. Results suggest that women compensate strength deficits by means of increasing activation levels, possibly to generate adequate joint stiffness to meet stabilization demands. However, this is not evident in a more stressful activity like landing from a jump. This study contributes to a better understanding of the factors related to joint protection in females, who are at a greater risk of ligament injuries.

    Objective To investigate associations between running speeds and contraction times in 8- to 13-year-old children. Method This longitudinal study analyzed tensiomyographic measurements of vastus lateralis and biceps femoris muscles' contraction times and maximum running speeds in 107 children (53 boys, 54 girls). Data were evaluated using multiple correspondence analysis. Results A gender difference existed between the vastus lateralis contraction times and running speeds. The running speed was less dependent on vastus lateralis contraction times in boys than in girls. Analysis of biceps femoris contraction times and running speeds revealed that running speeds of boys were much more structurally associated with contraction times than those of girls, for whom the association seemed chaotic. Conclusion Joint category plots showed that contraction times of biceps femoris were associated much more closely with running speed than those of the vastus lateralis muscle. These results provide insight into a new dimension of children's development.

    2018-01-01

    Full Text Available Summary:. Infection of the temporomandibular joint (TMJ is a rare pediatric condition resulting from the introduction of pathogens into the joint by hematogenous seeding, local extension, or trauma. Early recognition of the typical signs and symptoms including fever, trismus, preauricular swelling, and TMJ region tenderness are critical in order to initiate further evaluation and prevent feared complications of fibrosis, ankylosis, abnormal facial structure, or persistence of symptoms. Contrast-enhanced computed tomography with ancillary laboratory analysis including erythrocyte sedimentation rate, C-reactive protein, and white blood cell count are beneficial in confirming the suspected diagnosis and monitoring response to therapy. Initial intervention should include empiric parenteral antibiotics, early mandibular mobilization, and joint decompression to provide synovial fluid for analysis including cultures. This report describes a case of TMJ bacterial arthritis in a healthy 6-year-old male who was promptly treated nonsurgically with intravenous antibiotics and localized needle joint decompression with return to normal function after completion of oral antibiotics and physical therapy.

    [Purpose] The purpose of this study was to examine immediate effects of strength training and NJF distal resistance training in wrist joints by using writing time and evaluation of proprioception using the JPE test. [Subjects and Methods] The subjects were 12 young healthy people (24.2 ± 3.1 y, 169.7 ± 6.5 cm, 65.3 ± 12.6 kg). Two isotonic contraction techniques were applied on the wrist joint: wrist joint extension muscle strength training (MST) and the wrist joint extension pattern of NJF. The uppercase English alphabet writing time and joint position errors of the left upper limb were measured before and after one intervention session of MST and NJF. [Results] The decrease in errors in wrist extension angle repetition and the writing time represented the improvement resulting from NJF. [Conclusion] This result suggests that the subdominant hands wrist joint proprioception and writing function can be improved by NJF together with proximal resistance training.

  1. An analysis of a joint shear model for jointed media with orthogonal joint sets

    Koteras, J.R.

    1991-10-01

    This report describes a joint shear model used in conjunction with a computational model for jointed media with orthogonal joint sets. The joint shear model allows nonlinear behavior for both joint sets. Because nonlinear behavior is allowed for both joint sets, a great many cases must be considered to fully describe the joint shear behavior of the jointed medium. An extensive set of equations is required to describe the joint shear stress and slip displacements that can occur for all the various cases. This report examines possible methods for simplifying this set of equations so that the model can be implemented efficiently form a computational standpoint. The shear model must be examined carefully to obtain a computationally efficient implementation that does not lead to numerical problems. The application to fractures in rock is discussed. 5 refs., 4 figs

    2015-12-01

    In an effort to improve mobility and alleviate pain from degenerative and connective tissue joint disease, an increasing number of individuals are undergoing prosthetic joint replacement in the United States. Joint replacement is a highly effective intervention, resulting in improved quality of life and increased independence [1]. By 2030, it is predicted that approximately 4 million total hip and knee arthroplasties will be performed yearly in the United States [2]. One of the major complications associated with this procedure is prosthetic joint infection (PJI), occurring at a rate of 1-2% [3-7]. In 2011, the Musculoskeletal Infectious Society created a unifying definition for prosthetic joint infection [8]. The following year, the Infectious Disease Society of America published practice guidelines that focused on the diagnosis and management of PJI. These guidelines focused on the management of commonly encountered organisms associated with PJI, including staphylococci, streptococci and select aerobic Gram-negative bacteria. However, with the exception of Propionibacterium acnes, management of other anaerobic organisms was not addressed in these guidelines [1]. Although making up approximately 3-6% of PJI [9,10], anaerobic microorganisms cause devastating complications, and similar to the more common organisms associated with PJI, these bacteria also result in significant morbidity, poor outcomes and increased health-care costs. Data on diagnosis and management of anaerobic PJI is mostly derived from case reports, along with a few cohort studies [3]. There is a paucity of published data outlining factors associated with risks, diagnosis and management of anaerobic PJI. We therefore reviewed available literature on anaerobic PJI by systematically searching the PubMed database, and collected data from secondary searches to determine information on pathogenesis, demographic data, clinical features, diagnosis and management. We focused our search on five commonly

  5. Venture financing of start-ups: A model of contract between VC fund and entrepreneur

    Directory of Open Access Journals (Sweden)

    Osintsev Yury

    2010-01-01

    Full Text Available Venture capital has become one of the main sources of innovation in the modern, global economy. It is not just a substitute for bank loans: it has proven to be a more efficient way of financing projects at different stages. On one hand, venture financing allows for projects with higher risk, which leads to the possibility of higher returns on investment. On the other hand, venture investors who usually have managerial experience often participate in governing the business, which certainly adds value to the enterprise. In this paper we establish the model of contract between the venture capital fund and the entrepreneur, focusing on probably the most important issue of this contract: the shares of the parties in the business. The shares in the company determine the distribution of the joint surplus. The expected joint profits are not just exogenously specified in the contract but are dependent on the behavioral variables of both parties at the stage of fulfilling the contract. We call the behavioral variable of the entrepreneur ‘effort’ and the one of the venture fund ‘advice’. The probability of the project’s success, and hence the expected joint revenues, are increased by these two. However, both kinds of effort are costly to the respective parties that have made them. Based on this fact we can elaborate the profit functions of both sides of the contract. Our model can be considered as a basis for specifying contracts concerning venture financing. It can provide the logic for how the equilibrium shares of entrepreneur and venture fund are obtained.

  6. Effects of Botulinum Toxin on Reducing the Co-contraction of Antagonists in Birth Brachial Plexus Palsy

    2014-01-01

    Birth brachial plexus palsy (BBPP) is usually caused by plexus traction during difficult delivery. Although the possibility of complete recovery is relatively high, 5% to 25% of BBPP cases result in prolonged and persistent disability. In particular, muscle imbalance and co-contraction around the shoulder and elbow cause abnormal motor performance, osseous deformities, and joint contracture. Physical and occupational therapies have most commonly been used, but these conventional therapeutic strategies have often been inadequate, in managing the residual muscle imbalance and muscle co-contraction. Therefore, we attempted to improve the functional movements, by using botulinum toxin type A, to reduce the abnormal co-contraction of the antagonist muscles. PMID:24639937

    The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) is an international convention, under the auspices of the International Atomic Energy Agency (IAEA). It is a companion to a suite of international conventions on nuclear safety and physical security, which serve to promote a global culture for the safe use of radioactive materials. Although the U.S. was the first nation to sign the Joint Convention on September 29, 1997, the ratification process was a challenging experience for the U.S., in the face of legislative priorities dominated by concerns for national security and threats from terrorism after September 11, 2001. Notwithstanding these prevailing circumstances, the U.S. ratified the Joint Convention in 2003, just prior to the First Review Meeting of the Contracting Parties, and participated fully therein. For the United States, participation as a Contracting Party provides many benefits. These range from working with other Parties to harmonize international approaches to achieve strong and effective nuclear safety programs on a global scale, to stimulating initiatives to improve safety systems within our own domestic programs, to learning about technical innovations by other Parties that can be useful to U.S. licensees, utilities, and industry in managing safety and its associated costs in our waste management activities. The Joint Convention process also provides opportunities to identify future areas of bilateral and multilateral technical and regulatory cooperation with other Parties, as well as an opportunity for U.S. vendors and suppliers to broaden their market to include foreign clients for safety improvement equipment and services. The Joint Convention is consistent with U.S. foreign policy considerations to support, as a priority, the strengthening of the worldwide safety culture in the use of nuclear energy. Because of its many benefits, we believe it is important to take

  1. Energy service contracting in DOD

    International Nuclear Information System (INIS)

    Dahle, D.E.

    1993-01-01

    The U.S. Department of Defense (DOD) annually consumes about $3 Billion in energy to operate facilities at military installations worldwide, representing about 80% of utility operating expense for all Federal facilities. Recent legislation and a Presidential Executive Order have directed DOD by Fiscal Year 2000 to reduce facility energy consumption by 20%, from the level of energy used in Fiscal Year 1985. To achieve this goal it is estimated that energy efficiency improvement investments between $2-3 billion would be required. Considering the competition for resources within DOD as it experiences downsizing and restructuring, DOD will need to seek opportunities to tap alternative investment strategies through energy service contracting to leverage Federal resources. Shared Energy Savings and Operations and Maintenance Energy Services contracting activities in the Department of the Navy will be used to address how such acquisition methods can contribute to achieving DOD energy efficiency goals

    International Nuclear Information System (INIS)

    Palmer-Huggins, D.

    1998-01-01

    Members of the New York Mercantile Exchange (NYMEX) include bankers, industry (such as refiners, producers, and electricity marketers) brokerage houses, and individuals. NYMEX is the largest physical commodity futures exchange in the world. The primary economic role of the commodity exchange industry was discussed, with special emphasis on open interest, volume, and liquidity. Hedge dynamics were also reviewed. A hedge was described as a financial instrument used to lock in prices, costs, and profit margins. Futures contracts in general, and electricity futures contracts in particular were defined ('a firm commitment to deliver or to receive a specified quantity or grade of commodity at a specific location within a designated month'). Results expected from hedging, - cost control, predictable margins, securing a certain market share, price stabilization - , the nature of options trading, and its benefits were also reviewed. 1 tab., 4 figs

    Classical reasons for carrying inventory include fixed (nonlinear) production or procurement costs, lead times, nonstationary or uncertain supply/demand, and capacity constraints. The last decade has seen active research in supply chain coordination focusing on the role of incentive contracts to achieve first-best levels of inventory. An extensive literature in industrial organization that studies incentives for vertical controls largely ignores the effect of inventories. Does the ability to ...

  10. Custom, contract, and kidney exchange.

    Science.gov (United States)

    Healy, Kieran; Krawiec, Kimberly D

    2012-01-01

    In this Essay, we examine a case in which the organizational and logistical demands of a novel form of organ exchange (the nonsimultaneous, extended, altruistic donor (NEAD) chain) do not map cleanly onto standard cultural schemas for either market or gift exchange, resulting in sociological ambiguity and legal uncertainty. In some ways, a NEAD chain resembles a form of generalized exchange, an ancient and widespread instance of the norm of reciprocity that can be thought of simply as the obligation to “pay it forward” rather than the obligation to reciprocate directly with the original giver. At the same time, a NEAD chain resembles a string of promises and commitments to deliver something in exchange for some valuable consideration--that is, a series of contracts. Neither of these salient "social imaginaries" of exchange--gift giving or formal contract--perfectly meets the practical demands of the NEAD system. As a result, neither contract nor generalized exchange drives the practice of NEAD chains. Rather, the majority of actual exchanges still resemble a simpler form of exchange: direct, simultaneous exchange between parties with no time delay or opportunity to back out. If NEAD chains are to reach their full promise for large-scale, nonsimultaneous organ transfer, legal uncertainties and sociological ambiguities must be finessed, both in the practices of the coordinating agencies and in the minds of NEAD-chain participants. This might happen either through the further elaboration of gift-like language and practices, or through a creative use of the cultural form and motivational vocabulary, but not necessarily the legal and institutional machinery, of contract.

    OpenAIRE

    Pirrong, Craig

    2001-01-01

    Replacement of delivery settlement of futures contracts with cash settlement is frequently proposed to reduce the frequency of market manipulation. This article shows that it is always possible to design a delivery-settled futures contract that is less susceptible to cornering by a large long than any given cash-settled contract. Such a contract is more susceptible to manipulation by large shorts, however. Therefore, cash settlement does not uniformly dominate delivery settlement as a means o...

    This paper introduces profitability uncertainty into an infinite-horizon variation of the classic Holmstrom and Milgrom (1987) model, and studies optimal dynamic contracting with endogenous learning. The agent's potential belief manipulation leads to the hidden information problem, which makes incentive provisions intertemporally linked in the optimal contract. We reduce the contracting problem into a dynamic programming problem with one state variable, and characterize the optimal contract w...

    This paper extends the idea of callable forward contracts, which are potentially useful as demand-side (interruptible-load) contracts, to their supply-side analogues. Together, these contracts allow market participants to take advantage of flexibility in generation or consumption to obtain a monetary benefit, while simultaneously removing the risk of market price fluctuations. This paper also considers the effects of strategic behavior on the part of market participants in their contract sales/purchase decisions

    Working paper GATE 2010-35; The recognition that contracts have a time dimension has given rise to a very abundant literature since the end of the 1980s. In such a dynamic context, the contract may take place over several periods and develop repeated interactions. Then, the principal topics of the analysis are commitment, reputation, memory and the renegotiation of the contract. Few papers have tried to apply the predictions of dynamic contract theory to data. The examples of applications int...

  18. Determination of Parachute Joint Factors using Seam and Joint Testing

    Science.gov (United States)

    Mollmann, Catherine

    2015-01-01

    This paper details the methodology for determining the joint factor for all parachute components. This method has been successfully implemented on the Capsule Parachute Assembly System (CPAS) for the NASA Orion crew module for use in determining the margin of safety for each component under peak loads. Also discussed are concepts behind the joint factor and what drives the loss of material strength at joints. The joint factor is defined as a "loss in joint strength...relative to the basic material strength" that occurs when "textiles are connected to each other or to metals." During the CPAS engineering development phase, a conservative joint factor of 0.80 was assumed for each parachute component. In order to refine this factor and eliminate excess conservatism, a seam and joint testing program was implemented as part of the structural validation. This method split each of the parachute structural joints into discrete tensile tests designed to duplicate the loading of each joint. Breaking strength data collected from destructive pull testing was then used to calculate the joint factor in the form of an efficiency. Joint efficiency is the percentage of the base material strength that remains after degradation due to sewing or interaction with other components; it is used interchangeably with joint factor in this paper. Parachute materials vary in type-mainly cord, tape, webbing, and cloth -which require different test fixtures and joint sample construction methods. This paper defines guidelines for designing and testing samples based on materials and test goals. Using the test methodology and analysis approach detailed in this paper, the minimum joint factor for each parachute component can be formulated. The joint factors can then be used to calculate the design factor and margin of safety for that component, a critical part of the design verification process.

    In this final report, we discuss both theoretical and applied research resulting from our DOE project, ICEKAP 2004: A Collaborative Joint Geophysical Imaging Project at Krafla and IDDP. The abstract below begins with a general discussion of the problem we addressed: the location and characterization of “blind” geothermal resources using microearthquake and magnetotelluric measurements. The abstract then describes the scientific results and their application to the Krafla geothermal area in Iceland. The text following this abstract presents the full discussion of this work, in the form of the PhD thesis of Stephen A. Onacha. The work presented here was awarded the “Best Geophysics Paper” at the 2005 Geothermal Resources Council meeting, Reno. This study presents the modeling of buried fault zones using microearthquake and electrical resistivity data based on the assumptions that fluid-filled fractures cause electrical and seismic anisotropy and polarization. In this study, joint imaging of electrical and seismic data is used to characterize the fracture porosity of the fracture zones. P-wave velocity models are generated from resistivity data and used in locating microearthquakes. Fracture porosity controls fluid circulation in the hydrothermal systems and the intersections of fracture zones close to the heat source form important upwelling zones for hydrothermal fluids. High fracture porosity sites occur along fault terminations, fault-intersection areas and fault traces. Hydrothermal fault zone imaging using resistivity and microearthquake data combines high-resolution multi-station seismic and electromagnetic data to locate rock fractures and the likely presence fluids in high temperature hydrothermal systems. The depths and locations of structural features and fracture porosity common in both the MT and MEQ data is incorporated into a joint imaging scheme to constrain resistivity, seismic velocities, and locations of fracture systems.

  19. The Operation of the Joint Protocol: Theoretical and Practical Implications Revisited

    International Nuclear Information System (INIS)

    Horbach, N.

    2008-01-01

    On 21 September 1988, a Joint Protocol Relating to the Application of the Vienna Convention and the Paris Convention was adopted and entered into force on 27 April 1992. The 1988 Joint Protocol (Article II) provides for a mutual extension of the operator's liability under the Paris and Vienna systems: thus, if a nuclear incident occurs for which an operator is liable under both the Vienna Convention and the Joint Protocol, he shall be liable in accordance with the Vienna Convention for nuclear damage suffered not only in the territory of Parties thereto, but also in the territory of Parties to both the Paris Convention and the Joint Protocol; conversely, if an incident occurs for which an operator is liable under both the Paris Convention and the Joint Protocol, there shall be reciprocity. Moreover, the Joint Protocol (Article III) eliminates conflicts of law which might otherwise arise, especially in transport cases, from simultaneous application of the two Conventions. Although the text of the Joint Protocol is quite straightforward, it still has led to different interpretations in legal doctrine concerning Article IV. The main concern is the conflict that might arise in respect of the appropriate designation of the competent court and applicable law in situations were courts of different states might claim exclusive jurisdiction. This depends also on whether the Joint Protocol should be interpreted as eliminating the distinction between Contracting Parties and non-Contracting Parties in respect of the 'functional' relations among Paris and Vienna Contracting Parties, also party to the Joint Protocol, as far as the operative provisions of both Conventions listed in Article IV are concerned (including the provisions on jurisdictional competence).

    Full Text Available Osteoarthritis, a degenerative joint disease, is the most commonrheumatic disorder mainly in a geriatric population. Manifestationsare pain, stiffness and functional loss in the affected joint.According to etiology it is classifi ed as primary (or idiopathicand secondary. Some risk factors for disease development aregenetics, race, age, sex, obesity, occupational activities andarticular biomechanics. Pathogenesis is the same for any cause orlocalization, being catabolic alterations, with synthesis, inhibitionand reparing intent of the cartilage matrix. Metalloproteinases andcytokines (IL-1,IL-6,TNF-α actions promote infl ammatory reactionand cartilage degradation. Pain, the most important symptom,does not correlate with radiologic fi ndings. Peripheral osteoarthritisoccurs predominantly in the knee, hip and hand. Diagnosis is basedon clinical features, laboratorial tests and radiological changes.Rheumatological associations’ guidelines for treatment includenon-pharmacologic (education, physiotherapy, assistive devices,and pharmacologic (analgesics, anti-infl ammatory drugs therapyand surgery. Arthroplasty seems to work better than medicines, butshould be used if other treatments have failed.

  10. Formation of tough composite joints

    International Nuclear Information System (INIS)

    Brun, M.K.

    1997-05-01

    Joints which exhibit tough fracture behavior were formed in a composite with a Si/SiC matrix reinforced with Textron SCS-6 fibers with either boron nitride or silicon nitride fiber coatings. In composites with BN coatings fibers were aligned uniaxially, while composites with Si 3 N 4 -coated fibers had a 0/90 degree architecture. Lapped joints (joints with overlapping fingers) were necessary to obtain tough behavior. Geometrical requirements necessary to avoid brittle joint failure have been proposed. Joints with a simple overlap geometry (only a few fingers) would have to be very long in order to prevent brittle failure. Typical failure in these joints is caused by a crack propagating along the interfaces between the joint fingers. Joints of the same overall length, but with geometry changed to be symmetric about the joint centerline and with an extra shear surface exhibited tough fractures accompanied with extensive fiber pullout. The initial matrix cracking of these joints was relatively low because cracks propagated easily through the ends of the fingers. Joints with an optimized stepped sawtooth geometry produced composite-like failures with the stress/strain curves containing an elastic region followed by a region of rising stress with an increase of strain. Increasing the fiber/matrix interfacial strength from 9 to 25 MPa, by changing the fiber coating, increased matrix cracking and ultimate strength of the composite significantly. The best joints had matrix cracking stress and ultimate strength of 138 and 240 MPa, respectively. Joint failure was preceded by multiple matrix cracking in the entire composite. The high strength of the joints will permit building of structures containing joints with only a minor reduction of design stresses

  13. Muscle activity during leg strengthening exercise using free weights and elastic resistance: effects of ballistic vs controlled contractions.

    Jakobsen, Markus Due; Sundstrup, Emil; Andersen, Christoffer H; Aagaard, Per; Andersen, Lars L

    2013-02-01

    The present study's aim was to evaluate muscle activity during leg exercises using elastic vs. isoinertial resistance at different exertion and loading levels, respectively. Twenty-four women and eighteen men aged 26-67 years volunteered to participate in the experiment. Electromyographic (EMG) activity was recorded in nine muscles during a standardized forward lunge movement performed with dumbbells and elastic bands during (1) ballistic vs. controlled exertion, and (2) at low, medium and high loads (33%, 66% and 100% of 10 RM, respectively). The recorded EMG signals were normalized to MVC EMG. Knee joint angle was measured using electronic inclinometers. The following results were obtained. Loading intensity affected EMG amplitude in the order: lowBallistic contractions always produced greater EMG activity than slow controlled contractions, and for most muscles ballistic contractions with medium load showed similar EMG amplitude as controlled contractions with high load. At flexed knee joint positions with elastic resistance, quadriceps and gluteus EMG amplitude during medium-load ballistic contractions exceeded that recorded during high-load controlled contractions. Quadriceps and gluteus EMG amplitude increased at flexed knee positions. In contrast, hamstrings EMG amplitude remained constant throughout ROM during dumbbell lunge, but increased at more extended knee joint positions during lunges using elastic resistance. Based on these results, it can be concluded that lunges performed using medium-load ballistic muscle contractions may induce similar or even higher leg muscle activity than lunges using high-load slow-speed contractions. Consequently, lunges using elastic resistance appear to be equally effective in inducing high leg muscle activity as traditional lunges using isoinertial resistance. Copyright © 2012 Elsevier B.V.

  14. Quality management and quality assurance contracts

    International Nuclear Information System (INIS)

    Teichler, M.

    1991-01-01

    Quality assurance contracts belong to the most important instruments of quality management systems. As a result of such contracts, quality control is to be done not only by the buyer, but is made a task to be fulfilled by the manufacturer. The author of the article shows that quality assurance contracts do change the contractual relationship between supplier and buyer, but have no effect on economic and practical conditions. This is so because quality assurance contracts apply only to warranty claims, which play a subordinate role in the legal relationship between producer and buyer, or producer and consumer, as compared to the claims for damages arising out of the contracts.

    1994-05-01

    A laboratory characterization of the Apache Leap tuff joints under cyclic pseudostatic and dynamic loads has been undertaken to obtain a better understanding of dynamic joint shear behavior and to generate a complete data set that can be used for validation of existing rock-joint models. Study has indicated that available methods for determining joint roughness coefficient (JRC) significantly underestimate the roughness coefficient of the Apache Leap tuff joints, that will lead to an underestimation of the joint shear strength. The results of the direct shear tests have indicated that both under cyclic pseudostatic and dynamic loadings the joint resistance upon reverse shearing is smaller than that of forward shearing and the joint dilation resulting from forward shearing recovers during reverse shearing. Within the range of variation of shearing velocity used in these tests, the shearing velocity effect on rock-joint behavior seems to be minor, and no noticeable effect on the peak joint shear strength and the joint shear strength for the reverse shearing is observed

  3. On the Dogmatics of Contract Interpretation

    Institute of Scientific and Technical Information of China (English)

    Yang Guoqing

    2017-01-01

    The interpretation of contract has attracted much attention in the practice of contract law and the basic problems to be solved are what the parties agree on and how to set up the rules of adjudication. The present domestic studies are not conducive to contract prac-tices because they either unnecessarily elevate scientific problems to the speculative realm of fantasy, or make the problems become more unreal and abstract. The two traditional theories of contract interpretation do not conflict in values in terms of the autonomy of the will and trust protection. However, in today' s society where cultural pluralism and legal value plural-ism exist, because of different contract practices, differentiation and individualization of con-tract interpretation will become the basic patterns. Therefore, it is impossible and unnecessary to construct a unitary model, but it is of great significance to introduce the dogmatics-orien-ted contract interpretation.

    This paper shall outline the content, application and management strategies for the various contracts related to transport and handling activities. In total, the two sections Logistics and Handling Maintenance are in charge of 27 (!) contracts ranging from small supply contracts to big industrial support contracts. The activities as well as the contracts can generally be divided into four main topics "Vehicle Fleet Management"; "Supply, Installation and Commissioning of Lifting and Hoisting Equipment"; "Equipment Maintenance" and "Industrial Support for Transport and Handling". Each activity and contract requires different approaches and permanent adaptation to the often changing CERN's requirements. In particular, the management and the difficulties experienced with the contracts E072 "Maintenance of lifting and hoisting equipment", F420 "Supply of seven overhead traveling cranes for LHC" and S090/S103 "Industrial support for transport and handling" will be explained in detail.

Catering contract (Housing and Bed and Board Contract is unnamed in our country and the main source of law for this contract are business practices and usage. A lot of attention is paid to this question. Lack of legal norms for this area is general characteristic for most of the tourism contracts. In this contract its title is also debatable because term 'catering services' is not usually used in practice. Although this contract is unnamed in Comparative Law ,in tourist more developed countries there are more codified business practices from this area and there is more Case Law. Having in mind development of tourist economy adequate legal conditions in tourism contract are expected.

    1984-01-01

    We reinvestigated the prevailing concept that muscle contractions only elicit increased muscle glucose uptake in the presence of a so-called "permissive" concentration of insulin (Berger et al., Biochem. J. 146: 231-238, 1975; Vranic and Berger, Diabetes 28: 147-163, 1979). Hindquarters from rats...... in severe ketoacidosis were perfused with a perfusate containing insulin antiserum. After 60 min perfusion, electrical stimulation increased glucose uptake of the contracting muscles fivefold. Also, subsequent contractions increased glucose uptake in hindquarters from nondiabetic rats perfused for 1.5 h......-methylglucose uptake increased during contractions and glucose uptake was negative at rest and zero during contractions. An increase in muscle transport and uptake of glucose during contractions does not require the presence of insulin. Furthermore, glucose transport in contracting muscle may only increase if glycogen...

    2009-01-01

    We propose a generic framework to obtain certain types of contracted and centrally extended algebras. This is based on the existence of quadratic algebras (reflection algebras and twisted Yangians), naturally arising in the context of boundary integrable models. A quite old misconception regarding the 'expansion' of the E 2 algebra into sl 2 is resolved using the representation theory of the aforementioned quadratic algebras. We also obtain centrally extended algebras associated with rational and trigonometric (q-deformed) R-matrices that are solutions of the Yang-Baxter equation.

  10. Muscle fatigue and contraction intensity modulates the complexity of surface electromyography.

    Science.gov (United States)

    Cashaback, Joshua G A; Cluff, Tyler; Potvin, Jim R

    2013-02-01

    Nonlinear dynamical techniques offer a powerful approach for the investigation of physiological time series. Multiscale entropy analyses have shown that pathological and aging systems are less complex than healthy systems and this finding has been attributed to degraded physiological control processes. A similar phenomenon may arise during fatiguing muscle contractions where surface electromyography signals undergo temporal and spectral changes that arise from the impaired regulation of muscle force production. Here we examine the affect of fatigue and contraction intensity on the short and long-term complexity of biceps brachii surface electromyography. To investigate, we used an isometric muscle fatigue protocol (parsed into three windows) and three contraction intensities (% of maximal elbow joint moment: 40%, 70% and 100%). We found that fatigue reduced the short-term complexity of biceps brachii activity during the last third of the fatiguing contraction. We also found that the complexity of surface electromyography is dependent on contraction intensity. Our results show that multiscale entropy is sensitive to muscle fatigue and contraction intensity and we argue it is imperative that both factors be considered when evaluating the complexity of surface electromyography signals. Our data contribute to a converging body of evidence showing that multiscale entropy can quantify subtle information content in physiological time series. Copyright © 2012 Elsevier Ltd.

    This study examined the acute effects of whole-body vibration (WBV) on knee joint position sense and indices of neuromuscular function, specifically strength, electromechanical delay and the rate of force development. Electromyography and electrically evoked contractions were used to investigate neural and contractile responses to WBV. Fourteen healthy males completed two treatment conditions on separate occasions: (1) 5 × 1 min of unilateral isometric squat exercise on a synchronous vibrating platform [30 Hz, 4 mm peak-to-peak amplitude] (WBV) and (2) a control condition (CON) of the same exercise without WBV. Knee joint position sense (joint angle replication task) and quadriceps neuromuscular function were assessed pre-, immediately-post and 1 h post-exercise. During maximum voluntary knee extensions, the peak force (PF(V)), electromechanical delay (EMD(V)), rate of force development (RFD(V)) and EMG of the quadriceps were measured. Twitch contractions of the knee extensors were electrically evoked to assess EMD(E) and RFD(E). The results showed no influence of WBV on knee joint position, EMD(V), PF(V) and RFD(V) during the initial 50, 100 or 150 ms of contraction. Similarly, electrically evoked neuromuscular function and neural activation remained unchanged following the vibration exercise. A single session of unilateral WBV did not influence any indices of thigh muscle neuromuscular performance or knee joint proprioception. © 2011 John Wiley & Sons A/S.

  12. Mechanical influences on morphogenesis of the knee joint revealed through morphological, molecular and computational analysis of immobilised embryos.

    Full Text Available Very little is known about the regulation of morphogenesis in synovial joints. Mechanical forces generated from muscle contractions are required for normal development of several aspects of normal skeletogenesis. Here we show that biophysical stimuli generated by muscle contractions impact multiple events during chick knee joint morphogenesis influencing differential growth of the skeletal rudiment epiphyses and patterning of the emerging tissues in the joint interzone. Immobilisation of chick embryos was achieved through treatment with the neuromuscular blocking agent Decamethonium Bromide. The effects on development of the knee joint were examined using a combination of computational modelling to predict alterations in biophysical stimuli, detailed morphometric analysis of 3D digital representations, cell proliferation assays and in situ hybridisation to examine the expression of a selected panel of genes known to regulate joint development. This work revealed the precise changes to shape, particularly in the distal femur, that occur in an altered mechanical environment, corresponding to predicted changes in the spatial and dynamic patterns of mechanical stimuli and region specific changes in cell proliferation rates. In addition, we show altered patterning of the emerging tissues of the joint interzone with the loss of clearly defined and organised cell territories revealed by loss of characteristic interzone gene expression and abnormal expression of cartilage markers. This work shows that local dynamic patterns of biophysical stimuli generated from muscle contractions in the embryo act as a source of positional information guiding patterning and morphogenesis of the developing knee joint.

  14. Geomechanical Response of Jointed Caprock During CO2 Geological Sequestration

    Geological sequestration of CO2 refers to the injection of supercritical CO2 into deep reservoirs trapped beneath a low-permeability caprock formation. Maintaining caprock integrity during the injection process is the most important factor for a successful injection. In this work we evaluate the potential for jointed caprock during injection scenarios using coupled three-dimensional multiphase flow and geomechanics modeling. Evaluation of jointed/fractured caprock systems is of particular concern to CO2 sequestration because creation or reactivation of joints (mechanical damage) can lead to enhanced pathways for leakage. In this work, we use an equivalent continuum approach to account for the joints within the caprock. Joint's aperture and non-linear stiffness of the caprock will be updated dynamically based on the effective normal stress. Effective permeability field will be updated based on the joints' aperture creating an anisotropic permeability field throughout the caprock. This feature would add another coupling between the solid and fluid in addition to basic Terzaghi's effective stress concept. In this study, we evaluate the impact of the joint's orientation and geometry of caprock and reservoir layers on geomechanical response of the CO2 geological systems.

    This paper evaluates MR imaging with the therapeutic effect after splint therapy in internal derangement of the temporomandibular joint (TMJ). Fifteen patients (19 TMJs) with internal derangement of the TMJ and five normal volunteers (10 TMJs) were examined with sagittal T1-weighted spin-echo and gradient recalled acquisition in a steady state (GRASS) MR imaging. MR studies of the patients undergoing splint therapy were performed with an without splints. Pseudodynamic images of TMJ motion provide information that was not available from spin-echo T1-weighted images
