Comparative Study of Geometry of Receiver of Solar Parabolic Trough Concentrator

Parabolic trough collectors are widely used as a solar energy recovery device, with the reflected concentrated solar energy focused mostly to a single cylindrical tube. In present study, the parabolic Trough of Aperture 1.2 m and length 3.6 m was fabricated using mild steel and its interior surface covered with reflective surface of ionized aluminium with a reflectivity of 84 %. The system is equipped with a receiver made of bare copper tube positioned at the focal line. The working fluid is water. The research focuses on the temperature variations achieved from changes in the geometry of the receiver. In this experiment the outlet temperature of two receivers of different geometry are compared (stepped and uniform tube). The results are plotted in a tabular format and a graph shows the variation in performance due to the change in geometry. The outlet steam temperature obtained in stepped tube was higher as compared to the uniform tube. The percentage increase in outlet steam temperature in stepped tube as compared to uniform tube was on an average 5.41% during the time of 11:00 am to 4:00 pm.
Studies Show : Medicaid Patients Have Worse Access and Outcomes than the Privately Insured

■ ■ Medicaid is a prime example of government’s inability to outperform—or even keep up with—the private sector. Policymakers should reform Medicaid to allow Medicaid patients access to private insurance in a consumerdriven market. Abstract Academic literature has consistently illustrated that Medicaid patients— adults and children—have inferior access to health care, and notably poorer health outcomes, than privately insured patients. Due to the program’s low reimbursement rates, more and more doctors are refusing to even accept Medicaid. As a result, it is becoming increasingly difficult for Medicaid patients to find access to primary and specialty care physicians. When Medicaid patients are admitted to hospitals, they are often admitted with more serious conditions than those with private insurance. By further expanding this broken program, Obamacare will only exacerbate the situation, continuing to harm many low-income Americans who have no option other than Medicaid. Policymakers should reform Medicaid to allow Medicaid patients access to private insurance in a consumer-driven market. E as a fundamental component of President Lyndon Johnson’s Great Society, Medicaid is a jointly funded federal and state program that pays for health care for low-income individuals. The academic literature has consistently illustrated that Medicaid patients have poorer access to care, and poorer health outcomes, than privately insured patients. By further expanding this broken program, the Patient Protection and Affordable Care Act—Obamacare—only exacerbates the situation. Policymakers should reform Medicaid to provide consumers with greater access to private insurance in a consumer-driven market. Medicaid typically pays physicians 56 percent of the amount that private insurers pay.1 Given these low reimbursement rates, more and more doctors are refusing to accept Medicaid.2 As a result, it is becoming increasingly difficult for Medicaid patients to find primary care doctors and specialists. When Medicaid patients are admitted to hospitals, they are often admitted with more serious conditions, and in some cases, with a higher level of co-morbidity, than privately insured patients.

PHOSPHOLIPIDS AS VERSATILE POLYMER IN DRUG DELIVERY SYSTEMS

Phospholipids become more and more important as pharmaceutical excipients. This review article summarizes meticulous features of phospholipids and their application in various drug delivery systems and elucidates numerous techniques to improve the bioavailability and disposition of drugs administered through various routes. The advantages of phospholipid based drug delivery systems not only enhance the bioavailability of drugs with poor aqueous solubility, membrane penetration, and also enhancement or alteration of uptake and release of drugs, protection of sensitive drugs from degradation in the gastrointestinal tract, reduction of gastrointestinal side effects and even masking of bitter taste of orally administered drugs. Various formulation strategies to achieve these effects are highly diverse and offer various possibilities of liquid, semi-solid and solid lipid-based formulations for drug delivery optimization such as liposomes, lipospheres, lipid nanoparticles, micelles, nanoemulsions, solid dispersion etc.,
EURECOM at TRECVID 2017: The Adhoc Video Search

—This paper describes the submissions of the EURECOM team to the TRECVID 2017 AVS task. Our approach is to project both the text topic and the visual keyframes in the same vector space, corresponding to a word embedding. We compare and combine several word embeddings, also using specific keyword weightings.
Effect of an Early Nutritional Supplement on Broiler Performance

Chicks are commonly held for up to 72 h from the time of actual hatch to placement under commercial industry practices. Delaying access to feed and water has been documented to increase susceptibility to pathogens and weight loss, leading to poorly starting flocks with reduced weight gains. Seven experiments were conducted to compare the use of EarlyBirdTM (EB; Sigrah-Zellet, LLC.) to no supplementation (NS) in chick boxes when chicks were held for a 24 h simulated shipping period. In each experiment, broilers were obtained from a commercial hatchery, neck tagged, individually weighed and randomly placed in boxes of 100 chicks. Treated chicks received 2 g/chick of EB. Following 24 h, chicks were individually weighed and placed with feed and water ad libitum. In all experiments, chicks that received EB during simulated shipping experienced significantly less body weight loss during the 24 holding period (p<0.05) and were significantly heavier at 7 d. At slaughter, EB treated broilers were 58 g heavier than the controls. The results are consistent with earlier reports indicating that the dependence of chicks on residual yolk sac during the first few days post hatch limits the growth potential of modern broilers. Early feeding can not only impact the general well being of the chick but also can have significant effects on early growth, leading to increased weight gains that persist through broiler production.
A compressive sensing-based approach for Preisach hysteresis model identification

The Preisach hysteresis model has been adopted extensively in magnetic and smart material-based systems. Fidelity of the model hinges on accurate identification of the Preisach density function. Existing work on the identification of the density function usually involves applying an input that provides sufficient excitation and measuring a large set of output data. In this paper, we propose a novel compressive sensing-based approach for Preisach model identification that requires fewer measurements. The proposed approach adopts the discrete cosine transform of the output data to obtain a sparse vector, where the order of all the output data is assumed to be known. The model parameters can be efficiently reconstructed using the proposed scheme. For comparison purposes, a constrained least-squares scheme using the same number of measurements is also considered. The root-mean-square error is adopted to examine the model identification performance. The proposed identification approach is shown to have better performance than the least-squares scheme through both simulation and experiments involving a vanadium dioxide ( VO 2 )-integrated microactuator.
Flowering of Avocado (Persea americana Mill.) As Influenced by Gibberellic Acid Treatments

Summary The effect of gibberellic acid (GA3) treatments on the reproductive development of 'Hass' avocado trees was investigated at macroscopic and microscopic level. GA3 (50 or 250 mg/L) was applied to three-year-old trees as single or multiple foliar sprays. On untreated trees, bud swelling was observed in early autumn (April) and flowering occurred four to five months later in late winter/spring (August/September). However, at microscopic level, secondary inflorescence axis meristems were already present in buds of untreated trees in late summer (early March). Single GA3, treatments applied in late summer (March) had no significant effect on flower development, but multiple GA3, treatments applied from late summer through early winter (March-May) inhibited flower development for one season.
The Nontradability Premium of Derivatives Contracts

We investigate nontradable and tradable identical Treasury derivatives. The nontradability premium is statistically and economically significant, and it covaries positively with interest rate volatility and relative tightness in the markets. Our data offer an almost-perfect laboratory to study the determinants of liquidity. The product of conditional interest rate volatility times the underlying bill's turnover is a better liquidity measure than the trading volume, amount outstanding, and turnover. A higher turnover is associated with a lower expected time for trading at a "desirable" price. The higher the volatility, the larger the marginal value of a reduction in the expected time to trade.
Ionization enhanced diffusion

The diffusion equation and diffusion coefficient parametrization are established for the normal ionization‐enhanced diffusion mechanism and the Bourgoin mechanism. These mechanisms can facilitate the diffusion of impurities and defects in semiconductors and insulators. The Bourgoin mechanism is athermal, i.e., it does not require thermal activation.
Investigation of Parallel Manipulators Using Linear Complex Approximation

This investigation deals with singularity analysis of parallel manipulators and their instantaneous behavior while in or close to a singular configuration. The method presented utilizes line geometry tools and screw theory to describe a manipulator in a given position. Then, this description is used to obtain the closest linear complex, presented by its screw coordinates, to the set of governing lines of the manipulator. The linear complex axis and pitch provide additional information and a better physical understanding of the type of singularity and the motion the manipulator tends to perform in a singular point and in its neighborhood. Examples of Hunt's, Fichter's and 3-UPU singularities, along with a few selected examples taken from Merlet's work [1], are presented and analyzed using this method.
Plasma: Pursuit of Dentistry

Plasma, fourth state of matter where as others exist in liquid, solid and gas. Plasma, a collection of stripped particles. Plasma is stripped electrons from atoms and molecules by changing their state. As stripping electrons takes constant energy which makes plasma naturally energetic. Plasma particle become gas, If the energy dissipates and the electrons reattach. Thus, plasma consists of positively and negatively charged ions and negatively charged electrons as well as radicals, neutral and excited atoms and molecules. [1, 2].
A Sex Difference in Seasonal Timing of Birth in a Livebearing Fish

Abstract Sex differences in seasonal timing include differences in hatch- or birth-date distribution and differences in the timing of migration or maturation such as protandrous arrival timing (PAT), which is early male arrival at breeding sites. I describe a novel form of protandrous arrival timing, as a sex difference in birth-date distribution in a live-bearing fish (Dwarf Perch, Micrometrus minimus). In this species, birth coincides with arrival at breeding sites because newborn males are sexually active. A series of samples of pregnant females and young of year was collected in Tomales Bay, CA. I analyzed the daily age record in otoliths to estimate the conception date of broods and the age that young-of-year individuals were born. Males were born at a younger age than females, as indicated by the daily age record and also by the predominance of females in broods from which some young had already been born, which was a common occurrence in pregnant females with older embryos. Sex ratio of broods varied with conception date such that early-season broods were predominantly male, possibly as a result of temperature-dependent sex determination. The combined effects of the sex difference in age at birth and seasonal shift in sex ratio were to shift the mean birth date of males relative to females by five days. The most likely ultimate explanation for PAT in the Dwarf Perch is that it arises from exploitation (scramble) competition for mating opportunities among recently-born young-of-year males.
Localization with a Surface Operator, Irregular Conformal Blocks and Open Topological String

Following a recent paper by Alday and Tachikawa, we compute the instanton partition function in the presence of the surface operator by the localization formula on the moduli space. For SU(2) theories we find an exact agreement with CFT correlation functions with a degenerate operator insertion, which enables us to work out the decoupling limit of the superconformal theory with four flavors to asymptotically free theories at the level of differential equations for CFT correlation functions (irregular conformal blocks). We also argue that the K theory (or five dimensional) lift of these computations gives open topological string amplitudes on local Hirzebruch surface and its blow ups, which is regarded as a geometric engineering of the surface operator. By computing the amplitudes in both A and B models we collect convincing evidences of the agreement of the instanton partition function with surface operator and the partition function of open topological string.
A Review on Palmprint Recognition

: Biometrics is defined as the exceptional or individual physical properties or attributes of human body. These attributes are used to recognize each human. Any details of the person body which differs from another person to the other is used as unique biometrics data which serve to that’s person’s unique ID. Palmprint recognition being one of the important aspects of biometric technology. These palmprint recognition serves into four stages, palmprint image acquisition, preprocessing, feature extraction and matching. The major approach for palmprint recognition is to extract feature vector from each individual palm and to perform matching based on some distance metrics. This paper present a detailed review on palmprint recognition approaches.
Learning Disabilities in Children: Epidemiology, Risk Factors and Importance of Early Intervention

Children with learning disabilities have significant impairment in reading, writing and mathematics, in spite of normal intelligence and sensory abilities. In reading disability, children will have difficulties in phonemic sensitivity, phonetic decoding, word recognition, word decoding skills and reading comprehension. The lifetime prevalence of learning disability is about 10%. Learning disabilities are more frequently seen in boys compared to girls. There are several risk factors for learning disabilities. Low birth weight, preterm birth, neonatal complications, language delay and epilepsy are important risk factors for learning disabilities in children. Students with learning disabilities have poor scholastic performance, anxiety and significant stress. They have more social, emotional and behavioural problems than those without learning problems. If not remedied at the earliest, learning disabilities will lead to failure in exams and these children may develop stress related disorders. Hence all children with learning problems should be evaluated scientifically at the earliest, for identification of learning disability. By providing scientific guidance and intensive one to one remedial training, learning problems of children can be managed successfully.
HIGHLY ACCURATE INTEGRATION OF TRACK MOTIONS

According to the largeness of the workpieces in several industrial environments, a great number of industrial robots is placed on external track motions, so called 7 axes, as for automotive or aircraft industries. Flexible automation today requires absolute high accuracy. For example modern robotics deals with offline programming, copying programs between similar working cells, reflecting programs or image processing for 3D-pose estimation. All these tasks need absolute high accuracy and in fact, there have been many investigations for increasing the accuracy of single robots in the past few years. In contrast to that the use of track motions will dramatically increase the position error and badly influence the static behaviour of the robot system. The main reasons for these additional errors are the incorrect identification of the main track direction and furthermore, very crucial, the non-linearities of the TCP (Tool Center Point) during the robots motion on the track. This article will introduce a new method of identification and mathematical integration of linear tracks. At first we present the method for measuring and generating profiles of single tracks by making use of the discrete fourier transformation (DFT) and cubic spline interpolation. Then a method for recalculating offline generated programs for real environments is presented, followed by a method for copying programs taking two profiles of track motions into consideration. Finally some measurement results are shown.
Thermal degradation of Heterogeneous Concrete Materials

In this paper, we examine the interaction of thermal and mechanical damage processes in heterogeneous materials such as concrete. After a brief introduction of high temperature effects in concrete, we address two topics: (1) the interaction of thermal and mechanical damage at the mesomechanical level of observations, when volumetric and deviatoric degradation take place simultaneously; and (2) the effect of thermal expansion and shrinkage in the two-phase concrete material when thermal softening of the elastic properties leads to massive degradation of the load resistance.
Sleep-disordered breathing and self-reported general health status in Thai patients

Abstract Background: Sleep-disordered breathing (SDB) has been a rapidly increasing health problem in Thai. Its effect on quality of life of Thai patients has not been adequately addressed. Objective: Determine the relationship between SDB and self-reported general health status in Thai patients. Materials and methods: A descriptive and cross-sectional study was used. Two hundred and sixtyeight patients (195 men and 73 women, age: 16-82 years) are recruited from King Chulalongkorn Memorial Hospital between January 2006 and December 2007. A health profile was obtained by self-administered questionnaire. SDB severity was assessed using an attended single-night comprehensive polysomnography. Results: SDB was not directly associated with the general health status. Presence of excessive daytime sleepiness, which was the major symptom of obstructive sleep apnea, was associated with a decrease in all domains of Short Form 36. Age, sex, and body mass index were also related to a lower physical function. Hypertension and excessive daytime sleepiness were associated with the severity of SDB. Conclusion: SDB is indirectly related to a lower general health status, and this relationship is of clinical significance.
The meanings and purpose of employee voice

In this paper we present and assess an analytical framework for examining the different ‘meanings, purposes and practices’ of employee voice. The data were collected from eighteen organizations in England, Scotland and Ireland. Managers defined voice very much in terms of the perceived contribution to efficiency and tended to downplay notions of rights; however, the linkages between voice and performance outcomes remain problematic. Overall, employee voice is best understood as a complex and uneven set of meanings and purposes with a dialectic shaped by external regulation, on the one hand, and internal management choice, on the other. The evidence suggests that the degree to which voice practices are embedded in an organization is much more important than reporting the extent of any particular individual or collective schemes for employee voice.
Does Audit Quality in Libya Meet the International Standards Levels

This study provide empirical evidence of the current situation and measure the perceptions of the level of audit quality in Libya by focusing on oil companies. It aims to examine the extent to which Libyan Accountants and Auditors Association (LAAA) and audit firms and play an essential role in enhancing the quality of audit and developing the audit profession. A questionnaire and interviews were used to collect data from audit firm that works in Libya and Libyan oil companies. The study finds that there is a lack of professionalism among auditors in Libya is pervasive and that weaknesses in the current regulatory framework are detrimental and have led to the ineffectiveness of the LAAA. In addition, the ignorance of audit firms in Libya in respect of new services, and the inability of Libya’s education system to produce competent graduates, all contribute to the low level of audit quality that the profession.
Postpartum uterine infection and endometritis in dairy cattle

After parturition, uterine involution, regeneration of the endometrium, return of ovarian cyclic activity, and the control of pathogenic bacteria in the uterus is required before cows are likely to conceive again. However, pathogenic bacteria often cause uterine disease in modern dairy cattle, leading to decreased productivity and reduced fertility. This review aims to provide an overview of postpartum uterine infection and disease in dairy cattle. Metritis and endometritis are the main postpartum clinical conditions; although, subclinical endometritis is an emerging issue. Postpartum uterine disease is associated with the isolation of Escherichia coli, Trueperella pyogenes, and anaerobic pathogenic bacteria. Sensing of bacteria or their pathogen-associated molecules, such as lipopolysaccharide, by the innate immune system generates inflammatory responses. Endometrial inflammation includes increased expression of complement, calgranulins, interleukins and acute phase proteins, as well as the chemotaxis of neutrophils and macrophages to the site of infection. Uterine disease is also characterised by tissue damage, including endometrial cytolysis caused by the cholesteroldependent cytolysin, pyolysin. The responses to pathogens are energetically expensive, and depletion of the key cellular nutrients, glucose or glutamine, impairs inflammatory responses by endometrial tissues. For sustainable intensification of the dairy industry over the next 50 years, it is vital to understand why high-milkyield cows are so susceptible to uterine pathology and develop new ways to prevent uterine disease.
