Orogastric tube feeding is indicated in neonates with impaired ability to ingest food normally and can be administered by intermittent bolus (INT) or continuous (CON) infusion. Insulin and amino acids play important roles in the regulation of protein synthesis in the neonate. While the sensitivity to insulin is developmentally regulated (Davis et al., 1998) and greatly diminishes with age (Wray-Cahen et al., 1997), amino acids exert a positive effect on muscle protein synthesis throughout life (Denne et al., 1991; Davis et al., 1998; Volpi et al., 1998). In addition to providing amino acids to other organs when dietary supplies are insufficient, high rates of proteolysis are necessary to provide amino acids for ongoing tissue modeling and rapid growth. The two most important proteolytic pathways in skeletal muscle are thought to be the ubiquitin-proteasome and autophagy-lysosome systems (Ventadour and Attaix, 2006). The aim of this study was to determine if these feeding modalities affect growth and lean tissue accretion, and the mechanisms for this response.


Nanoparticle suspensions (NPSs) are suspensions of nanosize particles in base fluids in the form of a solid–liquid mixture. They are used extensively in a wide range of industrial and engineering applications, and show considerably different and tunable, physiochemical, thermal, and radiative properties compared to other solutions. It has been demonstrated that added nanoparticles can significantly alter and enhance the optical and radiative properties of the base fluids. There is still a concern about the particle agglomeration and sedimentation behaviors and the long-term stability of NPSs under different conditions, which may limit their potential reliable applications. There is a close relationship between the particle agglomeration and the optical and radiative properties of nanoparticle suspensions. In this review, the relationship between these fundamental properties with the emphasis on the procedural stability of nanoparticle suspensions is explored. Different issues related to the preparation and the characterization of NPSs, their sedimentation, the effects of particle types, sizes on individual, hybrid, and agglomerated nanoparticle suspensions, as well as the effect of pH values, are discussed. Their effects on the optical and spectral radiative properties are also discussed. Simplified analyses are outlined based on dependent–independent scattering demarcation and effective properties of NPSs.


The exhaustion of fossil fuel and the greenhouse gas emission are one of the most significant energy and environmental issues, respectively. Photovoltaic (PV) generators and battery energy storage systems (BESSs) have been significantly increased for recent years. The BESSs are mainly used for smoothing active power fluctuation of the PV. In this paper, PV–BESSs integration of two DC/DC converters and one AC/DC converter is investigated and DC-link voltage control to compensate the AC voltage deviation is proposed for the PV‒BESS system in low-voltage (LV) networks.


To obtain an exact solution of the radiative-transfer equation in media where both absorption and scattering are significant, the usual approach is to use a numerical method. Three methods are known in the literature: invariant imbedding, eigenvalue-eigenfunction, and matrix doubling. This paper examines the practical application of these methods to the problem of emission from an inhomogeneous (Rayleigh) layer, the effects of layer parameters on the stability. It is found that invariant imbedding is most suitable for computing emission from an inhomogeneous layer with a temperature profile but tends to be unstable as the optical thickness of the layer increases beyond 0.5. On the other hand, the matrix-doubling method is stable for arbitrary optical thickness but is not suitable for handling multilayers. The eigenvalue-eigenfunction method is more stable than the invariant imbedding as optical thickness increases up to 2.0. It also permits temperature profile in the layer, but the computation is much more complicated. It is less stable than the matrix-doubling method when optical thickness is larger than 2.0. In general, the choice of a method is dependent on the nature of the problem.


Professor Welford was invited by the late K. F. H. Murrell and the other prime movers who founded the Ergonomic Research Society (ERS (now the Ergonomics Society)) to join them as a foundation member. At the time he was a lecturer in experimental psychology and director of the Nuffield Unit for Research into Problems of Ageing at the Cambridge University Psychological Laboratory. He thus typified the alliance of academic and applied interests which the new found Society was to keep in close touch. He became the Chairman of its Council having the task of keeping the protagonists of these two interests from falling out, success in this endeavour leading to the flourishing Society to which we are heirs. He gave up the Chairmanship to become the first editor of this journal, and held this position until he went on a visit to Australia in 1964. There he was instrumental in inspiring the formation of the Ergonomics Society of Australia and New Zealand of which he was later to be President. In 1968 he was appoin...


On February 17th 2010, the GIZ, in collaboration with KfW, evaluated the possibility of establishing a REDD+ project within the confines or surrounding the MCNP. The pre-feasibility of establishing a REDD+ project in the area was carried out by GFA ENVEST in 2009. The aim of the study was to assess the feasibility a REDD+ project aiming at a reduction/avoidance of ongoing deforestation in the ecologically valuable Mt. Cameroon area. Deforestation would be avoided by the development and implementation of a REDD+ project, which would be connected to the newly established MCNP. The REDD+ project would finance both the administration of the National Park as well as compensation measures in the surrounding villages.


There are numerous techniques available to find occurrences of activities in time-stamped observation data with each occurrences having an associated probability.For the entire research community the activity recognition is considered to be a big challenge. The existing techniques cannot deal with "zero day" attacks that have never seen before .In the proposed system it is able to find the subsequenes of the observation data,called unexplained sequence,that known models are not able to "explain" with a certain confidence.Thus we have to consider a known set of activities which contains both innocuous and dangerous activities .We want to monitor and also we want to identify the unexplained subsequences in an observation sequence that are poorly explained that is,we want to identify the activities that are not present in this predefined set.Top-k algorithms are used to identify the top-k totally and partially unexplained activities.In the proposed system these algorithms are applied on the Cyber Security data sets. These algorithms are more efficient and provides faster search for identifying totally and partially unexplained sequences.


We examine the Higgs boson low-energy theorems and their applications in the study of light Higgs boson interactions with mesons and baryons. In particular, we clarify how a new parameter (the A parameter) emerges when the chiral Lagrangian method is combined with the Higgs low-energy theorems to obtain predictions for the interaction of Higgs bosons and pseudoscalar mesons. The computation of the Higgs–nucleon coupling and the branching ratios for light Higgs boson production in the decays K → πH and η′ → ηH are illustrated.


Abstract Aim and Background: Human sexual function is an essential component of life, and Female sexual dysfunction (FSD) adversely affects health, well-being quality of life. The combinations containing L-arginine theoretically lead to vasodilatation of genitalia in women and can, through this mechanism, increase sexual arousal. The goal of this study is to investigate the effects of topical L-arginine on female sexual function. Methods and Materials: This randomized clinical trial was performed on 76 women who were interested in improving their sexual function. They entered the study to apply either of two identical tubes of gel (one L-arginine gel and one placebo gel), to the clitoral hood prior to intercourse for four weeks. The subjects were randomly divided into two groups of experimental (n=38) and control (n=38). Sexual function in both groups before and four weeks after treatment was assessed by Female sexual Function Index Rosen (FSFI). Data were analyzed using SPSS Findings: The obtained results showed, in both groups, the score of total FSFI, and score of each domain including sexual desire, arousal, lubrication, orgasm, satisfaction and pain were significantly increased after intervention (p 0.05) Conclusions : Topical L-arginine and placebo equally improved female sexual function and showed no significant difference in two groups. Keywords: Female Sexual Function, L-arginine, Female Sexual Function Index (FSFI)


ABSTRACT The need for highly qualified bilingual and English as a Second Language (ESL) teachers continues to rapidly increase. In this article, we share the results of a multi-year study that has aimed to determine what factors affect the performance of teacher candidates seeking bilingual education and ESL in a teacher preparation program in the Southwest. In this article, we focus on 89 teacher candidates' performance on the Core Subject (TExES 291) test, as it represents one of the most important testing attempts these teacher candidates must pass in order to be on track toward certification. For this manuscript we explored both internal (e.g., gender, age group, ethnicity) as well as external factors (e.g., good test taker) to determine the extent to which these had a role (or otherwise) in their test performance. While our data confirm previous studies findings regarding the impact of internal factors such as gender, age, marital status, among others, teacher preparation can help mitigate some barriers for ESL and bilingual certification.

Fossilized portions of a charophyte found in close association with disperse gyrogonites identified
as Leonardosia langei Sommer are described. One sample has an antheridium apparently connected to
a thallus clearly corticated. Considering the close association and the lack of other carophyte species than
L. langei the thalli are thought to belong to this species. The male structure is very rare and is recorded for
the first time in L. langei and in the Porocharaceae. The samples consist of compressions/impressions from
the Corumbatai Formation (Guadalupian of the Parana Basin), found in the municipality of Piracicaba, in
the Brazilian state of Sao Paulo. The presence of such algae provides evidence of some of the palaeoenvironmental
conditions prevailing during the deposition of the Corumbatai Formation: a low energy environment,
probably along the margin of a shallow inland sea not directly connected to the ocean.


Objectives: Resistance exercise is an effective method for weight control programs, and it might be useful to understand its influence on acute body energy hemostasis changes.

During the Great Patriotic War, many newspapers and zhurnaly ceased publication, a substantial portion of reduced size and circulation. It happened in the central publishing houses, the Soviet Union, but most acutely felt these problems in publishing the union and autonomous republics. Many journalists went to the front, continuing to work on the front line soldiers in the trenches, to tell the Soviet people about what is happening in the midst of military events. In particular, at this time in the Bashkir Cavalry Division produced front-line newspaper "Bashkort atlylary" (editor Ali Karnay). In front newspapers intended for soldiers Tatars and Bashkirs, working M. Karim, G. Akhmetshin, A. Bikchentaev and other writers. From printing "October onslaught" went to the front more than 100 people. During the war years were published such works as "In the steppes of the Don" (1942), "From the bottom of my heart" (1943) Saifi Kudash; "Song of Love and Hate" (1942), "Kill my son, a fascist!" (1944) Rasit Nigmati; "Roads of War" (1944) Hanifa Karimov and many others. The staff of the printing is a great help scholars and writers brotherly Ukraine, located in the evacuation of Ufa, releasing their scientific works, collections and magazines. In 1944 the production of the national newspapers became an independent printing house, now SUE "Publisher of Bashkortostan." During the Great Patriotic War, the regional newspaper Meleuzovsky area "for the harvest," reflected the heroic labor of workers, farmers, all residents of the district has made an enormous contribution to the organization of assistance to the front. She was brought up by a sense of patriotism, instilling confidence in victory.

GPUs perform most efficiently when all threads in a warp execute the same sequence of instructions convergently. However, when threads in a warp encounter a divergent branch, the hardware serializes the execution of diverged paths. We consider a class of convergence opportunities wherein multiple threads are expected to eventually execute a given segment of code, but not all threads arrive at the same time, resulting in serialized duplicate execution of common code subsequences such as function calls and loop bodies. Our goal is to promote convergence by helping threads that execute common code arrive together before allowing execution to proceed. We propose a new user-guided compiler mechanism, Speculative Reconvergence, to help identify and exploit previously untapped convergence opportunities that increase SIMT efficiency and improve performance. For the set of workloads we study, we see improvements ranging from 10% to 3× in both SIMT efficiency and in performance.

episode in 2006 had both American and Chinese hosts discussing how polite and constructive criticism can help both China and America to do better. Their view was that each country should point out to the other, areas that need improvement. Then both countries should exhort each other to be a better country for their respective citizens while simultaneously improving the conditions for domestic business and international trade. Finally, having lived among Chinese people for the past many years, I can say that the politeness and patience that foreigners encounter in China have nothing to do with modern politics. Rather, these Chinese traits are embedded in Chinese history. I have learned over the years that there is no intended ethnocentrism among friends of different cultures and different nations. If we realized how much identical knowledge we share, few misunderstandings would occur. As one of my students in Hong Kong once wrote: 'there is no 3rd world, no 2nd world, or 1st world, just one World'. One example she gave was that much of what China exports to the USA is actually manufactured by American-owned companies. Against this background, these books written by American scholars offer valuable insights into how Sino-American trade and international relationships have reached their current state. Each book is written in a style, so accessible that any international business practitioner or researcher should be able to make informed judgements about how these relationships might develop in the future.


We utilized simultaneous coupling of higher and ground states of a single QD with two different resonant modes of a PhC nanocavity for efficient excitation and emission. Enhanced emission with strongly suppressed background was demonstrated.


Pilot contamination attack is an important kind of active eavesdropping activity conducted by a malicious user during channel training phase. In this paper, motivated by the fact that frequency asynchronism could introduce divergence of the transmitted pilot signals between intended user and attacker, we propose a new uncoordinated frequency shift (UFS) scheme for detection of pilot contamination attack in multiple antenna system. An attack detection algorithm is further developed based on source enumeration method. Both the asymptotic detection performance analysis and numerical results are provided to verify the proposed studies. The results demonstrate that the proposed UFS scheme can achieve comparable detection performance as the existing superimposed random sequence based scheme, without sacrifice of legitimate channel estimation performance.


(26) Of the various determinant forms thus far obtained the most promising is that of §8 or that of §14; and to these it is desirable now to return in order to obtain an expression for the eliminant in the ordinary non-determinant notation. In doing so it will also be well to make a slight change in the coefficients of the three quadrics, viz., to write f, g, h for 2f, 2g, 2h, as in this way the diversity in the cofactors of the determinants occurring in the last three rows of either form of the eliminant disappears.


Since the end of 2019, the outbreak of COVID-19 has had a severe impact on the economy and peoples lives. In this paper, Freshippo was selected as the research object to discuss the problems and optimization strategies of its supply chain in the context of the epidemic, to provide reference for supply chain management of fresh food e-commerce enterprises. The research methods used in this paper are literature review and field research. The epidemic has brought historic opportunities to the whole fresh food e-commerce industry represented by Freshippo, but also put forward higher requirements for the efficiency and flexibility of the supply chain. The fresh food e-commerce industry should optimize supply chain management for improving response efficiency and coping with epidemic risk, improve emergency support capacity, ensure freshness of goods and reduce wastage, and share supply chain costs.


An intelligent building energy system which has power grid, autonomous generators, renewable energy resources, storage devices, and controllable loads has been proposed. In this paper, we consider an allocation and scheduling problem of electrical and thermal storage devices together with other devices in building energy system to minimize the overall cost while satisfying the occupants demand. The above problem is formulated as a mixed integer programming problem. The CPLEX solver is used to solve the proposed problem. By the proposed method, we can fix the types of storage devices and allocate the capacity of the fixed storage devices with demand profiles and their investment cost. The performance analysis of storage devices is demonstrated using numerical cases.


ABSTRACT:A ground loop heat exchanger in a ground source heat pump system is an impor-tant unit that determines the thermal performance of a system and its initial cost. A proper design requires certain site specific parameters, most importantly the ground effective thermal conduc-tivity, the borehole thermal resistance and the undisturbed ground temperature. This study was performed to investigate the effect of some parameters such as borehole lengths, various grouting materials and U tube configurations on ground effective thermal conductivity and borehole thermal resistance. In this study, thermal response tests were conducted using a testing device to 9 different ground loop heat exchangers. From the experimental results, the length of ground loop heat exchanger affects to the effective thermal conductivity. The results of this experiment shows that higher thermal conductivity of grouting materials leads to the increase effective thermal conduc-tivity from 22 to 32%. Also, mounting spacers have increased by 14%.

The BMA has criticised politicians who are campaigning for the United Kingdom to leave the European Union for making false claims about NHS funding.

Mark Porter, the BMA's chair of council, condemned the claims in his keynote speech at the BMA's annual representatives meeting in Belfast on Monday 20 June. Although the BMA's position on the referendum to leave the EU is neutral, Porter said that the association could not remain neutral in condemning claims that the NHS would receive billions …


Integrated Curriculum and Pedagogical Practices in the Federal Institutes (Ifs): Mapping Researches in Databases
Abstract: This article focuses on the part of an investigation being carried out at the Universidade do Vale do Taquari. It aimed to map researches about curriculum and integrating pedagogical practices in the Federal Institutes of Education between 2014 and 2018, through qualitative approach and documentary analysis. Four sources for information collection were chosen: the Database with Theses and Dissertations of the Coordination for the Improvement of Higher Education Personnel (CAPES), CAPES Journal Portal, the Group of Study and Research on Work and Education (GEPTE) and a work released in the 1st National Seminar for the Integrated Secondary School, which presents research in the Federal Network, in distinct states of Brazil. The material analyzed allows us to conclude that a variety of practices may depict curriculum integration, in light of diverse theoretical perspectives, as well that numerous integrating alternatives were evidenced in various pedagogical experiments.

The simulation of a zero-offset (ZO) section from multi-coverage reflection data for 2-D media is a widely used seismic reflection imaging method that reduces the amount of data and enhances the signal-to-noise ratio. The aim of the CRS stack method is not only to improve the resulting stack section but also to determine parameters that are useful with respect to a subsequent inversion. The main advantage of the common reflection surface (CRS) stack is the use of analytical formulae that describe the kinematic reflection response of inhomogeneous media with curved interfaces but do not depend on a macro velocity model. For the travel time estimation the CRS stack uses circular wavefronts that are associated with the local dips and radii of curvatures of the reflectors. The result of this approach yields a stacking surface in the data set for each point in the simulated ZO section. These concepts are based on ideas of de Bazelaire (1986), de Bazelaire and Thore (1987), Gelchinsky (1988), Keydar et al. (1990) and Berkovitch et al. (1994). However, we give no review of their methods but use a different approach for the derivation of the formulae involved in the CRS stack. For constant velocity media we derive exact formulae for the CRS stack. In order to extend these formulae to inhomogeneous media we use attributes of hypothetical waves that would be observed at the surface (Hubral (1983)). The resulting formulae depend on these a priori unknown attributes, which can be determined by a search procedure involving coherency analysis (Taner and Koehler (1969)). Besides the stack section, one obtains a coherency section and various attribute sections. The coherency section is helpful to identify the locations of reflection events. There, one can subsequently use the attributes to derive the a priori unknown macro velocity model (Hubral and Krey (1980), Goldin (1986)). Taylor series expansions of the CRS surface provide explicit formulae. Additionally, these formulae allow to split the search procedure into separate steps in order to reduce the computational costs: e. g., the search of the required attributes can be first performed in the CMP gathers and afterwards in the resulting CMP stack section, a concept introduced by de Bazelaire and Thore (1987). 1email: email@example.com 7


The Jack-up rig has been utilized in the development of offshore oil for more than thirty years in China. A lot of Jack-up rig leg penetration analysis has been carried out and rich experiences have been accumulated. However, the predicted leg penetration results were inconsistent with those actual leg penetration results in some new oilfield development area. The main reasons lay in the insufficient understanding of soil properties, unsuitable soil parameters,simplicity of calculation model and the lackness of local experiences etc. To improve the accuracy of predicted penetration, the important considerations for jack-up rig leg penetration analysis were summarized through many engineering practices in this paper. The predicted results coincided with the actual results based on those considerations in an actual case.


Character recognition is capturing incremental interests due to the revoked interests in text recognition. Optical character recognition converts handwritten images into machine encoded text. For character recognition, feature extraction and its representation are important issues, which has been pursued in recent years. Principal Component Analysis Network (PCANet) is a very simple deep learning network for image classification designed by cascading PCA filters same as convolution filters in convolution neural network. PCANet uses very basic data processing components: cascaded principal component analysis (PCA), binary hashing and block wise histograms. In this paper, we apply gradient descent to learn the number of filters used in the various stages of PCANet. The proposed method achieves promising performance on the Modified National Institute of Standards and Technology database (MNIST) dataset and on the Devanagari handwritten character dataset (achieving an accuracy of 98.946% and 84.09% respectively), demonstrating the effectiveness of learning the number of convolution filters in PCANet using gradient descend in character recognition.


During the growing season of 2011,the leaves of four Bt transgenic clones B1,B4,B17 and B21 of Populus deltoides × P.euramericana cv.'Nanlin895' were exposed to the target pest larvae of Micromelalopha troglodyta to assess the insecticidal activity of Bt transgenic P.deltoides × P.euramericana cv.'Nanlin895' under laboratory and field conditions.It was showed that all the clones had certain insecticidal activity against target pests.The corrected mortality of the target pest feeding on clone B21 was as high as 95.3%.The corrected mortalities in August and September were 35.0%-88.8% and 40.5%-95.3% respectively under field conditions.The pupation ratio was 83.3%-96.0% in CK,while in transgenic poplar that was 8.0%-76.7%,showing a significant difference between them.The development of target larvae was inhibited by Bt transgenic P.deltoides × P.euramericana cv.'Nanlin895'.After 8 days' feeding,the intake and growth rate of target larvae were significantly lower than that of the CK.The effect of Bt transgenic poplars on microorganisms in rhizosphere soil was also studied and no significant difference was found in the quantities of bacteria,fungi,and actinomycete between the transgenic and non-transgenic poplars,suggesting no negative influence on the soil microorganism system.


A series of trials was conducted to investigate the effects of Conmar 80 (80% CP), a new commercial hexane-extracted fish meal, as a protein source in creep and weaner-starter diets. Eight dietary treatments, comparable in composition except for the protein source, were offered in three experiments to 112 litters and 44 Yorkshire piglets. The first two trials were designed to compare piglet performance, during the suckling and early-weaning period when Conmar 80 was included as part of the creep diet or the starter diet protein. The third trial was designed to study the digestibility of increasing levels of Conmar 80 as a protein source in the weaner ration of 70-d old barrows. The results of this study indicate that piglet performance was not adversely affected when Conmar 80 was substituted at 3.5–5.0% of the creep diet or when Conmar 80 was used as the sole animal protein source in the starter diet. The digestibility of dry matter and crude protein was 85.6 ± 0.05% and 85.1 ± 0.24%; 74.7 ± 0.14% and 73...

Libraries of the 21 st century are facing different challenges and opportunities in meeting the information needs of a new generation of users. It is important to ensure that libraries have the right number of people with the right skills and attributes in the right place at the right time. There are a number of issues that need to be considered to achieve this. This paper summarises the key findings from research into the trends and issues affecting workforce planning in New Zealand university libraries. These are not unique to New Zealand and other locations may benefit from these findings. First and foremost it is essential to recruit and retain staff who are skilled and innovative as well as flexible and adaptable. The staff we recruit should also reflect the increasingly transnational, diverse users we serve. Alongside the need for new and talented staff are the concerns around the retirement of experienced staff over the next decade. This is a double-edged sword as many will retire but on the other hand many older people are working longer. This requires the fostering of knowledge transfer opportunities in both directions and career development pathways for younger staff. Are we there yet? Do we have the staff we need to meet the needs of new generation learners? This paper summarises the key findings from research into the trends and issues affecting workforce planning in New Zealand university libraries. These are not unique to New Zealand and other locations may benefit from these findings. I conducted interviews with three different groups of participants. The first group was senior library staff, in most cases the university librarian from seven of the eight university libraries. The second was a very small group of qualified librarians born in or after 1975 who responded to a call for volunteers from the three universities with a campus in Auckland. The third group was senior human resources staff based in Auckland who provided a broader university context. The participants were asked to identify what they considered to be the main issues and trends affecting universities and libraries in New Zealand in the next five to ten years and how they impact on workforce planning. Not surprisingly these were very similar to the issues and trends affecting libraries in other countries such as Australia, the UK, Canada and the USA. They include technological changes, library staff skills, service models, research support, funding and accountability. 1. University/Library trends and issues 1.1. Technological changes affecting libraries The participants agreed that advancing and converging technologies are having a truly disruptive effect on the library as we know it and it will be important to take these changes into account as libraries increasingly interact with users in an online environment via the library website, learning management systems, mobile technologies and social networking tools. It is important that librarians work with the complexity and uncertainty of the digital future to ensure they are able to meet the needs of the new generation learners (Walter & Williams, 2010). It was also agreed that cloud computing or software as a service should be more fully explored to further enhance user experience by providing rapid and seamless access to the resources they require (Corley, 1999). 1.2. Library staff skills Highly-skilled, e-savy staff are a key element for the future if libraries are going to remain relevant in a primarily digital world. This will mean changing the staff profile and perhaps reducing the number of staff requiring a professional library qualification and considering qualifications and expertise in other areas such as data management and curation. This brings into question the relevancy of the Library and Information Science (LIS) qualifications and New Zealand is not alone in raising concerns in this area. It was felt that the educators do not really understand the increasingly complex library environment and the needs of academic libraries, particularly in the areas of information technology and data management and that the programmes need to be broader especially in the digital environment and scholarly communications areas. There is concern that new graduates are not adequately equipped for the jobs they are applying for. It was also acknowledged that libraries need to be looking more broadly for specialist skills in areas such as business, marketing, web development and computer science. The participants stated that universities need to be more twenty-first century and aware of international trends, so that they can plan for the unknown and keep a finger on the pulse of changes in service models. A major shake-up of scholarly communication and knowledge management over the next five years will impact on the skills and knowledge required by staff to lead these changes. Information literacy skills have become ever more important as the knowledge landscape grows in volume and complexity (Law, 2010). The participants agreed that it is timely to look more broadly at academic literacy which takes into account areas such as digital rights management, copyright, accessibility compliance, reference citation and plagiarism. These are all areas in which librarians are well-versed and could provide assistance to staff and students (Sutherland, Torricelli, & Karg, 2002). Ongoing change is an important factor and librarians need to continually look at the relevance of the library within the institution and if necessary adapt library operations and the skills of librarians to keep abreast of these changes. Strong leadership and management are very important to ensure that these changes are implemented so that the library retains its relevance within the university.


Software system qualities at Enterprise Resource Planning (ERP) play an important role in the business sector. The aim of this study is to determine if airline companies are successfull in application of ERT. Here likert scales are utilized and analyzed by means of the Analytic Hierarchy Process (AHP). Accordingly, two regardable airline companies in Turkey with 60 workers from pre and up positions are participated in the questionnary process of this research. According to the comparison results, strong and weak aspects of theses companies based on their different software systems are found to be as preferenced priorities in aviation sector competition.

The power in the direct-drive wave power generation system is intermittent and fluctuating, and the electric energy it generates cannot meet the power quality requirements of the load directly. In order to stabilize the output of the wave generator, hybrid energy storage can be added to its output side to achieve voltage and power stability. A perfect control strategy of the hybrid energy storage device can reduce the number of charging and discharging of the energy storage device, so as to effectively extend the service life of the energy storage device. This paper proposed a hybrid energy storage power distribution strategy for the wave power system to stabilize power fluctuations, built a miniature direct-drive wave power DC system model, and used the hybrid energy storage to stabilize its output voltage. In this paper, based on the EMD (Empirical Mode Decomposition) method, the Hilbert transform was introduced to obtain the real-time frequency domain relationship of the power signal, and the minimum frequency aliasing method was adopted for power distribution accordingly. After that, for the purpose of stabilizing the DC bus voltage, an energy management strategy considering the state of charge (SOC) of the energy storage device and a reasonable crossover point was designed, and a simulation model was built in Matlab\Simulink to verify and analyze it.


The Freund–Rubin mechanism is based on the equation Rik=λgik (where λ>0), which, via Myers' theorem, implies ''spontaneous'' compactification. The difficulties connected with the cosmological constant in this approach can be resolved if torsion is introduced and λ is set equal to zero, but then compactification ''by hand'' is necessary since the equation Rik =0 can be satisfied both on compact and on noncompact manifolds. In this paper we discuss the global geometry of Ricci‐flat manifolds with torsion, and suggest ways of restoring the ''spontaneity'' of the compactification.


On 11 May 2009 at 11:02 am PDT, the Space Shuttle Atlantis lifted off the launch pad on the fifth and final mission to service t h e H u b b l e S p a c e Telescope (HST). The purpose of this mission was to replace various instruments aboard the HST. The renovations included replacing various scientific instruments as well as non-scientific items such as gyroscopes, batteries and thermal blankets. The renovations to the HST should keep it operational and delighting astronomers and the general public for the next five to ten years (for images, check out http://hubblesite.org).


The recent developments of automated data collection and remote access technologies at synchrotron facility are highly remarkable. Here I describe our recent attempt to identify phosphates using their anomalous signals without visiting synchrotron facility. Crystals were screened using automated data collection with the X-ray at the wavelength of 1.0 Å. Then the solvent around the qualified crystals was removed by deep-UV laser ablation. The diffraction datasets were subsequently collected from the solvent-removed crystals using the X-ray at the wavelength of 2.7 Å. Anomalous Fourier map from the dataset collected with 2.7 Å X-ray was superposed on the electron density map calculated from the dataset collected with 1.0 Å X-ray. The two maps clearly indicated the positions of non-Carbon/Nitrogen/Oxygen atoms in the crystal. Our trial proved that considerable parts of the experiments in the synchrotron facility could be performed from the remote site.


We have presented a numerical technique for analyzing one-dimensional transient temperature distributions in a circular hollow cylinder that was composed of functionally graded ceramic-metal-based materials, without considering the temperature-dependent material properties. The functionally graded material (FGM) cylinder was assumed to be initially in a steady state of gradient temperature; the ceramic inner surface was exposed to high temperature, and the metallic outer surface, which was associated with its in-service performance, was exposed to low temperature. Then, the FGM cylinder was cooled rapidly on the ceramic surface of the cylinder, using a cold medium. The transient temperature and related thermal stresses in the FGM cylinder were analyzed numerically for a model of the mullite-molybdenum FGM system. The technique for analyzing the temperature distribution is quite simple and widely applicable for various boundary conditions of FGMs, in comparison with methods that have been proposed recently by other researchers.


Background: Multiple myeloma (MM) is twice as common in Blacks compared to Non-Hispanic (NH) Whites and Hispanics. While treatment and mortality differences have been reported for Black patients with MM compared to NH White patients, there is limited data on Hispanic populations. Furthermore, the factors driving observed differences in MM presentation and treatment responses by race and ethnicity are largely unknown. We investigated demographic, clinical, and molecular features, including tumor mutations and clonal hematopoiesis (CH), in a diverse population of patients with MM to elucidate mechanisms driving clinical disparities.
 Methods: Patients diagnosed with MM who consented to our institutional biorepository protocol were eligible for inclusion. Demographic and clinical data were obtained from cancer registry and abstracted from electronic medical records. MM tumor cells were purified from bone marrow aspirates by CD138 affinity chromatography. DNA was isolated from tumor cells and whole blood for each patient, and whole exome sequencing (WES) data was generated. Tumor somatic mutations were characterized using paired tumor-normal (blood) WES. CH was classified based on blood-derived somatic mutations, using paired tumors and reference populations as germline comparators. Outcomes included overall survival (OS; date of diagnosis to death/last contact) and progression-free survival (PFS; 1 st-line treatment start to 1 st disease progression/death).
 Results: A diverse group of MM patients (n=496) were included: NH White (80%), NH Black (10%) and Hispanic (9%). NH Black and Hispanic MM patients had a younger median age at diagnosis (57 and 53 yrs, respectively) compared to NH Whites (63 yrs, p = 0.0001; Fig A). There was no statistical difference in treatment categories received by race/ethnicity. NH Black patients had a longer time to hematopoietic cell transplant (HCT; 376 days) than NH White or Hispanic patients (248 and 270 days, respectively, p = 0.011). There was an improvement in OS for NH Black (HR 0.49, 95% CI 0.30-0.81) and Hispanic (HR 0.66, 95% CI 0.37-1.18) patients compared to NH White patients, but the association was not statistically significant in Hispanics. In univariable analysis, OS was also associated with age at diagnosis, International Staging System (ISS), treatment with HCT, and treatment regimen category. In multivariable analysis, after adjusting for age, ISS, HCT, and treatment category there was no longer a statistically significant association between OS and race/ethnicity. Although a worse PFS was present among Hispanic patients (adjusted HR 1.45, 95% CI 0.99-2.13), there was no statistically significant difference in PFS by race/ethnicity.
 The most mutated genes in MM tumors were KRAS (24%), NRAS (17%), TP53 (11%), DIS3 (9%), and BRAF (9%) (Fig B). Genes with significantly higher tumor mutation rates in Black compared to NH White patients were SP140 (12% v 4%, p = 0.026), AUTS2 (8% v 2%, p = 0.04), and SETD2 (6% v 1%, p = 0.037). IRF4 was most commonly mutated in Hispanics (11% v 3% in NH White and 0% in Black, p = 0.019). We identified CH using WES in 60 (12%) patients. The most CH mutations were in ASXL1, DNMT3A, and TET2. There was no difference in the prevalence of CH by race/ethnicity (p=0.8). There was a statistically significant difference in OS by race/ethnicity and CH status (Fig C). For NH Black patients, CH (HR 4.36, 95% CI 1.36-14.0) and age at diagnosis (HR 1.08, 95% CI 1.03-1.14) were associated with inferior OS (Fig C). After adjusting for age in multivariable analysis, the positive association with CH status among Black patients was no longer statistically significant (HR 2.72, 95% CI 0.48-15.4). A positive, but not statistically significant, association for PFS in NH White patients with CH was also noted (adjusted HR 1.38, 95% CI 0.95-2.0).
 Conclusions: This is the first study to examine differences in tumor mutation profiles, CH, and treatment among different racial and ethnic groups of patients diagnosed with MM. Our data suggest that age at diagnosis, tumor mutations, and CH may all contribute to clinical disparities observed in patients with MM. Efforts to expand our cohort and incorporate additional molecular biomarkers, epidemiologic characteristics, and clinical parameters are ongoing with the ultimate goal of elucidating targetable biological mechanisms to personalize management and optimize outcomes for diverse patients diagnosed with MM.

An electric instrument known as an energy metre can be used to measure energy use. The cost and frequency of power use are communicated to the consumer in order to avoid large bill utilization. The energy metre displays the number of units utilized and transmits the data to both the client and the electrical board, which aids in the reduction of man-power. The user may monitor their power use from any location and at any time. In this project, we will build our own IoT-based electricity energy metre with the ESP32 and monitor data using the Blynk App. With today's technology, you must go to the metre reading room and take readings. Thus, keeping track of and monitoring your power use is a time-consuming chore. We can utilise the Internet of Things to automate this. By automating distant data collecting, the Internet of Things eliminates the expense. We must choose a current sensor and a voltage sensor so that the voltage and current can be monitored and we can learn about the electricity utilization and overall power utilized.


Many hypotheses have been proposed to explain infanticide, killing the young or destruction of eggs by conspecific adults. We report cases of infanticide in the polyandrous pheasant‐tailed jacana (Hydrophasianus chirurgus) of Taiwan. In 2004, three males and one female bred at our study site. The female mated with the three males sequentially and laid clutches for all of them. Infanticidal behaviour was observed in all males and in all but one clutch, the first clutch of the breeding season. The infanticidal males threw out the first one or two eggs of a clutch, but then accepted replacement eggs and incubated normally. Because the intervals between copulation with different males were short (1–10 days) and sperm can remain viable within the female reproductive tract for at least 4–5 days, sperm competition among the males may have been intense, and the paternity of the first few eggs in each clutch was doubtful. We suggest that male pheasant‐tailed jacana may use infanticide as a strategy to avoid cuckoldry when the paternity of eggs is in doubt.


The endorsed area of Educational and Developmental Psychology is a division of psychology in Australia that continues to transcend many specialisms in the field. Practitioners in this important area of practice, work in diverse fields such as health, disability, schools and geropsychology, to name but a few. The College is fortunate to cater for such an eclectic group of practitioners with a broad base of psychological practice.


In this presentation, we describe measurements from the CMS experiment on the search for possible signatures of the chiral magnetic effect (CME). The CME is usually associated with a possible strong local parity violation in the quark-gluon plasma in the presence of the extremely strong magnetic fields created mostly by collision spectators. Since a correlation between the direction of the magnetic fields and the collision reaction plane is expected, such investigations are performed by analyzing electric charge-dependent azimuthal correlations. These studies are performed in pPb collisions at 5.02 TeV and 8.16 TeV and in PbPb collisions at 5.02 TeV per-nucleon pair centre-of-mass energy. In addition, the search for possible strong Coulomb fields, predicted to be created mainly by collision participants, is performed. To investigate such effects, the difference between the elliptic flow of $D^0$ and $\bar{D^0}$ mesons is measured as a function of rapidity using PbPb data collected in 2018 by the CMS detector. Prospects for future measurements are also discussed. By considering vacuum quark polarization to a quark-antiquark interaction mediated by a non-perturbative gluon exchange, weak magnetic field contributions to different types of couplings of light vector $\rho$ and $\omega$ mesons (and correspondingly axial mesons), with the corresponding form factors, will be presented. Besides the usual (minimal gauge coupling) vector (axial) coupling of vector (axial) mesons to the vector (axial) constituent quark current, anomalous couplings respectively to the axial (vector) quark currents are also found as Wess-Zumino-Witten type. Weak magnetic field contributions for the $\rho-\omega$ vector mixing and $a_1-f_1$ axial mesons mixings are also presented in the limit in which they reduce to the same structure provided by the Nambu-Jona-Lasinio model. Consequences for the vector mesons dominance (VMD) couplings will be presented by considering the low energy pion form factor and the charge symmetry breaking nuclear potential. Contributions for the averaged quadratic radii (a.q.r.) of the vector (axial) mesons are also calculated including their anomalous axial (vector) a.q.r. We consider a novel type of intrinsic half-integer Quantum Hall effect in 2D materials. We conjecture that it may occur in disturbed honeycomb lattices where both spin degeneracy and time reversal symmetry are broken, supplemented with an appropriately fine-tuned chemical potential. Evidence in favor is presented based on Reduced QED and its parity anomaly in (2+1)D, as driven by a specific gap structure. We make contact with a set of (DFT-simulated) materials and properties that might lead to exactly the desirable gap structure. We also dissect the proposal from an edge perspective, highlighting certain subtleties and future research directions to establish whether (or not) the half-integer conductivity is robust from an edge perspective. is based on the MSc thesis work of Lucas Levrouw and ongoing discussions. Strong electromagnetic fields have a significant impact on the physics of quarks and gluons and can be investigated via first-principles lattice QCD simulations. In this talk, I will briefly summarize recent lattice findings about the phase diagram and the equation of state at nonzero magnetic fields. Moreover, I will present first results for the similar situation involving electric fields. In the latter case, two well established methods are found to disagree on the electric permittivity. The importance of implementing a proper regularization procedure in order to treat thermo and magnetic contributions within nonrenormalizable theories is investigated. Our recent works suggest that potential divergences should be isolated into the vacuum and purely magnetic contributions and then regularized, while the convergent thermomagnetic contributions should be integrated over the full momentum range. We call this procedure vacuum magnetic regularization (VMR) scheme, in which divergent quark mass independent contributions are not subtracted, thereby avoiding unphysical results e.g. for the renormalized magnetization. Our results are in very good agreement with lattice data indicating a paramagnetic behavior for quark matter. Within VMR scheme we also consider the effect of a constant anomalous magnetic moment (AMM) of quarks in the chiral symmetry restoration at strong magnetic fields. We discuss strange stars admixed with fermionic dark matter in the presence of a strong magnetic field using the two-fluid Tolman-Oppenheimer-Volkov equations. We describe strange quark matter using the MIT bag model and consider magnetic fields in the range ∼ 1017−1018 G. For the fermionic dark matter, we consider the cases of free particles and strongly self-interacting particles, with dark fermion masses m=5,100,500 GeV. Even though strong magnetic fields contribute to decreasing the total mass of the star, they attenuate the rate of decrease in the maximum mass brought about by increasing the dark matter fraction in the admixed system. We will analize different effects due to the presence of an external electric field, including also a magnetic field and temperature, on a self-interacting scalar charged field according to the λφ 4 theory. The physical scenario corresponds to heavy-light nuclei relativistic collisions (like Cu-Au) where, due to the imbalance in the number of protons, an electric field appears together with the usual external magnetic field generated during the collision. Thermal effects are also present. We will explore the occurrence of electric anti-catalysis, the dependence of the mass on the different effects mentioned above, discussing also the behavior of the residues of renormalons in the theory. We will discuss the important effects of Strong Electric and Magnetic Fields in Superdense Matter inside neutron stars, white dwarfs, and possibly in quark stars. We will show that when these stellar fields are very strong, some others of magnitude larger than the ones at the star's surface, they can deform the stars. Electric fields - due to a quite small net difference between the number density of positive and negative charged particles when compared to the total particle number density presented inside these compact objects - can increase their masses and enlarge their radii. For the case of strong and constant magnetic fields in the star interior, their effects generate a pressure parallel to the magnetic field direction larger than the perpendicular one, breaking the spherical symmetry. These investigations are particularly relevant for magnetars, and also to very fast and magnetic white dwarfs, recently discovered in binary systems but also in isolated stars [1]. Finally, we will show that the electron capture nuclear process and pycnonuclear fusion reactions can impose limits on the intensity of these magnetic fields in the stellar interior [2]. We revisit the calculation of the fermion self-energy in QED in the presence of a magnetic field. We show that, after carrying out the renormalization procedure and identifying the most general perturbative tensor structure for the modified fermion mass operator in the large field limit, the mass develops an imaginary part. This happens when account is made of the subleading contributions associated to Landau levels other than the lowest one. The imaginary part is associated with a spectral density describing the spread of the mass function in momentum. The center of the distribution corresponds to the magnetic-field modified mass. The width becomes small as the field intensity increases in such a way that for asymptotically large values of the field, when the separation between Landau levels becomes also large, the mass function describes a stable particle occupying only the lowest Landau level. For large but finite values of the magnetic field, the spectral density represents a finite probability for the fermion to occupy Landau levels other than the lowest Landau level. Mixed dimensional theories represent an excellent framework to study 2D materials. In this talk I discuss recent advances in the problem of Chiral symmetry breaking, parity violation and gauge invariance in Reduced QED. In this talk, we will present the result of the magnetic screening mass for the neutral pion within the Linear Sigma Model with quarks. The results are valid for all ranges of magnetic field strength and are computed up to 1-loop order. We will discuss the isolation of the vacuum pieces in the computation of the self-energies and the relevance of including corrections in the coupling constants. The effect of a strong magnetic field on the masses of pseudoscalar and vector mesons is analyzed using an extended version of the Nambu-Jona-Lasino model. The analysis takes into account the mixing effects induced by the magnetic field. The importance of a proper treatment of the Schwinger phase that appears in the calculation of the charged meson properties is discussed. Electromagnetic probes, such as photon and dilepton emission, are invaluable tools for characterizing the properties of quark-gluon plasma produced in heavy-ion collisions. Not only can they tell the temperature of the plasma but also its magnetic field. I will review recent results for the photon and dilepton emission from a strongly magnetized quark-gluon plasma. In the leading order, the corresponding rates are determined by the absorptive part of the photon polarization tensor. I will discuss the energy and angular dependence of the corresponding differential rates. The theoretical predictions reveal that the photon and dilepton emissions can be highly anisotropic. The rates also depend nontrivially on the transverse momentum and the invariant mass. I will argue that the observed large ellipticity of the direct photon emission may indicate the presence of a strong magnetic field in heavy-ion collisions. I will also claim that the future measureme


Immediate implant became a treatment of choice in several conditions. However, stability of the implant requires filling the voids with a bone graft or a substitute. The role of Melatonin in bone stimulation was recently considered. Aim of the study: Evaluation of the effect of melatonin granules around immediate implant both clinically and radiographically. Materials and methods: 14 implants were placed in fresh extraction sockets. The patients were divided into 2 equal groups, control and study groups. In the control group gap was filled with Cerasorb bone graft, while in the study group melatonin was added to Cerasorb. Grafts were surrounded by a biocollagen membrane in both groups. Clinical and radiographic assessment was carried out at 1 st , 3 rd , and 6 th post-operative period. Results: No significant difference was recorded between the two groups, while bone density showed significantly higher levels in the melatonin groups. Conclusion: Topical application of Melatonin is recommended in osteotomy sites and around dental implant as a bone stimulator.

We present a novel observer design for a class of single-output nonlinear systems with Markov jumps. The Markov jump process interferes with a deterministic nonlinear dynamics at random times and retains its state for a certain amount of time (dwell time). The estimation process is reset at these random times, depending on the reset values of the state process, and then evolves as a deterministic estimate of the state process itself. The novelty is given by the reset mechanism adopted for the estimation process itself, depending on the reset values of the state process. We prove that, as long as the mathematical expectation of the dwell times has a positive lower bound and the transition rate of the jump process at the first exit time out of any point is bounded, the state estimation error of the switching dynamics asymptotically converges to zero with probability one. The state estimate over each dwell time is designed using the novel technique of ¿output immersion¿.


The two-year-old seedlings of tea plants(Camellia sinensis cv.Tieguanyin and C.sinensis cv.Fudingdabaicha) were grown in pots to study the effects of soil water stress on the antioxidant system.There were four soil water stress treatments: 75%(normal water supply),55%(slightly water stress),35%(mild water stress) and 20%(severe water stress) of field water-holding capacity.The results showed that the producing velocity of O-·2,cell membrane permeability and content of malondialdehyde(MDA) increased in both of cultivars′ leaves under soil water stress;and the activities of superoxide dismutase(SOD),peroxidase(POD),catalase(CAT),ascorbate peroxidase(APX) and glutathione reductase(GR) increased in the leaves of Tieguanyin under slightly stress and mild stress,but decreased under severe stress.The content of ascorbic acid(AsA) and glutathione(GSH) in leaves had the same profiles as the enzyme activities.But in leaves of Fudingdabaicha,the enzyme activities,the content of ascorbic acid(AsA) and glutathione(GSH) increased under slightly stress,while decreased under mild stress and severe stress.Compared with Fudingdabaicha,Tieguanyin presents higher antioxidant capacity,indicating that Tieguanyin has higher capacity to acclimate to different soil water supply than Fudingdabaicha grown under the same habitat.


SYNOPTIC ABSTRACT In this article, we focus on the moderate to large sample inference for a particular family of the Generalized Transmuted Poisson-G (GTPG) distributions for a baseline G, when G follows a Weibull distribution with suitable parameters. We also consider some useful characterizations for generalized transmuted Poisson-Weibull distribution and some other structural properties which were not discussed previously in other works that exist in the literature. We have also utilized three well-known data sets to exhibit the flexibility of this distribution.


This paper presents the impact of microwave penetration depth on the process of heating the moulding sand with sodium silicate. For each material it is affected by: the wavelength in vacuum and the real and imaginary components of the relative complex electrical permittivity εr for a selected measurement frequency. Since the components are not constant values and they change depending on the electrical parameters of materials and the frequency of the electromagnetic wave, it is indispensable to carry out laboratory measurements to determine them. Moreover, the electrical parameters of materials are also affected by: temperature, packing degree, humidity and conductivity. The measurements of the dielectric properties of moulding sand with sodium silicate was carried out using the perturbation method on a stand of waveguide resonance cavity. The real and imaginary components of the relative complex electrical permittivity was determined for moulding sand at various contents of sodium silicate and at various packing degrees of the samples. On the basis of the results the microwave penetration depth of moulding sand with sodium silicate was established. Relative literature contains no such data that would be essential to predicting an effective process of microwave heating of moulding sand with sodium silicate. Both the packing degree and the amount of sodium silicate in moulding sand turned out to affect the penetration depth, which directly translates into microwave power density distribution in the process of microwave heating of moulding sand with sodium silicate.


The effects of cotton leaf crumple disease on components of yield and on symptom expression were examined for cotton inoculated at five growth stages. As a result of virus infection, the total leaf area was reduced and significant reductions in yield were observed, regardless of plant age at time of inoculation. Yield reductions resulted from a smaller number of bolls set and/or a decrease in boll weight. Foliar symptoms were associated with plants inoculated at all five growth stages, but were observed sooner and were more severe for plants inoculated at the 2 -3, 58, and 8 -10 leaf stages than those inoculated at the 14 -16 or 1820 leaf stages. INTRODUCTION Cotton leaf crumple (CLC) is a disease of Upland and Pima cotton (Gossypium spp.) varieties grown in Arizona, California and northwestern Mexico (1, 8). The disease is incited by the whitefly(Bemisia tabaci Genn.) transmitted CLC virus (CLCV) (3, 18, 12) and is characterized by foliar distortion and mosaic (1, 10, 14). Though the virus and its whitefly vector are believed to routinely overwinter on host weeds (4, 7, 11), epidemics occur primarily in years when whitefly populations build up unusually early in the spring, or in cotton fields seeded late and adjacent to previously infected cotton fields. The general view is that CLCV infection does not cause serious damage in cotton, though numerous studies have demonstrated losses ranging from 21 -76% (5, 6, 13, 14). The results of a recent study in which plants were inoculated at three growth stages and subsequently transplanted to a field plot, demonstrated significant yield losses due to reduced boll set and failure of set bolls to open in plants inoculated during the 2 -10 leaf stages (2). Because data interpretation was made difficult due to late season natural infection in the field plot, an additional experiment conducted under more controlled conditions was needed. A greenhouse study was initiated, therefore, in which the effects of the disease on plants inoculated at various growth stages were assessed. MATERIALS AND METHODS Cotton 'Delta Pine 70' plants were inoculated with CLCV using viruliferous whiteflies as previously described (3). Twenty plants /treatment were inoculated at the 2 -3, 5 -8, 8 -10, 14 -16, and 18 -20 leaf stages and are referred to throughout the text as inoculation ages (IA) 1 -5 respectively. Inoculated and noninoculated control (NC) plants were treated with a systemic insecticide to kill whiteflies and maintained in the greenhouse (20 -26 C) for observation. Components of yield were assessed at 2 wk intervals following inoculation of the IA -5 plants and included plant height, number of open flowers, number of green (closed) bolls, the number of mature (open) bolls, and the number of inflorescences (squares plus flowers) produced. The total number of March, 1987 Cotton Report Page 138 bolls/plant was calculated by summing the number of green and mature bolls. Data were analyzed using one -way analysis of variance and the least significant different (LSD) mean separation procedures. The effect of CLC on leaf area was assessed by collecting the primary leaf at the third internode from the apical meristem every two weeks from ten plants /treatment. Leaves were flattened by pressing and photocopied. Leaf area was measured by tracing the photocopy of each leaf with a polar compensating planimeter. At the end of the experiment, the number of green bolls (GB) and mature bolls (MB) were counted for each plant, harvested, and the mature bolls individually weighed. The average boll weight (ABW) for each treatment was calculated, using all mature bolls in that treatment. The mature boll weight (MBW) was calculated as the sum of the weights of the mature bolls from each plant in a treatment. A maximum potential yield (MPY) was estimated for each plant as MPY = MBW + (ABW X GB), assuming all green bolls would mature and contribute to yield. Plants were assigned disease severity ratings at each assessment date based upon the extent of characteristic CLC symptoms in foliage and/or flower petals. The rating system was 0 = no symptoms, 1 = foliar enations and/or one to three symptomatic leaves, 2 = three to five symptomatic leaves, and 3 = greater than five symptomatic leaves. At the end of the experiment (183 days after the first inoculation date), plants were pruned (stubbed) to .5m in height to encourage perennial regrowth in which CLC symptoms are expressed, regardless of the symptom severity associated with annual foliage. After 4 wk, readings were taken to determine the actual % infection. Positive infection was based upon the presence of characteristic CLC symptoms expressed by perennial regrowth. RESULTS AND DISCUSSION Plant heights are summarized in Fig. 1. Earlyinoculated plants (IA -1) were significantly shorter (P < .05) than NC plants through day 92, while the IA -2 plants were significantly taller than NC plants during this period. Between days 112 -150, there was no significant difference in height among the six treatments. At the end of the experiment, IA -2 plants were again taller than controls, however IA -2 plants exhibited an increase in internode length as well as dramatic reduction in leaf size. In no case did these plants appear healthy and vigorous when compared to NC plants. The number of green, mature, and total bolls produced is shown in Fig. 2. From 122 days after first inoculation, plants in the first three inoculation age groups produced fewer green bolls than IA -4, IA -5, or NC plants. By the end of the experiment, IA5 and NC plants produced more green bolls than IA -1 through IA -4 plants. Bolls from IA -2 and IA -3 plants matured significantly earlier than those from other treatments. At the end of the experiment, IA -1 plants had fewer mature bolls than plants in the other groups. The IA -1 and IA -2 plants produced significantly fewer total bolls compared to the other three inoculation age and NC plants by 122 days after the first inoculation. By the end of the experiment, however, IA -1 through IA -4 plants produced significantly fewer total bolls than IA -5 or NC plants. An analysis of inflorescence (square and flower) production indicated a significant decrease in production by IA -1 plants throughout much of the experiment compared to a significant increase in production by IA -2 through IA -4 plants at various times during the study (Fig. 3a, b). However, many of the inflorescences produced by the latter three groups were subsequently shed and thus did not contribute to total yield. Plants in the IA -1 through IA -3 groups appeared to compensate for these losses by initiating a second round of reproductive structures late in the season (Fig. 3); however, the resultant bolls would theoretically be produced too late in the season to contribute to the harvest. All inoculated plants produced leaves significantly smaller than those of control plants at some time during the experiment (Fig. 4). A decrease in effective photosynthetic leaf area is known to contribute to shedding of squares and bolls (9); thus yield is directly related to leaf area. Foliar stunting was observed initially with IA -1 plants and progressed to include all inoculated groups sequentially in the order of inoculation (Fig. 4). March, 1987 Cotton Report Page 139 By the end of the experiment, only the IA -1 plants appeared to have recovered. Given adequate time, all plants may have eventually resumed normal growth of leaves and subsequent production of bolls, but late season boll set would not contribute to yield in a normal field situation. Average boll weight (g) for IA -1 an IA -2 plants did not differ significantly from NC plants (Table 1). However, the average boll weights for IA -3 through IA -5 plants were significantly lower than controls and contributed to a reduced yield. Fewer total bolls were produced by IA -1 through IA -3 plants when compared to IA-4, IA -5 and NC plants (Fig. 2). Thus, boll weight was adversely affected for IA -3 through IA -5 plants, while the total number of bolls produced by IA -1 through IA -3 plants was reduced. Estimated yields based upon the formula given earlier for maximum potential yield indicated that plants in all inoculated treatments had lower overall potential yield than controls (Table 1). Thus, regardless of whether a reduction in boll weight or a decreased number of bolls set resulted, all CLCV infected plants yielded less cotton than healthy controls. Symptom severity ratings were consistently high (3.0) for IA -1 through IA -3 plants throughout most of the experiment (Fig. 5). Mild symptoms (1.0 -2.2) were observed 2 and 3 wks after inoculation of IA -4 and IA -5 plants, respectively, but typically, severe (3.0) symptoms did not occur until the season had progressed (Fig. 5). Though plants infected at earlier growth stages expressed severe CLC symptoms sooner than late -infected plants, the time at which symptoms appear was not directly related to the time of inoculation. Thus CLCV infection may not be reliably predicted based upon the presence or absence of symptoms alone. Table 1.

By introducing two new kinds of topology, named the bounded-closed topology and the strongly bounded-dosed topology, respectively, we establish several basic results of topological dynamics for the functional differential equations (FDE). In this way, the obstacles to powerful applications of the theory of topological dynamics for FDE have been overcome. It has been shown that this approach is quite successful in dealing with FDE. Moreover, the results obtained in this work include the relevant results for the ordinary differential equations (ODE) as special cases.


Between January 1973 and March 1982, 13 patients have been identified who had in addition to a ventricular septal defect, a discrete narrowing of the left ventricular outflow tract. Two patients had tetralogy of Fallot and one a complete atrioventricular canal defect. Two patients had previously undergone repair of a juxtaductal coarctation and one patient banding of the pulmonary artery. Eleven patients, 10 of whom had left ventricular outflow tract obstruction (mean left ventricular aortic pressure gradient =71 -2±35 3 mmHg) underwent excision of a fibromuscular shelf. A myotomy was performed in addition in six patients. The left ventricular aortic pressure gradient measured postoperatively was less than 15 mmHg in all but one patient. In seven patients the shelfwas excised at the time of closure of the ventricular septal defect, but in four patients the left ventricular outflow tract obstruction became manifest later. Two further patients not operated upon have a discrete narrowing of the left ventricular outflow tract with a left ventricular aortic pressure gradient of 5 and 30 mmHg. Two dimensional echocardiographic assessment of the left ventricular outflow tract was performed in eight patients and compared with left ventricular angiography. Echocardiography clearly visualised the fibromuscular shelf and its relation to the ventricular septal defect in each case. In three of the eight patients the shelf was not seen on the left ventricular angiogram. Assessment of the left ventricular outflow tract in patients with ventricular septal defect by echocardiography will allow recognition of left ventricular outflow tract abnormalities. When a discrete fibromuscular shelf is identified we recommend its excision at the time of closure of the ventricular septal defect. This should be performed even in the absence of a left ventricular aortic pressure gradient to prevent the progressive development of left ventricular outflow tract obstruction and associated myocardial changes.


Due to the dramatic rate of urbanisation worldwide, sustainability of global cities is called into question, and there is global agreement that making cities more sustainable is a key priority. Greater use of underground space is one such solution, hence wider adoption of Urban Underground Space (UUS) within the urban environment needs consideration. One way to measure the efficiency of these solutions within the urban environment is to provide sustainability credentials through sustainability indicators. However, a detailed review of the current 'construction sector' sustainability indicator systems (BREEAM, CEEQUAL, etc.) within this research shows that there is a substantial need for a sustainability indicator tool tailored toward UUS. Hence, a new tool, called USPeAR, is proposed, developed on the basis of the SPeAR® framework system revised and restructured for application on UUS projects.

The USPeAR tool includes a series of indicators based on SPeAR®. They have been selected according to the materiality review method introduced by SPeAR® itself. In addition a panel of experts, who are experienced in terms of construction and sustainability, has been surveyed via a questionnaire to inform the development of an appropriate weighting system for the selected indicators. Lastly, a Cost-Benefit Analysis (CBA) method has been combined with USPeAR to identify the most cost-effective solution for the sustainability improvement of a UUS project. The application of the developed tool was demonstrated through two case studies.


This article describes the efforts of water utility personnel to determine whether the level of endemic giardiasis observed in their service area could be attributed to the surface water supply, which is chloraminated but not filtered. Comparison of epidemiological data for the county in which the utility is located with data from another county that used conventionally treated water showed similar incidence rates, partitioning into risk categories, and age distributions for giardiasis. There was no correlation between the location of a giardiasis case and disinfection contact time within the unfiltered water's distribution system.

Experiment is an important part of pathophysiology.There are some shortcomings in the traditional experiment teaching of pathophysiology,especially the ignore of the students` autonomy training is particularly serious.But the PBL method is a good way to solve the problem.If PBL method can successfully applied in the experiments,it will greatly change the insufficient in traditional experimental teaching.


Two experiments were conducted with broiler chickens from 1 day old to 4 wk of age to determine the nutritional value of unextracted and extracted dehulled canola rapeseed (DCS). In exp. 1, raw or autoclaved DCS at levels of 10 and 20% of the diet were compared with extracted DCS at levels of 5 and 10%. The inclusion of extracted DCS in the diet had no adverse effects on the performance of chicks. Dietary levels of 10 and 20% raw DCS resulted in a decrease in feed intake (P > 0.05) and weight gain (P < 0.05) and an increase in feed/gain ratio (P < 0.05). The performance of birds fed autocalved DCS was intermediate between that of birds fed raw or extracted DCS. Experiment 2 involved a comparison of extracted DCS at levels of 0, 10, 20 and 30% of the diet with variable or constant levels of dietary lysine and sulphur amino acids. Dietary levels of 20 and 30% extracted DCS resulted in a progressive decrease (P < 0.001) in feed intake and weight gain, and an increase (P < 0.001) in feed/gain ratio. Lysine su...

Members of the genus Aspergillus are ubiquitous opportunistic saprophytic fungi regarded as major respiratory pathogens in birds, which can cause significant economic losses in chickens, with mortality, decreased weight gain and slaughter condemnations. Initial contamination of broiler poultry farms often occurs through use of contaminated litter or introduction of day-old birds that have received Aspergillus spp. conidia from hatchery facilities. This study evaluated different conditions at the broiler breeder level and tried to ascertain different risk factors connected to this contamination that can thrive in the hatchery. In most modern broiler breeder reproduction farms in Portugal, birds are kept on the ground and eggs are collected by means of an egg belt system. A total of 210 samples were collected from 30 flocks (one sample per variable and per flock). In each flock, the following samples were taken: 30 samples from egg surfaces (10 cm2) of randomly collected eggs from the floor (dirty eggs); 30 samples from eggs from the egg belt system (clean eggs); 30 samples from the egg belt system (10 cm2 of the egg belt surface) (egg belt system). Samples were tested using a swab soaked in distilled water and seeded on Rose Bengal (RB) medium for initial cultivation. The other sample from the egg belt system was performed putting the open RB plate on the running egg belt system for 5 min. Aspergillus spp. were detected in 46.2% of the samples (97/210), namely in 50% of clean eggs and 40% of dirty eggs. In the egg belt system, 56.7% of the samples were positive. Regarding feed and litter samples, 43.3% and 33.3% accordingly were positive. Samples directly collected from birds were 23.3% positive. Specific broiler breeder conditions, feed stuffs and animals are potential sources of fungi contamination in hatcheries and to the chick quality in broiler farms.


The study investigated the relationship between teacher occupational stress and burnout. The sample size of 400 private school teachers of Himachal Pradesh was taken in to consideration which included both primary and secondary school teachers. The test of Teacher stress Survey by Malik, 1993 and Maslach Burnout inventory by Maslach & Jackson, 1981 was used to assess the teacher stress and burnout. Firstly, correlation analysis design was used to see the significant relationship between all the subs components of stress viz., stress related to students, stress related to Parents, stress related to administration, stress related to fellow teachers with Burnout (Emotional Exhaustion, Depersonalization, personal accomplishment). Secondly, multiple regression analysis was also computed to examine the clear picture of relationship among the variables.


Biodegradable, thermosensitive triblock copolymer, PLGA-PEG-PLGA, can be easily fabricated into drug-loaded microspheres or injectable in situ hydrogel system for protein or water-insoluble drugs without use of organic solvent. Aqueous-based microsphere exhibited continuous release of intact insulin in vitro for 3 weeks while the microspheres prepared using dichloromethane showed initial burst and incomplete release. Confocal miscoscopy images of microspheres corroborated the release pattern. Next study with an injectable in situ hydrogel (ReGel ) exhibited zero-order insulin release in vitro and sustained plasma insulin level for 2 weeks in vivo upon single subcutaneous injection in SD rats.


In this paper I will present the melodic tone systems of several JE40 Bantu varieties spoken in the Mara Region, western Tanzania. While it is true that the functional load of tone is greatly reduced in some of these varieties, others have fairly complex tonal systems both on lexical and grammatical level. Furthermore, it is intriguing that these varieties that are spoken in a fairly restricted geographical area have very different tonal systems.


The authors co-taught a variation on the NSF I-Corps Lean LaunchPad Curriculum at Ashesi University in Ghana as an entrepreneurship capstone course. The course content was a good match for the university's mission: Ashesi University College is an undergraduate institution focused on educating the next generation of entrepreneurial, ethical leaders in Africa, and West Africa has many underserved markets and unmet needs that present entrepreneurship opportunities. Students were final year undergraduates with majors in Business Administration or Management Information Systems. The teaching team consisted of an Ashesi faculty member and a visiting faculty member from the US. The question we address is "Can the Lean LaunchPad class be adapted successfully to Ashesi and West Africa?" The paper discusses changes to the curriculum for the local context, implementation, and concludes with suggestions for further adaptations. The authors found that Lean LaunchPad worked well for introducing students to entrepreneurship and evolving a business concept, but found a need for better upfront opportunity analysis, a stronger focus on value proposition and customers prior to creation of a business model canvas, and a greater emphasis on understanding business costs and revenues. We believe some of the lessons learned apply both to using the Lean LaunchPad curriculum in emerging markets as well as for general use in teaching entrepreneurship.


An eight-year old boy who was healthy previously had a history of use of trimethoprime-sulphametoxsazole (TPM-SMX) because of diarrhea ten days before presentation. He was hospitalized because painful swelling occured in the legs under this treatment, he had fever and joint pain for the last five days. In his personal history, there was no pathology except for frequent aphtous ulcers in the mouth and it was learned that he had no familial history of any hereditary or rheumatic disease.


Gastrointestinal stromal tumors (GISTs) have become the focus of much attention in the oncology community this past year. This mesenchymal soft tissue sarcoma of the gastrointestinal (GI) tract is characterized by the expression of a tyrosine kinase, KIT, in the majority of GISTs. The gene KIT, which encodes this tyrosine kinase, has been shown to contain mutations that result in enhanced growth and division. The presence of c-KIT provided rationale for targeting this tyrosine kinase as a potential therapy for GISTs. Two clinical trials have demonstrated impressive activity of a specific tyrosine kinase inhibitor, STI571 (also known as Gleevece, Imatinib Mesylate, and CPG 57148B), in this disease, which previously was poorly responsive to approaches other than surgery. This paper will review the clinical characteristics, prognostic factors, and treatment approaches focusing on GISTs with malignant behavior as well as the role of KIT in this disease. The pathologic features of this disease will be reviewed in the accompanying article by Jonathan Fletcher.


Organization and accounting should be based on accounting principles, which must ensure qualitative preparation of the financial statements. In this case an important role is played by the principle of domination of essence over form. Here is analyzed the main factors of its development and dissemination. Also it is determined the role of IFRS in the spreading of the principle of domination of essence over form in the world and its fixation on the level of normative regulation of accounting in certain countries, including Ukraine. It is defined theoretical preconditions for identifying and removing the existing obstacles in the application of the principle of domination of essence over form in the practice of management, which will ensure qualitative preparation of the financial statements. It is offered to use the principle of property rights theory, the theory of rent and the agency theory to solve the problem of disseverance between owner and manager.


In the geometric data model for spatio-temporal data, introduced by Chomicki and Revesz, spatio-temporal data are modelled as a finite collection of triangles that are transformed by time-dependent affinities of the plane. To facilitate querying and animation of spatio-temporal data, we present a normal form for data in the geometric data model. We propose an algorithm for constructing this normal form via a spatio-temporal triangulation of geometric data objects. This triangulation algorithm generates new geometric data objects that partition the given objects both in space and in time. A particular property of the proposed partition is that it is invariant under time-dependent affine transformations, and hence independent of the particular choice of coordinate system used to describe he spatio-temporal data in. We can show that our algorithm works correctly and has a polynomial time complexity (of reasonably low degree in the number of input triangles and the maximal degree of the polynomial functions that describe the transformation functions). We also discuss several possible applications of this spatio-temporal triangulation.


The aim of this work is to verify the technical feasibility of composting in the case of Marrakech prefecture. On the basis of waste composition and in accordance with the choice of the installation of Marrakech controlled landfill, composting has been considered as the most suitable waste treatment.To ensure the feasibility of composting, physicochemical analyses have been carried out on the fermentable part of waste; analyses on the content of metal elements have also been performed on the fine fraction, since the most important part is located in the same fraction. All parameters determined in the laboratory, have shown that optimal conditions to have good quality compost have been respected. The only restriction identified is the copper content, which should be less than 20 ppm. Generally the low levels of metal element content indicate that the storage and collection conditions of waste have not influenced their quality. On the other hand, the process must be properly controlled and managed, to produce high-quality compost.


Abstract Accurate and fast structure prediction of peptides of less 40 amino acids in aqueous solution has many biological applications, but their conformations are pH- and salt concentration-dependent. In this work, we present PEP-FOLD4 which goes one step beyond many machine-learning approaches, such as AlphaFold2, TrRosetta and RaptorX. Adding the Debye-Hueckel formalism for charged-charged side chain interactions to a Mie formalism for all intramolecular (backbone and side chain) interactions, PEP-FOLD4, based on a coarse-grained representation of the peptides, performs as well as machine-learning methods on well-structured peptides, but displays significant improvements for poly-charged peptides. PEP-FOLD4 is available at http://bioserv.rpbs.univ-paris-diderot.fr/services/PEP-FOLD4. This server is free and there is no login requirement.
