In the present paper a method for deriving stage characteristics, which can provide accurate prediction of a multistage compressor map is presented. The method combines optimization techniques with the principles of stage stacking. The stage characteristics are produced by modifying some initial generic ones, until the desired accuracy in the prediction at selected points on the overall map is achieved. There are several reasons why prediction based on the initial stage characteristics can be inaccurate, the following three being the main ones. The first is due to inaccuracy in the representation of the stage characteristics themselves. The second is due to lack of exact knowledge of the geometric data of the various stages. Finally the third reason consists of the "weak" modelling representation of complex physical phenomena with one dimensional approaches. Therefore, even when the exact stage characteristics are known, this does not guarantee the accurate prediction of the compressor performance. On account of the above, it is preferable to acquire realistic "effective" stage characteristics which can be used for synthesizing overall compressor characteristics and assessing the effects of stage faults. In this paper, both of these aspects are successfully tackled as demonstrated by applying the method to different test cases.Copyright © 1994 by ASME

Westerners in Japan soon find that they have not learned to sit on the floor or, as in some areas, to sleep while squatting on their haunches. Sharing a husband among several women in the same household requires an attitude that must be learned early and effectively, or polygamy cannot operate successfully. Rewards and punishments are used in the learning of culture. Therefore, a person learns the "right culture," suitable to his group and status. Culture is learned over a period of years, usually with difficulty, and is therefore deeply ingrained and difficult to unlearn or even to modify.


Indonesian government has officially issued a policy of moving the State Capital from the Province of the Special Capital Region of Jakarta to Kalimantan Island. The policy has not yet determined the province that is formed for the capital city on the island of Kalimantan. The State Capital transfer policy is planned to be carried out starting in 2020. However, due to Covid-19, it seems that the transfer of State Capital cannot be carried out. Looking at the data on the website of the House of Representatives of the Republic of Indonesia (DPR RI), it appears that there is already a list of Draft Laws on State Capital that are included in the National Legislation Program (Prolegnas). This means that the State Capital transfer policy is really serious about being implemented. Based on some information, the State Capital plan will be based on a smart city. Of course, this is interesting considering that the world is currently leading to the development of a smart city-based region. But the question is whether the State Capital transfer policy is correct from a legal aspect, considering that the State Capital Law has not yet been formed? Then does the smart city-based State Capital transfer policy have an impact on ecology and social welfare? This article analyzes and answers that question. This article analyzes in depth related to the legal aspects of the State Capital transfer policy. This article also analyzes the impact of the State Capital transfer policy. The impacts to be analyzed in this article are ecological impacts and social welfare. The conclusions in this article are specific answers to the questions posed in this article. © 2022 American Institute of Physics Inc.. All rights reserved.

1, , Mary Ann B Minoza 1 and Grace B Oga-ob Every business needs an accountant. The success of the company generally lies in the hands of the accountant whose duties do not only pertain to the preparation of financial reports but also to perform their obligation in conformity with the ethical standards as provided in the Code of Ethics for professional accountants. This study uses the descriptive-quantitative method employing questionnaires as a tool in gathering data in the top 20 corporate taxpayers in Cebu whether the five fundamental principles which pertain to the objectivity, professional behavior, and professional competence and due care, confidentiality and integrity are applied in all accounting activities. The compliance of these ethical standards is the key to determine how accountants give value to their profession. Through this, it will be easy for them to maintain the confidence of the clients as well as to gain public trust. The completion of this study would be beneficial not just for accountants but to other relevant fields of study.


Introduction: Obesity is a widespread disease and was identified as a major risk factor for malignant diseases, including postmenopausal breast cancer. Although the underlying mechanisms are poorly understood, it is known from in-vitro studies that essential functions of natural killer (NK) cells such as targeting tumor cells are disturbed in obese individuals. Thus, the aim of the present study is the investigation of NK cell functionality of obese mice in a postmenopausal breast cancer model.


From every day experience we find that the accepted standards and indices for the quantitative adequacy of the circulating blood, such as hemoglobin-gms and hematocrit percents, are not adequate and do not reflect volume or mass. The laboratory tests that we have habitually adopted as guidelines denote percentage concentration per unit volume and not absolute amounts. There is all the difference in the world between an actual available volume and just a concentration. A patient may bleed to death, and yet, the hematocrit will show no changes; in fact, in some instances, it may rise, which would normally indicate improvement.


A modern FPGA card can be equipped with high bandwidth memory, such as HBM2. Since the amount of the memory is limited on an FPGA, highly parallel data processing becomes crucial on tightly coupled FPGAs by high-density optical integration, e.g., onboard Si-Photonics transceivers. This study presents a scalable distributed radix sorter, and implements it on an eight-FPGA cluster. Each custom Stratix10 MX2100 FPGA card has 819-Gbps memory bandwidth with two HBM2 memories and 800-Gbps network bandwidth with eight custom embedded optical modules. Existing FPGA sorter typically relies on a merge sort. However, it has a severe performance bottleneck at the final stage of data merge, which cannot make the best use of the high memory-to-memory bandwidth on the FPGA cluster. Instead, we implement a radix sort for a 32-bit key range consisting of eight 4-bit counting sorts optimized to the memory-network structure. Each counting sort needs memory read/write access only once through global and local pipelines. We demonstrated a sorting throughput of 37.2 GB/s.


Advances on the catalysts and technologies of preparing branched polyolefins with controllable topology structures are reviewed. Traditionally,branched polyethylenes are obtained by radical polymerization of ethylene,as well as coordination copolymerization of ethylene with α-olefin catalyzed by early transition metal compounds. By combining ethylene oligomerization with in situ copolymerization of ethylene and the produced α-olefin oligomers,branched polyethylenes with different branch lengh and branching degree are also prepared. In recent years,the newly-developed late transition metal catalysts can be used to synthesize not only the branched,hyperbranched and dendritic polyethylenes by ethylene homopolymerization,but also the end-functional polyolefins with controllable topologies by copolymerization of ethylene with polar monomer.


Abstract This paper presents a new original method of selection of main engines for hopper suction dredgers with regard to probabilistic models. It was proposed to use the normal distribution to describe the operational loads of the main receivers. The principles for determination of parameters of load distribution and design power of the main engines were formulated. Lastly, the principles of selection of the size and number of main engines has been proposed.


We report on a 7‐month‐old girl with Smith–Magenis syndrome (SMS) due to a 4.76‐Mb deletion of 17p12–17p11.2 detected by array comparative genomic hybridization. She was also affected with a left‐sided congenital diaphragmatic hernia (CDH) and cardiac anomalies including an atypical atrioventricular canal defect and a cleft mitral valve. To our knowledge, this is the first reported case of a patient with both SMS and CDH. There are numerous chromosomal regions in which duplications, deletions, inversions, or translocations have been associated with CDH, but none have previously been reported at or close to 17p11.2. We discuss candidate genes for the diaphragmatic defect in this patient. Our case demonstrates that it is important to consider the possibility of SMS in non‐isolated cases of diaphragmatic hernia. © 2011 Wiley Periodicals, Inc.


Dehong Dai-Jingpo Autonomous Prefecture,which is located in the border and minority area of southwest China,has many minorities living in poverty.The serious shortage of minority human capital,either in terms of supply or demand,has its root cause in the lack of elementary education.The development of its socio-economic development and the construction of a harmonious society depends on the solution to this problem.The keys to its solution include the improvement of its elementary,adult and vocational education and create a favorable institutional environment.


One of the main industries with reference to Acacia mangium wood utilization is the production of pulp. Apart from yielding papers, pulp has a high potential for cellulose-based product development due to its chemical composition. As for this project, A. mangium pulp is developed into cellulose acetate and evaluated based on the effect of time and pretreatment to the degree of substitution of the acetyl group in the polar hydroxyl alcohol groups of cellulose. The cellulose acetate was produced through a series of acetylation process that includes cellulose activation pretreatment, acetylation using acetic anhydride, and hydrolysis. The samples in which was divided into the treated and untreated pulps underwent different acetylation duration; which includes 24, 36, and 48 hours. Results showed that activated samples are more susceptible to chemical modification compared to the inactivated ones due to the homogeneous accessibility of the hydroxyl group provided through the swelling agent, acetic acid. Meanwhile, the optimum duration in obtaining cellulose diacetate was 36 and 48 hours for the activated and inactivated samples, respectively, as longer period of process enables better extension to the hydroxyl group. The income of this study shows the potential of A. mangium pulp development as well as denoting the factor affecting the cellulose derivation.


Electrical properties such as dielectric constant, dissipation factor, capacitance, and conductivity are some of the properties that are required to be investigated when a novel composite is fabricated. This research aims to achieve a low dielectric constant (less than 4.2), lowered dissipation factor, lowered conductivity by fabricating a novel natural fiber reinforced polymer composite and investigating its properties. In this research, polypropylene with 14 wt% of strontium titanate, 8 wt% of treated flax fibers was fabricated using compression molding and tested for their dielectric and conductive properties. The capacitance and dielectric constant were significantly higher (43 percent) than that of pure PP or PP-flax, and a gradual decrease was observed as the frequency was increased. The dissipation factor and conductivity were found to be higher for pure PP. However, the full composite exhibited moderate conductivity showing that delays in charge losses could occur, making it an ideal composite for dielectric multilayer applications.

Evaluation practitioners in the international development sector have given considerable attention in recent years to process tracing as a method for evaluating impact, including discussion of how to assess the relative importance of causal factors. Despite the increasing interest, there is a relative dearth of examples of practical learning and evidence of applying process tracing in practice. This CDI Practice Paper draws on comparative learning from applying three different types of process tracing in international development initiatives. It argues in favour of a 'middle path' of applying evidence tests and rubrics to structure evaluative judgements rather than formal Bayesian updating or looser forms of process tracing. It also calls attention to the potential added value of taking a participatory approach, offering practical recommendations for how to do this effectively.


A branch and bound algorithm is used to determine optimal spring rates and damping coefficients in flexible structures although the formalism is easily adaptable to designing passive control systems. The goal is to minimize the H/sub /spl infin// norm from disturbance forces to displacements and velocities of selected degrees of freedom. The success of the branch and bound algorithm largely depends upon the quality of upper and lower bounds for the objective function. A comparison of two design problems is made between a tight, but computationally expensive, lower bound, and a simple, computationally cheap, lower bound. Our conclusion is that the extra investment in time to compute the tight bound is well worth the effort and leads to a dramatic savings in overall computation time.


In industry it is sometimes necessary to control temperatures very closely indeed. Here, the need for control to ±0.5°C under industrial conditions is discussed in relation to a counter-pressure autoclave and it will be seen that this problem is largely a measurement one.


Creation of protected areas in the Arctic has been an important element of protection of valuable ecological systems. It is particularly important when nature conservation priorities match the efforts for preservation of indigenous people lifestyles. Combination of both is problematic when industrial activities, such as oil extraction, arrive to such areas. This paper presents the case of the Numto nature park in the oil-rich Russian Khanty-Mansi Autonomous Okrug situated in the subarctic climate. The park was created in the late 1990s to preserve the unique region with high ecological, historical and ethnographic value, as well as to protect the habitat and reindeer herding activities of indigenous Khanty and forest Nenets peoples. Shortly after the creation of the park different claims were put on various use of nature area. Original zoning of the park has been challenged by the ongoing operations of the oil company, Surgutneftegas, that has undertaken attempts to rezone the park areas in order to accommodate expanding oil actives. The most recent zoning attempt endorsed by the oil company in 2014-2015 has involved researchers from different Russian regions that introduced "wise use" principle pioneered by the Ramsar Convention. Next to valuation and mapping of ecologically valuable areas by natural scientists, social scientists were involved for charting socio-economic and cultural properties of the lands used by the indigenous population. The case employs informational governance framework to analyse how and to what extent zoning, as an informational tool, accommodates different priorities and claims. Through the literature analysis, interviews with the stakeholders and surveys, this study concludes that zoning is used to legitimize practices driven by the vested interests. It does not necessarily lead to more sustainability, but rather serves as an additional leverage for powerful actors to exercise authority over other engaged stakeholders. However, inclusion of wide variety of parties and application of the best internationally accepted standards and practices can counterbalance the dominant players vis-à-vis less-powerful actors on the way to finding the middle ground. Arctic-FROST Annual Meeting, St. Petersburg, August 15-16, 2015 25 The development of railroad infrastructure in the Russian North (Sakha Republic): ecology, symbolics and sociality Sigrid Irene Schiesser, University of Vienna, Austria The Ph.D. project explores the (unintended) social, political, economic and ecological transformations in connection to the current realization of the Amur-Yakutsk railroad in Central Yakutia (Sakha Republic). My research is focusing on the actual finishing point of the railroad, which is the village Nizhniy Bestyakh on the Lena River on the opposite side of Yakutsk. My project is engaging in the daily life of the community in Nizhniy Bestyakh, where people face tremendous changes as a consequence of the railroad development. In my paper at the Arctic FROST workshop I will discuss the results of my first field stay in Nizhniy Bestyakh in spring 2015. In the next 1, 5 years my research will explore the manifold ways individuals experience the current situation triggered by this state-planned infrastructural development in Nizhniy Bestyakh. Furthermore, I will analyze how people express their relations to the state and the changing environment. The question of 'sustainability' and 'sustainable development' is crucial for my project and considers cultural, ecological, social and economic sustainability in the region. While extensive resource extraction and the development of industrial zones have long shaped the reality of Yakutia ́s south, Central Yakutia – the homeland of the Sakha (Yakut) nation – has so far not been a locality of large-scale industrial activities. This is about to change now due to the railroad connection. The installation of the "zolotoe zveno", the golden link in 2011 and the arrival of the first freight train in 2014 in Nizhniy Bestyakh were significant steps towards the start of the exploitation of the natural resources in Central Yakutia. Nizhniy Bestyakh plays an outstanding role for the industrial and economic development of the Sakha Republic (Yakutia) and the Russian Federation. Currently, Nizhniy Bestyakh has got 3600 inhabitants and is very multicultural. The village is situated at the junction of roads, on the railroad and on the Lena River. It serves as a hub town and logistical heart, not only for the region, but for the whole Russian Far East. Although it is still a small village, the symbolic, political and infrastructural significance of the village is clear to everyone. The infrastructural developments in the regions have led to cultural and spatial competitions: recently the Sakha have opened a cultural center on the main junction. Nizhniy Bestykah has never had an orthodox church, at the moment one is under construction, next to the Sakha cultural center. Infrastructures are the built and implemented reality of state practices and political decisions, which result in an everyday condition. My project does not only study the railroad development itself, but especially engages in the economic, ecological and social situation that it creates. The realization of infrastructure is highly emotional and is accompanied by hopes, doubts and fears. Furthermore, the railroad development serves as a trigger for further infrastructural implementations: large logistical depots were created and currently the planned construction of three chemical factories near Nizhniy Bestyakh attracts a lot of attention and mistrust against the state and the republic. Many people have protested against the planned chemical factories, because they worry about their kid ́s health, ecological destruction and pollution. So far, the region was only marked by small-scale agricultural activities and people have lived in a fairly pure, industry-free environment. Hunting and gathering in the taiga and fishing on the Lena River are very popular and play a great role in the local identity. On the one hand, many people seem to support the idea of the development of infrastructures for people, meaning all the positive effects of infrastructural development, including a decrease of prices and the creation of jobs as well as the soon-to-be passenger rail connection to Moscow. On the other hand, infrastructures for the state, meaning large scale industrial developments connected to environmental destruction and pollution as well as the in-migration Arctic-FROST Annual Meeting, St. Petersburg, August 15-16, 2015 26 of workers (priezhie), are rejected by many community members. These two infrastructural categories seem to be widely incongruent. My methods include participant observation, semi-structured narrative interviews, expert interviews, media and archival research as well as informal talks with community members. My research will provide a detailed ethnography of the implementation of a railroad in the central part of the Sakha Republic (Yakutia). My goal is to understand the effects of massive state planned infrastructural projects on small communities. My research will contribute to the anthropological literature of the interface of infrastructures and communities. Arctic-FROST Annual Meeting, St. Petersburg, August 15-16, 2015 27 Resource-based development and the socio-economic sustainability of resource communities of the Murmansk region Tuomas Suutarinen, University of Helsinki, Finland Natural resource extraction forms the backbone of the Russian economy. The role of the natural resources is being emphasized in local and regional economies in the Russian North where they play a key role in the economic development as their extraction characterizes the majority of regions and communities in the Russian North. However, the resource-based development of the Russian North, which has reached its current extent majorly during the centrally-led industrial policies of the Soviet era, is unsustainable in the market economy where it is vulnerable to external forces, such as global volatilities of resource prices. Hence, in the changed socio-economic environment after the collapse of the Soviet Union, resource peripheries and single-industry communities of the Russian North have faced significant socioeconomic problems. This has required them to engage in restructuring and economic diversification in their search for sustainable local development because natural resource extraction cannot alone promote the long-term socio-economic sustainability of resource peripheries. My paper is based on my recently published articles related to problematics of resource-based development in the resource communities of the Russian Arctic. I approach sustainable socioeconomic development by the following criteria: (1) the utilization of local resources is based on long-term planning and diverse visions of the local economic potential; (2) the utilization of local natural resources do not damage the long-term potential of local alternative industries and local living environment; and (3) the utilization of local resources respects the social aspects of local sustainable development. In my paper I analyse the challenges of economic diversification in three arctic single-industry resource communities of the Murmansk region; Kovdor, Kirovsk and Revda, whose post-Soviet economic development has followed different historical development paths. Tourism has developed in Kirovsk alongside the mining industry since the 1930s, while mining has been the only significant industry in Revda and Kovdor. However, recently both Kirovsk and Revda have adopted tourism as the main target of their economic diversification. For theoretical approach of the unsustainability of the local economic development I have developed a local resource curse theory that is based on the basic idea that there are negative consequences to sustainable socio-economic d


Let W be an A *-algebra such that any maximal abelian *-subalgebra is regular and such that any quasinilpotent element x in VI satisfies xN=0, with N< oo. Then any irreducible Hilbert space *-representation is at most N-dimensional. If 9X is a C*-algebra, W possesses transcendental quasinilpotent elements if there exists a v E sf with dim = oo. This note is a continuation of [1]. We want to establish an intimate connection between the degree of noncommutativity of a Banach algebra W and the existence of nilpotent elements in W. The proofs are straightforward extensions of the matrix situation and of methods used in [1]. Throughout all Banach algebras are complex Banach algebras with norm I 1, continuous involution * and an auxiliary norm [3] 1 lo which satisfies Ixx*10=IX12. Such Banach algebras are called A*-algebras [3]. In A*-algebras maximal abelian *-subalgebras are necessarily semisimple. We shall further assume that all Banach algebras have a unit, because the adjunction of a unit does not affect the proofs nor the results. A representation 7r always denotes a *-representation on a Hilbert space H,. We say that x E W is n-nilpotent, with n= oo, 1, 2, , if x is quasinilpotent and xr=O but xn-1$O. We begin with a simple lemma, which is probably known. LEMMA. Let 9[ be an A*-algebra such that any x=x* E W has a finite spectrum with at nmost n points; then dim %:t?n2. PROOF. Let 28 be a maximal abelian (semisimple)*-subalgebra of WI. Then the character space Q3 of 23 has at most n elements. Hence any x c 03 has the form x= ji,? A,ei, where the ei are the minimal idempotents of 23. The ei are selfadjoint and it is easy to see that dim ei. ej< 1. THEOREM 1. (i) Let W be an A *-algebra such that any maximal abelian *-subalgebra is regular and such that any quasinilpotent element x in W satisfies xN=0, then an)' irreducible representation r of 9f is at most N dimensional.

Energy efficiency is a primary design goal for future green wireless communication technologies. Multiple-input multiple-output (MIMO) schemes have been proposed in the literature to improve the throughput of communication systems, and they are expected to play a prominent role in the upcoming fifth generation (5G) standard. This paper presents a novel, high-efficiency MIMO decoder based on the K-Best algorithm with lattice reduction. We have designed a novel hardware architecture for this decoder, which was implemented using 32 nm standard CMOS technology. Our results show that the proposed decoder can achieve on average a four-fold reduction in the power costs compared to recently published designs for 5G networks. The throughput of the design is 506 Mbits/s, which is comparable to existing designs.

The use of CBCT data obtained from dental impressions might be indicated to serve as a basis to manufacture lithium disilicate crowns with a marginal fit in the range of clinical acceptance. Furthermore, the results of the present study suggest that new technologies associated with software improvements might enhance the quality of the data obtained from CBCT. Monolithic materials present different transmittances for visible and blue light, thus they should be indicated according to their esthetic and required luting procedures. The dental team should acquire knowledge on the technology and materials, working synergistically with digital technology resources to provide more accurate and predictable treatments for the patient.


In Greek mythology, Cassandra was cursed with a prophetic knowledge of the future that no one would believe. The premise of this mythological prophet is also an apt description of the challenge facing scientists in communicating climate change. Central to addressing this challenge is the ability to examine, interpret and understand the individual scaffolding that underlies people's perception of climate change. Human-centered design incorporates a deep assessment of human needs in the design of systems and services, providing an alternative lens to engage in action towards climate change. Over the course of three separate design classes, attracting a diverse array of students from undergraduate to PhD to professional degrees, from engineers to humanists, we have explored the intersection of design education and climate change communication. In Design for a Habitable Planet, students conducted broad unstructured interviews to populate a matrix of beliefs and experiences around climate change, allowing them...


This paper reports a new method of thin film encapsulation for surface micromachined sensors using an epitaxially grown polysilicon cap layer. This technique saves die area and enables the sensors to be handled in standard mounting processes such as pick and place and is suitable for injection plastic molding. The 'epipoly' encapsulation is designed for a lateral piezoresistive accelerometer, but is broadly applicable. This paper presents an analytic model that describes the deflection of the epipoly encapsulation as a function of pressure, thickness, length, shape, standoff height, venting, sealing, and material properties. This model is verified with Finite Element Analysis (FEA) and experiment.


The product standards of medical devices' registration are important technical document to ensure the quality of medical devices, their acuracy, appropriateness and comprehensiveness are significant important for the using of medical devices.

In this article, we prove the PL analogue of the theorem of Galatius, Madsen, Tillmann, and Weiss which describes the homotopy type of the smooth cobordism category. More specifically, we introduce the Madsen-Tillmann spectrum $\mathbf{MT}PL(d)$ and prove that there is a weak homotopy equivalence of the form $B\mathsf{Cob}^{\mathrm{PL}}_d \simeq \Omega^{\infty-1}\mathbf{MT}PL(d)$. We also discuss how to adjust the methods of this paper to obtain the topological version of our main result.


Recently, a new ICT approach to agriculture called "Smart Agriculture" has been received great attention to support farmers' decision-making for good final yield on various kinds of field conditions. For this purpose, this paper presents two image sensing methods that enable an automatic observation to capture flowers and seedpods of soybeans in real fields. The developed image sensing methods are considered as sensors in an agricultural cyber-physical system in which big data on the growth status of agricultural plants and environmental information (e.g., weather, temperature, humidity, solar radiation, soil condition, etc.) are analyzed to mine useful rules for appropriate cultivation. The proposed image sensing methods are constructed by combining several image processing and machine learning techniques. The flower detection is realized based on a coarse-to-fine approach where candidate areas of flowers are first detected by SLIC and hue information, and the acceptance of flowers is decided by CNN. In the seedpod detection, candidates of seedpod regions are first detected by the Viola-Jones object detection method, and we also use CNN to make a final decision on the acceptance of detected seedpods. The performance of the proposed image sensing methods is evaluated for a data set of soybean images that were taken from a crowd of soybeans in real agricultural fields in Hokkaido, Japan.


The occurrence of Burkitt's lymphoma (BL) following Hodgkin's disease (HD) has not yet been reported. A patient treated for HD by chemotherapy-radiotherapy association developed a BL 6 years later: it was demonstrated by cytological, cytochemical, immunological and cytogenetical--translocation t (8; 14)--characteristics. Our hypothesis is that, in this case, BL may be the consequences of chemotherapy-radiotherapy association.


The dependence on the quantum-well width of the characteristics of ultrafast (THz) current oscillations in resonant tunneling diode nanostructures is investigated through large-scale numerical simulations using non-equilibrium quantum transport equations. It is shown that decreasing the quantum-well width results to higher applied voltage biases in which intrinsic current oscillations occur. This can be attributed to higher resonant-energy level for narrower quantum-well widths requiring a large amount of applied voltage bias for the creation of emitter quantum-well whose coupling with the main quantum well allows the current oscillations to occur. In addition, there is no apparent trend in the relation between the amplitudes as well as the frequencies of oscillations and the quantum-well width.

The article presents the development of an induction heating automated control system $\Phi$ the diffusion welding installation. The area of epy automated system application is the processes of forming permanent joints in space industry. The automated system is designed to control the induction generator, providing heating and cooling of the product during diffusion welding. The system provides communication with the operator's panel OVEN IP320 enabling the operator to monitor the welding process. The panel screen displays a temperature change graph of the process, as well as the current temperature of the part and the power output from the generator. The operator panel is connected to the controller via the RS-485 interface. The system also provides a possibility of adjusting the parameters of the regulating devices, which makes it possible to carry out the welding technology processing. It is possible to save the results of the welding in the form of graphic and text files.


This study reflects a social constructivist theoretical framework in which the zone of proximal development (ZPD) is a central element, as two teaching approaches, communicative language teaching (CLT) and explicit focus on form (FonF) are examined. Research questions include: Are CLT and explicit FonF conducive to reaching the ZPD? Is there a difference in academic achievement in Spanish between students taught with a CLT approach as opposed to an explicit FonF? W hat is the ratio of mother tongue versus target language used in each of the two classroom s studied ? Findings show that the ZPD can be reached through either approach with the use of the appropriate feedback techniques. In terms of academic achievement, the explicit FonF group outperformed the CLT group, but in terms of language use, CLT group engaged in a larger proportion of target language use.

THE subtitle of this book is "A Symposium for Surgeons." It is in fact a collection of papers on nearly all aspects of peptic ulceration written by eight authors, seven of whom are past or present members of the Liverpool school, and edited by the two authors whose names appear on the cover. The work clearly represents the Liverpool school, but it is of some interest to us that three of the authors are past or present members of the Belfast school. Professor Wells states in his preface, "Sonme basic knowledge is assumed." The book is therefore not absolutely comprehensive, so that routine knowledge of clinical features, diagnostic measures, and operative procedures are not all dealt with in detail. More emphasis is placed upon recently acquired knowledge, particularly in regard to etiology, the post-gastrectomy syndromes, and post-operative nutritional problems. The latter chapters, written by Professor Welbourn, are, as one would expect, quite outstanding. The opening article on epidemiology is unusual and highly iniformative. Another interesting feature is the inclusion of English translations from the German of early papers of the great masters of gastric surgery, from Bilroth to Schoemaker. The whole work is of a very high standard and contains a great deal of useful information. It makes an excellent gateway to learning for the serious postgraduate student or intending research worker. The book will be of great interest and value to all practising abdominal surgeons and there is in it much useful information for physicians and gastro-enterologists. For the F.R.C.S. candidate this work will be of considerable value, but the inclusion of descriptions of a number of somewhat bizarre procedures may detract slightly from its value in this direction. A SECOND edition of this important work appears some ten years after the first. It has been considerably enlarged by the addition of six new chapters and four hundred new illustrations and by the expansion of the existing chapters, which have been rewritten. A new chapter Inow introduces the subject of fractures of the facial bones and a separate chapter is devoted to facial injuries in children. A valuable addition is a chapter devoted to fractures of the fronto-ethmoid region and fittingly this has been written in collaboration with neurosurgeons. Dr. Judah Zigmor contributes a comprehensive chapter on X-ray examination of the facial bones in which he details the important projections and techniques for the general survey and more localised …

Several classes of anthropogenic substances modulate endocrine pathways. To date, most of the research has focused on chemical classes such as chlorinated hydrocarbon contaminants, pesticides, or degradation products of high-use industrial surfactants. However, little is known about the environmental impact of another important class of chem icals: hormonally active pharmaceutical products. This deficit of information is surprising, given the biological potencies of these widely used substances and their potential to enter the environment through sewage treatment effluents and runoff from agricultural applications. Estrogenic pharmaceutical products are used extensively in human estrogen-replacement therapy and oral contraceptive formulations. Estrogenic substances are also used as growth enhancement products in veterinary medicine. This report describes the potencies, pharm acokinetics, and metabolic pathways of such estrogenic products. The amounts of pharmaceutical-derived estrogens that reach the environment from doses and usage are estimated. Factors that affect environmental concentrations including metabolism and biodegradation are also considered. Finally, we present both chemical and analytical data, as well as bioassay evidence, that suggest that biologically active concentrations of estrogenic compounds are being released into the aquatic environment.


- The economic dispatch of the Micro-Grid (MG) in the current scenario considers the scheduling cycle with the lowest cost and effectively manages multiple Distributed Generations (DGs) over an extended duration, making it a more appropriate choice for a functional system. The unpredictability of wind and solar energy poses a challenge in solving the economic dispatch problem. Implementing intelligent algorithms and multi-objective optimum dispatching systems has demonstrated significant cost reduction and enhanced environmental sustainability in microgrid operations. The primary objective of the economic dispatch algorithm in the context of a Micro-Grid (MG) is to minimize expenses throughout the scheduling cycle while efficiently coordinating many distributed generators over an extended duration. This makes it highly suitable for operational systems. Due to their inherent variability, the economic resolution of the dispatch problem associated with wind and solar energy requires significant time. Utilizing smart algorithms and multi-objective functions for optimized dispatching generator capacity can potentially.


During the last decades there has been a considerable number of studies showing positive associations between spirituality-religiosity and health. These studies could be unfamiliar to health professionals, because spiritual issues are perceived as personal and private. This present study was conducted to explore the perception and readiness to discuss about spirituality issues during counselling among dietitians and nutritionists.

A cross-sectional survey using self-administered questionnaire was conducted online through google form. The link to the google form was sent to dietitians and nutritionists by email and social media. A total 24 respondents (9 males and 15 females) completed the questionnaire within the study period. Among them, 58.3% reported to have attended formal religious education.

Result shows that all respondents (100%) agreed that faith is important for them while 62.5% would not have problem exploring spiritual issues with someone else. Majority, 91.7% believe that spirituality do play a role in helping patients coping with their illnesses and 75% admitted that they do advised their patients to look to God for strength, support, and guidance during crises. It was noted that 79.2% are aware that there is nutrition guideline from religious perspective, and 62.5% thought that these guidelines may be easier for patient to understand. It was also found that 83.3% felt uncomfortable to talk about spirituality issues during counselling but are willing to talk about it if asked. This could be explained by 58.3% who admitted to have never been trained on inclusion of spirituality in counselling.

In conclusion, the respondents believe that spirituality issues is important but are not comfortable to talk about it with their patients. This is very much influenced by inadequacy of training about spirituality issues.


Abstract Based on the standard quasi-linear pressure–strain correlation model a nonlinear eddy viscosity turbulence closure is developed. In two-dimensional mean-flows it is uniquely determined by three model coefficients. The model coefficients are allowed to adapt to flow conditions described by the invariants of mean-flow deformation and Reynolds stress anisotropy. The adaption is done in a straightforward and inexpensive manner. In the rapid distortion limit the coefficients are based on recent numerical and theoretical predictions for initially anisotropic turbulence. The model performance is furthermore calibrated against DNS data of canonical flows of engineering and geophysical interest. Those are the boundary layer of channel flow, homogeneous shear flow and Ekman flow. The resulting turbulence model is demonstrated to be superior to those based on well-known pressure–strain correlation models. An interpolation procedure is suggested to cover the entire Reynolds stress anisotropy-invariant map.


The restrictions imposed in response to the spread of the COVID-19 pandemic significantly affected people's everyday life, including those of children. For an extended period, children had to deal with the closure of schools and subsequent online teaching, which disrupted their daily rhythms. This study aimed to determine how children coped with the changes in the rhythms of their everyday life. This study provides insight into the diverse coping mechanisms employed by children during challenging times and highlights the importance of rhythm in establishing a sense of normalcy and stability in everyday life. The study is based on semi-structured interviews with children aged 12–17 years living in a small town in the Prague metropolitan area. The results show that the coping strategies adopted in response to the change in baseline rhythm varied greatly among children. Introducing new rhythms into everyday life was a long process, and some children tried to maintain the rhythms created even after returning to classroom teaching.

Herein we report a novel PES UF membrane via blending with a multifunctional comb copolymer containing capsaicin analogue and hydrophilic groups. The copolymer P(H–P–A) was synthesized by a facile free radical polymerization method using poly(ethylene glycol) methyl ether methacrylate (PEGMA), 2-hydroxyethyl acrylate (HEA), and N-(4-hydroxy-3-methoxy benzyl) acrylamide (HMBA) as monomers. The resultant copolymer was then incorporated into PES to prepare PES blend membranes by the classic NIPS method. Specifically, the effects of the P(H–P–A) amount and different copolymer composition in the casting solutions on the structure and properties of the modified membranes were investigated in detail. The surface hydrophilicity and antifouling property of the membranes were remarkably improved, which was demonstrated by surface wettability measurement and BSA filtration experiments. Moreover, the modified membranes showed excellent antibacterial capability against Escherichia coli because of the capsaicin-analogu...


Background: The study was conducted to estimate and compare the validity and performance of two screening methods for urinary schistosomiasis: the interview - reporting blood in urine- and detecting microhematuria by reagent strip. Methods:  In year 2003, 515 schoolchildren from five schools in Abyan and Taiz governorates in Yemen, were in-terviewed by healtworker for hematuria, and then urine samples were collected and tested for microhematuria by urine strip and for the presence and count of Schistosoma hematobium by filtration method. Validity and performance indicators were estimated and compared for the two methods using the filtration method as the reference- standard- test. Results: The mean age of the schoolchildren was 10.7±2.5 years. Boys represented 65% of the sample. The prevalence of the infection as determined by filtration, interview and reagent strip methods was 21.4%, 22.15, and 30.9%, respectively. Sensitivity, specificity, PPV, NPV of the urine strip was higher than the same indicators for the interview method. Combining the results of both screening methods increased all validity and performance indicators. A statically significant ( P < 0.001) association was found between urine strip positivity level and infection intensity. Conclusion: The urine strip had higher validity and performance indicators than the interview method. For its low -cost, simple and rapid application, we recommend using it for screening infected schoolchildren in areas endemic with S. hematobium in combination with the interview method to enhance its performance.

Mass rearing methods on artificial diets and cruciferous seedlings for the diamondback moth, Plutella xylostella L, are reviewed and described briefly.


Organisations are finding it increasingly difficult to create value in the current dynamic, globalised, interconnected, and ever more complex business and technology environments. The Fourth Industrial Revolution (FIR) is set to increase these challenges as a result of the increasing complexity and dynamic changes in market, societal, and technological trends. While current technological trends potentially offer great value to organisations, emerging technological implementations and transformations often fail to realise the desired value-creation outcomes. Following an exploratory study with qualitative interviews, it was determined that most of these challenges to technology-enabled value-creation initiatives, in the current FIR related environment, can be linked to a dynamic capabilities perspective of strategic management. This perspective encompasses the enabling capabilities and strategic alignment between the external environment, an organisation's strategies, its strategy execution, and its capability creation, adaptation, and management.

Glow-discharge polymerisation of acrylic acid, allyl alcohol, vinyl fluoride, 1,1-difluoroethylene, and tetrafluoroethylene on to textile fabrics results in interesting modifications of their properties, including improved antisoil and soil-release properties of Terylene and nylon 6.6, improved water repellency of Terylene and cotton, and improved dyeability of Terylene with basic dyes. The resistance to soiling of Terylene is markedly improved by a very short treatment in an argon glow discharge; possible mechanisms are outlined. Prolonged exposure of Terylene to an argon glow discharge results in an unusual 'sea-shore' structure running perpendicular to the fibre axis.


BACKGROUND: Trunk muscle activity during isometric exercise is altered by external-focus instruction. OBJECTIVE: To check alterations in trunk muscle activity during side plank exercise both with and without instructions to refrain from crushing an item (external-focus instruction method). METHODS: Twenty-one healthy men aged 20–49 participated in this study. Ten trunk muscle activities were measured using surface electromyography during side plank exercises both with and without external-focus instruction. The unpaired t-test or Mann–Whitney U test was used to compare differences between exercise tasks and between sides. RESULTS: Side plank exercise with external-focus instruction increased activity of the upper trapezius, lower trapezius, latissimus dorsi, medial head of the triceps, and internal oblique on the supported side when compared with that without external-focus instruction (p< 0.05 for all). On the unsupported side, side plank exercise with external-focus instruction significantly increased activity of the upper trapezius, lower trapezius, latissimus dorsi, medial head of the triceps, clavicular part of the pectoralis major serratus anterior, external oblique, rectus abdominis, internal oblique, and multifidus when compared with that without external-focus instruction (p< 0.001 for all). CONCLUSIONS: Adding the external-focus instruction method to the conventional side plank exercise may be effective in increasing the trunk muscles' activity.


It remains formidably challenging to produce covalent organic frameworks (COFs) capable of large-scale synthesis and low cost to meet the industrial application demands (e.g., pollutant removal). Here we report using inexpensive 2,4,6-collidine as building unit to produce a series of highly crystalline and robust olefin-linked COFs capable of industrial-scale fabrication by a melt polymerization method. This method not only breaks the dogma that the reactivity of 2,4,6-collidine is too low to serve as COF monomers, but also facilitates the kilogram-scale synthesis and formation of self-shaped monolithic robust foams. The afforded COFs possess extremely low cost (<50 USD/kg), superior to all the reported COFs. More importantly, using one-pot or post-modification methods can conveniently transform neutral COFs to ionic COFs, which can be applied as highly efficient ion-exchange sorbents for scavenging oxoanion pollutants with fast adsorption kinetics, high adsorption capacity, and ultra-low swelling performance. Remarkably, the superior adsorption capacity of a model oxoanion (ReO 4 - ) is the highest among crystalline porous materials reported so far. This work not only expands the scopes of olefin-linked COFs but also enlightens the route for the industrial production of crystalline ion exchange sorbents.


The present invention relates to an improved process for the preparation of fatty acyl derivatives of amino acids in high yield and purity. The condensation products of fatty substances and low er amino acids are known in the art and have been sug gested for use as wetting, dispersing, textile-treating agents, etc. These: products have generally been pre pared by reacting a fatty acylating substance, such as the acid, acid chloride or ester, with an appropriate amino acid in the presense of a base. The products from such processes and the like are obtained often in relatively poor yield with a significant proportion of undesirable by-products which lessens their suitability for certain. uses. It is requisite to the effectiveness of such condensa tion products for certain uses that these agents be em ployed in a substantially pure state. acid amides amino acids may obtained high yield and substantially pure condition by a process conducive of commercial operation. The present invention relates to a lower acid aqueous a ceptor the hydrogen halide, in the acidifying


Abstract Degradation process of Reactive Black 5 (RB 5) by UV/H2O2 oxidation was carried out. The RB 5 degradation kinetics and the effects of its process parameters were studied in detail, such as H2O2 dosage, pH value and dye dosage. Important results were obtained as follows. RB 5 could be completely degraded by UV/H2O2 process. The best H2O2 dosage was 8.824 mM and the optimal pH value was 4 with 17 mg L-1 RB 5. The RB 5 removal was decreased by raising the initial RB 5 dosage. The degradation kinetics of UV/H2O2 process followed one order kinetics and hyperbola kinetics. The instant hydroxyl radical concentration and the instant reaction rate can be estimated in different reaction condition based on two kinetics analysis.

BACKGROUND
 Neurological complications including cognitive impairment (CI) persist among people with HIV (PWH) on antiretrovirals. However, cognitive screening is not routinely.

 OBJECTIVE
 We used an iPAD-based CI screener to cross-sectionally assess CI burden among adults seeking HIV care.

 METHODS
 A convience sample of participants completed BrainBaseline Assessment of Cognition and Everyday Functioning (BRACE), an iPAD-based CI screener developed by Digital Artefacts/UCSD. BRACE includes the following tests: 1)Trail Making Tests (TMT)-Part-A measuring attention/concentration; 2)TMT-Part-B measuring executive function; 2)Stroop-Color measuring processing speed; and 4)Visual-spatial Learning Test (VSLT) measuring visual-spatial memory. Impairment on each test was defined as a T-score ≤ 40. Gobal neuropsychological(NP) function was estimated by averaging T-score performance of the four outcomes with impairment defined as a T-score ≤ 40. A sub-group completed an NP battery concurrently to assess validity of BRACE. An additional sub-group repeated BRACE 4-weeks or >6-months after completing the first tests to evaluate intra-person test-retest reliability. Relevant factors were abstracted from electronic medical records.

 RESULTS
 404 PWH (mean age=53.6; 82% Black; 58% male; 99% on ART) completed BRACE. Impairment for each test was: TMT-A: 34%, TMT-B: 44%, Stroop-Color: 40%, VSLT: 17%; global impairment was 25%. The correlation between global impairment on the gold standard battery and BRACE was 0.63 (n=61; P<0.001), with 84% sensitivity and 94% specificity to impairment on the full battery.

 CONCLUSIONS
 BRACE estimated CI burden in PWH with good correlation with gold standard NP tests, suggesting the validity of this easy-to-use tool in the clinical setting. Even in PWH on ART, CI remains a concern and will continue to affect the care needs of PWH.

We have investigated the contributions of excitation-autoionization and resonant-excitation-double-autoionization indirect-ionization processes to the electron-impact ionization of Fe/sup 15+/ using a close-coupling approximation. The total ionization cross sections are obtained by adding the cross sections for these indirect processes to the direct-ionization cross sections. Eleven autoionizing levels arising from the 2p/sup 5/3s/sup 2/, 2p/sup 5/3s3p, 2p/sup 5/3p/sup 2/, and 2p/sup 5/3s3d configurations, together with the ground 2p/sup 6/3s state, are included in the close-coupling expansion. Large numbers of bound terms of appropriate symmetry are included in the expansion to account for the resonant-excitation-double-autoionization process. The present results are in good agreement with the recent crossed-beam measurement.


The viola or viola de arame (wire viola), an instrument introduced in Brasil in the 16th century by the Portuguese, took on comprehensive historical and social roles. Through it, the musical culture of the dominant classes reached the peasant and the bourgeois production absorbed elements of that culture, which were indispensable to its national language. By the mid nineteenth-century, it was replaced, mainly in urban areas, by the guitar, period that symbolically mark the establishment of new forms of social interaction between the popular layers. Among these, stand out the choroes, ensembles of musicians whose activities have been of paramount importance to the so-called "nationalization of European dances" and the establishment of disk recording from 1902 onwards.

Liver cirrhosis in children and adolescents is a consequence of a variety of chronic liver diseases, metabolic disorders, and genetic diseases. In infants, cirrhosis is most often due to biliary atresia and genetic-metabolic diseases, while in older children it usually occurs as a result of autoimmune hepatitis, Wilson's disease, alpha-1 antitrypsin deficiency, and primary sclerosing cholangitis. Symptoms of cirrhosis in children and adolescents are not specific. In pediatric patients, the first sign of cirrhosis may more often be low weight gain, weakness, loss of appetite, low-grade fever, as well as more specific signs: transient jaundice, mild pruritus, epistaxis, heaviness in the right hypochondrium, changes in liver density on palpation, hyperbilirubinemia, hyperenzymemia, etc. Complications of pediatric cirrhosis are similar to those observed in adult patients and include gastrointestinal bleeding caused by esophageal varices, ascites, and spontaneous bacterial peritonitis. In pediatric practice, special attention should be paid to nutritional correction in liver cirrhosis since children have higher requirements for protein and micronutrients for growth and development. Treatment of cirrhosis-induced portal hypertension in children and adolescents is mainly based on methods developed for adults. The article deals with diagnostic and differential diagnostic aspects of the terminal stage of liver disease in children. The therapeutic management of patients with cirrhosis of the liver and acute renal failure is based on support of various organ functions. Hemodialysis/ plasmapheresis may serve in some patients as an interim therapy before liver transplantation. The indications for liver transplantation and problems arising after surgery are considered.


ions [1]. The material undergoes a magnetic phase transition to a long-range ordered antiferromagnetic state where neighboring planes of spins are aligned antiparallel with parallel alignment within a plane (so called Type I antiferromagnet) [2]. The extended nature of the electron distribution associated with the magnetic 5d electrons often leads to large covalency effects in these materials, and these effects have been a topic of interest for a number of years [3]. These effects are often rather striking as seen in the compound K2IrCl6, where neutron diffraction measurements of the magnetic form factor indicated that about 30% of the Ir moment was actually delocalized and located on the surrounding Cl ions [4].


We reexamine the method of upward integration of a nonlinear force-free field (NFFF), which is, as is well known, an ill-posed problem. It can be modified to a well-posed one by the following means: instead of using finite difference to express partial derivatives, we use smooth continuous functions to approach magnetic field values, write down three field components consisting of amplitude functions multiplying morphology functions, and reduce four basic NFFF equations to ordinary differential ones. They are then solved in an asymptotic manner (zeroth-order, first-order, etc.). Considering the physical meaning of α, we found a self-consistent compatibility condition for the boundary values. Furthermore, a computation algorithm is proposed, similar to the usual time-dependent two-dimensional MHD simulation scheme. This algorithm is steady and robust against the noise in the magnetic field (in particular, the transverse field) measurement and is able to deal with concentrated photospheric currents. The algorithm runs very fast on an ordinary PC and lasts only 6 minutes for the 80 × 60 (x × y) mesh up to a height of 80 (= 216,000 km ∼ 0.3 R☉). So it provides a powerful tool for solar scientists to analyze the magnetic field properties of solar active regions and to make predictions of solar activity.


End-stage renal failure (ESRF) requiring dialysis is a complication of systemic sclerosis. The challenge of performing a distal arteriovenous fistula (AVF) on a scleroderma patient is mainly related to the thickness of the skin. Due to the excessive fibroproliferative response to tissue injury, the closure of the surgical site can lead to compression and clotting of the anastomosis. Skin flap may help the closure but it can be affected by non-healing skin ulcers. These ulcers are often slow healing and unresponsive to traditional treatments; consequently, the patient's quality of life and prognosis may be severely affected (1). We report the effects of a platelet gel for wound healing in a 58-year-old male with scleroderma and renal failure, following AVF surgery. The skin suture compression caused the failure of the fistula on the day after the intervention (2). During a second look we performed a second anastomosis 3 cm over the previous one. We encountered the same anastomosis compression while we were closing the skin, even though the anastomosis was efficient. While the vessels were suitable for a good anastomosis, the skin thickness caused by sclerodermia was the main issue for a negative outcome. We performed a second skin incision with an angle of about 60 degrees starting from the distal angle of the main incision, creating a skin flap (Fig. 1A). This skin flap was transposed on the skin wound above the anastomosis and sutured with absorbable stitches on the subcutaneous layer and the side above the anastomosis with non-absorbable stitches. The skin wound above the anastomosis was closed with no compression on the fistula, ensuring its good performance. The other side was left open (Fig. 1B). After 5 days from the last operation we checked the wound (Fig. 1C). To heal the wound left by the skin transposition we chose to apply heterologous platelet-rich gel (PRG) (3) (Fig. 1D), whose efficacy has been demonstrated in both in vitro and in vivo models (4). Four-weekly medications were performed with this device. Before applying the PRG, the wound was cleaned each time with saline solution. After the application the gel was covered with Bactigras®. After one week, the first granulation spots appeared (Fig. 2A). After two weeks, the wound cleaning showed that the granulation tissue covered all of the wound (Fig. 2B) and the wound edges appeared narrower. By the fourth week, with the last application of PRG, we obtained a coherent granulation (Fig. 2C). In the fifth week we just cleaned the wound and applied Bactigras® (Fig. 2D). We decided to treat the skin portion left open using heterologous PRG that was already used for the treatment of skin ulcers from systemic sclerosis (1). Satisfying results have been also achieved on uremic and diabetic patients suffering from diabetic ulcers, with ulcer healing and a reduction of disease-associated morbidity and lowering health-care costs (5). Our experience confirmed the utility of PRG on wound healing, particularly on a patient suffering from systemic sclerosis.


The overall heat dissipation coefficients of the sandwich panels with bio-inspired lightweight composite cores were analyzed by using the effective medium model, Then the effective heat dissipation objective function of the panel was constructed. The author took advantage of the Latin hypercube sampling method to sample the experimental data and then to calculate it. On this basis, the static and dynamic mechanical objective functions of the panel were obtained by using the response surface method. Finally, the overall objective function was constructed and solved to achieve the target of multi-functional optimization.


This paper describes design and simulation of high power amplifier used in satellite uplink model. In this paper, design procedure of high power amplifier is provided. The complete design process involves device selection, modeling and simulation. The targeted frequency range covers 4.9GHz to 5.1GHz or bandwidth of 200MHz with a center frequency of 5GHz. Design requirements for the small signal gain of high power amplifier is greater than 10.0dB across the band with an output power is greater than 24dBm at the center frequency. The desired requirements are achieved using two stages amplifiers with BSIM (Berkeley Short Channel IGFET Model) transistor model. The transistor selection is done from V-I characteristic curve of BSIM3v3 model which is simulated with Anasoft platform and MATLAB. According to the stability curve, high power amplifier is unconditionally stable all frequencies except from 1GHz to 3GHz. The matching networks are used for providing the maximum possible transfer of power between a source and its load. The simulation model for high power amplifier is constructed and simulation is conducted by using MATLAB. Simulation results show that C band high power amplifier in this paper is able to provide the desired specifications. KeywordsBSIM, C Band Satellite, High Power Amplifier, MATLAB, Uplink Model


Increase in the fast minor component of erythrocyte hemoglobin namely HbAI and AIC has been recently pointed out in cases with carbohydrate intolerance. We had observed the glucose tolerance of the administered (OCs) oral contraceptives were changed in 60% of the cases. So the purpose of the study was to determine the effect of OCs on the levels of HbAI and AIC in women who had normal and abnormal glucose tolerance and compared with those of pregnant and nonpregnant subjects. As the HbAI and AIC values in the group of GTT normal type were little lower than those of the controls results in the group of GTT borderline and diabetic types were found to be elevated. High correlation observed the values of HbAI and AIC. The levels of HbAIC were reflected with the plasma glucose levels of the previous 50 days than those of examined point. They were also discussed with the results of GTT in the pregnant situation and nonpregnant. The relative decrease HbAIC of administering OCs in the GTT normal groups may represent a compensatory mechanism possibly influeneced by the sex steroids. (full text)


This chapter takes aim at a sacred cow in alternative food movements: "local." If practices shape what we care about, then the potential of alternative food movements is not being fully realized by focusing narrowly on local food. After all, foodscapes can be "local," "close," and "compact" and still separate people.


Abstract Background Cerebral microbleeds (CMBs) are common in acute ischemic stroke (AIS) patients. The presence of CMBs increases the risk of hemorrhagic transformation in AIS patients, and it is also closely associated with cognitive decline and even dementia. At present, there exist different opinions on the independent risk factors for CMBs, and there is no consensus on whether there are gender differences in -post-stroke CMB. Therefore, this study sought to investigate gender heterogeneity in the influencing factors for CMBs by studying male and female AIS patients. Methods This was a China-based, Single-center, retrospective review of data from 482 AIS inpatients at the Neurology Department of Hebei General Hospital (NCT05882123). Both demographic and clinical data were collected from the study subjects. Different head magnetic resonance imaging sequences were used to assess the subjects' CMBs, white matter lesions, and old lacunar infarcts (LI). Various statistical methods, including the t-test, χ 2 test, and logistic regression, were used to analyze the gender heterogeneity of the influencing factors for CMBs in AIS patients. Results When compared with the male AIS patients, the female AIS patients were older and had higher total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, ApoA, ApoB, and fibrinogen levels. The female AIS patients also had higher National Institute of Health Stroke Scale scores and hypertension disease composition ratios. By contrast, the proportions of female AIS patients with a history of smoking and a history of alcohol consumption were both lower than the corresponding proportions of male AIS patients. These differences were all statistically significant (p < .05). There were no statistically significant differences in the incidence and severity of CMBs between the male and female AIS patients (χ 2 = 0.851, 3.092, p > .05). The univariate and multivariate stepwise logistic regression analyses confirmed that age (OR = 1.074, 95% CI: 1.013–1.139, p = .016) and old LI (OR = 4.295, 95% CI: 1.062–17.375, p = .041) were independent risk factors for comorbid CMBs in the female AIS patients, while blood glucose (OR = 0.692, 95% CI: 0.494–0.968, p = .031) was an independent protective factor for comorbid CMBs in the female AIS patients. However, these factors were not found to be independent risk or protective factors for comorbid CMBs in male AIS patients. Conclusion There are gender differences in the influencing factors for CMBs in AIS patients. Age, old LIs, and blood glucose are independent risk or protective factors for comorbid CMBs in female AIS patients, although they are not associated with the risk of developing CMBs in male AIS patients.


The present case appears to come into this group, presenting, as it does, the features which Felty describes, including glandular enlargement and pigmentation. It differs, however, in that the leucocyte count is normal, whereas in Felty's five cases leucopenia was a distinctive and constant feature. (Leucopenia, it may be mentioned, is not a feature of Still's disease.) The case differs also to some extent, 'from Felty's cases, in the pronounced cutaneous manifestations, especially. the extreme degree of pigmentation, the morphoea-like lesions on the back of the hands, and the loss of hair on the scalp.

The Brusque Metamorphic Complex (BMC) is one of the main units of the Tijucas Terrain within the Dom Feliciano Belt, located in the state of Santa Catarina in southern Brazil. In the Itapema region, the BMC is composed chiefly of metasediments, including subordinate metabasalts, meta-ultramafic rocks, and clinoamphibole schists. The metavolcanic rocks form 4 m-thick lenses interlayered with metapelites and calc-silicate schists. Based on the observed textures and the associated structural, bulk-rock geochemical, and mineral chemical data, these metamafites and ultramafites were ancient lava flows of tholeiitic basalts and ultramafic cumulates. The mineral parageneses of the metabasalts are albite + actinolite + chlorite + epidote + titanite + magnetite and oligoclase + hornblende + epidote + titanite + magnetite, indicating progressive transformations produced under greenschist to amphibolite facies conditions. Volcanogenic metasediments show the same geochemical patterns as the metabasalts, whereas the metamorphosed ultramafic rocks consist of cumulates generated by crystal fractionation and flow segregation. The studied rocks show similar rare-earth element (REE) patterns, characterized by clearly higher normalized contents of light REEs compared with heavy REEs, without Eu anomalies in the metabasalts and positive Eu anomalies in meta-ultramafic rocks and volcanogenic metasediments. In accordance with the trace element contents that indicate a within-plate nature, the corresponding mafic melts apparently formed in the mantle by partial fusion and were subsequently enriched with crustal components during ascent into the sialic crust. The analysed 143Nd/144Nd and 87Sr/86Sr ratios lie between 0.5123 and 0.5126 and 0.7067 and 0.7086, respectively, and are thus typical of tholeiitic basalts of the continental plateau type. Initial ϵNd(936) values and derived model ages (T DM) between 1028 and 1762 million years support a mantle source or sources, with extraction and emplacement in the Neoproterozoic. Field relations and geochemical data (including isotopic data) indicate the generation of the studied mafic and ultramafic rocks in a continental rift. In the regional geologic context, the formation of the BMC volcanic and metasedimentary units marks a period of fragmentation of the Palaeoproterozoic continental crust. This extensional event is preserved regionally in gneisses from the Santa Catarina Granulitic Complex and the Camboriú Complex.


The 2001 release 1 version of the Library of Congress's Cataloger's Desktop is reviewed. While LC has added new tools, most notably AACR2 and links to Web resources, and has ironed out a number of bugs over the past six years, this product remains functionally the same as it was in 1995. The user interface, search capabilities, internal file linking, customization, and other features of Desktop are illustrated and discussed, along with some of the technical problems encountered over the course of three years in one library's networked experience. Finally, comparisons are made with the recent demonstration version of ClassWeb, the browser counterpart for the Classification Plus portion of Cataloger's Desktop.

Many countries are experimenting with innovative contractual arrangements for the procurement of construction, maintenance and operation of roads. This paper aims to present a cross national comparison of the Finnish and the Dutch Model of Procurement and their respective developmental paths: from the traditional setting where many of the works were still done in-house, to the present mix of innovative practices. From the field research in these two countries a role play/social simulation has been developed. The simulation is an abstraction of the plans to change the traditional prescriptive contracts used in Periodic Maintenance, to more long term and performance oriented contracts that cover a whole road network. A generic version of the game has been built and tested with two different groups. The goal is to play the simulation with civil servants and representatives from the different actors in both countries and discuss the results with national experts. This paper presents the results from the comparison as well as some preliminary results of the social simulation. The insights from these two research activities could be of significant influence as to how the management of road infrastructure assets is organized in the future.


In The Psychic Life of Power, Judith Butler argued a woman "accomplishes" normative femininity by rejecting same-sex pleasure. Butler further argues that normative femininity is maintained by emulating, without fully embodying, cultural ideals of femininity. Yet two questions remain: Given the theoretical framework that Butler articulated, what happens to the bisexual subject who forecloses neither homosexuality nor heterosexuality? If masculinity and femininity are, as Butler suggested, not only accomplishments, but also cultural ideals, what happens to the subject who fails to properly emulate these cultural ideals? Following Clare Hemming's suggestion that bisexual readings can be an "enlightening analytical tool or starting point for knowledge" within the broader history of sexuality, this article argues that in Mrs. Dalloway, Virginia Woolf explores precisely this tension between desire and socially sanctioned femininity through her depiction of three female characters: Sally Seton, Clarissa Dalloway, and Clarissa's rival Doris Kilman. Whereas Sally effectively forecloses her same-sex desire, fully "accomplishing" heterosexuality and consolidating normative femininity, Clarissa perceives her bisexuality as a "failure" to fully foreclose homosexual desire and feels that she has lost normative femininity. Clarissa's loss is further exacerbated by her daughter's friendship with Doris. Rather than read this loss of femininity as mere "gender anxiety" (as Butler might), however, this article returns to the idea of femininity as cultural ideal and argues that Clarissa and Doris exhibit performative melancholia, a melancholia where the subject experiences normative gender performativity as a lost ideal. It is this perceived loss of femininity that ultimately motivates much of Clarissa's behavior, including her rivalry with Doris.


When cognitive radios operate in a network, each link's adaptations impact the decisions of other cognitive radios which spawns an interactive decision processes. The existence of these interactive processes could potentially limit the deployment of cognitive radios as it is difficult to guarantee that the resulting behavior will avoid a tragedy of the commons, much less provide optimal performance. This paper proposes a novel design framework that ensures that cognitive radio interactions are beneficial and reduce sum network interference with each adaptation. Five different approaches to implementing algorithms that satisfy this framework are presented ¿ two of which rely on collaboration and three which permit autonomous adaptations.

This article is a personal faculty perspective regarding academic accreditation. It describes the psychological process and consequences of losing accreditation. Compton Community College was one of the oldest community colleges in California and has served a diverse population of students for over 50 years. As a result of severe administrative and financial problems, the college's accreditation became jeopardized and was actually terminated in August 2006 by the Fiscal Crisis and Management Assistance Team (FCMAT). The college is now considered a district and has developed a partnership with El Camino Community College. In this article we discuss how the faculty responded to the process of closure and how it experienced the psychological stages of death and dying. Finally addressed is the need for hope to regain autonomy and independence in the future.
