Communication in any organization is a complex phenomenon. Public schools are people‐centered enterprises in which the primary tasks of teaching and learning are accomplished verbally. Within each school, the principal is uniquely positioned to regulate these communications activities. The research reported here sought to examine how five school principals managed communications in their schools. Three major questions guided the research. What are the preferred modes and levels of communications activities utilized by principals? What are the major messages communicated through various modes and at different levels by principals? What do the communications activities of individual principals tell us about how principals interpret their leadership role in school, how they set administrative priorities, and how they put their beliefs and values into practice? The findings indicate that the communications activities of school principals are dominated by dyadic interpersonal contacts. The major purpose of these dyadic interpersonal exchanges were maintenance messages which related to policies, procedures, and regulations for organizing, operating and perpetuating the school. As an adaptation to the nature of a principal's work life, each principal demonstrated a pragmatic preference for accomplishing his/her communications through talk even when written messages or other mechanisms for message delivery would have been more efficient. Finally, the principals believed that the success of their communications activities in school was characterized by openness, honesty, high visibility, and the ability and capacity to listen.


Since the early twentieth century, motor vehicles of all descriptions have been central characters in the settlement, governance and representation of Australia. They have been, and remain, objects of desire and exchange, characters in subsistence, ceremonial and market economies, sites of projective identification and spaces of distinctive social experience. Local and national spaces, time, histories and identities are reshaped in and through our car cultures. Represented in paintings, sculpture, films, literature, music, ceremony and other media, vehicles and the roads they travel communicate closely with the aesthetic spirits of modernity and its postmodern discontents. This issue of Humanities Research sets out to explore some of the key conjunctures of Australian nonurban automobility - intercultural exchange and communication, power and social transformation - from the vantage points of history, cultural studies, art history, anthropology, and visual art. The authors in this volume examine the ways in which car cultures in non-urban Australia produce social relationships between car owners, drivers, passengers, their families, and their observers through the mediating forms and forces of moving vehicles, petrol, bitumen, and the inevitable debris of car wreckages and ruins. In this respect, the analyses collected here provide fresh insights into what anthropologist Daniel Miller has called 'the humanity of the car'.1 The idea for this volume emerged as a coda to a symposium, a photography exhibition and a screening program - Cruising Country: Automobilities in nonurban Australia - held at the ANU Centre for Cross-Cultural Research in 2005 (26-28 May).2 The symposium canvassed car-focused histories, artworks, documentary film, ethnography, cultural analysis and personal storytelling offered by researchers, artists, filmmakers, and Aboriginal elders. As the producers of that event, we conceived the term 'cruising country' to conjure and capture the affective experiences of being automobile on a national map where 'country' is a multivalent post-colonial concept of enduring Aboriginal space and place; country is overwritten by tracks, roads, highways and the myriad 'cruising' journeys they have enabled, from the 'first contact' encounters of desert patrol officers to family trips, from rallies to 'grey nomad' adventures, artists' research routes and cinematic narratives (to name only a few that were featured at the 2005 event). Where once the analysis of car culture began in the driveways and petrol stations of cities and suburbs, the Cruising Country project has turned over the engine to confront another set of stories - those we call the 'non-urban'. Here, motor vehicles are seen making tracks across 'the frontier' of the post-colonial nation and carrying research across other romantic tropes of exploration that require ongoing critical attention in the analysis of post-colonial settler societies. The non-urban focus of our theme reframes notions of distance and 'remoteness', and repositions the desert, the bush and suburban fringes at the centre of narratives of Australian automobility. The exponential growth of Australian road construction in the twentieth and twenty-first centuries is intertwined with structural transformations of an economy balancing land-based primary industries (and the regional expansion that followed these developments) with domestic manufacturing and commodity importation and circulation of ever more goods beyond major metropolitan zones. Domestic and regional industrialisation of automotive manufacturing, the normalisation of car ownership, the fading of rail travel as mass experience and the development of a diversified market of road-based tourist travel have solidified automobility as contemporary Australian habitus. Given the ubiquity and normalisation of car travel as the primary everyday habit of mobility in postwar First-World countries, it is actually surprising that there has not been more humanities and social science research into the varieties of automobile experience in Australia, or elsewhere. …


Crocodilians exhibit powerful antibacterial activities in their tissues and blood. The activities have been partially attributed to the presence of a potent serum complement system of proteins that acts in a nonspecific manner to kill bacteria. Complement activation involves activation of complement C3, a component with broad immune and regulatory function. We searched the crocodilian genomes (Alligator mississippiensis, Crocodylus porosus, and Gavialis gangeticus) for complement C3, and found two genes that code for isoforms with quite different sequences. Birds and mammals express only a single isoform of the complement C3 protein. Some snakes were shown to have two C3 genes; however, these encode proteins with very similar amino acid sequences. To date, only fishes were reported to express complement C3 isoforms with diversity similar to that of the crocodilian forms. Phylogenetic analysis suggests the gene duplication leading to the two crocodilian paralogs probably occurred within the order Crocodylia. Both contain signal sequences, putative internal thioesters, potential N-glycosylation sites, and functional domains that would allow them to interact with complement receptors and other complement system components. As has been suggested with fishes, the expression of multiple functional C3 isoforms may allow crocodilians to respond to a broad spectrum of immunological insult.


We investigate GARCH(cid:2)(cid:3)(cid:4)(cid:3)(cid:5) processes and (cid:6)rst prove their stability(cid:7) Using the representation of the squared GARCH model as an ARMA model we then consider Yule(cid:8)Walker type estimators for the parameters of the GARCH(cid:2)(cid:3)(cid:4)(cid:3)(cid:5) model and derive their asymptotic normality(cid:7) We use a residual bootstrap to de(cid:6)ne bootstrap estimators for the Yule(cid:8)Walker estimates and prove the consistency of this bootstrap method(cid:7) Some simulation results will demonstrate the small sample behaviour of the bootstrap procedure(cid:7)


The basic elements of the growth of spherical hailstones are defined by their diameter and speed of free fall as related by the drag coefficient the cloud liquid water hailstones collect, and their heat and mass transfer. Drag coefficients of smooth spheres have been established by Prandtl (1923) and Bilham and Relf (1937). Neglecting radiative losses, the heat transfer and mass transfer, HMT, through conduction and convection, and evaporation/condensation (sublimation) and the accretion of supercooled cloud water droplets are determining the amount of accreted water that can be frozen. Schumann (1938) produced the first mathematical theory of hail growth with the data available. Ludlam (1958) updated the individual terms and accepted Schumann's (1938) assumption that only water can be accreted that is able to freeze. This is equivalent to saying that all the surplus water is shed. This defines the Schumann-Ludlam Limit, SLL. List (1959a) discovered spongy ice, which consists of a growing ice frame that is stabilizing built-in water. This allows unrestricted growth. The thermodynamics of spongy ice (List, 1960) became the basis for the next theory of hailstone growth by List (1963). With the availability of hail tunnels [List, 1959b,1966, List et al (1987) and Macklin (19xx)] major facilities became available to study the growth of hailstones under controlled conditions. On the basis of samples of more than 19 hailstorms List established the main shape as ellipsoidal (70%) with axes ratios 1: 0.8: 0.5, and started to study with his group, spheroidal hailstone, as approximations of the ellipsoidal ones. The main aerodynamic discovery was the finding that spheroidal hailstones fall while gyrating about a horizontal axis. [A gyration is composed of a nutation and a 90 phase-shifted precession of the spin axis that moves on the surface of a cone while gyrating. The axes intersection is at the center of the hailstone. Gyration, contrary to rotation, produces relatively smooth accretions without spikes. Nevertheless, gyration and spin can substantially enhance shedding. Lesins and List (1986) identified 5 types. The most interesting mode occurs at high frequencies (> 19 Hz). Such conditions can occur in free fall as Kry and List (1974) postulated and Stewart and List (1983) experimentally confirmed. This shedding initiates and maintains a warm rain process.


prompt and efficient therapy. Most cases of venereal infection in Britain are dealt with through health authority clinics, and systematic contact tracing is possible. By this means infections may be detected before salpingitis has developed, and treatment at an early stage may prevent it. Unfortunately contact tracing may be less efficient with women in whom subsequent infertility is likely to be distressing than it is with prostitutes.15 Other possible opportunities for detecting infections before salpingitis develops exist at "well-woman," gynaecological, and family-planning clinics, but the chances of a woman presenting in such a clinic when she is in the early phase of a gonococcal infection are small; one study16 gives a figure of 1 detection in 625. Furthermore such clinics do not possess the organization, equipment, and expertise for diagnostic precision. Possibly, high risk patients might be selected for special attention: those for example with premarital or extramarital conceptions, separated from husband for prolonged periods, known to be promiscuous, with a history of previous infection, or currently suffering from trichomonas vaginitis.16 Once the diagnosis has been established it is hard to justify awaiting sensitivity tests. The appropriate drug for initial treatment will depend on the known sensitivities of the common organisms in a particular area at a given time. In the United Kingdom the sensitive:resistance ratio to penicillin of the gonococcal strains is very different from that in America and the Far East,1 being about 4:1 as opposed to 1:4. As soon as sensitivities are available antibiotic therapy should be adjusted as appropriate. To eradicate the disease treatment should be sustained-something not easily achieved in this category of patient.


Objective To examine whether C(-260)T polymorphism in the promoter of CD14 gene is associated with coronary heart disease(CHD)in the Han population of Jiangsu region.Methods Applying polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)methods we analyzed the genotypes of 193 CHD patients,whose coronary lesions were confirmed by angiography,and 225 healthy subjects.The levels of serum lipid and sCD14 were studied by biochemical methods and ELISA method respectively.Results The frequencies of TT,CT and CC genotype of CD14 gene promoter-260 polymorphism were 41.78%,40.89%,17.33% in healthy subjects(control group)and 40.41%,49.23%,10.36% in CHD group,respectively.No significant association was noted in the distributions of genotype and the frequencies of the allele in the site between CHD and control group(P0.05).Conclusions The C(-260)T polymorphism in the promoter of CD14 gene was not associated with CHD in the Han population of Jiangsu region,and it might not be a genetic risk factor of CHD in the Han Chinese.


The placenta is a complex organ with many functions. Anaesthetic drugs however pass across the placental membrane by passive diffusion and in this respect the placenta behaves like any lipid membrane (such as the blood brain barrier or the renal tubule). In the human the barrier between maternal and fetal blood is made up of syncytiotrophoblast, a continuous layer, fetal capillary endothelium and the basement membranes of these two structures which where contiguous become bonded together. This presents a relatively thin membranous barrier of increasingly large surface area as gestation progresses.


The goals of the gynecologic cancer review program conducted at the University of Illinois Hospital were to review the physical aspects and treatment of GYN cancer and related nursing care, and to increase staff sensitivity to cancer patients by helping them gain an awareness of their own feelings about cancer and death. By the end of the program the staff seemed to be more conscious of their own actions in dealing with cancer patients; this was interpreted as a step toward understanding.


In the pathological theory of Oriental medicine, the concept of Ul(鬱) largely comprises the two meanings as follows. One is the concept used as the meaning of pathological state originated from stasis in Qi-Xie(氣血) or the function of internal organs. The other is the concept used as the meaning of Ul-disease(鬱病), which is a group of symptom that is mostly characterized by stasis in function of Qi system. The concept of Ul in the medical classics was originated from "Neijing(內經)", and in this book it was depicted as five-Ul(五鬱). Since the concept of Ul was depicted in "Neijing", many relevant theory about it had been developed on the basis of the theory in "Neijing", and in the theoretical development like this, the concept of Ul had become a little bit complicated. With regard to the historical change like this, this study is going to focus on some argument in Ming(明) dynasty, which asserted the existence of deficiency[虛證] in Ul that had opposed the general thought of that time usually recognizing the concept of Ul as [實證]. In this point of view, this study regards Zhang-zihe(張子和) as a doctor who had made an important role in the theoretical development of Ul after "Neijing", and will newly analyze the theoretical development of Ul on the basis of the Zhang-zihe's Ul theory, which is seemed to have played the main role in the formation of concept of Ul as excessive state[實證].


The synthesis of N-substituted 2-aminothiazoles has been achieved in one-pot by the successive treatment of acetophenones with [hydroxy(tosyloxy)iodo)benzene (HTIB), potassium thiocyanate and appropriate aniline.

immune-mediated cutaneous reactions to drugs are usually categorized into four distinct types: Type 1, immediate; Type 11, cytotoxic; Type III, immune-complex: and Type IV, cell-mediated. Nonimmunologic skin reactions are also recognized. Beyond immune vnonimmune classifications, cutaneous drug reactions are generally described according to morphologic patterns of reaction. Common types of reactivity usually include maculopapular and urticarial eruptions. In addition, less common reactions include fixed drug eruption, hyperpigmentation, vasculitis, erythema multiforme, toxic epidermal necrolysis, photosensitivity, and alopecia. The drugs most frequently associated with these reactions can be identified and the pharmacist, by accomplishing a thorough systematic drug history, may play a significant role in determining likelihood of drug cause.


The utility model relates to a punch, specifically a punch with a fixing device, which solves the problem that a conventional fixing device is time-consuming and labor-consuming due to the fact that a punch needs to be disassembled when being replaced by the conventional fixing device. The punch with a fixing device comprises a punch body, a punch fixed plate and a backing plate fixed to the upper surface of the punch fixed plate. The punch fixed plate is equipped with a punch installing hole in a trace interference fit for the punch body. The upper surface of the punch fixed plate is equipped with a groove and one end of the groove is communicated with the punch installing hole. The punch fixed plate is equipped with a thread hole communicated with the other end of the groove. A push thread mutually matched with the thread hole is arranged inside the thread hole. The end portion of the punch body located inside the punch installing hole is equipped with an annular groove. A steel ball embedded in the annular groove is arranged inside the groove. The punch with a fixing device has the advantages of simple structure and artful design and the fixing device is widely suitable for all punches.


Three different sialic acid-containing building blocks (6–8) were synthesized for use in solid-phase glycopeptide libraries. Investigation of the conditions for glycosylation of threonine (Thr) with various sialic acid donors revealed that the best results were obtained by coupling glycosyl xanthate 2 to the acceptors Fmoc-Thr-OH (5) or the α-azido acid analogue of Thr, 4. Among several catalysts employed, phenylsulfanyl triflate (PST) afforded the best yields. Both the N-Fmoc and α-azido analogues of Thr allowed glycosylation with good stereoselectivity in 80% (→ 8) and 84% (→ 6) yield, respectively. Introduction of a phenylthio group in the 3 position of the sialic acid donor 3, to assist the stereoselective outcome of the glycosylation reaction, gave good results; however difficulties in the removal of the phenylthio auxiliary group made this route less attractive.
 Both building blocks 6 and 8 were successfully introduced in solid-phase glycopeptide synthesis. Interestingly, alkaline deprotection of the Fmoc group of 8, necessary for subsequent introduction of amino acids, resulted in an immediate attack of the α-amino group on the sialic acid methyl ester to form the lactam 14. This side reaction was also observed during reduction of the azido acid building block 6 under alkaline conditions, but could be suppressed by performing the reduction under acidic conditions. Lactam formation was completely avoided by hydrolysis of the methyl ester prior to reduction of the azide.


Two models of standby redundant systems are considered. Failure time distributions are exponential whereas repair time distributions are arbitrary. Model 1 is a 2-unit standby redundant system with failure analysis time and two types of repair. Model 2 has two series subsystems; one is a 2-unit parallel system with s-dependent units; the other has one unit and is given priority in repair. Semi-Markov process technique is used to obtain mean time to system failure, steady-state availability, absorption probabilities, s-expected number of visits to a state, second moment of time in an up state, and s-expected profit.


Cadmium (Cd) concentrations in some phosphorus (P) fertilizers may be high enough to cause significant Cd accumulation in plants. A 2-year fi eld experiment was conducted on a Sultan silt loam (Aquandic Xerochrept) to determine how the availability to cucumber (Cucumis sativus L.) of Cd from a triple superphosphate (TSP) and a western phosphate rock (PR) was affected by rate of Cd input and liming. A water-soluble Cd salt, CdCl2, was included for comparison. Cucumber vine growth increased with increasing TSP application rates but was unaffected by the application of PR or CdCl2. Cucumber fruit yield, however, was unaffected by the application of either P fertilizer or CdCl2. Concentrations of Cd in cucumber vine or fruit responded to increased Cd inputs from PR, TSP, or CdCl2, and the vine was the primary sink for Cd that accumulated in the plant. Both vine and fruit Cd correlated better with soil total Cd than with labile Cd extractable by 0.05 M CaCl2 or DTPA (diethylenetriaminepentaacetic acid). A unique characteristic of cucumber vine- or fruit-Cd is that it was unaffected (P > 0.05) by lime rate and Cd source and not closely related to labile or exchangeable Cd as measured by 0.05 M CaCl2, in contrast to previous fi ndings for other vegetable or grain crops. Root exudates could have controlled the solubility of Cd in the soil. The low availability of Cd from these sources to the plant was evidenced by the low uptake coeffi cient of Cd (0.461 to 1.059) from the soil to the cucumber fruit and low Cd recovery (0.43%) in both vine and fruit of Cd added. Cadmium (Cd) is one of the heavy metals potentially harmful to human health. It is readily available to plants and is not phy- totoxic even at concentrations in crops that can increase human exposure to levels that cause health concerns (Adriano, 1986). Land disposal of municipal and industrial wastes that are used for their fertility benefi ts is an important pathway for the entry of Cd into soil (Wilson, 2001). Another pathway is the application of fertilizers for crop production. This is because some commercial phosphorus and trace element fertilizers contain elevated con- centrations of Cd and other heavy metals (Mortvedt et al., 1981; Raven and Loeppert, 1997; Williams and David, 1973). Since only a small portion of the Cd added is removed by the crop, repeated applications of the fertilizers produce Cd input rates higher than the crop removal, which may lead to Cd accumulation in the soil (Nicholson and Jones, 1994). As a result, there are concerns as to the environmental and health risk from continued use of such fertilizers (McLaughlin et al., 1996). Several studies have revealed a high availability of Cd in P fertilizers to plants. Reuss et al. (1978) found that the application of triple superphosphate (TSP) increased Cd accumulation in radish (Raphanus sativus L.), lettuce (Latuca sativa L.), and peas (Pisum sativum L.). Other investigators also found a signifi cant increase in Cd uptake by grain and vegetable crops following additions of NPK fertilizers to soil (He and Singh, 1994; Grant and Bailey, 1998; Guttormsen et al., 1995). However, there are also fi ndings contradicting these results. Mortvedt et al. (1981) and Mortvedt (1985) showed no signifi cant increase in Cd concentrations in winter wheat (Triticum aestivum L.) or immature corn (Zea mays L.) with normal application rates of TSP containing Cd up to 153 mg·kg-1 or of Zn fertilizers containing Cd up to 2165 mg·kg-1. Whether or not application of a fertilizer will lead to an increase in plant accumulation of Cd may hinge upon factors including input rates of Cd from fertilizers, its solubility, and type of plant species involved (Grant et al., 1998).


With the explosive growth in short texts on the Web and an increasing number of Web corpora consisting of short texts, short texts are playing an important role in various Web applications. Entity linking is a crucial task in knowledge graphs and a key technology in the field of short texts that affects the accuracy of many downstream tasks in natural language processing. However, compared to long texts, the entity-linking task of Chinese short text is a challenging problem due to the serious colloquialism and insufficient contexts. Moreover, existing methods for entity linking in Chinese short text underutilize semantic information and ignore the interaction between label information and the original short text. In this paper, we propose a RoBERTa sentence vector normalization scheme for short texts to fully extract the semantic information. Firstly, the proposed model utilizes RoBERTa to fully capture contextual semantic information. Secondly, the anisotropy of RoBERTa's output sentence vectors is revised by utilizing the standard Gaussian of flow model, which enables the sentence vectors to more precisely characterize the semantics. In addition, the interaction between label embedding and text embedding is employed to improve the NIL entity classification. Experimental results demonstrate that the proposed model outperforms existing research results and mainstream deep learning methods for entity linking in two Chinese short text datasets.

Community-based health care is an important a part of medical care within the least times; in the context of the COVID-19 pandemic, the distinct capacity of trusted community members for social engagement and delivering care where it's needed is ever more critical. This joint WHO, UNICEF and IFRC guidance addresses the role of community-based health care within the pandemic context. It includes practical recommendations for decision makers to help keep communities and health workers safe, to sustain essential services at the community level, and to ensure an effective response to COVID-19. Using this comprehensive and coordinated approach will help countries strengthen the resilience of community-based health services throughout the pandemic, into early recovery and beyond.


We present a general procedure for determining computationally tractable suboptimal designs, associated upper and lower bounds on the optimal expected cost function, and a procedure for determining a suboptimal design which improves these bounds for an important class of large scale, stochastic decision processes. This class, called the multimodule Markov decision process, is distinguished by the characteristic that each element of the vector state process has dynamics that operate independently of the other elements. The general suboptimal design procedure is based on the solution of a subglobal optimization problem for each module, where for each subglobal problem it is assumed that only restricted state information from the composite system is available to its associated module-decision maker. The computational implications of this suboptimal design approach are analyzed. A multi-component replacement example illustrates this suboptimal design procedure, its associated bounds, and a suboptimal procedure which improves these bounds.


Abstract : The liquid nutrient media of Ulengut, Terskiy, Fervoort-Wolfe, and Korthof were bound to be most effective for growth of leptospira. Addition of glycerin and vitamins of the B group had a stimulating effect on growth. Metabolic processes proceeded more intensively in leptospira of the icterohaemorrhagiae type, than in the pomona or grippotyphosa types. Addition of stimulators to Terskiy medium facilitated intensive consumption of aspargic, glutamic, arginine, serine, methionine, and cystine by the microorganisms. (Author)


Fluorine magnetic resonance imaging (19F MRI) is a promising imaging technique for cancer diagnosis because of its excellent soft tissue resolution and deep tissue penetration, as well as the inherent high natural abundance, almost no endogenous interference, quantitative analysis, and wide chemical shift range of the 19F nucleus. In recent years, scientists have synthesized various 19F MRI contrast agents. By further integrating a wide variety of nanomaterials and cutting‐edge construction strategies, magnetically equivalent 19F atoms are super‐loaded and maintain satisfactory relaxation efficiency to obtain high‐intensity 19F MRI signals. In this review, the nuclear magnetic resonance principle underlying 19F MRI is first described. Then, the construction and performance of various fluorinated contrast agents are summarized. Finally, challenges and future prospects regarding the clinical translation of 19F MRI nanoprobes are considered. This review will provide strategic guidance and panoramic expectations for designing new cancer theranostic regimens and realizing their clinical translation.

This paper aims to present a brief overview of the singularities of the management of public contracts, highlighting the important role that the manager must have a commitment to guarantee, efficient administrative and economic outcomes, overcoming the perception of the fulfilled object in each contract under its responsibility.


BACKGROUND
The development of novel and ecofriendly tools plays an important role in insect pest management. Nanoemulsions (NEs) based on essential oils (EO) offer a safer alternative for human health and the environment. This study aimed to elaborate and evaluate the toxicological effects of NEs containing peppermint or palmarosa EO combined with β-cypermethrin (β-CP) using ultrasound technique.

RESULTS
The optimized ratio of active ingredients to surfactant was 1:2. The NEs containing peppermint EO combined with β-CP (NEs peppermint/β-CP) were polydisperse with two peaks at 12.77 nm (33.4% intensity) and 299.1 nm (66.6% intensity). On the other hand, the NEs containing palmarosa EO combined with β-CP (NEs palmarosa/β-CP) were monodisperse with a size of 104.5 nm. Both NEs were transparent and stable for 2 months. The insecticidal effect of NEs was evaluated against Tribolium castaneum and Sitophilus oryzae adults, as well as Culex pipiens pipiens larvae. On all these insects, NEs peppermint/β-CP enhanced pyrethroid bioactivity from 4.22 to 16 folds while NEs palmarosa/β-CP, from 3.90 to 10.6 folds. Moreover, both NEs maintained high insecticidal activities against all insects for 2 months, although a slight increase of the particle size was detected.

CONCLUSION
The NEs elaborated in this work can be considered as highly promising formulations for the development of new insecticides. This article is protected by copyright. All rights reserved.


Abstract Many brown macroalgae contain substantial concentrations of polyphenolic compounds, known as phlorotannins. Previous studies have shown that much of the variation in phlorotannin concentration is correlated with taxonomy and biogeography, but little is known about patterns of variation within species and populations. In this study, we examined intraspecific variation in the phlorotannin content of the intertidal seaweed Ascophyllum nodosum, by testing for differences within as well as between genetic individuals (genets) and populations, and between algal tissues of similar age from juveniles and adults. The results show that variation in the phlorotannin content of annual shoots within primary shoots and genets contributes substantially to the total intraspecific variation. This pattern probably indicates that the phlorotannin content is a highly plastic trait that can be significantly influenced by small-scale variation in extrinsic factors. There were also significant differences in mean phlorotannin content among study sites, and these differences varied significantly between the two study years. The extensive variation within and among genetic individuals and populations shows that it is crucial to use proper sampling designs in field studies comparing phlorotannin levels between different populations, taxa, or experimental treatments, in order to avoid false conclusions. Phlorotannin levels were significantly higher in adult annual tissue than in juveniles in five of six sites, with an overall mean phlorotannin content of 7.8% of dry mass for adult tissue and 5.9% of dry mass for juveniles. This result may be explained by a trade-off between growth and phlorotannin production and a lower mortality risk for larger individuals, leading to a strategy where it is more advantageous for a juvenile to invest in growth than to allocate resources to chemical defence.


Social media is a fact. It grows rapidly. It is not only as a communication media, but also for information exchange. One of them is Twitter. It is text-based sharing media among its users. Based on all categories of sentiment interchanged in Twitter media, central issue could be academically addressed; then, it is able to be methodically converted to become a decision support model (DSM) that is operated to solve the strategic decision problem. Here, "waste' issues were addressed and interconnected insight-parameters were defined. Then, a DSM constructed. Combination of methods fuzzy logic and mathematic successfully used as a main approach of the model. The constructed model is finally able to evaluate a quality of waste management in Indonesia and propose an actionable decision for answering the challenge of waste in Indonesia.


The classification of a large number of images is a familiar problem to the image processing community. It occurs in consumer photography, bioinformatics, biomedical imaging, surveillance, and in the field of mobile eye-tracking studies. During eye-tracking studies, what a person looks at is recorded, and for each frame what the person looked at must then be analyzed and classified. In many cases the data analysis time restricts the scope of the studies. This paper describes the initial use of hierarchical clustering of these images to minimize the time required during analysis. Pre-clustering the images allows the user to classify a large number of images simultaneously. The success of this method is dependent on meeting requirements for human-computer-interactions, which are also discussed.


An examination of the effect of the false-twist process on structure and dyeing behavior of Terylene is described. It was found that if dyed without tension, textured yarns had a higher rate of dyeing than when dyed under tension. However, the textured yarns dyed under tension had a lower rate of dyeing than corresponding flat yarns prepared without the application of the false-twist process. An explanation of these results is given in terms of a structure that on heating leads to a higher lateral order of the morphologic units and thence to an increased formation of voids, but superimposed on which is a system of gross elongated cracks brought about by the false-twist process.


This article aims to focus on the comparative freedom of the writer in composing a text, or the reader in interpreting it. It has been argued that man is a free agent and whatever he writes, he is free in his thinking, writing, etc. This article postulates that his freedom of expression and thought is a near-myth, because essentially, he is not free.  His reality is that he is circumscribed and his creative process is under the impact of his circumstances which he cannot transcend. All talk of freedom in creativity is highly capped by man's incapacity over certain processes which lie outside his control. A plant that comes out of the earth is a left over of the great invisible struggle between the growth potential of the seed and the devastating impact of the negative elements. Similarly, creation or interpretation of the text  is also a process in which freedom is not an absolute. Human mind works in invisible frameworks of time and the political tide.


The intention has this text to argue where measured the representation of the monsters and the monstrosities occurs as discursive construction in the film the Third Edge of the River (1994), Nelson Pereira Dos Santos, who congregates, in one alone body, six of First the Estorias, Guimaraes Rosa, Sequencia, Fatality, the girl of there, the edges of the joy and the Dagobe Brothers.


We present a low power amplifier integrated with a wide swing cascode current mirror (WSCCM) based on PMOS transistors. To derive the low power amplifier a current of 120 uA is required, which is achieved by varying the widths of the transistors. The best result is achieved by varying the widths up to 6um with an output saturated current response of 120.04 uA. SECTPRE of CADENCE design tool is used as the design software to carry out the simulations. The proposed circuits are designed and verified in MIMOS 0.35 um CMOS and BSIM3 transistor model technology. The low power amplifier achieves an output response of 44.71 mV with a minimum power consumption of 0.485 mW.


With Cultural Continuity Theory as a framework, this study used quantitative (N = 204) and qualitative (N = 63) methods to explore how Ghanaian and African-American mothers communicate their motherhood perceptions and identities. Survey, interview, and focus group data obtained from this investigation suggest cultural discontinuity in the rhetoric the participants use to describe their motherhood experiences and identities. Though this multi-method study is meaningful in that it provides a space for the underrepresented voices of African-American and Ghanaian mothers to be heard, it challenges previously held notions of continuity within African-American and African societies. Based on the findings, this study also considers implications relative to the similarities and differences in African-American and Ghanaian motherhood philosophies, and it offers recommendations for future research.


The taxonomic position of the Afro-Neotropical genus Rinamba is discussed and this genus is transferred to the subfamily Doryctinae. New synonyms are suggested: Rinamba Cameron 1912 = Pseudorhoptrocentrus Granger, 1949, syn. n. = Rhoptrocentroides Marsh, 1993; Rinamba opacicollis Cameron, 1912 = Neodoryctes niger Szépligeti, 1914, syn. n.; Hemidoryctes Belokobylskij, 1993 (March) = Atopodoryctes Marsh, 1993 (December), syn. n.; Heterospilus carbonarius Ashmead, 1894 = Hemidoryctes soror Belokobylskij, 1993, syn. n. A key to species of the genus Rinamba is provided.


THE NEWSPAPERS have been full of Labour's plans for nurses over the past few weeks. The reports have ranged from the introduction of the 'super-nurse' on a £30,000 a year salary to new family friendly policies to retain skilled nurses in the NHS. 'Don't believe all you read in the papers', is shadow health secretary Chris Smith's advice. Labour has no plans to pay super-nurses £30,000 a year. It does, however, have a package of initiatives which it believes will reward and retain nurses. Some of the proposals have been developed over the past two to three years, others are new.


The traditional methods for monitoring the VOCs of pollution sources,the principle and the system structure of underway observation based on SOF-FTIR are introduced. Taking the underway observation in Nanjing key areas during the 2014 Youth Olympic Games for example,the scheme of referencing the result of preliminary investigation,combining sampling analysis and determining target components are proposed. The underway observation result showed the advantages of the method in monitoring column concentration and calculating total emission,and the improvement measures in sunshine condition,the underway observation speed and road condition and the limit of the surface wind speed are introduced.

The understanding and representation of spatial evolution over the time are at the core of two PhDs. These studies largely rely on the comparison of diverse inventories of the same territory from tax documents and maps: terriers and compoix. These documents provide a lot of information on the structure of rural and/or urban areas. However, comparing this kind of information, which was compiled in successive periods, is sometimes difficult, especially because of frequent absence of maps related to the registers. Thanks to ANR ModelEspace's work, it is now possible to study these documents by exploiting their topological properties: information from textual and/or planimetric sources is modelled as a graph which permits a comparison in order to analyse the spatial dynamics of land over time. That is why this method for processing spatial data is applied to the territory of Blandy-les-Tours (77) and Saint-Antonin-Noble-Val (82) to observe land tenure, social and landscape dynamics.


Background: Non-erosive reflux disease (NERD) is characterized by typical gastroesophageal reflux symptoms, such as heartburn and regurgitation, but an absence of oesophageal mucosal damage during upper gastrointestinal endoscopy. Although proton pump inhibitors (PPIs) are the first line therapy, almost 50% of patients with NERD fail to respond to this treatment. Traditional Chinese medicine (TCM) can better relieve the symptoms of NERD. Therefore, a randomized controlled trial (RCT) was designed to investigate the efficiency of TCM granules based on Tongjiang (TJ) methodology combined with PPIs de-escalation therapy for NERD patients who did not respond to PPIs alone. Method: This multicentred, double-blinded, RCT with two parallel groups will recruit 174 participants who will be randomized into the TCM granules combined with PPIs de-escalation group (n=87) and the TCM granules placebo combined with PPIs de-escalation group (n=87). Both groups of participants will receive 6 weeks of treatment and 4 weeks of follow-up, and all participants will be assessed for related symptoms, mental health status and quality of life at each visit. The primary outcome measurements include Visual Analogue Scale (VAS) for heartburn and regurgitation and the major symptoms scale. The secondary outcome measurements include PPI withdrawal rate, symptom recurrence rate, minor symptoms scale, SF-36, PRO, SAS, SDS, GERD–HRQL and TCM syndromes scales.Discussion: Previous research has shown that TCM is capable to alleviate NERD symptoms. This trial will help to provide a better understanding of the synergistic efficiency of the combination of TCM and PPIs, to explore whether the dosage of PPIs can be reduced after the supplement of TCM granules and to provide a feasible plan to reduce dependencies or withdraw NERD patients from PPIs. The outcome of this trial is expected to reduce the symptom recurrence rates, lessen patients' physical and psychological burdens, and achieve good social benefits.Trial registration number: Clinicaltrials.gov: NCT04340297


The focus of this article is the role of drawings in the journeys of young children towards literacy. The argument is that young children learn from home contexts a wide range of approaches towards literacy. At school their flexibility in using these approaches is reshaped into narrow versions of literacy based on learning to read, write and become numerate. Children continue to explore alternative modes of representation at home and amongst their peer group in informal learning contexts outside school. The argument is illustrated with examples from a project, which followed the changes in seven young children's drawing behaviours as they made the transition from home to school. It is suggested that we need a radical reappraisal of what it means to be a literate child in 2004; and that the literacy curriculum in early childhood settings needs to be reframed to reflect this reappraisal.

The emergence of chemical biology represents the culmination of multifactorial forces in the fi elds of chemistry, biology, pharmacology, and medicine at the turn of the twenty-fi rst century. Revolutions in genomic sequencing and robotic automation led to improved access to enabling technologies for academic researchers, and molecular biology methods for analyzing and manipulating intricate environmental cellular responses fostered new approaches to understanding biological systems. However, the sequencing of the human genome seemingly posed more questions than provided solutions to therapeutic hypotheses and strategies, and thus the genesis of chemical biology sought to employ the tools of chemistry to illuminate the complex underpinnings of cellular function. To develop novel chemical tools, high-throughput screening (HTS) platforms and concepts traditionally utilized by the pharmaceutical and biotechnology industries for targetcentric molecular discovery have been embraced for in vitroand in vivo-based compound screening. In these chemical genetic systems, the fundamental ability of discrete chemicals to bind to and modulate the function of proteins leads to a phenotypic alteration. Most importantly, in contrast to biochemical HTS assays that screen for molecular binding to a protein with a therapeutic hypothesis, chemical genetic assays do not necessarily preselect for target identity, thus requiring the rate-limiting step of chemical biology: target identifi cation. With this compilation of methods in chemical biology, we seek to enable the discovery of novel chemical biology tools by providing readers with an array of techniques ranging from initial chemical genetic screening to target identifi cation through the central theme of molecules. We have specifi cally organized the book into four parts to highlight essential components of the chemical biology tool discovery process. Part I details platforms for molecular discovery in in vitro cellular systems, and Part II provides in vivo chemical genetic screening protocols organized roughly in increasing order of organism complexity. These methods constitute a broad sampling of current state-of-the-art biological systems and phenotypic readouts for chemical genetic screening in chemical biology. The unifying theme of chemicals in chemical biology necessitates the methods described in Part III, in which compounds are isolated, purifi ed, selected, analyzed, and profi led to create their biological value. And the functional protein targets responsible for their phenotypes can be ascertained through methods described in Part IV for target identifi cation. These four parts, taken together, describe processes for developing molecular tools to dissect biological function, and while no single prescription exists, our aim is to improve the success rate of this fi eld through the dissemination of detailed, experiential knowledge. We are extremely grateful for the tireless efforts of all of our authors throughout the writing and editing stages of this project; their willingness to share their expertise and experience single-handedly creates the value of this book. We also thank Dr. John M. Walker and David Casey for their help, guidance, and responsiveness and for the opportunity to compile this work.

Scenes of lynching, beheadings, corpses… Although easily accessible on the Internet, images of violence are often occulted in the French media. Why are some images shown while others are kept out of circulation? Are some forms of violence unfit to be seen?


In this paper, the behaviors of nanoporous energy absorption systems subjected to cyclic loadings are investigated. The systems consist of hydrophobic mesoporous silica particles immersed in aqueous solutions of sodium chloride (NaCl). In the first loading-unloading loop, increasing NaCl concentration, c, causes only slight increases in infiltration pressure and energy absorption efficiency. In the following loops, however, the system behaviors are strongly dependent on c. As c increases from 0%to25.9wt.%, the recoverability is improved by a factor of 3, indicating clearly that the addition of NaCl has a beneficial effect to promoting the outflow in the nanoenvironment.


Voltage and torque ripples degrade the control precision and increase vibration and noise in electric vehicles, servo systems, and wind generators. To reduce this problem, we propose a new winding method whereby three phase coils each with a different number of turns are wound around each tooth. The proposed winding scheme is also applicable to toroidal winding. The ripple in the back EMF, which was significant in the conventional winding configuration, was reduced to below 1% of the fundamental in the proposed winding scheme. In a similar analysis, the proposed winding scheme reduced the torque ripple by approximately 7% (2.5%).

DAFNE‐Light is the Synchrotron Radiation Facility at the INFN‐Frascati National Laboratory (Rome, Italy). Three beamlines are operational, using in parasitic and dedicated mode the intense photon emission of DAFNE, a 0.51 GeV storage ring with a routinely circulating electron current higher than 1 Ampere. Two of these beamlines—the soft x‐ray (DXR1) and UV (DXR2)—use one of the DAFNE wiggler magnets as synchrotron radiation source, while the third beamline SINBAD (Synchrotron Infrared Beamline At DAFNE) collects the radiation from a bending magnet. New XUV bending magnet beamlines are nowadays under construction and the low energy one (35–200 eV) will be ready for commissioning by the end of 2009. A presentation of the facility will be given together with some recent scientific results achieved at SINBAD and DXR1 beamlines.


The present thesis offers a comparative analysis of the theme of feminine doubling, which has not yet been taken into academic consideration. It examines the strategies of construction of relationships bonding mother-figures, daughter-figures, and father-figures in the various texts selected for inclusion in this dissertation from British and Polish literature. The key argument is that the tie between feminine doubles can be positive. A mother-figure (or the first wife) is capable of sharing her experiences with her daughter-figure (or the second wife). The second pivot of this exploration is the figure of a sexual mother.  The dissertation comprises three parts. The aim of the first section of the thesis is  to provide an introduction to the broad cultural context of the mid-nineteenthto early twentieth-century Polish literature. The second, pivotal part is an exploration of the themes of feminine doubling and feminine sexuality as manifested in the Polish texts, including Narcyza Żmichowska's The Heathen, Maria Konopnicka's "Miss Florentine", Maria Komornicka's "On Father and his Daughter" and Zofia Nałkowska's "Green Shore". It also consists of an interrogation of the shifts occurring in the plot of Charlotte Brontë's Jane Eyre and Daphne du Maurier's Rebecca: these shifts concern the protagonists and the nature of their relationships with the sexual mother-figures. The present analysis stems from the conviction that a comparative reinterpretation of the two novels has been largely overlooked so far. The aim of the thesis is to apply various theoretical approaches that enable the reader to bring together the Freudo-Lacanian psychoanalysis and écriture féminine. The broad psychoanalytical context, including the works of the forgotten Freudian scholar Sabina Spielrein, provides a basis for the comparison. It also enables a profound, intertextual, and inspiring analysis. The thesis is meant to provide a much-needed new reading of Polish women's literature in a comparative structure, so that these texts may be afforded their appropriate position within the British and Polish critique. The innovative features of the research include its comparative character, and the implementation of various psychoanalytical approaches to the Polish works. Additionally, the thesis focuses on literary analysis. It incorporates the findings of various scholars interested in issues associated with "femininity": it emphasises the importance of gender and feminist issues to the literary (re)interpretation of women's texts. The present investigation is not conclusive and should be viewed as a stepping  stone for further comparative exploration of Polish novels penned by women.

By embedding some information into different resolutions of videos and combining the video segments together, the paper proposed a H.264 information hiding algorithm in video stream switching application. Detailed embedding course carries out in the movement vector after H.264 compression, and the embedding needn't to be operated while the video being transmitted, making the real-time performance possibility, which meets well with the aim of the information hiding in stream switching application. Experiment shows that this method increases little bit rate and suitable for the stream switching application.


The robust stability problem of linear time-invariant singularly perturbed systems is discussed, where the system matrix may have a parameter perturbation bounded by the Hα-norm. A sufficient condition for the upper bound of e is given, such that the stability of the actual system (or the full-order model) can be inferred from the analysis of the reduced-order system (or the slow model) in separate time scales.


The hematopoietic stem cells (HSCs) have been unquestionably important to therapies that involve blood and immune system replacement. However, the in-vitro culture and the expansion of HSCs inhibit their application. This work aims to develop a composite biodegradable 3D scaffold that would simulate key aspects of the in-vivo microenvironment (niche) in which expansion of the hematopoietic stem cells takes place in human bone marrow. Hydroxyapatite (HA) has been chosen as a scaffold material because of its biocompatibility and the ability to create an osteogenic scaffold and thereby simulate trabecular bone that is known to be important to the HSC niche in bone marrow. It is hypothesized that the use of a Ca-rich HA scaffold will create a three dimensional, protective environment for HSCs and further promote their in-vitro expansion by releasing Ca ions into the culture medium.
The first part of this study examined the processing of Ca-rich HA and the release of calcium ions into saline over time. The Ca-rich phase was introduced into the HA by an infiltration process and has been shown to release calcium into the culture medium over 42 days. The second part of this study examined the effect of the scaffold material on the fate of human umbilical vein endothelial cells (HUVECS), a well-known endothelial progenitor model. The results showed, for the first time, that at least some HUVEC cells have hematopoietic potential and that the scaffold promoted differentiation down the hematopoietic cell lineage. This is thought to be due to hemangioblast character in the HUVEC cells which is also shared by HSCs. Finally the effects of the scaffold on the in-vitro co-culture of an osteoblast cell line and primary human bone marrow derived HSCs was studied. The infiltrated scaffolds were shown to stimulate the HSC population to differentiate down the hematopoietic lineage and also showed greater potential to differentiate down the HSC lineage in consequent CFU assays.


We give a necessary and sufficient condition for the existence, over a principal ideal domain, of matrices A and B with prescribed invariant factors, such that rank(A−B) is equal to a fixed integer.


ABSTRACT The aim of this study was (i) to identify the key performance indicators that discriminate all-star from non-all-stars players, and (ii) to differentiate winning from drawing/losing teams during the men´s water polo Olympic Games (Tokyo, 2020). The sample consisted of all matches (n = 42) played by 12 teams (156 players). Differences were calculated using the Mann-Whitney U and student-t tests and the binary logistic regression. Minutes per match, goals, action goals, centre goals, extra-player goals, 6-m goals, penalty goals, steals and rebounds discriminated all-star from non-all-star players. However, only minutes per match (OR: 1.105), extra player goals (OR: 1.748), 6-m goals (OR = 3.617) and penalty goals (OR: 2.592) per time played were determined to differentiate all-star players. Regarding the second aim, the following variables discriminated winning from losing/drawing teams: % action goals, % 6-m goals, % penalty goals, team fouls, sprints won, steals and % goalkeeper actions shots. However, only % action goals (OR: 1.153), steals (OR: 1.279) and % action shots (OR: 1.093) predicted the match outcome. Coaching staffs may apply this information to different players, while account for individual differences and functional variability, to optimise practice planning and, consequently, the game performance of individuals and teams.


New chemistry materials were devised for pre university National Certificate (NC) nursing students studying chemistry at a further education college. Previously, preliminary work showed that students felt that the chemistry taught to them was irrelevant, boring and difficult. It was hoped that through an applications-led style curriculum intervention, the chemistry taught would appear to be more accessible and meaningful to student nurses in the context of their lives and careers. This was done by relating the new material, wherever possible, to prior knowledge held by the students from their school experiences, real life working practices, or from their life experiences in general. The order, presentation and sequencing of materials were changed in order to reduce the perceived load on the working memory. In this manner, the learner can focus on important essential material without having to absorb irrelevant detail. It was found that the lecturer and the participating students gave universal support to the new chemistry materials.


Between 1969 and 1975, 34 children aged 16 years and under, with Hodgkin's disease (HD) were treated and followed-up at our department. All patients received a combination of MVPP and radiotherapy. Four children died, three from uncontrolled lymphocyte depletion Hodgkin's disease and one from encephalopathy. Thirty children are disease-free, with the mean survival of 109.8 months.


Objective To investigate the association of human leukocytes antigen(HLA)-DR/DQ with oral lichen planus(OLP) in the area of Yangtze River Delta. Methods HLA-DRB1 and DQB1 genotyping of 44 unrelated OLP patients and 150 normal controls were performed by polymerase chain reaction-sequence specific primers(PCR-SSP) method.The data were compared between the OLP group and normal controls,and between different types of OLP patients. Results The frequency of HLA-DRB1*09 and HLA-DRB1*07 alleles were significantly higher in OLP group than those in normal controls(56.8% vs 31.3% and 27.3% vs 13.3%,P0.01 and P(0.05).) However,the frequency of HLA-DQB1*06 was significantly decreased in OLP group than that in normal controls((18.8%) vs 42.5%,P0.01).HLA-DRB1*04 allele was more frequent in OLP patients with erosive manifestation than those with reticular manifestatio1n(P0.05). Conclusion HLA-DRB1*09 and DRB1*07 are associated with the development of OLP in the area of Yangtze River Delta.HLA-DQB1*06 may be associated with the resistance to OLP,and HLA-DRB1*04 with the erosive manifestation of OLP.


Adequate situational awareness of pilots and reliable cyber secure data link between pilots and air traffic control staff are the main factors of the of aircraft flights safety. ADS-B technologies were designed as the most rational means to obtain situational awareness. The practical experience of ADS-B 1090ES system has proved its helplessness to provide either reliability or required air traffic security modern level. The effective solution to obtain adequate situational awareness, ADS-B cyber security and infrastructural autonomy is proposed using cryptographic means implementation as a self - organizing networking mechanism for ADS-B signals interchange. The cryptographic means should support public key algorithm for confidentially and authenticated network's common session key distribution and symmetric algorithm for ADS-B signals interchange in a broadcast mode.


The present criteria by which engineers are currently selected for managerial positions continually lead to a number of problems, not the least of which is the fact that engineers with technological training often find it difficult to appreciate the complexities of getting things done through other people, which is the essence of management. Research carried out at the Queensland Institute of Technology over a number of years indicates that the present methods of selecting engineers for managerial positions, indeed, the present method of selecting students to enter the engineering profession, are at best accidental and at worst could be totally ineffective. As a result of this research, it is argued that a far greater emphasis should now be placed on preferences in selecting people for technological and managerial positions. Currently, there is a great deal of emphasis on ability as a selection mechanism and is used to select students for the engineering profession as well as to select engineers to become managers. The matter of preference is seldom, if ever, taken into consideration. The method developed a t the Q.I.T., labelled Decision Perception Analysis, provides a mechanism whereby preferences can be taken into consideration in the selection process. Research over many years has shown that the use of this technique leads to: 1) higher job satisfaction 2) lower turnover; and, 3) higher productivity.


BCB(Bamboo Charcoal Bonded) grinding wheel is a new kind of grinding wheel developed by bamboo charcoal-phenolic resin composite for ELID(Electrolysis In-process Dressing) grinding technique. To study the affection of the ground workpiece surface roughness and removal rate with this new kind of grinding technique, the stainless steel SUS304 was ground using BCB grinding wheel in different machining parameters with ELID grinding condition, and the machining characteristics of BCB grinding wheel has been researched. The experimental results indicated that the ground workpiece surface roughness can be reached to Ra 0.010μm, and the efficient and precision machining with BCB grinding wheel by ELID grinding technique has been achieved for hard-to-cut materials. Finally, by studying of the grinding wheel surface condition and wear, the BCB grinding wheel grinding mechanism has been preliminary discussed.

Schistosomiasis is a neglected tropical disease. Sub-Saharan Africa accounts for 93% of the world's 207 million schistosomiasis cases. Urogenital schistosomiasis and malaria are both public health problems in Nigeria, where they are endemic. We determined the co-prevalence of urogenital schistosomiasis and malaria in schoolchildren and assessed its implication on anaemia and malnutrition. This cross-sectional study was conducted amongst primary schoolchildren in the Warwade, Saya Saya and Jigawar daha villages of Nigeria. Urine samples were collected to detect Schistosoma haematobium eggs, and finger prick blood was used for haemoglobin concentration and malaria diagnosis. Nutritional status was assessed using anthropometric measurements and a pre-tested questionnaire. The overall prevalence and density of S. haematobium were 27.7% and 9 eggs/10 mL, respectively, with significant differences between villages and sexes. The prevalence of malaria and infection density was 10.4% and 330 mps/μL, respectively. Co-infection prevalence was 3.3%. Anaemia prevalence was 66%, with significant variation across villages and between sexes. Prevalence of stunting, underweight, and wasting was 41.7%, 46%, and 29.7%, respectively. Mean haemoglobin concentrations in Plasmodium and children co-infected with urogenital schistosomiasis were significantly lower than those who were negative for the infection. No significant association was observed between malnutrition and single or co-infection of urogenital schistosomiasis and malaria. After adjusting for variables associated with anaemia, village of residence remained a significant predictor of anaemia. Water contact activities, such as fishing, swimming, and irrigation, emerged as independent risk factors of S. haematobium infection.


Modern Chinese architecture is complex in the form of architectural ideological trends. In these huge complex trends, campus buildings in the Republic of China are special treasures for their unique historical and cultural background of modern Chinese architecture. This article looks at four campuses from four different regions and explores the features of campus planning and architecture during the early age of the Republic of China. I hope this article will be helpful to future campus planning and new regional architecture for the 21st Century in China.


The nineteenth-century American literary marketplace is known to have been flooded with sentimental novels written by bestselling female writers such as Catharine Sedgwick, Fanny Fern, and E. D. E. N. Southworth (Tompkins, Newbury). A common feature they shared was a style of writing that awoke sympathy in middle-class women. One might ask nowadays whether Nathaniel Hawthorne (1804 64) imitated the style adopted by these female writers. If he did, he must have sympathized and identified with the heroic heroin [Hester in The Scarlet Letter (1850)] with an intensity comparable to the middle-class women readers and bestselling women writers of the day. To borrow a keyword from Lacanian psychoanalysis, female writers and Hawthorne both put their heroines (including, in Hawthorne's case, Hester Prynne of The Scarlet Letter) in a position of symbolic "lack" (a position where they are divested of phallic power) and then urged them to articulate themselves to gain status as speaking subjects. In fact, Hawthorne allows Hester to unfold a story in which the letter A she embroiders on her bosom may form the beginnings of a narrative where

Cold in-place recycling (CIR) of asphalt pavements is a process that has successfully been used for many years. The use of CIR for rehabilitation offers many advantages over traditional overlays due to its excellent resistance to reflective cracking and its environmentally friendly impacts. Despite the good performance and positive sustainability aspects of CIR, the structural contribution of the CIR base layer has not been well defined. In this research, CIR mixtures were designed with different asphalt emulsions. The mixtures were then subjected to dynamic modulus, repeated load triaxial, and flexural beam fatigue testing over a range of temperature and loading conditions. The performance test data generated were then used to develop CIR rutting and fatigue performance models used in the mechanistic analysis of flexible pavements. The technique used to develop the performance models leveraged the fact that the rutting and fatigue models for individual CIR mixtures were all within the 95 percent confidence interval of each other. A mechanistic analysis was conducted using the 3D-Move Mechanistic Analysis model. With the laboratory-developed performance models, the structural layer coefficient for the CIR base layer were developed for use in the 1993 AASHTO Guide for the Design of Pavement Structures. This analysis led to the determination of an average structural coefficient of the CIR base layer of 0.25.

Moderate-to-large earthquakes (M>6) frequently show clear rupture directivity. Recent studies revealed that a substantial percentage of small-sized earthquakes (M<∼5) display rupture directivity as well, owing to enhanced seismic monitoring. Is rupture directivity a common feature for earthquakes of all sizes? In this study, we investigated the rupture directivity of the 27 August 2021 ML 2.2 Gwangyang microearthquake that occurred at the southern tip of the Korean Peninsula by utilizing data from a recently expanded dense seismic network. The mainshock had two foreshocks and three aftershocks, which enabled us to define the fault plane from precise relative event locations and a well-constrained focal mechanism. Analysis of apparent source time functions obtained with the empirical Green's function technique reveals that the mainshock ruptured unilaterally toward the east. A detailed analysis of the source pulse leaving the focal sphere in 3D indicates that rupture directivity is consistent with the fault geometry and slip direction. Our study demonstrates that we can resolve rupture directivity of unilaterally rupturing microearthquakes (M<∼3) given adequate azimuthal coverage, and that this will lead to an improved understanding of the seismogenic processes in regions of low seismicity worldwide.


Transmit diversity generally requires more than one antenna at the transmitter. However, many wireless devices are limited by size or hardware complexity to one antenna. Recently, a new class of methods called cooperative communication has been proposed that enables single antenna mobiles in a multiuser environment to share their antennas and generate a virtual multiple-antenna transmitter that allows them to achieve transmit diversity. We propose a novel clustering structure for cooperative communication systems, whose objective is to increase the cellular network throughput and further improve the system performance. In this cellular system, we consider all the available users are divided into two groups. The super group is served by Base Station (BS), and the Mobile Stations (MSs) locate in the cell boundary are served by the clusterhead (CH) which is elect from the regular group. Simulation results show that this scheme can bring higher system throughput, and it also can increase the data rate at the cell edge.


Syphilis of the nervous system is undoubtedly a disease of common occurrence, but, as the general practitioner sees it, in the majority of instances it might be considered a rare as well as most formidable one—rare, for the reason that he does not recognize it; and formidable, because in its very nature it is such, and made more so through failure of proper recognition, permitting the stage of exudation to enter far into that of degeneration, long before the true character of the malady is brought to light. If we might be permitted to judge from our own observation, we would be led to say that in the vast majority of cases of syphilis of the nervous system coming under the observation of the general practitioner, it is not recognized until too late for the neurologist or syphilographer to do more than make a correct diagnosis or write a death


In the center of the corporate agricultural regime is the pesticide-industrial complex which is part of the current hegemonic order in the reproduction of capitalism. There are quasi-counterhegemonic movements, however, in the form of Integrated Pest Management and a fully counterhegemonic trend in the form of agroecology. Not only does agroecology as a science and practice eschew the use of pesticides in favor of biological controls developed by Latin American peasants over hundreds of years, but it has become a national and transnational movement led by La Vía Campesina (The Peasant Way) and agroecology has also become institutionalized on both of those levels. I consider cases from Latin America, with an emphasis on Mexico. JEL Classification: Q1, Q16, Q18, Q19


A study of diseases of the bovine lungs was carried out in Akwa Ibom State, Nigeria between (1999 – 2002). A total of 5,369 cattle were slaughtered within the study period out of which, 459 (8.5 %) lungs were condemned. Tuberculosis accounted for 183(39.921), representing 3.4 % of the total cattle population.  This was closely followed by Pneumonia, which was 180(39.2 %), representing 3.4 % of this population.  Abscesses, 93(20.1 %) and Taenia sp Cysts 3(0.7%), representing 1.7% and 0.1 % respectively of the total cattle population slaughtered also resulted in lung condemnations.  The overall annual prevalence of the diseases amongst condemned bovine lungs shows that most of them were encountered in the last three years of study, 10.1 %, 9.7 % and 8.7% for the years 2000, 2001 and 2002, respectively.  There was a clear positive seasonal influence on the prevalence of these diseases.  The prevalence rate of tuberculosis and abscesses decreased along the seasonal periods from LDS to EDS.  The rainy seasonal periods (ERS and LRS) increased the prevalence of pneumonia more than the dry periods while Taenia cysts were only recorded during the early dry season (EDS).  It was, therefore, concluded that tuberculosis and pneumonias, both accounting for over 79 %, were the major reasons for bovine lung condemnations at the abattoirs in Akwa Ibom State.


We describe a case of previously normal 22-month-old male who presented with vomiting, loose motions, lethargy, and seizures for 1 day. He had high anion gap metabolic acidosis, hyperglycemia, and ketosis managed elsewhere as diabetic ketoacidosis. Early management included hemodynamic stabilization, mechanical ventilation, correction of metabolic acidosis, seizure control, and later peritoneal dialysis. He was finally diagnosed with succinyl CoA 3 ketoacid transferase deficiency, a disorder of ketone metabolism usually presents with metabolic acidosis, ketosis, and hypoglycemia. Most cases present during the neonatal period (50%) and remain up to 20 months of age. The pathognomic finding is a nonspecific elevation on ketones in urine gas chromatography–mass spectrometry. Genomic sequencing is confirmatory.


Abstract Four sympatric and syntopic karyotype forms of Laetacara cf. dorsigera, centric fusion-originated were analyzed. Specimens with 2n=46, 2n=45, 2n=44 and 2n=43 chromosomes and differences with regard to the number of metacentric chromosomes, inversely proportional to their diploid number, were reported. Karyotypic formulae of the four cytotypes were: cytotype A=2M + 44A; cytotype B=3M + 42A; cytotype C=4M + 40A and cytotype D=5M + 38A and fundamental number constant (NF=48). Two centric fusion events are suggested: a) Robertsonian trans-location, which originated the first and second metacentric chromosomal pairs; b) isochromosome formed by the fusion of acrocentric homologous chromosomes in cytotypes with odd chromosomes. Genetic balance in the four karyotype forms of Laetacara cf. dorsigera seemed to have been determinant to their reproductive isolation. The presence of individuals with different karyotypic structures living in sympatry and syntopy and the absence of "intermediate individuals" (recombinants), that would have been expected in a panmitic population, permit one to conclude that probably form 4 cryptic species exist in the population.


"Irina Shchukina v Vladimir Lenin " was the title of a series of court room reports made by a renowned international journalist Yuri Kovalenko, the Izviestya newspaper correspondent in Paris. The series, published in spring 1993, reported the legal action of Irina Shchukina, heard by the Tribunal de Grande Instance, Paris. The defendants were three museums: The State Museum of Fine Arts (A. Pushkin Museum) in Moscow, the National Hermitage Museum in St. Petersburg and the Pompidou Centre Paris. This being so, the case, which concerned certain paintings on loan to the Pompidou Centre and displayed in an exhibition in Paris, also involved the Russian Federation. The title of the reports was, in my opinion, quite adequate, as the case concerned certain paintings of the French artist Henri Matisse which were part of the collection of Sergiey Ivanovich Shchukin a well-known Russian collector and art patron. That collection was nationalised on 28 October 1918, in a decree signed personally by V. I. Lenin. As I had the opportunity to take part in the preparations for the defending side, both in the hearing and in the trial itself, I would like to present some of the legal and other problems of the Shchukina v Lenin case. We should start by introducing the reader to the role played by S. I. Shchukin in the artistic and cultural life of Russia and to his real plans concerning his extraordinary collection of the works of French Impressionists.


The Leech lattice is a remarkable 24 dimensional Euclidean lattice with more than 8 10 18 symmetries. Suppose one is given two vectors in. Are they equivalent under one of these symmetries? We use the geometry of the lattice to produce an algorithm to answer this question quickly. Along the way we produce fast algorithms to detect whether two vectors in R 24 are equivalent under the action of one of the important subgroups M 24 and 2 12 :M 24 of Aut .

: "Untouchable" describes the friendship between two people of very different back-grounds, who are master and servant, but get along unexpectedly. Through the analysis of the friendship between the two in the film, this article aims to discover the friendship that touches the soul of human beings in the film: don't use the kindness you think to make the other person grateful.


Social Inclusion through the Digital Economy (SiDE) is a £12M project investigating how advanced technologies can be used to improve the lives of those from vulnerable groups including older people, disabled people, and marginalised youth. New digital technologies create the possibility of transforming the lives of those who find themselves in this position, but research is needed to realise that potential: this is the goal of SiDE. The talk will focus on how cloud computing is key to the solutions being explored, for example analysing accelerometer data to understand people's activity and thereby improve their health. The cloud research is based around e-Science Central - a portable, scalable, secure cloud platform. The talk will explain how the challenges of SiDE's applications have been addressed through the design of e-Science Central, including recent work on exploiting federated clouds to meet security and performance requirements. Based at Newcastle and Dundee Universities, SiDE is funded by RCUK through its Digital Economy programme.


In the wake of nationalist movements directed against the determination of The Netherlands not to give up their rights to West New Guinea, the Indonesian central government in 1958 nationalized Dutch properties, among them tobacco plantations.


Summary The leaf growth, carrying capacity and dairy production of four summer-growing pastures were measured in a subtropical area of Australia. The growing season was subdivided into ten 4-week periods and the production was estimated for each period. Carrying capacities were determined by rotationally grazing four paddocks of each pasture over the 4-week period, and varying the stocking density so that a target weight of leaf material remained on the pasture at the conclusion of each grazing. A non-limiting rate of nitrogen fertilizer increased total leaf production of kikuyu by 97% over a control treatment without nitrogen, but the response was not evenly distributed throughout the season. It fell to 50% during autumn when growth on the nitrogen-fertilized pastures was restricted following heavy defoliation during late summer. The use of the tropical legumes, siratro and glycine, in a mixed sward with kikuyu, did not increase leaf production over a kikuyu control pasture. The legumes grew poorly and this appeared to be due to the combined effects of their poor adaptability to the krasnozem soil, a high plant mortality especially during the first winter after sowing, the 4-week grazing interval and strong grass competition. The carrying capacity of the nitrogen-fertilized pasture was 1·3–5·3 cows/ha at the beginning (September–October) and end (April–mid June) of the growing season, and increased to a peak of 7·4–9·7 cows/ha during February-mid March. Nitrogen fertilizer increased the carrying capacity by an average of 131% over that on a kikuyu pasture without nitrogen. The carrying capacities were similar on kikuyu and on a mixed carpet grass-kikuyu pasture, both without nitrogen, but were less on a tropical legume-kikuyu pasture which was grazed at a lighter grazing intensity during autumn to aid legume persistence. Reflecting the experimental method of adjusting the stocking density according to the pasture available, differences in dairy production per cow were small relative to differences in the carrying capacity. Consequently seasonal variation in total dairy production/ha mirrored the carrying capacity. Nitrogen fertilizer increased the average production of 4% fat-corrected milk to 13·2 t/ha/40 weeks, an increase of 133% over the control without nitrogen. The results illustrate the marked seasonal imbalance in growth and carrying capacity for a given pasture, and emphasize the need to use mixed feeding systems to provide a uniform level of nutrition for a fixed number of cows.


This paper describes fuzzy cooperative coevolution adaptive control which uses a common genetic algorithm to obtain the coefficients of the adaptive fuzzy regulator. The plant under consideration is multi-mass drive system with elastic couplings. A comparison between systems with fuzzy control and conventional PID-control is considered. It is shown that fuzzy method allows to suppress torsional vibrations occurring at low speeds under the action of "dry friction" torque if there is only motor position encoder. The effectiveness of proposed algorithm is proved by simulation in MATLAB\Simulink and by the experimental results obtained on the real object.


Abstract : Intervisibility characteristics are critical to ground combat forces in shaping results of U.S. Army operational tests. An important question is: Are the results of a test conducted at a specific test site valid for a different deployment site? The thesis develops a methodology to help answer this question. It commences by tracing the background studies of intervisibility analysis, and then compares by computer simulation the intervisibility characteristics of several sites, and determine which sites are most nearly alike. Transformation equations are developed to facilitate extrapolation of certain continental United States (CONUS) test results to selected outside continental United States (OCONUS) sites.


Multi-layer dielectric devices used for isolated power transfer and suitable for high frequency power applications (>100kHz) are proposed. Such devices were realized based on a four terminal multi-layer ceramic structure with barium strontium titanate and alumina layers. Some key advantages of these devices are a reduction in losses over conventional decoupling techniques and ease of manufacturing due to the planar design. The paper focuses on the design details, characterization and performance of the Multi-Layer Capacitive Isolation Devices (MLCIDs).

The particles or droplets of an aerosol are usually charged or can be induced to acquire charge. This makes possible their manipulation by electric and, to some extent, by magnetic fields, not only when they are already fully grown, but also during the process of their formation or disappearance. In this manner their size, number, trajectories, form and site of deposition can be varied within wide limits. These principles have been applied in some cases and are obviously potentially applicable to a great many more. My own researches are concerned with the physics of combustion processes, where such methods can be used to act on dispersions of fuel, solid products or intermediates, but extrapolations to other fields readily suggest themselves.
