BAAI Island has a coastal forest formed from various communities and vegetation structures, which have functions including as a tourist area, a source of food, and disaster mitigation. The aim of this research was to find out the composition, structure and diversity of coastal vegetation on Baai Island area, west of Sumber Jaya Village, Kampung Melayu District, Bengkulu City. Sampling was taken using the transect line plot method with a size of 20 x 20 m for trees, 10 x 10 m for poles, a plot size of 5 x 5 m for saplings. The results showed that the composition of the coastal vegetation at the tree level found 11 families, with a total of 11 species. 5 species came from the pole level, and 4 species with a total of 11 individuals from the sapling level. The species of Casuarina equisetifolia obtained the highest value index of importance at the tree level, while the species Ardisia elliptica had the important value index for the stakes and saplings. The results of the calculation of the Shannon-Wiener diversity index (H'), of all growth levels show a value <1.0 which means low diversity, less stable.


The impact and generosity of these 'tunes' delivered in the face of animpending maritime disaster continue to fascinate, as does thenotion of playing whilst sinking, especially as the concomitant decisionto, in this case, make music, flies in the very face of a 'logicalpragmaticism'.2 Survivalist methodologies, and instinctual urgingsrelated to fight or flight, will always tend towards choosing to saveone's own life and/or, for the heroes amongst you, the lives of others.How do we then reconcile the decision to play 'cheerful tunes'?


Background: Albuminuria and left ventricular hypertrophy (LVH) are independent predictors of heart failure (HF), however, their combined effect on the risk of HF has not been explored previously. Objectives: To examine the joint associations of albuminuria and electrocardiographic (ECG) LVH with incident acute decompensated HF (ADHF), and whether albuminuria/LVH combinations modified the effects of blood pressure control strategy in reducing the risk of ADHF. Methods: 8,511 participants from the SPRINT (Systolic Blood Pressure Intervention Trial) were included. ECG-LVH was present if any of the following criteria: Cornell voltage, Cornell voltage product, or Sokolow Lyon were present. Albuminuria was defined as urine albumin-creatinine ratio (UACR) [≥]30 mg/g. ADHF was defined as hospitalization or emergency visit for ADHF. Cox proportional hazard models were used to examine the association of neither LVH, nor albuminuria (reference), either LVH or albuminuria, and both (LVH + albuminuria) with incident ADHF. Results: Over a median follow-up of 3.2 years, 182 cases of ADHF occurred. In adjusted models, concomitant albuminuria and LVH were associated with a higher risk of ADHF than either albuminuria or LVH in isolation (HR (95% CI): 4.95 (3.22-7.62), 2.04 (1.39-3.00), and 1.47 (0.93-2.32), respectively (additive interaction p=0.01). The effect of intensive blood pressure in decreasing ADHF attenuated among participants with co-existing albuminuria and LVH without any interaction between treatment group assignment and albuminuria/LVH categories (interaction p-value= 0.26). Conclusions: Albuminuria and LVH are additive predictors of ADHF. The effect of intensive blood pressure control in decreasing ADHF risk did not vary significantly across albuminuria/LVH combinations.


Abstract : This paper deals with the propagation of transient acoustic fields in waveguides that consist of a semi-infinite cylinder coupled to a resonant cavity or resonator. The walls of the waveguide are assumed to be rigid. The sources of the transient sound fields, or signals, are assumed to be localized in a bounded portion of the waveguide and to act for a finite interval of time. The goal of the work is to calculate such acoustic signals and to analyze how their structure depends on the sources and the geometry of the waveguide. Particular attention is given to the cases in which the signal sources or observation point, or both, lie in the cylinder and are far from the resonator. It is well known that in the cylindrical portion of the waveguide each signal can be decomposed into a series of modal waves. These waves are calculated and are shown to be asymptotically independent for large times.


Vigor testing of seed is surrounded by much confusion and contro versy. The confusion is mostly associated with the multitude of vigor tests developed and promoted during the past 25 years, the lack of workable definitions of seed vigor and vigor tests, and excessive vari ability in vigor test results and their interpretation. The controversy in seed vigor testing derives from the fear of some and the hope of others that vigor tests will become more widely recognized as a major means of establishing the planting value of seed, and permitted or required in seed labeling.

Abstract The burden of occupying the first established chair of business history at the. London School of Economics (and indeed the first in Britain) is happily lightened by the knowledge that the field is by no means as bereft of research and scholarship as this priority implies. The first two professors of economic history appointed at LSE fifty years ago, Eileen Power and R.H. Tawney, made distinguished contributions, to the study of medieval traders and to the impact of puritanism on the capitalist ethic. Their successors have maintained this interest in business history. T.S. Ashton's study of the business of Peter Stubs of Warrington was one of the building blocks from which his picture of the Industrial Revolution was built. Charlotte Erickson's study of British industrialists remains the classic account of their social and educational origins and career patterns between 1850 and 1950. Donald Coleman and Theo Barker, well before they joined with other scholars to found the Business History Unit, wr...


The degranulation of the C cells, their hypertrophy and hyperplasia leading to the formation adenoma-like nodules were observed under conditions of prolonged hypervitaminosis A which causes bone damage without associated hypercalcemia. These changes which are probably the morphologic manifestation of the increased requirement of the body for calcitonin, connected with the damage of the bone tissue seem to indicate that calcitonin is an important factor essential for the protection of skeleton from its excessive mineralization.


Thin plate splines,as an interpolating method which can be generalized to multidimensional space,is useful in surveying and mapping and many other subjects.According to the application it gives an algorithm adding nodes step by step to get thin plate splines.By using the technique of inverse matrix partly,this method can reduce the workload of calculation and can give the best choice of the least amount nodes on the request of precision.


The composition of volatile components in freshly-milled buckwheat flour produced from seed stored under controlled atmospheres (97% N 2 , 1.5% O 2 and 1.5% CO 2 ) for 1 year was studied using capillary gas chromatography, mass spectrometry, sniffing port analysis, and sensory evaluation. Twenty-five volatiles were identified from over 100 compounds removed from the flour by a novel dynamic headspace technique and separated by capillary gas chromatography. Eighteen odor-active regions were detected but none were characteristic of the typical buckwheat flour aroma. The concentration of the major buckwheat volatiles decreased with storage of the seed under low O 2 and high CO 2 levels. The content of two of the odor-active volatiles, hexyl acetate and 1-hexanol, however, increased up to 4 fold in samples stored under controlled atmosphere for 60 weeks.

This chapter explores the relationship of Onesimos' cup to the proverbs preserved in Plato and Theocritus. It shows how and why it is invoked by both the kylix and the literary passages. The chapter situates the superstition in the symposion, where spoken and written modes of communication vie with another, just as do textual and iconographical modes of commemoration in late archaic and early classical Greece. On the interior and exterior of the kylix both the names, Lykos and Erothemis , share the adjective kalos -in the erotic context of the symposion both men are honoured as handsome and sexually desirable-but that is the extent of their common characteristics. The chapter pursues the proverb further, exploring what it is about the figure of the wolf that lends itself to this superstitious notion, why it is the power of speech that is compromised, and in what particular ways becoming mute is a threat. Keywords: early classical Greece; iconographical modes; kalos ; lykos ; Onesimos' kylix


Abstract.In this paper, we start the classification of the dense near octagons of order (3, t). We shall determine all dense near octagons of order (3, t) with a big hex. In order to achieve this goal, we must also classify all spreads of symmetry of all dense near hexagons of order (3, t).


2=adhesive 3=interlayer 4=SentryGlas 5=temperature. Abstract The metal-to-glass bonding properties of an acrylate adhesive (DELO PHOTOBOND GB368) and an ionoplast interlayer (SentryGlas) have been investigated by a series of 'pull-out' tests, performed at 23, -20 and 60°C, on small glass laminates with a metal insertion. The specimens consisted of three layers of glass with a small stainless steel box section adhesively bonded or laminated in between. The test results showed a temperature dependency of both bonding systems.


We developed a battery-powered and AC-fed dual source EMU (test train) for the purpose of the interoperable service between the AC electrified lines and the non-electrified lines. The eveloped EMU is equipped with a 83-kWh lithium-ion battery system for traction. Thermal management of the battery is an important issue in ensuring long lifetime, and large input/output power. We developed a simple thermal network model to estimate the average temperature of battery cells. The running test results demonstrate that a deviation of the estimated battery temperature is acceptable value of up to 2°C both in summer and winter.

— Andhra Pradesh is one of the south Indian states in
India and having 13 districts. This is one of the most Covid-19
effected state in India during first and second waves. In India
district is the major administrative block for implementing
government policies and schemes under control of district
collector. So, estimating or forecasting trends in district level
more important than state wise or entire country wise. In this
paper we are proposing Susceptible, Exposed, Infected and
Recovered – Regression and Grid Search (SEIR-RGS) model
for analyzing Covid -19 district wise trends during second
wave. The SEIR-RGS, initially collects daily wise covid data
for each district from Department of Health, medical and
family welfare, AP and estimates the model parameters like
contact rate, incubation rate and recovery rate. To calculate
recovery rate the proposed model uses regression technique
between daily active cases vs cumulative recoveries. The
present model uses two phases for estimating contact rate and
incubation rate using grid search approach. After that the
proposed method calculates the infectious period, incubation
period and basic reproduction of infection in all 13 districts to
analyze trends in the state during second wave and also to
predict possibility of third wave in each district.

The causes of conflict among preschool children are well known. Much less is known about how preschool children act to protect the integrity of peer relations in the wake of conflict. Building on peace research on children and on nonhuman primates, this study demonstrates 2 complementary aspects of peacemaking among groups of European American preschoolers: peaceful associative outcomes to conflict ("together outcomes") and peaceful reunions between former opponents following a brief separation. The contexts in which conflicts occurred (inside classrooms and outside playgrounds) affected peacemaking, and so did the relationship of the opponents (friends vs. nonfriends). Other factors, such as the use of conciliatory behavior or aggression by opponents and the sex of opponents, were found to be associated with peacemaking. One of the single most important predictors of peacemaking was preconflict interaction between the opponents, illustrating our participants' general concern with the continuity and integ...

Cancer registration in Europe originated at the national level in the first half of the 20th century in Denmark. Since then, the process has undergone considerable expansion both in geographic terms as well as in its overall scope (from the basic initial incidence indicators to survival and clinical outcomes). Cancer registration is a key component of 'big data' in oncology and has become an important instrument for aetiological and epidemiological research at the population level.


Multi-homed wireless devices equipped with multiple network interfaces that support the Concurrent Multipath Transfer (CMT) of data are an inevitable part of future wireless networks. The Stream Control Transmission Protocol (SCTP) is a multi-homed transport layer protocol that can support CMT. However, the receiver buffer blocking issue causes throughput degradation and prevents CMT from realizing its vast potential over multi-hop wireless networks. This paper is focused on integrating network coding with SCTP-based CMT to resolve the receiver buffer blocking problem. We propose an adaptive network coding mechanism for SCTP-CMT to desensitize the receiver against packet reordering and consequently eliminate the receiver buffer blocking problem. Our state-of-the-art network coding scheme uses a Q-learning algorithm to control the number of redundant packets based on the network dynamics. The effectiveness and soundness of the proposed scheme is demonstrated through simulations and proved to outperform original SCTP-CMT up to a factor of 62% in the presence of severe path dissimilarities and limited receiver buffer. Our proposed scheme is one step forward towards future multi-homed devices over multi-hop wireless networks.


In order to understand failure cause and stress analysis, strength evaluation of joints and non-destructive test were done for brazing joint of copper pipe in household air conditioner. Strength of brazing joint was evaluated by shear test and test specimens were used by standard single lap form and actual form of brazing joint in copper pipe. In order to evaluate the effect where the temperature has an influenced on the joint during this brazing joint processing, micro vickers hardness is measured. Also, three dimensional X-ray non-destructive test was used to know defect existence of brazing joint. Internal pressure breaking tester was designed and was performed to make higher oil pressure by specific ratio within the interval of time.


As mouse cancer models continue to more accurately depict the human disease, the ability to detect and monitor tumor development and regression has become increasingly important. Recent developments in microimaging techniques now offer researchers the ability to accurately detect and monitor tumors less than a millimeter in diameter in live mouse models. Introduced commercially in 2000, micro–computed tomography (CT) scanners are now capable of scanning live mice with spatial resolution exceeding 20 µm. Although X-ray computed tomography provides exquisite skeletal images due to the inherent high density of bone, this chapter is intended to provide an overview of microCT imaging of mouse cancer models, including soft-tissue tumors, which are particularly challenging. A further goal is to highlight the strengths and expose the weaknesses of this amazing new technology.

The concentration of Se in algal cells is a primary determinant of Se tissue contents in higher level consumers. Differences in the ability of algal species to concentrate selenite and vari- ability in ambient selenite concentrations may be important determinants of algal Se contents. We compared uptake of 75 Se-labeled selenite by 14 algal species at 2 environmentally relevant selenite concentrations. Se content per unit cell volume (Se/Vc) varied by almost 4 orders of magnitude when algae were exposed to 4.5 nM selenite and almost 5 orders of magnitude when exposed to 0.15 nM selenite. Chlorophytes typically exhibited the lowest Se enrichments, while prymnesiophytes, prasinophytes and dinoflagellates exhibited the highest. The Se/Vc of diatoms and cryptophytes var- ied by >2 orders of magnitude. Even at the lowest selenite concentration, about half the species con- centrated Se to an extent that might cause toxicity at higher trophic levels. Within species, the Se cell concentration typically varied by only 2- to 3-fold when exposed to selenite concentrations that dif- fered by 30-fold. The Se cell concentration of only 1 species, the diatom Skeletonema costatum, var- ied in proportion to ambient selenite concentrations. A more detailed study of the dependence between Se cell concentration on ambient selenite concentrations in the diatom Thalassiosira pseudonana revealed an asymptotic approach to a maximum Se cell concentration at high ambient selenite concentrations (> 0.1 nM). Given the results for other species exposed to 4.5 and 0.15 nM selenite, such saturation is likely to be a common feature. Our results indicate that the composition of the phytoplankton community could have a pronounced impact on Se concentrations in marine food webs.


It is impossible to imagine now modern solid-state physics without semiconductor heterostructures. Semiconductor heterostructures and, particularly, double heterostructures, including quantum wells, wires, and dots, are today the subject of research of two-thirds of the semiconductor physics community. The ability to control the type of conductivity of a semiconductor material by doping with various impurities and the idea of injecting nonequilibrium charge carriers could be said to be the seeds from which semiconductor electronics developed. Heterostructures developed from these beginnings, making it possible to solve the considerably more general problem of controlling the fundamental parameters inside the semiconductor crystals and devices: band gaps, effective masses of the charge carriers and the mobilities, refractive indices, electron energy spectrum, etc. Development of the physics and technology of semiconductor heterostructures has resulted in remarkable changes in our everyday life. Heterostructure electronics are widely used in many areas of human civilization. It is hardly possible to imagine our recent life without double heterostructure (DHS) laser-based telecommunication systems, heterostructure-based light-emitting diodes (LED's), heterostructure bipolar transistors, or lownoise high-electron-mobility transistors for highfrequency applications including, for example, satellite television. Double-heterostructure lasers now enter practically every house with CD players. Heterostructure solar cells have been widely used for space and terrestrial applications. Our interest in semiconductor heterostructures was not occasional. Systematic studies of semiconductors were started in the early 1930s at the Physico-Technical Institute under the direct leadership of its founder, Abraham Ioffe. V. P. Zhuze and B. V. Kurchatov studied the intrinsic and impurity conductivity of semiconductors in 1932, and the same year Ioffe and Ya. I. Frenkel created a theory of rectification in a metalsemiconductor contact based on the tunneling phenom-


We present two transforms of non-conformal harmonic maps from a surface into the 3-sphere. With these transforms one can construct from one non-conformal harmonic map a sequence of non-conformal harmonic maps. We also discuss the correspondence between non-conformal harmonic maps into the 3-sphere, H-surfaces in Euclidean 3-space and almost complex surfaces in the nearly Kahler manifold S3 × S3.


Understanding the relationship between workplace environment and behavior is an important concern for designers. We report on a pilot study where ubiquitous computing was used to examine workplace activity quality in a commercially designed workplace environment. Data were collected from twelve adult participants in the same professional workplace, for twenty-one workdays during one month. The data collection system was composed of small wireless infrared motion sensors, a Bluetooth-based positioning system using mobile phones, and a context-sensitive self-report survey administered on the mobile phones. Participants were automatically queried about their work practices and their environment via these mobile phones, every time they changed their locations in the workplace. Questions were also asked during the remainder of the day, albeit less frequently. We describe how software visualization tools were developed to visualize the data collected during the experiment, and we report on some of the attributes of subjects' behaviors that can be observed using the tools. Implications of these results with respect to research methods and enabled design methods are discussed. Thesis Supervisor: Kent Larson Title: Principal Research Scientist

Abstract : New control algorithms were developed for robust stabilization of nonlinear dynamical systems. Novel, linear matrix inequality-based synthesis algorithms were developed for the anti-windup problem. Results were extended so that they are applicable to all stabilizable linear systems with input saturation. New insights into the closed-loop behavior of model predictive control were discovered. It was shown that certain model predictive control algorithms induce stability without any robustness. Then it was shown how these algorithms can be modified to guarantee robustness. Formulas for horizon length to guarantee robust stabilization were given, and in the process it was shown that many of the standard assumptions in model predictive control could be relaxed. Extremum seeking control algorithms were advanced, and developed for systems with constraints and with nonsmooth response maps. Finally, some initial progress was made on the use of logical elements in nonlinear control algorithms and the understanding of hybrid control systems in general.


Abstract While the contemporary systemic model of neighborhood crime has emphasized the regulatory capacities that are imbedded in the structures of local community relational networks, very little attention has been paid to the dynamics of social control that are exercised through these linkages. This is a very important consideration, given recent reformulations of this framework as a multilevel model. This paper suggests that the social capital model of James Coleman (1990) can serve as an excellent theoretical basis for such an extension and examines the degree to which neighborhood networks serve as mechanisms of social control for a sample of Oklahoma City residents. Evidence is provided that while the degrees of integration into private and parochial neighborhood-based networks have the expected associations with susceptibility to social control, this is not the case for more general friendship and family relational structures.


New identities appearing from consideration of higher genus characters for generalized vertex operator algebras with a formal VOSA parameter associated to a local coordinate on a self-sewn Riemann surface are considered. Genus two version of twisted product Jacobi identity is reviewed. Further generalization of classical number theory identities for modular forms are proposed. 2010 Mathematics Subject Classification: 17B69; 30F10; 32A25; 11F03


Molecular dynamics has been used to establish parameters for effective site-site pair potentials for liquid CCl2F2 and for liquid CHClF2. The parameters were chosen so that the calculated and the experimental values of the pressure and energy agree for liquid states on the liquid-vapour coexistence curve. The structural features predicted by these potentials are similar to those found in simulations of other halogenated methanes.

This paper is concerned with the problem of delay-dependent H∞ control of discrete-time uncertain recurrent neural networks with time-varying delays. The neural network is subject to parameter uncertainty, and time-varying delay. For the robust H∞ stabilization problem, a state feedback controller is designed to ensure the global robust stability of the closed-loop system about its equilibrium point for all admissible uncertainties. By using the Laypunov-Krasovskii functional, a linear matrix inequality (LMI) approach is developed to establish sufficient conditions. A simulation example is exploited to show the usefulness of the derived LMI-based stability conditions.


The production efficiency of water and nitrogen is affected by irrigation and the nitrogen rate. However, it is unclear whether there is a coupling effect of irrigation mode and the timing of nitrogen fertilizer application on rice. Therefore, a two‐year field experiment was conducted at two sites with varying cumulative temperatures from 2018 to 2019. The effects of irrigation mode and nitrogen fertilization timing on rice yield and related physiological parameters were examined in different regions. The results showed that sites with different average temperatures had different coupling effects of water and nitrogen on crop growth. The impact of irrigation mode on yield was greater than that of nitrogen fertilizer timing at the site with a 2800 °C annual cumulative temperature (Wanchang). Alternate wetting and drying irrigation increased yield, water production efficiency and nitrogen production efficiency by 8%–10%, 31%–37% and 8%–10%, respectively. In the site with a 2500 °C annual cumulative temperature (Longjing), the coupling effect of irrigation method and nitrogen fertilization timing was significant, and continuously flooded irrigation combined with nitrogen fertilizer (40%:30%:20%:10%) improved rice yield and production efficiency by delaying senescence of leaves and increasing dry matter translocation. The results indicate that combining temperature to explore the optimal coupling mode of irrigation and nitrogen is a promising cropping technique to improve crop productivity and production efficiency in northeastern China.


Author(s): Mirsky, Ethan | Advisor(s): Voigt, Christopher | Abstract: Bacteria naturally contain a wide variety of multi-component molecular machines that perform complex functions such as chemotaxis, photosynthesis, chemical fixation, and protein secretion, all of which are potentially valuable to synthetic biologists for use in engineered organisms. However, in most cases, the gene clusters encoding these functions are complex and intricately regulated by the bacteria, making them difficult to reuse for new applications.One potential method to address these difficulties is refactoring: a process of recoding the genes for the purpose of simplification and re-use. Here, we present the methods, techniques and results of refactoring the Salmonella Pathogenicity Island I (SPI-1) Type III Secretion System (T3SS). The SPI-1 T3SS is used naturally by Salmonella to inject pathogenic effector agents into its host cell and, unlike the most commonly used secretion mechanisms in bacteria, is capable of transporting functional proteins through both membranes of the bacteria directly into the culture media. This function may enable such biotech applications as targeted peptide/drug delivery and continuous protein expression. In addition, the methods developed here should be broadly applicable to a wide range of bacterial gene-clusters.


Two quite different types of microstructures have been detected for MgTiO_3-enriched LiTaO_3 ceramics corresponding either to small size grains and open porosity or to large size grains with closed porosity and appearance of microcracks. The first structure appears in short sintering processes at relatively low temperature. The textural change is explained by transitory formation of a grain boundary phase that leads to quick coalescence of the small grains.

The climax of the production's comic indulgence surrounded Dr Pinch who entered in mad wig and hat and attached two metal caps to master and servant from the top of which waggled spiral antennae. From a control box on his chest he passed an electric shock through them and they went into seizure along with anyone with whom they happened to be holding hands; at one point a spasm ran through the whole company. The production chased through the denouement and the Abbess's festive mention of the calendars of their nativity left us with the sense of the production as a panto romp. Its breakneck pace and fluent lightheartedness underlined the script's dramatic competence. It is such confident and comedic productions which do more than any other to require that we re-evaluate such traditionally 'minor' works. P.J. S.


The study assessed, from survey, the influence of human resource management practice as it relates to employees' job performance in some Federal university libraries in the six geo-political zones of Nigeria. Stratified random sampling technique was employed to come up with six universities from each of the six zones. The researchers administered 7 copies of questionnaire each in the study areas to elicit data on the employees' job performance. A total of 42 copies of questionnaire were administered and retrieved (100% response rate). The data collected were analysed descriptively and inferentially. The null hypothesis was tested using Kruskal Wallis statistical method. The descriptive analysis result showed that majority of the libraries studied reported that human resources management practices influenced their employees' job performance. Inferentially, the human resources management practices have significantly influenced their staff performances. The study recommended that Federal University libraries should operate uniform human resources management practices policy enhance staff productivity, effectiveness and efficiency in their work places.

RESULTS: The PEM exceeded the minimum rate of 80% agreement between professionals and patient evaluators. A professional in the linguistic area also evaluated the developed material, concluding that the instrument is understandable by people who studied up to the fifth year of elementary school. The format and layout of the texts and figures were considered pleasant by the interviewed patients. CONCLUSION: The PEM was developed and validated with adequate information, from the professional point of view and according to the needs of the patients, and it can constitute a useful auxiliary tool for patients during periodontal treatment.


Spectrophotometric, chromatographic, polarographic and microanalytical evidence is presented for the identity of the calcium reagents, calcion and calcichrome. The polarographic data favour a bis-azo structure for the compound.


Propeller wake wash phenomena were investigated as a means of clearing pack ice, as used during ice breaking and ice management operations. Experiments were performed to model the propeller wash and data were collected to quantify the capacity of a propeller to clear pack ice under a range of operating and environmental conditions. The work focused on the interaction between operating and environmental conditions using a central composite experiment design with four factors: propeller shaft speed, declination angle, initial ice concentration, and distance to the ice edge. It was found that the propeller shaft speed was the most significant factor and that increasing propeller rotation speed increased ice clearing most effectively. To clear ice far downstream of the propeller, it was found that directing the propeller wash at the water's surface imparts more energy to the ice pieces, causing them to travel farther.


The surface structures of the (quasi-)one-dimensional reconstructions induced by the adsorption of Eu on Si(111) have been investigated by low-energy electron diffraction (LEED) and high-resolution ...


ABSTRACT The Swedish population is one of the oldest in the world with the consequence that the country has a very high proportion of long-term institutional beds to meet the care needs of elderly people. Studies of the pathways to institutional care showed that alternative home care options had been given too little consideration and that a quarter of residents could have been satisfactorily supported in the community. The Sundsvall Intervention Programme was based upon a distribution of these research findings to institutions and practitioners, followed by a joint training programme on assessment and resource allocation. The first phase of the intervention yielded an unrealised potential for elderly people to remain at home; but it met continuing resistance from professionals and kin. The exercise indicates the need to combine service innovation with locally relevant systems which engage all of the interested parties – elderly people, their relatives, care providers, service managers and politicians.


A simple, effective data hiding method based on module substitution is proposed. A variety of confidential bits are embedded to each block in accordance with the base-value of the block. In addition, two fine-labeling procedures are employed in the proposed method to further alleviate the quantized error during data embedment. Simulations show that both PSNR and hiding rate generated by the proposed method are better than those generated by the reported methods. Since the perceived quality of the resulting mixed images is good, the hackers are hardly noticed the existence of the secret message.


ABSTRACT This article describes a quality assessment of the processes underlying municipal mobility policy-making in Flanders, Belgium. 25 criteria and 176 aspects were queried during 25 interview sessions. Results were aggregated at the level of 7 quality domains of action and suggest that Flemish municipal mobility policy-making is generally fairly frail and of an ad-hoc nature. Four factors are found to be determining for this finding: default of political continuity, internal conflicts between stakeholders, lacking internal expertise, and deficient financial resources. Inter-stakeholder collaboration, residents' participation, and policy-integration with higher-level programs are the strengths of current mobility policy practices in Flanders.


AISI M4 and CPM15V are used as tool steels since they have high hardness and wear resistance. This study is concerned with die and mold hardfacing using laser melting deposition with M4 and CPM15V powders. For this purpose, the two types of metal powders were deposited on SKD11 base metal, and the microstructures, hardness and wear resistance of the deposited materials were compared. During processing, substrate preheating was used to reduce the degree of thermal deformation and prevent crack formation. Based on the preliminary experiments, the process conditions were established. As a result of observing of the microstructure, columnar and cellular dendrites were observed in the M4 deposited layer. Using EDS analysis, the carbides precipitated along grain boundaries were identified to be M6C/M23C6 carbides with a high content of molybdenum and tungsten. On the other hand, no dendritic microstructures were observed in the CPM15V deposited layer, and metastable austenite, martensite, and M8C7 carbides were formed. A large amount of fine carbide was found to have a high content of vanadium and chromium. The M4 and CPM 15V deposited regions had average hardnesses of 815 and 897 HV, respectively. The ball-on-disc test results showed that the deposited CPM15V had better wear resistance than that of the M4 deposited. These results are attributed to high martensite fraction, and the types and sizes of carbides of the deposited CPM15V. (Received February 12, 2018; Accepted April 16, 2018)


Over twenty years ago in the shadows of an architectural conference in the USA several of us from outside the American/European axis left early, finding the mainstream presentations and discussions boring, predictable and stuck in the ruts of well-worn paths. We were aware that in the wider world genuinely new ideas were emerging with rich traditions at play, altogether less constrained by self-conscious architectural production. We were keen to find a name for these new approaches emerging across latitudes below the Tropic of Cancer and settled on "South of Cancer" as a suitable catch-all for these diverse tendencies.


We prove that the Gaussian parity on free two-dimensional knots is universal. Introduction A parity is a rule to assign labels 0 and 1 to the crossings of knot diagrams in a way compatible with Reidemeister moves (Fig. 1). It was introduced by V.O. Manturov [6] in his researches concerning free knots.


Objective To investigate the effect of different Chinese herbs on cell proliferation and cartilage oligomeric matrix protein(COMP)expression in chondrocyte culture.Methods Chondrocytes isolated from rabbit knee cartilage were cultured for 3 generations with the density of 2×10~4/cm~2 and were verified by collagenⅡimmunohistochemical staining.Rabbit sera containing herbs were obtained after animals orally ad- ministrated herbs at the dosage equivalent to human.At 5% and 10% serum density,cells were cultured in the medium that contained liver-softening herbal compound sera.Subgroups setting at 1,3 and 5 hours after herb intervention were observed.Rabbit and bovine sera were control groups.Seven days after intervention,chon- drocytes proliferation was observed using the MTT assay kit.For the study of COMP expression,chondrocytes were isolated from human knee cartilage supematant.Superuatant COMP level was tested by enzyme-linked immunoabsorbent assays(ELISA)after directly adding compound and extract from liver-softening herbs to the culture at the final concentration of 10 mg/ml for 3 days.Results Liver-softening herbal compound group had significant effect on cell proliferation compared to control,of which,3-hour subgroup was more significant than 1-and 5-hour subgroups(P0.05).COMP level in both extract and compound liver-softening herb groups was higher than control(P0.05),but no significant difference was demonstrated between extract and com- pound groups.Conclusion The finding suggests that serum containing liver-softening herbs can stimulate cell proliferation.When added directly to cultures,both extract and compound liver-softening herb can promote COMP expression of chondrocyte in vitro.


Context: Candidemia is a major cause of nosocomial morbidity and mortality in neonates. Although Candida albicans remains the most common fungal isolate from blood, longitudinal studies have detected a trend toward an increased prevalence of other Candida species. Aims: To study the changing pattern of candida species and their importance in bloodstream infection in neonates. Settings and Design: This is the 3-year respective study. Subjects and Methods: The neonates born or admitted during Jan 2010-Dec 2012 were included in the study. A total of 69 neonates with Candidemia as evidenced by positive blood cultures were considered. Peripheral blood samples were collected for culture, isolation and identification of Candida species by bacT/alert automated system, germ tube test and Vitek 2 cards for yeast identification. All the isolates were checked for purity and speciated by Chromagar. Statistical Analysis Used: No. Results: A total of 7.48% neonates had Candidemia. Non-albicans Candida was found in 85.5% of neonates while Candida albicans was found in only 14.5% neonates. Candida tropicalis (42%) was the predominant non-albicans Candida species isolated in our setting followed by Candida krusei (38%). Conclusion: There are multiple risk factors that are responsible for emergence of neonatal Candidemia in recent years. In conclusion, non-albicans Candida species are assuming an increasing role in nosocomial infections in neonates and finding of this study highlights the increased isolation of Candida tropicalis in our setting. The study emphasizes the identification of candida species to reduce morbidity and mortalities in the neonates.


Background: The remarkable properties of nickel oxide (NiO) and cerium oxide (CeO2) nanostructures have attracted considerable interest in these nanocomposites as potential electroactive materials for sensor construction. Methods: The mebeverine hydrochloride (MBHCl) content of commercial formulations was determined in this study using a unique factionalized CeO2/NiO-nanocomposite-coated membrane sensor. Results: Mebeverine-phosphotungstate (MB-PT) was prepared by adding phosphotungstic acid to mebeverine hydrochloride and mixing with a polymeric matrix (polyvinyl chloride, PVC) and plasticizing agent o-nitrophenyl octyl ether. The new suggested sensor showed an excellent linear detection range of the selected analyte at 1.0 × 10−8–1.0 × 10−2 mol L−1 with regression equation EmV = (−29.429 ± 0.2) log [MB] + 347.86. However, the unfunctionalized sensor MB–PT displayed less linearity at 1.0 × 10−5–1.0 × 10−2 mol L−1 drug solution with regression equation EmV = (−26.603 ± 0.5) log [MB] + 256.81. By considering a number of factors, the applicability and validity of the suggested potentiometric system were improved following the rules of analytical methodological requirements. Conclusion: The created potentiometric technique worked well for determining MB in bulk substance and in medical commercial samples.


Bifunctional catalysts based on platinum and amorphous silica-alumina were studied in the hydroconversion of n-hexadecane. The influence of platinum loading and support acidity on activity and selectivity were assessed. The contribution of hydrogenolysis reactions on top of bifunctional hydrocracking was shown to depend not only on metal loading, but also on the effect of support acidity on the intrinsic activity of the platinum sites. The yield of cracking products, and their linear alkane fraction, increased with metal loading, while the isomerization yield was practically independent of the metal content. On a support of high Bronsted acidity, the rate of formation of methane was proportional to the platinum surface area, indicating that dernethylation occurred by metal-cataly ed hydrogenolysis. On the other hand, the methane site-time yield was one order of magnitude lower on a catalyst with negligible Bronsted acidity. Pt-catalyzed hydrogenolysis was also investigated during selective poisoning of acid sites by cofeeding pyridine and comparing the effect of hydrogen partial pressure on reaction rates. In the presence of pyridine, total hydroconversion activity was reduced by one order of magnitude while rates to methane and linear cracking products remained relatively high. These observations indicate that acid sites do not intervene in the mechanism, but that support acidity affects the hydrogenolytic activity of platinum sites.


Many tasks in computer vision rely on accurate detection and matching of visual landmarks (e.g. image corners) between two images. In particular, for the calculation of epipolar geometry from a minimal set of five correspondences the spatial accuracy of matched landmarks is critical because the result is very sensitive to errors. The most common way of improving the accuracy is to calculate a sub-pixel location independently for each landmark in the hope that this reduces the re-projection error of the point in space to which they refer. This paper presents a method for refining the coordinates of correspondences directly. Thus given some coordinates in the first image, our goal is to maximise the accuracy of the estimate of the coordinates in second image corresponding to the same real world point without being too concerned about which real world point is being matched. We show how this can be achieved as a frequency domain optimisation between two image patches to refine the correspondence by estimating affine parameters. We select the correct frequency range for optimisation by identifying a direct relationship between the Gabor phase based approach and the frequency response of a patch. Further, we show how parametric estimation can be made accurate by operating in the frequency domain. Finally, we present experiments which demonstrate the accuracy of this approach, its robustness to changes in scale and orientation and its superior performance by comparison to other sub-pixel methods.


The refined similarity hypothesis of Kolmogorov [J. Fluid Mech. 13, 82 (1962)] is extended to a scalar field. These hypotheses are tested using measurements in a circular jet and the atmospheric surface layer. Over a significant part of the inertial range, statistics of the normalized stochastic variables for velocity and temperature indicate a dependence on the separation r. This dependence is also quantified through the probability density functions of the stochastic variables and the correlation between the velocity (or temperature) increment and the local energy (or temperature) dissipation rates. Probability density functions of the stochastic variables are conditioned on the local Reynolds number Rer based on r and the local energy dissipation rate. These functions depend on Rer when the latter is small and are approximately universal when Rer is very large. This behaviour is consistent with the refined similarity hypothesis. There is however a slight difference between the shapes of the conditional...


An alkaline hydrogen peroxide oxidation of chalcones with methoxymethoxyl groups in the 2′-position and in other positions gave the corresponding poly(methoxymethoxy)chalcone oxides; these were then, in turn, easily converted into polyhydroxydihydroflavonols, with a simultaneous splitting of all the O-methoxymethyl groups, by warming with acid. The general applicability of the new method was illustrated by the synthesis of the following hydroxydihydroflavonols: 3,7-dihydroxy- (m.p. 170–171°C),3,4′-dihydroxy- (m.p. 214–216°C),3,4′-dihydroxy-3′-methoxy- (m.p. 217–218°C),3,4′,7-trihydroxy- (m.p. 214–215°C), and 3,3′,4′,7-tetra-hydroxyflavanone (dl-fustin, m. p. 217–218°C). The first four new compounds were identified by converting them into known methyl ethers, while the last one was identified by comparing it with natural dl-fustin. Their structures were also confirmed by infrared and ultraviolet spectra.


I H E I HE PERIOD BETWEEN the close of World War I and the crash of the stock market in 1929 was a time of far-reaching political and social change in Canadian life. The government was forced to respond to the problems of the returned soldiers, and many believed its response inadequate. Rural disenchantment with post-war political leadership caused a major shift in the traditional centres of power from east to west and from industry to agriculture. Nonetheless, industries and cities continued to grow, fed by cheap immigrant labour, and the industrial labour force demanded higher wages and better working conditions. Nineteenth-century reform movements reached a height in the "social passion" of the twenties, and a Communist party was formed in Canada. Moreover, Canadian political autonomy was established firmly during the decade and British control over Canadian legislation effectively ended in 1931. Despite these dramatic social changes the dominant form of fiction during the twenties continued to be the rural romance, escapist literature which ignored the contemporary social situation. Realism, an ideal medium for the objective reporting of social phenomena, had still not made its way into Canadian fiction in the early decades of the twentieth century. Continental literary realists had rebelled in the nineteenth century against the notion that the essence of experience was unknowable because it existed in a reality closed to sense perception. They had chosen to make the commonplace and the ordinary respectable subject matter for the novel. Describing a universe governed by material cause-and-effect required a technique which involved close observation of the details of everyday life, and the resulting record had not only to give the impression of mass social behaviour but also to explain the interplay between society and the individual. Flaubert, Zola, the Russian realists and others evoked middle-class settings and objectively revealed the folly of romantic passion, and naturalism explained the "lower depths" of life by a negative determinism. Grove's The Master Mason's House (published in 1906 as Mauermeister I hies Haus) indicates an awareness of naturalistic developments in the French novel.


Today the independent component analysis (ICA) has been widely used in the blind source separation (BSS) to separate independent components in a data set based on its statistical properties. However, when the dimension of the input data is too high, the performance of the ICA may be not satisfactory. To address this problem, the present paper has proposed the new integrated method for the independent component extraction. The supervised manifold learning was firstly adopted to reduce the dimension of the input data, and then the kernel ICA (KICA) was employed to extract useful independent components in an efficient manner. The application of the proposed method has been successfully applied to the face image recognition. The experimental analysis has showed satisfactory and effective face image identification performance.


A review of the approach to the study of turbulence (spatiotemporal chaos) in a finite spatial region, based on decomposition of the underlying partial differential equations over an infinite set of modes and subsequent truncation of the infinite chain of the corresponding ordinary differential equations (ODEs), is given. The review starts with a general survey of this approach. Then, to illustrate it in terms of real systems, two recently studied models are considered in some detail. The first model is a system of six ODEs for amplitudes of eigenmodes of the curl operator, which is a simplest nontrivial truncation of the three-dimensional (3D) Euler equations; the wave vectors of the six modes are closed into a simplex (tetrahedron) in the 3D space, which makes this truncation basis very natural. The resultant dynamical system (DS) has three integrals of motion, that can be interpreted as the energy, helicity, and squared angular momentum of the flow. Depending on values of these conserved quantities, nu...


Hierarchical nanostructured Co-doped WO3 with carbon as template has been successfully synthesised through facile sol-gel method. The synthesised Co-doped WO3 was characterized by X-ray diffraction, Scanning electron microscopy, Transmission electron microscopy, Energy dispersive X-ray spectrometry, and Brunauer-Emmett-Teller and X-ray photoelectron spectroscopy. The gas sensing properties of WO3 doped with Co from 0 to 0.8 wt % were also investigated on various VOCs. The fabricated sensor based on 0.6 wt% Co-doped WO3 with carbon as a template showed good sensitivity, selectivity, fast response and recovery time towards 1.5 ppm of acetone at 50 °C under 90% relative humidity. The excellent gas sensing properties could be attributed to high surface area, small crystallite size, defect of WO3 and Co catalysis effect which promotes gas adsorption and most importantly the stabilized monoclinic phase of WO3, which accounts for the good selectivity.


With the explosive growth of high‐data rate multimedia services and machine‐to‐machine (M2M) type communications, numerous small cells will be densely deployed in future fifth generation wireless network, resulting in serious interference, intolerable delay, and huge handover failure. Massive access M2M services, with low‐rate high‐frequency requests, will also generate much signaling overhead costs and cause enormous waste of system resources. In the Third Generation Partnership Project, the split of control and user (C/U) planes is perceived as one of the most promising methods for small cell enhancement to address these challenges. In this article, a new C/U split architecture of data‐only carrier (DoC) system is analyzed comprehensively from various aspects, such as overhead costs, coverage probability, spectral efficiency, and energy efficiency for the first time. Based on the model of stochastic geometry, the influences of density and power of small cell and cell range expansion factors are all taken into account to compare the DoC architecture with the baseline long‐term evolution (LTE) system. Numerical results show that the DoC system can greatly reduce the overhead costs and help to achieve higher throughput gain and better coverage performance over the conventional LTE system.

Background: With increasing age agility starts declining. Use of an assistive device hopefully aids in improving balance, agility, and confidence. There are fewer studies of objective quantification of agility with the use of the assistive device. This study aims to determine the agility in elderly using an assistive device by 8 foot up and go test. Methods: A comparative, experimental study was done on 60 Healthy adults of age 75 to 85 years. Subjects were asked to perform 8 foot up and go agility test initially without assistive device and then with an assistive device. The time in seconds was noted respectively. The mean of the two trials each was calculated. The data were analyzed using the paired t-test. Results: There was a statistically significant difference in mean agility score on 8 foot up and go test between subjects without an assistive device (12.33 ± 3.21 seconds) and with an assistive device (13.33 ± 3.39 seconds). Subjects when given assistive device took a longer time to complete the 8 foot up and go agility test than they required for completing it without an assistive device. Conclusion: There was a significant decrease in agility in elderly using an assistive device as shown by the increase in time taken to complete the 8 foot up and go agility test. There is a need for cautious clinical prescription practice for mobility aids.

«Several Legal Concepts Of Civil Law About Housing». The Civil Code and special legislation attempt to meet housing needs. As well as purchasing a property, there are legal concepts, such as the right of habitation (Property Law), residential letting and its forms of assignment and subletting, free loan (Contract Law) or the assignment of the use of the family residence to one of the parents or children (Family Law). The requirements and effects of these concepts are investigated in order to take advantage of their opportunities and to detect abuses.


Three synthetic methods have been developed for embedding nanosize metal particles into polymers: (i) in situ synthesis of colloidal silver in cross-linked poly(acrylamide) gels, (ii) implantation of cryochemically produced silver nanoparticles into poly(acrylamide) gels, and (iii) encapsulation of metal nanoparticles in poly(p-xylylene) films. All methods allow one to produce 3-20 nm stable clusters embedded into bulk materials, thin films or fine metal-polymer particles dispersed in organic solvents. Some physical properties of the metal-polymer systems are discussed.


From the late 19th century to the early 20th century,Qing Dynasty and the Northern Warlords Government of the Republic of China had passed several laws and regulations on non-governmental associations,which had legally supported,to certain extent,the development of non-governmental associations in China,though there were much room for improvement.After a careful study,the author of this article has found that the legislation on non-governmental associations had experienced different stages: complete prohibition,partially prohibition,partially permission with conditions,totally permission under the state of anarchy,and permission with government's will.


Using data from a Bank of Italy survey, this paper analyzes the Italian taxi market and its recent changes. Local regulations are rather homogeneous, while there is a widespread disproportion, within municipal advisory committees, between the number of representatives of taxi drivers and that of consumers' advocates. Indicators of service adequacy are seldom used. The average service costs are rather homogeneous across Italian provinces, while there is great variance of supply and fare structures. The instruments made available to municipalities by the Bersani Law 2006 have been used mainly in large cities. In many cases, the expansion of service, achieved mainly through additional shifts rather than through the issue of (free) additional licenses, has been the result of a trade-off for fare increases (in part to protect drivers' income). Virtually no use has been made of municipal traffic rules. All in all it is difficult to evaluate the suitability of the decisions of municipalities with respect to market characteristics, given the lack of non-occasional information on market structure.


This research aims to understand the reasons behind Indonesia trade with Argentina in the period 2008-2013. The formulation of the problem in this research is the "Why Indonesia keep doing trade with Argentina in the years 2008 to 2013 but the balance of trade deficit?". Through the frame of economic nationalism, the research found that in line with the value of a strong political history between the two, Indonesia had the interests of market access (trade policy) and strengthening of the domestic industry (industrial policy). Market access in this case related interests of Indonesia who made Argentina as a hub in the region of South America. But in terms of strengthening the domestic industry, not apart from the strengthening of the ranching industry needs through imports of animal feed from Argentina.


Aim: To evaluate the microleakage of self-etch adhesive used with and without pre-etching step, on human dentin contaminated with two different hemostatic agents. Materials and methods Thirty human premolars were collected and class V cavities with standard dimensions were prepared at the cemento-enamel junction on both buccal and lingual surfaces, with the gingival margin is totally placed in dentin. All specimens were randomly assigned into three groups according to the hemostatic agent used (A); A0: No hemostatic agent applied (control group). A1: Hemostop (Dentsply). A2:ViscoStat® (Ultradent). Each group was furtherly subdivided into two subgroups according to the adhesive protocol used (B); B1: Pre-etching was performed. B2: Pre-etching was not performed. The resultant will be six subgroups, each of them was formed of five teeth with 10 cavities (n=10). FiltekTM Z350 XT nano resin was used to restore all cavities according to the manufacturer's instructions. Teeth were exposed to a thermocycling procedure, thereafter, they were stored in artificial saliva for two years. After immersion in 2% methylene blue dye, Microleakage was measured using USB Digital microscope with a built-in camera connected with an IBM compatible personal computer using a fixed magnification of 40X. Results: A two-way unrelated ANOVA showed significant main effects (p=0.0001) for hemostatic agent, with large effect size η2=86.5%, adhesive protocol with medium effect size η2=68.6%, and the interaction between hemostatic agent and adhesive protocol but with small effect size η2=34.2%.The Duncan post-hoc test revealed a significant difference between all groups except between the groups of Viscosat with pre-etching adhesive protocol (0.54 ± 0.03) on one hand and Hemostop with and without pre-etching adhesive protocol (0.53 ± 0.02) and (0.61 ± 0.04), respectively on the other hand (p > 0.05 ). Conclusions: 1. Contamination with hemostatic agents adversely affected the bonding qualities of self etch adhesives applied with and without pre etching step. 2. Dentin etching prior to self etch adhesives minimized the harmful effect of the hemostatic agents. (1562) Hossam Al Mandouh and Inas Alzayat E.D.J. Vol. 64, No. 2


In this paper, we study efficient and authorized rewriting of transactions already written to a blockchain. Mutable transactions will make a fraction of all blockchain transactions, but will be a necessity to meet the needs of privacy regulations, such as the General Data Protection Regulation (GDPR). The state-of-the-art rewriting approaches have several shortcomings, such as being coarse-grained, inability to expunge data, absence of revocation mechanisms, lack of user anonymity, and inefficiency. We present ReTRACe, an efficient framework for transaction-level blockchain rewrites, that is fine-grained and supports revocation. ReTRACe is designed by composing a novel revocable chameleon hash with ephemeral trapdoor scheme, a novel revocable fast attribute based encryption scheme, and a dynamic group signature scheme. We discuss ReTRACe, and its constituent primitives in detail, along with their security analyses, and present experimental results to demonstrate scalability.


Four cases of hyperthyroidism were observed in a series of 135 males with a past history of malignant teratoma of testis. None of the patients had evidence of tumour recurrence at the time of diagnosis of hyperthyroidism. Possible mechanisms for this association are discussed.


A lock-free algorithm for Linux packet buffer recycling on multi-core processor was proposed.Through making a model of Linux network packet forwarding, the principle of Linux packet buffer recycling was analyzed, and the main reason that the mechanism wasn't extensible on multi-core processor was pointed out .It was that mutual exclusion and cache coherence operations consumed too much CPU clock tick.A new buffer recycling algorithm named MSRQ was designed and implemented.With the new algorithm, the parallel operations on the recycling queue were permitted without mutual exclusion on multi-core processor.And the new algorithm had better cache behavior than original recy-cling algorithm.The experiment result shows that the performance of Linux network packet forwarding with the new algorithm can be improved more than 67%.


The goal of this project was to collect suspended particles and microbes for spectral analysis from deep water around hydrothermal vent study sites on the Juan de Fuca Ridge. To accomplish this, the McLane WTS 6-24-47 Sampler (McLane Research Laboratories, Falmouth, MA) was used. The WTS sampler is a programmable unit which is able to collect individual samples across twenty-four 47mm diameter filters at predetermined intervals and duration. Although only one successful deployment was needed, a maximum of three 3 deployments were possible (deployment opportunities were limited by the number of battery packs available). The initial behavior of the WTS and the ship's schedule both indicated that three deployments would be possible. However, it was revealed upon recovery after the first deployment that the WTS failed as it was preparing to collect its first sample.


The paper presents a possibility of monitoring the operating regimes for the different electrical loads by the analysis of the harmonic components extracted from alternating currents and also by establishing the phase shift between the voltage and current waveforms. With this method is determined the electrical load character (inductive, capacitive, resistive, resistive – inductive), and is established the electric pattern of the loads from the electrical network analyzed.


This is the initial establishment data from field trials of tall fescue growing in natural shade conditions. This is a National Turfgrass Evaluation Program (NTEP) ancillary trial, and is being conducted at several research stations in the United States. It contains 132 seeded cultivars, including a number of new experimental cultivars. Iowa State is home to both a traffic tolerance and shade setting of this trial.


Simple Summary Long-term selection should lead to reduction in heritability, due to fixation of positive alleles. Selection on multiple traits should lead to negative genetic correlations because alleles with positive effects on both traits will respond first to selection, leaving alleles with opposing effects. Efficient selection for milk production traits began in Israel in the 1980s, and selection for female fertility in 2000. Introduction of genomic selection increased rates of genetic gain. Many studies have shown the negative relationships between milk production traits and female fertility. Phenotypic and genetic changes for female fertility and production traits in the Israeli dairy cattle population over the last three decades were studied in order to determine if long-term selection has resulted in reduced heritability and increased negative genetic correlations. Heritabilities were 0.4 for protein production and 0.05 for conception status. The genetic correlation between conception status and protein yield was −0.38. Heritabilities decreased with increase in parity for protein but remained the same for conception status. For milk, fat, and protein production and female fertility, heritabilities increased or stayed the same over the entire period of 30 years. There is no indication that a selection plateau is imminent for dairy cattle. Abstract Phenotypic and genetic changes for female fertility and production traits in the Israeli Holstein population over the last three decades were studied in order to determine if long term selection has resulted in reduced heritability and negative genetic correlations. Annual means for conception status, defined as the inverse of the number of inseminations to conception in percent, decreased from 55.6 for cows born in 1983 to 46.5 for cows born in 2018. Mean estimated breeding values increased by 1.8% for cow born in 1981 to cows born in 2018. Phenotypic records from 1988 to 2016 for the nine Israeli breeding index traits were divided into three time periods for multi-trait REML analysis by the individual animal model. For all traits, heritabilities increased or stayed the same for the later time periods. Heritability for conception status was 0.05. The first parity genetic correlation between conception status and protein yield was −0.38. Heritabilities decreased with the increase in parity for protein but remained the same for conception status. Realized genetic trends were greater than expected for cows born from 2008 through 2016 for somatic cell score, conception status and herd-life, and lower than expected for the production traits.


We consider secure communications over MIMO wiretap channels, in the presence of a passive eavesdropper with an unlimited number of antennas. In this scenario, we characterize the performance of the artificial noise scheme proposed by Goel et al., and show that non-zero secrecy capacity is available even when the eavesdropper has more antennas than the transmitter. Our results are derived based on the fraction of the transmission power used for artificial noise and the ratio of the channel noise variances of the eavesdropper and the intended receiver. Finally, we investigate the attack option for the eavesdropper to drive the secrecy rate to zero by increasing the number of antennas.


The past exerts a distinct and powerful influence in most of southern fiction. This is no less true in the works of contemporary women writers who are southern themselves or whose works fall in the realm of southern fiction. In the hands of Lee Smith and Gloria Naylor, the past becomes a multi-dimensional, prismatic entity that shapes familial, community, and cultural history. In Oral History by Lee Smith and in Mama Day by Gloria Naylor, the concern is not so much with preserving the past, but with examining, deconstructing, and ultimately redefining the past. These novels represent two diverse aspects of southern culture and experiences of the past. Oral History focuses on white Appalachian culture, while Mama Day focuses on rural black island culture. Despite the differences of race and culture, these two novels share remarkable similarities in their treatment of the past and in the importance of individual voices in revealing the past. Smith and Naylor use similar narrative techniques to relate familial and cultural histories. Taken together their novels yield a portrait of the past that is prismatic and yet, at the same time, strangely unified. To complicate matters, the worlds and voices that Smith and Naylor each creates in rendering the past stand as metaphors for the Other Indeed, characters from Oral History and Mama Day (as well as the authors themselves) are the gender and racial representations of the non-canonical which stand in opposition to "traditional" white male Western literature. Place also figures significantly into this: Smith's Hoot Owl Holier and Naylor's Willow Springs are isolated communities that serve as the repositories of memories and experiences of the Other. Henry Louis Gates, Jr. states that race (and, by extrapolation, gender) has been "an invisible quantity, a persistent yet implicit presence" in the study of literature (2). In defiance of this, Oral History and Mama Day come together in their presentation of the Other as a vital and explicit element infusing each work. In both novels the Other is manifested in several ways and is central to the mystery at the center of the past. Women's voices and racial and cultural histories inherent in each work constitute the force of the Other. The reliance on orality in conveying the past further enhances the Other's presence. However, this emphasis on orality rather than on the more traditional written word makes the past far more difficult to comprehend. In trying to decipher the past in Smith or Naylor's novel, one is like "the inquiring anthropologist, who must learn the language, listen and report, with all the implicit risks of distortion involved in the child's game of telephone" (Miller 286). In this process of revealing the past through multiple narrators, Smith herself emphasizes that "no matter who's telling the story, it is always the teller's tale, and you never finally know exactly the way it was" (qtd. in Arnold 246). While distortion may be inevitable and the truth about the past never fully known, all of this is part of a complex process that reveals the rich and prismatic quality of the past in both Smith and Naylor's works. In Oral History the past is presented as a family and cultural history which is in sore conflict with the present. Through the narratives of different characters, the rich Appalachian past of the novel is conveyed in the recitation of stories, folklore, and legends as they pertain to Hoot Owl Holler and the Cantrell family. In this process, Smith incorporates the perspectives of such characters as Mrs. Ludie Davenport, Jink Cantrell, Ora Mae, and Little Luther Wade. In all, Smith utilizes nine voices, including what appears to be a community voice, to reveal Hoot Owl Holler's history and the Cantrell family saga. These various narrators share the same community history and participate in the same collective memory. However, each character has a different perspective and experience of these things. …


Let $p<q$ be odd primes, $\rho_1$ and $\rho_2$ be irreducible representations of $\text{SL}(2,\mathbb{Z}_p)$ and $\text{SL}(2,\mathbb{Z}_q)$ of dimensions $\frac{p+1}{2}$ and $\frac{q+1}{2}$, respectively. We show that if $\rho_1\oplus\rho_2$ can be realized as modular representation associated to a modular fusion category $\mathcal{C}$, then $q-p=4$. Moreover, if $\mathcal{C}$ contains a non-trivial \'{e}tale algebra, then $\mathcal{C}\boxtimes\mathcal{C}(\mathbb{Z}_p,\eta)\cong\mathcal{Z}(\mathcal{A})$ as braided fusion category, where $\mathcal{A}$ is a near-group fusion category of type $(\mathbb{Z}_p,p)$. And we show that there exists a non-trivial $\mathbb{Z}_2$-extension of $\mathcal{A}$ that contains simple objects of Frobenius-Perron dimension $\frac{\sqrt{p}+\sqrt{q}}{2}$.

In this paper, the study on applications of radio frequency nano antenna energy conversion and supercapacitors is presented. Radio Frequency (RF) signals are a form of electromagnetic radiation with wavelengths greater than 3 meters. Initially used in wireless communication devices like radios and walkie-talkies, RF signals have found their way into energy conversion and storage applications. When RF signals are received by an antenna with coupled capacitors and a rectifier circuit, they generate a potential difference of a few millivolts. This potential difference can be used as a stable source of energy to power low-voltage applications through ambient RF radiation, and excess energy can be stored in electrochemical storage systems like supercapacitors and lithium-ion batteries. While this technology is currently limited to low-power applications, it has immense potential in various fields such as medicine, automotive industry, military applications, and more. Researchers are currently working to improve the energy density of supercapacitors by modifying their electrode materials using nanotechnology. One promising material is lignin, derived from wood fibers, which has shown great performance in tests and is expected to be a low-cost solution for high-performance batteries and supercapacitors. As the renewable energy sector continues to advance, we can expect to see more useful applications based on RF nano antennas and micro/nano-sized supercapacitors.

157 Abstract— Space vector pulse width modulation (SVPWM) is an optimum pulse width modulation technique for an inverter used in a variable frequency drive applications. It is computationally rigorous and hence limits the inverter switching frequency. A neural network has the advantage of very fast implementation of an SVPWM algorithm that can increase the inverter switching frequency. This paper proposes a neural Network based SVPWM technique for a three-phase voltage source inverter in under modulation region. The scheme has been simulated and implemented on a V/Hz controlled 5-hp, 50-Hz, and 230V induction motor drive. The simulation results are given to validate the performances of the drive with artificial neural network based SVPWM.


My thesis will begin to examine alcoholism and recovery through the lens of moral injury, especially in relationship to the use of spirituality language and the often-invoked correlation between spirituality and sobriety. Through a literature review and interviews with abstaining alcoholics, I will unpack some of the implications of considering alcoholism through the lens of moral injury and begin to frame and examine some of the questions inherent in that consideration. By so doing, I hope to offer a fresh look into those aspects of recovery that fall within the Religious Studies purview. INDEX WORDS: Moral Injury, Alcoholism, Veterans, Alcoholics Anonymous, Celebrate


Aim

The geographic distributions of different forest types are expected to shift in the future under altered climatic conditions. At present, the nature, magnitude and timing of these shifts are uncertain because we lack a quantitative understanding of how forest distributions emerge from climate- and competition-related variation in underlying demographic processes. Forest dynamics result primarily from the manner in which the physical environment and competition for limiting resources affect tree growth, mortality and recruitment. We sought to uncover the relative importance of these processes in controlling the geographic limits of different forest types.

Location

Eastern USA.

Methods

We parameterized a climate-dependent forest dynamics model with extensive observations of tree growth, mortality and recruitment from forest inventory data. We then implemented the resulting demographic models in simulations of joint population dynamics for seven plant functional types (PFTs) across the region. By removing various climate effects in a series of simulation experiments, we assessed the importance of climate-dependent demography and competition in limiting forest distributions.

Results

Distributions that emerged from simulated population dynamics approximated the current distributions for all seven PFTs well and captured several known patterns of succession. Temperature-related increases in mortality determined the southern boundaries of three out of four boreal and northern temperate PFTs, whereas temperature-related decreases in recruitment controlled the northern limit of all three southern temperate PFTs. Changes in growth rates and competitor performance had only minor effects on the distribution limits of most PFTs.

Main conclusions

Our results imply that dynamic global vegetation models, which are widely used to predict future vegetation distributions under climate change, should seek to more appropriately capture the observed climate sensitivity of mortality and recruitment. Understanding the mechanisms controlling forest distributions will enable better predictions of their future responses to climate change.


This paper introduces a notion of decomposition and completion of sum-of-squares (SOS) matrices. We show that a subset of sparse SOS matrices with chordal sparsity patterns can be equivalently decomposed into a sum of multiple SOS matrices that are nonzero only on a principal submatrix. Also, the completion of an SOS matrix is equivalent to a set of SOS conditions on its principal submatrices and a consistency condition on the Gram representation of the principal submatrices. These results are partial extensions of chordal decomposition and completion of scalar matrices to matrices with polynomial entries. We apply the SOS decomposition result to exploit sparsity in matrix-valued SOS programs. Numerical results demonstrate the high potential of this approach for solving large-scale sparse matrix-valued SOS programs.


The organization of genomic DNA with histones and other proteins ensures the proper storage, utilization and segregation of DNA's encoded information in a healthy eukaryotic cell. These components comprise chromatin, and knowledge of its structure, mechanisms of its formation, and the dynamic changes it undergoes is essential to gain insights into chromatin's role in controlling gene regulation and the defects associated with misregulation. Here we describe our efforts to understand the different aspects of chromatin by using existing and modified in vitro chromatin model systems. To better understand histone-histone interactions involved in the formation of higher-order chromatin structure, we employed a disulfide crosslinking strategy previously used to study short-range nucleosomal interactions. Using in vitro assembled nucleosomal arrays, we show that histones H4 and H2A, belonging to nucleosomes on different arrays, directly interact with each other under conditions that promote array-array associations. Additionally, prior intra-array cross-linking of nucleosomal arrays has an antagonistic effect on inter-array self-association. Together, our data show the role of H4-H2A contacts in the interplay between short-range nucleosomal compaction and higher-order chromatin structure. Nucleosomal arrays used above, generated by assembling histone octamers on DNA templates, provide an excellent model system due to their


Image stitching describes the process of reconstruction of a high-resolution image by combining multiple images. Using a scanning electron microscope as the image source, individual images will show patterns in a nm dimension, whereas the combined image may cover an area of several mm2. The recovery of the physical layout of modern semiconductor products manufactured in advanced technologies nodes down to 22 nm requires a perfect stitching process with no deviation with respect to the original design data, as any stitching error will result in failures during the reconstruction of the electrical design. In addition, the recovery of the complete design requires the acquisition of all individually layers of a semiconductor device. The layers represent a 3D structure with interconnections defining error limits on the stitching error for each individual scanned image mosaic. An advanced stitching and alignment process is presented, enabling a true geometrical layout recovery in nanoscale dimensions, which is also applied to and evaluated for other use cases from biological applications.


Freshwater is undeniably an essential life-sustaining element. It is a key ingredient in the health and well-being of humans and ecosystems, and for socio-economic development. Therefore, it becomes essential to manage, in a balanced way, this natural resource. Most problems related to water quality are caused by intensive agriculture, industrial production, mining, untreated urban runoff and wastewater. The Sousa River belongs to the hydrographic basin of the Douro River, located in the north of Portugal, extending for approximately 95 km, and its spring is in Felgueiras. It crosses Felgueiras, Lousada, Penafiel, Paredes and flows into the Douro River in Gondomar. Thus, the study's main goals were to evaluate the ecological status and quality of the Sousa River through the analysis of biological components (benthic diatoms and macroinvertebrates), as well as physicochemical and hydromorphological parameters. Research was performed during 9 months (November 2016 to July 2017), in four distinct sampling stations. The sampling included physicochemical and hydromorphological parameters as well as biological parameters. Samples were collected every three months, except in winter. Hence, through the assessment of the physicochemical water quality, it was recognised that high levels of organic pollution existed, especially during spring and summer. The evaluation of the physical habitat revealed slight transformations in the channel of the river and the poor ability for the riparian zone to function as a barrier to the anthropogenic impacts. Moreover, the study of the benthic macroinvertebrate community indicated that the river is somewhere between slightly contaminated to moderately contaminated presenting, in some sampling sites, "Good" to "Poor" Quality. The benthic macroinvertebrate diversity was high with populations dominated mostly by tolerant taxa to organic pollution. Regarding, the diatom community, these indicated that the Sousa River presented a "Reasonable" quality throughout the seasons and sampling sites, with populations dominated mainly by tolerant and ubiquitous taxa. The results obtained were important since they may serve as an incentive to the elaboration of future research works that can provide integrated management solutions of the natural resources.


The citizenship of a country brings many benefits to inhabitants, but above all to those who are immigrants. The objective of this article is to reflect on Argentine citizens with dual nationality, who due to the economic or political situation decided to emigrate from the province of Misiones to Switzerland or Germany. The concept of citizenship is often thought of as something simple, but when describing the plot of elements interrelate individual instance with the political system, the concept becomes more complex. In the right to Argentine citizenship, the ius solis prevails: being born on this land grants an inalienable nationality. These rights intrinsic to the ius solis or the "nationalization" of foreigners, are contrasted with countries granting citizenship by the ius sanguinis. The tension generated in the descendants of immigrants between the ius sanguinis of the nation of origin and the ius solis of Argentina is reflected in this article in four sections: the first is a brief contextualization of the German-Brazilian, German and Swiss migration to Misiones, in the second is exposed the difference between these nationalities-citizenships; to continue with some cases that have been traced along different investigations about Argentines who emigrated to Switzerland or Germany. Finally, we come to some reflections on transnational citizenship in relation to dual citizenship.

I1a 1972 the Board of Directors of the National Society for the Study of Education sought the advice of several educators with respect to the nature of a possible yearbook on secondary education in the United States. A large majority of the respondents urged that such a yearbook should focus oll central issues. An advisory group, consisting of Arno A. Bellack, Louise M. Berman, Catherine McKenzie, Harold G. Shane, J. Lloyd Trump, William Van Til, and Gordon 17. Vats, was then convened to give further consideration to the nature of an issue-oriented yearbook. At its meeting in September of 1973 the Board acted favorably on a proposal for the yearbook and appointed a yearbook committee consisting of the following persons: Arno A. Bellack, Virgil A. Clift, Harold G. Shane, J. Lloyd Trump, YVilliam Van Til (chairman), and Gordon F. Vars. The committee met with Robert J. Havighurst and Kenneth J. Rehage and agreed upon the central issues to be treated in the volume, the related issues and topics to be considered, the immediate cutting points and concerns, the basic structure of the yearbook, and the names of individuals to be invited to write on selected issues. Because of other commitments, Professor Bellack withdrew from the committee ira 1974. Following an introductory chapter by William Van Til, the yearbook turns to a history of issues ira secondary education in a chapter prepared by Robert H. Beck. Chapters devoted to each of nine central issues follow. :Fhe authors of these chapters are Arthur \V. Combs, Lawrence E. Metcalf, \,Villis YV. Harman, Arthur \V. F'oshay, Vernon H. Smith and Robert D. Barr, YVilliam Van Til, J. Lloyd Trump and Gordon F. Vars, Ronald T. Hyman, and Ronald C. Doll. The yearbook concludes with speculation on the future of secondary education in a chapter by Virgil A. Clift and Harold G. Shane. The Committee is especially grateful to Herman G. Richey, formerh, Secretary-Treasurer and Editor for the Society, who prepared the index for the volume.


ABSTRACr.-I determined the fatty acid composition of subcutaneous, abdominal, visceral, and leg saddle depots in adult female Canada Geese (Branta canadensis) wintering in north-central Missouri during October 1984-March 1985. Mean levels of C14:0, C16:0, C16:1, C18:0, C18:1, C18:2, and C18:3 generally were highest in the subcutaneous and abdominal depots. The ratio of saturated to unsaturated fats was highest in the leg saddle depot and lowest in the abdominal depot. I also assessed the differences among sexes, seasons, and years in fatty acid composition of abdominal fat depots in adult geese collected during October-March, 1985-1987. Adult females had consistently higher levels of C14:0 in abdominal depots than males. Fatty acid composition of the abdominal depot differed among years but not by season. In the abdominal depot, C14:0, C16:0, C16:1, and C18:1 were higher in 1986-1987 compared with the previous two years, whereas C18:3 was highest in 1984-1985. Differences among years reflected changes in winter diet. Fatty acids of wintering geese were similar to those previously found in breeding Canada Geese.
