The objective of this work was to promote the autolysis and the fractionation of the yeast (Saccharomyces sp.) for the production of autolysate and extract, as well as phosphorylated protein concentrate, from ethanol distillery yeast. Comparative studies of centesimal composition, essential amino acid profiles and protein nutritive value were performed for the unprocessed integral cells, and for autolysate, extract and phosphorylated protein concentrate. Protein and carbohydrate (dietary fiber) were the main components for the integral cells and autolysate. For the extract and the protein concentrate the main components were protein and minerals (ashes). The autolysate and the integral cells presented the highest essential amino acid indexes, followed by the protein concentrate and the extract. Protein digestibility ranged from 68% (integral cells) to 91% (extract). Net protein ratio ranged from 2.1 (integral cells) to 4.3 (casein-reference). There was no statistical difference in Net protein ratio among autolysate, extract and protein concentrate (3.9 to 4.2). The protein concentrate promoted the highest growth in the period (21 days), followed by the extract and the autolysate. The integral cells showed the lowest capacity to promote rat growth.


Building upon the suggestions of Arvey and Campion (1982) and Zedeck, Tziner, and Middlestadt (1983), this paper calls into question the traditional approach to validating the employment interview. A general review of the literature reveals that individuals are likely to differ in their ability to provide accurate predictions of employee behavior and that interviewers often differ in their constant tendency to make favorable or unfavorable ratings. A review of published validation studies shows that most researchers fail to consider these tendencies and, therefore, may be inappropriately collapsing data across multiple interviewers. Through analytic argument we conclude that reviews of the existing literature will likely underestimate the usefulness of this widely used technique.


Structural analysis and new geochronologic data indicate a nearly orthogonal, Oligocene flow pattern in migmatitic infrastructure immediately beneath the kilometer-scale mylonitic shear zone of the Ruby Mountains metamorphic core complex, Nevada. Three zircon fractions from a biotite monzogranitic orthogneiss yielded a crystallization age of 30 [+-] 1 Ma. Single monazite fractions from two leucocratic granitic orthogneisses indicated a preliminary crystallization age of 37 Ma. These three samples all exhibit a penetrative, approximately north-south-trending elongation lineation. The elongation lineation is interpreted as the slip line in the flow plane of the migmatitic, nonmylonitic infrastructural core of the northern Ruby Mountains. This flow pattern is coeval with the well-documented, west-northwest sense-of-slip in the structurally overlying kilometer-scale mylonitic shear zone suggesting fundamental plastic decoupling between structural levels in this core complex. Furthermore, the study area is characterized by overlapping, oppositely verging fold-nappes which are rooted to the east and west. The penetrative, elongation lineation is subparallel to parasitic folds developed synchronous with the fold-nappes suggesting a kinematically related evolution. One possible model is that late Eocene-early Oligocene granitic magmas invaded a migmatitic core zone undergoing a complex flow pattern related to large-scale crustal extension. The local flow pattern in the migmatitic infrastructure maymore » be a manifestation of mid-crustal migration of low viscosity crustal material into an area beneath a domain of highly extended upper crustal rocks.« less


Abstract We construct a new 20-dimensional family of projective hyper-Kähler fourfolds and prove that they are deformation-equivalent to the second punctual Hilbert scheme of a K3 surface of genus 12.


Dialogue with Canadian family practice faculty and teachers indicates that the mentorship experience is one that cannot be assigned to a learner. The mentorship experience is one that develops out of a fortuitous relationship that helps the learners, both student and mentor, define support and attain their professional aspiration. It is clear that mentors cannot be assigned, but that mentorship relationships grow. There are however aspects of a mentorship that you can ascribe and explore in a family practice residency training program.


The utility model discloses an armrest-insertable sofa which comprises a backrest, a base and armrests, wherein the armrests are arranged on both sides of the sofa, the armrests are arranged on the base, the bottom of each armrest is provided with at least two inserted links, and the surfaces of the left and right ends of the base have at least two inserting holes matched with the inserted links at the bottoms of the armrests; and the backrest is arranged at the rear end of the base, the width of the backrest is less than the width of the base, and the backrest is clamped between the two armrests. The inserted links at the bottoms of the armrests are inserted pin screws, and the inserting holes in the surface of the base are inserted pin holes. According to the utility model, the armrests on the two sides of the sofa can be conveniently separated from the base, so that when the sofa is folded, the space is saved; and meanwhile, a user purchases a sofa equipped with multiple pairs of armrests, so that an effect of various transformation can be achieved.

How to improve employees' work engagement currently represents one of the most important areas of concern for organizations. Within the broader research fi eld on work engagement and its antecedents, this study analyzes one specifi c aspect: the role of job resources in determining employees' engagement at work. A hierarchical multiple regression analysis was performed, along with a basic descriptive analysis, to examine a sample of 167 caregivers (registered nurses, nurse managers, home helpers, nurse's aides, and certifi ed nursing assistants) in nine long-term care (LTC) facilities in Italy. The results suggest that work engagement among caregivers in the LTC sector is signifi cantly infl uenced by job resources. In particular, greater learning opportunities have direct effects on increasing work engagement among health-care service employees. Furthermore, coworker support and supervisor support also play a statistically signifi cant positive role in stimulating work engagement.


Occasionally in recent decades, relations between the Canadian state and particular Native communities have spiralled into open confrontation and violence. While such instances reflect the failure of conciliatory or decolonizing politics within a liberal–democratic milieu, scholarship has barely begun to analyze these events in a systematic fashion. This article applies to long-standing questions about political behaviour to the study of Native-state relations in Canada. By this, the authors particularly mean the dynamics of Native peoples' mobilization and institutional engagement. Examining several recent cases of open confrontation, this article looks for the basic circumstances in which violence arises, and how confrontation alters internal political dynamics in Native communities.


Following a recent theory of diffusion in a lattice gas, we present a generalization of the local mean-field approach to study diffusion in a dense system in which particles are mobile. Our model reduces in well-defined limits to the lattice gas and fluid models which we have proposed recently for an adsorbate diffusion on the surface of a metal.


Speech quality is often measured via subjective testing, or with objective estimators of mean opinion score (MOS) such as ViSQOL or POLQA. Typical MOS-estimation frameworks use signal level features but do not use language features that have been shown to have an effect on opinion scores. If there is a conditional dependence between score and language given these signal features, introducing language and rater predictors should provide a marginal improvement in predictions. The proposed method uses Bayesian models that predict the individual opinion score instead of MOS. Several models that test various combinations of predictors were used, including predictors that capture signal features, such as frequency band similarity, as well as features that are related to the listener, such as a language and rater index. The models are fit to the ITU-T P. Supplement 23 dataset, and posterior samples are drawn from distributions of both the model parameters and the resulting opinion score outcomes. These models are compared to MOS models by integrating over posterior samples per utterance. An experiment was conducted by ablating different predictors for several types of Bayesian hierarchical models (including ordered logistic and truncated normal individual score distributions, as well as MOS distributions) to find the marginal improvement of language and rater. The models that included language and/or rater obtained significantly lower errors (0.601 versus 0.684 root-mean-square error (RMSE)) and higher correlation. Additionally, individual rater models matched or exceeded the performance of MOS models.


ABSTRACT Steric/hyperlayer flow field-flow fractionation (St/Hyp/FlFFF) is suitable for the separation and characterization of micrometer-sized particles. In this technique, an ultrafiltration membrane is commonly used as the surface of the accumulation wall. St/ Hyp/FlFFF has been recently tested in membraneless mode and an improvement in performance was found. Recovery was also improved and second-order effects were reduced. In the framework of St/Hyp/FlFFF optimization, the effect of sample loading is a problem of a certain importance. For quantitative purposes, the conversion of peaks into mass particle size distributions is of prime importance and, therefore, the conditions in which there is no effect of sample loading on recovery should be investigated. In this paper, systematic work was performed in order to study the effect of sample loading on recovery. We have found the conditions in which recovery is independent of sample loading. For these conditions, the limit of detection for various micrometer-size standard polystyrene particles was calculated. The absolute sample recovery was calculated by applying a quantitative method for single-run analysis in FFF with UV/Vis detectors.

Zhu, S. sinica var. dentata (K. S. Hao ex C. F. Fang & Skvortsov) G. Zhu, and S. sinica var. subsessilis (K. S. Hao ex C. F. Fang & Skvortsov) G. Zhu are proposed. Salix hylonoma C. K. Schneider var. liocarpa (Girz) G. Zhu and S. spodiophylla Handel-Mazzetti var. liocarpa (K. S. Hao ex C. F. Fang & Skvortsov) G. Zhu are new statuses and combinations. For the treatment of the Salicaceae in the Flora of China, valid publication of two species is needed; nine new combinations are also required; and two forms need to be raised to varietal rank. All are accomplished here. Populus wenxianica Z. C. Feng & J. L. Guo ex G. Zhu, sp. nov. TYPE: China. Gansu: Wenxian, Zhongzhai, J. F Liu 88001 (holotype, GAUF). This species is based on Populus wenxianica Z. C. Feng & J. L. Guo, which was incompletely described in Acta Botanica Boreali-Occidentalia Sinica (Feng & Guo, 1990: 132). These authors neglected to select an item among the four cited specimens to typify this name. According to the International Code of Botanical Nomenclature (Greuter et al., 1994, Articles 8.1 and 37.1), a name of a taxon published after 1958 must have a single-element type cited in order to be valid. Therefore, by the designation of a holotype, the valid publication of the name is achieved here. The four specimens cited by Feng and Guo are from the same locality of Zhongzhai in Wenxian, Gansu, China: J. L. Guo 88008 (9 inflorescence), J. E Liu 88001 ( inflorescence), J. L. Guo 89003 (infructescence), and J. L. Guo 88012 (infructescence). One of the key characters differentiating this species from its close relative, P gansuensis C. Wang & H. L. Yang, is its many stamens, which are present on the specimen J. E Liu 88001. Therefore, J. F Liu 88001 is designated here as the holotype of P wenxianica.

This variety differs from Salix eriostachya var. eriostachya only in having a smaller bract, shorter peduncle, and a more or less stipitate ovary, but it is distinguished sharply from S. dolia C. K. Schneider by having a deeply bilobed style and stigmas. Salix fargesii Burkill var. kansuensis (K. S. Hao ex C. F. Fang & Skvortsov) G. Zhu, comb. nov. Basionym: Salix kansuensis K. S. Hao ex C. F.

This variety differs from varietyfargesii in having glabrous ovaries and capsules. However, specimens of variety fargesii sometimes also have pilose ovaries. The variety kansuensis may be just a synonym of variety fargesii. NOVON 8: 464-466. 1998.

The European species Salix triandra is currently accepted as not occurring in China (C. F. Fang & A. Skvortsov, pers. comm.). Its inclusion in the Flora Reipublicae Popularis Sinicae (Wang & Fang, 1984) was due to the misidentification of some specimens of S. nipponica, which differs from S. triandra in having whitish powder on the secondyear branches. Based on its description (Liang, 1988), this variety is more properly placed under S. nipponica and differs from variety nipponica in having long whitish hairs on buds and new branches and female flowers without a dorsal gland. Salix opsimantha C. K. Schneider var. wawashanica (Mao & P. X. He) G. Zhu, comb. nov. Basionym: Salix oreinoma Schneider var. wawashanica Mao & P. X. He, Acta Bot. Yunnan. 9(1): 47. 1987. TYPE: China. Yunnan: Jingdong County, North Wawashan, 2300 m, Anquan Wu 9345 (holotype, KUN). In the Flora Reipublicae Popularis Sinicae (Wang & Fang, 1984), the species described under Salix oreinoma C. K. Schneider is, in fact, S. opsimantha C. K. Schneider, and vice versa (C. F. Fang & A. Skvortsov, pers. comm.). The illustration captioned S. oreinoma on plate 54 of the Flora depicts S. opsimantha. Salix oreinoma C. K. Schneider var. wawashanica Mao & P. X. He was described under the wrong species because of the error in the Flora (Mao & Li, 1987) and should therefore be a variety of S. opsimantha. Salix oritrepha C. K. Schneider var. amnematchinensis (K. S. Hao ex C. F. Fang & Skvortsov) G. Zhu, comb. nov. Basionym: Salix amnematchinensis K. S. Hao ex C. F. Fang & Skvortsov, Novon 8: 467. 1998. TYPE: China. Qinghai: Gan Ba, 4500 m, K. S. Hao 1039 (holotype, PE). This variety differs from variety oritrepha only in having elliptic-ovate or elliptic-lanceolate leaves. Leaves of variety oritrepha are often elliptic or ovate. Salix sinica (K. S. Hao ex C. F. Fang & Skvortsov) G. Zhu, comb. nov. Basionym: Salix caprea L. var. sinica K. S. Hao ex C. F. Fang & Skvortsov, Novon 8: 467. 1998. TYPE: China. Hebei: Wuliang Shan, 1270 m, K. M. Liu 49 (holotype, PE). This variety is based on Salix caprea L. var. sinica K. S. Hao, described among many other taxa without Latin diagnoses in the well-known "Synopsis of Chinese Salix" (Hao, 1936), and validated in this issue of Novon by C. F. Fang and A. K. Skvortsov. Specimens of Salix sinica from northern and northeastern China have often been misidentified as S. caprea. However, the former species can be distinguished by its having filaments six to seven times longer than the bracts, ovaries longer than the pedicels, and often thick, pubescent leaves. Salix sinica was invalidly proposed in the Flora Reipublicae Popularis Sinicae (Wang & Fang, 1984: 304) based on the then invalid S. caprea L. var. sinica K. S. Hao. Therefore, the valid publication of the combination is achieved only here. The species is currently recognized as having three varieties: var. sinica, var. dentata, and var. subsessilia. KEY TO VARIETIES OF SALIX SINICA la. Ovary distinctly stipitate. 2a. Leaf margins often entire or irregularly toothed; leaves cuneate at base and acuteacuminate at apex var. sinica 2b.

The utility model discloses a post operating circuit protective device of a two-path power supply system, comprising an on-off control circuit and a testing circuit, wherein the on-off control circuit is arranged between a power supply source and a power switching circuit; the testing circuit is connected to the output end of the power switching circuit to respectively test the working state of two-path power supply and output a state control signal after comparing with a test result; the output end of the testing circuit is connected with the on-off control circuit and the testing circuit; and when any path of the two-path power switching circuit has fault, the state control signal sent from the output end of the testing circuit controls the on-off control circuit to shut off a working power supply, thereby a post operating circuit is protected. The post operating circuit protective device can test whether two-path output voltage exists and test the great reduction of the voltage, and has a simple and reliable circuit.


Studied the phylogenetic relationships of the genus Acomys (represented by A. minous) to other rodent genera of the famiIies Muridae and Arvicolidae (represented by Mus domesticus, Rattus norvegicus, Apodemus flavicollis, and Microtus (Terricola) thomasi, respectively). A total of 51 adult individuals of both sexes were used to determine the albumin differentiation by means of the microcomplement fixation test (MC'F). The immunological distances of Acomys from the murid taxa were found to be greater than that of the Microtus (T.) thomasi to the murid species tested. This means that the Acomys evolutionary lineage splitted off earlier than the appearence of the common ancestor of murids and arvicolids, at a time of 22-27 million ears before present


The results of using the developed methodology for predicting the distribution coefficients of the charge elements between the products of blast-furnace smelting based on the calculation of the integral parameters of the charge and the temperature-blowing regime for modern operating conditions of one of the blast furnaces in Ukraine are presented. The proposed approach differs from traditional methods of considering the distribution coefficients of charge elements as constant values and provides a predictive calculation of the chemical composition of cast iron and slag depending on specific charge and technological conditions when solving the problem of a reasonable choice of the composition of the blast furnace charge.


The current study investigated four possible causal mechanisms underlying the false consensus effect in the context of cigarette smoking. Little support was found for attributional or conformity-based mechanisms. However, support for both a selective exposure and a motivational explanation was found.

It may seem that all the world and his dog has been swept up in the media storm over the clinical grading review.


Wheeled robots enjoy popularity in extensive areas such as food delivery and room disinfection. They can lower labor costs, protect human health from infection, and so on. Given the need to avoid obstacles, the path planning of robots is an elementary module. The A* algorithm has been widely used thus far, but it suffers much memory overhead and provides a suboptimal path. Therefore, we propose an improved A* algorithm with the jump point search method and pruning idea. Specifically, the jump point search method reduces the occupancy rate of the open list. The shorter length of the path can be achieved by pruning. Simulation experiments proved that the improvement was effective and practical.


In today's world, professional athletics increasingly involves long hours of training with repetitive stressful movements of the musculoskeletal system, putting increasing levels of strain on the bones and their support apparatus and resulting in sports specific stress injuries. The prognosis of these injuries relies significantly on early recognition and appropriate management of athletes. The aim of this article is to familiarise radiologists and clinicians with the types of stress injuries and common site-specific radiological presentation of these injuries along with comparison of imaging modalities.

A vast amount of literature has dealt with the role of finite verb placement and its acquisition path in German, both in monolingual German-speaking children (e.g., Clahsen 1982, Clahsen & Smolka 1985, Weissenborn 1990, Tracy 1991, Clahsen, Penke & Parodi 1992, Rothweiler 1993) and in L2-learners (Hamann 2000, Prévost 2003, Rothweiler 2006, Tracy & Thoma 2009, Meisel 2009, among others). Much attention has been paid to detecting when and how children acquire the verb placement parameter and the ability to correctly fill the verb position, namely V2 in finite main clauses and verb-final in subordinate clauses. The data show that German children acquire the verb placement parameter very early and place the verb correctly in both matrix and embedded contexts around age 3 (see Clahsen & Smolka 1985, Wexler 1998). This conclusion is generally shared in the German acquisition literature and has been corroborated by many


Abstract In this paper we study actions of locally compact quantum groups on von Neumann algebras and prove that every action has a canonical unitary implementation, paralleling Haagerup's classical result on the unitary implementation of a locally compact group action. This result is an important tool in the study of quantum groups in action. We will use it in this paper to study subfactors and inclusions of von Neumann algebras. When α is an action of the locally compact quantum group ( M ,  Δ ) on the von Neumann algebra N we can give necessary and sufficient conditions under which the inclusion N α ⊂ N ↪ M α ⋉ N is a basic construction. Here N α denotes the fixed point algebra and M α ⋉ N is the crossed product. When α is an outer and integrable action on a factor N we prove that the inclusion N α ⊂ N is irreducible, of depth 2 and regular, giving a converse to the results of M. Enock and R. Nest (1996, J. Funct. Anal. 137 , 466–543; 1998, J. Funct. Anal. 154 , 67–109). Finally we prove the equivalence of minimal and outer actions and we generalize the main theorem of Yamanouchi (1999, Math. Scand. 84 , 297–319): every integrable outer action with infinite fixed point algebra is a dual action.


It is widely suspected the bulk of star formation precedes the top AGN phase. However, it has also been found evidence of star formation triggered by AGN feedback. Host properties and environmental conditions might then lead us to understand a connection between both phenomena. We then study environmentally-induced galaxies using CALIFA data. We start by determining their nuclear activity and current SFR to compare both with those of non-interacting, star-forming galaxies. We firstly want to corroborate that it is really the intensity of the star-forming bursts what produces the chemical differences of galaxies. Then it follows to estimate the intensity of the central and/or circumnuclear bursts and to determine whether or not it is affected by disturbers.


ABSTRACT In spite of years of sociolinguistic research establishing that all language varieties are valid and equal, there is a disconnect between this knowledge and pedagogical practices at the college level. Certain Englishes, particularly those of minoritized speakers, are stigmatized, and "standard" English is upheld as the goal of writing and literacy instruction. To better understand this disconnect, we conducted a study to examine writing and literacy instructors' attitudes toward "standard" and "nonstandard" Englishes in the community college setting. Employing a critical discursive approach to analyze language ideologies, we discovered that instructors held beliefs that were deeply rooted in standard language ideology, including attitudes toward nonstandard Englishes that superficially expressed tolerance but which underlyingly revealed rejection through lack of appreciation and validation. We argue that professional development that focuses on developing critical language awareness is needed for instructors, which—crucially—must begin with increasing awareness of the language ideologies that govern our beliefs, as these ideologies ultimately discriminate against speakers of stigmatized languages.


Gravity-flow compound ecological filter bed was a kind of environmental bioremediation technology, which based on constructed wetlands and was characterized by high hydraulic loading, more effective treatment, lower energy consumption and more economical. For those advantages, gravity-flow compound ecological filter bed technology was applicable to treat polluted urban river in china. In the treatment project of Dasha river in Shenzhen China, gravity-flow compound ecological filter bed technology was adopted, combined with photocatalytic technology and ecological river bank technology. The application results showed that all kinds of pollutants in upstream river water were removed in various degrees by the treatment of gravity-flow compound ecological filter bed system. Under the hydraulic loading of 1.5m⋅d –1 , the removal rate of NH 3 -N, TP and CODcr pollutants were above 60%, 55% and 50%, respectively, and river water quality was improved significantly.


The principal purpose of this study is to determine from geological and biological evidence how a concentration of fossil bones originated. The Verdigre quarry of earliest Pli— ocene age in the Valentine Formation, northeastern Nebraska forms the basis for the investi— gation. Some 40 genera of mammals, 7 of reptiles, 2 of amphibians, and 6 of fishes are rep— resented in a collection of over 20,000 identifiable specimens recovered from a small exca— vation in a 4-5 foot-thick lens of extremely poorly sorted, gravelly, silty, clayey sand.

The open framework and textural inversion of the fossiliferous stratum indicate very rapid deposition, probably in a single flood. Preferred orientation of long bones shows that the depositional current flowed from the NNW. The site of deposition was an off-channel de— pression on a broad floodplain which was subaerially exposed (mudcracked)prior to the flood.

The great majority of the fossil remains do not represent animals killed by the flood as they are completely disarticulated and often somewhat abraded, except for 7 articulated skele— tons. Stream table experiments suggest that current sorting is probably responsible for the scarcity of elements such as ribs, vertebrae, sacra, and phalanges compared with rami, meta— podia, tibiae, etc.

Discrete age groups, distinguished on the basis of tooth eruption and wear.(Kurten, 1953), are present in Verdigre mammals represented by large samples. Four hundred seventy-five Mery— aodus (antilocaprid)individuals fall into 7 year-classes: one juvenile (.8 year)and 6 adult (1.8- 6.8 years). Burrs on the horns of Meryaodus males are annual but cannot be used in population dynamics studies of collections of transported remains because they are easily re— moved by abrasion. Fifty-seven Protohippus (3-toed horse)individuals fall into 3 juvenile (-.2, .8, and 1.8 years)and at least 7 adult age classes.The lack of individuals of inter— mediate ages and the large proportion of animals of reproductive age in the samples indicate that non-selective catastrophic death accounts for most, and possibly nearly all, of the dis— articulated mammal remains in the quarry. Merycodus and Protohippus at least, died in the winter –– about 2-3 months before the season of giving birth. Growth ring study of catfish vertebrae and gar scales indicates that these aquatic forms were also winterkilled.

Shotwell's (1955)method of determining the proximity of various habitats to vertebrate quarry sites is not applicable to the Verdigre assemblage, and probably not to other collections, because it fails to consider e.g.:

1. sedimentary evidence, such as indications of size-sorting

2. the possibility different effects of catastrophic and attritional mortality on the composition of quarry faunas

3. the great mobility of grazing mammals.

There is evidence that size sorting is responsible for differences in 'completeness' of various mammals in Shotwell's published samples as well as in the Verdigre quarry. Sites of deposition of late Tertiary quarry faunas were in stream valleys; the interstream grassland habitat was probably rarely if ever directly sampled by depositional processes. Mass occurrences of grazing animals such as in the Verdigre bonebed are interpreted as resulting from mortalities which occurred down on floodplains at times of environmental stress.

Early Pliocene vegetation in the Verdigre area resembled that of parts of the Gulf Coast of southern Texas and northern Mexico; forests occupied the broad floodplains and savannas the interfluves (MacGinitie, 1962). Crocodiles and giant land tortoises in the fauna indicate a normally frost-free climate. The presence of sharks and batoids suggests marine influence; stream gradients may have been significantly lower and the shoreline of the Gulf may have been closer to Nebraska in the early Pliocene than at present.


Abstract In this paper, we propose a method of image conversion that changes unglossy images into glossy ones using deep photo style transfer. This style of transfer is expected to reproduce the desired image with a metallic appearance based on the technique used for texture
 transfer. A practical challenge was undertaken to create a gold, metallic image by transferring the style images of a gold ingot. To avoid excessive loss of color balance, we applied the YCrCb separation technique and used only the Y component to reproduce
 a glossy appearance. The luminance and saturation of the style image were altered to investigate the influence on the convergence of appearance because the converted images should be dependent on the contents of the images. The results of transfer were assessed by subjective evaluation using
 the semantic differential method. A style image with an appropriate amount of change in contrast was found suitable for an appropriate glossy appearance. Moreover, contrast in the style image can be appropriately chosen depending on the contents of the original images.


Objective
To investigate the value of hepatocyte growth factor (HGF) and transforming growth factor-β1 (TGF-β1) in the diagnosis of early stage non-small cell lung cancer (ES-NSCLC) through detection of their levels in serum and bronchoalveolar lavage fluid (BALF).

Methods
Serum and BALF samples were collected from 48 cases of ES-NSCLC (at stage 1 and 2), 45 cases of medium and advanced NSCLC (at stage 3 and 4), 42 cases of benign pulmonary nodule and 30 controls for the study. The levels of HGF and TGF-β1 were respectively detected by ELISA, and their differences were analyzed between the 4 groups. The relationship between HGF and TGF-β1 levels and tumor size, differentiation and pathological type was further analyzed, and sensitivity and specificity in the diagnosis of ES-NSCLC was evaluated in the study.

Results
The levels of HGF and TGF-β1 in BALF of the ES-NSCLC group were significantly higher than those in the benign pulmonary nodule group and the normal control group (P 0.05). Serum HGF and TGF-β1 levels in the BALF of the medium and advanced NSCLC group were significantly higher than those in the ES-NSCLC group (P<0.05). The areas under the curve (AUC) in the BALF of HGF and TGF-1 were respectively 0.754 and 0.839. When the levels of 59.32pg/ml and 98.52pg/ml were selected as the optimal cutoff values according to the Jordan index maximum method, the sensitivity of HGF and TGF-β1 in the diagnosis of ES-NSCLC were respectively 41.7% and 81.3%, and specificity were respectively 96.3% and 77.8%. Furthermore, in the patients with adenocarcinoma or tumor size larger than 3cm in diameter, higher expression levels could be detected.

Conclusion
High expression levels of HGF and TGF-β1 could be detected in the BALF of the patients with ES-NSCLC with high specificity. For this reason, it has certain clinical value in the accessory diagnosis of ES-NSCLC.

Diabetes mellitus is a metabolic disorder that affects more than 220 million people worldwide.1 The prevalence of type 2 diabetes is on the rise, leading to higher levels of morbidity, workload, and cost for the National Health Service (NHS).2 In addition, the long-term complications of diabetes can also contribute to higher levels of morbidity and workload for General Practice. Community pharmacists have clinical knowledge which is being utilised to provide a range of services to patients living with long term conditions.3 These include the New Medicines Service (NMS) and the Community Pharmacist Consultation Service (CPCS) that can both support those living with diabetes by helping patients to understand their condition and use their medication correctly, reducing the need for a General Practitioner (GP) appointment. The role of the pharmacist in community pharmacy diabetes management currently has limited research.

 The aim of the study was to explore the role of community pharmacy in helping diabetic patients and thereby decrease the workload of the GP.

 This study targeted community pharmacies in Croydon (n=77) and Kingston Upon Thames (n=34) in greater London, aiming for one response per pharmacy. A survey consisting of 29 questions was crated with a mixture of tick box and free text questions. Community pharmacies were visited in both boroughs, and surveys were distributed and collected. After data collection, quantitative analysis was completed through SPSS and qualitative analysis was using thematic analysis. Ethical approval was granted by Kingston University.

 In total, 65 responses were received (59% response rate). Diabetes was found to be the long-term condition that had the greatest number of referrals to the GP (n=30/65; 46%). Referrals were mainly in response to recurrent infections and over the counter sales linked to eyes and feet. Community pharmacies provided an average of 3 advanced services, including NMS (n=63/65; 97%), CPCS (n=61/65; 94%), flu vaccinations (n=59/65; 91%) and hypertension screening (n=24/65; 37%). Some of the key themes when participants were asked about the most common issues identified in an NMS consultation with a diabetic patient, was adherence issues to their medication, lack of knowledge about diabetes and about lifestyle changes, leading to opportunities for community pharmacy-based interventions, and limiting a referral to a GP. Pharmacists felt confident in having intervention conversations and felt knowledgeable about diabetes.

 Community pharmacies are an essential part of a patient's diabetic journey, supporting person centred care. This study outlines and establishes a clear role of how community pharmacies can carry out different services for diabetic patients, be able to identify any diabetic complications in the community setting. NMS and CPCS were found to be beneficial services for diabetic patients unlocking the full potential of a community pharmacist. Although a small study in a limited geography, this study highlights that community pharmacists support diabetic patients to manage their condition, thus reducing referrals to GPs and therefore the GP workload. Future studies can be carried out over a larger area to extrapolate findings.

Objective. Dyspepsia, a common condition in the community, affects quality of life and imposes costs on both the individual and the community. Several factors including Helicobacter pylori, acetylic salicylic acid (ASA)/non-steroidal anti-inflammatory drugs (NSAIDs) use, low-dose ASA use, alcohol consumption, cigarette smoking and social status might be responsible. Material and methods. A cross-sectional study from the inclusion (intervention group) of a general population study evaluating rates of dyspepsia after H. pylori screening and eradication was carried out. A total of 10,007 individuals aged 40–64 years received questionnaires and an invitation to take part in H. pylori screening. Information on dyspepsia (the gastrointestinal symptom rating scale (GSRS) and "most bothersome symptom"), use of ASA/NSAIDs, use of low-dose ASA, lifestyle factors and level of education and employment status was obtained from the questionnaire. Dyspepsia was defined as a score of ≥2 in the GSRS dimension abdominal pain syndrome (aps), allowing for a maximum of one light problem score in any of the 3 items in the dimension to be overlooked. Results. In all, 5749/10,007 individuals participated in the study; 24.9% reported dyspepsia. In a multiple logistic regression analysis H. pylori infection was found to be a risk factor for dyspepsia, odds ratio (OR) 1.21 (CI; 1.03–1.42). However, the highest ORs for dyspepsia were: for daily use of ASA/NSAIDs 2.33 (CI; 1.72–3.15), unemployment 2.18 (CI; 2.86–2.56) and cigarette smoking ≥20 g/day 1.55 (CI; 1.29–1.86). Conclusions. H. pylori infection is a significant risk factor for dyspepsia although of less importance than ASA/NSAIDs use, unemployment and heavy smoking.

This paper reports the results of a study of magmatic rocks with Sn–W–Au–Ag mineralization from the Kuranakh, Elikchan, and Istekh ore fields in the Northern batholith belt of the north-eastern Verkhoyansk–Kolyma orogenic belt in Eastern Russia. Using petrographic, mineralogical, geochemical, and isotopic methods, we determined the mineral compositions, petrochemistry, and geochemistry of magmatic rocks, the P–T conditions of their generation and crystallization, and their geodynamic affinity. The studied magmatic rocks have common geochemical characteristics that likely reflect the influence of fluids supplied from a long-lived, deep-seated mantle source. The ore fields are characterized by Sn–W–Au–Ag–Pb polygenetic mineralization. The magmatic and metallogenic evolution comprised five stages for the formation of magmatic rocks and ores. During the first stage (Berriasian–Barremian), arc-related magmatic rocks formed in an active continental margin setting and were associated with Au–Ag mineralization. The second, third, and fourth stages (Aptian–Campanian) took place in a crustal extension and rift setting, and were accompanied by Au–Ag and Sn–W mineralization. During the fifth (post-magmatic) stage, Sn–Ag–Sb and Pb–Ag mineralization occurred.


We present a search for O I in the spectra of nine 4.9 ≤ zQSO ≤ 6.4 QSOs taken with Keck HIRES. We detect six systems with N > 1013.7 cm-2 in the redshift intervals where O I λ1302 falls redward of the Lyα forest. Four of these lie toward SDSS J1148+5251 (zQSO = 6.42). This imbalance is unlikely to arise from variations in sensitivity among our data or from a statistical fluctuation. The excess O I occurs over a redshift interval that also contains transmission in Lyα and Lyβ. Therefore, if these O I systems represent pockets of neutral gas, then they must occur within or near regions of the IGM that are highly ionized. In contrast, no O I is detected toward SDSS J1030+0524 (zQSO = 6.30), whose spectrum shows complete absorption in Lyα and Lyβ over Δz ~ 0.2. Assuming no ionization corrections, we measure mean abundance ratios ⟨[O/Si]⟩ = -0.04 ± 0.06, ⟨[C/O]⟩ = -0.31 ± 0.09, and ⟨[C/Si]⟩ = -0.34 ± 0.07 (2 σ), which are consistent with enrichment dominated by Type II supernovae. The O/Si ratio limits the fraction of silicon in these systems contributed by metal-free very massive stars to ≲30%, a result that is insensitive to ionization corrections. The ionic comoving mass densities along the zQSO > 6.2 sight lines, including only the detected systems, are Ω = (7.0 ± 0.6) × 10-8, Ω = (9.6 ± 0.9) × 10-9, and Ω = (1.5 ± 0.2) × 10-8.

An equation derived previously to describe nonlinear bubble oscillations in incompressible elastic media [Emelianov et al., J. Acoust. Soc. Am. 115, 581 (2004)] is modified to include an elastic shell with properties that are different from those of the host elastic medium. The new model equation is derived using Lagrangian mechanics. Nonlinearity is taken into account in the motion of the shell and surrounding medium, the compression of the gas, and the strain deformation in both elastic media. Two cases are considered for small but nonlinear bubble oscillations. The first applies to the case in which the equilibrium gas pressure is equal to the pressure at infinity, such that there is no equilibrium strain deformation in the medium. In this case, the Landau strain energy expansion can be used to obtain explicit expressions for the nonlinearity coefficients. For the second case, the equilibrium gas pressure in the bubble is different from the pressure at infinity, which results in strain deformation of b...

Consider the natural vibrations of elastic bodies. For the natural frequencies, we have obtained two variational principles. In the first variational principle, an allowable state is defined as follows. The stress components and their variations have the formsand satisfy the stress-free boundary conditions. The corresponding displacement components are derived from equations of motion:Then it is proved that the natural frequencies ω of the body correspond to the extreme values of the following functional: where V is the strain energy per unit volume expressed in terms of stress components.In the second Variational principle, an allowable state is defined by any continuous stress and displacement distributions, not necessarily satisfying any equation and boundary condition. In this case, it is proved that the natural frequencies ω of the body correspond to the extreme values of the following functional:where H has the expressionPx,Py,Pz are the surface tractions, and Su is that part of the surface of the body where displacement should vanish.In the last two sections of this paper, the Timoshenko's theory for the tran-sverse vibrations of beams and the Ufliand-Mindlin's theory for the flexural vibrations of plates are derived from the second Variational principle.


Pure vegetable oil fuels, used in vegetable oil compatible agricultural machinery, contribute to secure sustainable food supply. Especially rapeseed oil fuel significantly reduces greenhouse gas emissions and thus, lowers the carbon footprint of agricultural products. Harmlessness on climate and environment is guaranteed by the Directive 2009/28/EC in combination with national sustainability ordinances. Additionally, rapeseed oil fuel used for agricultural tractors features benefits such as the increase of regional added value, synergy effects with combined feed production, protection of soil and water and reduced import dependency. However, despite major advantages vegetable oil fuels are barely used in practice, because of technical, economical and sustainability concerns of potential users. It is the purpose of this work, to show the state of the art of pure rapeseed oil compatible tractors. Based upon 10 years of research with so far 14 tractors of different manufacturers and development stages (exhaust gas stage I, II, IIIA, IIIB and IV) by field tests and test stand trials, results of operational reliability, engine wear, power output, fuel efficiency and exhaust gas emissions are evaluated and compared with diesel fuel operation. Two vegetable oil operated tractors (exhaust gas stages I and II) have proved full suitability in everyday use for more than 10,000 operating hours. Apart from one defect fuel pump no failures or damages were observed. Examination of injectors and combustion chambers confirmed the good condition of both tractors. Investigation of nine further tractors (exhaust gas stage IIIA) for altogether more than 16,000 hours again showed no considerable failures or damages. Exhaust gas aftertreatment systems enabled a reliable operation with high emission reduction efficiency. Neither performance nor fuel consumption showed any deterioration during the investigated period. Generally, the limited exhaust gas components nitrogen oxides (NO x), carbon monoxide (CO), hydrocarbons (HC) and particulate mass (PM), determined at a tractor test stand by using the common 8-mode test cycle, remained at the same level. HC and PM emissions with rapeseed oil fuel are mainly lower than with diesel fuel, whereas NO x emissions are slightly higher. However, with proceeding exhaust gas stages and application of exhaust gas aftertreatment systems differences between fuels become less relevant. Positive results have encouraged the agricultural machinery industry and authorised workshops to develop tractor prototypes for both diesel and pure vegetable oil fuel operation ("flexible fuel"). Therefore, it is essential to carry on testing of latest technologies with pure vegetable oil fuel. Furthermore, enhanced public relation work, reliable framework conditions and initial incentives can pave the way for a reasonable decarbonisation of agricultural production.


Our first-principles study demonstrates for the first time that by increasing the molecule-surface binding strength, the interlayer magnetic coupling of a ferromagnetic metal can be drastically reduced with respect to that of a clean substrate. Importantly, for a weakly chemisorbed molecule the rehybridization of metal atomic d states within the molecule-induced surface geometry (geometrical effect) plays a crucial role in obtaining interlayer magnetic softening. On the contrary, for a strongly chemisorbed molecule the interlayer magnetic coupling is further reduced due to an interplay between the geometrical effect and the hybridization of atomic d states with molecular ones.

The purpose of this article is to clarify the nature of legal professions as experts. In particular, an attempt has been made to answer the question of what, in the case of these professions, is the social role that requires the application of abstract knowledge to specific cases. The starting point for consideration is social theories that see this role as a mediation and integration of the social structure. Next, using the methodology of cognitive metaphor, this characterization is further clarified by juxtaposing it with another type of expert activity, i.e., translation. Thus, practical problems were identified in the work of a lawyer, related to mediating in the social structure between abstract knowledge of law and solving individual legal problems. These problems were characterized primarily as difficulties in the use of different languages by institutions and citizens.


Almost all the inscription on bronze mirror of the Han Dynasty are written in poetic language and form,among which one is complete"seven syllable"verse.The formation of seven syllable verse that inscribed on bronze morror can be traced back as early as the mid Western Han Dynasty.This verifies the fact that there were rapid development of "seven syllable"style at that time and negates the saying that "there seemed no relable or complete "seven character"ballads before the Han Dynasty".The formal characteristics of "seven syllable"verses inscription indicates that it was experiencing a transitional phase from ballads to the imitative works of literati.It is the product of ballads variation featured by seven syllable syntax.


Barbier-type reactions represent a classic reaction type for carbon-carbon bond formation. However, the commonly used stoichiometric metals still hamper their wide application. Considering easy availability and diversification of cyclic amines, herein, we report a visible-light photocatalytic Barbier-type reaction of aziridines and azetidines with unactivated aldehydes. A series of important γ- and δ-amino alcohols are synthesized in the presence of amines as electron donors. What's more, this transition metal-free protocol displays mild reaction conditions, good functional group tolerance and broad substrate scope. Mechanistic investigations indicate that carbon radicals and carbanions might be generated as the key intermediates.

support for "change," its commitments to traditional cultural values, and its conception of the current condition of the welfare state as simply a problem of fiscal balance, the last chapter is neo-conservative to the core. But this is a neo-conservatism triumphant, comforting its more anxious ideological fore bearers with the good news that their concerns about a fundamental crisis of values and legitimacy are unnecessary. The ideology is, however, initially well disguised by the empiricism, and by the apparently comprehensive sweep of the attack. A "'nothing but the facts, ma'am," plain common sense is pitted against a diverse collection of commentators: the "social critics" (Reich, Roszak, Toffler), the theorists of the "real majority" (Scammon and Wattenberg), the "workplace critics" (Braverman, Aronowitz), the "workplace researchers" (Kahn, Quinn), the "post-industrialists" (Bell, Inglehart) and the "intellectuals of the little man" (Hamill). All are treated with scornful dismissal for failing to respect the facts. There is something of a straw-man quality to some of these selections, and there are a number of significant critics of contemporary American society omitted. Many of the arguments in the best work selected cannot be conclusively tested with the survey data examined here, and many of the telling points in this book (for example, against Inglehart and the workplace critics) are made in the original "quality of life" literature. Hamilton and Wright nevertheless make a damning indictment of the lack of attention to relevant data in much that passes for social science, and they give admirable precision to a number of parameters of ideological structure in the US: the stark contrast between extensive satisfaction in the sphere of private life and the equally widespread dissatisfaction with public affairs; the fundamental stability of public opinion on broad issues of social policy, and the absence of any clearly marked swing to the right; the internal tensions between libertarian and egalitarian principles in the structure of public policy attitudes; the encapsulation of individual experience within family life, the predominant effect of life-cycle changes on consciousness, and the limits to economically induced discontent as compared to the satisfactions of real and expected mobility. This is documentation that should substantially enrich political analysis. It is a pity, therefore, that Hamilton and Wright's substitution of ideology for analysis will put off many who might otherwise profit from their book.


OBJECTIVES
To evaluate the performance of magnetic resonance elastography (MRE) in staging liver fibrosis in patients with histologically confirmed nonalcoholic fatty liver disease (NAFLD) and to assess the impact of potential confounding factors in MRE diagnostic accuracy. Secondary objective was to compare MRE with other non-invasive methods for staging fibrosis such as transient elastography and non invasive scores(APRI and FIB-4) Methods: Sixty-five histologically confirmed NAFLD patients were prospectively enrolled at 'Virgen del Rocío' University Hospital (Seville). Liver stiffness was measured by MRE, transient elastography and non invasive scores(APRI and FIB-4). Fibrosis was assessed by liver biopsy using SAF score. We classified patients into 3 groups according to the consistency between MRE and histopathological findings: underestimation, concordance and overestimation group. Areas under the ROC curve (AUROC) and diagnostic performance were evaluated.

RESULTS
The area under the ROC curve (AUROC)of MRE in advanced fibrosis(≥F3) was 0.90[0.82-0.97], while transient elastography AUROC was 0.82[0.72-0.93](p=0.22) and lower for non-invasive test(FIB-4 0.67 and APRI 0.62). Inflammatory activity, steatosis grade and higher levels of liver biochemistry appeared to overestimate MRE results in univariate analysis, but only GGT was statistically significant in the multivariate analysis(p<0.01). Age, sex, BMI, weight, DM, HTA, platelets or lipidic profile did not affect MRE accuracy.

CONCLUSIONS
MRE is an effective and non-invasive method for detecting and staging liver fibrosis in NAFLD patients. MRE is more accurate than transient elastography and allows the study of liver anatomy. Histological inflammation and surrogate biomarkers of inflammation can overestimate liver stiffness, but only GGT was statistically significant in the multivariate analysis. Important features of NAFLD patients such as obesity, Mellitus diabetes, or lipidic profile did not affect MRE accuracy.


The highly conserved influenza fusion domain (HAfp) is a strict requirement for fusion of the viral
membrane with the host endosomal membrane. This step of the infection process is vital for influenza
proliferation. HAfp is a highly conserved peptide with a unique amphipathic helical-hairpin structure.
This thesis describes a broad investigation into the precise mechanism by which HAfp induces
membrane fusion. Here we demonstrate that HAfp is capable of inducing negative membrane curvature
correlated to its ability to promote fusion. This ability appears to be the result of a unique conical shape
and a particular orientation of membrane insertion. Additional mutational studies reveal that such
fusion induction is sensitive to even conservative mutations, which demonstrate varying effects on HAfp
structure and dynamics. These mutational studies suggest that wildtype HAfp activity is highly nuanced,
with refined features such as tertiary dynamics, overall geometry, binding kinetics and depth or angle of
membrane insertion. This delicate balance relates well with the high degree of evolutionary
conservation and may play an important role in the development of therapeutic measures.


This article analyses community-based tourism (CBT) as a methodology of work that aims to improve the livelihood of the communities that choose this activity as an economic development strategy. Using examples from Brazil, the objective is to address methodological questions about the developmentstages as well as issues pertaining to access to markets, governance and monitoring.These case studies demonstrate that in order to achieve and maintain the sustainability of community-based tourism programsthe presence of tourism associations and cooperatives that fomented initiatives of cooperation and institutionalization has been vital. Due to the complexity and existing variables that are bot h implicit and linked with tourism activities in communities, this article also provides suggestions to increase the


The current study examines the value correlates of social identities (identification with in-groups and geospatial units) in two collectivist cultures (Brazil, n = 471; Spain, n = 476). According to previous research, it was expected that subjects who score higher on social values would be more identified with the various traditional in-groups and with the local geospatial units and that social identities would be predicted by different values among Brazilians and Spaniards. Subjects were undergraduate students (228 males; 719 females), with age ranging from 16 to 55 years (M = 21.9; SD = 4.57), from three states in Brazil (Paraiba, Distrito Federal, and Sao Paulo) and Spain (Pontevedra, Madrid, and Barcelona). They were administered the Individualism-Collectivism Questionnaire, the Basic Value Survey,the In-group Identification Scale, the Geospatial Identification Scale, and a questionnaire with demographic questions (e.g., gender, age, religious affiliation). Results confirm that importance attributed t...


The ability of students to segment the speech stream into phonemic units and to analyze (make judgments as to same or different) beginning consonant phonemes was assessed at grades kindergarten through third from both high and low socioeconomic groups. Segmentation ability was assessed by the use of a test of actual words in a match-to-sample task, a test of synthetic words requiring a same-different judgment and a task which required deletion of a phoneme from a known word to form a new word. Three prerequisite abilities were also assessed: auditory acuity and understanding of the concepts "same" and "different" with regard to sounds, and "beginning" with regard to sequence of sounds.


The invention relates to a single-coil permanent magnet releaser comprising a permanent magnet and a dynamic iron core, wherein the dynamic iron core is matched with the permanent magnet, the outer ring of the dynamic iron core is wound by a single coil, and the single coil is connected with a driving circuit which changes the current direction of the single coil. The invention realizes switching-on and release functions of the permanent magnet releaser by changing the inner current direction of the single coil, thereby not only saving the cost, but also having simple structure; thus the invention is suitable for large-scale production.

In this paper a modification of the estimative prediction limit is derived, for which the coverage probability equals the target value to third-order accuracy, under ordinary repeated sampling. It provides an explicit approximate solution to the equation given by Barndorff-Nielsen & Cox (1996), which determines an upper α-prediction limit for an unobserved random variable. The corresponding predictive density is specified in a simple closed form and its main properties are emphasised.

OBJECTIVE
To investigate the meaning of acting with others, in different places over the course of 1 year post-stroke.

METHODS
Qualitative interviews with 9 persons, age range 42-61 years (7 persons with cerebrovascular accident and 2 with subarachnoidal haemorrhage) over the course of a year (i.e. 3, 6, 9 and 12 months) were analysed using a grounded theory approach.

RESULTS
Four categories were identified from the analysis of the participants' experiences during the year of rehabilitation: (i) not recognized as the person I am; (ii) the burden of burden; (iii) inspiration and belonging through acting with others; (iv) reality adjustment through acting with others. From these categories a core category emerged: a process of belonging for integration.

CONCLUSION
The 4 categories identified suggest that belonging is integral to participation, which is viewed as the goal of rehabilitation.


The invention discloses a preparation method of a nanowire structure. The preparation method comprises the following steps of: depositing metal films on the surfaces of two side walls of a polycrystal semiconductor layer, wherein metals in the metal films are diffused towards the surfaces of the side walls of the polycrystal semiconductor layer; and after annealing, forming metal semiconductor compound nanowires on the surfaces of the side walls of the polycrystal semiconductor layer. In the preparation method of the nanowire structure, the nanowires are formed without a high-resolution-ratio photoetching technique, so preparation cost is greatly saved. The prepared metal semiconductor compound nanowire can also serve as a mask and transfers the nanostructure figure to the next layer of structure, so that preparation of the nanowire structure is facilitated.


The aim is to study the demand for organic products and to determine the consumers' willingness-to-pay (WTP) for the organic characteristic. An Almost Ideal Demand System is used to estimate the demand for organic products. We obtain observed data (scanner data) thanks to the co-operation with Auchan distribution group, then we use an indirect valuation method based on invariance situations of the expenditure function to calculate the willingness-to-pay.

We study the Cauchy problem for a parabolic partial differential
equation with a power nonlinearity.
It was shown in our previous paper that in some parameter range, the problem
has a time-local solution with prescribed moving singularities.
Our concern in this paper is the existence of a time-global solution.
By using a perturbed Haraux-Weissler equation, it is shown that there exists
a forward self-similar solution with a moving singularity.
Using this result, we also obtain a sufficient condition
for the global existence of solutions with a moving singularity.


Challenging infrared data sequences such as the well-known AMCOM closure sequences are characterized by highly nonstationary evolutionary target and clutter signatures, poor target-to- clutter ratios, and complex kinematics arising from both the target motion and the motion of the sensor platform itself. In such cases, track consistency checks can provide a valuable means for detecting an imminent track loss. In this paper, we consider a simple target model with a correlation-based detection process and a straightforward SIR particle filter track processor. We show that the performance of the track processor can be dramatically improved by incorporating modulation domain consistency checks to identify failure in the correlation-based detection process. This strategy results in a robust dual-domain tracker that, despite the simplicity of its state model, delivers superior tracking performance against the very difficult AMCOM sequences.


A focus of geography is the study of complexity: we include many interacting processes when we study places. Another view of complexity in geography is that complex pattern, in particular spatial pattern, can arise from few or simple interactions, if they are nonlinear. Environmental responses to global change are likely to be nonlinear and thus complex. Shifts in ecotones–the boundaries of vegetation types or biomes–may be indicative of such complex response to global change. One reason for expecting nonlinearity is that positive feedbacks may play a strong role in determining the conditions for the establishment and growth of trees. A spatially explicit computer simulation is used to examine the effects of feedback strength, seed rain and establishment, and rate of environmental change as might occur at a mountain treeline ecotone. Changes in presence and abundance of trees exhibit nonlinear responses to environmental change during a transient period. The implications of nonlinear responses are that surprises are more likely than precise prediction. [Key words: complexity, ecotone, Rocky Mountains, treeline.]

Summary An investigation to assess structural gene variation in brown trout populations from Northern and Central Apennines was carried out. Combined analyses of 16s rDNA haplotypes and LDH-C1* genotypes demonstrated the limited presence of autochthonous strains of Mediterranean trout in all investigated streams. Pure Mediterranean trouts were 21% of overall sampled specimens in Northern Apennine (12 sampling stations) while most of trouts were genetically attributed to hybrid individuals. Experimental data allowed the elaboration of an innovative introgression index based on the combination of mitochondrial haplotypes and nuclear alleles. The research was also extended to the characterization of spawners to be used for artificial insemination and restocking of Central Italy streams. Genetic selection of 95 spawners has allowed to obtain a pure Mediterranean strain (100% individuals) in the F 1 generation.


The work in this paper reports on an heuristic based computer tool directed at casting process design; in particular key design parameters, such as part orientation, location of sprues, feeding rates, etc. The underlying principal used is that a given casting can be represented on identifying and classifying its critical features. The input to the system consists of the attributes of the features and the graphical output provides semi-quantitative information on key design parameters. Results on real castings match those of the expert casting designers and in some cases potential design improvements have been suggested by the system.

ScS and sScS phases recorded by the long-period seismographs are analyzed to study the attenuation of shear waves in the upper mantle beneath the Sea of Japan. Data from the Vladivostok deep-focus earthquake of September 10, 1973 are used. The value of Qβ', the average Qβ for the mantle above the hypocenter (depth=552km), is about 70 for the frequency range of 0.02-0.07cps. This value is lower than those of some of previous estimates in and around the Japanese region, but is consistent with QR, Q of Rayleigh waves, for the trench and marginal sea region obtained from the "pure-path" analysis of long-period (T=200-300sec) Rayleigh waves. It is emphasized that the signal-to-noise ratios should be taken into account to obtain an unbiased estimate of Q.

This article discusses an object-oriented approach to industrial software development using Mathematica. We present the package Elements for structured representation of physical, engineering, and mathematical objects. This package introduces object-oriented paradigms into Mathematica and is used to develop a modeling environment built on a knowledge base where class and object properties and relations are maintained in a consistent, transparent, and extensible way. We show how this tool can be applied to design models parametrized by structured objects instead of just simple values.


We read with great interest the results of Liao et al reporting that standard-dose intravenous tissue-type plasminogen activator (tPA) for stroke had more favorable outcome than low-dose tPA without increasing the risk of symptomatic intracranial hemorrhage (SICH).1 They concluded that 0.9 mg/kg should be the optimal dose of tPA for Asians to treat acute ischemic stroke.

The authors in the study reported there was no significant difference in the rate of SICH between 0.5 to 0.7 and 0.85 to 0.95 groups; and SICH in 0.7 to 0.85 group was even greater than in 0.85 to 0.95 group. For functional independence (mRS, 0–2) at 3 month, 0.7 to 0.85 mg/kg group did also significantly worse than 0.85 to 0.95 mg/kg group. However, they evaluated and compared the safety and efficacy only with analysis adjusted …


I HAVE BEEN dismayed at the uncritical acceptance of international comparisons in this country. It seems to me that otherwise competent researchers and psychometricians abandon all critical faculties when dealing with data from the International Association for the Evaluation of Educational Achievement -- the TIMSS studies and PIRLS -- or the Organisation for Economic Co-operation and Development (OECD) -- PISA. Technically put, they go gaga. Clearly, there is political pressure to accept these studies, but I also see them as a small growth industry on which a number of careers depend. Aside from my own analyses (Kappan, May 1998; Kappan, September 1998; and Educational Researcher, May 2000), I know of only three other pieces -- two by Jianjun Wang (Kappan, November 1996; and Kappan, September 1998) and one by Erling Boe and Sujie Shin (Kappan, May 2005) -- that take a more reasoned look at the studies. I had to tone down the Educational Researcher article to meet the requirements of the dullness police. Maybe I should move back to Europe, where there are much livelier and more skeptical discussions of these studies. To provide a peek about what's being said across the pond, I've gone through my towering to-be-read pile and extracted commentary related to PISA 2000 (Programme for International Student Assessment 2000), the first of the PISA assessments. In conference notes, Emma Nardi of the University of Rome wrote that one could not say much about "Italy" from the results because "Italy is a country new to education, unlike France, where education has been a reality since the French Revolution. We have not yet succeeded in overcoming the fragmentation due to our belated unification declared in 1861." Nardi also noted that there were so few foreign students in the Italian results that possibly the sample was improperly drawn. The French, not doing as well on PISA as they had in earlier international comparisons, generally slammed it as another manifestation of Yankee Imperialism, now referred to as the "Anglo-Saxon model." That model includes the imposition of national rankings and standardized tests. Marc Romainville of the University of Namur, in French Belgium, penned a widely read critique in the journal Nouvelle Revue. Romainville first called PISA a "projective test," similar to a Rorschach, in which everyone sees what their own idiosyncratic needs determine that they see. But, he continued, "All this could be dismissed if the dominant tone of the media treatment were not working to harm the already quite eroded public perception of teachers. The most disturbing, taking all things together, is that once again opprobrium has been heaped, indiscriminately, on the thousands of teachers who, day in, day out, and in difficult circumstances, try to teach and hear it said, in response, that their teaching is 'ineffective and inequitable.'" Romainville then takes to task the very idea of producing a results "league table" (country-by-country rankings): Hit parades have been flourishing here for some years: the best schools, the world's best universities, the top-performing research centers, etc. Some 30 years ago this sort of ranking would have produced a smile, as we were of the view that the broad and long-term effects of education cannot be reduced to a few trivial indicators and that every education system could be validly understood only by taking account of its history, its aims, and the complexity of its structures. This craze for rankings derives, Romainville argues, from "the increasing grip of the Anglo-Saxon model." He continues, "PISA avoids neither this ranking delusion nor the domination of the Anglo-Saxon model . . . the actual development of the tests was the responsibility of an Anglo-Saxon consortium of Australian, Japanese, U.S., and Dutch organizations." Romainville conjectures that this consortium first prepared a master test in English, then translated it into French because OECD, the sponsoring organization, is officially French-English bilingual. …


Galleries and museums were key to the development of the public sphere in nineteenth-century Europe and America; museums of design and applied arts had an additional mission, namely, to promote economic competitiveness by improving the quality of design. This story is well known in relation to museums in London, Vienna, Berlin, and Paris. But what role did museums outside of the capital cities play? This article analyzes the growth of museums of design in Bohemia and Moravia in the late nineteenth century, focusing on the Moravian Design Museum in Brno. It considers what happened when ideas about museums and their public purposes encountered the forces of municipal politics. Rudolf Eitelberger (1817–85) founded the Austrian Museum for Art and Industry in Vienna as a means of disseminating a shared idea of aesthetic and cultural value, but how successful was this idea in gaining acceptance outside of Vienna?


We have developed a powerful and efficient method for locating the event horizon of a black hole spacetime, making possible the study of the dynamics of event horizons in numerical relativity. We describe the method and apply it to a colliding black hole spacetime.


The observation that testicle extract markedly enhances the infectivity of certain viruses and bacteria, reported by one of us (DuranReynals (1)) has been confirmed and extended by a number of investigators (2). I t has been further shown that testicle extract exerts an inhibitory influence on the growth of a transplantable epithelioma of the rabbit (3) and to a less extent on a sarcoma of the mouse (4). I t is of interest to know what effect testicle extracts will have on the chicken neoplasms, transmissible by cell-free extracts. Recently Hoffman, Parker and Walker (5) have published the results of a similar investigation in which they report evidence of the enhancement of the chicken tumor agent by rabbit testicle extract, but none by that from rooster testicle. This evidence is based on two positive experiments, but the same testicle extract was used in both tests. They draw no conclusions as to the nature of the tumor agent from these results, but give the impression that further investigation with the method might lead to some conclusions on the question. During the last 3 or 4 years a considerable amount of data had been accumulated in this laboratory, but had not been published at the time the article referred to appeared. Since our results dif" fered from those reported by the above authors, we deferred publication until additional tests could be made with certain minor modifications in technique suggested by their paper.


Introduction: Nurses have a limited knowledge of the PA profession. Nurses familiar with physician assistants conceptually, or from first-hand experience, are more likely to have positive attitudes toward them. Through early placement of interdisciplinary education, favorable attitudes toward the physician assistant profession will develop during nursing curricula. Objective: The objective is to discover knowledge and attitudes of undergraduate nursing students toward the PA profession. The knowledge and attitudes were assessed before and after a short informational session. Methods: The study examined knowledge and attitudes of undergraduate nursing students on the PA profession in a brief pre-test/post-test design. Results: Research hypothesis shows statistical differences in attitudes and knowledge of nursing students supported by a McNemar test. Conclusion: The study revealed that a short presentation on the physician assistant profession increased knowledge and helped contribute to attaining positive attitudes toward it.


The alarming increase of ambient ozone (O3) levels across China raises an urgent need in understanding underlying mechanisms of regional O3 events for highly urbanized city clusters. Sichuan Basin (SCB) situated in southwestern China has experienced severe O3 pollution at times in summer from 2013 to 2020. Here, we use the WRF-CMAQ model with the Integrated Source Apportionment Method (ISAM) to investigate the evolution mechanism and conduct source attribution of an extreme O3 episode in the SCB from June 1 to 8, 2019. This typical summer O3 episode is associated with the synoptic-driven meteorological phenomenon and transboundary flow of O3 and precursors across the SCB. Weak ventilation in combination with stagnant conditions triggered the basin-wide high O3 concentrations and enhanced BVOC emissions substantially contribute up to 57.9 μg/m3 MDA8 O3. CMAQ-ISAM indicates that precursor emissions from industrial and transportation have the largest impacts on elevating ambient O3 concentrations, while power plant emissions exhibit insignificant contributions to basin-wide O3 episodes. These results improve the understanding of the summertime O3 episode in the SCB and contribute insights into designing O3 mitigation policy.


Recent work introduced a unified framework for steerable and directional wavelets in two and three dimensions that ensures many desirable properties, such as a multi-scale structure, fast transforms, and a flexible angular localization. We show that, for an appropriate choice for the radial window function, these wavelets also have closed form expressions for, among other things, the spatial representation, the filter taps for the fast transform, and the frame representation of the Laplace operator. The numerical practicality and benefits of our work are demonstrated using signal estimation from non-uniform, point-wise samples, as required for example in ray tracing, and for reconstructing a signal over a lower-dimensional sub-manifold, with applications for instance in medical imaging.

High expectation surrounds pregnancy and birth, not only for physical safety but also for emotional fulfilment. Each labour is a unique event and many differ considerably from the experience the woman expected. It is a commonly held belief that the pain and distress of labour is quickly forgotten once a woman holds her healthy baby in her arms. For some women, however, this is not the case. Questions and emotions not dealt with at the time can surface later to cause problems which could affect the woman's physical health, increase the likelihood of postnatal depression and interfere with good parent-infant relationships. This article aims to examine the role of labour debriefing by midwives in the provision of good psychological care.


Novel block copolymers were synthesized in a controlled fashion by nitroxide-mediated radical polymerization starting from a terpyridine-modified alkoxyamine. An important feature for controlling the efficiency of the polymerization is the presence of excess nitroxide, responsible for the initial rate of deactivation, which eventually leads to a decrease of the polydispersity indices of the desired block copolymer. The materials obtained were characterized by means of 1H NMR, UV-vis spectroscopy, and GPC. The complexation of the terpyridine ligands resulted in the formation of A-B-[Ru]-C, A-B-[Ru]-B-A, and A-B-[Fe]-B-A metallo-supramolecular block copolymers. -© 2006 WILEY-VCH Verlag GmbH & Co. KGaA


The article presents the results of research on the realization of the adaptive, productive and reproductive potential of pigs by immunoprophylaxis of transport stress with Pigstim preparations. The transport stress prevention for replacement gilts with immunotropic drugs PigStim-C and PigStim-M contributed to their adaptive and reproductive potential realization by reducing the age of first insemination by 7.7-9.0 days and increasing its fertility, increasing the number of liveborns by 6.8-8.5% and reducing the number of stillborn piglets by 50 and 25%, increasing the viability by 1.72-3.32% and growth rate of piglets during the suckling period by 2.9- 4.0% and reducing the weaning-to-insemination period by 6.4 and 8.5%. The immunoprophylaxis of transport stress in weaned pigs ensured their adaptive and productive potential in long-term growing completion and store feeding period by increasing the live weight of stores by the end of growing completion by 1.66 and 2.55 kg and feeding period by 1.23 and 3.17 kg, reducing the incidence by 5.0 and 4.0% and increasing the viability of the livestock by 2.0%, increasing the effectiveness of therapeutic measures.


Presented paper utilizes a reasonable boost converter setup and a PI controller for a Wind Turbine connected to Permanent Magnet Synchronous Generator (PMSG) for grid coordinated operations. In view of inconstant flow of wind, wind turbine generator produces variable-voltage and variable frequency. A few unique strategies were utilized to change variable-voltage, variable-frequency to reliable constant-voltage, constant-frequency outputs. In variable speed operation, it is important to utilize power electronics converter as an interface between wind turbine and grid. Power converter comprises of an uncontrolled three-phase diode rectifier, a DC-DC boost converter and a three-phase inverter. In this work, PMSG which feeds an isolated load through a closed loop boost Converter maintaining constant output with reference value as error signal input to PI controller using Cohen-Coon tuning method. In this PI controller, DC link voltage is maintained at constant by varying duty ratio of switch and continuously detecting output voltage. Together with controller and boost converter we can effectively enhance output voltage and frequency of generator feeding isolated load. The overall system is simulated using MATLAB/ Simulink and results are compared with theoretical results.
