Herein, we reported a new strategy based on self-assembly chemistry for chiral discrimination of glucose on a new S-mandelic acid-appended calix[4]arene (S-MC4) modified nanostructure, which exhibits macroscopic chiral preference for d-glucose via contact angle measurements (CA). The proposed macroscopic chiral device displays rapidly remarkable specificity and is convenient to use, which should be suitable for diagnostic purposes, nanomedical applications, etc.


Northwest-trending basins cutting across older northeast-trending facies belts in eastern California opened by Middle Pennsylvanian time and continued to develop and expand into the Early Permian. Basin development was accompanied by east-vergent thrust-faulting in the Early Permian and was followed by development of northeast-trending folds and regional uplift in middle and Late Permian time. These events have been considered products of long-tern sinistral truncation of the western North American continental margin. Later, in the Late Permian, extensional faulting created small northeast-trending basins in which deposition of terrestrial and shallow-marine rocks occurred. The author consider all late Paleozoic tectonism in eastern California to have been driven by plate interactions along the western margin of North America and to be only indirectly related to the late Paleozoic collision between North America and Gondwana. They propose that the truncated part of North America was part of the Paleo-pacific plate. In Nevada the margin of this plate, along which the Havallah assemblage eventually was emplaced, was convergent, but in California the margin bent sharply and became transform. This fault continued as the Mojave-Sonora mega-shear into Mexico where the oceanic part of the Paleopacific plate was subducted under Gondwana, forming an extensive arc now representedmore » by rocks in S.

A computational theoretic approach is adopted to show that the thalamic dis-inhibitory pathway of an alert cat strengthen the retinal ganglion cells' inhibitory surrounds at the dorsal lateral geniculate nucleus. First, a criterion is introduced to evaluate the sharpness of a two-dimensional activity pattern of cells residing at a rectangular lattice. Then, a parallel iterative algorithm is introduced as the computational mechanism of the dLGN circuitry. Probed by an activity pattern, the algorithm evolves in order to maximize the sharpness criterion. Finally, a modular neural network compatible with the known circuitry of the cat's thalamic dis-inhibitory pathway is introduced to implement the algorithm.


Fine-tuned crystallinity and optimized morphology were achieved by incorporating 2-dimensional monomer into N2200 resulting in enhanced PCE in various donors-based OSCs and improved device stability.


The landslide from the east face of Turtle Mountain that destroyed the southern end of the town of Frank in the Crowsnest Pass area of southwestern Alberta has become a classic example because it is one of the largest for which eye witness accounts and a contemporary scientific examination exist. Textbook accounts rely on the reports published shortly after the slide's occurrence in 1903.The slide was thought to have moved down the dip of a steeply inclined set of joints and has therefore been classified variously as a rockfall or block flow. Later regional and geological mapping has shown that the crest of Turtle Mountain lay close to the axis of the Turtle Mountain Anticline. A new detailed map shows that the slide mass lay on the steeply eastward dipping limb of the anticline and the crest of the fold lay very close to the crown of the slide. The slide probably took place on bedding surfaces with the orientation of the scarp and lateral margins of the slide controlled by joint sets. The surface of rupt...


Turkeys (Meleagris gallopavo) were domesticated in Mexico between 200 B.C. and 700 A.D.; neither date nor location are precisely established. The wild ancestor was the Mexican subspecies (M. g. gallopavo). Two breeds of turkeys, different from those of Mexico, were being raised in pre-Columbian southwestern USA. Where did they originate? How do they relate to the Mexican domestication? Mexican turkeys were taken to Europe immediately after the discovery, perhaps as early as 1500. Diffusion through Europe was very rapid and by mid-16th century they were no longer a curiosity. Rate of diffusion is estimated at 40-50 km/yr. By comparison chickens moving from Asia to Europe in ancient times had a rate of 1.5-3 km/yr. Natural increase from a few founders cannot account for the rapid spread of turkeys. Were large numbers sent to Europe following discovery? Colonists brought turkeys from Europe to eastern North America early in the 17th century. The birds hybridized with the eastern wild turkey (M. g. silvestris) resulting in the American Bronze breed, the foundation of modern commercial turkeys. Does any of the original Mexican stock still exist in Europe or in the Americas. Similar questions are posed regarding preColumbian muscovy ducks (Cairina moschata) and chickens (Gallus domesticus).


We thank Dr. Bernardi et al. [1] for their comments and efforts on our work about the prediction of regrowth after radiofrequency ablation (RFA) for benign thyroid nodules. Since RFA has been considered as an alternative to surgery, the long-term efficacy has attracted research attention. In our previous study, residual vital ratio (RVR) was determined to early predict nodule regrowth after RFA for benign thyroid nodules. It was the initial ratio of residual vital volume to the total volume after RFA. Because the total volume of nodule after ablation could be divided into the ablate volume and vital volume (Vv) [2], the equation of RVR were as follows: RVR1⁄4Vv/Vt 100%1⁄4(Vt Va)/Vt 100%. Our results showed that RVR was the independent factor associated with regrowth by multivariate logistic regression analysis. The AUC for RVR to predict regrowth was 0.819 with a cutoff value of 44.5%. Dr. Bernardi et al. further evaluated RVR predictive value for clinical outcomes after five-year RFA. The results showed that RVR had a moderate accuracy in predicting technique inefficacy and a good accuracy in predicting retreatment, but no discriminative value for regrowth. There were several reasons to explain the different results from two studies. The most important one was that the measurement methods of RVR in the two studies were different. In our study, Vt was measured by conventional US and Va by contrast-enhanced ultrasound (CEUS). After reading the study of Dr. Bernardi et al. [3], we found that only conventional US was used for the measurements. However, the margin between the ablated area and incomplete vital area was ill-defined or irregular on conventional US [4]. Schiaffino et al. [5] showed that CEUS had higher reproducibility and interand intra-observer agreement compared to conventional US in the assessment of Va measurement after RFA for benign thyroid nodules. Our recent study also observed similar results [6]. The results found that Va measured by conventional US was significantly larger than measured by CEUS. The intraand inter-observer reliability and agreement between conventional US and CEUS in measuring Va decreased over the follow-up period. The best agreement was found at 1month with a mean difference of 1.156 and LOA of 0.453 to 2.948. It means that compared with CEUS, the measurements of Va were overestimated by conventional US. Meanwhile, for about 95% of cases, the measurements by conventional US were between 0.453 and 2.948 times the measurements by CEUS, which was much larger than the clinical criteria (0.5–1.5) [7–10]. These results indicated that conventional US could be neither reliable nor provide equivalent results compared to CEUS in the measurement of Va. Because of the larger Va measured by conventional US, RVR could be underestimated. It could have an impact on the evaluation of regrowth and explain the different results from these two studies. Second, we agree with Dr. Bernardi that the discrepancy could also be related to the heterogeneous follow-up length. Sim et al. [2] found that there were two peaks of nodule regrowth after ablation. First peak began at 12months after ablation and tended to be prominent at 2 years, and the second one appeared later than 5 years. However, the followup period in our study was only 22.50 ± 13.29months, the value of RVR on the second peak of regrowth is further prospective investigation. Third, both studies were respective, and the clinical characteristics were different. In their study [3], 66% of the nodules were nonfunctioning and 34% of the nodules were autonomously functioning. The nodule structure was solid in 44% of cases, predominantly solid in 35% and predominantly cystic in 21% of cases. However, in our study, the nodules were all nonfunctioning and structure was solid and predominantly solid nodules. No predominantly cystic nor autonomously functioning thyroid nodules were included. In conclusion, accurate detection and measurements of the true volume was essential for successful evaluation [11]. Compared with conventional US, CEUS was a superior method for detection of microvasculature circulation dynamics and is useful for precise definition of the size and margins of the necrotic zone induced by thermal ablation [12,13]. For precise prediction of regrowth after RFA, CEUS needed be used for the measurement and calculation of RVR.

Within 7 d, small honey bee ( Apis mellifera L.) colonies that consumed low levels of methamidophos in sugar syrup lost more eggs and larvae than control colonies, without conspicuous loss of adult worker bees. Youngest brood and brood at the transition between developmental stages were most sensitive. Development of surviving brood was not slowed appreciably by colony consumption of methamidophos. Environmental variables affected the sensitivity of brood to the pesticide. Colonies observed over a 13-wk period recovered rapidly and completely from a single 2.0 mg/liter treatment, without residual effect on uncapped brood, capped brood, honey storage, or queen survival. Larvae were more sensitive than queens, and adult workers were least sensitive. Brood and queens were less sensitive in small colonies than in large colonies. Implications for the mechanisms of pesticide damage to brood rearing and for remedial actions by beekeepers are discussed. The techniques described are effective for short-term and long-term studies of pesticide consumption on brood rearing and queen survival.


Cadmium is one of the most toxic trace metals and induces high concentrations of the metal-binding polypeptide phytochelatin, (γ-Glu-Cys)nGly where n ≥ 2, in the marine diatom Thalassiosira weissflogii. Here we show that at high inorganic cadmium concentrations there is an efflux of cadmium from T. weissflogii so large that over half the cadmium taken up by the cell is returned to the medium. At high inorganic cadmium, there is also an efflux of phytochelatin from the cell. The efflux of both cadmium and phytochelatin stops when the external inorganic cadmium concentration is reduced. The efflux of phytochelatin and cadmium occurs at a molar ratio of approximately 4 γ-Glu-Cys subunits per cadmium, a stoichiometry similar to that measured in vivo for the cadmium−phytochelatin complex. We hypothesize that T. weissflogii exports the phytochelatin− cadmium complex as a detoxification mechanism. The cadmium−phytochelatin complex does not appear to be very stable in seawater once outside the cell since the cadm...


Pregnancy and motherhood bring enormous change to one's life. As a student of philosophy, I have struggled to find a place for myself, as a new mother, in academic life. Jean-Paul Sartre's Being and Nothingness examines human consciousness -- it places human experience as the starting point of philosophical inquiry. This approaches the sort of place I think human experience should rest in philosophy. If I am to claim that motherhood is academically significant, surely, this examination must begin with an examination of human experience. This paper tries to root my experience of pregnancy as something that I think is academically interesting. It was through writing this paper that I found myself hopeful that my becoming a mother was not the end of my academic career, but rather presents an interesting and important new path in my philosophical journey.


The article describes a method for clustering rural areas has been developed that involves building a composite index based on the aggregation of six individual indicators that comprehensively characterize the level of agricultural development. Regional differentiation of the calculated index values allowed us to identify five typological groups within which it is possible to trace the correlation between the level of agricultural development and population density. The first group included twenty-one subjects of the Russian Federation located in the European part of the country, with the most developed agriculture and a predominantly higher density of rural population in comparison with neighboring regions. The second group includes 24 subjects of the Russian Federation (including the most populated North Caucasian republics – Dagestan, Ingushetia, Kabardino-Balkaria) with a range of index values from 0,501 to 0,550, corresponding to developed agriculture. The third group includes 26 subjects of the Russian Federation with a range of index values from 0,401 to 0,500, indicating the average development of agricultural production, which is largely a consequence of the general socio-economic problems of the regions. The fourth group includes 5 subjects of Siberia and the Far East With a range of values of the complex index 0,351-0,400, which are characterized by unfavorable ground-climatic conditions that objectively limit the development of agriculture and rural territories. Six regions complete the rating, some of them belong to the Northern territories with unfavorable climatic conditions (Murmansk region, Nenets district, Yamalo-Nenets district), some are outsiders in terms of socio-economic development (Republic of North Ossetia-Alania, Republic of Altai, Republic of Khakassia).


The release of immunoreactive growth hormone (GH) from male rat anterior pituitary explants was measured under a variety of experimental conditions. After a somewhat higher initial level, secretory rates remained essentially constant during a five-hour incubation period. Theophylline and dibutyryl cyclic AMP alone and in combination significantly stimulated GH secretion. Ammonium acetate and ammonium chloride (25 mM/L) also increased GH output by two-threefold. Unlike theophylline which increased both pituitary cyclic AMP levels and GH content of the medium, ammonium ion stimulated GH release was not accompanied by increased concentrations of intracellular cyclic AMP. Beef hypothalamic extracts, crude and purified, failed to stimulate GH release. Cerebral cortex extract and synthetic lysine vasopressin were also without effect. Epinephrine exhibited an inhibitory tendency on theophylline and cyclic AMP stimulated GH secretion. The results, which support the "second messenger" concept, are discussed in rel...

SiGe/Si n-type modulation doped field effect structures and transistors (n-MODFETs) have been fabricated on r-plane sapphire substrates. The structures were deposited using molecular beam epitaxy, and antimony dopants were incorporated via a delta doping process. Secondary ion mass spectroscopy (SIMS) indicates that the peak antimony, concentration was approximately 4 x 10(exp19) per cubic cm. The electron mobility was over 1,200 and 13,000 sq cm/V-sec at room temperature and 0.25 K, respectively. At these two temperatures, the electron carrier densities were 1.6 and 1.33 x 10(exp 12) per sq cm, thus demonstrating that carrier confinement was excellent. Shubnikov-de Haas oscillations were observed at 0.25 K, thus confirming the two-dimensional nature of the carriers. Transistors, with gate lengths varying from 1 micron to 5 microns, were fabricated using these structures and dc characterization was performed at room temperature. The saturated drain current region extended over a wide source-to-drain voltage (V(sub DS)) range, with (V(sub DS)) knee voltages of approximately 0.5 V and increased leakage starting at voltages slightly higher than 4 V.


The short-term effect of insulin-like growth factor I (IGF-I) on GTH I (FSH-like), GTH II (LH-like), and GH production by cultured rainbow trout pituitary cells was studied in immature fish of both sexes, at early gametogenesis and in spermiating and periovulatory animals. IGF-I had no effect on basal GTH I and GTH II release, whereas it always inhibited basal GH, showing decreasing intensity with the gonad maturation. In absence of IGF-I, GTH I and GTH II cells were always responsive to GnRH, whereas no response was observed for GH cells whatever the sexual stage. The action of IGF-I on the sensitivity to GnRH differs between GTH and GH cells. The former requires a coincubation with IGF−I (10−6 m)/GnRH to show an increase in sensitivity, independent of the sexual stage. To be responsive to GnRH, the GH cells require longer exposure to IGF-I, the efficiency of which decreases with gonad maturation. The action of IGF-I (10−6 m) on GTH cell sensitivity to GnRH does not seem to be related to a mitogenic effe...


Repair of UV-induced damage in the cell is crucial to maintain genome integrity and stability. Acetylation of the histone ammo-terminal tails plays key roles in transcription and DNA repair pathways. Acetylation states are determined by a balance between the activities of histone acetyltransferases (HATs) and histone deacerylases (HDACs). This study examined the roles of histone deacetylation in transcription and nucleotide excision repair (NER) in Saccharomyces cerevisiae using mutant strains defective in one or more of the genes encoding the deacetylases Rpd3, Hdal, Hosl, Hos2 and Hos3. Single mutations in the genes RPD3 and HDA1 and the various tested combinations of triple mutations did not cause any detectable loss of transcriptional repression of the model MFA2 gene. rpd3 and hdal mutants were not found to confer a significant change in sensitivity to UV radiation, however all triple mutations tested resulted in increased UV sensitivity of the cells. Examination of the removal of UV-induced cyclobutane pyrimidine dimers from the genome overall revealed that combined mutations in RPD3, HOS1 and HOS2 or in RPD3, HOS1 and HDA1 resulted in enhanced NER, which intriguingly appears to contradict the UV sensitivity effects. Enhanced NER was also observed at the repressed MFA2 gene for the same triple mutations, indicating roles for the histone deacetylase genes in chromatin alteration during both global and local NER. The NER effects were only observed upon deletion of multiple genes, suggesting a degree of functional redundancy among the deacetylase proteins. Increasing evidence for an epigenetic histone code and interplay between post-translational histone modifications led to speculation that histone phosphorylation may also play a role in NER. Increased UV sensitivity was conferred by specific mutations in the tails of histone H2A and H2B. Genome-wide analysis in a histone mutant with the H2B tail truncated at serine position 125 suggested that any roles for this site in NER are likely to be specific to certain regions of the genome rather than involved in global NER.


The molecular connectivity index combinations used to describe the physicochemical properties of the α-amino acids were specifically analyzed in terms of their statistical meaning and, especially, of their Q (quality) value. Combinations of ordinary connectivity indexes provide a good description of nearly every physicochemical property examined but especially of the isoelectric point, side-chain volume, and crystal density of the α-amino acids


During a regular survey along the Palk Bay on 25th July 2018, 16 specimens of Marivagia stellata were collected from shore-seine operations at Dhargavalasai in Ramanathapuram District of Tamil Nadu, southeast coast of India. The presence of M. stellata has been reported along the west coast earlier, however, this is the first time the occurrence of this species is reported along the Palk Bay coast of India. M. stellata is relatively a smaller jellyfish species and has been described only in 2010 from the Mediterranean coast of Israel. This species' sting is not harmful to human.


Objectives: To evaluate the presence of XIST on ring X and to correlate the pattern of ring X replication to the IQ level. Subjects: Fifteen cases with TS who had 45,X/46,X,r(X). They were subjected to I.Q. estimation, FISH using WCP for X, locus specific identifier for XIST, differential replication pattern with BrdU for r(X). Results: By FISH, it was noted that these rings were derived entirely from the X chromosome. XIST was not deleted in all cases, a very small percentage of mosaic cell line was found in three cases who had deleted XIST and also two of them had double r(X). Ten cases had small rings, 5 had large rings. MR was found in 90% of cases with small r(X) while the large r(X) had normal mentality. A significant correlation was found between the presence of small ring X and lower IQ level. The correlations between the IQ level and age at presentation, percentage of r(X) and presence of active r(X) were not reaching a significant level. Conclusion: FISH is useful in identification of hidden cell line. The mentality in TS is affected by the presence of small r(X) and the presence of functioning XIST gene on the r(X).


Objectives: Sickle cell disease (SCD) has a varied clinical and biological expression depending on the hemoglobin phenotype: SSFA 2 , SFA 2 , SAFA 2 and SC. Considering the antioxidant properties of the different haptoglobin phenotypes (Hp 1-1, Hp 2-1, Hp 2-2), it seemed relevant to know their influence on the morbidity of the different hemoglobin phenotype of SCD. Thus, the objective of this study was to identify associations between haptoglobin phenotype and morbidity of different SCD phenotypes. Methods: In a retrospective cross-sectional descriptive and analytical study, with a cohort of 170 black African carriers of hemoglobin S, in Ivory Coast, West Africa, hemoglobin and haptoglobin phenotypes were determined by electrophoretic me-thods. Results: The three major phenotypes of haptoglobin polymorphism were found in the SCD cohort: Hp 1-1 (24.1%), Hp 2-1 (56.5%), Hp 2-2 (19.4%). Vaso-occlusions were associated with haptoglobin phenotype Hp 1-1, (OR = 2.03; CI 95% = [1.06 - 3.9]; p < 0.05). Probability of worse morbidity score was 4.55 times greater for hemoglobin phenotype different from SSFA 2 (CI 95% = [1.43 - 14.44]) and the probability of having the Hp 1-1 phenotype was lower (CI 95% = [0.170 - 0.705]). Conclusions: Haptoglobin phenotype was associated to morbidity-adjusted hemoglobin phenotype. The study revealed a greater probability of a worse morbidity when the hemoglobin phenotype is homozygous. Unexpectedly, the worse morbidity is associated to


Feature analysis for classification is based on the discriminately power of features. In our previous research (1997), we presented a method for measuring the non-parametric discriminatory power of features, called relative feature importance (RFI). RFI has been shown to correctly rank features for a variety of artificial data sets. In this research, we validate RFI on natural data using a multiclass natural data set.


This project includes THE FUNCTIONAL AND STRUCTURAL EVALUATION OF THE VEHICULAR BRIDGE "QUEBRADA RONDAN", LOCATED AT THE GUAMOTE-SOCAVON ROAD - KM 7 + 000, IN GUAMOTE CANTON, CHIMBORAZO PROVINCE, AND THE ANALYSIS OF TWO ALTERNATIVES OF DESIGN " for which, several field inspections, concrete test hammer, traffic count (AADT) and various structural analyzes were conducted, which are detailed in this product.

For the functional and structural evaluation, the data of various pathologies present in the bridge were field collected, which were analyzed and weighted element by element thus obtaining the condition index of each element (ICE) and the bridge condition index (PCI), for which an adequate assessment methodology was established.

In order to understand the problems of the bridge, design analysis of elements with greater involvement was made, for which we should do the redesign of external beams and supports thereby allowing compare the results obtained with specified in construction plans. Subsequently we analyzed the constructive methods used on the bridge, from the evidence present in the structure.

Finally, in response to the current condition of the structure we propose the maintenance and structural reinforcement in it for which solutions to the various pathologies and two proposals for reinforcement the external beam is raised, which include the respective reference budget.


Enterprise Resource Planning Systems provide various core business functions in Financials, Human Resources and Logistics. Oracle and SAP, popular and successful ERP vendors worldwide, continuously improve their products. Standard Query Languages play important roles either during standard or customer developments. Because the execution of Oracle e-Business Suite and SAP Business Suite applications are still based on their relational databases, queries and reports are mainly based on SQL codes designed according to old style, but reliable and robust approaches. It is reasonable to explore how new database technologies and SQL options make changes in design methodologies consequently. This paper discusses some new features of innovative SQL development in SAP, reflecting the effectiveness of innovative options in development. It is found out that developments should designed in a proper way, when old style and new methodologies are balanced for the business functions and also for the company where the developments are introduced.


OBJECTIVE
To study the types of progenitors in dental papilla cells(DPCs) and their differentiation characteristics.

METHODS
DPCs of the mandibular first molars of four-day post-natal SD rats were isolated and cultured. The expression of osteocalcin (OCN) and dentin sialoprotein (DSP) were detected using DAB kit. E11 mandible primordias, tooth germs of the mandibular first molars of one-day post-natal SD rats, were isolated and transplanted under renal capsule respectively to observe whether they could survive and continue to develop. Then the pellets with and without dissociated enamel organ were transplanted under renal capsule for 24 days.

RESULTS
Cultured DPCs could express positive OCN and DSP. After transplantation, the mandible primordias developed into cap stage. The continuous genesis of dentin and enamel increased the size of tooth germs. DPCs pellets formed dentin-like and bone-like structures, while pellets with enamel organ formed only dentin-like tissue adjacent to the frames.

CONCLUSION
There are different progenitors residing in DPCs. The differentiation was closely related to the surrounding environment.


Several services specifically devoted to power cable users (utilities and/or industrial users) are presented. The evaluation of the state of cable connections by means of onsite data collection procedures, inspection techniques and testing, the assessment of the possibility of extending the service life of aged cables in operation, maintaining an adequate level of reliability and the end-of-life management of power cable connections are briefly illustrated.


A patient with cutaneous mycosis fungoides developed pulmonary lesions while under radiation therapy. Bronchial cytologic specimens demonstrated malignant lymphocytes, which open lung biopsy confirmed to be mycosis cells. We believe this is the first report to document pulmonary involvement of mycosis fungoides by the use of bronchial cytology.


This quantitative research - correlational cross-cut was made in the district of Huamachuco, Sanchez Carrion Province, with the purpose to determine the relationship between the level of knowledge and application of practices of biosecurity measures of nursing professionals hospital Leoncio meadow Huamachuco - 2016. The sample universe consisted of 70 nursing care professionals. Two instruments were used, the first was to measure the level of knowledge on biosafety and the second a checklist to verify the application of biosecurity measures practices of nurses. The analysis of the relationship between the study variables was performed by Chi Square test (x2). It was found that 21.4% of nurses (I) have a good level of knowledge on biosafety and 64.3% had regular knowledge level and 14.3% have a poor level of knowledge. Regarding the application of biosecurity practices the results show that 84.3% of nurses (ren) if applicable practices biosecurity measures while 15.7% do not apply. It was found that there is a statistically significant relationship between the study variables, level of knowledge and implementation of biosecurity practices.


We read with interest the article by Cumberworth et al. [1]. While the focus has obviously centred on the key finding that the "incidence of serious airway complications is at least as high as NAP4," there is another area that should be highlighted. The authors found that patients living with obesity were over-represented in the group suffering airway complications, with a case to activity ratio of 2.6 in patients with a BMI > 30. This group was also over-represented in the NAP4 study [2], where 40% of all cases had a BMI > 30. In addition, the study by Shaw et al. [3] showed minor airway events are more common in theobesepopulation. This goes against the general perception and common teaching that patients with obesity do not have difficult airways per se. As a result, we must question why this population suffer a higher proportion of both major and minor airway complications. Is it poor planning and lack of anticipation of difficult anaesthetic management? Is it assuming that these airways will be straightforward, and not having back up plans in place? Is it the physiological changes leading to more rapid oxygen desaturation causing time pressure and introducing a degree of panic? Is it a lack of adequate training in this population? These are not easy questions to answer. At the Society for Obesity and Bariatric Anaesthesia (SOBA), we are keen to ensure best education and best practice for anaesthetic management in patients living with obesity and welcome support from other interested groups in order to improve the situation.


Induced defenses may evolve in natural plant populations where heritable variation in inducibility affects plant fitness. Although this has not been documented for any plant – parasite system, genetic variation in induction has been recently reported for several plant-parasite systems. Correlations between induction and fitness in variable parasite environments suggest that inducibility may indeed be subject to selection, however, these studies focussed on phenotypic (not genetic) correlations. Our current state of knowledge suggests that induced defenses may be an example of adaptive plasticity, where defenses enhance plant fitness when parasites are present, and reduce fitness when parasites are absent. Future work that focuses on consequences of genetic variation in induction and macro-evolutionary trends in inducible versus constitutive defense will help advance our understanding of the evolutionary biology of induced plant defense.


In the mid-1960s, when evaluation had just become the focus of intense scholarly scrutiny, there seemed to be little agreement about the roles that evaluation could play in the broad educational enterprise; and there was also a lack of consensus about what evaluations should look like--about their "countenance," as it were. So a number of people made pioneering efforts of description, and these writings set the agenda for much subsequent discussion. The descriptions were not primarily naturalistic, in the sense that they described what evaluations appeared to be; they were predominately normative, in that they showed what, in the mind of each author, an evaluation ought to be. One such influential paper was "The Countenance of Educational Evaluation" (1967) by Robert Stake of the Center for Instructional Research and Curriculum Evaluation (CIRCE) at the University of Illinois at Urbana-Champaign. (CIRCE was a testing center that was converted by Thomas Hastings, Lee Cronbach, and Jack Easley into a technical assistance center for curriculum reform projects nationwide.) Stake opened by arguing that different segments of the population (what we might now call different stakeholders) expected different things from educational evaluations; and he suggested that many educators leaned toward informal evaluation:; of their programs and were skeptical about the value of formal evaluations. Turning to what formal evaluations should be like, Stake pre.sented a 3x4 matrix to classify data that could be collected. He was not suggesting that data for all of these cells had to be collected in any one evaluation, but rather he offered the matrix as a way of reminding evaluators of the possibilities that were open. However, in a time when evaluators were hungry for guidance, many grasped his ideas as a prescription--as a "countenance model." Basically, Stake distinguished a half matrix of "descriptions" from the remaining six blocks of "judgments." When describing a program, one could record antecedent intentions of the program, intended transactions (e.g., the things that were intended to be done in the classroom by the teacher delivering the program to students), and intended outcomes; and one could record observed antecedents,


This article explores the intimate historical and modern connection between manhood and nationhood: through the construction of patriotic manhood and exalted motherhood as icons of nationalist ideology; through the designation of gendered 'places' for men and women in national politics; through the domination of masculine interests and ideology in nationalist movements; through the interplay between masculine microcultures and nationalist ideology; through sexualized militarism including the construction of simultaneously over-sexed and under-sexed 'enemy' men (rapists and wimps) and promiscuous 'enemy' women (sluts and whores). Three 'puzzles' are partially solved by exposing the connection between masculinity and nationalism: why are many men so desperate to defend masculine, monoracial, and heterosexual institutional preserves, such as military organizations and academies; why do men go to war; and the 'gender gap', that is, why do men and women appear to have very different goals and agendas for the '...


To ensure that the power supply can be restored quickly when the ship's power system fails, the fault reconstruction method of the system is studied. Taking the number of switching operations and load loss as the objective function, the traditional genetic algorithm is improved by introducing a Tent population initialization, adaptive crossover probability, and mutation probability to realize the fault reconstruction of the ship regional distribution system. Two reconstruction examples show that the improved genetic algorithm can effectively solve the reconstruction problem of the ship's regional distribution power system, and has good convergence speed and accuracy, which can ensure the stable operation of the ship power system.


Phosphine fumigations of paddy rice in bagged-stacks and in bulk were undertaken at Xinzhao Panyu State Grain Depot, Guangzhou, China in 2002. Our aim was to develop and verify national standards for sheeted fumigations. Both the bulk and bagged paddy were stored protected from the weather in concrete warehouses and were sheeted on the bottom, top and four sides with clear polyvinyl chloride (PVC). Sheets were heat-sealed together and sealed to the floor by rubber tubes and plastics grooves. 7g m -3 AlP (producing 2.3 g m -3 PH 3 ) was applied to each storage by conventional application of tablets in plastics bags with a slow release technique. Twelve cages of mixed age cultures of resistant insect strains were placed into each fumigation. Insects used in the trials, included Rhyzopertha dominica, Sitophilus oryzae, Tribolium castaneum, Oryzaephilus surinamensis and Cryptolestes ferrugineus. Insects were removed from the fumigations at 14 days and 28 days. Mixed age cultures of resistant insects were completely controlled. In the bulk paddy warehouse, concentrations of phosphine remained above 375 ppm for the first 14 days. Use of conventional fumigation plus the slow release technique was successful in prolonging the period of effective concentration of phosphine sufficient to control all known resistant strains.


In our efforts to model the totality of synchronic and diachronic language behavior in complex social groups, we developed a meta-symbolic simulation system that includes a powerful behavioral simulation programming language that models, generates and manipulates events in the notation of a semantic network that changes through time, and a generalized, semantics-to-surface structure generation mechanism that can describe changes in the semantic universe in the syntax of any natural language for which a grammar is supplied. Because the system is a meta-theoretical device, it can handle generative semantic grammars formulated within a variety of theoretical frameworks.


To determine the accurate height, it should be considered geometric height difference obtained by levelling as well as the physical height difference what so called orthometric correction. The orthometric correction amount is small enough to ignore at flatland but the amount is big at high mountains, so it should be considered to obtain accurate height at high mountains. But the calculation process is difficult and complex, not easy to calculate. So, to make the process easy using a user-friendly visual, a orthometric correction calculation program Ortho-Calc. v1.0 was developed in this study. This program was adopted the algorithm of Nassar and Hwang & Hsiao, and Strang Van Hees and it could be to selectivily calculate the correction amount. The inspection result exhibited high accuracy with the standard deviation of 0.024mm by the comparison of previous study. Therefore, This program Ortho-Calc. v1.0 developed in this study, will contribute orthometric correction calculation quickly and easily. And, if this program is widely popular, it could be expected to make a contribution the Benchmark's official height renewal using orthometric correction.


We studied clinicopathologically 22 cases of primary gastric lymphoma and evaluated the factors affecting the survival rates after operation. Seventeen patients underwent curative operation and 3 patients underwent noncurative operation; the resectability was 91%. Macroscopically there were 2 cases of type 2c, 2 of Borrmann type 2, 16 of Borrmann type 3 and 2 of Borrmann type 4. Mean size of the tumors was 10.4±4.8 cm. Lymph node involvement was observed in 4 of 8 cases with ps (-) and 6 of 13 cases with ps (+). Four cases were categorized into stage 1, 3 cases stage 2, 10 cases stage 3, and 5 cases stage 4. Histologically the majority was classified as diffuse type, including 12 cases of diffuse large type and 6 of diffuse medium type. The 5-year survival rate of curative operation was 43.2%, and 0% for noncurative operation with a significant difference. Adjuvant chemotherapy using CHOP changed the survival rates, however, radiation therapy did not. Clinicopathologically the prognosis of cases in stage 1, ps (-) or growths less than 14 cm was relatively good, but lymph node involvement or histological type did not affect the survivals.


In this article, the problem of dynamic event‐triggered control (ETC) for Markovian jump linear systems (MJLSs) with time‐varying delay is investigated. First, the original system is transformed into an interconnection system with input–output form. Then, the dynamic ETC is proposed to reduce the transmission frequency. Meanwhile, the conditions of stochastic stability are proposed by constructing a novel stochastic Lyapunov–Krasovskii functional and using the scaled stochastic small‐gain theorem. Further, the controller design method is presented to stabilize the closed‐loop MJLSs with time‐varying delay. The merit of this article lies in that the conservatism for stability results is reduced and the transmission efficiency is improved by reducing the event‐triggered times, which is made possible by designing dynamic ETC. Finally, two numerical examples are provided to demonstrate the advantages and effectiveness of the proposed methods.

Abstract Background: The role of respiratory viruses (RV) in children with cancer having febrile neutropenic episodes has not been well studied. The objectives of our study were to investigate the prevalence and clinical outcomes of Respiratory viral infection (RVI). Methods: Children with cancer and febrile neutropenia (FN) having acute respiratory infections (ARI) were considered as cases and febrile neutropenic cancer patients without ARI were considered as controls. A throat swab sample was obtained for the detection of 21-respiratory pathogens. Results: A total of 81 episodes of FN in cases and 37 episodes of FN in controls were included. Prevalence of RVI (at least 1 RV) was seen in 76.5% of cases and 48.6% of controls (p = 0.005). The mixed-respiratory viruses (co-infections of ≥2 viruses) were seen only in cases (26%) (p = 0.00). Rhinovirus (36.8%) and respiratory syncytial virus (13.6%) were the most frequently detected viruses. Median duration of fever before presentation was more in cases with RVI compared to without RVI [2 (1–5) days vs 1 (1–5) day (p = 0.012)]. The median total duration of febrile period was 4 (IQR, 3–6) days in cases with RVI and 3 (IQR, 1–4) days in cases without RVI (p = 0.005). The median duration of antibiotic days were longer in cases with RVI as compared to patients without RVI [9 (IQR, 7–17) days vs 7 (IQR, 6–10) days (p = 0.046)] respectively. Conclusion: There was high prevalence of RVI in children with cancer and FN; more in association with ARI. The RVI were associated with prolonged febrile period and days of antibiotics therapy.


This paper proposes Composite Nonlinear Feedback (CNF) controller application for yaw rate tracking control of active front steering (AFS) for vehicle equipped by Steer-by-Wire (SBW). CNF controller is used in AFS system to achieve a fast tracking response of yaw rate according to the desired response and to generate correction steer angle input to enhance vehicle maneuverability. A 2-DOF linear vehicle model is used to design the controller and as the vehicle plant for the simulation evaluation. In order to analyze the proposed control strategy performance, the designed controller was simulated using J-curve and lane change maneuvers conditions and then compared with conventional Proportional Integral Derivative (PID) controller. The results show CNF has a fast yaw rate tracking capability and manage to improve vehicle maneuverability compared to conventional.


It is argued that M. Otero-Leal et al. [PRB 79, 060401 (2009) [1] wrongly identified the second order term of the Arrott equation with the coefficient at the quartic term of the Landau expansion, therefore deriving absolutely unsupported conclusions on the phase diagram of MnSi.


In January 2009, Chile will require its listed companies to adopt IFRS. Malaysia has a tradition of modifying the IFRS before adopting them. Chile's legal system is based on the French Civil Law tradition and Malaysia's legal system is based on the English common law tradition. Hence, this study investigates whether the listed firms in these two countries use deferred tax expenses to manage their earnings. It also studies the factors that affect the amount of deferred tax expenses reported. The study finds that beyond total accruals, deferred tax expenses are not incrementally useful to detect earnings management. Further, the amount recognized as deferred tax expenses is significantly associated with changes in operating cash flows, and in Chile, it is also related to the level of institutional ownership in listed firms.


The invention relates to a display device and a display control method thereof. The display device includes a first display unit which is configured to include a plurality of first sub display units, wherein each first sub display unit has a first sub state used for reflecting light of a specific wavelength and a second sub state used for transmitting light; a second display unit which is arranged below the first display unit; and a display control unit used for controlling the first display unit and/or the second display unit to execute display, wherein the display device includes first and second work states. When the display device is at the first work state, the display device controls part of the plurality of first sub display units of the first display unit to be at the first sub state so as to execute display and the remaining parts of the plurality of first sub display unit to be at the second sub state; and when the display device is at the second work state, the display device controls the plurality of first sub display units of the first display unit to be at the second sub state and controls the second display unit to execute display.

Viral load is proving to be a stronger predictor of HIV disease progression than CD4 counts, and viral load testing is expected to supercede CD4 tests as a means to guide treatment and gauge the effectiveness of new drugs. Physicians and patients are using viral load testing to make more informed treatment decisions. Data suggests that treatment should be initiated when viral load is 10,000 copies, regardless of CD4 count. Viral load testing is also seen as a reliable marker for predicting the risk of opportunistic infections and for determining the timing for preventive treatment for these infections. Researchers' recommendations and research methods are reviewed.


A new method based on Ensemble Empirical Mode Decomposition( EEMD) was proposed aiming at extracting the non-stationary characteristic of the acoustic emission( AE) signal from pipeline leakage to improve the precision of location. The detected leakage signal can be denoised by wavelet and decomposed into several intrinsic mode functions( IMF) by EEMD. The IMFs having real physical meaning were reconstructed to determine the time difference and leak point by cross-correlation method. Simulation and experiments indicate that the method presented above can eliminate the disadvantages of direct crosscorrelation and Empirical Mode Decomposition( EMD) method,which improves the precision of location.

A half century ago, 70 cancer professionals gathered in a conference room in Philadelphia in what would mark the first scientific meeting of the American Society of Clinical Oncology (ASCO). At the time, it would have been impossible to predict the achievements in cancer prevention, care, and treatment that have been made in the United States and other developed countries, resulting in significant improvements in survival from cancer and quality of life. Many of the advances have been cataloged in this journal, now widely read as the predominant oncology publication. Much of the world's burden of cancermortality occurs not in the developed world, but in the developing world, and in this Special Series of Journal of Clinical Oncology (JCO), the editorial board has granted us the opportunity to focus on the ever-increasing burden of cancer in parts of the world often thought to be plagued only with infectious diseases, or so-called diseases of poverty. What is less well documented, and certainly less frequently at the nucleus of scientific dialogue, is the diversity of cancer biology around the world and the diversity of how countries and partners are responding to the major global burden of cancer. Globally, in 2013, an estimated 15million patientswere newly diagnosed with cancer, and 8.2 million people died. That year alone, almost half amillionwomendiedof breast cancer, a disease that, if caught in early stages, wenowunderstand to be largely treatable andoften curable. Today in theUnited States, despite a consistently high incidence rate, a cancer diagnosis is most often accompanied by a set of therapeutic plans to prolong life or even cure the patient, and approximately 70%of patients with cancer can expect to live for more than 5 years. Sowhere are the 8.2million people dying each year?Many deaths still do occur among patients in developed countries, but two thirds of cancer deaths occur in the developing world. Doubly encumbered by a sparse and overtaxed health care workforce and a high burden of both communicable and noncommunicable diseases, countries in the developing world face extreme barriers to addressing the needs of patients with cancer. Not only are cancer facilities few and far between in low-income countries, but even where they do exist, they are often unaffordable for much of the population. However, as one of our authors, Paul Farmer, has reminded us in many conversations, "We live in one world, not three." The vast expanse of knowledge, tools, and clinical advances inwealthier countries can have a tremendous impact if applied in partnership with countries currently struggling to establish ormaintain nascent cancer research, prevention, and treatment programs. In this vein, we have solicited articles from authors around the world who are engaged in global cancer care and control across a number of scientific disciplines, including biology, public health, medical education, policy, and delivery science. It is our aim through this Special Series that the cancer community continues to expand its purview to all those in need of cancer care, no matter where a patient happens to live. The series opens with an article on the imperatives of bringing cancer care to the poor, weaving in the history of the HIV treatment access movement two decades ago. Barriers to high-quality cancer care and the resultant poor patient outcomes were examined in low-, middle-, and high-income countries exploring commonalities (the effects of poverty, for instance), and differences in these settings, using Kenya, Brazil, and the United States as examples. Structural barriers to early detection and timely treatment were explored in depth by Cazap et al. The spectrum of services required for cancer care is long, and two articles on pathology and radiation therapy illuminate challenges and practical solutions specific to these points along the care delivery chain in low-income countries. Developing andmaintaining strong cancer care infrastructures require human resource capacity to run, manage, and optimize them. Authors working in Kenya's rural west describe a medical education and training partnership for cancer care. Delivering cancer care in resource-constrained settings provides a multitude of unique challenges and often nonconventional and innovative approaches. Continuous evaluation of results with identification of gaps, together with targeted interventions to improve the safety and efficacy of care, requires data collection and reporting, and a partnership in Rwanda calls for the integration of implementation science into global cancer medicine. Global pediatric oncology is an area that receives much less attention than it should. Although cancer in childhood is less common than in adults, the potential cure rates are high, and those cured have a long and productive life that will be tragically lost if access to quality cancer care is not available. The series editors asked some of the world's leading experts to describe their experience of partnership to respond to the needs of children with cancer around the world. Another oft-overlooked area of international cancer control is pain management. Given the late-stage presentation of disease in many low-income countries, authors describe the need for palliative and supportive care. Although some improvements in access to essential cancer medicines have beenmade in recent years, many in the world have little or no access to affordable cancer medicines. Shulman et al share methodologies and outcomes of a collaboration with WHO, which has increased the number of cancer medicines on their Essential Medicines List. ASCO has played an important role in global cancer medicine over many years and more so recently. Chronicling the


ABSTRACT Madeleine Rebérioux was right to wonder whether France was truly a 'Radical republic' in the years between the Dreyfus affair and the Great War. Archives only opened or explored since Rebérioux published in 1975, and the re-interpretation of older newspaper sources, show that control of the Third Republic was still hotly contested in those years. The Radicals tried to build a republic in their own image, but in a situation where left and right were closely balanced, they were almost always foiled. Crucial to this process was a politically republican but socially conservative centre – best typified by the A.R.D. The A.R.D. wanted a Third Republic frankly favourable to the interests of big business. Since it held the parliamentary balance of power between the left and a right only partly republican, it generally got its way. Statistical sources also support this interpretation.


: Forging work is to form metal to produce a final product by providing a compressive force at a certainty loading speed. Forging at high heat will soften the material when struck with a hammer or by compressive forces. One of the forging products is a work knife in the kitchen. Production usually has corrosion resistance and wear resistance. In addition to stainless steel, knives it also made of carbon steel, leaf plate spring steel, and other heavy equipment steel waste. Manufacture of blades by engineering the addition of metal to parts with hardened welding technology. The selection of electrodes considers quality by choosing electrodes with alloy steel compositions such as Manganese (Mn), Chromium (Cr), Silicon (Si). Hard-facing data on two types of hard-facing material and leaf plate spring steel showed an increase in the hardness of these materials. Analysis of variance shows the effect of material factors and hardening factors by quenching on the hardness of the test material. In addition to hardness, the analysis results show the material's resistance to rust. The influence of the chemical composition of the alloy steel, namely chromium, causes corrosion resistance of the test material. Another interesting fact thing is the use of control variables in testing between variables. The variable used is a knife to analyze descriptively under binocular microscope observation.


We present a new approach to deriving necessary conditions for stochastic partially observed control problems when the control enters the drift coefficient, and correlation between signal and observation noise is allowed. The problem is formulated as one of complete information but, instead of considering the unnormalized conditional density of nonlinear filtering, using Kunita's decomposition this equation is decomposed into two measure-valued processes. The minimum principle and the stochastic partial differential equation satisfied by the adjoint process, are then derived, and are shown to be the exact necessary conditions when the correlation is zero.<<ETX>>

The zipper cord attachment includes a male element and a female element. The male element includes cord channels for engaging and securing the ends of a zipper cord or similar cord. The male element includes a guide ridge complementary to a guide slot within the female element. The female element includes ramped surfaces proximate to an end of the guide slot to detent engage a transverse wall of the male element. After installation, pulling on the cord urges the male element more tightly into the female element. That is, pulling on the cord tightens the grip on the ends of the cord by points or striations formed on the male element and supports formed on the female element.


The findings of a Government-commissioned study into the feasibility of road pricing in the UK are summarized. The study showed that a nationwide scheme cold not be introduced until at least 2014. The introduction of local charging schemes was recommended, with some form of consistency to ensure interoperability in the future. The relationship between the Secretary of State and local schemes would need to be a key focus of any future legislation that sought to formalise partnerships between central and local government in developing charging schemes. Government help with the implementation of local congestion charging schemes in advance of a national road pricing system was recommended. Models were used to investigate the possible outcomes of various road pricing schemes based on wholly or partially replacing fuel duty.


Abstract Ensuring descriptive representation of racial minorities without packing minorities too heavily into districts is a perpetual difficulty, especially in states lacking voter file race data. One advance since the 2010 redistricting cycle is the advent of Bayesian Improved Surname Geocoding (BISG), which greatly improves upon previous ecological inference methods in identifying voter race. In this article, we test the viability of employing BISG to redistricting under two posterior allocation methods for race assignment: plurality versus probabilistic. We validate these methods through 10,000 redistricting simulations of North Carolina and Georgia's congressional districts and compare BISG estimates to actual voter file racial data. We find that probabilistic summing of the BISG posteriors significantly reduces error rates at the precinct and district level relative to plurality racial assignment, and therefore should be the preferred method when using BISG for redistricting. Our results suggest that BISG can aid in the construction of majority-minority districts during the redistricting process.


Charge trapping is dramatically suppressed in ZnO transparent thin film transistors (TFTs) employing a multilayered gate insulator with HfO2 layer sandwiched by Al2O3 layers. In spite of its high dielectric constant, HfO2 has critical drawbacks including huge charge trap density in interfaces. We suggest and demonstrate an elegant solution to minimize the charge trapping introducing Al2O3 buffer layers. The operation of Al2O3∕HfO2∕Al2O3 multilayered gate-insulator structure in the ZnO transparent TFT is evaluated to ensure the voltage difference in the hysteresis loop as low as 0.2V, and the immunization to the threshold voltage shift induced by repeated sweeps of gate voltage.


In virtue the polytopic system theory, the present study proposes a wide-area robust decentralized coordinated controller that stabilizes the system and enhances the system robustness simultaneously under different operating conditions. Based on the design algorithm, the closed-loop control system can be operated under strong damping mode in virtue of the stability criterion based on damping ratio. A wide-area robust decentralized coordinated control framework for HVDC power system is then put forward, where the upper level wide-area coordinated controller is designed as a dynamic output feedback controller that coordinates the lower level HVDC supplementary controller, PSS and SVC. Simulation results have demonstrated the effectiveness and applicability of the proposed controller.


Mice of C57BL/6 strain were singly injected intraperitoneally with antibodies (AB) to serotonin (5-HT). The "open-field" testing in different periods after the AB injection revealed a depression of behavior within 1.5 h which changed for activation within 1 day and, again, depression within 5 days after the injection. The analysis of neurotransmitter content in the sensorimotor cortex and hypothalamus revealed increased levels of serotonin and, especially, dopamine in the cortex within 1 day. The cortex serotonin level within 5 days was also increased. The possible mechanisms are discussed of neurotropic action of AB to 5-HT.


Agoraphobia and Loss of Social Self-Respect .
In this article, a new theory is presented about agoraphobia (the fear of public places). The term public places refers to the locations where public life takes place. Public life takes place amidst "the people", "the public", in other words amidst people in their role as members of society. It is argued that the playing of this role presumes a certain awareness of social status, a certain social self-respect, on the part of the persons involved. Agoraphobia is thought to be due to the loss of this social self-respect resulting from the elimination of the roles and positions it was based on. This kind of loss makes inter action with other members of society impossible, so that one is no longer able to move freely among them. The avoidance of public places can also mean that an
individual has never had this kind of self-respect. Characteristic features of agoraphobic behaviour are proached from this angle. Agoraphobic anxiety-reducers, for example, can thus be viewed as status symbols that the persons involved can utilize to provide themselves with a social identity. Analysis has shown that the situations agoraphobic persons are most sensitive to are particularly apt to present a threat to their status. Lastly, a link is drawn between this theory and the relatively low social status of the groups where agoraphobia is most frequent or where the symptoms are most serious.


Marine predators recovering from historic, commercial, over-harvesting can create conservation challenges when they prey on vulnerable species. Pinniped predation of seabirds presents one such challenge and identifying the source colonies experiencing seal predation are needed to inform conservation management and decision planning. Here, we present a novel application of stable isotope and trace element techniques to identify the source colony of little penguins (Eudyptula minor) predated by long-nosed fur seals (Arctocephalus forsteri). We created baseline biochemical 'feather-prints' from feathers for six major breeding colonies across south-east Australia to compare with feathers from predated penguins recovered from seal scats. Feeding trials of captive seals confirmed that digestion of penguin feathers did not compromise stable isotope (δ13C and δ15N) or trace element (Al, Ti, Sr and Mg) signatures. The resulting biochemical 'feather-prints' were found to be robust in being correctly classified to local sites (78%) and broader regions (85%). The distinguishing 'feather-prints' appeared to be driven by industrial inputs from land, colony-specific foraging patterns and potentially proximity to oceanographic systems (i.e. upwelling). Here, we show that 46-70% of predated feathers were assigned to 'local' penguin colonies. We consider that the regional penguin abundances and the proximity of their colonies to seal sites, as well as demographic-specific foraging patterns may shape their contribution to seal diet at local, regional and inter-regional scales. This diagnostic tool is powerful, having broad applications identifying seabird colonies at greatest risk to pinniped predation and informing targeted, site-specific, conservation effort.


Cellular structures are similarly identified as lattice structures or foam structures which are commonly constructed of ligaments. Cellular structures exist widely in nature, such as the coral, honeycomb, and the natural bones. Cellular structures are also manufactured and used in various applications such as honeycomb bumper structures and truss bridge. Ti6Al4V is one of the most commonly used titanium alloy and is applied in a wide range of application where low density very good corrosion resistance are necessary such as direct manufacturing of part and prototypes for racing and aerospace industry, biomechanical application such as implants and prosthesis, marine application, chemical industry, and gas turbine. This paper investigates the mechanical properties of Ti6Al4V lattice structures fabricated by additive manufacturing, also known as 3D printing. The samples are fabricated by selective laser melting (SLM) using titanium alloy (TI6Al4V). Four factors were selected to determine its influence on the Young's modulus and compressive strength, which is strut size, strut shape, unit cell size, and porosity. All the samples categorize to six groups by its design volume porosity obtained from CAD file. Solidwork design software was used in this study. The influence was shown in a comparison graph. Detailed characterizations of compression test were conducted and reported. The built structures have a Young's modulus ranging between 0.01 and 1.84 Gpa. Porosity was realized to play an important role in determining the Young's modulus and compressive strength.


Financial security of a country is an integral part of its economic security and the basis of national security. The paper aims to assess and forecast the level of Ukraine's financial security using two methodological approaches (the existing one and the authors' elaboration) to choose the best alternative. The first one is based on the Methodology of the Ministry of Economy of Ukraine. The alternative one has been developed as a multiplicative model of non-linear convolution of relevant direct and indirect impact indicators, considering the opportunity and risk, which is based on a combination of a power function and the Harrington method. A database of input indicators was formed with further differentiation according to their impact on Ukraine's financial security. The research results demonstrated that during 2013–2019 Ukraine's financial security integrated index was cyclical and constantly changing. A comparison of the existing methodology and the developed model demonstrated a certain discrepancy between the obtained results. It was substantiated that the proposed multiplicative non-linear convolution model for assessing and forecasting the state's financial security is more relevant, includes current indicators sorted by their direct and indirect impact, and adjusts them according to the risk of impact on overall security in the country. financial independence, external and domestic debt, the nature of financial and credit policy, political climate, the level of resource provision of the healthcare system, culture, education, and science. In this context, the role and importance of the financial system have changed dramatically in recent years. From being the usual mechanism for servicing economic processes, finance has become the basis of modern economic development and society, whose role in the growing globalization of the world economic relations is only increas-ing. The financial system must have a certain margin of safety in the event of unforeseen and extraordinary circumstances, in particular, to enable public authorities and other economic operators to respond in a timely manner to any threats and to prevent, neutralize, or at least

PURPOSE
This study aims to develop and evaluate the effectiveness of full 3-dimensional motion platform in respiratory-gated radiotherapy (RGRT) quality assurance (QA). For this study, a motion platform had been developed to simulate the patient specific QA in RGRT. Commercial motion platforms have the limited freedom of movement : lateral-longitudinal or vertical movement for tumor motion, and vertical movement for the external marker motion. Addition to these, the developed platform has the freedom of full 3-dimensional movement: simultaneous lateral, longitudinal as well as vertical motion for tumor motion.

METHODS
3-dimensional tumor motions of ten abdomen cancer patients treated RGRT with no-motion, 2-dimensional 0motion, and 3-dimensional motion were extracted in phase sorted 4D-CT images. After deformable registration based on contoured image in 50% respiratory phase, the center of voxel was defined as the tumor position to trace its motion. Varian RPM log files were used to trace external markers. 3-dimensional tumor motions were simulated using the developed motion platform. On its polycarbonate panel, a radio-chromic film attached on 10 cm solid water slabs was placed for the dose verification. 2-dimensional and 3-dimensional tumor motions were performed with gated beam delivery to compare their dosimetric differences. The gating window was 35-65%. Gamma-index method was adopted to compare dose distributions of the measurement using radio-chromic film with those of treatment planning system.

RESULTS
The average gamma pass rates (2%/2 mm) were 96.11%, 89.69%, and 88.86% for static-continuous, 2D-gated, and 3D-gated, respectively. Excepting one case, static-continuous showed results over 94%. Some of 3D-gated resulted in pass rates larger than those of 2D-gated.

CONCLUSION
3-dimensional tumor motions showed lower gamma pass rates than those of 2-dimensional tumor motions during treatment. These imply the requirement of tools that provide the 3-dimensional tumor motion for QA in RGRT.


A frequency-tunable compact antenna based on quarter-mode substrate integrated waveguide (QMSIW) technology to reduce the size of the antenna is proposed. The resonant frequency of the antenna is electronically controlled by a dc bias voltage of a varactor loaded between the QMSIW and an additional parasitic patch on the top plane of the structure, with the bias network designed on the bottom plane. The performance of this antenna is demonstrated experimentally, with its resonant frequency varying from 2.28 to 2.50 GHz by increasing the dc bias voltage from 0 to 30 V.


Introduction Patients with advanced liver disease live mainly in the community with treatment of complications provided for in-hospital. The illness trajectory of advanced liver disease is uncertain and most do not have access to end of life care. Gaps in knowledge and understanding of the patient experience of this condition have been identified. Methods Secondary analysis of 15 transcripts from in-depth interviews with people with advanced liver disease collected as part of a previous longitudinal study on the experience of liver disease. Transcripts were thematically analysed for emotional content. Results Fear, anger, sadness and guilt clearly featured in the person's experience of advanced liver disease. Certain causal factors were identified as provoking these emotional responses, including shock of diagnosis, uncertainty concerning illness, lack of coordinated care, worrying symptoms and sudden death. Humour emerged as a coping mechanism. Conclusion People living with advanced liver disease experience distressing emotions. It is helpful for clinicians, nurses and other healthcare support staff to have an appreciation of the person's emotional concerns in order to provide holistic care typical of a palliative approach.


This paper introduces a model-based robust adaptive input-output control framework for a family of robotic systems that include under-actuation, nonholonomic, and constrained properties. The proposed control framework can provide fast and effective controller generation for modular robotic systems (MRS) with interchangeable subsystems. The controller was first derived based on the general properties of nonholonomic robotic dynamic models while considering under-actuation and constraints. Then the adaptive control technique is introduced to overcome the effects such as inertia and force uncertainties. Robust augmentation is implemented via inverse optimality theory, which is verified with respect to a meaningful cost function. A simulation study on an aerial manipulator system with model uncertainty and disturbance was provided to demonstrate the characteristics and effectiveness of the proposed controller.


Figures are given for the yield, specific gravity and composition of samples of milk collected at varying intervals throughout lactation from eight Cheviotewes kept under experimental conditions and of odd samples taken from ewesunder natural grazing conditions in different parts of Scotland. The figures recorded do not show any marked differences in compositionas a result of wide differences in the calcium content of the rations.


An analysis of the issues relating to the mash-up genre and adaptation with specific reference to Austen's Pride and Prejudice.


The High Fidelity Generalized Method of Cells (HFGMC) has been implemented into Abaqus/Explicit in order to model damage processes in composite materials at the micromechanical level. The HFGMC model is implemented into the finite element code Abaqus via user material subroutine VUMAT. The result of the micromechanical procedure is the computation of strain concentration tensors, which relate the strain tensor on the macrolevel to the strain tensor of each subcell. This enables calculation of the stress field within the unit cell, based on the constitutive behavior of each subcell. As the stress distribution is determined for the representative unit cells, calculation of failure criteria and constitutive response of the composite are performed on the micro-level. The most frequently used micromechanical failure criteria have been used in this work as well. Parametric analyses using different unit cell shapes and discretization refinement have been performed. Results of micromechanical analyses confirm significant dependence of failure criteria on unit cell type and refinement.

ABSTRACT The combinatorial bio/chemical investigation of sediments (six surface samples and one core sample) from Osaka Bay, Japan was conducted to clarify the horizontal and vertical distribution profiles of persistent organic pollutants in the sediments. Concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs), and polybrominated diphenylethers (PBDEs) were determined by chemical analysis and compared to bioassay results using H4IIE-luc/Dioxin Responsive-Chemical Activated LUciferase eXpression (DR-CALUX). For surface sediments, World Health Organization-toxicity equivalent (WHO-TEQ) values ranged from 1.8 to 92 pg g-1 dry weight and the bioassay-TEQ (CALUX-TEQ) values (3.7 – 140 pg g-1 dry weight) yielded significant correlation with them (r 2 = 0.96). On the other hand, correlation between both TEQs (for WHO-TEQ, 5.5 – 47 and for CALUX-TEQ, 27 – 76 pg g-1 dry weight) for core samples was not so good (r 2 = 0.46). Comparing the vertical profiles of CALUX-TEQ and WHO-TEQ, they were different in that WHO-TEQ reached the maximum in the 1957 core section, while CALUX-TEQ reached in the 1984 core section. CALUX-TEQ values were 1-5-fold more than WHO-TEQ values in all the surface and core samples. CALUX-TEQ values were calculated for PBDE and PBDD/F concentrations, employing their CALUX toxicity equivalent factors (CALUX-TEFs). The estimated CALUX-TEQ values obtained for the brominated compounds could explain for 11% on average (range 4.7 – 31%) of the experimentally obtained CALUX-TEQ values in the investigated surface sediments.


The synthesis is based on Cushman multicomponent reaction, wherein aryl glyoxals are used as the carbonyl component for the first time.


Smoking is the single largest cause of
 premature mortality in the developed world. Obtaining
 accurate estimates of smoking's impacts in south east
 Europe (SEE) is hindered by the lack of accurate data.. None
 of the countries of the region yet conduct regular national
 surveys of adult smoking prevalence and some have no recent
 nationally representative data available. The very high
 rates among medical personnel are cause for concern. Youth
 smoking surveys are now conducted in most countries as part
 of international projects and show rates broadly similar to
 the EU. The collapse of communism and the end of the
 conflicts in the 1990s has led to major changes in the
 region's tobacco industry. The previously state-owned
 tobacco monopolies have either undergone or are undergoing
 privatization and the transnational tobacco companies have
 been increasingly active both in importing their cigarettes
 to, and investing in, the region. These changes can be
 expected to increase competition in the tobacco industry
 which will in turn drive down prices and increase
 advertising, thereby stimulating consumption. The available
 statistics, combined with the changes to the region's
 tobacco industry, suggest that the health impacts of tobacco
 in SEE will continue to worsen over coming years.


We evaluated the performance of anti‐Müllerian hormone (AMH) measured by the Beckman Coulter fully automated Access assay to predict oocyte yield following controlled ovarian stimulation (COS) for in vitro fertilization (IVF).


Abstract The inorganic ring systems BNCO2Si2 (B) and BCO3Si4 (E) were prepared for the first time via equations (1) and (5), system BCO3Si2 (C) enlarged by preparation of compound C 1 via eq. (4).

Compound VTI, C5H15NOSi, was obtained for the first time via eq. (7) and described in its properties.


DEEP crises in the life of a nation sometimes lay bare with lightning clarity those basic social ties, loyalties, and commitments which render possible some maintenance of order and control when everything seems about to break down or disappear. In 1945, year of the deepest crisis that the German people have undergone in modern times, groups and organizations like the Junkers or the Nazi Party simply vanished; others, like the military, disappeared at least temporarily or, like the industrialists, were gravely weakened. It was the bureaucracy which became the bedrock, the irreducible minimum of social cohesion upon which, first locally, then in larger units, society was rebuilt. Subsequently, confirmed in its traditional position of control by the occupation powers (certain measures of attempted political purge and technical reorganization notwithstanding), its actual power was enhanced by the innumerable tasks of postwar reconstruction, from the building-up of entire new administrations (in the new Länder as well as on the bi-zonal and then federal levels of government) to the handling of what has been aptly called the "universe of claims" arising out of Nazi, war, and postwar conditions.


This unique volume, comprising Colm Toibin's acclaimed short text and a linked collection of key documents put together by one of Ireland's leading younger historians, offers a many-sided view of one's of history's most poignant and far-reaching catastrophes. This book will allow the reader to understand the complex way in which the fragmentary past is both available to us...and distant from us. We get those insights from Toibin's short history and from a rich collection of documents - government papers, recipes, journalism, letters, statistics, personal statements, all linked so the book can be read as a whole.


This paper presents a hybrid approach for building a binary classifier. The approach is the combination of the k-nearest neighbor algorithm, handling separately m 1-dimensional data sets divided from a data set in m-dimension, and the logistic regression method. This hybrid KNN-LR classifier improves the performance of the logistic regression in classification accuracy in some situations where the predictor and target variables exhibit complex nonlinear relationships. The results of the experiment on four benchmark data sets show the proposed approach compares favorably with the well-known classification algorithms such as C4.5 and RBF. Furthermore, its effectiveness is illustrated by its application in customer churn prediction based on real-world customer data sets.


In the present study, we manufactured rice miso supplementary with black soybean, buckwheat and adzuki bean. We analyzed DPPH radical scavenging activity, melanoidin, peptide, reducing sugar content, and lipase inhibitory activity in various rice miso products at different fermentation periods (3, 6, 24, 36 months), respectively. DPPH radical scavenging activity, melanoidin content and lipase inhibitory activity in various rice miso products increased with prolonging the fermentation period. We found positive relationships between melanoidin content and DPPH radical scavenging activity, and lipase inhibitory activity. The correlation coefficients were more than 0.75, respectively. Rice miso supplementary with black soybean (RM-BS), rice miso supplementary with buckwheat (RM-BW) and rice miso supplementary with adzuki bean (RM-AB) exhibited significant higher DPPH radical scavenging activity, melanoidin and lipase inhibitory activity than RM (rice miso; control), respectively. We considered that due to prolonging the fermentation period, more and more starch and protein contained in RM-BS, RM-BW and RM-AB were decomposed into reducing sugar, peptide and amino acid, than those of RM. So thus rice miso supplementary with black soybean, buckwheat and adzuki bean could improve DPPH radical scavenging activity and lipase inhibitory activity of traditional rice miso products, which may be because of plenty of melanoidin was produced through the amino acid-glucose reactions. These results would utilize in the research on development functionality of rice miso products.


A well-established fact of continental stretching is that during the extension phase the lithosphere retains a finite (flexural) strength. Vertical loads caused by the redistribution of material with crustal and mantle densities during lithospheric thinning can therefore be supported by the lithosphere. Whether these loads cause flexural uplift or subsidence depends on the strength distribution within the continental lithosphere. In kinematic model studies, stratigraphic and other data acquired in the vicinity of sedimentary basins and passive margins are "inverted" for these loads. In these models, vertical rebound loads are parameterized in terms of a "necking depth" parameter. We use thermal-mechanical finite element simulations to investigate whether rheological information about the continental lithosphere can be extracted from the necking depth parameter derived from kinematic models. We conclude that spatial and temporal variations in necking depths near basin edges and passive margins as derived from our dynamic simulations are not consistent with the uniform and stationary necking depth that is usually assumed in kinematic models. This is very important since, typically, the stratigraphic data used in kinematic model studies are acquired in these regions. We therefore conclude that there is no one-to-one relation between the necking depth parameter and the strength distribution in the lithosphere.


Abstract : We have studied the magnetic and structural properties of epitaxial bcc Fe(001) films grown at 175 C on molecular-beam epitaxy-prepared GaAs(001)-2*4 and -c(4*4) reconstructed surfaces, with film thicknesses ranging up to ~30 ML (~43 ). We present measurements of the thickness-dependent evolution of the magnetic properties of the Fe films as determined by in situ magneto-optic Kerr effect. We find that the magnetic properties and growth mode are similar for both 234 and c(434) reconstructions, although the initial adsorption sites and island nucleation as measured by scanning tunneling microscopy are clearly dominated by the substrate surface reconstruction. The onset of room-temperature ferromagnetism occurs at 6 ML for growth on both GaAs surface reconstructions. At this coverage, the measured Curie temperature (100 C) is significantly reduced from that of bulk alpha-Fe (770 C). The anisotropy is dominated by a uniaxial component such that the two (110) axes are inequivalent for all coverages studied. Shape anisotropy does not appear to play a significant role.


Radical azidations and carboazidations have been achieved using 3-pyridinesulfonyl azide as azidating agent. Due to its base properties and its polarity, the excess of reagent is readily removed at the end of the reaction by filtration through silica gel or by extraction with either aqueous 1 M HCl or 1 M CuSO4. The use of this reagent greatly facilitates the tedious purifications of the final azides frequently encountered when reactions are run according to the original procedure involving benzenesulfonyl azide.


V. In studying the text of Luke, the first question at,every point must be what relation exists hetween his narrative and that of Mark, which was employed by him and to a large extent incorporated in his Gospel. Yet Luke rarely contents himself with merely transcribing Mark. Apart from stylistic improvements, which may be disregarded as adding nothing to the meaning, he often works into passages taken from l2ark new statements, which are best explained as obtained from a different authority :1 1 I in such places he took lIark's narrative as his basis, and treated other narratives, oral or written, as subsidiary. In other places he took a different


Housing inequalities accumulate over the life course and take on their greatest force in old age. Among the 95 per cent of older people who continue to live in the community, there is a polarisation between the majority of outright home owners and the minority of permanent private tenants. This article identifies the effect of housing tenure and related public policies on standards of living in retirement. Most importantly, it, concludes that increases of Supplementary Assistance are an immediate priority. A major restructuring of taxation, pension, and housing policy is recommended to resolve the more fundamental problems.


To the Editors:

We read with interest the important article by Jais et al . [1] in a recent issue of the European Respiratory Journal discussing management and outcome of pregnancy in pulmonary hypertension patients in the light of recent advanced therapy. We certainly agree that this issue should be revisited in the current era when many new potent medications are available. Yet, even in the current era with optimal management, this condition carries substantial risks and demands careful examination of the data …

The article presents the most innovative methods of strengthening and (or) seismic strengthening of masonry for use in historical buildings that are of architectural value, for example, in old mosques in Syria, which are architectural monuments. These methods are designed to protect such buildings, many of which are of architectural and cultural value and are on the UNESCO World Heritage List, from cracks of various sizes and directions and from the negative effects of earthquakes that can occur at any time. Carbon fiber reinforced polymer rods (CFRP) rods and stainless steel helical rods are considered. Two mosques in Syria are briefly described as examples of historical masonry buildings, which are architectural monuments and objects of cultural heritage. In the end conclusions are drawn.


In this paper, a kind of Linear Synchronous Motor (LSM) with Permanent Magnet (PM) arranged in Halbach array and IronLess Coil (PMH&ILC) is presented for Magnetic Levitation Vehicles (Maglev). First, the propulsion force of this kind of LSM is deduced analytically. Then, the influences of pole spacing, the current in the coil, the width of the motor and the size of the Halbach array on the propulsion force are analyzed mathematically in detail. Based on the results, the design method and basic principle of PMH&ILC-typed LSM are proposed, which shows a better performance with small pole spacing, higher permanent magnet array, optimal value of the width of the permanent magnet Halbach and so on. Finally, a sample LSM system is designed according to the requirements of Maglev propulsion system.


Internal corrosion of natural gas pipelines is a major cause of many related accidents. In addition to the metal loss due to corrosion, hydrogen ions produced during corrosion can lead to the degradation of ductility of metals used in these pipelines. The effect of hydrogen generated through internal corrosion on current pipeline steels was studied. Three grades of API 5L steels commonly used in natural gas infrastructure were investigated: X56, X65, and X100. The rates of hydrogen diffusion were determined electrolytically via a Devanathan-Stachurski cell. The steels were subjected to hydrogen embrittlement tests using electrolytic hydrogen charging and constant strain rate tensile tests. The microstructure analysis of the investigated materials and the fracture surfaces was performed via scanning electron microscopy (SEM). This presentation reports on work to extend the life of the natural gas pipeline network via understanding the mechanisms of hydrogen ingress and subsequent embrittlement induced by corrosion processes.
