starboard it has of course to be green). Immediately before steering towards the chosen direction, the long light signals will be transformed into short signals, and be entirely switched off as soon as the vessel is on its new course. Whether this signal, which dates from wartime, can be used in the open sea is another question. How-ever, I recommend the use when going into a harbour. The subject of most debates on manoeuvre signals is a 'trafficator'-signal, which signals a change of the course by night. The possibilities of this kind of signal are generally known, as periodicals are discussing the subject. At present, opinions differ on how this signalling device should be constructed. The two most frequently planned conceptions seem to be an illumintated arrow and some kind of flashing lights. The illuminated arrow has been appreciated in the Netherlands. It is the only 'trafficator'-signal which has been tested in practical use, but it has been reported that it suffers from various disadvantages.


The article describes the process of modeling and creating a compact portable foam generator of medium multiplicity with geometric and dimensional parameters that allow for the use of air-mechanical foam directly during reconnaissance without complicating circumstances that arise during reconnaissance with a gas and smoke protection service when it is necessary to supply air-mechanical foam without a foam generator, which is not included in the minimum necessary list of firefighting tools and devices.
Generally, the use of foam generators by the gas and smoke protection service during fires is a common practice and constitutes typical actions in case of fire incidents. However, there is one particular aspect in the use of generators - their weight and geometric dimensions, which may restrict the movement of personnel in relatively confined spaces such as cable tunnels, basements, and underground structures. Therefore, greater attention should be paid to the use of foam generators with medium multiplicity.
The foam isolates the combustion zone from flammable vapors and gases, as well as the combustible surface of the material from the heat emitted by the reaction zone. It penetrates well into the premises, overcomes turns and climbs, quickly fills the volume of the room, displaces combustion products heated to high temperatures, thereby reducing the temperature in the room. To ensure instant response to the situation during reconnaissance with a gas and smoke protection service, equipment should be provided that allows for confident response to complex tactical tasks for the fire suppression commander, making informed and decisive decisions regarding reducing the likelihood of emergency situations and reducing the percentage of human and material losses.
The motto of a rescuer is "prevent, save, help." This article describes a useful model that reduces the decision-making time for the fire suppression commander at the end of reconnaissance, the time of initiating the first fire extinguishing nozzle, the time of fire localization and extinguishment, which increases the likelihood of saving human lives from fire hazards.
Keywords: compact medium expansion foam generator, air-mechanical foam, gas and smoke protection service.

In order to further identify the isolated mycoplasma genilium (Mg) from the high risk population of STD in China,the technique of atomic force microscopy (AFM) was applied to observe the morphology of Mg standard strains and clinical isolates.Under normal atmospheric temperature the sample of Mg was fixed on mica and AFM images of scanning observation were captured by tapping mode.The results showed that Mg may appear various shapes,including flask pear splindle or round shape with projecting neck portion and slightly broadened the turminal structure under AFM,which are similar to those observed by EM.The size measurement of Mg pathogen from EM and AFM was similar as well.


Local cancer recurrence following conventional rectal resection is one of the most important factors that influences the 5-year-survival rate. Recent studies in anatomy have proved that rectum also has mesentery. Rectal cancer can spread in the mesorectum by many ways. These residual mini foci in mesorectum might lead to local recurrence. In 1982,Heald reported total mesorectal excision (TME) was appliable to middle and lower rectum cancers, in which a sharp dissection was performed under direct vision along a plane that separates the parietal from the visceral layers of pelvic fascia.The autonomic nerve was preserved at the same time. The TME on decreasing the local recurrence has been proved effective during these two decades and it has been widely used nowadays. Besides, it also decreases the anastomose leakage, and urinary and sexual dysfunction.


Objective To explore CT manifestations and diagnosis, and the diagnostic values of fracture of anterior cranial fossa skull basal and orbital apex. Methods With clinical and operating correlation the authors retrospectively analyzed the CT manifestations of fracture of anterior cranial fossa skull basal and orbital apex of CT axial scan in 205 cases. Results The direct sign of fracture of anterior cranial fossa skull basal and orbital apex in 205 cases showed fracture line. The orbital apex demonstrated fracture line in 71 cases.the eth- moid sinus showed fracture in 67 cases. The two accounted for 67.3%(138/205 cases). The indirect sign showed turbidity or airfluid levels in ethmoid sinus of 123 cases and pneumocephalus of 62 cases. The fracture of cranial fossa skull basal frequently complicated the other of severe cranial trauma. Conclusion In anterior cranial fossa base fracture, the position, extent, degree and type of the fracture were defined by axial CT scan. Axial CT scan is important to the clinical diagnosis of anterior cranial fossa base fracture and helpful to the diagnosis of orbital opex fracture.


The conventional way of computing the electrostatic potential at a solute charge in water, Φ ∞ (Q), includes contributions from an infinite number of water molecules. Φ ∞ (Q) varies by as large as 20 kcal/mol depending onthe summation scheme or dielectric boundary. Here we show that Φ ∞ (Q) is nonconvergent. By computing Φ(Q) as a sum of contributions from an interior, explicit water region, an intermediate, continuum water region, and an exterior, explicit water region using the same summation scheme, the two implicit water/ explicit water surface effects cancel and Φ(Q) converges to a single value, independent of the summation scheme.


Coupling beams have geometric sizes with special heights known as deep beams, and the design usually takes up more space. Focus of this research is to analyze slender coupling beams with a diagonal reinforcement angle design of less than 20 degrees to the longitudinal reinforcement. New alternative design for slender coupling beams was experimentally investigated where the parameter was the span-to-depth ratios (2.75; 3.0; 3.25). Coupling beams should not be considered as load receiver, but instead as connector between the couple shear walls for working together. The result of the test indicated that coupling beams with a slenderness ratio of 3.25 has capacity to behave as coupling beams which function is to distribute the energy.

Context: Paediatric pituitary adenomas (PPAs) are uncommon, with evidence confined to small cohorts. Aim: We aimed to elucidate the baseline profile and outcomes of PPAs in a large, contemporary, monocentric cohort. Settings, Design: Pituitary clinic at PGIMER over 8 years (2010-2018). Subjects and Methods: PPAs in patients (≤20 years at diagnosis) were included. A retrospective review of their baseline clinico-biochemical and radiological profiles and outcomes post pituitary surgery/medical management was performed. Results: There were a total of 74 patients, of which 42 were female. The median age was 15 (IQR 13-18) years. Corticotropinomas (32.4%) and somatotropinomas (25.7%) were common, with 1 case of TSHoma and pituitary blastoma. The most common presentation was headache (57%) overall and menstrual irregularities (64.2%) in girls. Most (78%) had macroadenomas. Prolactinomas showed an excellent response to primary medical therapy (83.3%). Transsphenoidal surgery was performed in 81% of patients. Diabetes insipidus (30%) and hyponatremia (26.7%) emerged as common postoperative complications. Adjuvant medical management was required in 25%, and radiotherapy in 18%. Remission rates in Cushing's and acromegaly were 62.5% and 57.8%, respectively, with long-term hormone deficits noted in one-third of patients. Conclusion: PPAs have unique features and management challenges, including effects on growth and puberty. Functional tumours and macroadenomas are common. Remission can be achieved in more than half of the patients, with endocrine deficits persisting in about a third of cases, needing long-term surveillance.


In the procedure of studying chemistry, experiment is essential; but various research had discovered that: there are still too many schools unable to provide enough experiments in regular courses. Lack of equipment, overwhelmingly consuming of chemical, insufficient fund, and safety of the experiment. These are the most popular reasons for it; but they had been used as pretexts more often. Therefore, the object of this electrochemistry-based study was to design and develop a microscale chemical experiment apparatus that makes experiment simpler, safer, more interesting, and even more helpful for learning purpose. In order to examine the value and viability of the microscale chemical experiment newly developed by this study, ninety-five 9's graders were picked from a public high school in Taoyuan. The students had been divided into 2 groups: a experimental group and a control group. The whole procedure consisted of a pre-test, teaching activities, and a post-test; by comparing the effect of this microscale chemical experiment on students' studying efficiency and analyzing students' misconceptions of electrochemistry, it can provide teacher some guides for their teaching practices. Also, in order to understand students' opinion on the new apparatus, a questionnaire-inquiry was used; eventually, ten students from each group were randomly chosen and interviewed. According to the result, obviously the experimental group achieved a higher standard compare to the control group; it revealed that the microscale chemical experiment developed by this research can promote a better concept developing and a greater learning desire more efficiently. Moreover, decent value and great interest had been found among students' respond in the questionnaire-inquiry; also, a looser schedule and ampler time had been suggested to improve the efficiency.


This chapter aims to estimate the Swedish money supply and its components for the whole period 1620–2012. There are, however, a number of issues that need to be resolved before fully consistent series on the money supply can be constructed, not least how money supply and various monetary aggregates should be defined. Money has four basic functions: medium of exchange, store of value, unit of account and standard of deferred payment. Money supply is a measure of liquidity circulating in the economy. Exactly what should be included is not given, and there are several definitions of money supply. The narrowest, M0, comprises the coins and notes in the possession of the public (the money-holding sector), while M1, M2 and M3 are broader measures, which also include various substitutes for money, mainly deposits. Moreover, the definitions of M0, M1, M2 and M3 vary between countries and over time within the same country. The international standard provided by the IMF2 is in turn an adaptation to the definitions applied in System of National Accounts 1993.3 Society is divided into sectors: the money-issuing sector, the money-holding sector and the money-neutral sector. Money supply is defined as the debt instruments of issuers in the possession of the money-holding sector. The most significant difference from various national definitions is that the money-holding sector is broader4 in that it also includes other financial institutions than banks that provide credit and receive deposits. These financial institutions are, together with banks, labelled Monetary Financial Institutions. The need of broader measures for purposes of economic analysis and policy-making is a consequence of financial innovation and deregulation since the 1970s.


In this study, power spectral estimates of the auditory evoked potentials (AEP) and peak latencies were used to predtet Intracranial pressure. Data previously collected from 12 white New Zealand rabbits were used In the study. Descriptive parameters were extracted from power spectra of the AEP, and multiple recession analyses were performed to determine the relationship between ICP and AEP special parameters. Results yield recession models of either time domain parameters (peak latencies) or frequency domain parameters (spectra)that correlate with R-square values of 0.608 and 0.758, respectively, to ICP; however, a model based on combining time domain and frequency domain parameters was the better predictor.


The Amazon shelf is an unusual oceanographic environment. In addition to the large input of fresh water from the Amazon River, unusually large tidal currents, vigorous wind-driven currents, and an impinging western boundary current contribute to one of the most energetic continental shelf environments in the world. Much of the shelf is very shallow; the 20-m isobath extends as far as 200 km from the river mouth. The proximity of the Amazon shelf to the equator means that rotational effects are much weaker than at midlatitudes.

This paper describes the extensive change management process of Gemeinschaftskrankenhaus Havelhoehe in Berlin, Germany, from a community hospital practicing mainstream medicine to a patient- and employee-centered hospital offering integrative Anthroposophic Medicine. A radical reorganisation of the hospital structure from a hierarchical to a flat organization was the central change process, resulting in the implementation of an innovative leadership-model (responsibility-teams) on a micro and meso management level. In parallel, a comprehensive training of the medical staff in Anthroposophic Medicine as well as in-house training in hospital management and leadership for the members of the newly established interprofessional and interdisciplinary 'responsibility teams' were effective strategies in the change process. The success of this change could be shown not only in a high ranking in patient satisfaction surveys but also in an increased economic efficiency, involving the highest regional growth regarding number of patients, effective cost weight, budget and a significant reduction of length of patient stay.


Based on Eysenck's theory of personality traits, this paper presents the interrelation between the personality traits of victim, the personality traits of offender and the Stockholm syndrome in The Perfect Education. It reveals that when the victim presents low moral sense and inclined to rely on others, together with the offender's reliability as well as the emotional resonance between them demonstrated in the crime, then there is higher probability for them susceptible to Stockholm syndrome. Thus, this research concludes that personality traits— particularly psychotics and neuroticism are associated with the Stockholm syndrome, and proposes some ways to tackle the syndrome.


This is a descriptive and casual correlation study.The main purpose of this research was to study the relationship between faculty members" self-efficacy and competencies with their teaching quality in branches of zone 1 of Islamic Azad University. The population of this research was 2181 faculty members. 436 faculty members were selected through random stratified cluster sampling. Data collection tools were a researchermade 27-items questionnaire for assessing teaching quality (chronbach alpha= 0.861), A researcher made 13-items questionnaire for assessing their competencies (chronbach alpha=0.866), and Schwartzer et al. questionnaire for assessing faculty members" self-efficacy. Multiple regression and Structural equation modeling were used to specify the portion of mentioned factors in teaching quality. Results showed that faculty members" self-efficacy (0.31) and their competencies (0.33) had a significant positive relationship with teaching quality. In addition, there was a significant positive relationship (0.36) between self-efficacy and competencies. The gender of faculty members had a significant effect on their competencies.


In the field of pattern recognition, combination of different classifiers is a common method to improve classification accuracy. Recently, tendency to improve the function of clustering methods, specifically partitional clustering methods, is being increased. Generally, hierarchical clustering is preferred to partitional clustering when the number of exact clusters is undetermined or when we are interested in finding the relation between clusters. Most of the proposed methods for clustering combination are based on partitional clustering. In this paper, a new method for combination of hierarchical clustering is proposed. In this method, in the first step the primary dendrograms of base hierarchical clustering methods (such as Single Linkage and Complete Linkage) are converted to matrices. Then these matrices are synthesized together in a weighted procedure and led to a final description matrix. The weights are determined based on two criteria: clustering scatter matrices and nearest neighbour of each pattern. The results show improvement in function of combination method rather than base clustering methods.

This article is aimed to determine the effectiveness of group guidance in improving understanding, attitudes, and practice of religious character values in the aspects of faith, worship, morals, and muamalah. The method used was an experiment with a pretest-posttest control group design. The population consisted of 137 people. The number of samples was 30 students with a general school or junior high school education background. Fifteen students were taken as the experimental group, and fifteen others were taken as the control group. Samples were taken by purposive sampling technique. Data were collected using a questionnaire and analyzed using SPSS 16.0 for windows. The results of the study showed that the average score of the experimental group was higher than the control group. The t-test results also showed that group guidance could significantly improve understanding, attitudes, and practice of religious character values. This means that group guidance can be used as an alternative method for building religious character.

The experimental results demonstrated the effectiveness of the methods.


Examination paper in Business Administration, School of Business, Economics and Law at Göteborg University, Accounting, Bachelor thesis, Spring semester 2007 Authors: Peter Aronsson and Anders Sjöström Title: Disclosure Requirements related to Investment Property Background and problem: The IFRS/IAS standards resulted in changes of required information from quoted companies. The standard IAS 40 implicated a possibility of valuing investment property at fair value, which has contributed to new disclosure requirements connected to the fair value model. We found it interesting to examine the real estate companies' fulfilment of the new disclosure requirements and the resources needed to fulfil the requirements. The users' opinion about disclosed information was considered interesting to examine and whether the information emanating from the new disclosure requirements ameliorated the users' possibility to valuate investment property. Purpose: The thesis should describe and analyze the disclosed information regarding investment property provided by the real estate industry. To be able to fulfil the main purpose the study will examine the fulfilment of the disclosure requirements, describe resources demanded to meet the increased demand of information and examine if the disclosed information by the real estate companies corresponds to the users' needs. Method: The study has a combined quantitative and qualitative approach. Secondary data sources consisted of the annual reports from the 15 real estate companies quoted on OMX Nordic Exchange Stockholm holding investment property. Primary data consisted of six interviews representing real estate companies, banks and analysts. Results and conclusions: The fulfilment of the disclosure requirements varies. The balancing of carrying amounts is an area where the companies are proficient in disclosing essential information. The examination has also found four areas where shortages could be distinguished: (1) the criteria to separate investment property, (2) specification of direct costs contributed or not to rentals, (3) variables used in the valuation model and (4) disclosing essential risks and uncertainties. The resources needed to meet the increased demand for information have increased and the study has found the solutions being reallocation, rationalization and consulting external experts. The users are mainly satisfied with the disclosed information but would like more information related to the valuation of investment property and project property. Sensitivity analysis is a tool enabling a quick overview of the company's influencing factors but a standardisation of the parameters would be preferable. Recommendations for future research: Three areas where demands for future research have been distinguished are: What expenditures related to investment property should be capitalized? How should an appropriate formation of tax on investment property be formulated? Should sensitivity analyses be required and is a standardisation feasible?

Abstract This paper suggests the Multivariate Partial Distribution (MPD) for the first time, and establishes the new kinds of models for pricing the group assets (MPGA) based MPD, in which the competition and complementarity in cost resources are analyzed, and the way of dividing an asset into two assets is discussed. According to this study, integrated risk of group assets may be analyzed into two types - hedging risk and independent risk, for which corresponding representing models are given. Then, we could analyze the price risk and profit of the group assets in a more specific way. This study indicates that in most cases, a simple combination of assets hedging in the one-to-one mode cannot eliminate completely their market risks in any case, and puts forward a particular method of determining the optimal ratio between underlying asset and its derivative in hedging.


With the tremendous growth of the Internet and the continuous increase in malicious attacks on corporate networks, Intrusion Detection Systems (IDS) have been designed and adopted by organizations to accurately detect intrusion and other malicious activities. But these IDSs still suffer from setbacks such as False Positives (FP), low detection accuracy and False Negatives (FN). To enhance the performance of IDSs, machine learning classifiers are used to aid detection accuracy and greatly reduce the false positive and false negative rate. In this research we have evaluated six classifiers such as Decision Tree (J48), Random Forest (RF), K-Nearest Neighbor (K-NN), Nave Bayes (NB), Support Vector Machine (SVM) and Artificial Neural Networks (ANN) on three different types of datasets such as NSL-KDD, UNSW-NB15 and Phishing dataset. Our results show that K-NN and J48 are the best performing classifiers when it comes to detection accuracy, testing time and false positive rate.


This paper analyzes the gender wage gap among rural-urban migrants in 13 cities and their metropolitan areas in Colombia. In particular, it is demonstrated that the difference between male and female wages are wider when the comparison is made exclusively with the rural-born women. This suggests that wages paid to rural women are consequence of a double penalty; one for being women and another one for


Pure aflatoxins and deliberately infected yellow corn and peanuts with Aspergillus flavus were separately exposed to gamma radiation at 5, 10 and 20 KGy. The levels of pure B 1 were the most radio-sensitive while B 2 was the most radio-resistant compared with the other isomers. B 1 and G 1 toxins were completely destroyed at irradiation doses of 10 and 20 KGy, respectively. The reduction percentages of aflatoxins in the deliberately infected yellow corn and peanuts demonstrated that the aflatoxins B 2 and G 2 were the most radio-sensitive than that of their analogy compounds B 1 and G 1 . The toxicity index values for the infected yellow corn and peanuts were decreased by increasing the irradiation dose. The gamma rays even at 20 KGy were not effective in destroying completely the toxins since only 83% reduction of aflatoxins was achieved.

The use of foreign-bred bulls leads to changes in the genetic structure of the black-and-white breed population, which affects the level of population characteristics. The study was conducted to study the comparative variability and heritability of productive and reproductive characteristics of daughters of sires of domestic and foreign selection in pedigree livestock 10 250 cows 1st calving modern population of black-motley breed of the Vologda region. The superiority of the offspring of foreign bulls in the average indicators of all the studied traits was established with confidence (P<0,001). There were no significant differences in the level of variability of the characteristics of the descendants of domestic and foreign bulls. According to productive traits, the greatest variability of indicators was established for milk yield for 305 days of the 1st lactation Cv = 17,3 – 17,7%, therefore, selection on this trait will be more effective. The greatest share of the influence of bullsfathers, both domestic and foreign selection, in the total sum of all factors determining the value of traits in the population of the black-and-white breed, is determined by the milk yield of daughters η2 = 0,22 – 0,24, the age of the 1st fruitful insemination and the first calving η2 = 0,24 – 0,25. In further breeding work with the breed, it is necessary to obtain and use domestic producers that exceed the breeding value of foreign bulls.


e12510 Background: Despite the important progress in the treatment of solid tumors, high grade gliomas (HGGs) remain neoplasm with poor prognosis, especially when are not radically resected. Here we report the results of a selected population treated with standard schedule of Radiotherapy (RT) + Temozolomide (TMZ) followed by TMZ until progression. Methods: From January 2008 to January 2010, 14 newly diagnosed HGG patients, with median age of 50.6 years (range 27-75 yrs), were enrolled at Oncology Unit of S. Maria Goretti Hospital in Latina (University of Rome "Sapienza"). All patients were not radically resected and with ECOG PS=O. Furthermore patients were selected according to O6 Methyl-Guanine-DNA-Methyl Transferase (MGMT) promoter methylation status. Only methylated patients were included in our study. After surgery, patients received standard treatment with TMZ (75 mg/m2) concomitant with RT (60 Gy total dose). After a break of six weeks, Magnetic Resonance Imaging (MRI) was performed and all patien...


D ermatomyositis (DM) is an autoimmune systemic disease. It is part of the spectrum of idiopathic inflammatorymyopathies, affecting skin, muscle, and blood vessels. The most frequent cutaneous features are violaceous erythematous papules over the dorsal metacarpal and interphalangeal joints of the hands (Gottron papules); violaceous erythema over the extensor surfaces of the hands, elbows, knees, and ankles (Gottron sign); heliotrope rash; and shawl sign. A less common manifestation of DM is panniculitis, which refers to inflammation of the subcutaneous tissue. We present a 30-year-old woman in whom panniculitis was the first cutaneous manifestation of DM. Three years prior, the patient presented with painful, erythematous, and swollen skin nodules on the external side of the upper arms (Fig. A). At that time, skin biopsy was consistent with lobular panniculitis. One year later, the patient was referred to the Rheumatology Unit with heliotrope rash, "shawl sign," and proximal upper and lower extremities weakness. Laboratory tests showed increased creatine phosphokinase (1623 IU/L), aspartate aminotransferase (257 IU/L), alanine


It is well recognized that semantic conflicts are responsible for the most serious data heterogeneity problems hindering the efficient interoperability between heterogeneous information sources. In recent years, ontologies are widely used as a means for solving the information heterogeneity problems because of their capability to provide explicit meaning to the information. Several organizations are undertaking the development of domain specific ontlolgies to resolve the semantic ambiguities between various domain specific representations. These ontologies designed for a particular task could be a unique representation of their project needs. Hence, there arises a need to align heterogeneous ontologies to facilitate meaningful knowledge interchange between various sources. Thus, ontology mapping has emerged as an important requirement to enable semantic interoperability between different representations within a domain. In this paper we focus on the semantic heterogeneities present in the coastal information sources whose data are highly heterogeneous in syntax, structure and semantics. Ontological modeling was carried out for the various information sources. A data mining approach was adopted to align the concepts belonging to various land cover ontologies. We present a set of standardized information services and middleware for seamless access to information from various networks.


In this paper, we explore prenuclear and nuclear fundamental frequency (F0) patterns and durational cues in Czech neutral yes-no questions and compare them with (neutral) statements. The data were obtained in a production experiment with 21 native speakers and later described phonetically and modeled within the Autosegmental Metrical (AM) framework. Despite of the fact that the final rise distinguishes Czech polar questions from statements, we found additional significant differences in prenuclear positions: The initial accentual phrases have a larger pitch excursion and longer duration in statements than in questions. These findings thus support the claim that prenuclear tonal patterns should be taken into account in the analysis of sentence modality.


In this paper,the non-linear least squares data fitting method for the AM-FM model of the the gravity tide IMF signal is proposed.Firstly,the AM-FM model is decomposed amplitude modulation signal and frequency modulation signal which is fitted by using the non-linear least squares method separately.The fitting number is determined by the correlation coefficient.Then the IMF signal of the gravity tide is fitted by the AM-FM model.The experimental results show that the gravity tide IMF signal can be well described by the AM-FM signal.A foundation is established for further discussion its characteristic such as the cyclostationarity.


Aim: Among the planktonic microcrustaceans, copepods Cyclopoida and Calanoida are the most representative groups, being the largest biomass of the plankton community. The aim of this work is to catalogue and analyze the distribution of copepod species (Crustacea, Maxillopoda) in pelagic and littoral zones from small reservoirs in the northwest of the Sao Paulo State, in dry and rainy seasons (2007 and 2009). Methods: Zooplankton samplings were carried out in littoral and pelagic zones of 13 small shallow reservoirs (mean depth: 2.6 m) using vertical hauls and plankton net (45 µm). Water physical and chemical parameters were also monitored with a multiparameter Horiba ® U10. Results: Eighteen species of copepods were identified, 13 Cyclopoida and 5 Calanoida. There was no statistical difference between the distributions of species from the littoral and pelagic zones and neither between dry and rainy seasons. Three species occurred exclusively in the littoral zone - Eucyclops elegans, Paracyclops chiltoni and Mesocyclops ogunnus. Tropocyclops prasinus and Thermocyclops decipiens were the most frequent species in the studied environments. Conclusion: Our data suggest that in shallow reservoirs copepods present a homogeneous distribution between the littoral and pelagic zones and Cyclopoida are more diverse than Calanoida. Shallow depths and eutrophic state may be regarded as limiting conditions for the development of Calanoida in these reservoirs.


12 adjustments are made, then the resulting inequality will be a proper bound at a calculable level of signicance. In other words, satisfaction of such a variance-adjusted schema theorem will assure that the probability that a schema loses proportion in some generation is below some specied amount. When done properly, these calculations lead to rigorous convergence proofs for genetic algorithms. The calculation of the previous section assumed that the variance of a particular schema's tness can be obtained from the uniform, full population value. That value is representative of the value we should expect in sampling a large population, but a better value can be obtained by calculating the variance of a schema's tness directly in a population of known distribution. Dening a proportion-weighted tness value (x) = f(x)P (x)2 l as in Bridges & Goldberg (1989), the calculation of variance proceeds immediately if we recognize that we must multiply two dierent Walsh expansions, one for f (the usual transform, w i) and one for (the transform of proportion-weighted tness, call it w 0 i). The mathematics follows exactly as in section 3, except that the terms of f 2 involve only products of the w 0 i terms, while the terms of f 2 involve a products of w i and w 0 j terms. As a result the overall sum does not collapse to a single sum over a dierence of index sets. Nonetheless, the structure of the terms present in the two sums (the ordered pairs in J 2 8 and J 2) is the same as before, because the index sets are the same. 5 Conclusions This paper has presented, interpreted, applied, and extended a method for calculating schema tness variance using Walsh transforms. For some time, genetic algorithmists have been content to use results in expectation such as the schema theorem. Serious eorts at rigorous convergence proofs for recombinative GAs demand that we consider variance of the function, variance of the operators, and other sources of stochasticity. Some of these issues have been tackled here, and a rigorous approach to the others has been outlined, but it is apparent that this line of inquiry clears a rst path to fully rigorous GA convergence theorems for populations of modest size.


Calf coronavirus (viral diarrhea) is an endemic disease that is mainly spread by maternal infectivity, cold, wet conditions and crowded housing conditions.
Feces were sampled from the rectum of 50 newborn, 3-35-day-old calves. The samples were examined by microbiological, hemagglutination and Bovine enterichek accelerated test (antibody strips) in the ANAU Research Center of Veterinary Medicine and Veterinary Sanitary Examination. Epidemiological data, manifestations of clinical symptoms, patho-anatomical changes, hemagglutination reaction and Bovine enterichek test were used to identify the infection of 3-35-day-old calves. Feces with mucus content from the rectum of calves with diarrhea (50 samples), internal organs (spleen, liver, etc.) and affected small intestines of fallen 3-7-day-old animals (3 heads) were examined.
During epidemiological studies, an increase in body temperature (42 0 C), anorexia, exhaustion, depression and watery-slimy diarrhea were observed in sick calves. Clots were found on the walls of the arteries of dead animals, inflammation and hemorrages were found in the lymph nods and kidneys.
According to epidemiological, clinical symptoms, patho-anatomical changes, microbiological research, as well as hemagglutination reaction and Bovine enterichek rapid test data, both coronavirus and enterobacterial diseases were detected in animals at the same time. As a result, farmers and villagers suffered economic losses due to newborn calf falls.
The disease was diagnosed according to hemagglutination reaction, Bovine enterichek test and microbiological methods. Morbidity and mortality rates were respectively 0.1 (10 %), 0.6 (60 %), economic loss – AMD 209 400.
Based on the effectiveness of the "BolsheVac" ("БольшеВАК") vaccine, we propose to carry out preventive vaccinations in vulnerable farms.


In tracing the development of the recruiting system, Alan Jeeves shows how a large proportion of the labour supply came to be controlled by private labour companies and recruiting agents, who aimed both to exploit the workers and to extract heavy fees from the employing companies. The gold indusry struggled for years against the internal divisions which created the competition for labour, until at last the Chamber of Mines, with the support of the state, succeeded in driving out the private recruiters and centralizing the system under its control. This study of the interests involved in the struggle for control of the black labour supply reveals much about the forces which created and now entrench racial domination in South African's industrial economy.

Justice Byron R. White was one of the most talented persons I have ever had the privilege to know. A brilliant thinker, writer of uncommon economy, and storied athlete, White had the innate personal skills to accomplish pretty nearly anything he set his mind to. Yet, in the year I spent as his law clerk and the years thereafter until his death, the quality that impressed me the most was his modesty. He never boasted about what he had done or could do, and he never told stories with the implicit purpose of glorifying some aspect of his past. When my co-clerks and I would ask questions of great curiosity about some of the famous people he had known over the years, his responses would be respectful and occasionally surprising. But they invariably placed the other person at the center of the story and not himself. As a role model both personally and professionally, he served as a daily reminder that hard work, conscientious attention to duty, and genuine respect for others are values that produce their own rewards distinct from the more ephemeral psychic lift of praise and recognition. I first glimpsed Justice White's distinctive modesty when we met in 1990. When he called to invite me for an interview to be his law clerk, I was clerking in San Francisco for Judge Joseph T. Sneed. The Justice invited me to travel to Washington within the next week, cautioning that it was no sure thing that I would get the job but saying he would understand if I thought the cost too great for the opportunity. Of course, any young lawyer would jump at that chance, expense be damned. After I had flown a total of 6,000 miles for an interview that lasted barely eighteen minutes, I can still remember the excitement I felt at his subsequent call a few weeks later offering me the clerkship, which he prefaced by saying, "I'm getting pretty old. You never know whether I'll make it or not, and you may want to take a job with a younger Justice." Perhaps because lightning seemed to strike with regularity in his own life, he was just unaware that I might not want to risk it striking more than once in mine. Nor after having met him would I have wanted it to.


An understanding of the spatial dimension of economic and social activity requires methods that can separate out the relationship between spatial units that is due to the effect of common factors from that which is purely spatial even in an abstract sense. The same applies to the empirical analysis of networks in general. We are able to distinguish between cross-sectional strong dependence and weak dependence. Strong dependence in turn suggests that there are common factors. We use cross unit averages to extract both national and regional factors and contrast this to a principal components approach widely used in the literature. We then use thesholding to determine significant bilateral correlations (signifying neighbours) between spatial units and compare this to an approach that just uses distance to determine units that are neighbours. We apply these methods to real house price changes at the level of the Metropolitan Statistical Area in the USA. JEL Classification: C21, C23


By 1919, Albert Einstein's thoughtful but absent-minded friend, Michele Besso, had lost all of his copies of Einstein's publications. He then suggested that Einstein publish an edition of his collected works, with an introduction that 'would convey which works were already familiar to you at the beginning of your work: Boltzmann, Lorentz (precisely which of their writings), then Planck (precisely which writings)'. Nothing came from this request. Also in 1919, Ludwig Darmstadter asked Einstein to bequeath his entire correspondence to the Prussian State Library. Einstein then agreed to contribute only 'the letters worthy of preservation', though ultimately his papers did not end up in Berlin. After his death in Princeton in 1955, his close friend economist Otto Nathan and his devoted secretary Helen Dukas, as Trustees of his Estate, laboured to collect and organise his documents to make them eventually accessible to the public. Einstein had appointed Nathan as sole Executor of his Estate, and hence Nathan operated conscientiously to administer materials and to facilitate publication in many languages. Selected collections of Einstein's publications had been issued in Japanese and Russian, but nothing comprehensive. For years, Gerald Holton of Harvard University earnestly laboured to help Dukas to catalogue, describe, and microfilm many documents. By the late 1970s, the long project of publishing Einstein's collected papers finally began. I will review the entire series to date, 12 volumes, focusing on the latest volumes but first describing the early days of the Einstein Papers Project. Einstein worked at the Institute for Advanced Study (originally housed at Fine Hall of Princeton University) for 21 years, until he died. Hence, the Director of its academic Press, Herbert S. Bailey Jr, enthusiastically led an effort to publish Einstein's scientific papers. But Nathan convinced him that they should publish not just the science but all of Einstein's writings, believing, in particular, that Einstein's writings on peace would eventually be regarded as more important than his physics. In 1971, the Einstein Estate finally reached an agreement with Princeton University Press to publish the complete 'Writings of Albert Einstein'. For years, they collaborated to plan the enormous project (they guesstimated roughly 10,000


EVERY EMERGENCY MEDICAL SERVICE - SMU - WHICH FUNCTIONS CORRECTLY SHOULD BE ABLE TO PROVIDE WITHOUT DELAY A SUITABLY EQUIPPED AMBULANCE TO ADMINISTER THE NECESSARY FIRST-AID TO THE CASUALTY AT THE SITE OF THE ACCIDENT, TO STABILISE THE CONDITION OF THE CASUALTY ON THE WAY TO THE HOSPITAL, TO SELECT THE HOSPITAL BEST EQUIPPED TO PROVIDE THE REQUIRED TREATMENT FOR THE CASUALTY. AN ATTEMPT WAS MADE TO EVALUATE AN SMU QUANTITATIVELY BY USING FACTORS DIRECTLY DETERMINING ITS EFFICACY, SUCH AS: THE RATE OF SURVIVAL OF CASUALTIES; THE DEGREE OF REHABILITATION; THE DIMINUTION OF SUFFERING; THE RATES OF MORTALITY OR PHYSICAL INCAPACITATION. THESE ATTEMPTS PROVED TO BE IMPRACTICABLE BECAUSE OF THE DIFFICULTY OF MEASURING THE RESULTS, FOR THE PATIENT, OF USING THE EXISTING LOCAL SMU IN COMPARISON WITH AN OPTIMAL SYSTEM. IN ORDER TO OVERCOME THESE DIFFICULTIES, A METHOD OF EVALUATION WAS DEVISED IN ACCORDANCE WITH WHICH ATTENTION IS DIRECTED TO PARAMETERS WHICH HAVE A READILY APPRECIATED BEARING ON THE EFFICACY OF THE SYSTEM AND WHICH CAN BE RELATED TO THE ELEMENTS AND SUB-ELEMENTS OF THE SMU SYSTEM.

The popular belief is that environmental regulation must reduce employment, since such regulations are expected to increase production costs, which would raise prices and thus reduce demand for output, at least in a competitive market. Although this effect might seem obvious, a careful microeconomic analysis shows that it is not guaranteed. Even if environmental regulation reduces output in the regulated industry, abating pollution could require additional labor (e.g. to monitor the abatement capital and meet EPA reporting requirements). It is also possible for pollution abatement technologies to be labor enhancing. In this paper we analyze how a particular EPA regulation, the so-called "Cluster Rule" (CR) imposed on the pulp and paper industry in 2001, affected employment in that sector. Using establishment level data from the Census of Manufacturers and Annual Survey of Manufacturers at the U.S. Census Bureau from 1992-2007 we find evidence of small employment declines (on the order of 3%-7%), which are sometimes statistically significant, at a subset of the plants covered by the CR.

An aircraft nacelle includes an air intake followed at the upper part by a part that is integral with the mast, called a cap, and at least one door with a curved profile that includes a stiffening device arranged at the edge upstream from the door and which includes: a flexible element that follows the curved profile of the door between two remote anchoring points, at least one safety index including a latch pivotable around an axis of rotation, and connected to the door so as to occupy a locked position in which the end of the latch rests against the inside surface of an edge upstream from the door, and an unlocked position in which the end of the latch is offset relative to the edge, whereby in the locked position, the latch prevents the scooping phenomena by limiting movements of the door in the radial direction toward the outside of the nacelle, and elements for stretching the flexible element between the two anchoring points and for controlling the pivoting in the locked position of the latch.


The factors determining the position and the width of the focused zone in the tapered capillary, where the applied longitudinal electric current causes the temperature gradients and related pH gradients, are analyzed. The optimal conditions for this thermal isoelectric focusing at the initial stage of the research are formulated. These conditions include limitations for the temperature, the electric current and the electroosmotic flow in the tapered capillary. Further, the possibilities of more sophisticated selection of the system parameters are discussed, when a mutual compensation of the factors, which shift and spread the focused zone, may be used. This situation may be used for the isoelectric focusing process with a higher efficiency and for the wider separation parameters range.


Based on Generalized Minimal RESidual(GMRES) method and regularization technique,a new image restoration method is presented.The method is based on the Arnoldi process,which yields a sequence of smaller least squares problems to approximate the original ill-posed problem.Truncated Singular Value Decomposition(TSVD) regularization is used to solve these least squares problems stably.According the characters of image restoration,L-curve criterion is modified while selecting iteration in TSVD method.Numerical results illustrate good restoration effect.


In this work we prove a global well-posedness result for a tridimensional rescaled Boussinesq system, with positive full viscosity and diffusivity parameters in the framework of critical Fourier-Besov spaces. This rescaled approach permits to know the behaviour of the system according to relations between both the parameters and the initial velocity and temperature; for instance, it is possible to consider, for small enough viscosity and large diffusivity, a large enough critical Fourier-Besov norm for the initial temperature and it is also possible to consider, for small enough diffusivity and large viscosity, a large enough critical Fourier-Besov norm for both the velocity and the temperature.

Abstract In the long standing academic world, academic loath fashion, so it is either in the critical mode such as Veblen's sense that luxury is for upper class to distinct themselves from other social class through the luxury goods It is to show one's ability to show consumption ability. The luxury good is symbolic in that it not only the good itself, but also the shopping experience.


Abstract Intimate relationships are an integral part of our lives, but the rate of relationship breakups is high. We explored the role of the investment model and the traits that influence investments on relationship satisfaction among 146 volunteers (age M = 28.76 years, SD = 10.23). Relationship satisfaction was predicted by investments, which in turn were predicted by attachment, personality and love style. Clinicians working with individuals or couples with relationship issues may benefit from knowing how invested they are in the relationship and their love style. Insight into imbalances in these constructs between partners may be used to facilitate relationship satisfaction.


Understanding the relationships between vertical velocity, anisotropic parameters , δ and traveltime is important both for parametrization of waveform inversion and proper interpretation of waveform inversion results. Forward modeling indicates that traveltime is more sensitive to vertical velocity and than to δ. This suggests that δ may be fixed during an inversion for vertical velocity and . When vertical velocity and are directly parametrized, changes little during the inversion. A more balanced sensitivity kernel can be obtained by using different parametrizations, such as the vertical and horizontal velocities, or the logarithms of slowness and .


By comparing with the European Prestandard Eurocode 8, it is analyzed that the rationality of "strong shear-weak bending" for seismic fortification measures for concrete structures in China, and it is recommended that it be added details of seismic design by using diagonal shear reinforcement to safeguard beams against sliding shear failure, when the Positive-Negative shear force is reverse and the ratio is high.


There are many aspects of shear stud behaviour that may affect a heated steel-concrete composite structure in fire such as stud layout, ductility and strength; heated material behaviour; loss of composite action through the failure of multiple studs; and so on. This paper attempts to understand the role of shear studs on full structural behaviour in fire during both heating and cooling. Predictions of stud behaviour at ambient temperature using numerical models are first compared to experimental work to benchmark the modelling approach. A good correlation is found. This is followed by the analysis of full structural behaviour in fire where shear stud properties are varied parametrically. Individual shear studs are modelled so it is possible to identify which studs fail and at what point in the fire. The results demonstrate the importance of ensuring continued composite action in fire.


The thermal valorization of high calorific-value, regenerable raw materials and waste is inevitably gaining in significance. This article examines various ways of increasing efficiency and cutting costs in the field of power generation. Pyrolysis, and also gasification processes, make it possible to generate a high-value pyrolysis gas for use as a secondary fuel for co-combustion in industrial combustion systems. The byproducts are solid residues, coke, on the one hand, and high-value raw materials, such as metals and inerts, on the other. In both processes, heat recovery for air or air/steam-mixture preheating helps in the achievement of a useful increase in efficiency The effective use of EcoReg® rotary bed regenerators in a pyrolysis and in a gasification process are discussed. These processes involve, on the one hand, direct and, on the other, indirect heating.


Based on the catch records of"YUE DIAN YU NO. 42212"from August 2012 to June 2014,we studied the catch composition and fishing season by steel light falling-net fishing vessels in the South China Sea. The results show that Sthenoteuthis oualaniensis,Carangidae,Scombrid,Loliginidae and Trichiurus japonicas were the main catch species,accounting for 69. 8%,12. 6%,7. 3%,3. 9% and 3. 5% of the total catch,respectively. The fishing ground could be divided into continental shelf waters and deep waters of high seas. Main catch species in shelf waters were Carangidae,Loliginidae,Trichiurus japonicas and Scombrida; the main catch species in deep waters was Sthenoteuthis oualaniensis,which was less diverse. The fishing season in shelf waters was from August to February in the next year( 1 ~ 20 fishing days per month and 10 d averagely; the average catch per day in one month was 370. 5 ~ 3 670kg·d- 1and 1 152. 0 kg·d- 1averagely). The fishing season in deep waters was from February to June( 1 ~ 30 fishing days per month and 13 d averagely; the average catch per day in one month was 1 000. 0 ~ 10 190. 0 kg·d- 1and 4 071. 3 kg·d- 1averagely). Since the fishing operation in deep waters had higher productivity and more total catch than those in shelf waters,it is necessary to develop steel light falling-net fishing vessels to explore the fishery resources in deep waters of high seas.


Last November (2020) the SIGCAS executive board conducted a survey of SIGCAS members to get a picture of who we are, where we come from, what we're interested in, and what the membership would like to see the board do to better fulfill its mission. Based on discussions with the executive board, SIGCAS Vice Chair Lisa Kaczmarczyk implemented the survey using Survey Monkey. As with all surveys one can't get all the information one would like and the more information one tries to obtain, the fewer people are likely to supply it. We settled on eight questions and we received input from 68 people, about 23% of our membership (then just under 300 people---now slightly over). What follows is a presentation of the survey results along with some commentary. How I interpret the data and what I think ought to (or could) be done with the data might not be how you'd interpret the data and think about what ought to be done. And that's a good discussion to have! At any rate, the responses that we've received represent a valuable part of our collective intelligence, consciousness, and visions for the future. The hope is that these will inform out work going forward. Please note that I'm not doing any professional analysis since I'm not qualified to do that. I also suspect that the wisdom we can glean wouldn't be found via additional number crunching. And I would also add that there are dangers to reading too much into survey data. As a precaution I have asked the other board members to take a look at this article so I don't get anything terribly wrong. Just a reminder that the data we have doesn't necessarily reflect the totality of what our entire membership would provide. (Although, as one somewhat validating figure, the percentage of people outside of North America on our roster is about the same as the percentage of people who told us they were from outside North America on the survey, 72%.) Also, I'm trying to avoid the temptation to comment on everything. There's too much material for that. And, obviously, there are too many suggestions and ideas out there for SIGCAS to move on all of them. But based on these responses a multitude of useful information is now available and it should help lead us into productive discussions and actions.


The present study evaluated the effects of replacing fish meal (FM) with soya bean meal (SM) or fermented soya bean meal (FSM) on growth, nutrient utilization, digestive enzyme activity and intestinal histology of Pacific white shrimp. The basal diet (control) contained 18% FM, and then, FM in basal diet was replaced by 1/6 (17%), 1/3 (33%) and 1/2 (50%) by the inclusion of SM and FSM, referring to SM17, SM33, SM50, FSM17, FSM33 and FSM50 respectively. The shrimp (3.0 g) were fed one of the seven diets for 8 weeks. The results showed that the control group had the highest weight gain (WG) (653.8%) and the lowest feed conversion ratio (FCR) (1.61). SM33, SM50 and FSM50 groups showed significantly lower WG, crude protein (CP) digestibility, hepatopancreatic protease, amylase activity and higher FCR than the control (p < .05). The villi height of SM33, SM50 and FSM50 groups and the intestinal wall thickness of SM groups and FSM50 group were significantly lower than those of the control (p < .05). In conclusion, fish meal (18%) in white shrimp diet could be replaced by 1/6 (17%) and 1/3 (33%) with SM and FSM respectively. Fermented soya bean meal could replace more fish meal than soya bean meal did.


In the present study, we present a bio-mimetic flow control device, AMD (Automatic Moving Deflector), for drag reduction of a three-dimensional model vehicle. The model vehicles considered are GM model (from GM company) and Ahmed body. The GM model is modified such that it contains a slant part at its base. The present bio-mimetic flow control device is inspired by the secondary feathers of a bird wing which passively pop up at landing, and is installed at the critical slant angle of each model, at which the drag coefficient is the highest. The experiment is conducted in a wind tunnel at Re H = 1.3 × 10 5 - 3.8 × 10 5 , based on the model height H. To investigate the drag reduction by the AMD, we measure the drag force on each model vehicle with and without the AMD. With the present AMD, the drag coefficient is decreased by up to 7% and 20% on the GM model and the Ahmed body, respectively. To investigate the mechanism of the drag reduction by the AMD, we measure the wall-pressure at the slant surface and the vertical base of each model. We also measure the velocity field around each model using particle image velocimetry. The wall-pressure and velocity measurements indicate that the drag reduction by AMD results from the separation delay caused by the AMD.


This article tries to review of Spainish and Latin American historical studies of Korea during the past two years. The researchers of Spainish and Latin American history have studied a wide variety of subjects. Despite of the lack of the researchers, Spainish and Latin American historical studies of Korea made a notable achievement like qualitative deepening and expansion of research fields over the two years. In the Spainish historical studies, the researchers intensified the quality level of existing research subjects like ethnics minorities of Castile, the Inquisition, Franco Regime, expansioning into new areas of research such as anarchism, Mondragon, ETA and so on. In the Latin American hitorical studies, the researchers improved our understanding of the indigenous people and populism. Furthermore they approached a new topic like Latino, the Transatlantic relationship etc. One of the promising perspective of Spainish and Latin American historical studies of Korea is a deepening of the quality level of existing studies. The other is a popularization of Spainish and Latin American historical studies. And to do so, first of all, the researchers have to intend to approach a theme from our own viewpoint. Then, they must make an effort to write and translate general statements and books of major. If do so, the future of Spanish and Latin American hisotical studies of Korea would be promising.


The engine of much of the growth in the sector of the global clean energy comes from renewable sources such as sunlight, wind, geothermal, hydro and primarily is due to political changes and private investment to generate new sources of energy electrical clean. In our country a priority of the central government today is to promote the growth of large hydroelectric potential of the country, located especially in the eastern
cordillera of the country, where resources and potential exist. It is therefore critical that state and private institutions to take a leading role in the energy sector, mainly in hydropower development, taking into account the current energy deficit and the marginal cost of energy, which makes it extremely attractive to the especially private investment. Universities through their students can also support the studies of pre-feasibility and
feasibility of hydropower projects under the guidance of their faculty qualified for that reason has made the design and simulation of a hydroelectric plant, to obtain clean electricity from the bed of the river bed.

The research vehicle for this contract is the largest possible computer that could be conceived for the mid to late 1990's. The technical challenges of such a machine serve as our guiding stimulus for the research carried out and reported here. We imagine this machine to occupy a 14-story building, to cost upward of $1 billion, and to be so colossal that the nation could only afford one or two of them. The available chip technology and machine size are consistent with 10 to the 15th power FLOPS and 10 to the 15th power bytes of memory. The machine will be used to solve large-scale scientific problems having both military and civilian applications. This investigation addresses the hardware technology, software techniques, algorithms, communications, processing elements, and applications. The study will determine the plausibility (not feasibility) of the machine. Progress in these various areas are highlighted in the forthcoming sections. (rrh)


ABSTRACT The purpose of this study was to determine the storage characteristics of Sulgidduk, a kind of rice cake, added with Portulaca oleracea L. The effect of P. oleracea L. paste (0, 1, 3, or 5%) on the storage qualities of Sulgidduk was evaluated during storage period at 20±2°C for 3 days. As the amount of P. oleracea L. paste increased, loss of water in P. oleracea L. Sulgidduk decreased. Textural properties by texture profile analysis showed that hardness of Sulgidduk added with 5% P. oleracea L. paste was the lowest among treated samples. However, the hardness of all Sulgidduks increased during storage, regardless of the addition amount of P. oleracea L. paste. In accordance with the texture results, differential scanning calorimetry exhibited that the enthalpy of Sulgidduk with 5% P. oleracea L. addition was the lowest, indicating the delaying effect of P. oleracea L. paste on retrogradation of rice cake. From these results, the addition of P. oleracea L. to Sulgidduk extended shelf-life by delaying retrogradation.


Are due to the large number of subscribers who have, in response to our appeal for money, so promptly forwarded their dues. This we felt sure they would do when made aware of our wants in the premises. As we are obliged to pay our publisher cash for every number as soon as it is issued, we know all our friends appreciate the situation and rejoice to lend us a helping hand. A few subscri bers are still in arrears. We know they, too, will appreciate our difficulties, (with a money panic to increase them,) and hope very soon to have the pleasure of " squaring" all subscriptions on our books. It is also necessary to make full settlement for the year in order to commence the coming year unembarrassed. We trust all who owe us will remember this, and oblige us by forwarding their dues without delay.


The Classification for Pap smear Diagnosis aims at classifying the Pap smear cells whether it is affected or not. The term "Pap-Smear" refers to samples of human cells stained by the so-called Papanicolaou method. The Papanicolaou method is a medical procedure to detect pre-cancerous cells in the uterine cervix. The median filter is used to remove the noises in the cell, and then the features are extracted using gray level co-occurrence matrix technique. k-NN classifier, Baye's classifier and ANN classifiers are used for the classification problem.. The classified cells are normal and abnormal.


Abstract : A detailed evaluation of one untoughened epoxy baseline resin three toughened epoxy resin systems was performed. The Hercules 3502, 2220-1, and 2220-3, and Ciba-Geigy Fibredux 914 resin systems were supplied in the uncured state by NASA-Langley and cast into thin specimens and round dogbone specimens. Tensile and torsional shear measurements were performed at three temperatures and two moisture conditions. Coefficients of thermal expansion and moisture expansion also measured. Extensive scanning electron microscopic examination of fracture surfaces was performed, to permit the correlation of observed failure modes with the environmental conditions under which the various specimens were tested. A micromechanics analysis was used to predict the unidirectional composite response under the various test conditions, using the neat resin experimental results as the required input data. The mechanical and physical test results, the scanning electron microscope observations, and the analytical predictions were then correlated. jg p262


Modern views of poetry tend to concord with Wallace Stevens's insistence that "God and the imagination are one," assuming that the only meaning there is in the natural world is that which the poet makes. But Denise Levertov held instead that the poet's word is a response to the beauty of the world as given by God, and that the poet's task is to invite the reader to resonate with that experience. Drawing on current research from neurocognitive poetics that indicates how readers experience beauty in language, this essay seeks to demonstrate how Levertov's poem, "O Taste and See," embodies an invitation for the reader to engage one's senses in the discovery of God through the beauty of poetry and created being.


Among passive energy dissipation devices, friction dampers are used worldwide as means of increasing damping into structural building systems with the aim to reduce the seismic response. These devices, added either in-line with diagonal braces, or at the intersection zone of X- and chevron-bracing and installed in moment frame buildings, can reduce the demand of the primary frame system, the interstorey drift, and control the damage of non-structural components as building envelope. Regarding to their mechanical behavior, friction dampers dissipate energy through the relative sliding of plates clamped with post-tensioned bolts, while slipping occurs along the length of the slotted hole. This device reveals a rigid-plastic behavior defined by three phases such as: "stick-slip" before sliding occurs, "slipping", and the "slip-lock" when the force in the device increases due to the bearing of the post-tensioned bolts.
Thus, the first part of this study is focused on establishing a computer model able to simulate the three-phase behavior of the friction damper installed in diagonal bracing by using OpenSees software framework. In light of this, the Bouc-Wen material characterized by smooth transition from elastic to plastic was calibrated through parametric study and employed to characterize the first two behavioural phases mainly controlled by the slip-force and available slip-distance. In addition, earlier experimental studies conducted by Pall (1979) were used to control the calibration. To simulate the slip-lock phase exhibited due to bearing of post-tensioned bolts, gap-elements were added in parallel to the Bouc-Wen model. In addition, to complete the friction-damped brace model, the action in series of the elastic brace and the friction damper model is considered.
The second part of this study illustrates the behavior of the 4, 8 and 12-storey building designed as moderately ductile (MD) moment resisting frame structure accordingly to NBCC 2010 and CSA/S16-2009. The studied buildings are located in Montreal and are subjected to 15 simulated and historical ground motions scaled to match the uniform hazard spectrum. Herein, beams and columns were defined as nonlinear force-based beam column element with fiber section and Steel02 material. From analyses, the mean values of the following parameters: maximum interstorey drift, maximum drift angle and maximum beam rotation are computed.
The third part is designated to analyze the seismic response of MD-MRF structures equipped with friction-damped brace devices through numerical simulations of 4-, 8- and 12-storey building, using OpenSees. It is showed that the proposed hysteresis model for friction-damped brace responds well under dynamic loading and it is able to tune the response within the prescribed limits. Driving devices into bearing shows transitional changes consisted of decreasing damping and increasing stiffness. When this phase is encountered, the MD-MRF might respond as a back-up system and as a re-centering system. It is revealed that the three-phase hysteresis model of friction damper developed in this study must be calibrated against experimental test results conducted under cyclic loading until failure is reached. Due to lack of experimental test results several assumptions were made.


The growing demand for EO applications that work around the clock 24hr/7days a week, such as in border surveillance systems, emphasizes the need for a highly reliable cryocooler having increased operational availability and decreased integrated system Life Cycle (ILS) cost. In order to meet this need RICOR has developed a new rotary Stirling cryocooler, model K508N, intended to double the K508's operating MTTF achieving 20,000 operating MTTF hours. The K508N employs RICOR's latest mechanical design technologies such as optimized bearings and greases, bearings preloading, advanced seals, laser welded cold finger and robust design structure with increased natural frequency compared to the K508 model. The cooler enhanced MTTF was demonstrated by a Validation and Verification (V&V) plan comprising analytical means and a comparative accelerated life test between the standard K508 and the K508N models. Particularly, point estimate and confidence interval for the MTTF improvement factor where calculated periodically during and after the test. The (V&V) effort revealed that the K508N meets its MTTF design goal. The paper will focus on the technical and engineering aspects of the new design. In addition it will discuss the market needs and expectations, investigate the reliability data of the present reference K508 model; and report the accelerate life test data and the statistical analysis methodology as well as its underlying assumptions and results.


1. We explored patterns of co‐occurrence of ectoparasite species on individual hosts from Central Europe (Slovakia) and South America (Argentina) within and between higher taxa while controlling for confounding factors associated with variation between host individuals and host species, as well as spatial and temporal variation. We used a recently developed statistical approach, the hierarchical modelling of species communities.


The Global Strategy for Shelter to the Year 2000, adopted by the UN General Assembly in 1988, calls for a fundamental shift in governments' role in housing. Rather than attempting to provide housing directly, a policy that has usually failed, governments should play an enabling role. They should facilitate, energize, and support the activities of the private sector, both formal and informal, in housing development. This shift necessarily requires governments to obtain a broader overview of the housing sector as a whole and to better understand the mechanisms governing housing-sector performance. There is widespread recognition among governments that this requires better data and better, policy-oriented analysis of such data. There is thus a need for operational tools that measure sector performance and compare it across time and space. Such tools are necessary for seeing housing policy in a more global, Comparative perspective, whereby the accomplishments and lessons learned in one country can become more relevant to another. This comparative perspective may be invaluable for countries in several ways: in charting their paths; in formulating realistic development objectives; and in measuring their attainment, both over time and by comparison to other countries in similar circumstances. The Housing Indicators Program, formed with this shift in mind, was initiated jointly by the United Nations Centre for Human Settlements (Habitat) and the World Bank in October 1990. The general objective of the Housing Indicators Program is to develop conceptual, analytical, and institutional frameworks for managing the housing sector as a whole. More specifically, the Program has four alms: 1. to provide a comprehensive conceptual and analytical framework for monitoring the performance of the housing sector; 2. to create a set of practical tools for measuring the performance of the housing sector using quantitative, policy-sensitive indicators and to test these tools in a broad range of countries;


Abstract This article examines the development of Muslim businesses in the UK with particular reference to the northern city of Bradford in the context of Asian business development as a whole. Asian businesses in Bradford have grown rapidly since they first emerged in the late 1950s so that there were 1800 by 1990. In Britain as a whole, there are an estimated 61,000 Asian owned businesses. The article shows that Muslim owned businesses are more likely to concentrate on the ethnic market. They are smaller than the average small business in terms of turnover and employment and concentrated in areas of low profitability. Muslims are also more likely to enter into business because of unemployment than for entrepreneurial reasons and are under‐represented compared to their proportion of the Asian population. This is due to their relatively lower socio‐economic status which in part is determined by cultural factors, namely the low participation of Muslim women in the labour force. Hence, contrary to the preva...


Multiple-antenna backscatter is emerging as a promising approach to offer high communication performance for the data-intensive applications of ambient backscatter communications (AmBC). Although much has been understood about multiple- antenna backscatter in conventional backscatter communications (CoBC), existing analytical models cannot be directly applied to AmBC due to the structural differences in RF source and tag circuit designs. This paper takes the first step to fill the gap, by exploring the use of spatial modulation (SM) in AmBC whenever tags are equipped with multiple antennas. Specifically, we present a practical multiple-antenna backscatter design for AmBC that exempts tags from the inter-antenna synchronization and mutual coupling problems while ensuring high spectral efficiency and ultra-low power consumption. We obtain an optimal detector for the joint detection of both backscatter signal and source signal based on the maximum likelihood principle. We also design a two-step algorithm to derive bounds on the bit error rate (BER) of both signals. Simulation results validate the analysis and show that the proposed scheme can significantly improve the throughput compared with traditional systems.


Two-third of the population of Nepal depends on agriculture which shares about 31% of gross domestic product. Although there is huge potential of vegetable cultivation in Nepal, however post-harvest losses of vegetable negatively affect the economy of Nepalese agriculture. The vegetables are vulnerable to high temperature. The adoption of newer storage techniques is necessary to prevent waste of fresh vegetables. The zero energy cool chamber (ZECC) is an ecofriendly system with low cost of construction. The present study was conducted to qualify the quality and storability of vegetables (pointed gourd and okra) in different storage conditions such as in ZECC, room, and freeze conditions. We measured the physiological loss of water (PLW) and vitamin C of vegetables under different storage conditions. The study was conducted at Agricultural Engineering Division, Khumaltar, Lalitpur, Nepal. Pointed gourd and okra were purchased from the local market. They were stored in three different storages conditions such as in ZECC, room condition, and freeze conditions. The results showed that the highest PLW (%) was recorded on fifth days of storage for the room storage and the lowest was recorded for ZECC condition. The vitamin C significantly increased on the fifth day of storage compared to the first day for all types of storage. On the seventh day of storage, vitamin C was decreased compared to the fifth day in both ZECC and freeze conditions. The PLW was higher in freeze storage condition compared to that of ZECC condition. We concluded that pointed gourd and okra stored in ZECC can be stored until fifth day of storage after considering both quality and PLW. Our result suggested that ZECC can be used as a storage structure for vegetables such as pointed gourd and okra.


In this paper, the transient of the flow field of the nuclear main pump has been analyzed in the SBLOCA and the half mass flow rate time is obtained through the simulation. The results of the simulation show that, as nuclear main pump runs down, the mass flow rate and head of the pump drops as well. The blade surface pressure is not evenly distributed. The blade bears the force of the flow. So Pump unit should have sufficient moment of inertia, so that when the reactor in an emergency shuts down caused by the failure of power supply, nucleate burning down can be avoided by cooling the core. On the braking operation condition, the half mass flow rate time required should be guaranteed. Through simulation, we find when the half time is equal to 10s, the half mass flow rate time is about 4.6s Though it is a little shorter than 5s required, the AP1000 model selected basically meet the idle requirement.


In this work, we report two multifocal terahertz (THz) lenses (MTLs) based on reflective metasurfaces with focusing efficiencies of 57.3% and 46.3% at a frequency of 3.11 THz, respectively. The reflective metasurfaces were constructed by patterning the polarization-insensitive cross resonator array atop a continuous gold ground plane spaced by a layer of parylene film, which provides a complete 2π phase coverage. The elaborated phase profiles of the two MTLs were arranged based on the Fresnel-Kirchhoff diffraction theory. The two MTLs were theoretically and experimentally verified to converge continuous THz waves into two and four beam spots at their focal planes, respectively. Meanwhile, the MTLs were also experimentally demonstrated with multiple imaging abilities.In this work, we report two multifocal terahertz (THz) lenses (MTLs) based on reflective metasurfaces with focusing efficiencies of 57.3% and 46.3% at a frequency of 3.11 THz, respectively.

Ser was replaced at position 286 of firefly luciferase (Luciola mingrelica) by a series of naturally occurring and unnatural amino acids. The effect of these substitutions on the properties of luciferase, such as thermostability, pH dependence, and color of light emitted, was investigated. For these purposes, the Ser286 codon (AGT) was replaced by an amber stop codon (TAG) within the luciferase gene and transformed into Escherichia coli strains producing specific amber suppressor tRNA's to express luciferase with different substitutions at this position. The incorporation of Leu, Lys, Tyr, or Gln at this position reduced the thermostability of mutated luciferases. The color of emitted light changed upon substitution from yellow-green (λmax 582 nm) for the wild-type enzyme having Ser286 to, for example, red (λmax 622 nm) for luciferase having Leu286. For further evaluation of the structural relationship between the amino acid position at 286 and the wavelength of emitted light, we used the method of in vit...

An all-optically generated millimeter wave carrier at 21.67 GHz is experimentally achieved. This frequency is realized when two consecutively generated laser wavelength are heterodyned on the 60 GHz high-speed photodiode. The mixing between the Brillouin pump and the second-order Stokes wavelengths is spaced by 1.7 nm. This spacing, which is doubled from inherently generated Stokes shift, is accomplished through the isolated circulation of the first order Stokes wave in the double Brillouin Stokes shifter built with 25-km single mode fiber. The generated millimeter carrier is measured at 21.68 GHz, and its carrier phase noise and threshold power are −58.67 dBc/Hz and 19 mw of Brillouin pump power respectively.

Frame theory believes that meanings and cultural connotations of language exist in frames, and linguistic expressions are only symbols used to activate the frames.Therefore, the key to the translation of Chinese ancient poems into English is to seek the relevant English expressions that can activate the frames in the target language similar to those of the source language. Only in this way can the implicit meanings and connotations in the poems be understood by the target readers. Frame, the nature and strategies of the translation of Chinese ancient poems into English are the foci of the study herein.


CAPTCHAs exploit the gap in the ability between a human and a machine to understand the semantics of specific multimedia content, with vast applications in computer security. In this paper we compare two techniques in automated CAPTCHA solving for text-based CAPTCHA schemes, i.e., Classification based on the Vector Space Model (VSM) versus a popular Optical Character Recognition (OCR) engine. For each technique, we build a CAPTCHA solver and give it specific sets of text-based challenges to break. From our results we draw conclusions whether it is efficient to create a CAPTCHA solver by applying parts of the VSM theory and implementing a Vector Space Image Recognizer (VSIR).

OF THE DISCLOSURE A powdered refractory material is formed into a billet by compacting the powder and sintering the resulting compact. The sintered billet is placed in a hot pressing mold where it is surrounded with an intimate mixture of a first component selected from alkali and alkaline earth metal chlorides, fluorides and silicates and mixtures thereof and a finely divided second component selected from silica, alumina, zirconia, magnesia, calcium oxide, spinels, mullite, anhydrous alumino-silicates and mixtures thereof which are solid at the hot pressing temperature to be employed. The billet and surrounding mixture are then heated to a temperature at which the mixture is plas tic, and while maintaining that temperature, pressure is applied to the mixture, thereby isostatically hot press ing the billet. A sufficient quantity of the first compo nent must be present so that the mixture becomes plastic at the hot pressing temperature. The mixture will ordi narily contain from 5% to 40% by weight of the first component and from 60% to 95% of the second compo ment. Hot pressing temperatures of from 1,000 to 2,000 C. and pressures of from 400 to 6,000 p.s. i. are repre sentative. BACKGROUND OF THE INVENTION This invention relates to the production of high den sity refractory bodies. Such refractory bodies possess superior hardness, toughness, strength, wear-resistance and chemical resistance and exhibit superior performance as cutting edges for machining high strength alloys, drill ing rocks, cutting or shaping other hard materials, as high-temperature fixtures or structural materials and as wear, abrasion and chemical resistant parts, particularly at high temperatures, for example, in certain chemical

Supervisory Committee Dr. Stephanie Willerth (Department of Mechanical Engineering and Division of Medical Sciences) Supervisor Dr. Martin Byung-Guk Jun (Department of Mechanical Engineering) Departmental Member Dr. Bob Chow (Department of Biology) Ouside Member Dr. Alex Brolo (Department of Chemistry) Outside Member Electrospun biomaterial scaffolds can be engineered to support the neural differentiation of induced pluripotent stem cells. As electrospinning produces scaffolds consisting of nano or microfibers, these topographical features can be used as cues to direct stem cell differentiation. These nano and microscale scaffolds can also be used to deliver chemical cues, such as small molecules and growth factors, to direct the differentiation of induced pluripotent stem cells into neural phenotypes. Induced pluripotent stem cells can become any cell type found in the body, making them a powerful tool for engineering tissues. Therefore, a combination of an engineered biomaterial scaffold with induced pluripotent stem cells is a promising approach for neural tissue engineering applications. As detailed in this thesis, electrospun scaffolds support the neuronal differentiation of induced pluripotent stem cells through delivering the appropriate chemical cues and also presenting physical cues, specifically topography to enhance neuronal regeneration. This thesis seeks to evaluate the following topics: multifunctional electrospun scaffolds for promoting neuronal differentiation of induced pluripotent stem cells, neuronal differentiation of human induced pluripotent stem cells seeded on electrospun scaffolds with varied topographies, and controlled release of glial cell-derived neurotrophic factor from random and aligned electrospun nanofibers.
