The Mycetophagidae (Coleoptera) of the Maritime Provinces of Canada

many records from the southern mainland of Nova Scotia, Cape Breton Island, and Prince Edward Island (Fig. 1). Records from New Brunswick and the northern main- land of Nova Scotia are lacking, but it is probable that it is found throughout the region. In the Maritime Provinces L. tetraspilotus has been collected in many habitats including coniferous, deciduous, and mixed forests, seashores, coastal barrens, grass- lands, marshy areas, a sandy pine barren, and an old i eld ecosystem. Specimens have been collected on the foliage of white pine (Pinus strobus L.), jack pine (Pinus sylvestris L.), red spruce (Picea rubens Sarg.), balsam i r (Abies balsamea (L.) Mill.), on decidu- ous, and herbaceous vegetation, on bristly sarsaparilla (Aralia hispida Vent.), and in a rotting mushroom. Klimaszewski and Majka (2007) reported L. tetraspilotus as an in- quline inhabitant of oak apple galls on red oak (Quercus rubra L.) induced by Andricus (Callirhytis) sp. (Cynipidae) wasps. Rauf et al. (1985) found it on jack pine, Tucker (1919) found it on American mistletoe (Phoradendron l avescens (Pursh) Nutt., and Ulyschen and Hanula (2010) reared it from decomposing loblolly pine (Pinus taeda L.) logs in South Carolina.

Adventive Staphylinidae (Coleoptera) of the Maritime Provinces of Canada: further contributions

Adventive Staphylinidae (Coleoptera) of the Maritime Provinces of Canada: further contributions

Seven species of adventive Palaearctic staphylinids, Ilyobates bennetti Donisthorpe, Meotica exilis (Kn- och), Meotica “pallens” (Redtenbacher), Anotylus insecatus (Gravenhorst), Anotylus tetracarinatus Block, Oxytelus sculptus Gravenhorst, and Lathrobium fulvipenne (Gravenhorst) are newly recorded in the Maritime Provinces of Canada. One of these, M. exilis, a cosmopolitan species, is newly recorded in Canada and represents the fi rst verifi able report of this species from North America. h e history of M. exilis in North America is examined indicating that previous reports were the result of misidentifi ca- tion or of specimens of uncertain identity that can no longer be located. h e confused nomenclature of this species is also discussed. h e confused taxonomy of Meotica “pallens” is discussed with regard to the identity of the species reported under this name in North America. Atheta dadopora h omson is newly recorded in Prince Edward Island. Records are provided that establish the presence of L. ful- vipenne in North America in fi ve Canadian provinces. Observations on A. insecatus in the fi eld have established that they are predators of dipteran larvae. New early dates of detection are reported for Quedius curtipennis Bernhauer, Tasgius ater (Gravenhorst), Philonthus cognatus Stephens, and Philonthus rectangulus Sharp. As a consequence, 87 species of adventive Staphylinidae are now known to occur in the Maritime Provinces, 76 of which have been recorded in Nova Scotia, 61 in New Brunswick, and 29 on Prince Edward Island. h e staphylinid fauna is briefl y discussed in relation to its zoogeographic components and its regional composition.

Contributions to the knowledge of the Aleocharinae (Coleoptera, Staphylinidae) in the Maritime Provinces of Canada

Contributions to the knowledge of the Aleocharinae (Coleoptera, Staphylinidae) in the Maritime Provinces of Canada

Placusa canadensis is newly recorded in the Maritime Provinces. In Canada it has been previously recorded in Ontario and Québec; in the United States it is known from Ohio and West Virginia (Klimaszewski et al. 2001). In Québec this species has been found predominantly in sugar maple (Acer saccharum Marsh.) stands, occasion- ally in white spruce (Picea glauca (Moench) Voss) forests. h ey have been collected from under the bark of recently fallen trees and from rotting fungi and tree stumps (Klimaszewski et al. 2001). h e specimens in Nova Scotia were found in association with specimens of Carpophilus sayi Parsons [Nitidulidae] (abundant), and Corticeus tenuis (LeConte) [Tenebrionidae] (infrequent) in the same subcortical habitat.

Buying Behavior Of Organic Vegetables Product The Effects Of Perceptions Of Quality And Risk

Buying Behavior Of Organic Vegetables Product The Effects Of Perceptions Of Quality And Risk

describe and understanding the evaluated of customer and customer behavior (Tuu & Olsen, 2011:29). Consumer behavior involves risk in the sense that any action of a consumer will produce consequences which he cannot anticipate with anything approximating certainty, and some of which at least are likely to be unpleasant (Bauer, 1960) and sacrifice to obtain a product (Zeithaml, 1988). Value of risk often in empirical study on customer behavior in foods (Knight et al., 2007:794), considering food is basic needs of customer every day. Perceived risk is not only related to consumers’ information acquisition and processing activity but to post- decision processes as well, where people will seek out information that confirms the wisdom of their decision (Horvat & Dosen, 2013:273). Consumer risk perception and its impacts on purchasing behavior are a critical component of the management of food safety (Yeung et al., 2010:306), perceived risk can be explained as consumers’ doubt on the results of their buying decisions (Arslan et al., 2013). It can be interpreted that perception of risk is sacrificed value of customer when buying products as result from selection until interpretation from alternative product. Described of organic product can be measure with financial risk, performance risk, physical risk and social risk (Yee et al., 2011:54). Research on the same years is delivered of measure of risk, especially food include health risk, performance risk, psychosocial risk, and financial risk (Tuu et al., 2011:368). Perception of risk have negative relationship with perception of quality (Kim & Lennon, 2013:33), and on last research found that perception of quality have negative relationship with perception of risk received by customer (Chen & Chang, 2005:521). Based on theoretical study which has been discussed, next determined research hypothesis.

Influence Of Industry Environment Adaptation To The Improved Performance Of Islamic Financial Institutions

Influence Of Industry Environment Adaptation To The Improved Performance Of Islamic Financial Institutions

companies of any kind, including the banking industry is not enough to just rely on internal resources and capabilities they have and implement business functions are single fighter. The success gained competitive advantage depends on the ability of companies in perceived value to customers who exceed that offered by competitors. For an industry that includes the banking industry in the creation of value to the customer and achieving superior performance must be able to anticipate and adapt to changes in the type and intensity of competitive forces in the industrial environment. Increasing the strength of competition in the industrial environment both of Rivalry Among Existing sellers and new entrants will result in price competition and tighter margins obtained which will ultimately affect the performance of the company. Especially against the banking industry, including Islamic banking, competitive landscape facing now not only fellow Islamic banking in the country, but because the growth is very promising, also has attracted foreign banks to plunge also in the Islamic banking industry both full-pledged islamic banking and foreign commercial banks which have business units islamic window. Influential forces affecting the competitive environment on the performance of Islamic banking in particular through the introduction of new entrants of foreign banks into Islamic banking industry is evidenced by the results of research conducted by Hassan et. al. 2013). The results of research by using econometric models and using 14 samples from 24 countries who have foreign Islamic banks and Islamic banks with domestic observation period financial statements (financial statements) of the 149 Islamic banks domestic and foreign Islamic banks during 1996 to 2010 concluded that: In general, foreign Islamic banks as new competitors enjoy more Linggi performance in the form of net profit margin in 7 countries of the 24 countries sampled, but instead get the net profit margin is very low in 5 other countries. Another finding is the rate of returns (in the form of ROE and ROA) plays an important role in the decisions of foreign Islamic banks to entry into the market of Islamic banking in the country, macroeconomic conditions only act as a supporting role, considered tax policy plays a role in the decision-hostile entry decision and the presence of foreign Islamic banks, the financial crisis did not significantly affect the entry decision. Meanwhile, the analysis of the influence of foreign Islamic bank entry on the performance of the domestic Islamic banks, among others, show the profitability of the domestic Islamic

Analytical Determining Of The Steinmetz Equivalent Diagram Elements Of Single-Phase Transformer

Analytical Determining Of The Steinmetz Equivalent Diagram Elements Of Single-Phase Transformer

This model, preached by any teacher of electrical engineering to his students on the various levels, was given like postulate. This article proposes an analytical justification to the equivalent diagram elements of single-phase transformer current, particularly to those of the central branch. The article is organized in three main sections. Section II begins by the calculation of active power consumed in a parallelepiped electromagnetic domain subjected to a variable flow. The result is applied to a shell form single-phase transformer. With open load test, the power consumption linked to the leakage inductance and resistance of the transformer winding is neglected in front of the consumption of the central branch [11]. But it is not the case for a loaded transformer. The methods to determine resistances of the reels are indisputable. This article gives the expressions of the elements of the central branch in the model of Steinmetz starting from the powers and their site. It studies also the variation relation of the iron resistance and the iron reactance compared to the computed values with 220 V. Section 2 is dedicated to this calculation. Discussions and a comparison of results are described in Section 3. The final section is devoted to the article conclusion.

Modeling of Two-Stage Solidification: Part II Computational Verification of the Model

Modeling of Two-Stage Solidification: Part II Computational Verification of the Model

In the work we assume that the first stage of solidification is the same for both modified and unmodified alloys. Thus, the same dendritic nucleation density is used in both cases. However, we should keep in mind that modifier may affect the dendritic structure formation. In the second stage of the solidification, the nucleation process unfolds in slightly different way, depending on the eutectic transformation mode. In such case nucleation phenomena depends on different densities and different algorithms, as explained in Part I. The authors of the series of papers [3, 6, 7] investigated solidification of modified and unmodified hypoeutectic alloys, and indicated that the difference in nucleation densities for eutectic structure must exists. In [6] McDonald et al. claim that the difference in nucleation density and the size of eutectic grains is “drastic”. It should be noted, that due to the fact that eutectic transformation modes are relatively new area of research, only limited experimental data is available. Keeping this in mind, in our approach we assumed that in the case of modified alloys the nucleation density for eutectic structure is the same as for the dendritic structure. In turn, for the second

Influence of tungsten and titanium on the structure of chromium cast iron

Influence of tungsten and titanium on the structure of chromium cast iron

Studies have proved that structure of the chromium cast iron greatly depends on the additionally introduced elements such as titanium and tungsten. Titanium is a carbide-forming element, but in contrast to other elements of this type it does not form complex carbides in the chromium cast iron, but only a TiC carbide, which is formed at high temperature in the liquid metal. Tungsten is also a carbide-forming (and pearlite-forming) element but, like titanium, is rarely used in the manufacture of chromium cast iron. High melting points of tungsten and titanium may cause difficulties in the metallurgical process of chromium cast iron manufacture. Tungsten effect on the mechanical properties is similar to that of molybdenum, although it is weaker. Tungsten increases the hardenability of cast iron. Currently, the use of tungsten can be justified because of its price slightly lower than that of molybdenum.

Prostate Cancer: A State of The Heart

Prostate Cancer: A State of The Heart

Surgical castration, oestrogens, LHRH agonists and GnRH antagonists, anti-androgens, combined androgen blockade (CAB), and 17,20-lyase inhibitors are some of the treatment options available to a patient with CV risk factors and known metastatic disease. Due to the high rate of thromboembolic events with oral oestrogen, it has somewhat been abandoned as a therapy. The oestrogen patch, however, is not thought to induce thromboembolic events. Prof Klotz described a study comparing a LHRH agonist and a transdermal oestrogen patch in which the use of the patch did not increase the number of CV events versus the LHRH agonist, suggesting that this may be regarded as a potential therapeutic option. 3 LHRH agonists have

The Effects of Gender Segregation at the Occupation, Industry, Establishment, and Job-Cell Levels on the Male-Female Wage Gap

The Effects of Gender Segregation at the Occupation, Industry, Establishment, and Job-Cell Levels on the Male-Female Wage Gap

in four dimensions: occupation, industry, firm, and job cell. One of the contributions of this paper is the estimation of these effects including fixed effects to control for unobserved, time-invariant characteristics of workers, firms, and worker-firm matches. The workers’ fixed effects capture unobserved heterogeneity in their abilities/skills, motivation, preferences, and personality traits, all of which affect wages and can be correlated with the allocation of workers across the four dimensions of interest. If females’ tastes are such that they are prepared to trade more easily the pecuniary for non-pecuniary aspects of the jobs, one should expect to observe a higher concentration of women in occupations, industries, establishment, and job cells that pay lower wages. It could also be that less productively able men and women sort (or are sorted) into predominantly female jobs that command lower wages. In both cases, the estimates of the effects of female segregation on wages will be misleading if worker-specific fixed effects are not part of the model.

General Considerations about Matrimonial Regime under the Provisions of the New Romanian Civil Code

General Considerations about Matrimonial Regime under the Provisions of the New Romanian Civil Code

In the past 50 years Romanian experts have equated the notion of property relations between spouses with the notion of matrimonial regime. The Romanian contemporary doctrine regarding the notions of matrimonial regimes and property relations between spouses is more nuanced than in the past, claiming that the two notions are closely linked, but not identical. Thus, the matrimonial regime should designate a system of legal rules that govern the property consequences of marriage, but not of any consequences (there are some pecuniary reports that are not of interest for the matrimonial regimes for example the obligation of maintenance between spouses, as well as those have in relation to other people: children, relatives, etc.). Consequence: matrimonial regime is part of the rules that systematize the "patrimonial relations between spouses”, relationships which are the subject matter of more disciplines: property right of the family, inheritance law etc.. . As such, the concept of matrimonial regime may be perceived in a narrow sense, as it may also have wider significance. In a narrow sense –the sense preferred by the author - the matrimonial regime is a set of legal rules governing the relations between spouses regarding the pecuniary rights and obligations of conjugal life and the relations concerning their management . In a wider sense, the matrimonial regimes (Vasilescu, 2003) also refer to the pecuniary relations between spouses and third parties, whether they are people completely foreign from marriage or people with specific legal ties to it (Vasilescu, 2003).

Investigating The Use Of Mobile Computing In Zimbabwe Polytechnics Case Of A Polytechnic In Zimbabwe

Investigating The Use Of Mobile Computing In Zimbabwe Polytechnics Case Of A Polytechnic In Zimbabwe

ABSTRACT: Mobile computing has become an invaluable and inevitable part of teaching and learning in educational institutions globally. Zimbabwean polytechnics are not spared and those institutions that have chosen to integrate mobile computing with existing teaching and learning applications stand to benefit more than their slow and stagnant counterparts. This paper is investigated whether mobile computing is being used in Zimbabwe Polytechnics. It is based mainly on primary research since no particular research has targeted Polytechnics in Zimbabwe and specifically the Polytechnic understudy in this area, thus a survey was conducted and the survey results were used as the main data source. However, secondary research was incorporated to see what other researchers have found in similar topics the world over. This paper identifies the mobile computing hardware technology, software and communication technologies used at the Polytechnic. It then outlines the achievements made in this area and the associated benefits of such achievements. Finally highlights the challenges currently being faced by the polytechnic in implementing mobile computing and the opportunities the institution can exploit by fully utilizing the technology. The main findings of this research were that Zimbabwe polytechnics in general and the polytechnic in particular have adopted usage of mobile computing to enhance their teaching and learning and administrative activities. There are visible and tangible achievements and benefits that have been realized. Opportunities have been identified which the polytechnic can exploit if it fully embraces mobile computing. However there are some challenges hindering the progress in this regard.

White and gray solidification of the Fe-C eutectic

White and gray solidification of the Fe-C eutectic

This means that branching of graphite, which is needed for growth at the optimum-lamellar spacing, is difficult. The lamella of graphite will then grow straight in a converging or diverging way, leading to a whole range of lamellar spacing (corresponding to a range of undercooling given by eq. (1)). It has been shown that growth cannot be achieved with a spacing lower than the extreme one. Growth of converging lamella will then stop when this spacing is reached. At the opposite, growth of diverging lamella will be stable only as long as is less than a critical spacing br where branching occurs, as shown in fig. 3.

Winning the Oil Lottery: The Impact of Natural Resource Extraction on Growth Tiago Cavalcanti Daniel Da Mata Frederik Toscani

Winning the Oil Lottery: The Impact of Natural Resource Extraction on Growth Tiago Cavalcanti Daniel Da Mata Frederik Toscani

Enhanced recovery is so important in the petroleum industry that the location of the producer well is chosen with the secondary well (injection well) in mind. As mentioned before, efforts to enhance recovery are costly and are dependent upon the state of the economy and the potential oil recovery volume. Consequently, repeated monitoring of a reservoir is essential to choose the best locations for the injection wells. The idea is to design an optimal distribution of injection wells so as to optimize long-term production. There are several types of wells: wildcat well, rank wildcat well, step-out well, pro- ducer well, injection well, etc. Since there are different steps in the process of obtaining oil, wells are classified broadly as exploratory wells and development wells. Examples of exploratory wells are wildcat wells (drilled a mile or more from an area of existing oil production) and rank wildcat wells (drilled in an area where there is no existing produc- tion). If the exploratory drilling proves successful, the company starts to drill step-out wells (also included in the exploratory well category). After the oil field has been delin- eated, the company starts to drill production wells within the known extent of the field. Every well drilled inside the known extent of the field is called a development well (Hyne (2001)). The development well category includes producer wells and injection wells (re- call that injection wells are drilled to enhance oil recovery). Different categories of wells have different probabilities of finding oil. On average, rank wildcat exploratory wells have lower success ratio than step-out wells. An oil company can rank wells in terms of probability, even in the face of uncertainty. The American Petroleum Institute reported that in 2000 the success rate for wildcat wells was 39% (Hyne (2001)). Note that an unsuccessful drilling is classified as a dry hole in both exploratory and development well categories.

Evaluation of susceptibility of the ZRE1 alloy to hot cracking in conditions of forced strain

Evaluation of susceptibility of the ZRE1 alloy to hot cracking in conditions of forced strain

The nil strength temperature (NST) for the alloy was determined by testing cylindrical Ø 6 x 90 mm specimens on the Gleeble 3800 simulator. S-type thermocouples were pressure welded to the specimens, and then the specimens were fixed in the chamber by means of copper holders. Constant distance of 52.4 mm was kept between the holders. After evacuation of air, the chamber was filled with argon (to 0.14 hPa). Then, the 0.6 – 0.7 kN minimum pre-load was applied and was maintained until the end of experiment. The specimens were heated at the 20 o C/s rate to 400 o C, and then at the 1 o C/s rate. The NST was determined as the temperature at which the specimen lost its cohesion. The NST for the ZRE1 alloy in as-delivered state is 535 o C.
