Actions of compact abelian groups on semifinite injective factors

The Clifford algebra construction allows one to associate with any unitary representation of a group an action of the group on an algebra in a functorial way. If the representation is infinite dimensional one must allow infinite dimensional algebras and one is led immediately to consider actions of groups on factors not of type I. Using this approach, Blattner showed in [1] that any separable locally compact group has a faithful action, by outer automorphisms and the identity, on the hyperfinite type II~ factor ~. It was certainly not obvious at the time that one might hope to say much more about the actions even of finite cyclic groups on ~ , but largely thanks to work of Connes, much progress has been made. This paper adds another step in a continuing project by giving a detailed description of all actions of a compact abelian group on semifinite injective factors. The most general results on actions of abelian groups on von Neumann algebras appear in [10], where Connes and the second author established the relationship between their discrete and continuous decompositions of type III von Neumann algebras using the flow of weights, itself an action of R on an abelian von Neumann algebra. The results of [10], powerful as they are, give precious little information on the
Drought-Induced Reductions and Limited Recovery in the Radial Growth, Transpiration, and Canopy Stomatal Conductance of Mongolian Scots Pine (Pinus sylvestris var. mongolica Litv): A Five-Year Observation

Determining plant–water relationships in response to drought events can provide important information about the adaptation of trees to climate change. The Mongolian Scots pine (Pinus sylvestris var. mongolica Litv), as one of the major tree species to control soil loss and desertification in northern China, has experienced severe degradation in recent decades. Here, we aimed to examine the impacts of a two-year consecutive drought and another year of drought on the radial growth, transpiration, and canopy stomatal conductance of Mongolian Scots pine over a five-year period, especially in terms of its recovery after drought. The study period during 2013–2017 consisted of a ‘normal’ year, a ‘dry year’, a ‘very dry’ year, a ‘wet’ year, and a ‘dry’ year, according to annual precipitation and soil moisture conditions. Based on measurements of the sap flow and diameters at breast height of 11 sample trees as well as the concurrent environmental factors, we quantified the reductions in tree radial growth, transpiration, and canopy stomatal conductance during the drought development as well as their recovery after the drought. The results showed that the tree radial growth, transpiration, and canopy stomatal conductance of Mongolian Scots pines decreased by 33.8%, 51.9%, and 51.5%, respectively, due to the two consecutive years of drought. Moreover, these reductions did not fully recover after the two-year drought was relieved. The minimum difference of these parameters between before and after the two-year consecutive drought period was 8.5% in tree radial growth, 45.1% in transpiration levels, and 42.4% in canopy stomatal conductance. We concluded that the two consecutive years of drought resulted in not only large reductions in tree radial growth and water use, but also their lagged and limited recoveries after drought. The study also highlighted the limited resilience of Mongolian Scots pine trees to prolonged drought in semi-arid sandy environmental conditions.
REACTIVE SINTERING OF ZIRCONIUM CARBIDE BASED SYSTEMS

The high cost of commercial ZrC nanopowder has spurred the development of cost-efficient and low-energy approaches for carbide synthesis. Mechanical activation synthesis (MAS) by high-energy ball milling technology and reactive vacuum sintering was used to synthesize ZrC powder from zirconia (ZrO2) at the low temperature of 1500°C. However, a major drawback for structural ZrC powder made from MAS was the relatively low fracture toughness, and difficulty ensuring adequate hardness and densification when vacuum sintered below 2000°C. ZrC combined with 20% weight molybdenum was sufficient to yield a cermet of 96.1% densification, hardness of 17GPa, and fracture toughness of 5.236. 08MPa*m. This present study was able to achieve a genuinely homogenous ZrC-Mo cermet in vacuum sintering temperatures not exceeding 1900°C.
Effects of Micro-Financing on Growth of Small and Micro Enterprises in Mombasa County

: Majority of small and micro enterprises in Kenya are mostly out of scope of formal banking services. They depend on MFIs loans to finance their business operations. The fundamental objective of this study was to assess the effects of Micro financing on growth of small and micro enterprises in Mombasa County. Despite access to credit SMEs growth remains a major problem. Access to credit should enable a business to achieve their growth objective. Despite this it is interesting to note that most of the SMEs could not survive third year of incubation period. Descriptive Survey method was employed in this study. The study adopted stratified and systematic random sampling method. The sample size was 157 SMEs. Semi-structured questionnaire was designed to facilitate the acquisition of data. Data was collected from 102 respondents, a response rate of sixty five percent. Sales, income and competitiveness were used as the independent variable while growth of SMEs as dependant variable. Descriptive statistics was used to analyze data. Results indicated that microfinance has positive effects on growth of SMEs. Majority of the owners indicated that microfinance has enabled them to expand businesses, build their business assets. Also ability of the business to complete was enhanced.
Business Model Development: A Customer-Oriented Perspective

Purpose: This study provides a business model development framework that explicitly focuses on the customer as well as integrating customer knowledge into the development process for enhanced value creation. The proposed framework shall enhance our understanding about this phenomenon and present a helpful guidance for researchers and practitioners. Design/Methodology/Approach: The study follows a conceptual approach that is based on insights from prevailing literature. The deduced findings are illustrated with supplementary context from a prominent case study. Findings: The findings underline the importance of customer-orientation for successful business model development. Furthermore, business model development should follow an actively managed, systematic approach that takes into account distinctive customer groups, business model change intensity, and business model development types. The presented framework provides fruitful avenues for future research and valuable guidance for management. Practical Implications: The presented framework provides managers with a tool to plan and organize their business model development process. Research limitations: Given the vast amount of academic journals, it is unlikely that every applicable scientific publication is included in the analysis. The illustrative example is descriptive in nature, and thus, does not possess empirical validity. Originality/Value: The main contribution of the study is the explicit transfer of important aspects of the market orientation literature to the business model development phenomena and the strict integration of the customer into the associated process. Thus, this study provides a customer-oriented framework on business model development that supports the field’s conceptual progress. Furthermore, the study supports the normative debate in the business model literature. Please cite this paper as: Wirtz, B.W. and Daiser, P.

Evolutionary aspects on the origin, distribution and ramifications of the ischiadicus nerve in the giant anteater (Myrmecophaga tridactyla)

This work aimed to describe the origin, distribution, and ramifications of the ischiadicus nerve in the giant anteater and to provide anatomical data which could explain not only the evolutionary aspects but also provide important information for other related works. For the present study, four specimens were used, prepared by perfusion of 10% formaldehyde solution via the femoral artery, for conservation and dissection. The origin of the right and left ischiadicus nerves in the giant anteater from the ventral ramification of the third lumbar (L3) and the first (S1), second (S2), and third (S3) sacral spinal nerves. These nerves were symmetrical in all animals studied. The distribution and ramification occurred to the superficial, middle, and deep gluteal, gemelli, piriform, quadratus femoris, tensor fasciae latae, caudal crural abductor, cranial and caudal parts of the biceps femoris, adductor, semitendinous, and cranial and caudal parts of the semimembranous muscles. Based on the origins of the ischiadicus nerves, there is a caudal migration in the nerve location in animals in a more recent position on the evolutionary scale due to reconfiguration of the lumbosacral plexus, resulting from the increase in a number of lumbar vertebrae. There is no complete homology of the muscle innervation.
Optimal Redistributive Policy in Debt Constrained Economies

This paper studies optimal taxation, as a redistributive policy, in an open economy facing long-run binding debt constraints and inequality. The debt constraints arise endogenously from the government’s limited commitment, and become relevant in the long run due to the impatience of domestic agents. The limited borrowing distorts the intratemporal substitution between consumption and leisure, induces under-accumulation of capital, and discourages domestic borrowing. The redistribution concern affects the tax levels via the trade-off between equity and efficiency, and the tax dynamics via tightening/relaxing the debt constraints. The optimal labor tax is constant with unconstrained borrowing, but eventually converges to a real limit that depends on inequality and distributional preference. The efficient contract features front-loading redistribution and back-loading efficiency, allowing the economy to accumulate a large external debt position, and increase its borrowing capacity when the debt constraints bind.
Application of Tryptophan as Supplementary Nutrient on Dehydrogenase Activities and Economic Parameters in Bombyx Mori L

The important growth regulating factor in silkworm or in any organism is nutrition. Dietary nutrients not only determine growth and development of silkworm larvae but also cocoon yield. An attempt has been made in the present investigation to record the influence of mulberry leaf supplemented with tryptophan at varied concentrations viz., 0.5, 1.0 and 1.5 % on succinate dehydrogenase (SDH) and lactate dehydrogenase (LDH) activities as well as economic parameters in bivoltine double hybrids FC1 x FC2 and FC2 x FC1. The study revealed that both the hybrids recorded highest enzyme activities at 1.5 % concentration of tryptophan supplementation over remaining concentrations and elevated the cocoon weight, shell weight, shell percentage, filament length, filament weight, denier and renditta.
Native and Invasive Small Mammals in Urban Habitats along the Commercial Axis Connecting Benin and Niger, West Africa

Based on compiled small mammal trapping data collected over 12 years from Benin and Niger (3701 individual records from 66 sampling sites), located in mainland Africa, we here describe the small mammal community assemblage in urban habitats along the commercial axis connecting the two countries, from the seaport of Cotonou to the Sahelian hinterland, with a particular focus on invasive species. In doing so, we document extant species distributions, which highlight the risks of continuing the range expansion of three synanthropic invasive rodent species, namely black rats (Rattus rattus), brown rats (R. norvegicus), and house mice (Mus musculus). Using various diversity estimates and community ecology approaches, we detect a latitudinal gradient of species richness that significantly decreased Northward. We show that shrews (Crocidura) represent a very important component of micro-mammal fauna in West African towns and villages, especially at lower latitudes. We also demonstrate that invasive and native synanthropic rodents do not distribute randomly in West Africa, which suggests that invasive species dynamics and history differ markedly, and that they involve gradual, as well as human-mediated, long distance dispersal. Patterns of segregation are also observed between native Mastomys natalensis and invasive rats R. rattus and R. norvegicus, suggesting potential native-to-invasive species turn over. Consequences of such processes, especially in terms of public health, are discussed.
An NLO+PS generator for t ¯ t and W t production and decay including non-resonant and interference effects

We present a Monte Carlo generator that implements signiﬁcant theoretical improvements in the simulation of top-quark pair production and decay at the LHC. Spin correlations and off-shell effects in top-decay chains are described in terms of exact matrix elements for pp → (cid:2) + ν (cid:2) l − ¯ ν l b ¯ b at order α 4 α 2 S plus full NLO QCD corrections, where the leptons (cid:2) and l belong to different families, and b quarks are massive. Thus, the contributions from t ¯ t and Wt single-top production, plus contributions without top resonances and all relevant quantum interferences between different channels are fully included. Matrix elements are matched to the Pythia8 parton shower using a recently proposed method that allows for a consistent treatment of resonances in the POWHEG framework. These theoretical improvements are especially important for the interpretation of precision measurements of the top-quark mass, for single-top analyses in the Wt channel, and for t ¯ t and Wt backgrounds in the presence of jet vetoes or cuts that enhance off-shell effects. The new generator is based on a process-independent interface of the OpenLoops amplitude generator with the POWHEG-BOX framework.
ASSESSMENT OF ONLINE RESOURCES USAGE BY AGRICULTURAL SCIENCE LECTURERS OF TERTIARY INSTITUTIONS IN BENUE STATE, NIGERIA

The rapid growth of online resources (also called, digital resources, internet resources, electronic information sources or e‐library resources) provide new opportunities for teaching and learning practices in higher education, the world over. This study assessed online resources usage by agricultural science lecturers of tertiary institutions in Benue state, Nigeria. Data were collected from 193 lecturers randomly selected from six tertiary institutions and analyzed using percentages, mean scores, regression analysis and analysis of variance (ANOVA). The study revealed the types of online resources frequently used by respondents included electronic journals, electronic books, search engines abstracts, video/picture or graphic files and encyclopedia. Socio‐economic and institutional factors that significantly influenced the use of online resources included age (t= ‐2.287; p = 0.05) and number of years spent on formal education (t =2.022; P =0.05). The post‐hoc comparison using Tukey HSD test shows that there is a significant difference in the level of online resources usage among staff of different tertiary institutions as the mean score for University (M = 1.77, SD = 0.69) was significantly different from that of College of Agriculture (M = 0.79, SD = 0.64) and College of Education (M = 1.11, SD = 0.59). However, the mean score of College of Agriculture did not differ significantly from College of Education. Major constraints experienced by the lecturers in the use of online resources include high cost of access to online resources, non ‐ subscription for relevant online resources by institutions and connectivity problems. This study points to the need for institutional subscription to such online resources as AGORA, OARE and HINARI by management of these institutions to enhance academic teaching and learning in Nigerian tertiary institutions.
Capture and Competition: The Role of Product Market Competition in Reallocating Rents from Regulatory Capture*

The lobbying literature provides evidence of firms shaping their regulatory context, consistent with corporate rent-seeking. We propose that such rent-seeking, where it exists, is unlikely to enrich shareholders at the expense of customers when firms operate in competitive product markets. We test this proposition through an assessment of the dissipation of the cash benefits accrued from corporate tax inversions. We find lower accounting and stock-market returns to shareholders of inverting firms in competitive industries (relative to those in concentrated industries). Further, inverting firms in competitive industries are more likely to improve liquidity and invest in R&D relative to those in concentrated industries. The evidence suggests that in competitive industries lobbying “rents” accrue to customers over shareholders.
Sustainable Development Research on the Spatial Differences in the Elderly Suitability of Shanghai Urban Parks

As an important subset of the urban population and a major contributor to urban social wealth, the elderly play an important role in a city’s sustainable development. Based on data from the statistical yearbook and an empirical investigation, this paper evaluated the elderly suitability of 75 parks in China’s Shanghai Central District using a self-defined Python script tool based on ArcGIS. According to spatial differences in the elderly suitability of parks, we employed spatial interpolation to explore the reasons for variations in park services in different residential spaces in Shanghai Central District. The results revealed the following: (1) the elderly suitability of parks in Shanghai Central District decreases gradually from the inner ring to the outer ring; (2) the park accessibility in Shanghai Central District is generally low, and the park service space can be divided into five categories ranging from “low accessibility, super-low elderly suitability” to “high accessibility, high elderly suitability”; and (3) the advantages of regional function and location, the development of regional culture and tourism economy, and the implementation of regional elderly-care policies are factors promoting the improvement of the elderly suitability of regional park services. Finally, this paper provided scientific decision-making suggestions for Shanghai and other aging cities to optimize the elderly suitability of urban parks.
Comparison of total phenol content and antioxidant activity of herbal infusions with added Stevia reabaudiana Bertoni

An infusion is a beverage obtained from parts (dry leaves, flowers and fruits) of the shoot of several herbs or aromatic plants. Worldwide, most of the infusions are prepared from two types of manufactured teasI: black and green teas (Konieczynski et al., 2017), which are obtained from Camellia sinensis leaves, as are white and red teas. However, the growing season, geographic region and methods of fermentation create much variation in the composition and characteristics of the tea (Zhao et al., 2011) in addition to the variation associated with different stages of maturity of the leaves (Kosińska & Andlauer, 2014). Based on the method of fermentation, teas have been classified as non-fermented (white and green tea), semi-fermented (red tea) and fermented (black tea) (Camargo et al., 2016). Today, consumption of infusions has increased because of their beneficial properties, which are attributed to the presence of phenolic compounds (Cleverdon et al., 2018). These compounds have higher antioxidant capacity than fruits and vegetables and are even more potent than vitamin C, E and carotenoids (Wiseman et al., 1997). Because of these characteristics, teas are often used as remedies to cure diverse organic disorders. On this respect, Hernández-Saavedra et al. (2013) report that herbal infusions can help reduce obesity, insulin intolerance and systemic inflammation. On addition, dehydrated stevia leaves can be added to infusions to improve their characteristics (Shevchenko et al., 2013). Because stevia has therapeutic values such as antioxidant, antimicrobials, antidiabetics, antihypertensive, cardiotonic; also; it has stevioside and rebaudioside, which give it an intense sweet flavor; it is good source of protein, crude fibre, minerals and amino acids (Joseph & George, 2019; Ahmed & Mukta, 2017). Processed stevia is up to 200-300 times sweeter than sucrose (Ghaheri et al., 2018), it is considered the best sugar substitute (Joseph & George, 2019). Although stevia extracts are being used only as sweeteners, aqueous extract of the dehydrated leaves have numerous functional properties (Ahmed & Mukta, 2017). Ot is believed that commercial infusions sweetened with stevia are a viable option that can contribute to the health of people who consume them. The aim of this study was to compare TPC and AC in dehydrated plant material, infusions and residues of white, black, red, green, spearmint, stevia, lemon grass and chamomile teas with or not addition stevia leaves and processed stevia.
Change of crystallinity and mineral composition of fly ash with mechanical and chemical activation for the improvement of phosphate uptake

A detailed investigation of the development of the mineral composition and crystallinity of fly ash (FA) activated by an integrated process, as well as the relation between that development and phosphate uptake (PU) in solution, was conducted. This process, consisting of pretreatment (mechanical milling), alkali fusion (sodium hydroxide) at 550 °C and acid attack (3 mol L—1 sulfuric acid), exhibited a remarkable activation effect. One-hour grinding could enhance PU from 0.67 to 1.66 mg PO4 3—-P g —1 FA, and then under the optimum chemical conditions with the ratio of NaOH to FA of 0.5 g g—1 and that of H2SO4 to FA of 3 mL g— 1, the PU was further improved to 7.14 mg g— 1. Results also indicated that the PU performance was closely linked with the crystallinity and mineral composition of FA, that is, the treated material with the lowest crystallinity and least crystal phase could achieve the highest PU. For the purpose of destroying original minerals in raw FA farthest and avoiding the production of new crystals, therefore, control on the ratio of NaOH to FA and that of acid to FA was very important during the chemical treatment.
Perimenstrual Distress and Coping Responses among College Women

The purpose of this study was to investigate the prevalence of menstrual distress and coping responses in college women and to provide basic data for nursing management of women with menstrual distress. In a descriptive cross-sectional study, 233 female college students who study at S university were included. They completed an online structured survey containing the menstrual distress questionnaire and menstrual coping responses. The mean of menstrual distress experienced by participants was 2.51 in a scale of 1 to 5. The mean score of subcategories of menstrual distress was 2.61 for pain, 2.14 for impaired concentration, 2.52 for behavior change, 2.31 for autonomic reactions, 2.69 for water retention, and 2.82 for negative affect. The subjects used an average of 9.38 coping responses out of a possible 24 items to cope with their menstrual distress, and also that the ones they used were less effective. Also, the study found a negative affect of menstrual distress was correlated with avoidant coping of menstrual coping responses. Therefore, it is necessary to educate female college students to recognize the period properly and manage their menses symptoms in a positive and effective manner.
Amphetamine

Summary Amphetamine markedly enhanced the pressor potency of intraduodenally administered tyramine in rats. This enhancement of the pressor potency of tyramine by amphetamine is comparable to that reported for monoamine oxidase inhibitors(3). The potentiation was observed following either intravenous or intraduodenal administration of the amphetamine.
