Cyclic shear angle for lamellar chip formation in ultra-precision machining

Shear angle is classically considered constant. In the study, a series of straight orthogonal cutting tests of ultra-precision machining revealed that shear angle cyclically evolved with each lamellar chip formation, i.e. cyclic shear angle. It grew up from an initial shear angle of 0° to a final shear angle 90°-α (α: tool rake angle) and underwent a series of transient shear angles like classical shear angles and a critical shear angle. The critical shear angle is the sum of the half of the tool rake angle and the characteristic shear angle determined by material anisotropy without the friction effect. Moreover, a new model was developed. Further, a series of face turning tests of ultra-precision machining verified that the cyclic shear angle was the intrinsic mechanism of cyclic cutting forces and lamellar chip formation to induce twin-peak high-frequency multimode diamond-tool-tip vibration. Significantly, the study draws up an understanding of shear angle for the discrepancy among the classical models.
Stock returns and calendar anomalies on the London Stock Exchange in the dynamic perspective of the Adaptive Market Hypothesis: A study of FTSE100 & FTSE250 indices over a ten year period

This paper analyses the behaviour of stock returns and calendar anomalies over a ten year period: 2007–2016 on the London Stock Exchange, through two major indices, the FTSE100 and FTSE250. The efficiency of the indices and the presence of calendar anomalies are investigated with parametric and non-parametric tests. The two main indices of the UK stock market undergo changes from states of dependency of returns to independence of returns and vice versa, but their behaviour is not concomitant. This study finds that financial markets in the UK can undergo changes from states of inefficiency moving to efficiency and vice versa in support of the Adaptive Market Hypothesis. This study also captures the inconstant and time varying behaviour of calendar anomalies and their occurrence. This again supports the Adaptive Market Hypothesis. Overall, it enables investors to get a better understanding of the behaviour of stock returns and to devise profitable investment strategies according to market conditions.

Palabras clave: Anaplasma marginale, VirB9, VirB10, CTP, Ef-Tu. IDENTIFICATION OF GENES CODIFYING FOR VIRB9, VIRB10, CONJUGAL TRANSFER PROTEIN AND ELONGATION FACTOR TU OF AN ANAPLASMA MARGINALE CUBAN ISOLATE ABSTRACT: From the sequencing of the entire genome of Anaplasma marginale isolates, genes encoding membrane proteins of this hemoparasite have been identified, as well as novel immunogens as potential vaccine candidates. However, little is known about the genetic variability of genes encoding membrane proteins of Anaplasma marginale isolates. The aim of this study was to determine the degree of conservation of the genes encoding the VirB9, VirB10 proteins, conjugal transfer protein (CTP) and the elongation factor ( Ef-Tu) in the nucleotide sequence of a Cuban Anaplasma marginale isolate and from the deduced amino acid sequence and compare them with those described for Florida and Saint Maries Anaplasma marginale isolates and Anaplasma (centrale) marginale from Israel . The gene and deduced amino acid sequences showed high degree of identity with the sequences described for other isolates of Anaplasma marginale . Key words: Anaplasma marginale , VirB9, VirB10, CTP, Ef-Tu.
Impact of Family Dependents on Asthma

Asthma and Chronic Obstructive Pulmonary Disease (COPD) are increasing at a rapid pace in the last decade [1]. Research is going on, but the fact remains that prevalence is on the increasing trend, confirmed by CDC reports. A study conducted on Asthma patients related to socioeconomic factor like family size or number of dependents in the family and found out that among asthmatic patient there are few factors which significantly affect asthmatic patients [2].
Wild Horses of the Great Basin: Social Competition and Population Size

A liquid nail polish which imparts improved flexural strength to the human nail and inhibits splitting when applied thereto as a coating. The nail polish formulation is characterized by the inclusion therein, as a dissolved component, of a small but effective amount of a terpolymer comprising a copolyamide consisting essentially of recurring units of equimolecular proportions of caprolactam, laurolactam and hexamethylene diamine adipate. Typically, said terpolymer is first dissolved in a mixture of trichloroethane and ethyl alcohol, and this liquid solution is added in a small quantity to a stock liquid nail polish formulation so that a final formulation containing a small but effective amount of said dissolved terpolymer is produced, e.g. a formulation containing in the range of about 0.001 to 0.1% by weight of said dissolved terpolymer.
Características fermentativas e químicas de silagens de capim-elefante contendo subproduto da mandioca

The aim of this work was to evaluate the elephant grass silage nutritive value with increasing levels (0; 5; 10; 15 and 20%) of by-product of the cassava - SM in relation to the grass fresh matter. It was used a complete randomized design with four replications. 20 PVC silos have been used, each one having 100 mm in diameter and 350 mm in length. After 39 days the silos were opened, silage samples were collected samples for determination of dry matter (DM), crude protein (CP), neutral fiber detergent (NDF), acid fiber detergent (ADF), cellulose (CEL), hemicelluloses (HC), lignin contents (LIG) and silages pH values. In the level of 7,1% of SM addition, the silages reached the suitable dry matter content (30-35%) to occur a good fermentative process. The minimum level of CP (7%) was not reached in any level of SM. The FDN, FDA and CEL levels decreased with SMD addition. In all the levels of SM addition, the silages have been kept under appropriate pH values to well conserved silages (3,8-4,2). The SM addition up to the 20% level (on a grass fresh matter basis) at the elephant grass ensiling sponsored a good fermentative pattern and a better silage chemical composition.
Fifty-five years and counting: A half-century of getting it half-right?

I don’t have much in common with the great Irish author James Joyce. I certainly don’t share his talent as a writer, but what he and I have in common is that we cut our teeth as English as a foreign language (EFL) teachers in the Berlitz system. The Berlitz language schools were founded by Maximilian Berlitz (1852–1921). All teaching followed the structural-oral method. Listening and speaking were paramount; reading and writing only came later. Grammatical terminology was outlawed in the initial stages. You taught from ‘the book’; I still own a copy (Berlitz, 1966). Grammar was delivered in the form of substitution drills like the one at the beginning of this article; only later, when the structural patterns were internalised and had become automatic, could discussion of grammar take place. Berlitz did not invent the oral-structural method; figures such as Harold E. Palmer also published several books for the learning of English in which substitution drills played a major part (e.g. Palmer, 1916, 1922), and plenty were to follow. Both Palmer and Berlitz represented a reaction against the philological tradition of the late nineteenth century and the grammar-translation approach. Palmer was doubly innovative and years ahead of his time, publishing a spoken grammar which should be compulsory reading on any EFL/ESL (English as a second language) teacher training course (Palmer, 1924). Being a Berlitz teacher was relatively easy; you delivered the book and made sure the students’ responses were not too far wide of the mark. You didn’t need any qualifications or training or to have heard of structuralism or the oral method. It was enough to be a native speaker of English and to display sufficient enthusiasm. Perhaps James Joyce also found the job undemanding. He was a Berlitz teacher during his sojourn in several European countries in the first two decades of the twentieth century (Bowker, 2011). He too seems to have found the Berlitz method restrictive, with no freedom to expand creatively or opportunities for spontaneity, especially at the beginner level. Joyce was known to depart from the Berlitz script in his classes (Gottfried, 1979). I too departed from the script, but did so in a whisper, in case the boss would pass by the room and hear me engaging in real conversation with the students.
Intra Frame Rate Control for Versatile Video Coding with Quadratic Rate-Distortion Modelling

With numerous coding tools adopted in the forthcoming Versatile Video Coding (VVC) standard, much less work has been dedicated to study the corresponding Rate-Distortion (R-D) characteristics. This paper proposes a new quadratic R-D model for Versatile Video Coding. In particular, based on the proposed model, a new R-λ relationship is derived and used for frame level rate control. The rate control algorithm is implemented on VTM 2.0 platform for intra coding scenarios. Compared to the default rate control algorithm in VTM 2.0, experimental results show that proposed rate control algorithm can achieve 0.77% BD-BR reduction with similar control accuracy.
B-PRED: AN INTELLIGENT AND ADAPTABLE MEDICAL DIAGNOSIS SYSTEM BASED ON BAGGING MACHINE LEARNING

— Advancement in medical information systems has facilitated the development of automated diagnosis systems. Several Artificial Intelligence (AI) techniques have been implemented and studied in modern researches to come up with the most suitable and accurate medical diagnosis system. Bagging is one of these techniques, and it has been proven by several researches to be a powerful and convenient tool for such systems. In this research; bagging algorithm is used to produce a diagnosis system for two of the most common diseases: diabetes and heart diseases, where this algorithm used verified datasets of attributes that are combined with the same attributes values submitted by the patient through a dedicated interface. Testing the system and comparing it to other prediction systems proved its efficiency and accurate prediction rates.
Translocated native pine martens
 Martes martes
 alter short‐term space use by invasive non‐native grey squirrels
 Sciurus carolinensis

Handling Editor: Matt Hayward Abstract 1. Predators can shape the distributions and dynamics of their prey through direct and indirect mechanisms. Where prey animals are regarded as pests, the augmentation of predator populations might offer a potential tool in their management. 2. Declines in invasive non-native grey squirrel Sciurus carolinensis populations in Ireland and Scotland have been related to an increase in range and density of native pine marten Martes martes populations. These reductions in grey squirrel abundance have, in turn, been linked to recovery of native red squirrels Sciurus vulgaris. 3. Taking the opportunity presented by a conservation translocation of pine martens from Scotland to Wales, we investigated the short-term effects of exposure to translocated martens on the space use and survival of resident grey squirrels. 4. Grey squirrel range size and daily distance travelled increased significantly with increasing exposure to martens but we found no effect of marten exposure on the recapture probability (i.e. apparent survival) of the sampled squirrels within the study time frame. This is suggestive of contemporary, non-lethal effects changing the ranging or foraging regimes of squirrels, due either to predator avoidance and/ or earlier lethal effects associated with a reduction in intraspecific competition. 5. Synthesis and applications. Our evaluation mimics the conditions experienced by grey squirrels at the front edge of naturally recovering pine marten populations and presents direct evidence that pine marten translocations could play an influential role in the behaviour and dynamics of invasive non-native grey squirrel populations. Translocations of native predators, undertaken primarily for biodiversity conservation, could therefore find additional application in managing the ecological and economic impacts of invasive non-native prey.
Distribution Channel Choice and Divisional Conflict in Remanufacturing Operations

We consider a firm consisting of two divisions, one responsible for designing and manufacturing new products and the other responsible for remanufacturing operations. The firm will sell these new and remanufactured products either directly to the consumer (direct selling) or through an independent retailer (indirect selling). Our study demonstrates that a firm’s organizational structure can affect its marketing decisions. Specifically, a decentralized firm with separate manufacturing and remanufacturing divisions can benefit from indirect selling with higher firm profit, supply chain profit, and total consumer demand than direct selling. Moreover, this structure also induces a remanufacturable product design. In contrast, a centralized firm in which the manufacturing and remanufacturing divisions are consolidated is intuitively better off by choosing direct selling than indirect selling. Furthermore, we show that, surprisingly, when the focal firm sells through an independent retailer, a decentralized internal structure can result in higher supply chain profit than a centralized internal structure. We further investigate the case of dual dedicated channels and conclude that, while direct selling of remanufactured products and indirect selling of new products can better induce a remanufacturable product design and higher supply chain profit, it is not in the best interest of the firm in terms of total sales and firm profit.

Struktureller und sozio-demographischer Wandel der Arbeitswelt und Änderung der beruflichen Mobilität in Deutschland 1980-2010

The changes in the world of work and the development of occupational mobility can be important from a health and prevention perspective. E.g. mobility can lead to immigration into stressintensive occupations and structural changes to the emergence of new types of work-load. However, so far a common analysis over a longer time period is missing in Germany. The aim of this study is to describe the demographic and structural changes in the world of work and in occupational mobility using selected indicators. We focus on specific socio-demographic indicators and study mobility as inter-company (change of employer), inter-occupational (change of occupation), intersectoral (change of economic sector) and interregional (change of province).
Comparison of GTO-ECV and adjusted MERRA-2 total ozone columns from the last 2 decades and assessment of interannual variability

Abstract. In this study we compare the satellite-based Global Ozone Monitoring Experiment (GOME)-type Total Ozone Essential Climate Variable (GTO-ECV) record, generated as part of the European Space Agency's Climate Change Initiative (ESA-CCI) ozone project, with the adjusted total ozone product from the Modern Era Retrospective Analysis for Research and Applications version 2 (adjusted MERRA-2) reanalysis, produced at the National Aeronautics and Space Administration (NASA) Global Modeling and Assimilation Office (GMAO). Total ozone columns and associated standard deviations show a very good agreement in terms of both spatial and temporal patterns during their 23-year overlap period from July 1995 to December 2018. The mean difference between adjusted MERRA-2 and GTO-ECV 5 ∘ × 5 ∘ monthly mean total ozone columns is - 0.9 ± 1.5 %. A small discontinuity in the deviations is detected in October 2004, when data from the Ozone Monitoring Instrument (OMI) were ingested in the GTO-ECV and adjusted MERRA-2 data records. This induces a small overall negative drift in the differences for almost all latitude bands, which, however, does not exceed 1 % per decade. The mean difference for the period prior to October 2004 is - 0.5 ± 1.7 %, whereas the difference is - 1.0 ± 1.1 % for the period from October 2004 to December 2018. The variability in the differences is considerably reduced in the period after 2004 due to a significant increase in data coverage and sampling. In the tropical region, the differences indicate a slight zonal variability with negative deviations over the Atlantic, Africa, and the Indian Ocean and positive deviations over the Pacific. Ozone anomalies and the distribution of their statistical moments indicate a very high correlation among both data records as to the temporal and spatial structures. Furthermore, we evaluate the consistency of the data sets by means of an empirical orthogonal function (EOF) analysis. The interannual variability is assessed in the tropics, and both GTO-ECV and adjusted MERRA-2 exhibit a remarkable agreement with respect to the derived patterns. The first four EOFs can be attributed to different modes of interannual climate variability, and correlations with the Quasi-Biennial Oscillation (QBO), the El Nino–Southern Oscillation (ENSO) signal, and the solar cycle were found.
Identification of Downstream Targets of the Putative Transcription Factor Prdm8

The putative transcription factor Prdm8 is a member of the PR domain-containing protein family, which are regulators of cell proliferation and differentiation. Prdm8 is expressed in the developing and adult retina, most abundantly in the inner nuclear layer, where retinal bipolar interneurons reside. Adult /eGFP retinas have a near complete absence of rod bipolar and Type 2 OFF cone bipolar cells. Prdm8 is required for late bipolar cell differentiation. To begin to identify downstream targets of Prdm8, I compared gene expression of wild-type and /eGFP retinas at P6 by microarray analysis. I identified 75 differentially expressed genes, many of which are involved in neurogenesis and neurite development. Differentially expressed genes include transcription factors such as Sox6 (2.4-fold up in mutant), Lhx4 (1.6-fold up), and Eomes (1.4-fold down). Differentially expressed genes of the /eGFP retina are strong candidates to be controlled by Prdm8, suggesting Prdm8 may function in a transcription factor cascade that regulates late bipolar cell differentiation.
Can societal impact of scientific work be measured in the process of re-accreditation of higher education institutions and public scientific institutes in Croatia?

In this paper we present an approach to measuring the societal impact of scientific research. Our proposed methodology is based on the theory of productive interaction (Spaapen and van Drooge, 2011). The methodology was tested on the reports produced in the process of the expert evaluation of public higher education institutions (HEIs) at universities and public research institutes in Croatia. For the purpose of quantitative assessment, we have developed a conceptual framework and analyzed the narrative texts of reports based on recognising codified interactions. Finally, we discuss our results in the context of the research area of the Republic of Croatia in the fields of social sciences and biomedicine.
Detection of bovine coronavirus in calf diarrheic samples by indirect antigen capture ELISA and RT-PCR.

In the present study, 160 fecal samples were collected from clinical cases of diarrheic calves from different Indian states covering eight dairy farms of Uttar Pradesh, Tamil Nadu, and Karnataka and dead calves of Bareilly region. The fecal samples from all these cases were screened for the presence of bovine coronavirus (BCoV) by using commercially available indirect antigen capture ELISA kit. Furthermore, all samples were subjected to RTPCR for detection and confirmation of BCoV. RT-PCR was done by using two different types of primers to amplify the conserved nucleocapsid (N) gene of the virus targeting a 407 bp and 730 bp gene fragments of BCoV. Out of 160 cases, 5.63% (9/160) and 9.38% (15/160) of cases were positive for BCoV by ELISA and RT-PCR, respectively. Further, all the reported cases are from the Bareilly region of Uttar Pradesh with incidence rate of 9.38% (11/65). In conclusion, indirect antigen capture ELISA can be employed for the rapid detection of bovine coronavirus in diarrhoeic cases in fecal samples; however RT-PCR is more sensitive than ELISA for detection of coronavirus in diarrheic cases. Further studies are needed on bovine coronavirus to isolate from different parts of our country, to characterize them at genomic levels thereby investigating their antigenic and genetic properties and to check strain variations.
