Artificial long days increase milk production in subtropical lactating goats managed under extensive grazing conditions

SUMMARY The objective of the current study was to determine whether exposure to an artificial long-day photoperiod increases milk production in subtropical goats maintained under extensive grazing conditions, with or without the presence of a nutritional supplement. Forty-four lactating goats were exposed to a natural photoperiod (11 h light) with nutritional supplementation (NDS; natural day supplemented group; n=11) or without nutritional supplementation (NDN; natural day non-supplemented group; n=11) or to an artificial long-day photoperiod (16 h light) with nutritional supplementation (LDS; long-day supplemented group; n=11) or without nutritional supplementation (LDN; long-day non-supplemented group; n=11). Daily nutritional supplementation consisted of a mixture of 300 g rolled maize and 200 g soya bean per animal. During the suckling phase, milk yield was assessed at 10 and 20 days lactation and thereafter every 10 days up to 110 days lactation from day 40 of lactation. Plasma insulin-like growth factor 1 (IGF-I) concentration was determined at 20, 40, 60, 80 and 100 days of lactation. Mean milk yield was greater in goats from the LDN group than the NDN group. The difference in mean milk yield was greater when goats received a nutritional supplement. With nutritional supplementation, the plasma IGF-I concentrations were greater in goats exposed to long days than in those maintained under natural photoperiod. However, IGF-I concentrations were lower with long days when goats were not supplemented. In conclusion, exposure to an artificial long-day photoperiod increases milk yield in subtropical lactating goats maintained under extensive grazing conditions, and this increased milk production is more pronounced with a nutritional supplement. Furthermore, depending on nutritional status, exposure to artificial long days increases plasma IGF-I concentration in lactating goats.
Report about Myelodysplasic Syndrome / Myeloproliferative Neoplasm with Ringed Sideroblasts and Thrombocytosis ( Mds / Mpn-RsT ) and Review of

Case Report MDS/MPN-RS-T is a clinical-biological entity of haematological malignancies border between myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN), declared in 2016 by WHO as a separate entity of its own unlike old classifications. Its particularity lies in the association of an MDS with ringed sideroblasts (MDS-RS) with a MPN represented in this case by its similarity to an essential thrombocytemia (ET) because of thrombocytosis. Clinically, the association of splenomegaly with chronic "refractory" anemia guides the diagnosis. Cytology is a largescale orientation tool. It sometimes targets some signs of peripheral dysgranulopoiesis with thrombocytosis and giant platelets. Bone marrow smear shows hyperlobed megakaryocytes (similar as those found in ET or primary myelofibrosis (PMF), sometimes cytoplasmic degranulation of the granular line and often many signs of dyserythropoiesis with more than 15% of ringed sideroblasts (RS) in Prussian blue staining. However, the molecular study retains its full scope to confirm the diagnosis by objectifying the mutation SF1B3 (spliceosome gene) generally found in MDS-RS, accompanied by the mutations found in negative BCR-ABL MPN (JAK2, CAL-R and MPL), thus explaining the hybrid nature of this rare myeloid entity. This genotype can be more complex when associated with other mutations characteristic of MDS (ASXL1, DNMT3A, SETBP1 or TET2) thus worsening the prognosis of patients. We report here a case of a 56-year-old patient followed for ET whose diagnosis was renewed in MDS / MPNRS-T by cytology and molecular biology.
Extensions of index theory inspired by quantum scattering theory (17frg668)

On the geometric side following from [6] the work of Carey, Grosse and Kaad has introduced a new spectral invariant the ‘homological index’ [9, 7]. This homological index provides the appropriate framework for a major extension of older ideas of R. Carey and J. Pincus [10] on almost commuting operators. It is expressed as a pairing of a new cyclic homology theory developed in [9] with its dual cohomology theory. An open question is whether we can relate the homological index to the spectral shift function. In addition we want to know if it is possible to use cyclic theory to investigate the latter and conversely use the spectral shift function to calculate the homological index.
Seasonal Variation of In Situ Nitrogen Fixation (C 2 H 2 Reduction) in an Expanding Marsh of Spartina Anglica

(1) Acetylene reduction associated with an expanding Spartina anglica marsh and adjacent sediments was measured using an in situ assay. (2) The seasonal trend of sedimentary acetylene reduction showed low levels during winter and higher rates in the warmer months with a midsummer peak. This activity was mainly due to bacteria in the surface layer of the sediments. (3) Acetylene reduction within the S. anglica sward was generally greater than in uncolonized sediments and was due largely to bacteria associated with the plant roots. This activity was less temperature-sensitive than that of uncolonized sediments and reached a maximum in late September. (4) The total annual nitrogen fixation estimated for the young, developing area of this marsh was insufficient to supply more than 2-3% of the plants' nitrogen requirements. In contrast, fixation in the established zones was up to 100 times higher and could contribute significantly to plant growth. It is likely, therefore, that nitrogen fixation is not a contributory factor in the rapid spread of S. anglica but is more a feature of the established plant in stablilized sediments.
Learn-ing-Based On-AP TCP Performance Enhancement

Data transmissions suffer from TCP’s poor performance since the introduction of the first commercial wireless services in the 1990s. Recent years have witnessed a surge of academia and industry activities in the field of TCP performance optimization. For a TCP flow whose last hop is a wireless link, congestions in the last hop dominate its performance. We implement an integral data sampling, network monitoring, and rate control software-defined wireless networking (SDWN) system. By analysing our sampled data, we find that there exist strong relationships between congestion packet loss behaviors and the instant cross-layer network metric measurements (states). We utilize these qualitative relationships to predict future congestions in wireless links and enhance TCP performance by launch necessary rate control locally on the access points (AP) before the congestions. We also implement modeling and rate control modules on this platform. Our platform senses the instant wireless dynamic and takes actions promptly to avoid future congestions. We conduct real-world experiments to evaluate its performance. The experiment results show that our methods outperform the bottleneck bandwidth and RTT (BBR) protocol and a recently proposed protocol Vivace on throughput, delay, and jitter performance at least 16.5%, 25%, and 12.6%, respectively.
The Impact of Using Emergency Lights and Sirens During Noncritical PatientTransport

Introduction: Unnecessary use of lights and sirens during transport of noncritical patients is a major cause of vehicle crashes contributing to injury and death among emergency medical technicians (EMTs), patients and bystanders. This study examines whether EMT stress levels and ambulance transport times differ as a function of using lights and sirens, and whether EMTs support policies for their use. Methods: Data for this quasi-experimental quantitative study was collected from 80 New Jersey EMTs using the Depression Anxiety Stress Scale. Results were assessed for ambulance transport times for noncritical patients and EMT stress levels, both with and without the use of lights and sirens. Data were analyzed using the t test and regression procedures. Results: Analysis shows no statistically significant difference in transport times with lights and sirens in use compared to when they were not used. Findings are statistically significant in the undue and increased stress level of the EMTs when lights and sirens are used. Participants demonstrated support for a policy for their use. Conclusion: Findings suggest that the use of lights and sirens in transporting noncritical patients is unnecessary. Practical applications: Recommendations include the development of a state Emergency Medical Services policy to provide guidelines on the use of lights and sirens, or a system that allows for the objective evaluation of whether the situation warrants the use of lights and sirens. The implications for positive social change include savings of money, property and, most importantly, human lives.
The impact of insurance status on the survival outcomes of patients with renal cell carcinoma

Background The impact of insurance status on renal cell carcinoma (RCC) patient survival is unclear. In this study, we investigated the effects of insurance status on the survival outcomes of RCC patients in the United States of America. Methods Data of patients diagnosed with RCC between 2007 and 2014 were obtained from the Surveillance, Epidemiology and End Results (SEER) database, a large national database including statistics on cancer patients. The Kaplan-Meier method and Cox regression analysis were used to determine the influence of insurance status on cancer-specific survival (CSS). Results A total of 30,951 eligible RCC patients were identified. Of these patients, 25,493 (82.37%) were insured, 3,959 (12.79%) had any Medicaid coverage, and 1,499 (4.84%) were uninsured. Kaplan-Meier analysis revealed that insurance status was associated with better CCS (P<0.001). The 5-year CSS rates of patients with insurance, any Medicaid, and no insurance were 88.3%, 82.6%, and 82.7%, respectively. Multivariate Cox regression analysis showed that patients with any Medicaid had poorer CSS than insured patients [hazard ratio (HR), 1.222; 95% confidence interval (CI), 1.100–1.357]. Stratified analysis revealed that at localized tumor stage and at regional tumor stage or among white patients, any Medicaid insurance was an independent predictor of an unfavorable survival outcome. Conclusions Among the RCC patients in this study, individuals with insurance experienced improved CSS while individuals with any Medicaid tended to suffer worse survival outcomes.
The Effects of Demographic Factors on Kenya Economic using Multiple Linear Regression Analysis

Kenya’s economy is a market-based with a few stateowned infrastructure enterprises and maintains a free external trade system. The country is generally perceived as Eastern and central Africa's nave for Communication, Financial and Transportation services. The major industries that lead to the increment of the country’s economy include; agriculture, fishing and forestry, mining and minerals, industrial manufacturing, energy, tourism, and financial services. The general objective of the study was to examine the effects of births, deaths and net migration to the Kenyan economy. This study takes into account the predictor variables as birth rates, death rates, and net migration and the explained variable as the GDP per capita growth which acts as the indicator of the economy with an application of multiple linear regression model. The findings of the study support the existence of a short-run relationship between population growth and economic growth in Kenya. The causality test is bi-directional causality between population growth and economic growth. Kenya is termed as the second stage of demographic transition. The study used a secondary data source from www.knbs. or.ke and www.aphric. org. The variables of interest were birth rates, death rates, net migration rates and the country’s Per capita GDP in Kenya. This study is of great importance to the researchers in the field of population, economic growth policymakers, and academicians.
Antimicrobial activity and green synthesis of silver nanoparticles using Trichoderma viride

ABSTRACT Green synthesis of nanoparticles has an increasing benefit because of the rising need for developing environmentally friendly, cost-effective and safe strategies for nanomaterials synthesis. In this study, we investigated the fungus Trichoderma viride, which is used for the synthesis of biogenic silver nanoparticles. The bioreduction of silver nanoparticles (Ag NPs) was observed spectrophotometrically, and the studied Ag NPs were characterized by ultraviolet–visible spectroscopy (UV–Vis), transmission electron microscopy and scanning electron microscopy. The Ag NPs synthesized by T. viride were observed as stabilized and polydispersed globular particles, in sizes ranging from 1 to 50 nm. The antibacterial potential of Ag NPs was evaluated against human pathogenic bacteria. The biogenic Ag NPs significantly inhibited the growth of all tested pathogenic bacteria.
Capabilities, Innovation and Performance of Brazilian Exporting Firms

Premised on the resource-based view and dynamic capability perspective, we examine the differential and interactive effects of the exploration and exploitation capabilities in new product development for external markets and in overall performance. In addition, we test the moderate effect of market dynamism and the control effect of firm size on these relationships. Our model was tested with data from 498 Brazilian exporting firms, applying structural equation modeling (SEM). We found support to the hypotheses that exploitation capabilities influence both product innovation and performance, whereas exploration capabilities and its interaction with exploitation influence performance but not product innovation.
Spatial utilization by black-backed jackals in southeastern Botswana

Space use by black-backed jackals was investigated between November 1995 and February 1997 in the Mokolodi Nature Reserve (MNR) in southeastern Botswana. Mean aggregate home-range size for the three radio-collared jackals was 15.9 km2. Mean home-range size varied between seasons with a tendency for range expansion during winter. The first two radio-collared jackals had similar activity patterns and were most active at dawn and dusk. Distances moved between hourly re-locations ranged from 2 m to 3000 m, and average distances moved between hourly relocations differed between individuals. The mean distance travelled per 24-hour period was 14.6 km. Time of day influenced movements considerably, with greater distances being moved during dawn and dusk. Extraterritorial excursions directed towards farmland were frequent and accounted for 21.1 % (n = 66) of all radio relocations. Jackals in MNR utilized wooded cover for denning, predator avoidance and foraging. They did not use habitats according to their proportional availability in any season. In all seasons jackals used open savanna grassland, Croton/Combretum tree savanna, and seasonal floodplains less than expected from their availability, and used tree and bush savanna, semi-sweet mixed bushveld and agricultural areas much more than expected. Implications of space use by jackals on management and conservation are discussed.
Efficient and cost-effective seismic design using inelastic analysis procedures and overstrength

This paper discusses the advantages of a simple approach that utilizes inelastic analysis procedures (IAPs) in seismic design. Two sets of mediumand high-rise buildings of different structural systems and heights are employed to describe and verify the approach. Fiberbased numerical models and diverse input ground motions are employed in the dynamic response simulations. The correlation of the results obtained from different IAPs and elastic analysis procedures (EAPs) suggests utilizing a simple measure of response for assessing the initial design. This measure reliably describes the anticipated behavior of the structure under the design earthquake. Nonlinear response history analysis (NRHA) is recommended to refine the initial design if the response was outside a favorable range. The proposed refinement in seismic design effectively exploits IAPs and first yield overstrength, and helps designers to obtain more reliable and economical design of building with different structural systems and heights.
Inference of Genetic Lineages of Fagus crenata Populations in Shizuoka Prefecture Based on Chloroplast DNA and Nuclear Microsatellite Variations.

静岡県のブナ集団の遺伝的系統を推定するため, まずブナの分布域全体にわたる55集団を用いて葉緑体DNA (cpDNA) ハプロタイプの地理的分布を調べた。 調査した集団にはハプロタイプD, EおよびFの3種類が存在し, 中部地方の太平洋側に分布するDとEが大部分を占めていた。 次にブナの分布域および明らかとなったハプロタイプの地理的分布にもとづいて6集団を選定し, 核マイクロサテライト (nSSR) により遺伝的多様性を調査した。 nSSR座の対立遺伝子頻度から計算された集団間のDA距離にもとづいた無根近隣結合樹から, 調査した集団は全て太平洋側の系統群に属し, 地理的な位置関係と一致することが明らかとなった。 nSSR座の対立遺伝子頻度は集団間でほぼ均一であったが, cp DNAハプロタイプの地理的分布には構造が認められた。 この差異はcpDNAと核DNAの遺伝様式に起因する遺伝子流動率の違いを反映していると考えられる。
Orchard and bin treatment with entomopathogenic nematodes (Rhabditida: Steinernematidae and Heterorhabditidae) for the control of the codling moth (Cydia pomonella)

The codling moth, Cydia pomonella (Lepidoptera: Tortricidae), is the key pest of apples and pears worldwide. The withdrawal of certain fundamental chemicals from codling moth management spray programmes, due to concerns about human, environmental and ecosystem health, has resulted in the search for softer, more environmentally friendly, and safer control measures. Entomopathogenic nematodes (EPNs), naturally occur in the soil, and actively search for hosts. The interest in using EPNs from the families Heterorhabditidae and Steinernematidae as a control measure was sparked in 1953, when an EPN was discovered in an insect. The aim is to incorporate EPNs in an integrated pest management (IPM) programme, to ensure minimal residue and eventually residue-free pome fruit production in South Africa. In order to ensure EPN success, both the environmental and technical factors influencing their efficacy, were investigated in this study. The biocontrol potential of three imported EPN isolates, being Steinernema feltiae and two isolates of Heterorhabditis bacteriophora (Hb1, Hb2), as well as a local isolate, Steinernema yirgalemense, were evaluated for the control of the codling moth under local conditions. All concentrations of S. yirgalemense, applied by immersion in a suspension of nematodes, gave > 98% control. The two formulated isolates of H. bacteriophora, Hb1-f and Hb2-f, gave < 30% control. When using the same nematode isolates, produced in vivo, S. yirgalemense still resulted in a higher codling moth control of > 90%, compared to 54% and 31% control of the H. bacteriophora Hb1 and Hb2 isolates, respectively. In follow up field trials, S. feltiae resulted in ≥ 80% control, and was thus more effective than both S. yirgalemense and the H. bacteriophora (Hb1) isolates, with 66% and 24%, and 24% and 9% control, for two separate trials, respectively. To validate the data obtained from the field trials, subsequent laboratory bioassays were conducted evaluating temperature regimes, following the same cycle as under natural conditions, with a constant humidity of 100%. Steinernema feltiae proved to be most effective, causing > 90% mortality, followed by S. yirgalemense, with 78% mortality. The two H. bacteriophora isolates (Hb1, Hb2) under the above-mentioned laboratory conditions, resulted in 73% and 59% control, respectively. Humidity thus seems to be the most important factor affecting EPN efficacy during above-ground applications. Steinernema feltiae proved to be a better candidate than S. yirgalemense for the control of the codling moth. Stellenbosch University https://scholar.sun.ac.za

Modeling Heterogeneity in Firm-level Return Predictability with Machine Learning

Recent studies have exploited machine learning techniques to explore whether firm-level returns exhibit some predictability when high-dimensional characteristics are used. However, the presence of heterogeneity in the crosssection has not yet been investigated using these methods: do different characteristics matter for different types of firms? We show that allowing heterogeneity in predictive relationships results in increased out-of-sample predictability of firm-level returns, while improving interpretability thanks to the use of sparse linear models. These sparse models allow us to answer the question of which characteristics matter for which firms, and their empirical success suggests that models combining sparsity with heterogeneity are useful for studying the cross-section of returns. We achieve this by adapting machine learning techniques to our heterogeneous prediction problem. We also provide an overview of other machine learning techniques that are relevant to the heterogeneous predictability problem. Our results also indicate that developing customised machine learning methods for asset pricing is an important research direction that may shed new light on old economic questions.
Rainfall variability and its impact on change of cropping systems in Bihar

The mean annual rainfall of 19 years (1989–2008) of Bihar is 1138.2mm with standard deviation 158.6 mm and coefficient of variation 14%. Although Bihar falls under high rainfall region with recurrent floods but occurrence of droughts during monsoon season is also a serious concern. In present study, the variability and trends of annual and monthly monsoonal rainfall for all the districts of Bihar have been analyzed and due to change in rainfall, the district-wise change in area of rice, wheat and maize has also been evaluated. There is 0.5% increase in mean annual rainfall during 1999–2008 as compared to 1989–1998. Month August is the 2nd wettest month in all the districts except Purnia and Katihar during the 1st period. On the other hand, the districts such as Nalanda, Munger, Sheikhpura, Jamui, Bhagalpur, Banka, Saharsa, Madhepura, Purnia, Katihar and Khagaria have been observed 2nd wettest month in September during 2nd period. Rainfall variability caused a change of -5.3% in rice area between triennium ending averages 1999–2000 and 2007–08. However, in case of wheat a meager increase of 1.6% was recorded. A slight change of -0.4% has been noticed during kharif maize, and 5.0 and 12.7%, in rabi and summer maize, respectively.As far as zonal change is concerned, all the zones, except zone IIIAhad a positive change in area of kharif maize and more over zone IIIB recorded a highest change of 57.7% due to decrease in monthly rainfall during August and September months. This feature compelled the farmers of the region to shift to kharif maize requiring less water
