Programs for fixed-time artificial insemination in South American beef cattle

Abstract Fixed-time artificial insemination (FTAI) has been widely applied in South America within the last 20 years for the genetic improvement of commercial beef herds. Most FTAI treatments for beef cattle used in South America are based on the use of progesterone (P4) releasing devices and estradiol to synchronize follicle wave emergence, with pregnancies per AI (P/AI) ranging from 40 to 60%. More recent protocols focusing on extending the interval from device removal to FTAI (i.e. increasing the growing period of the ovulatory follicle) have been reported to improve P/AI in beef cattle. These new protocols and the more traditional FTAI protocols have also been adapted for use with sexed-sorted semen with acceptable P/AI in beef cattle. Finally, color-flow Doppler ultrasonography has been incorporated recently to determine the vascularity of the CL and thereby detect pregnancy as early as Day 22 after the first AI for re- synchronization of ovulation for a second FTAI in non- pregnant animals. In summary, FTAI protocols have facilitated the widespread application of AI in South American beef cattle by allowing for the insemination and re-insemination of herds during a defined breeding season, without the necessity of clean up bulls to achieve high pregnancy rates.

Entrepreneurial culture and innovation in the services sector: case study evidence from Greece

Innovation in the services sectors has been a rather neglected research area under the commonly held view that manufacturing firms are the main drivers of innovation in developed economies. The rise of the service economy has redirected the research agenda towards the potential of services firms to adopt innovation activity. Here we analyze the determinants of innovation activity in the tourism industry, which is one of the fastest growing service industries in the world. Our analysis builds upon the theoretical notion of entrepreneurial culture in order to suggest that entrepreneurs possess such culture when they actively and consciously seek information in order to underwrite the risk and ambiguity inherent in actions such as innovation activity. At the empirical level, entrepreneurial culture is approximated by active engagement in networking activity. Our results indicate that both internal and external to the firm social capital generation processes, determine innovation activity in tourism and provide evidence over the selective nature of information networks.

The Effect of Exercise on the Timing of Aortic Valve Closure with Respect to the ECG Tracing

Objective: The temporal relationship between electrical repolarization of the heart and mechanical relaxation is not well quantified. In this study we examined the timing of the aortic valve (AoV) closure with respect to the electrical repolarization at rest and following exercise in young healthy subjects. Methods: We measured the period from the apex of the T wave (aT) to the beginning of the second heart sound (S2-aT) and the period from the apex of the T wave to the end of the T wave (eT-aT). Results: At rest, AoV closure occured immediately after the end of the T wave as evidenced by a ratio of (S2-aT)/(eT-aT) greater than 1. The mean time delay between the end of the T wave and AoV closure was 15.5ms which was only 4% of the QT interval duration. After exercise, AoV closure occured just before the end of the T wave (but after the peak of the T wave) as evidenced by the ratio of (S2-aT)/(eT-aT) being between 0 and 1. The mean time difference between the end of the T wave and AoV closure was - 4.4ms, which was only 1% of the QT interval duration. In combination, the QT and RR intervals account for some of the inter-subject variability. Conclusions: AoV closure closely approximates the end of T wave in healthy subjects indicating existence of electromechanical coupling during left ventricular relaxation. Clinically the end of T wave could, therefore, be used as a surrogate for AoV closure in healthy subjects.
Socialization and Identification of New Recruits in Knowledge Intensive Firms: A Case Study

Using the models from van Maanen and Schein (1977) and Dutton et al. (1994), we have been able to investigate the socialization process and organizational identification both from the organizational as well as the individual’s perspective. The link between these two perspectives establishes a better insight into the company’s actual socialization intentions and the individual’s identification with the firm. From our research it is indicated that the perceived organizational identity affects new recruits identification with the company in a strong sense. However this identification was not enhanced by the socializition tactics of either individualization or institutionalization. We have hence found factors within Alfa Laval which seemed to enhance new recruits identification and socialization with the company. These factors include a culture which is open, friendly, informal and international, and a working environment which is challenging but with full of opportunities. Addtionally a finding was that none of the new recruits could specifically state the values of the organization, but that they merely made up their own sets of perceived organizational values which they thought identified the company.
Heat Unit Model for Predicting Bloom Dates in Rubus

'Navaho' and 'Apache' blackberry plants were maintained at 10, 15, 20, 25, 30, or 35 °C in growth chambers to determine optimum temperature for budbreak and flowering (fewest days to flowering). In a separate experiment, bloom dates were observed for a collection of 117 Rubus genotypes over four seasons. Using these phenological data, predictive linear and curvilinear models were tested using a range of cardinal temperatures. The growth chamber experiment indicated optimum temperatures for bloom were 25.6 °C for 'Apache' and 29.2 °C for 'Navaho'. For the field observations, time to bloom was best defined by a linear model with base and optimum temperatures of 6 and 25 °C and a curvilinear model defined by base and optimum temperatures of 4 and 27 °C, respectively. Based on the linear growing degree hour (GDH) model, heat units to bloom varied among cultivars in the collection from 9,200 GDH for 'Chickasaw' to 18,900 GDH for 'Merton Thornless'.
Automated calibration of a stream solute transport model: implications for interpretation of biogeochemical parameters

The hydrologic processes of advection, dispersion, and transient storage are the primary physical mechanisms affecting solute transport in streams. The estimation of parameters for a conservative solute transport model is an essential step to characterize transient storage and other physical features that cannot be directly measured, and often is a preliminary step in the study of reactive solutes. Our study used inverse modeling to estimate parameters of the transient storage model OTIS (One dimensional Transport with Inflow and Storage). Observations from a tracer injection experiment performed on Uvas Creek, California, USA, are used to illustrate the application of automated solute transport model calibration to conservative and nonconservative stream solute transport. A computer code for universal inverse modeling (UCODE) is used for the calibrations. Results of this procedure are compared with a previous study that used a trial-and-error parameter estimation approach. The results demonstrated 1) importance of the proper estimation of discharge and lateral inflow within the stream system; 2) that although the fit of the observations is not much better when transient storage is invoked, a more randomly distributed set of residuals resulted (suggesting nonsystematic error), indicating that transient storage is occurring; 3) that inclusion of transient storage for a reactive solute (Sr2+) provided a better fit to the observations, highlighting the importance of robust model parameterization; and 4) that applying an automated calibration inverse modeling estimation approach resulted in a comprehensive understanding of the model results and the limitation of input data.
The interaction between moist diabatic processes and the atmospheric circulation in African Easterly Wave propagation

An objective tracking algorithm is used to characterize the three‐dimensional structure of African Easterly Waves (AEWs) in ERA‐Interim reanalysis and a Met Office Unified Model (UM) simulation. A special focus is dedicated to the coupling of dynamical aspects of the wave and moist convection. The relation between baroclinic features of the wave and latent heating is explored. Latent heating at and slightly ahead of the wave trough is found to reinforce and sustain the anomalous wave circulation through potential vorticity (PV) generation and vortex stretching. The coupling of moist processes and the circulation takes place mainly through moisture convergence at lower mid‐tropospheric levels, between 850 and 500 hPa. These findings are confirmed and examined in more detail in a case‐study of a strong AEW based on high‐resolution UM simulations. PV tracers are used to investigate how different moist diabatic processes invigorate the wave. Again moisture anomalies are found to be the main contributors to generating small‐scale convergence centres and updraughts ahead of the trough at mid‐tropospheric levels. Although buoyancy effects are ultimately responsible for the convective uplift, the results suggest that mesoscale circulations associated with the AEW dynamics are crucial in creating the small‐scale moist static instabilities and vortices which are essential for the AEW maintenance. Boundarylayer mixing and advection from the northern Sahel may create pockets of high‐PV air around the trough in some instances, but this mechanism of wave sustainment needs further investigation.
Stressful events in autobiographical memory processing: Brazilian version of the centrality of event scale

A stressful or traumatic event may become a central reference point in the organization of long-term memory, influencing the meaning of other experiences. The Centrality of Event Scale (CES) is an instrument in which participants recall the most traumatic event of their life and endorse 20 items. The CES was translated, adapted and validated for the Brazilian context in a sample of 195 undergraduates (75.8% women). The version obtained good internal consistency and significant correlation with a screening measure of Post-Traumatic Stress Disorder symptoms. New hypotheses on the cognitive processing of traumatic events are explored in the light of a factor analysis of the CES. Opportunities for CES use include monitoring cognitive patterns and therapeutic effectiveness in situations related to trauma.
Determining the impact of brand equity on consumer purchase intention

In this study, it was attempted to determine which brand equity element is more effective regarding the mobile phone purchase of university students. Brand equity is defined in three dimensions which are brand awareness, perceived quality and brand loyalty. Data was collected by 1190 subjects studying at the faculties of Aksaray University. The data was tested by Structural Equation Modeling. As a result of the research, it was found that brand awareness affects perceived quality, but it does not affect the brand loyalty and overall brand value. Perceived quality affects brand loyalty and overall brand value, while the brand loyalty affects the overall brand value. Furthermore, it was found that overall brand value affects purchase intention.
Phospholipid polymer can reduce cytotoxicity of poly (lactic acid) nanoparticles in a high-content screening assay

The objective of this study was to evaluate the cytotoxicity of poly (lactic acid) (PLA) nanoparticles. We used a water-soluble, amphiphilic phospholipid polymer, poly (2-methacryloyloxyethyl phosphorylcholine-co-n-butyl methacrylate) (PMB30W), as a stabilizer for the PLA nanoparticles. The PLA nanoparticles and PMB30W-modified PLA (PLA/PMB30W) nanoparticles were prepared by evaporating tetrahydrofuran (THF) from its aqueous solution. Precipitation of the polymers from the aqueous solution produced PLA and PLA/PMB30W nanoparticles with a size distribution of 0.4-0.5 μm. The partial coverage of PMB30W on the surface of the PLA/PMB30W nanoparticles was confirmed by X-ray photoelectron spectroscopy (XPS) and dynamic light-scattering (DLS). A high-content automated screening assay (240 random fields per group) revealed that the PLA nanoparticles induced apoptosis in a mouse macrophage-like cell line (apoptotic population: 73.9% in 0.8 mg PLA/mL), while the PLA/PMB30W nanoparticles remained relatively non-hazardous in vitro (apoptotic population: 13.8% in 0.8 mg PLA/mL). The reduction of the apoptotic population was attributed to the phosphorylcholine groups in the PMB30W bound to the surface of the nanoparticle. In conclusion, precipitation of PLA in THF aqueous solution enabled the preparation of PLA nanoparticles with similar shapes and size distribution but different surface characteristics. PMB30W was an effective stabilizer and surface modifier, which reduced the cytotoxicity of PLA nanoparticles by enabling their avoidance of the mononuclear phagocyte system.
Identifying functional site of disordered proteins

Molecular recognition features (MoRFs) has been proved to play critical role in molecular-interaction network of the cell, especially in eukaryotes. They act as molecular switches in the processes of cell signaling and regulation, and have relationship with the cause of many diseases. The importance of identifying MoRFs in disordered proteins is becoming increasingly apparent. However, due to unique structural and particular physiochemical properties of disordered proteins, traditional methods used for identifying functional sites of ordered proteins are ineffective for predicting MoRFs in disordered proteins. In this study, we propose a novel method, using a masking encoding scheme which extracts the relatively conservative information of residues for prediction. We compared our method with 9 other existing methods on a same test-dataset; the experimental results showed that, our method achieved the best performance, which got an AUC of 0.758. This study demonstrated that: 1) the flanking regions of MoRFs affected the plasticity of MoRFs; 2) MoRFs were flanked by less conserved residues; and 3) the masked and filtered PSSM was predictive features for identifying MoRFs． Keyword MoRFs，disordered proteins，PSSM
The Dynamics of Food Stamp Program Participation: A Lagged Dependent Variable Approach

This paper investigates the existence of Food Stamp Program (FSP) participation state dependence and its sources in by analyzing the dynamics of participation in the FSP using a lagged dependent variable approach. Results show that FSP receipt in the previous year is an important determinant of current FSP receipt. However, estimated persistence rates declined significantly after 1996, suggesting that long-term FSP dependency was reduced following broader welfare reform measures. The source of FSP state dependence among low-income households is mostly structural implying that a welfare trap does exist.
Multi-physical modeling and experimental verification of a respiratory system

This report describes the dynamic and steady-state modeling of a respiratory device in the multiphysical domain. The multi-physical domain covers the electrical, the (electro)mechanical and pneumatic components of the system. The electromechanical parts are simulated using lumped parameter analysis. These electromechanical parts consists of an inverter and a permanent magnet synchronous motor. Several parameters can not be derived directly from the specifications. Therefore, several additional (semi-)analytical models are derived. The electromechanical developed torque and the back-EMF constant are calculated by means of Fourier series. The selfand mutual inductance are derived by means of the Biot-Savart law. These models are verified by means of 2D FEM models and by means of measurements. The dynamics of the pneumatic system are analyzed using the lumped parameter Greitzermodel. The model-parameters are derived by means of the measured surge-frequency. The steadystate performance of the pneumatic system is described by a compressor map. An analytical relation is derived to describe the compressor map, which is inverted to improve the implemented control action. One general model is obtained by coupling the models of the different parts of the multiphysical domain. Experiments are carried out to verify all the models, including the dynamics and steady-state characteristics. Using the models, the efficiency of the respiratory system with the implemented driving strategy is derived. To improve the calculated system efficiency an alternative strategy is proposed.
The Effect of Hydromorphological Changes on Habitat Composition of the Szigetköz Floodplain

Impacts of river engineering, particularly effects of channelisation were studied by analysis of historical maps from the early 19th century in the Szigetkoz floodplain of the Danube River. Different hydrogeomorphological situations were investigated at a study site (Bodaki-branch system), where several deficiencies of altered river ecosystems (areal decline of aquatic habitats, change of bed load transport, decrease of lateral river-floodplain connectivity, etc.) can be recognised. Prior to extensive regulations, the Szigetkoz floodplain was a highly dynamic braided and anabranching channel system. Alteration of the hydrogeomorphological processes by engineering lead to aggradation of river-floodplain ecosystem, formation of several abandoned channels and significant decline of the ecological rejuvenation of the aquatic habitats. Our results indicate long-term changes of landscape dynamics and fragmentation of the river ecosystem from the pre-regulation period up to the present situation.
Tai Chi improves pain and functional status in adults with rheumatoid arthritis: results of a pilot single-blinded randomized controlled trial.

BACKGROUND/AIMS Rheumatoid arthritis (RA) is a serious health problem resulting in significant morbidity and disability. Tai Chi may be beneficial to patients with RA as a result of effects on muscle strength and 'mind-body' interactions. To obtain preliminary data on the effects of Tai Chi on RA, we conducted a pilot randomized controlled trial. Twenty patients with functional class I or II RA were randomly assigned to Tai Chi or attention control in twice-weekly sessions for 12 weeks. The American College of Rheumatology (ACR) 20 response criterion, functional capacity, health-related quality of life and the depression index were assessed. RESULTS At 12 weeks, 5/10 patients (50%) randomized to Tai Chi achieved an ACR 20% response compared with 0/10 (0%) in the control (p = 0.03). Tai Chi had greater improvement in the disability index (p = 0.01), vitality subscale of the Medical Outcome Study Short Form 36 (p = 0.01) and the depression index (p = 0.003). Similar trends to improvement were also observed for disease activity, functional capacity and health-related quality of life. No adverse events were observed and no patients withdrew from the study. CONCLUSION Tai Chi appears safe and may be beneficial for functional class I or II RA. These promising results warrant further investigation into the potential complementary role of Tai Chi for treatment of RA.
A Defective Interfering RNA Molecule in Cymbidium Ringspot Virus Infections

Summary A small RNA (DI RNA), approx. 400 bp in length, was found in plants inoculated with cymbidium ringspot tombusvirus (CyRSV). DI RNA contained sequences derived from at least three regions of the CyRSV genome and was encapsidated in CyRSV protein. DI RNA was formed in plants inoculated with purified genome-size RNA and a double-stranded form was detected in dsRNA extracted from infected tissue. Symptoms of CyRSV infection in Nicotiana clevelandii were less severe when DI RNA was present in the inocula used suggesting that DI RNA interferes with symptom expression.
