Abstract:

Revenue from dairy farms is directly dependent upon reproductive efficiency because it affects milk production and the number of calves born (Thurmond et al., 1990). Pregnancy loss can have devastating effects on economical success in dairy farms. Normal annual abortion risks have been cited to be 3–5%, once cows are beyond 42 days of pregnancy (Hovingh, 2002), or similarly an observable 2–5% in most dairies (Kirk, 2003). Although, there is little or no indication that milk production is a risk factor for increased pregnancy losses in dairy cattle (Santos et al., 2004), there is little information on the effect of pregnancy losses on subsequent milk production. The aim of this study was to evaluate the impact of different calving classes including eutocia, dystocia, stillbirth and abortion in the first calving on subsequent milk production in Iranian Holstein dairy cows.

Abstract:

With the development of electronic technology, the electronic threats faced by microwave semiconductor devices was increasingly serious.In order to study the electrostatic discharge damage mechanism of bipolar silicon transistors, this paper analyzed the basic physical characteristics of bipolar transistor in electrostatic discharge, such as kirk effect and current crowding effect. Through analysis the human body electrostatic discharge model, established the ESD electric injury model of bipolar silicon transistor. If we knew the production process parameter of devices, we can calculate the ESD damage threshold for designing bipolar silicon device and providing a theoretical basis of parameter optimization. Finally the common ESD damage criterion were analyzed from different angles.

Abstract:

Phosphatidylinosital-4,5-bisphosphate (PIP2) acts as an essential factor regulating the activity of all Kir channels. In most Kir members, the dependence on PIP2 is modulated by other factors, such as protein kinases (in Kir1), Gβγ (in Kir3), and the sulfonylurea receptor (in Kir6). So far, however, no regulator has been identified in Kir2 channels. Here we show that polyamines, which cause inward rectification by selectively blocking outward current, also regulate the interaction of PIP2 with Kir2.1 channels to maintain channel availability. Using spermine and diamines as polyamine analogs, we demonstrate that both spontaneous and PIP2 antibody–induced rundown of Kir2.1 channels in excised inside-out patches was markedly slowed by long polyamines; in contrast, polyamines with shorter chain length were ineffective. In K188Q mutant channels, which have a low PIP2 affinity, application PIP2 (10 μM) was unable to activate channel activity in the absence of polyamines, but markedly activated channels in the presence of long diamines. Using neomycin as a measure of PIP2 affinity, we found that long polyamines were capable of strengthening either the wild type or K188Q channels' interaction with PIP2. The negatively charged D172 residue inside the transmembrane pore region was critical for the shift of channel–PIP2 binding affinity by long polyamines. Sustained pore block by polyamines was neither sufficient nor necessary for this effect. We conclude that long polyamines serve a dual role as both blockers and coactivators (with PIP2) of Kir2.1 channels.

Abstract:

Purpose This study evaluated the relationship between working memory (WM) and speech recognition in noise with different noise types as well as in the presence of visual cues. Method Seventy-six adults with bilateral, mild to moderately severe sensorineural hearing loss (mean age: 69 years) participated. Using a cross-sectional design, 2 measures of WM were taken: a reading span measure, and Word Auditory Recognition and Recall Measure (Smith, Pichora-Fuller, & Alexander, 2016). Speech recognition was measured with the Multi-Modal Lexical Sentence Test for Adults (Kirk et al., 2012) in steady-state noise and 4-talker babble, with and without visual cues. Testing was under unaided conditions. Results A linear mixed model revealed visual cues and pure-tone average as the only significant predictors of Multi-Modal Lexical Sentence Test outcomes. Neither WM measure nor noise type showed a significant effect. Conclusion The contribution of WM in explaining unaided speech recognition in noise was negligible and not influenced by noise type or visual cues. We anticipate that with audibility partially restored by hearing aids, the effects of WM will increase. For clinical practice to be affected, more significant effect sizes are needed.

Abstract:

Purpose The goal of this study was to determine whether hearing aids in combination with computer-based auditory training improve audiovisual (AV) performance compared with the use of hearing aids alone. Method Twenty-four participants were randomized into an experimental group (hearing aids plus ReadMyQuips [RMQ] training) and a control group (hearing aids only). The Multimodal Lexical Sentence Test for Adults (Kirk et al., 2012) was used to measure auditory-only (AO) and AV speech perception performance at three signal-to-noise ratios (SNRs). Participants were tested at the time of hearing aid fitting (pretest), after 4 weeks of hearing aid use (posttest I), and again after 4 weeks of RMQ training (posttest II). Results Results did not reveal an effect of training. As expected, interactions were found between (a) modality (AO vs. AV) and SNR and (b) test (pretest vs. posttests) and SNR. Conclusion Data do not show a significant effect of RMQ training on AO or AV performance as measured using the Multimodal Lexical Sentence Test for Adults.

Abstract:

The study determined the effect of Humanistic-Existential Therapy (HET) on self-control of rehabilitated female sex workers in Osun State and investigated the effect of demographic variables on the effectiveness of HET on the workers. The study adopted the pretest-posttest, control group quasi-experimental research design. The population comprised rehabilitated female sex workers who visited the Living Hope Care at Ilesa regularly for medical and sex guidance. The sample comprised 64 rehabilitated female sex workers selected from brothels in Osun State using purposive and convenient sampling techniques. The HET of Kirk Schneider (2008) treatment package used; while the Tangney, Baumeister, and Boone (2004) self-control was used. Data collected were analysed using percentage, counts, and Analysis of Covariance (ANCOVA).The results showed a significant effect of humanistic-existential therapy on the self-control of the participants at (F= 28.772, df =1, p-value =0.000). It further showed the respondents’ age (F= 1.229, df =5, p-value =0.35), family background (F= 2.152, df =1, p-value =0.166); while marital status (F= 2.82, df =4, p-value =0.069) had no significant simple moderating effect on the effectiveness of HET on the self-control of the participants. The study concluded that Humanistic-Existential Therapy was effective in treating self-control of the rehabilitated female sex workers.

Abstract:

This comment reassesses the prominent claim from Desmond, Papachristos, and Kirk (2016) (DPK) that 911 calls plummeted—and homicides surged—because of a police brutality story in Milwaukee (the Jude story). The results in DPK depend on a substantial outlier 47 weeks after the Jude story, the final week of data. Identical analyses without the outlier final week show that the Jude story had no statistically significant effect on either total 911 calls or violent crime 911 calls. Modeling choices that do not extrapolate from data many weeks after the Jude story—including an event study and “regression discontinuity in time”—also find no evidence that calls declined, a consistent result across predominantly black neighborhoods, predominantly white neighborhoods, and citywide. Finally, plotting the raw data demonstrates stable 911 calls in the weeks around the Jude story. Overall, the existing empirical evidence does not support the theory that publishing brutality stories decreases crime reporting and increases murders.

Full text

Abstract:

Crassula helmsii (T. Kirk) Cockayne is an invasive aquatic plant in Europe that can suppress many native species because it can grow at a large range of dissolved inorganic carbon concentrations and light levels. One reason for its ecological success may be the possession of a regulated Crassulacean Acid Metabolism (CAM), which allows aquatic macrophytes to take up CO2 in the night in addition to the daytime. The effect of light and CO2 on the regulation of CAM and photosynthesis in C. helmsii was investigated to characterise how physiological acclimation may confer this ecological flexibility. After 3 weeks of growth at high light (230 µmol photon m–2 s–1), C. helmsii displayed 2.8 times higher CAM at low compared with high CO2 (22 v. 230 mmol m–3). CAM was absent in plants grown at low light (23 µmol photon m–2 s–1) at both CO2 concentrations. The observed regulation patterns are consistent with CAM acting as a carbon conserving mechanism. For C. helmsii grown at high light and low CO2, mean photosynthetic rates were relatively high at low concentrations of CO2 and were on average 80 and 102 µmol O2 g–1 DW h–1 at CO2 concentrations of 3 and 22 mmol m–3 CO2, which, together with mean final pH values of 9.01 in the pH drift, indicate a low CO2 compensation point (<3 mmol m–3) but do not indicate use of bicarbonate as an additional source of exogenous inorganic carbon. The relatively high photosynthetic rates during the entire daytime were caused by internally derived CAM-CO2 and uptake from the external medium. During decarboxylation, CO2 generated from CAM contributed up to 29% to photosynthesis, whereas over a day the contribution to the carbon balance was ≤13%. The flexible adjustment of CAM and the ability to maintain photosynthesis at very low external CO2 concentrations, partly by making use of internally generated CO2 via CAM, may contribute to the broad ecological niche of C. helmsii.

Abstract:

This research is aimed to examine the influence of Leadership styles and Organizational culture to Job Satisfaction. It is also to study the effect of Job Satisfaction to Organizational Commitment and to test the Cultural Organization, Leadership Styles, and Job Satisfaction toward Employee's Performance using Organizational Commitment as intervening variable. The use of these variables are based on the previous research by Koesmono (2005), Kirk L. Rogga (2001), Yuwalliatin (2006), Masrukhin & Waridin (2006), Morrison (1997), Samad (2005), Shea, M. (1999) dan Lok, Peter (2004) which found the direct effect and indirect effect of Organizational Culture, Leadership Style toward Job Satisfaction, Job Satisfaction toward Organizational Commitment, and Organization Culture, Leadership Style and job satisfaction toward Employee's performance using Organizational Commitment to be variabel interverning. Theses variables enable us to solve problems in PT. Garda Jakarta. The sample of this research was 100 employees of PT. Garda Jakarta. Structural Equation Model (SEM) was run by AMOS software to analyze data. The result showedthat Leadership Styles and Cultural Organization gives positive significant influence to JobSatisfaction, Job Satisfaction gives significant influence to Organizational Commitment, Organization Culture gives significant influence to Employee's performance, leadership style gives influence to Employee's Performance, Organization Culture, Leadership Style, and Job Satisfaction contributes an significant influence to Employee's Performance using Organizational Commitment to be variabel interverning. This empirical result indicates that Leadership Styles and Organizational Commitment become one of many causes that trigger low Employee's Performance Job Satisfaction, and Cultural Organization. The company needs to consider Leadership Styles, Organizational Commitment in order to increase Employee's Performance because those factors proved depend on them. Theoritical implications and suggestions for future research have been elaborated at the end of this study.

Abstract:

The cystic fibrosis transmembrane conductance regulator (CFTR) is an epithelial cell Cl channel, whose gating activity and membrane trafficking are controlled by cAMP/protein kinase A (PKA)-mediated phosphorylation. CFTR Cl currents are regulated also by syntaxin 1A (A. P. Naren, D. J. Nelson, W. W. Xie, B. Jovov, J. Pevsner, M. K. Bennett, D. J. Benos, M. W. Quick, and K. L. Kirk. Nature 390: 302–305, 1997), a protein best known for its role in membrane trafficking and neurosecretion. To examine the mechanism of syntaxin 1A inhibition, we expressed these proteins in Xenopusoocytes and monitored agonist-induced changes in plasma membrane capacitance and cell surface fluorescence of CFTR that contains an external epitope tag. cAMP stimulation elicited large increases in membrane capacitance and in cell surface labeling of flag-tagged CFTR. Coexpression of CFTR with syntaxin 1A, but not syntaxin 3, inhibited cAMP-induced increases in membrane capacitance and plasma membrane CFTR content. Injection of botulinum toxin/C1 rapidly reversed syntaxin’s effects on current and capacitance, indicating that they cannot be explained by an effect on CFTR synthesis. Functional expression of other integral membrane proteins, including Na-coupled glucose transporter hSGLT1, inwardly rectified K channel hIK1, P2Y2 nucleotide receptor, and viral hemagglutinin protein, was not affected by syntaxin 1A coexpression. These findings indicate that acute regulation of the number of CFTR Cl channels in plasma membrane is one mechanism by which cAMP/PKA regulates Cl currents. Inhibition of plasma membrane CFTR content by syntaxin 1A is consistent with the concept that syntaxin and other components of the SNARE machinery are involved in regulated trafficking of CFTR.

Abstract:

ABSTRACT Nicotiana plumbaginifolia UBP1 is an hnRNP-like protein associated with the poly(A)+ RNA in the cell nucleus. Consistent with a role in pre-mRNA processing, overexpression of UBP1 in N. plumabaginifolia protoplasts enhances the splicing of suboptimal introns and increases the steady-state levels of reporter mRNAs, even intronless ones. The latter effect of UBP1 is promoter specific and appears to be due to UBP1 binding to the 3′ untranslated region (3′-UTR) and protecting the mRNA from exonucleolytic degradation (M. H. L. Lambermon, G. G. Simpson, D. A. Kirk, M. Hemmings-Mieszczak, U. Klahre, and W. Filipowicz, EMBO J. 19:1638-1649, 2000). To gain more insight into UBP1 function in pre-mRNA maturation, we characterized proteins interacting with N. plumbaginifolia UBP1 and one of its Arabidopsis thaliana counterparts, AtUBP1b, by using yeast two-hybrid screens and in vitro pull-down assays. Two proteins, UBP1-associated proteins 1a and 2a (UBA1a and UBA2a, respectively), were identified in A. thaliana. They are members of two novel families of plant-specific proteins containing RNA recognition motif-type RNA-binding domains. UBA1a and UBA2a are nuclear proteins, and their recombinant forms bind RNA with a specificity for oligouridylates in vitro. As with UBP1, transient overexpression of UBA1a in protoplasts increases the steady-state levels of reporter mRNAs in a promoter-dependent manner. Similarly, overexpression of UBA2a increases the levels of reporter mRNAs, but this effect is promoter independent. Unlike UBP1, neither UBA1a nor UBA2a stimulates pre-mRNA splicing. These and other data suggest that UBP1, UBA1a, and UBA2a may act as components of a complex recognizing U-rich sequences in plant 3′-UTRs and contributing to the stabilization of mRNAs in the nucleus.

Abstract:

Oei, Erwin, Thomas Kalb, Prarthana Beuria, Matthieu Allez, Atsushi Nakazawa, Miyuki Azuma, Michael Timony, Zanetta Stuart, Houchu Chen, and Kirk Sperber. Accessory cell function of airway epithelial cells.We previously demonstrated that airway epithelial cells (AECs) have many features of accessory cells, including expression of class II molecules CD80 and CD86 and functional Fcγ receptors. We have extended these studies to show that freshly isolated AECs have mRNA for cathepsins S, V, and H [proteases important in antigen (Ag) presentation], invariant chain, human leukocyte antigen (HLA)-DM-α and HLA-DM-β, and CLIP, an invariant chain breakdown product. A physiologically relevant Ag, ragweed, was colocalized with HLA-DR in AECs, and its uptake was increased by granulocyte-macrophage colony-stimulating factor and IFN-γ treatments, which had no effect on CD80 and CD86 expression. We demonstrate the presence of other costimulatory molecules, including B7h and B7-H1, on AECs and the increased expression of B7-H1 on AECs after treatment with granulocyte-macrophage colony-stimulating factor and IFN-γ. Finally, we compared T cell proliferation after allostimulation with AECs and dendritic cells (DCs). The precursor frequency of peripheral blood T cells responding to AECs was 0.264% compared with 0.55% for DCs. DCs stimulated CD45RO+, CD45RA+, CCR7+and CCR7−CD4+, and CD8+T cells, whereas AECs stimulated only CD45RO+, CD45RA−, CCR7−, CD4+, and CD8+T cells. There was no difference in cytokine production, type of memory T cells stimulated (effector vs. long-term memory), or apoptosis by T cells cocultured with AECs and DCs. The localization of AECs exposed to the external environment may make them important in the regulation of local immune responses.

Abstract:

We have augmented our previous studies [Storey, Shears, Kirk & Michell (1984) Nature (London) 312, 374-376] on the subcellular location and properties of Ins(1,4,5)P3 (inositol 1,4,5-trisphosphate) phosphatases in rat liver and human erythrocytes. We also investigate Ins(1,3,4)P3 (inositol 1,3,4-trisphosphate) metabolism by rat liver. Membrane-bound and cytosolic Ins(1,4,5)P3 phosphatases both attack the 5-phosphate. The membrane-bound enzyme is located on the inner face of the plasma membrane, and there is little or no activity associated with Golgi apparatus. Cytosolic Ins(1,4,5)P3 5-phosphatase (Mr 77,000) was separated by gel filtration from Ins(1,4)P2 (inositol 1,4-bisphosphate) and inositol 1-phosphate phosphatases (Mr 54,000). Ins(1,4,5)P3 5-phosphatase activity in hepatocytes was unaffected by treatment of the cells with insulin, vasopressin, glucagon or dibutyryl cyclic AMP. Ins(1,4,5)P3 5-phosphatase activity in cell homogenates was unaffected by changes in [Ca2+] from 0.1 to 2 microM. After centrifugation of a liver homogenate at 100,000 g, Ins(1,3,4)P3 phosphatase activity was largely confined to the supernatant. The sum of the activities in the supernatant and the pellet exceeded that in the original homogenate. When these fractions were recombined, Ins(1,3,4)P3 phosphatase activity was restored to that observed in unfractionated homogenate. Ins(1,3,4)P3 was produced from Ins(1,3,4,5)P4 (inositol 1,3,4,5-tetrakisphosphate) and was metabolized to a novel InsP2 that was the 3,4-isomer. Ins(1,3,4)P3 phosphatase activity was not changed by 50 mM-Li+ or 0.07 mM-Ins(1,4)P2 alone, but when added together these agents inhibited Ins(1,3,4)P3 metabolism. In Li+-treated and vasopressin-stimulated hepatocytes, Ins(1,4)P2 may reach concentrations sufficient to inhibit Ins(1,3,4)P3 metabolism, with little effect on Ins(1,4,5)P3 hydrolysis.

Abstract:

A sample of eighty-two karatists at the ages from ten to fourteen has been analyzed for a system of 25 variables (12 morphological, 12 basic motoric variables and 1 specific motoric variable) with the aim of establishing the effect of prediction system of morphological variables and a system of basic motoric variables on the criterion variable, i.e., the direct forward kick - mae geri. The obtained results showed that the system of morphological variables had a statistically significant effect on the execution of direct forward kick. Among the individual variables in the regression analysis body weight had the largest effect. The stepwise method showed that body height and weight had highest prediction values. Young karatists of high body height, with long extremities and increased weight, had better results in the execution of direct forward kick. The investigation of basic motoric variables used in the regression and stepwise analyses indicated that the endurance in half-squat with weight and standing jump had statistically significant effects on the efficiency of direct forward kick. Thus it was concluded that the speed of forward kick depends on the explosive and static strength of legs.

Abstract:

Four main proprioceptors monitor tibial position in the hindleg of the locust: the femoral chordotonal organ (FCO), the lump receptor, the suspensory ligament receptors and Brunner's organ. The influence of these proprioceptors on quantitative aspects of the kick motor programme has been investigated. The parameters measured were the duration of the initial flexion burst, the duration of co-activation of flexor and fast extensor tibiae (FETi) motoneurones, the number of FETi spikes during the co-activation, the interval between the kick and post-kick flexion, the number of FETi spikes occurring in this interval and the duration of post-kick flexion activity. The lump receptor and Brunner's organ have no detectable effect on any of these parameters. The FCO has highly significant effects on the duration of both initial flexion and post-kick flexion bursts, and on the number of FETi spikes occurring after the moment of tibial extension. The suspensory ligament receptors have significant effects upon the number of FETi spikes after the kick and the interval between the kick and the post-kick flexion. However, no proprioceptor had any influence upon the duration of co-activation or the number of FETi spikes during the co-activation. Thus, although elements of the kick motor programme preceding and following co-activation are strongly influenced by proprioceptors monitoring tibial position and movement, the co-activation stage, which is central to the effectiveness of the complete behaviour pattern, is not affected.

Abstract:

Using an ab initio method we analyze the mechanisms of the boron diffusion with emphasis on the role of the intrinsic interstitials. It is shown that the boron diffusion is dominated by a kick-out mechanism. The different effect of silicon and carbon interstitials gives rise to kinetic effects. A preference for a kick-in of the boron interstitial into the carbon lattice sites is found. Kinetic effects reported in co-implantation experiments and in-diffusion experiments are explained by our findings.

Abstract:

Here, a new approach for calculating the triggering drain bias at the onset of the kink effect, kink voltage, V kink , for PD SOI NMOS devices utilizing electron drift properties in the channel is given. This approach directly relates electron mobility in the channel to the kink effect and enables one to determine kink voltage knowing the device technology. It also gives the possibility for calculating mobility from the kink voltage. Theory is compared to the previously published experimental results and based on this match, the behavior of the kink voltage for PD SOI NMOS components for various technology parameters is predicted. Explanation for the appearance of the kink in the volt regime below the band gap of silicon is also given. From this consideration, design rules for PD SOI NMOS devices are derived in order to soothe the kink effect.

Abstract:

The effect brought by the I–V kink effect on large signal performance of AlGaN/GaN high electron mobility transistors (HEMTs) was investigated in this paper. An improved compact model was proposed to accurately characterize the I–V kink effect. The bias dependence of the I–V kink effect has also been taken into consideration. AlGaN/GaN HEMTs with different gate width were utilized to validate the proposed model. Built on the proposed model, the effect brought by the I–V kink effect on large signal performance has been studied. Results show that the I–V kink effect will lead to the degradation of characteristics, including output power, gain, and power-added efficiency at the saturation region. Furthermore, the influence of the I–V kink effect was found to be related with the input power and the static bias point in this work. The time domain waveform and AC dynamic load line were used for validation of results based on simulation. The consequences of this paper will be useful for the optimization of practical circuit design.

Abstract:

By the use of the first-principles method, based upon density functional theory, we investigated the effect of C upon the electronic structure of a kink on the ½[111](1¯10) edge dislocation in bcc iron. The results show that C has a tendency to segregate towards the kink. The structural energies of some atoms of interest in the kink with C are lower than those of corresponding atoms in the clean kink. Furthermore, the interactions between C and the neighboring Fe atoms are very strong due to the hybridization between the C 2p state and the Fe 3d4s4p states. We find that there exists some charge accumulations between C and the neighboring Fe atoms. The analysis of the electronic structure indicates that the introduction of C can stabilize the kink system and impede the sideways motion of the kink. The C induces a strong pinning effect on the ½[111](1¯10) edge dislocation and may result in solid solute hardening.
