Comparison between Iraqi Jenoubi heifers and bulls fed on date palm pollen to accelerate puberty and sexual maturit

The objective of the current study was to compare puberty and sexual maturity in Iraqi Jenoubi bulls and heifers that were fed date palm pollen (DPP) in their diets. Ten Jenoubi heifers and ten bulls, 6-month-old were divided randomly into two treatments: DPP treatment (T1) supplemented with 2 g of DPP/ head/day and control treatment (T2) was not supplemented with DPP. In heifers, the overall mean value of control group was significantly lower (27.53, 0.96 ng/ml and 9.44 pg/ml) than treatment group (70.42, 18.27 ng/ml and 19.16 pg/ml) for FSH, LH and estrogen, respectively in puberty period. Similar trend was noticed for hormone concentrations (FSH, LH, Estrogen and Testosterone) for bulls at puberty and maturity age. In bulls, T1 was significantly higher (155 and 212.5 kg) than control group (139.5 and 196 kg) for body weight in puberty and maturity age respectively, and in heifers T1 was significantly higher (150.33 and 206.66 kg) than control group (142 and 198.66 kg) for body weight in puberty and maturity age respectively, and same trend was observed for body condition score (BCS). It can be concluded that adding date palm pollen to ration of heifers and bulls accelerates puberty and maturity in heifers and bulls. But the acceleration in heifers was more than in bulls.
Double-Mode RR Lyrae Variables in the Globular Cluster M3

We present new B-band CCD photometry for five double-mode RR Lyrae (RRd) variables (V68, V79, V87, V99, and V166) in the globular cluster M3. The pulsational behavior of the RRd variables is described. V68 and V87 have been known as RRd variables since 1982, V79 was recently discovered as an RRd (Clement et al.), and our data have identified V99 and V166 as RRd variables (Corwin et al.). Earlier studies of V79 and V166 do not show double-mode behavior, which indicates that these stars have only recently become RRd stars. V166 changed its dominant pulsation mode from fundamental to first overtone in the interval 1992 to 1993. The candidate double-mode variables V28 and V126 do not exhibit clear RRd behavior in the 1992–1993 data.

Effects of forest structure and human influence on the call rate of owls in the Piedmont Forest of Northwestern Argentina

ABSTRACT Owls (Strigiformes) play an important ecological role as predators that structure and organize biological communities. Specialized owl species dependent on old-growth forests have suffered declines because of forest loss or degradation by human activities. Few studies have been conducted on Neotropical owls, especially in the Piedmont Forest of Northwestern Argentina. The scarcity of information on habitat requirements and the effect of human impacts preclude the establishment of conservation and management activities. The human footprint index (HFI) is a tool for mapping human impacts on biodiversity that is used at global and regional scales, based on the estimated and standardized contribution of different human impact variables (e.g. road networks, urban centers, agricultural land, etc.). The objectives of this work were to: 1) Determine the call rate of five owl species in the Piedmont Forest of Northwestern Argentina, 2) relate forest structure to the call rate of owl species, and 3) relate human footprint index to the call rate of owls. We placed 28 automatic recorders in the Piedmont Forest, in sites with low and high Human influence, and characterized the forest structure around each recorder within a circular plot of 25 m diameter. We obtained 241 vocalizations in 168 intervals of 2 h for Ferruginous pygmy owl (Glaucidium brasilianum), Tropical screech-owl (Megascops choliba), Black-banded owl (Ciccaba huhula), Spectacled owl (Pulsatrix perspicillata), and Buff-fronted owl (Aegolius harrisii). We found that for Tropical screech-owl live tree basal area had a positive and diameter at breast height standard deviation had a negative influence on call rate. While for Black-banded owl, the dead tree density had a positive and human footprint index >1 had a negative influence on call rate. For Spectacled owl, dead tree density and human footprint index >1 had a negative influence on call rate. We provide first insights into the effects of forest structure and human influence on the call rate of owls in the Piedmont Forest of Northwestern Argentina, information that may guide forest management guidelines and conservation strategies.
Probabilistic Causality and the Question of Transitivity

After clarifying the probabilistic conception of causality suggested by Good (1961-2), Suppes (1970), Cartwright (1979), and Skyrms (1980), we prove a sufficient condition for transitivity of causal chains. The bearing of these considerations on the units of selection problem in evolutionary theory and on the Newcomb paradox in decision theory is then discussed.
Distorted-wave calculations of electron impact ionisation in the Ni isonuclear sequence

Electron impact ionisation cross sections for Ni+, Ni3+, Ni5+, Ni6+, Ni7+, Ni8+, Ni12+, Ni14+, and Ni16+ are calculated in the distorted-wave approximation. These calculations include contributions from direct ionisation and inner-shell excitation followed by autoionisation. For Ni12+, Ni14+, and Ni16+ the authors report not only on ionisation cross sections from the ground states but also from the metastable states of these ions. The Delta n=0 inner-shell excitations of the type 3p to 3d do not contribute to the ionisation cross section for ions beyond Ni4+. Nevertheless, contributions from Delta n>or=1 inner-shell excitations can be significant, especially in the higher ionisation stages; for example, in the case of Ni16+, the excitation-autoionisation contributions enhance the total cross section by nearly a factor of 4 near threshold. Experimental cross section measurements exist for all ions reported here, except Ni16+.
Effects of a Science Intervention Program on Middle‐Grade Student Achievement and Attitudes

Science curriculum reform, the act of restructuring science curriculum, is advocated by major educational stakeholders in the nation for improving student science achievement and attitudes toward science. An approach for restructuring science curricula is to include science intervention programs in established curricula. For this study, the effectiveness of a science intervention program on science achievement and attitudes of middle-grade students attending a 5-week academic enrichment program was determined. Effective curricular components, as identified by relevant research studies, were incorporated in the intervention program. Those components included appropriate content, as designated by national standards and state-mandated instructional objectives for Georgia, and the learning cycle teaching procedure. A mixed-methodology research design was used. For the quantitative data, a criterion-referenced test and a survey measuring attitudes toward science were administered to the students at the beginning and end of the program. Correlational t-tests were conducted using pretest and posttest scores from the criterion-referenced test and pretest and posttest attitude survey scores. Students' science achievement (p < .001) and attitudes toward science (p < .05) were higher following participation in the science intervention program. Qualitative data, which included narrative descriptions of students' behaviors as recorded in a teacher-researcher daily log, supported the findings of the quantitative research. Results from the study provide implications for science curriculum reform.
Mesoscale Motion Fields Associated with a Slowly Moving GATE Convective Band

Abstract The structure of the convective band of 14 September in the dense GATE observing array is determined using wind and thermodynamic data primarily from multiple aircraft penetrations, which are well distributed in the vertical and in time. The well-defined mesoscale features in the line, which are 10–40 km in scale, quasi-two-dimensional, and persist for several hours, determine the distribution of the convective-scale features, which are 5 km or less in size, three-dimensional, not generally detectable for more than one flight leg. At the leading edge, a 30 km zone of strong ascent is computed from two-dimensional continuity. Here, lifting of the ambient air creates a favorable environment—not found elsewhere—for deep cumulonimbus clouds to develop. Their updrafts are weak, 2–4 m s−1 on the average. Behind the updraft zone, below 3–4 km, is a broad descent zone. It corresponds to the stratiform rain area, and has little convection, and some drying at lower levels. On the average, the mass flux by .
A practical Lagrangian method for relating scalar concentrations to source distributions in vegetation canopies

The transfer of scalar atmospheric constituents within vegetation canopies cannot be predicted from simple gradient-diffusion theory. To replace gradient-diffusion theory in this context, an analytic Lagrangian theory is developed which predicts the concentration field of a scalar atmospheric constituent emanating from a spatially extensive source in an inhomogeneous turbulent flow. In this ‘localized near-field’ theory, the mean scalar concentration C is expressed as the sum of a diffusive far-field contribution Cf which obeys gradient-diffusion theory, and a non-diffusive near-field contribution Cn which is calculated for each source element by assuming the turbulence to be locally homogeneous. It follows that Cf provides the large-scale background variation and Cn the detailed local structure of the C profile. The theory applies to both non-advective and advective situations. Comparison with random-flight predictions of C shows that the assumptions of the theory (which are exact in homogeneous turbulence) are adequate for inhomogeneous turbulence typical of real canopies. The random-flight predictions also show that vertical velocity skewness (not accounted for in the localized near-field theory but typically of order −0.5 to −1 in canopies) has only a small effect on C.
The classification of (3, 3, 3) trilinear forms.

In Chapter l, we state some general facts about determinant varieties and cuboids. A generic cuboid defines determinantal cubic curves £([/*), E(V*) and E(W*) (by taking the determinants of the three matrix representations) in P(t/*), P(F*) and P(PF*) respectively. In addition, we also have a dominant determinantal variety E(V*W*) in P(F* ® W*) whichprojects onto E(V*) and E(W*). The relation betweenE(V*)9 E(W*) and £(F* W*) is äs follows:
Molecular clouds in M31 and M33

In order to determine the properties of the molecular clouds in nearby spiral galaxies, 49 H II regions in M31 and 6 H II regions in M33 were observed using the J = 1 0 transition of CO. Of these, 17 were detected in M31 and two in M33. For the CO detection in M31, = 0.14 K, = 12.5 km s , and = 2.1 K km s . The two detections in M33, which are toward the giant H II regions NGC 604 and NGC 595, are somewhat weaker than the mean values for clouds in M31, neither T(/sub R/ nor V shows any gradient with galactic radius, but is a decreasing function of radius. The mean values of and are considerably larger than the values that would be obtained by extrapolating local giant molecular clouds to the distance of M31. It is suggested that most of the CO emission is from small clouds in the beam which overwhelm the emission from the giant molecular clouds. Some observational tests of this suggestion are proposed. Like the molecular clouds in the Milky Way, the giant molecular clouds in M31 appear to be tidally limited. Inmore » M33 the larger inclination angle would make the observed contribution from small molecular clouds less significant, which is consistent with the observations. « less
CCRL2 affects the sensitivity of myelodysplastic syndrome and secondary acute myeloid leukemia cells to azacitidine

Better understanding of the biology of resistance to DNA methyltransferase (DNMT) inhibitors is required to identify therapies that can improve their efficacy for patients with high-risk myelodysplastic syndrome (MDS). CCRL2 is an atypical chemokine receptor that is upregulated in CD34+ cells from MDS patients and induces proliferation of MDS and secondary acute myeloid leukemia (sAML) cells. In this study, we evaluated any role that CCRL2 may have in the regulation of pathways associated with poor response or resistance to DNMT inhibitors. We found that CCRL2 knockdown in TF-1 cells downregulated DNA methylation and PRC2 activity pathways and increased DNMT suppression by azacitidine in MDS/sAML cell lines (MDS92, MDS-L and TF-1). Consistently, CCRL2 deletion increased the sensitivity of these cells to azacitidine in vitro and the efficacy of azacitidine in an MDS-L xenograft model. Furthermore, CCRL2 overexpression in MDS-L and TF-1 cells decreased their sensitivity to azacitidine. Finally, CCRL2 levels were higher in CD34+ cells from MDS and MDS/myeloproliferative neoplasm patients with poor response to DNMT inhibitors. In conclusion, we demonstrated that CCRL2 modulates epigenetic regulatory pathways, particularly DNMT levels, and affects the sensitivity of MDS/sAML cells to azacitidine. These results support CCRL2 targeting as having therapeutic potential in MDS/sAML.
Metal Exposure-Related Welder’s Pneumoconiosis and Lung Function: A Cross-Sectional Study in a Container Factory of China

Long-term inhalation of welding fume at high exposure can cause welder’s pneumoconiosis, and metals in welding dust are associated with respiratory dysfunction. This cross-sectional study, which contains 384 Chinese male workers who were or had been working in a container factory, aimed to assess the potential risk of haemal and urinary metal content in welder’s pneumoconiosis. Further, we investigated their effects on lung function parameters. Metal content and lung function were measured using inductively coupled plasma–mass spectrometry (ICP-MS) and spirometer, respectively. The concentration and metal content of respirable dust as well as total dust were collected at this container factory. Lung function of cases with welder’s pneumoconiosis was significantly worse, as indicated by lower values of FVC, FVC% predicted, FEV1, FEV1% predicted, MEF25% predicted, and MMEF% predicted (p < 0.05). Results of logistic regression models showed that haemal Cr and Zn were risk factors of welder’s pneumoconiosis (OR = 4.98, 95%CI: 1.73–21.20, p = 0.009 for Cr; OR = 5.23, 95%CI: 1.56–41.08, p = 0.033 for Zn) after adjusted with age, BMI, working years, welding dust exposure years, and smoking status. Multiple linear regression models showed that several metals (haemal Cd and Pb; urinary Cd and Fe) were significantly associated with different lung function indices in the welder’s pneumoconiosis group. Compared to non-welders, welders were exposed to considerably higher levels of respirable dust, total dust, and six kinds of metals (p < 0.05). In conclusion, haemal Cr and Zn are positively related to welder’s pneumoconiosis. Meanwhile, Cd and Pb might worsen lung function in welder’s pneumoconiosis.
A Change of Tune: The Democratization of Market Mediation and Crossover Production in the U.S. Commercial Music Industry

This article examines whether intermediaries and consumers exert similar influence on producers’ boundary-spanning efforts. I propose that boundary spanning is primarily constrained by intermediaries specialized in the market, not by consumers. Consequently, producers are more likely to obscure boundaries when intermediaries’ power weakens. To test these ideas, I exploit a natural experiment that shifted the hitmaking power of genre-specific radio stations to general consumers and thus partially democratized the market mediation structure of the U.S. commercial music industry. The results indicate that after democratization occurred in 2012, record labels were more likely to introduce crossover offerings that incorporated features from other popular genres. Through mechanism triangulation efforts, I found that strategic reorientation, or producers’ attempt to appeal to a broader spectrum of consumers across genre lines, plausibly explains the crossover effect. This study highlights democratizing changes that dilute intermediaries’ influence as a novel explanation of why constraints on producers’ boundary decisions have weakened in some markets. The findings suggest that intermediaries’ and consumers’ expectations may diverge, acting as conflicting forces that organizations must carefully manage. Many organizations closely monitor intermediaries that are deemed influential, but their influence should not be taken for granted as marketplaces empower consumers and become more democratized.
Underwater audiogram of a Hawaiian monk seal (Monachus schauinslandi)

Underwater audiograms are available for a few pinnipeds from the families otariidae and phocidae, but little is known about hearing abilities in the monachid seals. A young male Hawaiian monk seal (Monachus schauinslandi) was trained at Sea Life Park on Oahu, Hawaii for an underwater hearing test using a go/no‐go response paradigm. Over a 6‐month period, auditory thresholds from 2 to 48 kHz were measured using an up/down staircase psychometric technique. The resulting audiogram shows a somewhat narrower hearing range than for other pinnipeds. The monk seal’s hearing was most sensitive (20 dB above maximum sensitivity) between 12 and 28 kHz. Below 8 kHz, the Hawaiian monk seal’s hearing was less sensitive than other pinnipeds measured. High‐frequency sensitivity dropped off sharply above 30 kHz, as has been reported for other otariids, Callorhinus and Zalophus. Phocid seals, Phoca hispida, P. groenlandica, and P. vitulina, have a broader hearing range with the upper limit near 60 kHz.
Elements of the microphysical structure of numerically simulated nonprecipitating stratocumulus

Abstract A set of 500 simulated trajectories and a simple parcel model are used to (i) evaluate the performance of a large eddy simulation model coupled to a detailed representation of the droplet spectrum (the LES-BM model) and (ii) gain insight into the microphysical structure of numerically simulated nonprecipitating stratocumulus. The LES-BM model reasonably reproduces many observed features of stratocumulus. The largest sources of error appear to be associated with limited vertical resolution, the neglect of gas kinetic effects and the inability of the model to properly represent mixing across cloud interfacial boundaries. The first two problems have simple remedies; for instance, a condensation–nucleation scheme is derived that includes gas–kinetic effects thus obviating the second problem. The third source of error poses a more vexing, and as yet unsolved, problem for models of the class described herein. Trajectories timescales are analyzed and in-cloud residence times are found to be, in the mean.
Studies on Vermicomposting of Sericultural Wastes: An Eco-Friendly Approach for Effective Management of Seri-Wastes

Vermicompost is one of the most essential and efficient organic manure commonly applied to the mulberry field in most the advance sericulture countries. Vermicompost is the one of the beneficial biotechnology is the bioconversion of organic waste into useful form. In the current experiment, soil treated with vermicompost of three different treatments viz., Cow dung + Seri-waste (T-1), Cow dung +Seri-waste (T-2) and Cow dung +Seri-waste + Rice straw (T-3) were recorded different parameters. After the application of different treatment of vermicompost the best recorded treatment as a T-as 6.7 pH. The moisture retention capacity was recorded as 52% in T-1 and 74% and 62% respectively in T-2 and T-3, with electric conductivity as 2-3ms/cm. The soil texture of soil treated with T-2 (Cow dung +Seri-waste) showed best input as 50% as compared to T-1 and least in T-3 as 40% and 35% respectively. Application of different treatment of vermicompost on soil recorded to be T-2 (Cow dung +Seri-waste) showed positive response and high availability of microorganisms that are beneficial for the mulberry plant. The germination percentage of seed of mulberry treated with different treatment was recorded to be highest of 90% in T-2 and root and shoot length of plant grown as 26cm and 12cm as compared to T-1 and T-3 as 19 cm and 8cm, 34cm and 10cm respectively. Similarly, the moisture percentage and moisture retention capacity of T-2 was recorded to be highest as 74.64% and 73.21% respectively. Therefore, the current experiment opens new avenues vermicompost substrate for promoting of by-product utilization seri-waste in sericulture. The resultant product could be utilized for agricultural and horticultural as well. The present results offer numerous scopes for further sustainable agriculture with special emphasis on sericulture industry.
Pairs of additive congruences to a large prime modulus

Abstract This paper is concerned with non-trivial solvability in p–adic integers, for relatively large primes p, of a pair of additive equations of degree k > 1: where the coefficients a1,…, an, b1,…, bn are rational integers. Our first theorem shows that the above equations have a non-trivial solution in p–adic integers if n > 4k and p > k6. The condition on n is best possible. The later part of the paper obtains further information for the particular case k = 5. specifically we show that when k = 5 the above equations have a non-trivial solution in p–adic integers (a) for all p > 3061 if n ≥ 21; (b) for all p execpt p = 5, 11 if n ≥ 26.
Bases of exponentials, sines and cosines in weighted spaces on a finite interval

We obtain a result concerning the basis property in a weighted space on an interval for a system of exponentials generated by the zeros of the Fourier transform of a function with singularities at the ends of the support interval . For an arbitrary we find a criterion for the basis property of the system in a weighted space on the interval and the systems of sines and cosines in a weighted space on the interval . The weight is everywhere a finite product of polynomial functions.
