Published: September 2021

Abstract
Cricket-bowling performance is known to be influenced by speed of ball release and accuracy. Currently, training sessions typically involve fielding-specific drills and conditioning exercises. Scientific evidence for inclusion of a comprehensive yoga intervention in daily training and exercise sessions remains unexplored. The present study explored the effect of yoga on bowling performance and physical fitness in cricket bowlers. Sports fitness testing and training were conducted among 60 non-elite recreational-club male cricket players aged 13–25 years. Cricket-bowling speed was e valuated using a speed radar gun, accuracy with a test developed by Portus et al., cardiorespiratory endurance using the yo-yo intermittent recovery test, lower-extremity and trunk strength using a back-leg dynamometer, upper-limb power using a medicine ball–throw test, power using a vertical-jump test, and flexibility using a sit-and-reach test. In addition to bowling practice, the yoga intervention group (n = 30) performed pranayama and standing and prone asana, whereas the control group (n = 30) practiced conventional conditioning exercises, for 45 minutes/day, three times a week, for 12 weeks. Improvement in bowling speed, accuracy, cardiorespiratory endurance, muscle strength, and flexibility were comparable between the two groups. Statistically significant improvements in baseline scores in bowling speed, accuracy, cardiorespiratory endurance, muscle flexibility, strength, and power were comparable between the two groups of non-elite male cricket players. Bowling speed improved by 6.52% in the yoga group and by 5.18% in the control group. Bowling accuracy improved by 35.40% in the yoga group and by 31.29% in the control group. Additional research on long-duration intervention in elite players may help to establish the role of yoga in conventional cricket-bowling training.

Published: September 2021

Purpose: The aim of the present study was to evaluate survivin immunoexpression and the clinicopathologic correlations in serous borderline ovarian tumors (BOT) patients ≤ 40 years old.
Materials and Methods: A total of 36 BOT cases were evaluated. After excluding the mucinous type and patients over 40 years of age, 20 serous BOT cases meeting the criteria were included. A similar number of benign ovarian cysts and 20 serous malign ovarian tumors were randomly included as the control group. The patients were then staged based on their surgical findings and 2014 FIGO criteria, and their histological tumor types obtained from pathological specimens were determined using WHO criteria. The survivin levels in the specimens were analyzed using immunohistochemical assays.
Results: Positive survivin expression was detected in 10% of benign tumors, 100% of serous BOTs, and 100% of serous malign ovarian tumors. Mean survivin immunoreactivity was statistically similar between groups and it was found to be significantly higher in both groups compared to the control group. Survivin expression was positively correlated with FIGO stage, tumor grade, microinvasion, and micropapillary pattern.
Conclusion: Survivin immunoexpression is correlated with the malignancy potential of serous BOTs, and that survivin immune expression may be a histopathological marker that will help in making a decision on fertility-sparing surgery and follow upin young patients.

abstract
Seismic moments Mo and local magnitudes ML for earthquakes near Oroville, California imply the linear log seismic moment-local magnitude relation
log ⁡ 10 ( M o ) = ( 1.21 ± 0.03 ) M L + ( 17.02 ± 0.07 ) for 17 &lt; log 10 M o &lt; 25.
Coda durations τ for short-period, vertical-component seismographs located in the epicentral region are related to local magnitude using two linear log τ-ML segments with point of intersection at ML ≂ 1.5. The rms error is 0.1 to 0.2 units of magnitude. A relation of the form log Mo = a1 + a3 (log τ)2 is sufficient (in the sense that rms error in log10Mo is 0.2 to 0.3 units) to relate τ and Mo for 18 ≦ log10Mo &lt; 22. Coefficients for the above τ-ML and τ-Mo relationships are established for three seismographs of differing response
Lateral inhomogeneities in P velocity under the Tarbela array of the lesser Himalayas of Pakistan
Authors: Menke William H. 
Published: September 2021

abstract
Three-dimensional seismic-velocity heterogeneities (to a depth of 125 km) under the Tarbela array are determined by the Aki et al. (1976a) method of inverting teleseismic travel-time residuals. Velocity anomalies are clearly present and are elongated in the northwest direction. An overall 2 to 3 per cent decrease in velocity to the northeast is observed across any horizontal layer. These features result from a 4° dip of geologic structures in the direction N41°E. This direction is similar to some observed trends of seismicity in the Tarbela area and to the trend of the Himalayan Main Central Thrust (MCT) east and north of Tarbela, but not to the trend of the fault traces nor the strike of geologic structures in the Tarbela area. Just to the southeast of the Tarbela array, these faults bend sharply westward, forming a mountainous loop. In this study it is concluded that the westerly trending fault traces and westerly striking geology are both only surficial and not representative of structures at greater depth. These deep structures within the lower crust and upper mantle preserve a strike similar to more eastern areas along the MCT. They are shown to be volumetrically and tectonically the more important features.
Truncated exponential frequency-magnitude relationship in earthquake statistics
Authors: Cosentino P. , Ficarra V. , Luzio D. 
Published: September 2021

abstract
The following doubly truncated exponential probability density distribution
f ( M ) = β exp ⁡ { − β ( M − M 0 ) } / { 1 − exp ⁡ { − β ( M p − M 0 ) } } for M 0 ≦ M ≦ M p f ( M ) = 0 for M ≧ M p , ( a )
where M0 is the threshold magnitude value, and β is a parameter, is proposed for the earthquake occurrence. The relation (a) has been obtained carrying out a simple model based on a number of assumptions, among which the more characterizing is the existence of a maximum regional finite magnitude value Mp. This assumption, derived by an evidence recognized by most seismologists, allows a simple explanation of the known behavior of the experimental cumulative frequency-magnitude graphs.
In order to estimate β and Mp the moments method is suggested, which also represents a maximum likelihood method for β estimation.
Finally, some results of application of the model to six seismic regions are presented.
Numerical seismograms for a vertical point-force in a layered solid
Authors: Abramovici F. , Gal-Ezer J. 
Published: September 2021

abstract
The vertical and horizontal displacements of a solid made up of one layer over a half-space, due to the presence of a vertical point-force acting beneath or at the free surface are calculated using a synthetic generalized ray expansion. Each term in the expansion represents a group of rays reflected the same number of times as P and S. The time dependence of the applied force at the source is a triangular function. Seismograms corresponding to the source term and for a half-space are also shown.
The behavior of the displacements is determined by the S-wave part of the motion. Some rays are clearly distinguishable, like the direct P or some of those following a totally reflected ray of the same type, like SP or SSP (denoted S2P). Also very prominent are the rays of type Sn arriving after diffracted ones at the free surface. It turns out, however, that the appearance of many portions of the seismograms is the result of the superposition of several generalized rays, contributing not only at their arrival but also later, at subsequent times.
The amplitude ratio of the P and S arrivals is shown to be related to the time dependence of the source: S appears to have a larger amplitude than P for short-duration sources.
Long-period reflected and converted upper-mantle phases
Authors: Ward Steven N. 
Published: September 2021

abstract
Record sections of long-period seismograms from shallow-focus events at distances between 80° and 120° commonly display significant amounts of spatially coherent energy between the arrivals of P and PP. While individual quality varies, the majority of observations share two characteristics: coherent arrivals have apparent ray parameters and amplitude attenuation rates more comparable to P than PP. The ray-kinematic restraints imposed by these statements suggest wave interactions in the upper mantle near the source or receiver. The dynamics of these phases are investigated by construction of synthetic seismograms for radially symmetric media by contour integration in the complex ray-parameter plane. The generated records containing contributions from waves reflected or converted at upper mantle discontinuities are found to be compatible with observations. The largest of these coda phases on vertical records are near-source-shear converted compressional waves of the types sdP and sdpP. Conjugate near-receiver phases are of less importance than near-source phases on vertical records but they can be expected to dominate on the horizontal component. The effect of transition zone thickness on these phases is determined by direct integration of the equations of motion. For a 10-km-thick transition, reflected amplitudes become negligibly small for waves with periods less than 3 sec. Transmitted converted waves, on the other hand, have significant amplitudes to periods as small as 1 sec. In the long-period passband, peaked near 15 sec, the transition behaves as a sharp interface. These signals are found to be highly sensitive to localized upper mantle structure. Further observations of these phases will provide a direct means of assessing the physical and regional extent of the discontinuities throughout the Earth.
Time-domain observation and synthesis of split spheroidal and torsional free oscillations of the 1960 chilean earthquake: Preliminary results
Authors: Stein Seth , Geller Robert J. 
Published: September 2021

AbstractThe rotationally and elliptically split normal modes of the earth are observed for the 1960 Chilean earthquake by analysis in the time domain. One hundred and fifty hours of the Isabella, California, strain record are narrow band filtered about the central frequency of each split multiplet to isolate the complex wave form resulting from the interference of the different singlets. We compute synthetic seismograms using our previous theoretical results, which show the dependence of the amplitude and phase of the singlets on source location, depth, mechanism, and the position of the receiver. By comparing these synthetics to the filtered record, we conclusively demonstrate the splitting of modes whose splitting had not been definitely resolved: torsional modes (0T3, 0T4) and spheroidal modes (0S4, 0S5). The splitting of 0S2 and 0S3 is reconfirmed. We obtain good agreement between the synthetics and the filtered data for a source mechanism (previously determined from long-period surface waves) of thrust motion on a shallow dipping fault.

Human teeth as a reliable age marker: A study on migrant labour population
Authors: Anand Anupama J , Shankar Anand 
Published: September 2021

Age is one among the factors which is supposed to be identified in establishing identity of an unknown or deceased person. It is found to be more reliable and accurate to determine the age of a person. The determination of age can be achieved from various physical markers present in body, this includes teeth, bones, and skull. There is certain age where the long bones tend to complete their growth, the growth of skull is well marked by the time of order of their suture closures. A well-developed cranial bone depicts that it is intersected with a suture. besides the bone and skull another reliable physical marker is the human teeth, teeth is considered to be the hardest tissue in humans which is not affected by the factors such as heat, temperature, moisture etc. it is an effective identifier in cases of mass disaster where it is practically impossible to determine the identity of the person through the bones available from the crime site. Teeth is a very important factor to determine the age in disputed cases. Since the age can be estimated even from skeletal remains, teeth are preferred for estimation in certain cases as it is considered to be one among the hardest tissues of the human body. Teeth has got a very unique feature as it cannot be destroyed by heat or any thermal factors or other environmental factors. This property of the teeth has to be effectively utilized for age estimation. The following study was conducted on migrant workers working on a peeling company, the purpose behind the study is to determine whether all the workers have 18 years of age and to ensure that no or none of them are working below the age of 18. There are certain cases reporting that some of these workers have found committing impersonating forgery claiming to be above 18 years of age. The study is specifically to find the age of workers by examining the teeth and also to find if any forgery is done or not. This study was also done to check whether labor laws has been violated or not in accordance with the Constitution of India, no child below the age fourteen years of age shall be employed to work in any factory or mine or engaged in any other hazardous employment, therefore employment of a child under the age of 14 years is punishable by law (child labor prohibition and regulation act of 2012). The need of the study arises from this very fact that the proof of age is not an authenticated document. With repeated reports of forgery regarding the proof of age, submitting ration card as proof of age. And in the wake of current scenarios to ensure that no child is exploited in any kind of ways. The study was done on migrant labor population working in a factory and the estimation is carried out using the Demirjian method along with Acharya’s India specific value and the probable age of the respondents are calculated.
