The effect of Yasthimadhu Ghrita Pichu in Cervical Erosion - A Case Study
Cervical erosion is a physiological state after menarche; the columnar epithelium within the endocervical canal grows and everts exposing the glandular epithelium on the ecto-cervix. The exposed glandular epithelium is gradually replaced by squamous epithelium. Mostly occurs during child bearing age with the symptoms like vaginal discharge, itching, pelvic pain, post coital bleeding dyspareunia. If it is not treated properly leads to cervical cancer. This case study is of a female patient who complained of cervical erosion which was treated with Ayurvedic Stanika Chikitsa - Yonidhavana with Nimba Patra Prakshalana and Yastimadhu Ghrita Pichu for 7 days. In the present study, Pichu with Yashtimadhu Ghrita is proved to give good results in cervical erosion. Hence the clinical trial can be done in large number of patients to see further results
PG1004+130: Hybrid Morphology Source or a Restarted FRII? A uGMRT Polarimetric Investigation
We present here the polarization image of the hybrid morphology (HYMOR) and
broad-absorption line (BAL) quasar PG1004+130 at 694~MHz obtained with the
upgraded Giant Metrewave Radio Telescope (uGMRT). We detect linear polarization
in this source's core, jets, and lobes. The visible discontinuity in total
intensity between the inner jets and the kpc-scale lobes suggests that the
source is restarted. The inferred poloidal magnetic (B-) field structure in the
inner jet is consistent with that observed in Fanaroff-Riley (FR) type II
sources, as are the B-fields aligned with the lobe edges. Moreover, archival
Chandra and XMM-Newton data indicate that PG1004+130 displays several
FRII-jet-like properties in X-rays. We conclude that PG1004+130 is a restarted
quasar, with both episodes of activity being FRII type. The spectral index
images show the presence of an inverted spectrum core (),
a steep spectrum inner jet () surrounded by much steeper
lobe emission (), consistent with the suggestion that
the lobes are from a previous activity episode. The spectral age difference
between the two activity episodes is likely to be small (
years), in comparison to the lobe ages ( years). The
inferred B-fields in the lobes are suggestive of turbulence and the mixing of
plasma. This may account for the absence of X-ray cavities around this source,
similar to what is observed in M87's radio halo region. The depolarization
models reveal that thermal gas of mass M
is mixed with the non-thermal plasma in the lobes of PG1004+130.Comment: 14 pages, 5 figures, accepted for publication in The Astrophysical

Probing the Interplay between Jets, Winds, and Multi-phase Gas in 11 Radio-quiet PG Quasars: A uGMRT-VLA Study
\ua9 2023. The Author(s). Published by the American Astronomical Society. We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index, and polarization properties from the VLA study, coupled with the findings of our previous 685 MHz uGMRT data, we find the presence of low-power jets on subarcsecond and arcsecond scales in nine sources; some show signatures of bent jets. The origin of radio emission remains unclear in the remaining two sources. Of the 11 sources, linear polarization is detected in four of them with fractional polarization ranging between 2% and 21%. In PG 1229+204, the inferred B-field direction is parallel to the local kiloparsec-scale jet direction. The inferred B-fields are transverse to the weak southward extension in PG 0934+013. For PG 0050+124 and PG 0923+129, the relationship between the B-field structure and radio outflow direction remains unclear. Localized or small-scale jet-medium interactions can be inferred across the sample based on the VLA jet kinetic power arguments and polarization data. These may have the potential as a feedback mechanism. We find that the radio properties do not show strong correlations with the star formation, [O iii] and CO quantities published in the literature. The lack of evidence of AGN feedback on the global galaxy properties could be due to the relative timescales of AGN activity and those over which any impact might be taking place
Pengaruh Hubungan Interpersonal dan Lingkungan Kerja terhadap Kepuasan Kerja Guru di Sman 1 Kampar dan Sman 2 Kuok
The research was conducted on SMA N 1Kampar and SMAN 2 Kuok in order to determine the influence of interpersonal relationships and work environment on job satisfaction of teachers. The samples in this study were as many as 105 teachers consisting of 75 teachers in SMA N 1 Kampar and 30 teachers at SMAN 2 Kuok. The analytical tool used was a questionnaire. Simultaneous regression (F test) showed that the independent variables studied (interpersonal relationships and work environment) jointly (simultaneously) have a significant effect on the dependent variable (job satisfaction). The magnitude of the effect that (R2) by the two independent variables is the same bersmaa-28.2% of the dependent variable, while the remaining 77.20% is influenced by other variables not examined in this study. Partial regression test (t test) showed that interpersonal relationships and work environment has a significant effect on the dependent variable (job satisfaction). Dominant variable affecting job satisfaction in SMA N 1 Kampar and SMAN 2 Kuok is the interpersonal relationship where tcounted value of the highest compared with the other independent variables.Keywords: Interpersonal Relations, Work Environment and Job Satisfactio
A 9.38-bit, 422nW, high linear SAR-ADC for wireless implantable system
In wireless implantable systems (WIS) low power consumption and linearity are the most prominent performance metrics in data acquisition systems. successive approximation register-analog to digital converter (SAR-ADC) is used for data processing in WIS. In this research work, a 10-bit low power high linear SAR-ADC has been designed for WIS. The proposed SAR-ADC architecture is designed using the sample and hold (S/H) circuit consisting of a bootstrap circuit with a dummy switch. This SAR-ADC has a dynamic latch comparator, a split capacitance digital to analog converter (SC-DAC) with mismatch calibration, and a SAR using D-flipflop. This architecture is designed in 45 nm CMOS technology. This ADC reduces non-linearity errors and improve the output voltage swing due to the usage of a clock booster and dummy switch in the sample and hold. The calculated outcomes of the proposed SAR ADC display that with on-chip calibration an ENOB of 9.38 (bits), spurious free distortion ratio (SFDR) of 58.621 dB, and ± 0.2 LSB DNL and ± 0.4LSB INL after calibration
A Polarization Study of 3 Blazars using the uGMRT at ~600 MHz
We present results from our radio polarimetric study with the upgraded Giant
Metrewave Radio Telescope (uGMRT) at Band 4 (550-850 MHz) of 3 blazars:
radio-loud quasars 3C390.3, 4C71.07 and BL Lac object 1ES 2344+514. The aim of
this study was (i) to carry out a feasibility study for Band 4 polarization
with the uGMRT, and (ii) to compare and contrast the kpc-scale polarization
properties between the blazar sub-classes. We have detected linear polarization
in all the three sources. The degree of linear polarization in the cores of the
two quasars is higher than in the BL Lac object, consistent with similar
differences observed on parsec-scales in blazars. The highest fractional
polarization of 15% is observed in the hotspot region of 3C390.3, which also
shows extended polarized lobe structures. 1ES 2344+514 shows a core-halo
structure whereas 4C71.07 remains unresolved. A rotation of polarization
electric vectors along the northern hotspot of 3C390.3, and the core of 1ES
2344+514, suggest jet bending. Greater depolarization in the southern lobe of
3C390.3 compared to the northern lobe indicates the presence of the
`Laing-Garrington effect'. Multi-frequency uGMRT polarimetric data are underway
to study the kpc-scale rotation measures across these sources in order to look
for differences in the surrounding media.Comment: 13 pages, 6 figures, accepted by Journal of Astrophysics and

A Kpc-scale Radio Polarization Study of PG BL Lacs with the uGMRT
We present here uGMRT band 4 (~650MHz) polarization images of 8 BL~Lac
objects belonging to the Palomar-Green (PG) `blazar' sample. A large fraction
of the sources (~63%) reveal core-halo radio structures with most of the
polarization detected in the inner core-jet regions. PG1101+385 and PG2254+075
exhibit a `spine-sheath structure' in polarization. The core-halo and
`spine-sheath' structures are consistent with the Unified Scheme suggestion
that BL~Lacs are the pole-on beamed counterparts of Fanaroff-Riley (FR) type I
radio galaxies. PG1418+546 and PG0851+203 (OJ287) show the presence of terminal
hotspots similar to FR type II radio galaxies. They were also found to be
low-spectrally peaked BL Lacs, supportive of the `blazar envelope' scenario for
BL~Lacs and quasars. Fractional polarization ranges from 1-13% in the cores and
2-26% in the inner jets/lobes of the sample BL Lacs. Compared to the varied
radio morphology of quasars from the PG `blazar' sample, the BL~Lacs appear to
be less diverse. A comparison of the inferred core magnetic (B-) field
structures on arcsec- (kpc-) scales w.r.t. the Very Long Baseline
Interferometry (VLBI) jet direction does not reveal any preferred orientation,
suggesting that if large-scale ordered B-fields exist, they do so on scales
smaller than probed by the current observations. However, the presence of
polarized emission on arcsec-scales suggests that any mixing of thermal plasma
with the synchrotron emitting plasma is insufficient to fully depolarize the
emission via the internal depolarization process.Comment: 17 pages; 12 figures; MNRAS accepte
Probing the interplay between jets, winds and multi-phase gas in 11 radio-quiet PG Quasars: A uGMRT-VLA study
We present polarization-sensitive images from the Karl G. Jansky Very Large
Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio
morphology, spectral index and polarization properties from the VLA study,
coupled with the findings of our previous 685 MHz uGMRT data, we find the
presence of low-powered jets on sub-arcsecond and arcsecond scales in 9
sources; some show signatures of bent jets. The origin of radio emission
remains unclear in the remaining 2 sources. Of the 11 sources, linear
polarization is detected in four of them with fractional polarization ranging
between 2% and 25%. In PG 1229+204, the inferred B-field direction is parallel
to the local kpc-scale jet direction. The inferred B-fields are transverse to
the weak southward extension in PG 0934+013. For PG 0050+124 and PG 0923+129,
the relationship between the B-field structure and radio outflow direction
remains unclear. Localized or small-scale jet-medium interactions can be
inferred across the sample based on the VLA jet kinetic power arguments and
polarization data. These may have the potential as a feedback mechanism. We
find that the radio properties do not show strong correlations with the star
formation, [O~III] and CO quantities published in the literature. The lack of
evidence of AGN feedback on the global galaxy properties could be due to the
relative time scales of AGN activity and those over which any impact might be
taking place.Comment: 21 pages, 10 figures; accepted for publication in Ap
Prevalence of Presenting Conditions in Grey Seal Pups (Halichoerus grypus) Admitted for Rehabilitation
A retrospective survey was performed on the presenting conditions of 205 live grey seal pups (Halichoerus grypus) admitted to the Cornish Seal Sanctuary in Gweek, United Kingdom between May 2005 and March 2011. The purpose of the survey was to examine the prevalence of various presenting signs at the sanctuary. The presenting signs were classified into nine non-mutually exclusive categories: ocular disorders, nasal disorders, oral disorders, respiratory disorders, orthopaedic disorders, puncture wounds, abrasions, netting injuries, and onychia. The sex ratio of seal pups in this study was 1.35 males per female. Of the 205 examined for rehabilitation, 22 (10.73%) did not survive to release. 68.78% of grey seal pups presented with puncture wounds, 47.80% with respiratory disorders, 46.34% with ocular disorders, 42.63% malnourished, 36.59% with abrasions, 25.37% with oral disorders, 23.90% with nasal disorders, 11.71% with orthopaedic disorders, 9.27% with onychia, and 3.41% presented with netting injuries. 52% were normothermic, 42% were hyperthermic, and 5% were hypothermic. Associations between gender, outcome of rehabilitation, hospitalisation time and presenting disorders were examined. In addition, admissions rates were found to display seasonality. The results of this study will aid in future preparation of grey seal rehabilitation facilities
