Authors: SINGH S. V. , KRIPALANI R. H. , SAHA P. , PRASAD K. D. 
Published: February 2022

Climatic characteristics of occurrence of dry spells over 7 meteorological subdivisions lying in semi-arid parts of India are studied by using 23 years of spatially averaged sub-divisional rainfall data. Five different thresholds have been used to decide the occurrence of dry or wet day over the sub-divisions. Similar characteristics in occurrence of dry spells have been studied for 6 stations lying in the same area. The Markov chains of order 1 and 2 have been fitted to the frequency of occurrence of dry spells over the stations and on testing the chain of order 2 are found to fit better.

Composite charts of probability of occurrence of rain around depressions located in various geographical areas have been prepared by using daily rainfall data of 220 stations for 19 years. With the help of these charts the role of depressions in alleviating drought situation is examined.

Finally multiple linear regression equations are developed by stepwise screening method to predict the daily rainfall amounts over these subdivisions by using large scale synoptic parameters. When tested on an independent sample of equal size these equations showed skill scores varying from .22 to .54 in forecasting the terciles of rainfall.
On some climatological aspects of drought in India

Published: February 2022

Based on data from 1875 to 1980, an attempt has been made in this paper to compile and collect drought climatology of India. Only "meteorological drought", i.e., rainfall deficiency exceeding 25 % of the normal has been considered. Frequency of occurrence of drought in different meteorological sub-divisions has been obtained which has been used to determine its recurrence period. Drought has been classified into moderate and severe categories and the probability of occurrence of these types in different sub-divisions computed and discussed. Depending upon the area of the country affected, drought has been further classified into different categories, viz., localised, semi-vast, vast extensive and calamitous, observed frequency of each type determined. Decadal representation of the drought incidence has been obtained and used to predict its occurrence in any 10.year period. The series is also subjected to power spectrum analysis and significant peaks obtained and discussed.

Since no rational criteria to define an year as a good or bad monsoon year for the country as a whole exists at present, an objective and pragmatic approach to solve this problem has been attempted. The following two categories were separately adopted to consider a year as a drought year, viz.,

(i) When the percentage area affected exceeds 20%,
(ii) When the area exceeds 25%.

Sequences of a drought year or a good monsoon year have been obtained. This has subsequently been examined to obtain probabilities of a drought year following (a) 3 consecutive good years, (b) 4 good years, and (c) 5 good years. Similarly chances of two consecutive years of drought after each of 3, 4 and 5 consecutive got the monsoon years have been determined. These sequencies have also been utilised to find persistence in occurrence of good or bad (drought) monsoon years and subjected to X2-test to determine its statistical significance.

Published: February 2022

Aims:
The relationship between prosthetic position and range of motion (ROM) after total hip arthroplasty (THA) has been rigorously examined. However, the effects of limb lengthening on postoperative hip ROM remain unclarified. We aimed to examine the effect of limb lengthening on hip ROM after THA.

Methods:
We retrospectively reviewed the data from 120 patients who underwent unilateral THA. Univariate and multivariate regression models were used to evaluate the effects of the following patient- and surgery-related covariates on hip flexion ROM at 3, 6, and 12 months after THA: age, sex, body mass index, diagnosis, preoperative University of California Los Angeles activity score, preoperative Oxford Hip Score, preoperative flexion ROM, amount of leg lengthening, cup inclination, and cup anteversion.

Results:
A large preoperative hip flexion ROM was the strongest predictor of a large hip flexion ROM at 12 months after THA (standardized coefficient: 0.519, P < 0.0001). A larger amount of leg lengthening was associated with a smaller postoperative hip flexion ROM (standardized coefficient: −0.159, P = 0.039), and male sex was another predictor of a smaller postoperative hip flexion ROM (standardized coefficient: −0.204, P = 0.014). Cup inclination (P = 0.99) and anteversion (P = 0.18) were not significantly associated with hip flexion ROM at 12 months after THA.

Discussion:
A large amount of limb lengthening was associated with decreased hip flexion ROM after THA. In THA, minimizing the leg length discrepancy is important; however, the postoperative improvement in hip flexion ROM may be limited when a large amount of leg lengthening is needed.

Authors: Iqbal Themi  , Perdana Aditya 
Published: February 2022

Abstrak: Evolusi perkembang internet dan munculnya media baru (Media Sosial) mempengaruhi banyak peristiwa politik, yang paling sering disoroti adalah terkait pengaruh penggunaan media sosial terhadap partisipasi politik. Namun sejauh ini literatur yang ada hanya menunjukan pengaruh langsung antara penggunaan media sosial dan partisipasi politik tanpa proses mekanisme psikologis yang terjadi. Selain itu, fenomena tagar di Indonesia juga kurang mendapat perhatian para ilmuwan padahal tagar sebagai bagian dari konsep viralitas memiliki kemampuan penyebaran informasi dalam skala besar dan cepat bahkan dalam beberapa kasus mempengaruhi gerakan sosial. Oleh karena itu, artikel ini berupaya untuk menguji pengaruh konten tagar #2019GantiPresiden terhadap partisipasi politik online dan offline (low/high) dengan menggunakan Model Partisipasi Politik Media Sosial (SMPPM). Adapun metode yang digunakan adalah kuantitatif dengan teknik pengumpulan data berdasarkan kuisioner dan teknik analisa regresi linier sederhana. Hasilnya (1) pengaruh tagar #2019GantiPresiden terhadap partisipasi online (low/high) lebih besar dibanding terhadap partisipasi offline (low/high), (2) konten tagar #2019GantiPresiden tidak memiliki tujuan partisipatif dan dan tidak lebih dominan dibanding tujuan individu sekalipun mereka sepakat dengan tagar tersebut, sehingga (3) tidak dapat meningkatkan rata-rata responden yang pernah melakukan partisipasi online/offline (low) menuju partisipasi online/offline (high).

Context.—
The diagnosis and clinical management of patients with diffuse gliomas (DGs) have evolved rapidly over the past decade with the emergence of molecular biomarkers that are used to classify, stratify risk, and predict treatment response for optimal clinical care.

Objective.—
To develop evidence-based recommendations for informing molecular biomarker testing for pediatric and adult patients with DGs and provide guidance for appropriate laboratory test and biomarker selection for optimal diagnosis, risk stratification, and prediction.

Design.—
The College of American Pathologists convened an expert panel to perform a systematic review of the literature and develop recommendations. A systematic review of literature was conducted to address the overarching question, “What ancillary tests are needed to classify DGs and sufficiently inform the clinical management of patients?” Recommendations were derived from quality of evidence, open comment feedback, and expert panel consensus.

Results.—
Thirteen recommendations and 3 good practice statements were established to guide pathologists and treating physicians on the most appropriate methods and molecular biomarkers to include in laboratory testing to inform clinical management of patients with DGs.

Conclusions.—
Evidence-based incorporation of laboratory results from molecular biomarker testing into integrated diagnoses of DGs provides reproducible and clinically meaningful information for patient management.
U.S. Navy Ship-Model Powering Correlation and Propeller RPM Prediction
Authors: Karafiath Gabor 
Published: February 2022

The US. Navy is in the process of reexamining the ship model powering correlation policy to reflect the ship-model correlation allowance experience obtained on 17 ships since 1980. A correct estimate of the correlation allowance is crucial to the accurate model test based prediction of ship power and propeller RPM Relative to the old correlation data, the new post-1980 correlation data tends to confirm the correlation allowance for mid-size ships. Relative to the Naval Sea Systems Command (NAVSEA) correlation curve, the correlation allowances for long ships over 600 ft and for short 200. ft ships tends to be lower.
Both the predicted power and the predicted RPM is compared to ship trial data for all the new data. The model test data was reanalyzed with the correct correlation allowance determined from ship powering trials in order to determine the accuracy of the propeller RPM prediction methodology. Propeller pitch was known for certain on fixed pitch propellers and on controllable pitch propellers operated at pitch values limited by mechanical stops. For these cases. the propeller RPM calculated with the post-trial correlation allowance was within +0.9% and -2.4% of the trials measurement. These data tend to validate the model test extrapolation procedures in use at the Naval Surface Warfare Center, Carderock Division (NSWCCD) for the typical combatant I auxiliary Naval ship.
On ships with controllable pitch propellers operating at the nominal design pitch there was much greater scatter in the predicted RPM, indicating that the pitch of the operating propeller was not really known accurately. The propellers may have been operating at slightly off design pitch conditions. The development of in-hub pitch sensors is highly recommended.
The correlation allowance for ships launched after 1982 is on the average 0.0002 lower than the correlation allowance for ships launched prior to l 982. Ships with ablative type paint tended to show lower correlation allowance than ships without ablative paint. Explanations for the decreased correlation allowance for the post-1982 launched ships are examined in the paper.

Background: Cola millenii K. Schum. is a member of Cola which is lesser-known in the family Malvaceae. The leaf is used in the treatment of ringworm, scabies, gonorrhoea, diarrhoea, cough and ophthalmia by the locals.
Aim: The study determines various taxonomic, pharmacognostic and phytochemical standards helpful to ensure the identity, purity, safety and efficacy of the medicinal plant, C. millenii.
Methodology: The pharmacognostic characterization was determined following the guidelines given by the World Health Organization (WHO). Parameters determined included macroscopy, microscopy, powder microscopy, petiole anatomy, chemomicroscopy, micromeritic properties, ash values, extractive values, fluorescence analysis and preliminary phytochemical screening.
Results: Preliminary phytochemical screening for both the leaf and stem ethanol extracts showed the presence of phytochemicals. Epidermal cell shapes were polygonal with straight anticlinal walls. Stomatal distribution was hypostomatic with hexacytic, anisocytic and anomocytic stomata on the abaxial surface. Unicellular and glandular trichomes were observed on the abaxial surface. Areolation was quadrangular with calcium oxalate crystals observed along the veins. The chemomicroscopic study revealed the presence of lignin, starch, cellulose, oils, calcium oxalate crystals, mucilage and protein for both leaf and stem respectively. The fluorescence characteristics showed the presence of different colours supporting the presence of various phytoconstituents for both leaf and stem. The flow properties for both leaf and stem were fair and passable with the angle of repose of 40.6o and 36.8o respectively. The quantitative epidermal studies, chemomicroscopic and fluorescence characteristics revealed characteristic features for the drug. The physico-chemical results for leaf and stem gave total ash of 5.5 % and 12.07 %, water-soluble ash of 1.19 % and 3.39 %, acid-insoluble ash of 0.90 % and 2.29 % and moisture content of 4.49 % and 16.33 %, water-soluble extractive of 26.30 % and 22.50 %, ethanol-soluble extractive of 24.30 % and 16.80 %, methanol-soluble extractive of 20.90 % and 2.50 % and ethyl-acetate acetate-soluble extractive of 6.60 % and 1.10 % respectively. The GC-MS analysis revealed the presence of 31 and 45 phytochemical constituents for the leaf and stem respectively.
Conclusion: The data generated from the present study would help to authenticate C. millenii and also affirm its folklore use in traditional medicine.
