A note on the homotopy invariance of Pontrjagin classes

AbstractWe prove that the classical result of Wu that, for every n ⩾ 1, the integral Pontrjagin class pn modulo 3 is homotopy invariant is the only and best possible result, ‘only’ in the sense that no other Pontrjagin classes of stable vector bundles—rational, integral, multiple of integral or integral mod p, p ≠ 3, are homotopy invariant and ‘best’ in the sense that pn mod 3r is not homotopy invariant if r > 1

Condom catheter: a simple and efficacious alternative of hysterectomy in postpartum haemorrhage

Background: The aim of this study was to evaluate the effectiveness of the condom catheter in treating postpartum hemorrhage refractory to medical treatment.Methods: This prospective study included 21 women with postpartum hemorrhage treated with a condom catheter as a conservative therapeutic option.Results: The condom catheter was successful in controlling hemorrhage in 90.4% of the women. It was effective in all women with vaginal delivery (11 of 12) and highly effective in women with uterine atony who did not respond to medical uterotonic treatment (6 of 7 women).Conclusions: Its ease of use and high effectiveness make the condom catheter a useful approach for the conservative management of acute postpartum hemorrhage. This device reduces bleeding, shortens the hospital stay and avoids the need for surgical management

Study of drug utilization in intensive care management of neonates at tertiary care hospital

Background: Newborn infants form a highly vulnerable group. Compared to adults they are more prone to adverse drug events. Exposure to multiple drugs is also known to be a leading factor in their well-being. Many advances have been made in this area, yet there is a paucity of information to guide rational prescribing in newborns. This study was conducted to evaluate the drug prescribing trends in a Neonatal Intensive Care Unit (NICU) of a tertiary care hospital in Bidar.Methods: A prospective study was undertaken, over a period of 3 months at the government teaching hospital, Bidar. Neonates of either sex admitted to NICU were included. Data collection was done by scrutinizing the inpatient case sheets and investigation reports.Results: A total of 100 neonates were admitted and 11 deaths were noted. Most common cause for admission was septicaemia. The total number of drugs prescribed was 488. The average number of drugs per prescription was 4.9. Antimicrobials were the commonest agents prescribed and intravenous route was the commonest route of drug administration. Most of the drugs were prescribed by generic names.Conclusions: In our study it was observed that polypharmacy is commonly observed practice in NICU patients. Most of the antibiotics were prescribed empirically. The dose and frequency of administration was mostly as per the standard guidelines

Topological invariance of integral Pontrjagin classes mod p

AbstractIt is proved that integral Pontrjagin classes Pk mod p are topological invariant if p is odd, k < n(p) and they are not topological invariant if k ⩾ n(p), where n(p) is the smallest value of k for which p divides ek and ek is the smallest positive integer such that ekpk is topological invariant. For example, pk mod p is topological invariant for p = 3, 5, 11 etc. for every k ⩾ 1 but not topological invariant for p = 7 and k ⩾ 2

Detection of QRS Complex in ECG Signal using Wavelet Transform and Thresholding Technique

The Electrocardiogram is a powerful tool that provides the remarkable information about the cardiac disorders. QRS complex detection in ECG signal is very important for finding some cardiac disease. QRS complex has been detected by wavelet transform. Symlet-4 wavelet has been used for QRS detection. In the wavelet transform, thresholding also an important parameter for obtaining the higher output. The Rigersure type threshold gives highest sensitivity of 99.34%.The analysis has been done on ECG data files of the MIT-BIH Arrhythmia Database.

Seasonal Variation of Trace Metals in Ancient Pond and Its Impact on Morphometry of Claris Batrachus: A Case Study of Varanasi City

Varanasi, often termed India's spiritual nucleus, boasts a rich tapestry of historical and ecological elements, most notably its ancient "kunds" or water tanks. These kunds, deeply intertwined with religious ceremonies and local legends, are ecological keystones supporting diverse aquatic life. This study concentrates on five significant kunds: Surya Kund, Ishwarangi Kund, Pishach Mochan Kund, Kurukshetra Kund, and Pushkar Kund. The objective was to assess the seasonal variations of trace metal concentrations in these water bodies and understand their impact on the morphometry of indigenous species, with a spotlight on Clarias batrachus. Preliminary findings indicate fluctuating metal levels, particularly during monsoon months, with corresponding morphological alterations in the observed fish species. Such results accentuate the importance of preserving these ecologically critical and culturally treasured sites against the challenges of urbanization and modern practices in Varanasi.&nbsp

A study comparing non-gestational diabetes mellitus and gestational diabetes mellitus in antenatal patients in a tertiary care center

Background: Gestational diabetes mellitus is defined as any glucose intolerance with the onset or first recognition during pregnancy. Objectives of this study were to diagnose cases of GDM by screening with DIPSI criteria at less than 28 weeks. And observation and comparison of maternal and perinatal outcome in women diagnosed of GDM in less than 20 weeks and at 24-28 weeks.Methods: This was the prospective analytical study conducted in the department of obstetrics and gynecology for one year in Muzaffarnagar medical college and Hospital. After history taking, clinical and obstetrics examination 1503 antenatal patients of less than 28 weeks were enrolled underwent screening with DIPSI criteria. Out of which 80 patients with abnormal OGTT of gestational age less than 20 weeks and 69 patients with abnormal OGTT of gestational age 24 -28 weeks.Results: In early diagnosed GDM group alive and healthy babies were slightly lower as compared with late diagnosed GDM group.Conclusions: The diagnosis of GDM gives us an opportunity in identifying individuals who will be benefitted by early therapeutic intervention with diet, exercise, and normalizing the weight to delay or prevent the onset of the disease

Slavlje božanskoga plesa: Kult Yoginī/ Ḍākinī u drevnom hinduizmu i budizmu

Music and dance have long been a component of the celebrations of the people of all nations and on all continents. Music and dance are also used as a method to transcend the profane and to experience ecstasy and bliss. The objective of this research is to analyse the “Divine Dancing Celebration” as practised in India and Tibet by including heroic and ecstatic dances that are believed to grant immortality; also included are the sculptural dynamics of rapturous dance which symbolizes transformation and happiness. The paper also looks at the iconography of some Yoginī/ Ḍākinī who represented the dancing cult and the symbolic meaning buried inside the icon in an effort to make a connection between dance and the cult of Yoginī/ Ḍākinī. Yoginī / Ḍākinī exhibit their bodies and faces, radiating youth and beauty while advocating for freedom from all social restrictions. The Yoginī is dressed in charnel ground jewellery and performs a dance in a field of decaying corpses. Her body is vividly colored and gives the impression of being formed of light; its transparency reveals a sparkling yet hollow nature. The interior of her body is a vast, limitless domain, which may also contain visions. The female force, which can occasionally be evil and may result in destruction and beheadings, is shown as a component of each element existing in the cosmos in the iconographies of the Yoginī. The significance of this research is that it demonstrates the importance of the Yoginī/ Ḍākinī cult in ancient and early medieval India and Tibet. Although this cult is still practised in some manner in South East Asia but not in India, it has lost its relevance and no longer is known to anyone in India. This study is an initial step in educating the general population on this prominent cult of Hinduism and Buddhism and its significance.Ples i glazba oduvijek su bili sastavni dio ljudskih slavlja u svim narodima i na svim kontinentima, kao i način nadilaženja profanoga i iskustva božanske ekstaze i ushićenja. Cilj je ovoga istraživanja raščlaniti “Slavlje božanskoga plesa” kako se prakticira u Indiji i Tibetu na način da se u analizu uključuju herojski i ekstatični plesovi koji mogu donijeti besmrtnost, kao i skulpturalna dinamika zanosnoga plesa, što simbolizira preobrazbu i sreću. U ovom radu autori također razmatraju ikonografiju nekolicine joginija i dakinija koje su predstavljale kult plesa, a i simbolično značenje skriveno u ikoni s ciljem da se uspostavi veza između plesa i kulta jogini/dakini. Joginiji i dakiniji pokazuju se svojim tijelima i licima te zrače mladošću i ljepotom, a istovremeno zagovaraju slobodu od svih društvenih ograničenja. Jogini je odjevena u nakit od ljudskih kostiju te izvodi ples u polju raspadajućih leševa. Tijelo joj je živo obojeno te ostavlja dojam da je od svjetla oblikovano. Prozirnost tijela otkriva blistavu ali šuplju narav. Unutrašnjost tijela je nepregledni prostor bez granica koji može i u sebi nositi viđenja. Ženska sila, koja može katkada biti zla i može završiti razaranjem i odrubljivanjem glava, prikazana je kao sastavni dio svakoga kozmičkoga elementa koji je prisutan u jogini ikonografijama. Znakovitost ovoga istraživanja može se prepoznati u tom što pokazuje važnost jogini/dakini kulta u drevnoj i ranoj srednjovjekovnoj Indiji i Tibetu. Iako se kult još uvijek prakticira na neki način u jugoistočnoj Aziji, ali ne i u Indiji, izgubio je na važnosti i nije više nikomu u Indiji poznat. Ova studija predstavlja početni korak prema poučavanju opće populacije o pitanju ovoga istaknutoga kulta hinduizma i budizma te ističe njegovu važnost

A prospective randomized controlled trial showing efficacy of luteal phase low molecular weight heparin in fresh non-donor IVF/ICSI cycles in women with previous implantation failures

Background: Implantation failure is a major challenge in in-vitro fertilization (IVF) cycles. The present study was undertaken to determine the immunomodulatory effects of heparin in patients with previous implantation failures undergoing assisted reproductive techniques (ART).Methods: This was a prospective randomized controlled trial with sample size of 100 patients who had history of at least one previously failed IVF/ICSI. Study group of 50 patients received heparin and 50 patients in control group received routine luteal phase support.Results: Primary outcome of the study was implantation rate (IR) which was 11.03% in the study group was and 5.48% in the control group (p=0.08). Biochemical pregnancy rate and clinical pregnancy rate in the study group was 18% and 12% in the control group (p=0.401). Calculated live birth was 5.15% and 3.42% in the study and control groups respectively (p=0.562). 11 babies were taken home from the study group and 6 from the control group (p=0.18).Conclusions: The result of this pilot study showed relative increase in implantation rates (IR) suggesting beneficial effects of heparin in patients with repeated implantation failures. Although these changes are not statistically significant, the presence of an increasing trend in all the outcome parameters signify the possible benefits of heparin proving for the present study hypothesis

Assessment of Respiratory Disorders Using Speech Parameters

In today�s scenario detection of diseases using voice analysis has become one of the important research topic. In order to determine if the person is suffering from some kind of illness, the information extracted by voice analysis about the person�s health can be helpful, as a number of pathological disorders are related with nasal, neural, respiratory and larynx diseases etc. In this paper, the analysis of voice parameters is done in order to differentiate between normal and affected person. The speech samples are recorded and Pitch , formant frequencies, intensity was extracted from the speech signals. The mean values variation of these parameters is used in identifying the difference between normal and affected person
