Stronger reconstruction of distance-hereditary graphs

A graph is said to be set-reconstructible if it is uniquely determined up to isomorphism from the set S of its non-isomorphic one-vertex deleted unlabeled subgraphs. Harary’s conjecture asserts that every finite simple undirected graph on four or more vertices is set-reconstructible. A graph G is said to be distance-hereditary if for all connected induced subgraph F of G, dF (u, v) = dG(u, v) for every pair of vertices u, v ∈ V (F). In this paper, we have proved that the class of all 2-connected distance-hereditary graphs G with diam(G) = 2 or diam(G) = diam(Ḡ) = 3 are set-reconstructible.The second author is supported by the University Grants Commission, Government of India.

Effect of Calcium Nitrate and Potassium Nitrate Priming on Seed Germination and Seedling Vigour of Papaya (Carica papaya L.)

The effect of seed priming with calcium nitrate Ca (NO3)2 and potassium nitrate (KNO3) on germination and seedling vigour were studied in papaya varieties. Open pollinated local (gauty) papaya seeds were soaked in Ca (NO3)2 and KNO3 solutions (10000 ppm, 15000 ppm and 20000 ppm) up to 24 hours and germination percentage and seedling characteristics were recorded. The least number of days taken for seed germination (4.33 days), the highest germination percentage (82.56 % ), the highest shoot length (14.31 cm) the highest fresh biomass (1.36 g) and dry biomass (0.174 g) were recorded in 10000 ppm   Ca(NO3)2 treatment. Further, seeds of papaya varieties viz., Arka Surya, Arka Prabhat and Madhu bindhu were treated with 5000 ppm, 10000 ppm and 15000 ppm Ca (NO3)2 and observed that Arka Prabhat seeds treated with 10000 ppm Ca (NO3)2 hadtaken the least number of days for germination (4.75 days) and also the highest shoot length (25.2 cm). The results of the experiment proved the significant effect of calcium ions over potassium ions on papaya seed germination and seedling vigour

ANTIPYRETIC ACTIVITY OF ETHANOL AND AQUEOUS EXTRACT OF ROOT OF ASPARAGUS RACEMOSUS IN YEAST INDUCED PYREXIA

ABSTRACT Objective: To evaluate and compare the in vivo antipyretic activity of the aqueous and the ethanol extract of root of Asparagus racemosus. Methods: The presence of phytochemicals like flavonoids and saponins were identified by TLC and the invivo antipyretic activity was determined by brewer's yeast induced pyrexia method. Results: The results showed that the ethanol extract of root of Asparagus racemosus possessed significant antipyretic effect compared to the aqueous extract which may be attributed to the presence of flavonoids and saponins in the extracts whose presence were observed in TLC. Conclusion: This study provides evidences for the antipyretic activity of Asparagus racemosus which could partly contribute to its ethno medical use.   Key Words: Asparagus racemosus, Antipyretic effect, flavonoids ,saponins, TL

A comparative study between intramuscular oxytocin and intramuscular methyl ergometrine in the active management of third stage of labour

Background: To compare the efficacy of prophylactic IM oxytocin 10U and IM methyl ergometrine 0.2mg on duration of third stage of labour, amount of blood loss during the third stage of labour and associated side effects.Methods: 50 low risk antenatal women with singleton pregnancy at term gestation in vertex presentation admitted for vaginal delivery, were randomly allocated into 2groups of 25 each and managed actively in the third stage of labour either with 10 U oxytocin IM or with 0.2mg methyl ergometrine IM immediately after the birth of the baby. The main outcome measures were the difference between the 2groups with regard to: duration of third stage of labour, blood loss by volume, difference in haemoglobin and haematocrit, need for blood transfusion, additional uterotonics and side effects of drugs.Results: The mean duration of third stage of labour in the oxytocin group was 6.68±2.17min and in methergine group was 6.4±1.93 min. Mean blood loss was 302±75.6ml and 282.8±58.27ml. Mean fall in Hb was 0.92gm% and 0.812gm%. Mean fall in PCV was 2.36% and 1.88%. 2women in oxytocin group and 1woman in methergine group received additional 0.2mg methergine. 3women in both groups received 1unit of blood transfusion. 8women who received methergine had side effects while only one in the oxytocin group, with a p value 0.004 which is statistically significant.Conclusions: This study has shown that both oxytocin and methylergometrine were equally efficacious. However, oxytocin had significantly better safety profile and lesser contraindications for usage

Studies on Fruit Development in Pink and White types of Wax Apple (Syzygium samarangense Merr. & Perry) in Goa, India

Fruit development studies were taken up in white and pink types of wax apple trees aging twelve years old at Goa, India. The study was initiated with the onset of flowering in November during the year 2018. After tagging the flowers on anthesis, samples were drawn periodically to record parameters like fruit weight, fruit volume, fruit length and diameter (upper, middle and lower), quality or biochemical parameters like total acids and sugars. Relative growth rate (RGR) was calculated for all parameters and graphs were generated. In both the types, fruit weight, fruit volume, fruit length and diameter increased in a sigmoidal pattern. The quality characters like TSS, total acids and total sugars also showed a sigmoidal pattern of increase whereas the increase in reducing sugars exhibited a double sigmoidal pattern of increase. It was evident from the curves that there was pronounced peak in growth rate between 21 and 28 days after anthesis for fruit weight, fruit volume, fruit length and diameter, in both pink and white types of wax apple

Variability and Genetic Divergence in Vegetable Cowpea Germplasm of Goa

Vegetable cowpea or Yard long bean [Vigna unguiculata var. sesquipedalis L. (Walp)] is a warm season leguminous crops grown especially for vegetable purpose along the west coast of India. In Goa, pole type varieties are preferred over bushy types as they offer multiple harvests with comparatively longer pods. There is wide variability found for different morphological and other traits in the local types cultivated in the state of Goa. Exploration of genetic variability in the available germplasm is a prerequisite for initiation of any successful breeding programme. Twenty nine genotypes of vegetable cowpea including three improved varieties collected from different parts of Goa state were evaluated for twelve quantitative characters including yield. High variability was observed for pod yield/plant, number of pods/plant and pod length. The high variability for pod yield per plant is apparent as the pod yield ranged from 315.25 to 2070.45 g/plant with an average of 827.48 g per plant. Pod yield depends on number of pods per plant, pod length and pod weight. Number of pods per plant ranged from 36.65 to 147.80. Pod weight depends on pod length, number of seeds per pod and hundred seeds weight. Wide variation was observed for all these characters in the present study. The GCV value was maximum for pod yield per plant (g) followed by pod weight (g) and number of pods per plant. Low values of GCV were observed for days to first flowering, days to first harvest and number of seeds per pod. In the present study, the twenty nine genotypes could be grouped into fourteen clusters based on genetic distance. High coefficient of variation was observed for pod yield per plant, pod weight, number of pods per plant and pod length indicating their significant contribution in determining the inter cluster distances

A MANUAL INSERTION FACET FOR UNCERTANITY FROM THEIR FETCH RESULTS

The aggregating frequent lists inside the top internet search engine results in mine query facets and implement a method known as QDMiner. More particularly, QDMiner extracts lists totally free text, HTML tags, and repeat regions within the top internet search engine results, groups them into clusters when using the products they contain, then ranks the clusters and products for a way the lists and products can be found in the very best results. Our suggested approach is generic and doesn't depend on any type of domain understanding. The primary reason behind mining facets differs from query recommendation. We advise an organized solution, which we call QDMiner, to right away mine query facets by removing and grouping frequent lists totally free text, HTML tags, and repeat regions within top internetsearch engine results. We further look at the issue of list duplication, and uncover better query facets may be discovered by modeling fine-grained similarities between lists and penalizing the duplicated lists. Experimental results show many lists are available and helpful query facets may be discovered by QDMiner. Our recommended approach is generic and doesn't depend on any kind of domain understanding. In order that it can cope with open-domain queries. Query dependent. rather in the fixed schema for the concerns, we extract facets inside the top retrieved documents for every query

Impact of mothers’ knowledge and support for sustaining exclusive breastfeeding

Background: Breast milk is the best milk for the baby. It is beneficial for the baby as well as the mother, family, and nation. In spite of an established fact, still, a very low percentage (44.2%) is implementing it. Objective: The objective of this study was to find out the knowledge, concerns, and difficulties in breastfeeding and the obstacles in the practicing breastfeeding. Materials and Methods: A cross-sectional study was done at pediatric clinics in Warangal. A total of 1010 lactating mothers who were presenting for regular check-ups were enrolled. After taking oral consent, mothers were interviewed through a predesigned questionnaire containing 50 questions on pre- and post-natal counseling received, and knowledge of exclusive breastfeeding, importance of skin-to-skin contact (SSC), and their educational status and hygiene. The entire session of interview was carried out in the optimum privacy to create a favorable environment of acquiring the data. Results: Of 1010 mothers enrolled, only 25.4% had received antenatal counseling, 15.8% had received postnatal counseling regarding exclusive breastfeeding, 56.4% followed exclusive breastfeeding (EBF), and SSC was maintained by only 2%, after delivery which played an important role in breastfeeding, p=0.000003 for antenatal counseling and EBF. Conclusion: More attention should be given in educating mothers when they conceive, regarding breastfeeding, its problems and skills, during their first visit to health-care professionals

Fertility problems in women with polycystic ovary syndrome

Background: PCOS (Poly Cystic Ovary Syndrome) is the most common endocrine disorder in women of reproductive age with high prevalence. It is a leading cause of infertility in women; this draws an attention to this issue. In this study we aimed to know the prevalence, clinical features, fertility problems and management of PCOS.  Methods: In this prospective observational study, women who consulted Obstetrics & Gynaecology department were screened to identify the PCOS problems through clinical histories, PCOS questionnaire and ultrasonography over a period of 6 months at Rajiv Gandhi institute of medical sciences (RIMS) in Kadapa, India. Patients diagnosed with PCOS were assessed for their clinical manifestations, severity, life style and treatment given, and were educated accordingly through patient counselling and leaflets.Results: We observed 6.39 % prevalence out of 970 women. 59 (95.1%) patients were complained irregular menstrual cycles. Infertility was significantly high in PCOS women i.e. 13.35%. 64.4% of PCOS patients had miscarriages.Conclusions: PCOS is a complex condition with high prevalence of fertility problems, needing due attention. There is need to create attentiveness towards this issue. Early diagnosis and proper management with appropriate medicines and lifestyle modifications will improve the condition and prevents complications.
