Part of Speech Tagging of Marathi Text Using Trigram Method

In this paper we present a Marathi part of speech tagger. It is a morphologically rich language. It is spoken by the native people of Maharashtra. The general approach used for development of tagger is statistical using trigram Method. The main concept of trigram is to explore the most likely POS for a token based on given information of previous two tags by calculating probabilities to determine which is the best sequence of a tag. In this paper we show the development of the tagger. Moreover we have also shown the evaluation done

Comparative assessment of physiological and biochemical changes in the selected plant species growing under hydrocarbon stress

Hydrocarbons have become a serious environmental problem due to industrialization and extensive use of vehicles. Various plant species shows a range of stress responses and adaptations to survive in hydrocarbon stress. This study was conducted to investigate the comparative phytotoxicity of polycyclic aromatic hydrocarbons (PAHs) on plants growing under hydrocarbon stress on the germination and to evaluate the response on seedling growth. For the study, two crop plant species (Brassica juncea L. Czern., and Triticum aestivum L.) and two ornamental plant species (Tagetes erecta L. and Helianthus annuus L.) were taken. Pot experiments were conducted in triplicates of 10 days old seedlings treated with 5, 20, 50 & 100 mg kg-1 concentrations of hydrocarbons. After 20 days, biochemical analysis and antioxidant enzyme activity of these plants were studied. Polyphenol and proline increased with increasing concentration of hydrocarbons which were maximum in H. annuus with 0.909 mg g-1 polyphenol and 0.732 µmol g-1 proline at 100 mg kg-1. Increase in antioxidant enzymatic activities was observed with increasing concentration. H. annuus showed maximum activity at 100 ppm which was ascorbate peroxidase (20.37 Unit g-1 FW), peroxidase (0.212 Unit g-1 FW) and superoxide dismutase (2.13 Unit g-1 FW). HPLC analysis in plants and soil provided the concentration of hydrocarbons present in plants species after 20 days taken up from the treated soil. Plants cultivated in 100 mg kg-1 concentration were analysed and the lowest toxicity observed in H. annuus which was 3.013 mg kg-1 Naphthalene, 7.750 mg kg-1 Phenanthrene and 5.691 mg kg-1 Anthracene while highest toxicity was observed in Tagetes at 8.476 mg kg-1 Naphthalene, 0.398 mg kg-1 Phenanthrene and 0.416 mg kg-1 Anthracene. These results suggested that H. annuus can be adopted in phytoremediation of hydrocarbons soil

A prospective study to assess role of serum lactate dehydrogenase in prediction of adverse outcomes of pre-eclampsia and eclampsia

Background: Pregnancy induced hypertension is one of the most dreaded complication in developing countries. The purpose of this study is to evaluate incidence, risk factors and complications of pre-eclampsia and eclampsia and its relation to serum LDH levels. This was done with a view to making recommendations towards furtherance of objectives of this initiative.Methods: 380 patients with diagnosed eclampsia and preeclampsia were included based on a proforma.Results: Higher grades of proteinuria, higher BP and serum LDH levels >600 IU/L are significantly associated with adverse maternal and fetal outcome.Conclusions: LDH co-relates with adversity of maternal and fetal outcome in eclampsia and pre-eclampsia

Majorization for Certain Classes of Analytic Multivalent Functions

In the present paper we investigate the majorization properties for certain classes of multivalent analytic functions defined by extended multiplier transformation. Moreover, we point out some new or known consequences of our main result

Positive and negative effects of nanoparticles on plants and their applications in agriculture

Nanotechnology is the promising field with its wide applications in biotechnology, pharmaceutical science, drug targeting, nano-medicine and other research areas. This review highlights the positive and negative impact of nanoparticles on plants and its wide applications in agricultural sciences. Effect of NPs in terms of seed germination, growth promotion and enhancement of metabolic rate has been evaluated by several scientific researches. However, NPs also exert their negative effects such as suppression of plant growth, inhibition of chlorophyll synthesis, photosynthetic efficiency etc. Effects of NPs can be either positive or negative it depending upon the plant species and type of nanoparticles used & its concentration. Modern nano-biotechnological tools have a great potential to increase food quality, global food production, plant protection, detection of plant and animal diseases, monitoring of plant growth nano-fertilizers, nano-pesticide, nano-herbicides and nano-fungicides

Role of pelvic and para-aortic lymphadenectomy in epithelial ovarian cancers

Background: Lymphadenectomy in epithelial ovarian cancers has remained a controversial subject. Lack of robust evidence on survival benefits and surgical morbidity associated questions its role in the era of adjuvant chemotherapy. The present study assessed pelvic and para-aortic lymph node removal in epithelial ovarian cancer in Indian women and tried to find clinicopathological correlation of nodal involvement and postoperative implications of lymphadenectomy.Methods: Thirty patients with diagnosis of epithelial ovarian cancer posted for primary debulking surgery were recruited and underwent staging laparotomy along with pelvic and para-aortic lymphadenectomy. Nodal involvement was confirmed on histopathology and various parameters which could predict nodal metastasis were assessed. Patients were followed up for 12 months post-surgery.Results: Nodal yield was ten for pelvic and four for paraaortic nodes. Pelvic node involvement was seen in 26.6% (8/30) of the patients and para-aortic in 15% (3/20) of the patients. Serous histology, higher grade, stage 3 and above, positive peritoneal cytology, omental involvement showed a higher lymph node involvement though not statistically significant. Para-aortic lymphadenectomy was associated with increased operating time, blood loss and longer hospital stay.Conclusions: Lymphadenectomy increases morbidity and decision should be based on predictors of nodal involvement

Unsuspected rupture in unscarred uterus at an early gestation: a clinical dilemma

Spontaneous uterine rupture in early second trimester is extremely rare specially in absence of predisposing factors. A pregnant patient presented at 15 weeks’ gestation with lower abdominal pain and vomiting since two days. Ultrasound findings and deranged liver function tests reinforced the diagnosis of chronic liver disease with pregnancy. Clinical course a day later raised suspicion of ruptured uterus and patient was immediately taken for laparotomy. Intra-operatively, hemoperitoneum and 4 cm fundus rent was found. Total hysterectomy was performed and histopathology revealed placenta percreta as the probable cause of spontaneous rupture. The case highlights that a high index of clinical suspicion, an attentive daily clinical examination and immediate surgical management can avert life-threatening catastrophe

Isolation of Halophilic Bacteria and Their Screening for Extracellular Enzyme Production

617-622Halophiles are those microorganisms which are found at high salt concentration. These microorganisms have the capability to form a wide array of bioactive substances that have different applications in various industries. This work focussed at the isolation and screening of various halophilic bacterial strains from different places in Rajasthan and Tamil Nadu. Using a complete medium with different salt concentrations, 70 halophilic bacteria were isolated from 4 different sites. These isolated bacteria were then examined and screened out for the synthesis of different extracellular enzymes, such as cellulase, lipase and amylase. Out of the total, 24 isolates were found positive for amylase, 9 for lipase and 16 for cellulase. These enzymes can perform the hydrolytic activity at high salt concentrations. The various halophilic bacterial strains isolated from various places show a prospective for use in a range of biotechnological and molecular biology experiments and the extremozymes obtained from these bacteria have great industrial importance
