Abstract :

The livelihood of fishermen is such that he crosses the country border unknowingly and poses threats to them by being killed or captured. The sea borders between countries are not easily identifiable which is the main reason behind this problem. “Border alert system for fisherman using GPS” describes about a system which helps the fishermen by notifying the country border. Global Positioning System (GPS) and Global system for mobile communication (GSM) are used for this purpose. Here GPS receiver is used to find the current location of the fishing boat. Using GPS, present latitude and longitude values are sent to microcontroller unit. Later the controller unit identifies the current location by comparing the present latitude and longitudinal values with the predefined value. After the comparison, border alert system aware the fishermen that they are about to reach the nautical border. The region is divided into normal zone and warning zone. When the boat is in normal area, the LCD displays normal zone. Thus they can make it clear that the boat is in normal area. In case if it moves further and reaches the warning zone, the LCD displays warning zone.

Abstract :

The main purpose of this study is to determine the effect of language of encouragement on mathematics anxiety, self-efficacy, and mathematics performance of college students. The study utilized the Pre-test Post-test Comparison Group Design. The effect of language of encouragement and praise on mathematics anxiety, self-efficacy, and mathematics performance was determined by comparing the students’ pre-test and post-test scores. The results revealed that techniques have adaptive effects on mathematics anxiety, self-efficacy, and mathematics performance of students. To support the claim that encouragement is better than praise, the mean differences of the post-tests of two groups were obtained using t-test for independent samples. The results showed significant results in all outcome variables which reveals that encouragement can reduce mathematics anxiety, increase self-efficacy, and improve mathematics performance of students much better than praise. Mathematics anxiety and self-efficacy has a significant moderately low negative correlation, mathematics anxiety and mathematics performance has no significant correlation, and self-efficacy and mathematics performance has a significant moderately low positive correlation. Thus, mathematics performance of students can be better determined based on the level of their self-efficacy than on their level of mathematics anxiety.

Abstract :

In Mersin (Tarsus-Anamur Coastline), four seasons’ vegetation samples are gathered from around 20 estuaries and diatom percentages are determined. Mostly Navicula, Pinnularia, Gomphonema, Synedra, Nitzchia and also Triceratum, Cyclotella, Cymbella, Coconeis, Diatoma, Amphora, Gyrosigma, Licmophora species have been observed. The other determined organisms are bacteria and algae parts, as Vaucheria, Pediastrum, Pandorina, Peridinium, Phacus and Euglena which are seen in almost all rivers, and Ankistrodesmus, Kirchneriella species, which are found in Kuyuluk Creek.Over the past two years, the Metropolitan Municipality paved the river-beds with concrete to prevent flooding, and depending on the increased population and settlement, water pollution has started to emerge. That is why the periodic inspections are of the utmost importance. For 2013-2014, the data of Paşasuyu, Göksu and Tarsus rivers demonstrate a clearer picture. We believe that this research will increase the interest in the river ecosystems of Mersin, contributing to future researches in this field.

Abstract :

Ingestion of Gastrointestinal (GI) foreign bodies represent a challenging scenario since the patient usually do not remember unintentional ingestion of foreign body. Accidentally ingested foreign body for the most part pass through the GI tract [1,2].Fish bones are one of the most commonly ingested foreign objects. If complications occur due to the impaction/perforation owing to their sharp pointed edges and secondary complications thereof – they are rarely diagnosed preoperatively as the clinical symptoms are non-specific and may mimic more commoner acute abdominal conditions like appendicitis or diverticulitis . Increased morbidity as a result of delayed diagnosis is a challenge to be overcome[5] and early diagnosis with  appropriate clinical history and  radiological investigations has to be made for timely treatment.

We describe a rare case of a 45 year old male patient with foreign body (FB) i.e fish bone ingestion presenting with nonspecific abdominal pain for a week duration. Abdominal ultrasound and Computed tomography(CT) scan showed an ill-defined intraperitoneal mass in the mid abdomen with a foreign body measuring 46mm in length suspicious for fish bone. On laparotomy an intraabdominal abscess containing a fish bone was resected.

Abstract :

In the past, the negative about the possibility of extraterrestrial intelligences coming into contact with the humankind was due to several factors, but at present, there is evidence from several fields challenging this mainstream. We hypothesized that authentic Close Encounters of Fifth Kind (CE5thK) could probably be happening. We designed and applied an original approach with qualitative and quantitative variables constituting a rule of 12 criterions for defining a high probability, low probability or inconclusive evidence in order to set the authenticity of 72 cases of alleged CE5thK. A high probability was considered as authentic. We found 47 cases to be low probability, none case to be inconclusive evidence and 25 cases to be high probability to be an authentic phenomenon. Using an original approach, we found evidence to support that advanced contact from ETI with human beings probably is happening on the Earth at present. Additionally in these authentic CE5thK cases, there are important and revolutionary information with amazing potential for our society in several fields of knowledge.

Abstract :

The uterine artery Doppler velocimetry (UADV) are described by authors in 108 women with history of hypertensive disorder of pregnancy (HDP)  between  the  10th  and  13th week of pregnancy to identify those at higher risk for recurrent preeclampsia and to evaluate the efficacy of prophylactic pharmacological treatment in this subgroup of patients. Patients with abnormal flow values (RI > 0.58 and any notching) were immediately started on aspirin 100 mg/daily, replaced by daily subcutaneous injection of low molecular weight heparin from  the  24th week till delivery. Concerning the maternal morbidity (expressed by abnormal both mean blood pressure and 24-hour proteinuria throughout pregnancy), the Authors found  that  the average pregnancy course in 20 (18.5%) prophylactic treated patients with altered 1st trimester UADV (group A) was better than in their previous pregnancies, however regarding the above parameters no significant difference (P > 0.05) was found between the  patients  treated  and another cohort of patients (n =20), also extrapolated from the same pool of patients at risk for HDP, but with normal I trimester UADV studies (group B) who were not prophylactic treated. Both groups of patients were followed up from the time of Doppler studies till 6 weeks post partum. The study suggests that UADV in the late first trimester of pregnancy is  useful  in reducing the risk of preeclampsia in patients with history of HDP, allowing  the  prompt  institution of prophylactic treatment in selected patients.

Abstract :

The effects of curcumin pretreatment to negate chromate (VI)-induced cytotoxicity and oxidative stress was evaluated in vitro on human peripheral blood lymphocytes and murine macrophages RAW 264.7.  Chromate treatment at a dosage of 10µg/ml resulted in significant immunosuppression evident from the severe growth inhibition and cytotoxicity in both lymphocytes as well as macrophages which is revealed by MTT assay and LDH leakage. A   decrease in the percentage phagocytosis, phagocytic index and depleted glutathione status was also observed in the macrophages subjected to chromate treatment. In addition to this, chromate treatment resulted in an increase in fragmented DNA (quantified by colorimetry) in the lymphocytes suggestive of severe cellular stress and apoptotic cell death. Curcumin pretreatment at a dose of  20µg/ml was able to protect both lymphocytes and macrophages against chromate induced toxic effects as evidenced by the increase in percentage survival and cell viability, increased percentage phagocytosis, phagocytic index and improved thiol status in the macrophages  concomitant with a decrease in fragmented DNA in lymphocytes.  This shows the influence of curcumin to ameliorate the altered immune responses and adverse changes induced by treatment with hexavalent chromium. The results of the study reveal the beneficial effects of curcumin supplementation to negate the toxic changes induced by chromate (VI).

Abstract :

The main objective of the study is to provide a new insight on customer expectations over the services offered by LIC. This study finds out the policy holders opinion regarding various aspects like skills and competency of employees, service delivery process, technological capability of the organisation and claim settlement method. Both Primary and secondary data were used for this study. Primary data was collected from existing policy holders of LIC. Samples of 150 respondents was collected from three different branches in  Pudukkottai  district. Simple Random Sampling method is adopted for the collection of the information. Descriptive Statistics, correlation analysis were used for this study and their results was interpreted. LIC can offer more attractive products with low premium rate in order to compete among private insurer. It could be suggested that though LIC holds its power in creating trust and instilling confidence in the minds of the policyholders, but lacks in various service delivery aspects such as solving problems, providing prompt delivery of services and responses to the policyholders. LIC may focus on the efficient and effective delivery of services to the policyholders which would enhance corporate goal of increasing insurance coverage, more profit and increment in market value and share.

Abstract :

In this paper, we assess the key determinants of economic growth in Zambia between 1973 and 2013. In this view, a model is developed to assess investment, infrastructure development, economic diversification, and human development. Following the endogenous growth theories which postulate that policies play a substantial role in advancing growth on a long-run basis, we make use of exploratory data analysis techniques, multiple regression analysis and statistical tests to model economic growth as a function of foreign direct investment, construction, exports of goods and services and gross national income per capita power parity. We find that the real domestic product increased four times per unit increase in foreign direct investment, and the gross national income has a one-to-one correspondence with economic growth.

Abstract :

An investigation was conducted at the National Root Crops Research Institute, Umudike in South eastern Nigeria involving nine sweetpotato landraces and two Check varieties TIS87/0087 and UMUSPO/3with the following objectives: to evaluate the diversity that exists in  the selected sweetpotato landraces and to conserve them for future usage, to identify parents that flowers and are resistance to pests and diseases of ecological origin, to select landraces in terms of high storage root yield, high dry matter content and to build up reserve of breeding materials of native species that have nutritional and industrial potential for crop improvement programme. The results indicated that variability existed among the selected sweetpotato landraces and that the significant (P<0.01) highest fresh storage root yield of 19.6t/ha was for the landrace Kwara followed by ABCHI with 19.4t/ha and which were above the two standard check varieties (87/0087 and UMUSPO/3 which yielded 17.9 and 17.1t/ha respectively of fresh root yield) in the two years combined qualified them to be selected for registration and for commercial sweetpotato production. The landraces have high dry matter content of 33.4 and 31.2% respectively which is good for industrial and domestic utilization. They are also resistant to major field pests and diseases of sweetpotato (score 1) and could be selected for inclusion in the sweetpotato germplasm for breeding purposes. The two landraces flowers and have moderate (0.47 for ABCHI) to high (0.51 for Kwara) harvest index, although lower than the two checks (1.70 for UMUSPO/3 and 0.53 for TIS87/0087) however, it was an indication of high photosynthetic efficiency per unit area. The root morphological characters of the landrace ABCHI (and other landraces collected from Abia State) have similar root biological ranking with TIS87/0087, and may be regarded as duplicate of TIS87/0087. These landraces are quite distinct from Kwara, Ex-Igbariam, UMUSPO/3 and Buttermilk. The characterization enables for an easy and quick discrimination between the landraces. The characters discriminated upon are generally highly heritable and can easily be seen by the eyes and are equally expressed in all environments. These characters were potential attributes for recognizing them for biodiversity conservation, crop improvement and for  registration as official varieties in Nigeria.

Abstract :

We investigated in this paper the stabilizing effects of warm plasma and a strong HF electrical field on a two-stream (Buneman) instability in a plane and cylindrical plasma waveguide. Starting from the two-fluid plasma model to separate the problem into two parts, temporal and space. Plasma electrons are considered to have a thermal velocity. It is shown that independent of the geometry of the problem the conclusion on the HF stabilization of Buneman instability in a plasma waveguide remains valid and the growth rate of the instability in warm plasma has been reduced compared to that of cold plasma.

The influence of HF electric field on the instability of a low-density electron beam passing through warm plasma waveguide is also reported.
