The type, distribution and population of plant-parasitic nematodes on crops change over time and space. It is pertinent to know their current status to ensure effective management. A survey was carried out to determine the occurrence and population of plant-parasitic nematodes associated with cassava in the East Senatorial District of Rivers State, Nigeria. Multi-stage random sampling method was used to collect soil and root samples from 56 farms growing cassava in monoculture across four Local Government Areas.

Aims: To analyze the nutritional aspects, to characterize the socio-demographic profile, to categorize the types of Cerebral Vascular Accident most common in this population, relating to the life habits, comorbidities and nutritional risk in which the patient is. Methods: Descriptive cross - sectional study of a quantitative exploratory character with patients over 18 years of age diagnosed with stroke admitted to the adult emergency unit of a reference hospital in the northern region of Ceará between August and November / 2016.

Background: Thyroid hormones are important in the development of the fetus and the placenta as well as in maintaining maternal wellbeing. Thyroid disorders are common in the population as a whole, particularly in women, and therefore are common during pregnancy and the puerperium. Biochemical derangements of thyroid function tests are present in approximately 2.5–5% of pregnant women. In addition to adverse obstetrical outcomes; maternal hypothyroidism is associated with adverse neonatal outcomes.

This research introduces an innovative virtual keyboard system leveraging machine vision for human-computer interaction. The system utilizes hand tracking and recognition to facilitate virtual keyboard control without physical touch. This paper details the system architecture, implementation, and experimental results. This research introduces a novel approach to virtual keyboards using machine vision, providing an innovative and cost-effective solution for human-computer interaction.

Goal orientation refers to the goals individuals implicitly pursue while attempting to attain certain performance outcomes (Dweck & Leggett, 1988). In general, goal orientation has been conceptualized as the mental framework in which people interpret and respond to situations, circumstances and events of both achievement and failure. The data for this study was collected through survey method. Executives with more than 45 years of age have higher performance-approach and performance-avoidance. Further details were discussed in this paper.

Precancerous lesions such as leukoplakia possess a high risk of transformation into oral cancer. This can be prevented if they are diagnosed and treated in the earlier stages. Besides various available pathological investigations and molecular research works , attempts are also being made by computer analysts to find out a technique that could accurately diagnose and classify these diseases. One such attempt has been made in this research work by using SVM (Support Vector Machine) to classify leukoplakia lesions from normal oral mucosa.

Amongst all gynecological cancers, ovarian cancer is the most lethal malignancy worldwide, aggressive local invasion and the lack of sensitive early screening methods, poses the most difficult in early diagnosis, furthermore, its high mortality rate has made it one of the most investigated fields in gynecological oncology during this year in USA. The aim of the study is to assess the level of serum biomarker cancer antigen (CA-125), among ovarian cancer women at Khartoum State - Sudan.

In the present study we investigate the relationship among HSSW and SSSW with interplanetary parameters Dst and proton flow pressure for the time interval 2005 -2009. The present study investigates by means of stastical method employed for average values. The solar wind is classified into two categories- • High speed solar winds (HSSW) which have value > 450. • Slow speed solar winds (SSSW) which have value < 450. We got the emergence of charged particles from sun varies and the variation causes change in various solar activities.

The two ion-pair complex of Cyclizine (Cy) with sodium tetraphenyl borate (TPB) and Phosphotungstic acid (PT) was prepared and used for the construction of Cy-selective electrode. The electrode based on the Cy-PT ion-pair complex has a lower detection limit of 1.5 x 10-7 M in a linear concentration range of 3.5 x 10-7 – 1.0 x 10-2 M with a slope of calibration curve of 50.5 mV/decay. The selectivity coefficient was calculated with separate solution method dictates the high selectivity of the electrode over other tested ions.

The main purpose of this research paper is to examine the relationship between the impact of Management Styles and the Job Satisfaction in the Plantation Sector in Sri Lanka. There are 5 items of construct to measure management style (MS) and five sub constructs for each construct to study the MS. The five main constructs are namely participatory management style (PAMS), organic management style (ORMS), professional management style (PRMS), coaching management style (COMS) and Samsung management style(SSMS).MS will be one of the two main variables investigated in this study.
