Image registration has been long used as a basis for the detection of moving objects. In this method spatial information is often ignored, and different motions from multiple moving objects cannot be efficiently modeled. Moreover, image registration is not well suited to handle occlusion that can result in potential object misses. Here proposes a new approach to address these issues. Video frames are first segmented into uniform regions, followed by the construction of RAGs to represent each frame.

We assessed the effectiveness of a computerized system for the planning and execution of floral induction in mango using plant growth regulators and water stress in commercial production areas of the Brazilian semi-arid region. The Microsoft Excel was used to perform the calculations following the methodology applied in northeastern Brazil for floral induction. To assess the efficiency of the computerized system, we compared the simulated and observed values using the "d" concordance index.

Fungi of the genus Trichoderma are able to act as agents to control the growth of pathogenic fungi that cause diseases in several cultivated plants. Therefore, this work aimed to select and test Trichodermaisolates capable of inhibiting, in vitro, the mycelial growth of soil pathogens. 50 isolates of Trichoderma spp. were tested against the pathogenic fungi Sclerotiumrolfsii, Rhizoctoniasolani and Fusariumsp. The in vitro culture pairing technique was used, with scores on grades according to the criteria proposed by Bell and percentage of colonization.

The banana, monocotiledônea belongs to the order Scitaminales, family Musaceae, subfamily Musoideae, genus Musa. Propolis is a resinous substance produced by bees through the collection of secondary metabolites of flora and its complex chemical composition and varied. Because of the fruit in natura are highly perishable, post-harvest losses represent a major problem, which can be minimized with the use of new methodologies in the harvest of fruits.

Introduction: The histological effects of Azadirachta indica (Neem) as a biopesticide, on the liver of Heteropneustes fossilis were determined. The histopathological changes induced in the liver were cytoplasmic vacuolization of the hepatocytes, blood vessel congestion, inflammatory leucocytic infiltration and necrosis. All these alterations in liver histology can be considered to monitor the water contaminated with biopesticides.

Systemic arterial hypertension is a public health problem that is difficult to control. Extrinsic and intrinsic factors consist of elements that hinder their diagnostic and medical follow-up. The present study aims to make an approach about the contributions of pharmaceutical attention in the control of the systemic arterial pressure of elderly patients. This is a qualitative, descriptive and exploratory study. For the research, a review of the scientific literature was carried out.

Background: Anaplastic thyroid carcinoma (ATC) is rare, but it is the most aggressive thyroid cancer. Cancer stem cells (CSCs), which have self-renewal ability and can generate multi-lineage cells, are potential causative agents for ATC recurrence. To assess the role of CSCs in ATC, we evaluated the sodium-iodide symporter (NIS or SLC5A5) and Phosphatidyl Inositol 3-Kinase (PI3K) mRNA levels in the (CD133pos) CSC fraction of ATC cell lines. Methods: Using magnetic cell sorting, we isolated (CD133pos) CSCs from three ATC cell lines.

Associated certifications of Geographical Indications is the traditional knowledge and food traditions, considering that studies on this subject are important objective to conduct a review of the literature on the laws and regulations on geographical indication.

The unprecedented success of social media combined with the availability of omnipotent multimedia capturing communication devices has promoted a fervid two way interaction between broadcasters and their perspective audiences. The social media success path to preeminence, however, has created disillusioned expectations for analogous results in the arena of digital broadcasting.

The study aimed to assess the vulnerability due to climate change (CC) of rural fresh water and sanitation (RFWS) – an interest issue because of its important role in life as well as sensitivity to CC effects; a case study in coastal area in Ho Chi Minh city, Vietnam (Can Gio district). By index method, applied for the first time in RFWS field, vulnerability (V) was evaluated through 51 indicators. They include 20, 12, and 19 indicators with their weights refecting exposure level (E), sensitivity (S), and adaptive capacity (AC) of the system, respectively.
