Abstract: Polymer compositions may include a polymer matrix containing a polyolefin, one or more polymer particles dispersed in the polymer matrix, wherein the one or more polymer particles include a polar polymer selectively crosslinked with a crosslinking agent, and wherein the one or more polymer particles has an average particle size of up to 200 ?m. Processes of preparing a polymer composition may include mixing a polyolefin, a polar polymer, and a crosslinking agent; and selectively crosslinking the polar polymer with the crosslinking agent in the presence of the polyolefin. Methods may include increasing stress cracking resistance of a polyolefin by mixing a polar polymer with the polyolefin; and selectively crosslinking the polar polymer in the presence of the polyolefin with a crosslinking agent to form crosslinked polar polymer particles dispersed in the polyolefin.

Abstract: The invention relates to the preparation of carboxylic acid esters compounds, biodiesel (B) from microalgae, for use as a biofuel for compression type ignition. The objective is achieved through a hydroesterification process of a microalgae biomass (MU) comprising a hydrolysis stage and the esterification stage by means of heterogeneous catalysis. The wet microalgae biomass (MU) is the result of a process of cultivation concentration and is hydrolyzed directly in a hydrolysis column (20). Fatty acids (C), water (A) and raw glycerin (G) are obtained following the hydrolysis. The fatty acids (C) are esterified by reactive distillation in the presence of an impregnated heterogeneous catalyst (I).

It presents selective cytotoxic effects particularly on mammalian human and nonhuman cells that divide constantly and are useful in treating diseases and dysfunctions related to the phenomenon of undesired cell proliferation. Such compounds are also effective for the treatment of diseases or dysfunctions related to high levels of TNF-? in human and nonhuman mammals.

Abstract: The proposed innovation relates to the biotechnological improvement of plant species of commercial interest. More specifically, the present invention relates to the production of transgenic plants biotechnological with greater tolerance to water deficit and salt stress by means of the expression of a new gene of coffee (of the Coffea Arabica species), belonging to the HD-Zip family, and characterized by a homeodomain associated with a leucine zipper. The expression of this transcriptional factor is induced in leaves and roots of coffee plants subjected to various water deficit conditions (both moderate and severe); transgenic plants that over-express this gene inhibiting greater tolerance both to differ drought intensities and to high salt concentrations.

Abstract: The present invention refers to the construction of cloning vectors containing the max gene. Especially, the present invention refers to the introduction of cloning vectors containing the max gene in cells using transport vectors. In addition, the presence of cloning vectors containing the max gene in cells allows the differential expression of the max gene in the same cells. In addition, the present invention refers to a method of gene therapy in which the differential expression of the max gene has cytoprotective activity, especially neuroprotective activity, and is capable of application to medical and veterinary therapeutics of neurodegenerative conditions.

Abstract: Preparation and use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, having activities in increasing gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-? levels and an exogenous source of nitric oxide, such as sickle-cell disease. The functionalized phthalimide derivatives are designed from the prototypes thalidomide and hydroxyurea.

Abstract: The present invention refers to a method for establishing a communication network that connects a group or community of users using wireless equipments according to their defined interests. These equipments are preferentially portable, low cost, and user-friendly, where each equipment must be configurable using its user's profile, which contains a small amount of the user's personal data, namely the miniprofile. The method uses a collection of such miniprofiles to transparently set a communication network among the associate users to establish a virtual community. In addition, each profile will contain further information on user's interests, which the method will propagate across the communication network to the established virtual community in a way that their members will be able to form groups based on common interests while allowing for interaction among their members. The user profile can be set identifiable or anonymous, may or not be shareable in relation to the other members of a group.

Abstract: A Distributed Video System provides a scalable and interactive video-on-demand service with VCR operations over a communication network includes a video server and video clients, each of which includes a memory buffer, called a client buffer. The System provides a method of managing video frames of client buffers in a cooperative way with video frames held in the video server allows the video frames of the client buffers to be shared among the video clients. Requests for a video are primarily served by the video clients that have the requested video frames in their client buffers and only requests that the video clients are unable to attend to will be provided by the video server.
