The canonball model, which unifies cosmic ray bursts (CRBs) and gamma (GRBs), is used to predict the maximum isotropic equivalent energy release in a GRB. predicted based on observed knee around 1 TeV spectrum of Galactic electrons, Amati correlation GRBs. Both were by cannonball model CRBs GRBs before their empirical discoveries. agrees well with that concluded from up date GRB observations.

Polymers are the backbone of a transdermal drug delivery system as they control the release of the drug from the device. Biodegradable polymers attracts the attention of its use as they can be degraded to non-toxic monomers and most important, a constant rate of drug release can be achieved from a biodegradable polymer based controlled release device. Natural polymers can be used as the means o...

objective(s):despite of wide range applications of polymeric nanoparticles in protein delivery, there are some problems for the field of protein entrapment, initial burst and controlled release profile.   materials and methods: in this study, we investigated the influence of some changes in plga nanoparticles formulation to improve the initial and controlled release profile. selected parameters ...

megaloporous controlled release tablets of diclofenac sodium (ds) were prepared with two kinds of granules. one of them is the restraining-phase matrix granule (rmg) and it controls the release rate of the drug. the other one is the soluble housing-phase matrix granule (hmg) and controls liquid penetration into the system. carnauba wax and eudragit l 100 polymers were used to constitute the res...

Abstract There are a growing number of Information Communication Technology (ICT) applications in cultural heritage. However despite funding constraints, projects often involve similar or even duplicate work carried out at the same site. This emphasizes the need for an enterprise whose purpose is to coordinate research projects in this field. The EPOCH programme has been established to address ...

One of the oldest arguments in the history of psychology is the Nature vs Nurture debate. Each of these sides have good points that it's really hard to decide whether a person's development is predisposed in his DNA, or a majority of it is influenced by this life experiences and his environment. As of now, we know that both nature and nurture play important roles in human development, but we ha...

Recreational fisheries are an important element of contemporary fisheries. Detailed information about the motivation and opinions anglers regarding catch-and-release fishing in post-communist countries, such as Poland, has not been widely available to date. The aim this study was fill gap. We obtained 936 survey questionnaires completed by from throughout Poland. mean annual catch a Polish angl...

The object of the following study is representation scientific and methodical foundation procedure validation means serum in vitro diagnosis basing on sample ELISA for semiquantification specific Chlamydia trachomatis IgM-antibodies. Validation characteristics (precision, diagnostic analytic specificity, sensitivity, relative linearity) were defined both at beginning release set expiration date...

background loss of motion is a well-known complication after elbow trauma and in severe cases, arthrolysis of elbow is the procedure of choice. the posterior approach might have some advantages especially in post-traumatic patients who have undergone the same surgical approach in the past. objectives the aim of this study was to evaluate the short-term outcomes of elbow arthrolysis through post...
