In this research, we estimate the survival function by using three
nonparametric estimation methods and is to the method of Kaplan and
Meier, the method Gaussian Kernel and method Weibull Kernel.
Depending on the method of simulation and a complet
e real data from
reality. Where we proposed a new method to estimate the survival
function is to use Weibull Kernel and choose a new value to the optimal
bandwidth, which have an important role in the estimation process.

This search includes doing an analytical study to show the
outcomes of introduse the Thiessen Polygon method in calculate
the flow out of node in water distribution system ، and doing the
hydraulic calculation based on the new method’s outcomes and
comparing these outcomes with field measurements which
conducted in several control points .
This study recruited 51 elders aged 53-74 to discuss their daily activities in focus groups. The transcribed discourse was analyzed using the Chinese version of LIWC (Lin et al., 2020; Pennebaker et al., 2015) for cognitive complexity and dynamic lan
guage as well as content words related to elders' daily activities. The interruption behavior during the conversation was also coded and analyzed. After controlling for education, gender and age, the results showed that cognitive flexibility performance was accompanied by the increasing adoption of dynamic language, insight words and family words. These findings serve as the basis for predicting elders' cognitive flexibility through their daily language use.
Due to it`s several properties of Trypsin as an active enzyme in treating wounds, the
aim of this study was to evaluate the efficacy of this material with traditional treatments in
treating dry socket.
Methods:132 patients (20-65 years old) partic
ipated in this study.
The patient were distributed randomly into two groups.
The first group (group 1) was treated with Trypsin whereas the other (group 2) was
treated with traditional technique .
Patients were monitored, to asses healing process, after 24 hours, 48 hourse, and after
1 week.
Results: 43,9% of group 1 and 10,6% of group 2 had no pain P<0,05,wereas 81,8%
of group 1 and 43,9% of group 2 didn`t present dry socket P<0,05. Concerning infection ,7
cases of group 1 and 11 cases of group 2 had infection of soft tissue P<0,05.
Conclusions :Pain, dry socket, and soft tissue infection was less in casese treated
with Trypsin comparing with cases treated with traditional technique.
