This study presents the intercomparison of the outdoor environmental gamma dose rates measured using a Nal （TI） based survey meter along with thermoluminescent dosimeters （TLDs） and estimation of excess lifetime cancer risk （ELCR）, for the inhabitants of Poonch division of the Azad Kashmir, Pakistan. CaF2： Dy （TLD-200） card dosimeters were installed at height of 1 m from ground at fifteen different locations covering the entire Poonch division comprising of three districts.

In practice,the control charts for monitoring of process mean are based on the normality *** the performance of the control charts is seriously affected if the process of quality characteristics departs from *** such situations,we have modified the already existing control charts such as Shewhart control chart,exponentially weighted moving average(EWMA)control chart and hybrid exponentially weighted moving average(HEWMA)control chart by assuming that the distribution of underlying process follows Power function distribution(PFD).By considering the situation that the parameters of PFD are unknown,we estimate them by using three classical estimation methods,i.e.,percentile estimator(P.E),maximum likelihood estimator(MLE)and modified maximum likelihood estimator(MMLE).We construct Shewhart,EWMA and HEWMA control charts based on P.E,MLE and *** have compared all these control charts using Monte Carlo simulation studies and concluded that HEWMA control chart under MLE is more sensitive to detect an early shift in the shape parameter when the distribution of the underlying process follows power function distribution.

Chalcone derivatives are of immense importance owing to their superior pharmacological profile. Minor changes in their structures create high degree of diversity that results in a broader spectrum of biological activities. The present research paper presents the synthesis of 3-（4-chloro-3-nitrophenyl）-1-phenylprop-2-en-1-one chalcone（I）, single crystal XRD analysis and the evaluation of its possible biological activities like cytotoxic（LD（50） = 5.40 ug/m L）and antileishmanial（LD（50） = 0.81 ug/m L） activities. The results indicate the tested chalcone（I）shows superior inhibition values against leishmanial promastigotes. Further, the possible interaction sites of chalcone（I） with Try R enzyme involved in the redox metabolism of the leishmanial parasite were determined using docking simulation technique. Docking computations demonstrate that the compound establishes prominent binding interactions with the key residues of Try R and possesses the potential to effectively inhibit the catalytic activities of enzyme. Thus the results suggest that the chalcone（I） can serve as a potential scaffold for the treatment of leishmaniasis and deserve further development.

Paediatric-appropriate facilities in emergencydepartments of community hospitals in Ontario：A cross-sectional study

World Journal of Emergency Medicine 2017年第4期8卷 264-268页

BACKGROUND: We assessed whether the paediatric-appropriate facilities were available at Emergency Departments(ED) in community hospitals in a Canadian ***: We conducted a cross-sectional survey of EDs in community hospitals in Ontario, Canada that had inpatient paediatric facilities and a neonatal intensive care unit. Key informants were ED chiefs, clinical educators, or managers. The survey included questions about paediatric facilities related to environment, triage, training, and staff in ***: Of 52 hospitals, 69%(n=36) responded to our survey. Of them, 14% EDs(n=5) had some separated spaces available for paediatric patients. About 53%(n=19) of EDs lacked children activities, e.g., toys. Only 11%(n=4) EDs were using paediatric triage scales and 42%(n=15) had a designated paediatric resuscitation bay. Only half of the ED(n=18) required from their staff to update paediatric life support training. Only 31%(n=11) had a designated liaison paediatrician for the ED. Paediatric social worker was present in only 8%(n=3) of EDs in community ***: Most of the Ontario community hospital EDs included in this survey had inadequate facilities for paediatric patients such as specific waiting and treatment areas.
