This work studied the electrical and thermal surface conductivity enhancement of polymethylmethacrylate (PMMA) clouded by double-walled carbon nanotubes (DWCNTs) and multi-walled carbon nanotube (MWCNTs) by using pulsed Nd:YAG laser. Variable input factors are considered as the laser energy (or the relevant power), pulse duration and pulse repetition rate. Results indicated that the DWCNTs increased the PMMA’s surface electrical conductivity from 10-15 S/m to 0.813×103 S/m while the MWCNTs raised it to 0.14×103 S/m. Hence, the DWCNTs achieved an increase of almost 6 times than that for the MWCNTs. Moreover, the former increased the thermal conductivity of the surface by 8 times and the later by 5 times.
The current study aimed to determine the relation between the lead levels in the blood traffic men and the nature of their traffic work in Baghdad governorate. Blood samples were collected from 10 traffic men and the age about from 20-39 year from Directorate of Traffic Al Rusafa/ Baghdad and 10 samples another control from traffic men too with age 30-49 year and they livedrelatively in the clear cities or contained of Very few traffic areas. The levels of lead in blood estimated by used Atomic Absorption Spectrometry.
The result stated that there is no rising of the levels of lead in blood of traffic men Lead concentration was with more a range from 14 ppm in Traffic police are not healthy They are within the permissible limits, Ap

Asthma is a chronic and complex condition of the respiratory tract, that occurs in both children and adults. Currently available medications have side effects; therefore, new therapies with fewer side effects are needed. Thus, present study was designed to evaluate the potential anti-asthmatic effects of alcoholic extract of Ammi majus on ovalbumin-induced asthma in mice. Forty-eight female Albino mice were randomly assigned to one of six groups with 8 animals each. Group I received distilled water as a negative control, Group II received ovalbumin as a positive control, Groups III and IV received Ammi majus orally at 64 and 128 mg/kg/day, respectively, with sensitization, and Groups V and |
Given the significant differences in gas accumulation modes, coal reservoir characteristics, and gas preservation conditions for ultra-deep coalbed methane (vertical depth > 3000 m, measured depth > 5000 m), their production characteristics, flowback patterns, and flow phase classifications also vary greatly. Additionally, there are limitations in the production technologies applicable to deep reservoirs. To explore the relationship between the production characteristics of deep coalbed methane and medium-shallow coalbed methane, as well as to investigate suitable technologies for deep coalbed methane, this paper uses Well Q1 as an example and conducts research and analysis based on reservoir engineering theory.
