1.  Comparison of 4-chloro-2-nitrophenol adsorption on single-walled and multi-walled carbon nanotubes 
The adsorption characteristics of 4-chloro-2-nitrophenol (4C2NP) onto single-walled and multi-walled carbon nanotubes (SWCNTs and MWCNTs) from aqueous solution were investigated with respect to the changes in the contact time, pH of solution, carbon nanotubes dosage and initial 4C2NP concentration. Experimental results showed that the adsorption efficiency of 4C2NP by carbon nanotubes (both of SWCNTs and MWCNTs) increased with increasing the initial 4C2NP concentration. The maximum adsorption took place in the pH range of 2–6. The linear correlation coefficients of different isotherm models were obtained. Results revealed that the Langmuir isotherm fitted the experimental data better than the others and based on the Langmuir model equation, maximum adsorption capacity of 4C2NP onto SWCNTs and MWCNTs were 1.44 and 4.42 mg/g, respectively. The observed changes in the standard Gibbs free energy, standard enthalpy and standard entropy showed that the adsorption of 4C2NP onto SWCNTs and MWCNTs is spontaneous and exothermic in the temperature range of 298–328 K.

2.  Effects of 5-Year Interventions on Cardiovascular Risk Factors of Factories and Offies Employees of Isfahan and Najafabad: Worksite Intervention Project-Isfahan Healthy Heart Program 
ARYA Atherosclerosis  2010;6(3):94-101.
Effects of 5-year interventions of Worksite Intervention Project from Isfahan Healthy Heart Program on cardiovascular risk factors of factories and offices employees were studied in Isfahan and Najafabad (intervention area) compared to Arak (control area).
We had especial interventions for nutrition, physical activity and smoking as well as hypertension and obesity screening systems in all offices and factories, and other risk factors screening systems whenever possible. Before and after the interventions, questionnaires containing demographic and other required data were completed for the two populations; height, weight and blood pressure (BP) were measured and a fasting and 2h blood sample was taken for the measurement of blood sugar (BS) and lipid levels.
The prevalence of hypercholesterolemia, hypertriglyceridemia and central obesity decreased, but low HDL increased in office staff (P < 0.01). Waist circumference, HDL and total cholesterol mean values decreased, and diastolic BP and fasting and 2h BS increased among the intervention group. In factory workers, the prevalence of hypertriglyceridemia and central obesity decreased, while low HDL prevalence increased in intervention group (P < 0.001). Mean values of waist circumference, HDL and total cholesterol, and triglyceride decreased significantly (P < 0.001), while diastolic BP and fasting BS increased.
It seems that Worksite Intervention Project has a protective effect on CVD risk factors in factories and offices employees. So, the modifiable project can be used as an applicable tool for health improvement in worksites which creates tangible changes in employees’ lifestyle.

3.  {6,6′-Dieth­oxy-2,2′-[2,2-dimethyl­propane-1,3-diylbis(nitrilo­methyl­idyne)]diphenolato}(2-eth­oxy-6-formyl­phenolato)cobalt(III)–ethanol–water (1/1/1) 
The asymmetric unit of the title compound, [Co(C23H28N2O4)(C9H9O3)]·C2H5OH·H2O, comprises one complex mol­ecule, a water mol­ecule of crystallization and an ethanol mol­ecule of crystallization, which is disordered over two positions with a ratio of refined site occupancies of 0.567 (10):0.433 (10). The CoIII ion is in a slightly distorted octa­hedral geometry involving an N2O2 atom set of the tetra­denate Schiff base ligand and two O atoms of 2-eth­oxy-6-formyl­phenolate. The H atoms of the water mol­ecule act as donors in the formation of bifurcated inter­molecular O—H⋯(O,O) hydrogen bonds with the O atoms of the hydr­oxy and eth­oxy groups with R 1 2(5) ring motifs, which may influence the mol­ecular conformation. The crystal structure is further stabilized by inter­molecular O—H⋯O and C—H⋯O inter­actions.

4.  {1,1′-[2,2-Dimethyl­propane-1,3-diylbis(nitrilo­methyl­idyne)]di-2-naphtholato}nickel(II) 
In the title Schiff base complex, [Ni(C27H24N2O2)], the NiII atom shows a slightly distorted square-planar geometry. The dihedral angle between the mean planes of the two aromatic rings is 6.16 (6)°. In the crystal, pairs of inter­molecular weak C—H⋯O hydrogen bonds link neighboring mol­ecules into a chain along the a axis. The crystal structure is further stabilized by two inter­molecular π–π inter­actions with centroid–centroid distances of 3.7252 (13) and 3.8323 (13) Å.

5.  Process evaluation of a community-based program for prevention and control of non-communicable disease in a developing country: The Isfahan Healthy Heart Program, Iran 
BMC Public Health  2009;9:57.
Cardiovascular diseases are the most common cause of mortality in Iran. A six-year, comprehensive, integrated community-based demonstration study entitled Isfahan Healthy Heart Program (IHHP) conducted in Iran, and it started in 2000. Evaluation and monitoring are integrated parts of this quasi-experimental trial, and consists of process, as well as short and long-term impact evaluations. This paper presents the design of the "process evaluation" for IHHP, and the results pertaining to some interventional strategies that were implemented in workplaces
The process evaluation addresses the internal validity of IHHP by ascertaining the degree to which the program was implemented as intended. The IHHP process evaluation is a triangulated study conducted for all interventions at their respective venues. All interventional activities are monitored to determine why and how some are successful and sustainable, to identify mechanisms as well as barriers and facilitators of implementation.
The results suggest that factory workers and managers are satisfied with the interventions. In the current study, success was mainly shaped by the organizational readiness and timing of the implementation. Integrating most of activities of the project to the existing ongoing activities of public health officers in worksites is suggested to be the most effective means of implementation of the health promoting activities in workplaces.
The results of our experience may help other developing countries to plan for similar interventions.

6.  μ-2,3,5,6-Tetra-2-pyridylpyrazine-κ3 N 1,N 2,N 6:κ3 N 3,N 4,N 5-bis­[(methanol-κO)(nitrato-κ2 O,O′)(nitrato-κO)cadmium(II)] 
The title complex, [Cd2(NO3)4(C24H16N6)(CH4O)2], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra-2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) Å. Each CdII center is seven-coordinated by three N-atom donors of tppz in one plane, by two O atoms nearly normal to this plane, and by two O atoms 0.393 (3) and 0.488 (3) Å from that plane. The two CdII ions are above and below the plane of the pyrazine ring of the tppz ligand, oriented with respect to the pyridine rings at dihedral angles of 38.01 (3) and 31.90 (3)°. The dihedral angle between the two pyridine rings is 41.11 (3)°. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules.
