- چکیده:
- چکیده انگلیسی: Purpose: The present study aims at describing the general status of non-resident agriculture holders in rural areas. Moreover, it tries to not only investigate the hotspots of non-resident agriculture holders but also analyze its spatial pattern across the county of Iran. Besides, the current study will analyze the most effective factors on forming each hotspot across the Country.
Methods: The study is a kind of descriptive-analytic one. The data are adopted from agriculture census of Iran Statistic Center in 2003 and 2014. They have been analyzed by spatial statistic techniques in GIS environment.
Results: The findings reveal that the spatial distribution of non-resident agriculture holders is heterogeneous across the Country. The findings from spatial statistics indicate the existence of two main hotspots of non-resident agriculture holders across the towns; the first hotspot has been formed in central Iran and the northern regions of the Country, while the other one has been formed in the west.
Conclusion: The increase of non-resident agriculture holders in rural area which has been formed in the frame of rural-urban linkages, leads to increase smallholdings, decrease agriculture productivity, and weaken the balance between rural population and agriculture capacities for production and employment. Therefore, it acts like a barrier in the process of Sustainable rural development.- انتشار مقاله: 01-07-1398

- چکیده:
- چکیده انگلیسی: Background & aim: Based on the previous reports, treatment with 17 α-Hydroxyprogesterone caproate (17-OHPC) decreased the risk of preterm labor (PTL). However, some studies indicated contrasting results. This study aimed to investigate the effect of 17-OHPC on the prevention of PTL.
Methods: This randomized controlled trial was performed on singleton pregnant women with a history of PTL referring to Imam Khomeini Hospital, Sari, Iran. The experimental group was subjected to an intramuscular weekly injection of 250 milligrams of 17-OHPC from week 16 to 37 of gestational age (n=50). The control group received routine prenatal care. Data were collected using a self-structured checklist, and analyzed using SPSS software (version 18) through independent T-test, Mann-Whitney U test, and the Chi-square test.
Results: The mean age of the experimental and control groups were 24.4±2.6 and 25±2.38 years, respectively. According to the results, there were no significant differences between the groups regarding the risk of PTL less than 35 and 37 completed weeks (P=0.21, P=0.23). Furthermore, a significant relationship was observed between the use of 17-OHPC and birth weight (P<0.05). The frequency of birth weight less than 2500 g in the experimental group was significantly lower than that in the control group (RR:1.56, 95% CI:1.6-2.29, P=0.023).
Conclusion: The results of the outcome analysis based on the separation of gestational age and birth weight in the case and control groups showed no significant differences between the groups regarding the risk of PTL less than 35 and 37 completed weeks.- انتشار مقاله: 19-01-1398

- چکیده:
- چکیده انگلیسی: In the current investigation a novel nano hybrid adsorbent MCM-41/N-(3-trimethoxysilyl)-propyl)diethylenetriamine (MCM-41/TMSPDETA) was prepared and was characterized using DLS (Dynamic Light Scattering), Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analytical techniques and Transmission electron microscopy (TEM). The synthesized MCM-41/TMSPDETA adsorbent possessed high surface area (867 m2g−1), narrow pore size distribution (3.6 nm) and pore volume (0.782 cm3g−1). The nano hybrid adsorbent was applied in batch experiments under different controlling factors by varing pH, contact time and solution temperature of Lead (Pb(II)) and Nickel (Ni(II)) ions. Optimum conditions obtained were 20°C, pH=6 and contact time of 120 min. The maximum capacity of the nano-sorbent was obtained to be 58.823 and 20.921 mg g−1 for Pb (II) and Ni (II) ions for an initial concentration range 10-70 mgL-1. Pseudo-first order, pseudo-second order and intraparticle diffusion models were used to analyze the kinetic data. Results showed that the pseudo-second order model can well describe the adsorption kinetic data.
