  This paper studies the relation between inflation rates and its uncertainty by using Markov-Switching regression model and monthly data of consumer price index during 1990:01-2012:09 in Iran. Inflation uncertainty is estimated by using Generalized Autoregressive Conditional Heteroskedastisity (GARCH) model. The empirical results of Markov Switching Auto Regressive (MSAR) model represent the presence of two clearly differentiated regimes over the entire Sample. The first regime corresponds to a high level inflation rate, low volatility, and the second regime corresponds to low level inflation, high volatility. The use of Markov-Switching Regression Model indicates that the increase of inflation rate will be associated to higher uncertainty according to both regimes.   Manuscript profile

       In order to determine the best rate of nitrogen and row spacing of rapeseed, Hyola 308, this research work was carried out in paddy field of RRII  (Rasht, Iran) during 2004 – 2005. A factorial experiment was performed based on RCB olesign with three replications. The treatments were row spacing at three levels: 20, 25 and 30 cm and four nitrogen fertilizer rates: 0.7, 1.0, 1.3 and 1.6 R from urea source, based on soil testing and soil and water research institute recommendation. The R factor was 140 kg urea/ha. In this research work, some important agronomical traits such as number of pods per main stem, number of pods per auxiliary branches, number of pods plant, number of seeds per main pod, number of seeds per auxiliary pod, number of seeds per pod, 1000  seed weight, grain yield, oil percent and oil yield were studied. The results of analysis of variance showed that non significant differences exist between row spacing for grain yield. However, row spacing of 20 cm was relatively superior with an average grain yield of 1908 kg/ha.  Interaction between row spacing and nitrogen rate on grain yield was non significant. Fertilizer rate of 1.6 R and row spacing of 20 cm with average 2291 kg/ha had maximum grain yield. Interaction between row spacing and nitrogen rate on oil yield was non significant but row spacing of 20 cm and fertilizer rate of 1.6 R showed maximum oil yield.       Manuscript profile

       In order to study of  different    effects  of  seed  rates  and nitrogen  levels  at  the  booting stage on  the   grain yield and yield components of N-81-18 line at the different conditions of  Mazandaran clime experiment as split- plot at the random complete Blocks design at the four replication at 2009 -2010 year at two regions of Gharakhyl and the Farim was executed in the Sari and Ghaemshahr agent. Main plot includes 3 levels of seed rates (200, 250, 300 kg/ha) and sub plot has been included 3 levels of nitrogen at the booting stage (0-17.5, 35 kg of nitrogen or o-37.5, 75 kg from urea resource). Results showed that bending moment at the Gharakhyl region (height from sea level is 14.7 meter) then pharim region (height from sea level is 725 meter) because of shortest internodes height, culm height, the number of internodes, weight of culm wet and spike weight was less. With excess of seed rate to 300 kg/ha, bending moment for the most low weight of culm wet and spiek had reduction and nitrogen levels at the booting stage had not signification effect on the bending moment. Grain yield at the Farim region was 20.22 % more than Gharakhyl reason of this was increase of the number tiller on plant, the number of spike at the grand unit, increase of 1000-grain weight and the number grain at the spike. Grain yield with a lot consumption of nitrogen at the booting stage than without consumption of nitrogen increased 10.8 %. However seed rates was not signification effect of grain yield but was received the most and less number of spike at the grand level unit respectively as 300 and 200 kg, seed /ha. Manuscript profile

  7 - The Relationship between the Mobility of Sperm on Pregnancy Results by Intrauterine Insemination

  Intrauterine insemination (IUI) is the first line of infertile couple treatment for its inexpensive and non-invasive. There is a wide range of indications like infertility with male causes, cervical-associated causes, and unknown causes for intrauterine sperm injection. Meanwhile, the main parameters of sperm such as count, mobility, and morphology of sperm play a key role in the success of this method. One of the significant problems in the quality of sperm is the reduced mobility of sperms. Based on the WHO, the mobility under 50%, concentration over 20 million, and morphology over 4% are considered as Astenoaspermia.  This study was conducted on the effectiveness of mobility on the outcome of pregnancy with IUI among the infertile couples referring to Jahad Daneshgahi infertility center. A number of 215 samples were divided in three groups of mobility over 70% (normospermia), mobility between 50% and 70% (normospermia) and mobility under 50% (astenoaspermia). The sperms were prepared with SU. The studies indicated that on sperm mobility after preparing had significant increase in all groups. Ovarian stimulations were performed based on the international protocol and the prepared suspension sperm was injected slowly into the uterus with Catheter. The results of pregnancy in term of pregnancy rates, abortion rates, and birth rates were evaluated and analyzed statistically. The results indicated that mobility has no contribution in the significant increase of pregnancy outcomes due to intrauterine insemination. Manuscript profile
