A topological space is said to be almost regular closed Lindeloff (=ARC-Lindeloff) if every cover by regular closed sets has a countable subfamily whose union is dense. In this paper we investigate properties of ARC-Lindeloff. In addition, several example will be provided to illustrate our results.

The CCC-r chart is developed based on cumulative count of a conforming (CCC) control chart that considers the cumulative number of items inspected until observing r nonconforming ones. Typically, the samples obtained from the process are analyzed through 100% inspection to exploit the CCC-r chart. However, considering the inspection cost and time would limit its implementation. In this paper, we investigate the performance of CCC-r chart with variable sampling interval (CCC-rVSI chart). The efficiency of CCC-rVSI chart is compared with fixed sampling interval (FSI) scheme of CCC-r chart (CCC-rFSI chart) and CCCVSI chart. The comparison results show that CCC-rVSI chart is more efficient than the CCCVSI chart in reducing the average time to signal (ATS) and also CCC-rVSI chart performs better than CCC-rFSI chart. In addition, some sensitivity analyses are performed to illustrate the effect of the input parameters on the performance of CCC-rVSI chart.

A field experiment was conducted to evaluate the effect of planting density and cycocel (2-chloroethyl trimethyl ammonium chloride) CCC application and yield components of wheat (cultivar Cross Azadi) in Islamic Azad University of Arsanjan, in 2009-2010. The experimental design was RCBD. Treatments included planting density (100, 250, 400 and 550 plants in square meter) and chlormequat chloride concentrations: (0 and 2.5 l/ha-1). Results showed that chlormequat chloride applied caused to increase significantly grain yield, biological yield, spiklet/ear, 1000-grain weight, number of spikes m-2, number grain of spikes and harvest index compared with the control. Application of Chlormequat chloride decreased significantly plant height and infertile tillers per plant compared to the control. Increasing plant density increased spikes m-2 biological yield, Grain yield, plant height, die tillers per plant and harvest index than Density 550 plant in square meter with applied chlormequat chloride has the highest grain yield than other densities and density 100 plant in square meter has the lowest grain yield. Plant density of 550 plant m-2 and chlormequat chloride application is recommended for conditions similar to the present investigation.

In today's highly competitive industrial environment due to fast technology development, quality practitioners will have to detect out-of-control situations and take actions whenever is necessary as soon as possible. Accordingly, new statistical procedures have been enhanced incessantly both to handle high yield processes along with looking for methods of minimizing all quality cost. CCC-r (Cumulative Count Conforming-rarely) chart, the extended method of CCC charts, is commonly applied when nonconforming items are rarely observed. Since the values of the parameters used for the design of the charts' control parameters are usually unknown in practice, the practitioners need to estimate them by using an in-control retrospective sample. It has been shown that parameter estimation affects the control charts' properties severely. This study develops a model based on estimation costs and Average Number of Inspected Items for CCC-r chart when nonconforming fraction is unknown. The unknown parameters estimated based on different values of sample sizes and sensitivity analysis was performed.

Introduction: Standardized tests in speech therapy mostly focus on language structure rather than the use of language in social context. So, there is a clear need for instruments that assess pragmatic aspects of language. Children are Communication Checklist (CCC) and its revised version, CCC-2, were developed to address this need, however, its psychometric features are unknown in Iran. The current study aimed to adapt the CCC-2 for 7-9 year old Persian speaking children by testing its content validity and two types of reliability, internal consistency and test-retest.Materials and methods: This study is a non-experimental validation study. In the process of determining content validity, back translation was performed by three experts in fields of linguistic and speech, language therapy (SLT). Also, 28 parents of seven to nine years old children with normal language development involved to judge about the simplicity and comprehensibility of the items. The translated form, then, was sent to 10 linguists and SLTs to judge about its content and finally content validity index (CVI) were computed for each item. Internal consistency and test-retest reliability were determined by asking the parents of 100 children between seven and nine years old to complete the form.Results: All items but four were found with a CVI higher than .85. After revision, the CVI scores of the remaining four items were improved. Content validity index was found higher than .75. Internal consistency for each of the items were found between .66 and .74. Test-retest reliability was established higher than .90within two weeks interval.Conclusion: Results suggested that the Persian adaptation of CCC-2 possesses an acceptable content validity and reliability for 7 to 9 year-olds. Its psychometric values, however, need to be improved by conducting further studies on larger sample sizes and across other ranges of age.

Increasing plant density is often associated with lodging, hence decreasing photosynthesis efficiency and grain yield. A field experiment was conducted to evaluate the effect of three plant densities 30, 50 and 70 p/m2 and three different chlormequat chloride concentrations:0, 1.4 and 2.8 l/ha on some morphological characteristics and grain yield of winter rape seed (cv.Talayeh). The study was conducted under Bajgah agroclimatic conditions in a silty clay loam soil, Shiraz, Iran. The experimental design was a randomized complete block with four replications. The results indicated that, increasing plant density from 30 to 70 p/m2caused a significant increase in plant height (p<5%). When chlormequat chloride was applied at the rate of 1.4 l/ha at plant density of 70 p/m2 plant height was significantly decreased. Meanwhile the stem diameter and grain yield of plants treated with 2.8 l/ha chlormequat chloride at plant density of 70 p/m2 increased significantly. Although, the inter-nodes length and plant dry weight of the chlormequat -treated plants were smaller than control, their differences were not significant. It was conducted that under similar conditions to the present study, cv. Talayeh with plant density of 70 p/m2, and foliar application of chlormequat chloride at the rate of 2.8 l/ha can be used to achieve the highest grain yield.

To evaluate effect the of chlormequat chloride growth moderator (CCC) on some quantitative charachteristics of 5 peanut genotypes under normal irrigation and drought stress conditions and determine the effect of CCC in drought tolerant cultivars, an experiment was carried out in the spring of 2008. Treatments were arranged as factorial including CCC (0, 2 and 4 mg/lit) and 5 genotypes of peanut on the basis of Randomized Complete Block Design with 3 replications. This experiment was conducted at two irrigation regimes (drought stress and normal irrigation), separately. Results showed significant interaction between cultivars and CCC on all determined characteristics. The Maximum pod yield of 2860 kg/he was obtained from ICGV92071 and 2 mg/l CCC in normal irrigation while the maximum value of that was obtained from ICGV93420 and 4mg/l CCC in stress condition. ICGV93420 figure under drought stress conditions for both traits of ripe pod weight and number of branches and splits for non-stress conditions, performance characteristics and weight of ripe pods showed the highest value.

To evaluate the growth regulatory effect of chlormequat chloride (CCC) under drought stress conditions on three barley cultivars, a field study was conducted under Badjgah agro climatic conditions (altitude 1810 m, longitude 52o46’, and latitude 29o50’) during 2003-2004 growing season. A randomized complete block based split- split plot of four replications was employed with two moisture levels (well watered and drought stress during the post anthesis period) as main plots, chlormequat chloride treatment placed in sub plots (control and 1370 g a.i. ha-1 at lemma primordium stage) and 3 barley cultivars (Reyhaneh, Karoon and Valfajr) as sub-sub plots. The results indicated that drought stress decreased the grain yield, biological yield and harvest index of barley cultivars. The effect of drought stress on yield components, except for the number of grains per spike, was significant. CCC enhanced grain yield under well watered conditions, however, under drought stress conditions it decreased the grain yield significantly. The number of spikes m-2 was increased in CCC-treated plants. Dry weight and leaf area decreased under drought stress conditions. Green leaf area and dry weight of CCC-treated plants were greater during post anthesis period. Although a deep understanding of the effect of CCC on grain yield under drought stress conditions needs more research and for longer periods, it became evident that the timely use of CCC in irrigated barley farms could result in to an increased grain yield.
