Abstract
After scrutiny the problem of time in Persian verbs, the writers of present essay proceed to revise the usage of auxiliary and modal verbs and by putting forward and criticizing the paroles of writers of Grammar about this subject, reject the difference of these two verbs and expressing the similarities of them in language and showing that modal and auxiliary verbs have the same usage; Then by presenting the verb 'willing' as auxiliary (but not modal) verb in verbs like "would to go" and "was going to go" and etc. putting forward the existence of the time of "future in the past" in Persian language and compering it with some time with the same name in English language. The writers believe that the time "future in the past" is not only a time but in combination with other times it can create some new times in it's subset.

Habrobracon hebetor Say (Hymenoptera: Braconidae) as an ectoparasitoid of larval stage of lepidopterous pests is widely used in biological control programs. In the present research, the effect of field recommended doses of imidacloprid, indoxacarb and deltamethrin were studied on life table parameters of H. hebetor in pupal stage treatment. One hundred, two-day-old pupae were treated with 1 micro liter insecticide solution using topical method. The pupae were treated with acetone in the control. Thirty emerged adults in each treatment were transferred individually to a Petri dish along with a male for mating. Three last instar larvae of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) were presented to each female wasp daily as host. The numbers of eggs produced per female per day were counted until all of the females were dead. The gross and net reproductive rates in control, imidacloprid, indoxacarb and deltamethrin were 204.6, 207.7, 209.1 and 112.1 and also 75, 41.3, 64.6 and 14.9, respectively. Intrinsic rates of increase were estimated to be 0.215, 0.154, 0.205 and 0.14 female offspring/female/day, respectively. Deltamethrin and imidacloprid had the most adverse effects on life table parameters of H. hebetor. Intrinsic rate of increase was not significantly affected by indoxacarb. These findings indicated that indoxacarb was relatively safe for H. hebetor and could be an appropriate candidate in integrated chemical and biological control.

The potato tuber moth (PTM), Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), is an important pest of potato and other solanaceous plants. It is cosmopolite and oligophage that exists in most countries where potatoes are grown. Because of chemical treatment adverse effects, there is a necessity to find safe alternatives to synthetic insecticides. So, medicinal plants are promising since they are safe, inexpensive and effective. In this direction, potato tubers were dipped in 1 ml of 5% methanolic extracts of fumitory, licorice, lavender and oregano. The percentage of first larval penetration to tubers and oviposition-preference of mentioned medicinal plants was investigated on PTM. Subsequently, fumigant toxicity of essential oils of basil, european pennyroyal, lavender, mint and savory were investigated on P. operculella. Treated potato tubers by methanolic extract of lavender elicited the lowest percentage (19.3) of first larval penetration. Studying of oviposition-preference demonstrated that the largest number of eggs were laid on control and fumitory with 28 and 10 eggs after three days, respectively. Probit analysis of essential oils showed that the most effective oil was savory which exhibited LC₅₀ value on adults of PTM equivalent to 0.048 µL/L air.

Vitamin D is one of the essential metabolic and physiological processes in the human body. Generally all people need 200-600 IU daily (Koutkia, Chen & Holick 2001). Production of vitamin D in the skin depends on some factors such as age, skin pigmentation and the amount of ultraviolet B (UVB)) available. The amount of UVB radiation is affected by geographic location, season, time and level of atmospheric pollution. The highest amount of vitamin D is provided to sunlight exposure (Gartner & Greer 2003) as well as obtaining from oily fish, fortified foods and supplement. The recommended vitamin D receiving depends on age, gender and deficiency treatment (Dobnig et al 2008).
Despite excessive oral vitamin D intake cause toxicity (Koutkia, Chen & Holick 2001), excessive sunlight exposure cannot cause vitamin D toxicity because UVB converts excess vitamin D3 to biologically inert isomers (Holick 2007).
Different factors like physical inactivity, chronic acidosis, malnutrition, delayed puberty and mal-absorption effect on bone mineralized (De Schepper 1990).
Parathyroid hormone (PTH) compensate for reduced serum calcium with calcium absorption from the bones, causing bone deformities and that this action has been done through activating osteoclasts inhabit. Excessive activate osteoclasts inhabit can lead to osteoporosis and increased PTH and serum calcium or metastatic calcification (Holick 2007).
Severe vitamin D deficiency with corresponding elevations of PTH were reported in 88% of women who presented with muscle pains and weakness. Myalgia is generally the first manifestation of vitamin D deficiency(Glerup et al 2000). Vitamin D deficiency affects in all parts of the body (Gartner & Greer 2003).
The high prevalence of vitamin D deficiency in patients with unspecified origin musculoskeletal pain was observed in the existed evidence (Gartner & Greer 2003). These studies represent there is significant relationship between unspecific pain and vitamin D deficiency that this relationship is independent of age group (Gartner & Greer 2003).
There is a strong relationship between vitamin D deficiency and persistent non-specific musculoskeletal pain. Therefore, the patients who suffering from unknown origin pain may be required to control their serum levels of vitamin D consequent to vitamin D therapy (Mascarenhas & Mobarhan 2004).
Studies have also shown that vitamin D therapy could improves extensive clinical complains regarding their bone pain and muscle weakness of women who referred to different clinics (Torrente de La Jara, Pecoud & Favrat 2004).

The Bird cherry-oat aphid, Rhopalosiphum padi (L.) is a serious threat to several cereal crops. Host-plant resistance to this aphid could be especially valuable in cereal crops pest management. Therefore, we evaluated the development, survivorship, reproduction and population growth parameters of R. padi as resistance indices among six wheat cultivars, including Gaskojen, Tajan, Falat, Saysonz, Kras and Sardari at 25 °C under laboratory conditions. The development time and fecundity of aphid differed significantly among the tested wheat cultivars. The r_m values were highest for aphids reared on Sardari and lowest on Gaskojen and intermediate on Tajan, Saysonz and Kras cultivars. Aphid showed the longest development time and the lowest fecundity, reflecting in the lowest r_m value on Gaskojen cultivar. Consequently, Gaskojen showed more positive characteristics and was relatively not susceptible cultivar that could be considered for planning a comprehensive IPM program of R. padi.

The concept of Quranic phrase بَعُوضَةً فَمَا فَوْقَهَا" : a gnat or a larger entity" has been always the subject of dispute among interpreters and translators of the Holy Quran. Apparently, the word "فوق: above" is not used in its common sense (higher and larger), rather, used in the parable sense, i.e. the opposite meaning "lesser and lower". The current study, applying an analytic-descriptive inquiry, using linguistics and referring to lexics, syntax, interpretation books, and considering the differences of words "«فـ»، «ما»، «فوق» : above, anything, or, respectively" based on intertextuality relations, assessed such implications in  words of Islamic grandees (Hadith of the holy Prophet, Imam Ali, and Imam Kazem). The phrase has been neglected due to the intertextuality to get the meaning of the verse, and has been interpreted as "larger and higher". Also with regard to intertextuality of this Quranic phrase and assuming a phrase from Sermon 164 of Nahjo- al-Balagheh, it is indicated that " فـَ" in this phrase means " إلی : to " and should be translated as«تا»  in Persian, implying an ascending trend. Moreover, reviewing many Persian translations of this phrase and providing the diagrams, it is revealed that the word«فوق»  in Persian does not certainly tolerate two opposite meanings (in any case), and accordingly, only some translations remain faithful.

Ferdowsi's Shahnameh has always been interest of readers, and many authors have tried to imitate it. Like other Iranian orators, the Kurd poets have recreated different stories of Shahnameh with innovations and sometimes translations. No doubt, the introduction and thinking of the epic verses after Shahnameh can expose some of the important issues of this valuable work and be effective on the morale of unity and patriotism among Iranian ethnic groups; therefore, in this study, we first introduced the verse of "Kordish Shahmghal and Rostam" and then compared it with the narration of " Shahnameh's Rostam and Shaghad", Salby's historical narratives, Toomar Naghali Shahnameh, Haft Lashkar, and Ferdowsinameh.

Safety is one of the main requirements of communities nowadays. Urban planners and designers have to distinguish unsafely factors in urban environment. The main aim is to increase the safety sense in urban space that is used by all people. Women consistently express greater fears for their personal safety in urban environments than do men. They need special requirement in urban environment in order to increase their perception of safety in urban public space such as parks. This study aims to survey women’s perception of safety of public spaces in Shiraz city (Iran). The data were gathered through a questionnaire. The study space selected for the research is Azadi Park, one of the main parks of Shiraz city. The results showed that there is a directed relationship between women’s sense of safety from land use, traffic and place neighborhood. The findings also showed that the rate of traffic, mix use of locations and places around the park and many space usages such as police office and station as welles religious places would increase the sense of safety. Personal factors (age, education, job and nation) had no relationship with the sense of safety.

Rosy apple aphid, Dysaphis plantaginea (Passerini), with worldwide distribution is an important pest of apple orchards. Host plant resistance is an essential component of integrated management of this insect pest. We investigated the resistance of seven apple cultivars, Malus domestica (Borkhausen), namely Granny Smith, Starkrimson, Golden Smoothee, Red Delicious, Golden Delicious, Boshghabi, and Shaki to rosy apple aphid under field and greenhouse conditions. The damage level by rosy apple aphid was significantly different among the tested cultivars precisely three weeks after infestation in both field and greenhouse conditions. The least leaf curling was observed on Shaki, while the most deformation was detected on Golden Delicious. There was positive correlation between damage in greenhouse and field studies. In addition, the lowest and highest numbers of aphids were observed on Shaki and Golden Delicious, respectively. Consequently, our results demonstrated that among the cultivars tested the Shaki cultivar is moderately resistant to rosy apple aphid and has the potential to be used in the integrated management of this aphid.

Aims: Streptococcus mutans (S. mutans) is part of human oral cavity microbiome and is known to be responsible of dental caries. The aim of this study was to evaluate the inhibitory effects of Punica granatum, Ricinus communis, and Allium sativum extracts on biofilm formation caused by S. mutans.
Materials and Methods: In this experimental study, the biofilm formation was carried out by broth dilution method with glucose -supplemented Tryptic Soy Agar (TSB) in 96-well microtiter plates. Seven serial dilutions from the aqueous extracts of the Punica granatum, Ricinus communis, and Allium sativum were prepared. Then, a suspension of S. mutans was added to the wells. The anti-biofilm effects of the extracts and turbidity were measured by an ELISA reader apparatus at OD₄₉₂nm. Experiments were completed in triplicate.
Findings: Ricinus communis was more active on S. mutans than other extracts. In comparison with others, the mean OD obtained in the presence of a concentration of 50mg of the plant extract (OD=0.083) was close to the negative control (OD=0.068). This plant was effective in higher concentrations (50, 25, 12.5 and 6.25mg/ml). Allium sativum extract has a moderate effect on S. mutans. The lowest activity belonged to Punica granatum extract.
Conclusion: The extract of Ricinus communis has strong anti-biofilm activity against Streptococcus mutans, when compared to other extracts, Allium sativum extract show moderate activity on the biofilm formation. Aqueous extract of Punica granatum peel isn’t very effective on S. mutans.

Biological and demographic parameters of the mealybug ladybird, Cryptolaemus montrouzieri (Mulsant) were evaluated on citrus mealybug, Planococcus citri (Risso) and obscure mealybug, Pseudococcus viburni (Signoret) under 24 ± 2 ºC, 80 ± 5% relative humidity and a photoperiod of 16:8 (L: D) h. The mealybugs had a significant effect on developmental time and reproductive and demographic parameters of the ladybird. Life span (egg to adult death) was obtained 220.85 ± 5.78 and 119.44 ± 2.1 days when fed on Pl. citri and Ps. viburni, respectively. However, mean number of eggs per female (fecundity) and mean percent of egg hatching were significantly higher on Ps. viburni than on Pl. citri. In addition, values of intrinsic rate of increase (r_m), finite rate of increase (λ) andnet reproductive rate (R₀) were significantly higher on Ps. viburni than on Pl. citri.The values of intrinsic rate of increase were estimated 0.081and 0.094 day^-1 on Pl. citri and Ps. viburni, respectively. Results of this study suggested that the obscure mealybug is a more suitable prey than the citrus mealybug as the ladybird displayed shorter developmental time, and higher fecundity and growth rate when fed with obscure mealybug.

Aim: Certain Mycoplasma species, the smallest and simplest free-living bacteria which lack a rigid cell wall, are considered as important pathogenic organisms in human and recognized to have a role in rheumatoid arthritis. The aim of this study was to use molecular methods to detect Mycoplasma spp. in synovial fluid of patients with reactive arthritis in comparison with patients suffering from non-inflammatory arthritis as a control group.
Materials & Methods: Synovial fluid samples were collected from 99 patients with arthritis, all of which fulfilled the standard criteria of American College of Rheumatology for the diagnosis of inflammatory arthritis (59 patients) or non-inflammatory arthritis (40 patients). The DNA of all synovial fluid samples was extracted, and PCR was performed with a specific set of general primers for 16S rRNA of Mycoplasma genus. The PCR products were confirmed via restriction enzyme digestion using BamH1 and sequencing.
Finding: A total of 11 out of 99 (11.1%) samples of patients with reactive arthritis revealed a 270bp amplification band. Digesting the PCR product of 16S rRNA by BamH1 confirmed the PCR assay. The sequencing also confirmed the amplified products.
Conclusion: The pathophysiology of inflammatory arthritis could be attributed, at least in part, to the persistence of bacterial DNA in the joint of patients with reactive arthritis.

Lady beetles are the most important predatory species among arthropods, so studying their population parameters gives a clear picture about their life span. The life histories of variegated lady beetle, Hippodamia variegata (Goeze), fed on the English grain aphid, Sitobion avenae Fabricius, on different host plants were studied under laboratory conditions, at 25 ± 1 °C, 65 ± 5% Relative Humidity and a photoperiod of 16:8 (Light: Dark) h. Developmental, survival and fecundity data were analyzed using the age-stage, two-sex life table method. According to the age-stage, two-sex life table, the net reproductive rates (R₀) of ladybird fed on S. avenae reared on Triticum aestivum var. tajan, Hordeum vulgare var. Dasht, Zea mays var. single cross 704 and Sorghum durra var. Speed feed were estimated to be 235.38 ± 36.15, 190.74 ± 33.37, 293.54 ± 46.66 and 137.46 ± 23.66 female offspring / female, respectively. Based on the results, the intrinsic rate of increase as an index of population increase of H. variegata, was 0.181 ± 0.006, 0.179 ± 0.006, 0.163 ± 0.006 and 0.162 ± 0.006 h^-1 preyed on host reared on T. aestivum var. tajan Z. mays var. single cross 704 S. durra var. Speed feed and H. vulgare var. Dasht, respectively. Our findings demonstrate that by using the age-stage, two-sex life table we can accurately describe the growth, survival and development of the predator. Our finding may provide basic information for developing aphid biological control programs.

Background: The concept of allometry states that the relative rate of change of a system unit is a constant fraction of the relative rate of change of the entire system, or of another part of the system.This concept is stated as a nonlinear relationship and has been verified in a variety of natural systems.
Materials and Methods:The allometric relations in various phases of basin evolution in forms of static and dynamic models wasinvestigated.In order to study the dynamic allometry, a model consistingof two basins was developed.The evolution stages and the erosion changes caused by artificial rainfall and tectonic movements and also in static form (natural basins) were monitored.
Results: The existence of allometricrelations in drainage basins that are progressing toward the equilibrium (natural basins and basins affected by erosion) are significant and verifiable.This kind of relations do not exist in tectonic affected basins that were moving away from the equilibrium.
Conclusions:Allometric relations in drainage basins can define different states of system such as equilibrium. Moreover, any factor that causes the basin to move away from equilibrium needs to have an initial effect on basin relations to cause disorder in the system,and this change,in many cases,can be formulated or demonstrated by allometric model. Therefore the allometric equations could be considered an important tool in predicting the evolution of drainage basins and assessing their performance in the past and present.
