A metamorphic rock complex consists of slate, phyllite, micaschist and marble with NE – SW shistosity has cropped out in Neybaghi area in the NE of Myaneh.  Impure marbles occur as thick and thin layers or massive bodies within the centeral area of this complex. Textural and mineralogical evidences, revealed two metamorphic stages.  The early stage is testified by the minerals such as pyroxene (diopside), epidote (clinozoisite), amphibole 1 (edenite-pargasite) and plagioclase 1.  The main stage have chlorite (clinochlore), phlogopite, amphibole 2 (tremolite) and plagioclase 2.  P-T-XCO2 have been estimated for the early and main stage of metamorphism by computing nonideal and asymmetrical fugacity and activity and programing in THERMOCALC software for fluid and solid phases.  The estimations give pressure, temperature and XCO2 of 9.5Kbar, 660°C and 0.35, whereas the main stage has been constrained at P=4.2Kbar, T=510°C, XCO2=0.4. The obtained P-T path shows that the Neybaghi marbles were formed under medium pressure condition and overprinted by a low pressure metamorphism.  This type of P-T trend can be formed in collisional tectonic regime.

This study was performed to compare the stiffness of hamstring and rectus femoris muscles in subjects with anterior knee pain and normal subjects. In this non experimental and case-control study، 20 persons with anterior knee pain were selected simply from convenient sample and 20 healthy persons were selected by matching method. proximal and distal stiffness of hamstring and rectus femoris muscles were measured using an isokinetic device in the passive mode. Also، maximal concentric peak torque during flexion and extension movements of hip and knee، in two groups were compared by independent T-test and correlation analysis. There was no significant difference between anterior knee pain and proximal compartment of rectus femoris (P=0. 320) and hamstring (P=0. 125) stiffness، but there was significant difference between anterior knee pain and distal compartment of rectus femoris and hamstring stiffness (P<0. 001). Significant relationship was found between anterior knee pain and muscles strength (P<0. 001). No correlation was found between strength and stiffness of rectus femoris (P=0. 356) and hamstring muscles (P=0. 643) in patients group، but in healthy subjects this relationship was found (P<0. 001). In patients with anterior knee pain، hamstring and rectus femoris muscles stiffness increased and muscle strength decreased. Increasing of muscle strength was effective on stiffness in healthy subjects، but there was no relation between them in patients group. Also rectus femoris and hamstring muscles possibly have different proximal and distal neuromuscular compartments. Key words:

The main purpose of this research was to compare the physical and chemical characteristics of Common compost and Vermicompost (obtained from the same condition and organic matter).The worm species used in this research was Eisenia fetida. This research was carried out in green house for 5 months and it was performed in factorial RCD with 4 replicates. Experimental treatments consisted of 3 combination levels of organic matter as: 1- (A) 60% of cow manure and 40% of plant debris, 2-(B) 50% of cow manure and 50% of plant debris, 3-(C) 40% of cow manure and 60% of plant debris. And second factor was: 1-(W1) & 2-(W0) the treatment with or without any earthworm, respectively (earthworm treatment).The results demonstrated that the earthworm treatment effect on the whole measured characteristics (20 characteristics) except of Zn and EC amount has been significant (P  0.01). The vermicompost treatment which was measured 13 characteristics for it (65% of characteristics), was the first (class a). W1 in 15 measured characteristics (75%) and W0 by 25% characteristics were in the first and second class, respectively.Thus, the treatment of vermicompost consists of 60% cow manure and 40% of plant debris with Eisenia fetida has been known the best kind of compost.
