  1. Germ pore

    A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be wikt apical apical or eccentric in its location, and, on light microscopy , may be visualized as a lighter coloured area on the cell wall. Apical germ pore is a term applied to mushroom spores which have a pore at one end. Some spores have a hole in the cell wall where the first strand of germinating mycelium emerges. If the cell wall is divided from one end to the other, this is called a germ slit . Commonly the germ pore is at one end of the mushroom spore and is called an apical pore . Mushroom genera with apical germ pores include Agrocybe , Panaeolus , Psilocybe , and Pholiota .

    Pore water pressure refers to the pressure of groundwater held within a soil or Rock geology rock , in gaps between particles pores . Pore water pressures in below the phreatic level see also groundwater are measured in piezometer s. The vertical pore water pressure distribution in aquifer s can generally be assumed to be close to Hydrostatic pressure hydrostatic . In the unsaturated zone the pore pressure is determined by capillary action capillarity and is also referred to as tension , suction or matric pressure. Pore water pressures under unsaturated conditions vadose zone are measured in with tensiometers. Tensiometers operate by allowing the pore water to come into equlibrium with a reference pressure indicator through a permeable ceramic cup placed in contact with the soil Pore water pressure sometimes abbreviated to pwp is vital in calculating the stress state in the ground soil mechanics , from Karl von Terzaghi Terzaghi s expression for the effective stress of a soil . ISO 11276 1995 BS 7755 5.1 1996 Soil quality Determination of pore water pressure Tensiometer method , which is identical with ISO 11276 1995, defines pore water pressure as the sum of matric and pneumatic pressures Matric pressure The amount of work that must be done in order to transport reversibly and isothermally an infinitesimal quantity of water, identical in composition to the soil water, from a pool at the elevation and the external gas pressure of the point under consideration, to the soil water at the point under consideration, divided by the volume of water transported. ref name BS 7755 1996 Part 5.1 BS 7755 1996 Part 5.1 ref Pneumatic pressure The amount of work that must be done in order to transport reversibly and isothermally an infinitesimal quantity of water, identical in composition to the soil water, from a pool at atmospheric pressure and at the elevation of the point under consideration, to a similar pool at an external gas pressure of the point under consideration, divided ...   more details

    wikify date February 2011 Orphan date January 2011 unreferenced date February 2010 Pore pressure gradient is a dimensional Petrophysics petrophysical term used by drilling engineer s during the design of drilling programs for drilling constructing Oil well oil and gas wells into the earth. It is the pressure gradient inside the pore space of the rock column from the surface of the ground down to total depth TD , as compared to the pressure gradient of seawater in deep water. Whereas in pure math , the gradient of a scalar function expressed by the math notation grad f may not have physical units associated with it in drilling engineering the pore pressure gradient is usually expressed in API type International Association of Drilling Contractors IADC physical units of measurement, namely psi per foot. In the well known formula P 0.052 mud weight total vertical depth taught in almost all petroleum engineering courses worldwide, the mud weight MW is expressed in pounds per U.S. gallon, and the total vertical depth TVD is expressed in feet, and 0.052 is a conversion constant that can be derived by dimensional analysis later.

It was released in the 1995 Kolkata Book Fair . It was not an original Moheen album, like earlier releases. It was released nearly twenty years after the last album by the group had been released. Many of the songs were not composed by Moheen, and none of them were sung by Moheen. Moheener Ghoraguli only acted as an umbrella to bring disparate bands and individuals together and provided a platform to these upcoming talents of the Bengali music scene to perform. Most of the members of the band had already moved ahead with their careers and lives, and so the only people directly involved in the making of this, and the next three albums, were Gautam Chatterjee Gautam Chattopadhyay , Abraham Mazumdar, Tapas Das and Pradip Chattopadhayay.

In this scene, Curly McLain, is visiting the threatening farmhand Jud Fry, who lives in an outbuilding that was once a smokehouse. He subtly insults Jud throughout, however Jud doesn t pick up on this. The most notable portion is when he imitates the speech and candor of a chanting preacher, expressing to Jud that even though he was misunderstood and called mean names it was really just a shame because Jud never showed anyone how much he cared. In a plot to try to get rid of Jud, Curly suggests how the community would honor Jud, should he commit suicide , and how his corpse would look clean and respectable while on display until they run out of ice . blockquote He looks like he s asleep, It s a shame that he won t keep But it s summer and we re running out of ice. blockquote Category Songs from Oklahoma Category 1943 songs Category Songs with music by Richard Rodgers Category Songs with lyrics by Oscar Hammerstein II Show tune stub ...   more details
