Single leaf

Typical uses Smaller scale batch processing where good solids washing is required. 

Typical particle size and feed concentration range 1-500 pm and 1-10% w/w (Nutsche) 20-80,000 pm and 5-30+% w/w (tipping pan). 

Filter type Effective max. submergence (% of cycle) Total under active vacuum (% of cycle) Max. for washing (% of cycle) Max. for deliquoring only (o/o of cycle) Required for cake discharge (o/o of cycle) 

Horizontal belt As required As required As required As required 0 

Smaller Nutsche filters require a manual cake discharge while larger machines generally employ mechanical ploughs or rakes. Fully automated versions of the vacuum Nutsche filter are available and some include cake smoothing devices to minimise the problems of cake cracking. A range of filter media can be accommodated with filter areas up to a maximum of 10 m.

Turgor pressure of single leaf cells was measured by an improved version of the cell pressure probe according to Husken et al. (7). Mikrocapillaries were pulled on a laser heated pulling device. 

Once the immunoassay that meets the study objectives has been identified, sample collection begins. Proper sampling is critical in order to obtain meaningful results from any type of analytical assay. An appropriate sampling scheme will support the objective of the test. For example, a plant breeder may take a single leaf punch to determine quickly whether a specific protein has been expressed in an experimental plant. A more complex sampling regime would be used to determine the expression...

A severe mechanical wound on a single leaf of tomato plants initiates a complex series of extracellular and intracellular reactions which result in the synthesis and accumulation of two proteinase Inhibitors, Inhibitors I and II, in leaf cells (J, 2. A second wounding, within a few hours, results in a 2-3 fold Increase in the rates of accumulation initiated by the... 

I have been growing two salvia plants for a few weeks now. [Props out to my righteous benefactor, who will remain nameless for reasons of National Security.] I could have tried some leaves before this, but I felt that I needed to earn the experience by cultivating and caring for the plant myself. Last week I tried a single leaf, to introduce myself. It was just a threshold dose, but I sensed the power that lay in these leaves. This time I had primed the pump with another, less exotic green ally before raising the bowl of salvia to my lips.

In what many consider to be a landmark publication on metabolomics, Fiehn et al. (2000) state it is crucial to perform unbiased (metabolite) analyses in order to define precisely the biochemical function of plant metabolism. The authors argue that for metabolomics/metabolite profiling to become a robust and sensitive method suited to automation, a mature technology such as gas chromatography-mass spectrometry (GC-MS) is required as an analytical technique. The authors go on to describe a simple sample preparation and analysis regime that allowed for the detection and quantification of more than 300 compounds from a single-leaf sample extract. 

Laurel is another evergreen that can cause death by the eating of a single leaf. It is best percolated and disdlled but it can be used as it is and put in stews and as a garnish on hors d oeuvres. 

Sanguinaria is one of the earliest spring flowers. It has a lovely white flower and produces only a single leaf and a flowering scape about 6" high. When the leaf first appears it is wrapped round the flower bud and is a grayish-green color cov-... 

Constabel et al. (595) analyzed 76 cell clones derived from one leaf of a C. roseus plant. Although this work shows the variation in alkaloid spectra of cell lines derived from a single leaf, the variation was low when compared to that found previously with serially subcultured callus and cell suspensions derived from different plants. The majority of clones showed the occurrence of Corynanthe, Strychnos, and Aspidosperma alkaloids. Of the 76 clones analyzed, 41 produced ajmalicine.
