Staining Wood and Natural Materials Using PRO Washfast Water Based
Staining Wood and Natural Materials using PRO WashFast Water-Based Dyes Please read directions carefully before starting. Many materials, whose surface is only slightly wettable, may be colored with water-based (water soluble) dyes resulting in colored surfaces that do not hide the grain of the wood or the character of the substrate. This process is also suitable for the coloration of feathers, retouching wool tapestries and wool or nylon carpeting. Basically anything that does not have the high wash fastness requirements of wearable clothing fabrics. Wet fastness is good. Always do test samples before working on a large project. For additional information visit our web site at www.prochemicalanddye.com. Wear rubber gloves, apron, or old clothes. Utensils used for dyeing should never be used for food preparation. Procedure: 1. Dissolve the PRO WashFast Acid dye by placing 1 tsp (2.5 gm) of the dye in a one cup (250 ml) Pyrex container. Add 1 or 2 tsp (5 or 10 ml) of boiling water to make a paste. Gradually add more boiling water with continuous stirring to the 2 cup (125 ml) mark. Set aside to cool. 2. When cooled to room temperature, fill to one cup (250 ml) mark with denatured grain alcohol or Isopropyl rubbing alcohol (90%). Store in re-sealable glass container. 3. Apply to surface of substrate with foam brush or immerse object into dye solution for several minutes. Air dry and repeat procedure as often as needed for deeper color allowing previous coat to dry thoroughly. 4. After thorough drying, wood and similar materials may be coated to seal in the color and give lasting protection to the wood itself. -

(030) EXPLANATION Diphenylamine Was Originally Evaluated in 1969
155 DIPHENYLAMINE (030) EXPLANATION Diphenylamine was originally evaluated in 1969 and subsequently in 1976, 1979, 1984 and 1998. It was identified for re-evaluation within the CCPR Periodic Review Programme at the 1996 CCPR (ALINORM 97/24), proposed for consideration by the 2000 JMPR at the 1997 CCPR (ALINORM 97/ 24A) and the evaluation deferred until 2001. An ADI of 0-0.08 mg/kg bw was established by the 1998 JMPR replacing the previous ADI of 0-0.02 mg/kg bw. Because of toxicological concerns, attention was given to the various method of synthesising and purifying diphenylamine to produce a quality acceptable for the treatment of apples and pears. It was proposed that a specification for a pure (food grade) diphenylamine should be drawn up. The manufacturer reported new studies of physical and chemical properties, animal, plant and soil degradation, analytical methods, storage stability, farm animal feeding, supervised residue trials and food processing. The governments of Australia and The Netherlands have reported information on national GAP and/or residue data.

Pacific Northwest Forest and Range Experiment Station, Portland, Oregon. Twelve different nitrogen (N) fertilizer treatments were tested on potted western hemlock (Tsuga heterophylla (Raf. ) Sarg.) seedlings. Fertilizers affected soil N and pH, and growth and foliar chemical com position of seedlings. Ura plus N-Serve and sulfur-coated urea appear more promising for promoting growth than other fertilizers tested. Results, however, do not explain reported variability in response of hemlock stands to N fertilization. Keywords: Nitrogen fertilizer response, seedling growth, western hemlock, Tsuga heterophylla.

A Study of Rawitz's 'Inversion Staining' by ALEKSANDRA PRZEL^CKA
231 A Study of Rawitz's 'Inversion Staining' By ALEKSANDRA PRZEL^CKA {From the Cytological Laboratory, Department of Zoology, University Museum, Oxford, and the Nencki Institute, 3 Pasteur St., Warsaw 22; present address, Nencki Institute) SUMMAHY The Rawitz method involves mordanting with tannic acid and potassium antimony tartrate, and staining with basic fuchsine. The mordanting causes basic fuchsine to act as though it were an acid dye ('inversion staining'). A modification of the method is described in the present paper. This modification makes it possible to obtain the same results in a shorter time. The chief substances stained by Rawitz's method are phospholipids, certain pro- teins, and certain polysaccharides. Although the method cannot be regarded as a cytochemical test in the strict sense, yet it gives useful indications of chemical composition and in addition is valuable to the morphological cytologist as a technique for showing certain cytoplasmic inclusions (mitotic spindle, acrosome, mitochondria, 'Golgi apparatus' of certain cells). INTRODUCTION T is well known that the so-called 'Golgi apparatus' is extremely difficult to I reveal by any staining method. Baker, in the course of his investigation on this organelle in the epididymis of the mouse, found that it can be stained by basic fuchsin after a special mordanting process (1957). The method was taken from Rawitz (1895), who found that basic fuchsin, if mordanted with tannic acid and potassium antimony tartrate, loses the character of a dye for chro- matin and colours the cytoplasm instead. Rawitz called this effect 'inversion staining'. Since this technique, when applied to various kinds of cytological material, gave good selectivity in visualizing certain delicate cell structures, it seemed interesting to investigate the nature of the chemical compounds which are responsible for positive Rawitz staining. -

Writes of Spring
On 20 March 2019 we asked people across the UK to capture the arrival of the first official day of spring and help create a crowd-sourced nature diary. More than 400 people did just that from across the four corners of the UK – celebrating this season of colour and the natural world coming to life. The following pages are a selection of the entries curated by the writer Abi Andrews. Introduction n 2018, my spring was spent in a caravan, in a glade in view of Carningli mountain, Itopped by a rocky grey outcrop with purple heathers, confettied below with vivid yellow gorse. The caravan sat within the Pembrokeshire Coast National Park, in an area that saw an influx of ‘back-to-the-landers’ during the seventies. In it you will find covert, sympathetically built dwellings and cooperative human communities in repurposed farmhouses, lying between woods of bent, blackened oaks, their flamboyant colonies of lichens, and boulders covered with soft and ecstatic mosses. On the moors are strange, stunted Welsh horses, their silhouettes hunched like the simplified animals of Neolithic rock art. Clear spring water gurgles up and silvers everything, running brown through the taps after a heavy rain. At night, owls call to each other. In spring 2019, I was the most attentive to the living world that I have ever been, for the transition of a season. I grew up in suburbia, and moved soon after to a city. Living closer to the land has offered me an anchoring, in noticing the seasons more: the fatigue that comes with winter darkness, the processing of firewood for next year, the harvesting of food — being reminded all the time of the future by preparing for it. -
