Schumacher and Halbsguth first demonstrated ectodesmata as pores or channels in the epidermal cell walls in haustoria of Cuscuta odorata L. by light microscopy in tissues fixed in a sublimate fixative (30% ethyl alcohol, 30 ml:glacial acetic acid, 10 ml: 65% nitric acid, 1 ml: 40% formaldehyde, 5 ml: oxalic acid, 2 g: mecuric chloride to saturation 2-3 g). Other workers have published electron micrographs of structures transversing the outer epidermal cell in thin sections of plant leaves that have been interpreted as ectodesmata. Such structures are evident following treatment with Hg++ or Ag+ salts and are only rarely observed by electron microscopy. If ectodesmata exist without such treatment, and are not artefacts, they would afford natural pathways of entry for applied foliar solutions and plant viruses.

Migraineurs with and without aura (MWAs and MWOAs) as well as controls were measured twice with an interval of 7 days. The first session of recordings and tests for migraineurs was held about 7 hours after a migraine attack. We hypothesized that electrophysiological changes in the posterior cerebral cortex related to visual spatial attention are influenced by the level of arousal in migraineurs with aura, and that this varies over the course of time. ERPs related to the active visual attention task manifested significant differences between controls and both types of migraine sufferers for the N200, suggesting a common pathophysiological mechanism for migraineurs. Furthermore, migraineurs without aura (MWOAs) showed a significant enhancement for the N200 at the second session, indicating the relevance of time of measurement within migraine studies. Finally, migraineurs with aura (MWAs) showed significantly enhanced P240 and P300 components at central and parietal cortical sites compared to MWOAs and controls, which seemed to be maintained over both sessions and could be indicative of increased noradrenergic activity in MWAs.

Pilot data indicate that wood chip pretreatment with oxalic acid reduced the specific energy required to make thermomechanical pulp. A combined oxalic acid/bisulfite treatment resulted in 21% refiner energy savings and 13% increase in brightness for aspen. A low level of oxalic acid treatment was effective for spruce. Energy savings of 30% was observed with no significant change in strength properties. Adding bisulfite did not significantly increase the brightness of the spruce pulp. For pine, the optimum treatment was a moderate level of oxalic acid, which resulted in 34% energy savings and an increase in strength properties. For all of these treatments 1–3 w/w % carbohydrates were recovered, which can be fermented to produce ethanol. The extract sugar solution contained significant quantities of arabinose.

During this recent two decades, national economy sharia continiue growth.Though it just still smaller compare to the existing of conventional finance, itconscioused the growth of sharia finance currently has a significant enhancement. Thepositive and stable economy performance has given good opportunities to thedevelopment of sharia economy in Indonesia. The existence of syariah economy inIndonesia, who has a muslim mayority, is a new point of national economy history.Sharia banking is one of the tools for developing national economy sharia. Manyproducts offered by national sharia banking, which includes basic principles ofimplementation with profit sharing. One of them is Bai’ Bithaman Ajil, which is the partof trading (Baiah). Bai’ Bithaman Ajil product is expected as an alternative for society tochoose sharia banking as a mediator in transaction, specially to fulfill production needsas well as consumption needs, whose transactions are done on a long-term credit.

The development by ruminants of strong conditioned flavour aversions (CFAs) to foods associated with the administration of LiCl (an artificial toxin) has demonstrated their potential to avoid feeds that cause negative postingestive consequences (Provenza, 1995). Weaker CFAs are formed when they ingest foods with the detrimental secondary plant compound, oxalic acid (Kyriazakis et al. 1997). Moreover, animals may exhibit conditioned preferences (CFPs) for foods supplying appropriate amounts of nutrients such as nitrogen (Provenza, 1995). In this study we tested whether a continuum exists in the formation of CFAs and CFPs to foods that are associated with increasing availability of sulphur (S) in crossbred ewes.
