When we speak of forest products we include not only the timber from the trees, but also such other products as derive from the bark, the leaves, or the roots. In this address, however, I shall be dealing almost exclusively with timber and its derived products. By a long-standing gentlemen’s agreement the other products, as well as certain aspects of pulping, are dealt with by the Colonial Products Advisory Bureau at South Kensington, and although (or perhaps because) the boundary between us is not closely defined, it has proved over the years a very satisfactory arrangement. The work of the Forest Products Research Laboratory is, then, mainly research on wood. The forester grows or tends the tree until it is felled. From that point it is the business of the Forest Products Research Laboratory. Before I deal with the actual research work, however, I should give you some idea of the setting in which it is carried on. The Laboratory is situated in the Chilterns, about 20 miles east of Oxford. It has about 36 acres of ground, of which 3 acres are laboratory floor-space. The scientific staff number roughly 100, and there are in addition the administrative and technical services. It is, therefore, a fairly large organization.

Efficient Extraction

Chromium is an element that possess several oxidation states and can easily pass from one to another, so its behavior in soils is very complex. For this reason, determining its fate in the environment can be difficult. In this research work we tried to determine which factors affect the chromium fractionation in natural soils, conditioning chromium mobility. We paid special attention to the parent material. For this purpose, extraction experiments were carried out on spiked soils incubated for 50–60 days, using H2O, CaCl2 and diethylenetriaminepentaacetic acid (DTPA). The most efficient extraction rate in all soils was achieved using water, followed by CaCl2 and DTPA. We obtained models with an adjusted R2 of 0.8097, 0.8471 and 0.7509 for the H2O Cr, CaCl2 Cr and DTPA Cr respectively. All models were influenced by the amount of chromium added and the parent material: amphibolite and granite influenced the amount of H2O Cr extracted, and schist affected the other two fractions (CaCl2 and DTPA). Soil texture also played an important role in the chromium extraction, as well as the amounts of exchangeable aluminum and magnesium, and the bioavailable phosphorus. We concluded that it is possible to make relatively accurate predictions of the behavior of the different Cr fractions studied, so that optimized remediation strategies for chromium-contaminated soils can be designed on the basis of a physicochemical soil characterization.

Abstract Some farmers mechanically screen farmer stock (FS) peanuts after combining to remove undesired materials for value and quality improvement. Screening is accomplished with low capacity, portable screens at the field after combining or with high capacity cleaners or screens at buying points. An alternative method for FS peanut screening has been developed cooperatively by Amadas Industries and USDA-ARS, National Peanut Research Laboratory utilizing an experimental combine screening attachment. The attachment is a hydraulically driven, rotating cylindrical screen (trommel) with an axis inclined less than 10° from horizontal during operation. Peanuts are screened with the trommel prior to entering the combine basket, and smaller, unwanted materials are returned to the soil. Thirty-eight lots of FS peanuts averaging 3.27 t/lot were combined throughout all U.S. peanut-producing regions to examine performance. Foreign materials for the screened lots averaged 2.15% less than the unscreened lots (P = 0.05). Hulls were 0.62% less in the screened lots (P = 0.05). None of the other grade factors or market values per hectare were significantly different for runner peanuts. Foreign materials for screened virginia peanuts were 2.44% less than in unscreened (P = 0.01). Loose shelled kernels were 0.44% higher (P = 0.05), hulls 0.67% lower (P = 0.10), and damage 0.56% higher in screened peanuts than in unscreened. None of the other grade factors or market values per hectare were significantly different for Virginia peanuts. Although most grade factors and values per hectare were not significantly different for screened and unscreened peanuts tested, foreign materials were reduced significantly providing needed quality improvement. Possible cleaning costs also could be reduced with the attachment.

My apologies to Mr. Chrétien and to your readers for “developing some simplistic formulas on Burundi” in my quest for “media success.” No such simplistic formulas enter his criticism of my Congressional testimony. On the one hand, I am taken to task for not conceding that my interpretation of the Hutu-Tutsi conflict as a recent phenomenon is the product of Chrétien’s “patient research work” over the last quarter of a century; on the other hand, “some very similar analysis” had appeared in my “excellent work of 1970,” which came out long before Mr. Chrétien embarked on his patient research! Try to figure that one out if you can.

Objective: The aim of this study was to investigate, for the first time, the possible in vivo genotoxic and carcinogenic activity associated with exposure to norgestrel (NGT) drug through employing the very recently established and adjusted genotoxic and tumorigenic methods in Drosophila melanogaster.Methods: Two in vivo genotoxic test systems were used; one detects the somatic mutation and recombination effects (somatic mutation and recombination test [SMART] wing-spot test) and the other detects the primary DNA damage (the comet test) in the body cells of D. melanogaster. On the other hand, the warts (wts)-based SMART assay is a vital genetic examination in Drosophila used to identify and characterize cancer potential of compounds.Results: Four experimental doses of NGT were used (ranging from 0.24 μM to 16 μM). NGT was found to be non-genotoxic at all tested concentrations even at the highest dose level 16 μM and failed to increase the frequency of tumors in the somatic cells of D. melanogaster.Conclusion: Our results strengthen the hypothesis that steroidal drugs might act through a non-genotoxic carcinogen mechanism where the carcinogenic properties occur by direct stimulation of cellular proliferation through a steroid receptor-mediated mechanism. In addition, the results obtained in this research work may contribute to highlighting the importance of NGT as a potent neuroprotective antioxidant drug.

The research work concerns the development in the Italian literature of the French theme of Neuf Preux, and Particularly Took into account a crown of sonnets of nine famous men linked to an alleged cycle of paintings attributed to Giotto's in the palace of Castel Nuovo in Naples. The survey highlighted how in medieval Italian literature, beyond the more or less explicit recovery of the French literary tradition, occupies a prominent place the function that these poems take in the view of the literature of the time. The survey actually shows the two faces of the series of famous heroes, which on one hand is the mouthpiece of the political ideals and civil inspired by the courteous and Roman antiquities, on the other hand appears to be ripe fruit of a didactic poem in which the adherence to the motto of "ut pictura poesis" become as a kind of surface projection of images.

Here we have juxtaposed two distant cosmic locations of the Sun and AGN where neutral hydrogen appears in a close connection with hot coronas. Besides the solar photosphere, chromosphere and prominences where the presence of neutral hydrogen is well established, its emission quite high in hot solar corona is still puzzling. Some of earlier observations where H? emission in solar corona was detected in eclipse and in daily coronagraphic observations are reviewed. A proper theoretical explanation of this cold chromospheric-type emission in the hot corona does not exist yet. On the other side, a similar emission of hydrogen lines is present in Active Galactic Nuclei (AGNs). Much research work is currently being done in this field. We outline some of the concepts of the AGN structure prevailing in the astrophysics today.

Nadi Pariksha is the most effective diagnostic tool known in the medical field. It is cost effective,  accurate,  safe,  and gives quick results. We can conduct Nadi Pariksha on healthy individuals as well as all patients irrespective of stage of the disease also,  and even pregnant woman,  children,  elderly can undergo without any harm or side effects. However,  this technique is not being widely practised at present,  because of lack of training,  practise and knowledge about it in the present day among Ayurveda vaidyas. An iconic factor for identification of a physician,  irrespective of the time,  Region,  Nadi Pariksha can be highlighted as a common factor or even System of Medicine or Civilization of the known world. Thus,  we can perceive that Nadi Pariksha or the pulse examination remains as an effective diagnostic tool since ages. Nadi Pariksha was not been discussed among the Brihatrayees of Ayurveda. Acharya Sharangdhara was the first to document in the doctrines of Ayurveda. Thus Acharya Sharangdhara is considered as ‘The Founder of Nadi Pariksha’in Ayurveda. Nadi Pariksha was titled under the Pancha-Nidana by Acharya Sharangdhara and Ashta Sthana Pariksha by Acharya Yogaratnakara. It was the Foremost among all the other diagnostic tools mentioned by him. Later Acharyas like Acharya Bhava Mishra,  Acharya Yogaratnakara,  Acharya Basavaraja,  Acharya Kanada Maharishi,  and Acharya Ravana have contributed in giving more descriptions and importance. In the recent days Dr. Vasant lad and Dr. Sarvadeva Upadhaya’s research work interest and scope of Nadi Pariksha.

A total of 1,020 serum and plasma specimens were tested using the Venereal Disease Research Laboratory (VDRL), Rapid Plasma Reagin (RPR) card, Reagin Screen (RST) and Fluorescent Treponemal Antibody-Absorption (FTA-ABS) tests. In 257 normal patients, all screening tests were nonreactive; the FTA-ABS test was reactive for one patient. In 588 patients with treated and untreated syphilis, the RST results were 91.7% in agreement with the VDRL and RPR results. In 175 patients with diseases that cause biological false reactions, the RST was 94% in agreement with the other screening tests. The titer of the RST was within one dilution of the corresponding VDRL titer in 91.7% of the 360 speciments tested and within one dilution of the RPR titer in 96.9% of 358 specimens quantitated by both tests.
