Exposure of P. pdyrphczlum to a subthreshold challenge of Cd’+, which did not delay mitosis. elicited a protective response against a mitotic delay resulting from subsequent exposure to a suprathreshold challenge of Cd2+. Some characteristics of this protective response are herein identified. The concentration of Cd2+ in the subthreshold challenge could be lowered to lo-” M and maintain complet...

The following is the transcript of one of the best press conferences I've ever heard or read about. My preconceived notions about what such a gathering would be like were very strong as I entered the gorgeous Eversbn Museum in Syracuse. I was taken aback by not only the opulence with which food and cocktails were served, but the scene of the reception before the actual conference. It struck me ...

111 25 per cent, of cases may be due to excess of Proteins in the food. Not only this?irregularity in the time and duration of the feeds and sometimes uncleanly habits of the mother, also act as contributory factors. But in niy opinion, based on some recent investigations 011 youngrabbits there is another paramount factor in the etiology of the disease: this is deficiency of the growthproducing...

on this volume, which contained many beautiful drawings and original scientific contributions. The actual inception of the Journal has been recorded by Mr. L. M. Griffiths, for seventeen years Assistant Editor.1 After referring to the preceding Transactions, he continued : " Another four years passed (i.e. 1882) and some members of the Committee thought the time had arrived for the publication ...

Korean food wastes have high moisture content (more than 85 wt%) and their major treatment processes such as drying or biological fermentations generate concentrated organic wastewater (CODs of about 100,000 mgO2/L). For obtaining both wastewater treatment and hydrogen production from renewable resources, supercritical water gasification (SCWG) of the organic wastewater was carried out in this ...

A (NixFeyO4–Ni1?x?Fex’O)/(Cux?’Niy’’) cermet candidate as inert anode was investigated in cryolite at 960 °C. Immersion tests were performed and different conditions tested: ratio, alumina content, electrolyte quality, metallic aluminium content atmosphere. Then, electrolysis realised 0.8 cm-2 for 4 h industrial conditions: grade electrolyte, CR 2.2, saturated Al2O3, °C presence of Al. The init...

UiO-66 là họ vật liệu khung hữu cơ kim loại tổng hợp bằng phương pháp nhiệt dung môi có diện tích bề mặt riêng lớn (1071 m2·g–1). Vật này được biến tính NiCl2 theo trực tiếp (Nix(tt)/UiO-66) và gián (Niy(gt)/UiO-66). Kết quả đặc trưng hai nhiễu xạ tia X, hiển vi điện tử quét phổ hồng ngoại khác nhau không đáng kể. Tuy nhiên, phân trọng lượng đẳng hấp phụ – khử N2 cho thấy sự giữa các hợp.

It has been demonstrated for the first time that severe plastic deformation (SPD) permits to produce metallic alloys containing two coexisting amorphous phases from crystalline multiphase alloy. The as-cast Ni60Nb18Y22 alloy was coarse-grained and contained mainly NiY phase (grain size 25 µm) also NbNi3 ,N i2Y, Ni7Y2 Ni3Y 3–5 µm). High pressure torsion (4 GPa, 10 torsions) completely changed st...
