There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

An artery, vein, aneurysm, vascular malformation or arterial fistula is occluded through endovascular occlusion by the endovascular insertion of a platinum wire and/or tip into the vascular cavity. The vascular cavity is packed with the tip to obstruct blood flow or access of blood in the cavity such that the blood clots in the cavity and an occlusion if formed. The tip may be elongate and flexible so that it packs the cavity by being folded upon itself a multiple number of times, or may pack the cavity by virtue of a filamentary or fuzzy structure of the tip. The tip is then separated from the wire mechanically or by electrolytic separation of the tip from the wire. The wire and the microcatheter are thereafter removed leaving the tip embedded in the thrombus formed within the vascular cavity. Movement of wire in the microcatheter is more easily tracked by providing a radioopaque proximal marker on the microcatheter and a corresponding indicator marker on the wire. Electrothrombosis is facilitate by placing the ground electrode on the distal end of the microcatheter and flowing current between the microcatheter electrode and the tip.

Inulin and oligofructose belong to a class of carbohydrates known as fructans. The main sources of inulin and oligofructose that are used in the food industry are chicory and Jerusalem artichoke. Inulin and oligofructose are considered as functional food ingredients since they affect physiological and biochemical processes in rats and human beings, resulting in better health and reduction in the risk of many diseases. Experimental studies have shown their use as bifidogenic agents, stimulating the immune system of the body, decreasing the levels of pathogenic bacteria in the intestine, relieving constipation, decreasing the risk of osteoporosis by increasing mineral absorption, especially of calcium, reducing the risk of atherosclerosis by lowering the synthesis of triglycerides and fatty acids in the liver and decreasing their level in serum. These fructans modulate the hormonal level of insulin and glucagon, thereby regulating carbohydrate and lipid metabolism by lowering the blood glucose levels; they are also effective in lowering the blood urea and uric acid levels, thereby maintaining the nitrogen balance. Inulin and oligofructose also reduce the incidence of colon cancer. The biochemical basis of these beneficial effects of inulin and oligofructose have been discussed. Oligofructoses are non-cariogenic as they are not used byStreptococcus mutans to form acids and insoluble glucans that are the main culprits in dental caries. Because of the large number of health promoting functions of inulin and oligofructose, these have wide applications in various types of foods like confectionery, fruit preparations, milk desserts, yogurt and fresh cheese, baked goods, chocolate, ice cream and sauces. Inulin can also be used for the preparation of fructose syrups.

Applications of inulin and oligofructose in health and nutrition.

The herb Artemisia annua has been used for many centuries in Chinese traditional medicine as a treatment for fever and malaria. In 1971, Chinese chemists isolated from the leafy portions of the plant the substance responsible for its reputed medicinal action. This compound, called qinghaosu (QHS, artemisinin), is a sesquiterpene lactone that bears a peroxide grouping and, unlike most other antimalarials, lacks a nitrogen-containing heterocyclic ring system. The compound has been used successfully in several thousand malaria patients in China, including those with both chloroquine-sensitive and chloroquine-resistant strains of Plasmodium falciparum. Derivatives of QHS, such as dihydroqinghaosu, artemether, and the water-soluble sodium artesunate, appear to be more potent than QHS itself. Sodium artesunate acts rapidly in restoring to consciousness comatose patients with cerebral malaria. Thus QHS and its derivatives offer promise as a totally new class of antimalarials.

Intussusception was diagnosed in 20 crossbred cattle. The incidence was more in cattle <2 yr age. Maximum number of cases were recorded in peak summer. Colicky signs preceded other symptoms of obstruction. Sausage like mass could be palpated per rectally just below and to the right of pelvic brim in 13 cases, out of which 5 animals were at advanced pregnancy. Intussusception was noticed more in jejunum and ileum. Intestinal resection and end to end anastomosis was done through right flank laparotomy. Postoperatively, cattle were treated with broad spectrum antibiotic, analgesic, fluid therapy and rumenotoric. Cattle passed dung on the same day in 12 cases, next day in 5 cases and on third day in 3 cases.

A metal/semiconductor system (a-Si/Mn/a-Si) was deposited on the silicon substrate using the electron beam evaporation method. These samples were irradiated using 80 MeV Ni and 100 MeV Ag ions at different fluences ranging from 1×1013 to 1×1014 ions/cm2 for the investigation of mixing threshold. Pristine and irradiated samples have been characterized using Rutherford backscattering spectroscopy (RBS) for depth profile analysis and atomic force microscopy (AFM) for surface roughness study. RBS spectra revels that there is a mixing at 100 MeV Ag ion irradiations which increases with fluence, whereas there is no mixing observed at 80 Ni MeV ion irradiations. We have also tried to investigate the mixing threshold value in this system. The surface roughness, as investigated from AFM, has not significantly changed upon irradiation indicating no contribution of roughness in interface mixing.

The present investigation was carried out using first lactation 16,184 monthly test-day milk yields (MTDMYs) records of 1,583 Karan Fries cattle that calved from 1983 to 2012 sired by 130 bulls maintained at ICAR-National Dairy Research Institute, Karnal. Mixed model analysis was carried out by least-squares maximum likelihood programme to study the effects of genetic and non-genetic factors on first lactation 305-day milk yield (FL305DMY) and MTDMYs record of Karan Fries cattle. The highest and lowest MTDMYs were observed in TD-2 (12.95 kg) and TD-10 (9.72 kg), respectively. The average FL305DMY was 3123 kg. The effect of season of calving was found to be highly significant on all the MTDMYs while non-significant effect was observed on FL305DMY. Period of calving had non-significant effect on most of the MTDMYs and on FL305DMY, whereas; the effect of age at first calving was highly significant on majority of the MTDMYs and on FL305DMY. The heritability estimates for FL305DMY was 0.35±0.07 and for MTDMYs it ranged from 0.11 (TD-11) to 0.34 (TD-6). The genetic and phenotypic correlations among MTDMYs and with FL305DMY were found to be highly significant. The estimates of phenotypic and genetic correlations among all the MTDMYs ranged from 0.15 (TD-1 and TD-11) to 0.83 (TD-8 and TD-9) and 0.29 (TD-1 and TD-10) to 0.99 (TD-2 and TD-3), respectively. High phenotypic and genetic correlations of TD-3 (0.69 and 0.91) and TD–4 (0.65 and 0.99) with FL305DMY indicated that these key test-day yields could be used for the early and accurate selection of animals resulting in faster genetic gain.
