Some patients with hypothyroidism still remain symptom after prolonged treatment with thyroxine. Alternative treatment needs to be explored. The treatment is described as overlapof acupunture, supplemented with electric acupuncture, magnetic acupuncture, ear acupuncture, herbaltreatment, and acupressure of thyroid.

A series of Ni0.6-x/2Zn0.4-x/2SnxFe2O4(x = 0.0, 0.05, 0.1, 0.15, 0.2, and 0.3)(NZSFO) ferrite composities have been synthesized from nano powders using a standard solid state reaction technique. The spinel cubic structure of the investigated samples has been confirmed by x-ray diffraction(XRD). The magnetic properties such as saturation magnetization(Ms),remanent magnetization(Mr), coercive field(Hc), and Bohr magneton(μ) are calculated from the hysteresis loops. The value of Msis found to decrease with increasing Sn content in the samples. This change is successfully explained by the variation of A-B interaction strength due to Sn substitution in different sites. The compositional stability and quality of the prepared ferrite composites have also been endorsed by the fairly constant initial permeability(μ’) over a wide range of frequency. The decreasing trend of μ’ with increasing Sn content has been observed. Curie temperature TChas been found to increase with the increase in Sn content. A wide spread frequency utility zone indicates that the NZSFO can be considered as a good candidate for use in broadband pulse transformers and wide band read-write heads for video recording. The composition of x = 0.05 shows unusual results and the possible reason is also mentioned with the established formalism.

Significant uncertainties remain regarding the temporal evolution of natural vegetation during the Quaternary, and drivers of past vegetation change, on the Chinese Loess Plateau （CLP）. This study presents analyses of total organic carbon isotopic composition （TOC） and n-alkane ratios （C31/C27） from the Lingtai loess-palaeosol sequence on the central CLP over the last 450 kyr. The results demonstrate that the vegetation in this region comprised a mix of C3 and C4 plants of herb and woody growth-form. C3 plants dominated for most of the last 450 kyr, but this did not lead to extensive forest. C3 woody plants were more abundant in mis9 （S3 period） and mis5 （S 1 period） during warm and humid climate conditions. Herbs increased in the region since 130 kyr, possibly as a result of increased aridity. On the orbital timescales, there was a reduction of C3 herbal plants in mis 11 （$4） than in M1S 12 （L5）, and in Holocene than in the last glacial period. Our isotope and n-alkane proxy records are in agreement with Artemisia pollen changes in the region, which is/was the dominant species in this area and varying due to different heat and water conditions between glacial and interglacial periods. Though the climate in mis1 （SO） was similar to that in mis11 （S4）, a significant increase in woody plants during the Holocene suggests the impact of human activities and ecological effects of changes in fire activity.

introduction: The study of mortality is an indicator that allows a control and a review of the therapeutic measures in the hospital environment. The purpose of this work was to determine the epidemiological profile of the patients who died and analyse the circumstances of the death in a hospital service. Material and Methods: it is a retrospective descriptive study conducted in the service of Stomatology, maxillofacial and plastic surgery of the face over a period of 10 years (from January 1999 to December 2008). Seventy-two cases have been taken into account. Results: The crude death rate was 4.29%. Higher level of male has been noted with a sex ratio of 1.77. The most affected age groups were the 3rd and 2nd decades, respectively with 20.8% and 19.4% with an average age of 39 years. Cellulitis of the face and their complications were responsible for deaths in 58.33% of cases. The majority of deaths occurred between 6 p.m. and 6 a.m. (65.28%). These deaths were preventable in 5.6% of cases. Conclusion: Facing the lack of description of the ultimate circumstances of death in the medical records, the conclusion of this study has been the establishment of a regular medical audit in the service, which would track mortality in order to reduce its rate.
