The strong electro mechanical coupling exhibited by the ferroelectric materials is the remarkable feature of these materials. Therefore, they find applications in sensors, actuators for producing ultrasonics and micro positioning. The material dichloridoglycine zinc dihydrate is a centrosymmetric ferroelectric crystal. In the present study, this crystal has been grown from a mixture of glycine and zinc chloride. The dielectric constant and the dielectric loss of the grown crystal were studied as a function of frequency and temperature, and the corresponding relaxation time (τ), relaxation frequency (Fr) and the activation energy have been calculated. The ferroelectric property of the crystal has been confirmed by dielectric studies. The ferroelectric characteristics of the crystal have been studied and reported.

Advances in Breast Cancer Research 2014年第3期3卷 88-95页

We report usefulness of ultrasound used as an adjunct diagnostic tool to mammogram in routine annual checkup for women breasts of certain ages and breast mass. The purpose of breast imaging is to detect areas of tissue distortion and breast cancers. A mammogram is the common diagnostic imaging modality used to find breast diseases but sometimes the mammogram might not give the doctor enough information especially in women with dense breasts. As a result, the patient may be asked to undergo ultrasound or magnetic resonance imaging as a better mean of judgment to the case. Because ultrasound is widely used, simple and safe to patients we were encouraged to emphasis on exploring its role adjunct to mammogram. A retrospective observation study was done at the diagnostic radiology department at King Abdulaziz University Hospital (KAUH) in the period from January 2012 to June 2012;we covered all women with dense breasts in mammography and ultrasound units. The study group was 40 patients. All patients were imaged with both mammography and ultrasound. The statistical measures of accuracy, sensitivity and specificity were calculated using the SPSS program. The results we obtained suggest that age and the physical density of breast potentially affect mammogram images of women with 41 years or smaller with sensitivity 66% and specificity 68%. Therefore, we recommend using ultrasound alongside the mammogram?in women with dense breast for better diagnosis of small cancers that were not identified on mammography or clinical breast examination alone.

针对以往氯衰减模型的局限性,提出一种旨在提高预测结果准确性和实用性的新的氯衰减模型——速率系数可变模型(Variable Rate Coefficient,VRC),模型的建立基于双分子二级反应动力学速率方程,共包含4个参数(X0,κ0,kmin和α).采用6个水源的实验数据对VRC模型、一级模型以及由Boccelli等人建立的二级模型进行校核和比较分析.结果表明:VRC模型对所有数据集的拟合情况均明显优于另外两个模型,可以更为准确地预测氯的衰减情况.为保证模型预测结果的精度,在校核VRC模型时,除了最好使用至少1组初始氯质量浓度较高的数据集以保证模型的稳定性之外,还应调整输入VRC模型中的初始氯质量浓度以减小模型预测值和实测值之间的差距.

Introduction: Ectopic pregnancy is dreadful and can lead to the death of the patient if it is ignored. diagnosed early, it offers the possibility of medical treatment with methotrexate. Objective: To describe the prognosis of ectopic pregnancies treated methotrexate. Patients and methods: Retrospective study of the management of ectopic pregnancy by methotrexate at Senlis hospital from June 2020 to may 2021 were included in the study, patients with a Fernandez score of less than 13, and having received methotrexate as first-line treatment. data were collected using gynecological emergency admission registers, and telephone interviews. Results: 35 cases were identified. The average age of the patients was 32 years old. Forty-nine percent were smokers. The mean gestational age was 5 weeks + 2 days. The diagnosis was made in all of our patients with the combination of the kinetics of ß-hcg and vaginal ultrasound. The size of adnexal mass was less than 4 cm with an average size of 20 mm. The average value of ß-hcg was 1405 IU/L. All patients had received a single dose of methotrexate 1 mg/kg intramuscularly. A second dose was administered to 17.1% of patients for stagnation or re-ascension of the ß-hcg level. The success rate was 91.4%. Thirty percent were obtained spontaneous intra uterine pregnancy, the first year following methotrexate treatment. Conclusion: The success rate of medical treatment for ectopic pregnancy is high in terms of meeting the eligibility criteria for treatment. The subsequent prognosis of fertility is generally preserved.

We have successfully grown an arsenopyrite marcasite type RhSb2 single crystal, and systematically investigated its crystal structure, electrical transport, magnetic susceptibility, heat capacity, and thermodynamic properties. We found that the temperature-dependent resistivity exhibits a bad metal behavior with a board peak around 200 K. The magnetic susceptibility of RhSb2 shows diamagnetism from 300 K to 2 K. The low-temperature specific heat shows a metallic behavior with a quite small electronic specific-heat coefficient. No phase transition is observed in both specific heat and magnetic susceptibility data. The Hall resistivity measurements show that the conduction carriers are dominated by electrons with ne = 8.62 × 10^(18) cm^(-3) at 2 K, and the electron carrier density increases rapidly above 200 K without change sign. Combining with ab-initio band structure calculations, we showed that the unusual peak around 200 K in resistivity is related to the distinct electronic structure of RhSb_2. In addition, a large thermopower S(T) about -140 μV/K is observed around 200 K, which might be useful for future thermoelectric applications.

A series of dust pollen samples was collected along N-S transects in east China (18°N to 53°N latitudes). sample sites extend from the cold-temperate zone in the north to the tropical region in the south. Pollen taxa characterize each region and reflect the natural and devastated vegetation as well as corre- sponding climatic zones. The quantitative pollen data can be used to estimate the spatial distribution of planted and introduced species. Valuable information of human disturbance of the natural forest is evaluated by quantitative comparison between dust pollen and in-situ pollen of protected forest. In addition, percentages of grass pollen vary regularly from north to south that is consistent with spatial distribution of net primary productivity in east China. Among all grasses, Artemisia and the Gramineae carry the clearest signal: their ratio increases northwards and therefore represent a suitable and con- venient tool for palaeoclimate reconstructions.
