Functional Confirmation Using a Medical X-Ray System of a Semiconductor Survey Meter

In recent years, semiconductor survey meters have been developed and are in increasing demand worldwide. This study determined if it is possible to use the X-ray system installed in each medical facility to calculate the time constant of a semiconductor survey meter and confirm the meter’s function. An additional filter was attached to the medical X-ray system to satisfy the standards of N-60 to N-120, more copper plates were added as needed, and the first and second half-value layers were calculated to enable comparisons of the facility’s X-ray system quality with the N-60 to N-120 quality values. Next, we used a medical X-ray system to measure the leakage dose and calculate the time constant of the survey meter. The functionality of the meter was then checked and compared with the energy characteristics of the meter. The experimental results showed that it was possible to use a medical X-ray system to reproduce the N-60 to N-120 radiation quality values and to calculate the time constant from the measured results, assuming actual leakage dosimetry for that radiation quality. We also found that the calibration factor was equivalent to that of the energy characteristics of the survey meter.

Determination of 8 Diuretics and Probenecid in Human Urine by Gas Chromatography-Mass Spectrometry: Confirmation Procedure

A fast and sensitive method for determination of 8 diuretics (acetazolamide, bendroflumethiazide, bumetanide, chlorthalidone, furosemide, hydrochlorothiazide, metolazone, triamterene) and masking agent (probenecid) in human urine using gas-chromatography with mass spectrometric detection is described. The extraction of the substances as function of the nature of organic solvent, mixing time and pH of aqueous phase was studied. The tandem mass spectrometry was used to increase selectivity of diuretics determination due to elimination of background interferences. Fragmentation reactions were studied for each compound and their collision energies were optimized to obtain the best selectivity. The results of method’s validation demonstrate its suitability in routine analysis for confirmation purposes.

Confirmation and Significance of Caledonian Metallogenic Epoch for Gold Deposits in South China

Caledonian gold deposits are widely distributed in South China. They are developed in both South China Caledonian fold belt and adjacent Proterozoic Jiangnan uplift. The host rocks are Proterozoic metamorphosed microclastic rocks in the Jiangnan uplift and Proterozoic and Cambrian strata, as well as Chengjiang and Caledonian igneous bodies in the South China fold belt. The distinct differences between the Caledonian and the most developed Yenshanian gold deposits in South China are reflected in age and host-rock type, relations to Yenshanian magmatic activities, element association, mineral assemblage and gold deposit type. The studies have proven that the Caledonian epoch is a principal metallogenic period of gold deposits in South China. This conclusion is of very important enlightening significance in exploration of Caledonian gold deposits in South China as well as in other Caledonian fold belts and adjacent uplifts in China.

股票期权作为一种长期激励机制雇我国虽已有一定的发展，但由于会计处理研究相对滞后，与国际惯例存在一些差距，这些问题包括股票期权会计确认观的选择、初始确认时间的确定、计量方法的选择等。对此，我国应借鉴国外会计处理理念和充分考虑我国国情。采取将股票期权确认为无形资产，拓宽所有者权益内涵，借助中介机构对股票期权进行估值，对于股票期权采用授予日作为计量日，使用公允价值计量经理股票期权，对股票期权的会计确认和计量进行补充和完善。以便股票期权这一长期激励机制在我国经济建设中更好地发挥应有作用。

RCDS:a right-confirmable data-sharing model based on symbol mapping coding and blockchain

The problem of data right confirmation is a long-term bottleneck in data sharing.Existing methods for confirming data rights lack credibility owing to poor supervision,and work only with specific data types because of their technical limitations.The emergence of blockchain is followed by some new data-sharing models that may provide improved data security.However,few of these models perform well enough in confirming data rights because the data access could not be fully under the control of the blockchain facility.In view of this,we propose a right-confirmable data-sharing model named RCDS that features symbol mapping coding(SMC)and blockchain.With SMC,each party encodes its digital identity into the byte sequence of the shared data by generating a unique symbol mapping table,whereby declaration of data rights can be content-independent for any type and any volume of data.With blockchain,all data-sharing participants jointly supervise the delivery and the access to shared data,so that granting of data rights can be openly verified.The evaluation results show that RCDS is effective and practical in data-sharing applications that are conscientious about data right confirmation.

生态修复目标司法确认的类型化构造

生态环境修复目标决定了生态环境修复责任的配置程度。司法确认生态环境修复目标的实践中存在损害前状态和功能的适用不合理、可接受风险水平被基本弃用和具体指向笼统模糊等问题,其原因在于司法中恢复原状思维的影响难以消弭以及现实危害的规制被过度关注。司法应当将生态环境修复目标划分为基线水平、人体健康可接受风险水平和生态环境可接受风险水平,然后根据生态环境的特质确认适宜的修复目标。对于价值较高的生态环境应当将其修复到基线水平,对于价值特殊的生态环境,即便在经济不合理的情况下,也应当将其修复到基线水平。对于人类密切相关的受污染生态环境应当将其修复到人体健康可接受风险水平。当生态环境可接受风险水平较为宽松之时可以考虑将其作为修复目标进行适用。

论客体对数据基本产权和分类确权的决定作用

数据二十条构建了基本数据产权,但要进一步确权立法,必须依据数据关系客体的不同对数据基本产权作出总体规定,并应根据客体类型作出分别规定。数据及其产品是新型民事关系客体,可被多人同时使用,其财产关系依合同产生具有相对性,这一客观规律决定数据产权为不同于所有权的有限产权。数据产权包括人格性权利和财产性权利,财产性权利以人格性权利为基础。数据确权立法的基本框架包括数据流通中当事人享有的数据持有权、加工使用权、数据产品经营权等基本数据财产权,著作类电子产品当事人的权利,数据直接生成产品当事人的权利,货币结算与比特币的规定,法院管辖、涉外法律适用、仲裁等内容。
