The performance of photovoltaic(PV)modules is affected by environmental factors such as irradiance and temperature,which can lead to a decrease in output performance or even *** study proposes an improved formula for calculating the real maximum power of PV modules by analysing the influence of irradiance and temperature.A simulation model is developed using PLECS software to simulate the global maximum power of PV modules under different environmental conditions and the results are compared with the calculated real maximum power.A power optimization scheme for PV modules is then proposed based on current equalization and constant voltage *** scheme employs a single-switch multi-winding forward-flyback converter to equalize the mismatched currents between cell strings,thereby enhancing the output *** proportional-integral controllers are utilized to achieve constant voltage control and obtain the real maximum power of PV *** models are built in the PLECS simulation platform to evaluate the performance of a global maximum power point tracking scheme based on the traditional perturb-and-observe(TPO)algorithm with current equalization,a segment perturb-and-observe algorithm without current equalization,and the proposed power optimization *** simulation results demonstrate that the proposed constant voltage control has greater efficiency than the TPO *** proposed scheme achieves a significant improvement in efficiency,with a 27.87%increase compared with the segment perturb-and-observe algorithm without current equalization.

Background: An interrupted family history, as is the case after taking someone into care, can complicate collecting family anamnesis data. In addition, the interrupted family history itself could be considered part of a person’s risk profile. Aim and methods: Literature analysis was conducted to examine whether there are scientific studies on health development after placement in out-of-home-care in order to recognise any existing medical characteristics that may be relevant for internal medical care. Results: There are few scientific publications on the health development of people after being placed in out-of-home-care. Direct reactions to the stress of being taken into custody include nausea and fever. However, effects that go beyond the acute situation and last into adulthood have also been described, such as AD(H)D, asthma, diabetes, cancer, hypertension and cardiovascular diseases (myocardial infarction, stroke), epilepsy and increased overall mortality in adulthood. Studies show that not only previous experience but also the stress of being taken into care is triggers for this. Conclusion: Information about a previous institutionalisation can hence be important for internal medical practice. The available scientific literature shows heterogeneous study methodology and no group of people with experience of out-of-home-placement has yet been scientifically accompanied for a long time period. Further studies on this could help to better weigh up the consequences of omitting and conducting an intervention for child/youth protection as well as to improve the medical care for this group of people.

【目的】本研究利用双孢菇(Agaricus bisporus)gpdII启动子,实现了碱性真菌漆酶PIE5(CcPIE5)在灰盖鬼伞(Coprinopsis cinerea)FA2222中的同源过表达。【方法】在mKjalke液体培养基中37℃培养7 d,漆酶活力达到(24.2±1.1)U/mL。纯化的CcPIE5在pH 8.0和60℃下表现出最佳催化活性。【结果】与已经研究报道的真菌漆酶不同,CcPIE5能耐受高浓度NaCl,当NaCl浓度从0升至1.5 mol/L时,CcPIE5的k_(cat)和K_(m)均呈下降趋势,表示CcPIE5在纺织印染废水脱色中有潜在应用价值。进一步在染料废水脱色应用中,以丁香酸作为介体,CcPIE5在pH 8.5和60℃条件下可高效降解(92.9±2.3)%的靛蓝胭脂红。通过LC-MS分析确认,Isatin 5-sulfonic acid(ISA)是靛蓝胭脂红降解的主要副产物。【结论】CcPIE5在高温、碱性和含盐条件下高效脱色染料,是处理环境和工业特定应用的理想选择。

In order to solve the problems resulted from dynamic access control in a userhierarchy, a cryptographic key assignment scheme is proposed by Prof. Lin to promote the performingability and to simplify the procedure. However, it may cause the security in danger as the userchanges his secret key; besides, some secret keys may be disclosed due to the unsuitable selectionof the security classes' identities. Through setting up a one-way hash function onto Lin's scheme,the proposed modification can greatly improve the security of Lin's scheme.

The mining process involves drilling and excavation, resulting in the production of waste rock and tailings. The waste materials are then removed and stored in designated areas. This study aims to evaluate the mechanical strength and the environmental and economic impact of using Coltan Mining Waste (CMW) as a substitute for aggregates in concrete and mortar production. To achieve this, the CMW needs to be characterised. The Dreux Gorisse method was primarily used to produce concrete with a strength of 20 MPa at 28 days. The mortars, on the other hand, were formulated according to the NF P 18-452 standard. The environmental impact of using CMW as substitutes for natural aggregates in the production of concrete and mortar was analysed using SimaPro software. The results showed that mortars and concrete made with CMW have comparable compressive strengths to the reference mortar and concrete;reduce the negative impact on ecosystem quality, human health, resources, and climate change. It has also been shown that the substitution of aggregates by CMW reduces the cost of concrete and mortar as a function of the distance from the aggregate footprint.

In the study, the digital multi-signature scheme, constructed by theintegration of one-way hash function and identification scheme, are proposed based on the ellipticcurve cryptosystem (ECC). To the efficiency in performance, the ECC has been generally regarded aspositive; and the security caused by the Elliptic Curve Discrete Logarithm Problem (ECDLP) is highlyalso taken highly important. The main characteristic of the proposed scheme is that the length ofthe multi-signature is fixed rather than changeable and it will not increase with the number ofgroup members.
