The interaction between infrared radiation and a power generator device in time is studied as a route to harvest infrared, and possibly other electromagnetic radiations. Broadening the spectrum of the usable electromagnetic spectrum would greatly contribute to the renewable and sustainable energy sources available to humankind. In particular, low frequency and low power radiation is important for applications on ships, satellites, cars, personal backpacks, and, more generally, where non-dangerous energy is needed at all hours of the day, independent of weather conditions. In this work, we identify an electric and an entropic contribution to the energy transfer from low power infrared radiation to the power generator device, representing electrical and thermal contributions to the power generation. The electric contribution prevails, and is important because it offers multiple ways to increase the voltage produced. For example, placing black-colored gaffer tape on the illuminated face doubles the voltage produced, while the temperature difference, thus the entropic contribution, is not sensitive to the presence of the tape. We recognize the electric contribution through the fast changes it imparts to the voltage output of the power generator device, which mirror the instabilities in time of the infrared radiation. The device thus acts as sensor of the infrared radiation’s behavior in time. On the other hand, we distinguish the entropic contribution through the slow changes it causes to the voltage output of the power generator device, which reflect the relative delay with which the two faces of the device respond to thermal perturbations.

为探究辐照灭菌对昭通酱的可行性,本文考察了不同剂量电子束辐照对昭通酱感官评分、微生物含量及挥发性成分变化的影响。结果表明,当电子束辐照剂量为3.68 kGy时,昭通酱感官综合评价较好,菌落总数、真菌、大肠菌群含量均达到卫生标准,昭通酱辐照前共鉴定出41种挥发性成分,辐照后共检出100种挥发性成分,辐照后挥发性成分主要由32种酯类、4种醛类、26种烯烃类、15种醇类、11种酮类、1种醚类、2种酚类和9种其它类物质组成。其中辐照剂量对醇类、酯类、醛类及其它类挥发性物质影响较大,辐照后酯类物质种类和含量增加明显,醛类和烯烃类物质含量下降。昭通酱辐照前挥发性成分主要有异丁醇、芳樟醇、4,7-二甲基十一烷和亚油酸甲酯,分别占总含量的36.90%、20.29%、11.70%和4.94%。辐照后昭通酱中挥发性成分主要有芳樟醇、亚油酸甲酯、苯甲酸乙酯、川芎嗪。辐照后异丁醇相对含量降低明显,而芳樟醇上升明显。根据结果可以得出3.68 kGy属昭通酱辐照灭菌的可靠剂量,其结果为昭通酱向高原地方特色产品的推广提供了参考信息。

回收硫是一种异常纯净的散装商品(纯度大于99．9％),在运抵终端用户的途中买方希望始终保持这一纯度。然而,每年国际贸易量超过20 Mt的这种高纯度原料,在到达终端用途目的地之前,几乎都要经过库存、大批量处置和转运,或常常通过铁路和船只长途运输。终端用户的接货纯度取决于上述过程对硫磺的处置方式。“亮黄色成型固体散装元素硫”并不是一个容易满足的技术要求。对以下问题进行了探讨:沿途混入的污染物的来源,如何最大限度地减少或消除这些污染物;如果无法消除,各种用途的最高容许含量是多少;这些物质留在硫磺中的后果如何;是否有更廉价而有效的保持产品纯度的方法;产品纯度对环境影响如何;杂质对处理、储存和运输设施是否会造成不必要的损害;保险保障和产品责任问题如何解决。

本文论述调速型液力偶合器对离心泵驱动的优越性,因为二者都具有类似的特性。锅炉给水泵采用调速型液力偶合器驱动与节流阀调节相比,其效率要高得多。而且给水泵与液力偶合器组装在一起,能够把起动时间(由静止状态到全速运转)缩短到8～10秒。大量的应用实例说明,在供热循环系统中,循环泵采用液力偶合器驱动,可把一些损失反馈到供热循环回路中去,这样就可使泵处在较宽和较高的效率范围内运行。在石油化工方面,调速型液力偶合器对石油管道泵和负荷泵的驱动,也正在得到推广应用。在电厂,对立式泵装置的冷却和冷凝循环的应用,也说明偶合器与立式泵的配套具有与卧式驱动相同的使用效果。最后,波力偶合器在泥浆管道上的应用,可按液流排量和流速以及输送能力对输送泵的转速进行调节,则可提高泵的寿命。

CD8^＋ natural killer T （NKT） cells from EBV-associated tumour patients are quantitatively and functionally impaired. EBV-induced CD8^＋ NKT cells drive syngeneic T cells into a Thl-bias response to suppress EBV-associated malignancies. IL-4-biased CD4^＋ NKT cells do not affect either syngeneic T cell cytotoxicity or Th cytokine secretion. Circulating mDC1 cells from patients with EBV-associated malignancies impair the production of IFN-T by CD8^＋ NKT cells. In this study, we have established a human-thymus-SCID chimaera model to further investigate the underlying mechanism of EBV-induced CD8^＋ NKT cells in suppressing EBV-associated malignancies. In the human-thymus-SCID chimera, EBV-induced CD8^＋ NKT cells suppress EBV-associated malignancies in a manner dependent on the Thl-bias response and syngeneic CD3^＋ T cells. However, adoptive transfer with CD4^＋ NKT cells alone inhibits T cell immunity. Interestingly, CD4^＋ NKT cells themselves secrete high levels of IL-2, enhancing the persistence of adoptively transferred CD8^＋ NKT cells and T cells, thereby leading to a more pronounced T cell anti-tumour response in chimaeras co-transferred with CD4^＋ and CD8^＋ NKT cells. Thus, immune reconstitution with EBV-induced CD4^＋ and CD8^＋ NKT cells synergistically enhances T cell tumour immunity, providing a potential prophylactic and therapeutic treatment for EBV-associated malignancies.

作者： Hu Haiqing Chen Di Zhang Dan Zhang lang Economics and Business School Xi'an University of Technology School of Economics and Finance Xi'an Jiao Tong University

By using historical simulation model and Monte Carlo simulation model, this paper measures the value of the market risk（VaR） of the oversea M＆A of Chinese resource-based enterprises. The research indicates that on the one hand Monte Carlo simulation method is superior to the historical simulation method in the accuracy of the measurement of market risk and characterization of extreme risk aspects. And the Monte Carlo simulation method based on the 95% confidence level is the best choice for measuring the market risk of oversea M＆A. On the other hand, most cases of oversea M＆A market risk are gradually reduced, but there are a few enterprises’ market risk tends to increase after M＆A. So these enterprises should be in time to find the existing problems, and adj.st the strategy of M＆A, eventually to improve the core competitiveness of enterprises in the market. The conclusion provides rich theoretical and practical basis for the successful operation of resource-based enterprises after oversea M＆A.
