Background: Predictive models shed light on aboveground fungal yield dynamics and can assist decision-making in forestry by integrating this valuable non-wood forest product into forest management planning. However, the currently existing models are based on rather local data and, thus, there is a lack of predictive tools to monitor mushroom yields on larger ***: This work presents the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms and related ecosystem services in Pinus sylvestris and Pinus pinaster stands in northern Spain, using a long-term dataset suitable to account for the combined effect of meteorological conditions and stand *** were fitted for the following groups of fungi separately: all ectomycorrhizal mushrooms, edible mushrooms and marketed mushrooms. Our results show the influence of the weather variables(mainly precipitation) on mushroom yields as well as the relevance of the basal area of the forest stand that follows a right-skewed unimodal curve with maximum predicted yields at stand basal areas of 30–40 m2·***: These models are the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms in Pinus sylvestris and Pinus pinaster stands in northern Spain, being of the highest resolution developed to date and enable predictions of mushrooms productivity by taking into account weather conditions and forests’ location, composition and structure.

Mitochondrial dysfunction and endoplasmic reticulum stress(ERS) are global processes that are interrelated and regulated by several stress factors. Nitric oxide(NO) is a multifunctional biomolecule with many varieties of physiological and pathological functions, such as the regulation of cytochrome c inhibition and activation of the immune response, ERS and DNA damage; these actions are dose-dependent. It has been reported that in embryonic stem cells, NO has a dual role, controlling differentiation, survival and pluripotency, but the molecular mechanisms by which it modulates these functions are not yet known. Low levels of NO maintain pluripotency and induce mitochondrial biogenesis. It is well established that NO disrupts the mitochondrial respiratory chain and causes changes in mitochondrial Ca^(2+) flux that induce ERS. Thus, at high concentrations, NO becomes a potential differentiation agent due to the relationship between ERS and the unfolded protein response in many differentiated cell lines. Nevertheless, many studies have demonstratedthe need for physiological levels of NO for a proper ERS response. In this review, we stress the importance of the relationships between NO levels, ERS and mitochondrial dysfunction that control stem cell fate as a new approach to possible cell therapy strategies.

Unified Parallel C （UPC） is a parallel extension of ANSI C based on the Partitioned Global Address Space （PGAS） programming model, which provides a shared memory view that simplifies code development while it can take advantage of the scalability of distributed memory architectures. Therefore, UPC allows programmers to write parallel applications on hybrid shared/distributed memory architectures, such as multi-core clusters, in a more productive way, accessing remote memory by means of different high-level language constructs, such as assignments to shared variables or collective primitives. However, the standard UPC collectives library includes a reduced set of eight basic primitives with quite limited functionality. This work presents the design and implementation of extended UPC collective functions that overcome the limitations of the standard collectives library, allowing, for example, the use of a specific source and destination thread or defining the amount of data transferred by each particular thread. This library fulfills the demands made by the UPC developers community and implements portable algorithms, independent of the specific UPC compiler/runtime being used. The use of a representative set of these extended collectives has been evaluated using two applications and four kernels as case studies. The results obtained confirm the suitability of the new library to provide easier programming without trading off performance, thus achieving high productivity in parallel programming to harness the performance of hybrid shared/distributed memory architectures in high performance computing.

The adsorption of cobalt ions was evaluated using sediment samples from water bodies to investigate the adsorption properties of sediment and the behavior of these natural materials in the presence of nuclear and industrial waste. The two sediments(S1 and S2) were treated to eliminate humic and fulvic acids and then they were characterized by several techniques. The minerals found in both the sediments(X-ray diffraction) were quartz and albite; plus, goethite and muscovite in S1, and kaolinite and montmorillonite in S2. Point of zero charge(PZC) of S1 and S2 was 6.00 and 5.22, respectively. The specific area of S1(63.3 m2/g) is higher than S2(1.5 m2/g). Adsorption kinetics data for S1 and S2 were best fitted to the pseudo second-order model. The removal efficiency of S1 for cobalt was 96% with an adsorption capacity(qe) of 0.93 mg/g, and for S2 was 45% with a qeof 0.40 mg/g. The experimental data of the adsorption isotherms were adjusted to Langmuir and Freundlich models for S1 and S2, respectively. The thermodynamic parameters(enthalpy, entropy, and Gibb’s free energy) indicated that the adsorption processes were endothermic, spontaneous, and chemisorption mechanism. The results show that the adsorption capacities of the sediments depend on their composition. These water sediments have important adsorption properties for cobalt, and they can be used in the treatment of nuclear and industrial aqueous wastes.

近几十年中,中国的飞速发展引起了全球许多公司和企业家的关注,他们有意迈入中国这个充满活力但竞争激烈的市场。在此背景下,西班牙设计师在上海创立了年轻时装品牌Zurita Madrid。该品牌所处的行业在2018年的估值超过1.5万亿人民币,成千上万的品牌相互竞争,希望能吸引到更多的客户群。本文基于Zurita的社会积极性和环保举措,研究其营销策略、与顾客的关系以及品牌本身。为更好地了解该品牌的策略和工作背景,本文采用一手数据和二手数据(包括网络资料和出版书籍)开展研究。文献综述部分集中于客户参与理论的背景和现状,同时分析了该公司营销策略的核心内容——企业社会责任理论(CSR)。此外,作者还通过问卷调查开展了一项实证研究,以了解客户对中国企业社会责任的看法。尽管Zurita在社会和环保活动上投入了诸多资源,但经过对其社交网络和网络形象的深入分析,本文发现这些投入并未增加粉丝数量和网络影响力。本文采用了PESTEL、SWOT分析等策略及品牌识别棱柱模型等工具,判断这一结果的出现源于中国市场特征或是该公司的营销能力仍然有待提高。本研究创新性地重点关注了Zurita Madrid营销策略的特定要素。该公司的日常活动及营销活动都涉及大量的企业社会责任,这在时尚界十分罕见。有关外国公司在中国运营的英语研究也很少,因此我们希望弥补这一领域的空白。作者在研究中观察了公司改进营销策略的哪些内容可以提高客户参与度。调查结果以及其他建议的运用有望在保持对企业社会责任关注的同时,增强并改善公司的营销成果,提高收益。本文还为管理人员提供了一项包括人力资源在内的实施计划,并在结尾处呈现研究结论、研究过程的局限性,以及研究的进一步方向。
