穿越百年的硝烟

那一年,远渡重洋的货船首次拉开了罪恶的序幕;那一年,英吉利的炮火无情地笼罩着泱泱中原;那一年,虎门的硝烟毅然叩响了鸦片战争的大门。斯人已逝,精神永存,一百年后的今天,我依然在寻找着那硝烟中传承的精神。光阴迁流,季节变更,漫漫历史长河中,英雄们的身影,依然闪烁着璀璨的光辉。1840年,虎门海滩。一口销烟池静立于惊涛之上。

Use of Wild-Growing Mushrooms for Therapeutic Purposes in the Perm Territory, Russia

On the Penn Territory （Prikamie）, Russia, a systematic study of agarics and aphyllophoroid mushrooms has been conducted since 1975. The territory belongs to taiga. At present about 900 species of agarics and about 300 species ofaphyllophoroid mushrooms have been discovered. 139 species of Phylum Basidiomycota （131 species） and Phylum Ascomycota （eight species） can be used for therapeutic purposes. The most common are mushrooms from families Russulaceae （15 species）, Agaricaceae （11 species）, Polyporaceae, Strophariaceae （10 species each）. A considerable part of mushrooms （31 species） has bactericidal properties and 26 species can be used for treating malignant tumors.

Palliative care needs and symptom burden in younger and older patients with end-stage renal disease undergoing maintenance hemodialysis:A cross-sectional study

Objectives:To investigate the current situation of palliative care needs and the symptom burden in patients with end-stage renal disease(ESRD)undergoing maintenance hemodialysis(MHD),and to explore whether there are differences between younger and older patients.Methods:This cross-sectional study was conducted in the hemodialysis centers of two tertiary hospitals from November 2021 to June 2022.Participants were selected by convenience sampling.Sociodemographics,clinical characteristics,the Palliative Care Outcome Scale(POS),the Dialysis Symptom Index(DSI),and health-related quality of life(EQ-5D-3L)were used for evaluation.Descriptive statistics,between-group comparisons,and correlation analysis were used to analyze the data.Results:A total of 236 patients were enrolled,including 118 younger and 118 older patients.The total median(P25,P75)POS score was 16.0(12.0,23.0),and the score was higher in older patients(P<0.01).The mean total number of symptoms in MHD patients was 15.04±5.06,and the overall median symptom severity score was 59.0(52.0,71.0);these scores were higher in the older group(P<0.01).The most common symptom was dry mouth(91.5%),followed by itching(83.1%),and dry skin(82.2%).Additionally,palliative care needs were significantly associated with symptom burden and health-related quality of life(HRQOL).Conclusions:The results showed that patients with ESRD undergoing MHD have a significant symptom burden and moderate palliative care needs,which are more severe in older patients.Therefore,interdisciplinary teams should be formed to actively manage patients’symptoms and meet the physical,psychological,social,and spiritual needs related to palliative care to improve patients’HRQOL.

Different Growth Characteristics of Grewia mollis, Grewia tenax and Grewia villosa Under Nursery and Field Conditions

This study was carried out to assess the growth characteristics of Grewia moll＆, Grewia tenax and Grewia villosa under the nursery and field conditions. Two experiments were conducted at the farm of the College of Natural Resources and Environmental Studies, University of Juba, Khartoum, Sudan. Randomized complete block design with three replications was used. Morphological and physiological factors were measured. Seedlings height, number of leaves, number of branches and sub-branches were different （P 〈 0.05） among the three species at the nursery stage and under field conditions. Collar diameter showed significant difference among the species under field conditions. Physiological factors exhibited more significant variations in the field than at the nursery stage. Variations in growth characteristics were attributed to genetics differences and different growth habit, while variations in physiological factors （photosynthesis and transpiration rate） were attributed to differences in leaf structure, size and number of stomatal pores.

A Study on Preconditions Setting of Long-Term Contract between Manufacturer and Component Supplier

To provide a risk-sharing mechanism that encourages a component supplier and a manufacturer to expand their production capacity of components and products, many researches on SCM suggested that it is better for the SC players to connect a long-term contract with flexible preconditions before doing the decision-making of production capacity. With considering of the uncertainty of demand and integrity problems between SC players, it is difficult to set reasonable preconditions. As a result, under-investment problems still occur frequently. In this paper, after we had discussed the decision-making of production capacity with the preconditions by analyzing the character of the players, we verified the under-investment problem of the supply chain. In order to clarify the optimum preconditions to alleviate the under-investment problem, we also analyzed the relations between preconditions and supply capacity of the whole supply chain. In the last part of this paper, we proposed a method of preconditions setting in such uncertain situations.

Determining the Environmental and Economic Benefits of Life Cycle Assessment on Example of the Power Plants in Poland

The paper presents a method of life cycle assessment （LCA） to determine the impact of the electricity produced on the environment. To determine the environmental burdens and benefits the LCA technique is used, methodologically based on ISO 14040 series. In addition, the usefulness of this method to assess the energy sector has been shown. To evaluate the process, SimaPro software and the method of Eco Indicator 99 were used, which allows to get the results of the burden and benefit with taking into account three categories of damages： ecosystem quality, human health, and raw materials. This paper presents the impact of electricity generation on the environment in coal power plants. The article also points to the directions of the Polish energy sector and pointed to the need to determine the environmental risks associated with the production of energy. A detailed analysis by the method of LCA is made to compare the environmental impact of electricity generation in the Lagisza Power Plant and Turdw Power Plant. It is pointed to the difference in the results obtained. Moreover, the causes of the reported environmental impacts are discussed. Measures are identified which will help to reduce in the future the impact of the electricity produced on the environment during the production of electricity.

Is Greening the Building Envelope a Sustainable Design Practice？

Nowadays, the number of products and also of architectural projects, qualified as ＂sustainable＂, is ever more growing. Following this trend, architectural design may exploit the use of （eco） materials and components to promote a project as sustainable even without considering its impact on the environment; This can be defined as architectural greenwash. This paper considers the case of green envelopes with the aim to evaluate if these can be defined as sustainable design practice. Green envelopes provide environmental advantages together with the suggestion to a green aesthetics par excellence. In fact, the integration of vegetation in urban fabric plays an important role in improving ecological and environmental conditions of （and in） cities, although systems can have a high environmental burden. This paper aims to answer the question： Is greening the building envelope a sustainable design practice？ To do so, the paper provides a literature review which includes the main research developed regarding environmental burden, benefits and LCA （life cycle assessment） calculations of green envelopes.

Manipulation of parasite load induces significant changes in the structural-based throat color of male iberian green lizards

The honesty of structural-based ornaments is controversial. Sexual selection theory predicts that the honesty of a sexual signal relies on its cost of production or maintenance. Therefore, environmental factors with negative impact on individuals could generate high costs and affect the expres- sion of these sexual signals. In this sense, parasites are a main cost for their hosts. To probe the effect of parasites on the structural-based coloration of a lacertid species Lacerta schreiberi, we have experimentally removed ticks from a group of male Iberian green lizards using an acaricide treatment （i.e., the broad-use insecticide fipronil）. All individuals were radio-tracked and recaptured after 15 days to study changes in coloration in both the ultraviolet （UV）-blue （structural-based） and UV-yellow （structural and pigment-based） ornamentations after manipulation, as well as changes in endoand ectoparasitic load and body condition. Additionally, after the experiment, we measured the skin inflammatory response to a mitogen. The fipronil treatment was effective in reducing ticks and it was associated with a significant reduction of hemoparasite load. Throughout the season, individuals treated with fipronil tended to maintain the brightness of the UV-blue throat coloration while control lizards tended to increase it. However, individuals treated with fipronil that were not infected with hemoparasites significantly reduced the brightness of the UV-blue throat color ation. Individuals with a higher initial tick load exhibited a lower UV saturation increment （UV-blue） and a higher brightness increment （UV-yellow） during the experiment. Overall these results experimentally support the idea that parasites adversely influence the expression of the structural-based coloration of male Iberian green lizards. This adds evidence to the hypothesis that sexual ornaments in lizards function as honest signals.
