Application of Trichoderma harzianum (T22) and Trichoderma atroviride (P1) as plant growth promoters, and their compatibility with copper oxychloride

Trichoderma strains are used in agriculture because they provide to the plants the following benefits: i) are rhizosphere competence and establish stable rhizosphere microbial communities; ii) control plant disease caused by pathogenic and competitive microflora, by using a variety of mechanisms; iii) improve vegetative growth, root development and yield; iv) make nutrients more available to the plant. In this work we have investigated the ability of T. harzianum T22 and T. atroviride P1 to improve plant growth of locally important horticultural crops: lettuce, tomatoes and peppers and to prevent disease in the greenhouse and field. The effect of the Trichoderma treatment was evaluated by determining the weight of fresh and dry roots and above ground plant biomass, measuring plants height, counting the number of emerged leaves (lettuce, tomatoes and peppers) and quantifying production (tomatoes and peppers). No disease symptoms were found during production, although Fusarium sp. strains pathogenic to tomato were detected in the soil. Compounds containing copper oxychloride are frequently used for fungal disease control in agriculture. In order to investigate the compatibility of T. harzianum T22 and T. atroviride P1 with copper oxychloride applications, the effect on mycelia growth was monitored in both liquid and solid medium. In general, the tests indicated a high level of tolerance of the Trichoderma strains to concentrations of copper oxychloride varying from 0.1 to 5 mmol/L.

Relations Between Red Edge Characteristics and Agronomic Parameters of Crops

The hyperspectral reflectance of the canopy and the leaves on the main stemfor six varieties, two each of rice corn, and cotton crops, were measured at different growth stageswith an ASD FieldSpec Pro FR^(TM) to analyze red edge characteristics forleaf area indices (LAI),aboveground biomass, as well as the chlorophyll, carotenoid, and nitrogen content, emphasizingcomparative differences on the red edge parameters. The results showed a 'double peak' phenomenonfor the red edge of the canopy spectra but not for the leaves. There were 'increase' and 'decrease'change rules for the red edge position, lambda_r, the red edge slope, D lambda_r, and the red edgearea, S_r, of the canopy spectra for all 3 crops with a 'blue shift' for lambda_r of the leafspectra for all 3 crops as the development stages progressed. For rice, corn, and cotton the LAI andfresh leaf mass had highly significant correlations (P < 0.01) to the red edge parameters lambda_r,D lambda_r, and S_r of their canopy spectra. Additionally, for all crops the chlorophyll-a,chlorophyll-b, total chlorophyll, and carotenoid content of the leaves all had highly significant (P< 0.01) correlations to their lambda_r. For rice, the nitrogen content of the leaves in g kg^(-1)and phytomassfor a unit area of land in g m^(-2) also had a highly significant (P < 0.01)correlation to lambda_r, D lambda_r lambda_r, and S_r of the canopy spectra.

Emmanuel Levinas： Hermeneutics, Ethics, and Art

This article draws attention to the subject of art in Levinas＇s thinking through consideration of his philosophical language, which is aided by images, metaphors, and idioms of art. The primary image that will accompany our discussion throughout this article is the image of art as shadow, which Levinas incorporates into the title of the essay which he devotes to the subject of art： ＂Reality and Its Shadow＂. Thinking about art from the perspective of Levinas means thinking about image and essence, about which is visible before us and which we cannot see, and about the different ways in which art can express itself. Levinas＇s theory of interpretation is grounded in and guided by the field of ethics and addresses the ethical aspects of interpretation. Levinas approaches the discourse of interpretation not out of na＇ivet6 but rather based on a deep understanding of the field of hermeneutics, with all its shortcomings and challenges. Thinking of hermeneutics from an ethical perspective is no mere addition to the discussion but the very crux of the matter. An attempt to understand interpretation as an act of exposing the truth encounters serious philosophical and logical difficulties, whether we are seeking to discover the intention of the artist, the intent of a specific work of art, or a hidden form within the work itself. The engagement with Levinas＇s theory of hermeneutics, however, raises a different question which is the focus of this article： Can Levinas＇s theory of interpretation be applied to the realm of artistic creation, and if so, how？ This question is sharpened by the difficulties that Levinas himself poses to his readers by designating art as the ＂shadow＂ of reality and drawing attention to the egoistic dimension of the artistic act.

Art making and expressive art therapy in adult health and nursing care:A scoping review

Objectives:While receptive art engagement is known to promote health and wellbeing,active art engagement has not been fully explored in health and nursing care.This review is to describe the existing knowledge on art making and expressive art therapy in adult health and nursing care between 2010 and 2020.Methods:Relevant studies and grey literature were searched and identified between March 17 and April 10,2020 from EBSCO,CINAHL,Medline and ERIC databases and a general Internet search.Following data charting and extraction,the data(n=42 papers)were summarized and reported in accordance with PRISMA-ScR guidelines.Results:In the included papers,both art making and expressive art therapy were seen in different health care and nursing contexts:yet not the home care context.The emphasis of art activities were group activities for chronically or terminally ill residents,adults aged 65 years or older.A focus on personal narrative was often seen,which may explain why art activities appear to be linked to acknowledging and building new strengths and skills,making meaning of experiences,personal growth,symptom alleviation,and communication;all used to foster collaboration between patients,patients’near-ones and health care professionals.Conclusions:Art activities appear to be suitable for every context and can promote personcenteredness and the measurement of nursing outcomes,and they should be considered an essential part of health and nursing care,nursing education and care for health care personnel.

Control of Ideal Heat Integrated Distillation Columns

The operation of an ideal heat integrated distillation column (HIDiC) is addressed. Five kinds of control configurations, i.e. single-loop control, multi-loop control, multivariable internal model control (IMC), modified multivariable internal model control (MIMC) and nonlinear process model-based control (NPMC), are designed and applied to the process. Simulation results demonstrate that all of the above control configurations are valid for product quality control. NPMC control configuration is found to be the best one among all the alternatives. It can readily realize setpoint transitions and conduct effectively against external disturbances. MIMC control configuration ranks second in the row for its regulatory responses to feed composition disturbances with relatively extended setting time. Next comes from the multi-loop control configuration, which is more or less handicapped by its greater deviations and overshootings. IMC control configuration can not compete with the multi-loop control configuration because it is extremely sensitive to operating condition changes. Single-loop control configuration is the worst one among all the mentioned control configurations. Its responses for the uncontrolled end products are extremely sluggish.

Identification of Stochastic Nature of Yarn Hairiness

Yam hairiness is a complex concept, which generally cannot be completely defined by a single figure. Hairiness can be considered as the fiber ends and loops standing out from the main compact yarn body. Uster hairiness system characterizes the hairiness by H value, i.e. the mean value of the total length of all hairs within one centimeter of yarn. The raw data HI are in fact realization of spatial process （hairiness spatial process -- HSP） and can be used for more complex evaluation of hairiness characteristics in the space and frequency domain. The main aim of this contribution is description of some tools for spatial characterization of yarn hairiness. The simple methods for complex characterization of lISP statistical behavior （stationarity, independence, linearity etc. ） are presented. The techniques based on the embedding dimension and correlation integral or long-range dependences evaluation are discussed. The selected methods are core of HYARN program in MATLAB. Application of this program for deeper characterization of artificial data and cotton type yam are shown.

Improved Disturbance Observer (DOB) Based Advanced Feedback Control for Optimal Operation of a Mineral Grinding Process

Advanced feedback control for optimal operation of mineral grinding process is usually based on the model predictive control (MPC) dynamic optimization. Since the MPC does not handle disturbances directly by controller design, it cannot achieve satisfactory effects in controlling complex grinding processes in the presence of strong disturbances and large uncertainties. In this paper, an improved disturbance observer (DOB) based MPC advanced feedback control is proposed to control the multivariable grinding operation. The improved DOB is based on the optimal achievable H 2 performance and can deal with disturbance observation for the nonminimum-phase delay systems. In this DOB-MPC advanced feedback control, the higher-level optimizer computes the optimal operation points by maximize the profit function and passes them to the MPC level. The MPC acts as a presetting controller and is employed to generate proper pre-setpoint for the lower-level basic feedback control system. The DOB acts as a compensator and improves the operation performance by dynamically compensating the setpoints for the basic control system according to the observed various disturbances and plant uncertainties. Several simulations are performed to demonstrate the proposed control method for grinding process operation.

The Metaphor of Narrative Woods in Eco＇s Work

This paper on Umberto Eco＇s contribution to the narration process, tries to identify the mainstream of modem studies of the text. I have tried to separate it as an entity, which together with other textual techniques and strategies shall create applicable theoretical messages towards an artistic creation. Eco＇s （1994） work itself, gives an opportunity to exemplify his theoretical claims. Using my examples, I have tried to show how a work of art can be rendered narrative, a subject to contemporary techniques and cooperativeness with the reader. One of the main issues I have explained is the time factor, seen from the linguistic and semiotic prospective. I consider that Eco＇s treatment of the relation between reality and fiction is of a semiotic nature. One of the main elements it contains （and definitely makes such a difference possible）, is the time factor. The delay （lingering） part treats works of art separately, and gives one of the ways to render artistic works readable, worth having an aesthetic value, in their way to transmitting a message to the audience.

National Identity in Conflict： The Reconstruction of King Ly Thai To on Vietnamese Screen

Born as Ly Cong Uan, Ly Thai To is the first king of the Ly Dynasty. The most important contribution of Ly Thai To in Vietnamese history is to move the capital from Hoa Lu to Dai La, and rename it as Thang Long （Ascending Dragon） in 1010. Nowadays, it is known as Hanoi. Ly Thai To promoted Buddhism, and reduced the centuries-old influence of Confucianism in the kingdom. The growth and prevalence of Buddhism brought about a long period of peace, where Buddhist literature consequently flourished with seminal achievements. Due to King Ly Thai To＇s enormous contributions, the Vietnamese have created several legends and anecdotes to mystify his life. Thus, although a historical figure, his life remains a mystery and controversy. In 2010, Hanoi celebrated the 1000th anniversary of Thang Long. On this occasion, Vietnamese historical films about Ly Cong Uan were produced. This created intriguing variations within historical facts, legends, and on-screen stories. This paper will explore the reconstruction of Ly Cong Uan＇s life from an adaptation studies perspective through four historical films： Legend of the Capital Relocation （Huyen su thien do）, Thang Long Aspiration （Khat vong Thang Long）, Ly Cong Uan The Road to Thang Long Citadel （Ly Cong Uan： Dtrong toi thanh Thang Long）, Child of the Dragon （Ngtroi con cua Rong）. This research also wants to clarify the issues of national identity, nationalism, and cultural interaction reflected through the representations of Ly Thai To in those cinematic products
