Using data of optic sensors and pigment content in leaves for efficient diagnostics of nitrogen nutrition
Received: February 23rd, 2022 ; Accepted: May 16th, 2022 ; Published: August 12th, 2022 ; Correspondence: [email protected] monitoring and diagnostics of a condition of crops permit to make prompt and
proper activities on dressing nitrogen fertilizers. This will allow the plants to use the nitrogen applied
efficiently, and therefore reduce their use in field. Since nitrogen that has not been utilized by plants
is able to escape into the atmosphere or be washed out of the soil with water. The most accurate
diagnostic method is to determine the chemical composition of plants, but it takes quite a long time
and requires laboratory conditions, which is not always possible in the field. One of the promising
methods is photometric diagnostics of crops using optical instruments. Experiment is carried out in
contrasting weather conditions, on soddy-podzolic soil with spring barley and spring rapeseed being
investigated. Results of research show the efficiency of using optic sensors (N-testers) for efficient
diagnostics of nitrogen nutrition of plants. The readings of the device (N-tester) were compared with
the concentration of a and b chlorophyll, determined by a chemical method. Results of diagnostics
with portable photometric device ‘Yara’ are correlating with concentrations of chlorophylls a
(r=0.96) and b (r = 0.91) in spring rapeseed. Moreover, correlation of rapeseed yield and
concentrations of chlorophylls a and b has quantity and inverse relation similar to device indication
(r = -0.81 and r = -0.70 respectively). Results of diagnostics with N-tester ‘Spectroluxe’ are
strongly correlating with chlorophyll concentration. Device indication correlates stronger with
chlorophyll b concentration in spring barley and chlorophyll a concentration in spring rapeseed
(rapeseed was investigated in dryer conditions). Thus, such a modern optical device as N-tester,
whose action is based on measuring the concentration of leafy chlorophyll, can replace chemical
methods and increase the efficiency of nitrogen fertilization, which means increasing the
productivity of plants and reducing the negative impact of unreasonable use of nitrogen fertilizers
Beautybar : Työkalu videopeli-kuvan analysointia varten
Tässä oppinäytetyössä esitellään itse kehitetty asteikko, joka on jaettavissa kuudeksi elementiksi: Sommittelu, valööri, väri, mittakaava ja tarkennus, objekti ja toteutuksen laatu. Asteikko perustuu sääntöihin, jotka fysiologisesti, objektiivisesti ja subjektiivisesti vaikuttavat visualisuuden havaitsemiseen ja innostavat pelaajaa. Asteikko perustuu klassisen maalaustaiteen opetuksen sääntöihin ja kokemukseeni videopelikuvien tekemisessä. Teoreettisen osan tekemistä varten analysoitiin erityisaloja, mm. psykologiaa, elokuvien tekemistä, videopeli- markkinointia, valokuvausta, biologiaa ja filosofiaa.
Tämän opinnäytetyön tarkoitus on antaa loogiset käyttöohjeet kuvan kauneuden analysointiin ja parantamiseen Beautybar -asteikon avulla. Opinnäytetyö jakautuu kahdeksi osaksi: teoreettiseen analysointiin sekä kokeelliseen osuuteen. Teoreettinen osa työstä keskittyy analysoimaan videopelikuvia ja tarjoaa selkeitä ohjeita parempien kuvien tekemiseen. Beautybar asteikkoon voi helposti palata taiteilijan luovuuden tasosta riippumatta. Asteikon teoreettinen osa sopii käytettäväksi eri tyylisissä videopelikuvissa tai muussa visuaalisessa suunnittelu- ja markkinointimateriaalissa, mutta asteikon käyttö on esitelty realistisien- ja sarjakuvamaisien videopelikuvien avulla opinnäytetyön käytännön osassa.
Beautybar on hyödyllinen työkalu peligrafiikoille, opettajille tai muille ammattilaisille, jotka analysoivat kuvia ja tarvitsevat vahvaa ihannekuvan kriteerien tuntemusta. Teoreettinen osa sisältää tärkeimmät selitykset kuvan rakentamisesta ja se sopii henkilöille, joilla ei ole taiteen tuntemusta. Käyttämällä Beautybar- mittausjärjestelmää kuka tahansa pystyy loogisesti analysoimaan ja kommentoimaan grafiikkaa ilman visuaalista koulutusta.The thesis focuses on my personal visual beauty measurement system, which contains six bases: composition, lighting, color, scale and detail, object and the quality of realization.
This measurement system is based on physical, social, objective and subjective rules, which have an effect on the visual detection and encourage players. For creation of the theoretical part, different specific fields have been analyzed, such as psychology, movie making, videogame marketing, photography, biology and philosophy.
This thesis is intended to provide the logical user a manual of beauty and to analyze and improve the image by using Beauty bar measurement system. The practical part of the thesis focuses on analyzing videogame images and provides clear steps to make them better looking for the players. The artist can easily return to the Beauty bar system regardless of the level of creativity. The theoretical part can be used in any realization style of videogame image or other visual design marketing material, but the measurement system presentation uses realism and cartoon style images.
Beauty bar system is based on classical painting rules and my personal experience of making videogame images. Beauty bar is a useful tool for the game artists, the teachers or other professionals, who need to analyze images and have a strong knowledge of the ideal image criteria. It is a useful tool for the artist's clients or employers because the theoretical part contains most important explanations of the image anatomy. By using Beautybar- measurement system, anyone is able to logically analyze and comment visual design without spending many years learning art, graphic design or other visual design program
Solving Boundary Value Problem for a Nonlinear Stationary Controllable System with Synthesizing Control
An algorithm for constructing a control function that transfers a wide class
of stationary nonlinear systems of ordinary differential equations from an
initial state to a final state under certain control restrictions is proposed.
The algorithm is designed to be convenient for numerical implementation. A
constructive criterion of the desired transfer possibility is presented. The
problem of an interorbital flight is considered as a test example and it is
simulated numerically with the presented method.Comment: 9 pages, 2 figure
La cirugía estética como relación de consumo
"La sociedad capitalista determina la creación de necesidades expresadas en el acceso a nuevos bienes y servicios que distan del consumo de subsistencia, lo que promueve la compra de productos simbólicos que proporcionan experiencias que despliegan satisfactores distintos al consumo racional. La proliferación de lacirugía plástica merece un análisis especial, pues en el año 2016, Colombia fue el tercer país latinoamericano -solo precedido por Brasil y México, respectivamente- donde más se realizaron procedimientos estéticos quirúrgicos, al punto de promoverse como un destino para el ""turismo de bisturí"" de forma institucional.Este artículo pretende caracterizar a la cirugía estética como producto de consumo, en el marco de una interpretación conforme al principio pro consumidor, con las consecuencias jurídicas de tal postura. Para ello, se analizará la relación jurídica surgida entre el cirujano estético y su paciente, para luego verificar si estase enmarca dentro del estatuto del consumidor, y por último se identificarán las consecuencias prácticas de incluir las obligaciones de este contrato dentro del derecho del consumidor, y así dilucidar la responsabilidad médica en virtud de daños causados a un paciente por este tipo de procedimientos.

Pós-crise do Subprime : inflação americana depois do Quantitative Easing
Este trabalho visa a compreensão dos motivos pelos quais, apesar da emissão de trilhões de dólares por parte do governo americano durante o Quantitative Easing, não houve elevação significativa do nível de preços na economia norte americana. Será feita uma apresentação da Teoria Quantitativa da Moeda e da Teoria Monetarista, expondo razões para que fosse esperado um aumento da inflação após a injeção de liquidez por parte do FED. Após o entendimento de ambas as teorias, serão abordadas as razões que levaram ao colapso do sistema financeiro americano. Também serão abordadas as medidas adotadas pelo FED para reverter os efeitos da crise, com ênfase para a compra de ativos por parte do governo americano, que fez com que a base monetária crescesse cerca de cinco vezes. Utilizando de revisão bibliográfica e análise de variáveis e agregados econômicos, será discutida a hipótese de que a moeda emitida durante o Quantitative Easing não chegou às mãos da população, logo não passou a de fato circular dentro da economia. Por causa disso, o aumento da base monetária não gerou um aumento do nível de preços.This work investigates the reasons why, despite the issuance of trillions of dollars by the US government during quantitative easing, there was no significant rise in the price level in the US economy. A presentation will be made of the Quantitative Theory of Money and the Monetarist Theory, exposing reasons why an increase in inflation was expected after the injection of liquidity by the FED. After understanding both theories, the reasons that led to the collapse of the American financial system will be addressed. The measures adopted by the FED to reverse the effects of the crisis will also be addressed, with emphasis on the purchase of assets by the US government, which caused the monetary base to grow by about five times. Using a bibliographical review and analysis of economic variables and aggregates, the hypothesis will be discussed that the currency issued during quantitative easing did not reach the hands of the population, therefore it did not actually circulate within the economy. Because of this, the increase in the monetary base did not generate an increase in the price level
