Changes in the Spatial Structure of the Landscape of Isolated Forest Complexes in the 19th and 20th Centuries and Their Potential Effects on Supporting Ecosystem Services Related to the Protection of Biodiversity Using the Example of the Niemodlin Forests (SW Poland)
Authors: Badora Krzysztof , Wróbel Radosław
Published: May 2020

This study assesses the changes in the spatial structure of the landscape between 1825 and 2019 in the isolated, protected forest complex of the Niemodlin Forests. Based on the analysis of changes in this structure, a change the supporting ecosystem services related to the protection of biodiversity was proposed. The landscape metrics were used separately for the analysis of the structure of the whole landscape, and individual types of ecosystems were used in the research. There were no major changes in the share of individual types of ecosystems during the period under review. At the same time, a very large increase in built-up areas and tree stands was found in 1825. Landscape metrics point to internal changes in the landscape composition, which is important for the functioning of the landscape and is related to the fragmentation and increasing isolation of ecosystems. Changes in the share of the surface of individual types of ecosystems in the landscape do not provide enough information about the actual structural and functional changes and ongoing ecosystem support services. There has been ecosystem degradation that is associated with freshwater habitats—surface waters, marshlands, meadows and pastures, as well as ecosystem support services related to these habitats. Changes in the spatial structure of the landscape cannot be solely deduced on the basis of changes in landscape metrics that are calculated for the whole landscape. Changes in the spatial composition of individual groups of ecosystems should be analyzed. Landscape metrics are very helpful in studying changes in the structure and function of ecosystem services.
Agro-Pruning for Energy as a Link between Rural Development and Clean Energy Policies
Authors: Kulišić Biljana , Radić Tajana , Njavro Mario
Published: May 2020

Agrarian pruning and plantation removal (APPR) is a common residue from pomo-technical maintenance of orchards, vineyards, and olive groves, frequently overlooked by the energy sector. This paper sheds new light on the socio-economic role of APPR as solid biofuel. The paper suggests business models that could both alleviate energy poverty in rural areas and increase the competitiveness of perennial crop (fruits, olives, vine) production. The effects of mobilizing APPR potential via business models are estimated at the micro (households’ income) and macro (number of households affected, size of the investment, tax effect, CO2eq savings) levels in the Croatian setting. Contrary to classical energy planning, the paper provides an approach that fosters local use of bioenergy by linking rural development with renewable energy end-use. The approach linked pruning energy potential with 47% of Croatian rural households which allows creating an evidence-based policy for rural development utilizing APPR as a sustainable solid biofuel. The most attractive business model for Croatian rural areas is utilization of APPR as a solid biofuel. It could be used as an energy poverty alleviation measure, allowing savings per heating season equivalent to 5%–11% of the average disposable income per household. Net APPR influence at VAT tax is estimated at 5.5 million euro·y−1. The paper proves that using average values for APPR in energy planning could be misleading.

Alloys, based on TiAl and Ti3Al, are made with utilization vacuum — arc, plasma — arc, induction- garnisage, magnetoperating electroslag melting, electron — beam melting with intermediate capacity, electroslag melting in inert atmosphere under «active» fluxes with metallic calcium, induction melting in muchsectional crystallizator and cold crucible, argon — arc melting with unexpended tungsten electrode in copper watercooling crucible.
For connection of the details, that were made from these alloys, there were used welding by pressure, contact, electron — beam, diffusion welding.
Alloys, based on titanium aluminide, have essential defects — high brittleness and low plasticity, viscosity and resistance thermal impact strength.
Autors a lot of articles explaines these descriptions by structural special features of titanium aluminides and alloys on their bases, but does not consider possibilities of the influence by oxygen nitrogen, hydrogen admixtures.
In literature information about methods of determination gaseous admixtures (O, N, H) contents in titanium aluminides and alloys on their bases are absented.
Methods of determination oxygen, nitrogen, hyd­rogen contents in titanium aluminides on ana­lysers TC436, RO316, TN114, RH402 are created. Parameters of these methods are described in this article (temperatures of heating on graphite crucibles, times, masses of analytical samples).
Definition and Analysis of the Main Requirements for Laboratory Competence
Authors: Nykytyuk О. А. , Novikov V. М.
Published: May 2020

The work is devoted to the study of the actual issue of technical regulation and metrology — determination of criteria of competence of laboratories.
The results of the worldwide accreditation work are subjective in nature and therefore require continuous improvement in the assessment methods used to determine the compliance of laboratories with standard competency requirements.
The analysis of the main elements of the management system, which, in accordance with the Paretto principle, mainly form the competence of laboratories in its accreditation in the national body was held.
For the first time, the authors, with the involvement of all stakeholders, have analyzed and identified major competency requirements for laboratories across a wide range of DSTU ISO / IEC 17025: 2017 requirements.
Also, for the first time, the technology of peer review was applied to the analysis of the criteria of competence of laboratories.
The recommendations of ILAC, EA and EUROLAB international organizations for the criteria of competence of laboratories are analyzed in detail. Particular attention is given to the introduction of specific requirements for staff competence and accreditation criteria, which are in one way or another related to the competence of the laboratory staff.
It has been established experimentally (by the method of expert evaluation) that such elements of the management system as risk management, personnel management, internal audit, intralaboratory control and interlaboratory comparisons are considered today to be the most important in confirming the competence of a laboratory.

Background
. This study aimed to evaluate the effect of different pouring times and spacer thicknesses on the three-dimensional accuracy of casts made of 3D-printed custom trays. Methods. A partial edentulous maxillary model was scanned for fabricating custom acrylic trays. Twenty custom trays were created using a CAD/CAM system and divided into two groups in terms of their spacer thicknesses (2 mm and 4 mm). All the trays were designed with 2-mm thickness, multiple retentive holes measuring 2 mm in diameter, and three interior seating stops (two on the edentulous ridge and one on the incisal edge of the central incisors). Impressions were made using monophasic polyvinyl siloxane and poured in two different times (one hour and 24 hours after removal) with type IV dental stone. All the casts were scanned to measure three distances (inter-buccal cusps, inter-palatal cusps, and inter-fossa distances) between the two first premolars. The data were analyzed with two-way ANOVA and Bonferroni test at a significance level of 0.05. Results. There was no significant difference between the 3D accuracy of casts made using two different spacer thicknesses poured at 1-hour and 24-hour intervals. However, there was a difference between casts made after 1 hour and 24 hours when using custom trays with 2 mm of spacer thickness in terms of inter-buccal distance. Conclusion. There was no significant difference between the accuracy of casts made using custom trays with either 2 or 4 mm of spacer thickness, which were poured 1 hour or 24 hours after tray removal.
Historia Brittonum and 'Saxon Annals': A case for convergence in the historiography of post-roman Britain
Authors: Edwin Pace
Published: May 2020

Analysis here of chapter 66 of 'Historia Brittonum' suggests that its chronology diverges less from that of Bede and 'Anglo-Saxon Chronicle' than previously believed. The author's own testimony demonstrates that he misunderstood the significance of Roman consuls. His belief that consuls, and not emperors, ruled Rome after 388 led him to delete twentyfour years from the reign of Valentinian III. This in turn shifted every date in chapter 66 back some two decades. But when this single error is corrected, 'Historia Brittonum's' chronology becomes much more consistent with that of other works of early Insular historiography. Most significant, this apparent convergence mandates a comprehensive re-examination of all the early written sources for post-Roman British history.

Bayamo la ciudad incendiada en Cuba colonial. Condiciones de vida durante la diáspora poblacional entre 1869-1879
Authors: Madrigal León Diurkis Yarenis
Published: May 2020

El presente artículo es el resultado de una investigación de corte socio histórica que indaga en los acontecimientos ocurridos después de la quema provocada el 12 de enero de 1869 en la ciudad de Bayamo, territorio donde se iniciaron y acrisolaron las ideas independentistas contra el dominio español.El objetivo consiste en develar las condiciones de vida experimentadas por los moradores de Bayamo durante la diáspora poblacional entre 1869 y 1879, después de concretarse la quema de la ciudad. Para la indagación científica se implementó un profundo trabajo con documentos propios del período, además de la indagación detallada desde fuentes de transmisión oral.Posterior a la quema de la ciudad, la población se dispersó, desde entonces se estructuró y consolidó un proceso de emigración poblacional hacia diferentes zonas del oriente de Cuba y países cercanos. La metrópoli española incrementó severas formas de represión revestidas de asesinatos y crímenes, fundamentalmente contra las familias de los patriotas que iniciaron la guerra y el resto de los habitantes que continuaron el tránsito por las serranías. La ciudad se caracterizó por un perenne estado de ruinas y la población por un severo desgarramiento emocional que resultó patente durante las tres últimas décadas del período colonial.

Patronos, jerarcas y franquistas Actitudes y recursos coercitivos ante el surgimiento de la protesta obrera, 1962-1976
Authors: Ferrer González Cristian
Published: May 2020

Este artículo explorará la relación entre el surgimiento de la protesta obrera y el desarrollo de nuevos recursos para su contención y neutralización durante la segunda mitad del régimen de Franco. Focalizará en el caso de Tarragona, una ciudad catalana de industrialización reciente que hasta finales del franquismo figuró entre las provincias menos movilizadas de España. La ausencia de tradición contestataria, la falta de experiencia en el trabajo industrial o la memoria de la violencia fundacional del franquismo, fueron algunos de los elementos que condicionaron la aparición del movimiento obrero antes de la década de 1970. Incluso tras el acelerado proceso de industrialización de los años sesenta, el orden laboral y político permaneció bajo control de las autoridades y el surgimiento de la protesta socio-laboral se encontró frente a unas autoridades poco avezadas a combatirlo. El debilitamiento de los mecanismos de disciplinación laboral por parte del movimiento obrero y la impericia de las fuerzas policiales par descabezar las organizaciones que sostenían la protesta, propició el desarrollo de nuevas y diversificadas respuestas patronales, del sindicalismo oficial y de los apoyos sociales de la dictadura, que tras el desborde de la movilización tomarían caminos divergentes.
La Revolución cubana de 1895. El aporte de los viajes de Arístides Agüero a Perú, Chile y Bolivia.
Authors: Gallegos Claudio Antonio
Published: May 2020

El presente artículo tiene como objetivo analizar las redes desarrolladas por el Partido Revolucionario Cubano sobre Perú, Chile y Bolivia, con la intención de lograr apoyo a la insurrección cubana de 1895. Dentro de los estudios sobre la guerra de 1895 se evidencia una ausencia en lo que respecta a relaciones diplomáticas por parte de la República de Cuba. A través de correspondencia pública y privada se demuestra, entonces, como uno de los delegados de dicho partido, Arístides Agüero, construye relaciones de poder por medio de diversas acciones sobre la Región Andina Sur. Considerada la guerra como un hecho social complejo recurrente en la historia de la humanidad –desde una mirada sociológica y geopolítica-, se busca describir el impacto de dichas redes localizando sus ámbitos de realización, ya sean organizacionales, políticos o bélicos. Asimismo, se busca complementar los estudios acerca de un conflicto mayor como lo representa la independencia cubana.
Propiedad, modelos de negocio y poder en los albores del periodismo: Centro y periferia en la prensa en lengua(s) española(s) del siglo XVII
Authors: Díaz Noci Javier , Espejo Cala Carmen
Published: May 2020

Este trabajo pretende explicar qué modelos de negocio se perfilaron en los inicios del periodismo europeo y español (siglos XVI-XVII). Recogemos en él los resultados de investigación de nuestros trabajos previos sobre escenarios locales y casos particulares para intentar, a partir de ellos, diseñar un marco común de interpretación sobre la estructura de la propiedad y producción de los medios impresos en la Edad Moderna. El artículo se estructura en dos partes: en la primera, hacemos una tipología de los oficios y funciones relacionadas con la recopilación, producción y difusión de noticias, y su relación con el poder civil y eclesiástico. En la segunda nos referimos a un caso que podemos destacar como paradigmático, pues da idea de la notable complejidad que alcanza el periodismo como objeto de comercio ya en sus primeros siglos de existencia: el caso de Sevilla.
La (des)aparición de los monumentos. Materialidad e imaginarios en el panóptico de Ibagué, Colombia
Authors: Sánchez Rojas Fabián Andrés , Francel Delgado Andrés Ernesto
Published: May 2020

El panóptico de Ibagué es un bien de interés cultural de carácter nacional que ha decaído en estado ruinoso desde el año 2003, como consecuencia de un plan de restauración mediado por las deficiencias administrativas gubernamentales. Para estudiar su impacto en la sociedad, se abordó un estudio alrededor de los imaginarios de identidad, cultura y patrimonio asociados al panóptico, para lo cual se implementó un cuestionario y se contrastaron sus datos con diversas fuentes documentales en una dimensión histórica. La (des)aparición observada consiste en la disyuntiva entre la liberación del edificio por la demolición de sus muros perimetrales, con lo cual se inserta en las dinámicas urbanas -o aparición- y, simultáneamente, comienza un proceso de degradación física y simbólica –o desaparición-. Se concluye con la necesidad de que los procesos de intervención del patrimonio material se basen en los estudios sobre la identidad de los pueblos para su puesta en valor y legitimación, para evitar que los dispositivos arquitectónicos se conviertan en arbitrariedades particulares y agendas políticas.

Authors: Yarmaliza Yarmaliza , Farisni Teungku Nih , Fitriani Fitriani
Published: May 2020

Stunting is one of the effects of nutritional problems from past intake caused by a lack of macro and micro nutrient intake (such as protein, vitamin A, zinc), as well as the frequency of infectious diseases such as diarrhea and low birth weight. Kuala Pesisir sub-district has a prevalence of stunting in 2017 that is 39.2%. Purwodadi Village accounts for the highest stunting case, with 66 toddlers with stunting. The purpose of this study was to determine the effect of mothers' knowledge and attitudes on the provision of tempe broth as an effort to prevent stunting in infants in Purwodadi Village, Kuala Pesisir District, Nagan Raya Regency. This study uses a cross-sectional design with a population of 75 mothers who come from poor families and have toddlers, sampling using a total sampling technique that is as many as 75 mothers who come from misikin families. Data were analyzed by univariate, bivariate, and multivariate using multiple linear regression tests.The results showed a relationship between mother's knowledge and attitude towards the provision of tempe broth as an effort to prevent stunting in infants (P. Value <0.05). For the results of multivariate analysis shows that the mother's knowledge gives a stronger influence on the administration of tempe broth (Ex. B. 27, 28). The conclusion there is a very significant relationship between mother's knowledge and attitude towards the provision of tempe broth. Mother's knowledge gives a stronger influence on the provision of tempe broth as an effort to prevent stunting in infants. It is necessary to increase the education program for the community about the importance of nutrition in preventing stunting in infants.

Uma análise do feminismo para além do binarismo em “Enquanto meus pés balançam”, de JeisiEkê de Lundu
Authors: Santos de Matos Elisiane , Pereira do Sacramento Sandra Maria
Published: May 2020

O presente artigo trata a respeito da construção discursiva da identidade de gênero para além do binarismo, buscando entender como o constructo ideológico torna invisíveis as identidades de gênero inadequadas ao modelo ditado pela heterossexualidade compulsória do desejo. Tendo como corpus literário o poema “Enquanto meus pés balançam”, de autoria de Jeisiekê de Lundu, intenta-se compreender como a matriz cultural que torna não inteligível e, portanto, fora do campo da representação, a identidade de gênero que não decorre nem do sexo, nem do gênero.  Para tanto, utiliza-se como arcabouço teórico: Simone de Beauvoir (1980), Célia Amorós e Ana de Miguel Alvarez (2010), Judith Butler (2014), Pierre Bourdieu (2000), entre outros.

Face acknowledgement is a biometric framework used to recognize or check an individual’s identity against a dataset of images. In recent times, there have been several different approaches utilized to try to achieve high accuracy rates. This paper presents a system that enables an individual’s identity to be determined based on a matching of their facial structure against a previously stored database. The matching compares the frontal view of the face with the two-dimensional images of the head already stored. In our system, the input image is sometimes enhanced using histogram equalization, before the matching takes place using the Euclidean distance between the face to be identified and those already stored. The developed acknowledgement system provides an accuracy of 97.5%.

Nowadays Autism children find it difficult to interact socially with people emotions and make themselves isolated. This paper proposes Emotion detection for Autism spectrum disorder children (ASD). It is self-possessed of python libraries Open CV, Haar-cascade method and Age and gender prediction. Conversely, most existing methods rely on the detection of facial expressions of people in social media platforms such as snapchat use facial recognition technology and also detecting facial emotions from their Facial expressions in image. And for a better involvement of the children’s social behaviour, here a face is captured in real time and age, gender and emotions are predicted by Facial expression recognition (FER). This proposed system helps to improve the Autism children behaviour as they often observe the facial expressions of humans and try to imitate their emotions which make a huge difference in their behaviour.

Published: May 2020

There is a substantial curiosity in academia, the investment community and among manufacturers about the exhilarating opportunities offered by nano materials. Although a lot of applications for nanotechnology remain hypothetical, construction is one area where numerous ‘here and now’ applications have already emerged. While existing use is restricted, the market is likely to approach more than 500 million dollars within ten years. Concrete is most likely exceptional in the construction field, that it is the distinct material exclusive to business and hence, is the recipient of a reasonable quantity of research and development capital from the construction industry. SiO2 (Silica) usually is an integral part of concrete in the normal mix. On the other hand, one of the innovations made by the study of concrete at nano scale level is that particle stuffing in concrete can be enhanced by means of adding nano silica (NS), which results in the densification of the micro and nano structure of cementitious composite resulting in enhanced mechanical properties. In this research paper, the result of a thorough investigational analysis on the utilization of NS in addition to cement so that the strength and quality of concrete can improve has been achieved. The effect of various proportions of NS in concrete has been premeditated to evaluate the properties of NS based hardened concrete according to the standard concrete. The obtained outcomes after testing indicate that the addition of NS together with concrete has improved the mechanical behavior of concrete. The NS blended high strength concrete (HSC) shows a better compressive strength (CS) of 66.00 N/mm2 (MPa) after standard twenty eight days, which is an exceptional development over standard concrete. Each and every mixture containing NS in various proportions gave enhanced outcomes in comparison with the standard predictable concrete. RH (Rebound Hammer), UPV (Ultrasonic Pulse Velocity), SEM (Scanning Electron Microscope) and TEM (Transmission Electron Microscope) examinations further authenticate the above results.

Innovation has become the key determinant of any organization in “Staying Relevant”, irrespective of the product or service produced. Innovation comprises different concepts based on the application through the product and service Life-Cycle. Technological Innovation has become the governing factor out of all which ensures the successfulness of the Innovation. But Innovation involves great amount of risks which even leads to an organization into a catastrophic situation in the absence of an appropriate Risk Management Strategy. In developing a Risk Management Strategy it is imperative to have a precise knowledge on the impact of Risks related to Technological Innovation, which can be represented by weightages. This paper presents Risks related to Technological Innovation based on the Literature and attempt to establish a relationship among the risks which forms a Hierarchical structure related to Fuzzy – Analytic Hierarchy process (F-AHP). Information unveiled in the literature and the ideas shared by Industry Expertise were the basis for pairwise comparisons. Consistency of the Pairwise comparison has endorsed using the Consistency Ratio. Consistent pair wise matrices were converted into Fuzzy matrices which have been carried out Fuzzy-AHP in obtaining the weightages related to Technological Innovation Risks. The weightages derived, provide a clearer insight on contribution of different risks on Technological Innovation failures and hence giving heads-up on the risks which need prior attention. Furthermore this illuminates the effectiveness of the Risk Management Strategy by providing facts to decide on which risks need to be Ignored, Mitigated, Addressed or Transferred. Thus, precise application of the findings of this research will absolutely help in developing a copy proof Risk Management Strategy which would ultimately offers many opportunities to a business that cannot be realized otherwise.

Data security is protecting digital data, from the unwanted actions of unauthorized users, like cyberattack or data breach. Data is no longer said to be secure if it falls into the hands of hackers or those that would misuse it. Data is well secured and guarded within an organization. But, when its employees sell their access specifiers to their competitors, data is no longer protected. This could be avoided by advanced technology. The Identity-based approach is an approach to regulate access to a digital product or service based on the identity of an individual. This allows organizations to grant access to a variety of digital services using the same credentials, ensuring the accurate match between what users are entitled to and what they really receive, while also permitting other access constraints like company, device, location and application type(attributes) In our application, data is uploaded by an encryption format attached with the video mode and it is downloadable by the user only through the unique face detection mode. When a user tries to download the encrypted file, a notification is sent to four admins for better privacy reasons. Only upon acceptance from four of these admins, the file could be downloaded. The admins can authenticate the user using his face captured through face detection. This could be used at any level in an organization but is much efficient when no of users trying to access a file is limited. This provides high security and rejects unauthorized users. Breach of data leads to a decline in profits and incline in losses. This could be reduced if the data security could be ensured using face detection of a person who is trying to access the data.

Machine Learning is the study of algorithms and application of artificial intelligence. Artificial Intelligence is said to be the superset of machine learning. It aims to develop those programs which can learn and improves it upon increasing experience. It is designed to learn by itself. The aim is to detect pancreatic cancer using machine learning approach. Pancreas is responsible for secreting insulin which helps to control the blood glucose level in the human body. The paper aims to detect pancreatic cancer with the help of machine learning. The tumor is detected using image processing and is to be detected at the premature stage so that proper medication and treatment can be provided to increase the survival rate of the patient. The MRI image of pancreas obtained after MRI scan will be preprocessed and its noise is removed. The segmentation of MRI images will be performed using FCM algorithm. The tumor present in the image will be detected with the help of morphological process and multi clustering model. After Segmentation the image will be divided into various regions. With the help of the hybrid technique the primary and secondary regions are compressed and are used for telemedicine application. DWT is used for DE noising the image. GLCM features are extracted. The image then compared with the database images of pancreatic tumors and is classified as abnormal and normal with the help of BPN based classifier. The image is classified into abnormal and normal. The malignant image is considered as abnormal. The abnormal image is then segmented using SFCM and tumor part is clustered. After clustering the tumor part validation about the presence of pancreatic cancer is given.

High-performance VLSI systems are essential in real-time applications, in order to increase the performance of the VLSI systems, an approximate computing technique is followed where the performance of the circuit is enhanced by trading off it with a slight loss in the accuracy. These approximate circuits are used in error-tolerant applications, where output need not be accurate. This paper concentrates mainly on approximate adders, as they are major building blocks of DSP systems. The analysis of the Lower-part OR Adder for 4-bit addition and comparison of it with the precise adder i.e., Ripple Carry Adder using the mentor graphics tool in 90 nm CMOS technology are presented in this paper. Our experimental results show that there is 17%-70% savings in power dissipation, 4%-32% saving in the area, and 19%-84% savings in time due to approximate adder. As the LOA-2 and LOA-3 are performing optimally these two adders can be used for error-tolerant applications and based on the requirement LOA-2 or LOA-3 can be selected.

Solar tracking devices are quite effective for collecting maximum solar radiations but for vastly spread solar energy collection plant, their usage is suppressed due to large cost involvement. The best alternative to this problem is adjustment of tilt angle at most appropriate position. In this study monthly optimum tilt angle have been identified for a solar power plant setup-able site Kalth (φ 30.85046˚, L 77.06153˚), situated at Himachal Pradesh, India. For diffuse radiation estimation, an isotropic model has been used. By considering the impracticality involved in monthly tilt angle adjustment, various annual adjustment models have been formulated for two, three and four annual adjustments. In order to estimate the increment in solar insolation by adopting these models, Performance Enhancement (PE) have been computed from the conventional method of setting the solar collector tilt equal to latitude angle. The results show that PE is maximum for monthly optimum tilt angles followed by M-4 which is a three annual adjustment model. Based on PE requirement, any of the proposed models can be selected for setting up solar energy collection plant at suggested site.

Paddy cultivation is one of the major crops cultivated in India. Normally paddy cultivation is grown twice in a year, where the consumption of water is high during the cultivation. The monitoring of the water level continuously is a little bit tedious to the farmer. However, with the assistance of advanced technology, the burden on the farmer can be reduced. So, in this study, we are proposing the Wireless Sensor Network (WSN) architecture-based water level regulating system. WSN architecture consists of three nodes like sensor node, cluster head node, and sink node. With the assistance of the float sensor and ZigBee wireless communication module, the sensor node which is deployed in the paddy field senses the water level data and communicates to the sink node. The cluster head node monitors the sensor nodes of the cluster of paddy fields and controls the actuator concerning the water level. Sink node is generally located nearby farmer location, with the assistance of sink node the farmer observer the status of water level in their paddy fields in the LCD display. This system enhances in maintaining the optimal level of water and also reduces the burden on the farmer for continuous monitoring. Especially the sensor node follows the power management system, where the power interruption is avoided.
