An Early Detection of Heart Disease using Machine Learning(recurrent neural network)
Authors: Shuvo Shahnewaz
Published: March 2023

People are obsessed with daily life, work, and other things while neglecting their health. Due to the hurried lifestyle and disregard for the health, the number of people getting sick every day is increasing. The majority of the population is afflicted with an illness such as heart disease. Heart diseaseshave been the leading cause of death on the globe during the last several decades, and have risen to become the highest existing condition on the earth. As a result, a reliable, accurate, and practical approach to the diagnosis of such disorders in time for adequate treatment is required. Numerous machine learning algorithms have recently been used by several researchers to aid the medical system and experts in the detection of heart-related disorders. To simplify the examination of large and complicated datasets, Machine Learning (ML) methods and techniques have been used on a variety of medical datasets. This research examines the performance of a variety of models based on such methods and techniques. Researchers use a variety of data sets and machine learning approaches to analyze large amounts of complicated medical data, assisting doctors in the prediction of heart disease. We'll provide support for RNN, Logistic Regression, and ANN methods. These algorithms are used to predict heart disease based on features. The efficacy of different machine learning methods is compared in this research. The objective of this study is to use a machine learning technique to estimate cardiac disease and then analyze the results

Reducing elderly home health care cost by developing a cloud based digital platform
Authors: Baijal Shobhit
Published: March 2023

The population among elderly people is increasing day by day in the United States

and also around the world. There are many devices, products and services which are available

for elderly people to get care. But, none of them offer affordable services, especially in the USA

where the average cost is enormously high. This has resulted in more elderly people working till

their last breath in order to survive as they don't have enough savings to get care. This paper

provides an overview of possible solutions where the cost of elderly care can be reduced using

a cloud based digital application that can provide a marketplace of caregivers (Nurses,

Veterans, Law Enforcements Officers, College Students) to serve the elderly people. Another

solution which this paper will talk about is a wearable sensor device where it can track the real

time data and through machine learning algorithm it can learn to predict/monitor the elderly’s

health condition and send SOS.
Participation in Project Planning and Implementation
Authors: Sharma Dhakal Vivek
Published: March 2023

The debate on the need to adopt a participatory approach in planning and implementing development projects and programmes has increased significantly. This paper explores the role of participation in project planning and implementation in the field of development. This study critically analyses the role of a participatory approach in project planning and implementation in practice through a review of literature. There are contentious viewpoints on the significance of the participatory approach in development practise and claim that it lacks evidence of community empowerment. However, this study espouses that the optimum advantage of adopting a participatory approach in the planning and implementation of projects in practice essentially depends on how participation is conducted.
Threat Modeling Through Detection, Prevention & Classification of Leading-to-Vulnerability Code Smells
(LVCs)
Authors: Malik Shah Jahan , Batool Komal
Published: March 2023

Code smells are usually ignored as they are neither a bug, nor a vulnerability. Quality engineers and, specially, security architects ignore them. As some of the code smells may lead towards vulnerability which may further be exploited by the hackers, therefore, such vulnerable code smells must be considered and further mitigated by threat modelers. In order to provide a repository of such code smells to security designers, a process had been devised and experimented. During the execution, various web applications had been passed through SAST and resulting code smells had been extracted and then inserted into a new dataset via Python. Later on, the code smells deposited in the dataset had been classified into various categories. Finally, machine learning algorithms had been assessed through WEKA and the fastest as well the most accurate algorithm had been selected. Current security standards do not ensure mitigation of threats caused by leading-to-vulnerability code smells, till to date. Typically, threat modelers assess security of a system through modeling threats via CIA, STRIDE and LINDDUN standards on its DFD and various architectural / infrastructural diagrams. Unless, they do not know that exploitable vulnerability still exists even after performing all secure design principles, the system would still be open to attacks. Our hypothesis was that vulnerable code smells still exist even after complying with all threat modeling standards. In the end, descriptive and inferential statistics had been used to analyse the results as well as test our hypothesis.
Mobile forensics techniques, tools and intrusion detection
Authors: Kumar Agnivesh
Published: March 2023

As the number and type of mobile devices increasers, so does its popularity thus making it a crucial part of one’s life. This super involvement of these devices makes them prone to anti-social behavior of humans like crime and stuff. This makes mobile devices an integral part of forensic procedure. The goal of the mobile forensic procedure is to retrieve digital evidence or relevant data from a mobile device in such a way that the evidence is preserved in a forensically sound state. To achieve this, the mobile forensic procedure must start with precise guidelines for seizing, isolating, transporting, storing for investigation, and proofing digital evidence coming from mobile devices. The process of mobile forensics is usually similar to that of other fields of digital forensics. However, it is important to note that the mobile forensics process has its own unique characteristics that must be taken into account. Correct approach and guidelines may be a necessary precursor for successful outcomes when examining mobile devices.

The following explanations are based on the central reference points and results of the basic research project on psychosocial risks in the world of work, which was funded by the Swiss National Science Foundation (SNSF). The aim of this project was to develop a formative risk assessment of psychosocial risks in the world of work with a special focus on the dynamic interdependencies between gainful employment and care work as well as structural work stress and subjectively perceived work stress. The result of this project is a theoretical-generic model of a formative risk assessment, which can be specifically configured for different stakeholder groups and was operationalized as a psychotherapeutic medical product via the Innosuisse project "SELBA" (Self Recognize, Understand, Change and Monitor Work Stresses and Strains).
Estimation of stresses in a massive granite using laser ultra-sonic testing and stress memory effect
Authors: Kašpar Ondřej , Kravcov Alexander , Štoller Jiří , Kubeček Petr , Vnuk Radovan , Zušťák Zbyněk
Published: March 2023

This paper addresses in-situ stress-estimation methods based on the Kaiser effect. The physical and mechanical properties of granite, diorite, and granodiorite samples selected at different depth intervals of the core obtained from a wellbore were examined. The ultimate uniaxial compressive strength, modulus of elasticity, and Poisson’s ratio of the rock samples were determined using presses and strain gauges. Also, local longitudinal and shear wave velocities were measured using a high-accuracy laser-ultrasonic system with a view to assessing the structure of the samples. Based on the resulting elastic wave velocity maps, samples with no obvious discontinuities were chosen. These undisturbed samples were subjected to uniaxial compression and their acoustic emission was simultaneously measured. In-situ stresses were estimated from the results of the interpretation of acoustic emission measurements. The experimental in-situ stresses were compared with the results of a numerical simulation. The ratio of the estimated in-situ stresses to the calculated ones is within the range from 0.81 to 1.11. This means that the laser ultrasonic and acoustic emission methods make it possible to effectively estimate in-situ stresses in a rock mass and assess the degree of rock mass damage.
Water quality image classification for aquaculture using deep transfer learning
Authors: Guo Hao , Tao Xunlin , Li Xingcun
Published: March 2023

With the development of high-density and intensive aquaculture production and the increasing frequency of water quality changes in aquaculture water bodies, the number of pollution sources in aquaculture ponds is also increasing. As the water quality of aquaculture ponds is a crucial factor affecting the production and quality of pond aquaculture products, water quality assessment and management are more important than in the past. Water quality analysis is a crucial way to evaluate the water quality of fish farming water bodies. Traditional water quality analysis is usually obtained by practitioners through experience and visual observation. There is an observability deviation caused by subjectivity. Deep transfer learning-based water quality monitoring system is easier to deploy and can avoid unnecessary duplication of efforts to save costs for aquaculture industry. This paper uses the transfer learning model of artificial intelligence to analyze the water color image automatically. 5203 water quality images are collected to create a water quality image dataset, which contains five classes based on water color. Based on the dataset, a deep transfer learning-based classification model is proposed to identify water quality images. The experimental results show that the deep learning model based on transfer learning achieves 99% accuracy and has excellent performance.
Biodegradation of Indigo Carmine Dye by Laccase from Bacillus licheniformis NS2324
Authors: Chopra Navleen Kaur , Sondhi Sonica
Published: March 2023

Indigo carmine dye is used in many industries like textile, paper, cosmetics, etc. It is specially used in textile industries for dyeing denim. The untreated water discharged from these industries, especially the textile industry, poses a significant environmental threat. The conventional physicochemical methods used in treating industrial effluent are very expensive and cause secondary pollution. In the present study, an extracellular laccase-producing Bacillus licheniformis NS2324 was isolated, and a crude enzyme was used to degrade indigo carmine dye. The conditions needed for decolorisation were standardised. Optimisation studies for dye decolorisation by NS2324 laccase revealed that the enzyme was able to decolorize dye efficiently at 50 oC temperature, pH 8, with an enzyme dose of 10 IU/ml after 6 hours. Up to 96.79±1.06 per cent decolorisation was achieved under optimised conditions without the use of any mediator of laccase. Complete degradation of indigo dye by laccase in the absence of mediator makes the present study very useful for treating textile effluent from the denim industry.

Authors: Pandey Vidya Shanker , Agrawal Anil Kumar , Dubey Ashish
Published: March 2023

This paper presents the successful implementation of the Life Cycle Assessment (LCA) approach for the sustainable development of a defence product.  Alternative designs of this product are evaluated from the environmental burden perspective.  The products considered are water bottles used by the armed forces in places like the Siachen glacier, where the environmental factors are of great concern.  From the environmental degradation perspective, the suitability of three existing bottle types has been analysed using LCA and Life Cycle Impact Assessment (LCIA) approaches on SimaPro software for each of its components and the bottle as a whole.  Using this software, uncertainty analysis has also been carried out by conducting a Monte Carlo simulation for a reasonable confidence level.  The latest design was found to have the least environmental burden, being 82.62% less compared to the first design.  To augment the environmental performance further, the best design was again reviewed by carrying out component level analysis to identify feasible alternative materials that would be functionally equivalent but with lower environmental impact.  It suggested switching to lower impact material for the cap and cap cover for the proposed design.  With the adoption of the changed material, the environmental performance improved by 10.61 % as compared to the best design and 84.46 % compared to the earliest design.

Published: March 2023

Background

The transradial approach (TRA) to coronary angiography reduces vascular complications but is associated with greater radiation exposure than the transfemoral approach (TFA). It is unknown whether exposure remains higher when TRA is performed by experienced operators.

Methods

Patients were randomly, prospectively assigned to TRA or TFA. The primary end point was patient radiation dose; secondary end points were the physician radiation dose and 30-day major adverse cardiac event rate. Coronary angiography was performed by experienced operators using a standardized protocol.

Results

Clinical and procedural characteristics were similar between the TRA (n = 150) and TFA (n = 149) groups, and they had comparable mean (SD) radiation doses for patients (616.51 [252] vs 585.57 [225] mGy; P = .13) and physicians (0.49 [0.3] vs 0.46 [0.29] mSv; P = .32). The mean (SD) fluoroscopy time (3.52 [2.02] vs 3.13 [2.46] min; P = .14) and the mean (SD) dose area product (35,496.5 [15,670] vs 38,313.4 [17,764.9] mGy·cm2; P = .2) did not differ. None of the following factors predicted higher radiation doses: female sex (risk ratio [RR], 0.69 [95% CI, 0.38–1.3]; P = .34), body mass index >25 (RR, 0.84 [95% CI, 0.43–1.6]; P = .76), age >65 years (RR, 1.67 [95% CI, 0.89–3.1]; P = .11), severe valve disease (RR, 1.37 [95% CI, 0.52–3.5]; P = .68), or previous coronary artery bypass graft (RR, 0.6; 95% CI, 0.2–1.8; P = .38).

Conclusion

TRA for elective coronary angiography is noninferior to TFA when performed by experienced operators.

Published: March 2023

Este artigo trata da participação da infância no contexto brasileiro a partir de duas pesquisas que abrangeram as formas de atuação das crianças no cenário nacional amplo e no espaço de uma escola pública situada em área periférica da cidade do Rio de Janeiro. Inicialmente, analisamos os conceitos de participação, infância e política, tendo como base o campo das ciências sociais e humanas. Em seguida, apresentamos a pesquisa que procurou construir um cenário das formas de participação no contexto brasileiro e a outra que mostra a atuação das crianças em seu espaço escolar. Destaca-se que as ações propostas que têm as crianças como atores trouxeram importantes elementos para refletir o tema da participação política. Ao indagar, na perspectiva das crianças, sobre o que é ser estudante de uma escola pública no Brasil, buscamos entender quais caminhos o desempenho e/ou a construção desse ofício abre para a participação. O ofício de estudante, que na nossa sociedade faz-se obrigatório, carrega uma dimensão geracional, uma vez que se trata de um papel que os mais velhos designam e esperam que as crianças desempenhem socialmente. Nesse embate, acordos e desacordos, consensos e dissensos são postos em cena, possibilitando (ou não) a ação desses indivíduos.
Nebulosa de lo público en una escuela chilena: Un estudio de caso
Authors: Redon Silvia , Vallejos Natalia , Belaustegui Camila
Published: March 2023

El artículo que se presenta expone los resultados de una investigación con estudio de caso único e intrínseco, en una escuela pública de Chile.  El estudio analiza la nebulosa de lo público en un centro educativo que reproduce una cultura confesional adscrita a la religión católica. El sello identitario del proyecto educativo estudiado surge históricamente desde el mundo privado-confesional católico; sin embargo, al ingresar y traspasarse a la administración pública, se mantienen las prácticas ideológicas que le sustentan. Este artículo tiene por objetivo discutir el sentido de lo público en la educación, a partir de las tensiones que emergen desde una normativa confesional como un orden de “ser” preestablecido y excluyente, en vez de construido socialmente e inclusivo, que hace borroso el sustento ético político de la convivencia democrática, lo común y lo público.  En los resultados, emergen categorías analíticas vinculadas con: 1) la cultura escolar cristiano-católica; 2) la pseudo-participación estudiantil en una cultura adulto-centrista; y, 3) el clasismo relacional como crítica a la inclusión, evidenciando contextos de democracia tutelada y de exclusión a la diversidad y la diferencia.

Published: March 2023

The manufacture of cement is often criticized to produce high CO2 emission to environment. Reducing cement in construction is believed to be the solution for better environment. Portland pozzolan cement (PPC) is known as a more environmentally friendly cement which substitutes some portion of cement clinkers with pozzolanic materials such as fly ash. Another material which is considered as green material is Geopolymer. The purpose of this study is to investigate the durability of mortars made of PPC and geopolymer in the corrosive environment. The geopolymer mortar was made of fly ash with 25% white soil substitution, and also 8M NaOH and Na2SiO3 as activators. The corrosive condition was simulated by Sulfuric Acid solution (H2SO4) with a pH of 4. The durability of the two types of mortar was investigated by testing their compressive strength, direct tensile strength, porosity, density and the changes of mass and physical shapes after immersion. The results show that the immersion of the mortars in a solution of pH 4 sulfuric acid does not make any major effects on the performance of the PPC mortar. However, the performance of geopolymer mortar with 25% white soil substitution decreases after being immersed in sulfuric acid solution.
Periodic solutions to a class of distributed delay differential equations via variational methods
Authors: Xiao Huafeng , Guo Zhiming
Published: March 2023

In this article, we study the existence of periodic solutions to a class of distributed delay differential equations. We transform the search for periodic solutions with the special symmetry of a delay differential equation to the problem of finding periodic solutions of an associated Hamiltonian system. Using the critical point theory and the pseudo-index theory, we obtain some sufficient conditions for the multiplicity of periodic solutions. This is the first time that critical point theory has been used to study the existence of periodic solutions to distributed delay differential equations.
Urbane Reproduktionskämpfe
Authors: Uhlmann Sarah
Published: March 2023

Spätestens seit der Finanzkrise erleben die wohnungspolitischen und städtischen Bewegungen einen neuerlichen Aufwind. Die Virulenz der Proteste wirft die Frage auf, um welche Form sozialer Kämpfe es sich dabei handelt. Der vorliegende, theoretisch ausgerichtete Artikel möchte daher eine Klassifikation urbaner sozialer Bewegungen (USB) entwickeln.

Um die USB gesamtgesellschaftlich zu verorten, werden stadtsoziologische mit solchen politökonomischen Ansätzen verknüpft, die ein erweitertes Verständnis von der Funktionsweise des Kapitalismus vertreten. Im Anschluss an Analysen von Klaus Dörre, David Harvey und Nancy Fraser wird dargelegt, wie in Krisenzeiten nicht-ökonomische Sphären und urbane Räume für die Akkumulation erschlossen werden. Dieses Profitstreben jenseits der Lohnsphäre soll ins Verhältnis zu den städtischen Protesten gesetzt werden.

Insofern die USB von der aktuellen Akkumulationsweise hervorgerufen werden, lassen sich diese als so genannte erweiterte Klassenkämpfe in der Reproduktionssphäre deuten. Da die städtischen Proteste zugleich mit bestimmten Möglichkeiten der Kollektivierung einhergehen, stellt der Bereich der sozialen Reproduktion nicht nur ein Terrain dar, auf dem sich die Krise entfaltet. Vielmehr tragen die Kämpfe um soziale Reproduktion zur sozialen Transformation bei.
Kommunale Bürgerbegehren und die Wohnungsfrage. Der ‚Mietentscheid‘ in Frankfurt und sein schwieriges Verhältnis zur institutionellen Politik
Authors: Schipper Sebastian
Published: March 2023

Am Beispiel des kommunalen Bürgerbegehrens Mietentscheid in Frankfurt am Main argumentiert der Beitrag erstens, dass es primär soziale Bewegungen sind, die innovative Vorschläge zur Lösung der Wohnungskrise entwickeln, welche auf einen strukturellen Umbau der Wohnungsversorgung entlang der Leitlinien Bezahlbarkeit, Dekommodifizierung und Demokratisierung abzielen. Allerdings zeigen sich institutionelle Politik und politische Administration im Verhältnis zu wohnungspolitischen Bewegungen oft verhärtet. Der Mietentscheid steht daher zweitens zugleich sinnbildlich für eine postneoliberale Konstellation, in der zivilgesellschaftliche Initiativen zwar großen gesellschaftlichen Zuspruch erfahren, jedoch von staatlichen Entscheidungsträger*innen mittels diskursiver Strategien der Delegitimierung, juristischer Strategien der Verzögerung sowie politischer Strategien der selektiven Einbindung ausgebremst werden. Obschon kollektive Akteure wie der Mietentscheid unter Umständen gewisse Zugeständnisse durchsetzen können, bleibt ein grundlegender Paradigmenwechsel in der Wohnungspolitik blockiert.
Soziale Bewegungen und der (nicht-)responsive Staat
Authors: Vollmer Lisa
Published: March 2023

Am 26. September 2021 stimmten fast 60 % der wahlberechtigten Berliner:innen für die Enteignung und Vergesellschaftung großer privater Wohnungsbestände. Dieser Aufsatz widmet sich der Frage, warum die gewählten Vertreter:innen der Berliner:innen den ausdrücklichen Wählerwillen (noch) nicht umsetzen. Warum reagieren entscheidende staatliche Institutionen nicht angemessen auf von sozialen Bewegungen organisierten öffentlichen Druck und noch nicht einmal auf die repräsentative Manifestation der öffentlichen Meinung in Form eines Volksentscheids? Nach gängigen Theorien der staatlichen Responsivität müsste die Mieter:innenbewegung und die Kampagne Deutsche Wohnen & Co Enteignen deutlich stärkeren Einfluss auf die institutionelle Wohnungspolitik haben. Warum können diese Theorien die Nicht-Responsivität staatlicher Akteure nicht fassen? Um sich diesen Fragen zu nähern, verfährt der Aufsatz in drei Schritten. Zunächst stellt er den Responsivitätsansatz vor. Anschließend beschreibt er empirisch die Reaktionen unterschiedlicher staatlicher Akteure und Institutionen auf den Enteignungs-Volksentscheid. Auf dieser Basis entwickelt er zum Schluss eine Kritik des Responsivitätsansatzes sowie Ansätze einer Retheoretisierung.
An integrated adaptive Kalman filter for improving the reliability of navigation systems
Authors: Almagbile Ali , Wang Jinling , Al-Rawabdeh Abdulla
Published: March 2023

Integrated GPS/INS using Kalman filter is the best technique for improving navigation accuracy. Assuming that the covariance matrices are known and constant, a conventional Kalman filter (CKF) is usually used, however, when they are unknown and time-varying, several adaptive estimation approaches have to be developed to estimate the statistical information of the measurement (R), process (Q), and state (P) covariance matrices. In many situations, blunders/faults in the measurement model and/or sudden changes in the dynamic model may occur during the navigation period. Therefore, the CKF, as well as the adaptive Kalman filter (AKF) will exhibit abnormal behavior and may lead the filter to be suboptimal or even diverge. In this study, the Sage-Husa adaptive Kalman filter (SHAKF) and innovation-based adaptive Kalman filter (IAKF) approaches are employed for adapting the measurement covariance matrix(R). In the case of abrupt changes in the dynamic model, the state covariance matrix (P) is adapted using the strong tracking filter (STF). The performance of these adaptive approaches is evaluated before and after simulating a fault of different sizes in the measurement and dynamic models. The results show that with a large window width, the SHAKF outperforms the CKF and IAKF. However, when the system encounters any fault either in the measurement or dynamic model, the SHAKF loses its optimality and diverges. The sensitivity of the SHAKF to the fault is because the R matrix accumulates with the propagation of the recursive noise estimator. On the other hand, the IAKF and STF provide better performance than both the CKF and SHAKF because the gain matrix is adaptively adjusted to mitigate the influence of the fault, and therefore, they behave normally when a fault of any size occurs in the measurement and/or dynamic model.
Nietzsche on Conflict and Agon
Authors: Tuncel Yunus
Published: March 2023

Agonism permeates Nietzsche’s spirit and works from early on starting with his close engagement with ancient Greece. However, while many thinkers have made references to agon in Nietzsche in the twentieth century, this aspect of his philosophy did not come under close scrutiny until a few decades ago, and some of the research in this area saw its first monographs in Tuncel’s Agon in Nietzsche (2013) and Acampora’s Contesting Nietzsche (2013). In addition to these two works and prior to them, an anthology, Nietzsche, Power and Politics, based on the proceedings of a conference and edited by Herman W. Siemens and Vasti Roodt, came out in 2008. The three editions reviewed here bring out many other aspects, insights, and nuances in the study of agon in Nietzsche’s works.
Analysis of bridge vibration response for identification of bridge damage using BP neural network
Authors: Wu Rui , Zhang Chong
Published: March 2023

In this article, the authors propose a method to identify the bridge damage using a backpropagation (BP) neural network. It uses bridge vibration response to solve the accuracy of bridge damage. A particle swarm optimization algorithm based on chaotic mutation is adopted to perform chaotic mutation operations and make the group jump out of the local optimum. CPSO (particle swarm optimization algorithm based on chaotic variation) algorithm can make up for the BP neural network model, easy to fall into the shortcomings of local optima, so the author will combine the two algorithms and discuss the environmental data of the bridge. Establishing a finite element model of the bridge through actual analysis, through data comparison, comparing the frequencies of the intact stages with the frequencies of the damaged stages, and verifying the neural network with random samples, for the degree of bridge damage, we get the root mean square error

m
s
e

mse

and the correlation coefficient r. The result shows that the root mean square error

m

e
=
0.003196

mse=0.003196

, and the correlation coefficient

r
=
0.9654

r=0.9654

. There are only a few individual points; it seems that the relative error is relatively large. The rest of the fit is basically the same; it can meet the factors of vibration through the environment and perform damage identification for the structural damage monitoring of the bridge. Using the BP neural network model optimized by chaotic particle swarms, combined with the modal analysis of environmental vibration, it can be used in the monitoring of the health structure of the bridge, plays a certain recognition effect, and provides a new technical idea.
Gastrofonia: a new cultural horizon of music and food
Authors: Scelzi Raffaella , Difino Nicola
Published: March 2023

The meaning of matter is determined by our interpretations. Even food has its own frequencies, which can be aligned with the specific notes of a musical scale. When presented with a dish we might ask not only “how does it taste?” but also “how does it sound?.” Gastrofonia is defined not as the musical accompaniment to a cooking demonstration, but the actual sound of it: music is made by food. Built upon an experiment initiated by John Cage to try to make music with objects, gastrofonia examines sound as a possible connection among the visual and material arts. Combining music with taste, musician Roy Paci identified a biosonic perception of food. This chapter aims to analyze the case of gastrofonia in light of the increased scientific and artistic interest in food characterizing our contemporary society, that is, an orthorexic society where food has become a specific form of language, a communicative vehicle through which we express our identity, interests, social-ethical choices, and new concepts of art. From a sociosemiotic perspective, the gastrofonic dish is an example of a textual polyphonic discourse combining different languages, related to the five senses in a performance that becomes a form of shared communication.

The dogs of Roman Vindolanda, Part I: Morphometric techniques useful in differentiating domestic and wild canids
Authors: Bennett Deb , Campbell Greg , Timm Robert M.
Published: March 2023

El fuerte-poblado romano de Vindolanda en el norte de Inglaterra fue ocupado desde el 50 al 415 A.D. y ha proporcionado una importante colección de restos bien conservados de perro, Canis familiaris. En este trabajo, utilizando una combinación inédita de técnicas bioestadísticas para determinar los parámetros que mejor diferencian cánidos, verificamos la hipótesis referida a una cría selectiva de perros por parte de los habitantes de Vindolanda. Al tiempo, discriminamos los restos de perros de los de lobo y zorro común, dos especies de cánidos de talla semejante al perro distribuidos por toda Eurasia. Los perros de Vindolanda se encuentran morfológicamente menos diferenciados que sus parientes actuales pero mucho más que sus parientes británicos del Neolítico y Edad del Hierro. Su diferenciación morfológica es igual de amplia que la de los perros procedentes de otros yacimientos romano-británicos y solo ligeramente inferior a la documentada para todos los perros de época romana procedentes de Europa y el Norte de África. Por ello, parece que los perros de Vindolanda sufrieron una selección direccional superior a la esperada cuando se asume sólo la existencia de presiones ambientales lo cual sugiere que fue una cría selectiva, y no tanto una panmixis aleatoria de individuos, lo que mantuvo tal grado de diversificación. Los perros de Vindolanda constituyen un grupo ideal para realizar análisis de ADN toda vez que parece incorporan individuos que manifiestan una diversificación incipiente a partir de antecesores con aspecto de dingo.

El yacimiento atrajo la atención debido a su tamaño y antigüedad así como por su localización en una región con escasas fuentes de agua perenne como lagos y ríos. Este informe refiere un análisis preliminar y, en gran medida descriptivo, de los restos faunísticos recuperados durante las primeras excavaciones llevadas a cabo entre 1978 y 1983. La muestra zooarqueológica proporciona información de base referida a antiguos patrones de aprovechamiento e intercambio de animales en El Mirador. Estos pueden así ser comparados con otros conjuntos faunísticos Preclásicos de las tierras bajas maya. Comparaciones diacrónicas dentro del yacimiento se infieren también de los usos animales en el bloque de la ocupación del Preclásico Tardío y un momento de menor entidad del yacimiento que se corresponde con el periodo Clásico.

To compare the properties of different plant fiber/soybean protein adhesive composites, six types of plant fibers (rice straw, wheat straw, peanut straw, rice husk, wheat husk, and peanut shell) were selected as reinforced materials, and soybean protein adhesive was used as the adhesive. Six types of different bio-composites were prepared by the compression molding process. The Fourier transform infrared (FTIR) spectra, mechanical properties, moisture absorption, and thermal stability of the composites were measured. The tensile cross-section microstructure of the composites was examined. Results showed that the peanut straw/soybean protein adhesive composite contained more hydrophilic groups. The wheat fiber-based composites possessed more hydrogen bonds, leading to the best binding interface compatibility and mechanical properties. The wheat straw/soybean protein adhesive composite had the highest tensile strength, flexural strength, and impact strength, which were 337.7%, 638.6%, and 483.4%, compared to those of the rice husk/soybean protein adhesive composite, respectively. The peanut shell/soybean protein adhesive composite’s equilibrium moisture content was the lowest (8.70%). The rice husk/soybean protein adhesive composite had the highest equilibrium moisture content (14.23%), and the best thermal stability as the initial temperature of pyrolysis was 283.4 °C and the residual mass was 34.45%.

The combustion resistance was investigated for dolomite, melamine (MEL), and ammonium polyphosphate used in the surface coating of particleboard. The surface coating materials consisted of a mixture of dolomite, melamine dust, ammonium polyphosphate, calcite, and water. The ratio of dolomite, melamine dust, and ammonium polyphosphate in the mixture was determined to be 10% based on the amount of calcite. The resulting mixture was applied to the surface of the particleboard at a thickness of 0.20 mm. Combustion tests were carried out according to ASTM E 69 standard. As a function of weight loss, the temperature values, amount of oxygen, amount of carbon dioxide, and nitrogen oxides of the test samples were determined. The results showed that the coating increased the combustion resistance of particleboard. Samples containing a 70% dolomite, 25% melamine dust, and 5% ammonium polyphosphate mixture or 100% dolomite produced the best results. The use of ammonium polyphosphate and dolomite positively affected combustion resistance.

Vermicompost produced from oil palm empty fruit bunch (EFB) was analysed to examine its thermal degradation and morphological appearance. The thermal degradation of vermicompost produced from untreated EFB and EFB treated with oyster mushrooms was characterised via thermogravimetric analysis (TGA) and differential thermogravimetric analysis (DTGA). It was observed that vermicomposting accelerated the thermal degradation of EFB and minimized the lignin content, but reduced lignin degradation of raw EFB. However, the thermal degradation of lignin increased in treated EFB vermicompost. The structural characterization of EFB vermicomposting revealed that the surface of the treated EFB was more fragmented than the untreated EFB vermicompost and raw EFB.

Published: March 2023

The diffusion properties of walnut (Juglans regia L.) and cherry (Prunus avium L.) wood perpendicular to the grain are presented. The wet and dry cup tests were carried out in normal climate conditions. Simultaneously, inverse analyses by means of the finite element (FE) method were conducted based on the experimental sorption data. The results show that the numerically derived diffusion model can predict the mass changes during the experiments with sufficient accuracy with a maximum global relative error of 0.43%. However, the numerically determined diffusion coefficients do not show an agreement with the experimental data.

Published: March 2023

Wood foam cores manufactured from Eucalyptus fiber/epoxy adhesive and 4,4′ oxybis(benzene sulfonyl hydrazide) (OBSH), ethyl acetate (EA), and microsphere polymer bead (Expancel®) as foaming agents were investigated. A 10 phr of OBSH showed superior properties of the 0.50 g/cm3 wood foam and that 0.70 g/cm3 was the optimal density. Also, 17 phr of EA loading gave rise to the better mechanical properties and was considered the optimal content. The microsphere polymer bead did not achieve significant expansion under the conditions employed. Manufacturing of single (X1) and double (X2) layer of lightweight sandwich structures engineered woods with teak/glass fiber-reinforced polymer (GFRP) skins was studied. The enhancement of the sandwich structures’ properties was mainly contributed by the core and also by the added thin interlaminated GFRP layer. In X1 and X2 sandwich structures, with the same volume fraction of core(s), marginal improvement occurred in the properties, caused by the addition of the thin inter-layer of GFRP. Small contributions of the core properties on the sandwich structures were also demonstrated. The sandwich structure derived from the OBSH core was superior in mechanical properties and heat distortion temperature (HDT). The sandwich structure made from EA was unsuccessful in achieving water resistance.
Hydration properties of briquetted wheat straw biomass feedstock

Biomass densification elevates the bulk density of the biomass, providing assistance in biomass handling, transportation, and storage. However, the density and the chemical/physical properties of the lignocellulosic biomass are affected. This study examined the changes introduced by a briquetting process with the aim of subsequent processing for 2nd generation bioethanol production. The hydration properties of the unprocessed and briquetted wheat straw were characterized for water absorption via low field nuclear magnetic resonance and sorption balance measurements. The water was absorbed more rapidly and was more constrained in the briquetted straw compared to the unprocessed straw, potentially due to the smaller fiber size and less intracellular air of the briquetted straw. However, for the unprocessed and briquetted wheat straw there was no difference between the hygroscopic sorption isotherms, which showed that the amount of cell wall water was not affected by the briquetting process and that the sugar yield was similar after a combined hydrothermal pretreatment and enzymatic hydrolysis. The factors which offset the benefits introduced by the briquetting process need to be further examined to optimize the processing parameters and enzyme recipe for better use of the wheat straw biomass feedstock.

The xylan recovered from alkaline black liquor (ABL) of oil palm frond (OPF) has the potential to be converted into value-added products that hold promise, especially for the pharmaceutical industry. This research highlights the maximum xylan relative recovery extracted from ABL by varying the extraction parameters such as the concentration of sodium hydroxide (NaOH) (2 to 10%) (w/v), reaction temperature (60 to 140 °C), and extraction time (30 to 150 min), followed by a 2-stage precipitation method. 6 M of hydrochloric acid (HCl) was used in the first stage to separate the lignin sub-fraction (LF) from the ABL, and 95% ethanol was used in the second stage to obtain xylan sub-fraction (XF). The optimal condition of 6% NaOH (w/v), 100 °C, and 60 min was able to recover 84% of xylan, with low contamination of lignin (7.7%) and glucan (0.3%) in XF, while higher contamination of lignin (19.3%) and glucan (10.9%) with lower amount of xylan (8.8%) were found in LF. The amount of lignin and glucan in LF through the first precipitation was higher than in XF from the second precipitation, leaving remaining fraction of XF mainly composed of xylan. In sum, the developed process reduced the alkali consumption while retaining a high xylan recovery under mild process conditions.

Statistical design and mathematical modeling were used to investigate the fed-batch enzymatic hydrolysis of steam-exploded sugarcane bagasse (195 °C, 7.5 min). First, a Box-Behnken experimental design was used to evaluate the effect of enzyme loading (8, 24, and 40 FPU g-1 glucans of Cellic CTec3®), stirring speed (100, 150, and 200 rpm), and substrate total solids (5, 12.5, and 20 wt%) on the release of glucose equivalents (GlcEq, mostly glucose) after hydrolysis for 48 h in batch mode. A simplified kinetic model was used to fit the experimental data, in which specific activities in Cellic CTec3 were not differentiated, enzyme adsorption was ignored, and end-product inhibition was only attributed to glucose accumulation. The adjusted kinetic model was used to predict the effects of substrate and enzyme intermittent feedings in fed-batch hydrolysis experiments. Compared with batch experiments at 20 wt%, the proposed fed-batch procedure was able to increase GlcEq productivity by nearly 68% using the same enzyme loading, producing substrate hydrolysates containing 91.8 g L-1 GlcEq.
