Biometric systems aim to reliably identify and authenticate an individual using physiological or behavioral characteristics. Traditional systems such as the use of access cards, passwords have shown limitations such as forgotten passwords, stolen cards, etc. As an alternative, biometric systems present themselves as efficient systems with a high reliability due to the physiological characteristics of each individual. This paper focuses on a deep learning method for fingerprint recognition. The described architecture uses a pre-processing phase in which grayscale images are represented on the RGB bands and then merged to obtain color images. On the obtained color images will be extracted the characteristics of the fingerprints textures.The fingerprint images after preprocessing are used in a deep convolution network system for decision making. The method is robust with an accuracy of over 99.43% and 99.53% with the respective variants densenet-201 and ResNet-50.

Published: September 2021

Understanding Indian cultural and ritual perspective of India has been important aspect of the sociologists and culturists. Perspective on Indian culture can be availed through understanding of Yagya as it is the basis of Indian culture. Survey by Nielsen Corporation has shown the proud feeling of Indians towards their culture while Wiber J Scott indicated that Indian students studying in America had gone to a level of ‘difficult situation’ towards understanding their culture and spirituality. Hence, the present study aimed to find understanding-level of youth (18-40 years) towards contemporary scenario of Yagya. The survey-questionnaire (self-prepared, Google form) was circulated through digital platforms. 566 participants had responded from the different disciplines and professions. 96.99% participants were aware of the term ‘Yagya’ or ‘Hawan’ and indicated it as important for health, environment, and spiritual development and for attaining peace of mind too, while 86.21% believed to have Yagya as part of daily life. The study has shown that youth were aware with the general and basic understanding of Yagya used in ceremonial purposes and surprisingly they (58.83%) also felt that it does not belong to one specific community or religion. However, there is also a category of youth (35.86%) that did not agree nor did that know about it (5.3%). It is also important to note that the questionnaire was circulated through social-media platforms and sharing of link was of personal interest, the majority of participants were familiar with Yagya, hence, such cross sectional study with wider population would justify the present research attempt.

Получены экспериментальные данные величин давления воды в порах асфальтобетонного покрытия в увлажненном состоянии под действием колес движущегося транспортного потока. Это позволило определить максимальные величины барического воздействия, глубину проникновения фронта давления жидкости и влияние его на разрушение покрытия. Выводы. Анализ полученных данных показал не только наличие хрупкого разрушения, но и наличие ударного воздействия движущейся в порах асфальтобетона влаги, превышающего его структурную прочность. С использованием экспериментальных данных получены регрессионные зависимости величины износа от стандартных параметров потока. Для эксплуатируемых покрытий регрессионная зависимость позволяет прогнозировать величину износа на весь жизненный цикл дороги.

Statement of the problem. The purpose of the study is to identify the effect of a wetted surfacing on its wear and tear. The mechanism of the effect of transport load in the presence of moisture and experimental methods of measuring its effect on the wear of the upper layer of asphalt concrete are discussed. Results. The contribution of the presence of moisture in the upper layer of the road surface to its wear and tear in the form of rutting is identified, and the hydrodynamic effect of water in the micropores of the surface is examined. Experimental data on the values of water pressure in the pores of an asphalt concrete pavement in a wet state under the action of the wheels of a moving traffic stream have been obtained. This made it possible to identify the maximum values of the pressure effect, the depth of penetration of the liquid pressure front and its influence on the destruction of a surfacing. Conclusions. Analysis of the obtained data showed not only the presence of brittle fracture, but also an impact effect of moisture moving in the pores of asphalt concrete exceeding its structural strength. Using the experimental data, regression dependences of the wear and tear value on the standard flow parameters were obtained. For the pavements in use, the regression dependence makes it possible to predict the amount of wear and tear for the entire life cycle of the road.

Authors:   Golinitskiy P.V. Leonov O.A. Shkaruba N.Zh. Antonova U.YU.
Published: September 2021

The study of the influence of the geometric parameters of the matrix on the quality of the process of reduction of bushings made of tin bronze is carried out. It is established, that for successful reduction plastic deformation should not exceed 10÷15 %, and the angle of the intake part of the crimping matrix should be within 25÷45°, a further increase in this angle significantly reduces the quality of the process. It is shown, that the angle of the lead-in part of the crimping matrix has an insignificant influence on the limiting compression ratio of the bushings, and an increase in the friction coefficient does not significantly affect the deformation parameters.

Two major disease and pest in oil palm are Ganoderma disease and bagworm infestation. Ganoderma disease caused by Ganoderma boninense and bagworm infestation caused by Metisa Plana has caused significant loss to oil palm industry. Therefore, early detection and control are important to reduce the losses. This paper reviewed the existing approaches, challenges and future trend of aerial remote sensing technology for Ganoderma disease and bagworm infestation in oil palm. The aerial remote sensing technology comprises of multispectral, hyperspectral camera and radar which have different platform such as satellite, aircraft and Unmanned Aerial Vehicle (UAV). The aerial multispectral and hyperspectral remote sensing analysed spectral signatures from visible and near infrared spectrum range for detection of the disease and pest attacks. Studies showed that satellite-based multispectral remote sensing only provide moderate accuracy (<70%) compared to UAV-based multispectral remote sensing (>80%) for detection of disease and pest infestation. Meanwhile, our study using UAV showed 90% of accuracy for moderate and severe Ganoderma disease detection in oil palm. Meanwhile, application of aerial hyperspectral remote sensing for Ganoderma disease showed potential for early detection of Ganoderma disease in oil palm and also can be used to detect early pest infestation in oil palm based on field spectroscopy results. Other than that, radar remote sensing has also able to differentiate healthy and Ganoderma-infected oil palm and also pest infestation by analysis of radar backscatter image of the foliar, frond and crown of oil palm. The challenges for the implementation of aerial remote sensing technology for disease and pest detection in oil palm is in tackling problems from shadows, mixed-class from single canopy and false-positive classification and also producing equipment at a lower and affordable price and also a user-friendly data analysis system that can be used by the plantations for a fast disease and pest detection works. The introduction of Artificial Intelligence (AI), Machine Deep Learning (MDL), low-cost remote sensing camera and light-weight UAV has opened the opportunity to tackle the challenges. As a conclusion, aerial remote sensing provides better and faster disease and pest infestation detection system compared to ground-based inspection. The advancement of the aerial remote sensing technology can provide more economic and efficient disease and pest infestation detection system for large oil palm plantation areas.

Authors: Eng Hui Yi , Mohd Rozalli Norazatul Hanim , Ilias Nurul Najihah
Published: September 2021

The rice bran oil (RBO) can form its semisolid spread through solvent fractionation. The rice bran oil spread (RBOS) is proposed to be included in the production of bakery products. The aim of this is study is to compare the physicochemical, textural properties and thermal properties of RBOS with commercial shortening (CS). Spreadability analysis was conducted using a texture analyzer. There was no significant difference (p > 0.05) in firmness and work of shear between CS and RBOS. The fatty acid compositions were determined through GC-MS. The major fatty acids in RBOS were palmitic acid, oleic acid and linoleic acid which is similar to those in RBO but significantly (p < 0.05) higher in saturated fatty acid content. RBO contains a high amount of γ-oryzanol and phytosterols which is beneficial in solid fat structuring. The quantitation of γ-oryzanol was performed by using UV-Vis spectrophotometer while the phytosterol content was analyzed by using HPLC. There was no significant difference (p > 0.05) in γ-oryzanol between RBO (1,299.88 ± 50.97 mg/ 100 g sample) and RBOS (1,201.86 ± 84.37 mg/ 100 g sample). However, there was a significant difference (p < 0.05) in phytosterols between CS (4.17 ± 0.26 mg/ 100 g sample), RBO (247.00 ± 0.89 mg/ 100 g sample) and RBOS (184.16 ± 0.56 mg/ 100 g sample).  Besides, thermal analysis of CS and RBOS were carried out using DSC and TGA. The similar textural properties but better physicochemical properties make RBOS becomes a suitable choice as alternate shortening for bakery product.

Published: September 2021

Spinal cord injury (SCI) is a traumatic injury leading to hypoxia, lipid peroxidation, and cellular apoptosis. Honeysuckle (Lonicera japonicae) has been used to treat headaches and play a neuroprotective role. However, its possible effects on protection from neurological function loss during injury remain to be explored. To this end, we have investigated the effects of honeysuckle extract on neural function injury in SCI rats and report an improvement in nerve function. The mechanism involved reduced expression of proinflammatory cytokines, decrease in cellular apoptosis, and activation of PI3K/Akt pathway. We conclude that possible use of honeysuckle extract for treatment of SCI needs further exploration.

Light-emitting diodes (LED) are widely employed in display applications and lighting systems. Further research on LED that incorporates carbon nanostructures and metal nanoparticles exhibiting surface plasmon resonance has demonstrated a significant improvement in device performance. These devices offer lower turn-on voltages, higher external quantum efficiencies, and luminance. De facto, plasmonic nanoparticles, such as Au and Ag have boosted the luminance of red, green, and blue emissions. When combined with carbon nanostructures they additionally offer new possibilities towards lightweight and flexible devices with better thermal management. This review surveys the diverse possibilities to combine various inorganic, organic, and carbon nanostructures along with plasmonic nanoparticles. Such combinations would allow an enhancement in the overall properties of LED.

Authors: Jaimes-Molina Víctor Manuel
Published: September 2021

La comunicación e interacción social son la razón de ser del uso de un idioma, por lo tanto, la enseñanza de lenguas debe privilegiar las habilidades relacionadas con la producción oral y la comprensión auditiva. Esta investigación contrasta la dificultad en la enseñanza y aprendizaje del inglés desde un enfoque comunicativo con el aprendizaje integrado de contenidos y lenguas (CLIL). Dicho contraste se dio por medio del diseño de una unidad didáctica de ciencias sociales, con el propósito de analizar la incidencia de CLIL en estudiantes de 12 a 14 años en la Institución José Odel Lizarazo. Para esto, el enfoque se llevó a cabo desde un paradigma cualitativo, proponiendo que la unidad didáctica partiera de la geografía local del departamento de Arauca y con las consideraciones del enfoque basado en tareas. El análisis se realizó por medio de la observación, notas de campo, registro audiovisual, cuestionario de entrada de salida, lo cual permitió comprender que un buen desempeño en la habilidad de “listening” propició la producción oral. Por otra parte, la integración de contenidos de ciencias sociales e inglés favoreció un aprendizaje activo en los estudiantes. Finalmente, el CLIL ofreció una alternativa a la necesidad lingüística de los estudiantes.

Published: September 2021

O presente artigo abordou a obsolescência programada como possível hipótese de prática abusiva. A partir da análise do arcabouço legislativo brasileiro e dos mais recentes julgados do Superior Tribunal de Justiça, concluiu-se que, além de inexistirem limites legais específicos para a obsolescência, a jurisprudência parece não distinguir quais os contornos entre a legalidade e a abusividade da conduta, não as entendendo como violações da legislação consumerista, mas também às políticas de proteção ao meio ambiente e ao que se pretende como desenvolvimento sustentável.
Collective Conviction
Authors: Eyre Anne , Dix Pam
Published: September 2021

This book tells the story of Disaster Action, a small charity founded in 1991 by survivors and bereaved people from the disasters of the late 1980s, including Zeebrugge, King's Cross, Clapham, Lockerbie, Hillsborough and the Marchioness. The aims were to create a health and safety culture in which disasters were less likely to occur and to support others affected by similar events. The founders could not have anticipated the degree to which they would influence emergency planning and management and the way people are treated after disasters. Aware of the value of lessons learned over 22 years, the trustees felt that this corporate memory should be captured. The book encapsulates that memory, so that it can be called upon by survivors, the bereaved, governments and others for years to come. The book sets out the chronology of Disaster Action's history, with first-person accounts and case studies of disasters interweaved with chapters on the needs and rights of individuals, the treatment of bereaved and survivors, inquests and inquiries, the law, the media, memorials and commemorations, and the importance of corporate memory. Additionally, it contains guidance notes for survivors and bereaved on dealing with a disaster, and best practice guidance for responders and the media. This book is essential reading for those in a wide range of disciplines with an interest in planning for, responding to, reporting on and dealing with the aftermath of disaster. And importantly, people affected by disaster should find solace and support in the personal stories of others.

This introductory chapter recounts the experience of the author joining Disaster Action in 1996, six years after surviving the Hillsborough football stadium disaster. Since joining, the author has taken an active role in Disaster Action and seen its core values and messages become more embedded within emergency management as the field has become more professional. With the approach of the 20th anniversary of the disasters that led to its inception, new members were still joining the organisation from different tragedies. Disaster Action was evolving in response to a rapidly changing world and developing context of emergency planning and management. While preventing future disasters from happening has been one of the building blocks underpinning the organisation's aims from the outset, it is important to note that absolute safety and security are impossible to achieve. Yet those charged with corporate governance in companies and organisations large and small should be enabled through the experiences of survivors and bereaved people to appreciate the significance of their responsibility, from an ethical as well as legal standpoint.
Decade of Disaster – How It All Began
Authors: Eyre Anne , Dix Pam
Published: September 2021

This chapter traces the origins of Disaster Action, which lie in the personal experiences of individuals. A number of disasters occurred between 1985 and 1989, each involving many deaths and injuries — physical and psychological — within relatively quick succession. After each major disaster of the 1980s, relatives, friends, and survivors formed support groups to help those directly affected. The questions of how and why people had died and been injured and how similar disasters might be prevented in the future drove those from different backgrounds, of all religious persuasions and none, to come together. Each group had its own focus — for Zeebrugge, ro-ro ferry safety; for Lockerbie, airline and airport security; for the Marchioness, a full inquest and riverboat safety. These groups worked tirelessly to cope with and campaign on issues relating to their own tragic circumstances, lobbying government and other interest groups. The chapter then details how the disparate individuals and groups affected by this series of preventable tragedies in the 1980s come together to form the umbrella association that was to be Disaster Action. Ultimately, Disaster Action was established out of a collective will to see a more just and safer Britain.
Communicating the Messages
Authors: Eyre Anne , Dix Pam
Published: September 2021

This chapter details how, in the months leading up to the formal launch of Disaster Action, members were invited to contribute to numerous conferences, seminars, training events, and exercises. They found themselves sharing platforms with lawyers, civil servants, business leaders, and police officers. At those early events there was much emphasis on disaster management, corporate responsibility, and the litigation that inevitably follows in the wake of disaster, involvement in which had added so much to the distress of those on the receiving end. Although every speaker for Disaster Action uses their own experience as the basis for a presentation, key universal messages remain the same, including the point that good lines of communication with relatives and survivors are essential. As the world of emergency planning and management began to reflect on the needs of people, awareness grew of the important role and positive contribution Disaster Action could make in humanising policies and procedures. The chapter then looks at how Disaster Action produced a series of leaflets for survivors and bereaved people; developed information and advice for policy makers and practitioners; and provided telephone support.
Inquests, Inquiries and Investigations
Authors: Eyre Anne , Dix Pam
Published: September 2021

This chapter addresses how, for many survivor and family support groups, the quest for information and accountability often became legitimately focused on the responding authorities and the way in which they conducted their affairs before, during, and after the disasters occurred. Each disaster had resulted in a series of inquests, inquiries, and investigations, many of which remained ongoing for years, yet still leaving untold the full story of what had happened. While such inquiries are necessary in order to conduct a thorough and comprehensive review of what happened, the timeframe, bureaucracy, arbitrary conduct, and discretionary nature of decisions and procedures contributed to and prolonged the emotional trauma. Indeed, the ups and downs of ongoing legal battles would leave many people feeling as victimised by, and as angry at, the systems of inquest and inquiry as they were at the fact of the deaths themselves. In the long run, this led Disaster Action members to focus not only on resolving their own disasters but on campaigning for, and contributing to, broader changes within the often antiquated and highly politicised systems of inquest and investigations themselves.
Challenge and Conformity
Authors: Taylor-Guthartz Lindsey
Published: September 2021

Orthodox Jewish women are increasingly seeking new ways to express themselves religiously, and important changes have occurred in consequence in their self-definition and the part they play in the religious life of their communities. Drawing on surveys and interviews across different Orthodox groups in London, as well as on the author's own experience of active participation over many years, this is a study that analyses its findings in the context of related developments in Israel and the USA. Sympathetic attention is given to women's creativity and sophistication as they struggle to develop new modes of expression that will let their voices be heard; at the same time, the inevitable points of conflict with the male-dominated religious establishment are examined and explained. There is a focus, too, on the impact of innovations in ritual: these include not only the creation of women-only spaces and women's participation in public practices traditionally reserved for men, but also new personal practices often acquired on study visits to Israel which are replacing traditions learned from family members. The book is a study of how new norms of lived religion have emerged in London, influenced by both the rise of feminism and the backlash against it, and also by women's new understanding of their religious roles.
Setting the Scene: The Jewish Landscape
Authors: Taylor-Guthartz Lindsey
Published: September 2021

This chapter examines the historical and sociological context of Orthodox Jewish women in London, and applies concepts of community to analyse the religious geography of Orthodox Jews in Britain. The term 'community' is used by British Jews, generally in one of two distinct senses: the first, refers to all Jews who identify as Jews and participate in Jewish activities, the second, indicates a particular subgroup, the members of a particular synagogue. Most Jews who identify as belonging to the Jewish community also belong to several of these 'subcommunities,' all of which overlap with family and social circles within the Jewish and wider communities, and most of which are not mutually exclusive. Community affiliation thus exists at several levels and in several modes, with an individual's particular combination of networks and community memberships providing basic parameters of his or her individual Jewish identity. This complex, layered character of modern Jewish identity complicates the definition of the term 'Orthodox'. Current denominations include Liberal Judaism and Reform Judaism; Masorti Judaism; and Orthodox Judaism. Earlier tensions between traditional expectations for women and new ideas about their role in the wider society were reflected in developments within the British Jewish community: the foundation of Liberal Judaism. Orthodoxy has been slow to respond. The very word 'feminist' carries negative connotations in most Orthodox communities, even among women who profess strongly feminist views in economic and political matters.
Before and After the Eighteenth Century: The John Blanke Project
Authors: Ohajuru Michael
Published: September 2021

This chapter, authored by Michael Ohajuru, describes the origins and mission of the John Blanke Project of which he is the creator. John Blanke was a black trumpeter for the Tudor Court, pictured twice in the Great Tournament Roll of Westminster, and the first person of African descent in Britain for whom there is an identifiable image and documentation. Because so little is known of Blanke’s life, the Project commissions artists to portray Blanke in a variety of artistic mediums including poetry, rap, music, visual arts and the stage, letting history inform their imaginations. The Project also invites historians to contribute written pieces to add dimension to an understanding of what Blanke’s life might have been like in this time and place. The chapter attributes the genesis of the project to presentations Ohajuru gave with Dr Miranda Kauffman entitled Image and Reality: Black Africans in Renaissance England (IRBARE) in which he discussed images of the black magus or black king in art and the inclusion of Blanke in commissioned paintings by Stephen B. Whately on the life and times of Henry VII.
Britain’s Black Tars
Authors: Foy Charles R.
Published: September 2021

In this chapter, Charles R. Foy discusses the critical role black mariners played in maintaining the strength of the 18th century British Empire through employment with the Royal Navy and merchant ships as well as examines the risks and rewards that life on the sea entailed for these men. Foy outlines three significant paradoxes in the lives of these black tars. First, while a shortage of white seamen provided job opportunities for blacks, many of whom were fugitive slaves from the Americas, others were compelled to work at sea by slave masters, press gangs or Admiralty Court judges. Secondly, black mariners had few protections from being sold or captured while at sea so escaping the grasp of slavery for fugitives was far from certain. Finally, while the Black Mariner Database that Foy created shows that communities of black seamen developed in Britain’s larger ports, he explains that few had local family, there was a paucity of black women to partner with and they lacked the connections to establish social and economic independence.
The Georgian Life and Modern Afterlife of Dido Elizabeth Belle
Authors: Gerzina Gretchen H.
Published: September 2021

Written by Gretchen H. Gerzina, this chapter examines research into the life of Dido Elizabeth Belle and probes the resurgence of interest in her story as the subject of film and television projects. Born to an African woman, Maria Belle, and British naval officer Sir John Lindsay, Gerzina describes how Dido’s legal status has often been misunderstood and misrepresented, yet modern research has made it clear that she was never a slave and was born free in London. As the grand niece of William Murray, the first earl of Mansfield, Dido spent much of her life comfortably as part of his household at Kenwood House in London before marrying a white Frenchman. During her years at Kenwood House, she was the subject of a double portrait with her cousin Elizabeth Murray that Gerzina explains has played a large role in sparking the modern imagination about what her life was like as a mixed-race member of elite British society.
