Kunnskapsformer og danningsidealer i lærerutdanningen
Authors: Moen Elin Tronsaune , Page Alexander Gamst
Published: April 2020

The Norwegian national guidelines for primary school teacher education grades 5–10 state that “all subjects in the education must be included in a formation process that ensures that the student possesses the ability to see a case from different sides and research the professional practice from different perspectives” (Kunnskapsdepartementet, 2016, s. 8).
This study is based on interviews with elementary school preservice teachers. The focus is on their experiences related to the development of their roles as teachers vis-á-vis the place of study and the field of practice. Through conversations with the students, the experience they have of “to do” the teaching profession, “to understand” and / or “to be” the teaching profession is particularly emphasized. These experiences are put into different contexts by the students. Common to all of them is that they are linked to different understandings of knowledge, and not least are the experiences linked to factors that in the theory are emphasized as important when talking about formation and professional development.
In order to elucidate the complexity of their experience, we will discuss their reflections and understandings in light of the formation ideals and knowledge forms. Such an approach to discussing the student’s reflections and experiences will also reveal something about the connection between guidelines and the mission of education formation. In this context, it may be possible to say something about the need for a more conscious approach to the educational institutions’ commitment to the students, particularly regarding the knowledges and skills that are part of their professional development.
La experiencia de estudiar sexualidades en contextos escolares. Un ejercicio de reflexividad epistemológica, ética y afectiva para una etnografía feminista
Authors: Romero Guillermo
Published: April 2020

El trabajo busca sistematizar algunos de los principales aportes que una perspectiva feminista puede brindar a los estudios etnográficos de procesos educativos. Toma como principal insumo las investigaciones realizadas sobre la experiencia escolar en su dimensión sexuada entre 2011 y 2019 en escuelas secundarias de la ciudad de La Plata, Argentina, en el marco de la implementación de la Educación Sexual Integral. El artículo pretende demostrar que, si bien no resuelve algunas de las tensiones inherentes a la teoría social, poner en primer plano la dimensión afectiva del trabajo académico constituye una herramienta sustancial no sólo en su performatividad ético-política para los procesos estudiados, sino también como insumo estratégico en la construcción del conocimiento científico.
Surrealism Between Psychological Investigation And Artistic Commitment
Authors: GIULIODORI Lucio , BOLDYREVA Aisana , BOBUNOVA Anna , BORANENKOV Vladislav
Published: April 2020

Deciphering the mysteries of the unconscious was one of the central aims of Surrealists who, in order to achieve this goal, experimented with the most different techniques. The unconscious, displaying the contents that then can be painted, turned to be both a way to embark on an inner exploration and a source of creativity.

My paper firstly sheds light onto this marriage of art and psychology which, in Surrealism, harmoniously blended generating a fascinating and fruitful combination between creation and self-creation - art as a tool of self-knowledge and even inner evolution is one of the main consequences.

Lastly this study examines the surrealist scene today, considering how and why, through the decades, the painters’ aims changed and why we should or shouldn’t still call them “Surrealists”.
On The Perceptual, The Conceptual, The Objectively Real And The Problem Of Truth In Cosmogony And Cosmology
Authors: OGORODNIKOV Vladimir , OGANYAN Kadzhik
Published: April 2020

Данная статья посвящена философским основаниям различных объяснений фактов, известных из последних научных достижений космогонии и космологии. Показано, что некоторые объяснения по рассматриваемому вопросу молчаливо реабилитируют идею антропоцентризма, уходящую своими корнями в теорию Птолемея. В этом контексте большое внимание уделяется критическому анализу антропного принципа, который является одной из версий современной телеологии. Предполагается, что вышеупомянутый принцип основан на неадекватной интерпретации гипотезы Большого Взрыва. При этом антропный принцип определяется с одной стороны аристотелевской теорией телоса, а с другой-религиозными и мистическими идеями сотворения мира и человечества. В противоположность этому, многомировая интерпретация или интерпретация Эверетта приравнивает концептуальную и объективную реальность, идущую на этом основании в другую крайность и постулирующую почти бесконечное множество альтернативных вселенных.

В данной статье освещаются вопросы, характерные для философско-методологических оснований заблуждений и критериев познания истины в космогонии и космологии.
Communication Noise as a Discourse Component
Authors: OLIINYK Ganna , BIGUNOVA Natalia , SELIVANOVA Olena
Published: April 2020

The paper focuses on the investigation of communicative noise at various levels of monocultural and intercultural communication. Communication noise is seen as a component of a communicative event, functioning as obstacles of different nature that lower the effectiveness of communication, destabilize it and are able to cause communicative conflict or the breakdown of communication. In linguistic pragmatics the main features of communication noise have been identified as vagueness and ambiguity of a message: vagueness is characterized by a bigger degree of noise than ambiguity. The authors of the article have tried to probe more deeply into the area of communication noise by singling out levels of communicative situation. The article offers a differentiation of five discourse levels: verbal-semiotic, cognitive-interpretational, interactive, ontological and sociocultural levels. The main part of the paper analyzes the barriers that cause communication noise at each of the offered levels of communicative situation. The raised issues offer prospects for further research, such as investigating of noise effects in real communication, identifying a set of causes leading to communication noise, as well as noise-resistant factors, preventing or removing it.
From Hunter to Protector: The Invention and Reinvention of the Nuri Talaud
Authors: Batiran Karno , Fisher Micah
Published: April 2020

This article describes the ways in which the Nuri Talaud, a small colorful bird located on an island at the northern reaches of Indonesia, first became a hunted commodity and evolved into a thriving protected species. Told from the life history of Om Zaka, a local hunter turned bird conservationist, this article describes the background that shaped the shifting values placed on the Nuri Talaud. The bird initially gained value as a symbol of the state through its selection for inclusion in Indonesia’s national theme park. As a result of its newfound prominence, local hunters emerged to systematically hunt the bird for sale through a network of international species trade. Nearly facing extinction, various actors and initiatives came together to protect the Nuri Talaud. This paper shows the ways in which a species can be targeted to almost extinction, and the processes that can take shape to ensure its protection.
Protecting the Mbau Komodo in Riung, Flores: Local Adat, National Conservation and Ecotourism Developments
Authors: Asriyani Halia , Verheijen Bart
Published: April 2020

The Komodo dragon is one of the most exotic animals of the Wallacea region. Conservation efforts aimed at protecting the Komodo dragon and the unique biodiversity in the region have created a particularly strained relationship between state interests, local livelihood and tourism developments. This article examines recent antagonisms between national agencies, local interests and livelihoods by describing a unique and relatively unknown case study: the Riung Subdistrict and Sambinasi Village and the protection of the Komodo dragons by the local Baar community. Based on information from 19 qualitative in-depth interviews, and the analysis of a recent local Adat meeting in March 2019, this article shows that the Baar were successful in reclaiming land from the national conservation agencies. Meanwhile, they simultaneously formulated new local customary rules on how to treat the Komodo dragon, hence reclaiming ownership over conservation rules and empowering local institutions. Recently, all parties have subscribed to a new ecotourism agenda for further development of the area. This agenda might reshape relations between national agencies and the local communities, as conservation is increasingly linked to new forces of global tourism.
Social Contracts: Pillars of Community Conservation Partnerships in Lore Lindu National Park, Indonesia
Authors: Anugrahsari Ice , Sardjono Mustofa Agung , Fitriyah Nur , Golar Golar
Published: April 2020

The Community Conservation Partnership Agreement (KKM) was an effort to reduce, prevent and mitigate the impacts arising from the complexity of managing Lore Lindu National Park. Several approaches in building KKM in the National Park had been carried out by several parties but had not proceeded as expected. Social Contracts were built to advance community agreements. The purpose of this study was to explore the obstacles and strategies for implementing KKM in the National Park. A qualitative approach was used in this study, through in-depth interviews, field observations, and active research in the process of drafting the KKM agreement. The results showed there were multiple interpretations of the roles, functions, and work of the parties based on their authority and interests in building the KKM. This resulted in the KKM becoming unsustainable. Findings show that in order to re-establish the KKM requires strategic steps, which mediate across stakeholder interests. Partnerships towards effective social contracts would only succeed if there was recognition of, and meaningful involvement among parties that begin at the design and planning processes and continue throughout the implementation phases of the partnership activities. The process of building a social contract must therefore begin with solid communication between stakeholders, which establish institutional mechanisms that are systematic, promote active coordinative, and are based on the trust and understanding between stakeholders.
Patterns and Trends of Crocodile Trade from Tanah Papua, Indonesia
Authors: Untari Dewi , Hardjanto Hardjanto , Nugroho Bramasto , Soekmadi Rinekso
Published: April 2020

Crocodylus porosus and C. novaeguineae are two protected and tradable crocodile species in Indonesia. Therefore, precautionary principles are needed in their utilization to ensure sustainability. Although the commodity from these species is traded domestically and internationally, the broader picture of its use in Indonesia is less known. The objectives of the study were to: (1) analyze the domestic trade of crocodiles, and (2) analyze the international trade of crocodiles. The analysis was conducted using data of direct utilization sourced from the wild in the form of skin and hatchlings, data on domestic transport permits, CITES export permits, and the CITES trade database. The study suggested that the harvest of crocodile hatchlings and skin do not represent the actual condition since the skin recorded were only those sent outside of the province. Determining zero harvest quotas of C. porosus did not stop species harvest for domestic trade. The dominant source of C. porosus skin export was captive breeding, while C. novaeguineaewas sourced from the wild. Ranch-sourced skin of both species for export were very low.
Seedling Recruitment of Native Tree Species in Active Restoration Forest
Authors: Ratanapongsai Yingluck
Published: April 2020

Since 1970’s, large are of deforestation and forest conversion to agriculture in the northern mountains of Thailand grew concern of environmental impact. Forest restoration became an important strategy to rapidly increase forest habitat in a wide-scale in Thailand. The Framework Species (FWS) technique is an active forest restoration that has been developed to restored forest habitat and ecosystem on former-agriculture land in the northern Thailand. After planting 20-30 framework species, the method then relies on incoming native tree species to sustain forest succession. However, there has been little known about the recruitment of native tree species and factors limiting the recruitment in this area. The study compared recruit native tree species in the seedling community of the FWS restoration and nearby seed source to assess how many of those are recruit or absent from the community. The factor of seed-dispersed agents and seed sized was investigated as the possible limited factors of the recruitment and compared among 3 restoration periods (at age 6, 10, and 14 years). The result reveals half of native species were absent from the seedling community across all 3 restoration ages. Seed available was a major limitation for the recruitment of native tree species. Big-seeded species had higher chance to be limited than small-seeded species to recruit in the restoration site (p-value = 0.0249 by the Tukey test). whilst seed-dispersed agents were not limited (p-values=0.420 by Chi square). The FWS forests efficiently facilitated seedlings of native tree species to recruit at the similar recruitment rates across all 3 ages of restoration. However, the technique was still limited in regard of seed available. Species of less common or rarer might need to be included for the FWS plantation in the future to enhance species diversity and better outcome of the restoration.
The knowledge and opinions of prospective elementary school science teachers in Turkey regarding renewable energy
Authors: KARA Filiz
Published: April 2020

In this research, it is aimed to determine the knowledge and opinions regarding renewable energy of 64 prospective teachers. The study data were collected by using a questionnaire consisting of 12 open-ended questions and analyzed using the descriptive analysis method. The study results showed that prospective teachers were generally of the opinion that renewable energy sources are mainly used by developed countries. In addition, most of the prospective teachers thought that media organs and scientific meetings and schools should be utilized as platforms for increasing social awareness of renewable energy sources. However, it was also determined that the number of prospective teachers who learned about renewable energy sources from their parents was considerably limited.

Dharma sprzed abhidharmy
Authors: Kosior Krzysztof
Published: April 2020

Dharma before the Abhidharma: The paper deals with the issue as to whether early Buddhism can be defined as a philosophy or as a religion. My analysis starts with the definition of the Buddha as the discoverer of the Dharma — the ancient and ennobling path (purāṇa‑, ariya‑magga) — which has made him the exalted teacher of gods and people. Then, after characterizing the possible meanings of Abhidharma in the context of their presence in canonical statements expressing Dharma, I draw conclusions about the connection or lack of connection between philosophy and soteriology in the teaching of the Buddha. Finally, after recalling the canonical statements of Buddha on his status, I conclude that the characterization of early Buddhism as a religion is also questionable.
Philosophia fundamentalis Friedricha Adolfa Trendelenburga
Authors: Hanuszkiewicz Wojciech
Published: April 2020

Friedrich Adolf Trendelenburg’s philosophia fundamentalis: Friedrich Adolf Trendelenburg (1802–1872) is an author who connects two periods. On the one hand, he attended the lectures of one of the first followers of Immanuel Kant — Karl Leonhard Reinhold, he knew personally

and was influenced by Georg Wilhelm Friedrich Hegel and Friedrich Wilhelm Joseph von Schelling. On the other hand, Trendelenburg has educated a very large group of important figures within the German philosophy of the late nineteenth and early twentieth century (e.g., Wilhelm Dilthey, Franz Brentano and Hermann Cohen). His main work, Logische Untersuchungen (Logical investigations), was to see its release in three editions during his life. In the second edition Trendelenburg adds an introductory chapter, entitled Logik und Metaphysik als grundlegende Wissenschaft [Logic and metaphysics as a basic science]. It presents the idea of philosophy as a science and, like a lens, focuses on the most influential metaphilosophical solutions of the second half of the nineteenth century. The article in its first part presents the academic biography of Trendelenburg, while in the second it discusses the most important meta‑philosophical problems raised in Logische Untersuchungen.

Authors: Çağlayan Nuri , Uçar Esra , Ertekin Can
Published: April 2020

The aim of this study was to examine the effect of five different wavelengths of light on the comfrey plant (Symphytum officinale) (family Boraginaceae). The light source and wavelengths used in the study were UV-A (390-410 nm), blue (465-485 nm), red (620-630 nm) and cool white (CW) daylight (400-700 nm, 6500 K), LED (Light Emitting Diode). In the study, each of the 5 different light applications was applied for 45 days (T1: 100% blue; T2: 100% red; T3: 60% blue + 35% red + 5% UV-A; T4: 100% CW daylight; T5: 80% CW + 20% red). The experiments were carried out under conditions of 22ï‚°C temperature, 60% humidity, 16/8 hours light/dark and 180 Âµmol.m-2.s-1 Photosynthetically Active Radiation (PAR). After each application, measurements were taken of number of leaves, number of roots, height of plant, amount of chlorophyll in leaves, leaf colour and brightness. According to data obtained, the different wavelengths of the coloured light applied in the growing environment created a change in colour and brightness of the leaves, height of the plant, length of the roots, and number of leaves and roots.

Published: April 2020

Bu araştırma, farklı azot kaynakları ile yapılan ilave yaprak gübrelemesinin marul (Lactuca sativa L.)‘da verim ve nitrat birikimi üzerine etkisini belirlemek amacı ile tarla koşullarında yürütülmüştür. Bitkisel materyal olarak bir adet yaz sıcaklarına dayanıklı kıvırcık marul (cv. ‘Bohemia F1‘) çeşidi, yaprak uygulaması olarak da üre (CO(NH2)2), potasyum nitrat (KNO3) ve kalsiyum nitrat (Ca(NO3)2)‘ın %0,4, %0,6 ve %0,8‘lik dozları kullanılarak yaprak gübrelemesi yapılmıştır. Yaprakta toplam azot değerleri %2,20 (KNO3 %0.4) ile %3,00 (Üre %0,8) arasında değişmiştir. En yüksek nitrat birikimi 2610 mg kg-1 ile Ca(NO3)2‘ın %0,8‘lik uygulamasında belirlenirken, en düşük nitrat birikimi ise 2070 mg kg-1 ile sadece taban gübrelemesi (NH4NO3) yapılan parselde tespit edilmiştir. Farklı azot kaynakları ile yapılan ilave yaprak gübrelemesi sonucunda marulda en yüksek verim değerleri sırasıyla 4926 kg da-1 (Üre %0,6), 4787 kg da-1 (Üre %0,8) ve 4719 kg da-1 (Ca(NO3)2 %0,6) olarak tespit edilmiştir. Ancak, diğer girdilerin eşit olduğu araştırmada; gübre masraflarını dikkate alındığında karlılık analizinde ilk üç sıra diğer gübrelere göre düşük maliyetinden dolayı, ürenin farklı dozları ile yapılan ilave yaprak gübrelemesinde tespit edilmiştir. Araştırma sonuçlarına göre; karlılık oranları da göz önüne alındığında üre (%0,6) ile yapılan uygulamaların hem yüksek verim hem de yüksek kar elde etmek için daha uygun ve önerilebilir ilave yaprak gübrelemesi olduğu açık bir şekilde söylenebilir.

Indonesia merupakan salah satu negara rawan gempa di dunia. Untuk mengurangi dampak akibat gempa khususnya jatuhnya korban jiwa akibat keruntuhan bangunan, maka dalam perencanaan struktur gedung di daerah rawan gempa, perilaku atau kinerja gedung terhadap gempa merupakan salah satu hal terpenting untuk diperhatikan. Oleh karena itu, perhitungan analisa secara inelastik atau nonlinier harus dilakukan. Beberapa metode untuk perhitungan analisis nonlinier meliputi analisis beban dorong (static nonlinear pushover analysis) dan analisis riwayat waktu (inelastic dynamic time history analysis). Penelitian ini membandingkan hasil kinerja dari analisis beban dorong dan analisis riwayat waktu dengan menggunakan rekaman gempa San Fernando, Morgan Hill dan Kobe untuk gedung beton bertulang SRPMK 6 lantai.

Dari hasil analisis beban dorong maupun analisis riwayat waktu, didapatkan tingkat kinerja yang sama yaitu kategori IO ( Immediate Occupancy ) baik untuk arah X dan Y. Target displacement yang didapat dari analisa beban dorong sebesar 0,092 m untuk arah X dan 0,096 m untuk arah Y. Sedangkan displacement maksimum yang didapat dari hasil analisa riwayat waktu adalah sebesar 0,0129 m untuk arah X dan 0,005 m untuk arah Y yang berasal dari rekaman gempa Kobe dan gempa San Fernando.

Published: April 2020

Research subject. This article considers accessory minerals, which, unlike zircons, are present in the vast majority of common clastic rocks. Materials and methods. The data on the chemical composition of minerals (garnet, tourmaline, chromespinelide, rutile, chloritoid and clinopyroxene) extracted from the Riphean and Vendian, as well as Upper Permian and Lower Triassic sandstones of the Southern Urals, were used to illustrate the features of applying various methods and techniques. In addition, numerous examples from publications are presented. Results. A number of modern methods for studying accessory minerals, which might be used to elucidate the composition and characteristics of the provenance rocks for terrigenous strata, were reviewed. Conclusions. It is shown that, similar to zircons, accessory minerals possess a significant potential in terms of providing important data on parent rocks.
Mineralogical and geochemical features of the black shales surrounding the Kara Astrobleme (Pay-Khoy)
Authors: Kovalchuk N. S. , Shumilova T. G.
Published: April 2020

Research subject. The Late Paleozoic (D3–P1) black shale strata surrounding the Kara Astrobleme (Pay-Khoy) were studied. Materials and methods. The rocks were sampled radially along the profile from the edge of the astrobleme (the at the contact zone with impactites) with access to black shales that were not affected by post-impact transformations. An analysis of the mineralogical and geochemical features of the black shales surrounding the Kara astrobleme was carried out using a complex of modern research methods (Geonauka Centre for Collective Use, IG FRC Komi Scientific Centre, Ural Branch of the Russian Academy of Sciences) in order to identify the possible mobilisation, re-deposition and concentration of ore matter under the conditions of intensive post-impact hydrothermal altering. Results and conclusions. The geochemical features of the black shale deposits altered by post-impact hydrothermal processes in the vicinity of the Kara impact structure were determined. The sharp abnormal contents of Mn, B, Zr, Sr, Ge, Cd, Hf, Se and Eu as well as the abnormal contents of Ti, Ba, Cr, Rb, Li, Ce, La, Ga, Sc, Co, Cs, Gd, Dy and W were revealed. The geochemical concentration specificity of components in different regions of the Kara astrobleme associated with the specialisation of target rocks was established. Raremetal and rare-earth minerals, sulphides and thymannite (HgSe) were diagnosed.
The first results of isotopic (U-Pb, ID-TIMS) dating of individual zircon grains from dolerite dikes of the Eastern zone of the Urals
Authors: Smirnov V. N. , Ivanov K. S. , Bayanova T. V.
Published: April 2020

Research subject. The article presents the results of dating two dolerite dikes differing in geochemical features from a section along the Iset river in the area of Smolinskoe settlement (the Eastern zone of the Middle Urals). Materials and methods. The dating was performed by an U-Pb ID-TIMS technique for single zircon grains using an artificial 205Pb/235U tracer in the laboratory of geochronology and isotope geochemistry of the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences. The lead isotopic composition and uranium and lead concentrations were measured using a Finnigan-MAT (RPQ) seven-channel mass spectrometer in dynamic mode using a secondary electron multiplier and RPQ quadrupole in ion counting mode. Results. The dikes were dated 330 ± 3 Ma and 240 ± 2 Ma. Conclusions. The research results indicate different ages of dolerite dikes developed within the Eastern zone of the Middle Urals. The oldest of the two established age levels corresponds to the Early Carboniferous era. This fact, along with the proximity of the dolerites to the petrochemical features of the basaltoids of the Early Carboniferous Beklenischevsky volcanic complex, allows these bodies to be considered as hypabyssal comagmates of these volcanics. The youngest obtained age level – Triassic – indicates that the introduction of some dolerite dikes was associated with the final phases of the trapp formation developed rarely within the eastern outskirts of the Urals and widely further east in the foundation (pre-Jurassic basement) of the West-Siberian Plate.

Subject. The aim of the work is to study the mechanism and sources of water formation, as well as the peculiarities of carbonate mineralization in the aquifer of the Kyndyg thermal water deposit. Materials and methods. The samples of water (8) and deposited carbonates (15), collected at different seasons at three sites, characterized by different temperatures and distances from the source, were investigated. pH, Eh, and electrical conductivity were determined by an electrochemical method. For the determination of HCO3 – , Cl– , SO4 2–, titrimetric, mercurymetric and turbidimetric methods were used. Trace element composition was determined by ICP-MS (NexION 300S); strontium isotopic composition – by MC-ICP-MS (Neptune Plus) using the bracketing technique after Sr chromatographic separation. Results. The chloride-calcium hydrochemical type prevails in the studied waters. A number of trace elements in water exceeds the clarke concentrations for groundwater in the supergene zone of mountain landscapes. 87Sr/86Sr isotope ratios (0.7065–0.7072) in thermal waters suggest that their composition is determined rather by the isotopic characteristics of the rocks through which water drains than by the influence of sea water. Among the newly formed carbonates, aragonite prevails. In contrast to thermal water, the concentrations of most metals in carbonates are below the clarke values; only Sr and Se are increased, which content is significantly increased in water as well. Deposited carbonates are characterized by 87Sr/86Sr values (0.7028–0.7074), which are lower than in the source thermal waters. Conclusions. On the basis of hydrogeological, hydrochemical and geochemical data, it can be assumed that the waters of this aquifer complex are formed mainly due to fresh fractured karst waters of lower Cretaceous limestones with submerged monocline dipping into the zone of slow circulation and mixing with sedimentogenic sodium chloride waters. The geochemical data and the presence of scandium anomaly suggest that the underlying Jurassic volcanogenic rocks also participate in water exchange.

Authors: Fadhil Abed1 Mahmood , Ahmed2 Salwa Hadi
Published: April 2020

This research has investigated the quality of surface water at Baiji district of Salah Alden governorate based on 5 sampling stations for two season (September 2012 and April 2013). Water evaluation indices (i.e. heavy metal pollution index (HPI), heavy metal evaluation index (HEI) and contamination degree index (Cd)) are utilized to characterize the quality of water in term of drinking purposes. All values of HPI were lower than (15), suggesting low heavy metal pollution. The values of HEI were also less than (10), indicating low heavy metal pollution, whereas Cd values were much less than (1) for all stations, indicating low heavy metal pollution. Consequently, Tigris River water in the study area is suitable for drinking purposes in terms of heavy metal pollution.

Six palladium (II) and platinum (II) mixed ligand complexes of metronidazole (mnz) and saccharinate (sac) or benzothiazolinolate (bit) complexes of the type [ML2(mnz)2], M = Pd or Pt, L = sac or bit, have been prepared in moderate to high yield. The newly prepared complexes have been characterized by elemental (C,H,N,S) analysis, conductivity measurements, infrared and 1H-NMR spectra. Characterization data showed that the mnz ligand in all of the prepared complexes is coordinated to metal center through the imidazole nitrogen atom. The (sac) anion ligand is coordinated through the endocyclic nitrogen atom, while the (bit) anion ligand is coordinated through the nitrogen atom in the palladium complex and through the oxygen atom of the carbonyl group in the platinum complexes. The geometry of the Pd (II) and Pt (II) complexes is square planar complexes.

Biometric Technologies in Recognition Systems: A Survey
Authors: Shawkat1 Shihab A. , Ismail2 Raya N.
Published: April 2020

The ability to recognize people uniquely and to associate personal attributes such as name and nationality with them has been very important to the fabric of human society. Nowadays, modern societies have an explosion in population growth and increased mobility which necessitated building advanced identity management systems for recording and maintaining people’s identities. In the last decades, biometrics has played an important role in recognizing people instead of traditional ways such as passwords and keys which can be forgotten or be stolen. Biometric systems employ physiological and/or behavioral characteristics of people to verify their identities. There are different biometric modalities that can be used to recognize people such as fingerprints, face, hand geometry, voice, iris, signature, etc. In this paper, a comprehensive overview have been provided on the major issues of biometric systems including general biometric system architecture, major biometric traits, biometric systems performance, and some relevant works.
