Spectral light absorption by yellow substance and its dynamics in the surface layers of thermokarst lakes of the Central Yamal

The article presents the experimental data on dynamics of light absorption by yellow substance in the surface layer of 52 thermokarst lakes of the Middle Yamal obtained during hydrological, hydrobiological and hydrochemical field investigations in September 2018. In the study period, light absorption by yellow substance in the spectral range 400–700&nbsp;nm was calculated as 0.7–0.9&nbsp;m–1. We measured concentrations of yellow substance Сys and chlorophyll a Chla. The latter had its maximum equal to 12.5&nbsp;mg/m3. Thirty-seven out of fifty-two samples showed 10.0–14.5&nbsp;mg/m3 thus corresponding to oligo-and mesotrophic reservoirs. Eutrophic samples (Chla &gt;30&nbsp;mg/m3) were not registered. Maximum chlorophyll (18.8&nbsp;mg/m3) was detected in site 52. Concentrations of yellow substance in lakes (2.3–19.3&nbsp;g/m3) were defined with the use of the optical method due to the measured coefficient of light absorption by yellow substance at a wavelength of λ=450&nbsp;nm. The correlation between Chla and Сys concentrations in all samples indicated that a low content of chlorophyll (Chla &lt;10&nbsp;mg/m3) was randomly accompanied by a wide range of attenuation Сys (from 0.5 to 3.0&nbsp;g/m3), whereas its high concentrations – similarly, by random but significantly less variation of Сys (from 1.1 to 1.9&nbsp;g/m3).
KITĀBU AL-‘AIN: METODE PENGGUNAAN DAN PENGARUHNYA DALAM PERKEMBANGAN KOSAKATA BAHASA ARAB

The development of language in a group or community is influenced by the systematic changes in daily interaction and communication. Dictionaries become a documentation of language development through syntactic and morphological aspects and then recorded. Kitab al-‘ain written and compiled by Syaikh Khalil has provided a treasure of Arabic vocabulary which is certainly very useful for those who are observers of Arabic and studying it. The formation and alteration of Arabic vocabulary always begins with phonetic aspects which are then documented in the form of writings that are recorded. Therefore, the dictionary as the end result of the lecsycographic work is to gather all the vocabulary in a language and make the dictionary as the container of a set of vocabulary that has a cultural background that serves to accommodate the concepts of Culture of the speaking community. The morphological process of Arabic vocabulary in the dictionary aims to bind utterances which often are not maintained by the formation process so that with the emergence of an Arabic dictionary the order of language is good and correct will always be realized and maintained. Lexicology became the pioneer of the study in the lexicography. It is part of a language study that focuses the research of vocabulary and its meaning as well as its relevance with the dictionary drafting process.

Multiproxy records on the fluvial successions of Assam-Arakan Basin: Implication for paleo-drainage evolution

&amp;lt;p&amp;gt;Assam-Arakan Basin comprises Cenozoic sedimentary successions, located in northeastern India is juxtaposed to both the Himalaya and Indo-Burman Ranges (IBR). The Upper Miocene-Pliocene (Tipam sandstone) and the overlying younger Upper Pliocene-Pleistocene units (Dupi-Tila/Namsang/Dihing) of this foreland basin are fluvial successions. Heavy mineral as detritus provenance indicator has been used as one of the multiproxy records on the fluvial sequences of Assam-Arakan Basin to unravel the drainage system that deposited the same in this basin. Previous workers have advocated that the paleo-Brahmaputra river had initially flowed east of Shillong Plateau before being deflected northwesterly taking the present-day course parallel to the Plateau. However, unequivocal evidence of paleo-Brahmaputra remains enigmatic. The study demonstrates the provenance for the fluvial sedimentary units of the above foreland basin using petrography and heavy mineral distributions. X-ray Diffraction (XRD) and Electron Probe Micro Analyzer (EPMA) analyses were employed to correctly identify the heavy mineral species and support the semi-quantitative analysis of heavy minerals in the basin. The outcome of the study provides new insights towards the paleo-drainage evolution of the river course accountable for the fluvial sedimentation in the Assam-Arakan Basin. Clast petrography and heavy mineral observations indicate the probable source from Lohit- Dibang valley. Initial analysis of detrital zircon U-Pb ages from studied samples reveals major age peaks at around 500 Ma and 1025 Ma with young ages between 16 Ma and ~140 Ma. These samples do not provide ages &amp;lt; 10 Ma, signifying the sediments not derived from Namche Barwa massif, eroded by the Tsangpo-Siang-Brahmaputra river system. It is in contrast to similar sediments in the Siwaliks of NE Himalaya. The data supports our observation that the paleo-Brahmaputra seems not the cause for these deposits, at least during the Pleistocene. If Paleo-Brahmaputra got diverted during this period, it requires scanning the detritus from Tipam units and additional samples from Dupi-Tila/Namsang/Dihing units across the entire Assam-Arakan range to infer source and drainage system for these deposits. We tentatively propose that the Tipam and the younger Dupi-Tila/Namsang/Dihing units in the Assam-Arakan Basin were deposited by drainage flowing from Dibang-Tezu valley, that was initially linked to the Irrawaddy river system. The uplift along Naga thrust caused drainage migration, eventually meeting the present-day Brahmaputra course.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Keywords: Heavy mineral; Detrital zircon U-Pb ages; Paleo-Brahmaputra; Assam-Arakan Basin&amp;lt;/p&amp;gt;
Visual Semagram: An Enhanced Technique for Confidentiality Requirement of Electronic Voting System

One of the rights of citizens in any democratic society is to freely elect a particular candidate into a specific office for governance.This implies that among the candidates participating in an election, one of them would emerge as a winner based on the specified rules and regulation.The recent reports on the election in different parts of the world revealed that the corrupt politicians and corrupt election officers did manipulate the sensitive results thereby leading to undesired candidate emerge as a winner.This implies that election results had not been adequately secured against an attack such as alteration for false results.This paper reviewed scholarly published work and presented a novel technique using visual semagram to satisfy the confidentiality requirement of the electronic voting system.The mathematical equations on how the three primary additive colours (Red, Green and Blue) could be used to modify and conceal the election results against suspicion and alteration were presented.The significance of this paper included the presentation of a technique that would conceal any sensitive message from attackers' suspicion and scholarly piece of information for further investigation in handling insecurity issues.The future work would involve the implementation and evaluation of the proposed technique to achieve the confidentiality requirement of the e-voting system, and to establish the validity and reliability of proposed technique.

Mobile Devices for Arabic Learning in Junior High Schools: The Teachers’ Perspective

The present study aims to identify teachers' perceptions of mobile devices use in Arabic learning at junior high schools. Employed a qualitative method with a case study, 24 Arabic language teachers from various junior high schools in the South Tangerang City involved in this study selected by using a random sampling method. Based on the teacher perspectives, the results of the study reveal that the use of mobile devices facilitates students in understanding Arabic lessons and increase their motivation for learning. Time limitations and large classroom sizes were obstacles that decrease teachers’ interest to integrate mobile devices into classroom activities. Reading is by far the main language skill taught by teachers and there is a less focus on productive skills such as speaking and writing. The students have less attention and motivation for learning Arabic while the teachers have attempted to deal with this problem by several measures.The characteristic of Arabic language differs from each context. However, whether for inside or outside classroom activities, active methods are of particular importance for Arabic learning. Arabic teaching and learning practices facilitated by mobile devices require careful planning for a successful implementation lead to more active and effective learning of Arabic.
