Sedimentary Basin Reconstruction and Tectonic Development of Paleocene-Eocene Succession, Southern Iraq, by Geohistory Analysis
Authors: Menshed Mahdi Ali , Al-Zaidy Aiad Ali Hussien 
Published: May 2021

The Paleocene-Early Eocene sequence is represented by Aliji and Umm Er Radhuma formations, while the Middle-Late Eocene sequence is represented by Jaddala and Dammam formations. The Rus Formation has been described and its basin was analyzed separately because it was deposited during the regression period (Middle Eocene), which is a transitional period between these two cycles.
This study includes analysis of the geohistory of this succession, interpretation of the changes of the accumulation, and calculation of subsidence rates. The results were compared with the space available to explain the basin development. The study site included the boreholes of Garraf-84 and 92, Halfaya-1, Nasirya-13 and 40, and Noor-5 at the Mesopotamian Block, in addition to the Ratawi-8, Tuba-15, Rumaila-217, Zubair-45, and West Qurna-60 at the Basra Block.
The Aliji basin was characterized by the decrease in accommodation values to the northeast direction and the increase in all the other parts of the study area. A comparison of the setting of this basin with the Umm Er Radhuma basin gives a clear evidence of the tectonic impact coming from the northeast. During the Middle Eocene stage, we notice that the basin was affected by comprehensive uplifting processes. This led to the generation of a very shallow basin (Rus basin) with the exposure of the northern part of the basin during the regression stage.
The Middle-Late Eocene basin is represented by a transgression stage with high subsidence, where the sea level had been raised and covered the northeastern and eastern parts of the studied area by deep sea deposits (Jaddala Formation). While the other parts of the study area were characterized by shallow sediments of Dammam Formation. This period ended with a clear tectonic uplift occurring in the northeastern parts and decreasing towards the southwest. This confirms the reactivation of the tectonic action from the northeast, represented by the continental collision.
All these sources of evidence indicate that the study area is divided into a northern part and a southern part. Both of these parts are separated by a major tectonic lineament extending from the West Qurna oil field to the Nasiriya oil field, which confirms the presence of the tectonic boundary between the Mesopotamian block and the Basra block. In addition, there exists a secondary tectonic boundary that divides the Mesopotamian block into two parts, the first is to the east and the other is to the west. The results showed that the eastern side was most affected by the collision of the Iranian Plate with the Arabian Plate, which led to its uplift, while the western side was less affected by this tectonics evidence.
Antimicrobial effect of a cyclic peptide Nostophycin isolated from wastewater cyanobacteria, Nostoc calcicola
Authors: Gupta Vaishali , Vyas Deepak 
Published: May 2021

Different types of peptides are produced by cyanobacteria of the genus Nostoc, which are unique in structure and have a wide spectrum of biological activities. The objective of the study to explore different habitats of organism and study antimicrobial activities to improve their pharmaceutical application and drug like properties by structure modification. A cyclic peptide nostophycin was isolated from Nostoc calcicola (MK506349) through freeze dried lyophilization method. Its structure has been elucidated with FT-IR, 1HNMR, 13CNMR and LC-MS. Glycine, d-glutamine, l-phenylamine, d-isoleucine, l-proline and a novel amino acid Ahoa are constituents of nostophycin. 1HNMR, 13CNMR spectroscopy confirmed the number of protons and carbons, and characteristics peak determined the structure and fragmentation pattern through LCMS. Nostophycin possess Ahoa instead of Adha which makes it different from microcystin. Nostophycin exhibits antimicrobial activity against E.coli, S. aureus, C. albicens and A. niger. A good antifungal activity (9-52 μg/mL) and moderate antimicrobial activity (concentration 18-52 μg/mL) were found for nostophycin. In case of already known peptides, these molecules may be further exploited to improve pharmaceutical application and future drug development.

Digitization of analog signals
Authors: Zaitsev A. V. 
Published: May 2021

We live in the world of digital technologies – everyone has a digital phone, television has switched to a digital broadcasting format as it is more noise-immune, digital processes are literally in every household appliance, from the iron to the computer on which this article was written. Digital technologies simplify our lives, some operations performed by humans require large material costs, for example, writing text on a typewriter and computer vary greatly. The gain of the computer is especially evident when editing the test. They brought us comfort – how nice it is when the processor that monitors the temperature in the house increased the heat supply during a cold snap or reduced it in order to save money in the absence of people in the house.But in order for the digital system to perform this or that action, it needs a command coming from the sensor. It can be a temperature, humidity, pressure sensor. Or maybe a microphone used in voice control systems. All these sensors, without which the operation of a digital system is impossible, give an analog signal that changes its value over time. The digital system is not sensitive to such a signal. It “does not understand” the signal. The problem is solved by ADC (analog-to-digital converters). They have a different structure, varying degrees of complexity, the device, depending on the parameters of the digitized signal. For example, the temperature in the house changes very slowly, even when warming up or when the heating is turned off in frost, the temperature rises or, accordingly, does not fall faster than one degree per hour. The ADC speed requirements for the temperature sensor are very low. Instead, a microphone is used to receive voice commands. In order to distinguish the voices of people and to carry out the commands of some people and not to carry out commands from others, processing of the signal spectrum with a width of kilohertz is required - which means that the signal level will change at a frequency of thousands of times per second. This is a very high demand. The different types of ADCs, their design and application will be discussed in this article.

As centrais de triagem têm um papel importante no processo de reciclagem de resíduos sólidos uma vez que viabilizam a separação dos diferentes tipos de materiais que compõem os resíduos para que os mesmos possam ser reutilizados ou transformados em novos produtos. Atualmente, a cidade de Campina Grande não dispõe de um programa de reciclagem e reutilização de resíduos em todo o municipio, mesmo sendo obrigatório segundo as diretrizes da Política Nacional de Resíduos Sólidos. Com isso, é necessário a implantação de uma central de triagem na cidade que realize a segregação de todos os resíduos gerados, para que as etapas de reutilização e reciclagem sejam viabilizadas. A central de triagem proposta para a cidade de Campina Grande-PB é do tipo semiautomática com o uso de esteiras e catadores para auxiliar na segregação dos resíduos. O presente manual apresenta especificações sobre os detalhes construtivos, organização do galpão e cotação dos equipamentos.

Authors: Sulhaini  , Rusdan  , Dayani Rahman 
Published: May 2021

Desa Bukit Tinggi memiliki potensi wisata yang cukup besar terutama wisata yang memanfaatkan alam. Upaya-upaya untuk pengembangan potensi wisata ini diperlukan untuk membantu peningkatan kesejahteraan masyarakatnya, salah satunya adalah implementasi manajemen pariwisata berkelanjutan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan wawasan kepariwisataan dan kemampuan dalam menerapkan manajemen jasa pariwisata berkelanjutan bagi Pokdarwis desa Bukit Tinggi. Pelaksanaan kegiatan dilakukan dengan menyiapkan materi dengan matang, berkoordinasi dengan pokdarwis dan melaksanakan pelatihan manajemen jasa pariwisata berkelanjutan. Setelah kegiatan pelatihan selesai, tim melakukan pendampingan selama dua bulan. Sejak awal kegiatan hingga selesai, tim mengedepankan protokol kesehatan. Adapun kesimpulan yang dapat diambil dari kegiatan ini adalah sebagian besar peserta belum memahami manajemen jasa pariwisata berkelanjutan, terlihat dari masih kurangnya pemahaman tentang sifat jasa dan strategi pemasaran jasa pariwisata, wawasan kepariwisataan berkelanjutan, pasar dan pemasaran pariwisata. Keaktifan peserta saat pelatihan cukup tinggi terlihat dari suasana diskusi dan tanya-jawab. Hal yang menarik dari kegiatan pelatihan ini adalah Pokdarwis desa Bukit Tinggi berencana menambah paket wisata sesuai dengan potensi waduk Meninting yang sedang dibangun, seperti; triatlon (lari, renang,bersepeda), dan rekreasi waduk (sampan tradisional, sampan mesin). Namun demikian, masih ada kendala infrastruktur jalan, masalah sampah, belum melibatkan banyak element masyarakat karena sebagian dari mereka bersikap negative terhadap pariwisata
