A Major role in oxidation kinetics is to determine the reaction mechanism that comprise chemical reaction. In the present paper we derived rate law for reaction mechanism and to recognized the order of reaction, give rate equation, calculate the rate constant. Identify the product of this oxidation reaction.The chemical oxidation of 2-Amino-4-methyl thio-butanoic acid by Quinaldinium Fluorochromate was studied in 50-50 (v/v) selected hydrophilic solvent medium at 308 Kelvin. The reaction is acid catalysed and exhibits first order dependence with respect to oxidant, substrate, and fractional order respect to H+ ion concentrations. Chemical oxidation kinetics is the study of the rate of chemical reaction.the factors Manganesh sulphate, Acrylonitrile, Sodium perchlorate that affect these rates (or) not, and draw of ln Kobs/T verses 1/T energy diagram to find the activation energy. Addition of sodium perchlorate slightly decreases the rate of reaction. However, Acrylonitrile is not induced by the polymerization reaction, showing that there is no free radical route. Added Mn2+ increases with slightly increase rate in the reaction medium. 2-Amino-4-(MethylThio)-Butanoic acid by Quinaldinium Fluorochromate has not been reported. Hence, the investigation of oxidation of 2-Amino-4-Methyl Thio-Butanoic acid by QNFC in selected hydrophilic solvent medium and the corresponding mechanistic aspects are discussed in this research paper. A systematic kinetic work carried out to explore the physical characterization of the reactance. The characterstic effects like Substrate, Oxidant, Perchloric acid, Solvent, Sodium perchlorate, Acrylonitrile, Manganes sulphate and Influence Temperature it clearly shows effect on that reaction path. The process was carried out at four different temperatures to determine the activation conditions. The measured kinetic findings ΔH# and ΔS# are derived from the value.

The uninvited guests of our microbiome: Helicobacter pylori and Epstein-Barr virus and their role in gastric cancerogenesis
Authors: Dzikowiec Magdalena , Pastuszak-Lewandoska Dorota 
Published: November 2021

Abstract
It is well established that human body is an ecosystem for numerous microorganisms: bacteria, fungi, eukaryotic parasites, and viruses. They form a “microbiome” that under conditions of homeostasis remains in a friendly mutual relationship with the host. However, the composition and diversity of this microbe community is dynamic and can be changed under the influence of environmental factors, such as diet, antibiotic therapy, lifestyle, and the host’s genotype and immunity. The result of gut microbiome dysbiosis can lead even to cancer. The aim of this review is the description of the healthy gastrointestinal microbiome and the role of two infectious agents: Gram-negative bacteria Helicobacter pylori and Epstein-Barr virus in the development of gastric cancer in terms of gut dysbiosis. H. pylori is the most important pathogen of gastric microbiome with clear impact on its diversity. Coinfection with Epstein-Barr virus causes chronic gastritis, and the inflammatory process is significantly increased. The process of carcinogenesis begins with chronic inflammation that causes atrophic gastritis, intestinal metaplasia, dysplasia, and finally cancer. It has been proven that chronic inflammatory infection caused by infectious agents increases the risk of stomach cancer. Molecular methods that are progressively used to explore the human microbiome provide hope that this knowledge will be used for future diagnoses and therapy in the state of its dysbiosis and in cases of gastric cancer.
Jak HPV wysokiego ryzyka indukuje optymalne środowisko dla własnej replikacji w różnicującym się nabłonku

Abstrakt
Wirusy brodawczaka ludzkiego (HPV) są często czynnikami wywołującymi niegroźne dla człowieka infekcje, ale przetrwałe zakażenie niektórymi typami HPV jest poważnym zagrożeniem dla zdrowia, ponieważ jest związane z wieloma nowotworami, w tym z rakiem szyjki macicy oraz rosnącą liczbą nowotworów głowy i szyi. Cykl replikacyjny HPV jest ściśle zależny od różnicowania komórek wielowarstwowego nabłonka, co oznacza, że genom wirusa musi być replikowany za pomocą różnych mechanizmów na różnych etapach różnicowania komórek. Ustanowienie infekcji i utrzymywanie genomu wirusa zachodzi w proliferujących komórkach nabłonka, gdzie dostępność czynników replikacji jest optymalna dla wirusa. Jednak produktywna faza cyklu rozwojowego wirusa, w tym produktywna replikacja, późna ekspresja genów i wytwarzanie wirionów, zachodzi w wyniku różnicowania się nabłonka w komórkach, które prawidłowo opuszczają cykl komórkowy. Wirus wykorzystuje wiele szlaków sygnalizacyjnych komórki, w tym odpowiedź na uszkodzenia DNA (DDR, DNA damage response) do realizacji produktywnej replikacji własnego genomu. Zrozumienie mechanizmów związanych z cyklem replikacyjnym HPV jest potrzebne do ustalenia właściwego podejścia terapeutycznego do zwalczania chorób powodowanych przez HPV.

Published: November 2021

Abstract
This paper presents a method that binds statistical and data mining techniques, which aims to support the decision-making process in selected diseases of the digestive system. Currently, there is no precise diagnosis for ulcerative colitis (UC) and Crohn’s disease (CD). Specialist physicians must exclude many other diseases occurring in the colon. The first goal of this study is a retrospective analysis of medical data of patients hospitalised in the Department of Gastroenterology and Internal Diseases, Bialystok, and finding the symptoms differentiating the two analysed diseases. The second goal is to build a system that clearly points to one of the two diseases UC or CD, which shortens the time of diagnosis and facilitates the future treatment of patients. The work focuses on building a model that can be the basis for the construction of action rules, which are one of the basic elements in the medical recommendation system. Generated action rules indicated differentiating factors, such as mean corpuscular volume, platelets (PLTs), neutrophils, monocytes, eosinophils, basophils, alanine aminotransferase (ALAT), creatinine, sodium and potassium. Other important parameters were smoking and blood in stool.

Abstract
Human skin has been classified as a non-volatile memristor and it is shown that information can be stored within for at least three minutes. Here we investigate whether it is possible to store information up to 20 minutes. Furthermore, we investigate whether the information can be based on four different states, not just two (binary). We stored the information into the skin of the forehead of the test subjects under three different electrodes, which allows in principle for 64 different combinations (3 electrodes, 4 states) and one can think of numbers on the base of four. For this experiment, we decided on the numbers 1234 and 3024 (that correspond to numbers 27 and 50 in the decimal system). Writing of the different states was done by the application of DC voltage pulses that cause electro-osmosis in the sweat ducts (nonlinear electrical measurements). Based on our results, we were not able to distinguish between four different states. However, we can show that binary information storage in human skin is possible for up to 20 minutes.

Published: November 2021

Abstract
The aim of this paper is to analyse political activity in the mass media discourses of states with more democratic and more authoritative regimes respectively, so as to show a clear difference in the context of a formal analysis of mass media content. The current study examines political news on qualitative online media portals in Lithuania, Belarus and Ukraine. Thirty years ago, these states began their independent transition from a closed system to openness/democracy. However, at today’s transition point, only Lithuania is considered a democratic country. In different periods Ukraine has been considered an example of competitive authoritarianism, while Belarus deviated towards complete authoritarianism and dictatorship. All political news items between 2005–2020 (for delfi.lt – since 2007) were collected with the help of the Python program. To measure the indicators, several Python programs were designed. The results of the research confirmed that the intensity of political activity differs in the mass media discourses of states with more democratic (Lithuania, Ukraine) and more authoritative (Belarus) regimes. Furthermore, a clear difference was shown in terms of five indicators, average indicators and the dynamics thereof.

The study aims at ascertaining the actual implication of bride pricing system in traditional marriages in Igbo land. A total of fifty respondents (thirty women and twenty men) from the five states that make up the southeast zone in Nigeria were selected for the study. Being a qualitative research, the study adopted the ethnographic research design and employed a purposive non-probability sampling method in selecting the respondents. The study made use of focused group discussions, unstructured interview and participants’ observation method as instruments of data collection. The collection of data lasted for a period of six months from June 2020 to November 2020. The research is anchored on Radical and Snail sense Feminism theories and data for the study were analysed using descriptive thematic method. Findings from the study reveal that payment of bride price does not reduce women to mere commodities in Igbo land. It also reveals that it gives undue privileges to men in Igbo land among other findings. Finally, it was shown that Igbo men and women still regard bride price payment as an important aspect of their culture which should not be abolished.
IMPLEMENTATION OF THE GREIMAS NARRATIVE STRUCTURE ON ULAT ENTADUK STORY (ORAL LITERATURE OF MALAY MEMPAWAH)
Authors: Asyura Muhammad 
Published: November 2021

This research is a qualitative study describing the narrative structure of Ulat Entaduk story as one among the oral literature (fable) living in Malay society in Mempawah. The source of this research data are two native speakers from Mempawah with data in the form of fable stories. The Data was analyzed with a literary study using Greimas narrative structure theory. The results of this study showed that the acution and functional schemes of Ulat Entaduk story is based off the inner conflict of the main character namely the mother and her childish adoptive son (blood-sucking worm) to torment the inner and physical mother. This happened because she too spoiled for her adoptive child that threatened her and family life. The most striking extrinsic element in the Caterpillar's story is self-immaturity and a family education that belongs to sex education. Readers are also taught to be thankful, respect for parents, and live independently as a key to the happiness of life.

Published: November 2021

In the literature, the drying mechanism were generally analyzed in terms of effective diffusivity through the pseudo first order diffusion model. This process was revisited through the modified Peleg model, assuming the drying as a moisture desorption versus drying time. The leaves of Corymbia citriodora acclimatized in the Congo Brazzaville “Plateau des Cataractes” were dried in open air and under shade thanks to a domestic scale of essential oil production. One obtains following model parameters: kinetic constant k1: 0.8555 - 2.1355 d.(g/g)-1, extraction capacity constant K2: 1.5255 - 1.8733 (g/g)-1; end equilibrium moisture X∞ = 0.53 - 0.66 g/g. and first order drying kinetic constant k = K2/k1: 1.71 - 1.78 d-1. Pseudo first order diffusion model fits experimental data with k = 0.368 - 0.587 d-1 and t1/2 = 1,18 - 1,88 d.. These results needed for the optimization of proccess and sizing equipments came from a fast graphic data processing, with low computer inputs.

Deteksi Covid-19 umumnya menggunakan tes laboratorium dengan metode RT-PCR untuk mendapatkan hasil yang akurat. Sayangnya, tes ini membutuhkan waktu yang cukup lama yaitu sekitar 24 jam untuk mendapatkan hasil. Selain menggunakan RT-PCR, beberapa penelitian menunjukkan bahwa deteksi menggunakan citra sinar-X menunjukkan hasil yang cukup akurat dengan waktu prediksi yang lebih cepat. Citra sinar-X yang didominasi warna dalam jangkauan grayscale dapat dikatakan memiliki karakteristik yang berbeda jika dibandingkan dengan citra secara umum, sehingga dalam penelitian ini eksperimen dilakukan terhadap pelatihan untuk kasus klasifikasi citra sinar-X dengan melatih model dari awal (scratch). Namun seringkali model yang dilatih tanpa adanya pretraining menyebabkan model tidak dapat mencapai performa yang cukup baik. Salah satu bentuk metode pretraining yang dapat digunakan adalah penggunaan autoencoder sebagai model untuk rekonstruksi citra. Dalam penelitian ini pelatihan menggunakan pretraining autoencoder menghasilkan akurasi terbaik sebesar 81.78% dengan tambahan metode CutMix, color manipulation, dan rotation sebagai augmentasi. Kami juga menunjukkan bahwa penambahan pretraining autoencoder secara konsisten dapat meningkatkan akurasi hingga 2.58% pada model yang dilatih dari awal (scratch).

Published: November 2021

Abstrak Kapal tradisional yang berada pada jalur pelayaran di Maluku, khusus pada jalur pelayaran Ambon-Manipa memiliki peran penting sebagai salah satu moda transportasi di Maluku. Kapal-kapal kayu ini dibangun tanpa melalui kajian ilmiah, tetapi hanya berdasarkan pengalaman turun- temurun dalam menentukan panjang kapal, bentuk lambung, daya muat serta ukuran lainnya. Hal ini sangat berpengaruh terhadap hambatan kapal sebab jika nilai hambatannya besar, sangat mempengaruhi operasional kapal dan dapat merugikan pemilik kapal itu sendiri. Itulah sebabnya tujuan penelitian ini adalah untuk mengaji ulang secara ilmiah dengan menggambar model kapal yakni lines plan dari kapal yang terpilih dengan kecepatan yang ada, hambatan sekecil mungkin dengan daya muat sebesar mungkin. Metode AHP( Analytic Hierarchy Proces) adalah metode yang digunakkan untuk pemilihan kapal dari lima buah kapal yang ada pada jalur pelayaran Ambon- Manipa. Berdasarkan hasil survey di lapangan dan pengolahan data, terpilih KM Cahaya Rahma. Hasil yang diperoleh menggunakan aplikasi Maxsurf adalah perhitungan hidrostatik untuk mengetahui displasemen kapal atau berat kapal total saat garis air penuh sebesar 25.67 ton. Nilai hambatan dan daya kapal adalah 4.96 kN dan 23.004 kW pada saat kecepat an kapal 9 knot.

Abstrak PT. Dok dan perkapalan Waiame Ambon adalah perusahaan reparasi kapal yang memiliki dua fasilitas pengedokan dengan menggunakan sistem airbag dan cradle. Pengamatan di galangan, sistem airbag dilengkapi dengan winch, kompresor dan alat berat (excavator) pada proses docking/undocking kapal sedangkan dengan sistem cradle dilengkapi dengan winch dan operator penyelam pada proses docking kapal. Proses dan waktu docking/undocking baik dengan sistem airbag dan sistem cradle akan berbeda, dengan kondisi ini maka biaya operasional (docking/undocking kapal) perlu diperhitungkan. Biaya operasional docking/undocking kapal dengan sistem airbag sebesar Rp 25.000.000,- dan sistem cradle sebesar Rp 20.000.000,-. Perbedaan biaya operasional dari masing-masing sistem pengedokan ini dapat mempengaruhi biaya operasional docking/undocking kapal pada perusahaan. Tujuan penelitian ini adalah memperoleh nilai ekonomis yang didapat oleh perusahaan dengan menggunakan sistem airbag dan sistem cradle. Penelitian ini melakukan perhitungan meliputi biaya listrik winch, biaya listrik kompresor, biaya operasi alat berat (excavator), biaya operasional (docking/undocking kapal), biaya docking harian dan kebutuhan tenaga kerja. Dari hasil perhitungan diperoleh bahwa biaya pengeluaran untuk sistem airbag dari tahun 2017-2019 sebesar Rp 760.483.125 dan sistem cradle sebesar Rp. 519,091,188, sedangkan pendapatan yang didapat dari sistem airbag sebesar Rp. 3,593,750,000 dan sistem cradle sebesar Rp. 1.728.750.000. Dari hasil di atas pendapatan terbanyak adalah pendapatan sistem airbag di tahun 2019 yaitu 79 %. Hal ini disebabkan karena lama waktu pengedokan pada sistem airbag lebih banyak walaupun jumlah kapal hanya 14. Keuntungan yang diperoleh dengan penggunaan sistem airbag per tiga tahun yaitu tahun 2017-2019 adalah sebesar Rp. 2.833.266.875,- , lebih besar jika dibandingkan dengan keuntungan yang didapat dengan menggunakan sistem cradle sebesar Rp. 1.209.658.812,50. Terlihat jelas bahwa penggunaan sistem airbag lebih menguntungkan.
