Steganalysis of Chat Based Steganography
Authors: OKELLO Moses Oyaro
Published: April 2023

Steganalysis is the practice of identifying potential secret communication and taking appropriate action, such as deciphering to uncover the hidden contents or destroying the object containing the hidden information if it cannot be uncovered. At times, it’s very necessary to perform Steganalysis due to the fact that steganography is often misused by those with bad intentions, making it a platform for criminal communication. This paper presents a methodology for the detection of timing steganography. The method is based on user behavior during chat, such as the time taken to read, edit, and send text, etc. The method was tested using simulation-based chat software, and it can detect intended timing samples correctly.

1840 թ. հուլիսին Պետերբուրգի գեղարվեստի կայսերական ակադեմիան ոսկե մեդալով ավարտած Հովհաննես Այվազովսկուն գործուղում են արտասահման՝ գեղարվեստի բնագավառում կատարելագործվելու: Այվազովսկին իր ընկերոջ՝ Վասիլի Շտերնբերգի (1818-1845) հետ մեկնում է Իտալիա: Առաջին քաղաքը, ուր ուղևորվում են նրանք, Վենետիկն էր: Ապա այցելում են Վենետիկից ոչ հեռու գտնվող Սուրբ Ղազար կղզի, որտեղ ապրում և աշխատում էր Հովհաննես Այվազովսկու եղբայրը՝ հայ պատմագիր, թարգմանիչ, մանկավարժ, արքեպիսկոպոս Գաբրիել Այվազյանը (1812-1860): Վերջինս եղբորը ծանոթացնում է Մխիթարյան միաբանության գործունեությանը: Դրա շնորհիվ են ստեղծվում «Մխիթարյան հայրերը Սուրբ Ղազար կղզում» (1843) «Բայրոնի այցը Մխիթարյաններին Սբ Ղազար կղզի» (1899) կտավները: Վենետիկի Մխիթարյան միաբանության պատկերասրահում պահպանվում և ցուցադրվում է Հովհաննես Այվազովսկու 14 նկար: В июле 1840 г. Петербургская Императорская академия художеств послала пятерых художников, в их числе и Ивана Айвазовского, окончивших Академию с золотой медалью, за границу для дальнейшего совершенствования мастерства. Вместе с ним в Италию отправился его друг Василий Штернберг (1818-1845). Вначале они посетили Венецию, затем – остров Св. Лазаря, где жил и работал брат Айвазовского – армянский историограф, переводчик, педагог – архиепископ Габриел Айвазян (1812-1860). Последний познакомил своего брата с деятельностью и членами Мхитаристской конгрегации. Впоследстии великий маринист соз-дал полотна «Армяне-мхитаристы на острове Св. Лазаря» (1843 г.) и «Посещение Байроном мхитаристов на острове Св. Лазаря (1899 г.). В галерее Венецианской конгрегации мхитаристов хранятся 14 картин Айвазовского, часть которых демонстрируется посетителям. In July 1840, Hovhannes Aivazovsky was sent on internship abroad by the Imperial Academy of Arts in St. Petersburg. As he left for Italy with his friend Vasily Shternberg (1818-1845), the first city they visited was Venice, where H. Aivazovsky's brother Gabriel Aivazyan (1812-1860), a historian, educator, translator and an archbishop, lived and worked in the Mechitarist Congregation on the island of St. Lazarus. Gabriel introduced the artist to the activities of the Mechitarist Congregation. Impressed by the work done by the Mechitarists, H. Aivazovsky painted "The Armenian Mechitarist fathers on St. Lazare island" (1843) and "Byron's visit to the Mechitarist Congregation on the island of St. Lazare in Venice" (1899). The picture gallery of Mechitarist Congregation houses 14 paintings by H. Aivazovsky.
Տոնը և կոլեկտիվ տրավման. 2021-ի այլ Ամանորը հայկական միջավայրում

2020 թ. 44-օրյա պատերազմով պայմանավորված կոլեկտիվ տրավմայի հուշայնացման թերևս առաջին հանրային մեծ ընդգրկում ունեցող ծեսը դարձավ Ամանորը։ Տոնի և հատկապես ամանորյա տոնի գլխավոր՝ հասարակությանը միավորող գործառույթը հետպատերազմյան շրջանում հատուկ դեր ունեցավ պատերազմի տրավման վերապրելու գործում։ Այն դրսևորվեց հայությանը Հայաստանում, Արցախում և Սփյուռքում կորստի և սգի շուրջ համախմբելու մեջ՝ միաժամանակ ակտիվացնելով պատերազմի անձնականացման և ազգընտանիքի կոնցեպտները։ Այս իմաստով, 2021-ի Ամանորը եկավ վերահաստատելու իր` թերևս առավել կենսունակ կապը վերականգնված նախատոնի հետ։ Տոնական ծանոթ վիզուալ, ակուստիկ, համային-հոտային ձևավորումների փոխակերպումները որդեգրվեցին հանրույթի կողմից լուռ համաձայնության շնորհիվ։ Իսկ տոնի գլխավոր խորհրդանիշը՝ տոնածառը, հավատարիմ ծիսական խորհրդանիշների՝ աշխարհն ամբողջացնելու սկզբունքին, միավորեց համայնքը (ընտանիքի կամ համայնքի բոլոր անդամների այս կամ այն մասնակցությունը տոնածառի հարդարմանը), ազգ-պետությունը (Եռագույնների ներկայությունը) և ընտանիք-պետությունը (զոհված/կենդանի զինվորների ներկայությունը)։ Новый 2021 год стал, пожалуй, первым масштабным публичным ритуалом мемориализации коллективной травмы, причиненной 44-дневной войной 2020 года. Основная объединяющая функция праздника, и особенно новогоднего праздника, сыграла особую роль в послевоенное время, одновременно активизируя концепции персонализации войны и нации-семьи. В этом смысле Новый 2021 год вновь подтвердил свою связь с восстановленным первобытным праздником. Имевшие место трансформации привычных визуальных, акустических, вкусовых и обонятельных оформлений праздника были приняты публикой в результате молчаливого согласия граждан. А главный символ праздника – елка, объединила общину (то или иное участие всех членов семьи или общины в украшении елки), нацию-государство (наличие Триколора) и семью-государство (присутствие мертвых/живых солдат). New Year's Eve was perhaps the first large-scale public ritual of memorialization of the collective trauma caused by the 44-day war in 2020. The main unifying function of the holiday, and especially the New Year holiday, played a special role in the post-war period in experiencing the trauma of the war. It manifested itself in the unification of the Armenians of Armenia, Artsakh and the Diaspora around loss and grief, while simultaneously activat-ing the concepts of personalization of war and the nation-family. In this sense, the New Year 2021 has once again confirmed its perhaps most striking connection with the restored primitive festival. This article discusses the transformation of the habitual visual, acoustic, gustatory, and olfactory designs of the holiday, which were accepted by the public as a result of tacit consent. And the main symbol of the holiday, the Christmas tree, faithful to the principle of completing the world, united the community (participation of all family or community members in decorating the Christmas tree), the nation-state (the presence of the Tricolor) and the family-state (the presence of dead / living soldiers).

Ovo istraživanje donosi sintezu iskazanih vrijednosti tekstova hrvatskih osnovnoškolaca u literarnim radovima poezije, proze i igrokaza na natječaju za književno i likovno stvaralaštvo učenika osnovnih škola u Republici Hrvatskoj pod nazivom Susreti hrvatskoga dječjega duhovnoga stvaralaštva »Stjepan Kranjčić« skraćeno nazvan »Dječji Kranjčić«. Analizirane su vrijednosti u prvih deset zbornika najuspjelijih radova natječaja (2012. – 2021.). Provedena je kvantitativna i kvalitativna analiza podataka. Za potrebe kvantitativne analize vrijednosti rabljen je protokol koji je sadržavao sedam klasificiranih kategorija vrijednosti i njihove potkategorije. U postupku obrade podatka kvantitativnom analizom rabile su se statističke procedure određivanja frekvencija i postotaka, utvrđen je broj objavljenih dječjih književnih radova u svih deset zbornika prema godini objavljivanja, kao i zastupljenost kršćanskih i univerzalnih vrijednosti u dječjem literarnom radu te učestalost pojedinih vrijednosti u potkategorijama. Kvalitativnom analizom sadržaja dječjega književnog stvaralaštva identificirane su vrijednosti koje se promoviraju u trima navedenim književnim rodovima. Na uzorku od 599 objavljenih radova (poezija 270, proza 275, drama – igrokaz 54), zaključuje se da su osnovnoškolci najviše iskazali duhovne vrijednosti poput pobožnosti i svetosti te istinske vjere, što potvrđuje istraživačku hipotezu, dok su na drugom mjestu preferirane univerzalne vrijednosti: ljubav, obitelj, domovina, dobrota. Istraživanje upućuje na odličan primjer suradnje škole i udruge, koje djelujući zajedno mogu imati iznimnu ulogu u razvoju pozitivnih vrijednosti u odgoju hrvatske mladeži.

A GESTÃO COMPARTILHADA DE SERVIÇOS EDUCACIONAIS POR MEIO DOS CONSÓRCIOS PÚBLICOS: O CASO DO CIEDEPAR
Authors: De Lima Roger Pena , Cardoso Mônica Serafim , Castioni Remi
Published: April 2023

Este artigo busca discutir o consorciamento público intermunicipal como meio para contribuir no enfrentamento de problemas comuns dos municípios e para a produção de soluções integradas na gestão da educação básica pública. Considerou, para isso, a perspectiva acerca da questão federativa e da articulação regional entre municípios, tendo como norte a Lei 11.107/2005, que trata dos consórcios públicos. Orientou-se pela abordagem qualitativa e optou-se pela análise documental e pela aplicação de questionário junto aos municípios do Consórcio Intermunicipal de Educação e Ensino do Paraná (Ciedepar). A partir das respostas, realizaram-se entrevistas semiestruturadas com gestores do consórcio e gestores municipais. Como resultado, percebemos que o desenho institucional do Ciedepar objetiva o aprimoramento da gestão da educação em articulação com os municípios para a produção de soluções integradas. Observou-se forte planejamento integrado para a obtenção de metas relacionadas à aprendizagem e ao atendimento educacional nos municípios consorciados. Observou-se ainda, que o desenho institucional do Ciedepar tem sido bastante inovador no campo das políticas educacionais, criando uma rede de implementação de políticas públicas, que se organiza por meios de uma instância intermunicipal, a qual necessita, em alguma medida, da abdicação de determinado grau de autonomia por parte dos entes federados para uma melhor articulação de suas ações.
U-Pb DATING OF APATITE FROM SILVERMINES DEPOSIT, IRELAND: A MODEL FOR HYDROTHERMAL ORE GENESIS
Authors: Vafeas Nicholas Andrew , Slezak Paul , Chew David , Brodbeck Maurice , Hitzman Murray. W. , Hnatyshin Danny
Published: April 2023

Uranium-Pb dating of unusual coarse-grained apatite crystals from hydrothermal dolostone breccia in the barite-rich Magcobar zone at the Silvermines deposit, Ireland, indicates an age of 331 ± 5.6 Ma for hydrothermal alteration. This age is in agreement with an Re-Os age on pyrite-sphalerite but differs from previous estimates that were based on palemomagnetism and sphalerite Rb-Sr geochronology at Silvermines. The new U-Pb age indicates the deposit largely formed epigenetically rather than as a synsedimentary deposit. The trace element composition of the apatite provides additional constraints on the geochemical evolution of the Silvermines hydrothermal system indicating that it was initiated with the expulsion of oxidizing fluids responsible for early hematite-silica precipitation. This was followed by the formation of hydrothermal dolostone breccias containing barite and the apatite dated here. The infiltration of metal-bearing hydrothermal fluids, likely derived from the basement, overlapped and followed the development of hydrothermal dolostone breccias, interacting with Carboniferous seawater during dolomitization and barite precipitation. Near-sea-floor biogenic activity, possibly enhanced due to escape of hydrothermal fluids, resulted in the reduction of seawater sulfate and formation of the sulfide-bearing fluids that facilitated the development of the Silvermines Zn-Pb deposit.
Anti-Fat Bias in the Singing Voice Studio, Part Two: How to Make a Size Inclusive Voice Studio
Authors: Benson Elizabeth Ann , Rosen Kate
Published: April 2023

Singing voice teachers are working hard to be inclusive and progressive in the 21st century. We are aware of our power to create inclusive learning spaces that embrace our students’ identity traits including race, gender, sexual orientation, ability, neurodivergence, and more. However, body size is almost always left out of the discussion of inclusive actions in the voice studio. Fatness is a social justice issue and singing voice teachers can either affirm or further marginalize fat students in the 1:1 training setting of the voice studio. In part one, the authors offer background information on the prevalence of fatness, the history of anti-fat bias, and the experiences of fat persons in healthcare, employment, and educational settings. This context encourages voice teachers to examine implicit anti-fat bias, one of the few remaining yet still widely tolerated cultural biases. Many believe that anti-fat bias can be justified by medical facts, but this belief requires an examination of the influence of money and the media. The authors utilize a fat liberationist framework, rejecting the long-held idea that fat bodies are problematic in the performing arts, and affirming that the performing arts industry must provide opportunities for talented and well-trained performers in bodies of every size to work and tell stories that reflect our diverse world. In part two, the authors explore tangible pedagogical modifications to foster a sense of belonging for all voice students, including fat students. Micro-activism in the voice studio is a huge step toward systemic change, and it can have a profoundly positive impact on our students.
Role of transportation cost in housing affordability for the urban poor in the metropolitan cities in India- a case of Lucknow
Authors: Rao Prabhat Kumar , Biswas Arindam , Singh Gaurav , Abdullah Tabish Ahmed , Kulshrestha Vaibhav
Published: April 2023

Housing affordability is conventionally measured by the thumb rule of 30% of monthly income spent on housing. This thumb rule does not consider location, transportation cost, or accessibility. However, if a residence is far away and requires expensive travel, it is not actually affordable. Multiple planning goals can be accomplished by increasing the availability of inexpensive housing in convenient places, including decreasing transport costs, improving economic opportunities for underprivileged groups, lowering accident risk, conserving energy, and lowering pollution emissions. An H+T affordability index is a tool that is recently developed by researchers to assess the overall cost of housing and transportation relative to household income for different locations in a city. Researchers have recently developed a metric called the H+T affordability index to assess the entire cost of housing and transportation relative to household income for various areas of a city.  This analysis is used in the study of Lucknow, India. The results show that households in suburban areas spend  more than 57% of their monthly income on housing and transportation than those living in central zones and they  spend only 45% of their income on these expenses. This aligns with the findings of other urban regions' studies. This demonstrates the viability of housing and transportation affordability analysis to discover inexpensive and sustainable development in developing countries.
Analyzing Factors Affecting the Conversion Rate for Jeonse to Monthly Payment based on the actual price of Apartments: Focusing on Gangnam 3 districts and 3 non-Gangnam districts
Authors:   Korea Real Estate Policy Association, Yoon Mansik , Won Jae Woong , Kim Sang Jin
Published: April 2023

This study examines the theoretical assumptions and previous studies on the factors affecting the conversion rate for Jeonse to Monthly Payment and conducts an empirical analysis of the determinants of the conversion rate for Jeonse to Monthly Payment. The study covers three regions in Seoul of Gangnam (Seocho-gu, Gangnam-gu, and Songpa-gu) and three regions in Seoul (Gangdong-gu, Yangcheon-gu, and Nowon-gu), which are the most active areas for apartment sales, rental, and leasing transactions. In order to empirically analyze the determinants of the conversion rate for Jeonse to Monthly Payment, this study uses the SVAR model based on theoretical constraints between variables, a methodology developed by Lee (2008). The main influencing factors of the conversion rate for Jeonse to Monthly Payment are the 3-year government bond yield, the conversion rate for Jeonse to Monthly Paymentby region, real estate market consumer sentiment index, and mortgage loan amount. The variables except for the real estate market sentiment index had an impact on the sublease conversion rate. By region, the effect was different, with the conversion rate for Jeonse to Monthly Payment in 3 regions (Gangdong-gu, Yangcheon-gu, and Nowon-gu) responding more strongly than in 3 regions (Gangnam (Seocho-gu, Gangnam-gu, and Songpa-gu).

Students’ Opinions on the Use of Virtual Museums in Science Teaching
Authors: GÜLER Bekir , CENGİZ Ezgi
Published: April 2023

This study aims to present secondary school students’ opinions on a science learning process supported by virtual museum activities. The study was conducted with 29 5th grade students studying at a public school during the academic year 2021-2022. During the study, the science lessons were enriched with virtual museum activities in addition to the activities presented in line with the curriculum and the content of the textbook. As the virtual environment, researchers used the virtual museum of Smithsonian National Museum of Natural History in the USA. After the lessons, semi-structured interviews were held to identify the participants’ opinions on the virtual museum activity. It was observed that all the students had a positive impression and were satisfied with the process even though they addressed the virtual museum experience from different aspects. The students stated that they enjoyed both seeing the remains of creatures that lived in the past and getting information about the creatures they were familiar with. In addition, it was observed that they felt as if they had made a physical visit to the museum and related their learning with the achievements of the course. In the light of the findings, it is thought that virtual museums can be given more place in science lessons.
Efficient multiplication of a vector by a matrix MDS
Authors: Freyre Arrozarena Pablo , Fiallo Ernesto Dominguez
Published: April 2023

Abstract— An algorithm is proposed for the efficient multiplication of a vector by an n x n MDS matrix defined on Fq or by its inverse. The algorithm is based on the multiplication of two polynomials modulo a polynomial of degree n Reed-Solomon code generator and has complexity O(nlog2log2(nlog2q)).
The algorithm only needs to store n values of the Fq field for the multiplication of a vector by an n x n MDS matrix and 2n values for the multiplication of the vector by the inverse matrix.
The The Influence of Petrus Iohannis Olivi (1248-98) upon the Formulation of a Radically Voluntarist Conception of Natural Law
Authors: Whitehouse Dominic
Published: April 2023

The Franciscan thinker, Petrus Iohannis Olivi (ca. 1248–98), was the first latermediaeval thinker to propose a radically voluntarist theory of natural law. While his Franciscan predecessors, in particular Alexander of Halles (ca. 1185–1245), John of La Rochelle (end of 12th century–1245) and Saint Bonaventura(1221–1274) prioritised the higher will (voluntas) over the intellect in respect both to God himself as the providential giver of natural law, and of the human being as the recipient of God’s gift of natural law as an aspect of his eternal law, all these Franciscan thinkers regarded the operation of the intellect and will, first in the Divine and then in human nature in co-operative terms. Olivi is the first thinker to propose the absolute and not simply relative priority of the will in both the Divine creation of the natural law and how it impinges upon, and operates within the human rational faculty. In this brief introduction of Olivi’s theory, I focus on the first of these two perspectives.

Blepharitis is an ophthalmological condition characterized by inflammation of the eyelids. Anatomically, blepharitis is divided into anterior and posterior blepharitis. Therapeutic options for blepharitis have evolved in recent years. Warm compresses and eyelid hygiene are still the basic treatment regimen, but the use of antibiotics, steroids, and calcineurin inhibitors has shown good efficacy. Supplementations and various possible intervention procedures may be considered in the future.

Trữ lượng carbon của đất ở những hệ sinh thái rừng trồng đóng một vai trò quan trọng trong chu trình carbon toàn cầu. Tuy nhiên, những kiến thức và nghiên cứu hiện tại chỉ cung cấp những thông tin hạn chế về trữ lượng và động lực tích lũy carbon trong đất ở các tuổi khác nhau của rừng trồng Keo lai (Acacia hybrid) tại tỉnh Đồng Nai. Nghiên cứu được thiết kế để đánh giá hàm lượng carbon hữu cơ trong đất và trữ lượng của nó theo trình tự thời gian của ba lâm phần rừng trồng Keo lai (tuổi 4, 6, 10) tại Công ty TNHH MTV Lâm nghiệp La Ngà, tỉnh Đồng Nai. Trữ lượng carbon trong đất được đánh giá trong từng lâm phần ở độ sâu 0 - 100 cm bằng phương pháp oxy hóa Kali dicromat. Kết quả cho thấy hàm lượng carbon hữu cơ trong đất tăng đáng kể theo tuổi rừng và giảm liên tục khi độ sâu của đất tăng lên. Trữ lượng carbon hữu cơ ở tầng đất (0 - 100 cm) trong các khu rừng trồng (tuổi 4, 6, 10) lần lượt là 88,8; 114,3; 202,6 tấn/ha. Hơn 57% lượng carbon trong đất được tìm thấy trong độ sâu 0 – 40 cm ở mỗi tuổi lâm phần. Hơn nữa, sinh khối vật rơi rụng là yếu tố chính điều khiển sự hấp thụ carbon hữu cơ trong đất. Những phát hiện từ nghiên cứu này cho thấy trồng rừng Keo lai có thể thúc đẩy trữ lượng carbon hữu cơ trong đất, đồng thời cung cấp dữ liệu để ước tính trữ lượng carbon của hệ sinh thái rừng trồng ở tỉnh Đồng Nai.

Authors: Pinto Agostinho Sousa , Abreu António , Costa Eusébio , Paiva Jerónimo
Published: April 2023

In the last decade, artificial intelligence (AI), machine learning (ML) and learning data analytics have been introduced with great effect in the field of higher education. However, despite the potential benefits for higher education institutions (HIE´s) of these emerging technologies, most of them are still in the early stages of adoption of these technologies. Thus, a systematic literature review (SLR) on the literature published over the last 5 years on potential applications of machine learning in higher education is necessary. Following the PRISMA guidelines, out of the 1887 initially identified SCOPUS-indexed publications on the topic, 171 articles were selected for review. To screen the abstracts and titles of each citation, Rayyan QCRI was used. VOSViewer, a software tool for constructing and visualizing bibliometric networks, and Microsoft Excel were used to generate charts and figures. The findings show that the most widely researched application of ML in higher education is related to the prediction of academic performance and employability of students. The implications will be invaluable for researchers and practitioners to explore how ML and AI technologies ,in the era of ChatGPT, can be used in universities without jeopardizing academic integrity.

Published: April 2023

Background:The family planning program in Indonesia has been started since 1957, but it was merely part of health issues. With the increasing population of Indonesian people, the high maternal mortality rate, and the need for reproductive health, family planning programs are then used as a way to suppress population growth and improve maternal and child health. According to the National Population and Family Planning Board (BKKBN), the primary problem in actualizing the target of family planning programs is the low participation of couples of childbearing age (EFA). Another problem currently emerging is the increasing number of family planning dropouts as a direct impact of the COVID-19 pandemic. Purpose: This study aimed to scrutinize the implementation of family planning programs during the COVID-19 pandemic. Methods: The method in this research was scoping review. The literature search in this study used 3 health journal databases, namely PubMed, ScienceDirect, ProQuest, and 1 search engine: Google Scholar. Articles were selected using inclusion criteria, which were Articles published in national and international journals from 2019 to 2021. The total search results were 274 articles, and 9 articles were found that met the inclusion criteria in the author's review. The instruments used to assess the quality of articles was The Joanna Briggs Institute (JBI) Critical Appraisal Tools.Results:The impact of family planning services in the COVID-19 pandemic era is a decrease in family planning participants in March 2020 when compared to February 2020 throughout Indonesia. Factors that affect family planning program services during the COVID-19 pandemic include : knowledge, Husband’s support, Support from health professionals. Conclusions:The conclusion from the nine articles is that several countries have experienced changes in the system of maternal and child health services and family planning services. Many countries encountered a decrease in family planning participants and the presence of unwanted pregnancies.

Objetivou-se estudar a cinética de secagem de grãos de sorgo para diferentes condições de teores de água iniciais 0,49; 0,40; 0,31; 0,23 kg de água kg-1 de matéria seca, e temperaturas de 40, 60, 80 e 100 ºC, bem como ajustar modelos matemáticos e analisar a taxa de remoção de água. A partir do teor de água inicial dos grãos de sorgo de 0,49 (kg de água kg-1 de matéria seca) foram obtidos outros três teores de água (0,40; 0,31 e 0,23 kg de água kg-1 de matéria seca) por meio da secagem em estufa com temperatura de 40 ºC. Em seguida, os grãos com diferentes teores de água foram submetidos à secagem em estufa com ventilação de ar forçada em quatro condições de temperaturas de 40, 60, 80 e 100 °C. A cinética de secagem dos grãos de sorgo em diferentes teores de água iniciais e temperaturas pode ser descrita pelo modelo de Midilli, não sendo possível a utilização de uma única equação para as diferentes condições de secagem. A temperatura do ar de secagem e o teor de água inicial dos grãos de sorgo influenciam diretamente nos valores da taxa de remoção de água.
Inefficacité de l’urée dans un Arénoferralsol de Kinshasa
Authors: Jared Mataba Mpongate , Kabamba Christophe Lumpungu
Published: April 2023

L’azote est le premier élément minéral limitant le niveau de production de nombreux systèmes culturaux agricoles dans le monde. Paradoxalement, cet élément, qui représente une charge importante pour l’agriculteur, échappe au système et vient polluer les cours d’eau, les nappes souterraines et l’atmosphère. Aussi, les pertes d’azotes, sous diverses formes, est une question des plus préoccupantes dans le monde aujourd’hui.  Dans le cadre de ce travail, nous nous sommes servis de l’urée car, c’est l’engrais azoté le plus concentré (46% N) et le plus largement utilisé dans la pratique agricole en raison de ses autres avantages, notamment le faible coût de transport, de manutention, de stockage et d’épandage. Nonobstant sa concentration, la plus élevée en azote parmi les engrais, son application demande cependant certaines précautions pour contrer sa dissipation, qui limite son efficience dans la pratique agricole. Il ressort de cette étude que l’inefficacité de l’urée observée dans le sol de Kinshasa est due particulièrement à la volatilisation ammoniacale, pouvant aller jusqu’à 12 jours, qui élève le pH du sol jusqu’à un seuil maximum supérieur à 9. Celle-ci est exacerbée par un très faible pouvoir de nitrification de ce sol.

Background and objectives: Cardiac tachyarrhythmias are recurrent/chronic and mostly life-threatening conditions. Diagnosis and treatment of this condition is depending on its patterns and associated comorbidities. This study aimed to assess the pattern of tachyarrhythmia, identify the risk factors and determine the outcome of the management strategy Methods: A prospective observational study was carried out at cardiac center in Sulaimani Teaching Hospital from Januarys 2017 to December 2017. A total of sixty-three patients, aged between (20–90) years old, who presented to the emergency department with tachyarrhythmia were recruited to this study Results: The mean± SD of patients› age was 61.1 ± 16.6 years with a male: female ratio of (1.2). Atrial fibrillation was the commonest type of tachyarrhythmia (61.9%) followed by supraventricular tachycardia (25.4%) and Ventricular tachyarrhythmia (12.7%). Atrial fibrillation was more common in ages above 65 years (36.5%), and 19.1% of supraventricular tachycardia was present among females. Moreover, 14.3% of heart failure and 15.9% of ischemic heart disease were commonly associated with atrial fibrillation. In addition, 38.1% of atrial fibrillation was responded to rate control medications but most of ventricular arrhythmia (4.8%) received a combination of rate and rhythm control drugs. Higher rate of hemodynamic instability (12.7%) was recorded in patients with atrial fibrillation. Conclusions: Atrial fibrillation, supraventricular tachycardia, and ventricular arrhythmia were the commonest types of tachyarrhythmia. Moreover, aging, male gender, heart failure, and ischemic heart disease were significantly associated with atrial fibrillation. In addition, rate-control drugs were used for most of patients.

Background and objectives: Iron deficiency anaemia and beta thalassaemia trait are the most common microcytic hypochromic anaemias, however, coincidence of both has been the topic of few studies. This study carried out to determine if iron deficiency coexists and to which extent, also influence on hemoglobinA2 level and link to demographical and biochemical parameters among ?-thalassemia trait children aged 1 to 5. Methods: A cross-sectional observational study conducted on 112 children with thalassaemia minor diagnosed by blood counts and hemoglobin electrophoresis. The iron status of all children was measured, those with a cut-off value of serum ferritin level <15 ?g/l considered to have coexistence of iron deficiency (group I), furthermore, different variables compared to the remaining children with normal serum ferritin levels (group II). Results: Out of 112 ?-thalassemia trait children, 39 (34.82%) had concomitant iron deficiency, 35.9% females, and 64.1% males, with no significant difference in sex between the two groups. The mean age ± SD was 38 ± 16 months, yet iron deficiency coincidence was significantly higher among the younger children. There was no significant difference between those with or without iron deficiency regarding hemoglobin A2 level. Conclusions: We found that more than one-third of children with thalassemia minor are also iron deficient. Furthermore, serum ferritin level didn’t impact the hemoglobin A2 in thalassaemic minor children with or without concomitant iron deficiency.
