Physics of Respiratory Pathogen Transmission Through Droplets and Aerosol
Authors: Terček Jure
Published: April 2023

Recent epidemic of the COVID-19 (CoronaVirus Disease-19), caused by SARS-CoV-2 virus exposed great gaps in the understanding of respiratory transmitted diseases in many public health institutions. Traditionally, respiratory pathogens are believed to spread through: direct physical contact (like spray of droplets onto mucous membrane), indirect contact with contaminated surfaces (known as “fomites”) and inhalation of aerosols. Public health has relied on a strict split between heavy falling droplets and lighter airlingering aerosols. In this review we take a look at this distinction, comment on potential problems of its definition and examine a few basic physical phenomena affecting airborne droplet behaviour. We conclude that droplets smaller than 10 µm tend to linger in the air for extended periods of time and that air circulation has a big impact on the presence of pathogen-carrying particles in the air, which may help craft better public health policy.

Materials of Absorbable Tracheal Stents and their Potential use for Treatment of Canine Tracheal Collapse
Authors: Novak Manca , Erjavec Vladimira
Published: April 2023

Tracheal collapse in dogs can be treated by inserting tracheal stents. Currently used methods are placement of silicone or metallic intratracheal stent or extraluminal prosthetic rings, which have many post-operative complications and relatively short median survival times. The recent research is oriented in development of absorbable tracheal stents. Absorbable materials are showing great potential in preventing granulation formation, furthermore, the possibility of slow release of drugs incorporated into the stent could add to prevention of restenosis and even affect the tracheal cartilage properties. However, complications such as stent migration and fragmentation during degradation lead to many losses in in-vivo research. The aim of this article is to provide an overview of the current research on absorbable materials for tracheal stents, their complications, and advantages. Keywords: Canine tracheal collapse; Absorbable materials; Copolymers; Drug release; Granulation prevention
Thermography as an Aid in the Performance Testing of Lipizzan Horses
Authors: Kruljc Peter
Published: April 2023

The athletic results or training performance of Lipizzan horses are hardly known in equestrian sports, because they rarely participate in equestrian sports. The aim of this study was to determine the values of physiological parameters of horses with emphasis on the temperature changes of the body skin areas by thermography and to investigate their acclimatization to different training loads. The study included 6 purebreed Lipizzaners with a mean age of 9 years and consisted of two work tests (spring, autumn) that included lunging at walk, trot and canter. Measurements were taken before and after the work tests and were within normal limits for warm-blooded horses in both experiments. In both experiments, body skin temperatures at rest were different between different areas or body parts. After the work test, temperatures in all body skin areas were significantly elevated compared to those measured at rest and then decreased during the rest period after the work test (recovery period) in the fall or remained nearly unchanged in the spring. This study contributes to the knowledge of thermoregulation and the use of thermography in horses, and the results not only demonstrate the physiological responses to graded exercise in Lipizzan horses, but also contribute to the knowledge of equine physiology and sports medicine. The results of our research also contribute to the establishment of standards and protocols for monitoring readiness and progress in training Lipizzan horses and provide relevant data for monitoring health status, athletic ability, and assessing welfare of horses.

The role of the Concomitant Lesions in Determining Failure of Anterior Cruciate Ligament Reconstruction
Authors: Russo Arcangelo , Costa Giuseppe Gianluca
Published: April 2023

Anterior cruciate ligament (ACL) tear is one of the most common sport-related injuries and the request for ACL reconstructions is increasing nowadays. Unfortunately, ACL graft failures may occur in about 5.2% of cases. Unrecognized concomitant meniscus and ligamentous lesions are estimated to be responsive of about 15% of ACL reconstruction failures. Isolated ACL reconstruction in this setting may not be enough to properly restore knee stability. If not properly treated, such lesions may expose ACL graft to excessive stress, thus predisposing to failure. This article aims at highlighting the role of associated lesion in determining failure of ACL reconstruction, while also providing an evidencebased algorithm about proper management. Keywords: Anterior cruciate ligament reconstruction; Failure; Concomitant lesions; Meniscus; Medial collateral ligament; Posterolateral corner
Femoroacetabular Impingement
Authors: Kovačić Borut , Zore Lennart Andrej , Stražar Klemen
Published: April 2023

Femoroacetabular impingement (FAI) is an anatomical hip condition caused by malformations on femoral head and acetabular rim resulting in abnormal contact across the joint. FAI can cause the labral, cartilaginous, and tissue damage that leads to early osteoarthritis. FAI can be divided into three groups: cam (bump on femoral head- neck junction), pincer (acetabular over coverage), or mixed (most common) by the characteristic morphological changes of the bony structures. The exact ethology of FAI is still unclear, mostly considered as idiopathic. Cam lesions demonstrate a near 3:1 male predominance and are more often seen in the younger population. Pincer is typically seen in middle-aged women. A plain radiography of the pelvis and hips is considered as the primary imaging modality for diagnosing FAI, which can be used to quantify the severity. MRI and direct MRI arthrography allow assessment of concomitant labral and chondral injuries. Conservative treatment is typically considered first-line treatment for mild to moderate FAI syndrome, but usually not to successful. However, the outcomes following postoperative surgical intervention have demonstrated excellent results. The most common surgical treatment option for FAI is done arthroscopically, other procedures such as a reverse periacetabular osteotomy or surgical dislocation of the hip are rarely indicated. Keywords: Femoroacetabular impingement; cam, pincer; hip arthroscopy
The Use of Tranexamic Acid in Orthopaedic Surgery
Authors: Kocjančič Boštjan , Kocjančič Ema
Published: April 2023

New surgical techniques (minimally invasive surgery – (MIS), laparoscopic surgery), meticulous consideration of haemostasis, use of robots, Cell Saver and tranexamic acid, new transfusion criteria and single red blood cell (RBC) unit ordering have greatly changed clinical practices. Implementation of these therapeutic options along with other practices has significantly contributed to the effectiveness of the patient blood management approach to surgical patients. In recent years use of anti-fibrinolytic agent tranexamic acid (TXA) has been introduced at our department and intravenous administration as well as topical TXA administration were successfully implemented. Use of topical TXA was effective at reducing both post-operative red blood cell loss and transfusion rates with good tolerance and no clinically relevant adverse events. Within 6 years of Patient Blood Management (PBM) protocol implementation in our institution, the total number of transfusions was reduced by 76 % and the percentage of patients requiring transfusion fell from 38 % to 9 %.

Published: April 2023

Along with the development of the industrial sector in Indonesia, Karawang has excellent opportunities and potential to develop in this field, where Karawang currently has congestion problems from and towards industrial estates in a certain period. The geometric planning of the access road to the Jakarta-Cikampek Toll Road aims to provide references and preliminary designs to unravel the congestion problem. Systematic calculations and integrated visual depictions of AutoCAD Civil 3D® software assist the geometric design process of such roads. The research method used is quantitative. The necessary data sources are obtained from observation methods, literature studies, and primary data. Planning begins with determining the design criteria of the purpose and the function of such roads. Then the design criteria are used as a reference to determine variables in horizontal and vertical paragraphs. From the results of horizontal paragraph planning, one arc of FS (Full Circle) and 2 SCS (Spiral-Circle-Spiral) were obtained. Then the results of the vertical paragraph design got two concave arches.

Published: April 2023

Easy community life, both in terms of economic, social, educational, and others, is the purpose of designing and constructing access roads or connecting roads. In addition, road design must consider safety aspects to achieve safe, balanced, and sustainable road performance. In this study, a manual horizontal alignment road design was carried out to link the road of Jalan Plupuh Tanon and Jalan Gabugan Sragen Section 1 from STA 0 + 000 to STA 2 + 257,221 with the planning of three bend points guided by Highway Design Standard of Indonesia 2021. Primary data in the form of coordinates and contours are taken from Google Earth and the Global Mapper. The design starts by managing primary data and calculating the elements that make up the horizontal alignment so that a road with a design speed of 30 km/h is obtained, the value of e = 8%, and a radius of 200 m. Three horizontal alignment points use a Spiral-Circle-Spiral (SCS) arch with an intermediate curve (Ls) value of 38 m and a circular arch (Lc) of 44.229 m, respectively.
Gyroscopic Model of Electron Charge
Authors: Greve Juris
Published: April 2023

This paper, within the framework of classical physics, offers a gyroscopic model of the electron charge based on possible processes in the early stage of atomic formation in the Big Bang. It allows us to explain the relative stability of atoms and also the situations occurring in electromagnetic processes when the object moves perpendicularly to the forces of action. The proposed electron charge model not only does not contradict the empirical Maxwell equations but complements their explanations by analysing a number of electromagnetic processes in their research and practical application, including the duality of defining the current unit.

In Kashmir Cancer esophagus has a high incidence in both males and females with a sex ratio of approximately 2:1 followed by cancer lung and stomach in males and cancer breast and ovary in females. The most familiar type of cancer diagnosed worldwide among women which contribute around 15% of mortality is breast cancer. We know breast cancer is the most common type of cancer diagnosed in women worldwide contributing around 15% of mortality. In India the second most familiar cancer among women is breast cancer and the incidence of breast cancer among women is twice in rural areas as compared to urban areas. The current study was conducted to examine the existing levels of consciousness among rural women in which we chose 400 rural women at random for our study on their consent. A well developed validated questionnaire was used for the collection of data and data collected was analysed using appropriate statistical tools. The study revealed that majority of the respondents were in the age group of 25-34 years and maximum respondents were not aware about the main risk factors for breast cancer among women like family history, older age, nulliparity, obesity, smoking, and unhealthy diet. It was suggested that in order to decrease the spread of breast cancer among women in Kashmir valley, increasing consciousness about breast cancer is important.

A study on the location of the Pei River (浿水) in the Treatise on Joseon in the Records of the Shiji
Authors:   The Academy of Real Korean History, Jeong GyuCheol
Published: April 2023

Regarding the geography of ancient Korea, the location of the Pei River, which formed the border between the Western Han dynasty and the Joseon of Wiman, has long been a subject of sharp debate. This is because the Pei River is regarded as the western boundary of Gojoseon. The problem is that since the name Pei was recorded in the Records of the Shiji (史記), the course of the river has changed over time, and so various claims about its position have been presented. The theories concerning the location of the Pei River can be divided into the Korean Peninsula theories (Taedong River, Cheongcheon River, Yalu River), the Liaodong Peninsula theories (Yuni River, Hun River), and the former province of Liaoxi theories (Daling River, Luan River, Chaobai River). The theories claiming that the Pei River is either the Cheongcheon River or the Yalu River in North Korea have received the most support from domestic academia. However, the Korean Peninsula theories and the Liaodong Peninsula theories both have a problem in that the location and direction of the Pei River were not verified according to records made around the time such as the Hanshu (漢書), the Shuowen Jiezi (說文解字), and the Shuijing (水經). There was a Pei River on the border of Liaodong during the Western Han and, at that time, Liaodong appears to have been located in literature in the present-day Beijing area. Since the capital of Wiman Joseon was said to be in Changli County, Hebei Province, the Pei River recorded in the Records of the Shiji can only be a river between Beijing and Changli Count
The Existe ntialism of “New Poetry”and Kim Sooyoung
Authors:   The Academy of Real Korean History, Lee Changho
Published: April 2023

The poets of “New Poetry” published the first volume of “New Poetry” in April 1948, and in October of the same year they participated in the special edition of Sartre's existentialism in “Shincheonji”. However, there is no trace of Kim Sooyoung's official activities as a member of the same poetry association until “New City and Citizens' Chorus” was published in 1949. In the early days of the New Poetry Theory, Kim Sooyoung seems to have concentrated on studying poetry theory rather than on external activities. Because he had no basis in poetry theory, he had no personal relationship with the modernist poets, and his pride was hurt. However, Kim Sooyoung did not show such an expression until the mid and late 1960s. However, about 10 years after Park Inhwan's death, he criticized Park Inhwan's criticism and at the same time expressed his critical attitude toward the past modernist activities to the outside world. This seems to be connected with the period when Kim Sooyoung first realized the “dimension of criticism”.
Kim Sooyoung was deeply concerned with the concept of conscience, one of the central themes of Heidegger's existentialism. Park Inhwan and the New Poetry poets, on the other hand, focused on Sartre's existentialism. In particular, Heidegger's existentialism had a great influence on Kim Sooyoung's poetic worldview and became the basis for his original poetic theory called “Whole Body Poetics. Ten years after Park In-hwan's death, Kim Soo-young acquired the “level of criticism,” and on this basis he criticized the “difficult poetry” of Park In-hwan and New Poetry. Park Inhwan and the New Poetry Theory insisted on the social responsibility of literature, but Kim Sooyoung criticized this position of the New Poetry Theory. However, since Park Inhwan died in 1956, the question remains whether it is justified for Kim Sooyoung to blame Park Inhwan for the literary trend of the 1960s ten years later. Therefore, this paper will reveal new facts about Park Inhwan's cultural and artistic activities after his death. In addition, this paper points out that it is not possible to evaluate Park Inhwan properly due to the lack of data.

Purpose: This study aims to describe the profile of students' learning motivation in online learning and compare intrinsic motivation and extrinsic motivation. Furthermore, the research also seeks to examine the development of intrinsic and extrinsic motivation over time during online learning.

Design/Methodology/Approach: This survey research was conducted for mathematics learning at the Vocational High School level, involving a sample of 218 students selected by multistage random sampling technique. Questionnaires were administered periodically three times at an interval of six weeks. Data were analyzed using profile analysis.

Findings: The analysis revealed that the intrinsic and extrinsic dimensions of students' learning motivation tend to be parallel, with the intrinsic dimension being higher than the extrinsic dimension. The period of time also affects the development of students' learning motivation, both for the intrinsic and extrinsic dimensions.

Conclusion: The study highlights the importance of independent learning activities in online learning, which tend to develop and encourage the growth of internal motivation, essential for lifelong learning. Teachers are recommended to apply various learning theories in the digital era to increase students' internal and external motivation. In addition to well-designed learning materials, the effectiveness of online learning also depends on motivating interactions between instructors and students. Well-designed materials supported by a variety of communication media make online learning very beneficial.

This study focuses on determining the best possible structure of the orthosis made with FDM 3D printing technology. To produce the samples, a thermoplastic PLA material was selected that met the conditions of biodegradability, biocompatibility and non-toxicity. The samples produced were subjected to a tensile strength test and corrosion resistance.Studies based on FEM analysis were carried out using the advanced engineering software CAE - Inventor. The samples were designed in the CAD system, while the G-Code path was generated using the PrusaSlicer 2.5.0 program dedicated to the Prusa i3 MK3S+ printer, which was used to create the models. Surface morphology observations of PLA were carried out with a Zeiss SUPRA 35 scanning electron microscope (SEM). The static tensile test was performed on the Zwick/Roell z100 device based on the PN-EN ISO 527:1 standard. Electrochemical corrosion tests were carried out using the Autolab PGSTAT302N Multi BA potentiostat in Ringer solution at a temperature of 37C.The research allowed the appropriate structure of the orthosis made of PLA polymer material using 3D FDM printing technology. The static tensile test, SEM and corrosion tests confirmed the correct application of this material for the selected purpose. It was possible to determine that samples with holes of 10 mm had the highest strength properties. Due to the tensile tests, the average tensile strength of those samples was around 61 MPa. The corrosion parameters of PLA were determined using Tafel analysis.The research methodology proposed in work can be used to study other biomedical materials. The results presented can be the basis for further tests in order to search for the best orthopaedic stabiliser.The innovative part of the article are three different versions of structures intended for making orthoses used in medicine.
Culture on construction objects
Authors: Obolewicz J. , Baryłka A. , Szota M.
Published: April 2023

The purpose of this paper is to discuss the problem of culture in the workplace, which has been becoming increasingly popular recently.Culture has many meanings and synonyms in the Polish language - we can talk about good manners, rules of savoir-vivre, social etiquette, or politeness. Most people intuitively know how to behave in situations outside of work. In recent years, discussions about culture in the workplace have appeared more often. It is particularly relevant in the construction industry at a time when new forms of employment are emerging and many organisations are undergoing restructuring processes.It results in, among others, high staff turnover, the employment of more contract workers, frequent changes in the working environment, and working on different construction sites. In such cases, the direct and long-term impact of supervision on maintaining safe and cultural working conditions is increasingly limited. The responsibility should be borne by all site personnel, who should adopt an attitude of active and continuous concern for the culture and safety of their own behaviour and that of others and be personally involved in the process of developing cultural and safe attitudes on construction sites. The article defines culture and suggests its application on construction sites.Consequences include high rates of staff turnover, the need to bring in outside contractors, constant shifts in the workplace culture, and the need to work at many sites. The ability of supervision to provide a safe and satisfactory work environment, both now and in the future, is diminished under those circumstances. All construction workers should take responsibility and adopt an attitude of active and continuous concern for the culture and safety of their behaviour and that of others and be personally involved in the process of shaping cultural and safe attitudes on construction sites.The paper defines culture and proposes its use on construction sites.

Artikkelen kartlegger hvordan undervisning i skolefaget mat og helse blir gjennomført på 1.–4. trinn og belyser variasjoner og utfordringer i dagens undervisningspraksis. Datagrunnlaget består av 24 kvalitative intervjuer, 15 med mat- og helselærere og ni med skoleledere. Intervjuene ble gjennomført på 12 utvalgte praksisskoler fra alle landsdeler i Norge. Datagrunnlaget viser lærerne som underviser på 1. – 4. trinn sin kjennskap til kompetansemålene, grunnleggende ferdigheter og bruk av vurdering, samt tilgjengelighet og bruk av læremidler i faget mat og helse. Lærernes kjennskap til kompetansemålene i mat og helse etter 4. trinn varierte. Timetallet for undervisningen, elevenes kompetansenivå og det sosiale aspektet ved faget preget i hvilken grad vurdering ble anvendt som en del av undervisningen. De grunnleggende ferdighetene ser ut til å være en uutnyttet ressurs i mat- og helse undervisningen på 1.-4. trinn. Valg av læremidler i mat- og helseundervisningen på 1.–4. trinn var ofte tilfeldig. Siden lærebøker manglet, benyttet de fleste lærerne internett i søk etter oppskrifter. Noen lærere brukte læremidler beregnet for eldre elever, mens andre brukte hefter eller oppskrifter fra kommersielle utgivere eller fra andre fag.
Tourist panorama in the period of the health crisis with COVID-19: considerations for the state of Amazonas
Authors: Ferreira Rúbia Silene Alegre , Cunha Edileuza Lobato da , Cunha Paula Carolina Lobato da
Published: April 2023

Tourism is one of the economic activities that represents in itself a form of use of something that the locals have as a natural endowment, which, if well used can promote among several factors, heating of the local economy, strengthening of sectors to it directly and indirectly related, demonstration and diffusion of local cuisine, involvement of the populations living in the community where the tourist action is developed through services and products, as well as acting in the propagation of this wealth to the places of origin for the visiting tourist. Despite the establishment of the health crisis, as a result of Covid-19, a depression is established in these sectors, following what has manifested itself in virtually all sectors of the economy. Thus, the present research aims to identify the impact on the receptive tourism sector in the state of Amazonas as a result of the health crisis, of Covid-19. To respond to the objective that was proposed for the research, information was used in three specific moments: in the first, data from Observatur – Tourism Observatory of the State University of the Amazonas, to demonstrate the representativeness of tourism in the federation unit, pointing out the levels of formal jobs in the tourism sector in the period before the Covid-19 Pandemic. In the second action, the investigation was carried out in the database of AmazonasTur (State Tourism Company of Amazonas), to base the tourist panorama of the period in reference. In the third moment, we used data made available by the School of Arts Sciences and Humanities of the University of São Paulo (EACH-U SP), of the Research Group on Tourism Economics of the University of São Paulo, which also refer to the period of the pandemic. The results show that in 2020 and 2021 there was a drastic reduction in the movement of tourists to the Amazon, both in the domestic and foreign spheres. On the other hand, the formal jobs held in the subsectors of local tourism also accompanied the depression experienced worldwide in the economy, but also show that food and lodging services responded positively, when compared to others observed in the crisis period. established.

Companies that carry out simulated operations have become a serious problem facing the tax administration in Mexico. These types of companies are known as “ghost” or billing companies. Most of the time, these companies do not have employees or domicile, but they have the papers in order before the corresponding instances, such as registration with the Treasury, before the Ministry of Economy, with constitutive acts, etc., and most importantly: they have stamps to issue invoices for providing services or producing goods that they are unable to provide. They are companies that do not physically exist and are generally used to commit alleged crimes such as tax evasion, money laundering, or the diversion of public resources. The "ghost" companies by themselves do not evade taxes, launder money, nor disappear public resources, but require a whole structure of corrupt officials who design the scheme to simulate contracts to divert the money, as well as multiple operators, such as financial advisors, lawyers, notaries, accounting firms and front names who execute it in the purest style of organized crime, in addition to the collusion of authorities that

This work reports the development of an electrochemical biosensor after immobilization of the lymphocytes to detect the reaction between antibodies and specific HLA antigens present in the serum samples. A clean homemade gold electrode with voltammetric polycrystalline characteristics was used. Lymphocytes were immobilized and tested with positive and negative human serum and complements on the gold electrode. The experiments were carried out in a cell with three electrodes: working - gold, and reference - Ag/AgCl/sat. KCl and auxiliary - platinum. The cyclic voltammetric analyses of immobilized lymphocytes on the gold surface presented an anodic current equal to 1.78 μA at c.a. 0.50 V vs. Ag/AgCl/sat. KCl. The electrochemical responses of the serum (positive and negative) and complement do not show signs of oxidation or reduction in the potential range used. The electrodes with cells and positive serum showed the amplified current signal in the oxidation potential of the cells. The electrode was developed to verify the antigen-antibody reaction, present lymphocyte cells, and human serum samples. The electrode was qualitatively efficient when compared to the methods of flow cytometric analysis and complement-dependent cytotoxicity, being able to be used with operational and economic advantages.

In 2019, Brazil reached its highest level of production in tons of chicken meat, reaching the mark of 13.245 tons, and registered third place in the world market for chicken meat. In a position of such importance, it is increasingly necessary to standardize and refine the quality of meat and product offered. This project aimed to raise discussion and carry out an analysis of possible frauds regarding the loss of water in chicken carcasses frozen by dripping test, a process that aims to determine whether the meat absorbed excess water during the industrial process, if the carcasses pass the percentage of 6%, allowed by the legislation and by the Ministry of Agriculture, Livestock and Supply (MAPA), they do not follow what is proposed by the legislation. Eighteen samples of frozen chicken carcasses of three different brands were collected. The results obtained through this study indicate that better inspection and control by the Ministry of Agriculture, Livestock and Supply (MAPA) and the agencies responsible for the carcass cooling stage is necessary, given that one of the three brands analyzed was not under what is recommended by the legislation, being subject to notification and fine.

Published: April 2023

Objective: This study aims at reviewing the nursing role based on recent literature regarding patients submitted to cine coronary angiography, emphasizing arterial sheath removal procedures. Methods: This is an intuitive and narrative literature review, with a qualitative approach, using scientific articles published preferably in the last 5 years, available in full in Portuguese or English, in Scientific Electronic Library (Scielo), PubMed, and Virtual Health Library (VHL) databases. Results: Nursing professionals provide complex and essential care for the maintenance of life in patients subjected to cine coronary angiography during every moment of their hospitalization. Brazilian nurses, when trained, have the autonomy and ability to proceed with arterial sheath removal after the percutaneous endovascular procedure in the catheterization laboratory. There are new vascular closure devices that can decrease hospitalization time in femoral punction cases. However, the radial function is still associated with a lesser adverse event rate. Evidence-based practices are key in preventing iatrogenic. Final considerations: There are several ways of removing the arterial sheath and reaching hemostasis. All of them require knowledge and experience in the best ways of providing nursing care and performing techniques, aiming for the patient to have the shortest possible recovery time, without increasing the risk to which he is subjected.

Investigations were carried out with the Salicornia neei Lag plant, evaluating the biotechnological potential in the synthesis of lipids, starting with the histochemical location in the tissues of the stem and leaf structures, observing the intense coloration of the oil droplets present in the cells, which were stained black or dark blue, in both structures. In this study, the content of total lipids were evaluated, in addition to evaluating their potential to antioxidant activities. The total lipids of the root and leaf showed higher values corresponding to approximately 10,06% and 5.67%, respectively, and the stem 3.07%. The studies carried out also demonstrated high antioxidant activity in the root, stem and leaf, allowing the application of Salicornia neei in the food industry and as a candidate for the pharmaceutical area.

Water, an essential substance for the existence and survival of the most diverse forms of life, may become scarce in this century, becoming as precious as oil. However, despite having a sufficient volume for the supply of fresh water, suitable for the consumption of the population, its geographic layout is disproportionately presented, being adversity, due to the non-uniformity of the distribution. As a result, countries with more than 40% of the world's population already exceed the supply of this water resource, and it is predicted that by 2025, there will be a 50% reduction in the per capita water supply, affecting various fields, such as agriculture, where it plays an important role in food security. The water used in the agricultural field has the purpose of growing fresh produce, sustaining livestock, cooling crops, controlling frost, and irrigation, which corresponds to almost 65% of freshwater withdrawals in the world. In this context, the present work aims to evaluate the problems related to the use of water in agriculture and the solutions that can be implemented.

The five articles included in issue of Tanzania Zamani vary widely in terms of themes, periodisation and geographical specificity. Three of them cover differing themes on the colonial and post-colonial history of Tanzania. Of the remaining two articles, one analyses the history of the topical phenomenon of oil politics in Nigeria. Although this article focusses exclusively on an area that is far removed geographically from the official cast of the Tanzania Zamani journal, the issues it explores are clearly relevant to the history of Africa in general, as further clarified below. The fifth article presents an aspect of the archaeology of rock art in central Tanzania. The editorial team considers this diversity of themes and geographical coverage to be a good opportunity for readers to gain access to a wide range of interesting historical issues within a single journal issue.
