Abstract. Aerosol particles form in the atmosphere by clustering of certain atmospheric vapors. After growing to larger particles by condensation of low volatile gases, they can affect the Earth’s climate directly by scattering light and indirectly by acting as cloud condensation nuclei. Observations of low-volatility aerosol precursor gases have been reported around the world but longer-term measurement series and any Arctic data sets showing seasonal variation are close to non-existent. In here, we present ~7 months of aerosol precursor gas measurements performed with the nitrate based chemical ionization mass spectrometer (CI-APi-TOF). We deployed our measurements ~150 km North of the Arctic Circle at the continental Finnish sub-Arctic field station, SMEAR I, located in Värriö strict nature reserve. We report concentration measurements of the most common new particle formation related compounds; sulfuric acid (SA), methane sulfonic acid (MSA), iodic acid (IA) and a total concentration of highly oxygenated organic compounds (HOMs). At this remote measurement site, SA is originated both from anthropogenic and biological sources and has a clear diurnal cycle but no significant seasonal variation. MSA shows a more distinct seasonal cycle with concentrations peaking in the summer. Of the measured compounds, iodic acid concentrations are the most stable throughout the measurement period, except in April, when the concentration of IA is significantly higher than during the rest of the year. Otherwise, IA has almost identical daily maximum concentrations in spring, summer and autumn, and on new particle formation event or non-event days. HOMs are abundant during the summer months and low in winter months. Due to the low winter concentrations and their high correlation with ambient air temperature, we suggest that most of HOMs are products of biogenic emissions, most probably monoterpene oxidation products. New particle formation events at SMEAR I happen under relatively low temperatures with a fast temperature rise in the morning followed by decreasing relative humidity during the day. The ozone concentrations are on average ~10 ppbv higher on NPF days than non-event days. During NPF days, we have on average higher SA concentration peaking at noon, higher MSA concentrations in the afternoon and slightly higher IA concentration than during non-event days. All together, these are the first long term measurements of aerosol forming vapors from the SMEAR I in the sub-arctic region, and the results help us to understand atmospheric chemical processes and aerosol formation in the rapidly changing Arctic.
Direct dating of overprinting fluid systems in the Martabe epithermal gold deposit using highly retentive alunite
Authors: Muston Jack , Forster Marnie , Vasegh Davood , Alderton Conrad , Crispin Shawn , Lister Gordon
Published: September 2021

Abstract. The Martabe deposits in Sumatra, Indonesia formed in a shallow crustal epithermal environment (200–350 °C) associated with mafic intrusions, usually recognised in domes, adjacent to an active right-lateral wrench system. Ten samples containing alunite were collected for high-resolution geochronology, to determine if overprinting fluid systems could be recognised by dating alunite separates. The heating time for each step was chosen to ensure reasonable uniformity in terms of the incremental percentage of 39Ar gas release during each of many steps, allowing age spectra to be analysed using the method of asymptotes and limits. Several distinct growth events could be recognised. In addition, each sample was subjected to ultra-high-vacuum (UHV) furnace step-heating, and 39Ar diffusion experiments conducted at the same time as 40Ar/39Ar geochronology, to determine the argon retentivity of the mineral grains being analysed. The heating schedule ensured Arrhenius data uniformly populated the inverse temperature axis, with sufficient detail to allow the application of the Fundamental Asymmetry Principle (FAP) during analysis of the Arrhenius spectrum. Results show activation energies between 370–660 kJ/mol. Application of Dodson’s recursion determines that closure temperatures would range from 400–560 °C for a cooling rate of 20 °C/Ma, which is higher than any possible temperature to be expected in the natural system. This gives confidence that the ages represent growth during periods of active fluid movement and alteration, since the deposit formed at temperatures < 200 °C at a depth of < 2 km. We conclude that gold in the Purnama pit was the result of fluid rock interactions during very short-lived mineral growth episodes at ~ 2.25 and ~2.00 Ma.

Authors: Cheng Kai-Yuan , Harris Lucas M. , Sun Yong Qiang
Published: September 2021

Abstract. Container technology provides a pathway to facilitate easy access to unified modeling systems and opens opportunities for collaborative model development and interactive learning. In this paper, we present the implementation of software containers for the System for High‐resolution prediction on Earth‐to‐Local Domains (SHiELD), a unified atmospheric model for weather-to-seasonal prediction. The containerized SHiELD is cross-platform and easy to install. Flexibility of the containerized SHiELD is demonstrated as it can be configured as a global, a global-nest, and a regional model. Bitwise reproducibility is achieved on various x86 systems tested in this study. Performance and scalability of the containerized SHiELD are evaluated and discussed.
Malaysia COVID-19 Governmental Response

Published: September 2021

The International Health Regulations (2005) are legally binding on 196 States Parties, Including all WHO Member States. The IHR aims to keep the world informed about public health risks, through committing all signatories to cooperate together in combating any future “illness or medical condition, irrespective of origin or source, that presents or could present significant harm to humans.” Under IHR, countries agreed to strengthen their public health capacities and notify the WHO of any such illness in their populations. The WHO would be the centralized body for all countries facing a health threat, with the power to declare a “public health emergency of international concern,” issue recommendations, and work with countries to tackle a crisis. Although, with the sudden and rapid spread of COVID-19 in the world, many countries varied in implementing the WHO guidelines and health recommendations. While some countries followed the WHO guidelines, others imposed travel restrictions against the WHO’s recommendations. Some refused to share their data with the organization. Others banned the export of medical equipment, even in the face of global shortages. The UN Compliance Research group will focus during the current cycle on analyzing the compliance of the WHO member states to the organizations guidelines during the COVID-19 pandemic.

Authors: A. Sahan , KA. Erman , E. Ertekin
Published: September 2021

El objetivo de este estudio es determinar el efecto de los métodos de práctica variable en el tenis de los adultos en la ejecución del golpe de fondo. Veintidós alumnos iniciantes universitarios participaron voluntariamente de dicho estudio (edades: 22±3,4). Los sujetos fueron asignados a cada uno de los dos grupos de manera aleatoria: Grupo Constante (N=11) y Grupo Variable (N=11). El Grupo Constante practicó servicio, volea y golpes de fondo planos en cada una de las sesiones de entrenamiento. El Grupo Variable practicó servicio, volea y golpes de fondo planos junto con golpes de fondo liftados y cortados en cada una de las sesiones de entrenamiento. Se programaron sesiones de dos horas, dos veces por semana, con un total de once semanas de entrenamiento. Se aplicó una Prueba de Destrezas Tenísticas (TST, por sus siglas en inglés) a todos los sujetos por medio de pruebas anteriores y posteriores. Los resultados demostraron que una metodología de enseñanza variable para los golpes de fondo puede incrementar la habilidad de los jugadores iniciantes e intermedios para aprender las variaciones de estos golpes, más que la práctica constante.

Authors: Avilés Jiménez Oscar Mauricio
Published: September 2021

En el presente artículo se intenta reflexionar acerca de las competencias docentes que son necesarias para convertir a estos “actores” en configuradores de escenarios de formación profesional prolíficos, mediante el uso de proyectos y las buenas prácticas promovidas por el Project Management Institute – PMI®, de manera que, desde esa posición, sean los promotores de experiencias prácticas que incorporen esos saberes y experiencias colectivas en una nueva cultura de trabajo basada en proyectos. También, se vincula el enfoque por competencias desde la perspectiva del desempeño efectivo y eficiente, y que no dejan de ser el resultado de la recopilación de prácticas desarrolladas por profesionales con elevados niveles de desempeño en todas las industrias y que son abordadas con integralidad mediante el denominado “triángulo del talento” que considera el conjunto de conocimientos técnicos, el liderazgo y análisis de negocios y estrategia. De ahí la importancia de que los docentes desarrollen competencias en Dirección de Proyectos, ya que fortalecerán definitivamente el abordaje de cualquier resultado o producto académico, más allá de la disciplina, con gestos tan básicos y fundamentales que podrían ir desde el definir claramente el “alcance” de cada proyecto hasta una oportuna gestión de plazos o cumplimiento de los tiempos previstos.

Interpretation is very necessary because everyone expresses their thoughts by conveying a series of sentences which sometimes cannot be understood clearly without being followed by explanatory sentences. Interpretation of the Qur'an plays a role in helping humans grasp the secrets of Allah s.w.t and the universe, both visible and hidden. Proper interpretation is needed to understand the Qur'an properly and correctly, it requires proper interpretation so that to achieve this purpose, it is necessary to have a good mastery of the methodology of interpretation. The science of interpretation continues to grow and the number of books of interpretation continues to grow in various styles. The scholars of later commentary then sorted the books based on the method of writing into four forms of interpretation, namely: the Tahlili, ijmaii, Muqarin and Mawdhu'i methods. This paper describes some of these interpretation methods and explains the strengths and weaknesses of each method.

Political Science at the LSE: A History of the Department of Government, from the Webbs to COVID
Authors: Bannerman Gordon
Published: September 2021

This monograph traces the emergence and evolution of the LSE Government Department from 1895 to 2020, focusing on the personalities that guided the development of the Department, the social and political contexts the Department existed within, its research agenda and course structure, and the location of the Department in British politics. It also charts the evolution of the discipline of political science in Britain itself. The volume is divided chronologically into four chapters, each covering roughly similar time periods in the Departments’ history and focused on the events that shaped it: personalities, events, and location. Key themes are the development of political science in Britain, the impact of location on the LSE Government Department, the professionalisation of academia in Britain, and the microcosm the Department presents of British political life during each time period. The conflicts between progressive and conservative forces is a recurring theme which helps to link the internal dynamics of theDepartment with the wider social and political contexts that occurred from the beginning of the School to its 125th anniversary. The volume uses detailed archival research, particularly in the early chapters, as well as over thirty interviews with a range of individual with unique perspectives on the Department. These include current and former faculty and students (ranging from academics such as Christopher Hood and Tony Travers to graduates who have subsequently become politicians, such as Anneliese Dodds, Shadow Chancellor of the Exchequer), as well as others with strong links to the Department, such as Meghnad Desai, Baron Desai and Andrew Bailey, Bank of England Governor. This monograph offers a wealth of insights on the history of political science not only at the LSE, but in British academia more broadly. It speaks to a wide historical and social science audience concerned with Fabian and socialist history, the history of politics and education, and the development of British political science. Of course, it will also appeal to more immediate audiences, such as prospective and current students, alumni and others throughout the wider LSE community. As a history of the LSE, as well as of the development of British higher education, it serves as both a specific case study and a general representative of wider trends within universities during the twentieth century. A unique feature of this monograph is that it represents the collective efforts of students from the LSE Government Department (including undergraduate, MSc and PhD), who worked under the leadership of Dr Gordon Bannerman (British Historian) and Professor Cheryl Schonhardt-Bailey (Head of Government Department). This unusual collaboration has enabled a richer array of perspectives on the history of the Department, but has also brought the monograph to life with personal ties to the Department itself.

Técnicas e instrumentos para recoger datos del hecho social educativo
Authors:   Universidad Central del Ecuador, Castillo Bustos Marcelo Remigio
Published: September 2021

This paper presents reflections about the use of techniques and tools used to collect data from the educational social fact, which is understood as a social fact in its broadest meaning and sense. The research was developed framed in the qualitative paradigm, reason why are used the methods of analysis, synthesis, hermeneutics, holistic and dialectic. This has been done with the purpose of understanding the object of study and enabling a better application of techniques and instruments in the development of contextualized researches in the socio-educational field. It is revealed that despite having several epistemological approaches that guide the construction of knowledge, qualitative research emerges as the only possibility to achieve this purpose, based on the lived experience of the researcher in the reality investigated. Therefore, the nature of the research, the object of study, the initial reference frame, the context in which it is being investigated, the objectives and the methodological design that will govern the research process must be taken into account, in order to select the techniques and instruments of the data compilation in the educational social fact since it is energized by the relationships and interrelationships between human beings. Keywords: educational social facts, techniques, instruments, data.

This is a case report of hair plucking and alopecia in a flock of sheep in Zaria. Appearance of alopecia and hair pulling was noticed in an institutional sheep farm consisting of Balami, Uda and Yankasa breeds aged between 3-48 months. This was noticed over a period of 1 month in a total of 15 animals consisting of 9 ewes and 6 rams. Physical observations revealed alopecia. Blood samples and skin scrapings of the animals were negative for haemo- and ectoparasites, and faecal sample examinations were also negative. The feed analysis confirmed the correct nutrient requirement were compounded, but the feed consistency was observed to be too fine. Hay and/or pasture was not provided as required by the animals, hence, nutritional deficit was suspected. The finely ground feed was replaced with a coarse form and hay supplied ad libitum. The problem abated and the bare skin patches returned to normal in 4weeks after the diet was adjusted.  Feeding of these species of animals concentrates diets of fine particle and inadequate forage or hay could have negative effects on animal health and performance.

This study was conducted to evaluate haematological and biochemical parameters of haemogregarine-infected (h-infected) and non-infected African hinge-back tortoises in Ibadan, Nigeria. Blood samples were collected from 120 tortoises, of which 70 were Kinixys belliana and 50 were K. homeana. Stained thin smears were examined for haemogregarines using light microscope. Haematological and biochemical analyses were carried out following standard procedures. A total of 91(75.83 %) tortoises were positive for haemogregarines. Significantly (P<0.05) lower values of haematocrit (23.92 %), haemoglobin (5.21g/dl) and mean corpuscular haemoglobin concentration (MCHC) (21.78 %) were recorded for h-infected tortoises with haematocrit (33.29 %), haemoglobin (8.31g/dl) and MCHC (24.96 %). Higher values of white blood cells (WBC) (7.26 x 109/L) and lymphocytes (2.71x109/L), were observed in h-infected than non-infected with WBC (5.58 x 109/L) and lymphocytes (2.15x109/L). Higher values of haematocrit and haemaglobin were recorded for K. Homeana.  Males had higher haematocrit (27.27 %) and WBC (7.09 x 109/L) than females with haematocrit (24.35 %) and WBC (6.93 x 109/L). Females had higher MCHC, haemoglobin and calcium values than males.The lower values of haematocrit, haemoglobin and MCHC obtained for h-infected tortoises were expected since haemogregarines are usually found intra-erythrocytic in their host thereby destroying affected erythrocytes and causing a decrease in haematocrit value. Higher WBC counts in h-infected tortoises is typical in diseased conditions. The higher level of calcium in female tortoises is due to their reproductive cycle especially vitellogenesis and egg formation. Hypo-proteinaemia recorded in h- infected tortoises was attributed to parasitism. It is concluded that majority of haematological and biochemical analytes showed considerable variations with level of infection status, species and gender.

Staphylococcal infections and salmonellosis are important food-borne diseases affecting both humans and animals, and the spread of antibiotic resistant bacteria to humans through the consumption of animal food products remains a challenge. To determine the occurrence and antimicrobial susceptibility pattern of Staphylococcus aureus and Salmonella in fresh milk and milk products sold in Zaria and environs, Kaduna State, Nigeria, ninety samples were purchased comprising of 49 pasteurized milk, 20 ghee (Clarified butter) and 21 fresh milk samples in Zaria. The Samples were pre-enriched before plating on a suitable selective media. Biochemical and Sugar fermentation tests were used to detect S. aureus and Salmonella isolates; also, antimicrobial susceptibility test was carried out on positive isolates. The overall prevalence of S. aureus and Salmonella spp. in fresh milk and milk products (pasteurized milk and ghee) were 31.1% (28/90) and 6.7% (6/90), respectively. Higher prevalence of S. aureus was found in fresh milk (38.1%) than in ghee (35%) and pasteurized milk (26.5%). Also, a higher prevalence of Salmonella organism was found in fresh milk (9.5%) than in pasteurized milk (6.1%) and ghee (5%). Positive iso­lates of S. aureus showed the highest percentage of antibiotic resistance to oxacillin (100%), then tetracycline (64%) and vancomycin (57.1%), while positive iso­lates of Salmonella showed oxacillin (100%) and vancomycin (100%), followed by tetracycline (33.3%). Most of the isolates displayed resistance to more than three (3) different classes of antimicrobials, indicating multi-drug resistance. Therefore, there is a need for education and public awareness regarding hygienic processing, handling and storage of fresh milk and milk products; thus, the abuse and indiscriminate use of antibiotics in animals should be discouraged.

In a study to compare the durability of commonly used stains (Giemsa, Leishman, Wright, Eosin, Nigrosin and Gentian violet) for exfoliative vaginal cytology, vaginal smear was obtained from eleven apparently healthy West African Dwarf (WAD) female Goats and processed according to standard technique. Scores (0-3) were given on four parameters namely background of smears, overall staining pattern, cytoplasmic staining and nuclear staining. Quality index one (QI-I) was calculated from the ratio of score achieved to the maximum score possible (12), immediately post staining while quality index–II (QI-II) was obtained 35 days after. Calculation for durability index (DI) was self-derived and equalled to ratio of QI-II to QI-I. The data were presented as mean ± SEM. Multinomial logistic regression model was generated for the QI-I and QI-II using durability index as reference category. Giemsa, Leishman and Wright stains were more durable than others with their mean DI values significantly (P < 0.05) higher than Gentian violet, Nigrosin and Eosin.The model showed 89.2% overall model accuracy for the multinomial logistic regression model and 81.5% for the multinomial Bayes Naïve regression model. In conclusion, Giemsa, Leishman and Wright stains were more reliable and durable for exfoliative vaginal cytology compared to the other stains.

Mineral mining activities with environmental pollution in Nigeria resulted in lead intoxication in humans and livestock. The likelihood of lead contamination of the environment from non-mining sources may exist in Maiduguri, Borno state, Nigeria. The study was carried out to evaluate the bioaccumulation of lead in extensively reared local scavenger chickens-LSC (Gallus gallusdomesticus) in Maiduguri. Two hundred samples each of the liver, kidney, intestine, muscle and blood were tested for lead using standard methods in toxicologic evaluation. There were significant (p<0.05) variations in lead levels in the kidney, liver, muscle, intestine and blood of local scavenger chickens. The highest mean lead level (17.0±12.0µg/kg) was observed in the liver, and the lowest leadlevel (4.0±7.0µg/kg) was in the blood. No significant (p>0.05) sex differences existed in the frequency of lead detection. Mean lead level in the liver of males was significantly (p<0.05) higher than that of females with the highest and lowest mean lead levels occurring in the liver and kidney of male chickens, respectively. The highest lead level detected was 414 µg/kg; in the kidney of a female LSC. It was therefore concluded that environmental pollution with lead may be detected in LSCthat bioaccumulate lead; with the liver having the highest affinity.
