The main objective of this Austria Fire Futures study is to develop a unique and innovative concept containing new sets of fire risk hotspot maps at highest spatial resolution under various climate change scenarios and integrate novel insights on local fuel types into forest and forest fire risk models, including new variables such as morphology and recreational activities. To generate such maps on a local scale, fire hazard modeling is necessary to identify endangered forest types in combination with topographic effects. Furthermore, recent fire events in the Austrian Alps show that social aspects, particularly the hiking tourism, are paid too little attention to.Based on the above motivation, we believe that an innovative and improved fire risk hotspot mapping is the fundament for all further forest- and wildfire prevention and hence needs to be seen as an indispensable tool for an integrated fire management (prevention, suppression, post fire measures) while substantially contributing to mitigating climate change as well as minimizing damage to ecosystems, their services, and people.The study will improve our understanding of fire-vulnerable forest areas that may shift over time and space given the underlying climate and fuel assumptions. This will allow experts, practitioners, and the interested public to take a look into the future in order to comprehend and derive solid short-/medium-/and long-term recommendations for fire resilient and sustainable forest management and fire emergency planning.
The choice of present-day climate forcing can significantly affect modelled future and past Antarctic Ice Sheet evolution
Authors: Wirths Christian , Sutter Johannes , Stocker Thomas
Published: February 2023

Model simulations of past and future Antarctic ice sheet (AIS) evolution depend on the applied climatic forcing. To model the present and future Antarctic ice sheet, several different forcings from regional climate models are available. It is therefore critical to understand the influence and the resulting model differences and uncertainties associated with the choice of present-day reference forcing.  

We apply present-day climatic forcings from regional models (RACMO2.3p2, MAR3.10, HIRHAM5 and COSMO-CLM2) combined with climate anomalies from a global climate model (HadGEM2-ES). With this setup, we investigate the future evolution of the AIS under the RCP2.6, RCP4.5 and RCP8.5 scenarios using the Parallel Ice Sheet Model (PISM). We find substantial differences in the future evolution of the AIS depending on the choice of the present-day reference field even under an extreme scenario such as RCP8.5. We discuss the influence of those forcing choices on the projected future AIS dynamics and sea-level contribution, considering a variety of ice sheet model parameterizations. 

With this analysis, we aim to gain a better understanding of the role of climate forcing choices and parameterization-induced uncertainties of sea-level rise projections. 

 
From flume to field: using analogue modelling to delve into uncertainty in our interpretations of volcanic bedforms and what they tell us about deadly hazards

Published: February 2023

Pyroclastic density currents (PDCs) are density-driven flows of gas, ash and rock generated during explosive volcanic eruptions, or by the collapse of volcanic lava domes. They can reach temperatures of >500 °C and are highly mobile, with the ability to travel at speeds of >200 m/s and to scale obstacles hundreds of metres high. PDCs are a devastating volcanic hazard and have killed >90 000 people since 1600 AD1; understanding their behaviour is an important aspect of volcanic disaster risk reduction. Because of their extreme nature, PDCs are difficult to observe and quantify in real time. Volcanologists therefore use field studies and modelling techniques to investigate their dynamics.As PDCs travel they progressively deposit ignimbrite, a poorly sorted volcanic rock typically rich in pumice and ash. Ignimbrites commonly display a variety of bedforms and stratigraphic architecture; such architecture can be interpreted to unpick the behaviour of the original PDC, and of the evolution of the eruption that created it. However, there is considerable uncertainty involved in ignimbrite bedform interpretation, due to the potential for complexity (such as cryptic bypass, erosion, and hybrid processes) and also due to fundamental gaps in our knowledge of the physical properties of PDCs.Our work uses analogue modelling of gas-fluidised, dense, granular currents in a laboratory flume together with examples from the field to explore what the dynamics of experimental PDCs (and their resultant bedforms) can tell us about our interpretations of real-world volcanic stratigraphy. The examples presented examine a range of bedforms and processes, including the impact of fluidisation and grainsize on PDC mobility and bedform morphology, the influence of moisture on cohesivity and bedform preservation, and the implications of grading in volcanic stratigraphy. The significant challenges in quantifying the sedimentation of ignimbrites are discussed. This work seeks to improve field interpretations of volcanic bedforms and contribute to the development of volcano risk models. 1: Auker et al. (2013) J Appl.

Published: February 2023

Our research team has been working on a map of geodiversity and biodiversity of the Canaima National Park in Venezuela for several years. Already at the beginning of the work, we asked ourselves whether and to what extent geodiversity affects the level of biodiversity.Geodiversity maps are synthetic maps, but if one of the components of the factors plays a greater role, we are able to immediately capture it. In the case of NP. Canaima has the greatest impact on the summary geodiversity map of the terrain - we have Tepui (eg Mt Roraima) here, outstanding Mesa-type mountains.Having some information on the abundance of animal and plant species, we tried to link them with the intensity of geodiversity.

The asteroid (16) Psyche is the target of the NASA Psyche mission, where the magnetometer is one of the three science instruments on board. Its purpose is to prove whether the asteroid formed from the core of a differentiated planetesimal. The magnetometer will measure the magnetic field at different distances from the asteroid in order to detect any remanent magnetization, where a magnetic moment larger than 2×10^14 Am2 could imply that the body once generated a core dynamo, and therefore formed as an igneous differentiation.The Psyche spacecraft carries two three-axis fluxgate magnetometers mounted on a fixed boom at 2.15m and 1.45m, respectively, which provide redundancy and gradiometer capabilities to compensate for spacecraft-generated magnetic fields. The magnetometers will be powered on early in the initial checkout phase and remain on throughout cruise and orbital operations and producing 50 vectors per second. The in-flight temperature of the magnetometers is expected to span a large range, therefore an extensive calibration program has been carried out in order to characterize the instruments and prove the performance pre-flight.
Changes in river temperature, discharge and heat flux based on new observational data for Yenisei basin and modeling

Published: February 2023

River temperature plays an important role in numerous biological and ecological processes within the Yenisei River basin and it is very sensitive to changes in climatic characteristics and anthropogenic disturbances. Water temperature and river discharge characterize heat or energy flux, which is important in northern latitudes for river freeze-up and ice break-up processes and thermal riverbank erosion. The changes in heat flux in river estuary can also significantly impact various biophysical processes in coastal ocean waters.We use new water temperature data and river discharge records for 12 observational gauges in the Yenisei River basin to analyze changes in water temperature and heat flux from upstream to downstream over 1950-2018. Preliminary results show significant increases for most gauges in maximum annual water temperature as well as in 10-days mean water temperature during May-June and September-October. There were no significant changes in river temperature during July-August unless the gauges were impacted by reservoir regulations. The river heat flux has significantly increased in central and northern parts of the Yenisei basin and decreased in the south, mainly due to discharge variability.The gridded hydrological Water Balance Model (WBM) developed at the University of New Hampshire, that takes into account various anthropogenic activities, was used to simulate river discharge and water temperature for entire Yenisei basin with a 5 minute spatial resolution river network using several climate reanalysis products (MERRA2, ERA5 and NCEP-NCAR).  The modeled results were verified with observational data and simulations using the MERRA2 climate drivers demonstrated the best match with observations (Nash-Sutcliffe model efficiencies coefficients were greater than 0.5 for both river temperature and discharge). Maps of modeled changes in runoff, river temperature and heat flux show the opposite changes in the southern and northern parts of Yenisei basin. The model simulations correspond well with observational data even for heavily disturbed river reaches. For example, they show unfrozen water with positive temperatures during the winter below large dams and reservoirs.       The WBM was also applied to project changes in water temperature, discharge and heat flux up to 2100 for several SSPs and GCMs from CMIP6. In spite of heterogenous projected changes in these parameters across Yenisei basin, significant increases in discharge and heat flux to the Arctic Ocean are expected.
Long-term plant-microbe interactions weaken the rhizosphere priming effect in tundra systems
Authors: Bouskill Nicholas , Riley Bill , Li Zhen , Mekonnen Zelalem
Published: February 2023

Ecosystem priming is a critical process contributing to the carbon balance of tundra soils. On one hand, plant exudation of labile organic compounds can stimulate microbial activity inducing the decomposition of more complex organic matter, resulting in soil carbon loss. On the other hand, the efficient processing of plant exudates, and stabilization of microbial necromass in soils, can increase soil carbon stocks, reducing CO2 emissions to the atmosphere. The divergence between positive and negative priming depends on ecosystem stoichiometry, microbial trait distribution, climate, and non-linear interactions between plants and microbial activity. Here we employ a mechanistic model, ecosys, to examine the role of microbial trait distribution and plant-microbe interactions in determining priming effects on tundra soil carbon stocks. The ecosys model represents distinct functional guilds of bacteria (e.g., heterotrophic decomposers, nitrifiers) and fungi (e.g., mycorrhizae and saprotrophs), and the diversity within, as a function of their traits, including carbon use efficiency (CUE). We examine the role of priming in short- and long-term experiments. We initially benchmarked the ecosys model to well-studied sites in the North American Arctic and explore how diversity in microbial CUE regulates soil carbon stocks under different priming conditions (e.g., a single application of labile carbon vs. semi-continuous exudation conditions) over the course of one year. We then scale up these simulations to the whole of Alaska and examine how plant-microbe interactions alter the priming effect over centennial time scales, with and without warming. We generally observed the attenuation of the priming effect contingent upon elevated nutrient concentrations under warming, which reduced plant exudation to soils. We will discuss these results, and how microbial traits influence the long-term balance of soil carbon in tundra ecosystems.  
Refining linear interpolation of water level data with the use of autoregressive models
Authors: Niedzielski Tomasz , Halicki Michal
Published: February 2023

Although linear interpolation is the simplest method for inputing hydrograph data, there are evidences for its efficiency in hydrology. It works well at edges of no-data gaps because the inputation is limited by bounds. However, it does not reconstruct the hydrologic variability of water levels recorded before and after a no-data gap. In this paper, we combine linear interpolation with autoregressive models in order to account for both controlling bounds as well as anticipating irregular variation of hydrograph. We check the performance of this approach using hourly water level time series collected between 2016 and 2022 at 28 gauges located in the Odra/Oder River basin in Poland. For the purpose of validation, we produce missing data gaps artificially, using the moving window approach. By considering root mean square errors (RMSE) of interpolation as a function of gap length and investigating differences between these RMSE values computed using linear interpolation with/without autoregression, we identify cases in which the postulated approach refines purely linear interpolation. Initial studies suggest that the combination of methods reveals slightly better skills than the linear interpolation itself for short no-data gaps, the length of which does not exceed 24 hours.The research has been conducted in frame of the project no. 2020/38/E/ST10/00295 within the Sonata BIS programme of the National Science Centre, Poland.

RESUMO: A destinação de recursos para a manutenção da malha viária nacional mostra-se desproporcional à quantidade de veículos colocados diariamente nas vias, o que resulta em pavimentos em péssimas condições. Assim, faz-se necessária a adoção de Sistemas de Gerência de Pavimentos Urbanos compostos por métodos de avaliação práticos para a obtenção das condições das vias. Este trabalho tem como objetivo analisar o emprego do método das Matrizes de Valores Fixos comparando-o com outros métodos objetivo e subjetivo na avaliação da condição de pavimentos flexíveis urbanos. Para isso, foi utilizado um banco de dados de avaliações subjetivas e objetivas executadas nos anos de 2017 e 2018 na malha viária de um campus universitário. Para verificar a aplicabilidade do índice foram realizadas análises gráficas e testes de correlação entre os resultados obtidos por meio das Matrizes de Valores Fixos, do Valor de Serventia Atual e do Pavement Condition Index. A partir das primeiras comparações foi verificado que a matriz é um método menos rigoroso que os demais. Nos testes de correlação, os altos índices obtidos indicaram uma mesma tendência entre os métodos, além de que há coerência nos índices obtidos pela matriz. Concluiu-se que o método da Matriz de Valores Fixos pode ser utilizado na avaliação das condições de pavimentos flexíveis urbanos, tendo em vista sua praticidade de aplicação e obtenção de resultados coerentes e satisfatórios.
ABSTRACT: The allocation of resources for the maintenance of the national road network is disproportionate to the number of vehicles placed on the roads daily, which results in pavements in poor condition. Thus, it is necessary to adopt Urban Pavement Management Systems composed of practical assessment methods to obtain road conditions. This study aims to analyze the use of the Fixed Values Matrices method comparing it with other objective and subjective methods in in evaluating the condition of urban flexible pavements. For this, a database of subjective and objective assessments carried out in 2017 and 2018 on the road networks of a university campus was used. To verify the applicability of the index, graphical analyzes and correlation tests were performed between the results obtained through the Fixed Value Matrices, the Present Serviceability Rating, and the Pavement Condition Index. From the first comparisons, it was verified that the matrix is a less rigorous method than the others. In the correlation tests, the high indices obtained indicated the same trend between the methods, in addition to the consistency of the indices obtained by the matrix. It was concluded that the Fixed Values Matrix method can be used to evaluate the conditions of urban flexible pavements, given its practicality of application and obtaining coherent and satisfactory results.

Digital transformation implies some organizational changes when using digital
technologies and new business models to improve efficiency. With another definition, if we
try to compare the concepts of "Digital transformation" and "Digitalization", then digital
transformation includes changing the company's current business model, its strategy and
values, ways of interaction with customers and suppliers, using digital technologies. At the
same time, if the digitalization is based on some technology, the transformation should be
directed towards the customer, in the conditions of the introduction and use of automated
systems. Clarification of these approaches is of agenda importance for the transition to
digital transformation of the business environment, to which this article is dedicated.
The article presents the approaches, stages, levels of digital business transformation
of the business environment, the role of new business models in the conditions of the
digital economy, as well as studies the changes in the digitalization index of the business
and the issues of introduction and use of automated systems.

Identification of issues impeding the development of border communities, assessment of drawbacks of the state policy implemented in this sphere and the development of the socio-economic concept based on it have always been and remain the main prerequisite for the maximum demonstration of real economic potential of any state. Currently, the uneven development of the regions is becoming more and more problematic together with all accompanying risks such as population emigration, economic activity decrease, urbanization, population ageing and regional GDP decrease. In the context of even development of border communities, the factual assessment of factors hindering the progress of those communities is of utmost importance. Based on this, in the current Armenian reality the proposal of practical ways of socioeconomic development and ensuring their applicability remain topical more than ever before.
Possibilities and challenges of unblocking of Armenia by Turkey

In general, it is accepted that mutually beneficial economic relations are the best prescription for solving any conflict. At first glance, the Armenian-Turkish relations should also be considered within the framework of the same logic, but everything is not so clearcut... The recent history of relations between Turkey and Armenia began in 1991 after the collapse of the USSR and the declaration of independence of the Republic of Armenia. In 1991 on December 16, Turkey recognized the independence of Armenia, but the countries have not established diplomatic relations until now. At the root of the hostile sentiments between Armenia and Turkey are the well-known historical facts: the denial of the Armenian Genocide of 1915, the occupation of Armenian historical territories, as well as the closing of the border in the interest of a third country, Azerbaijan. Nevertheless, the Armenian-Turkish trade never stopped during the blockade. At the same time, it's no secret that the actual volume of Turkish-Armenian trade is uncontrollable, because most of it is carried out indirectly through the mediation of third countries. Turkey keeps Armenia in a blockade and closes the entry of Armenian goods to the Turkish markets, that is, not only the border is closed, but also the entry of Armenian goods to the market, instead, it does not cause any problems when importing Turkish goods to Armenia through the territory of Georgia.

The NovoSorb® Biodegradable Temporising Matrix (BTM) (PolyNovo Biomaterials Pty Ltd, Port Melbourne, Victoria, Australia) is a fully synthetic dermal matrix that can be used to reconstruct complex wounds. It consists of a 2mm-thick NovoSorb® biodegradable polyurethane open-cell foam covered by a non-biodegradable scaling member. Application involves a two-stage procedure. In the first stage, BTM is laid onto a clean wound bed, and in the second stage, the sealing membrane is removed and a split skin graft is applied to the neo-dermis. BTM has been used to reconstruct deep dermal and full-thickness burns, necrotising fasciitis, and free flap donor sites in the early phase. This review documents examples from a comprehensive series of cases in which BTM was applied to a wide range of complex wounds, ranging from hand and fingertip injury, to Dupuytren’s surgery, chronic ulcers, post excision of cutaneous malignancies, and hidradenitis suppurativa. BTM can be applied to a wide range of complex wounds which may otherwise require a more challenging reconstruction. It should be considered an important adjunct to the reconstructive ladder.

Background: The results of recent studies regarding the efficacy of Negative Pressure Wound Therapy (NPWT) for the prevention of sternal wound infection (SWI) after adult cardiac surgery are not conclusive. Methods: Data were collected from patients who were operated upon at the GVM Care & Research group in Italy from 2013 to 2021; all patients who required treatment for sternotomy wound infection with Negative Pressure Wound Therapy (NPWT) through WaterLily™ system (Eurosets, Medolla, MO, Italy) were selected. We compared the preoperative risk characteristics, and particularly those that were most strongly associated with possible dehiscence of the wound. A statistical analysis was performed for comparison of the groups. Results: Out of the total 40,267 patients who underwent cardiac surgery with extracorporeal circulation within this time frame, 1,483 (3.68%) required NPWT, including 690 (46.52%) in the HOME group and 793 (53.47%) in the HOSPITAL group (p =0.76). Thirty-nine (5.65%) patients in the HOME group and 37 (4.66%) in the HOSPITAL group required re-treatment for re-dehiscence after secondary closure (p =0.79). Conclusions: The use of a WaterLily™ system (Eurosets, Medolla, MO, Italy) was safe and effective for the treatment of sternotomy wounds with superficial and deep infections and was associated with a low rate of dehiscence, even when used with discharged and managed outpatient patients.

Mesh suture was initially developed and investigated to overcome suture pull-through in hernia repair. It has a large area compared to standard suture which distributes the load in tissue, reducing stress at the suture/tissue interface and preventing suture from cutting through tissue or the mesh. This report describes our early experience using the new T-line® mesh (Deep Blue Medical Advances, Durham, NC, USA) in patients with incisional and primary ventral hernia repairs. This is a descriptive, retrospective study in 18 patients who underwent abdominal wall repair with T-Line® mesh from November 2020 to November 2021 in three academic centers. T-Line® is a novel moderate-weight macroporous, polypropylene mesh with extensions that are 29 times the cross-sectional area of #0 polypropylene suture. They can be sewn into fascia to anchor the mesh with no need for suture tackers or other devices to fixate the mesh. The median age of the patients was 56.5 years (range 25-83) and the median BMI was 31.7 kg/m2 (range 23.6-51). Twelve patients (66.7%) had primary hernias, and 11 (61.1%) had a recurrent hernia. The median defect area was 117.5 cm2 (range 4-390) and the median mesh area was 449.5 cm2 (range 130-600). The mesh position was onlay in 16 cases (88.9%) and sublay in 2 cases (11.1%). The median operative time was 247 minutes (range 104-395). The median length of stay was six days (range 0-21) with no significant in-hospital complications. One patient had a surgical site infection (5.5%) and two patients developed seromas (11.1%). There were no early hernia recurrences with a median follow-up of 28 days (range 8-307). The T-Line® mesh was shown to be safe and effective for patients with ventral hernia in the short term.
A Novel Distal Biceps Rupture Repair Technique Utilizing a Biocomposite Scaffold

Published: February 2023

Distal biceps tendon ruptures are uncommon injuries that have a re-rupture rate of 1.2% - 6%. In severe traumatic injuries or chronic injuries, a distal biceps tendon repair may require augmentation due to insufficient tissue quality. Unsuccessful treatment of these injuries can result in the loss of approximately 40% of supination strength and 30% of elbow flexion strength. There has been a growing interest in biologic augmentation in orthopedic surgery, and its incorporation into distal biceps tendon repairs has increased as well. Established bio-inductive implants and dermal allografts have been shown to be of benefit; however, these biologics have drawbacks such as failure to incorporate at time of implantation, lack of structural strength, and technical difficulty of implantation. The BioBrace® (ConMed, New Haven, CT) is a bio-inductive, biocomposite scaffold that is composed of highly porous type I collagen and bio-resorbable poly (L-Lactide) (PLLA) microfilaments. It can be used in conjunction with distal biceps tendon repair or reconstruction. It has the advantage of providing strength to the augmented repair at time zero of implantation, while also demonstrating the ability to induce new organized tissue growth throughout its resorptive phase. We describe a technique to successfully augment a distal biceps tendon repair using the BioBrace®.

Design of International Airport Hybrid Renewable Energy System
Authors: Minja Monyiachix , Mushi Aviti
Published: February 2023

This paper presents the design and simulation of a hybrid renewable energy system utilizing solar and wind energy sources with a backup generator. The demand for reliable electric energy in support of investments in large social and economic development activities such as airport operations has been an agenda worldwide. In Tanzania, Mwanza International Airport (MIA) expects to consume about 18 MVA of electric power annually to support its operations for the next 25 years. About 78-80% of the world's commercial energy comes from fossil fuels. Non-renewable fuels and other negative effects contribute to global warming through greenhouse gas emissions and carbon dioxide emissions. Additionally, most centralized conventional power generation methods require transmission systems, adding complexity and poor power quality. Therefore, the proposal to use a mixed-coupled hybrid renewable energy source to power the airport is necessary. The energy mix considered is solar photovoltaic (PV), wind, diesel generator and a battery. There is an average solar irradiation of 5.38 kWh/m2 and a wind speed average of 4.20 m/s that could be converted to electricity by installing a 10-kW wind turbine (this is enough to generate power for MIA). The diesel generator and the battery designed at 140 kVA and 400 Ah, respectively, take the intermittency. The project will be in operation for 25 years; hence its costs are reasonable, and the justification is the potentiality of harvesting that estimated energy output of 18 MVA, which will meet the load for MIA.

We solve in closed-form the optimal investment strategies in equity and VIX derivatives in a stochastic volatility model with jumps. Our framework includes both complete market and incomplete market cases, when diffusive risk, volatility risk and jump risk are present. VIX derivatives allow for direct exposure to volatility risk compared to equity derivatives. Based on the closed-form formulas, we explicitly determine the portfolio improvements brought by the inclusion of the VIX derivatives and establish that it is theoretically positive. This justifies the economic intuition and observed demand for VIX derivatives in a portfolio management setting. Numerical examples illustrate the results.

The low motivation of parents to send their children to madrasas is directly related to the current issue of education there. One of the reasons for this condition is that the acceptance of new students has not gone as expected. This is because the new student admissions policy is not implemented properly and the management of the student admissions program is not managed properly. In order to maximize the effectiveness of admissions, this study examines and analyzes the impact of implementing new admissions policies on admissions program management. Census and descriptive methods are combined in this research. At MTs Al-Mu'awanah and MTs Nurul Hidayatul Iman, a sample of 51 teachers was taken from the general population. The data analysis method is a statistical path analysis model. Field studies and documentation studies are used to collect data. The value of tcount > ttable, namely = tcount 2.2190 > ttable = 2.0117 obtained from the results of hypothesis testing with path analysis. This shows that H0 is rejected and H1 is accepted. This shows that the management of the new student admissions program has a positive and significant effect on the implementation variable of the new student admissions policy in order to realize the effectiveness of student admissions. Important research findings have been revealed, so it is recommended to find a solution to this problem by following steps: 1) Arranging a student admission program earlier each academic year. This is done to adjust the program to government policies through the ministry of religion. 2) Carry out more mature planning starting from determining which students will be accepted, class targets, strategies in recruiting prospective students. 3) Gathering with community leaders, religious leaders, SD/MI heads who are targeted by madrasas by going around or by holding meetings at the madrasa.

Introduction: Typhoid fever is still a very important health problem. This disease is still often found in developing countries located in tropical areas such as Indonesia and subtropical areas. Acute typhoid fever is an acute systemic infectious disease caused by the microorganism Salmonella enteric serotype typhi known as Salmonella typhi (S. typhi). Laboratory examinations to establish the diagnosis of typhoid fever in general can be checked with the Widal test and Salmonella IgG/IgM, tubex test and culture test. Several diagnostic methods are faster, easier to perform and affordable for developing countries with fairly good sensitivity and specificity, such as Widal and salmonella IgG/IgM tests, starting to be used in Indonesia. Purpose: This study was to determine the examination of Widal and salmonella IgG/IgM in patients with suspected typhoid fever.. Research Method: The type of research used was cross sectional, this research was conducted in the Laboratory of Bunda Palembang Hospital. Samples were serum/plasma of patients with suspected typhoid fever.  Results: The results showed that there were 11 patients with suspected typhoid fever who were Widal positive and then confirmed using salmonella IgG/IgM and 6 samples were diagnosed positive with typhoid fever. Data analysis using chi-square test obtained p value = 0.014. Conclusion: The conclusion of this study is that there are significant differences in the examination of Widal and salmonella IgG/IgM in patients with suspected typhoid fever

Introduction: Leukocytes are blood cellscontaining nuclei, orso-called white blood cells. Leukocytes have a role in the cellular and humoral defense of organisms against foreign substances. Some types of leukocytes or white blood cells are present in the blood. Leukocytes are generally divided into granuocytes (which have special granules) andagranulocytes (which do not have special granules). Granulocytes consist of neutrophils, eosinophils, and basophils. Agranulocytes consist of lymphocytes and monocytes. Leukocyte count examination is a routine blood test conducted  in the clinical laboratory because of the frequent request for a test to calculate the number of leukocytes. Calculate the number of leukocytes not only determinethe number ofleukocyte cells, but can also be any type of leukocyte cells. Objectives: The purpose of this study is to determine the difference in the number of leucocytes immediately and stored for 6 hours.Methods: This research method usescross sectional, this sample was taken from studentslevel 1 and 4Medical Laboratory Technologyof Health Sciences and Technology Muhammadiyah Palembang. Result: The results of this study obtained an averagecount of the number of leukocytes immediately is 6.3667 cells/μl, while the average count of the number of leukocytes stored for 6 hours is6.4667 cells/μl. Result: The results of T-test statistics showed a significant value (0,477) was higher than the alpha value of 0.05 or ρ>ɑthen Ho, receivedwhich means there is no difference in calculating the number of leukocytes immediately and stored for 6 hours. Conclusion: The conclusion of this study is that there is no difference in calculating the number of leukocytes immediately and disinced for 6 hours.

This study contributes and features the intermingling of two particular patterns during the COVID-19 pandemic and its results. On one hand, a few of the most terrible financial, educational, political and socio-psychological costs of the infection people have to pay and the management crisis is excessively borne by minimized staff. Normally, these effects haven't been covered by the overall population, their well-being and the actual costs of the infection. In this way, the pandemic has featured how chances of worldwide financial betterment matters were lessened. On the other hand, early signs show that customized ideas of 'risk management and 'flexibility' are important to understand post-emergency worldwide development plans. At an indistinguishable time, because the COVID-19 pandemic has made the general and inconsistent nature of dangers in the global financial and educational aspects, a few of the preeminent underestimated sections of the total population are being studied to be answerable for dealing with those dangers.
