Proper Control Measures Research Articles

Overview of tuberculosis in Animals in Nigeria

Tuberculosis of animal origin is currently in the increase, especially in the developing countries like Nigeria where animals and man share microenvironment together coupled with lack of proper control measures. The disease due to Mycobacterium bovis has zoonotic implication. Systematic methodology was adopted where peer-reviewed, scholarly journals in Scopus, PubMed, Google search engines were used. The articles used were on studies in Nigeria and elsewhere and that were published in Nigeria and other parts of the world. It is therefore important to have adequate control programmes, proper food hygienic practices and collaborations between Veterinary and Human Medical Personnel in order to control and later eradicate the disease. The objective of this manuscript was to review the work of earlier workers on tuberculosis in animals and to a certain extent its impact on humans. There is also the need to educate the populace on the dangers of the disease in both human and animals.

Risk Prioritization for Failure Modes in Mining Railcars

Railway transportation systems are generally used to transport minerals from large-scale mines. Any failure in the railcar components may cause delays or even catastrophic derailment accidents. Failure mode and effect analysis (FMEA) is an effective tool for the risk assessment of mechanical systems. This method is an appropriate approach to identify the critical failure modes and provide proper control measures to reduce the level of risk. This research aims to propose an approach to identify and prioritize the failure modes based on their importance degree. To achieve this, the analytical hierarchy process (AHP) is used along with the FMEA. To compensate for the scarcities of the conventional FMEA in using the linguistic variables, the proposed approach is developed under the fuzzy environment. The proposed approach was applied in a case study, a rolling stock operated in an iron ore mine located in Sweden. The results of this study are helpful to identify not only the most important failure modes but also the most serious and critical ones.

Groundwater Modelling in Urban Development to Achieve Sustainability of Groundwater Resources: A Case Study of Semarang City, Indonesia

Since 1900, Semarang City has been meeting its industrial water needs by pumping groundwater through its underlying aquifers. The trend toward exploiting groundwater resources has driven the number of deep wells and their production capacity to increase, and therefore leads to the water table to drop from time to time, which has been marked as one of the primary causes of land subsidence there. The main aim of the current study was to numerically model the temporal and spatial evolution of groundwater table under excess abstraction so that a groundwater management strategy can be accordingly drawn up for ensuing the sustainability of groundwater resources in the future. A series of numerical simulations were carried out to take into account hydrogeological data, artificial and natural discharges of deep wells, and boundary effects in Semarang City. The groundwater modeling is calibrated under two flow conditions of the steady state from 1970 to 1990 and the transient state from 1990 to 2005 for six observation wells distributed in Semarang City. Four scenarios that reflect potential management strategies were developed, and then their effectiveness was systematically investigated. The results of our study indicate that the implementation of proper groundwater control management and measure is able to restore the groundwater level to rise back in Semarang City, and in turn achieve the sustainability of groundwater resources.

Quantification of the impact of traffic incidents on speed reduction: A causal inference based approach

This paper designs a systemic framework to quantify speed reduction induced by traffic incidents using a causal inference framework. The results can provide a reference to traffic managers for evaluating incident severities, thus take proper control measures after the incident in order not to underestimate or overestimate the negative impact. A two-phase scheme is proposed, including impacted region determination and speed reduction quantification. We first propose a Frame Region (FR) method, based on the shockwave propagation, to determine the spatiotemporal impacted region (SIR) using speed map. It is worth-noting that we design a statistical experiment to prove the rationality of congestion threshold selection. Secondly, we introduce a causal inference method for identifying the matched freeway segments. The traffic condition of finally matched freeway segments can be served as non-incident traffic condition of the incident occurred location, which contributes to quantifying the incident impact on speed reduction. We further demonstrate the proposed method in a case study by taking advantage of an incident record and related real freeway speed data in China. An interesting observation is that, along with the freeway segments away from the incident location, the congestion duration time of different freeway segments firstly rises and then decreases. The case study also illustrates the impact of incident on speed lasts almost 3 h and the congestion caused by the incident spreads 11 km, while the average causal effect of incident on all the impacted freeway segments is 42.3 km/h.

Molecular detection of zoonotic filarioids in Culex spp. from Portugal.

To investigate the role of dipterans in the transmission of Onchocerca lupi and other zoonotic filarioids, samples were collected from different sites in Algarve, southern Portugal, morphologically identified and molecularly tested for filarioids. Culex sp. (72.8%) represented the predominant genus followed by Culicoides sp. (11.8%), Ochlerotatus sp. (9.7%), Culiseta sp. (4.5%), Aedes sp. (0.9%) and Anopheles sp. (0.3%). Nineteen (2.8%) specimens scored positive for filarioids, with Culex pipiens quinquefasciatus (2%) positive for Dirofilaria immitis (1.4%), Dirofilaria repens, Acanthocheilonema reconditum, Onchocerca lupi, unidentified species of Filarioidea (0.2%, each) and Onchocercidae (0.6%). Additionally, Culiseta longiareolata (6.5%), Ochlerotatus caspius (3%) and Culex laticinctus (0.2%) scored positive for unidentified Onchocercidae, A. reconditum and for O. lupi, respectively. This is the first report of the occurrence of DNA of O. lupi, D. repens and A. reconditum in Culex spp. in Portugal. Information regarding the vectors and the pathogens they transmit may help to adopt proper prophylactic and control measures.

A Case Study of Oil Spill Trajectory Forecast Model for Effective Clean Up

Oil spills near the shore is an important environmental problem. The oil spill has to be contained in the early stages of the accident which otherwise would spread rapidly making it hard to control. The oil gets weathered affecting marine life and can get into the food chain and cause ecological distress. It also affects port and harbour activities. The after effects of the spill are mostly irreversible, so it is essential to follow proper control measures. It is essential to establish the spill forecast and movement for necessary prevention and mitigation measures. To do this, oil spill trajectory forecast models need to develop, that helps to provide the action plans to control the spill. A hydrodynamic simulation is carried out for the Ennore 2017 Chennai oil spill of India and corresponding trajectory analysis is performed. The results of the simulation will aid for effective cleanup measures to be followed in the region.

Effects of air pollution on monumental buildings in India: An overview.

Recent advancements in environmental monitoring and analysis have created public and institutional awareness on the social and health impacts of air pollution at public places of tourists' attraction. Monuments stand as the celebrated remnants of bygone representations in the social and cultural tradition of any civilised state. India, being one of the oldest and live civilisations, owns numerous places of historical evidences in the form of both constructed museums and living monuments such as temples and palaces. Continuous exposure to the emission of gaseous and particulate pollutants has made remarkable evidences of damage to the artefacts and monumental structures located in major cities of the world. The aim of this study is to present an overview of the scientific attempts pertaining to the evaluation of impacts of air pollution and other meteorological changes on the historical monuments in India in the context of the global scenario. It is observed that seasonal fluctuations in the outdoor climate and increased human activities in the vicinity of the museums have plausible impacts on the immediate changes in the indoor air quality. The variations in the outdoor air quality are greatly affected by the traffic emissions and industrial emissions, while the indoor air quality is mostly affected by the improper ventilation and lack of proper control measures. The study provides strategies for developing air quality standards for museum environment and proposes a few technical and administrative solutions to improve the air quality for indoor museums as well as outdoor monuments.

Farm use of calcium hydroxide as an effective barrier against pathogens

Livestock farming is affected by the occurrence of infectious diseases, but outbreaks can be prevented by proper sanitary control measures. Calcium hydroxide (Ca(OH)2), commonly called slaked lime, powder is traditionally used as a disinfectant to prevent infectious diseases in livestock. Since Ca(OH)2 can inactivate a wide variety of pathogens, has a small environmental impact, does not require a disinfection tank (i.e., can be spread directly on the ground) and is produced inexpensively worldwide, it is used for the prevention of epidemics on farms worldwide. Water is essential for the strong alkalinity that underlies its disinfecting effect, but it is unknown how much water is required under field conditions. In addition, Ca(OH)2 reacts with carbon dioxide in the environment, reducing its pH, but it is unclear how long its degradation takes under actual field use. Thus, we measured the water adsorption ability of Ca(OH)2-based disinfectants and its relation to disinfectant activity, as assessed by colony counts and live/dead staining and observation. We found that 15–20% (w/w) water in Ca(OH)2 was necessary for disinfection to occur in practice. Moreover, we found that the pH of Ca(OH)2 decreased within about two weeks to one month under actual use in practical conditions and lost its ability to disinfect. We further showed that granules prepared from Ca(OH)2 and zeolite maintained high alkalinity more than twice as long as calcium powder. These findings will help to establish a suitable method of applying Ca(OH)2 to protect farms from infectious diseases.

Lung Function Impairment and Workplace Control Measures among Marble Stone Carvers in Sa-Kyin Village, Madayar Township, Myanmar

Introduction: Marble rocks, composed of dust containing calcium carbonate and silica particles, predispose to a higher prevalence of occupational lung diseases. This study aimed to assess workplace control measures and lung function impairment among marble stone carvers.
 Methods: A cross-sectional descriptive study was conducted among 120 marble stone carvers in Sa-Kyin Village, Madayar Township in May 2019. Information about existing control measures in the workplace was assessed using a pre-tested structured questionnaire and participants’ lung function using spirometry. Respirable dust measurements in twelve randomly selected workers were performed by personal air sampling pumps.
 Results: It was found that 9.2% of marble stone carvers used disposable or cloth masks throughout the working time, but no one was found using appropriate devices like respirators. No one reported about regular medical checkup and provision of health education at the workplaces. Spirometry testing showed 55.8% had lung function impairment. Concentrations of respirable dust ranged from 7.19 to 10.13 mg/m3, significantly higher than the recommended Threshold Limit Value (3 mg/m3). In multivariable logistic regression analysis, development of lung function impairment was associated with age [adjusted Odds Ratio (aOR) = 2.84; 95% CI = 1.02,7.91] and use of face mask (aOR = 0.11; 95% CI = 0.01,0.91).
 Conclusion: The working environment was found dusty, and a significant proportion of workers had lung function impairment. It is essential to adopt proper dust control measures in stone carving workplaces. Preventive measures like medical surveillance and health education program are vital to reduce the burdens from occupational lung diseases.

Maxillofacial Prosthodontics during a pandemic

I am writing this as we have just started 2021. What a year 2020 has been! Social distancing restrictions, dental office closures, limited access to PPE still occurring in certain areas, and very strict and slow reopening rules for dental clinics worldwide as we now tackle the 2nd or 3rd wave of the pandemic. Last year has brought many challenges to all of us. Maxillofacial prosthodontists in particular have been in a very unique position during this pandemic compared to some of our dental colleagues: with many of us being affiliated to hospitals meant that we were often deemed front line essential workers. We witnessed the struggles of our patients as many head and neck surgeries were being postponed or canceled due to the risk of contamination or due to of lack of ventilators. We needed to contact colleagues to refer patients that were suddenly unable to cross borders to continue their ongoing care. We found new ways to teach dental students and prosthodontics residents remotely while becoming pioneers in adapting dental offices to the new reality of covid-19. What we have learned during this last year, is that unfortunately nobody was prepared for a pandemic. It has shown us how fragile our entire system was, but also how resilient and adaptable we could be. Many prosthodontics organizations embraced social distancing and created faster communication pathways to their members to provide them with timely information on how to best navigate this change of events. They shared ideas on how to facilitate teledentistry, discussed how to install proper infection control measures, helped members navigate business interruptions, and compared international guidelines regarding various stages of reopening. Witnessing this sharing of material and cooperation between organizations that had not normally communicated with one another has been heartwarming. This pandemic has had devastating impacts worldwide, but it has also shown us how we could adapt to new changes quickly and allowed us to learn many lessons along the way. We continued to perform research to improve the quality of life of our patients as seen in the article: Evaluation of xerostomia and effect of maxillofacial prosthesis use on mouth dryness in head and neck tumor patients, and developed new teaching methods for taking advantage of the capabilities of 3D scanning and rendering. These new techniques often translated into innovations in practice as we embraced this new digital world, as described in Three-dimensional printing immediate surgical obturator before maxillectomy: A pilot study. Both articles are published in our 2021 issue of the International Journal of Maxillofacial Prosthetics. I am confident we will come out of this pandemic stronger as we re-engineer the future of maxillofacial prosthodontics so that our profession not only survives these challenges, but thrives from everything we have learned and accomplished.

Efficacy of Infection Control Measures in Managing Outbreaks of Multidrug-Resistant Organisms in Burn Units.

Multidrug-resistant organisms (MDROs) pose a significant threat to severe burn victims and represents a clear epidemic hazard in burn units. Several infection control measures have been implemented to control and manage the outbreaks of MDRO. The efficiency of those measures, however, remains controversial and an area of debate. A systematic review was conducted to evaluate the efficacy of infection control measures and the necessity of closing burn units in dealing with MDRO outbreaks. Peer-reviewed articles were identified using PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases, focusing on infection control measures to manage MDRO outbreaks in burn units. Twenty-one studies that reported MDRO outbreaks in burn units met the inclusion criteria. The outbreaks were successfully controlled with interventions in 17 units (81%), partially controlled in 1 unit (4.7%), and uncontrolled in 3 units (14.3%). Infection control measures were implemented by screening patient (19 units), screening health care worker (17 units), obtaining environmental cultures (16 units), providing ongoing staff education (13 units), cohort or isolation (17 units), preemptive barrier precautions (10 units), improving hand hygiene (15 units), and enhanced cleaning and environmental disinfection (17 units). Closure of burn units occurred in 8 units, with outbreaks controlled in 6 of the units (75%). The reasons for unit closure include decontamination (4 units; 50%), outbreak investigation (1 unit; 12.5%), and uncontrolled outbreaks (3 units; 37.5%). The incidence of infection was significantly decreased in 4 units after the closure but rose again after reopening in 1 of the units. In 3 units, the spread was halted by other control measures, including change of hydrotherapy facilities, identification of staff transmission, and unit structure remodeling. Proper infection control measures play an important role in managing MDRO outbreaks in burn units. Temporary closure of burn units may be necessary to control the spread of nosocomial, and this option should be considered when other measures are ineffective.

A Surprisingly Non-attractiveness of Commercial Poison Baits to Newly Established Population of White-Footed Ant, Technomyrmex brunneus (Hymenoptera: Formicidae), in a Remote Island of Japan

The white-footed ant, Technomyrmex brunneus, was newly introduced and established in a remote island of Japan and has caused unacceptable damage to the daily life of residents. To establish proper control measures, the present study investigated whether T. brunneus is effectively attracted to commercially available poison baits used to exterminate common household pest ants and the Argentine ant in Japan. Cafeteria experiments using three types of nontoxic baits and eight types of commercial poison baits for ants were conducted in the field, and the attractiveness was compared among the baits. The liquid poison bait “Arimetsu,” which consists of 42.6% water, 55.4% sugar, and 2.0% borate, and nontoxic 10% (w/v) sucrose water showed the highest attractiveness. On the other hand, other commercial poison baits were not as attractive. Therefore, sucrose liquid is the most effective attractive component to use in poison baits for T. brunneus.

Evaluating the potential of soil management to reduce the effect of Fusarium oxysporum f. sp. cubense in banana (Musa AAA)

Fusarium oxysporum f. sp. cubense (Foc) causes Fusarium wilt in banana (Musa AAA). Foc Race 1 devastated the subgroup Gros Michel during the first half of the twentieth century. The Gros Michel was largely replaced by the resistant subgroup Cavendish in the 1950s. However, in the 1980s, Foc Tropical Race 4 started to spread affecting Cavendish bananas. No proper control measures have been found to deal with the disease. This paper re-takes an important research line from the 1950s to evaluate the potential of soil management for Fusarium wilt management. The role of soil properties on Fusarium wilt in bananas was studied in two greenhouse experiments. It was evaluated whether the influence of two main soil properties (pH and N) on Fusarium wilt is similar for Race 1 and Tropical Race 4. Two soil pH levels (lower than 5.2 and higher than 6.0) respectively ensured through acidification and liming; and three levels of N (ammonium nitrate, 33.5% N) weekly doses (low:0 N g, medium: 0.08 N g and high: 0.25 N g per plant) were achieved. The first experiment in Costa Rica confirmed the earlier results about the influence of soil pH and nitrogen on Fusarium wilt (Race 1) on Gros Michel bananas. The second experiment in The Netherlands evaluated the influence of pH and N on interactions between Foc (both Race 1 and Tropical Race 4) and Cavendish bananas. Results in both experiments showed that soil pH affected crop development and the disease. Besides, the interaction of the lower pH x the higher N accelerated the infection and reduced plant development. As such, the results showed that soil management has the potential to reduce the impacts of Fusarium wilt while dealing with Race 1 and Tropical Race 4 although it requires confirmation and further evaluation under field conditions.

BACKGROUND Pseudomonas aeruginosa is an opportunistic pathogen involved in a variety of nosocomial infections like pneumonia, bacteraemia, wound infection and urinary tract infection. It is also involved in infections of rigorous burns and infections in immunocompromised persons. This study was undertaken to determine the prevalence and antibiotic susceptibility patterns of pathogenic P. aeruginosa isolated from a variety of clinical specimens in a tertiary care hospital of Jamshedpur, Jharkhand, India. METHODS Pseudomonas aeruginosa was identified using standard methods from various clinical samples collected over a period of seven months. This was a descriptive cross-sectional study which was approved by the ethical committee. The study was conducted from January 2019 to January 2020 in the Department of Microbiology at MGM Medical College, Jamshedpur, Jharkhand, India. This hospital has ICUs, one emergency ward, surgical & medical wards and Out-Patient Departments. RESULTS Our study showed the prevalence of P. aeruginosa during the study period from January 2019 to January 2020 in the Department of Microbiology at MGM Medical College, Jamshedpur, Jharkhand, India. A total of 1389 clinical samples were aerobically cultured, out of which 758 (54.6 %) yielded significant growth and the rest 630 (45.4 %) samples were either sterile or showed non-significant growth. From 758 positive growth samples, 161 (21.20 %) P. aeruginosa were isolated CONCLUSIONS The high prevalence of P. aeruginosa as an opportunistic nosocomial pathogen and high frequency of antimicrobial resistance among the clinical isolates demand regular monitoring of antibiogram of P. aeruginosa isolates with proper implementation of antimicrobial policy. Antibiotics should be used appropriately with care. Antimicrobial therapy should not be started unless there is clear evidence of infection and infection to be handled with proper infection control measures.

Staphylococcus aureus in Intensive Pig Production in South Africa: Antibiotic Resistance, Virulence Determinants, and Clonality.

Although Staphylococcus aureus is a major threat to the veterinary, agricultural, and public health sectors because of its zoonotic potential, studies on its molecular characterisation in intensive animal production are rare. We phenotypically and genotypically characterised antibiotic-resistant S. aureus in intensive pig production in South Africa, using the farm-to-fork approach. Samples (n = 461) were collected from the farm, transport vehicles, and the abattoir using the World Health Organisation on Integrated Surveillance of Antimicrobial Resistance (WHO-AGISAR) sampling protocol. Bacteria were isolated using selective media and identified using biochemical tests and polymerase chain reaction (PCR). Phenotypic resistance was determined using the disk diffusion method. Selected resistance and virulence genes were investigated using PCR. Clonality among the isolates was determined using the repetitive element sequence-PCR. In all, 333 presumptive staphylococcal isolates were obtained, with 141/333 (42.3%) identified as staphylococci biochemically. Ninety-seven (97; 68.8%) were confirmed as S. aureus using PCR, 52.6% of which were identified as methicillin-resistant S. aureus (MRSA) through the mecA gene. All the 97 S. aureus isolates (100%) were resistant to at least one of the antibiotics tested, with the highest resistance observed against erythromycin and clindamycin (84.50% each), and the lowest observed against amikacin (2.10%); 82.47% (80/97) were multidrug-resistant with an average multiple antibiotic resistance index of 0.50. Most of the phenotypically resistant isolates carried at least one of the corresponding resistance genes tested, ermC being the most detected. hla was the most detected virulence gene (38.14%) and etb was the least (1.03%). Genetic fingerprinting revealed diverse MRSA isolates along the farm-to-fork continuum, the major REP types consisting of isolates from different sources suggesting a potential transmission along the continuum. Resistance to antibiotics used as growth promoters was evidenced by the high prevalence of MDR isolates with elevated multiple antibiotic resistance indices >0.2, specifically at the farm, indicating exposure to high antibiotic use environments, necessitating antibiotic stewardship and proper infection control measures in pig husbandry and intensive pig production.

COVID-19 Outbreak: A Renaissance in Dentistry

The novel coronavirus which originated from the city of Wuhan, China, in late 2019 has put the entire human race at risk. The widespread destruction caused by novel coronavirus has led the World Health Organization to declare it a pandemic disease on March 11, 2020. Health workers, especially the dentist, are at great risk of getting infected due to the nature of dental procedure which requires close proximity to the patient's mouth. The risk of cross-infection from dental settings is high, so proper infection control measures are required to restrict the spread of infection. This article focuses on the effect of COVID-19 on dental fraternity, its management in dental setup to restrict cross-contamination, and information on various guidelines issued to render their services in COVID-19 situation.

The detoxification enzymes activity profile in susceptible Aedes and Culex mosquitoes

The status of susceptible mosquito is important for monitoring and managing insecticide resistance in field population. The purpose of this study is to profile the differential expression level of enzymatic activities of metabolic enzymes exhibited in the mosquito species of Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus from the susceptible strain. The fourth instar larvae of each strain were subjected to biochemical assay. The total protein content and enzymatic activities of Glutathione S-transferase (GST), α-esterase (α-est), β-esterase (β-est) Cytochrome P450 (Cyt P450) and Acetylcholinesterase (AChE) from each mosquito strains were elucidated. Significant difference (P<0.05) was detected between the total protein content between all species of susceptible strain mosquitoes. One-way ANOVA showed that the specific enzymatic activities of GST, α-est and Cyt P450 of all test mosquitoes were significantly different upon comparison with each species (P<0.05). The mean of enzymatic activities of insensitive AChE showed no significant difference upon comparison with each other (P>0.05). The enzymatic activities of β-est shows no significant difference between Ae. aegypti and Cx. quinquefasciatus mosquitoes (P>0.05) but the enzymatic activity of β-est in Ae. albopictus manifested significant difference upon comparison with the enzymatic activities of the other two test species (P<0.05). The results obtained may provide more information about the enzymatic activities of metabolic enzymes in Ae. aegypti, Ae. albopictus and Cx. quinquefasciatus mosquitoes which might be beneficial for public sector for the application of proper vector control measures.

Clincal implications of orthodontic patients during covid -19 pandemic: A review article

Introduction: Corona-virus 2019 also known as COVID-19 is highly contagious and rapidly growing disease. A severe acute respiratory condition syndrome SARS-COV-2 affected more than 200 countries. The quick advancing of the pandemic has gripped the entire community making it as Public Health Emergency. Dentists, including Orthodontist are at a very high risk of acquiring and transmission of infection. The transmission mainly occurs through respiratory tract, aerosol and droplets. Clinical symptoms mainly vary from mild, moderate and severe type of sickness. So, the objective of this review is to give an expansive overview of the clinical implications of orthodontic patients during COVID-19 pandemic and to increase awareness about the strategies for infection control and prevention. Methods: A comprehensive literature from orthodontic relevant sources and information was searched with the help of Pubmed, Medline, Google scholar, Scopus, World Health Organization and various National Orthodontic associations. Results: Due to rapidly evolving nature of disease, this review mainly emphasizes on the strategies for infection control measures, minimizing aerosol production, restricting appointments to emergencies only during the outbreak. Conclusion: During the outbreak, electric orthodontic treatment should be suspended and should only be resumed when allowed by the state, local health regulatory authorities. Emergency orthodontic treatment should be followed with the help of proper strict control measures and guidelines. Minimizing personal contact and aerosol production are keys to prevent contamination with the orthodontic settings.

Purification of air from volatile organic compounds by countercurrent liquid gas mass transfer absorption process

Nowadays environmental sustainability is a fundamental requirement for the development of any process. In this regard, European Union applied directives on emission reduction commitments. In such circumstances, it is mandatory for industries or facilities to adopt proper pollution control measures to meet the requirements. The absorption process can be a simple, safe, regenerative and recovery technique, selective for the species. The aim of this work is to study the purification process of polluted air containing volatile organic compounds by absorption towers. The evaluation of the feasibility of the process and the effects of operative conditions on the efficiency will be discussed. Ethyl acetate was selected as a representative volatile organic compound chemical model. We experimentally purified air containing this pollutant at different concentrations by absorption with pure water, changing the temperature and the ratio between water and air flowrate. We investigated the effect of different packagings and their height using two columns: the first one with Sulzer rings and the second one with Raschig structured packaging. Finally, the effect of recycled solvent in the absorption process was considered. PRO/II software simulator enabled a steady-state simulation of the tests obtaining an excellent fitting of the experimental data.
