Simulation Evidence on How Progression Through the Prospective Teacher Pipeline Affects Teacher Workforce Diversity
Authors: Goldhaber Dan , Mizrav Etai
Published: July 2023

There is tremendous interest among policymakers and advocates in diversifying the teacher labor market. This interest is driven at least in part by a growing body of research that points to the benefits of diverse teachers, particularly for students of color. While the diversity of the teacher workforce in the United States has increased in recent decades, it is still lags far behind the diversity of the nation’s students. To better understand the issue and what can be done about it, we simulate how varying levels of diversity at different points in the path to becoming a teacher affects the diversity of early-career teachers. Our simulations suggest that the lack of teacher diversity is due less to high school or college graduation disparities and more to the choices of college students about whether to pursue teacher preparation programs and become teachers. We also find that increases in the retention of teachers of color have relatively little impact on the diversity of the workforce: even if schools retained 100 percent of their early-career teachers of color, it would only increase workforce diversity by about 4 percentage points.
Вплив ступеня компенсації поточного видобутку вуглеводнів нагнітанням сухого газу на ефективність видобування ретроградного конденсату
Authors: Матківський С. В. , Кондрат О. Р.
Published: July 2023

Для підвищення ефективності розробки газоконденсатних родовищ із значними запасами ретроградного конденсату проведено дослідження ефективності технології підтримання пластового тиску з використанням сухого газу на основі неоднорідної цифрової тривимірної моделі. Згідно з результатами моделювання встановлено, що у випадку нагнітання сухого газу в газоконденсатний поклад знижуються питомі втрати конденсату в пласті за рахунок стабілізації та підтримання пластового тиску на вищому порівняно з розробкою на виснаження рівні. Результати моделювання свідчать про те, що завдяки впровадженню технології підтримання пластового тиску зменшується насиченість порового простору конденсатом та, відповідно, забезпечується додатковий його видобуток переважно в газовій фазі на поверхню. Зі збільшенням ступеня компенсації поточного видобутку вуглеводнів нагнітанням сухого газу підвищується накопичений видобуток конденсату та, відповідно, кінцевий коефіцієнт вуглеводневилучення. За результатами проведених розрахунків підвищення коефіцієнтів вилучення конденсату залежно від ступеня компенсації поточного видобутку вуглеводнів нагнітанням сухого газу становить: 0,5–3,57 % ; 0,75–5,01 %; 1–6,08 %; 1,25–6,93 %; 1,5–7,70 %. На основі результатів статистичного аналізу розрахункових даних визначено оптимальне значення ступеня компенсації поточного видобутку вуглеводнів нагнітанням сухого газу, яке становить 0,972. Підвищення кінцевого коефіцієнта вилучення конденсату для наведеного оптимального значення ступеня компенсації поточного видобутку вуглеводнів нагнітанням сухого газу дорівнює 5,96 %. Результати проведених досліджень свідчать про високу технологічну ефективність впровадження технологій підтримання пластового тиску про розробці газоконденсатних родовищ із значними запасами конденсату.

Published: July 2023

Насосні штанги є складовою одиницею свердловинного обладнання штангових свердловинних насосних установок і служать для передачі зворотно-поступального руху від верстата-качалки до плунжера заглибного насоса. Експлуатація насосних штанг проходить в складних умовах знакознінних навантажень розтягу/стиску, згину, тертя об внутрішню поверхню колони насосно-компресорних труб, впливу корозійно-активного середовища, відкладень асфальто-смоло-парафінових відкладень. З метою підвищення ресурсу колони насосних штанг пропонується замість сталевих використовувати штанги з полімерно-композиційних матеріалів (склопластиковий , вуглепластиковий, гібридний стрижень з двома сталевими головками). Застосування гібридних насосних штанг дає чимало економічних й експлуатаційних переваг в порівнянні зі сталевими та склопластиковими штангами Із збільшенням глибини спуску колони насосних штанг зростає навантаження на штангу, а, отже, і на з’єднання сталевої головки із полімерно-композиційним стрижнем. Вплив пружних характеристик матеріалу гібридного стрижня (параметра ортотропії, параметра зсувної податливості, величини зчеплення) та особливостей контактної взаємодії його зі сталевою головкою на величину та розподіл тиску і, як наслідок цього, на міцність та працездатність розглянутого конструктивного з'єднання має практичний інтерес при проектуванні з’єднання. Ставиться задача підвищення міцності з’єднання гібридної насосної штанги та його надійності. В роботі запропоновано використання скінченно-елементного аналізу в програмному середовищі SolidWorks методом кінцевих елементів при проектуванні оптимальної конструкції з’єднання сталевої головки з композиційним тілом гібридної насосної штанги. На основі проведеного аналізу пропонується конструкція з’єднання з циліндричною частиною сталевої головки змінної товщини, з прорізами у цій циліндричній частині у вигляді пелюсток та виконання галтелі на виході з контакту головки та стрижня штанги.
Перспективи газоносності гравігенних структур зони Красноріцького скиду Дніпровсько-Донецької западини України
Authors: Лазарук Я. Г.
Published: July 2023

В осадових товщах багатьох нафтогазоносних басейнів світу встановлено гравігенні диз’юнктивні дислокації і пов’язані з ними плікативні структури. З такими структурами пов’язані численні родовища нафти і газу. Антиклінальні підняття осадового чохла, які простягаються вздовж зони Красноріцького скиду на південному сході Дніпровсько-Донецької западини, є типовими гравігенними утвореннями. З ними пов’язані близько півтора десятка газоконденсатних родовищ. Однак, у північно-західній частині низки продуктивних структур між Євгеніївським та Борівським родовищами на ділянці довжиною майже 40 км не відкрито жодного родовища вуглеводнів. За результатами вивчення гравігенних тектонічних дислокацій зони Красноріцького скиду встановлено, що склепіння прирозломних антикліналей зміщуються в плані слідом за зміщенням самих порушень. Таке зміщення склепінь у продуктивних відкладах родовищ  може становити 0,5 км і більше. Неврахування зміщення структурних планів з глибиною може бути причиною невдач пошукового буріння в зонах гравігенних дислокацій.  Тому в подальшому рекомендоване буріння похило спрямованих свердловин з метою розкриття продуктивних пластів в апікальних частинах піднять. На ділянці Муратівського скиду за даними сейсморозвідки встановлено три підняття. Показано невідповідність форми піднять і форми порушень з позицій гравігенного тектогенезу. Дана рекомендація для уточнення структурних побудов. За результатами зіставлення геологічних матеріалів і космічних фотографій простежений зв’язок долини ріки Сіверський Донець з Муратівським скидом. Висловлено припущення, що гравігеннідугоподібні порушення, з яких складається цей скид,  відображаються в будові річкової долини дугоподібними вигинами древніх русел. За цією ознакою нами виділено ще три прогнозні складки довжиною від 2,0 до 3,5 км.  Отримані результати з прогнозування нових гравігенних структур запропоновано використати для планування сейсморозвідувальних робіт на північно-західному продовженні Муратівського скиду.

A quantum theory of electronic energy transfer in a layered nanostructure with molecular J-aggregates of polymethine dyes was proposed. An expression for the exciton-plasmon bond energy depending on various parameters of the system was given. The rate of non-radiative Fὄrster resonance energy transfer (FRET) from surface plasmon polaritons (SPPs) of a metal substrate to Frenkel excitons of J-aggregates was determined and dispersion dependences for hybrid states were obtained. It was established that the energy transfer rate can reach values of 1012–1013 s–1, and the value of the Rabi splitting is up to 100 MeV. The kinetics of the process under strong exciton-plasmon interaction was investigated. The time dependence of the energy exchange between the system components had the form of damped oscillations depending on the relaxation parameters, the Rabi frequency, and the response to resonance. In addition, the exciton FRET between two parallel monolayers of J-aggregates of polymethine dyes separated by a nanometer-thick metal film was investigated. It was found that the presence of the metal layer increases the FRET rate. The spin evolution of a pair of two triplet (T) molecules localized in the nano-cell region under the over-barrier jumps regime in a magnetic field was studied. The influence of the parameters of the two-dimensional potential on the frequency of inter-dimensional motions and the population of triplets was considered. The spin dynamics of molecular T-T pairs in the magnetic field of a ferromagnetic globular nanoparticle under free surface diffusion of a spin-carrying molecule was investigated.

The S,N-doped carbon quantum dots based on citric acid and L-cysteine were synthesized. The sizes of the synthesized carbon dots vary from 4 to 10 nm. The absorption spectrum exhibits a band with a maximum at 360 nm, as well as a shoulder at about 240–250 nm. The fluorescence band of the studied carbon dots is located in the region of 370–600 nm with a maximum at ~430 nm. The properties of the long-lived luminescence of carbon quantum dots solutions were studied. It was established that the decay of triplet states occurs as a result of a radiative phosphorescent transition and triplet–triplet annihilation. The synthesized carbon quantum dots are reviled to be the singlet oxygen sensitizers, as evidenced by the observed luminescence of molecular oxygen upon excitation of solutions in the absorption band of the carbon quantum dots. It was shown that when O23 ( )g− was added to the solution, the process of singlet–triplet annihilation develops, the efficiency of which depends on the concentrations ratio of triplet carbon quantum dots and singlet O2(1∆g) molecules. In the presence of plasmonic Ag nanoparticles, the phosphorescence of singlet oxygen is enhanced.

The development of information technology is growing so fast which has resulted in the emergence of increasingly fierce business competition. The application of information technology in the retail business can certainly help in simplifying and accelerating business processes. Toys Amanah is a family shop located on Jl. Kemandoran Pekayon RT 04/RW 023 Pekayon Jaya Village, South Bekasi District, Bekasi City, West Java Province. This shop sells a variety of toys and office stationery supplies. In its business process, this store still carries out sales transaction activities manually using receipts and notebooks for recording sales data and collecting data on goods. Therefore, in the transaction process, errors often occur in calculating the amount of money that must be paid by customers and it takes a lot of time to record reports and frequent inventory data errors that result in discrepancies between the inventory data and the physical goods. The next problem is that the store wants to give discounts to customers who often come in order to increase customer loyalty, but there is no system that can record loyal customers. In defining requirements and analyzing and designing systems for companies, data collection methods are needed by means of literature study, observation, interviews, design, implementation, and testing. For the analysis method and the concept of this information system, the unified modeling language (UML) model is used. The results of this study will be the construction of a web-based point of sale information system which is expected to be able to deal with the problems that exist in the store. This information system is made using the PHP programming language, MySQL database. With this point of sale information system, it can handle complaints experienced by the store in the process of the system running. Such as an error in the sales transaction process and data collection of goods and the length of time required to process sales reports.

Published: July 2023

Abstract: Basarang Jaya Village in Kapuas Regency, Central Kalimantan is a placement location for transmigrants from the island of Bali. Transmigration does not only move the human body, but also the culture and customs. Interactions that occur between local communities and immigrant communities will cause a shift and development of the cultural values of these communities. The physical condition of the transmigration location environment using the anjir-handil-saka concept is also very much different from the physical environment where the transmigrants originate, in the form of mountains and the sea.This raises a theoretical gap that underlies this research through a problem statement, namely how to apply the concept of traditional Balinese architecture to residential areas on the edge of anjir. This study aims to determine the application of the concept of traditional Balinese architecture in residential areas on the edge of anjir. The research approach used is a qualitative approach with a case study method.The results showed that there was an adaptation in the application of the Sanga Mandala conception to the culture of the local community and the physical conditions of the environment. Residential houses no longer consist of many masses but only one single mass. Natah is also no longer located in the madya ning madya but is spread throughout the zone surrounding residential buildings, even though the utama ning madya is still maintained as a zone for sanggah.Abstrak: Desa Basarang Jaya di Kabupaten Kapuas, Kalimantan Tengah merupakan lokasi penempatan transmigran yang berasal dari Pulau Bali. Transmigrasi tidak hanya memindahkan fisik manusianya saja tetapi juga budaya serta adat istiadatnya.

Acacia xanthophloea is a tree in the Fabaceae family with wide distribution mainly around Laikipia in Central Kenya and major parts of the Rift Valley town of Naivasha, Kenya. A number of trees under the Fabaceae family are renowned as sources of vegetable tannins for leather processing. Despite recent advances in research, locally available vegetable tanning materials have not been widely exploited in Kenya for commercial tanning purposes. This study aimed to evaluate the mechanical properties of goat leather tanned with crude extracts of Acacia xanthophloea from Naivasha, Kenya. Crude extracts of Acacia xanthophloea combined with pre-tanning and tanning procedures were used to produce leather. The commercial mimosa was used as a control. The leather tanned with crude extracts of Acacia xanthophloea had a thickness of 0.81 ± 0.11 mm, tearing strength of 37.87 ± 2.09 N, tensile strength of 27.50 ± 7.51 N/mm2, percentage elongation of 18.00 ± 6.67, grain crack of 6.19 ± 0.20 mm and grain burst of 7.10 ± 0.27 mm. The crude extracts of Acacia xanthophloea confer good tanning and give the leather a reddish tinge, whereas some mechanical properties attenuated, compare favourably with the control (mimosa). Acacia xanthophloea which is abundantly available in Kenya with scarce use can potentially be cultivated and refined as a commercial source of tannins.

Purpose: This study aimed to explore the effects of the type of mask worn during aerobic exercise on respiratory function. Methods: A total of 30 people were included in this study. The subjects were randomly assigned to two groups: the dental mask group (wearing dental masks during aerobic exercise, n=15) and the KF94 mask group (wearing KF94 masks during aerobic exercise, n=15). Aerobic exercise was performed using a sedentary cycle with eight levels of intensity control three times a week for 4 weeks. Respiratory function (forced vital capacity [FVC], forced expiratory volume in one second [FEV1], FEV1-to-FVC ratio [FEV1/FVC%], and peak expiratory flow [PEF]) was assessed using a spirometer at 0, 2, and 4 weeks. Results: A significant difference in all respiratory function parameters, including FVC, FEV1, FEV1/FVC%, and PEF, was observed between the two groups (p<.05). The change in respiratory function was not statistically significantly different between the two groups. However, a significant difference in the amount of change in PEF was observed between the two groups at 4 weeks (p<.05). Conclusion: The dental and KF94 mask groups showed increased respiratory function. However, no significant difference was observed between the two groups. Furthermore, no difference was observed in the amount of increase in respiratory function during aerobic exercise according to the mask type. Thus, we recommend wearing a dental mask that is easy to breathe during aerobic exercise.

Purpose: This study aimed to indirectly assess physical strength and muscle mass to determine the level of respiratory muscle strength in community-based older women. Methods: A total of 30 women aged 65 years or older were included in this study. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and grip strength were measured. Timed up and go test, five times sit-to-stand test (FTSST), one-minute sit-to-stand test (1MSTST), and bioelectrical impedance analysis (BIA) were performed. Subsequently, a correlation analysis was performed between the measured data and respiratory muscle strength. Results: MIP was significantly correlated with pulmonary function parameters, including FVC, FEV1, FTSST score, 1MSTST score, and body mass index (BMI) measured by BIA. MEP was significantly correlated with FEV1/FVC, FTSST score, 1MSTST score, and BMI. Conclusion: A significant correlation was observed between respiratory muscle strength and FTSST score, 1MSTST score, and BMI in community-dwelling older women. Further studies are needed to predict respiratory muscle strength levels based on leg muscle strength and BMI and to manage respiratory muscle health in community-dwelling older individuals.

Methods: This study included female students in their 20s who passed 3-5 weeks after being diagnosed with COVID-19. The subjects were assigned to experimental and control groups according to the participation period. The experimental group performed 10 min of warm-up and cool-down exercise and 30 min of diaphragmatic breathing exercise accompanied by dynamic upper extremity exercise three times per week for 4 weeks. Pulmonary function (forced vital capacity and forced expiratory volume at one second) and respiratory muscle strength (maximal expiratory pressure and maximal inspiratory pressure) were assessed using a spirometer. Cough capacity (peak expiratory flow) was assessed using a peak flow meter. Data analysis was performed using independent and paired t-tests. Results: No significant increase in pulmonary function and respiratory muscle strength was observed in both groups. However, the experimental group showed a significant increase in cough capacity and grip strength (p<.05). Conclusion: Breathing exercise accompanied by dynamic upper extremity exercise may be effective in improving cough capacity and grip strength in females in their 20s with confirmed COVID-19.
Effects of Exercise-Based Cardiac Rehabilitation During a Week-Long Hospital Stay on Lactate Levels in Patients with Acute Myocardial Infarction
Authors:   Korean Academy of Cardiorespiratory Physical Therapy, Lee Jeong-Jae
Published: July 2023

Purpose: Few studies have been conducted to examine changes in lactate levels associated with the severity of myocardial infarction during cardiac rehabilitation. Thus, this study aimed to investigate the effects of exercise-based cardiac rehabilitation on lactate levels in patients with acute myocardial infarction. Methods: A total of eight patients (7 males and 1 female, aged 64.1 ± 12.8 years) who were diagnosed with acute myocardial infarction and participated in an inpatient cardiac rehabilitation program were included in this study. Lactate levels were measured using Lactate Plus (Nova Biomedical, Rodermark, Germany), which can measure lactate levels from 0.3 to 25.0 mmol/L. Exercise intensity during the inpatient cardiac rehabilitation period was set at 40%-60% of peak oxygen uptake (peak VO2), and cardiopulmonary exercise testing and lactate level measurements were conducted before and after exercise. Normally distributed data were analyzed using paired t-tests, and non-normally distributed data were analyzed using the Wilcoxon signed-rank test. Results: VO2peak and metabolic equivalents significantly increased, and minute ventilation per unit carbon dioxide production showed a decreasing trend but not a significant decrease (p=.014, p=.02). During the one-week inpatient rehabilitation period, lactate levels at rest before exercise on the first and last days of rehabilitation significantly decreased (p=.036). Lactate levels significantly increased immediately after exercise (p=.014), while lactate levels before exercise showed a decreasing trend in all eight patients. Conclusion: In patients with acute myocardial infarction, lactate levels increased immediately after exercise-based cardiac rehabilitation, while lactate levels at rest decreased during the one-week rehabilitation period as aerobic capacity improved.
Assessing the knowledge, attitude, and practice (KAP) of parents and service providers’ perceptions on invalid vaccine doses: A study in urban slums of Bangladesh
Authors: Sultana Tahmina , Moniruzzaman Md. , Dey Sima Rani
Published: July 2023

This paper aims to assess the parental attitude, knowledge and practice regarding valid vaccination schedule of child immunization and identify the reasons for providing invalid vaccine doses. A cross-sectional, mixed-method study design was used to conduct in randomly selected urban slums of Bangladesh. Among the 456 respondents, 99.34% had good experience in vaccination services, and 95.83% believed that this service increased their children’s immunity. But only 31.36% had adequate knowledge about the number of vaccinations provided by the routine immunization program, and only 4.17 % knew about invalid vaccine doses. The parent’s knowledge level was significantly associated with mothers’ education (p-value: 0.042) and media exposure (p-value: 0.014). The immunization practice was significantly associated with the number of living children (p-value: 0.004). Majority of the respondents (96.71%) reported that no one informed them about the invalid dose of the vaccine. According to service providers the service charges, urban-living people’s mobility, NGO field staff workload, and inadequate training were the major causes of providing invalid vaccine doses in urban slums. It is recommended that service providers might engage the slum authority in immunization activity to mobilize the slum people about the vaccination program to create awareness among them and ensure valid vaccination doses.

INTRODUCTION/BACKGROUND. The paper will examine the impact of a largely unexplored variable, managerial credibility, on employees’ turnover’s intentions. The research paper aims to add value to the existing literature which has cited job satisfaction, job security, and compensation plan to be the variables that influence employees’ turnover’s intentions. Existing literature revealed three major determinants of managerial credibility, trustworthiness, competence, and good will. Moreover, to observe the relationship more closely, turnover was specified as voluntary, avoidable, and dysfunctional turnover.

METHODOLOGY. The research program uses quantitative data gathered through 326 respondents, who were employees who had been working in both private and public sector organizations in Karachi for more than a year. The respondents were contacted personally, and were asked to fill out questionnaires. For turnover intention, close-ended questionnaire based on 3-point Likert scale was used, and for managerial credibility, 5-point Likert scale was used. These variables were entered into the multiple regression models for analysis.

RESULTS. Overall the employees’ turnover’s intentions increased by 14.7% due to variance in Goodwill (reciprocal), Competence, and Trustworthiness. Furthermore, intent to turnover and the independent variables had a relationship of 39.3% between them (p<0.05). A unit increase in intent to turnover is associated with a statistically significant decrease of 44% (p<0.000) in Trustworthiness, 40% in Competence (p<0.001), and 277% in Goodwill (p<0.010).

DISCUSSION. The credibility of the manager does have an impact on the employees’ intent to turnover. Increment in the determinants of managerial credibility can decrease the employees’ intent to turnover, and potentially save the organisation from dysfunctional turnover.

CONCLUSION. The results unearthed a new variable that has an impact on the employees’ turnover’s intentions. The impact is low, but nonetheless, it is a factor that organizations should strive to nullify.

This article aims to explore the impact of economic restructuring on CO2 emissions in Vietnam during 1986 – 2020. Data in the study are collected from the World Bank and website: https://countryeconomy.com/. The study uses a Vector Auto Regression model (VAR) to analyze the effect of economic restructuring on CO2 emissions. The research results show that the ratio of value-added by agriculture industry on GDP has a negative impact on CO2 emissions in Vietnam. On the contrary, the proportion of value-added by industry and construction to GDP has an effect positive on CO2 emissions. This study contributes to enhancing knowledge about the relationship between CO2 emissions and economic restructuring which is significant to the transformation of green economy in Vietnam. Based on the research results, we propose a number of implications including: (1) The Government should consider promulgating regulations to make it easier for farmers to access credit policies for the application of Science and Technology in green production, energy saving, and change the backward production in rural areas; (2) The government should strengthen support for farmers with information about new technology products in agricultural activities such as: new methods of sustainable production, environmental protection but effective high economic; (3) The government should monitor forestry activities, contribute to improving the forest environment, and reduce environmental pollution in Vietnam; (4) The Government considers promulgating regulations on the control of vehicles/machines operating in the industrial-construction sector with large emissions in order to reduce emissions effectively.

Economic development in each country has been importantly contributed from business community, especially from small and medium enterprises (SMEs). In the context of the 4.0 technology revolution, the revolution has brought many opportunities for businesses in general, especially SMEs in particular in accessing business opportunities and the ability to apply technology in production. In addition, national trade policies are becoming important premises linking business activities of domestic enterprises and foreign markets. In this research, the authors conducted the impact of trade policies on business performance of enterprises in the context of the rapidly evolving 4.0 technology revolution. Using survey data at 190 small and medium-sized enterprises in Ho Chi Minh City, analyzed by SPSS software, the research results show that commercial policies at enterprises have not yet brought business efficiency, while other factors financial and operational experience of the enterprise has a positive or negative impact on the business performance of enterprises in Ho Chi Minh City. The study also confirmed that there is no impact of the quality of human resources and the relationship with partners on business performance. In addition, the study also suggests some policy implications to improve business performance in the context of rapid technological change nowadays.

Purpose: Sensorimotor impairment in the elderly leads to increased postural sway and plantar pressure distribution asymmetric. The plantar pressure distribution asymmetrical can cause secondary problems, such as forefoot pain, neuropathic plantar ulcers, and metatarsal stress fractures. Therefore, this study aims to examine the effect of sensorimotor training on the plantar pressure distribution symmetry in healthy elderly women. Methods: Forty healthy elderly women participated in this study and were randomly assigned to two experimental and control groups (20 people in each group). Pressure distribution was evaluated during standing with double-legs and eyes closed. The experimental group performed sensorimotor training for eight weeks, and the control group did not receive any intervention during this period. The statistical method of analysis of covariance (ANCOVA) was used to compare the results between the two groups. Results: Analysis of covariance (ANCOVA) test showed that after eight weeks of sensorimotor training, the plantar pressure distribution in the forward and backward of the right (P=0.000) and left (P=0.000) foot was balanced with a high effect size. In addition, the plantar pressure distribution symmetry of the inter-limb was balanced after eight weeks of sensorimotor training with a high effect size (P=0.015). Conclusion: Sensorimotor training by adjusting balance strategies and increasing the impulse sent from mechanical receptors cause sensorimotor integration and facilitates muscle activity. As a result, posture sway is reduced and plantar pressure distribution symmetrical.

O objetivo do presente trabalho foi o de comparar os parâmetros cinéticos da xantina desidrogenase (XD) do soro de ratos normais e de ratos protadores de sarcoma induzido por 20-metilcolantreno. Foi verificado que a XD decresce no soro dos animais portadores. A afinidade da XD para com a xantina foi semelhante no soro normal e no soro de animais com sarcoma. A inativação a 7O C é, aparentemente, de primeira ordem em relação à concentração de enzima. A atividade XD foi linear durante 60 minutos de incubação e a enzima do soro de animais com sarcoma foi mais sensível à ação de diferentes inibidores. Concluiu-se não haver diferença significante na estrutura de ambas as XD e que o decréscimo da atividade XD no soro de portadores de câncer indica uma baixa na concentração de enzima no soro sangüíneo.
