Uma das maiores contribuições na mitigação das mudanças climáticas é o sequestro de carbono provido pelas florestas. Devido a redução das áreas florestais, torna-se necessário a restituição ecológica por meio da recuperação florestal. O objetivo do presente trabalho foi avaliar o crescimento em altura e diâmetro e o acúmulo de carbono na biomassa de plantas de jatobá (Hymenaea courbaril L.) introduzidas em área de recuperação florestal. A área experimental contém 4 ha e está localizada no município de Canaã dos Carajás, PA. As espécies nativas foram inseridas em 2018, dentre elas, 315 mudas de jatobá. As variáveis mensuradas foram: altura da planta (h) e diâmetro de colo (DC). O cálculo de carbono foi realizado através do valor médio da densidade básica da madeira e pelo método indireto de quantificação. Foram calculados os incrementos em altura e em diâmetro do colo, correlação linear, volume de carbono na biomassa das plantas e a taxa de mortalidade. O jatobá apresentou incrementos em altura (h) e diâmetro (DC) de 2,81 m e 4,87 cm respectivamente. Aos 36 meses, o carbono acumulado na biomassa das plantas de jatobá foi de 0,0019 Mg.C-1. A taxa de mortalidade associada à implantação do jatobá para esse trabalho foi de 49,2%.

Listening to Kora in New York City: Constructing Africa and Blackness in the United States
Authors: SullyCole Althea 
Published: May 2022

Abstract
Drawing upon ethnographic fieldwork with New York City-based musicians, this article observes how the kora, a twenty-one stringed harp from the Mandé region of West Africa, has become integrated into a Black cultural expression in the United States. It highlights the disjunctures between migrant West African kora players and Black musicians and audiences in the United States that result from particular modes of listening. How these conflicts are manifest in the performance context, the author argues, reveals both who and what means, historically, have been authorized to organize a social imaginary around the idea of “Africa” and its traditions.

Published: May 2022

Recent investigations by different workers have pointed out the existence of a forty-day mode in the rainfall, cloudiness and circulation over the monsoon area. In the present investigation an attempt has been made to examine the potentiality of this, quasi-stationary periodic mode for the purpose of medium range forecasting, of rainfall over the Indian subcontinent. The analyses of the rainfall and mean weekly circulation features over India have been carried out for this purpose for a period of 5 years (1979.83). It is observed that this periodicity is variable from year to year and also from one area to the other in the same year. As compared to the existing dynamical parameters which can be used as potential parameters for the medium range rainfall forecasting, the forty-day mode in rainfall or circulation does not seem to have a better skill.

Published: May 2022

Disease states such as hepatitis C and HIV are both associated with methamphetamine (METH) use and are known to produce liver dysfunction. Indeed, bile duct ligation (BDL)-induced liver dysfunction enhances METH effects in rats. While female rats are more sensitive to METH, male rats are more prone to BDL-induced liver damage. The objective of this study was to determine if BDL disproportionately affects METH pharmacokinetics in male compared to female rats. On day 0, sham or BDL surgery was performed on male and female rats. On day 7, serum biomarker samples were collected prior to pharmacokinetics studies with 3 mg/kg subcutaneous METH. METH-induced weight loss was measured on day 8. On day 9, samples were collected for liver histology and brain METH concentration measurement. While BDL surgery produced significantly elevated alanine aminotransferase and bile duct proliferation in male versus female rats, there were no significant interactions between sex and liver function in the pharmacokinetic parameters. Both liver dysfunction and female sex, however, were associated with significantly slower serum METH clearance and higher brain METH concentrations (p<.05). While there were no sex-dependent differences, there was a significant reduction in post-METH weight in BDL compared to sham animals (p<.05). BDL-induced hepatic dysfunction produces substantial elevations in serum and brain METH exposure in both male and female rats. This inexpensive model could potentially be used to find and correct liver dysfunction-related issues with future METH use disorder medications prior to expensive clinical trials.

A Face Mask and Body Temperature Detection System using Raspberry Pi
Authors: Boone Jacob , Liao Weidong 
Published: May 2022

In this presentation, we describe our face mask and body temperature detection system implemented using Raspberry Pi. This project aimed to develop a portable face mask detection and temperature reading device that detected if a person was wearing a face mask and their temperature was within a specific range. An MLX90614 infrared (IR) sensor was interfaced with a raspberry pi and used to detect an object's temperature within its field of view. The operating distance of this specific IR sensor is 2cm-5cm. The detection software program utilizes the Python library smbus2 and the locally stored folder mlx90614 to read the object temperature from the IR sensor, convert the Celsius temperature to Fahrenheit. If the detected temperature is within the preset range and the MobileNetV2 model sees that the person is wearing a mask, then a green box is displayed around the person's head. If the detected temperature is out of the range and the model predicts the person is not wearing a mask, then there is a red box outlining the person's face. This project is sponsored by WV SOARS grants from Shepherd University.

Aesthetic Origin of the Metal and Stone Sound in the Chinese Seven-String Zither Music
Authors: Li Ziran 
Published: May 2022

The metallic and stony instruments in the ancient eight-tone system symbolized the hierarchical order and noble rights in the pre-Qin ritual music system. The sound of metal and stone represents the beauty of the highest ritual music system, which is "always in order". During the Eastern Zhou Dynasty, the Chinese seven-string zither became a vessel for the scholars to blend the ritual order with their individual emotions, thanks to the preference of the scholars. In the Han Dynasty, with the rise of the scholar class, the Chinese seven-string zither was pushed to the altar of “ritual and music”, following the path of the sound of metal and stone. The sound of metal and stone has influenced the making and playing of the Chinese seven-string zither since the Tang Dynasty - the sound of metal and stone has become the aesthetic standard of the Chinese seven-string zither music.

Authors: Chen Ran 
Published: May 2022

Based on the daily stock data of 49 industry classification data in Kenneth R. French database, this paper adopts the Fama-French five-factor model and adopts multiple linear regression method to empirically study the changes of stock return impact factors of 49 us industries before and after COVID-19. The results show that the marginal effects of market risk factors and investment style factors on stock returns weaken, while the marginal effects of market value factors and value factors increase. The influence of profit factor on stock return is not significant. Post-pandemic, the market favors small-cap stocks, value stocks, and conservative portfolios. Specific to the industry level, the small market value and value stock portfolio of the hotel and catering industry bring greater excess returns; The rare metal industry of high market value, growth stock portfolio excess return is greater; Textile industry value stocks, investment style aggressive portfolio to get better returns. Based on this, when the "black Swan" event comes, we should pay attention to grasp the switch of investment style in order to achieve better returns. At the same time, specific to each industry investment strategy should be different.

In order to promote carbon reduction in the manufacturing industry, measures have been taken to promote the low-carbon transformation of the manufacturing industry, and then promote the harmonious development of the economy and ecology. Data were found from bp World Energy Statistical Yearbook and CEADs database, and the method of gray prediction was used to predict the carbon emissions in the coming years. At the same time, measures were found by finding literature, and the implementation order of measures was finally determined according to their AHP model. It was found that the carbon emissions in 2022 are estimated to be 10179.18 million tons, and the carbon emissions in 2023 are estimated at 10213.53tn, which shows that the carbon emissions in the next few years are at a high level, so as a high carbon emission manufacturing industry must take measures. According to data search and expert opinions, we can determine the weight and calculate the final measures that need to be taken to focus on process optimization, raw material substitution, low-carbon travel of enterprise personnel, etc. Through the estimation of future carbon emissions and the decision model of measures, we can find that the manufacturing industry, as a large part of carbon emissions, has high economic, environmental and social benefits after taking effective actions.

Authors: Gao Jiesheng , Cai Zhucen 
Published: May 2022

Accounting is a language to record economic life, and with the rapid development of productivity and economic and social progress in China, accounting standards are constantly updated to meet the needs of accounting practice and promote the effective operation of socialist market economy. China promulgated the Accounting Standards for Business Enterprises in 1992 as the highest authority of accounting regulations, which has been developed and improved for nearly 30 years, but it is undeniable that the current Chinese accounting standards (CAS) have borrowed from Western accounting standards especially the International accounting standards (IAS) to a considerable extent. In this paper, from the development history of CAS, through the analysis of the causes and effects of the overall differences and specific differences between the two systems on the financial statements of enterprises, combined with the SWOT-PEST model, we make a reasonable outlook on the development of CAS.
