The purpose of the study was to analyze students' perceptions of YouTube as authentic teaching material in online classes. The research method uses qualitative. Participants were taken from the Grammar and Speaking classes as many as 50 students from the English Language Program at Universitas Indraprasta Jakarta. Data were collected using interviews and questionnaires. Data analysis used interactive model analysis form Miles and Huberman that were the stages of data reduction, data display, and concluding. The results show that YouTube can become authentic material if it has content, plot, duration, and originality that suit the needs and learning objectives. Videos on YouTube also have quality and clear sound. However, YouTube is not only assumed to be the main authentic teaching material, but it will be better if it is equipped with journals, websites and books. The results of this study have implications that teachers must know the needs of students regarding teaching materials and videos that are made should be by the level of learning needs
Hükümlü Ailelerinin Baş Etme Stratejileri
Authors: Doğan Betül Kübra , Karataş Kasım
Published: July 2022

Hükümlülük olgusu, yalnızca işlediği suçun ardından mahkemece hakkında hapis cezasına karar verilen bireyi değil bireyin ailesini de yakından etkilemektedir. Bireyin yokluğu ya da “hükümlü” olması sebebi ile çeşitli sorunlar yaşayan aileler, yaşadıkları sorunlar ile baş edebilme amacı ile çeşitli stratejiler geliştirmektedir. Bu çalışmada, hükümlü ailelerinin hükümlülük sonrasında yaşadıkları sorunlar ile baş etme stratejilerinin ortaya konulması amaçlanmıştır. Niteliksel araştırma yönteminin kullanıldığı araştırmada fenomenolojik yaklaşımdan yararlanılmış ve araştırmanın katılımcılarına amaçlı örneklem yoluyla ulaşılmıştır. Eşi hükümlü olan ve halihazırda ceza infaz kurumunda bulunan 17 hükümlü eşi (14 kadın, 3 erkek) ile derinlemesine görüşmeler gerçekleştirilmiş ve ailelerin baş etme biçimleri (i) psikososyal, (ii) ekonomik ve (iii) infaz sürecinden kaynaklanan sorunlarla baş etme stratejileri olmak üzere üç alt başlık altında ele alınmıştır.
Psikososyal sorunlar ile baş etme noktasında katılımcıların eşlerine duydukları sevginin ve çocuk sahibi olmaları nedeni ile güçlü durmaları gerektiğine yönelik inançlarının güçlü bir motivasyon kaynağı olduğu, ailelerin şükretme ya da dini inanca sığınma yolu ile bu süreci atlatmaya çalıştığı, aile ve sosyal desteğin etkisinin büyük olduğu, yaşanan damgalanma ve sosyal dışlanma deneyimleri karşısında hükümlülük durumunun genelde çevreden gizlendiği ya da durumun gizlenmesi amacı ile ailelerin bir kısmının taşındığı/göç ettiği görülmektedir. Ailelerin yaşadığı ekonomik sorunlarla baş etme yöntemlerinde ekonomik sorunları daha derin deneyimleyen kadın katılımcıların; eşlerinin hükümlülüğünün ardından ellerindeki ile yetinmeye çalışmaları, kendilerinin ya da çocuklarının çalışmaya başlaması, eşlerinin ya da kendi kök ailelerinin desteği ile veya sosyal yardımlar ile hayatlarını idame ettirmeleri dikkat çekmektedir. Katılımcıların infaz sürecinden kaynaklı sorunlar ile baş etme stratejilerinin ise ceza infaz kurumlarına ulaşım için bulunan alternatifler ve çocuklara infaz sürecindeki aramalar ve uygulamalar hakkında yapılan açıklamalar çerçevesinde şekillendiği görülmektedir. Ailelerin yaşanan sorunlarla baş edebilme noktasında genelde kendi kapasite ve koşulları doğrultusunda, duygusal odaklı baş etme stratejilerini benimsemeleri ve profesyonel desteklere-hizmetlere erişim noktasında sorunlar yaşamaları ise araştırmada bir diğer önemli bulgudur.

Published: July 2022

Predators adapt their foraging behavior to exploit a variety of prey in a range of environments. Short-finned pilot whales are wide-ranging predators in tropical and sub-tropical oceans, but most previous studies of their foraging ecology have been conducted near oceanic islands. We deployed sound- and movement-recording tags on 43 short-finned pilot whales off Cape Hatteras, North Carolina, USA, to measure their foraging behavior in a continental shelf-break ecosystem and investigate how variation in the environment shapes their behavior. Overall, the foraging behavior of pilot whales off Cape Hatteras was similar to that of their counterparts from island-associated habitats. Off Cape Hatteras, pilot whales made foraging dives as deep as 1077 m (mean: 445 m), lasting up to 23 min (mean: 12.8 min), with sprints (pursuit at speeds over 3 m s-1and up to 6.9 m s-1) in more than half of foraging dives. However, tagged whales off Cape Hatteras produced higher buzz rates (11.3 buzzes dive-1), foraged more extensively in daytime hours, and engaged in more frequent benthic foraging than island-associated ecotypes. By parsing the echoic scene generated by the animal’s own echolocation clicks, we show that pilot whales off Cape Hatteras frequently exploit bathymetric features for foraging, with benthic dives resulting in higher prey capture attempts than pelagic dives. The ability of these predators to strategically adapt foraging strategies to local habitat features likely contributes to their ecological success and may allow them to adjust to shifts in prey distributions in a rapidly changing Anthropocene ocean.
Narrating the Infant: A New Look at the Films of James and Joyce Robertson
Authors: Joice Katie
Published: July 2022

James Robertson’s early films of hospitalized children, particularly A Two Year Old Goes to Hospital (1952), are frequently cited in histories of child psychoanalysis and child psychiatry. Much less is known about the later phase of the research he undertook with his wife, Joyce Robertson, into substitute mothering and the nursery setting. This project was documented in the film series Young Children in Brief Separation ( YCBS) (1967), in which the Robertsons acted as foster parents to four children temporarily separated from their mothers. They made a contrasting film, John, about a young boy’s nine-day stay in a residential nursery, where the effects of discontinuous care on the child’s mind are starkly revealed. Drawing on the concept of the narrative self, this article examines the YCBS series for the first time in the historical literature, exploring the films’ clinical and socio-political meanings. In this new account of the Robertson films, cinematic storytelling becomes a means of exposing, and militating against, psychological fragmentation in the mind of the child, carer and film-viewer.
From Anti-Freudianism to a Bastion of Psychoanalysis: A History of Psychoanalysis at the University Psychiatric Clinic of Strasbourg in the Twentieth Century
Authors: Serina Florent
Published: July 2022

By contrast with a dominant part of the historiography of psychoanalysis in France, which tends to be dedicated to the history of the centres and the biography of the great theorists, this article focuses on the less well known history of psychoanalysis in a peripheral region, namely Alsace, and its capital, Strasbourg. It zooms in on the main central university hospital service in the mental health care system of northeastern France, the University Psychiatric Clinic of Strasbourg. On the basis of abundant and varied sources, it relates the passions, attractions and aversions that Freudian methods aroused among the major protagonists of Strasbourg psychiatry, especially Théophile Kammerer (1916–2005), the director of the Clinic from 1953 to 1982, and the various actors (physician or non-physician) that have circled the establishment throughout the twentieth century.
Party Realignment, Education, and the Turnout Advantage
Authors: Goidel Spencer , M.Q. Moreira Thiago , Armstrong Brenna
Published: July 2022

Education is a strong---if not the strongest---predictor of political participation. As non-college voters align with the Republican Party, it is necessary to revisit the partisan effect of turnout. We predict that, since 2016, the Democratic Party benefits from lower turnout. Using validated voter turnout from the Cooperative Election Study (CES), we simulate election results across turnout rates for the 2008, 2012, 2016, and 2020 presidential elections. Our findings show that increases in turnout benefit the Democratic Party in 2008 and 2012. However, this pattern has drastically changed. In 2016 and 2020, the Democratic Party is advantaged by lower turnout. During this period, the profile of marginal voters has also changed: less educated voters most on the fence about participating in presidential elections are increasingly Republican. These results indicate that continued party realignment along the lines of education could lead to a persistent reversal in the expected partisan effect of turnout.
New Material of Carbonaceous Compressions from the ∼1.5 Ga Singhora Group, Chhattisgarh Supergroup, India, and their Interpretation as Benthic Algae
Authors: Singh Veeru Kant , Sharma Mukund
Published: July 2022

The origin, antiquity, and affinity of benthic seaweeds (multicellular algae) in the geological past are shrouded in mystery due to their preservation bias. In this study, we present a new material of well-preserved carbonaceous compression fossils in shale horizons of the Mesoproterozoic (ca. ∼1,500–1,300 Ma) Singhora Group of the Chhattisgarh Supergroup. Eleven distinct taxa, including one new taxon,Palaeoscytosiphon shuklaii, n. gen. et. sp., and one new species,Jiuqunaoella sergeevii, n. sp., are established. Four unidentified morphologies are also reported. Morphologically, the carbonaceous fossils are fan-shaped, palmate, elongated, leaf-like algal thalli with/without holdfast at the base, isolated or dichotomously branched long filaments, along with multicellular reproductive structures. The results of laser Raman spectroscopy and energy dispersive X-ray spectroscopy (EDX) are also presented in support of their biogenicity. Collectively, the preservation mode of the Singhora carbonaceous fossils suggests multicellular algal affinity and adds to a Burgess Shale-type (BST) taphonomic window in the Pre-Ediacaran biosphere.
Tax Policies of Low Carbon in China: Effectiveness Evaluation, System Design and Prospects
Authors: Feng Ping , Lu Hongyuan , Li Wei , Wang Xinyu
Published: July 2022

Fiscal and taxation policy tools play an important role in promoting green and low-carbon development. Based on classical tax theory, including the Potter hypothesis and the environmental Kuznets curve, this paper explores the impact of environmental tax regulation on economic growth and carbon emission reduction. We find that resource tax reform could promote green total factor productivity; however, the ad valorem reform of resource tax does not significantly raise the level of low carbon development. This effect varies among different regions as well as different tax cuts and fee reductions. Fiscal revenue decentralization has a reverse adjustment effect on the impact of resource taxes on green total factor productivity. We conclude that it is necessary to deepen the reform of the fiscal and taxation system to achieve the carbon neutrality and emission peak goal.
SecAODV: A Secure Healthcare Routing Scheme Based on Hybrid Cryptography in Wireless Body Sensor Networks

Published: July 2022

In recent decades, the use of sensors has dramatically grown to monitor human body activities and maintain the health status. In this application, routing and secure data transmission are very important to prevent the unauthorized access by attackers to health data. In this article, we propose a secure routing scheme called SecAODV for heterogeneous wireless body sensor networks. SecAODV has three phases: bootstrapping, routing between cluster head nodes, and communication security. In the bootstrapping phase, the base station loads system parameters and encryption functions in the memory of sensor nodes. In the routing phase, each cluster head node calculates its degree based on several parameters, including, distance, residual energy, link quality, and the number of hops, to decide for rebroadcasting the route request (RREQ) message. In the communication security phase, a symmetric cryptography method is used to protect intra-cluster communications. Also, an asymmetric cryptography method is used to secure communication links between cluster head nodes. The proposed secure routing scheme is simulated in the network simulator version 2 (NS2) simulator. The simulation results are compared with the secure multi tier energy-efficient routing scheme (SMEER) and the centralized low-energy adaptive clustering hierarchy (LEACH-C). The results show that SecAODV improves end-to-end delay, throughput, energy consumption, packet delivery rate (PDR), and packet loss rate (PLR).
The role of enriched environment in neural development and repair

Published: July 2022

In addition to genetic information, environmental factors play an important role in the structure and function of nervous system and the occurrence and development of some nervous system diseases. Enriched environment (EE) can not only promote normal neural development through enhancing neuroplasticity but also play a nerve repair role in restoring functional activities during CNS injury by morphological and cellular and molecular adaptations in the brain. Different stages of development after birth respond to the environment to varying degrees. Therefore, we systematically review the pro-developmental and anti-stress value of EE during pregnancy, pre-weaning, and “adolescence” and analyze the difference in the effects of EE and its sub-components, especially with physical exercise. In our exploration of potential mechanisms that promote neurodevelopment, we have found that not all sub-components exert maximum value throughout the developmental phase, such as animals that do not respond to physical activity before weaning, and that EE is not superior to its sub-components in all respects. EE affects the developing and adult brain, resulting in some neuroplastic changes in the microscopic and macroscopic anatomy, finally contributing to enhanced learning and memory capacity. These positive promoting influences are particularly prominent regarding neural repair after neurobiological disorders. Taking cerebral ischemia as an example, we analyzed the molecular mediators of EE promoting repair from various dimensions. We found that EE does not always lead to positive effects on nerve repair, such as infarct size. In view of the classic issues such as standardization and relativity of EE have been thoroughly discussed, we finally focus on analyzing the essentiality of the time window of EE action and clinical translation in order to devote to the future research direction of EE and rapid and reasonable clinical application.
Impact of DC-Coupled Electrophysiological Recordings for Translational Neuroscience: Case Study of Tracking Neural Dynamics in Rodent Models of Seizures
Authors: Jafarian Amirhossein , Wykes Rob C.
Published: July 2022

We propose that to fully understand biological mechanisms underlying pathological brain activity with transitions (e.g., into and out of seizures), wide-bandwidth electrophysiological recordings are important. We demonstrate the importance of ultraslow potential shifts and infraslow oscillations for reliable tracking of synaptic physiology, within a neural mass model, from brain recordings that undergo pathological phase transitions. We use wide-bandwidth data (direct current (DC) to high-frequency activity), recorded using epidural and penetrating graphene micro-transistor arrays in a rodent model of acute seizures. Using this technological approach, we capture the dynamics of infraslow changes that contribute to seizure initiation (active pre-seizure DC shifts) and progression (passive DC shifts). By employing a continuous–discrete unscented Kalman filter, we track biological mechanisms from full-bandwidth data with and without active pre-seizure DC shifts during paroxysmal transitions. We then apply the same methodological approach for tracking the same parameters after application of high-pass-filtering >0.3Hz to both data sets. This approach reveals that ultraslow potential shifts play a fundamental role in the transition to seizure, and the use of high-pass-filtered data results in the loss of key information in regard to seizure onset and termination dynamics.
Genomic Landscape of RTK/RAS Pathway and Tumor Immune Infiltration as Prognostic Indicator of Lung Adenocarcinoma
Authors: Yin Xiang-Qian , Yin Xue-Hui , Yu Ya-Qin , Xu Lang , Zhang Mao
Published: July 2022

The RTK/RAS pathway is an oncogenic signaling pathway for which many targeted drugs have been developed; however, survival remains poor. A combination of targeted therapy and immunotherapy has emerged as an option for improving cancer treatment responses. In this study, on the basis of the expression, survival, single nucleotide variation (SNV), copy number variation (CNV), and methylation data of lung adenocarcinoma (LUAD) from The Cancer Genome Atlas database, we comprehensively analyzed the genomic changes in the RTK/RAS pathway and their associations with tumor-infiltrating lymphocytes (TIL) and prognosis in LUAD to provide the genomics landscape of RTK/RAS with TIL and prognosis. We found that two rarely mutated genes, mitogen-activated protein kinase kinase 1 and insulin-like growth factor 1 receptor, were significantly associated with the worse survival of patients with LUAD. Patients with LUAD and co-mutation of KRAS proto-oncogene (KRAS) and neurofibromin 1 genes had worse survival, and the underlying mechanism could be insufficient for protein synthesis and intracellular signal deactivation. Methylation of the Rac family small GTPase 1 (RAC1) was associated with better survival. The SNVs of the top mutated genes, including epidermal growth factor receptor (12.7%), neurotrophic receptor tyrosine kinase 3 (7.8%), erb-b2 receptor tyrosine kinase 4 (8.5%), and KRAS (29.6%), were associated with T cell exhaustion in LUAD. To construct nomograms, we further screened the genes whose genomic changes were closely associated with survival and immune infiltration. The nomograms performed well in predicting disease-specific survival (DSS) with a concordance index of 0.7 (0.589, 0.811) and overall survival with a concordance index of 0.689 (0.603, 0.775) in test set; they also showed good correspondence between actual and ideal nomogram predictions. Tumor stage, RAC1 methylation, and type 1 regulatory T cells greatly contributed to DSS and OS nomograms. In summary, we provided a comprehensive genomic profile of the RTK/RAS pathway in LUAD and its association with immune cell infiltration and prognosis of LUAD. This profile would serve as a basis for developing better therapeutic strategies, improving patient prognosis, and understanding the mechanisms of immune disturbance from the perspective of oncogenic pathways of LUAD.

Published: July 2022

Background

The COVID-19 pandemic hit Austria in March 2020. This led to a considerable reduction in outpatient psychiatric therapies. People with mental disorders as well as with newly emerging mental health issues found themselves with very limited treatment options. Within only a few days our hospital set up an online mental health self-help program which went online in its first version on the first day of the lockdown in Austria. The process of this development and implementation process alongside with the user’s and usage data for the program are presented here.

Methods

A small core team initiated the development of the program on a low-budget basis and using mostly freely available digital resources. The program had to be free of costs for its users and easy to navigate. Each self-help module contains a text description of the topic, a self-rating questionnaire and several psychoeducational 2–5 min videos. These videos explain, e.g., interactions of mental stress and the immune system or the vicious circle of anxiety. Additional videos provide easy to learn techniques like breathing and relaxation exercises.

Results

We illustrate the implementation of this program following the replicating effective program (REP) model. We provide a detailed description of the implementation process starting from a simple website to a smartphone-based application with registered user area and instantaneous reporting of self-rating questionnaire results to users. The described process could be used as a model for the setup of similar programs in a very short time. As an indicator of acceptance, we report 46,100 unique video views and 3,937 completed questionnaires in the first year of use. The most accessed videos were those on anxiety, relaxation and resilience. Analysis of the sociodemographic user data indicate that they were mostly young (< 45 years; 59.7%), females (77.5%) and previously mentally healthy individuals (74.5%). An example of the collected psychometric questionnaire data over time is given.

Conclusion

We show that it is possible to set up an online mental health self-help programad hocand without extensive prior planning, which enabled us to dynamically respond to a new situation. We are now planning on keeping the program active for a longer period of time to supplement and expand traditional treatment settings also outside the COVID-19 pandemic.

Given their central role and position, coaches are instrumental in creating safe sport environments, especially in preventing sexual violence, but little is known about bystander behaviors, hampering the development of effective bystander programs in the context of sport. To identify determining characteristics of bystander behavior, 1,442 Belgian youth sport coaches completed an online questionnaire on bystander-related attitudes, norms, autonomy beliefs, and self-efficacy using two hypothetical scenarios of sexual violence in the sports club. Data were analyzed using confidence interval-based estimation of relevance (CIBER). A total of 127 coaches had witnessed sexual violence over the past year, most but not all intervened. Experiential attitude expectation, instrumental attitude evaluation, perceived referent behavior and approval, and subskill presence were positively associated with coaches’ intention to intervene. Of the determinants of positive coach-bystander behavior, attitude and perceived norms proved key constituents for programs addressing sexual violence in youth sport. We conclude that interventions aiming at increasing positive affective consequences, reinforcing the sense of group membership, and strengthening the social norm of intervening in case of signs of sexual violence may be most influential to stimulate positive coach-bystander behavior.

Authors: Cai Qun , Duan Jinnan , Ding Liang
Published: July 2022

Background

Immune-related genes (IRGs) are closely connected to the occurrence and development of tumors. Their influence on the prognosis of patients with HCC, however, remains unclear.

Methods

From the TCGA database, we integrated 365 liver cancer tissues and 50 normal tissues to identify differential immune genes related to prognosis. Multivariate COX analysis was used to establish a new prognostic index on account of IRGs, whereby risk score = (Expression level of HSPA4*0.022) + (Expression level of PSMD14*0.042) + (Expression level of RBP2*0.019) + (Expression level of MAPT*0.197) + (Expression level of TRAF3*0.146) + (Expression level of NDRG1*(0.006) + (Expression level of NRAS*0.027) + (Expression level of IL17D*0.075).

Results

The risk score was clearly correlated with an unfavorable survival rate and with clinical characteristics. By integrating the immune-related risk score model with clinical features, a nomogram was constructed to predict the survival rate of HCC patients (1-, 3- and 5-year AUC of 0.721, 0.747 and 0.781, respectively).

Conclusion

We have established a valuable prognostic risk score for HCC patients that may be a better predictor of survival than the present method. With the risk score's strong predictive value for immune cells and functions, it may provide clinical guidance for the diagnosis and prognosis of different immunophenotypes, and provide multiple therapeutic targets for the treatment of HCC patients based on subtype-specific immune molecules.
Study on Noise Model of an Automotive Axial Fan Based on Aerodynamic Load Force
Authors: Zhong Yinhui , Li Yinong , Li Jun
Published: July 2022

Due to the fact that the noise caused by axial fan blades of vehicles is large, which seriously affects ride comfort, and there is no effective mathematical model to quantitatively study the contribution of the various parameters of the blades to the noise, a new method for calculating the load force of the blades is proposed. This method obtains the constant load force of the blade according to the blade element momentum theory and the characteristics of the blade structure of the axial fan for a vehicle. At the same time, this method obtains the non-constant load force of the blade by combining the non-constant thin-wing theory and experimental data and then vectors the constant load force and the non-constant load force to obtain the total load force of the blade to build a mathematical model of the relationship between the noise of the fan and the parameters of the blade. According to the model, the total sound pressure level of a fan is calculated numerically and further compared with the FLUENT software simulation and experimental results. The results show that the error of the total sound pressure level calculated by the numerical value is within 3 dB(A). This method provides an important basis for the study of a high-accuracy noise mathematical model and the optimization of blade parameters of low Mach-number fans.

Published: July 2022

Due to the extremely small size and arbitrary orientation of the cracks, a highly sensitive sensor based on the balanced-field electromagnetic technique was designed for in-line inspection of oil and gas pipeline cracks. A balanced-field electromagnetic technique sensor mutual inductance model was established and used to theoretically analyze the parameters affecting sensitivity. Finite element simulation was used to analyze the specific effects of the magnetically conductive medium, the number of coil turns, and the sensor lift-off height on the sensor output, respectively, and the sensor parameters of high sensitivity were determined. The detection effect of the sensor on the pipeline crack was tested by the single-sensor experiment and the pulling test. The results show that the designed balanced-field electromagnetic technique sensor is effective in detecting both circumferential and axial cracks of 0.5 to 6 mm in depth. As the crack depth increases, the sensitivity decreases and the detection voltage amplitude increases linearly. The sensitivity of the sensor is highest when detecting circumferential and axial cracks of 1 mm in depth at 1.76 and 0.87 mV/mm, respectively. In addition, the amplitude of the circumferential crack signal at the same depth is approximately twice that of the axial crack signal.
Heating Sizing Power Reduction in Buildings Connected to District Heating with Dynamically Controlled DHW Setback and Flow Limiters
Authors: Hajian Hatef , Simson Raimo , Kurnitski Jarek
Published: July 2022

Space Heating (SH) substations in District Heating-based (DH) systems are typically dimensioned at the design outdoor temperature without accounting for internal and solar heat gains. In residential buildings, the total required DH power typically also includes the need for Domestic Hot Water (DHW). This practice results in oversized substations and high DH design flow rates, which, due to heat gains and building thermal mass utilization in building operation, rarely, if ever, occur. Modern buildings maintain the desired indoor temperature with lower heating power by controlling the SH supply temperature with an outdoor-air-dependent heating curve and heating water flow with room unit thermostats. Applying a dynamic heating control algorithm can be considered one option to reduce the required DH power and optimize the DH network. Another possibility to decrease the needed power is controlling the DH flow by prioritizing DHW production and limiting the DH flow for SH. This study proposed a novel sizing method for the DH substation that quantifies the effects of dynamic control and flow limiters. Building models with detailed hydronic plants, accounting for internal heat gains, and using conventional and dynamic heating controls were developed in the IDA Indoor Climate and Energy simulation tool. The results show a potential DH side power reduction of up to 25%.

Published: July 2022

The primary wind turbines’ in-service performance evaluation method is mining and analyzing the SCADA data. However, there are complex mathematical and physical relationships between multiple operating parameters, and so far, there is a lack of systematic understanding. To solve this issue, the distribution of wind turbines’ operating parameters was first analyzed according to the characteristics of the energy flow of wind turbines. Then, the correlation calculation was performed using the Spearman correlation coefficient method based on the minute-level data and second-level data. According to the numerical characteristics of the nacelle vibration acceleration, the data preprocessing technology sliding window maximum (SWM) was proposed during the calculation. In addition, taking temperature correlation as an example, two-dimensional scatter (including single-valued scatter) and three-dimensional scatter features were combined with numerical analysis and physical mechanism analysis to understand the correlation characteristics better. On this basis, a quantitative description model of the temperature characteristics of the gearbox oil pool was constructed. Through this research work, the complex mathematical and physical relationships among the multi-parameters of the wind turbines were comprehensively obtained, which provides data and theoretical support for the design, operation, and maintenance.

Biomass from agriculture is a promising alternative fuel due to its carbon-neutral feature. However, raw biomass does not have properties required for its direct utilization for energy generation. Torrefaction is considered as a pretreatment method to improve the properties of biomass for energy applications. This study was aimed at investigating the effects of torrefaction temperature and residence time on some physical and chemical properties of torrefied corncobs. Therefore, a fixed-bed torrefaction reactor was developed and used in the torrefaction of corncobs. The torrefaction process parameters investigated were the torrefaction temperature (200, 240, and 280 °C) and the residence time (30, 60, and 90 min). The effects of these parameters on the mass loss, grindability, chemical composition, and calorific value of biomass were investigated. It was shown that the mass loss increased with increasing torrefaction temperature and residence time. The grinding throughput of the biomass was improved by increasing both the torrefaction temperature and the residence time. Torrefaction at higher temperatures and longer residence times had greater effects on the reduction in particle size of the milled corncobs. The calorific value was highest at a torrefaction temperature of 280 °C and a residence time of 90 min. The energy yield for all treatments ranged between 92.8 and 99.2%. The results obtained in this study could be useful in the operation and design of torrefaction reactors. They also provided insight into parameters to be investigated for optimization of the torrefaction reactor.
