This study was designed to evaluate the effects of Moringa oleifera (L) aqueous seed extract on aphrodisiac, gonadal and epididymal sperm reserves of Wistar rats. Twenty-five male and fifteen female Wistar rats aged two months weighing 150 – 200 g were purchased and housed in cages at the Faculty of Pharmaceutical Science, Ahmadu Bello University Zaria. The Wistar rats were provided with a 12 hours light and dark cycle, fed with pellets of broiler starter and drinking water were provided ad libitum. The rats were acclimatized for 14 days and they were randomly divided into 5 groups A, B, C, D and E. Group B, C and D as treatment groups, whereas, group A and E were negative and positive controls, respectively, with 5 rats in each group and each was kept singly in separate cage. Groups A and E received 1 ml of distilled water and 5 mg of sildenafil citrate orally respectively. Groups B, C and D received suspension of Moringa oleifera aqueous seed extract orally at the dose rate 100, 200 and 300 mg/kg respectively, between 9:00 - 10:00 am daily for 21 days. Female rats were paired with males at a ratio of 1:1, and mating behaviour recorded. Group C and E male rats showed a significant (p < 0.05) increase in mounting frequency (MF), respectively. Intromission frequency (IF) was significantly (p < 0.05) increased in group C and E, respectively. Gonadal and epididymal sperm reserves were significantlydifferent (p < 0.05)between the M. oleifera treated and control groups.

Published: September 2021

Post-mortem examination was carried out on a 2-week old male Friesian crossbred calf to determine the cause of death. The body condition of the calf was fair with pale mucous membranes. There was petechial to ecchymotic epicardial haemorrhages with mild hydroperitoneum and hepatomegaly. The enlarged rumen contained a large amount of white offensive rancid-smelling curdled milk mixed with watery content while the abomasum contained some sand sediment. A diagnosis of acute ruminal drinking was made based on the calf's age, reportedly feeding entirely on milk ration, and the presence of a large amount of curdled milk in the rumen. Early diagnosis and the treatment of underlying pathological conditions, correction of predisposing management practices, and rumenostomy are some of the ante-mortem ways to combat and improve the prognosis of the condition in affected calves.

Unhygienic slaughtering practices are associated with meat contamination by pathogens including Listeria monocytogenes. This study investigated the occurrence, bacterial load, antimicrobial susceptibility and biofilm formation of L. monocytogenes in pork, slaughter facilities and water from Oko-Oba abattoir, Lagos State, Nigeria. A total of 216 samples; 146, 30, 20 and 20 from pork, water, table swabs and knife swabs respectively were collected for bacteriological analysis. Listeria selective media was used to isolate and characterise L. monocytogenes, antimicrobial susceptibility of the isolated bacteria was also determined. Biofilm production by the isolates for periods of 12, 24 and 36 hours were evaluated. Glucose, ethanol and crystal violet binding assay were used as nutrient, stressor and indicator respectively. The occurrence of L. monocytogenes in pork, water samples, table and knife swabs were 64.5%, 75%, 90% and 95% respectively, while overall prevalence was 73.3%. The mean load per gram were 3.78 ± 2.85, 4.27 ± 2.54, 5.60 ± 1.95 and 5.52 ± 1.41 (p ˂ 0.05) for pork, water table and knife swab samples, respectively. Fifty five percent of the isolates exhibited multidrug resistance (MDR) patterns to erythromycin (55%), tetracycline (55%), augmentin (85%), amoxicillin (90%), cotrimoxazole (95%), and cloxacillin (100%). The isolates produced biofilms at different concentrations of glucose and ethanol with the highest concentrations of biofilm produced at 36 hours. There were significant differences in mean biofilm values produced by the isolates. The occurrence of L. monocytogenes and the bacterial load in different samples are of economic and public health importance. Hygienic meat production from the abattoir could prevent contamination of pork by L. monocytogenes.

Published: September 2021

Commercial quail farming is economically viable and feasible because quails are resistant tovarious diseases. But despite this reported resistance, little is known about its resistance tohaemoparasites. This study evaluates the haematological changes and haemoparasiticinfection of commercially raised quails. Fifty-seven adult quails raised on deep litter wererandomly selected for blood sampling in this study. Two milliliters of blood was collectedaseptically for complete blood count while blood smears were used for the determination ofhaemoparasite morphological characteristics. Haemoproteus spp. Plasmodium gallinaceum, and Leucocytozoon spp. were identified in this study. 38 (67%) of the quails were positive forsingle or mixed infection, 29 (51%) were positive for single infection and 9(16%) for mixedinfection. There was a (P<0.05) decrease in PCV, Hb, and RBC counts, and an increase inTWBC and eosinophil count in birds with haemoparasite as compared to the uninfected birds.There was (P<0.05) increase in total white blood cell and heterophil count in the plasmodiumpositive birds. Also, total white blood cell, heterophil, lymphocyte and eosinophil count were(P<0.05) increased in the Leucocytozoon positive birds. This increase was also observed inbirds with mixed infection. The high incidence of haemoparasitic infection in apparentlyhealthy quail, with significant haematological indices deviated from normal, is consistentwith reports of the resistance of quail to various disease diseases which thus includeshaemoparasitic infection.

Systems Thinking for Sustainability
Authors: Jenkins Bryan
Published: September 2021

A sustainability framework based on nested adaptive socio-ecological systems is used to analyse historical examples of soil erosion and its implications for food production and security for a growing population. While there are examples of innovation in agriculture to address food availability, there are also cases of inadequate social responses leading to famine. The analysis highlights the value of considering these issues in a framework of linked biophysical and socio-economic systems. The socio-economic system generates management interventions to resolve biophysical limitations such as soil depletion on food production. The socio-economic system is also responsible when there are inadequate social responses. Currently, the biophysical system produces enough food to feed the world population. However, food distribution through the socio-economic system results in increasing numbers of undernourished people. Biophysical system modelling indicates that unless major changes are made to the current world system, overshoot because of resource depletion will lead to system collapse within the 21st century. To develop sustainability strategies, we need to analyse the socio-economic response to this biophysical vulnerability. A socio-ecological analysis also indicates that perspectives based on power relations that govern real-world decision making rather than sustainability interventions to address food security, need to be incorporated.
Evidence-Based Course Modification to Support Learner-Centered and Student-Driven Teaching in A Pandemic: Leveraging Digital and Physical Space for Accessible, Equitable, and Motivating Experiential Learning and Scientific Inquiry in A First-Year Biology Course
Authors: Robertson Lisa , Porter Elizabeth , Smith M. Alex , Jacobs Shoshanah
Published: September 2021

The COVID-19 pandemic posed, and continues to pose, many challenges to teaching and learning, most notably the need to pivot from traditional in-person course instruction and experiences to entirely virtual course delivery while maintaining course rigor and quality. Our guiding principle for course modification was the critical need for an equitable, accessible, engaging, and motivating learning experience for students that maintained the learning outcomes and objectives of the course in a fully virtual and digitized format. This paper illustrates the evidence-based approach that the instructional team of a first-year biology experiential learning course took in response to the need for instruction to occur in virtual space and time for the Fall 2020 (September to December 2020) semester.

In-stent stenosis is a feared complication of flow diversion treatment for cerebral aneurysms. We present 2 cases of patients treated with pipeline flow diversion for unruptured cerebral aneurysms. Initial perioperative dual antiplatelet therapy (DAPT) consisted of standard aspirin plus clopidogrel. At 6-month follow-up cerebral angiography, the patients were noted to have developed significant in-stent stenosis (63% and 53%). The patients were treated with cilostazol and clopidogrel for at least 6 months. Subsequent angiography at 1-year post-treatment showed significant improvement of the in-stent stenosis from 63% to 34% and 53% to 21%. The role of cilostazol as treatment of intracranial in-stent stenosis has not been previously described. Cilostazol’s vasodilatory effect and suppression of vascular smooth muscle proliferation provides ideal benefits in this setting. Cilostazol plus clopidogrel may be a safe and effective alternative to standard DAPT for treatment of in-stent stenosis following flow diversion and warrants further consideration and investigation.

‘NATIONAL COLLECTIONS OF CONTEMPORARY
ART’: PROGRAMME OF THE MINISTER OF
CULTURE AND NATIONAL HERITAGE TO FINANCE
PURCHASES OF CONTEMPORARY ART WORKS
IN 2011–2019 PART 1. HISTORY: FINANCING
Authors: Szafrański Wojciech
Published: September 2021

The ‘National Collections of Contemporary Art’
Programme run by the Ministry of Culture and National
Heritage (MKiDN) in 2011–2019 constituted the most
important since 1989 financing scheme for purchasing
works of contemporary art to create and develop museum
collections. Almost PLN 57 million from the MKiDN budget
were allocated by means of a competition to purchasing
works for such institutions as the Museum of Modern
Art in Warsaw (MSN), Museum of Art in Lodz (MSŁ),
Wroclaw Contemporary Museum (MNW), Museum of
Contemporary Art in Cracow (MOCAK), or the Centre of
Polish Sculpture in Orońsko (CRP). The programme in
question and the one called ‘Signs of the Times’ that had
preceded it were to fulfil the following overall goal: to
create and develop contemporary art collections meant for
the already existing museums in Poland, but particularly
for newly-established autonomous museums of the 20th
and 21st century. The analysis of respective editions of the
programmes and financing of museums as part of their
implementation confirms that the genuine purpose of
the Ministry’s ‘National Contemporary Art Collections’
Programme has been fulfilled.
Talking of Many Things: Dashboards for Reference Services Decision Making
Authors: Chua Hui Hua , Minkin Rachel M.
Published: September 2021

Staffing challenges are well-documented in reference services, but the use of
dashboards to support data-driven scheduling for in-person and virtual reference shifts
are not often discussed. This poster examines how Michigan State University Libraries
utilized data-influenced decision-making and dashboard design iterations to streamline
reference staffing and adapt to evolving conditions over the course of three years. This
required continuous communication between dashboard users and creators and constant
iteration of visualizations and designs to ensure dashboards remained relevant and
current. Limitations of a purely quantitative data-driven strategy are also discussed at
the conclusion of the final year.
Collections Data, Tools, and Strategy: Applying R, Tableau, and Excel to Print
Assessment
Authors: Jahnke Lori M. , Palazzolo Chris
Published: September 2021

As is the case at most academic libraries, collection assessment has become an
essential component of collection management and development work. Although much of the
assessment focus has disproportionately fallen on e-resources, print collections remain
fruitful areas for evaluation and review. At Emory, print collections, including a
complex approval plan, continue to be a significant component of our overarching
collection strategy (in volume and expenditure). However, shifting priorities for
library space and the growth of interdisciplinary programs and centers within the
University are placing a higher demand on subject librarians for communication and
coordinated decision-making regarding print acquisitions. As a result, we are currently
preparing for a comprehensive print collection review, of which the approval plan is an
integral component. This assessment will inform a more coherent print strategy, which
effectively and efficiently meets research and teaching requirements as well as
administrative needs. Using data cleaning and visualization tools, such as R, Excel, and
Tableau, we have enriched our local usage data with detailed Gobi approval data (e.g.,
series, publisher, subject, etc.) and profile parameters. Merging these data types and
enriching local use data will allow us to analyze the print collection in a more nuanced
fashion and ask questions that do not require the LC classification framework. This
analysis considers the development of additional tools and approaches that facilitate
subject specialist communication with collection management and overall collaborative
decision-making, especially in cross disciplinary areas.

and Quantitative Data
Authors: Sly Jordan S. , DePope Leigh Ann , Frank Cynthia G. , Ritchie Stephanie M.
Published: September 2021

This paper will address the development process of a qualitative evaluation tool
to aid in the thorough analysis of library resources at the University of Maryland.
Specifically, our project looks at the use and added value of this tool for the
building, reflecting, and analyzing the connections between qualitative and quantitative
data. This will allow for more meaningful justifications of budgetary decisions compared
to cost and use metrics alone. Given the necessity for meticulous review of continuing
resources, our project addresses a request for enhanced transparency from the university
faculty and library oversight bodies and serves as a useful tool for accountability and
justification of impactful decisions for stakeholders internally and externally. We will
discuss the extant literature and the need for this type of tool, the development
process including the output planning and data input format, the initial reception of
the project, and future goals and planning for our initial usage. Additionally, we will
demonstrate the use of the tool, model output, and discuss options for visualizations,
storage, and retrieval of input data.
The Forest, The Trees, The Bark, The Pith: An Intensive Look at the Circulation
Rates of Primary Texts in Ten Major Literature Areas at the University of Oregon
Libraries
Authors: Staiger Jeff D.
Published: September 2021

This poster looks at the circulation rate for literary primary texts, which
constitute a unique area of collecting in academic libraries: while they do not in most
cases meet immediate research needs, it is assumed that libraries ought to acquire them,
for reasons including future research needs, preservation of the cultural record, and
the ability of members of the intellectual community to stay current, those these remain
primarily tacit. The circulation trends of contemporary literary works in ten areas of
literature (English, American, German, French, Italian, Spanish, Latin American,
Chinese, Japanese, and Russian) over the past twenty years at the University of Oregon
Knight Library are presented and the circulation turnover rate (CTR), for each of these
subject areas are presented. Sample graphs allow for the comparison of circulation rates
and numbers of books across time, and serve as examples of the utility of such
visualizations of the numbers. The key question raised by the study is what makes a good
CTR for a particular region of the collection? The poster concludes by summarizing the
considerations that bear on the interpretation of the CTR as an index of how the
collection is “working.”
The Time has Come for eBooks, or has it?
Authors: Wiersma Gabrielle , Beauchamp Leigh
Published: September 2021

For many years, librarians and industry experts predicted that electronic books
would surpass print books as the format of preference. The advantages that digital books
provide seemed to all but guarantee the demise of print. But something happened along
the way. Numerous studies during the last decade have demonstrated that print still has
a place for libraries, vendors and most importantly, end users. So what’s happened – why
hasn’t that time come like it has for journals? And will the “tipping point” for books
ever arrive? One explanation is that eBooks have not met user expectations, but
optimizing user experience when users range from students, to faculty, to librarians is
a big challenge! This session included a lively discussion about the user experience for
eBooks from multiple perspectives. Gabrielle Wiersma from the University of Colorado
Boulder shared findings from an eBook usability study with students and asked the
audience to consider the reasons why people prefer one format over another. Two graduate
students shared their perceptions and format preferences and answered questions from the
audience. Finally, Leigh Beauchamp, Vice President of Product Development discussed how
ProQuest is making patrons the center of Ebook Central platform development and how
eBooks are evolving to bring the most important elements of the print experience to
digital book research.

Published: September 2021

Academic libraries have increasingly recognized the need to collect diverse
materials. Simultaneously, academic libraries need to continue to develop additional
measures to evaluate collections for diversity as well as connect to collections to
their users and their campus initiatives and priorities. This paper features
perspectives from two academic libraries and shares how both are grappling with not only
assessing collections for the equity, diversity, and inclusivity, but also to place
those collection efforts in the broader picture of institutional values and

Chicago State University’s Gwendolyn Brooks Library decision to trial and acquire
Kanopy, A Patro-Driven-Acquisition video streaming service, was completely a
patron-demand-driven undertaking. The decision to obtain this service was led by faculty
interest in the resource and ranged from the initial inquiry for a trial by a foreign
language faculty member to its PDA model, which has allowed faculty to select the films
purchased. The article discusses the acquisition process, set-up steps for making the
trial and then the resource available to the CSU community, and the steps taken to

The Time Has Come... To Move Many Things: Inventorying and Preparing a Collection
for Offsite Storage
Authors: McLain Rachelle M. , McKelvey Hannah
Published: September 2021

In the spring of 2019, the Montana State University (MSU) Library embarked on a
large-scale inventory project that involved weeding and moving portions of their
collection to an offsite storage facility within six months in order to create more
student study space in the Library. The department primarily responsible for leading the
project, Collections Access & Technical Services, the result of two departments
merging, was also simultaneously navigating their new structure and a remodel of their
workspace thus adding further challenges to the project. This poster session
demonstrated how MSU Library approached and completed this project by advocating to
their Library Administration for additional resources, including hiring a project
manager and third-party companies to assist with the inventory and moving of the
collection. It also discussed the types of work groups formed to identify new workflows
(i.e., retrieval of offsite items) and modify existing ones, involving student employees
in the project, and internal and external collaborations that took place. Additionally,
presenters shared strategies used to communicate to their campus community, and the
impact this project has had on our patrons. They also included statistics that were
gathered during the project including deselection figures, the number of materials that
did not have barcodes and were not accounted for in the Library’s catalog and discovery
layer (Ex Libris’ Alma and Primo), and what subject areas currently remain in the main
library building.
Six Impossible Things: Moving KBART into the Next Decade
Authors: Rathemacher Andrée , Heaton Robert , Levin Noah , Stohn Christine
Published: September 2021

KBART is one of the most successful NISO recommendations today. Formally supported
by over 80 organizations across all stakeholder groups, it enables a standardized
transfer of data between content providers and knowledge bases. Most recently KBART
added an automated process to transfer holdings data to localize an institution’s
knowledge base holdings. While KBART was originally built to focus on journal and book
data, the world has moved on—the different flavors and nuances of open access, the
increased use of audiovisual material, holdings at the chapter and article levels, and
issues around translations, transliterations, and author names are just some of the
challenges that are disrupting the flow. So what is next for KBART? How does it adapt to
continue to solve the data flow problems that libraries, publishers, and knowledge base
providers face today? The presenters in this session, all members of the NISO KBART
Standing Committee and/or the KBART Automation Working Group, discuss the status and
future of a “Phase III” revision of NISO KBART that aims not only to clarify the
existing recommendations but also to expand them to address the new challenges,
including the support of additional content types beyond serials and monographs and
improvements to item-level discovery and access.

If there is one thing all library administrators and managers can be sure of, it
is that our space, our collections, our systems and our leadership will be impacted by
change. Managing that change is critical if managers, directors, deans in our libraries
will be able to continue to meet the needs of our communities with different tools and
resources. This lively discussion will feature brief presentations about how libraries
at Carnegie Mellon University and at Kresge Business Administration Library (University
of Michigan) have changed in recent history. The presenters will include what worked
well and what worked not as well at the two institutions. They will focus on two areas.
First, Denise Novak will explore change through five key aspects: nature, process, role,
culture and staff participation of change. Second, Corey Seeman will explore change as
defined by six key terms: inevitability, rapidity, flexibility, hospitality,
accountability, and empathy. Participants at the meeting will be invited to share how
change is managed at their institutions and what issues might be present or on the
horizon.

Uma abordagem baseada em redes neurais artificiais sobre o espectro de potência de eletroencefalogramas para o auxílio médico na classificação de crises epiléticas
Authors: Vargas Dionathan Luan de , Oliva Jefferson Tales , Teixeira Marcelo
Published: September 2021

A epilepsia é a quarta enfermidade neurológica mais comum e atinge aproximadamente 1% da população mundial. O diagnóstico é, em geral, amparado por um eletroencefalograma (EEG), cuja análise depende da interpretação médica, o que por vezes gera incongruência de diagnóstico, além de ser um trabalho tedioso, impreciso e propenso a erros. Este trabalho propõe um método de reconhecimento automático de padrões baseado em aprendizado de máquina e engenharia de características aplicadas ao espectros de potência de segmentos de EEGs. Resultados sugerem a possibilidade de detectar crises epilépticas com uma precisão superior a 80% em bases de dados já utilizadas na literatura.
Feasibility Study of MRI and Multimodality CT/MRI Radiomics for Lung Nodule Classification
Authors: Jatobá Anthony E. A. , Oliveira Marcelo C. , Koenigkam-Santos Marcel , Azevedo-Marques Paulo de
Published: September 2021

Lung cancer is the most common and lethal form of cancer, and its early diagnosis is key to the patient's survival. CT is the reference imaging scan for lung cancer screening; however, it presents the drawback of exposing the patient to ionizing radiation. Recent studies have shown the relevance of MRI in lung nodules diagnosis. In this work, we aimed to evaluate whether radiomics features from MRI are well-suited for lung nodules characterization and if the combination of CT and MRI features can yield better results than the features from the individual modalities. For such, we segmented paired CT and MRI nodules from 33 lung nodules patients, extracted 89 radiomics features from each modality, and combined it into a multimodality feature set. Those features were then used for classifying the nodules into benign and malignant by a set of machine learning algorithms, assessing the AUC across 30 trials. Our results show that MRI radiomics features are suitable for characterizing lung lesions, yielding AUC values up to 17% higher than their CT counterparts, and shedding light on MRI as a viable image modality for decision support systems. Conversely, our multimodality approach did not improve performance compared to the single-modality models, suggesting that the direct combination of multimodality features might not be an adequate strategy for dealing with multimodality medical images.

Even though vaccines are already in use worldwide, the COVID-19 pandemic is far from over, with some countries re-establishing the lockdown state, the virus has taken over 2 million lives until today, being a serious health issue. Although real-time reverse transcription-polymerase chain reaction (RTPCR) is the ﬁrst tool for COVID-19 diagnosis, its high false-negative rate and low sensitivity might delay accurate diagnosis. Therefore, fast COVID-19 diagnosis and quarantine, combined with effective vaccination plans, is crucial for the pandemic to be over as soon as possible. To that end, we propose an intelligent system to classify computed tomography (CT) of lung images between a normal, pneumonia caused by something other than the coronavirus or pneumonia caused by the coronavirus. This paper aims to evaluate a complete selfattention mechanism with a Transformer network to capture COVID-19 pattern over CT images. This approach has reached the state-of-the-art in multiple NLP problems and just recently is being applied for computer vision tasks. We combine vision transformer and performer (linear attention transformers), and also a modiﬁed vision transformer, reaching 96.00% accuracy.

Uma complicação causada pelo diabetes mellitus é o aparecimento de feridas situadas na região dos pés denominadasúlceras do pé diabético. O tratamento tardio pode acarretar o surgimento de infecção ou isquemia da úlcera que, em estado avançado, pode ocasionar a amputação dos membros inferiores. Neste trabalho foi realizado um comparativo do desempenho de diversas arquiteturas de aprendizado profundo pré-treinadas na classiﬁcação de imagens deúlceras do pé diabético. Nossa avaliação levou em consideração quatro cenários, três binários Saudável vs Úlceras; Saudável vs Isquemia; Saudável vs Infecção e um multiclasse Saudável vs Úlcera vs Isquemia vs Infecção vs Infecção e Isquemia. Os resultados alcançados demostram que a nossa proposta consegue classiﬁcar tais imagens, visto que, nos testes realizados o índice Kappa atingiu valores considerados "Excelentes". Contudo, para o problema multiclasse ainda é necessário aprimorar o uso dessas técnicas.

Embolia pulmonar é uma das principais causas de morte relacionadas a doenças cardiovasculares no mundo, uma vez que é feito o diagnostico é necessária uma resposta rápida pela equipe médica para salvar o paciente. A principal forma de diagnóstico é pelo exame de tomograﬁa computadorizada e, devido a grande quantidade de dados que o exame gera, algoritmos de deep learning têm mostrado bons resultados em encontrar embolia pulmonar de maneira autônoma. O objetivo deste trabalho é desenvolver uma rede de deep learning capaz de encontrar embolia pulmonar em exames de tomograﬁa computadorizada. Até então, utilizando uma rede inspirada na U-net, o método segmentou trombos atingindo um Dice Score de 0.81 e um IoU de 0.79.

Existem barreiras burocráticas e de ideais que tornam a comparação de departamentos e identiﬁcação de padrões, em geral, tarefas difíceis. A exploração dos dados coletados, juntamente com um modelo descritivo induzido a partir desses dados, podem ajudar a identiﬁcar modelos destoantes e promover a comparação das instituições. O estudo propõe a criação de modelos de redes Bayesianas capazes de representar e extrair conhecimentos novos e signiﬁcativos a partir dos dados nas variáveis utilizadas no estudo de caso. São selecionadas variáveis sobre secções obstétricas de hospitais de Portugal para a criação do modelo de cada entidade/secção. As funções do pacote R "bnlearn" foram usadas para manipular e recriar dados no modelo. O desempenho deste modelo foi validado quanto à capacidade de recriar dados. Para construir uma matriz de distâncias entre modelos para identiﬁcação de entidades destoantes, a distância de Hamming. As anomalias detectadas pela comparação dos modelos criados foram validadas por especialista de acordo com a escala Likert. Os dados foram descritos e recriados através de redes Bayesianas com imputação de dados, com referência signiﬁcativa aos dados reais. A comparação dos modelos sobre as secções de obstetrícia identiﬁcou padrões e anomalias. A comparação permitiu diferenciar os setores com diferentes taxas de cesárea e distribuição nos grupos de Robson, de acordo com as variáveis selecionadas, preservando o acesso aos dados reais das instituições.

Studies published in the literature indicate that the use of multimedia content improves the reading performance of students with dyslexia. However, most multimedia applications use only two of the ﬁve human senses. MBook, a multisensory book developed for this work, uses an eye tracker to synchronize wind, smell, sounds, and light effects to the text being read. It was based on the hypothesis that a multisensory reading could reduce the overload in working memory, thus improving comprehension. Experimental results point to a gain in text comprehension and an increase in reading speed by the student with dyslexia when multisensory media were used. Also, the use of the tool pointed to an increase in reading motivation.

A leucemia é um tipo de câncer que afeta a produção de células sanguíneas na medula óssea o que diﬁculta a coagulação do sangue e o combate a infecções. Nesse trabalho propomos um método para o diagnóstico automático de leucemia utilizando Redes Neurais Convolucionais (CNNs). Nós utilizamos CNNs pré-treinadas e técnicas de transferência de aprendizagem na construção do método proposto. Empregamos a técnica modiﬁed Deeply Fine Tuning (mDFT) combinada com operações de aumento de dados para reﬁnar um modelo pré-treinado. Para treinar e testar o método proposto, utilizamos um conjunto de 3.536 imagens de 18 bases diferentes. A técnica de validação Leave-One-Dataset-Out Cross-Validation (LODOCV) foi proposta para avaliar a capacidade de generalização do modelo. Os principais resultados obtidos utilizando o LODOCV em três bases de dados foram 97,04, 82,46 e 70,24% de acurácia.
