description: The study evaluated the feasibility of applying computational intelligence methods as a non-destructive technique in describing the drying behaviour of persimmon fruit using vacuum drying (VD) and hot-air-drying (HAD) methods and to compare the results with thin layer mathematical models. Drying temperatures were 50, 60 and 70 °C. Kinetic models were developed using semi-theoretical thin layer models and computational intelligence methods: multi-layer feed-forward artificial neural network (ANN) and support vector regression (SVR). The statistical indicators of coefficient of determination (R2 ) and root mean square error (RMSE) were used to assess the suitability of the models. The thin-layer mathematical models namely page and logarithmic accurately described the drying kinetics of persimmon slices with the highest R2 of 0.9999 and lowest RMSE of 0.0031. ANN showed R2 and RMSE values of 1.0000 and 0.0003, while SVR showed R2 of 0.9999 and RMSE of 0.0004. The validation results indicated good agreement between the predicted values obtained from the computational intelligence methods and the experimental moisture ratio data. Based on the study results, computational intelligence methods can reliably be used to describe the drying process of persimmon fruit.

description: Through statewide, national and international programs (i.e., the Statewide Land cover And Trees Study (SLATS), the Terrestrial Ecosystem Research Network (TERN) Auscover project and the Japanese Space Exploration Agency (JAXA) Kyoto and Carbon (K&C) Initiative), statewide to national scale moderate spatial resolution products relating to fractional cover and persistent green cover, vegetation height and structure, and above ground biomass have been generated separately using time-series of Landsat sensor data, ICESat GLAS and ALOS PALSAR data. However, the combination of these data to enhance retrieval of vegetation biophysical properties has been limited (e.g., to mapping of regrowth stage through integration of ALOS PALSAR and Landsat-derived cover estimates. This research therefore investigated the potential benefits of integrating these data through object-based analysis. Focusing on the Injune Landscape Collaborative Project (ILCP) research area in Queensland, co-registered Landsat Foliage Projected Cover (FPC) and ALOS PALSAR L-band HH and HV mosaics were segmented to generate objects with similar radar backscatter and cover characteristics. Within these, height, cover, age class and L-band backscatter characteristics were summarised based on the ICESat and Landsat time-series and ALOS PALSAR datasets. The study established the complimentarity of the datasets (e.g., in terms of retrieving biophysical properties) and, through validation against ground truth data (obtained through field and airborne lidar data collection), potential for significant improvement in the retrieval of extent, height and cover. Future research is focusing on expanding the use of these combined datasets at a regional level with a view to developing operational methods to support policy and decision-making across government and non-government organisations.

description: Background: As in other eukaryotes, plant mitogen-activated protein kinase (MAPK) cascades are composed of three classes of hierarchically organized protein kinases, namely MAPKKKs, MAPKKs, and MAPKs. These modules rapidly amplify and transduce extracellular signals into various appropriate intracellular responses. While extensive work has been conducted on the post-translational regulation of specific MAPKKs and MAPKs in various plant species, there has been no systematic investigation of the genomic organization and transcriptional regulation of these genes. Results Ten putative poplar MAPKK genes (PtMKKs) and 21 putative poplar MAPK genes (PtMPKs) have been identified and located within the poplar (Populus trichocarpa) genome. Analysis of exon-intron junctions and of intron phase inside the predicted coding region of each candidate gene has revealed high levels of conservation within and between phylogenetic groups. Expression profiles of all members of these two gene families were also analyzed in 17 different poplar organs, using gene-specific primers directed at the 3'-untranslated region of each candidate gene and real-time quantitative PCR. Most PtMKKs and PtMPKs were differentially expressed across this developmental series. Conclusion This analysis provides a complete survey of MAPKK and MAPK gene expression profiles in poplar, a large woody perennial plant, and thus complements the extensive expression profiling data available for the herbaceous annual Arabidopsis thaliana. The poplar genome is marked by extensive segmental and chromosomal duplications, and within both kinase families, some recently duplicated paralogous gene pairs often display markedly different patterns of expression, consistent with the rapid evolution of specialized protein functions in this highly adaptive species.
Internal structure of verb meaning: A study of verbs of (change of) state in Tamazight (Berber)
Creators: name: Achab, Karim
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: Language, Linguistics.

description: The dissertation investigates verbs of (change of) state in Tamazight (Berber) from the perspective of their internal structure and its syntactic corollary, which corresponds to predicate-argument structure. The verbs investigated include verbs of quality, unaccusatives, spatial configuration verbs, and causatives. Verbs of quality refer to a special class of intransitive verbs occurring with accusative clitics when they indicate a pure state, and with nominative clitics when they indicate change of state. In the latter situation verbs of quality are undistinguished from unaccusatives. I argue that while nominative clitics associated with verbs of quality surface in the subject position for EPP reasons, accusative clitics surfaces in the object position because the category T involved is defective, following an idea proposed by Chomsky (2001). This contradicts the view in Government and Binding Theory that intransitive verbs do not assign unaccusative Case. I sustain that the pure state form has a monadic structure of the type [VBE[√ROOT]], while the inchoative form, like unaccusatives, is associated with the dyadic structure of the type [VCOME[V BE[√ROOT]]]. To account for the two different interpretations associated with the inchoative form I argue that its syntactic structure contains a scope operator with two different positions. When the operator has scope over VCOME, it yields change of state interpretation; when the operator has scope over VBE, the interpretation is stative (resultative). Verbs of quality and unaccusatives are contrasted with verbs of spatial configuration which are analyzed as disguised reflexives, with a triadic structure of the type [VACT[VCOME[VBE([√ROOT])]]]. The reflexive interpretation results from the association of the internal argument with two thematic positions [Spec,VACT] and [Spec,V COME]. The structure postulated for causatives is of the type [VCAUSE [COME[VBE([√ROOT])]]]. I argue that lexical causatives have a basic structure while morphological causatives are derived by augmenting their unaccusative counterpart. Lexical causatives are of two types. I argue that those lacking the unaccusative alternate have their lexical root conflated with the verb CAUSE, while unaccusative-alternating causatives have their lexical root conflated with the lower verbs (BE)COME. This idea is extended to account for the difference between unaccusative-alternating and non-alternating languages.
An optimality theoretic approach to variable consonantal alternations in Qatari Arabic
Creators: name: Mustafawi, Eiman M
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: Language, Linguistics.

description: This thesis investigates two variable phonological processes exhibited in Qatari Arabic (QA). The first is the affrication of the velar stops [k] and [g] to [t∫] and [d3], respectively, a process that has been traditionally assumed to be triggered by adjacency to a front vowel. The second alternation concerns the lenition of /d3/ to [j], taken to be phonetically unconditioned. Previous studies, however, recognize the existence of a large number of exceptions to these processes. By reconsidering the data in the light of new advancements in phonological theory, affrication and lenition are analyzed as regular processes, and cases that were previously considered to be exceptions to affrication and lenition are accounted for. I find that affrication can be triggered only by adjacency to [i(:)], to the exclusion of any other segment, within the stem. Also, affrication interacts with pharyngealization, a process that retracts/lowers vowels in a certain domain and removes the required context for affrication to apply. Lenition is argued not to be context-free, as it is blocked in coda position preceded by a non-low vowel, as well as in geminates. Exceptions to lenition are accounted for by employing the notion of prespecification/underspecification. Both processes are subject to OCP restrictions and paradigmatic effects. Typologically, the current study adds QA to the small list of languages in which lenition of an obstruent to a glide applies. It also provides evidence for considering the OCP a synchronically active constraint in Arabic, restricting segmental alternation, in addition to restricting static patterns of phonological representation. I also argue for the inclusion of the segments /g/ and /t∫/, which are traditionally assumed to derive from an underlying /q/ and /k/, respectively, in the phonemic inventory of QA. The discussion is based on a large amount of data, extracted from a local dictionary and complemented by additional forms provided by the author. The analysis is cast in an optimality theoretic (OT) framework (Prince & Smolensky, 2004), which holds that linguistic forms are the outcome of the interaction among violable universal constraints, and in OT's recent development into a model that accounts for linguistic variation.

Harnessing Environmental Justice to Protect Against Land-grabbing in Cameroon

description: I am submitting this thesis to the Faculty of Law, the University of Ottawa in fulfillment of the requirements for the Degree of Doctor of Philosophy (Ph.D.) in August 2016. The thesis examined the issue of land-grabbing through an environmental justice lens. The thesis first reviewed the concept of environmental justice and the threats that land-grabbing by powerful transnational corporations pose to subsistence communities in Africa. Additionally, this study investigated the adequacy of international guidelines to regulate against land-grabbing, including the Minimum Human Rights Principles, the Voluntary Guidelines on the Responsible Governance of Tenure, and the Principles for Responsible Agricultural Investments. Using Cameroon as my case study, the study also examined the adequacy of Cameroon’s land tenure rules and environmental impact assessment (EIA) system to protect vulnerable communities against land-grabbing. Drawing on examples from Cameroon, Ethiopia, Ivory Coast, Mozambique, Nigeria, Senegal, Tanzania, and Uganda, this thesis argues that subsistence communities who failed to have their customary land rights formalized or failed to adequately participate in environmental decision-making end up dispossessed of their means of surviving and thriving. There were three key findings: first, international guidelines regulating against global land-grabbing lack the binding force to coerce host states to take the necessary action to enforce the guidelines and, hence promote responsible agricultural investments. Next, the land rights of subsistence Cameroonians are not formally recognized under Cameroon`s land tenure system, making it difficult for vulnerable populations to contest these allocations or receive compensation in the event of expropriation. Thirdly, EIA follow-up in Cameroon is driven entirely by the investor: the EIA system does not encourage a joint follow-up activity initiated by all groups of stakeholders involved in EIA. Without an independent environmental oversight body that can provide expert evaluation and monitor the Cameroon government and (agricultural) corporations, there is no guarantee that proposed mitigation measures will be translated into specific actions by Herakles Farms. Based on the evaluation results, the following recommendations are made to the Cameroon Government to promote environmental justice in communities that are vulnerable to land-grabbing: (1) formalize customary land tenure, (2) promote environmental contracting; (3) encourage sustainability assessments.

description: Background: Many cases of frontotemporal dementia (FTD) are familial, often with an autosomal dominant pattern of inheritance. Some are due to a mutation in the tau- encoding gene, on chromosome 17, and show an accumulation of abnormal tau in brain tissue (FTDP-17T). Most of the remaining familial cases do not exhibit tau pathology, but display neuropathology similar to patients with dementia and motor neuron disease, characterized by the presence of ubiquitin-immunoreactive (ub-ir), dystrophic neurites and neuronal cytoplasmic inclusions in the neocortex and hippocampus (FTLD-U). Recently, we described a subset of patients with familial FTD with autopsy-proven FTLD-U pathology and with the additional finding of ub-ir neuronal intranuclear inclusions (NII). NII are a characteristic feature of several other neurodegenerative conditions for which the genetic basis is abnormal expansion of a polyglutamine-encoding trinucleotide repeat region. The genetic basis of familial FTLD-U is currently not known, however the presence of NII suggests that a subset of cases may represent a polyglutamine expansion disease. Methods: We studied DNA and post mortem brain tissue from 5 affected members of 4 different families with NII and one affected individual with familial FTLD-U without NII. Patient DNA was screened for CAA/CAG trinucleotide expansion in a set of candidate genes identified using a genome-wide computational approach. Genes containing CAA/CAG trinucleotide repeats encoding at least five glutamines were examined (n = 63), including the nine genes currently known to be associated with human disease. CAA/CAG tract sizes were compared with published normal values (where available) and with those of healthy controls (n = 94). High-resolution agarose gel electrophoresis was used to measure allele size (number of CAA/CAG repeats). For any alleles estimated to be equal to or larger than the maximum measured in the control population, the CAA/CAG tract length was confirmed by capillary electrophoresis. In addition, immunohistochemistry using a monoclonal antibody that recognizes proteins containing expanded polyglutamines (1C2) was performed on sections of post mortem brain tissue from subjects with NII. Results: No significant polyglutamine-encoding repeat expansions were identified in the DNA from any of our FTLD-U patients. NII in the FTLD-U cases showed no 1C2 immunoreactivity. Conclusion: We find no evidence to suggest that autosomal dominant FTLD-U with NII is a polyglutamine expansion disease.

description: Spreadsheets are widely used in industry, because they are flexible and easy to use. Often they are used for business-critical applications. It is however difficult for spreadsheet users to correctly assess the quality of spreadsheets, especially with respect to the understandability. Understandability of spreadsheets is important, since spreadsheets often have a long lifespan, during which they are used by several users. In this paper, we establish a set of spreadsheet understandability metrics. We start by studying related work and interviewing 40 spreadsheet professionals to obtain a set of characteristics that might contribute to understandability problems in spreadsheets. Based on those characteristics we subsequently determine a number of understandability metrics. To evaluate the usefulness of our metrics, we conducted a series of experiments in which professional spreadsheet users performed a number of short maintenance tasks on a set of spreadsheets from the EUSES spreadsheet corpus. The results of these tests clearly indicate that the number of ranges, the nesting depth and the presence of conditional operations in formulas significantly increase the difficulty of understanding a spreadsheet.
Characterization of the role of neuromedin B and gastrin-releasing peptide in the mediation of stress and anxiety-related responses

description: The perception of an event as being potentially harmful or stressful to the individual sets off a cascade of responses, including the activation of neurons located in the hypothalamus. Despite the extensive efforts in understanding the various neurochemical systems regulating this cascade of events, many questions remain unanswered concerning the underlying mechanisms involved. Evidence from our laboratory suggests involvement of bombesin (BB; a peptide of amphibian origin), in the mediation and/or modulation of the stress response. Two BB-like peptides have been identified in mammals, gastrin-releasing peptide (GRP) and neuromedin B (NMB). Experimental evidence acquired thus far seems to suggest the potential involvement of BB-like peptides in the mediation of the stress response as well as other related responses, such as fear and anxiety. However, very few experiments have focused on determining the specific roles of NMB and GRP in mechanisms underlying the integration of stress and/or anxiety responses. Thus, the overall objective of this thesis is to clarify the intrinsic role of each of these peptides in the hope of gaining a better understanding of the underlying mechanisms mediating stress-related responses. This extensive research project provides new evidence suggesting that both endogenous BB-like peptide systems, GRP and NMB, are significantly involved in the modulation/facilitation of stress-, anxiety- and/or fear-related behaviors. Their intrinsic roles appear to be different; whereas NMB seems to mediate both anxiety and fear, GRP seems to selectively alter more robust stress-related behaviors, such as fear. This thesis project provides important additional support for the involvement of this family of peptides in stress related responses. It also provides interesting insight into the different mechanism(s) of action that might underlie stress, anxiety and/or fear. This new evidence should help in the development of more specific, and therefore efficient, therapeutic agents in the prevention and treatment of stress-related disorders.

The transcription factor ATF3 is upregulated during chondrocyte differentiation and represses cyclin D1 and A gene transcription

description: Background: Coordinated chondrocyte proliferation and differentiation are required for normal endochondral bone growth. Transcription factors binding to the cyclicAMP response element (CRE) are known to regulate these processes. One member of this family, Activating Tanscription Factor 3 (ATF3), is expressed during skeletogenesis and acts as a transcriptional repressor, but the function of this protein in chondrogenesis is unknown. Results: Here we demonstrate that Atf3 mRNA levels increase during mouse chondrocyte differentiation in vitro and in vivo. In addition, Atf3 mRNA levels are increased in response to cytochalasin D treatment, an inducer of chondrocyte maturation. This is accompanied by increased Atf3 promoter activity in cytochalasin D-treated chondrocytes. We had shown earlier that transcription of the cell cycle genes cyclin D1 and cyclin A in chondrocytes is dependent on CREs. Here we demonstrate that overexpression of ATF3 in primary mouse chondrocytes results in reduced transcription of both genes, as well as decreased activity of a CRE reporter plasmid. Repression of cyclin A transcription by ATF3 required the CRE in the cyclin A promoter. In parallel, ATF3 overexpression reduces the activity of a SOX9-dependent promoter and increases the activity of a RUNX2-dependent promoter. Conclusion: Our data suggest that transcriptional induction of the Atf3 gene in maturing chondrocytes results in down-regulation of cyclin D1 and cyclin A expression as well as activation of RUNX2-dependent transcription. Therefore, ATF3 induction appears to facilitate cell cycle exit and terminal differentiation of chondrocytes.

description: L'itinérance est imbibée de préconceptions et de préjugés : " les itinérants sont des personnes qui choisissent de ne pas travailler ", " ce sont des lâches ", etc. Suite à des expériences professionnelles et personnelles avec des personnes en situation d'itinérance, nous nous sommes intéressée à leur histoire. Concrètement, les questions qui guident notre recherche sont : 1) Quelles perceptions les itinérants ont-ils du processus et de la trajectoire qui les ont amenés à la rue? Et 2) Comment ces personnes errantes vivent-elles leur expérience " itinérante "? Nous avons ainsi été en mesure de retracer les perceptions de sept personnes fréquentant des organismes communautaires du côté de Gatineau sur leurs trajectoires itinérantes. Malgré le fait qu'ils aient tous un " profil " bien différent, les itinérants interrogés partagent certains éléments en commun. Les théories de l'exclusion proposées par Castel (1994, 1995), De Gaulejac et Taboada Leonetti (1994) ainsi que Paugam (2002) permettent de comprendre le processus similaire dans lequel chacun passe lors de ses " épisodes " d'itinérance. Trois thèmes centraux sont ressortis de nos entretiens avec des personnes qui ont vécu un ou des épisodes d'itinérance : 1) le rapport avec le temps, 2) le rapport avec l'espace "public" et " communautaire ", et 3) le rapport avec les autorités. Tout d'abord, le temps " itinérant " et le temps " carcéral " sont fort similaires : un itinérant et un détenu doivent inévitablement " tuer le temps ". Ensuite, l'espace public est un espace transitoire. Nul ne doit " abuser " de cet espace : en particulier, les personnes ne disposant pas de propriété privée. Enfin, les institutions communautaires ont peut-être de bonnes intentions initiales et/ou manifestes vis-à-vis de leur clientèle, mais en fin de compte, leur ambition semble surtout se limiter à garantir la survie de cette population voire... à l'entretenir. Paradoxalement, en effet, ces institutions pourraient finalement " servir " à immobiliser (spatialement et socialement) leurs clients.

description: Since 2017 multiple ovulation (MO) and embryo transfer (ET) were used to save endangered cow breeds in Latvia. The aim of this work was to analyse results to establish factors influenced recipients’ pregnancy obtained up to now. Recipients age, induced (IRC) or native reproductive cycle (NRC), level of estradiol (E2) and progesterone (P4) in recipients’ blood on ET day, stage and quality of embryo, fresh or thawed embryo usage and person provided ET were taken into account. Repeated artificial insemination (AI) had been provided in 19 (22.1%) recipients before ET. Pregnancy was accepted in 23 out of 76 recipients (30.3%) until now. Higher pregnancy results were obtained using fresh embryos (19 out of 53 (35.8%)) vs thawed embryos (4 out of 23 (17.4%)), (P < 0.05). The IRC was more productive than NRC (P < 0.05). The development stage, quality of embryos, E2 level were significant factors to reach pregnancy (P < 0.05) but recipients age, P4 level and person provided ET did not influence the pregnancy rate in the present study (P > 0.05). More successful pregnancies were reached using embryos obtained from donors which had a higher glucose and cholesterol level in blood (P = 0.05). In conclusion, our newly educated MOET team should gain their experience and results could be improved using IRC in recipients, fresh embryos, and more attention could be paid to the donorcows management in order to reach more qualitative embryos. Somatic cell count in the donors’ milk could be one of the indicator to avoid unsuccessful embryo obtaining.

description: Recent advances in portable computing devices and wireless technology make it possible to provide seamless and ubiquitous services for mobile users. As users move from one location to another, there is a greater need to automatically provide office-like environments that normally have to be configured and setup on an individual basis by each user at each visited location. Due to occasional disconnections, device capabilities and network heterogeneity, users' mobility places a considerable burden on applications to be used by mobile users. On the other hand, it receives little assistance from existing infrastructure and Internet protocols for tracing users' movement and adapting services to satisfy unique characteristics of mobility. This thesis recognizes the importance of managing users' mobility at different levels. From the network level by monitoring network devices and access points to the organizational level by assigning a personalised profile and a specific role to mobile users at visited locations. We propose a set of policy-based agents composing a framework that assists applications and services in dealing with mobility challenges and capable of providing a mobile working environment, similar to the home or office environment, to be used by users wherever they travel and whichever devices they use. The framework enables application designers to more easily build complex mobile and context aware applications. It also provides some basic services so that it can help mobile users simply by making use of the existing support and built in policy-based software agents. In addition, three different applications built upon the framework along with various scenarios have been discussed. Various scenarios illustrate how the framework can be helpful in providing support and services to mobile users. The framework is also a test-bed platform that can be used for the ongoing and future research projects that make use of mobility and context-awareness in MMARL laboratory.

description: Environmental estrogenic compounds which bind to the estrogen receptor (ER) can block or alter endogenous functions of estrogen in reproductive and developmental stages. A microarray technology is a very valuable method for the prediction of hormone-responsive activities in various gene expressions. Thus, we investigated the altered gene expression by estrogen and endocrine disruptors (EDs) using microarray technology in the uterus of immature rats. In this study, the expression levels of only 555 genes (7.42%) among the 7636 genes spotted on microarray chips were enhanced by more than two-fold following treatment with estradiol (E2), suggesting that direct or rapid response to E2 is widespread at the mRNA levels in these genes. In addition, elevated expression levels of the genes (over 2-fold) were observed by diethylstilbestrol (DES; 9.01%), octyl-phenol (OP; 8.81%), nonyl-phenol (NP; 9.51%), bisphenol-A (BPA; 8.26%) or genistein (9.97%) in the uterus of immature rats. The expression levels of representative genes, i.e., calbindin-D9k (CaBP-9k; vitamin D-dependent calcium-binding protein), oxytocin, adipocyte complement related protein (MW 30 kDa), lactate dehydrogenase A and calcium binding protein A6 (S100a6; calcyclin), were confirmed in these tissues by real-time PCR. In addition, the mRNA levels of these genes by real-time PCR were increased at follicular phase when E2 level was elevated during estrous cycle of adult female rats. In conclusion, these results indicate distinct altered expression of responsive genes following exposure to E2 and estrogenic compounds, and implicate distinct effects of endogenous E2 and environmental endocrine disrupting chemicals in the uterus of immature rats.

description: This paper aimed to analyze the magnitude and spatial variability of environmental variables: Temperature and Relative Humidity Index (THI), Radiant Thermal Load (RTL), Globe Temperature and Relative Humidity Index (BGTH) and Enthalpy (H), inside a house for laying hens, in the state of Antioquia (Colombia) during the month of August. A traditional Colombian poultry house with natural ventilation was used. All variables were manually measured at equally spaced 1.0×1.0 m points, totaling 99 data collection points inside the poultry house. Geostatistical techniques were used through semivariogram analysis, and isochore maps were generated through data interpolation by kriging. The semivariogram was fitted by the restricted maximum likelihood method. The used mathematical model was the spherical one. After adjusting the semivariograms, the data were interpolated by ordinary kriging. The semivariograms and the isochore maps allowed identifying the non-uniformity of the spatial distribution of all evaluated variables throughout the poultry house. The results show that THI, RTL, BGTH and, H presented values above the comfort limits in the most significant part of the poultry house during the observed period. It is possible to concluded that the use of natural ventilation alone was not sufficient to guarantee the homeothermy conditions for the layers. Thus, it is suggested that in addition to natural ventilation, secondary modifications should be used to improve farm productivity.
ASCE steel bridge competition

Publisher: name: Unknown
Year: 2017

description: A steel bridge was constructed to participate in the 2017 American Society of Civil
Engineers (ASCE) Great Lakes Student Conference (GLSC) competition. The bridge was
designed in compliance with the AISC Steel Manual 14''^ Edition. Calculations were tabulated
and formatted into an Excel design aid which will be useful for future designs. Checks were done
for each failure mode specified for beam flexure, lateral-torsional buckling, connections, and
column buckling. The bridge was fabricated in the Applied Engineering Center (AEC) on the
University of Southern Indiana's campus. This project made extensive use of the previously
unused robotic welder. The bridge was load tested at the University after the Competition and
began to fail due to yielding in the tension flange which would have rapidly led to block shear.

description: Because of different Brazilian climatic conditions and the different plant conditions, such as the stage of development and even the variety, wide variation may exist in the crop coefficients (𝐾𝑐) values, both spatially and temporally. Thus, the objective of this study was to develop a methodology to determine the short-term 𝐾𝑐 using biophysical parameters of coffee plants detected images obtained by an Unmanned Aircraft System (UAS). The study was conducted in Travessia variety coffee plantation. A UAS equipped with a digital camera was used. The images were collected in the field and were processed in Agisoft PhotoScan software. The data extracted from the images were used to calculate the biophysical parameters: leaf area index (LAI), leaf area (LA) and 𝐾𝑐. GeoDA software was used for mapping and spatial analysis. The pseudo-significance test was applied with p < 0.05 to validate the statistic. Moran's index (I) for June was 0.228 and for May was 0.286. Estimates of 𝐾𝑐 values in June varied between 0.963 and 1.005. In May, the 𝐾𝑐 values were 1.05 for 32 blocks. With this study, a methodology was developed that enables the estimation of 𝐾𝑐 using remotely generated biophysical crop data.

description: Precision agriculture (PA) provides techniques that favour the localized application of inputs allowing their rational use. This makes the PA a potential indicator of reduced operational costs, input volume, and environmental impacts. The objective of this study was to evaluate and compare the environmental effects of three different sampling methods used in PA for the lime application. The first sampling method evaluated was the grid sampling (GS). It was performed at a density of one sample per hectare in a 100×100 m georeferenced grid. The second method was the directed sampling, that was performed after defining the management zones by soil apparent electrical conductivity (ECa) using a soil electrical conductivity sensor. The lest sampling method was the Altitude-based management zone (AMZ) sampling that was developed based on altitude maps of the field. These sampling methods were tested in three different areas in the south of Brazil. This study evaluated the spatial variability of the lime volume in the soil and compared quantitatively and spatially the recommended application volumes achieved by each sampling method. Results highlighted that the sensor-directed soil sampling method was the alternative that would generate the lowest environmental impact.

description: Precise spatial and temporal manipulation of neural activity in specific genetically defined cell populations is now possible with the advent of optogenetics. The emerging field of optogenetics consists of a set of naturally-occurring and engineered light-sensitive membrane proteins that are able to activate (e.g., channelrhodopsin-2, ChR2) or silence (e.g., halorhodopsin, NpHR) neural activity. Here we demonstrate the technique and the feasibility of using novel adeno-associated viral (AAV) tools to activate (AAV-CaMKllα-ChR2-eYFP) or silence (AAV-CaMKllα-eNpHR3.0-eYFP) neural activity of rat prefrontal cortical prelimbic (PL) pyramidal neurons in vivo. In vivo single unit extracellular recording of ChR2- transduced pyramidal neurons showed that delivery of brief (10 ms) blue (473 nm) light-pulse trains up to 20 Hz via a custom fiber optic-coupled recording electrode (optrode) induced spiking with high fidelity at 20 Hz for the duration of recording (up to two hours in some cases). To silence spontaneously active neurons we transduced them with the NpHR construct and administered continuous green (532 nm) light to completely inhibit action potential activity for up to 10 seconds with 100% fidelity in most cases. These versatile photosensitive tools combined with optrode recording methods provide experimental control over activity of genetically defined neurons and can be used to investigate the functional relationship between neural activity and complex cognitive behavior.

Searching for IRES

description: The standard method of translation initiation, where the ribosome binding onto mRNA is mediated by initiation factors that congregate at the 5' "cap-nucleotide" of the RNA, is at times, partially disabled. For example, during viral infection, mitosis, and cellular stress, the efficiency of this form of initiation is reduced relative to an alternate mechanism of initiation that utilizes Internal Ribosome Entry Sites (IRESes) contained in the 5' UTR sequence of viral and cellular RNA transcripts. These IRESes often are bound by non-canonical initiation factors that help to recruit the ribosomes to the mRNA upstream of the start codon without the need of a 5' cap structure. In viral IRESes, Eke HCV and EMCV, RNA structures have been shown to be critical for IRES function. These structures are also similar in other viruses that do not share sequence similarity. HCV for example, is similar to CSFV and BVDV, while the EMCV IRES structure is shared with other cardio-picornaviruses. In contrast, although several cellular IRESes' RNA secondary structures have been determined, no similarities have yet been identified. In order to establish if structure similarities could be found in cellular IRESes, the secondary structure of the X-linked inhibitor of apoptosis (XIAP) IRES was determined and used for an in silico search of all human 5' UTRs using the RSEARCH program. Five of the top computational matches were cloned and tested for IRES activity in beta-Gal/CAT bicistronic constructs. Of these, the 5' UTRs from Aquaporin 4 and the uncharacterized ELG1 transcripts exhibited IRES activity although at a much lower level than that of the MAP IRES. The actual RNA secondary structure of the ELG1 IRES did not match the predicted match from RSEARCH but the AQP4 IRES had a similar structure surrounding a polypyrimidine tract. Importantly, deletion of this motif removed all IRES activity similar to the analogous polypyrimidine tract deletion of the XIAP IRES. As only a slight similarity was found, it seems that RNA structures of IRESes in cellular messages are not shared and do not play the same role as those in viral mRNAs.
