title: DCSM Sleep Staging Dataset

description: --| Overview This archive stores the Danish Center for Sleep Medicine (DCSM) sleep staging dataset. The DCSM dataset consists of 255 randomly selected and fully anonymized overnight lab-based PSG recordings from patients visiting the DCSM for the diagnosis of non-specific sleep related disorders. The DCSM dataset represents a diverse cohort of Danish patients with respect to demographic characteristics, diagnostic background and sleep/non-sleep related medication usage. The PSGs were collected between 2015-2018. EEG and EOG signals were recorded at 256 Hz and bandpass filtered to the interval 0.3 Hz - 70 Hz (3dB limits). Hypnograms were scored according to the AASM criteria. The intended purpose of the DCSM dataset is development and benchmarking of clinically applicable sleep staging algorithms. --| Publication This dataset was published in: U-Sleep: Resilient High-Frequency Sleep Staging Mathias Perslev, Sune Darkner, Lykke Kempfner, Miki Nikolic, Poul Jørgen Jennum and Christian Igel npj Digital Medicine, 2021 --| Dataset Structure Each subject in the dataset is represented by an anonymously named folder storing three data files, 'hypnogram.ids', 'psg.edf' and 'psg.h5', for example: /dcsm_dataset/ |- tp8cbd54f0_4751_4def_b11e_6e6353c69562 |----| hypnogram.ids |----| psg.edf |----| psg.h5 ---| Downloading the Data The dataset can be downloaded as a single zip file from this archive. Alternatively, the U-Time software package allows the entire or a subset of the dataset to be downloaded. Please see https://github.com/perslev/U-Time ---| Loading Data Data may be loaded manually (please refer to details below) or using the U-Time software package. Please see to https://github.com/perslev/U-Time. ---| H5 & EDF PSG File Details Each PSG file (psg.h5) is a HDF5 formatted file storing data from multiple modalities such as EEG, EOG and EMG as separate channel-wise entries. The archive stores each channel under a group named 'channels'. For example, to access data channel 'C3-M2', the directory '/channels/C3-M2' should be considered. Each archive also has the attributes 'date' and 'sample_rate': 'date' is always None (anonymized) and 'sample_rate' is always 256 (Hz). Each PSG recording is also supplied in EDF format. ---| Hypnogram File Details Each hypnogram file (hypnogram.ids) is a text file storing data in "init-duration-stage" format (ids). It contains three comma-separated columns of values: 1) The first column ('init') stores a time point at which a scored segment of sleep begins in seconds offset from the start of the PSG recording. 2) The second column ('duration') stores the duration of time in seconds that the scored segment of sleep lasts. 3) The third column ('stage') stores the clinician's sleep stage annotation for the segment, which is always one of ['Wake', 'N1', 'N2', 'N3', 'REM']. For example, if a subject was scored to be in sleep stage "Wake" for 120 seconds starting at second 60 in the file, the hypnogram file would contain the following line: "60,120,Wake".

title: Losses of water, soil, and nutrients during high-intensity simulated rainfall in two soil management systems different sources of fertilization

description: ABSTRACT: The goal of this study was to quantify the water, soil, and soluble nutrient losses during high-intensity rainfall simulated in two soil preparation systems with four sources of fertilization. Forty-five days after the corn seeding, a 120 mm h-1 intensity rainfall was simulated during 90 min in field plots with conventional tillage (CT) or no-tillage (NT). Each system had four repetitions with the fertilizer treatments, including without fertilization, mineral, urban waste compost (UWC), and pig slurry. P, K, Ca, and K concentrations were measured in soluble form, in addition to electrical conductivity, pH, water, and soil losses. As expected, the greatest soil losses occurred with CT; however, the greatest water losses occurred with NT. Among the fertilizers, UWC was more efficient because it had the highest infiltration rates. The concentrations of P, K, Ca, and Mg did not exhibit any interaction between fertilization and soil tillage treatments. K was the nutrient that presented the greatest losses (kg ha-1) at the end of the simulated rainfall because of the highest concentrations (mg L-1) added to high runoff coefficients of 45% for CT and 77% for NT. Thus, the evaluated system with cover crops and minimum soil tillage was not sufficient to control nutrient transfer in the soluble form during intense rainfall events.

title: Estimates of genetic parameters, genetic variability, and selection in the S1 generation of peach

description: ABSTRACT: The growing of peach in mild winter regions is made viable through the use of genotypes that have low need for cold conditions, and this is one of the main aims of breeding for these regions. Thus, the aims of this study were to estimate genetic parameters, evaluate genetic variability, and select families adapted to mild winter regions in the S1 generation of peach through mixed model methodology (REML/BLUP). For that purpose, 22 populations, 84 families, and 2090 individuals were evaluated for the following traits: bud burst rate (BR), node density (ND), plant height (PH), and trunk diameter (TD). Genetic variability was found for all the traits. Individual heritability in the broad sense was of low and medium magnitudes. The PH trait had positive genotypic correlation of high magnitude with TD. The ND trait had moderate negative genotypic correlation with PH and TD. Clustering by the Tocher method resulted in the formation of six mutually exclusive groups. Considering selection intensity of 25%, simultaneous selection for BR, ND, and TD led to predicted gains of 11.3% for BR, 9.7% for ND, -14.2% for PH, and -14.3% for TD, showing the great potential of the germplasm evaluated.

title: Activity of Piperaceae extracts and fractions in the control of Phytomonas serpens

description: ABSTRACT: Protozoa of the genus Phytomonas are harmful parasites to several agricultural crops of economic importance. Due to their recognized biological activity, crude extracts of Piper aduncum, P. crassinervium, P. hispidum, and P. amalago leaves, were tested using the microdilution plate technique to assess the antiparasitic potential against Phytomonas serpens. Results showed that the ethanolic crude extract of P. crassinervium and P. amalago presented the best inhibitory concentration for 50% of the cells (IC50), 16.5 µg mL-1 in chloroform phase, and 18 µg mL-1 in aqueous phase, respectively, after 48 h treatment. Cytotoxicity analyses were performed using the colorimetric method of sulforhodamine-B in LLCMK2 mammalian cells. The chloroform phase of P. crassinervium was subjected to the fractionation process, in which the ethyl acetate and dichloromethane fractions obtained better IC50 values. Scanning electron microscopy (SEM) images showed alterations in the cell membrane of the treated parasites. The data obtained indicate a potential antiparasitic effect of the Piper species analyzed against P. serpens, being considered promising candidates for formulations of bioproducts to control the parasite.

title: Milk quality in small farms from Southern Region of Brazil

description: ABSTRACT: This study aimed to evaluates some physical chemical aspects of chilled raw milk that meet Brazilian quality standards in smallholder farms from southern Region of Brazil. The fat content, crude protein (CP), total solids (TS), somatic cell count (SCC), and total plate count (TPC) of the chilled raw milk from 78 smallholder farms was analyzed between Oct 2014 and Feb 2017. It was found that 96% of the samples met the Brazilian regulations for fat content, 87% for CP, and 91% for TS. The mean values of TPC and SCC were higher than the maximum limits established by Brazilian regulations. Smallholder farms from Southern Region of Brazil produce milk with an adequate standard for the main chemical indicators. However, there is an important gap in compliance with hygienic-sanitary practices, leading to high levels of chilled raw milk that does not meet the limits of Brazilian regulations.

title: Genetic variability and linear relationships between plant architecture and maize grain yield

description: ABSTRACT: The objectives of this study were to analyze whether there is genetic variability and assess the linear relationships between plant architecture and maize grain yield. Three experiments were carried out in a complete randomized block design. A group of 51 cultivars was assessed in relation to 22 traits: number of leaves, plant height, ear height, leaf angle, leaf length, leaf width, leaf area, and grain yield. Individual analyses of variance were performed, the assumptions of normality of errors and homogeneity of residual variances were tested, and means were grouped by the Scott-Knott test. The phenotypic correlation matrix was constructed using the 22 traits of the 51 cultivars. Results showed that there is genetic variability among cultivars for number of leaves, plant height, ear height, leaf angle, leaf length, leaf width, leaf area, and grain yield. Leaves close to the ear have smaller leaf angle and larger length, width, and area of the leaves. Leaf angle gradually increases towards the lower and upper ends of the plant. Length, width, and area gradually decreases in leaves towards the lower and upper ends of the plant. Cultivars with higher number of leaves and larger leaf area are associated with higher grain yield.

title: Development and validation of a standard area diagram set to assess powdery mildew severity on watermelon leaves

description: ABSTRACT: The development and validation of a standard area diagram set (SADs) was proposed in this study to assess the severity of powdery mildew (Podosphaera xanthii) in watermelon (Citrullus lanatus) leaves. The SADs proposed has twelve levels of severity, varying from 0.07 to 100%. The SADs were validated by 16 raters who had no previous experience in evaluating plant disease severity. Initially, the estimation of severity was performed without the use of the SADs in leaves with different levels of severity. In a second moment, the same raters estimated the disease severity using the SADs proposed. By Lin’s concordance correlation analysis, there was an improvement in precision (coefficient of correlation, r = 0.878 and r = 0.959, without and with SADs, respectively) and accuracy (bias correction factor, Cb = 0.830 and 0.982, without and with SADs, respectively) using SADs when compared to the non-use of SADs. The agreement (Lin’s concordance correlation coefficient, ρc = 0.734 and 0.952 without and with SADs, respectively) also improved using SADs. Severity estimates inter-rater were more reliable when using SADs (coefficient of determination, R2 = 0.681 without and R2 = 0.864 with SADs; Intra-class correlation coefficient, ρ = 0.759 and ρ = 0.928, without and with SADs, respectively). Therefore, SADs improved precision, accuracy and reliability of powdery mildew severity on watermelon leaves.

title: Behavior of free omental grafts without vascular anastomosis implanted in cat’s experimental wounds

description: ABSTRACT: It is known that skin healing in cats is slower and has a higher complication rate than in dogs, what leads to search for new resources to enhance this process. Omentum properties in the aid of tissue repair are known and, among the forms of extraperitoneal omentalization, the use of free omental grafts without vascular anastomosis is advantageous, but little studied; there is no knowledge about its effect on skin healing, nor if it’s still viable when implanted in the subcutaneous space. Thus, the present study aimed to describe possible alterations produced by free omental graft without anastomosis inserted in the subcutaneous space, by means of macroscopic clinical analysis of the implantation region in cats. Twenty intact female cats were divided into two groups (Group 1: treated animals; Group 2: controls) of similar size. All animals were subjected to ovariosalpingohysterectomy (OSH) prior to the induction of an experimental wound for the implantation of the omental graft. Wounds were evaluated on days 1, 2, 4, 8, and 15 postsurgery and then weekly until no lesions were noted. Data regarding color, consistency, presence or absence of crusts, wound resistance, and volume measurements were recorded. There was activation of the omentum on the 4th day of evaluation with reduction of hemorrhage and an increase in the resistance to traction of the experimental wound. We concluded that the omentum without vascular anastomosis is capable of maintaining its viability and exert positive influence on the repair process without showing deleterious signs on the implantation site.

title: Adaptability of brazilian beans cultivars to industrial canning

description: ABSTRACT: A current alternative for meeting the modern consumer’s beans food demands is the industrial processing. This study evaluated the adaptability of eight Brazilian beans cultivars to industrial canning from commercial class cultivars of Carioca and of Black beans. The grains were processed in an industry sector using metallic cans with a capacity of 420 g, where the samples were conditioned without previous hydration. The cooking and sterilization process took place in a rotating autoclave. Quality parameters were evaluated in the canned beans. As a result, it was verified that, for the Carioca class, the Estilo cultivar differs from the rest of the genetic materials in terms of its low drained weight, which contributes to the increase in the total solids in the sauce, which have low hardness values. Estilo cultivar is not suitable for the type of processing used in this experiment. For the Black class, similar quality characteristics were observed between Esplendor and Uirapuru and between Esteio and Campeiro cultivars, where the latter stands out due to its lower damaged bean indices after processing. Finally, with the information present in this paper we intend to contribute to future researches on this subject and thereby increase the consumption and exportation of beans as processed product.

title: Persimmon anthracnose: a comparative study of aggressiveness on shoot and fruit among Colletotrichum horii isolates in southern Brazil

description: ABSTRACT: The persimmon tree is known for its rusticity and productivity and was first introduced to Brazil in the late 19th century. However, anthracnose disease is causing immature fruit drop and severe disease symptoms in persimmon fruit, shoots, flowers, and twigs. The causal agent was first described as the fungal species, Colletotrichum horii, which was first confirmed using only the ITS region. In this study, we compared the aggressiveness of 13 isolates of Colletotrichum spp. obtained from fruit and shoots of persimmon grown in the Metropolitan Region of Curitiba, Paraná State, Brazil. A multilocus molecular analysis was carried out based on ITS, GPDH, and EF genes, and we confirmed that the isolates were confirmed as C. horii. All isolates were pathogenic for unwounded and wounded persimmon fruit but differed in aggressiveness. Only one isolate was non-pathogenic when inoculated into unwounded persimmon shoots. Most isolates caused cankers and shoot death whether shoots were wounded or unwounded. In this study, we emphasized the importance of shoots as a source of primary inoculum. In future studies, it will be critical to further elucidate the epidemiological basis of anthracnose disease by conducting field studies to establish a more effective strategy for disease control.

title: Altrenogest treatment effects on the reproductive performance of sows during transition to batch farrowing

description: ABSTRACT: The synthetic progestin altrenogest (ALT) has been widely used in sow farms to concentrate artificial inseminations (AIs) during the transition of weekly productive flow for the batch farrowing system of 14 or 21 days. The objective of the present study was to investigate the effect of the duration of ALT treatment on the reproductive performance of weaned sows during transition to batch farrowing. Retrospective data was evaluated regarding the reproductive performance of primiparous and multiparous sows that were either not treated (control, n = 165) or treated with 20 mg ALT during 7 days (ALT7, n = 161) or 14 days (ALT14, n = 199) post-weaning. The interval between weaning or the end of ALT supplementation and first AI did not differ among the groups, as well as the percentage of sows inseminated up to 7 or 10 days after the end of treatment or weaning (P ≥ 0.16). There was a tendency for a lower farrowing rate (P = 0.06) in ALT7 (77.2%) when compared to ALT14 (84.5%) and control (86.3%) groups. The total number of piglets born did not differ among groups (P = 0.35). In conclusion, despite the slight delay in the estrus onset, the proportion of estrous sows was not affected, whereas the adjusted farrowing rate was reduced when ALT was administered for 7 days after weaning in multiparous sows during transition to 21 days batch farrowing system.

title: The effects of dietary hot pepper Capsicum annuum waste powder supplementation on egg production traits of Japanese quail layers

description: ABSTRACT: This study was conducted to evaluate the effects of different levels of dietary hot pepper (Capsicum annuum L.) waste supplementation on egg production performance and quality in Japanese quail hens (Coturnix coturnix japonica). A total of 192, seven-week-old Japanese quail layers were divided into 4 treatment groups of similar mean weight (304±0.5 g), each comprising 12 subgroups (including 1 male and 3 females). Treatment birds were fed on experimental basal layer diet supplemented with 1, 2 or 4 g hot pepper waste powder (HPWP) per kg diet. The laying performance was determined by recording feed intake, egg weight, daily egg production, and biweekly egg quality. Results showed that HPWP supplementation to layer diet did not have any significant (P&gt;0.05) effects on body weight and feed conversion ratio, while it had significant effects on feed intake (P&lt;0.01), and laying egg weight, average egg weight, total egg yield (P&lt;0.05). A 2 g HPWP supplementation resulted in the highest total egg yield (P&lt;0.05) with quadratic effects on egg shape index (P&lt;0.05) and albumen pH (P&lt;0.01). According to the values in the study, the egg shape index of 2 g HPWP group was circular and; therefore, attractive to consumers. We highly recommend the non-economic value of 2 g/kg supplementation of hot pepper waste powder, especially for egg production. To conclude, HPWP can be used for quail layer diets due to its beneficial effects on egg quality since it is an economic and easy agricultural by-product obtained from red pepper paste industry waste.

title: Acacia mearnsii tannin extract as a feed additive: impact on feed intake, digestibility and nitrogen excretion by sheep fed a tropical grass-based diet

description: ABSTRACT: The aim of this study was to evaluate the effect of the dietary inclusion of Acacia mearnsii tannin extract (TA) on nutrients intake and digestibility, and nitrogen (N) retention by sheep given a tropical grass-based diet. The trial was conducted with six castrated male sheep in a cross-over design in two 21-days experimental periods. The sheep were housed in metabolic cages and offered Tifton 85 hay (Cynodon dactylon) ad libitum plus concentrate at a rate of 12 g of dry matter (DM)/kg body weight (BW). The treatments were concentrate without (Control) or with 10 g TA/kg DM (Tannin). Concentration of TA in the diet was 3.8 g/kg DM and did not affect the feed intake or apparent digestibility. The TA decreased the true digestibility of n compounds (P&lt;0.05) whereas did not impact the N retention, microbial N flow to the small intestine or the efficiency of rumen microbial protein synthesis. In conclusion, a low dietary concentration of TA did not impact the nutrients supply and N use by sheep fed with a tropical grass-based diet.

title: Agricultural tractors conformity to the Brazilian traffic lighting and signaling legislation

description: ABSTRACT: Increasing the agricultural machinery visibility makes public roadways traffic safer by reducing the number of accidents and their severity. The study aimed to verify the compliance of new agricultural tractors with Brazilian law, given by, CONTRAN Resolution N° 454, NR12 and NR31, regarding the presence of lighting and signaling elements for traffic. The study was carried out in agricultural machinery dealers of seven brands, corresponding to 50 different models of new wheeled agricultural tractors. The items that was not present in total tractors sample are the rear position lamp, the reverse light and the rear retro-reflector. In addition, only one of the seven brands studied showed complete compliance with evaluated elements. Although, the Brazilian legislation specify the presence of lighting and signaling items for agricultural tractors traffic, there is not fully comply on tractors models analyzed and the Brazilian law are not homogeneously met by the agricultural tractor manufacturers in the verified sample, what can be leading to tractors traffic accident occurrences.

title: Impact of massage on goats on the human-animal relationship and parameters linked to physiological response

description: ABSTRACT: Considering the benefits that massage can promote, this research aimed to apply the stroking massage in five adult goats (G1-G5) assessed in group and individually for ten days. Parameters related to massage, immune system, physiology and behavior of goats were observed. There was only significant difference (P&lt;0.05) regarding behavior expressed in the presence of the masseur in G4 and G5, between week 1 and 2. Most goats accepted massage, except G2, with greater demonstrations of positive than negative behavior towards the masseur. Therefore, stroking massage promoted positive interactions between the masseur and goats, and should be explored as an alternative method to those existing in improving the relationship between humans and farm animals.
