ESTIMATION OF COMBINING ABILITY AND HETEROSIS FOR SOME MAIZE INBRED LINES AND ITS SINGLE CROSSES

Two field experiments were conducted out during 2012 and 2013 seasons to estimate combining ability, heterosis for six inbred lines (Three American inbreds: P97, B73and Oh.43 and three Egyptian inbred lines: R39, Inb.1021 and Inb.1004) and its F1 crosses. The most important results obtained from this investigation can be summarized as follows: The differences among means of parental inbreds and also among means of crosses were significant or highly significant for all studied traits. Mean squares of crosses were highly significant for all studied traits, indicating wide range of genetic variability among the studied crosses and this is primary requirement for further computation. Both general and specific combining abilities mean squares were found to be highly significant for all studied traits. GCA/SCA variances ratios were found to be lower than unity for six traits i.e. time to tassel emergency, time to silk emergency, number of rows/ear, number of kernels/row, grain yield/plant and shelling percentage and higher than unity for plant height and 100-Kernel weigh. Significant positive general combining ability (GCA) effects were found for most studied traits. The best combiners were P2 (P79) and P4 (Inb.1021) for earliness traits; P5 (Inb.1004) and P6 (Oh.43) for plant height; P5 (Inb.1004) for number of rows/ear; P1 (R39) for number of grains/row; P2 (P97), P3 (B73) and P4 (Inb.1021) for 100-grain weight; P1 (R39) for grain yield/plant; P1 (R39) and P2 (P97) for shelling percentage. Significant positive specific combining ability (SCA) effects were found for most studied traits. The best cross combinations P3×P4 for number of rows/ear; P1×P5 for number of grains/row; P1×P3, P1×P6, P2×P3, P2×P5, P3×P5 and P4×P6 for 100-Grain weight; P1×P2, P1×P5, P2×P5, P3×P6 and P4×P5 for grain yield/plant; P1×P5, P3×P6 and P4×P5 for shelling percentage. Results showed significant or highly significant heterosis over mid-parents and better parents for all studied traits. The best crosses over mid and better parents were (P1×P5) for number of rows/ear; (P1×P6) for number of grains/row; (P2×P5) for100-grain weight;(P1×P6)for grain yield and (P1×P4) for shelling percentage. The study recommends using inbred line P3 (B73) and crosses P1×P2, P1×P3 and P3×P6 in breeding program of maize to improve the yield and its components where they recorded the highest value of the grain yield/plant and gave a better combining ability.

response of coffee senna sennaoccidentalis seeds to different fermentation periods

A laboratory analysis was conducted to investigate the effect of varying fermentation period on the proximate composition, amino acid profile and levels of anti-nutritional factors of Sennaoccidentalis seeds.The seeds were fermented for 0,3,5,7 and 9 days, respectively in replicate of three in a completely randomized design. The proximate composition, amino acid profile and level of anti-nutritional factors of the Sennaoccidentalis seeds subjected to different fermentation periods were determined using standard laboratory procedure. Data obtained were subjected to analysis of variance of the completely randomized design (CRD) using Statistics 9.0. The results indicated that the proximate composition of Sennaoccidentalis seeds significantly (P<0.05) increases as the fermentation period progresses except for the ether extract and nitrogen-free extract which reduced as the fermentation period increased. The amino acid content similarly showed significant (P<0.05) increase as the fermentation period advanced. The level of the anti-nutritional factors were observed to significantly (P<0.05) decline as the fermentation period progresses. It can be concluded that Sennaoccidentalis seeds can be fermented up to 9 days without adverse effect on the nutritive value of the seeds. However, fermentation for 5 is recommended due to its minimal reduction of ether extract and nitrogen-free extract when compared to 7 and 9 days fermentation. The fermented seed meals should be used in a feeding trial in order to evaluate their feeding value to animals.
Decline in the strength of genetic controls on aspen environmental responses from seasonal to century‐long phenomena

Understanding intra-speci ﬁ c variation in climate sensitivity could improve the prediction of tree responses to climate change. We attempted to identify the degree of genetic control of tree phenology and growth of trembling aspen ( Populus tremuloides Mchx.) in a natural stand of this species in northwestern Quebec. We mapped and genotyped 556 aspen trees growing within the plot, using seven nuclear microsatellite loci for clone identi ﬁ cation. We selected 13 clones ( n of trees per clone > 5, in total 350 trees) and evaluated the explanatory power of clone identity in (a) variability of spring leaf phenology and (b) short- and long-term growth responses. The clone ’ s identity explained 43% of the variability in spring leaf phenology, between 18% and 20% of variability in response to monthly climate variables signi ﬁ cantly affecting growth, between 8% and 26% of growth response to insect outbreaks, and 12% in the long-term growth rates. Strong clonal control of aspen phenology and moderate control of growth responses to monthly weather do not result in an equally large impact on long-term growth rates. The result suggests an important role of environmental extremes and within community interactions as factors averaging aspen growth performance at the stand level.
FieldLight: Device-Free Indoor Human Localization Using Passive Visible Light Positioning and Artificial Potential Fields

Device-free or passive localization techniques allow positioning of targets, without requiring them to carry any form of transceiver or tag. In this paper, a novel device-free visible light positioning technique is proposed. It exploits the variation of the ambient light levels caused by a moving entity. The target is localized by employing a system of artificial potential fields associated with a set of photodiodes embedded into an indoor environment. The system does not require the existing lighting infrastructure to be modified. It also employs a novel calibration procedure that does not require labelled training data, thus significantly reducing the calibration cost. The developed prototype system is installed in three typical indoor environments consisting of a corridor, foyer, and laboratory and was able to attain median errors of 0.68m, 1.20m and 0.84m respectively. Through experimental results, the proposed VLP technique is benchmarked against an existing wireless RSSI-based device-free localization approach, and was able to attain a median error 0.63m lower than the wireless technique.
Superovulatory Response of Egyptian Buffaloes Treated with A Single Dose of Pmsg as Affected by Diameter of The Dominant Follicle

The present work was conducted to evaluate the efficacy of two superovulatory regimens to determine the diameter of follicle using ultasonography to monitoring the ovarian activity for superovulation in 21 buffalo cows, giving PMSG and PGF2α. Superovulation regime was done by injection PMSG (3000 IU) when follicular diameter of the dominant follicles reach 5-7 mm (G1, n=7), >7-9 mm (G2, n=7,) and >9 mm (G3, n=7). Buffaloes in all groups were injected with 2 ml PGF2α and naturally inseminated depend on detection of estrous within 48-72 h of PGF2 injection. Flushing was conducted 7 days after insemination to determine the ovulatory response. Ultrasonography device was used during treatment period to record the number of follicles and CL and diameter of the follicles for PMSG injection. Results showed that the duration from Day 0 (estrus) up to PMSG injection was earlier (P<0.05) in G1 than in G2 and G3 (day 7.04 vs. days 9.2 and 9.8, respectively), but did not differ significantly in G2 and G3. The observed insignificant early time of treatment in G3 than in G2 was associated with wider range of treatment time in G3 than in G2 (day 8-10 vs. day 8-12). All buffalo cows in all groups came in estrus showing an estrus rate of 100% in each group. All buffaloes in G2 (100%) produced CL vs. 71.4 and 85.7% of buffaloes in G1 and G3, respectively. No embryos were produced from animals in G1, although 71.4% of animals in this group produced ovulation sites. Response rate of embryo production doubled in G2 as compared to G3 (57.1 vs. 28.6%). Buffalo cows in G2 showed insignificantly the highest total ovulatory response as compared to G1 and G3 (2.71 vs. 2.14 and 2.29, respectively). Number of unovulated follicles was insignificantly lower, while number of CLs per animal (total or responded animals) was higher (P<0.05) in G2 than in G1 and G3.Animals in G2 showed the highest (P<0.05) average number of CLs per responded animal, while number of embryos per responded animals or animals produced embryos was insignificantly the highest in G2 as compared to other groups. Buffalo cows in G2 produced embryos at morula (2 embryos/group) and blastocyst (2 embryos/group) stages, while those in G3 yielded embryos only at compact morula (2 embryos /group) stage. In comparing embryo production of G2 and G3, results revealed that averages number of total and transferable embryos were greater in G2 by about 50% than in G3. These findings are associated with higher recovery rate of total embryos in G2 than in G3, respectively. The obtained results indicated that the potentiality of PMSG injection to induce high superovulatory response in buffaloes is highly related to follicular diameter. Under the experimental conditions of the present study, appropriate time for superovulation in buffalo cows treated with 3000 IU of PMSG was when diameter of the dominant follicle reached a rang between ≤7 and 9 mm to reflect the highest ovulatory response.
Tximeta: Reference sequence checksums for provenance identification in RNA-seq

Correct annotation metadata is critical for reproducible and accurate RNA-seq analysis. When files are shared publicly or among collaborators with incorrect or missing annotation metadata, it becomes difficult or impossible to reproduce bioinformatic analyses from raw data. It also makes it more difficult to locate the transcriptomic features, such as transcripts or genes, in their proper genomic context, which is necessary for overlapping expression data with other datasets. We provide a solution in the form of an R/Bioconductor package tximeta that performs numerous annotation and metadata gathering tasks automatically on behalf of users during the import of transcript quantification files. The correct reference transcriptome is identified via a hashed checksum stored in the quantification output, and key transcript databases are downloaded and cached locally. The computational paradigm of automatically adding annotation metadata based on reference sequence checksums can greatly facilitate genomic workflows, by helping to reduce overhead during bioinformatic analyses, preventing costly bioinformatic mistakes, and promoting computational reproducibility. The tximeta package is available at https://bioconductor.org/packages/tximeta.
Estimates of soil losses by the erosion potential method in tropical latosols

ABSTRACT Water erosion is one of the main problems faced in coffee cultivation, as it promotes environmental degradation and crop yield decrease. Erosion estimates support the planning of conservation management practices and allowing determining the rates of soil losses. Thus, the objective of this paper was to estimate the soil loss by water erosion using the Erosion Potential Method in a sub-basin predominantly covered by coffee cultivation and then to compare the results with the Soil Loss Tolerance limits. The study area is the Coroado Stream Sub-basin, located at Alfenas Municipality, south of Minas Gerais, Brazil. The sub-basin presented an Erosion Coefficient of 0.272, indicating a predominance of low-intensity erosion. The total soil loss estimate was 1,772.01 Mg year-1 with an estimated average of 1.74 Mg ha-1 year-1. Soil Loss Tolerance limits range from 4.75 to 7.26 Mg ha-1 year-1 and, according to the Erosion Potential Method, only 1.0% of the sub-basin presented losses above the limits. The areas with the highest slopes and bare soil concentrated the highest losses rates and should be prioritized in the adoption of mitigation measures. The Erosion Potential Method estimated soil losses in tropical edaphoclimatic conditions in a fast, efficiently and at low cost, supporting the adoption of conservation management practices.
World Heritage meets Smart City in an Urban-Educational Hackathon in Rauma

During recent years, the ‘smart city’ concept has emerged in literature (e.g., Kunttu, 2019; Markkula & Kune, 2018; Öberg, Graham, & Hennelly, 2017; Visvizi & Lytras, 2018). Inherently, the smart city concept includes urban innovation; therefore, simply developing and applying technology is not enough for success. For cities to be 'smart,' they also have to be innovative, apply new ways of thinking among businesses, citizens, and academia, as well as integrate diverse actors, especially universities, in their innovation practices (Kunttu, 2019; Markkula & Kune, 2018).
Towards Building Creative Collaborative Learning Groups Using Reinforcement Learning

Increasing creative skills in collaborative groups is of huge interest for stakeholders in education, industry, policy making etc. However, construction of “the most” creative groups given a cohort of people and a set of common goals and tasks to perform is challenging. The complexity of this undertaking is amplified by the necessity to first understand and then measure what “the most” creative means in a particular situation. We present here our method of semi-automatic building of “the most” creative learning groups given a cohort of students and a particular learning context based on reinforcement learning (an adapted Q-learning algorithm). Various attributes that influence individual and group creativity may be considered. A case study on using this method with our Computer Science students is also included. However, the method is general and can be used for building collaborative groups in any situation, with the appropriate “the most” creative goal and attributes.
When knowledge management matters: interplay between green human resources and eco-efficiency in the financial service industry

Purpose Drawing on the ability–motivation–opportunity theory applied to the greening of service industries, this paper aims to analyze the extent to which green human resource management plays a role in the adoption of eco-efficiency principles in the financial sector. Environmental knowledge management represents one of the key green human resource management components. Design/methodology/approach This study conducted a survey with 178 employees working within one of the largest financial banks in Brazil, which has been investing in eco-efficiency for more than ten years. Findings On the basis of structural equation modelling, this study has provided the following findings: Among all factors taken into consideration in this study, only environmental training positively influences eco-efficiency; training may be suffering owing to barriers associated with empowerment and teamwork; the eco-efficiency program of the studied company would get benefits if it provided more autonomy to employees; and finally, the eco-efficiency program of the studied bank could be more effective if connected with green teams. Originality/value To date, this is the first work that relates – with empirical evidence from Brazil – GHRM and eco-efficiency in the financial service industry.
Monodelphis domestica as a Fetal Intra-Cerebral Inoculation Model for Zika Virus Pathogenesis

Monodelphis domestica, also known as the laboratory opossum, is a marsupial native to South America. At birth, these animals are developmentally equivalent to human embryos at approximately 5 weeks of gestation which, when coupled with other characteristics including the size of the animals, the development of a robust immune system during juvenile development, and the relative ease of experimental manipulation, have made M. domestica a valuable model in many areas of biomedical research. However, their suitability as models for infectious diseases, especially diseases caused by viruses such as Zika virus (ZIKV), is currently unknown. Here, we describe the replicative effects of ZIKV using a fetal intra-cerebral model of inoculation. Using immunohistochemistry and in situ hybridization, we found that opossum embryos and fetuses are susceptible to infection by ZIKV administered intra-cerebrally, that the infection persists long term, and that the infection and viral replication consistently results in neural pathology and may occasionally result in global growth restriction. These results demonstrate the utility of M. domestica as a new animal model for investigating ZIKV infection in vivo. This new model will facilitate further inquiry into viral pathogenesis, particularly for those viruses that are neurotropic, that may require a host with the ability to support sustained viral infection, and/or that may require intra-cerebral inoculations of large numbers of embryos or fetuses. AUTHOR SUMMARY Here we show that the laboratory opossum (Monodelphis domestica) is a valuable new model for studying Zika virus pathogenesis. Newborns are at the developmental stage of 5-week human embryos. Zika virus inoculated on a single occasion into the brains of pups at the human developmental stages of 8-20 weeks post conception replicated in neuronal cells and persisted as a chronic infection until the experimental endpoint at 74-days post infection. In addition, we observed global growth restriction in one of 16 inoculated animals; global growth restriction has been observed in humans and other animal models infected with Zika virus. The results illustrate great potential for this new animal model for high throughput research on the neurological effects of Zika virus infection of embryos and fetuses.
Short-wavelength instability of a vortex in a multipolar strain field

The extension of the elliptical instability to a rotational flow with an n-fold symmetry is considered in this Brief Communication. Based on the geometrical optics approach, the short-wavelength stability analysis of the multipolar strained vortex described by the streamfunction (in polar coordinates) Ψn=r2/2−(p/n)rn cos(nθ) is carried out for n=3,4,5 and p⩾0. Both the growth rate and the wavevector properties of the most unstable wave are computed as a function of the real parameter en=p(2nC/(n−2))(n−2)/2 which characterizes the geometry of the streamline Ψn=C. For almost circular flows, i.e., in the small en limit, exact estimates are also obtained by perturbation methods.
The complete chloroplast genome of an economic plant, Chrysanthemum morifolium ‘Baekma’

Abstract Chrysanthemum morifolium (Dendranthema grandiflorum), known as florist’s daisy is an important ornamental and medicinal plant of the Asteraceae family. The complete chloroplast genome sequence of one economic cultivar ‘Baekma’ was 151,060 bp in length with a large single copy (LSC) region (82,862 bp), a small single copy (SSC) region (18,294 bp) and two inverted repeats (IRs) (24,952 bp). It contained 130 genes, including 85 protein-coding genes, 8 rRNAs and 37 tRNAs. The overall GC content was 37%. Phylogenetic analysis showed that C. morifolium ‘Baekma’ was grouped together with other Chrysanthemum species.
Employing Spatial Sonification of Target Motion in Tracking Exercises

This paper presents the results of an experiment in which the effect of spatial soniﬁcation of a moving target on the user’s performance during the execution of basic tracking exercises was investigated. Our starting hypothesis is that a properly designed multimodal continuous feedback could be used to represent temporal and spatial information that can in turn improve performance and motor learning of simple target following tasks. Sixteen subjects were asked to track the horizontal movement of a circular visual target by controlling an input device with their hand. Two different continuous task-related auditory feedback modalities were considered, both simulating the sound of a rolling ball, the only difference between them being the presence or absence of binaural spatialization of the target’s position. Results demonstrate how spatial auditory feedback signiﬁcantly decreases the average tracking error with respect to visual feedback alone, contrarily to monophonic feedback. It was thus found how spatial information provided through sound in addition to visual feedback helps subjects improving their performance.
Impact of light quality on the physiological characteristics of Capsicum chinense seeds

The objective of this work was to evaluate the physiological quality of Capsicum chinense seeds submitted to different light spectral qualities. It was used a completely randomized design, in a 4x5 factorial scheme, with four pepper cultivars [BRS moema biquinho yellow (Biq. Yellow), Airetama biquinho red (Biq. Red), Boyra Habanero red (Boyra Hab. Red), BRS Seriema tupa bode red (Tupa Bode Red)] and five light spectral qualities, being blue LEDs (B-LEDs); red LEDs (R-LEDs); blue+red LEDs (BR-LEDs); white LEDs (W-LEDs) and fluorescent lamp (FL) carried out germination and vigor analysis, with four replicates of 50 seeds. For this, the seeds were conditioned inside gerbox® boxes and kept in a growth room. The Biq. Yellow and Boyra Hab. Red peppers showed the highest potential of germination and vigor, respectively, indicating high physiological quality. In general, the light spectral qualities provide differentiated responses in the initial development of the pepper cultivars, being the reduction of the percentage of dead seeds favored by the spectrum BR-LEDs and W-LEDs. The root fresh mass is increased by all lights, except R-LEDs. The fresh mass of the aerial part presents positive results in the FL lamps. Shoot length is favored by the R-LEDs.
Lethal and inhibitory activities of natural products and biopesticide formulations against Tetranychus urticae Koch (Acarina: Tetranychidae)

ABSTRACT Natural products namely; cow urine, Darekastra, fermented buttermilk, Jeevamrit, Panchgavya, Tamarlassi, vermiwash, and biopesticide formulations; Eupatorium 5EC, Melia 5EC and Neem baan 0.15EC were evaluated for toxic, ovicidal activity, repellence, feeding, and oviposition deterrence using leaf dip method of bioassay against Tetranychus urticae Koch. The LC50 for natural products ranged from 1.09% to 15.15%, minimum and maximum corresponding to fermented buttermilk and Panchgavya, respectively, whereas it ranged from 0.00007% to 0.03% for biopesticide formulations, maximum for Melia 5EC and minimum for Neem baan 0.15EC. At recommended field dose, toxicity varied from 18.5% to 90.0% and the ovicidal activity ranged from 5.61% to 54.48%, maximum being for Neem baan 0.15EC. All natural products exhibited moderate level of repellence and oviposition deterrence but Neem baan 0.15EC was ranked highest for both the properties. Feeding deterrence was at low levels for the natural products while Neem baan 0.15EC exhibited 100% of feeding deterrence. An exception was observed for leaf treatment with Panchgavya which acted as an oviposition inducer for the red spider mites. Based on arbitrary rank score, fermented buttermilk, Tamarlassi, and Neem baan 0.15EC possessed high toxic properties to spider mites.
