description: The increasing use of computational methods for the analysis of biological data and the constant expansion verified in the fields of Bioinformatics and Computational Biology have revolutionized the study of Biology during the past few decades. However, grasping the complex nature of some softwares employed for such analyses and adapting to the rapid changes observed in computational ecosystems has become a major challenge for biologists, hampering the full use of such resources by the scientific community. This problem becomes more serious due to the fact that many computational methods often rely on pipelines composed by multiple analytical steps, involving different scripts, softwares and/or algorithms with unique requirements and/or dependencies. As a result, utilization of computational resources during bioinformatics analyses has become increasingly heterogeneous across laboratories, compromising reproducibility and replicability of results obtained from a given experiment or dataset. Although the Bioinformatics community has heavily relied on the production of Open Source softwares as a way to minimize these problems, mandatory installation of libraries for the proper functioning of scripts, lack of proper documentation and incompatibility with different operating systems and/or hardware still represent major obstacles to ensure replicability and reproducibility of data analysis in different computational environments. Fortunately, emergence of the Docker project is providing a promising new strategy to tackle these problems, by allowing the configuration of a complete computing environment, in which all libraries, codes and additional data required for a particular application may be implemented in a single container, which can be consistently exchanged and launched in different platforms, regardless the specificities of their hardware and/or operating systems. Thus, to explore and demonstrate the usefulness of Docker-based systems as a strategy to enhance replicabability and reproducibility of bioinformatics analyses in multiple computing environments, we developed the application Dugong, a Docker image based on Ubuntu 15.10, specifically designed for the analysis of large-scale biological data. Using a graphic interface generated by Xfce4, Dugong provides the managers Linuxbrew (Homebrew Science) and Conda (Bioconda), which allow distribution and installation of over 3000 bioinformatics-related packages and libraries, with automated installation of their respective dependencies. Simulations performed in virtual machines demonstrate that Dugong allows effective creation of reusable containers for different bioinformatics analyses in a uniform computational environment, allowing acquisition of consistent and reproducible results by the scientific community, thus assisting in the development of Open Science projects.

description: Infrared and visible cameras were mounted on an unmanned aerial vehicle (UAV) to image bridge deck surfaces and map likely concrete delaminations. The infrared sensor was first tested on laboratory validation experiments, to assess how well it could detect and map delaminations under controlled conditions. Field tests on two bridge deck surfaces further extend the validation dataset to real-world conditions for heterogeneous concrete surfaces. Performance of the mapping instrument and algorithms were evaluated through receiver operating characteristic (ROC) curves, giving acceptable results. To improve the performance of the mapping by reducing the rate of false positives, i.e., areas wrongly mapped as being affected by delamination, visible images were jointly analyzed with the infrared imagery. The potential for expanding the method to include other products derived from the visible camera data, including high density 3D point locations generated by photogrammetric methods, promises to further improve the performance of the method, potentially making it a viable and more effective option compared to other platforms and systems for imaging bridge decks for mapping delaminations.

Year: 2020
Subjects: Conventional Roundabout, Turbo Roundabout, Operation, Capacity, Safety

description: Addis Ababa is experiencing rapid growth in the business and construction activities
 which in turn increase the number of vehicles with an alarming rate. For this reason,
 currently there is an attempt to develop infrastructures like road networks improvement and
 evaluation and improving intersection control mechanism in the city. But still there is a
 huge gap in developing road segment and intersection with good operational and safety
 performance. The introduction of the turbo roundabout in Addis Ababa can have a
 massive impact on the road safety and capacity problem in the city.
 In this study the roundabout at Africa Union intersection was modeled using VISSM
 software and proposed and designed Turbo roundabout using Torus software as an
 alternative solution in terms of operational and safety performance.
 Traffic volume is a major input, motorized Traffic data was collected in morning and
 night time peak hour for 2 consecutive days from 8:00am to 9:00 am in the morning
 and from 5:30pm to 6:30pm for night peak hour. The hourly traffic volume distribution
 revealed that the peak hour traffic between 8:00am to 9:00 am in the morning.
 Pedestrian volume count was used from secondary data of previous study on each
 approach that cross the road on both directions in-bound and out-bound to the approach.
 Then both existing and proposed intersection operational performance analysis is
 conducted using VISSIM software.
 The results showed 85sec delay and 80m queue lengths with F LOS. As an alternative
 solution reconstruction of the intersections has been made into Rotor turbo roundabouts
 and results revealed the intersection better performance with 32 sec delay, 34m queue
 length with D LOS. Finally, the performances for two types of roundabouts are
 determined with the using VISSIM software.
 The analysis has proven that with the input parameters, rotor turbo roundabout offers
 better performances and safety improvement compared to the existing intersections as
 it can be taken as an alternative solution.

description: According to the new Ethiopia construction information and Geological survey, the
 ground acceleration of the country is increasing and almost many of the bridge in
 Ethiopia designed based on the implementation of the new design code. Analytical
 enquiry was conducted to investigate the effect of Carbon Fiber Reinforced Polymer
 (CFRP) for retrofitting the bridge column in plastic hinge region for non-seismically
 detailed circular column. Finite Element method was used to investigate the selected
 bridge column performance and also to evaluate the retrofitting capacity carbon Fiber
 reinforced polymer, the results obtained were validated using Farid’s and Priestley’s
 empirical formulas. The performance of the selected bridge column under the old and the
 new seismic design code was comparatively investigated. Furthermore, the efficiency of
 CFRP jacketing in plastic hinge region for retrofitting the bridge column for added
 seismic load was evaluated. For the selected bridge column, earthquake load was
 estimated using new design code has 33 % load and40% total deformation increment than
 the estimated value of load using old design code and the effect of the two loads
 analyzed. Overall retrofitting the selected bridge column with Carbon Fiber Reinforced
 polymer with increasing thickness from 3mm to 4mm and wrapping the columns from
 layer one to three reduce the ultimate deformation, the ultimate rotation and Curvature of
 the bridge column 5% to 21%.

description: The paper develops a systematic estimation and inference procedure for quantile regression models where there may exist a common threshold effect across different quantile indices. We first propose a sup-Wald test for the existence of a threshold effect, and then study the asymptotic properties of the estimators in a threshold quantile regression model under the shrinking threshold effect framework. We consider several tests for the presence of a common threshold value across different quantile indices and obtain their limiting distributions. We apply our methodology to study the pricing strategy for reputation through the use of a data set from Taobao.com. In our economic model, an online seller maximizes the sum of the profit from current sales and the possible future gain from a targeted higher reputation level. We show that the model can predict a jump in optimal pricing behavior, which is considered as “reputation effect” in this paper. The use of threshold quantile regression model allows us to identify and explore the reputation effect and its heterogeneity in data. We find both reputation effects and common thresholds for a range of quantile indices in seller’s pricing strategy in our application.

description: This study aims to find the optimal medium and conditions for polylactic acid (PLA)-degrading enzyme production by Amycolatopsis sp. SCM_MK2-4. Screening of the most effective components in the enzyme production medium by Plackett–Burman design revealed that the silk cocoon and PLA film were the most significant variables enhancing the PLA-degrading enzyme production. After an response surface methodology, a maximum amount of PLA-degrading enzyme activity at 0.74 U mL−1 was predicted and successfully validated at 95% after 0.39% (w/v) silk cocoon and 1.62% (w/v) PLA film were applied to the basal medium. The optimal initial pH value, temperature, and inoculum size were evaluated by a method considering one-factor-at-a-time. The values were recorded at an initial pH in the range of 7.5–9.0, a temperature of 30–32°C, and an inoculum size of 4–10%. The highest activity of approximately 0.95 U mL−1 was achieved after 4 days of cultivation using the optimized medium and under optimized conditions in a shake flask. Upscaling to the use of a 3-L stirred tank fermenter was found to be successful with a PLA-degrading activity of 5.53 U mL−1; which represents a 51-fold increase in the activity compared with that obtained from the nonoptimized medium and conditions in the shake flask.

description: Pierce's disease (PD) is a highly destructive disease, responsible for great losses in the North American viticulture industry. It is caused by the xylem-limited bacterium Xylella fastidiosa and characterized by blockage of xylem vessels by bacterial aggregates, which leads to water stress and chlorosis of leaf tissue, among other symptoms, affecting fruit development and overall plant productivity. However, the exact mechanisms that lead to PD development in vineyards are still poorly understood, which prompted us to employ RNA-seq analysis, in an attempt to perform a global-scale evaluation of the main metabolic alterations that occur in PD-affected plants. Thus, we inoculated four 3-month-old Vitis vinifera plants (Thompson Seedless variety) with Xylella fastidiosa (Temecula strain), which were next incubated in a greenhouse for four months. At this point, PD symptoms were clearly visible and RNA from affected leaves was extracted (Fig. 1). RNA was also extracted from theleaves of four healthy, uninfected plants that were incubated under the same conditions, to serve as control. These RNA samples were then sequenced in an Illumina platform and transcripts were mapped against the entire Vitis vinifera reference genome, with the aid of Tophat (Tab. 1). After mapping, the relative abundance of transcripts was calculated with Cufflinks and the differentially expressed genes were identified with Cuffdiff (Fig. 2). A total of 5,779 differentially expressed transcripts were obtained after this analysis, identifying several pathways that seem to be affected in diseased plants, such as photosynthesis, wax production and synthesis of chalcones, among others (Fig. 3).

description: The interior office building thermal comfort is very important for occupant performance. Office
 building is built to shade occupants from harsh outdoor weather condition. However, the
 phenomena of temperature rise or overheating probably question the performance of the building
 in terms of thermal comfort. This study investigates the thermal comfort performance of the
 naturally ventilated buildings of some selected Addis Abba sub-city administration offices in
 different orientations. And the study assessed the effectiveness of building code regulation on
 thermal comfort bilaterally. This study is based on building users survey, field measurements,
 and secondary data review and analysis. The field study and survey were carried in the warmest
 month of the city May 2019 for a selected room of the case buildings. The field study and survey
 assessed the indoor air temperatures and relative humidity levels of selected five office building
 rooms, as the occupants completed questionnaires covering their thermal sensations and thermal
 preferences. Moreover, a literature review is carried out to discuss the possible passive design
 strategies and regulations used to improve the thermal performance and environmental design
 guidelines of the office buildings based on the occupants thermal requirements. The data
 obtained from the survey was analysed by SPSS and excel software and secondary data was
 analysed in a practical part through measurement from survey data collection. Results of field
 studies have shown that most of the occupants prefer a cooler environment and found their
 thermal environment not comfortable. The indoor temperature fluctuation of the buildings and
 the humidity level are within the allowable limits. But, sometimes the temperature levels
 overpass the acceptable range. The result also revealed that there is a difference in thermal
 performance between the buildings in different orientations. At the time of measurements Gulale
 sub-city administration office building oriented towards North West perform better to occupants
 thermal environment compared to other buildings. Consequently, to improve the internal
 environment, additional appropriate passive design strategies are recommended. And the
 building regulation of the city as well as the country is recommended to incorporate about
 thermal comfort.

description: This paper assesses the performance of common estimators adjusting for differences in covariates, such as matching and regression, when faced with the so-called common support problems. It also shows how different procedures suggested in the literature affect the properties of such estimators. Based on an empirical Monte Carlo simulation design, a lack of common support is found to increase the root-mean-squared error of all investigated parametric and semiparametric estimators. Dropping observations that are off support usually improves their performance, although the magnitude of the improvement depends on the particular method used.

description: In addition to the economic advantages, using fly ash in cement has enormous effect on the
 mechanical properties of the concrete. Moreover, Researchers have identified that the addition of
 fibers to concrete increases its mechanical properties. Therefore, Better concrete product using
 both fly ash and fibers especially natural fibers which are more economical and eco-friendlier
 than the other fibers for an improved concrete strength production is the major aim of this
 research. This experimental investigation had been undertaken to study a fly ash concrete
 reinforced with bamboo fibers. The optimum percentage of fly ash to replace cement was first
 determined by compressive strength test for different percentages by weight of fly ash
 substitution. After that, mechanical properties of the fly ash concrete were studied with the
 addition of three different percentages of bamboo fibers. Mix designs were formulated for all
 percentage and then, Specimens were casted and tested for computing compressive strengths,
 indirect tensile strengths and flexural strengths for 7th and 28th day period. In the experiments,
 non-fibrous 25% fly ash substituted with cement concrete (the optimum percentage which was
 first determined using compressive strength) were compared with the 25% flyash substituted
 with cement for the individual fibers percentages. The standard 150mm cube compressive
 strength of bamboo fiber reinforced Fly Ash Concrete with 0.10% addition of bamboo fiber by
 weight of concrete showed an increment of 12.44%, Whereas bamboo fiber reinforced Fly Ash
 Concrete with 0.2% and 0.30% addition of bamboo fiber by weight of concrete showed a
 compressive strength reduction of 9.33% and 33.03% respectively compared to non-fibrous fly
 ash concrete. Bamboo fiber reinforced Fly Ash Concrete with 0.10% and 0.20% bamboo fiber
 addition by weight of concrete showed an increment in mean split tensile strength of 5.81% and
 0.12% respectively; whereas 0.30% additions of bamboo fiber by weight of concrete showed
 split tensile strength reduction of 14.54% compared to non-fibrous fly ash concrete. Mean
 Flexural strength of bamboo fiber reinforced Fly Ash Concrete with 0.10%, 0.20% and 0.30%
 addition of bamboo fiber by weight of concrete showed an increment by 2.48%, 5.98% and
 7.80% compared to non-fibrous fly ash concrete respectively.

The Impact of Lowest Bidder Bid Awarding system on Project performance : Case Study on Ethipian Federal Road Projects
Creators: name: Melaku, Abraham
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020
Subjects: Project performance, Procurement system, Least bidder, Road construction projects.

description: Construction project performance is highly influenced by the type of construction procurement
 method used to deliver the projects, Ethiopian construction industry participants have long
 recognized that accepting the lowest price bid which does not guarantee value for money.
 Achieving a value-based procurement approach is a challenge, particularly for the Ethiopian
 public road construction sector. In the current situation, it is increasingly likely that
 construction organizations will submit abnormally least bidders to win new projects. Persisting
 problems of inferior quality of constructed facilities, frequent cost and time overruns, high
 incidence of claims and litigation have become the main features in Ethiopian public road
 construction projects. This study aimed to analyze the impact of lowest bidder bid awarding
 selection and awarding system on project performance. This study was carried out based on a
 literature review, document analysis and case study projects were taken to collect data on the
 desired points. A total of 37 completed and 18 under progress projects were collected from
 construction Ethiopian road authority (ERA) using random and snow ball sampling method.
 The results and discussion concentrate on the effect of the least bidder bid awarding
 procurement system on road construction projects performance. It is found that the
 procurement process and system by itself in use are much of traditional methods specifically
 the lowest qualified bidder which has direct contribution to projects cost overrun and delay
 which lead to poor performance of projects towards attaining the intended target from the study
 part of multiple regression summary result, there was a significant positive relationship
 between project final cost and all three dependent variables this show there is unrealistic
 estimation of project cost; as indicated by regression coefficient of 0.78, also from the research
 linear regression result initial cost accounted for a significant percentage, 71.6%, of the change
 in cost performance of project holding all other factors constant. The study conclude that this
 lowest bidder bid awarding procurement system procedure may guarantee the lowest cost of
 project but not the best value for money

description: This paper assesses the performance of common estimators adjusting for differences in covariates, such as matching and regression, when faced with so-called common support problems. It also shows how different procedures suggested in the literature affect the properties of such estimators. Based on an Empirical Monte Carlo simulation design, a lack of common support is found to increase the root mean squared error (RMSE) of all investigated parametric and semiparametric estimators. Dropping observations that are off support usually improves their performance, although the magnitude of the improvement depends on the particular method used.
Soviet nuclear munitions in Czechoslovakia: 1965-1991
Creators: name: Polnar, Stanislav
Publisher: name: British Journal for Military History
Year: 2024

description: Under a Czechoslovak-Soviet treaty signed in 1965, the rapidly developing missile forces and air force of the Czechoslovak People’s Army (Czech acronym and hereinafter ‘ČSLA’) were to be strengthened with the addition of nuclear munitions. These were to be used to support planned operations on the so-called Czechoslovak Front. Operation JAVOR consisted of the construction of three nuclear depots, which were manned by special units of the Soviet Army. A new agreement between the CSSR and the USSR was entered into in 1986, extending the existing conditions of storage. Fundamental changes were brought about in 1989 by the Velvet Revolution and the end of the Cold War.

The Impact of Compensation on workforce Productivity: A Case study on Ethiopian shipping & Logistics Services Enterprise
Creators: name: Tewodros Andualem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020
Subjects: Employee, Compensation, workforce Productivity

description: The main objective of the study is to assess the impact of compensation on the
 productivity of the workforce at Ethiopian Shipping and Logistic Service Enterprise
 (ESLSE) as a case. The research design is descriptive in its nature and research
 approaches used were both qualitative and quantitative case study approaches. The
 study population was 669 and it followed a simple random technique. Its sample size
 was 250. The collected data was summarized and analyzed by descriptive and
 inferential statistics using SPSS version 20.0 . The result then is presented in the form
 of tables and chart followed by discussions for further interpretation on the findings.
 The major findings of the study showed that employees feel that the level of basic
 salary, bonus, transparency and fairness of bonus distribution, conveyance,
 periodical increment, increments for skill upgrade, health insurance, overtime paid
 for extra work, fairness in distributing indirect financial compensation, achievement
 awards, team leadership opportunities, paid training, physical office environment,
 competence level of supervisors and people they are working with and the social
 environment at the company do not motivate them to be more productive. In
 conclusion, it’s the researcher’s strong belief that workforce productivity in the
 company will increase considerably if the company reviews its compensation
 packages. Thus, the researcher mainly recommended for the organization to develop
 a well established compensation system that mixes the financial and non-financial
 compensation practices as appropriate to be followed by a regular revision of their
 system
The Bow and Arrow Versus the Atom Bomb: Air Defence in Scotland 1945-1955
Creators: name: Gledhill, Jim
Publisher: name: British Journal for Military History
Year: 2024

description: This article proposes that the development of Britain’s air defence system in the 1950s should be viewed concurrently with that of her nuclear deterrent. Faced with a new threat from the Soviet Union in the late 1940s, Britain began engineering a new generation of anti-aircraft weapons. Using Scotland as a case study, the strategic relationship between air defence and nuclear deterrence will be explored in the British transition from a defensive to an offensive stance, and orientation toward American nuclear technologies in the late 1950s.

The German Unit of the Palmach: a suicide commando in the Second World War Palestine Mandate
Creators: name: Stoil, Jacob
Publisher: name: British Journal for Military History
Year: 2024

description: In 1942, the Special Operations Executive (SOE) partnered with the Haganah to provide irregular forces to defend the Palestine Mandate. One force, known as the German Unit, was remarkable – it was a suicide unit and required its members to shed their liberated identities and assume the personas of their former oppressors. This article examines how the unit, trained by both organisations, prepared for their task. By employing a combination of traditional sources and interviews, it explores the role of identity and restores this little known story to the historiography of the Second World War while recovering the voices of the unit.

Casualties of War: 1/1 Bucks Battalion, 1915-1919
Creators: name: Beckett, Ian

description: The handful of surviving British army ‘casualty books’ from the Great War are not only a unique source for quantifying the wartime integrity of units but also of answering such additional questions as the incidence and type of disciplinary offences. Equally, the extent of disease and illness can also be determined as well as leave policies and the impact on battalions of secondments, temporary attachments and attendance at training courses. An analysis of the casualty books of 1/1 Bucks Battalion whilst serving on the Western Front and in Italy provide a microcosm of the internal dynamics of a wartime battalion.

SBG 2015 - RNA-Seq Vitis vs Xylella - poster

description: Pierce's disease (PD) is a highly destructive disease, responsible for great losses in the North American viticulture industry. It is caused by the xylem-limited bacterium Xylella fastidiosa and characterized by blockage of xylem vessels by bacterial aggregates, which leads to water stress and chlorosis of leaf tissue, among other symptoms, affecting fruit development and overall plant productivity. However, the exact mechanisms that lead to PD development in vineyards are still poorly understood, which prompted us to employ RNA-seq analysis, in an attempt to perform a global-scale evaluation of the main metabolic alterations that occur in PD-affected plants. Thus, we inoculated four 3-month-old Vitis vinifera plants (Thompson Seedless variety) with Xylella fastidiosa (Temecula strain), which were next incubated in a greenhouse for four months. At this point, PD symptoms were clearly visible and RNA from affected leaves was extracted (Fig. 1). RNA was also extracted from theleaves of four healthy, uninfected plants that were incubated under the same conditions, to serve as control. These RNA samples were then sequenced in an Illumina platform and transcripts were mapped against the entire Vitis vinifera reference genome, with the aid of Tophat (Tab. 1). After mapping, the relative abundance of transcripts was calculated with Cufflinks and the differentially expressed genes were identified with Cuffdiff (Fig. 2). A total of 5,779 differentially expressed transcripts were obtained after this analysis, identifying several pathways that seem to be affected in diseased plants, such as photosynthesis, wax production and synthesis of chalcones, among others (Fig. 3).
The Equine Learning Curve: Horses and mules in British Army transport services during the First World War
Creators: name: Betteridge-Dyson, Lucy
Publisher: name: British Journal for Military History
Year: 2024

description: This article combines research methodologies from military history and animal studies to write equines into the history of the First World War. In doing so, it seeks to demonstrate how considering the animal perspective can advance our understanding of conflict at an individual and operational level. It proposes that the horses and mules used in British Army transport services were not just passive victims as they are often portrayed, but sentient beings who played an active role in operations.

description: Molecular dynamics (MD) simulation of [Cd(II)] along with nitrate ions and water in dodecane was carried out for different nitric acid concentrations. The extraction process using N,N,N’,N’-tetraoctyldiglycolamide (TODGA) and tributyl phosphate (TBP), in biphasic systems, is also simulated at three nitric acid concentrations. In the TBP-based system, the formation of a third phase was observed at 3 M nitric acid concentration. Cd(II) ions form reverse micelles-like clusters with TODGA as an extractant in dodecane. The mass percentage of TODGA in these clusters decreases with increase in the acid concentration while increasing the size of the aggregates at the same time.
