Naravnogeografska problematika Rakovško-Unškega polja
Authors: Lovrenčak Franc
Published: February 2020

V prispevku so zajete naravnogeografske značilnosti Rakovško-Unškega polja, ki leži v Notranjskem podolju. Poleg geoloških in reliefnih značilnosti so obravnavane tudi druge naravne sestavine te pokrajinske enote. Večji poudarek je posvečen vodnim in podnebnim razmeram ter prstem. Večletna zbiranja podatkov so pokazala, da Rakovško-Unško polje ni suho polje, saj po večji količini padavin izvira voda v več izvirih, teče po polju in ponika v ponikalnicah. Merjenja zračnih temperatur v mirnem zimskem anticiklonalnem vremenu so pokazala, da tudi na tem polju nastopa temperaturni obrat. Za prsti je značilno, da so s pedogenezo na robnih delih polja nastale na dolomitni kamnini, na dnu polja pa po vsej verjetnosti na glinasti matični podlagi. Na samem dnu polja naravne vegetacije ni več, razprostira se antropogena raba in z njo povezano rastlinstvo. Robne dele polja poraščajo travišča in gozd bora s trirobo košeničico.

Authors: Gornik Barbara , Potočnik Slavič Irma
Published: February 2020

V zadnjih dvajsetih letih je zeliščarstvo postalo večfunkcijska proizvodno-storitvena dejavnost, v kateri se prepletajo podjetništvo, tradicionalno znanje, kmetijstvo, varovanje naravnega okolja in sodoben način življenja. Ključni, relativno nov akter slovenskega zeliščarstva, so zeliščarji-podjetniki, ki na tržišče vstopajo z različnim znanjem in trženjskimi pristopi. S kvalitativno analizo polstrukturiranih intervjujev z zeliščarji-podjetniki smo za vsako podjetje izdelali kvalitativni profil in shematiziran prikaz podjetniških in trženjskih značilnosti (raznovrstnost ponudbe, prodajni kanali, možnost za širitev ponudbe, promocija, povezovanje in mreženje ter razpoložljivost delovne sile in vprašanje nasledstva). Le-te so močno odvisne od značilnosti nosilca dejavnosti, in sicer njegove starosti, zaključene formalne stopnje izobrazbe, starosti podjetja in podjetniških izkušenj ter razlogov za ustanovitev podjetja. Za uspešno delovanje zeliščarjev-podjetnikov so ključne njihove povezave z lokalnim in širšim (poslovnim) okoljem.
Economic Significance of Digital Libraries: A Structured Review
Authors: Akpokurerie Azino O. , Nina-Okpousung Marian
Published: February 2020

Traditional concept of library is mostly based on print materials; a very important part is how the introduction of technology has affected the communication and interaction between librarians and library users. In traditional libraries users have face-to-face contact with the librarians. They communicate through their eyes; they use oral or nonverbal communication such as facial expression. Presently, attention is shifting from print towards materials in electronic form. Digitalization has increased the means to make materials more readily available by adding advanced search features to access these documents.. Digital mode gives better transmission speed and quality than analog transmission. This paper defined digital libraries, their roles and advantages, their ability to meet users and library economic needs. Challenges related to inadequate finance, infrastructure and lack of expertise are among issues hindering digital libraries establishment. Recommendations made were that specific legislation and financial support be given to libraries from all tiers of government as well as consultation with right owners and other stakeholders is essential to know their peculiarity and need in establishing digital library.Keywords: digital library, library users, electronic resources, digitalization

Published: February 2020

The study was designed to investigate computer anxiety as a correlate of use of Information Technology tool by undergraduates of Library and Information Science in Tai Solarin University of Education (TASUED), Ijagun, Ogun State. Descriptive survey design was adopted while Stratified Random Sampling Technique was used to select 169 undergraduates of LIS. A questionnaire designed by the researchers was used for collecting data. Out of the 169 copies of the questionnaire administered 120 copies were returned and used for the analysis. Data was analyzed by Simple  percentages, frequency, Mean and Standard Deviation and Pearson product moment correlation. Findings show that the level of computer anxiety  among LIS undergraduates is high. The available IT tools among LIS  undergraduates are mobile technology, laptops, CD-ROM, printers and  internet search engines. The most frequency utilized IT tools among LIS undergraduate are mobile technology and laptops. The impact of computer anxiety on students’ utilization of IT tools is high. The major constraints of computer anxiety towards the utilization of IT tools among LIS undergraduates are level of computer anxiety and lack of conducive environment. A null hypothesis was tested which revealed that there is a significant relationship between computer anxiety and students’ utilization of IT tools among the LIS undergraduates surveyed. The study therefore recommends that the management of TASUED should provide more conducive learning environment, adequate IT infrastructural facilities, computer literacy should be encouraged to help lower anxiety and reduce stress in an IT environment.Keywords: computer anxiety, computer literacy, Tai Solarin University, undergraduates

Authors: Kim Junbeum , Jeon Seungjun , Song Jaeryoung , Choi Gayoung
Published: February 2020

Objective : In this study, we proposed the concept of the particulate matter footprint (PM Footprint) and assessed the PM Footprint in transportation modes (road, rail, and water transportation). In addition, we assessed the contribution of secondary particulate matter formation gas emissions, which contribute to particulate matter formation.Method : To calculate the PM Footprint in the transportation sector, the ReCiPe life cycle impact assessment method in life cycle assessment (LCA) was used. For the PM Footprint of each transportation mode, the life cycle inventory data were multiplied by the characterization factors of PM10, PM2.5 and secondary particulate matter formation emissions such as NOx, SOx, NH3. The PM Footprint values were shown in kg PM2.5 eqv. value.Results and Discussion : The road transportation (trucks) had a much higher PM Footprint value than rail and water transportation in tkm unit based. In the road transportation mode, small size truck such as 3.5 tons (1.37E-03 kg PM2.5 eqv./tkm), 3.51~5 tons (9.65E-04 kg PM2.5 eqv./tkm), 1.25 tons (8.38E-04 kg PM2.5 eqv./tkm), and 1 ton (7.83E-04 kg PM2.5 eqv./tkm) had higher PM Footprint value than big size trucks. In the rail transportation mode, the diesel rail transportation had the highest PM Footprint value, followed by electric + diesel rail transportation and electric rail transportation. In the water transportation mode, the tanker LNG_100 dwt had the highest PM Footprint value, followed by ro-ro ship coastal, and tanker coastal 500~20,000 dwt. The secondary particulate matter formation emissions (NOx, SOx, NH3) contributed to PM Footprint value with 59% in road transportation, 80% in rail transportation, and 61% in water transportation. Conclusions : The PM Footprint values, which shown in this study and the results of the directed polluted PM and secondary gas emissions should be considered for national PM reduction policy and planning. Finally, a certification system using the PM Footprint in this study should be developed and settled down for national PM reduction.

Published: February 2020

Importance: In Chinese-speaking societies, a reliable and valid measure is needed to enable early identification of young children’s challenges in sensory processing.

Objective: To examine the psychometric properties of the Chinese version of the Infant/Toddler Sensory Profile (ITSP–C) when used with Taiwanese children.

Design: Prospective study.

Setting: Multiple settings.

Participants: Participants were 367 typically developing (TD) infants ages 0–6 mo (mean [M] age = 3.44 mo, standard deviation [SD] = 1.82) and 677 toddlers ages 7–36 mo (M age = 22.33 mo, SD = 8.15), along with 42 toddlers with developmental disabilities (DD; M age = 28.4 mo, SD = 6.7).

Outcomes and Measures: The ITSP, a caregiver questionnaire that measures how children respond to sensory events in daily life, was translated and cross-culturally adapted into a Chinese version (ITSP–C).

Results: Internal consistency was high for the 0–6 mo subscale (α = .80) and the 7–36 mo subscale (α = .82). Test–retest reliability was excellent for the 7–36 mo subscale (intraclass correlation coefficient = .94). Logistic regression analysis demonstrated that the ITSP–C discriminated between children with DD and TD children.

Conclusions and Relevance: The ITSP was successfully adapted to Chinese with similar reliability and validity to the original ITSP. The 7–36 mo subscale had a higher level of reliability than the 0–6 mo subscale, and quadrant scores were more reliable than section scores. Moreover, the ITSP–C discriminated children with DD from TD children on the basis of their sensory processing patterns.

What This Article Adds: The ITSP–C has sound psychometric properties and support for its use in early identification of sensory processing difficulties in young Chinese-speaking children.

Published: February 2020

Abstract. Atmospheric aerosols play a crucial role in regional radiative
budgets. Previous studies on clear-sky aerosol direct radiative forcing
(ADRF) have mainly been limited to site-scale observations or model
simulations for short-term cases, and long-term distributions of ADRF in
China have not been portrayed yet. In this study, an accurate fine-resolution
ADRF estimate at the surface was proposed. Multiplatform datasets, including
satellite (MODIS aboard Terra and Aqua) and reanalysis datasets, served as
inputs to the Santa Barbara Discrete Atmospheric Radiative Transfer (SBDART)
model for ADRF simulation with consideration of the aerosol vertical profile
over eastern China during 2000–2016. Specifically, single-scattering albedo
(SSA) from the Modern-Era Retrospective Analysis for Research and
Application, Version 2 (MERRA-2) was validated with sun photometers over eastern
China. The gridded asymmetry parameter (ASY) was then simulated by matching
the calculated top-of-atmosphere (TOA) radiative fluxes from the radiative
transfer model with satellite observations (Clouds and the Earth's Radiant
Energy System, CERES). The high correlation and small discrepancy (6–8 W m−2) between simulated and observed radiative fluxes at three sites
(Baoshan, Fuzhou, and Yong'an) indicated that ADRF retrieval is feasible and
has high accuracy over eastern China. Then this method was applied in each grid
of eastern China, and the overall picture of ADRF distributions over eastern China
during 2000–2016 was displayed. ADRF ranges from −220 to −20 W m−2, and
annual mean ADRF is −100.21 W m−2, implying that aerosols have a strong
cooling effect at the surface in eastern China. With the economic development
and rapid urbanization, the spatiotemporal changes of ADRF during the past 17 years are mainly attributed to the changes of anthropogenic emissions in
eastern China. Our method provides the long-term ADRF distribution over eastern
China for the first time, highlighting the importance of aerosol radiative
impact under climate change.
Swarm field-aligned currents during a severe magnetic storm of September 2017
Authors: Lukianova Renata
Published: February 2020

Abstract. Swarm satellite observations are used to characterize the
extreme behavior of large- and small-scale field-aligned currents (FACs)
during the severe magnetic storm of September 2017. Evolutions of the
current intensities and the equatorward displacement of FACs are analyzed
while the satellites cross the pre-midnight, pre-noon, dusk and dawn sectors
in both hemispheres. The equatorward boundaries of FACs mainly follow the
dynamics of the ring current as monitored in terms of the SYM-H index. The
minimum latitude of the FAC boundaries is limited to 50∘ magnetic latitude (MLat). The
FAC densities are very variable and may increase dramatically, especially in
the nightside ionosphere during the storm-time substorms. At the peak of
substorms, the average FAC densities reach >3 µA m−2.
The dawn–dusk asymmetry is manifested in the enhanced dusk-side R2 FACs in
both hemispheres. In the 1 Hz data filamentary high-density structures are
always observed. In the pre-noon sector, the bipolar structures (7.5 km
width FACs of opposite polarities adjacent to each other) dominate, while at
the other local times the upward and downward FACs tend to be latitudinally
separated. The most intense small-scale FACs, up to ∼80 µA m−2, are observed just in the post-midnight sector. Simultaneous
magnetic and plasma perturbations indicate that this structure is likely a
current system of a mesoscale auroral arc.
Modal shift in North Atlantic seasonality during the last deglaciation

Published: February 2020

Abstract. Changeover from a glacial to an interglacial climate is
considered as transitional between two stable modes. Palaeoceanographic
reconstructions using the polar foraminifera Neogloboquadrina pachyderma highlight the retreat of the
Polar Front during the last deglaciation in terms of both its decreasing
abundance and stable oxygen isotope values (δ18O) in sediment
cores. While conventional isotope analysis of pooled N. pachyderma and G. bulloides shells shows a
warming trend concurrent with the retreating ice, new single-shell
measurements reveal that this trend is composed of two isotopically
different populations that are morphologically indistinguishable. Using
modern time series as analogues for interpreting downcore data, glacial
productivity in the mid-North Atlantic appears limited to a single maximum
in late summer, followed by the melting of drifting icebergs and winter sea
ice. Despite collapsing ice sheets and global warming during the
deglaciation, a second “warm” population of N. pachyderma appears in a bimodal seasonal
succession, separated by the subpolar G. bulloides. This represents a shift in the timing
of the main plankton bloom from late to early summer in a “deglacial”
intermediate mode that persisted from the glacial maximum until the start of
the Holocene. When seawater temperatures exceeded the threshold values,
first the “cold” (glacial) then the “warm” (deglacial) populations of N. pachyderma
disappeared, whilst G. bulloides with a greater tolerance to higher temperatures
persisted throughout the Holocene to the present day in the midlatitude
North Atlantic. Single-specimen δ18O of polar N. pachyderma reveals a steeper
rate of ocean warming during the last deglaciation than appears from
conventional pooled δ18O average values.

Abstract. With the development of airborne LiDAR, the use of LiDAR point cloud to construct DEM model is a hot topic in recent years. For the characteristics of time cloud filtering and poor validity, and the efficiency of non-ground point filtering is not high, the filtered point cloud has problems such as errors and leaks. This paper proposes a method of constructing DEM based on the point cloud filtering algorithm of airborne Lidar point cloud data considering special terrain. The experiment proves that the algorithm of this paper is effective for establishing DEM model, and the quality of DEM model is good.

Abstract. In recent years, with high accuracy, high frequency, considerable coverage of remote sensing images, map tiles, video surveillance, web crawlers, social networking platforms and other types of spatiotemporal data have exploded in geometric progression. Human society has come into the era of big data in time and space. In view of the characteristics of multi-attribute, multi-dimensional, multisource and heterogeneous spatiotemporal big data, how to make use of the emerging information technology means, combined with the geographic information data analysis means, the rapid mining and utilization of spatiotemporal big data has become a key problem to be solved. Built on the background of spatiotemporal big data and the process of geospatial cognition, this paper proposes a "cell-cube" spatiotemporal object data model. This paper constructs a model system of geo-spatiotemporal big data from the aspects of data organization, data storage and data partition, and abstracts the geo-space into an infinite number of geo-cells, and the adjacent geo-cells gather around the core cells to form geographical clusters, and the geographical clusters with similar attributes are clustered into geographical blocks. At the level of data organization, the spatial and temporal characteristics of structured data and unstructured data are considered as organizational dimensions, and a multi-factor extended cube data model is proposed. In the aspect of data storage, the organization model is further abstracted into the cell-cube structure of distributed data warehouse, and then the spatiotemporal data is stored uniformly. At the level of data segmentation, the mathematical table and space calculation method of multi-feature extended cube are proposed, and the geographical cell data division model based on connection is established. It solves the organization and management problem of spatiotemporal big data, provides a more complete data organization framework and solution for the application of geo-spatiotemporal big data, and promotes the development of deep mining of spatiotemporal extensive data in GIS. And to achieve space-time big data in the geographical space microscopic and the macroscopic unification cognition.

Published: February 2020

Abstract. Urban planning and constructions affect spatial patterns of urban impervious surfaces, which in turn modify the urban environment and affect human-environment interactions. Impervious surfaces can redistribute precipitation patterns, and the perviousness–imperviousness ratio is considered as one important indicator for assessing the degree of urbanization and the quality of urban eco-environment. The spatial distribution and dynamics of impervious surfaces contribute to better understand urbanization and its impacts on regional or urban hydrological environment, surface temperature balance and biodiversity, etc. Hengqin new area is located in Hengqin island, south of Zhuhai city, adjacent to Hong Kong and Macao. It was officially established as a free trade zone in 2009. Due to the rapid development of Hengqin in recent years, this paper discusses Landsat8 imagery of time series in mapping impervious surfaces, and analysis the changes of impervious surface in Hengqin from 2013 to 2018. Support vector machine (SVM) is a classical classifier that is supervised learning models and that use related learning algorithms to analyze data for classification and regression analysis (Vapnik, 1995). In this paper, we obtain the impervious surface distribution via SVM and get good accuracy. The impervious surface distribution of Hengqin in six years show that the quickly improve of urbanization level. However, with the development of urbanization, the impervious surface has not changed dramatically, which shows that the decision-making of urban managers is correct. After the urbanization construction in Hengqin, it is still an ecological island.

Authors: Li J. , Wei B.
Published: February 2020

Abstract. With the advancement of urbanization, urban-rural public transport issues have become one of the most critical issues in urban development. The paper makes a detailed study on the optimization of urban-rural bus routes in Erqi District of Zhengzhou, China. The factors of bus stop selection are analyzed, and the three categories, including traffic road condition factors, economic benefit factors and waiting number factors, are mainly considered. The analytic hierarchy process is used to determine 35 specific objectives of urban-rural bus stop optimization, 20 of which are selected for simulation experiment with large weight. Then the ant colony optimization (ACO) algorithm in path optimization is analyzed, which has the following two advantages. First, the global pheromone update is combined with the local pheromone update to enhance the algorithm's optimization ability and convergence speed. Second, through the method of spatial contraction transformation, the ant constructs a solution to reduce the number of construction steps and speed up the operation. Based on the actual analysis of urban-rural public transportation in the Erqi District of Zhengzhou, a simulation experiment is executed to show that the ACO algorithm is able to find out the optimal path, which is 15.1% shorter than the ant colony system (ACS) algorithm. The ACO algorithm improved path planning has good time effectiveness and path practicability.

Published: February 2020

Abstract. The ideal radiometric calibration site is the basis for achieving on-orbit radiometric calibration. At present, China mainly uses the Dunhuang national test site for on-orbit radiometric calibration. However, the Dunhuang national test site has a shortage of ground objects and surface damage, and it is urgent to select and evaluate the new calibration sites. By analyzing the calibration site selection requirements, three new radiometric calibration sites were selected in Dunhuang and Golmud. Obtaining high-resolution satellite image data of each calibration site and evaluating the spatial uniformity of the site on different spatial scales. The radiometric stability of the sites is evaluated using the long-term sequence of Landsat8 image data from 2013 to 2019. Atmospheric and surface tests were carried out at various sites in August 2019, and atmospheric information and ground spectral data were obtained to evaluate the spectral characteristics of the sites. The surface directional characteristics of the sites are evaluated by using MODIS images at different angles in sunny weather on adjacent dates. Obtaining MOD05 water vapor products from 2013 to 2019 of each calibration site and conducting monthly statistics. The number of sunny days at each calibration site is counted and the drought conditions of the site are evaluated. The results show that the three new radiometric calibration sites have uniform and stable surface characteristics and atmospheric characteristics, and are suitable for on-orbit radiometric calibration of satellite sensors, which provides a reference for the location and evaluation of future calibration sites.

Abstract. The survey and monitoring system of natural resources is the basis for finding out and monitoring the background data in the new era. The classification standard is an important cornerstone in the survey and monitoring system. The classification standard appears in the whole process of natural resources, such as survey, monitoring, evaluation, planning and control etc. Classification results are widely used in natural resource asset management, territorial space use controlling, ecological protection and restoration. Therefore, only a classification standard with the unified, scientific and practical characteristics is constructed, a survey and monitoring system with “six unifications” can be built. This paper refines the existing status and the main problem of existing classification standards, and then puts forward the construction ideas and three suggestions for the new classification standards, which hoping to provide a reference for local survey and monitoring pilots and national classification standard construction.

Authors: Gao J. , Zhou G. Q. , Wang H. Y. , Zhou X. , Mu Y. X. , Long S. H. , Yang F.
Published: February 2020

Abstract. The evaluation of the bathymetric capability of traditional airborne lidar system is mostly based on the formula of bathymetric capability by evaluating the diffuse attenuation coefficient (Kd). This method is derived form the assumption that the reflectance of sediment is fixed. In this study ,however,the reflectance of sediment is not fixed. Therefore, this study improves the ability of bathymetric formula, and proposes a particle scattering classification algorithm to obtain the transmissivity value. The algorithm filters the scattering modes of particles by scattering discrimination factor (q), and obtains the transmissivity values by using the scattering intensity formulas. Experiments show that, when the transmissivity is in the range of 0–1 and the average values of Kd(532 nm) are 0.1150 m−1, 0.0894 m−1 and 0.0903 m−1 in January, June and October respectively, accordingly, the bathymetric capabilities are 0–44 m, 0–61.5 m and 0–52.5 m, respectively. Compared with the original bathymetric method, these results show that the maximum bathymetric value has measured by the improved bathymetric capability formula and scattering classification algorithm has decreased under the influence of the change of sediment reflectance, and the result is more consistent with the actual situation and more accurate.
HoloPort – design and integration of a digital holographic 3-D sensor in machine tools
Authors: Seyler Tobias , Engler Johannes , Beckmann Tobias , Fratz Markus , Bertz Alexander , Carl Daniel
Published: February 2020

Abstract. Manufacturing of high-precision components requires accuracies that even the most modern processing machines are often unable to deliver reliably. Slightly worn tools, incorrectly calibrated sensors or even different trajectories can lead to results that do not comply with the desired specifications. However, quality control is still mainly performed on randomized samples outside the machine tool in special measuring rooms. Therefore, closed-loop quality control becomes a cumbersome iterative process. With HoloPort, we present a digital holographic sensor system that is capable of measuring the complete topography of machined components with sub-micrometer precision directly inside a tooling machine. To our knowledge, HoloPort is
the first wireless interferometric sensor inside a machine tool worldwide.
As it is fully integrated, it features not only a multiwavelength interferometer but also a miniaturized graphics processing unit (GPU). This allows for full data evaluation directly in the sensor. A single measurement is taken and processed within 3 s during wireless operation. HoloPort is easy to integrate into a variety of machine tools. This contribution includes detailed information about the sensor architecture. Experimental results on milled parts demonstrate the performance of the system and illustrate possible inline applications as well as future perspectives for the sensor.
Strain response and energy dissipation of floating saline ice under cyclic compressive stress
Authors: Wei Mingdong , Polojärvi Arttu , Cole David M. , Prasanna Malith
Published: February 2020

Abstract. Understanding the mechanical behavior of sea ice is the basis of ice mechanics applications. Laboratory-scale work on saline ice has often involved dry, isothermal ice specimens due to the relative ease of testing. This approach does not address the fact that the natural sea ice is practically always floating in seawater and typically has a significant temperature gradient. To address this important issue, we have developed equipment and methods for conducting compressive loading experiments on floating laboratory-prepared saline ice specimens. The present effort describes these developments and presents the results of stress-controlled cyclic compression experiments. We conducted the experiments on dry, isothermal (−10 °C) ice specimens and on floating ice specimens with a naturally occurring temperature gradient. The experiments involved ice salinities of 5 and 7 ppt, cyclic stress levels ranging from 0.04–0.12 MPa to 0.08–0.25 MPa and cyclic loading frequencies of 10−3 Hz to 1 Hz. The constitutive response and energy dissipation under cyclic loading were successfully analyzed using an existing physically based constitutive model for sea ice. The results highlight the importance of testing warm and floating ice specimens and demonstrate that the experimental method proposed in this study provides a convenient and practical approach to perform laboratory experiments on floating ice.

Published: February 2020

Online Social Networks (OSNs) are based on actual trust relationships in environments which help people communicate with friends, family and acquaintances. Malicious individuals take advantage of this trust relationship to propagate malware through social networks. We study the dynamics of malware propagation among OSN users. Social networks users are referred to as nodes which is in two compartments: Healthy (H), or Infected (I). A H node could either be susceptible to infection (S) or removed (R). Simulations were carried out in R using the EpiModel network simulation package. Two networks were simulated thrice with different parameters to give better average values. Two categories of nodes, first category comprises of 3000 nodes with fewer connections and the second category comprising of 7000 nodes are the influential nodes with more connections. The larger network tends to have a higher fraction of nodes getting infected per unit time due to the high level of connectivity, as opposed to the small network where the number of connections is few. However, the infection tends to persist in the network as long as the birth rate is not equal to zero.
Water Use Efficiency Differences in Maize Varieties under Every Furrow and Alternate Furrow Irrigation
Authors: Fandika Isaac R. , Chipula Grivin , Mwepa Geoffrey
Published: February 2020

Water-use efficiency (WUE) differences of selected maize varieties under alternate and every furrow irrigation were investigated in a split-plot design trials with three replicates. Alternate furrow (AFI) and Every furrow irrigation (EFI) were main treatments and twenty maize varieties were sub-treatments. Plots were 64 m2 with one maize seed per station spaced at 0.25m apart. Crop water use results indicated that EFI consumed more water than the AFI. The AFI reduced crop water consumption by 38 - 45% compared to EFI.  Differences were also prominent in maize varieties’ response to AFI. Late maturing maize varieties proved to have minor yield reduction with AFI compared to early and medium maturing maize varieties. WUE (kg m-3) differed with irrigation water application strategy (P<0.001). AFI had high WUE. A combination of AFI with selection of water efficient maize varieties was a good strategy for improving WUE. The AFI is a promising furrow irrigation water management strategy for water saving. According to farmers experience at five irrigation schemes and on station research, it was concluded that AFI is one of the climate smart irrigation technique that farmer can easily adopt and apply as it saves labour, time water whilst reducing conflict for water among irrigators. It was recommended that AFI be applied fully on early and medium maturing maize varieties within an irrigation interval of 7 days. For late maturing maize varieties, AFI technique should be applied from initial stage to mid - stage (up 55 days from planting) then apply EFI at tasselling and silking stages to reduce water stress at this critical stage.

Incisional ventral hernia occurs after almost every fourth laparotomy. Still, both simple suturing of the hernia defect and open mesh repair, leads to high incidence of infections and recurrences.
In recent years we observe a further evolution of the operational techniques used, in order to reduce the number of complications. The search for effective repair methods is currently going in two directions: on the one hand, techniques to reduce tissue tension in the suture line are being developed and disseminated (including modifications to the so-called Ramirez technique); on the other hand, minimally invasive techniques are introduced that allow placement of large synthetic meshes without the need for extensive tissue dissection using the open repair.
In the first group of presented techniques the emphasis is put on basics and access in the following repair method: original Ramirez technique, modified Ramirez technique, anterior component separation with periumbilical perforators sparing, endoscopic anterior component separation and transversus abdominis release.
In the second part of the manuscript the attention is drawn to the following hernia repair techniques: eTEP, reversed TEP, MILOS/eMILOS, stapler repair, TAPP, TARUP, TESLA, SCOLA, REPA, LIRA, IPOM, IPOM-plus.
When choosing the optimal technique for a given patient, a surgeon should first of all be guided by technical feasibility, availability of materials, his/her own experience, as well as the characteristics of the patient and overall burdens present. Nevertheless, surgeons undertaking reconstruction of the abdominal wall in the case of hernias should know different surgical accesses and individual spaces of the abdominal integument, in which a synthetic material may be placed. However, it should be emphasized that the poor ergonomics of novel techniques, complex anatomy and complicated dissection of space, as well as the need for laparoscopic suturing in a difficult arrangement of tissue layers and in a narrow space, without a full triangulation of instruments, make these operations a challenge even for a surgeon experienced in minimally invasive operations.

Design of Three-Term Controller Using a PIC18F452 Microcontroller
Authors: Ghassoul Mostefa
Published: February 2020

Microcontrollers are used in almost any applications that come across one’s mind, from small control applications such as home appliances to aerospace. Microcontroller-based controllers are cost-effective and flexible to modify the design to meet the requirement for any control of any industrial plant. Microcontrollers do not require external hardware interface, memories, counter/timers, and ADCs, because they are all integrated inside the chip. Those controllers could be programmed online and do not require any backup memories except for big applications. This chapter presents the implementation of the three-term PID controller using a Microchip PIC18F452 microcontroller. To read data into the controller, a 10-bit integrated ADC is used; and to read data out of the machine, an external 12-bit serial DAC is used. Before programming the PIC microcontroller, the task to be tested could be off-line using a software simulator to make sure that it is working according. When that is the case, it could be then fired into the controller on-line in a mater seconds. Not only that, if the user decides to use different algorithm, he only programs the controller again online.
Renal Infarct After Endovascular Abdominal Aortic Aneurysm Repair: Consider in Back Pain Differential
Authors: Liu Sophia , Hackett Anthony
Published: February 2020

As hypertension, obesity, and hyperlipidemia become more widespread, the prevalence of abdominal aortic aneurysms (AAA) has also increased. Traditionally those with multiple comorbidities – also those with greatest AAA mortality – were considered too high risk for operative repair. In recent decades, however, endovascular abdominal aortic aneurysm
repair (EVAR) has become a popular option, especially for high-risk patients. Overall, short-term outcomes are comparable to traditional open repair despite higher patient baseline risk. However, EVAR comes with its own risks, which the emergency physician should be aware of. Here, we present a rare complication of EVAR: device thrombosis with subsequent renal infarct.
Pericardial Tamponade After Systemic Alteplase in Stroke and Emergent Reversal With Tranexamic Acid
Authors: Romero Cynthia , Shartar Samuel , Carr Michael
Published: February 2020

Alteplase, or tissue plasminogen activator (tPA), lyses clots by enhancing activation of plasminogen to plasmin. Conversely, tranexamic acid (TXA) functions by inhibiting the conversion of plasminogen to plasmin, which inhibits fibrinolysis. TXA has proven safe and effective in major bleeding with various etiologies. A 76-year-old male developed acute ischemic stroke symptoms. Systemic alteplase was administered and he showed clinical improvement. Shortly thereafter, the patient became hypotensive and lost pulses. Point-of-care ultrasound revealed cardiac tamponade. TXA was immediately given to inhibit fibrinolysis since cryoprecipitate and blood products were not immediately available. Pericardiocentesis was performed and successfully removed 200 milliliters of blood with return of pulses. Clinicians must consider TXA as a rapidly accessible antagonist of tPA’s fibrinolytic effects.
New Reduction Technique for Traumatic Posterior Glenohumeral Joint Dislocations

Published: February 2020

Traumatic posterior glenohumeral joint (GHJ) dislocation is a rare condition which can be missed if it is not suspected. Clinical presentation may be subtle, but limitation in range of motion in patient with acute trauma should warrant obtaining a thorough history, performing a comprehensive physical examination, and acquiring at least a 3-view plain radiography. Reduction can be achieved with a direct pressure to the posterior aspect of the humeral head.

Published: February 2020

The clinical presentation of diabetic ketoacidosis in pregnancy (DKP) is similar to that observed in nonpregnant women, although reports suggest the presenting blood glucose level may not be as high. It is hypothesized that lower, maternal fasting glucose levels are a result of both the fetus and the placenta consuming glucose. We report the case of a 38-year-old woman gravida 2, para 0, abortion 1 with type 1 diabetes who had euglycemic diabetic ketoacidosis and review the literature on DKP, with a focus on diagnosis, treatment, and monitoring of the mother and fetus.

Non-pharmacologic treatments of Sleep-Related Movement Disorders (SRMD) are already well described in the literature. The physical activity has been presented as a factor to improve quality of life and in several aspects related to sleep disorders. Thus, the purpose of this review was to analyze the benefits of physical exercise and your indication to improve to SRMD. In the research, 19 studies were found that evaluate the efficacy of physical exercise on SRMD in both human and animal models. The results demonstrate that both acute and chronic physical exercises are effective in reducing symptoms of SRMD. However, most studies were performed with aerobic exercise. Three studies evaluated the efficacy of combined exercise, and no studies have investigated the relationship of resistance exercise. Regarding the mechanisms involved, a study discusses the relationship between the release of beta-endorphin and the exercise practice, and two studies with animal models show the changes of the dopaminergic system after physical exercise. From this evidences, we suggested that physical exercise is a favorable non-pharmacological treatment for SRMD. However, more studies should be available for a better understanding of the molecular mechanisms involved, as well of the type, duration and better time of the day to practice.
