Published: January 2020

The number of disabled students is rapidly increasing worldwide, but many schools and universities have failed to keep up with their learning needs. Consequently, large numbers of disabled students are dropping out of school or university. Open Educational Resources (OER) and Open Educational Practices (OEP) contain several relevant features, including the possibility of reusing and remixing, which have led researchers to consider using OER and OEP to facilitate meeting the needs of disabled and functional-diverse students in order to increase their accessibility and e-inclusion capabilities in educational settings. The very limited research to date, however, has provided a limited holistic understanding of accessibility within OER and OEP in order to aid researchers in pursuing future directions in this field. Therefore, this paper systematically reviewed 31 papers to provide insights about functional diversity within OER and OEP. The results obtained highlighted that accessibility is still in its infancy within OER and that researchers should focus more on considering the four accessibility principles — perceivable, operable, understandable and robust — when providing OER. Additionally, while several researchers have focused on several issues related to accessibility within OER, limited focus has been given to assistive technologies using OER. Finally, this paper provides several recommendations to increase accessibility within OER and help design more accessible OER for students with functional diversity.

Background

Myeloid sarcoma (MS) is a solid tumor consisting of myeloid blasts or immature myeloid cells, which are unusual outside the bone marrow.

Case presentation

We present a rare case of isolated myeloid sarcoma of the small bowel in a 54-year-old man who was admitted to our hospital with repeated symptoms of intestinal obstruction. A small bowel series via an ileus tube revealed severe jejunal obstruction. Computed tomography revealed that the obstruction was likely caused by a jejunal tumor. The patient underwent laparoscopy-assisted partial resection of the jejunum with lymphadenectomy. Histopathological examination of the surgical specimen confirmed that MS had been responsible for the obstruction.

Conclusions

Patients with MS require systemic chemotherapy, as do patients with acute myeloid leukemia. Hence, an early, accurate diagnosis is imperative for treating this malignancy. It is also important to list MS in the differential diagnosis of a small bowel tumor, even in nonleukemic patients.
Numerical simulation of CO2 huff-and-puff process in a hydraulically fractured horizontal well in a tight oil reservoir
Authors: Jia Xiaohan , Luo Mingliang , Pu Hui
Published: January 2020

A numerical reservoir model was built using Computer Modeling Group's GEM simulator to study the process of carbon dioxide (CO2) huff-and-puff in the Bakken tight formation. The influences of injection rate, production time, and soaking time on the incremental oil recovery factor (IORF) were studied systematically, as was the utilization efficiency of CO2 during the whole production process. The results showed that higher injection rates are preferable to lower ones, and the huff-and-puff process works best with a soaking time of 0 days. The production time of each cycle could be optimized for a specific case to maximize IORF, and CO2 efficiency was found to decrease with increasing number of cycles. This study may shed light on how to optimize the CO2 huff-and-puff process and therefore achieve the best enhanced oil recovery performance.
Monitoring the fate of injected CO2 using geodetic techniques
Authors: Vasco Donald W. , Dixon Timothy H. , Ferretti Alessandro , Samsonov Sergey V.
Published: January 2020

Geodetic methods comprise one class of geophysical data that are sensitive to changes in effective pressure within operating reservoirs, albeit indirectly through induced deformation. Geodetic observations, which have observation intervals that vary from seconds to days, weeks, or months, generally provide more frequent sampling compared to existing geophysical methodologies (such as seismic time-lapse monitoring), which typically invoke repeat times of months to years. These differences in sampling intervals are primarily due to the extensive effort, and hence cost, of conducting geophysical field operations, which often precludes executing a large number of surveys. Satellite-based interferometric synthetic aperture radar (InSAR) is cost effective and used in many applications, including monitoring the injection of carbon dioxide (CO2) for both long-term storage and enhanced oil production. An application to the geologic sequestration of CO2 in Algeria revealed northwest migration along a fault/fracture zone intersected by the injection well. A study in a Texas field demonstrated that enhanced oil recovery utilizing CO2 leads to observable surface deformation that may be used to characterize the sequestered CO2 and to estimate the pressure changes within the reservoir induced by injection and production.
Addressing artifacts in PP-PS registration prior to performing joint impedance inversion
Authors: Chopra Satinder , Sharma Ritesh Kumar
Published: January 2020

Multicomponent seismic data analysis enhances confidence in interpretation by providing mode-converted PS data for imaging the subsurface. Integrated interpretation of PP and PS data begins with the identification of reflections corresponding to similar geologic events on both data sets. This identification is accomplished by carrying out well-log correlation through the generation of PP and PS synthetic seismograms. There are a few issues associated with the approach. One of the issues is that PS data have lower resolution than PP data. This presents difficulties in the correlation of equivalent reflection events on both data sets. Even if few consistent horizons are tracked, the horizon-matching process introduces artifacts on the PS data mapped in PP time. In this paper, we elaborate on such challenges with a data set from the Anadarko Basin in the United States. We then propose a novel workflow to address the challenges.
Value of a second seismic monitor in late stages of field development at Holstein
Authors: Zouari Mehdi , Perez Maria , Chen Jianxiong , Kimbrough Allison , Salathe Lauren , Gandhi Namrita
Published: January 2020

A second seismic monitor survey acquired after nine years of production at Holstein Field was used successfully to define new wellbore sidetracks to target unswept areas in two of the main producing reservoirs (J2 and K1). The asset team and the technology group worked together to investigate the quality and interpretability of the 4D signal between the first and second monitor surveys. The method consisted of conducting a quality check of the acquisition and processing steps, modeling the amplitude variation with offset responses using existing wells to determine the response to fluid effects, and finally extracting and creating amplitude difference maps between monitor surveys for each reservoir. The interpretation of the 4D amplitude differences, combined with the analysis of production and pressure data from historical injector and producer wells, resulted in the decision to target what was interpreted to be a partially swept J2/K1 reservoir compartment by the aquifer in the southern part of the field. Well #12 was drilled in that target and encountered oil pay in both reservoirs, with low levels of water saturation. Another J2 area in the northern part of the field was interpreted to have remained partially unswept by water injectors, although seismic acoustic softening over that portion of the field suggested that it was still benefiting from injection pressure support. Well #11 was drilled in that northern portion of the field and encountered an oil-bearing reservoir with water saturation near preproduction levels and a reservoir pressure approaching original reservoir pressure, hence confirming repressurization.

The Effect of Auditing on Promoting Exports: Evidence from Private Firms in Emerging Markets
Authors: Cheng C. S. Agnes , Sun Weihang , Ye Kangtao , Zhang Ning
Published: January 2020

We investigate the effect of auditing on promoting exports for private firms in emerging markets. Using a sample of private firms from 125 countries between 2006 and 2015, we show that firms that have their financial statements audited have more exports than firms that do not have their financial statements audited. To infer causality, we employ a regression discontinuity design (RDD). Using the discontinuity around the mandatory financial audit threshold, we find that firms slightly above the threshold have more exports than do firms that are slightly below the threshold. We also exploit the countries with exogenous regulation shocks to the mandatory audits. Using the difference-in-differences (DiD) design, we find that firms that are exempted from mandatory audits have less exports subsequent to the regulation change. Further analyses reveal that the effect of auditing is more pronounced in countries with higher audit quality and for firms with limited alternative information. Our findings suggest that the auditing function promotes exports—an important economic consequence for the global economic development.

Authors: Riza Muh Wahid Anshori
Published: January 2020

The lack of a disaster information system nowadays has made it difficult to find out information in the disaster area. Making information systems in disaster areas is important to solve the problem of uneven distribution of aid provided at each barrack. Because the conditions of each barrack are different, a system is needed to determine the priority for selecting disaster. To be able to determine the recommendations for the selection of disaster barracks, this study uses the Fuzzy Simple Additive Weighting (Fuzzy SAW) method, uses fuzzy method to determine the input basis value to SAW [3]. With the implementation of the Fuzzy SAW method, the results of this study can provide recommendations for Badan Penangguangan Bencan Daerah (BPBD) of Malang to determine the priority of disaster barracks that can take precedence.

Dynamic routing, spectrum, and modulation-format allocation in mixed-grid optical networks
Authors: Ahmed Tanjila , Rahman Sabidur , Ferdousi Sifat , Tornatore Massimo , Mitra Abhijit , Chand Chatterjee Bijoy , Mukherjee Biswanath
Published: January 2020

Traffic in optical backbone networks is evolving rapidly in terms of type, volume, and dynamicity following the rapid growth of cloud-based services, ongoing adoption of 5G communications, and explosion of the Internet of Things (IoT). The elastic optical network (EON), by adopting a flexible grid, can provide the required capacity and flexibility to handle these rapid changes. However, operators rarely perform greenfield deployments, so to limit upfront investment, a gradual migration from fixed-grid to flexible-grid switching equipment is preferable. For gradual migration, switching nodes can be upgraded (starting from bottleneck network links) while keeping the rest of the traditional fixed-grid network operational. We refer to the coexistence of fixed-grid and flex-grid optical equipment as a “mixed-grid” network. Traditional algorithms for dynamic resource assignment in EONs will not effectively be applicable in a mixed-grid network due to interoperability issues among fixed- and flex-grid nodes. In this study, we propose a new algorithm, called Mixed-grid-aware Dynamic Resource Allocation, to solve the route, spectrum, and modulation-format allocation problem in a mixed-grid network while considering interoperability constraints. Our numerical results (on representative network topologies) show that the proposed method achieves 50% less blocking (for 50% offered load) compared to the traditional approach.
Probability of error for detecting a change in a parameter and Bayesian Fisher information
Authors: Clarkson Eric
Published: January 2020

The van Trees inequality relates the ensemble mean squared error of an estimator to a Bayesian version of the Fisher information. The Ziv-Zakai inequality relates the ensemble mean squared error of an estimator to the minimum probability of error for the task of detecting a change in the parameter. In this work we complete this circle by deriving an inequality that relates this minimum probability of error to the Bayesian version of the Fisher information. We discuss this result for both scalar and vector parameters. In the process we discover that an important intermediary in the calculation is the total variation of the posterior probability distribution function for the parameter given the data. This total variation is of interest in its own right since it may be easier to compute than the other figures of merit discussed here.
Generalized Talbot self-healing and noise mitigation of faulty periodic images
Authors: Romero Cortés Luis , Guillet de Chatellus Hugues , Deville Antonin , Seghilani Mohamed , Hamam Ines , Azaña José
Published: January 2020

Obtaining high-quality images from physical systems, objects, and processes is fundamental for a myriad of areas of science and technology. However, in many situations, the measured images contain defects and/or are accompanied by noise, degrading the quality of the measurement. Recently, a variant of the well-known Talbot self-imaging effect has been shown to redistribute the energy of a spatially periodic collection of images, obtaining output images with increased energy with respect to the input ones. In this work we experimentally demonstrate that such an energy redistribution method has the unique capabilities of increasing the coherent energy level of a periodic set of images over that of the incoherent noise, even allowing images completely buried under noise to be recovered. We further demonstrate that the process can mitigate potential faults of the periodic image structure, including blocked images, spatial jitter, and coherent noise, offering important enhancements (e.g., in regards to the quality of the recovered individual images) in the self-healing capabilities of Talbot self-imaging.
Pupil response is modulated by attention shift in optokinetic nystagmus
Authors: Kanari Kei
Published: January 2020

Pupil size is modulated not only by the luminance at the eye position but also by that at the attended location. This study aims to examine whether pupil changes also correspond to the luminance at the spatial location to which the attention is shifted in optokinetic nystagmus. The test stimulus consisted of randomly positioned dots that moved to the left or to the right on a display screen that was bright on one side of the centerline and dark on the other. The results show that pupil size changes in accordance with the luminance at the location to which participants’ attention shifts as a result of optokinetic nystagmus (i.e., eye movements in the direction opposite to that of the motion stimulus). This study suggests that pupil size is modulated by the luminance at the location to which attention shifts through unidirectional field motion.

Published: January 2020

The moiré effect in 3D objects with planar facets is considered. The projected period of the inclined periodic grating was found. The formula for the period of the moiré patterns in inclined plain surfaces was obtained for objects with arbitrary oriented plain facets, namely, the parallelepiped and the prism (parallel and non-parallel facets). The similarity between the projected period and the moiré period was demonstrated. The direction to the longest moiré pattern in the wedge was found theoretically and observed in experiments. The results can be used in the alignment of flat surfaces.
Gaussian beam solutions in a longitudinally varying medium with a transverse quadratic-index profile
Authors: Yeo Joel , Li Hao
Published: January 2020

Research in laser–plasma interaction, high harmonic generation, and filamentation involves Gaussian beams propagating through inhomogeneous media, where the refractive index varies spatially in both the transverse and longitudinal directions. However, most analytical Gaussian beam solutions to the paraxial wave equation for inhomogeneous media are limited to media with the refractive index only varying quadratically in the transverse direction. In this paper, we present a new class of Gaussian beam solutions for a longitudinally varying medium with a transverse quadratic-index profile. We also highlight a few examples from this class of solutions, which include features such as a one-parameter generalization of the free-space Gaussian beam, beam “collimation,” beam self-focusing, and the existence of multiple beam waists.

Published: January 2020

We demonstrate a simple technique to lock the frequency of a laser to an atomic transition with a new technique of subnatural linewidth spectroscopy. The coupled rubidium system exhibits an enhanced absorption spectrum of the probe beam with a subnatural linewidth. Compared with other techniques with an additional laser, our scheme only utilizes a single laser, which will be locked. The observed spectroscopic linewidth is down to about 3.5 MHz. The laser frequency fluctuation is about 226 kHz after locking on. The demonstrated scheme offers a convenient and low-cost technique for laser frequency stabilization and related precision measurements.
New testing and calculation method for determination viscoelasticity of optical glass

Published: January 2020

Viscoelastic properties of glass within molding temperatures, such as shear relaxation modulus and bulk relaxation modulus, are key factors to build successful numerical model, predict forming process, and determine optimal process parameters for precision glass molding. However, traditional uniaxial compression creep tests with large strains are very limited in obtaining high-accuracy viscoelastic data of glass, due to the declining compressive stress caused by the increasing cross-sectional area of specimen in testing process. Besides, existing calculation method has limitation in transforming creep data to viscoelasticity data, especially when Poisson’s ratio is unknown at molding temperature, which further induces a block to characterize viscoelastic parameter. This study proposes a systematic acquisition method for high-precision viscoelastic data, including creep testing, viscoelasticity calculation, and finite element verification. A minimal uniaxial creep testing (MUCT) method based on thermo-mechanical analysis (TMA) instrument is first built to obtain ideal and accurate creep data, by keeping compressive stress as a constant. A new calculation method on viscoelasticity determination is then proposed to derive shear relaxation modulus without the need of knowing bulk modulus or Poisson’s ratio, which, compared with traditional method, extends the application range of viscoelasticity calculation. After determination, the obtained viscoelastic data are further incorporated into a numerical simulation model of MUCT to verify the accuracy of the determined viscoelasticity. Base on the great consistence between simulated and measured results (uniaxial creep displacement), the proposed systematic acquisition method can be used as a high accuracy viscoelasticity determination method.
Fiber endface illumination diffuser for endo-cavity photoacoustic imaging
Authors: Luo Hongbo , Yang Guang , Zhu Quing
Published: January 2020

The laser illumination delivery method is important in designing probes that achieve high imaging quality and deep tissue penetration. Here we present a novel, to the best of our knowledge, fiber diffuser tip using microspheres dispersed within an ultraviolet adhesive to scatter light. This diffuser keeps the skin surface fluence under the maximum permissible exposure, while enabling higher laser energy injection to enhance the photoacoustic (PA) signal generated from the tissue. We compare the light diffusion effects of different microsphere materials, sizes, and concentrations, and find that 10 µm silica microspheres provide the best light scattering with minimal 5% output energy loss. With the Zemax simulation and experimental validation, we show that this fiber diffuser tip is a valuable tool for endo-cavity PA imaging.
Pancharatnam–Berry geometric phase memory based on spontaneous parametric down-conversion

Published: January 2020

Phase memory is an effect in which the interaction between a coherent pump beam and a nonlinear crystal generates photon pairs via the spontaneous parametric down-conversion process, then the down-converted photons (signal and idler) can carry the phase information of the pump beam. There has been much research on the memory of the dynamic phase so far; however, there is no report on the memory of non-dynamic phase, to the best of our knowledge. Here we acquire a Pancharatnam–Berry (PB) geometric phase in a physical system when light travels along a trajectory in polarization-state space. Induced coherence occurs in a cascaded scheme composed of two nonlinear crystals, when the idler photons in both crystals are aligned to be indistinguishable. A NOON (

N

=

) state is established when blocking the two idler photons. We explore the PB geometric phase memory of the NOON state and induced coherence. We find that the first-order interference of the two-photon state or signal photons can be controlled by introducing the PB geometric phase to the pump light. This may facilitate precise control of the phase of the down-converted photons.
3D dark-field confocal microscopy for subsurface defects detection
Authors: Liu Jian , Liu Jing , Liu Chenguang , Wang Yuhang
Published: January 2020

The three-dimensional (3D) precision measurement of subsurface defects (SSDs) remains a long-term, critical, and urgent challenge in advanced manufacturing technology. In this study, we present a 3D dark-field confocal microscopy technique with complementary illumination and detection apertures to detect the SSD in ultraprecise optical components, which are widely employed at laser fusion facilities. Under an annular illumination generated using a pair of axicons, the specular reflected beam from the surface can be blocked by a diaphragm placed in the detection path, while the scattered beam from the SSD can be effectively collected by the detector. Both surface topography and subsurface defects distribution can be measured simultaneously by this method. We constructed a dark-field confocal microscope that could readily detect the SSD 60 µm beneath the surface in neodymium glass. Furthermore, the 3D volume distributions of the SSD were also reconstructed.

This chapter details the Netherlands' introduction to African American blues music. Most people believe that that the Netherlands' first became acquainted with African American blues music in the second half of the 1960s, during the American Folk Blues Festivals (AFBFs). However, AFBF of 1965 was not the first blues concert in the Netherlands. That privilege fell to the guitarist/singer Big Bill Broonzy, who more than a decade earlier had conquered the Netherlands on his own. The chapter also describes the beginning of the Dutch blues era in 1926 and Amsterdammer Frans Boom's attendance of Duke Ellington concert in 1939.

O presente trabalho tem o objetivo de identificar as primeiras experiências de comercialização de alimentos agroecológicos em Pernambuco, que posteriormente, no ano de 1997, tornar-se-ia o Espaço Agroecológico, bem como analisar a conjuntura que levou a criação das duas primeiras feiras que o compõem. Após os agricultores adotarem a agroecologia, houve a necessidade da construção de um canal autônomo, distante dos antigos meios de escoamento, que eram as feiras livres e os “atravessadores”, intermediários que, em grande parte dos casos, exploram os agricultores pagando um preço muito abaixo do mercado. O artigo mostra a importância dos mercados paralelos, tendo como modelo a primeira feira de produtos agroecológicos do Recife/PE/Brasil: Espaço Agroecológico do bairro das Graças.

Published: January 2020

Food delivery services become more popular in Indonesia, which is proven by the number of restaurants that provide delivery services such as KFC, Mc Donald, and others. They are still using the phone to serve the customers. For customers, ordering by phone is less interactive since they cannot see the display of available menus with the prices and other details. For the cashiers, ordering by phone is also less effective since they have to write the menus, prices and addresses manually, whereas nowadays we need automation and the speed becomes a very important factor. This system is using Mobile Web technology and Geographical Information System (GIS), which with this technology the customers can order anywhere, and the order pages will be more interactive. For the cashiers, with this GIS, they do not need to record the data order manually. For food deliver, with the technology of GIS, food delivery processes will become easier due to the visualization of the location of customers, and they also can use the existing tracking features in GIS. The system implements the concept of client-server where the server website is used by restaurants, and mobile websites as client are used by customers for ordering food. The Web server has a notification ordering feature, administrator management, menus management, order management, suggestion management, restaurant management, and financial reports. Client's website has a food order feature, geolocation, and send suggestions features to the restaurant.

ANIMAL TURN AS A META-TURN?
Authors: MAMZER HANNA
Published: January 2020

Human sciences as a reflection of social transformations fluctuate with dynamic changes of current cognitive paradigms. Following the textual and visual turn and the turn towards things (objects), there are intensified tendencies to think in terms of an “animal turn”, which becomes close not only to activists and pro-animal activists but also to scientifically engaged humanists. I believe, however, that the animal turn should be treated as a meta-turn: a process that requires a change in the relationship between the reflecting subject and the object of reflection, and not only as a specific kind of representation of the surrounding world. In the proposed text, I attempt to analyze the causes of the turn towards animals. I also address the theme of cognitive resistance in view of the recognition of animal studies as a fully-fledged theoretical and research area of contemporary humanities.

In 2018, more homes in the US have pets than those that have children. Though pets are regarded as property by US law, a majority of people identify pets as part of the family unit. Animal abuse and cruelty have been identified as a potential indicator and precursor to interpersonal violence (IPV). Moreover, child maltreatment, domestic violence, elder abuse, and animal abuse co-occur in households and communities link together to indicate the nexus of these heinous crimes; these co-occurring forms of violence have been increasingly referred to as The Link, to indicate the linked violence. However, there is an incongruence in the definition of animal abuse and cruelty; thus, documenting cases, bringing charges, and achieving a conviction is difficult. Furthermore, the initial education to learn of these topics in human service professions, such as social work, remains absent from many curricula. In practice, cross-reporting of suspected abuse or neglect is a vital mechanism for connecting human and animal professionals to address the issues between human and animal welfare systems. This sharing of information can increase the likelihood that clients experiencing IPV will receive comprehensive services that can improve their level of safety and quality of life. By providing professionals with education for indicators of abuse, and strategies for how to make a report, communities can build stronger support networks for those in need. Herein, Ohio legislation and current community efforts serve as a case study to define animal abuse, delineate transdisciplinary factors for relevance, and make recommendations for addressing this vital social welfare need. The strategies within this case-study are encouraged to be adapted and applied nationally and internationally.
Combating paraben pollution in surface waters with a variety of photocatalyzed systems: Looking for the most efficient technology

The constant presence of parabens in natural surface waters has raised a growing concern of the potential long-term toxic effects that parabens may have in wildlife, mainly as endocrine disruptors. The present report describes the results of a study in which different photocatalyzed systems, such as photo-Fenton, Fenton, UV-H2O2, UV-TiO2 and UV-TiO2-H2O2, were applied to the removal of these recalcitrant pollutants in some surface waters, including natural (e.g. rivers) and man-made (e.g. reservoirs and wastewater treatment plants). Degradation of four widely-used parabens (methyl-paraben, ethyl-paraben, propyl-paraben and butyl-paraben) was analyzed. Experimental results reveal that the most efficient method to combat these emerging pollutants was photo-Fenton. When this process was optimized, optimal removal efficiency was attained using doses of H2O2 and Fe(II) equal to 2.92·10−4 mol dm-3 and 1.85·10−5 mol dm-3, respectively. It is also worth noting that the removal rate of these contaminants is slower in natural waters. The results suggest that the photo-Fenton process is promising and maybe an adequate technology for the treatment of these persistent contaminants.

This pot experiment was to evaluate how salts (NaCl, Na2SO4) and alkali (Na2CO3+NaHCO3) affect the physiological and biochemical characteristics during the seedling stage of two cotton cultivars (salt-tolerant, L24; salt-sensitive, X45). Salt and alkali stress reduced seedling emergence rate, relative biomass, and chlorophyll content, however, the REC and MDA content increased. Salt and alkali stress increased markedly superoxide dismutase (SOD) activity. Peroxidase (POD) activity increased first and then decreased as the increase of salt and alkali stress. Catalase (CAT) activity initially increased and then decreased as NaCl stress increased. In addition, the SOD activity, REC, and MDA content was markedly higher in salt stress than that in alkali stress. The proline content of L24 was higher than that of X45 under salt and alkali stress. However, glycine betaine and soluble sugar content of L24 was lower than that of X45 under alkali stress. The REC and MDA content of L24 were lower than those of X45, however, the relative biomass, chlorophyll content, SOD, POD, CAT, and Pro were higher than those of X45. In conclusion, salt tolerant cotton cultivars may possess a superior protection effect by increasing antioxidant enzymes activity under salt and alkali stress.

This paper considers how creativity and creative activities can be encouraged in regular mathematical classes by combining different teaching approaches and academic disciplines. We combined origami and paper folding with fractals and their mathematical properties as well as with coding in Scratch in order to facilitate learning mathematics and computer science. We conducted a case study experiment in a Serbian school with 15 high school students and applied different strategies for learning profound mathematical and coding concepts such as fractals dimension and recursion. The goal of the study was to employ creative activities and examine students’ activities during this process in regular classrooms and during extracurricular activities. We used Scratch as a programming language, since it is simple enough for students and it focuses on the concept rather than on the content. Real-life situation of folding Dragon curve was used to highlight points that could cause difficulties in the coding process. Classroom observations and interviews revealed that different approaches guided students through their learning processes and gradually made the introduced concepts meaningful and applicable. With the introduction of this approach, students acquired understanding of the concept of coding recursion trough paper folding and applied it in the higher-level programming. In addition, our teaching approach made students enthusiastic, motivated and engaged with the learning of usually difficult subjects.

In order to clarify the dependence relationship between the heat storage & preservation wall and the thermal environment, and to provide data base and theory foundation for the north wall construction of the Chinese solar greenhouse (CSG), the experimental measures has been employed to investigate the distributions of temperature, humidity and heat transfer of three different wall materials (i.e. perforated brick, fine coal ash brick, common clay brick). The dynamic variations of the heat-storage and heat-release processes were identified, and the thermal response characteristics were discussed. The effect of north wall materials on the thermal environment of the solar greenhouse in northern China was revealed. The results indicated that the daily heat-storage and heat-release of fine coal ash brick wall can reach ϕimput
= 34.5~130.6 W·m−2 and ϕoutput
= −24.15~-45 W·m−2, respectively. The daily heat-storage time can reach t = 5~8 h, and the wall temperature at night can be 3~4
∘
C higher than the air temperature. Moreover, the maximum indoor temperature of the fine coal ash brick wall can be maintained at t ≤ 16.7 ≤ 31.1
∘
C, the minimum humidity can be maintained at 29.75~45%. Fortunately, the construction cost is moderate, while the physical properties are obviously better than those of perforated brick and common clay brick in the CSG. The overall thermal performance of fine coal ash brick is the best of the three north wall materials, and it can make the most advantage of the heat-storage and heat-preservation performances of the CSG. As a consequence, the fine coal ash brick wall of the solar greenhouse has good promotion value in northern China and other high latitude, high altitude and long winter regions.
