An update of a simulation study of passively heated residemtial buildings

A simulation study of passively heated residential buildings” published in Procedia Engineering 2015 showed how circulating 15-17ºC water from a 50-m deep U-tube to a floor radiator and solar-heated water from a 30 evacuated tube solar collector and a 2-m3 indoor tank to a wall radiator could keep a 30-m2 Melbourne, Australia house thermally comfortable. This paper presents a summary of the ongoing review of publications together with three updates: - (1) Report on that water heated by a 100-metre deep U-tube is 22-24ºC, i.e., 2-4 ºC warmer than thermal comfort temperature. (2) May 2016 experimental validations of the simulated results which show that when the outdoors is below 10ºC, the temperature of the floor radiator is 2-4ºC less than the 15-17ºC water heated by a 50-m deep U-tube and 25 W fish tank pumps could circulate the waters. (3) Simulations with the addition of phase change materials (PCM) to inside faces show that though a PCM halves the diurnal indoor temperature variations, it confirms that such PCM does not significantly increase the 20ºC temperature in a 2-m3 storage tank at the end of winter. Therefore, the size of intersessional thermal storage would be a problem for family-sized houses. German Guidelines indicate that 1-2 boreholes could provide enough heat for family-sized houses. The heat extracted in winter can be replenished in summer. Thus the geothermal heat from about 100-m deep boreholes with 22-24ºC bottom temperature could sustainably keep residential buildings in cool climates similar to Melbourne's cool temperate thermally comfortable

State transfer based on classical nonseparability

We present a state transfer protocol that is mathematically equivalent to quantum teleportation, but uses classical nonseparability instead of quantum entanglement. In our implementation we take advantage of nonseparability among three parties: orbital angular momentum (OAM), polarization, and the radial degrees of freedom of a beam of light. We demonstrate the transfer of arbitrary OAM states, in the subspace spanned by any two OAM states, to the polarization of the same beam

Wigner distribution of twisted photons

We present the first experimental characterization of the azimuthal Wigner distribution of a photon. Our protocol fully characterizes the transverse structure of a photon in conjugate bases of orbital angular momentum (OAM) and azimuthal angle (ANG). We provide a test of our protocol by characterizing pure superpositions and incoherent mixtures of OAM modes in a seven-dimensional space. The time required for performing measurements in our scheme scales only linearly with the dimension size of the state under investigation. This time scaling makes our technique suitable for quantum information applications involving a large number of OAM states

Production of bioethanol and enzyme activities by a white-rot fungus on lignocelluloses under variant cultivation atmospheres

In this research, lignocellulose decomposition and bioethanol production potentiality of the white rot fungus Phlebia radiata 79 was studied at different atmospheric conditions on several solid substrate mixtures containing spent brewery barley mash (SBBM), barley straw, spruce wood sawdust, and birch wood sawdust. The fungus was capable of growing on all substrate mixtures, subsequently converting them into fermentable sugars like glucose, producing various primary metabolites involving ethanol, acetate, and glycerol. Ethanol accumulation was always dominant under nitrogen flushed anaerobic conditions as well as semi-aerobic conditions. The highest concentration of ethanol accumulated on the second week of cultivation on all solid substrate mixtures. Under anaerobic conditions, the detected amount of ethanol was 88 mmol/l, 87 mmol/l, and 108 mmol/l, after two weeks of cultivation of the fungus on lignocellulose substrates containing SBBM mixed with barley straw, spruce wood sawdust, or birch wood sawdust, respectively. Under semi-aerobic conditions, corresponding concentrations of ethanol - 90 mmol/l, 61 mmol/l, and 105 mmol/l - accumulated in the cultures after two weeks of cultivation on the same substrate mixtures, respectively. Under aerobic conditions, only small amounts of ethanol were detected during the first two weeks of cultivation. Another part of the study was to establish an enzyme assay method for pectin degradation and conversion, in order to measure the activities of specific carbohydrate-active enzymes (CAZymes) involving pectinase, as well as cellulolytic β-glucosidase and cellobiohydrolase (CBH) activities. The highest β-glucosidase activity (5.2 nkat/ml) was observed under aerobic conditions in cultures on the substrate mixture of SBBM and barley straw. CBH activity was also prominent under aerobic conditions, and the maximal activity (0.7 nkat/ml) was detected on the substrate mixture of SBBM and spruce wood sawdust, while elevated pectinase activity (83 nkat/ml) was recorded under aerobic conditions on substrate mixtures containing SBBM and barley straw. Thus, the conclusions are that composition of the solid waste lignocellulose substrate mixture affected enzyme production by the fungus, whereas production of ethanol was mainly controlled by the cultivation atmosphere. Interestingly, both anaerobic and semi-aerobic atmospheric conditions supported similar bioconversion efficiency resulting with similar high levels of bioethanol production in the fungal cultures within two weeks

The effectiveness of Guided-Discovery Strategy Supported by the Technology of Augmented Reality on Acquiring Mathematical Concepts for Grade Four Male Students in Jordan.

This research aimed to know the effectiveness of guided discovery supported by augmented reality technology in acquiring mathematical concepts among fourth-grade students in Jordan. The quasi-experimental approach was adobted. To achieve the goal of this research, a teacher’s guide and a mathematical concepts test were developed. The validity and reliability of instruments were confirmed. The research members consist of (40) students in the first semester of 2020/2021, They were distributed equally into two groups: the experimental group studied using the suggested strategy and the control group studied using the usual way .The results showed that there were statistically significant difference at the level of significance (α = 0.05) in the acquisition of mathematical concepts in favor of the experimental group. The research recommended generalizing the experience to different subjects and conducting other new studies on different classes and variables

A Semi-Automatically Assessable Design for a Hands-On Compilers Course

This paper describes the author's experience with ahands-on compilers course designed and carried on in theGerman University in Cairo. The five main points are the courseobjectives, the course organization, the author's approach toformulating the lab exercises – an approach recommended forprogramming courses in general (which is also the maincontribution as it offers a method for “semi-automatic” gradingwithout the need for an automatic assessment system, besidesdocumenting the author's experience categorizing and offering ahands-on compilers course), the small language “invented” forwhich the lexical analyzer, syntactic analyzer and interpreter areto be written by the students (which is the course's ongoingproject) and the adopted grading scheme. Besides, having thecourse’s project seamlessly integrated within the other exercises(as opposed to a separate bulk at the end of the course) is anotherpoint stressed in its design. An idea for a system for automatingthe whole process is proposed at the end

Effect of Perampanel or Amantadine Treatment on Pilocarpine Rat Model of Status Epilepticus: Evidence with Seizure Termination, Behavioral Alterations, Epileptogenesis and Neuronal Damage.

Persistent activation of ionotropic glutamatergic receptors contributes to seizure sustenance and neuronal cell death. Status epilepticus (SE) was induced in adult male Sprague Dawley [12 to 14 weeks old] rats by treating them with pilocarpine. The efficacy of either perampanel, an α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor blocker, or amantadine, a N-Methyl-D-aspartic acid (NMDA) receptor blocker, in overcoming pilocrapine-induced SE was assessed using electroencephalogram (EEG) recordings. In addition, the alterations in cognitive function, development of spontaneous recurrent seizures (SRSs), and hippocampal damage that are generally encountered in SE were also assessed at 72 hours and 1 month after pilocarpine treatment. Our results show that both early and late treatment with perampanel but not amantadine significantly reduced the latency in the termination of seizure as confirmed by EEG recording. Perampanel but not amantadine, reversed the memory impairment in SE rats and retarded the appearance of SRS. Fluoro-Jade C staining and NeuN immunohistochemistry revealed the protective effects of perampanel. Perampanel treatment led to reduced caspase-3 activation in the hippocampal sections of brains isolated from SE rats. In vitro addition of either perampanel or amantadine in primary cultures of hippocampal neurons significantly reduced the levels of cytotoxicity and caspase-3 activation induced by AMPA and NMDA. Both perampanel and amantadine treatment also reduced GAPDH, p53, PTEN, and active SREBP-1 levels expressed in nuclear fractions isolated from the primary cultures of hippocampal neurons treated with either AMPA or NMDA. Our data might shed some light in the therapeutic approach of perampanel in clinical use for status epilepticu
