Authors: Ahmed Aya
Published: February 2020

This research aims at investigating the effectiveness of using Costa and Kallick's Habits of Mind in developing achievement and some visual thinking skills of first-year preparatory school pupils. To achieve that, the researcher designed the following: a list of Habits of Mind in the light of Costa and Kallick and converting it into educational goals which can be achieved after teaching geometry for the first year prep school pupils; Teacher's guide and pupils worksheets for teaching "geometry and measurement" unit of the first year prep school pupils according to Costa and Kallick's Habits of Mind; an achievement test of "geometry and measurement" unit for the second term of the first year prep school pupils and finally, visual thinking skills test. The current research used quasi-experimental research through applying it to a group of female pupils of the first year prep school. The sample consisted of (100) female pupils of Beni Ahmed prep school (1) in Minia Governorate, Egypt. It was divided into two groups: the experimental and control group. The control group consisted of (50) pupils taught with the traditional method, while the experimental group consisted of (50) pupils taught using Costa and Kallick's Habits of Mind. The results have shown that pupils' grades of the experimental group are higher than other group grades on achievement and some visual thinking skills. The researcher introduced some recommendations such as the necessity to set up professional development programs for training mathematics teachers in order to develop pupils' Habits of Mind, the necessity also to train student teachers of mathematics in the faculty of education to develop Habits of Mind. Moreover, Geometric content in the preparatory stage should be enriched with different educational activities that contribute to developing learners' visual thinking.

Authors: Sharov Sergey , Tolmachev Sergey
Published: February 2020

Introduction: The parameters chosen for complex coded signals used in active radar systems of aircraft for detecting objects largelydetermines their qualitative characteristics and the possibility of covert operation. An important task in the design of such on-boardsystems is the formation of ensembles of pseudorandom-noise binary code sequences of a fixed length with predefined characteristics.Purpose: Search for PRN binary code sequences of a given length, optimal by the criterion of the minimum level of the sidelobes of theaperiodic autocorrelation function. Results: A procedure of search for binary code sequences with specified parameters based on theevolutionary approach is proposed. The minimum level of positive sidelobes of the autocorrelation function is used as a criterion forthe selection of code sequences. An additional restriction is imposed on the length of a substring of codes of the same character. Thepossibility of forming a representative array of sequences with the best ratio of the main peak of the aperiodic autocorrelation functionto its maximum positive sidelobe is shown on the example of 31-bit code sequences. An algorithm is proposed for generating a PRNseries of signals using the code sequences found. The Hamming distance is used as a measure of the difference between two binary codesequences in the series. The proposed approach is advantageous as compared to the well-known method of generating PRN signals basedon pseudorandom m-sequences. Practical relevance: The results obtained can be used in algorithms of airborne radar systems with ahigh range resolution to detect physical objects on the background of an underlying surface, for example, objects on the water surface.

Published: February 2020

Background: Effective analgesia is important after laparoscopic cholecystectomy. Paracetamol have been used extensively as alternatives, and it seems that they are more effective for mild to moderate pain control postoperatively. As laparoscopic Cholecystectomy poses moderate pain, in this study we compare the quality of analgesia and side effects of paracetamol versus pethidine for post-operative analgesia after laparoscopic cholecystectomy.

Objectives: This study was designed to observe the effect of I.V. paracetamol and I.M. pethidine for analgesic efficacy in post-operative analgesia with their side effects in laparoscopic cholecystectomy. Material and method: Sixty (60) patients were selected in the pre anaesthetic check up room whose were going to be operated for laparoscopic cholecystectomy. Each patient in group A received intravenous paracetamol (1g/100ml)15mg/kg over 15minutes and group B received intramuscular pethidine (100mg)- 2mg/kg postoperatively.

Results: In group A that was paracetamol group and group B that was pethidine group the visual analogue scale (VAS) almost similar but total analgesic consumption in pethidine group were slightly higher than paracetamol group and the respiratory rate were significantly lower in pethidine group.

Conclusion: Our results indicate that IV paracetamol 15mg / kg has better analgesic potency and less side effects than 2 mg / kg IM pethidine for postoperative analgesia after laparoscopic cholecystectomy.

Global biogeography of marine amphipod crustaceans: latitude, regionalization, and beta diversity
Authors: Arfianti T , Costello MJ
Published: February 2020

Studying the biogeography of amphipod crustaceans is of interest because they play an important role at lower trophic levels in ecosystems. Because they lack a planktonic larval stage, it has been hypothesized that marine benthic amphipod crustaceans may have short dispersal distances, high endemicity, and spatial turnover in species composition, and consequently high global species richness. In this study, we examined over 400000 distribution records of 4876 amphipod species, and identified 12 regions of endemicity. The number and percent of endemic species peaked at 30°-35°S and coincided with 3 of these regions of high endemicity: Australia, New Zealand, and southern Africa. Pelagic species of marine amphipod crustaceans were more cosmopolitan than benthic species. The latitudinal patterns of richness (alpha, gamma, and ES50) and species turnover were at least bimodal. Most occurrence records and greater alpha and gamma richness were in mid-latitudes, reflecting sampling bias. Both ES50 and beta diversity had similar richness in the tropics, mid-latitudes, and on the Antarctic shelf around 70°S. These 2 indices exhibited a sharp dip in the deep Southern Ocean at 55°S. ES50 peaked at 30°-35°S and a small dip was apparent near the equator at 5°-10°N. Beta diversity was driven mostly by turnover rather than nestedness. These findings support the need for conservation in each realm of species endemicity—and for amphipods, particularly in Antarctica and the coastal mid-latitudes (30°-35°S) of the Southern Hemisphere.

A hemodynamic feature of chronic sinoaortic-denervated (SAD) rats is the increase in blood pressure variability (BPV) without significant changes in the average level of blood pressure (BP). The current study was designed to investigate the changes in BP V-shaped waves (V waves) in SAD rats. Sprague-Dawley (SD) rats were divided into 2 groups: SAD rats and sham-operated rats (n=13). Hemodynamics measurements were obtained in conscious, freely moving rats, four weeks after sinoaortic denervation or sham operation. V wave indices were evaluated in rats in both conscious and quiet states. Additionally, normal and high BPV was simulated by the production of V waves with different amplitudes. The results showed that the V wave amplitude was dramatically increased, with a significantly prolonged duration and reduced frequency in SAD rats. V wave BPV in SAD rats was significantly increased, though BP remained unchanged. The twenty-four hour BPV in all rats was positively correlated with amplitude, duration time and V wave BPV and negatively correlated with frequency. The systolic BP spectral powers in the low frequency range (0.38-0.45 Hz) were significantly reduced in the V waves of SAD rats. Moreover, there was a remarkable increase in mean BPV and a normal mean BP after simulating high BPV in SAD rats. These results suggest that enhancement of V waves might be a waveform character of BP in SAD rats in both the conscious and quiet states. These types of V waves appear to be related to a depression of sympathetic regulation of BP induced by sinoaortic denervation.

Aquaporin proteins (AQPs) are a family of channels expressed in numerous mammalian tissues, where they play a fundamental role in regulating water transport across cell membranes. Based on reports that AQPs are present in the reproductive system and participate in reproductive processes, our aim was to investigate the effect of progesterone (P4), estradiol (E2), oxytocin (OT), arachidonic acid (AA), forskolin (FSK) and cyclic adenosine monophosphate (cAMP) on AQP1 and AQP5 expression at mRNA and protein levels in porcine uterine explants from Days 14-16 of gestation in order to determine if they play a role in implantation period in pigs. Quantitative real time PCR and Western-blot analysis revealed that the uterine explants treated with FSK and cAMP produce delayed, but long-term effects on AQP1 abundance (24 h) while AQP5 had a rapid and sustained response to FSK and cAMP in protein content (3 and 24 h). AA increases gene and protein content of AQP1 after longer exposition whereas AQP5 increases after 3 h only at the protein level. Both AQPs potentially remains under control of steroid hormones. OT has been shown to increase AQP1, and decrease AQP5 mRNA, without visible changes in protein content. P4, E2, AA, FSK and cAMP caused the appearance of AQP5 expression in the basolateral plasma membrane of the epithelial cells. The staining represents most likely AQP5 functioning mechanism for both absorption and reabsorption across the glandular epithelium.

Published: February 2020

A negative emotional state resulting from the withdrawal of drug addiction is thought to be an important factor that triggers and exacerbates relapse. Since the insular cortex is a key brain structure involved in the modulation of negative emotions, we investigated whether the integrity of the insular cortex was important for motivational aversion associated with morphine withdrawal as well as whether this kind of negative emotion induced neuroadaptation in the insular cortex. In this present study, a sensitive mouse conditioned place aversion (CPA) model measuring the motivational aversion of morphine withdrawal was first established. Our results showed that bilateral insular cortex lesions by kainic acid completely inhibited the expression of CPA. The expression of FosB/ΔFosB in the insular cortex was significantly increased 24 h after the CPA regime was performed, but the expression of c-Fos in the insular cortex did not changed. These findings indicate that the integrity of the insular cortex is essential to motivational aversion associated with morphine withdrawal, and that this kind of aversion induces neuroadaptation, observed as the increase of FosB/ΔFosB expression, in the insular cortex.

During the process of intra-uterine mammalian fetal development, the oxygen supply in growing fetus is low. A rapid switch from glycolysis-based metabolism to oxidative phosphorylation (OXPHOS) must proceed during early postnatal adaptation to extra-uterine conditions. Mitochondrial biogenesis and mammalian mitochondrial FOF1-ATP synthase assembly (complex V, EC 3.6.3.14, ATPase) are complex processes regulated by multiple transcription regulators and assembly factors. Using RNA expression analysis of rat liver and skeletal tissue (Rattus norvegicus, Berkenhout, 1769), we describe the expression profiles of 20 genes involved in mitochondrial maturation and ATP synthase biogenesis in detail between the 16th and 22nd day of gestation and the first 4 days of life. We observed that the most important expression shift occurred in the liver between the 20th and 22nd day of gestation, indicating that the fetus prepares for birth about two days before parturition. The detailed mechanism regulating the perinatal adaptation process is not yet known. Deeper insights in perinatal physiological development will help to assess mitochondrial dysfunction in the broader context of cell metabolism in preterm newborns or neonates with poor adaptation to extra-uterine life.
Cavity dumping by the second harmonic generation in the Q-switched Nd : YAG laser

Published: February 2020

This paper presents the cavity dumping method by the second harmonic generation in a neodymium laser operating in the Q-switched mode. Theoretical modeling of the laser generation in dynamics is performed. The main characteristics of the output pulses and their dependence on the pump power and coefficient of losses are calculated. The proposed method can be implemented in the laser with a second harmonic crystal inside the cavity and an electro-optical crystal, which is operated by a step voltage pulse. The switching pulse length is defined by the time needed to achieve the maximum giant pulse intensity in the cavity, and is in the order of 0.1–1.0 ms depending on the pump power. Moreover, the voltage pulse jitter should not exceed several nanoseconds. In such case the second harmonic pulses with nanosecond duration and peak intensity of 10 –100 MW/cm2 are generated at the laser output. The output pulses duration is defined only by the cavity length under the conditions of a small response time of the electro-optical crystal compared to the cavity round-trip time. To achieve the maximal peak intensity, one should decrease the coefficient of inactive losses to the possible minimum and increase the pump power.

Published: February 2020

Microstructure of rapidly solidified eutectic alloy foil Sn – 8.8 wt. % Zn was studied. The alloy foil consists of solid solutions of zinc and tin. Dark equiaxed dispersed precipitates of zinc solid solution are uniformly interspersed in the matrix of tin solid solution. The parameters of the microstructure were determined. The average chord of a random secant at the sections of precipitates of a solid solution of zinc is 0.33 mm, and the specific interface surface is 0.81 mm–1. The precipitations of the tin solid solution have a microcrystalline structure. Specific surface of high angle boundaries less than 1 mm–1. The texture of the precipitates of solid solutions of tin and zinc in the foil was studied, and the pole densities of the diffraction lines of these phases are presented. The tin solid solution has the texture (100), and the zinc solid solution has the (0001) texture, which is explained by the predominant growth of grains, in which the crystalline planes of (100) tin and (0001) zinc are most closely packed and perpendicular to the heat flux. Eutectic alloy Sn – 8.8 wt. % Zn is in an unstable state. Annealing the foil causes the dissolution of small and coarsening of large particles of zinc solid solution, as well as the decomposition of a supersaturated tin solid solution. These processes cause an enlargement of the microstructure: an increase in the average particle size (dZn) of a solid solution of zinc and its volume fraction (VZn), a decrease in the specific surface (S ) of interphase boundaries.

Published: February 2020

Perkembangan Internet dan aplikasi berbasis jaringan telah menjangkau ke berbagai macam aplikasi yang memungkinkan seseorang untuk saling berkirim pesan dan informasi tanpa dibatasi jarak dan waktu. Seiring dengan perkembangan itu pula, kerentanan akan aspek keamanan sebuah system juga semakin meningkat. Dalam penelitian ini, peneliti mencoba menerapkan kombinasi antara metode kriptografi dan steganografi yang bertujuan untuk meningkatkan upaya pengamanan sebuah pesan. Kriptografi Cipher Block Chaining (CBC) merupakan kriptografi yang sudah umum digunakan contohnya pada protocol internet TLS dan IPsec. Proses enkripsi dan dekripsi CBC memerlukan waktu yang relatif singkat karena mode CBC memiliki kecepatan dan efisiensi lebih tinggi dan dinilai lebih mudah diimplementasikan. Metode berikutnya yang digunakan adalah Steganografi Least Significant Bit (LSB) yang bekerja secara sederhana namun sangat efektif dalam menyisipkan pesan tersembunyi. Namun, beberapa penelitian menemukan kelemahan LSB yang dapat menemukan keberadaan pesan tersembunyi menggunakan algoritma steganalytic pada tingkat embedding yang rendah. Untuk itu, LSB harus dikembangkan lagi dengan menerapkan deteksi tepi sobel yang dapat bekerja untuk mendeteksi keypoint penyembunyian pesan sehingga LSB tidak lagi bekerja secara standar. Kombinasi metode CBC dan LSB-Sobel telah terbukti dan berhasil merahasiakan pesan dengan baik dan menghasilkan stego-image yang berkualitas tinggi setelah dilakukan pengujian PSNR dan MSE. Kata kunci: Kriptografi, steganografi, CBC, LSB, Deteksi Tepi Sobel

Inovasi menggunakan gamifikasi diperlukan untuk menghadapi persaingan antar e-commerce. Gamifikasi berguna untuk meningkatkan pengalaman, menjaga kesetiaan pelanggan, penguatan merk dan melengkapi motivasi pembeli dan melakukan transaksi di e-commerce. Bentuk yang umum dari gamifikasi adalah pemberian reward bagi pelanggan dengan kondisi tertentu. Kondisi ini contohnya adalah lama menjadi pelanggan, besar transaksi, jenis transaksi. Masalah yang terjadi berkaitan dengan pemberian reward kepada pelanggan adalah reward yang tidak sesuai dan monoton atau mudah ditebak sehingga unsur kejutan yang menjadi salah satu elemen penting dari reward menjadi menurun kualitasnya. Penelitian ini bertujuan membentuk model gamifikasi yang tidak monoton menggunakan kecerdasan buatan dengan metode logika fuzzy. Logika fuzzy mampu membentuk perilaku reward yang dinamis sehingga meningkatkan kualitas reward yang diberikan kepada pelanggan. Input yang digunakan untuk menentukan reward adalah banyaknya transaksi, banyak produk dipilih dan total biaya pesanan.

« Dans un pleur assidu »: champs lexicaux de l'émotion dans la poésie de Marceline Desbordes-Valmore
Authors: Assa Sonia
Published: February 2020

Desbordes-Valmore sut créer, pour dire l'émotion, l'un des lexiques les plus sensuels de la poésie romantique française. Grâce à ce lexique, le monde des sentiments s'ouvre sur celui des sensations physiques. Dans son univers poétique, certains mots s'appellent, formant des chaînes sémantiques où l'on entend l'inflexion unique de sa personnalité. Je montrerai comment le sujet poétique féminin qu'elle construit exprime et communique l'émotion en se servant de trois grands motifs: le frémissement, l'abandon et l'essor, chacun pourvu d'un lexique éminemment personnel et sensuel. À travers ces combinaisons lexicales qui lui sont propres, elle « dit » la passion avec originalité, et donne une voix au désir et au plaisir féminins. Malgré l'imprécision, le flou et même la pauvreté de son vocabulaire, malgré l'ubiquité des mots « âme », « fleurs », « ange » et « cœur », c'est du corps qu'elle parle, sans le nommer directement.

It explores Schérer's scepticism regarding children's ‘emancipation’ in the post-68 period and his attacks on developmental expertise derived from the fields of psychology, psychoanalysis and pedagogy. Existing critical appraisals of this body of work have focused, unsurprisingly, on its apology for paedophilia, which Schérer promoted as a means of liberating children from society's dominant maturational narratives. The article rejects Schérer's defence of paedophilia. It argues, however, that the philosopher's controversial views on intergenerational desire conceal a number of other ethical and epistemological concerns that merit revisiting. These arise from Schérer's reflections on generational distinction, the temporalities of childhood and adulthood and the ethics of representation.

Combination regimens have shown superiority over single agents in the adjuvant treatment of resected pancreatic cancer (PC), but there are no data supporting definition of the best regimen. This work aimed to compare the efficacy and safety of mFOLFIRINOX, gemcitabine+capecitabine, and gemcitabine+nab/paclitaxel in PC patients. A meta-analysis was performed for direct comparison between trials comparing combination regimens and gemcitabine monotherapy. Subsequently, an indirect comparison was made between trials investigating the efficacy and safety of mFOLFIRINOX, gemcitabine+capecitabine, and gemcitabine+nab/paclitaxel because of the same control arm (gemcitabine). A total of three studies met the selection criteria and were included in our indirect comparison. Indirect comparisons for efficacy outcomes showed a benefit in terms of DFS (disease-free survival)/EFS (event-free survival)/RFS (relapse-free survival) for both mFOLFIRINOX versus gemcitabine+capecitabine (HR 0.69, 95% CI 0.52–0.91) and versus gemcitabine+nab/paclitaxel (HR 0.67, 95% CI 0.50–0.90). No significant advantage was registered for OS (overall survival). Indirect comparisons for safety showed an increase in terms of G3-5 AEs (with the exception of neutropenia) for mFOLFIRINOX versus gemcitabine+capecitabine (RR 1.24, 95% CI 1.03–1.50), while no significant differences were observed versus gemcitabine+nab/paclitaxel. According to our results, mFOLFIRINOX is feasible and manageable and could represent a first option for fit PC resected patients.

The impacts of climate change are not equally distributed globally. We examined the global distribution of CO2 emissions and the ensuing distribution of increases in the risk of zinc and protein deficiency resulting from elevated atmospheric CO2 concentrations. We estimated cumulative per capita (2011–2050) CO2 emissions for 146 countries using existing measurement data and by apportioning regional emissions projections. We tested the relationship between cumulative per capita CO2 emissions and the risk of additional zinc and protein deficiency at the population-level and country-level. At the population-level (i.e., population-weighted), we observed a significant inverse association between CO2 emissions and the percentage of the population placed at additional risk of zinc (p-value: <0.001) and protein (p-value: <0.01) deficiencies. Country-level (i.e., unweighted) analyses produced significant but less strong associations. Populations with lower per capita CO2 emissions between 2011 and 2050 will experience a disproportionately high nutritional burden, highlighting socioeconomic, geospatial, and intergenerational injustices.

In this work, a lettuce-like ZnO gas sensor with high sensitivity for H2S detection was successfully fabricated by a one-step hydrothermal method. Characterization analysis of the phases, crystallinities, morphology, and chemical compositions indicated that lettuce-like ZnO has a lettuce-like microsphere structure composed of wurtzite hexagonal ZnO sheets. A gas sensitivity test of the lettuce-like ZnO showed that the sensor had a high H2S response (113.04 for 100 ppm H2S) and H2S selectivity. The lettuce-like ZnO sensor has fast response characteristics while maintaining high sensitivity, and has a response time as low as 15 seconds and a recovery time of 90 seconds, and the detection limit reaches 1 ppm. The sensitive mechanism of lettuce-like ZnO sensor to H2S is also discussed.

Loess-paleosol series are well preserved in the south part of the Russian Plain. However, these sequences have a low number of studies on their organic matter, such as researches of isotope composition, n-alkane and other biomarkers. Thus, the purpose of the study was to reconstruct vegetation conditions from the Late Glacial to Late Holocene. We used the leaf wax-derived n-alkanes to detect vegetation evolution of the Bryansk Region. The stable carbon isotope composition of organic matter and pedogenic carbonates was carried out for the same aim. Three paleosols (of Lasko, Bølling-Allerød warmings and Holocene second humus horizons) and modern soils of different relief positions were investigated. n-Alkane distribution, as well as isotope composition indicates changes from grassy to woody vegetation during this period. The use of biomarkers such as n-alkanes helps to more clearly interpret isotopic data.
Biosorption Characteristics of Hg(II) from Aqueous Solution by the Biopolymer from Waste Activated Sludge

The divalent mercury ion (Hg(II)) is one of the most hazardous toxic heavy-metal ions, and an important industrial material as well. It is essential to remove and recover Hg(II) from wastewater before it is released into the environment. In this study, the biosorption characteristics of Hg(II) from aqueous solution by the biopolymer from waste activated sludge (WAS) are investigated. The major components of the biopolymer consisted of proteins, carbohydrates, and nucleic acids. The adsorption kinetics fit for the pseudo-second-order kinetic model, and the adsorption isotherms were well described by Langmuir equation. The adsorption capacity of the biopolymer increased along with rising temperature, and the maximal adsorption capacity was up to 477.0 mg Hg(II)/g biopolymer at 308 K. The infrared spectroscopy analyses showed that the complexation of Hg(II) by the biopolymer was achieved by the functional groups in the biopolymer, including hydroxyl (–OH), amino (–NH2), and carboxylic (–COOH). From the surface morphology, the special reticulate structure enabled the biopolymer to easily capture the metal ions. From the elemental components analyses, a part of Hg(II) ions was removed due to ion exchange with the Na+, K+, and Ca2+, in the biopolymer. Both complexation and ion exchange played key roles in the adsorption of Hg(II) by the biopolymer. These results are of major significance for removal and recovery of Hg(II) from wastewater.

After the recession in Japan in the 1990s, Japanese art exhibitions began to appear. The purpose of these exhibitions was to revitalize these areas through the presentation of art (attracting visitors and tourists). Correspondingly, this study explores the significance of exhibition-driven tourism in Japan. The Echigo–Tsumari Art Triennial (ETAT) was used as a case to study how exhibition-driven tourism has impacted sustainable tourism, economics, and the population. The current paper collected panel data from 1900 to 2018. These panel data were analyzed by descriptive statistics and a correlation analysis (a one-way ANOVA and a Pearson correlation analysis in SPSS26). The empirical analysis showed that the Echigo–Tsumari Art Triennial (exhibition-driven tourism) had positive impacts on sustainable tourism, economics, and the population; its correlations with Niigata were also clear. This study generated results that are valuable from both academic and industry perspectives (exhibition-driven tourism), as this field has not been extensively researched. The current paper also presents the theoretical and practical implications of the statistical results.

The Work-Related Quality of Life Scale (WRQLS) was developed by Van Laar et al. The Thai version was developed and could be completed in 13.4 min on average with some items having a factor loading of less than 0.4. The aims of this study were (a) to develop a brief Thai version of the WRQLS (brief THWRQLS), and (b) to assess its validity and reliability. A descriptive correlation study was performed with the components of THWRQLS selected based on statistical and judgmental criteria. The statistical criteria were developed using secondary data from 320 physicians identifying discrimination, internal consistency and exploratory factor analysis (EFA). The judgmental criteria included content validity and agreement by five experts. The web-based brief THWRQLS was then used by 250 health personnel, and confirmatory factor analysis (CFA) was conducted and internal consistency assessed. The brief THWRQLS consisted of seven dimensions, encompassing 25 of the original 32 items. The CFA revealed that most of the standardized factor loadings were greater than 0.5. The χ2goodness of fit was 268.772 (p < 0.01), the comparative fit index was 0.971, the root mean square error of approximation was 0.039, and the standardized root mean square residual was 0.049. The Cronbach’s alpha coefficient of the scale was 0.94, and almost all dimensions were greater than 0.7 except for that of “stress at work,” which was 0.53. In conclusion, the brief THWRQLS appeared to be valid, and the reliability was acceptable, except in the dimension of “stress at work.”
