Published: August 2020

Abstract. River ice, like open-water conditions, is an integral component of the cold-climate hydrological cycle. The annual succession of river ice formation,
growth, decay and clearance can include low flows and ice jams, as well as
midwinter and spring break-up events. Reports and associated data of river
ice occurrence are often limited to single locations or regional
assessments, are season-specific, and use readily available data. Within
Canada, the National Hydrometric Program (NHP) operates a network of gauging
stations with water level as the primary measured variable to derive
discharge. In the late 1990s, the Water Science and Technology Directorate
of Environment and Climate Change Canada initiated a long-term effort to
compile, archive and extract river-ice-related information from NHP
hydrometric records. This data article describes the original research data
set produced by this near 20-year effort: the Canadian River Ice Database
(CRID). The CRID holds almost 73 000 recorded variables from a subset of 196
NHP stations throughout Canada that were in operation within the period 1894
to 2015. Over 100 000 paper and digital files were reviewed, representing
10 378 station years of active operation. The task of compiling this
database involved manual extraction and input of more than 460 000 data
entries on water level, discharge, ice thickness, date, time and data
quality rating. Guidelines on the data extraction, rating procedure and
challenges are provided. At each location, time series of up to 15 variables
specific to the occurrence of freeze-up and winter-low events, midwinter
break-up, ice thickness, spring break-up, and maximum open-water level were
compiled. This database follows up on several earlier efforts to compile
information on river ice, which are summarized herein, and expands the scope
and detail for use in Canadian river ice research and applications.
Following the Government of Canada Open Data initiative, this original river
ice data set is available at

Effectiveness of Large-Scale Social Restrictions (PSBB) toward the New Normal Era during COVID-19 Outbreak: a Mini Policy Review
Authors: Andriani, S.Si, Apt, M.Sc, Ph.D Helen 
Published: August 2020

Abstract. The government of Indonesia has not used lockdown or quarantine as an option to tackle the spread of Coronavirus, as the impact of lockdown on small communities in the informal sector that lives from daily income will be severe. Alternatively, the government is enforcing Large-Scale Social Restrictions (Pembatasan Sosial Berskala Besar or "PSBB") to respond to the state of emergency in public health. Starting in June 2020, the government has implemented transitional PSBB in some red zone areas, including the capital Jakarta and East Java province, despite the surge in case numbers. This paper aims to investigate the effectiveness of the PSBB policy applied in Indonesia during the COVID-19 outbreak and the readiness to embrace the new normal, between April and June 2020, based on rapid literature analysis in a search on Medline(-Pubmed), government speeches and reports, social and mass media platforms. Implementation of PSBB is a preventive measure to combat Coronavirus’ spread in some Indonesian areas. Indonesia should not be in a “new normal” situation. The transitional PSBB phase serves as an early chapter of a new normal that would apply only to strategic sectors with manageable risks combined with better regulation and compliance by the public. Abstrak. Pemerintah Indonesia tidak menggunakan lockdown atau karantina sebagai opsi untuk mengatasi penyebaran Coronavirus, karena dampak lockdown pada komunitas kecil di sektor informal yang hidup dari pendapatan harian akan memburuk. Pemerintah menegakkan Pembatasan Sosial Berskala Besar (PSBB) sebagai respons terhadap keadaan darurat dalam kesehatan masyarakat. Sejak bulan Juni 2020, pemerintah telah menerapkan transisi PSBB di beberapa daerah zona merah, termasuk di provinsi DKI Jakarta dan Jawa Timur, meskipun ada peningkatan jumlah kasus. Artikel ini bertujuan untuk menyelidiki efektivitas kebijakan PSBB yang diterapkan di Indonesia selama wabah COVID-19 dan kesiapan untuk memasuki Adaptasi Kebiasaan Baru (AKB), antara bulan April dan Juni 2020, berdasarkan analisis literatur cepat dalam pencarian Medline (-Pubmed), pidato dan laporan pemerintah, platform media sosial dan media massa. Implementasi PSBB adalah langkah pencegahan untuk memerangi penyebaran Coronavirus di beberapa wilayah Indonesia. Indonesia seharusnya tidak berada dalam situasi AKB. Fase PSBB transisi berfungsi sebagai bab awal dari AKB yang hanya akan berlaku pada sektor strategis dengan risiko yang dapat dikelola bersamaan dengan regulasi dan kepatuhan public yang lebih baik.

Aims: To analyze the chemical constituents of ethyl acetate extract from MSR-1707 to promote the rational utilization of the mushroom resources.
Methodology: MSR-1707 belongs to the genus Nigrospora sp. It was extracted by ethyl acetate, then the extract was analyzed by Gas Chromatography-Mass Spectrometer (GC-MS). Identification of compounds was achieved according to their GC retention indices (RI) and database search using the library of NIST05, as well as a comparison of the fragmentation pattern of the mass spectra with data published in the literature.
Results: Seventy-three compounds were separated by gas chromatography. Based on the NIST05 spectral library and corresponding literature information, fifty-three compounds were identified. Their relative percentage of contents accounted for 95.62% of the outflow peak. Some of the identified peaks are 9-Octadecenoic acid, methyl ester(E)(18.50%),9-Tricosene(Z)(8.30%), 13-Docosenamide (E)(5.26%) and Myristic acid glycidyl ester (3.11%).
Conclusion: This is the first report of chemical constituents of the ethyl acetate extract of Nigrospora sp. using GC-MS, which offer some theoretical basis for the further exploration and application of this mushroom.
A Two-part Approach to the Determination of Intrinsic Rate Constants of an Alpha-amylase Catalysed Reaction
Authors: Udema Ikechukwu I. 
Published: August 2020

Background: There is a need for equations with which to calculate the intrinsic rate constants that can further characterise enzyme catalysed reactions despite what seems to be conventional differences in methodology in the literature.
Methods: Theoretical, experimental (Bernfeld method), and computational methods.
Objectives: 1) To derive an alternative intrinsic rate constant equations consistent with their dimension, 2) derive electrostatic intermolecular potential energy equation, (xe), 3) calculate the intrinsic rate constants for forward (k1) and reverse (k2) reactions, and 4) define the dependence or otherwise of kinetic constants on diffusion and deduce the catalytic efficiency.
Results and Discussion: The ultimate quantitative results were ~ 64.69 ± 0.49 exp (+3)/ min (k2) (and kd (s) = ~ 60.66 exp (+3)/ min), ~ 1594.48 ± 11.99 exp (+3) exp (+3) L/mol.min (k1) (and ka (s) = ~1482.47 exp (+3) L/mol.min), ~ 58.00 ± 10.83 exp (+3) /min, the apparent rate constant for reverse reaction (kb), and ~ 75.83 ± 10.83 exp (+3) /min, the rate constant for product formation (k3). The catalytic efficiency was: 3.025 exp (+ 9) L / mol.
Conclusion: The relevant equations were derived. Based on the derived equations the intrinsic rate constants can be calculated. Since k3 is > kb, then k3 is diffusion controlled and it appears that the enzyme has reached kinetic perfection. The evaluation of rate constants either from the perspective of diffusion dependency or independency cannot be valid without Avogadro number.

A study was conducted in mid hill region of Rajouri district, J&K, India to analyze the impact lockdown amid covid-19 pandemic on weather parameters. Day and night temperature readings were recorded fortnightly from 1st March to 30th June 2020 from maximum and minimum thermometer, rainfall values from ordinary rain gauge, and soil temperature at different depth from soil thermometers and values were compared with data from 2017-2019 and normal. After analyzing the data statistically using “Descriptive statistics” in MS-Excel 2010, it was observed that within the period of lockdown, the change in day temperature was -6.66% from normal mean value, however night temperature was least affected as it changes 10.33% and rainfall pattern was 19.27% more from normal mean value. The average change in soil temperature in morning at 5 cm, 10 cm and 20 cm depth in lockdown was -4.65%, 3.74% and 2.65% as compared to year 2019 (1st March to 30th June) mean value and the change in soil temperature in evening at same depths was -5.14%, -11.30% and 0.3% from year 2019 (1st March to 30th June) depicting a slow change in values. With the significant sustainable pattern observed in day and soil temperature parameters and rainfall it can be concluded that lockdown might be an effective tool in reducing speed of climate change in future.

Published: August 2020

Jamun (Syzygium cumini L.) an evergreen wild fruit of utmost importance belongs to Myrtaceae family and grows throughout the Asian subcontinent, Eastern Africa, South America, Madagascar to USA. It is an edible antidiabetic fruit rich in anthocyanins native to India and West Indies. Thus, an attempt was made to develop squash from its fruit and determine quality changes during storage. Various combinations of enzyme assisted extracted juice and sugar syrup were tried and analyzed on the basis of sensory quality attributes to standardize proper combination for squash. The recipe with 35 per cent juice and 40˚B TSS was rate best on the basis of sensory and some physico-chemical characteristics packed in glass and PET bottles and stored for six months under ambient (20-25˚C) and refrigerated temperature conditions (4-7˚C). Squash could be safely stored for a period of six months under both the ambient and refrigerated conditions with mild change in various quality characteristics. Although, the changes in the quality characteristics of the squash were slower in refrigerated storage conditions as compared to ambient conditions. However, both packaging materials viz PET and glass bottles were found suitable with comparably less changes occurring in glass bottle under refrigerated conditions.

Published: August 2020

A field experiment was conducted to determine the dissipation kinetics of carbofuran and its metabolite (Carbofuran 3-OH) in the soil and their terminal residue in sugarcane. The experimental plots were subjected to application of carbofuran 3G (1.0 kg a.i./ha) at the time of planting and 60 days after planting of sugarcane variety CoN 07072 grown with recommended agronomic practices. The soil samples were periodically collected at 0 (2 hrs.), 1, 3, 5, 10, 20, 30, 60 and 90 days after last application of carbofuran. QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) based extraction method adopted to quantify the residues of carbofuran on LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry) from soil, sugarcane juice and leaves were found accurate, sensitive and precise enough. Residues of carbofuran and total carbofuran (Carbofuran + Carbofuran 3-OH) were observed upto 30 days after application and reached below quantification level at 60 days after application in sugarcane grown soil. Carbofuran and total carbofuran followed the first order dissipation kinetics with the half life of 4.18 and 4.17 days, respectively in the experimental soil. Sugarcane leaves and juice contains the residues of carbofuran below quantification limit at the time of harvest of sugarcane.

Authors: Nuhu A. A. , Mhya D. H. , Atiku M. K. , Wudil A. M. 
Published: August 2020

Background: Okra fruits have been found to be efficient in managing hyperlipidemia. But, there are different varieties of Okra, and whether antihyperlipidemic efficiency varies with the varieties has not been reported.
Aim of the Study: The aim of the study was to validate antihyperlipidemic efficiencies of some Okra fruits varieties on rats fed high-fat diet.
Methods: The five varieties of okra fruit was each sliced, air dried and pulverized into powder then extracted with methanol (80%) using Soxhlet extractor and concentrated at 30∘C in a rotary evaporator then finally air dried. Qualitative and quantitative phytochemicals, and proximate analysis were conducted on the extracts. Hyperlipidemia was induce by feeding rats with high-fat diet for 35 days, followed by treating with two selected Okra fruit varieties (NHB-AI-B and Yar kolon) which has the highest extract yield and phytochemicals for 21 days. Nine groups of five rats was used: groups 1-3 (hyperlipidemic rats received NHB-AI-B Okra fruit extract at different doses), group 4-6 (hyperlipidemic rats received Yar kolon Okra fruit extract at different doses), group 7 (positive control rats treated with 10mg/kg Atorvastatin), group 8 (normal control rats fed basal diet) and group 9 (negative control). Serum lipid profile were determined from each rat.
Results: The study confirmed the presence of some important phytochemicals like saponins, tannins, phenolics, flavonoids, fibre etc but differs in concentrations among the varieties where Yar kolon variety emerge highest in almost all the chemical compounds. Rat fed high-fat diet for 35 days developed hyperlipidemia as evident by the elevated triglyceride, cholesterol, LDL-C, body weight and supressed HDL-C. When treated with extracts of NHB-AI-B and Yar kolon Okra fruits varieties, the altered lipid profile were significantly reversed toward normalcy with Yar kolon variety exerting the most efficient activity.
Conclusion: The study showed the five Okra fruit varieties possess same chemical compounds but differs in concentrations among varieties. The extracts of Okra fruits varieties exert significant antihyperlipidemic effect but in varied degrees suggesting variations in their efficiency. This, therefore calls for further study to compare more Okra varieties to determine which one is the most potent and its active agent.

AbstractMolecular designs merging circularly polarized luminescence (CPL) and thermally activated delayed fluorescence (CP‐TADF) using the concept of chiral perturbation appeared recently as a cornerstone for the development of efficient CP‐organic light emitting diodes (CP‐OLED). Such devices could strongly increase the energy efficiency and performances of conventional OLED displays, in which 50% of the emitted light is often lost due to the use of antiglare filters. In this context, herein, ten couples of enantiomers derived from novel chiral emitter designs are reported, exhibiting CPL, TADF, and aggregation induced enhancement emission properties (AIEE). Representing the first structure properties relationship investigation for CP‐TADF materials, this thorough experimental and theoretical work brings crucial findings on the key structural and electronic parameters (isomerism, nature of the carbazole substituents) governing the synergy between CPL and TADF properties. To conclude this study, the first top emission CP‐OLED is elaborated as a new approach of generating CP light in comparison with classical bottom‐emission CP‐OLED architecture. Indeed, the top‐emission configuration represents the only relevant device architecture for future microdisplay applications. Thereby, in addition to offer molecular guidelines to combine efficiently TADF and CPL properties, this study opens new avenues toward practical applications for CP‐OLEDs.

Published: August 2020

AbstractStretchable electronics, which can retain their functions under stretching, have attracted great interest in recent decades. Elastic substrates, which bear the applied strain and regulate the strain distribution in circuits, are indispensable components in stretchable electronics. Moreover, the self‐healing property of the substrate is a premise to endow stretchable electronics with the same characteristics, so the device may recover from failure resulting from large and frequent deformations. Therefore, the properties of the elastic substrate are crucial to the overall performance of stretchable devices. Poly(dimethylsiloxane) (PDMS) is widely used as the substrate material for stretchable electronics, not only because of its advantages, which include stable chemical properties, good thermal stability, transparency, and biological compatibility, but also because of its capability of attaining designer functionalities via surface modification and bulk property tailoring. Herein, the strategies for fabricating stretchable electronics on PDMS substrates are summarized, and the influence of the physical and chemical properties of PDMS, including surface chemical status, physical modulus, geometric structures, and self‐healing properties, on the performance of stretchable electronics is discussed. Finally, the challenges and future opportunities of stretchable electronics based on PDMS substrates are considered.
