Abstract. Understanding the thermal behavior of lakes is crucial for water quality management. Under climate change, lakes are warming and undergoing alterations in their thermal structure, including surface and deep-water temperatures. These changes require continuous monitoring due to the possible major ecological implications on water quality and lake processes. With the scarcity of long-term in situ water temperature datasets, we present a regional long-term water temperature dataset (LakeTSim: Lake Temperature Simulations) produced over 401 French lakes by combining numerical modelling and satellite thermal data. The dataset consists of daily epilimnion and hypolimnion temperatures for the period 1959–2020 simulated with the semi-empirical OKPLM (Ottosson-Kettle-Prats Lake Model). We also describe this model and its performance. We present the uncertainty analysis of simulations with default (parametrized with satellite thermal data over all lakes and in situ measurements) and calibrated (with in situ temperature measurements for each lake) model parameters as well as the sensitivity analysis of the latter. Overall, the 90 % confidence uncertainty range is largest for hypolimnion temperature simulations with a median of 8.5 ºC and 2.32 ºC respectively with default and calibrated parameter values. There is less uncertainty associated with epilimnion temperature simulations with a median of 5.42 ºC and 1.85 ºC before and after parameter calibration. This dataset will help provide insight into the thermal functioning of French lakes. It provides over six decades of epilimnion and hypolimnion temperature data, crucial for climate change studies at a regional scale. The dataset will also be of great advantage for decision making by stakeholders.

Abstract. A high-quality global precipitation product with finer spatiotemporal resolutions and long-term temporal coverage is critical for a variety of science communities (e.g., hydrology, meteorology, climatology, ecology, and agriculture). Here, a novel multi-source precipitation data fusion (MPDF) algorithm, which considers the dependency of precipitation errors on seasonality, was proposed to fully take advantage of the complementary strengths from satellite, reanalysis, and gauge data for generating a higher-quality global precipitation product. Two merging schemes, which used six products (including four satellite precipitation products: IMERG-Late, GSMaP-MVK, TMPA-RT, and PERSIANN-CCS; one reanalysis precipitation product ERA5; one ground-based precipitation product CPCU) and three products (i.e., IMERG-Late, ERA5, and CPCU) as input data sources of the MPDF algorithm respectively, were designed to generate two different high-quality multi-source merged global precipitation products (MGP), i.e., MGP-6P and MGP-3P. The results show that the proposed MPDF algorithm is effective in considering the advantages from satellite, reanalysis, and gauge data. Global comparisons indicate that the MGP suite products with regard to daily mean precipitation share a similar spatial pattern with other global precipitation products (i.e., MSWEP, IMERG-Final, GSMaP-Gauge, ERA5, and CPCU) in most overland regions globally; while large differences between these seven products occur in Australia, southeast China, Europe, near the equator of Africa and South America, and so on. Overall, MGP-3P substantially performs better than the other five research-quality products (i.e., MGP-6P, MSWEP, IMERG-Final, GSMaP-Gauge, and ERA5) in the ground validation on the Chinese mainland, with the highest POD, CC and lowest RMSE of 0.85, 0.71, and 1.21 mm, respectively, at a 3 hourly scale. Especially, the accuracy and detection capability of MGP-3P are the best in most hourly rainfall intensity groups. The MGP-3P product can provide a new precipitation data option for research and applications in the field of hydrology, meteorology, climatology, ecology, and agriculture. MGP-3P (also known as MGP) Version 1.1 is available at the following link: https://www.zenodo.org/record/7386441#.Y8zr4clBxD9 (Chen et al., 2022a).

Published: February 2023

Abstract. Light Detection and Ranging (LiDAR) technology has become a significant factor in producing up-to-date and accurate topographic data in the current world. LiDAR technology has been used for years for many applications, including the efficient creation of digital model for large scale, high accuracy mapping. This technology offers fast, accurate, expedient and cost-effective ways of capturing wide area elevation information to produce highly detailed digital model of the earth. LiDAR is based on airborne laser scanners enables to acquire dense and accurate 3D data of the surveyed area, i.e., the Digital Surface Model (DSM). This paper presents an exploratory study to assess the accuracy of constructed DTM (Digital Terrain Model) and evaluating ground height without surface features using LiDAR Digital Surface Model (DSM). The study area comprised of an undulated area situated at Jinjang in the Klang Valley region, Malaysia covering an area of one kilometre square. LiDAR DSM and DTM constructed and derived from LiDAR were critically assessed with reference to the USGS Map Accuracy Standards. The accuracy of derived DSM and DTM were evaluated using ground control points derived from conventional surveying technique. The constructed models were accessed quantitatively and qualitatively.

Abstract. Low-lying coasts and small islands, such as in the Lesser Antilles, are particularly vulnerable to hurricane-induced marine floods. In September 2017, Category 5 Hurricane Irma, with winds up to 360 km/h, hit the northern Caribbean islands and caused the destruction of 95 % of the structures on Barbuda Island. We investigated the geomorphological impacts and the sedimentological record of this hurricane in Barbuda’s Codrington Lagoon. Following Hurricane Irma, two wide inlets developed across the Codrington sandy barrier. One of these inlets enlarged and was still opened four years later. From available data, it seems that this barrier remained continuous for the last 250 years before Hurricane Irma. At a longer time scale, very high-resolution seismic exploration combined with sediment cores sampled in Codrington Lagoon were used to investigate Irma deposit and environmental changes for the last 3700 years. The evolution from a low-energy small and shallow lagoon to the modern wide and high-energy lagoon recorded by the lagoon sediment-fill was related to both long-term sea-level rise and subsidence. The top of the lagoon fill consists of a thick and extensive sand sheet recording an abrupt increase in energy. Given its location at the top of the cores, its very recent age supported by short-lived radionuclides data, together with large inlets opening and barrier erosion after Irma implying a large sand supply to the lagoon, this sand sheet was attributed to Hurricane Irma. From our cores, it appears that this deposit is unique over more than 3700 years. Both the opening of a new inlet and the thick upper sand sheet support the exceptional character of Irma at the scale of centuries to millennia. Our study reinforces the idea that Hurricane Irma was exceptional in terms of intensity and may be associated with global warming.

Abstract. The Arctic climate system is changing rapidly. These large changes will have implications in the Arctic and beyond. One of the main components of the Arctic climate system are Arctic cyclones. The strong coupling between the sea ice and Arctic cyclones makes it an important topic in the warming climate. In this study, an ensemble of CMIP6 model output was utilized from 1985–2014, to determine how well the chosen models depict Arctic cyclones and their relationship with sea ice. A comprehensive climatology of Arctic cyclones and sea ice concentrations (SIC) was provided based on selected models from5 CMIP6 and the results were compared to the ERA5 product. The model results did closely match reanalysis data in depicting the observed sea ice trend. However, we found that the model results struggled to reproduce the strongly coupled relationship between the declining sea ice and Arctic cyclones. The local cyclogenesis in the Arctic was shown to be underestimated, which led to an overall underestimation of Arctic cyclones in the CMIP6 model results. The results also showed differences between model results and ERA5 with regard to cyclone intensities. The the magnitude and sign of the intensity differences varied based10 on the nominal resolution of the model, their surface roughness parametrization and cyclogenesis location.

The available drugs against coronavirus disease 2019 (COVOD-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are limited. This study aimed to identify ginger-derived compounds that might neutralize SARS-CoV-2 and prevent its entry into host cells. Ring compounds of ginger were screened against spike (S) protein of alpha, beta, gamma, and delta variants of SARS-CoV-2. The S protein FASTA sequence was retrieved from Global Initiative on Sharing Avian Influenza Data(GISAID) and converted into “.pdb” format using Open Babel tool. A total of 306 compounds were identified from ginger through food and phyto-databases. Out of those, 38 ring compounds were subjected to docking analysis using CB Dock online program which implies AutoDock Vina for docking. The Vina score was recorded, which reflects the affinity between ligands and receptors. Further, the Protein Ligand Interaction Profiler (PLIP) program for detecting the type of interaction between ligand-receptor was used. SwissADME was used to compute druglikeness parameters and pharmacokinetics characteristics. Furthermore, energy minimization was performed by using Swiss PDB Viewer (SPDBV) and energy after minimization was recorded. Molecular dynamic simulation was performed to find the stability of protein-ligand complex and root-mean-square deviation (RMSD) as well as root-mean-square fluctuation (RMSF) were calculated and recorded by using myPresto v5.0. Our study suggested that 17 out of 38 ring compounds of ginger were very likely to bind the S protein of SARS-CoV-2. Seventeen out of 38 ring compounds showed high affinity of binding with S protein of alpha, beta, gamma, and delta variants of SARS-CoV-2. The RMSD showed the stability of the complex was parallel to the S protein monomer. These computer-aided predictions give an insight into the possibility of ginger ring compounds as potential anti-SARS-CoV-2 worthy of in vitro investigations.

Sleep is a crucial lifestyle component that improves general health. The effect of diet and consumption of certain foods has been reported to have a significant effect on sleep patterns and sleep quality. Many supplements were used to help promote healthy sleep. However, the connection between some food factors and sleep is rather complicated. The nutritional components change depending on the food habits and the digestive and metabolic processes of each person. Several studies and systematic reviews reported potential benefit of specific nutrients and their role in sleep including: high-fiber and low-sugar carbohydrates, protein, fatty acids, several vitamins such as vitamins D, C, and B and electrolyte especially magnesium. Others were reported could disrupted sleep such as caffeine, alcohol and excess sugar. This article discussed nutrients that are potential to play a role in sleep quality, their mechanisms, and food recommendation that can be made to help improve sleep quality and sleep wellness.

Graphene Oxide (GO) is one of the common members of the graphene family owing to its unprecedented and unique properties. These properties attract researchers to use GO in several potential applications such as a transparent electrode in light-emitting diodes (LED), biosensors and solar cells, etc. In this work, GO was produced through the oxidation of graphite by potassium permanganate using modified Hummer’s method and this was followed by ozone treatment. The crystallographic structure, chemical properties, surface morphologies, and optical properties of before and after treatment of GO were determined by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and UV- visible spectroscopy. The FTIR observation confirmed the formation of GO from graphite flakes. XRD results showed peak at11.6˚ with a different interlayer spacing of 0.7nm and 0.8nm for GO and ozone-treated graphene oxide (O- GO) respectively. While for both GO and O- GO all the peaks were at the same position. Further, SEM micrographs of GO exhibited the multilayered graphene oxide with variable thickness. While the rough surface of O- GO suggests the reduction of GO particle size due to ozonation. Ultraviolet-visible spectra of GO at 223.2 nm was noted which is attributed to atomic C- C bonds but O- GO exhibited the peak shift at 232.7 nm thereby suggesting a higher surface area.

The purpose this research was to study the decomposition of phenol in water under the influence of UV radiation in the presence of nanoparticles TiO2 and methyl-3-amicrotonate.
The photochemical decomposition of phenol in the presence of UV in a system of TiO2+N containing substances was carried out. The TiO2 nanoparticles used in the reaction had a size from 10 to 30 nm and belonged to the rutile phase. Nano-TiO2 was studied by X-ray diffraction, TEM and SEM methods. All the XRD peaks were well-defined and corresponded to rutile phase TiO2. From the line broadening of the (101) diffraction peak by Scherrer’s method, the average crystal size TiO2 is about 10.3. The specific surface areas for TiO2 is 159.6 m2/g. X-ray structure analysis Fig of the studied nanocomposite materials were recorded on the Rigaku Mini Flex 600s powder diffractometer. X-ray tube with copper anode (Cu-Kα radiation, 30 kV and mA) was used to draw the diffraction specters at room temperature. At 2θ = 20and#176;- 80and#176; with discrete growth mode these specters were obtained as Δ2θ = 0.05and#176; and the exposure time was τ =5 seconds.
The photochemical process lasted 1 hour using a very small amount of white powder and 0.05 gr of TiO2 nanoparticles synthesized by the sol-gel method and N-containing substance. For the process 1 mgL-1of phenol solution was used. The process was monitored with a spectrophotometer “Varian Cary 50”. After the photochemical decomposition of phenol, the reaction product was analyzed on an Agilent 6980N/5975 by the method GC-MSD. The goal was to determine the percentage of photochemical decomposition of phenol in TiO2+N system and 60% decomposition of phenol was defined.

Herein, we report four self-assembly Iron(II/III) complex consisting triethanolamine (TEOA) as ligand and an FeIII(TPA)Cl3 (TPA= 3-(2-pyridine methyl) amine) as contrast catalyst, for photochemical reduction of CO2 to CO under visible light. The photocatalytic systems were assembled by [Ru(bpy)3]Cl2 as photosensitizer, and 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo-[d]-imidazole (BIH) as electron donor. Experiments are conducted to study the relationship between CO production and the external ions. Different external counterions are provided to assist the discussion of the influence of these external ions on catalysis. Density functional theory calculations confirmed that the external ions have an effect on the CO yield. Moreover, a mechanism involving proton-coupled electron transfer is proposed.

Postoperative shoulder imbalance (PSI) is a common complication following adolescent idiopathic scolio- sis (AIS) surgery. There is little data available in literature on prediction of PSI. Prospectively collected data of AIS with thoracic curve (Lenke 2), operated in 2014-2018 at a single scoliosis-center, were analyzed retrospectively using X-rays of whole spine and traction films (TA): age, Cobb-angle of proximal (PC), major thoracic (MC) and lumbar curve (LC), shoulder height [mm], clavicle angle [°], T1-tilt [°], plumb line [mm]. Results as mean ± standard deviation. Change over time (postOP- FU) compared using t-test (≥=0.05). Correlation of preOP parameters and curve correction with PSI (|≥|15mm) was analyzed by correlation (Pearson)- and regression-classification-analysis. 32 AIS, average age of 14±1.3 yrs. FU 16 months (84%). Curve correction was 52.5% (PC), 70.1% (MC), 69.9% (LC), significant change in FU for PC (-2.4°, p>0.05), not for MC, LC (p=0.2, p=0.6). Shoulder height was negative if right- side up: 2.9±15.1mm (preOP), 5.5±15.0 mm (TA), 17.9±14.9mm (postOP), 17.4±8.4mm (FU). 28% had preOP shoulder imbalance, 69% postOP and 44% FU had PSI. Shoulder height on TA correlated to change preOP to FU (r=0.62) and preOP shoulder height (r=-0.85), clavicle angle had strong correlation (r=- 0.81). Regression-classification-analysis: correction of MC>62.4%, 81.5% of cases had PSI; with correction of MC>64.9% and LC>93.2%, 51.9% of cases had PSI. PSI is a common in Lenke2 AIS. In preOP planning TA, shoulder position and clavicle angle should be considered to prevent PSI. Correction of MC should be moderate, overcorrection of the LC avoided.

The “dark sight” and “bright side” of innovation: A study of paradoxes and tensions in creativity and innovation
Authors: Potočnik Kristina
Published: February 2023

Although innovative teams are typically assumed to be successful teams, little is known about the process of innovation in teams that face stressful, demanding and/or unexpected conditions while carrying out their everyday operations. Although innovation may be required to cope with such conditions and the vast literature on organizational innovation certainly suggests that the more teams and individuals innovate the better, at the same time it might provoke further disruption and stress, leading to negative rather than beneficial outcomes for teams and individuals. In fact, innovation has been associated with increased uncertainty and complexity all of which may further increase the feelings of stress and ultimately lead to poorer rather than improved performance. These arguments are consistent with the literature on vicious circles in organizations which may emerge when actors fail to fully understand the complexity of the situation within which they are operating. Thus, interventions are made whose consequences are not understood, creating even more problems that demand attention.

This talk will be based on a five-year program of research that has focused on studying small teams engaged in an intense simulation exercise that involves precision and time-critical tasks in an unpredictable environment. We explored to what extent the experience of stressors triggers teams to innovate and, in turn, what effects team innovation has on team performance and individual team member well-being. We put forward competing hypotheses suggesting both, beneficial and detrimental effects of stress-driven innovation as attempts to innovate in the face of unexpected events and emerging problems may help teams overcome these; however, it may also trigger the “vicious circle” effect, leading to poorer team performance and additional stress for team members.

Our simulation-based research design with randomly allocated teams operating under the same environmental conditions can help us rule out alternative explanations for our results, such as the effects of past experience with the task, familiarity between team members and other contextual conditions on the relationship between innovation and team performance and individual team member well-being, respectively. We contribute to the literature on paradoxes and tensions in creativity and innovation by showing how stress-driven innovation is a paradoxical phenomenon that might be both beneficial and dysfunctional.

Wet noodles are a type of noodle with a fairly high water content (35-52%), so it is easy to spoil if stored for more than 12 hours at room temperature. Misuse of the addition of borax and formalin by irresponsible food manufacturers, aims to make wet noodles last longer. This study aims to determine whether the wet noodles sold in several traditional markets in Sidoarjo contain harmful ingredients borax and formaldehyde. The research design in this study began with organoleptic observations on several wet noodles found in several traditional markets in Sidoarjo Regency, followed by a borax test using a borax rapid test kit and a formalin test with UV Vis spectrophotometry and Nash reagent. Based on the test results, it can be concluded that organoleptic observations showed that there were 3 samples of wet noodles with a floury smell and 5 samples with a sour smell, in terms of texture all samples showed a soft and easily broken texture while in terms of color there were 5 samples that were pale yellow and 3 samples were bone white. Based on the results of the qualitative test of borax, all samples of wet noodles were negative for borax and based on the results of the quantitative test of formalin with UV Vis spectrophotometry, showed a negative result of formalin.

Published: February 2023

Papaya is botanically known as Carica papaya L. It belongs to Caricaceae family and it has chromosome number is 2n=18. Papaya is native to Tropical America. It was introduced in the 16th century in India. The term ‘Plant Growth Regulators’ is relatively new in use. In previous literature, these were revealed as Hormones. “Hormone” is a Greek word derived from “hormao” which means to stimulate. Thimonn (1948) optional the use of the term phytohormons in place of hormone of plants. He defined phytohormons as the organic substances which are formed naturally in plants, synthesized in one part and usually trans-located to other part of plants where in every small quantity effect on the growth and other physiological activates of the plants. The term growth regulator is used for the materials which work similar to phytohormons but synthetic in nature.

Published: February 2023

Kombucha is a fermented tea made from tea broth 5-8% Sucrose (granulated sugar) and SCOBY (symbiotic culture of bacteria and yeast), it is an alcoholic drink with 0.5 -2.5% alcohol. The origin of kombucha tea is said to be from China. The kombucha tea takes about 7-10 days for its fermentation. The fermentation takes place in two stages, wherein the first stage takes about 7-10 days, and the pellicle is formed in the air-water interface and in the second stage the flavoring of the kombucha is done with the fruit pulp and it is left for 10 days. In the first stage of fermentation, it forms a polymeric cellulose pellicle (SCOBY) with the help of certain species of bacteria and yeast-like lactic acid bacteria, Acetic acid bacteria and Saccharomyces species. The consumption of kombucha is good for health. The SCOBY is a biofilm formed by the action of acetic acid bacteria, lactic acid bacteria, and yeast and it is made of cellulose polymeric compound which can trap the microorganisms to a certain extent and retain them on the filter pad (SCOBY). The increased use of nitrocellulose membrane filter is used for filtering microorganisms from the sample is used extensively as it gives out efficient results, but the continuous and increased use of nitrocellulose filter is not good for the environment and for the human population who live near the industries where it is made. This study focuses on the use of SCOBY as a filter pad on various samples and finding out its efficiency when compared to the nitrocellulose membrane filter pad.

This paper aims at alternative fuel technology for diesel engine and environmental protection. The exhaust emissions from diesel engine are particulate matter (PM), nitrogen oxide (NOx ) levels, carbon mono oxide (CO) emissions and un-burnt hydro carbons (UBHC) and cause severe health hazards when they are inhaled in. They also cause environmental disorders like Global warming, Green-House effect, acid rain etc,. Hence control of these emissions is urgent and an immediate step. Vegetable oils and alcohols are important substitutes for diesel fuel, as they are renewable in nature. Though vegetable oils have comparable properties with diesel fuel, however, they have high viscosity and low volatility causing combustion problems in diesel engines. Alcohols have high volatility but low Cetane number (a measure of combustion quality in diesel engine). Plastic oil derived from waste plastic collected from debris by the process of pyrolysis has equitant calorific value with diesel fuel. However, its viscosity is higher than diesel fuel calls for low heat rejection (LHR) diesel engine. The concept of LHR diesel engine is to minimize the heat flow to the coolant there by increase of thermal efficiency. This LHR engine is useful for burning high viscous and low calorific value fuels. LHR engine consisted of ceramic coated cylinder head engine. The exhaust emissionsof PM, CO, NOx and UBHC with plastic oil were determined with conventional engine (CE) and LHR engine with varied injection timing at full load operation of the engine. Injection timing was varied with an electronic sensor. PM was determined by AVL Smoke meter, while NOx , CO and UBHC were measured by Netel Chromatograph multi gas analyzer at full load operation of the engine. The data was compared with neat diesel operation on conventional engine.

Spot blotch caused by Bipolaris sorokiniana is one of the most serious diseases of barley in tropical areas where barley and wheat are grown. A field experiment was conducted at Regional Research Station Masodha, ANDUA&T, Kumarganj, Ayodhya, Uttar Pradesh during Rabi season. To evaluate the effect of different dates of sowing and chemical and organic amendments on spot blotch and consequently on seed quality of barley. The experiment was conducted during the Rabi season 2016-17 under hotspot area of spot blotch. RD-2794 was sown in a split plot manner with two dates of sowing.The experiment was performed in split plot design with three replications comprising two different dates of sowing, i.e. mid- November (D1 ) and mid-December (D2 ) in the main plot and chemical and organic amendments viz., RDF (60N:30P:20K kg/ hectare) -T1 , FYM @ 5 t/h-T2 , T1 + Mulch@ 6 t/h-T3 , T1 + FYM @ 5t/hec + Mulch @ 6t/ hec.-T4 , T4 + 2 spray of zinc sulphate @ 0.5 %-T5 , T4 + 2 spray of KCl @0.5%-T6 and T5 + 2 spray of KCl @ 0.5 %-T7 in the sub plot. Results revealed that minimum disease severity (46.9%) with maximum disease control (39.98%) and per cent seed infection (5.5%) were recorded in D1 × T7 . The interpretation of data revealed that there was highly positive and significant correlation (r=0.95) between disease severity and per cent seed infection. The maximum 1000-seed weight (43.41g) and yield (38.67 q/ha) with maximum yield gain (57.25%) was also recorded in D1 × T7 . The same treatment combination was also useful in maximizing the seed quality in terms of seed viability (98%), Germination (97%), seedling length (27.30cm) and vigour index-I (2648.153) when the freshly harvested seeds were tested in seed testing laboratory. Spot blotch is a serious disease of barley spreads primarily through infected seeds and reduced the yield up to 30%. The disease can be minimized by sowing the crop timely i.e. mid-November with recommended dose of fertilizers + FYM @ 5 t/ha+ Mulch@ 6 t/ha+ 2 spray of zinc sulphate @ 0.5 % + 2 spray of KCl @ 0.5 % at flag leaf and post anthesis stage which improves the seed quality.
