Published: February 2022

Calcium (Ca) is an essential secondary macronutrient which necessary plant mineral frequently added to fertilizers to promote plant development and resistance to abiotic and biotic stressors. Applying Ca to soils suffices to meet crops’ Ca requirements. Regrettably, its function is obscure. Thus, it is critical to maintain enough nutrient availability through fertilizers or alter the soil environment for oil palm seedlings to grow and thrive. This study investigates the effects of different Ca sources on vegetative growth in oil palm seedlings. This experiment was carried out for nursery evaluation using 5-months old of oil palm seedlings with varying sources of Ca (C1–calcium chloride, CaCl2; C2–calcium sulfate, CaSO4; C3-calcium nitrate, CaNO3; C4–calcium carbonate, CaCO3; C5–calcium oxide, CaO, C6–calcium hydroxide, Ca(OH)2; and C7–water leach purification and neutralization underflow, NUF-WLP) and grown in a polybag containing beach ridges interspersed with swales (BRIS) soil within six months in Malaysian Palm Oil Board (MPOB) nursery, Seksyen 15, Bandar Baru Bangi. Five concentration levels of Ca (T1–200 ppm, T2–250 ppm, T3–300 ppm, T4–1,000 ppm, and T5–1,500 ppm) were used in a completely randomized design (CRD) with ten replications for each. Based on the total biomass of oil palm seedlings at 24 weeks after treatment with various sources of Ca, the result confirmed that C2 oil palm seedlings were more significant in size and denser at the root than other Ca types. The result is an essential indicator that C2 effectively increased the total biomass of oil palm seedlings at 1,000 ppm of Ca (T4); hence it was the best Ca source to improve the growth and development of oil palm seedlings throughout the experimental period at p≤0.05.

Published: February 2022

Rattan Calamus spp. is a high commercial value palm from the subfamily Calamoideae the primary source for cane in the well-developed rattan industry. Most studies on rattan have focused on its biodiversity, distribution, quality, strength, physical, mechanical, and morphological properties and genetics. Still, only a few have investigated the association of rattan with arbuscular mycorrhizal (AM) fungi. These mycorrhizal fungi are well known to play essential functions as promoting plant growth, maintaining plant community biodiversity and nutrient cycles in soil. This study aims to identify the established AM fungi community and their ecological interactions with Calamus spp. in the Belum-Temengor Forest Complex, Perak, Malaysia. Calamus spp. roots and their rhizospheric soil samples were collected from six sampling sites in the Belum-Temengor Forest Complex, one of the oldest rainforests in the world. The degree of mycorrhizal colonisation in Calamus spp. was evaluated using the grid lines method. At the same time, the AM fungi spore diversity in the rhizospheric soils were isolated using the wet sieving method and identified taxonomically analysed into different genera. Calamus insignis showed the highest degree of mycorrhizal colonisation amongst all the Calamus spp. present on the sampling sites. The AM fungi spores isolated from the rhizospheric soil from Belum-Temengor Forest Complex belonged to the genera Acaulospora, Entrophospora, Gigaspora, Glomus, and Scutellospora. Glomus was the most frequently found genus in all the sampling sites. This study is the first record of the AM fungal diversity found in the Belum-Temengor Forest Complex.

Materialism, conspicuous consumption,
and brand engagement in self-concept:
a study of teenagers
Authors: Kolańska-Stronka Magdalena , Gorbaniuk Oleg
Published: February 2022

Introduction

Contemporary adolescents, also known as Generation Z, are an important group of consumers due to the role they play in today’s economy. The present study investigates the relationship between materialism and brand engagement in self-concept (BESC) and whether conspicuous consumption is a mediator of this relationship in early, middle, and late adolescence.

Material and methods

The participants were 581 students from Poland, aged 13 to 17 (M = 15 years, SD = 1.42); 51.6% of them were girls. Data were gathered using a demographic information form, the Youth Materialism Scale, the Conspicuous Consumption Scale, and a BESC Scale, completed during personal interviews.

Results

The study indicated an association of higher materialism and higher conspicuous consumption with a higher level of BESC, where conspicuous consumption acts as a mediator of the correlation between materialism and BESC. Age also moderates this mediation, i.e., the older the teenagers are, the weaker is the analyzed mediation effect.

Conclusions

The research is part of an essential step in understanding the mechanism of BESC by testing a moderated mediation model in teenagers.
Temporary change in personality states among social media users: effects of Instagram use on Big Five personality states and consumers’ need
for uniqueness
Authors: Drążkowski Dariusz , Pietrzak Sebastian , Mądry Laura
Published: February 2022

Introduction

Research suggests that certain personality traits influence the frequency of social media use. However, the potential effect of social media use on personality states merits investigation as well, in light of the personality dynamics approach.

Material and methods

We conducted an experimental study in which 325 Instagram users were asked to count selfies and emoticons on their Instagram profiles (experimental condition) or their phones (control condition). Subsequently, all participants responded to questions from the Big Five personality inventory and scale to measure the need for uniqueness in consumption.

Results

Instagram users had a higher neuroticism state and a higher need for uniqueness compared with the controls. In terms of the other Big Five states, we observed no differences between the study conditions.

Conclusions

Our study explores the novel direction of the relationship between social media use and personality, suggesting that using Instagram can temporarily change personality states.

Authors: Sousa Tiago , Sarmento Hugo , D. Harper Liam , Valente-Dos-Santos João , Vaz Vasco
Published: February 2022

The purpose of this paper was to review the available literature on match analysis in rink hockey. To be included in this review, the publications should have been written in English or Portuguese, have contained relevant data about match analysis in rink hockey, and have been published as original papers, reviews, book chapters, or academic works. A systematic review of Web of Science, SPORTDiscus, PubMed, Scopus, b-on, and Open Access Scientific Portuguese Repository (RCAAP) was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines on July 24, 2020. A risk-of-bias quality form was adapted to evaluate the publications. To make a fair comparison between studies of different designs, a percentage score was calculated as a final measure of methodological quality. From the 20 selected studies, 8 were classified as having excellent methodological quality and 12 had good methodological quality. To organize the results, the material was categorized in 2 analysis levels: (i) dependent on the type of analysis performed; (ii) based on the type of variables analysed. This review highlights that rink hockey could be characterized as a sport where half of the offensive actions end with a shot at goal, but only a small number of these shots end with a goal. Furthermore, there are differences in technical demands between player positions and reductions in movement intensity in the second halves of matches. Future research should provide more scientific knowledge on the sport, using new technologies and new approaches to study tactical sequential events.

Published: February 2022

The project is designed for Solar powered pedestal street lights that uses solar power from PV cells. For controlling the charging of the battery a charge controller is been used, and an LDR is used to sense the light on day as well as the evening time. The intensity of street lights is required to be kept high during the peak hours. The street lights are switched on using a sensing device LDR LED lights at the dusk and then switched off automatically when the timer set in the timer relay module stops. Due to which there is low energy consumption and the system works long life so that they can fast replace conventional lights world over. White light emitting diode (LED) replaces the HID lamps due to which the light gets saved and the system works without any problem. For energy saving of solar based system, also a charge controller is used to protect the battery from over charging, overloading and deep dischargeing protection. A light sensing device LDR (Light Dependent Resistance) is used, whose resistance reduces drastically for sensing purposes. In the measuring circuit the light intensity is monitored using an Light Dependent Resistance sensor and an signal from ldr sensor is send to the relay timer module and the times gets started and, after the time finishes the relay attached to the relay timer module gets open and the street lights stops. The design for this proposed project is modeled in PROTEUS 8 and acceptable results came at the end.
Analysis of low force friction welding process in the industrial environment
Authors: Zurawski Pawel
Published: February 2022

The low force friction welding process is a relatively new technology for welding two components together. The process developed just a few years ago has not been sufficiently researched to date to extend the knowledge about the process and its advantages. Under this process, most of the heat energy required for the welded joint comes from the induction coil. The process has many advantages over the butt friction welding method that determine the industrial application of the new technology. The advantages certainly include the lack of butt, an option of welding various materials, easy control of process parameters, short cycle time, and process stability. One of the companies using this technology is Federal Mogul Gorzyce based in Poland, using low force friction welding to produce small steel pistons. This paper analyses the low force friction welding process. The key process parameters, welding stages, and an analysis of the welded joint were presented. This paper discusses the issue of low force friction welding because of the attractiveness of this technique for the industrial application and the scarcity of literature relating to this process.

Published: February 2022

Abstract. A series of experiments were designed and conducted in the Manchester Aerosol Chamber (MAC) to study the photooxidation of single and mixed biogenic (isoprene and α-pinene) and anthropogenic (o-cresol) precursors in the presence of NOx and ammonium sulphate seed particles. Several online techniques (HR-TOF-AMS, Semi-Continuous GC-MS, NOx and O3 analyser) were coupled to the MAC to monitor the gas and particle mass concentrations. Secondary Organic Aerosol (SOA) particles were collected onto a quartz fibre filter at the end of each experiment and analysed using liquid chromatography ultra-high resolution mass spectrometry (LC-Orbitrap MS). The SOA particle chemical composition in single and mixed precursor systems was investigated using non-targeted accurate mass analysis of measurements in both negative and positive ionization modes, significantly reducing data complexity and analysis time, providing an more complete assessment of the chemical composition. This non-targeted analysis is not widely used in environmental science and never previously in atmospheric simulation chamber studies. Products from α-pinene were found to dominate the binary mixed α-pinene / isoprene system in terms of signal contributed and the number of particle components detected. Isoprene photooxidation was found to generate negligible SOA particle mass under the investigated experimental conditions and isoprene-derived products made a negligible contribution to particle composition in the α-pinene / isoprene system. No compounds uniquely found in this system contributed sufficiently to be reliably considered as a tracer compound for the mixture. Methyl-nitrocatechol isomers (C7H7NO4) and methyl-nitrophenol (C7H7NO3) from o-cresol oxidation made dominant contributions to the SOA particle composition in both the o-cresol / isoprene and o-cresol / α-pinene binary systems in negative ionization mode. In contrast, interactions in the oxidation mechanisms led to the formation of compounds uniquely found in the mixed o-cresol containing binary systems in positive ionization mode. C9H11NO and C8H8O10 made large signal contributions in the o-cresol / isoprene binary system. The SOA molecular composition in the o-cresol / α-pinene system in positive ionization mode is mainly driven by the large molecular weight compounds (e.g. C20H31NO4, and C20H30O3) uniquely found in the mixture. The SOA particle chemical composition formed in the ternary system is more complex. The molecular composition and signal abundance are both markedly similar to those in the single α-pinene system in positive ionization mode, with major contributions from o-cresol products in negative ionization mode.

Abstract. High ice water content (HIWC) regions in tropical deep convective clouds, composed of high concentrations of small ice crystals, were not reproduced by Weather Research and Forecasting (WRF) model simulations at 1 km horizontal grid spacing using four different bulk microphysics schemes (i.e., the WRF single‐moment 6‐class microphysics scheme (WSM6), the Morrison scheme and the Predicted Particle Properties (P3) scheme with one- and two-ice options) for conditions encountered during the High Altitude Ice Crystals (HAIC) and HIWC experiment. Instead, overestimates of radar reflectivity and underestimates of ice number concentrations were realized. To explore formation mechanisms for large numbers of small ice crystals in tropical convection, a series of quasi-idealized WRF simulations varying the model resolution, aerosol profile, and representation of secondary ice production (SIP) processes are conducted based on an observed radiosonde released at Cayenne during the HAIC-HIWC field campaign. The P3 two-ice category configuration, which has two “free” ice categories to represent all ice-phase hydrometeors, is used. Regardless of the horizontal grid spacing or aerosol profile used, without including SIP processes the model produces total ice number concentrations about 2 orders of magnitude less than observed at −10 ∘C and about an order of magnitude less than observed at −30 ∘C but slightly overestimates the total ice number concentrations at −45 ∘C. Three simulations including one of three SIP mechanisms separately (i.e., the Hallett–Mossop mechanism, fragmentation during ice–ice collisions, and shattering of freezing droplets) also do not replicate observed HIWCs, with the results of the simulation including shattering of freezing droplets most closely resembling the observations. The simulation including all three SIP processes produces HIWC regions at all temperature levels, remarkably consistent with the observations in terms of ice number concentrations and radar reflectivity, which is not replicated using the original P3 two-ice category configuration. This simulation shows that primary ice production plays a key role in generating HIWC regions at temperatures <-40 ∘C, shattering of freezing droplets dominates ice particle production in HIWC regions at temperatures between −15 and 0 ∘C during the early stage of convection, and fragmentation during ice–ice collisions dominates at temperatures between −15 and 0 ∘C during the later stage of convection and at temperatures between −40 and −20 ∘C over the whole convection period. This study confirms the dominant role of SIP processes in the formation of numerous small crystals in HIWC regions.

Abstract. There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed a two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures the aerosol absorption coefficient at 532 and 1064 nm. Here we describe its design, calibration and mode of operation and evaluate its applicability, limits and uncertainties. The 532 nm channel was calibrated with ~1 µmol/mol NO2, whereas the 1064 nm channel was calibrated using measured size distribution spectra of nigrosin particles and a Mie calculation. Since the aerosolized nigrosin used for calibration was dry, we determined the imaginary part of the refractive index of nigrosin from the absorbance measurements on solid thin film samples. The obtained refractive index differed considerably from the one determined using aqueous nigrosin solution. PTAAM-2λ has no scattering artefact and features very low uncertainties: 4 % and 6 % for the absorption coefficient at 532 nm and 1064 respectively; and 9 % for the absorption Ångström exponent. The artefact-free nature of the measurement method allowed us to investigate the artefacts of filter photometers. Both the Aethalometer AE33 and the CLAP suffer from the cross-sensitivity to scattering – this scattering artefact is most pronounced for particles smaller than 70 nm. We observed a strong dependence of the filter multiple scattering parameter on the particle size in the 100–500 nm range. The results from the winter ambient campaign in Ljubljana showed similar multiple scattering parameter values for ambient aerosols and laboratory experiments. The spectral dependence of this parameter resulted in AE33 reporting the absorption Ångström exponent for different soot samples with values biased 0.17–0.3 higher than the PTAAM-2λ measurement. Photothermal interferometry is a promising method for reference aerosol absorption measurements.
A question of scale: modelling biomass, gain and mortality distributions of a tropical forest
Authors: Knapp Nikolai , Attinger Sabine , Huth Andreas
Published: February 2022

Abstract. The quantification of forest carbon budgets is important for understanding the role of forests in the global climate system. Given the variety of different methodologies (inventories, remote sensing, modelling) and spatial resolutions involved, methods for consistent transfer between scales are needed. In this study, the scaling of variables, which drive the carbon budget, was investigated for a tropical forest in Panama. Based on field inventory data from Barro Colorado Island, spanning 50 ha over 30 years, the distributions of aboveground biomass, biomass gain and mortality were derived at different spatial resolutions, ranging from 10 to 100 m. Methods for fitting parametric distribution functions were compared. Further, it was tested under which assumptions about the distributions a simple stochastic simulation forest model could best reproduce observed biomass distributions at all scales. Also, an analytical forest model for calculating biomass distributions at equilibrium and assuming mortality as a white shot noise process is presented. Scaling exponents of about −0.47 were found for the standard deviations of the biomass and gain distributions, while mortality showed a different scaling relationship with an exponent of −0.3. Lognormal and gamma distribution functions fitted with the moments matching estimation method allowed for consistent parameter transfers between scales. Both forest models (stochastic simulation and analytical solution) were able to reproduce observed biomass distributions across scales, when combined with the derived scaling relationships. The study provides insights about transferring between scales and its effect on frequency distributions of forest attributes, which is particularly important for the increasing efforts to combine information from sources such as inventories, remote sensing and modelling.

Abstract. Antarctic sea ice forms a critical part of the Southern Ocean and global climate system. The behaviour of Antarctic sea ice throughout the last glacial-interglacial (G-IG) cycle (12,000–130,000 years) allows us to investigate the interactions between sea ice and climate under a large range of mean climate states. Understanding both temporal and spatial variations in Antarctic sea ice across a G-IG cycle is crucial to better understanding the G-IG regulation of atmospheric CO2, ocean circulation, nutrient cycling and productivity. This study presents published qualitative and quantitative estimates of G-IG sea ice from twenty four marine sediment cores, and an Antarctic ice core. Sea ice is reconstructed from the sediment core records using diatom assemblages and from the ice core record using sea-salt sodium flux. Whilst all regions of the Southern Ocean display the same overall pattern in G-IG sea-ice variations, the magnitudes and timings vary between regions. Sea-ice cover is most sensitive to changing climate in the output regions for the Weddell Sea and Ross Sea Gyres, as indicated by the greatest magnitude changes in sea ice in these areas. In contrast the Scotia Sea sea-ice cover is much more resilient to moderate climatic warming, likely due to the meltwater stratification from high iceberg flux through ‘iceberg alley’ helping to sustain high sea-ice cover outside of full glacial intervals. The differing sensitivities of sea ice to climatic shifts between different regions of the Southern Ocean has important implications for the spatial pattern of nutrient supply and primary productivity, which subsequently impact carbon uptake and atmospheric CO2 concentrations changes across a G-IG cycle.

Abstract. Fossil-fuel-based energy use in agriculture leads to CO2 and
non-CO2 emissions. We focus on emissions generated within the farm gate
and from fisheries, providing information relative to the period 1970–2019,
for both energy use, as input activity data and the associated greenhouse
gas (GHG) emissions. Country-level information is generated from United Nations Statistics Division (UNSD) and
International Energy Agency (IEA) data on energy in agriculture (including forestry and fisheries),
relative to use of gas/diesel oil, motor gasoline, liquefied petroleum gas
(LPG), natural gas, fuel oil and coal. Electricity used within the farm gate
is also quantified, while recognizing that the associated emissions are
generated elsewhere. We find that, in 2019, annual emissions from energy use
in agriculture were about 523 million tonnes (Mt CO2eq yr−1​​​​​​​),
while when including electricity they were 1029 Mt CO2eq yr−1, having
increased 7 % from 1990. The largest emission increase from on-farm fuel
combustion was from LPG (32 %), whereas significant decreases were
observed for coal (−55 %), natural gas (−50 %), motor gasoline (−42 %)
and fuel oil (−37 %). Conversely, the use of electricity and the associated
indirect emissions increased 3-fold over the 1990–2019 period, thus
becoming the largest emission source from energy use in agriculture since
2005. Overall, the global trends were a result of counterbalancing effects:
marked decreases in developed countries in 2019 compared to 1990
(−273 Mt CO2eq yr−1) were masked by slightly larger increases in
developing and emerging economies (+339 Mt CO2eq yr−1). The
information used in this work is available as open data at

TrackMatcher — A tool for finding intercepts in tracks of geographical positions
Authors: Bräuer Peter , Tesche Matthias
Published: February 2022

Abstract. Working with measurement data in atmospheric science often necessitates the collocation of observations from instruments or platforms at different locations, with different geographical and/or temporal data coverage. Varying complexity and abundance of the different data sets demand a consolidation of the observations. This paper presents a tool for (i) finding temporally and spatially resolved intersections between two- or three-dimensional geographical tracks (trajectories) and (ii) extracting of observations and other derived parameters in the vicinity of intersections to achieve the optimal combination of various data sets and measurement techniques. The TrackMatcher tool has been designed specifically for matching height-resolved remote-sensing observations along the ground track of a satellite with position data of aircraft (flight tracks) and clouds (cloud tracks) and intended extension for ships (shiptracks) and air parcels (forward and backward trajectories). The open-source algorithm is written in the Julia programming language. The core of the matching algorithm consist of interpolating tracks of different objects with a piecewise cubic Hermite interpolating polynomial with subsequent identification of an intercept point by minimising the norm between the different track point coordinate pairs. The functionality wrapped around the two steps allows for application of the TrackMatcher tool to a wide range of scenarios. Here, we present three examples of matching satellite tracks with the position of individual aircraft and clouds that demonstrate the usefulness of TrackMatcher for application in atmospheric science.
Exploring hydrologic post-processing of ensemble streamflow forecasts based on affine kernel dressing and non-dominated sorting genetic algorithm II
Authors: Xu Jing , Anctil François , Boucher Marie-Amélie
Published: February 2022

Abstract. Forecast uncertainties are unfortunately inevitable when conducting a deterministic analysis of a dynamical system. The cascade of uncertainty originates from different components of the forecasting chain, such as the chaotic nature of the atmosphere, various initial conditions and boundaries, inappropriate conceptual hydrologic modeling, and the inconsistent stationarity assumption in a changing environment. Ensemble forecasting proves to be a powerful tool to represent error growth in the dynamical system and to capture the uncertainties associated with different sources. In practice, the proper interpretation of the predictive uncertainties and model outputs will also have a crucial impact on risk-based decisions. In this study, the performance of evolutionary multi-objective optimization (i.e., non-dominated sorting genetic algorithm II – NSGA-II) as a hydrological ensemble post-processor was tested and compared with a conventional state-of-the-art post-processor, the affine kernel dressing (AKD). Those two methods are theoretically/technically distinct, yet share the same feature in that both of them relax the parametric assumption of the underlying distribution of the data (the streamflow ensemble forecast). Both NSGA-II and AKD post-processors showed efficiency and effectiveness in eliminating forecast biases and maintaining a proper dispersion with increasing forecasting horizons. In addition, the NSGA-II method demonstrated superiority in communicating trade-offs with end-users on which performance aspects to improve.

Abstract. In this paper, we present a custom-designed nuclear magnetic resonance (NMR) platform based on a broadband complementary metal-oxide-semiconductor (CMOS) NMR-on-a-chip transceiver and a synchronous reference signal generator, which features arbitrary phase control of the TX pulse in combination with phase-coherent detection at a non-zero intermediate frequency (IF). Moreover, the presented direct digital synthesis (DDS) based frequency generator enables a digital temperature compensation scheme without the need for additional hardware. NMR spectroscopy and relaxometry measurements verify the functionality of the proposed frequency reference and temperature compensation scheme as well as the overall state-of-the-art performance of the presented system.

Published: February 2022

The implications of COVID-19 on pregnant women are a scarcely researched topic that requires attention. The risks of the disease are a major issue for the pregnant woman and its foetus, requiring a deep and thorough understanding of the conditions that the patients go through after they are infected. This review is a comprehensive study of pregnancy and COVID-19, providing a cognisance of the pathophysiology of the disease on women during pregnancy. It has also summarised the way infection affects the body, acknowledging the changes and effects of a typical female during pregnancy. The study has primarily focused on infection from SARS-CoV-2, and highlighted the infections in contrast to MERS-CoV. The study shows that the infection triggers a cytokine storm in the human body, giving rise to several immune responses that cause changes in immune cells, including leukocytes. The complications thus arise require attention and have been addressed in this study. The lack of unequivocal evidence limits the study to a great extent, making it difficult to draw conclusions; however, notable remarks on prevention and precautionary measures have been entailed in the study. The review concludes by discussing vaccination for pregnancy as a necessary measure going forward.
