Published: August 2022

The article raises the issue of increasing the stability of mixborders by developing additional principles for their formation. Data on the architecture of root systems of perennial plants are presented. Laboratory studies were conducted for the presence of allelopathically active substances in the leaves and root secretions of perennial plants (biotests), the germination of test cultures in various extracts was investigated, more and less active plants were identified. The paper shows the absence of a reliable effect of extracts from the soil as a possible source of accumulated growth inhibitors released by ornamental crops. Keywords: ALLELOPATHY, ALLELOCHEMICALS, MIXBORDER, PERENNIAL PLANTS, LANDSCAPE COMPOSITION

La fertilización del nogal con zinc (Zn) se realiza por aspersión foliar, dado que el nutriente en el suelo se encuentra ligado a los carbonatos, lo que dificulta su absorción por el árbol. Dicha práctica tiene repercusiones ambientales por tratarse de un aerosol. Por ello, el objetivo de este estudio fue generar una alternativa de la aplicación de Zn foliar con Zn quelado edáfico combinado con microorganismos benéficos, para mantener o mejorar la producción de nueces. Se seleccionaron 15 árboles homogéneos con base en el área de sección transversal del tronco y el volumen de la copa en una huerta de nogales en Chihuahua, México. Durante cuatro años (2015-2018), se evaluaron tres tratamientos con cinco repeticiones bajo un diseño completamente aleatorizado. Los tratamientos fueron: 1) Zn foliar (36 % de ZnSO4), 2) Zn edáfico (14 % de Zn quelado con ácidos carboxílicos) y 3) Zn edáfico + hongo micorrízico (Pisolithus tinctorius + Azospirillum brasilense). La huerta estudiada tenía comunidades nativas de P. tinctorius, el cual se encontró en 83.7 % de las raíces analizadas. La producción de nuez, en los cuatro años, con los diferentes tratamientos fue de 27 kg con Zn foliar, 25.4 kg con Zn quelado y 26.9 kg con Zn quelado más microorganismos. Los resultados indican que la aplicación de Zn al suelo es viable y amigable con el ambiente.

Abstract. The Henry's law solubility (HS) and liquid-phase loss rate constants (kl) of the tropospheric trace gas constituents peroxyacetic nitric anhydride (PAN, CH3C(O)O2NO2; commonly known as peroxyacetyl nitrate) and peroxypropionic nitric anhydride (PPN, C2H5C(O)O2NO2; also known as peroxypropionyl nitrate) in deionized (DI) water and of PPN in n-octanol were measured using a flow bubble apparatus at temperatures between 5.0 °C and 25.0 °C. For PAN in DI water, the observed values for HS,aq are consistent with literature, whereas the solubility of PPN in DI water is slightly lower than literature values, ranging from HSCP (PNN)aq =  (1.49±0.05) M atm-1 at 25.0 °C to HSCP (PNN)aq = (7.01±0.25) M atm-1 at 5.0 °C (stated uncertainties are at the 1σ level). The data are best described by ln(HSCP (PAN)aq/[M atm-1]) = -(17.8±0.3) + (5620±85)/T  and ln(HSCP (PNN)aq/[M atm-1]) = -(19.5±1.7) + (5955±480)/T , where T is in Kelvin. For n-octanol, the PPN solubility ranges from HSCP (PNN)oct = (88±5) M atm-1 at 25.0 °C to HSCPoct = (204±16) M atm-1 at 5.0 °C and is best described by ln(HSCP (PNN)oct/[M atm-1]) = -(6.92±0.75) + (3390±320)/T. n-Octanol-water partition coefficients (KOW) for PPN were determined for the first time, ranging from 59±4 at 25.0 °C to 29±3 at 5.0 °C. Observed loss rate constants in DI water are consistent with recent literature and larger than the thermal dissociation rates for both PAN and PPN, consistent with a hydrolysis mechanism, whereas kl values in n-octanol are significantly smaller than gas-phase dissociation rate constants, likely owing to a "cage effect" in the organic liquid. The results imply that uptake of either PAN or PPN on cloud water and organic aerosol is negligible but that uptake of PPN may constitute an overlooked source of peroxy radicals in organic aerosol.

Published: August 2022

Abstract. The management and conservation of lakes should be
conducted in the context of catchments because lakes collect water and
materials from their upstream catchments. Thus, the datasets of catchment-level
characteristics are essential for limnology studies. Lakes are widely spread
on the Tibetan Plateau (TP), with a total lake area exceeding 50 000 km2, accounting for more than half of the total lake area in China.
However, there has been no dataset of lake-catchment characteristics in this
region to date. This study constructed the first dataset of lake-catchment
characteristics for 1525 lakes with areas from 0.2 to 4503 km2 on the
TP. Considering that large lakes block the transport of materials from
upstream to downstream, lake catchments are delineated in two ways: the full
catchment, which refers to the full upstream-contributing area of each lake,
and the inter-lake catchments, which are obtained by excluding the
contributing areas of upstream lakes larger than 0.2 km2 from the full
catchment. There are six categories (i.e., lake body, topography, climate,
land cover/use, soil and geology, and anthropogenic activity) and a total
of 721 attributes in the dataset. Besides multi-year average attributes, the
time series of 16 hydrological and meteorological variables are extracted,
which can be used to drive or validate lumped hydrological models and
machine learning models for hydrological simulation. The dataset
contains fundamental information for analyzing the impact of catchment-level
characteristics on lake properties, which on the one hand, can deepen our
understanding of the drivers of lake environment change, and on the other
hand can be used to predict the water and sediment properties in unsampled
lakes based on limited samples. This provides exciting opportunities for
lake studies in a spatially explicit context and promotes the development of
landscape limnology on the TP. The dataset of lake-catchment characteristics
for the Tibetan Plateau (LCC-TP v1.0) is accessible at the National Tibetan
Plateau/Third Pole Environment Data Center

Modeling the role of livestock grazing in C and N cycling in grasslands with LPJmL5.0-grazing
Authors: Heinke Jens , Rolinski Susanne , Müller Christoph
Published: August 2022

Abstract. Grazing livestock alter the fluxes of carbon (C) and nitrogen (N) in grasslands. We implement a livestock module representing grazing dairy cows into LPJmL5.0-tillage, a global vegetation and crop model with explicit representation of managed grasslands and pastures, forming LPJmL5.0-grazing. The new module explicitly accounts for feed quality on dry matter intake and feed digestibility using relationships derived from compositional analyses for different forages. Partitioning of N into milk, feces, and urine are simulated by the new livestock module shows very good agreement with observation-based relationships reported in the literature. Modeled C and N dynamics depend on feed quality (C:N ratios in grazed biomass), feed quantity, livestock densities, manure or fertilizer inputs, soil, atmospheric CO2 concentrations, and climate conditions. Due to the many interacting relationships, C sequestration or emission rates as well as N losses and N use efficiency (NUE) show substantial variation in space and across livestock densities. The improved LPJmL5.0-grazing model can now assess the effects of management and climate change on grazing dairy productivity, C dynamics and N losses. Optimal stocking densities can be derived per location for different optimization targets, such as maximization of milk production, lowest emission intensity, best NUE, or highest C sequestration.
A comparative study of the unscented Kalman filter and particle filter estimation methods for the measurement of the road adhesion coefficient
Authors: Qi Gengxin , Fan Xiaobin , Li Hao
Published: August 2022

Abstract. The measurement of the road adhesion coefficient is of great
significance for the vehicle active safety control system and is one of the key
technologies for future autonomous driving. With a focus on the problems of
interference uncertainty and system nonlinearity in the estimation of the road
adhesion coefficient, this work adopts a vehicle
model with 7 degrees of freedom (7-DOF) and the Dugoff tire model and uses these models to estimate the road adhesion
coefficient in real time based on the particle filter (PF) algorithm. The
estimations using the PF algorithm are verified by selecting typical
working conditions, and they are compared with estimations using the unscented
Kalman filter (UKF) algorithm. Simulation results show that the road adhesion
coefficient estimator error based on the UKF algorithm is less than 7 %, whereas the road adhesion coefficient estimator error based on the PF algorithm is
less than 0.1 %. Thus, compared with the UKF algorithm, the
PF algorithm has a higher accuracy and control effect with respect to
estimating the road adhesion coefficient under different road conditions. In order to
verify the robustness of the road adhesion coefficient estimator, an
automobile test platform based on a four-wheel-hub-motor car is built.
According to the experimental results, the estimator based on the PF algorithm
can realize the road surface identification with an error of less than 1 %,
which verifies the feasibility and effectiveness of the algorithm with respect to
estimating the road adhesion coefficient and shows good robustness.
Critical World-Systems Analysis
Authors: Grell-Brisk Marilyn
Published: August 2022

From the first #BlackLivesMatter (#BLM) in 2013 to the summer of 2020, America and the rest of the world have been compelled, at minimum, to pay attention to the continuous rejection of Black being(ness). Black Lives Matter! isn’t just a call to attend to police brutality against Black people in America, it is a rallying call demanding that Black folx’s humanity be acknowledged and accorded without question—that we be seen. It is a declaration of resistance against the antiblackness that is embedded within racial capitalism. And, it is a demand that comes from years of frustration from Black lives being continuously and violently disregarded, of seeing “Black faces in high places” but no tangible institutional relief from the ever-present abjection of Blackness and Black folx. I argue that to pre-figure Black futurity, the movement for Black lives must necessarily be a movement that actively calls attention to and resists disposability regimes that highlight the tension between the world-system’s economics of inequality and its professed politics of equality. I contend that the active rejection of antiblackness and the movement for Black lives must be transnational in scope, and while implicitly occupying non-state anti-systemic spaces, it must reimagine the logics of solidarity, simultaneously embodying Black transnational and translocal collaboration; it must be radical in scope, seeking not simply to fix the existing structures of inequality and oppression but envision new structures, a complete reorganization of society where antiblackness no longer exists. To begin the work, I propose a multilevel analytical framework.
Maroon Movements Against Empire
Authors: Eddins Crystal
Published: August 2022

Marronnage, or escape from slavery, was a longue-durée form of resistance to slavery in Haiti and was also, as Sylvia Wynter argues, a “dialectical response to the capitalist plantation system”—a system that aimed to deny humanity, sever social and cultural ties, and commodified people and their labor power. This article, as well as works by others such as Cedric Robinson (1983), Sylvia Wynter (n.d.), and Jean Casimir (2020), argues that marronnage was a fundamentally anti-capitalist mode of resistance, socio-political critique, and grassroots mobilizing. In the immediate moments when enslaved people fled plantations, they reclaimed possession of themselves and other tangible and intangible resources, such as their time, social relationships, forms of knowledge, and labor skills that enslavers stole from them. When maroons re-appropriated resources and mobilized themselves, they challenged and subverted colonial plantation structures, contributing to the downfall of both Spanish and French imperial slaveries in Haiti. During and after the Haitian Revolution of 1791–1804, Africa-born rebels and maroons were central to the mobilizing structures that successfully fought to abolish slavery and overturn colonialism—representing an astounding rupture to the prevailing Atlantic world-system that was dependent upon enslaved labor. Even after the post-independence Haitian government replicated aspects of the colonial administration, as Casimir (2020) points out, the formerly enslaved masses of Haiti organized themselves into communal social arrangements that prioritized subsistence labor and extended kin networks, and continued to rely on marronnage to protest exploitative economic practices. This article explores the trajectory of marronnage in Haiti as a continuous struggle, emphasizing the ways that it exposed the violence, exploitation, and oppression inherently embedded in the Atlantic world-system, and exposed the limits of the governing Haitian states.
Analysis and Simulation of Overmodulation Modes of a Three-Inverter Block of the Photovoltaic Installation
Authors:   Institute of Power Engineering of Moldova, Oleschuk V.
Published: August 2022

The purpose of this work is to modernize the control scheme of a transformer-based photovoltaic system with three inverters controlled by the modified algorithms of synchronous spacevector PWM in order to ensure linear regulation of the system in the overmodulation zone of the inverter block in the process of forming a symmetrical and synchronized (with the operating frequency of the system) voltage on the inverter-side windings of a power transformer. This goal is achieved by the fact that the process of two-stage control of the system in the zone of overmodulation of inverters is carried out on the basis of synchronized phase shifts between the control signals of inverters (a constant phase shift, as well as an additional adjustable phase shift between the inverter signals as a function of the duration of clock subintervals), with an appropriate modification of the algorithms of synchronous PWM of inverters due to the inclusion of two specialized correction factors in the basic functional dependencies. The most significant results of the work include the fact that in a system with a modified control scheme and modulation of the inverter block in the overmodulation zone, the resulting voltage on the inverter-side windings of the power transformer is characterized by quarterwave symmetry, and its spectrum contains no even-order harmonics, as well as subharmonics, including regimes of fluctuations in the operating frequency of the system connected to a three-phase network, thereby helping to reduce losses in the transformer windings and improve the efficiency of photovoltaic systems.

Energy prices and сost of materials for solar and wind power plants have increased over the past year. Therefore, significance increases for the hydropower and long-term (1–10 years) planning generation for the existing hydropower plants, which requires forecasting the average monthly values of the river flow. This task is especially urgent for countries without their own oil-fields and opportunity to invest in the creation of solar or wind power plants. The aim of the research is to decrease the mean absolute forecasting error of the long-term prediction for the Vakhsh River flow (Tajikistan) based on the long-term observations. A study of existing methods for the river runoff forecasting in relation to the object under consideration was carried out, and a new transformation model for the space of the input features was developed. The most significant results are the decrease in the average forecast error in the Vakhsh river flow achieved by the use of the proposed space of polynomial logarithmic features in comparison with other methods, and the need to use at least the 20 year-old observational data for the long-term operation planning of the hydropower plants and cascades of the hydropower plants obtained from the results of computational experiments. The significance of the results lies in the fact that a new approach to the long-term forecasting of river flow has been proposed and verified using the long-term observations. This approach does not require the use of the long-term meteorological forecasts, which are not possible to obtain with high accuracy for all regions.

Published: August 2022

Xiphodynia is a rare but debilitating condition that can be described as a form of pain on the xiphisternal joint or any related structures that are anchored to the xiphoid process. Although xiphodynia is a musculoskeletal pain in nature, the pain located in the anterior chest can commonly mislead physicians into pursuing other diagnoses such as cardiac diseases. This leads to a prolonged duration of pain before receiving treatment. In the attempt to alleviate pain resulting from this condition, physicians have previously utilized a range of treatment options, including conservative management, injections, or in severe cases, xiphoidectomy. In this review, we aim to give a brief overview of xiphodynia, including clinical diagnoses and current treatment modalities.

Key Summary Points

1. Xiphodynia can be described as pain radiating from an irritated xiphoid process that can travel to the chest, abdomen, throat, and arms

2. Risk factors for developing secondary xiphoidalgia include GERD, gall-bladder disease, angina pectoris, and coronary-artery disease

3. The treatment of xiphodynia can range from conservative management to injections or a xiphoidectomy

4. Further research is required to develop a standardized treatment protocol and currently the choice of treatment depends on the patient’s individual case and the degree of severity

This article analyzes the document and literature relating to civil aviation safety in Indonesia. The commercial airlines has rapidly growth since the government stipulated the open air policy in 2000s. However, the fatal rate accident of aviation simultanously had recently and it made Indonesian airlines were banned by the European Union in 2007. Safety performance of Indonesian civil aviation has been concerned since then. Using international regime approach to assess the country's aviation performance based on the principle of International Civic Aviation Organization (ICAO), this study reveals that although generally the aviation management had already met the standard requirements, there are still several aspects that should be considered as drawbacks that might implicated the fatally accident in the future. This article found the parallel result of reexamination of aviation accident caused by human factor is related to the profile of accident rate toward the safety compliance indicator using International regime of ICAO. The article finally provides some recommendations: increasing safety compliance index and surveillance on the safety obligation, and an aviation policy restoration that includes safety and security components into a synergetic regulation package to achieve a proper safetytiness of Indonesian civic aviation.

Descriptive statistics, such as frequencies and means, were used to explain the learning style scores and gender of the respondents. An independent T-test was used to compare the differences between genders. The result shows that theoretical style (mean = 3.83) was rated the highest by the students. This was followed by the pragmatic style (mean=3.81) and the reflective style (mean=3.79). Students rated the activist style as moderate (mean=3.46). The independent T-test showed that there was no significant difference between genders.
Innovation Strategies and Corporate Performance: Perspective from India
Authors:   Anna University, India, Manji Dhruv A.
Published: August 2022

More studies indicate that businesses becomes very competitive in an emerging market when they give importance to innovative activities that build their reputation in the market environment. Essentially, the key reason for innovativeness is the desire of firms to obtain increased business corporate performance and increased competitive edge and the ultimate goal of innovation is to improve business corporate performance. Innovation strategies are critical for firms that are in pursuit of improved corporate performance and their reward is often an increase in their profits and their market share. Process of strategic innovation is strongly associated with organizational learning and refers to ability of organization to generate, accept and implement new ideas, processes, products or services. The primary goal of process innovation is to generate a notable increase in corporate performance or to drive down costs significantly. This approach can help organizations achieve major reductions in process cost, improvements in quality, service levels and other business objectives. Strategic innovation is contributor to creation of new markets and products for the market, however even after the benefits of strategic innovation has been established the impact of strategic innovation on corporate performance of Businesses has remained misunderstood.

The simplest definition of phycoremediation is the use of algae to treat wastewater. Water as a commodity is very scarce and follows a downward trend with every passing day. The Middle East and North Africa region accommodates almost 5% of the world’s population but contain less than 1% of the world’s annual renewable freshwater. The cities are growing at a rate of 4% every year, so this is only going to worsen the demand and supply of water. Hence the use of algae (microalgae and marine macroalgae, commonly known as seaweeds) particularly microalgae can help treat the water efficiently and cater to the demand of the growing population. The omnipotent stature of algae and their adaptation to multifarious habitats makes them tolerant to a wide range of environmental conditions, including nutrient levels. The algae can work as a carbon-reducing system that can convert carbon dioxide into oxygen through photosynthesis, due to its handling of adverse conditions we can use microalgae for bioremediation of wastewater and the biomass produced during the process can serve as food, fertilizers, and late, biofuels.

In the field of hydraulic machines, piston pumps are the only ones that can work under very high pressures and deliver the best efficiency as a result of which they have a very sophisticated design. As per surveys, most parts of these pumps have validation from the experience of designers as a result of which there isn’t any mathematical tool for design optimization of different parts. Although there are now companies e.g. Oilgear Towler, who are in favor of, and themselves inserted, slots (grooves) on the slippers and in pistons as we shall in this report, there is no particular study to realize their benefits and drawbacks. Therefore, it is necessary to study the advantages and disadvantages arising due to the presence of grooves on the surface of different parts of the pump mathematically or through CFD solvers. In this project work, the aim is to analyze the effect of design parameters and working conditions on the pump behavior. This is done using a parametric study performed on a model of the slipper and simulating the physical problem on ANSYS. As major leakage occurs between slipper and swash plate clearance there-fore in this project report static and dynamic analysis of slipper is done. The Navier Stokes Equations are solved in 3-D to acquire results using Rhie and chow method and ANSYS FLUENT solver. The various design points which affect the efficiencies of a pump in a positive manner, if any, shall be discussed in the conclusion part.

Concrete is the more widely utilized construction material on the planet earth, particularly in evolving and developing nations. Concrete was created as a stronger and more resistant building material as it was worked upon over time. Gradually, the man figured out how to create it, transport it, and utilize it more efficiently. We know that concrete is made from cement, sand, aggregate, and water. Out of these, some of them may be replaced with some other material like wheat straw ash, rice husk ash, fly ash, etc. for various purposes, mostly to utilize waste material without affecting the important properties of concrete beyond acceptable limits. This study deals with an investigation into the properties of concrete by partial replacement of sand with wheat straw ash and the addition of polypropylene fiber in it. Wheat Straw is the portion of leftovers of the wheat crop after it is harvested. In most countries, it is a waste. People burn it and cause pollution and health hazards, good strength and high performance in concrete are very much required in future construction work. It is felt that fiber dispersion in concrete is one method to improve the structural characteristics of concrete.
