К настоящему времени накоплен большой объём калориметрических данных о теплоте (энергии) взрыва Q различных взрывчатых веществ (ВВ) и взрывчатых составов (ВС). Получены зависимости Q от начальной плотности ВВ Q(ρ0). Однако, на практике давление детонации в основном заряде можно менять, вызывая пересжатую детонацию, за счёт инициирования основного заряда мощным ВВ, поэтому практический интерес представляют зависимости теплоты взрыва от давления детонации Q(Р), которые можно получить на основе имеющихся зависимостей Q(ρ0) для индивидуальных ВВ, распространив их на ВС. Приведена методика определения зависимостей для расчёта теплоты взрыва различных ВС, включая алюминийсодержащие, как при нормальной так и при пересжатой детонации

A large volume of calorimetric data on the heat energy Q of explosion for various explosives (Es) and explosive compositions (EC) has been accumulated by now. The dependences of Q on the initial ES density Q (ρ0) are obtained. However, the detonation pressure in the base charge can be changed in practice causing super compressed detonation, due to the initiation of the base charge by a powerful explosive; therefore, the dependences of the explosion heat on the detonation pressure Q (P), which can be obtained on the basis of the available dependences Q (ρ0) for individual explosives is of practical interest as they can be applied to EC. A method to determine the dependences for calculating the heat of explosion of various aircraft, including aluminum-containing ones, both during normal and super compressed detonation is presented.

В рутиле были определены примеси W6+, Nb5+, Fe3+, V3+ и Cr3+. Установлена прямая корреляция концентрации в рутиле W6+ и Nb5+ с суммой трехвалентных катионов, предложены следующие схемы изоморфного замещения: 3Ti4+ = W6+ + 2Me3+, 2Ti4+ = Nb5+ + Me3+. В ряде анализов рутила отмечается избыток трехвалентных катионов, не скомпенсированных высоковалентными примесями. Избыток трехвалентных катионов объясняется появлением в структуре анионных вакансий по схеме 2Ti4+ + O2– = 2Me3+ + [vac]. Данное предположение подтверждается дефицитом кислорода в ряде кристаллохимических формул рутила.

Published: November 2021

Due to their availability, low cost, non-toxicity and tunability, polymeric carbon nitrides (CNx) represent one of the most attractive materials classes for the development of fully sustainable photo(electro)catalytic systems for solar-driven water splitting. However, the development of CNx-based photoanodes for visible light-driven water oxidation to dioxygen is rather challenging, particularly due to issues related to photoelectrode stability and effective coupling of the light absorber with water oxidation catalysts. Herein, a triadic photoanode comprising a porous TiO2 electron collector scaffold sensitized by CNx coupled to a molecular cobalt polyoxometalate (CoPOM = [Co4(H2O)2(PW9O34)2]10─) catalyst is reported. Complete water oxidation to dioxygen under visible (λ > 420 nm) light irradiation is demonstrated, with photocurrents down to relatively low bias potentials (0.2 V vs. RHE). Furthermore, polyethyleneimine (PEI), a cationic polymer is shown to act as an effective and non-sacrificial electrostatic linker for immobilization of the anionic CoPOM onto the negatively charged surface of CNx. The optimized deposition of CoPOM using the PEI linker translates directly into improved efficiency of the transfer of photogenerated holes to water molecules and to enhanced oxygen evolution. This work thus provides important design rules for effective immobilization of POM-based catalysts into soft-matter photoelectrocatalytic architectures for light-driven water oxidation.
Enantioselective Au(I)-Catalyzed Multicomponent Annulation via Tethered Counterion-Directed Catalysis
Authors: Zhang Zhenhao , Sabat Nazarii , Frison Gilles , Marinetti Angela , GUINCHARD Xavier
Published: November 2021

Gold(I) complexes of a new chiral phosphoric acid functionalized phosphine of the CPA-Phos series enable the enantioselective multicomponent reactions between aldehydes, hydroxylamines and cyclic yne-enones, leading to 3,4-dihydro-1H-furo[3,4-d][1,2]oxazines. This represents the first example of highly enantioselective multicomponent reaction in gold(I) catalysis. The reactions proceed at low catalyst loading, provide high yields, total diastereoselectivity and enantiomeric excesses up to 99%. Silver-free conditions can be applied. The method has a very broad scope, as it applies to both aliphatic and aromatic aldehydes and hydroxylamines, to a variety of cyclic yne-enones, as well as to yne-enone derived oximes. DFT calculations are reported that enlighten the enantiocontrol pathway.

Authors: Klingler Sarah , Hniopek Julian , Stach Robert , Schmitt Michael , Popp Jürgen , Mizaikoff Boris
Published: November 2021

Scientific questions in fields such as catalysis, monitoring of biological processes or environmental chemistry demand for analytical technologies combining orthogonal spectroscopies. Combined spectroscopic concepts facilitate in-situ on-line monitoring of dynamic processes providing for a better understanding of the involved reaction pathways. In the present study, a low-liquid-volume multi-spectroscopic platform was developed based on infrared attenuated total reflection (IR-ATR) spectroscopy combined with Raman spectroscopy and lumines-cence sensing. For demonstrating the measurement capabilities, exemplary analyte systems including water / heavy water and aqueous solutions of ammonium sulfate were analyzed as proof-of-principle studies. It was successfully demonstrated that three optical techniques may be integrated into a single analytical platform with-out interference providing synchronized and complementary datasets by probing the same minute sample vol-ume. In addition, the developed assembly provides a gas-tight lid sealing the headspace above the probed liq-uid for monitoring the concentration of molecular oxygen also in the gas phase via luminescence quenching. Hence, the entire assembly may be operated at inert conditions, as required for example during the analysis of photocatalytic processes.
High harmonic spectra computed using time-dependent Kohn-Sham theory with Gaussian orbitals and a complex absorbing potential
Authors: Zhu Ying , Herbert John
Published: November 2021

High harmonic spectra for H2 are simulated by solving the time-dependent Kohn-Sham equation in the presence of a strong laser field, using an atom-centered Gaussian representation of the orbitals and a complex absorbing potential to mitigate artifacts associated with the finite extent of the basis functions, such as spurious reflection of the outgoing electronic wave packet. Interference between the outgoing and reflected waves manifests in the Fourier transform of the time-dependent dipole moment function and leads to peak broadening in the high harmonic spectrum as well as the appearance of spurious peaks at energies well above the cutoff energy at which the harmonic progression is expected terminate. We demonstrate that well-resolved spectra can be obtained through the use of an atom-centered absorbing potential. As compared to grid-based algorithms for solving the time-dependent Kohn-Sham equations, the present approach is more readily extendible to larger polyatomic molecules.
A Mathematical Model for Covalent Proteolysis Targeting Chimeras: Thermodynamics and Kinetics underlying Catalytic Efficiency
Authors: Chaudhry Charu
Published: November 2021

Proteolysis targeting chimeras (PROTACs), heterobifunctional protein degraders, have emerged as an exciting and transformative technology in chemical biology and drug discovery to degrade disease-causing proteins through co-opting of the ubiquitin-proteosome system (UPS). Here we develop a mechanistic mathematical model for the use of irreversible covalent chemistry in targeted protein degradation (TPD), either to the target protein of interest (POI) or E3 ligase ligand, considering the thermodynamic and kinetic factors governing ternary complex formation, ubiquitination, and degradation through the UPS. We highlight key advantages of covalency to POI and E3 ligase, and the underlying theoretical basis in the TPD reaction framework. We further identify regimes where covalency can serve to overcome weak binary binding affinities and improve kinetics of ternary complex formation and degradation. Our results highlight the enhanced catalytic efficiency of covalent E3 PROTACs and thus their potential to improve the degradation of fast turnover targets.

Authors: Iqbal Muhamad
Published: November 2021

Tax revenues until the end of 2019 amounted to IDR 1.545,3 trillion, however, the level of compliance in terms of reporting taxes is still low, ranging from 60% to 70% and dominated by individual employee taxpayers. The lack of awareness of taxpayers in Indonesia is seen in the tax ratio percentage below 15% in the last five years. Tax knowledge is an important aspect in increasing compliance, considering that in the current digital era, the process of registering and paying taxes will always experience changes in terms of systems and procedures for implementing them. This can also form a perception for taxpayers on the payment system that is part of the Modul Penerimaan Generasi Ketiga (MPN-G3). This research uses descriptive and verification methods. The sample size is 100 respondents who are individual taxpayers, entrepreneurs or non-employees who are registered at KPP Pratama Karawang Utara. The analysis used in this research is scale range analysis and path analysis. Based on the research results, knowledge of taxation has a direct effect on individual taxpayer compliance and does not have an indirect effect through taxpayer awareness. Taxpayers' perception has a direct effect on taxpayer compliance and does not have an indirect effect through mandatory awareness

Published: November 2021

The scelionid parasitoid Trissolcus basalis (Wollaston,1858) has been detected in Belgium for the first time based on specimens reared from a parasitized egg mass of Nezara viridula (Linnaeus,1758) collected in an urban garden at Sint-Amandsberg, Ghent. Identification was based on adult morphology and DNA barcoding. This is presently believed to be the northernmost record in Europe of T. basalis and could be the consequence of a northward expansion of this species due to climate change. This first record may be of economic importance for the biological control of stink bug pests in Belgian vegetable and fruit production.
A review on the potential of empty fruit bunch (EFB) compost as growing
medium for oil palm seedling production
Authors: Zakri N.A. , Adam S.
Published: November 2021

The oil palm industry is among the important sectors in Malaysia. The productions of
palm oil keep increasing year by year due to high demand from other countries,
generating an abundance of wastes from the field and the mill. These wastes may
significantly affect the environment. Composting is one of the methods to reduce the
volume of waste. The compost material is widely used especially in agriculture
activities due to its properties which have been enhanced during the composting
process. Empty fruit bunch (EFB) compost mostly returns to the soil as mulch to
conserve soil moisture and acts as organic fertilizer since it contains high nutrients
needed by the plant. Currently, the depletion of fertile soil leads to less availability of
growing medium, especially in the nursery. The properties of the growing medium are
important to ensure better root development of seedlings and subsequently affect the
overall plant growth. Therefore, numerous studies have been conducted to identify the
suitable growing medium as a substitute for topsoil which is currently limited to raising
seedlings in the nursery. This review examines the current methods of composting EFB
and provides summarized research information on the effect of EFB compost on oil
palm seedling growth. The oil palm wastes that are properly managed could produce
value-added by-products and promotes sustainable agriculture practices.

Published: November 2021

Melastoma malabathricum and Chromolaena odorata are classified under broad-leaved
weeds that are widely spread in the open land area. Melastoma malabathricum is
commonly known as ‘‘senduduk’’, and C. odorata is locally known as “Pokok Kapal
Terbang”. Both weeds are categorized as potential weeds as they have high nutritive value
and are rich in chemical compounds. This study aimed to determine their chemical
constituents and possible potential for antioxidant activity as these weeds have been
reported to possess antioxidant properties. Screening of the plants was performed using
standard methods and revealed the existence of various secondary metabolites such as
saponins, terpenoids, phenols, tannins, and flavonoids of both weed extracts. Antioxidant
activity was validated by the DPPH radical scavenging assay of M. malabathricum and C.
odorata crude ethanol extract. The IC50 values for the percentage radical scavenging
effects for the extracts were determined. The IC50 value of M. malabatrichum extract was
81.116 μg/mL, C. odorata was 312.903 μg/mL, Vitamin C was 31.023 μg/mL and BHA
was 71.521 μg/mL respectively. The study showed that the antioxidant activity of M.
malabatrichum was more potent and better than C. odorata.
COVID-19 and food security in Malaysia: implications on smallholding
agriculture
Authors: M.N.H. Rashidi , Abdul Fatah F. , Saili A.R.
Published: November 2021

Over the last two decades, the world has been confronted with several outbreaks of
infectious diseases. Ebola, influenza A (H1N1), SARS, MERS, Zika and most recently,
COVID-19, have had a serious global impact on economic instability, local and global
public resources and above all, people's health. As the effect of COVID-19 is significant
to the world market, it has also indirectly impacted the agricultural sector and hence has
significantly exposed the strengths and limitations of the farming systems in terms of
resiliency, production and food security which offers important lessons for policymakers.
Hence, this study was conducted to analyse the impact of COVID-19 pandemics on the
agricultural industry especially the smallholders who are more vulnerable during or postpandemic due to the lack of resilient supply networks, low periphery of market access and
limited production. In doing so, a survey was conducted, which began in May 2020,
consisting of online questions that contain information about the impact of COVID-19 on
the smallholding sector and the challenges faced by smallholders including crops,
livestock, fisheries and aquaculture in Malaysia. A total sample of 217 smallholders or
farmers from several states in Peninsular Malaysia was obtained within the Movement
Control Order (MCO) period and later extended to the Conditional MCO (CMCO).
Almost 86% of respondents answered that COVID-19 had heavily affected agriculturerelated activities in Malaysia. Using a principal component analysis, our findings reveal
four major issues or challenges those farmers faced during the MCO/CMCO namely
income, uncertainties of supply and price, logistics and marketing activities.
Optimization of selected plant growth regulators on callus induction of Oryza

Authors: H. Siti Nur Adila , Y. Nor Azma
Published: November 2021

MR 219, an indica rice from a cross between MR 137 and MR 151 is a long-grain rice
variety of high-yielding, good quality of shape and taste, short maturation as well as
resistance to blast and bacterial leaf blight. However, it is regarded as a recalcitrant variety
due to its low ratio of callogenesis and regeneration in in vitro culturing. This would be a
hindrance to crop improvements such as genetic transformation and other crop
improvement methods. The objective of this study was to optimize the concentrations and
combinations of plant growth regulators (PGRs) which were 2,4-Dichlorophenoxyacetic
acid (2,4-D), Kinetin (KIN) and Naphthalene acetic acid (NAA) on its callus induction
that ranging from 0.5 to 15.0 mg/L. The callus was induced from the mature seeds of MR
219 on the Murashige and Skoog (MS) media supplemented with 4.4 g/L of MS powder
with vitamins, 30.0 g/L of sucrose and 3.5 g/L of gelrite with the addition of 2,4-D, KIN
and NAA in different concentrations and combinations. All media supplemented with 2,4-
D had successfully induced the callus and 2.0 mg/L of 2,4-D was the best concentration
for the callus induction with a 100% success rate. The addition of 15.0 mg/L of NAA,
provided less time taken for callus induction with better callus morphology which resulted
in fewer browning problems.

Published: November 2021

The world faces many large-scale risks. We describe these global catastrophic and existential risks and identify some challenges in governing the prevention and mitigation of such risks. We identify that risk reduction activity in Aotearoa New Zealand has not appropriately addressed these threats. On the basis of the challenges identified, we then deduce the desired features and functions of an entity for effectively governing risk reduction approaches. We argue for an entity that is: anticipatory, central/aggregating, coordinating, apolitical, transparent, adaptive and accountable. We offer structural options for such an entity and outline the merits of several options.

Identification of risk factors associated with national transmission and late presentation of HIV-1, Denmark, 2009 to 2017
Authors: van Wijhe Maarten , Fischer Thea K , Fonager Jannik
Published: November 2021

Background

Despite availability of pre-exposure prophylaxis (PrEP), the incidence of HIV-1 in Europe remained stable the past decade. Reduction of new HIV-1 infections requires more knowledge about the profiles of high-risk transmitters and late presenters (LP).

Aim

We aimed to investigate risk factors associated with HIV-1 transmission clusters and late presentation with HIV-1 in Denmark.

Methods

Blood samples and epidemiological information were collected from newly diagnosed HIV-1 patients between 2009 and 2017. We genotyped pol genes and performed phylogenetic analyses to identify clusters. Risk factors for clustering and LP were investigated with partial proportional odds and logistic regression. Covariates included transmission mode, HIV-1 subtype, age, origin and cluster activity.

Results

We included 1,040 individuals in the analysis, 59.6% identified with subtype B and 48.4% in a cluster. Risk factors for clustering included Danish origin (odds ratio (OR): 2.95; 95% confidence interval (CI): 2.21–3.96), non-LP (OR: 1.44; 95% CI: 1.12–1.86), and men who have sex with men (MSM). Increasing age and non-B subtype infection decreased risk (OR: 0.69; 95% CI: 0.50–0.94). Risk for late presentation was lower for active clusters (OR: 0.60; 95% CI: 0.44–0.82) and Danish origin (OR: 0.43; 95% CI: 0.27–0.67). Non-Danish MSM had a lower risk than non-Danish heterosexuals (OR: 0.34; 95% CI: 0.21–0.55).

Conclusion

HIV-1 transmission in Denmark is driven by early diagnosed, young, subtype B infected MSM. These may benefit most from PrEP. Non-Danish heterosexual HIV-1 patients could benefit from improved communication to achieve earlier diagnosis and treatment.
GEOPOLITICAL CASES IN THE PROCESS OF SETTLEMENT OF THE TRANSNISTRIAN CONFLICT

The article analyzes the features of the involvement of external actors in the process of resolving the Transnistrian conflict. The authors made an excursion to the genesis of registration of the regional system of relations, which revealed the specifics of the national interests of the world’s leading players in the region. The article also analyzes competition of geopolitical in- terests in the region, representing by its nature the reflection of the transform- ing basics of modern world order. Despite the term of Euro-Atlantic solidarity established in the scientific community, however, it is impossible to talk on the agreed position of the European and North American communities in ap- proaches to regional processes. The nature of the settlement of the Transnistri- an relations reflects an incomplete coincidence of the positions of the European Union and the United States in the process of resolving the conflict . At the same time, attempts to resolve the conflict bring to the surface the Romanian factor which every year is growing and exerting a great influence on Moldova both in the trade and economic sphere and in the political one. The authors mark a special place of the Russian Federation in the regional system of rela- tions.

Published: November 2021

Although researchers have studied the contribution of diagrams to learning mathematics based on various perspectives, the meta-analysis of relevant studies is lacking. The purpose of this study is to advance the discussion of epistemological assumptions underlying various approaches to the relationship between diagrams and mathematics learning. To this end, we reviewed theoretical and empirical studies about the contribution of diagrams in mathematics learning, focusing on how they account for the relationship between diagrams as signs and mathematics. The review has led to a proposed framework that categorizes the perspectives on diagrams as signs in pertinent research into structure-based, context-based, and material-based perspectives. We further identified differences in the epistemological background upon which studies from the three perspectives are based and the way the perspectives describe the relationship between diagrams and mathematics learning. The framework was useful identifying the multidimensionality of mathematics learning related to diagrams as well as the use of theoretical lenses by researchers depending on specific aspects of mathematics learning.

Published: November 2021

Patchouli (Pogostemon cablin Benth.) plant is one of the essential oil producing plants, that is useful in the chemical industry as a raw material for fragrance products and in the pharmaceutical field. The success rate of patchouli early growth, is largely determined by the cultivation techniques used, including the use of growth regulators, and growing media. This study aims to determine the effect of IBA growth regulators and the composition of plant media on the growth of patchouli plants. This research is carried out in the Greenhouse of the Forestry Study Program of the University of Mataram, using a Factorial Completely Randomized Design (RALF), the first factor is IBA growth regulator with 3 levels, namely 0, 20, 25 ppm and the second factor is composition of plant media with 3 levels, namely forest soil media, soil media:sand:compost (1:1:1), and soil media:sand:compost (2:1:3). The results show that the effect of IBA significantly affect the success percentage of cuttings and the number of roots of patchouli plants. The effect of plant media composition and the interaction between treatment of IBA with plant media composition did not have a significant effect on the growth parameters of patchouli plants.
Fear the Walking Dead? Incidence and Effects of Zombie Firms in Europe
Authors: Hallak Issam , Harasztosi Péter , Schich Sebastian
Published: November 2021

One explanation for the observed lack of economic dynamism in Europe is that so-called zombie firms are spreading and that they crowd out the growth of other, potentially more “lively”, companies. Zombie firms are firms that apparently are unable to repay their debt and yet, they continue operating. The report describes estimates for 2010 and 2013 of the incidence of zombie firms across 19 European countries using firm-level data for more than one million companies. Importantly, it uses three alternative definitions of what constitutes a zombie firm to ensure robustness of estimates. The report finds that zombie firms are spreading in Europe, with the estimated incidence for 2013 being higher than for 2010. It also identifies considerable differences across countries. Zombie firm shares as of overall corporate capital are particularly high in Greece and Spain, but low in the Czech Republic and Slovakia. Distinguish among firms in terms of size and age, the report finds that larger and older firms, as compared to relatively smaller and younger firms, are more likely to be zombie firms. The report also finds that the growth of zombie firms in terms of employment crowds out the growth of other, non-zombie firms, especially young ones. Thus, one policy implication is that, greater economic activity is achieved by allowing zombie firms to exit the market.

The economic profitability of cereal production systems in the context of adaptation to climate change: the case of millet
Authors: OUMAROU DAN-BAKI Abdoul Azizou , TARNO Mamane
Published: November 2021

This article studies the economic profitability of the millet production in a context of adaptation to climatic changes by considering the techniques of adaptation to soil protection, namely, low wall girdles tree and half-moon in order to determine their impact on the economic profitability of the production of this cereal.The economic model of profitability developed by Gnanglé and al. [15] is used to analyze this effect. The data used in this paper is obtained from the ministry of agriculture of Niger (ECVM/A 2015) and consists of 3,985 households from two regions of Niger, namely, the Maradi and Diffa regions. The results show that the techniques of "belt of tree" and "half-moon" increase the economic profitability of the millet production and that the effects are, respectively, 0.19 and 0.054 in the two areas. The econometric results show that these techniques are profitable in both areas. Given the effectiveness of these techniques, this study suggests that producers increase these practices in order to mitigate the effects of climate change on the millet production in Niger. Lastly, the government must popularize these techniques and support their use for a better adaptation of agriculture in these zones to climate change.
Management of air pollution by a system of transferable individual emission permits with overlapping generations.
Authors: Adamou TCHOUSSO
Published: November 2021

The purpose of this article is to analyze the effectiveness of a pollution management system through individual permits that are distributed to young people with overlapping generations. From a general equilibrium model, the results show that such a system provides the conditions for optimal pollution management. But because of the non-cooperative behavior of the actors, this policy cannot institute intergenerational altruism. Incentives such as tax or subsidy are needed to get the receiving population to better choose between the physical good whose production satisfies their needs and the quality of the environment that depends on their option to sell the permits to firms or the future generation.

Departing from the covid-19 pandemic that is hitting humans today, all sectors of life seem to be experiencing shocks, especially education. The learning process that should be carried out directly between teachers and students, has now been transferred to an online system. The existence of major changes in the current education system has forced teachers to mobilize all their potential as educators by teaching using technology. Especially faith education, teachers are required to be able to provide faith education to their students as in face-to-face learning in the past. This is of course a new responsibility for teachers. However, in this limited condition, the teacher's work will be greatly helped by the support from the parents who are always by their children's side. It is a joint task between teachers and parents in optimizing the process of creed education for students.Keywords: Creed, Technology, and Pandemic
QUE FAÇO COM MEU DINHEIRO? VIABILIDADE ECONÔMICA EM ALOJAR FRANGOS AO INVÉS DE PERUS
Authors: Godgienski da Silva Carla , Sampaio Alves Danieli Taís , Dagostini Luciane
Published: November 2021

A pesquisa tem como objetivo analisar a viabilidade econômica entre alojar frangos em aviário que antes alojava perus. O ambiente de estudo constituiu-se de duas propriedades rurais que desenvolvem também a atividade avícola de criação de aves de corte, na região Sudoeste do Paraná. As duas propriedades possuem parceria com a mesma integradora. Foi realizada por meio de estudo de caso, pesquisa documental e abordagem qualitativa e quantitativa. Também foi feita projeção e análise dos dados, os mesmos foram submetidos com utilização do payback para apurar o retorno do investimento. Considerando-se que na mudança de alojamento de perus para frangos, será aproveitada a estrutura do barracão e alguns equipamentos, mas se faz necessário adaptar parte do aviário e adquirir equipamentos. O retorno esperado do investimento é de aproximadamente 54 meses, conclui-se que pode não ser viável a migração do alojamento de frangos ao invés de perus devido ao prazo retorno e há outras possibilidades rentáveis para investimento do valor que seria utilizado para viabilizar a mudança.
