Published: December 2022

High-precision cavity locking is crucial for squeezing optical fields. Here, a bootstrapped low-noise photodetector is utilized in the generation process of the squeezed state of light. This process is based on a combination of a modified trans-impedance amplifier (TIA) circuit and a two-stage bootstrap amplifier circuit. This not only achieves high-precision and long-term stable locking of the optical cavity, but it also improves the degree to which the light field is squeezed. The experiment results show that the detector has a high signal-to-noise ratio (SNR) of 26.7 dB at the analysis frequency of 3 MHz when measuring the shot noise with an injection optical power of 800 µW, and the equivalent optical power noise level is lower than 2.4

Hz

in the frequency range of 1–30 MHz. Moreover, the squeezing degree of the quadrature amplitude squeezed state light field can be improved by more than 34.9% when the detector is used for optical cavity locking. The photodetector is useful in continuous variable (CV) quantum information research.

Published: December 2022

Liquid crystals are of great interest in the field of nonlinear optics due to their efficient response to low intensity light fields. Here we present a new, to the best of our knowledge, mechanism of a nonlinear optical response which is observed for a dye-doped dual-frequency nematic liquid crystal. The local increase in temperature caused by the absorption of light beam in the liquid crystal medium leads to spatial variation and inversion of the sign of the dielectric anisotropy. When an alternating current electric field with a frequency close to the cross-over frequency is applied to the liquid crystal cell, the planar orientation sustains at the beam periphery, but elastic deformation occurs in the irradiation region. In the case of a dye dopant with negative absorption dichroism, a first-order orientational transition with large bistability region is obtained.
Polarization independent electron-beam written 2-D longwave infrared guided-mode resonant filters
Authors: Gupta Neelam , Song Junyeob
Published: December 2022

We fabricated guided mode resonance filters (GMRFs) with two-dimensional (2-D) gratings operating in the 8 to 12 µm long-wave infrared (LWIR) region by depositing amorphous germanium (Ge) film to form a zero-contrast (ZC) waveguide-grating (WGG) on polished zinc selenide (ZnSe) substrates with and without antireflection coating (ARC). We employed high-spatial resolution e-beam lithography and reactive-ion etching (RIE) nanofabrication techniques. We characterized the fabricated filters for their polarization independent spectral performance using a tunable quantum cascade laser (QCL) system and a modified Fourier transform infrared (FTIR) spectrometer. Here, we will present both theoretical and experimental results and their comparison.
Input correlations impede suppression of chaos and learning in balanced firing-rate networks
Authors: Engelken Rainer , Ingrosso Alessandro , Khajeh Ramin , Goedeke Sven , Abbott L. F.
Published: December 2022

Neural circuits exhibit complex activity patterns, both spontaneously and evoked by external stimuli. Information encoding and learning in neural circuits depend on how well time-varying stimuli can control spontaneous network activity. We show that in firing-rate networks in the balanced state, external control of recurrent dynamics, i.e., the suppression of internally-generated chaotic variability, strongly depends on correlations in the input. A distinctive feature of balanced networks is that, because common external input is dynamically canceled by recurrent feedback, it is far more difficult to suppress chaos with common input into each neuron than through independent input. To study this phenomenon, we develop a non-stationary dynamic mean-field theory for driven networks. The theory explains how the activity statistics and the largest Lyapunov exponent depend on the frequency and amplitude of the input, recurrent coupling strength, and network size, for both common and independent input. We further show that uncorrelated inputs facilitate learning in balanced networks.
ToMExO: A probabilistic tree-structured model for cancer progression
Authors: Mohaghegh Neyshabouri Mohammadreza , Lagergren Jens
Published: December 2022

Identifying the interrelations among cancer driver genes and the patterns in which the driver genes get mutated is critical for understanding cancer. In this paper, we study cross-sectional data from cohorts of tumors to identify the cancer-type (or subtype) specific process in which the cancer driver genes accumulate critical mutations. We model this mutation accumulation process using a tree, where each node includes a driver gene or a set of driver genes. A mutation in each node enables its children to have a chance of mutating. This model simultaneously explains the mutual exclusivity patterns observed in mutations in specific cancer genes (by its nodes) and the temporal order of events (by its edges). We introduce a computationally efficient dynamic programming procedure for calculating the likelihood of our noisy datasets and use it to build our Markov Chain Monte Carlo (MCMC) inference algorithm, ToMExO. Together with a set of engineered MCMC moves, our fast likelihood calculations enable us to work with datasets with hundreds of genes and thousands of tumors, which cannot be dealt with using available cancer progression analysis methods. We demonstrate our method’s performance on several synthetic datasets covering various scenarios for cancer progression dynamics. Then, a comparison against two state-of-the-art methods on a moderate-size biological dataset shows the merits of our algorithm in identifying significant and valid patterns. Finally, we present our analyses of several large biological datasets, including colorectal cancer, glioblastoma, and pancreatic cancer. In all the analyses, we validate the results using a set of method-independent metrics testing the causality and significance of the relations identified by ToMExO or competing methods.

Published: December 2022

Snakebite envenomations (SBEs) in pregnant women can result in adverse maternal or neonatal effects, such as abortion, placental abruption, preterm labor, fetal malformations, and maternal, fetal or neonatal deaths. Despite the high incidence of SBEs in the Brazilian Amazon, there is no literature on the impact of SBEs on pregnancy outcomes. The objective of this study was to describe clinical epidemiology and outcomes associated with SBEs in women of childbearing age and pregnant women in the state of Amazonas, Western Brazilian Amazon, from 2007 to 2021. Information on the population was obtained from the Reporting Information System (SINAN), Mortality Information System (SIM) and Live Birth Information System (SINASC) for the period from 2007 to 2021. A total of 36,786 SBEs were reported, of which 3,297 (9%) involved women of childbearing age, and 274 (8.3%) involved pregnant women. Severity (7.9% in pregnant versus 8.7% in non-pregnant women) (P =0.87) and case-fatality (0.4% in pregnant versus 0.3% in non-pregnant women) rates were similar between groups (P =0.76). Pregnant women who suffered snakebites were at higher risk for fetal death (OR: 2.17, 95%CI: 1.74–2.67) and neonatal death (OR = 2.79, 95%CI: 2.26–3.40). This study had major limitations related to the completeness of the information on the pregnancy outcomes. Although SBE incidence in pregnant women is low in the Brazilian Amazon, SBEs increased the risk of fetal and neonatal deaths.

Plasmodium ovale curtisi and P. ovale wallikeri are both endemic in sub-Saharan Africa, the Middle East and Southeast Asia. Molecular surveillance data for drug resistance in P. ovale spp. is limited at present. We analysed polymorphisms in the podhfr, pocrt and pocytb genes of P. ovale spp. in 147 samples collected from travelers returning to China from Africa. Two podhfr mutations, S58R and S113N/T were detected in P. ovale curtisi with high/moderate frequencies of 52.17% and 17.39%, respectively. Evidence of positive selection (dN/dS = 2.41) was found for podhfr in P. ovale curtisi and decreased diversity (He) of microsatellite markers flanking the mutant alleles suggests that selective sweeps have occurred for both. Mutations E34G (1.50%) and L43V (1.50%) in pocrt of P. ovale curtisi, and E34G (3.70%), I102M (1.80%) and V111F (1.80%) of P. ovale wallikeri were found at low frequencies. Mutations R66K (6.20%), R75K (11.63%) and R95K (3.88%) of pocytb were found in both P. ovale curtisi and P. ovale wallikeri. These results suggest that the podhfr gene of P. ovale curtisi may be subject to drug selection in Africa, warranting further attention. We observed significant differences in the prevalence and distribution of podhfr mutations between the two P. ovale species, suggestive of fundamental biological differences between them.

Published: December 2022

The COVID-19 pandemic has caused a public health emergency in all sectors of society, including universities and other academic institutions. This study determined the seroprevalence of SARS-CoV-2 antibodies among administrators, faculty, staff, and students of a private tertiary academic institution in the Philippines over a 7 month period. It employed a serial cross-sectional method using qualitative and quantitative COVID-19 antibody test kits. A total of 1,318 participants were tested, showing 47.80% of the study population yielding IgG antibodies to SARS-CoV-2 virus. A general increase in seroprevalence was observed from June to December 2021, which coincided with the vaccine roll-out of the country. All brands yielded positive antibody formation, with mRNA vaccines having higher levels than other types of vaccines. A decreasing trend in IgG reactivity was found in vaccinated individuals after 1 to 6 months of completion of the 2 doses of the COVID-19 vaccine. Where possible, IgG and T-cell reactivity and/or neutralizing capacity against SAR-CoV-2 need to be monitored regardless of vaccine brand. Together with uptake of COVID-19 vaccines and boosters, other public health interventions such as wearing of masks and regular testing need to be continued for better protection. Effective communication is also needed to inform risks associated with activities across different settings. Investments in long-term measures such as air filtration and ventilation systems, and wastewater surveillance need to be made.
Coupling coordination development of energy-economy-carbon emissions in China under the background of “double carbon”
Authors: Dong Zhiyuan , Zhang Zenglian , Zhang Fengyuan
Published: December 2022

Based on the panel data of 30 provinces in China from 2010 to 2019, this paper measured the coupling coordination development of energy-economy-carbon emissions and investigated its regional differences and spatial convergence. The research methods in this paper include entropy weight technique method for order preference by similarity to an ideal solution, coupling coordination degree model, Dagum Gini coefficient and decomposition method, Moran’s I index, σ convergence model and β convergence model. The study found that the coupling coordination degree of energy-economy-carbon emissions in China has been continuously improved and has obvious regional and stage characteristics, but it is still on the verge of imminent disorder; the overall difference in the coupling coordination degree of energy-economy-carbon emissions shows a decreasing and then increasing trend, the main source of which is inter-regional differences; the coupling coordination degree of energy-economy-carbon emissions has a positive spatial correlation; except for the Southern Coastal Economic Zone and the Middle Yangtze River Economic Zone, there is no significant σ-convergence and β-convergence in the coupling coordination degree of energy-economy-carbon emissions system in other economic zones; the coupling coordination degree of energy-economy-carbon emissions changes fastest in the Middle Yangtze River Economic Zone. The innovation of this paper is to measure the coupling coordination degree of energy-economy-carbon emissions and to analyse its regional differences and spatial effects. It is of great practical significance to promote the coupling coordination development and regional balanced development of energy-economy-carbon emissions in China under the background of "dual carbon".

CREATION AND MAINTENANCE PROCESSES OF MALACOLOGICAL COLLECTIONS OF CEPHALOPOD BEAKS
Authors: Lopes Vitor Estanislau de Almeida Souza , Vaske Junior Teodoro
Published: December 2022

The cephalopods have in their mouth a pair of chitinous beaks used to cut their prey. The identification of these beaks is diagnostic for species and considered a difficult task, although very useful in the identification of species and their ecological inferences. This work aimed to create and maintain a didactic collection of cephalopod beaks. The curation process involved since the preparation of the preserving liquid and bottles to the choice and identification of the specimens. It was chosen to keep the collection stored in a humid way, in 80% vol. alcohol and 5% glycerin. A total of 562 beaks, from 50 taxa from different sources along the Brazilian coast, were identified from stomach contents of predators, scientific collections and commercial fishing. Although the available bibliography on curating biological collections, the lack of specific material on malacological collections, especially on cephalopod beaks, makes the curation process more difficult, hence the importance of organizing scientific and educational collections for these purposes.Keywords:Â Cephalopoda; beaks; curation; species identification.

Purpose: This study examined three novice Korean teacher educators’ multicultural social justice teaching experiences who work in an early childhood teacher education program in the United States. An understanding of the participants’ teacher educating practices from a phenomenological perspective is presented. Methods: Three semi-structured interviews with each participant were conducted, which were guided by Seidman’s three-interview series. Results: The research found that all three participants demonstrated a strong belief that notions of multicultural social justice should be incorporated into all classrooms. However, they shared a timid approach rather than proactively creating a space for addressing structural inequities. This was understood to be related to the participants being situated in multilayered dilemmas. Conclusion: Conceptual, pedagogical, cultural, and political dilemmas encountered by the participants were delineated and practical suggestions for supporting teacher educators in delivering multicultural social justice teaching at an institutional level are detailed.

THE CLASSICAL POLITICAL ECONOMY: CRITICISM AND CONTROVERSY AROUND THE MID-NINETEENTH CENTURY
Authors: MORSELLI Alessandro
Published: December 2022

The present work highlights the insufficiency of classical methodology to explain economic phenomena. The classical formulation left the notion of value unspecified, so there is room for the marginalist current, which abandons the classic value-work theory of the and replaces it with a theory of value based on marginal utility. The scenario changes and the attention is no longer paid to the classical social aggregates, but to individuals and economic subjects, passing from objectivity to the subjectivity of individual choices. From the marginalist principles, which still have an important influence today, the neoclassical school is constituted, which sets itself the objective of highlighting the advantages of economic liberalism, already highlighted by classical authors, but through different instruments compared to those used in the past. In this way we will have the opportunity to observe how the study of economics becomes more scientific, general and universal.
LEAD-LAG AND RELATIONSHIP BETWEEN MONEY GROWTH AND INFLATION IN TURKEY: NEW EVIDENCE FROM A WAVELET ANALYSIS
Authors: TURSOY Turgut , MAR’I Muhammad
Published: December 2022

The study investigates the relationship between money supply and inflation and Turkey by employing wavelet analysis, mainly continuous wavelet analysis, cross wavelet transforms and wavelet coherence and phase-difference, for the period from 1987 to 2019. Our main finding confirms the modern quantity theory of money about the existence of a relationship between inflation and money supply in the short-run and long-run, and also confirms the traditional quantity theory of money about the existence of a relationship in the long run. The phase difference confirms the existence of a bidirectional relationship between money supply and inflation. The result is consistent with both the traditional quantity theory of money in the long run and the modern quantity theory of money in the short-run and long-run in terms of the existence of a relationship between money supply and inflation.

INVESTIGATING THE GOVERNMENT REVENUE–EXPENDITURE NEXUS: EMPIRICAL EVIDENCE FOR THE FREE STATE PROVINCE IN A MULTIVARIATE MODEL
Authors: OMOSHORO-JONES Oyeyinka S.
Published: December 2022

This paper examines the government revenue–expenditure nexus for the Free State Province in a multivariate vector error correction model (VECM) using real GDP and inflation as control variables over the period 2004Q2–2018Q1.Cointegration and intertemporal (causal) links among variables were established employing Johansen (1995) and Toda-Yamamoto (1995) non-Granger causality tests. The results of the cointegration analysis confirm the existence of a long-run relationship between variables. The results of the causal analyses show a bidirectional causality between government revenues and expenditures in both the long-run and short-run supporting the fiscal synchronization hypothesis. Real GDP and inflation individually Granger-causes government revenue, in both the long-run and short-run, stressing their importance on generating revenue. Based on these findings, an isolated fiscal measure to raise tax-revenues or cut expenditure will exacerbate fiscal imbalance. On the policy front, the Free State government should adhere to a planned budget process, devise innovative revenue-generating strategies to circumvent the burden of producing inflation revenue, as well as utilize its autonomy on fiscal instruments to maintain a sustainable fiscal policy path, and stimulate economic growth.
ESTIMATING THE RELATIONSHIP BETWEEN GOVERNANCE, ECONOMIC GROWTH, INEQUALITY AND POVERTY
Authors: TOUITOU Mohammed
Published: December 2022

The main purpose of this paper is to estimate the relationship between governance, economic growth, inequality and poverty for 81 countries for the period 2000-2016. We divided the countries into three groups, low-income countries, lower-middle-income countries and upper-middle-income countries. To answer our research question, we use a structural model with simultaneous equations on Panel data. Our results show that the positive or negative impact of governance on the growth-inequality-poverty triangle changes depending on the dimension of governance taken into account and the sample being studied. Given the negative relationship between inequality and growth, democracy should a second time positively affect economic growth through the reduction of inequalities.
THE ECONOMIC BUBBLE AND ITS MEASUREMENT
Authors: GORGA Carmine
Published: December 2022

In mainstream economics, the sight is restricted to forms of financial bubbles. In Concordian economics, rather than the behavior of the financial markets. instead, a bubble is defined as a separation of monetary values from values of real wealth. Hence, the concern is with the behavior of the entire economic system. Once defined, Concordian economics allows us to measure the bubble. To obtain this result, Concordian economics overcomes one of the major hurdles in economics, that is the measurement of real wealth as an entity separate and distinct from monetary wealth.
ASSESSING THE IMPACT OF INTEGRATION ON ECONOMIC GROWTH AND FOOD SECURITY IN ECOWAS

Published: December 2022

This study analyzes the potential of regional integration through the culture of trade value chains in accelerating economic growth and achieving food security with a focus on ECOWAS. Some strategies that regional integration can promote to stimulate economic growth and increase food security are compared. The study examines whether countries must develop strategies to raise international trade through increasing openness degree or whether countries must develop policies to reinforce community or regional trade through the potential of value chains inside the regional integration. Three instruments are investigated (trade openness, intra-regional trade openness and the community insertion to value chains). Two models are estimated with panel fixed effects using data from 1995 to 2012. The findings support that regional integration needs to be strengthen and better promoted in order to stimulate the potential of each country to move from discontinuous growth to sustained growth. International trade is not a solution for ECOWAS countries to boost economic growth, but regional trade linked to creation of value chains among each country can be the engine of the region growth and food security.

Published: December 2022

The Spatial linkages between regions are an important part of a regional economy as an analysis of relations and interactions between regions. Regional economic studies tend to focus only on the independence of a region so that it does not consider the spatial effects that occur between one region and another. This study focuses on looking at spatial autocorrelation which will produce spatial patterns and spatial linkages between regions of the gross regional domestic product and the human development index, with the findings of seeing spatial interactions and patterns of similarities or differences in the formation of the two variables between regions. The research area focuses on 60 districts and cities in 5 provinces of Southern Sumatera with the 2015-2019 research year, the analysis method uses Geographic Information Systems with Geoda software, the results of the calculations will produce Moran’s I, LISA Significance and Clustered maps.  The outcomes show that there has been a spatial relationship as certain autocorrelation of GRDP and HDI, the formation of the economy and human capital has a spatial relationship, results of Moran'I show that the positive value of the two variables has a group pattern and has a level of formation of GRDP and HDI with the same characteristics, moran scatterplot shows the similarity with the resulting region divided into 4 quadrants. The LISA cluster map and the LISA marking are the similarities in the findings of the GRDP and HDI results, but both variables have no findings of Low-high patterns.

Los patrones de violencia se relacionaron con diferentes variables tales como experiencias adversas en la infancia, variables sociodemográficas, relación familiar e indicadores de salud mental. Estos patrones evidencian que la violencia en las relaciones de pareja durante la adolescenciason un fenómeno complejo y multifactorial.
Da rugiada a ruggine. Poesia dialettale e ambiente: Pasolini, Zanzotto, De Vita
Authors: Malicka Paulina
Published: December 2022

The scope of the present article is to reflect upon the question of the environment within the context of the discussion concerning the use of dialect in the poetry of Pier Paolo Pasolini, Andrea Zanzotto, Nino De Vita and other poets from Sicily. Commencing from the concept of ‘diversity’, as intended by Pasolini as the disappearance of the rural world, which occurs in step with the eclipses of dialectal variety, the essay will demonstrate how the environment – the crucial focus of the poetry of the above mentioned poets – converges concepts of dialects, territoriality and animality. The ecocritical method, which is applied in this study, enables one to signal the urgency to reflect upon the situation of contemporary poetry, in particular of Sicilian poetry, which has its roots in Nino De Vita’s poetic works, inextricably tied to the place, the natural and the cultural context of the island. The new Sicilian poetry does not cancel ‘diversity’, which on the contrary is capable of confronting environmental issues – at times also beyond the island’s borders – and it feeds from the lymph, from the root of the dialect.
Neural Signatures of Actively Controlled Self-Motion and the Subjective Encoding of Distance
Authors: Schmitt Constanze , Krala Milosz , Bremmer Frank
Published: December 2022

Navigating through an environment requires knowledge about one’s direction of self-motion (heading) and traveled distance. Behavioral studies showed that human participants can actively reproduce a previously observed travel distance purely based on visual information. Here, we employed electroencephalography (EEG) to investigate the underlying neural processes. We measured, in human observers, event-related potentials (ERPs) during visually simulated straight-forward self-motion across a ground plane. The participants’ task was to reproduce (active condition) double the distance of a previously seen self-displacement (passive condition) using a gamepad. We recorded the trajectories of self-motion during the active condition and played it back to the participants in a third set of trials (replay condition). We analyzed EEG activity separately for four electrode clusters: frontal (F), central (C), parietal (P), and occipital (O). When aligned to self-motion onset or offset, response modulation of the ERPs was stronger, and several ERP components had different latencies in the passive as compared with the active condition. This result is in line with the concept of predictive coding, which implies modified neural activation for self-induced versus externally induced sensory stimulation. We aligned our data also to the times when subjects passed the (objective) single distance d_obj and the (subjective) single distance d_sub. Remarkably, wavelet-based temporal-frequency analyses revealed enhanced theta-band activation for F, P, and O-clusters shortly before passing d_sub. This enhanced activation could be indicative of a navigation related representation of subjective distance. More generally, our study design allows to investigate subjective perception without interfering neural activation because of the required response action.

While the brain has evolved robust mechanisms to counter spatial disorientation, their neural underpinnings remain unknown. To explore these underpinnings, we monitored the activity of anterodorsal thalamic head direction (HD) cells in rats while they underwent unidirectional or bidirectional rotation at different speeds and under different conditions (light vs dark, freely-moving vs head-fixed). Under conditions that promoted disorientation, HD cells did not become quiescent but continued to fire, although their firing was no longer direction specific. Peak firing rates, burst frequency, and directionality all decreased linearly with rotation speed, consistent with previous experiments where rats were inverted or climbed walls/ceilings in zero gravity. However, access to visual landmarks spared the stability of preferred firing directions (PFDs), indicating that visual landmarks provide a stabilizing signal to the HD system while vestibular input likely maintains direction-specific firing. In addition, we found evidence that the HD system underestimated angular velocity at the beginning of head-fixed rotations, consistent with the finding that humans often underestimate rotations. When head-fixed rotations in the dark were terminated HD cells fired in bursts that matched the frequency of rotation. This postrotational bursting shared several striking similarities with postrotational “nystagmus” in the vestibulo-ocular system, consistent with the interpretation that the HD system receives input from a vestibular velocity storage mechanism that works to reduce spatial disorientation following rotation. Thus, the brain overcomes spatial disorientation through multisensory integration of different motor-sensory inputs.

Sübye; kavun çekirdekleri, şeker ve su ile hazırlanan geleneksel bir soğuk içecektir. Bu çalışmada ağız, mide ve bağırsaktaki sindirimi taklit eden in vitro bir model kullanılarak şeker ve tatlandırıcı ile hazırlanan sübye formülasyonlarında toplam fenolik madde ve toplam antioksidan kapasitedeki değişimlerin belirlenerek gıda matrisinin fenolik bileşiklerin biyoerişilebilirliğine olan etkisinin araştırılması amaçlanmıştır. Elde edilen sonuçlar sübye formülasyonlarında şeker ilavesinin toplam fenolik madde (%42–64) (P <0.05) ve toplam antioksidan kapasite (%13–172) biyoerişilebilirliğini arttırdığını göstermiştir. Tatlandırıcı ile hazırlanan sübye formülasyonlarında ise içeceklerin büyük kısmında fenolik bileşik (%80) ve antioksidanların (%16–62) biyoerişilebilirliği artmakla beraber bazı formülasyonlarda tatlandırıcının toplam fenolik madde ve toplam antioksidan kapasite biyoerişilebilirliği açısından önemli düzeyde bir etkisinin olmadığı görülmüştür. Sonuç olarak, bu çalışmada elde edilen bulgular şeker veya tatlandırıcı varlığının fenolik bileşiklerin biyoerişilebilirliğini genel anlamda olumlu yönde etkilediğine dikkat çekmiştir.

Lands Without Water: The Conflict Between Ejidatarios and Haciendas Over Water, Naucalpan, Mexico, 1920-1940

Since 1917, a great change in land tenure took place in this country, through the endowment and restitution demanded by the towns of Mexico. In the case of the municipality of Naucalpan, in the State of Mexico, the requests for endowments and restitution of land began in 1917. It was during the 1920s when the land began to be distributed to the peasants, but the water did not reach the ejidal lands. The large haciendas (estates) were able to conserve the use of water resources by having legal license to do so. This article exposes the struggle of the peasants of Naucalpan to obtain irrigation water from the Hondo River, the main source of water in this area. The matter was partially resolved in the 1930s thanks to the Regulation of this river, although its implementation had many complications by the fraccionistas (persons who buy sections of the estates) of the old haciendas. Throughout the 1930s, the distribution of water was carried out, after almost ten years of a tense situation between the ejidatarios (ejido members) and the large properties.

With an area of 1,575 km2, the coastal area of Phu Yen province (the area to be established in Phu Yen Geopark, hereinafter referred to as the research area) is a place with great potential for local heritage. Initial research results have established 9 types of geological heritage here including: Paleontology; Geomorphology and Landscape; Paleo-environment; Rock; Stratigraphy; Minerals; Geo-Economics; Tectonic structure, evolutionary history of geological and Quaternary geology, marine geology, and ocean-continent interactions. The most valuable geological heritages include: Fossil leaves, fossil wood, fossil diatomae, Neogene age in Tuy An; Columnar basalt in Da Dia Reef, in Hon Yen and elsewhere; beautiful lagoons, bays and beaches; Magma formations related to the Indosini orogeny and the collision between the Indochinese geo-lithic with the Vietnam-China complex; The difference in vertical movement in Neogene - Quaternary creates mountainous and hilly terrain in the northern, western and southern parts, while the eastern part is a plain, bordering the sea; Historical development of Quaternary sediments created 4 terraces along the Ba River valley; marine activities created 3 coastal erosion shelves. The study of geological heritage and other heritage values is the scientific basis for establishing a geopark in Phu Yen. Key words: geological heritage, Phu Yen

This study determined emissions of incense burning, a traditional worship activity in Asian countries, under different ventilation conditions. The experiments were conducted in a chamber with a volume of 1 m3 (1´1´1 m3) without ventilation or under mechanical ventilation (6 m3/h). There were four different types of traditional and aromatic incense in terms of length (in centimeter) and color, including 27.0 cm (traditional Inc1 - yellow), 21.5 cm (aromatic Inc2 - brown), 30.0 cm (aromatic Inc3 - dark yellow) and 19.0 cm (traditional Inc4- dark red color). The incence was placed and lighted at 0.5 m in height inside of the chamber. PM10 and PM2.5 were directly monitored in the whole process of incense burning using Air Quality Detector (GM8803 and SIBATA - LD-5R) at the same position of 0.5m in height. VOCs was measured by chromatography at three different periods, i.e., before the incense was lighted, during the process of burning, and after the incense burned out. Study results showed that the variation of PM concentrations was separated into three phases: (p1) PM concentrations quickly increased within 15 minutes after being lighted, (p2) PM concentrations were stable from 20 minutes to 35 minutes, (p3) PM concentrations decreased gradually. The maxinum concentrations of PM10 without ventilation for Inc1, Inc2, Inc3, Inc4 were 2138, 2293, 2259, 2210 µg/m3, respectively; and they decreased about 40-70% under ventilation. The maxinum PM2.5 concentrations were about 870-1210 µg/m3 under ventilation or without ventilation. VOCs ended up no Benzen emissions with all the types of experimental incense. Inc1 emitted HCHO concentrations from 4.8 ppm to 5.4 ppm, which was one of the two types containing highest concentrations of Formaldehyde. Meanwhile, Inc3 emitted the lowest VOCs concentrations among the three remaining types, and no Toluen was detected, which showed the optimum effect of clean incense in comparison with traditional one.

In nature, all seeds need external agents (biotic or abiotic) to ensure their movement. Dispersion mechanisms turn out to be an essential factor in the natural distribution of plant species and in the mobilization and exchange of genetic material within and outside populations. The objective of this research was to analyze the interaction that the native wildlife in the Tamaulipas scrub has with the fruit of one of the species of the “Chapote” plant species (Diospyros texana) and its contribution to the dispersal of seeds. The research was carried out at the Experimental Campus of the Faculty of Forest Sciences of the UANL, Mexico, located in the municipality of Linares, NL, Mexico, during the month of July and August 2019. The method used was by means of photo-trapping to monitor the fauna that interacts with the species in question. It was possible to conclude that the average distance of distribution of excreta with seeds of Diospyrus texana was three meters. Some members of the wild fauna of mammals present in the vegetation of the Tamulipec scrub were white-tailed rabbit (Sylvilagus floridanus), gray squirrel (Sciurus aureogaster), raccoon (Procyon lotor), armadillo (Dasypus novemcinctus) and coyote (Canis latrans); they feed on the fruits of Diospyrus texana and thus act as dispersers of its seeds.
