Biomass and carbon storage in an age-sequence of Acacia mangium plantation forests in Southeastern region, Vietnam

Aim of the study: The major objective of this study was to estimate the biomass increment and carbon (C) storage of the main ecosystem components in an age-sequence of three Acacia mangium plantation stands.Area of study: Chang Riec Historical - Cultural Forest, Southeastern region, Vietnam.Material and methods: In order to assess the biomass of different tree components, 36 trees with diameter at breast height ranging from 13.38 to 22.87 cm were harvested from the different aged stands. Biomasses of understory (shrubs and herbs), and litter were also determined. Carbon storage in the trees and understory biomass, litter, and mineral soil (0-50 cm) were determined by analyzing the C content of each compartment.Main results: The biomass in trees, understory vegetation, litter, and ecosystem increased with stand age. Soil C represented 61.99% of the total, aboveground tree biomass C made up 26.73%, belowground tree biomass C accounted for 7.01%, and litter comprised 2.96%, whereas only a small amount (1.30%) was associated with understory vegetation. The average C content of total tree (47.97%) was higher than those of understory and litter. Soil organic C stock in the top 50 cm depth in 4-, 7- and 11-year-old stands of A. mangium were 86.86, 126.88 and 140.94 Mg. C ha-1 respectively. Soil C concentration decreased continually with increasing soil depth. Total C storage of three planted forests ranged from 131.36 to 255.86 Mg. C ha-1, of which 56.09 - 67.61% of C storage was in the soil and 26.88 - 40.40% in the trees.Research highlights: These results suggest that A. mangium is a promising afforestation tree species with fast growing, high biomass accumulation and high C sequestration potential.Keywords: Acacia mangium plantations; Biomass; Ecosystem carbon storage; Age-sequence; Vietnam.

Alternative seed treatment methods for plant pathogen control in sweet pepper crops

: The health and physiological quality of sweet pepper seeds were assessed along with the use of alternative methods by heat therapy, plant extracts, chemical and biological products to control plant pathogens associated to the seeds. The in vitro experiments assessed the effect of the treatments applied to the seeds to control the identified plant pathogens. After treatment, the seeds were plated, incubated and assessed after seven days. An in vivo experiment was also carried out with the treatments that presented the best plant pathogen control in the seeds, which were treated and sown and after 30 days the plants were sprayed with a C. gloeosporioides suspension. The severity was assessed by a score scale specific to the pathogen system. The treatments with best plant pathogen control in the seeds were aqueous basil extract 5%, heat therapy 45° C/25 minutes, Thiophanate methyl, Quality ® and B. methylotrophicus isolate, MGSS 274. In anthracnose management, the basil extract, MGSS 274 and Quality ® reduced disease severity in sweet pepper plants.
The Effects of Digital-Technology Adoption on Productivity and Factor Demand: Firm-Level Evidence from Developing Countries

This paper presents firm-level estimates of revenue-based total factor productivity premiums of manufacturing firms adopting digital technology in 82 developing economies over 2002? 19. The paper estimates productivity using the control function approach and assuming an endogenous revenue-based total factor productivity process, which is a function of multiple firm-choice variables. It estimates the effects of digital technology adoption, learning by exporting, and managerial experience on revenue-based total factor productivity and factor demand. The results reject the null hypothesis of an exogenous revenue-based total factor productivity process, in favor of one in which digital technology adoption, along with the other choice variables, affects revenue-based total factor productivity and factor demand. The estimated premiums are positive for 67.3 (email adoption), 54.6 (website adoption), 59.4 (learning by exporting), and 60.6 (managerial experience) percent of the sample. The probability-adjusted median (log) revenue-based total factor productivity premium associated with email adoption is 1.6 percent and that of website adoption is 2.2 percent, with the latter being higher than the premiums corresponding to exporting and managerial experience. On average, changes in digital technology adoption, email, and website are labor and capital augmenting. The paper also explores the role of complementarities among the firm choice variables.
‘Dorsal vessels’? 3D-reconstruction and ultrastructure of the renopericardial system of Elysia viridis (Montagu, 1804) (Gastropoda: Sacoglossa), with a discussion of function and homology

So-called ‘dorsal vessels’ are poorly described network-like structures associated with the renopericardial system and located dorsally beneath the epidermis in different groups of heterobranch gastropods. So far, homology assumptions among the different ‘dorsal vessel systems’ have been hampered by a lack of comparative histological and ultrastructural data. In the present study, we provide the first detailed 3Dreconstruction of a sacoglossan ‘dorsal vessel system’, based on histological semithin sections combined with ultrastructural data. The renopericardial system of Elysia viridis comprises a monotocardial heart, surrounded by a sac-like pericardium that is connected with a ventrally situated kidney. Our histological data show that the ‘dorsal vessels’ connect to the atrium, rather than the pericardium as previously reported. The ‘dorsal vessels’ investigated herein entirely lack an endothelium and are thus more correctly termed ‘dorsal haemolymph sinuses’. With some exceptions, there is a conspicuous correlation between the ability of Sacoglossa to retain plastids from their algal prey and the presence of dorsal haemolymph sinuses. Thus, the latter might enhance circulation and form an internal recycling system that transports oxygen from the site of photosynthesis to the organs and carbon dioxide in the opposite direction. There are considerable structural and histological differences in the ‘dorsal vessels’ of Sacoglossa, Acochlidimorpha and likely Nudibranchia, probably reflecting independent developments to cope with different environmental stress factors and thus to adapt to various ecological niches. Further comparative microanatomical and ultrastructural (re)investigation of missing lineages are required for a better understanding of the variability of the renopericardial complex in heterobranch gastropods and of modifications of the circulatory system.
Moral Stories and Young Children’s Confession of Misdeeds in Relation to Their Perception of Honesty and Its Consequences

ABSTRACT This study investigated the effect of moral stories on children’s honesty during a temptation resistance paradigm in a large sample of 3 to 6-year-olds (N = 296). Both children and their parents were also asked to anticipate if a child vignette protagonist would confess to a minor misdeed and also to predict the consequences of this potential confession. Research Findings: Moral stories emphasizing positive or negative consequences for confessions of a misdeed did not significantly alter children’s deceptive behavior. Moreover, the protagonist’s expected confession in the vignette also proved unrelated to children’s own transgression (peeking), subsequent lying behavior, or to their subsequent confession of the transgression in the temptation resistance paradigm. Parents and children concurred in anticipating that the vignette protagonist would confess. However, while most children expected aversive consequences for the protagonist confession (punishment), most parents expected non-aversive, positive ones (mainly praise and encouragement). Practice or Policy: Our results do not support the benefits of reading moral stories about fictional characters for promoting honesty. Children and parents had divergent interpretations of the consequences of confessions. Practices encouraging honest behavior should reduce punitive behaviors and reward children’s truth telling, which is not what most children consider to be the case, despite their parents’ views on the topic.
The Amount of Phosphate Solubilization Depends on the Strain, C-Source, Organic Acids and Type of Phosphate

Abstract Although production of organic acids (OAs) is usually mentioned as the main mechanism of phosphate solubilization, the relationship between carbon sources (C-sources) and OAs produced during phosphate-solubilization by microorganisms is still poorly understood. We evaluated the influence of different C-sources on FePO4·2H2O and Ca3(PO4)2 solubilization by bacteria and on the identity/quantity of the OAs produced. Our results showed that the amount of phosphate solubilization depends on the strain, C-source, OAs, and type of phosphate. Among the five strains under study isolated from cowpea nodules (Rhizobium tropici strain UFLA 03-08, Acinetobacter sp. strain UFLA 03-09, Paenibacillus kribbensis strain UFLA 03-10, P. kribbensis strain UFLA 03-106, and Paenibacillus sp. strain UFLA 03-116), three of them solubilized Ca3(PO4)2 in all C-sources. The influence of C-sources on Ca3(PO4)2-solubilization increased in the following order: cellulose < lactose < mannitol < glucose. A significant positive correlation between the amount of phosphorus solubilized from Ca3(PO4)2 and the concentration of total OAs in the presence of glucose and mannitol was observed for these three strains. In the presence of glucose, the highest solubilization rates are associated with high concentrations of tartaric acid, and in the presence of mannitol, are associated with maleic acid. Only one strain produced OAs in the medium with lactose and Ca3(PO4)2, but there was no OAs in the medium containing cellulose. Despite the production of OAs, albeit in small concentrations, in all the C-sources investigated, FePO4·2H2O-solubilization was not observed. Thus, a relationship among C-sources, OAs, and phosphate solubilization was not always verified.
Patient-Reported Outcomes and Early Complications After Synthetic Cartilage Device Implantation

Background: Previous Level I studies show promising results for the use of a hydrogel synthetic cartilage implant (SCI) for the treatment of hallux rigidus. A recent independent retrospective review has put those results into question, however. The purpose of this article is to report patient-reported outcomes and early complications using this implant so as to add to the paucity of data in the literature regarding this implant. Methods: This was a retrospective chart review of patients undergoing hydrogel synthetic cartilage implant for the treatment of hallux rigidus from July 2017 to November 2018. Data collected included patient demographics, radiographic grading, and outcomes: Veterans Rand 12 Item Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS), patient satisfaction, and complications. Fifty-four patients (59 feet) with an average age of 57.6 (range, 39-78) years were analyzed. The average latest follow-up was 18.9 (range, 3-31.3) months. Body mass index was 26.7 (range, 18.7-35.2). None were diabetic and 5 were smokers. Results: The mean outcome improvements were 6.5 points (VR-12 Physical), 17.2 points (FAAM ADL), 27.4 points (FAAM Sport), and 18.4 points (VAS) (P < .01 for each). Scores were significantly improved from preoperatively to most recent follow-up for FAAM ADL (71.0 vs 88.2 points), FAAM Sports (44.6 vs 72.0 points), and VAS (49.4 vs 31.0) (P < .01). Overall, 72.5% patients would definitely or probably have the operation again. Ten patients (18.5%) went on to have revision surgery. Of these, 7 patients were revised to an arthrodesis, and 1 metal hemiarthroplasty and 2 implants were removed because of infection. Conclusion: Synthetic cartilage implantation for the treatment of hallux rigidus demonstrated improved pain and outcome scores at short-term follow-up. Reoperation and conversion to fusion rates were comparable to prior studies. Level of Evidence: Level IV, case series.
Cytokine storm is the cryptic killer behind coronavirus disease-2019 infections, review of the current evidence to identify therapeutic options

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease 2019) is currently a rapidly disseminating viral infection that turned into a global pandemic with daily increasing mortality The exaggerated host immune response (hypercytokinemia) caused by SARS-CoV-2 was found to be the main contributor to fatality rather than the genuine effect of the viral infection The challenging situation caused by the absence of definitive antiviral therapy, as well as the implication of cytokine storm syndrome (CSS) in cases of SARS-CoV-2, necessitate screening for alternate therapeutic targets and examining the possibility of repurposing already approved drugs Treatment of CSS using immunomodulators and immunosuppressants - indicated for inflammatory diseases, autoimmune diseases and viral infections, with acceptable safety and efficacy - represents a potential therapeutic option for reducing mortality associated with SARS-CoV-2 This article aims to review the role of cytokines in CSS, present an overview of immunomodulators and immunosuppressive clinically indicated to counteract the effect of cytokines with the overarching goal of drawing attention to potential therapeutic options for further investigation, clinical trials, and pharmaceutical research
Determinants of E-invoice Adoption: Empirical Evidence from Vietnam

This paper aims to investigate the effect of the factors on the e-invoice at its infant stage of adoption in the context of Vietnam. Data were collected by using a questionnaire delivered to 318 participants who are managers and accountants of companies in Vietnam from June to September 2019. The statistical methods approaches are employed to address the research issues including Cronbach’s Alpha testing, Explanatory Factor Analysis (EFA), and Confirmation Factor Analysis (CFA). Then, Structural Equation Modeling (SEM) is employed to assess the proposed hypotheses model of e-invoice adoption in Vietnam. The research findings showed that direct factors have a statistically significant impact on the e-invoice adoption towards behavior, and perceived behavioral control. Perceived usefulness and perceived ease-ofuse positively affect attitude towards the behavior. These factors, in turn, are impacted by perceived compatibility. Based on the research results, some practicable suggestions are proposed in order to boost the number of Vietnamese enterprises voluntarily adopting e-invoice. This study indicates the important impacts of the user’s attitude and perception about control ability on intention to use. In addition, some key intuitive recommendations were proposed aiming to improve the success of the e-invoice adoption of enterprises in the context of Vietnam.
Theoretical investigation of the instability of turbulent capillary jets

While a stability theory has existed for a long time for the laminar capillary jet, there is a lack of theoretical approaches for the turbulent so far. Experimental results point out, however, that the decomposition mechanisms are similar for the laminar and turbulent case. Therefore, an attempt is made to transfer the approaches of the known stability theory, which in its base features goes back to Rayleigh, to the turbulent case. In order to study the effects of turbulence on the rotationally symmetric surface waves relevant in the laminar case, a model is set up that takes into account the coupling between the turbulent apparent stresses and the elongation of the liquid as a result of jet cross-section changes. This coupling is modeled using Batchelor and Proudman’s “Rapid Distortion Theory”; however, the derived results are independent in their qualitative statement of this particular turbulence model. The result of this consideration is that homogeneous turbulence exerts a stabilizing influence on rotationally symmetric surface waves and may even lead to a prevention of this breakup mechanism.

Gallium vacancies—common non-radiative defects in ternary GaAsP and quaternary GaNAsP nanowires

Nanowires (NWs) based on ternary GaAsP and quaternary GaNAsP alloys are considered as very promising materials for optoelectronic applications, including in multi-junction and intermediate band solar cells. The efficiency of such devices is expected to be largely controlled by grown-in defects. In this work we use the optically detected magnetic resonance (ODMR) technique combined with photoluminescence measurements to investigate the origin of point defects in Ga(N)AsP NWs grown by molecular beam epitaxy on Si substrates. We identify gallium vacancies, which act as non-radiative recombination centers, as common defects in ternary and quaternary Ga(N)AsP NWs. Furthermore, we show that the presence of N is not strictly necessary for, but promotes, the formation of gallium vacancies in these NWs.

INFLUENCE OF HEAT TREATMENT ON THE ANTIOXIDANT PROPERTIES OF GRIFOLA GARGAL HYDRO-ALCOHOLIC EXTRACTS

The effect of heat pretreatment of Gargal mushroom (Grifola gargal) on the extraction Grifola gargal) on the extraction Grifola gargal yield, the antioxidant activity and polyphenolic compounds of mushroom extracts was investigated. Raw Gargal mushroom was heated at 100 C and 121 C for 20 min and 45 min. Capacity was evaluated by four different assays, namely, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), and 1,1-diphenyl-2-picrylhydrazyl radical scavenging, reducing power and chelating ability. Heat pretreatment of Gargal mushroom increased the extraction yield (maximum 1.3-fold, heating at 121 C for 45 min), the polyphenol contents (maximum 1.3-fold, heating at 121 C for 20 min), and the flcontents (maximum 1.4-fold, heating at 121 C for 20 min) of the mushroom extract compared to the raw sample. There was no effect of thermal processing of Gargal mushroom on the antioxidant activity, which may be due to the potent free-radical scavenging activity of 90.9-93.3 mg ascorbic acid/L in the 2,2azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) assay and 84.0-90.0% in the 1,1
Variation of Fruit Size and Its Frequency Distribution in Chinese Torreya

ABSTRACT Chinese Torreya (Torreya grandis cv Merrillii) is a vital tree crop species in China’s subtropical region. The industrial plantations of this tree have been broadly established across the region. A study on the fruit size and frequency distribution is necessary to the plantation management and the design of machine processing. We measured Chinese Torreya trees and the fruit size at two sites in Zhuji County of Zhejiang Province, the central production area of Chinese Torreya. Our results indicate that the average fruit volume is about 10 cm3, with an average length of 3.0 cm and an average width of 2.0 cm. There is no significant difference in the average fruit size (volume, length, width) among different trees. The pattern of frequency distribution in fruit volume follows a unimodal distribution with the highest frequency around the average volume of 10 cm3. The pattern of the accumulated frequency distribution is in the “S” shape. Taylor’s power laws exist in the fruit volume in most trees with different scaling exponents, which are significantly correlated with the minimum fruit volume on each tree. Multiple domains are found in Taylor’s laws for the fruit lengths and widths. Our study provides necessary background information on fruit size and its frequency distribution for Chinese Torreya. The results may also stimulate further research on the complexity between environmental factors and fruit size and distribution.
“Before She Was Born, I Ate Cheerios and Beer for Dinner”: A Qualitative Examination of Green Parenting in Lowcountry South Carolina

Drawing on both social practice and social innovation research, this article analyzes 48 qualitative interviews to explore the narratives of self-described green parents who live in Lowcountry South Carolina. The interviewees talked about their motivations, challenges, and understandings of the goals and meanings of green parenting. They reported that the arrival of young children represented a new challenge but also triggered motivations to continue and often intensify green lifestyles. Parents voiced three key challenges: living “green” in a “red” state, time and financial constraints, and navigating environmental media. In parallel, they articulated three main goals: to limit their impact on earth, to live healthier lives, and to socialize their children into green living. When asked about meanings, parents stressed the overlapping importance of engaging in conscious decision-making, building connections to people and nature, and cultivating overall well-being. This study suggests that parents remain resilient in the face of multiple challenges and innovate by socializing their children to live green lifestyles.
