Manipulation of Jasmonate Signaling by Plant Viruses and Their Insect Vectors
Authors: Wu Xiujuan , Ye Jian
Published: January 2020

Plant viruses pose serious threats to stable crop yield. The majority of them are transmitted by insects, which cause secondary damage to the plant host from the herbivore-vector’s infestation. What is worse, a successful plant virus evolves multiple strategies to manipulate host defenses to promote the population of the insect vector and thereby furthers the disease pandemic. Jasmonate (JA) and its derivatives (JAs) are lipid-based phytohormones with similar structures to animal prostaglandins, conferring plant defenses against various biotic and abiotic challenges, especially pathogens and herbivores. For survival, plant viruses and herbivores have evolved strategies to convergently target JA signaling. Here, we review the roles of JA signaling in the tripartite interactions among plant, virus, and insect vectors, with a focus on the molecular and biochemical mechanisms that drive vector-borne plant viral diseases. This knowledge is essential for the further design and development of effective strategies to protect viral damages, thereby increasing crop yield and food security.

In light of the implementation of human papillomavirus (HPV) prevention strategies, epidemiological studies in different geographical areas are required in order to assess the impact of HPV-related diseases. The purpose of the present study was to describe the burden of HPV-related hospitalizations in Sicily. A retrospective observational study estimated 43,531 hospitalizations attributable to HPV from 2007 to 2017. During the observed period, there was a decrease for all HPV-related conditions with a higher reduction, among neoplasms, for cervical cancer (annual percent change (APC) = −9.9%, p < 0.001). The median age for cervical cancer was 45 years old, with an increasing value from 43 to 47 years (p < 0.001). The age classes with greater decreases in hospital admissions for invasive cancers were women aged 35 years or more (APC range from −5.5 to −9.86) and 25–34 years old (APC = −11.87, p < 0.001) for women with cervical carcinoma in situ. After ten years for vaccine introduction and sixteen years for cervical cancer screening availability, a relatively large decrease in hospital admissions for cervical cancer and other HPV-related diseases in Sicily was observed. Some clinical characteristics of hospitalization, such as increasing age, are suggestive clues for the impact of preventive strategies, but further research is needed to confirm this relationship.

Published: January 2020

Notwithstanding the widespread use of natural and pre-exchanged zeolites for zootechnical effluent treatment, little attention has been dedicated to the variation in the chemical composition of the treated slurries, besides the effects on their NH4+ content. This paper aimed at elucidating the compositional variations in terms of major and trace elements of a raw pig-slurry (PS) after three sequential treatment cycles (TC) with three different grain sizes of natural and Na-exchanged zeolite-rich volcanic tuffs (natural ZTs and NaZTs). A series of laboratory batch experiments revealed that all ZTs had profoundly influenced the final PS chemical composition. As expected, the NaZTs were more efficient in terms of NH4+ removal than the natural ZTs, reaching almost 60% reduction of the initial content after three TCs. A parallel effect of this efficient removal was the remarkable increase in Na+. The Na-forms of ZTs led also to stronger competition with K+ ions, resulting in adsorption of this macronutrient and hence in a reduction of the fertilization value of the PS. In terms of heavy metals and other trace elements, all the treatments with ZTs had significantly increased the Li, Ba, Rb, Sr, Ga, and U content in the PS.
Legal status of surface waters—comparative study on the example of lakes
Authors: Pietkiewicz Michał , Klimach Anna , Ogryzek Marek
Published: January 2020

Water laws in post-Soviet countries have developed in vastly different ways since each state became entitled to choose its own method of regulating inland water ownership. This article analyzes the Russian Federation and selected post-Soviet states’ legal systems related to ownership of surface waters, and assesses the possibility of legal transactions of lakes and other land areas covered by surface water. The research initially centers on establishing whether lakes are owned by the state or by the county, if a lake can be subject to sale to a private person or enterprise and finally examines the different approaches of post-Soviet countries to their surface water use. In achieving these objectives, the article analyzes water law in the Russian Federation, Belarus, Ukraine and Kazakhstan. It then identifies how water ownership is regulated in these countries and compares this with United Nations assumptions of surface water ownership as a Sustainable Development Goal. Finally, the results establish that countries from the same “block” regulate water ownership similarly, and that combined regulations could enhance future implementation of international standards.

Authors: Klaiber Laura B. , Kramer Stephen R. , Young Eric O.
Published: January 2020

Quantifying the influence of tile drainage on phosphorus (P) transport risk is important where eutrophication is a concern. The objective of this study was to compare P exports from tile-drained (TD) and undrained (UD) edge-of-field plots in northern New York. Four plots (46 by 23 m) were established with tile drainage and surface runoff collection during 2012–2013. Grass sod was terminated in fall 2013 and corn (Zea mays L.) for silage was grown in 2014 and 2015. Runoff, total phosphorus (TP), soluble reactive phosphorus (SRP), and total suspended solids (TSS) exports were measured from April 2014 through June 2015. Mean total runoff was 396% greater for TD, however, surface runoff for TD was reduced by 84% compared to UD. There was no difference in mean cumulative TP export, while SRP and TSS exports were 55% and 158% greater for UD, respectively. A three day rain/snowmelt event resulted in 61% and 84% of cumulative SRP exports for TD and UD, respectively, with over 100% greater TP, SRP and TSS exports for UD. Results indicate that tile drainage substantially reduced surface runoff, TSS and SRP exports while having no impact on TP exports, suggesting tile drains may not increase the overall P export risk.
A Bi-Objective Approach for Optimizing the Installation of PATs in Systems of Transmission Mains
Authors: Creaco Enrico , Galuppini Giacomo , Campisano Alberto , Ciaponi Carlo , Pezzinga Giuseppe
Published: January 2020

This paper proposes the bi-objective optimization for the installation of pumps operating as turbines (PATs) in systems of transmission mains, which typically operate at steady flow conditions to cater to tanks in the service of water distribution networks. The methodology aims to find optimal solutions in the trade-off between installation costs and generated hydropower, which are to be minimized and maximized, respectively. While the bi-objective optimization is carried out by means of a genetic algorithm, an inner optimization sub-algorithm provides for the regulation of PAT settings. The applications concerned a real Italian case study, made up of nine systems of transmission mains. The methodology proved able to thoroughly explore the trade-off between the two objective functions, offering solutions able to recover hydropower up to 83 KW. In each system considered, the optimal solutions obtained were postprocessed in terms of long-life net profit. Due to the large geodesic elevation variations available in the case study, this analysis showed that, in all systems, the optimal solution with the highest value of generated hydropower was the most profitable under usual economic scenarios, with payback periods always lower than 3 years.

Published: January 2020

A good understanding of the frequency and magnitude of lahars is essential for the assessment of torrential hazards in volcanic terrains. In many instances, however, data on past events is scarce or incomplete, such that the evaluation of possible future risks and/or the planning of adequate countermeasures can only be done with rather limited certainty. In this paper, we present a multiidisciplinary approach based on botanical field evidence and the numerical modelling of a post-eruptive lahar that occurred in 2012 on the northern slope of the Pico de Orizaba volcano, Mexico, with the aim of reconstructing the magnitude of the event. To this end, we used the debris-flow module of the rapid mass movement simulation tool RAMMS on a highly resolved digital terrain model obtained with an unmanned aerial vehicle. The modelling was calibrated with scars found in 19 Pinus hartwegii trees that served as paleo stage indicators (PSI) of lahar magnitude in a sector of Jamapa Gorge. Using this combined assessment and calibration of RAMMS, we obtain a peak discharge of 78 m3 s−1 for the 2012 lahar event which was likely triggered by torrential rainfall during hurricane “Ernesto”. Results also show that the deviation between the modelled lahar stage (depth) and the height of PSI in trees was up to ±0.43 m. We conclude that the combination of PSI and models can be successfully used on (subtropical) volcanoes to assess the frequency, and even more so to calibrate the magnitude of lahars. The added value of the approach is particularly obvious in catchments with very scarce or no hydrological data at all and could thus also be employed for the dating and modelling of older lahars. As such, the approach and the results obtained can be used directly to support disaster risk reduction strategies at Pico de Orizaba volcano, but also in other volcanic regions.
Evaluation of Marsh Terraces for Wetland Restoration: A Remote Sensing Approach
Authors: Osorio Raúl J. , Linhoss Anna , Dash Padmanava
Published: January 2020

Marsh terracing is a wetland restoration technique that is being implemented in the northern Gulf of Mexico. Marsh terraces are segmented berms of soil built within shallow coastal ponds, designed to increase marsh area and reduce wave energy. Approximately 980 linear km of marsh terraces have been constructed over almost 30 years in Louisiana and Texas to combat subsidence and sea-level rise; however little research has been conducted to determine their effectiveness. The objective of this study was to assess marsh terrace performance. The change in marsh terrace areas was measured over time through remote sensing. This analysis was conducted using one-meter resolution imagery from the National Agriculture Imagery program (NAIP) from 2003 until 2017 from five Louisiana coastal parishes. Twenty terrace fields of study between 10 and 14 years old were randomly selected within each parish. Results show more predominant deposition (55%) than erosion (45%) in marsh terraces. Terrace fields with high channel density and thereby an external sediment supply show more deposition compared to low channel density fields. This is the first study assessing multiple marsh terrace fields performance. Results are promising, especially considering the current rate of sea level rise and subsidence in Louisiana.
The Impact of Land-Use on the Hierarchical Pore Size Distribution and Water Retention Properties in Loamy Soils

Published: January 2020

Soil hydraulic properties are very sensitive to land-use in regions susceptible to physical degradation. Intensive agricultural practices often lead to soil compaction and erosion in the investigated area. The main goal of this paper was to evaluate the impact of land-use on the pore size distribution and water retention in loamy soils. The soil water retention curve (SWRC) combined the total porosity and the water retention of the undisturbed sample at 3, 10, 31, 100, 310, and 1000 hPa suctions and the disturbed sample at 1.5 MPa. The triple-exponential model approximated the curve’s course, and its derivative defined the distinct macro-, structural, and textural pore maxima, with characteristic suctions corresponding to SWRC inflection points. The soil organic carbon content had the greatest influence on the content of all three pore classes. The water retention properties followed the hierarchical pore size distribution in the four research plots and decreased in the identical orchard > forest > grassland > arable soil order. These results show that the orchard and forest areas are the most appropriate land uses with respect to porosity and water retention, while the grassland has not fully recovered after its conversion from arable soil and remains relatively poor, and the arable soil properties are the worst.
Groundwater-Surface Water Interactions in “La Charca de Suárez” Wetlands, Spain

Published: January 2020

La Charca de Suárez (LCS) is a Protected Nature Reserve encompassing 4 lagoons located 300 m from the Mediterranean coast in southern Spain. LCS is a highly anthropized area, and its conservation is closely linked to the human use of water resources in its surroundings and within the reserve. Different methodologies were applied to determine the hydrodynamics of the lagoons and their connection to the Motril-Salobreña aquifer. Fieldwork was carried out to estimate the water balance of the lagoon complex, the groundwater flow directions, the lagoons-aquifer exchange flow and the hydrochemical characteristics of the water. The study focussed on the changes that take place during dry-wet periods that were detected in a 7-month period when measurements were collected. The lagoons were connected to the aquifer with a flow-through functioning under normal conditions. However, the predominant inlet to the system was the anthropic supply of surface water which fed one of the lagoons and produced changes in its flow pattern. Sea wave storms also altered the hydrodynamic of the lagoon complex and manifested a future threat to the conservation status of the wetland according to predicted climate change scenarios. This research presents the first study on this wetland and reveals the complex hydrological functioning of the system with high spatially and temporally variability controlled by climate conditions and human activity, setting a corner stone for future studies.
Does Salinity Affect the Distribution of the Artificial Radionuclides 90Sr and 137Cs in Water of the Saline Lakes? A Case of the Crimean Peninsula

Published: January 2020

In the framework of radioecological monitoring, the features of the distribution of the post-Chernobyl nuclear power plant (NPP) accident artificial radionuclides of 137Cs and 90Sr in the Crimean saline lakes were studied. Samples were collected from 12 Crimean lakes with a salinity range from 2 to 400 g/L in 2014–2017. Concentration of 90Sr varied from 5.9 to 313.6 Bq/m3, and 137Cs from 0.8 to 106.7 Bq/m3. Closing of the North Crimean Canal resulted in a decrease in radionuclide concentration in the lakes. About 61% of the total variability of 90Sr and 33% of 137Cs in lake water can be explained by salinity changes. The salinity affects the behavior of radionuclides in water, mainly influencing their solubility, on isotope exchange between the solution and bottom sediments, and also, probably, through its influence on accumulation of isotopes by aquatic organisms. Salinity is not the alone factor determining the behavior of radionuclides in the lakes, it only acts by interacting with other factors.
Does it Matter: Constitutionalisation, Democratic Governance, and the Human Right to Water
Authors: Schiel Rebecca , Langford Malcolm , Wilson Bruce M.
Published: January 2020

States are urged frequently by the UN, policymakers, and activists to recognise the human right to water domestically. However, does such legal incorporation, often in national constitutions, affect water policy and the realisation of the right? While several qualitative studies report positive impacts, initial quantitative assessments have questioned the systematic positive impact of the national recognition of the human right to water. Yet, such quantitative analyses of the effects of constitutional rights to water often overlook important mediating policy factors. We test specifically whether strong democratic governance is a significant condition for ensuring that the constitutional recognition of the human right to water has concrete outcomes. Results of a multivariate regression analysis on a global sample of 123 states over a 15-year period provide two findings. First, the constitutionalisation of the right to water and other economic, social, and cultural rights (ESCRs), in national constitutions alone is not associated with material benefits related to the human right to water. Second, the constitutionalisation of those rights can have positive material benefits for water access when the rights are foregrounded in democratic governance.
A Study of Precipitation Patterns through Stochastic Ordering
Authors: Ni Nan , Zhang Hao
Published: January 2020

The study of spatial and temporal changes in precipitation patterns is important to agriculture and natural ecosystems. These changes can be described by some climate change indices. Because these indices often have skewed probability distributions, some common statistical procedures become either inappropriate or less powerful when they are applied to the indices. A nonparametric approach based on stochastic ordering is proposed, which does not make any assumption on the shape of the distribution. This approach is applied to the average length of the period between two adjacent precipitation days, which is called the average number of consecutive dry days (ACDD). This approach is shown to be able to reveal some patterns in precipitation that other approaches do not. Using daily precipitations at 756 stations in China from 1960 to 2015, this work compares the ACDDs in three periods, 1960–1965, 1985–1990, and 2010–2015 for each province in China. The results show that ACDD increases stochastically from the period 1960–1965 to either the period 1985–1990 or the period 2010–2015, or from the period 1985–1990 to the period 2010–2015 in all but three provinces in China.

Se analiza la actividad editorial de la Universidad Nacional Autónoma de México (UNAM) desde una perspectiva organizacional para conocer su desempeño como sistema editorial de una Institución de Educación Superior (IES) dependiente de financiamiento público. Como metodología se utiliza el nuevo institucionalismo sociológico como método de diagnóstico organizacional porque éste concibe a las IES como organizaciones suaves en que los criterios e indicadores formales de desempeño económico no se aplican de manera directa ni se manifiestan explícitamente en la estructura y prácticas de la organización, privilegiando el alto contenido simbólico de las medidas de eficiencia y racionalidad formal. La aplicación de este método –durante el primer semestre de 2013 y mayo de 2014- en instancias editoriales, representativas de los cuatro subsistemas en que se organizan las tareas editoriales de la UNAM, muestran al quehacer editorial institucional como susceptible de incurrir en prácticas isomórficas o de homogeneización de tipo burocrático perceptibles a través de la alta descentralización de la actividad editorial; falta de coordinación entre la Dirección General de Publicaciones y Fomento Editorial y el resto de las instancias editoriales universitarias; escasa colaboración de la UNAM con redes de editoriales universitarias nacionales y extranjeras, etc.
Growth and Yield Response of Wheat to Tillage, Rice Residue and Weed Management under Rice–Wheat Cropping System
Authors: Pandey Bisheshwor Prasad , Kandel Tanka Prasad
Published: January 2020

Recent decades have seen many changes in agricultural production systems in Nepal, such as increased mechanization for harvesting of major cereal crops, which leaves a large volume of crop residue in the field, increased herbicide application for weed control, and increased adoption of reduced tillage systems. In this study, we compared the effects of tillage, rice residue and weed managements on yield and yield attributes of wheat cultivated under rice-wheat rotation in the Southern Plain (Terai) region of Nepal. The study was conducted during the wheat growing seasons (November through April) of 2013–2014, 2014–2015 and 2015–2016 in Rupandehi district. The experiment was deployed in a split-split plot design with tillage system as main plot [conventional tillage (CT) and zero tillage (ZT)], residue removal management as a sub-plot [whole residue retained (WR), partial residue retained (PR) and no residue retained (NR)], and weed management as a sub-sub plot [(manual weeding (MW) and chemical weeding (CW)], replicated three times. Analysis of variance was applied to the yield and yield attributes of wheat for fixed and interaction effects. Averaged across the years, the CT system (2.4 t ha–1) had significantly higher yield than ZT (2.2 t ha–1) but the difference was not consistent in all study years. While rice residue retention did not influence grain yield in Year1, WR produced greatest and NR produced lowest yield in Year2 and Year3, indicating potential yield increase in wheat following the whole rice residue retention in the long run. Grain yield did not significantly vary with weed management method, suggesting that manual weed control can be as effective as herbicide in weed management in wheat agroecosystem in the Southern Plains (Terai) region of Nepal.

Published: January 2020

The perception of Periodontology learning environment was measured before and after curricular restructuring by the Dundee Ready Education Environment Measure (DREEM). Undergraduate students (2nd, 3rd, 4th years; n = 266) were divided into two main groups: former curriculum (n = 131) and current one (n = 131). Total DREEM score, its five dimensions, Periodontology grades and their weighted average were compared. Student’s t test and ANOVA were used for analysis (p < 0.05). There was a statistically significant difference between the second (teachers) and fifth (social relations) dimensions and between Periodontology grades and the weighted average in both curricula. For each year, higher scores in the second dimension, Periodontology grades and the weighted average were obtained for current curriculum. Both curricula presented a significant correlation between Periodontology grades and their weighted average. Total DREEM scores for 2nd, 3rd and 4th years of current curriculum presented no differences (p > 0.05). The implementation of a new curriculum had an important impact on the students’ positive perceptions, which reflected in their academic performance

Ikan merupakan sumber protein hewani yang memiliki daya cerna yang lebih baik dan jumlah kandungan asam amino essensial yang lebih banyak dibandingkan dengan sumber protein hewani lainnya. Ikan sunglir adalah jenis ikan pelagis yang banyak hidup diperairan Nusa Utara. Ekstraksi KPI umumnya dilakukan dengan menggunakan pelarut etanol. Penelitian ini bertujuan mengkarakterisasi sifat fisiko-kimia konsentrat protein ikan yang diekstrak dari ikan sunglir. Penggunaan etanol 90% dalam mengekstraksi konsentrat protein dari ikan sunglir menghasilkan rendemen berkisar 18-20%. Hasil Penelitian menunjukkan bahwa konsentrat protein ikan sunglir memiliki kandungan protein yang tinggi dan memiliki kadar lemak yang rendah. Konsentrat protein dengan kadar protein >65% dan kadar lemak <3% tergolong sebagai konsentrat protein Tipe B sesuai dengan standar Mutu FAO 1976 tentang KPI. Hasil pengujian fisik menunjukkan bahwa KPI memiliki kemampuan penyerapan air, lemak dan densitas kamba yang cukup baik untuk diaplikasikan ke dalam bahan panganFish serve as an important source of animal protein with better digestibility and higher content of essential amino acids than other sources of animal protein. Elagatis bipinnulatus or sunglir in Indonesian is a common pelagic fish caught in Sangihe Islands. FPC is commonly extracted with etanol. Therefore, this research aims to characterise the physicochemical properties of the FPC extracted from rainbow runner. The use of 90% ethanol for exraction of FPC from rainbow runner resulted in 18-20% yield. The result shows that the local rainbow runner contained FPC with high level of protein (77.34%) but low level of fat (1.22%), classified as type B on the basis of FAO’s standard on FPC Protein, which stipulated FPC with >65% protein and <3% fat content as Type B. In addition, physical analysis proved that FPC has appropriate water and fat absorption abilities as well as kamba density, suitble for food substitute or fortification

Penelitian ini dilakukan untuk mengetahui efek gliserol + NaCl pada dendeng babi yang disimpan pada suhu kamar. Plot split dalam desain waktu digunakan dalam penelitian ini; Faktor A adalah konsentrasi Gliserol + NaCl (dibagi dalam 3 level kombinasi) sebagai berikut A₁ = Gliserol 15% + NaCl 5%, A₂ = Gliserol 10% + NaCl 10%, A₃ = Gliserol 5% + NaCl 15% dan faktor B adalah durasi penyimpanan pada suhu kamar (dibagi dalam 3 lama waktu yang berbeda) sebagai berikut B₁ = 10 hari, B₂ = 20 hari, B₃ = 30 hari; dengan tiga replikasi. Variabel yang diamati adalah kadar air, pH dan jumlah mikroba. Hasil penelitian menunjukkan bahwa penggunaan Glycerol-NaCl memberikan efek yang sangat berbeda (P <0,01) pada kadar air dan jumlah mikroba pada dendeng babi, tetapi tidak pada pH dendeng babi. Ditemukan juga bahwa durasi penyimpanan pada suhu kamar memberikan efek yang sangat berbeda (P <0,01) pada semua variabel dendeng babi. Singkatnya, penggunaan Gliserol 5% + NaCl 15% dapat memperpanjang umur simpan dendeng babi hingga 30 hariThe study was done in order to know the effect of glycerol+NaCl on jerky pork kept at room temperature. A split plot in time design was used in this study; A Factor was Glycerol+NaCl concentration(divided in 3 combination levels) as follows A₁= Glycerol 15% + NaCl 5%, A₂= Glycerol 10% + NaCl 10%, A₃= Glycerol 5% + NaCl 15% and B factor was duration of storage at room temperature (divided in 3 different length of time) as follows B₁= 10 days, B₂= 20 days, B₃= 30 days; with three replications. The variables observed were water content, pH and the number of microbes. The results showed that the use of Glycerol-NaCl gave significantly a very different effect (P <0.01) on water content and microbial amounts of jerky pork, but not on the pH of jerky pork. It was found also that the duration of storage at room temperature gave significantly a very different effect (P <0.01) on all variables of jerky pork.  In short, the use of Glycerol 5% +NaCl 15% could extend the shelf life of jerky pork until 30 days
