Authors: He Zhihui , Li Xiaofeng
Published: September 2020

During the COVID-19 epidemic period, it is essential to strengthen physical exercise and improve the health of the whole people. In this paper, based on genetic algorithm, a fuzzy control system is proposed to dynamically adjust the exercise ability of the bodybuilders under the comprehensive consideration of parameters. Through experiments and data processing, the system obtains bioelectric information related to heart rate, heart rate variability and muscle fatigue of the fitness people in the three states of not fatigue, moderate fatigue and extreme fatigue, establishes fuzzy membership function, and thus establishes personalized fitness information feedback control strategy to maintain moderate fitness intensity. By narrowing the gap between the predicted RPE value based on objective information and the measured RPE, the method provides a unified subjective and objective exercise intensity for the bodybuilders, effectively expands the time of aerobic exercise, and enhances the effect of aerobic exercise. In addition, in order to expand the scope of application of the exercise intensity control model, the service-oriented transformation is carried out to enable it to provide fitness content combinations of interest to fitness practitioners and instructors.

In rural construction, affected by covid-19, it leads to the collection and demand survey of basic information data of relevant interest groups. The specific situation of the transformation of ancient villages is also gradually increasing. However, due to the complexity of rural space, the dispersion of settlement space and the diversity of information demand of rural planning work, the data coverage is large, information acquisition is difficult, the use effect of data collection is not ideal, and there is no planning feedback mechanism. However, during the epidemic period, the staff could not carry out a series of reconstruction of ancient villages. At present, the data of village planning and construction and architectural design are complex, the needs of relevant interest groups are diversified, and regional planning is difficult. In this paper, the big data function is applied to the reconstruction of ancient villages in the epidemic period of covid-19.
Prediction and comparison of the impact of COVID-19 epidemic on the financial industry of major countries based on neural intelligent algorithm
Authors: Wang Bin , Zhou Qingyuan
Published: September 2020

The global economy appears the trend of anti-globalization under the influence of COVID-19. Based on the input-output table of lead database from 2006 to 2020, this paper divides the factors that affect the development of financial industry in China, the United States and Russia into six aspects: price, intermediate input, household consumption, government consumption, export and import. ADGA-BP neural network model is proposed in this paper, which is based on six aspects of price, intermediate input, consumer, government consumption, export and import. The intermediate input is decomposed from the perspective of industrial structure to study the interrelationship between financial industry and other industries in the three countries. The results show that the intermediate input is the main factor in the development of financial industry in the three countries, but the source industries of the intermediate input are not the same; the two factors of household consumption and price are closely related to the development of financial industry in the three countries, and they all play a role in promoting China, while the relationship between household consumption and the United States and between price and Russia is reverse; Government consumption only has a significant impact on Russia; from the perspective of mutual influence, the mutual investment between the financial industry of China and the United States is relatively large, while the relationship between the Russian financial industry and the two countries is relatively weak. It shows that under the background of covid-19, the development of financial industry is affected.

Authors: Araújo Júnior José M. , Linhares Leandro L.S. , Araújo Fábio M.U. , Almeida Otacílio M.
Published: September 2020

Newborns with health complications have great difficulty in regulating the body temperature due to distinct factors, which include the high metabolism rate and low weight. In this context, neonatal incubators help maintaining good health conditions because they provide a thermally-neutral environment, which is adequate to ensure the least energy expenditure by the newborn. In the last decades, artificial neural networks (ANNs) have been established as one of the main tools for the identification of nonlinear systems. Among the various approaches used in the identification process, the fuzzy wavelet neural network (FWNN) can be regarded as a prominent technique, consisting of the combination of wavelet neural network (WNN) and adaptive network-based fuzzy inference system (ANFIS). This work proposes the use of FWNN to infer the temperature and humidity values inside the incubator in order to certify the equipment operation. Results obtained with the analyzed neural system have shown the generalization and inference capacities of FWNNs, thus allowing their application to practical tasks aiming to increase the efficiency of incubators.
A hybrid intelligent algorithm for a fuzzy multi-objective job shop scheduling problem with reentrant workflows and parallel machines
Authors: Basiri Mohammad-Ali , Alinezhad Esmaeil , Tavakkoli-Moghaddam Reza , Shahsavari-Poure Nasser
Published: September 2020

This paper presents a multi-objective mathematical model for a flexible job shop scheduling problem (FJSSP) with fuzzy processing times, which is solved by a hybrid intelligent algorithm (HIA). This problem contains a combination of a classical job shop problem with parallel machines (JSPM) to provide flexibility in the production route. Despite the previous studies, the number of parallel machines is not pre-specified in this paper. This constraint with other ones (e.g., sequence-dependent setup times, reentrant workflows, and fuzzy variables) makes the given problem more complex. To solve such a multi-objective JSPM, Pareto-based optimization algorithms based on multi-objective meta-heuristics and multi-criteria decision making (MCDM) methods are utilized. Then, different comparison metrics (e.g., quality, mean ideal distance, and rate of achievement simultaneously) are used. Also, this paper includes two major phases to provide a new model of the FJSSP and introduce a new proposed HIA for solving the presented model, respectively. This algorithm is a hybrid genetic algorithm with the SAW/TOPSIS method, namely HGASAW/HGATOPSIS. The comparative results indicate that HGASAW and HGATOPSIS outperform the non-dominated sorting genetic algorithm (NSGA-II) to tackle the fuzzy multi-objective JSPM.
Riflessioni sul principio di trasparenza:
Authors: Allegretti Giovanni
Published: September 2020

L’articolo parte dalla decisione del governo Brasiliano di silenziare parte della produzione di dati sui danni causati dalla pandemia COVID-19, per proporre una riflessione sulla trasformazione del principio di trasparenza e della sua relazione con le politiche pubbliche. Nel ripercorrerne la complessa natura di mito e di spazio produttore di miti, attraverso la disamina di alcuni testi costituzionali e di pratiche partecipative formalizzate, il testo s’interroga su come strutturare piú solidamente le relazioni tra due ambiti importanti dell’azione pubblica: la promozione della trasparenza e quella della partecipazione civica all’azione di governo. I due campi appaiono avere molte convergenze strutturali, persino nello svuotamento graduale di significati proposto dalla retorica politica, e il loro crescente dialogo in molti paesi evidenzia la mutua capacitá di apprendimento e fertilizzazione, se pensati da subito nella loro interazione reciproca. L’analisi di come ha teso a strutturarsi negli ultimi anni il rapporto tra trasparenza e innovazioni democratiche mostra che queste ultime sono necessarie ma non sufficienti a garantire un’elevato livello di trasparenza, che richiede di affrontare problemi strutturali che riguardano l’organizzazione politico-amministrativa, le risorse, la mentalitá diffusa e la comunicazione pubblica in un determinato contesto. Per lo meno, non sono sufficienti, quando il contesto non si pone obiettivi sfidanti di ripensamento radicale della partecipazione, attraverso movimenti “a rete” che possano – incrociando sperimentazioni diverse – riflettere in forma collettiva su nuovi modi di mettere in dialogo azioni partecipative promosse “dall’alto” e “dal basso”.

Published: September 2020

In the near future, small modular reactors (SMR) potentially will play a significant role in global sustainable energy development through the growing interest in SMR implementation in both countries with developed nuclear industry (for example, in Ukraine) and countries that only start launching their nuclear energy programs. At present, there are about 50 SMR designs developed using different reactor technologies in various stages of readiness. The novelty and uniqueness of some fundamental decisions that are the basis for the specified designs and the lack of resulting of real testing of such decisions have created challenges related to ensuring nuclear and radiation safety during installation and further operation of SMR.

The paper provides general information on the activities of the SMR Regulators’ Forum (Forum) created by the International Atomic Energy Agency (IAEA) and countries that actively consider and address the use of SMR in the national energy sector to ensure efficient cooperation in dealing with the specified challenges. The paper presents the results obtained by Forum working groups, the main purpose of which is to develop common positions on issues that have already arisen or are likely to arise during the expected licensing of SMR designs in a number of countries, in particular: demonstration of comprehensive implementation of defense in depth strategy in design safety justification; use of the graded approach within the licensing process; approaches to defining zones and distances in emergency planning around NPPs with SMR. In addition, the working groups defined the best practice and approach to considering the specified issues in licensing SMR designs.

Based on the performed review, the paper provides proposals for using the available Forum results during planning and licensing of SMR designs in Ukraine and states on the need for a detailed study of its further activities.

Authors: Denisova Mariya , Bocharnikov Viktor
Published: September 2020

Wastewater is a variety of waters, as well as precipitation discharged into water bodies from industrial enterprises, domestic, livestock production, as well as settlements through the drainage system, the properties of which were deteriorated as a result of human activity. In areas where livestock complexes are located, the situation is tense. It is necessary to solve the problem of processing toxic, toxic and harmful industrial, domestic, animal waste. It is necessary to develop special sites for the destruction and recycling of these wastes. There are many ways to treat wastewater, such as screening, initial sedimentation without reagents, filtration, sorption on activated carbon, ultrafiltration, ozonation, etc. Currently, it is becoming increasingly important to use the ferrite method for wastewater treatment from heavy metal ions.

Basically, this method is widely used in wastewater treatment of galvanic production, engineering plants which in the process of their work have galvanic waste, i.e. galvanic sludge. The article presents the results of cascade filtration through various natural sorbents such as activated carbon of the BAU-A brand, gravel sand and zeolite of various fractions. The limiting indicator of the harmfulness of the studied pollutants before and after ferritization is calculated. Based on the research results, regression models were obtained that characterize the dependence of the concentration of impurities on the reaction time of ferrite reagents with poultry runoff.
Influence of agromeliorative measures on the density and water yield of sodpodzolic soil when irrigated with livestock runoff
Authors: Kopytovskiy Viktor
Published: September 2020

The article discusses the results of long-term field research on irrigation of perennial grasses with livestock runoff. The aim of the research was the experimental justification of land reclamation measures and drainage-free run off during irrigation of land with runoff from pig-breeding complexes. Experimental studies were conducted on a specialized reclamation system in Orsha district of Vitebsk region, where the soil cover is represented by sod-podzolic loamy soils. The experimental design included 8 options. As a result of research, it was found out that irrigation with livestock runoff leads to compaction of the upper soil layers.

In the arable layer of 0–20 cm, the additional density increased from 1.26 to 1, 32 g/cm3, or 4.8 %, compared to the control, and in variants with irrigation and drainage measures, the compaction was somewhat less. In the soil layer of 0–40 cm, deconsolidation was greater only in the variants with soil deepening and loosening by 4 %, and when applying straw – by 5.1 %.In the 0–60 cm layer, a decrease in the density of addition was observed only in the variants with deep loosening and the introduction of straw. It was also found out that soil water loss varies over time. It is most intense in the first 2–3 hours and almost completely stops after 10–18 hours for

monoliths with a thickness of 0.4–0.6 m, and in monoliths of 1.0 m, after 36–48 hours. The highest intensity of water loss was registered in options 5, 6 and 7. The lowest was in the control variant and option 2, where no land reclamation measures were taken. In options 5, 6 and 7, a decrease in the intensity of water loss by years was noted.

Thus, in option 5 in 2000, water loss amounted to 0.9 mm /h, in 2001 – 0.87 mm/h, and in 2002 – 0.85 mm/h. Similar patterns were revealed in options 6 and 7. In the control option and option 2 without agro-reclamation measures, the intensity of water loss also decreased. The decrease in the intensity of water loss over the years is associated with changes in the density of the soil caused by anthropogenic impact on it. First of all, with compaction by farm machines and ongoing irrigation of perennial grasses.

Authors: Spirin Yuriy , Puntusov Vladimir
Published: September 2020

In the Kaliningrad region there are about 70 % of all polder lands in Russia. On these lands with high potential fertility, it is advisable to intensive agriculture. The area for the average moisture year is an area with excessive moisture, which indicates the need to maintain the rate of drainage on agricultural land. Many different factors play a role in ensuring the drainage rate, one of which is pumping stations and pumping equipment installed on them. An important parameter in the use of pump-power equipment is energy consumption, since in this industry it is a considerable expense item. Improving the energy efficiency of pumping stations on polders is a pressing issue today. At the majority of polder pumping stations, domestic power pumping equipment is installed with excess power and head of 4–8 meters, and a new one is selected based on the maximum possible head in a given place. In the Kaliningrad region, the energy efficiency of polder pumping equipment has never been analyzed.

In this paper, a statistical processing of the geodesic pressure of water at the polder pumping stations of the Slavsk region for 2000–2002 was carried out. On the basis of these data and data on the hydraulic characteristics of pressure pipelines, the calculated water pressures were determined for the rational selection of pumping equipment. The calculation of the economic efficiency of pumps with optimal power compared with pumps of excess capacity. The results of the study can serve as a justification for the transition to the pumping equipment with less power and pressure, which will lead to a decrease in the cost of money for electricity.

Published: September 2020

The invasive species Drosophila suzukii (Matsumura, 1931), the spotted wing drosophila, was first recorded in Croatia in 2010. Since then, it has spread on Croatian territory but its presence has not yet been confirmed in the City of Zagreb. In this research population dynamics of D. suzukii was investigated in three orchards in Zagreb (Maksimir, Jelenovac, Zelenjak) in the period from 20th of March to 27th of November 2017. Feeding traps with apple vinegar were used for catching D. suzukii. The flight began in the period from 27th of June to 11th of July and lasted until 27th of November. The total pest catches were 874 specimens (Jelenovac 187, Maksimir 232 and Zelenjak 455). From September to November there was a continuous flight and a large increase in the number of caught flies, suggesting the presence of more overlapping generations. Besides the host plants, the development of the pest in this area is also enabled by suitable climatic conditions. The present population in the City of Zagreb County poses a danger to fruit producers in the Zagreb County. The results of this research are a contribution to better understanding of the population and the spread of the pest in Croatia.
The prospects of development of the citrus production in the Neretva valley in the context of contemporary tendencies
Authors: Paladin Soče Ivana , Ivić Dario , Marić Mara
Published: September 2020

In most countries of the world where citrus fruits are grown, including Croatia, several viruses and virus-like agents exist limiting the production and sale of citrus fruits. The most common among them is Citrus tristeza virus (CTV) which causes a decrease in tree fertility and lushness. The aim of this paper is to illustrate the large scale of consequences caused by the CTV in Spain during the 20th century. More than 44 million citrus trees grafted on sour orange (Citrus aurantim L) rootstock sourhad decayed over a period of 10 years due to the intensing spread of CTV. The approaches that addressed the problem of infection of large citrus growing areas in Spain will be presented. Based on the experience in Spain, this paper will show the possibilities of implementing systematic expert measures which would eradicate or minimize the presence of CTV in the area of the Neretva valley, the most important citrus growing area in Croatia. A large number of researches have been carried out on the presence and the outspread of CTV in the Neretva Valley from 2005 to 2019. During this period, the highest percentage of virus outspread was observed in 2006, when CTV was detected in 80% of the collected samples. The virus was regularly detected in the Neretva valley in all the years the research was conducted. The problem of CTV has been present for many years and the pathogen is still spreading, which indicates the need to take some measures to prevent this continuous spreading. Among the most important and effective measures is the control of viral diseases in the propagation materials and the mother blocks and planting virus-free plants in accordance with the provisions of the Ordinance on placing reproductive planting material and seedlings intended for fruit production on the market (OG 9/17, 39/20), which contain European Union Directives 2008/90 / EC, 2014/96 / EU, and 2014/98 / EU

Published: September 2020

Between 2010 and 2013, an outbreak of serotype-1 sequence type 306 (ST306) invasive pneumococcal disease (IPD) occurred primarily in remote locations of Northern and Central Australia. This is a descriptive study of the epidemiology of the outbreak using nationwide IPD surveillance data, supplemented with more detailed data held by affected jurisdictions, and of the response to the outbreak, including vaccination strategies. In the year the outbreak peaked (2011), serotype-1 IPD incidence was over 30-fold higher in the affected regions than in the rest of Australia (incidence rate ratio: 30.7 [95% CI 20.1–48.9]). The study includes 245 cases of serotype-1 IPD from the outbreak regions, with 75.5% identified as Indigenous.
No reported cases of serotype-1 IPD occurred in young children who had completed either a 10- or 13-valent pneumococcal conjugate vaccine schedule. However serotype-1 IPD did occur in older children who had previously received 23-valent pneumococcal polysaccharide vaccine.
Development of public-health-focused national IPD management guidelines, including suitable vaccine strategies for consistent use nationwide, could potentially decrease the duration and intensity of similar outbreaks in the future.

Kooperatifler aynı amaçla güçlerini birleştiren bireylerin, belediye, köy, il özel idaresi gibi kamu kuruluşlarının, dernekler, sendikalar gibi özel hukuk tüzel kişilerinin de üye olduğu, kâr amacı gütmeyen, özüne yardım, karşılıklı yardımlaşma ve dayanışmaya dayalı örgütler olup bir sermaye ortaklığı değildir. Dolayısıyla kooperatif örgütlerle sermaye ve kâr birbirlerinin tersi amaçlara sahiptirler. Konut kooperatifçiliği ise kooperatif sektörünün tek başına lokomotifi gibidir. Bu yönüyle hem ülke ekonomisine katkıları hem genel kooperatifçilik sektörü içindeki yeri hem de konut hakkı gibi bir insani hakkı eldeki tüm olanaklarla karşılamaya çalışan araçlar olması yine toplumsal dayanışmayı artırması bakımlarından son derece önemli ve gerekli olduğu ortadadır. Bu çalışmada ikibinli yılların başındaki kooperatifçilik alanından seçilen bir kamu politikası analizinin bulgularına yer verilmektedir. Kooperatifçilik hareketi belirgin olarak ilk kez, Avrupa’da, 19.yüzyılın ortalarından itibaren görülmeye başlamıştır. Bu anlamda Türkiye’deki kooperatifçiliğin ortaya çıkışı da aynı döneme rastlamakta, 1863 yılında, “Memleket Sandığı” adı altında bu yönde ilk örgütlenme gerçekleştirilmiş bulunmaktadır. İlk örgütlenme nitelik itibariyle tarım alanında olsa da benzer yapıların kısa bir süre konut alanında gerçekleştirildiği de görülmektedir. Türkiye’de konut kooperatiflerinin kuruluş ve işleyişi 1969 tarihli 1163 sayılı Kooperatifler Kanunu ile düzenlenmiştir. Kamu politikası anlamında böylesi bir geçmişi olan kooperatifçiliğin ve özelde de konut kooperatifçiliğinin bu çalışmada incelenmesinin gerekçesi özellikle ikibinli yıllardaki hızlı gelişmelerin varlığı ve etkisinin çokluğudur.

6360 Sayılı Büyükşehir Belediye Kanunu kapsamında büyükşehirlerde tüzel kişilikleri kaldırılan belde belediyeleri ve il özel idarelerinin personelleri büyükşehir belediyesi, ilçe belediyeleri ve ilgili kurumlara devredilmiştir. Devredilen personel sayısı ve devir alanının büyüklüğü ve çeşitliliği gibi faktörler, hem devir alan kuruluşlar hem de devredilen personeller açısından birtakım sorunları ve sıkıntıları beraberinde getirmiştir. Bu çalışmada son yasal düzenleme ile büyükşehirlerden biri olan Trabzon ilinde personellerin devir sürecinde ne gibi sorunların ortaya çıktığı ve bu sorunların devredilen personel ve kurumlar nezdinde ne gibi etkilerinin olduğu araştırılmıştır. Elde edilen bulgular ışığında, bu sürecin hem devredilen personeller üzerinde mali, sosyal ve psikolojik anlamda mağduriyetler yarattığı hem de emek ve verim kaybı, atıl personellerin varlığı ve devlet kaynaklarının heba olması gibi olumsuzluklara yol açtığı görülmüştür. Çalışmada örnek olay yöntemi kullanılmıştır. Veri toplama yöntemleri olarak doküman incelemesini ve görüşme verilerini içeren nitel veri toplama teknikleri kullanılmıştır.

Vatandaşların yerel nitelikteki ihtiyaçlarının etkili, verimli ve sürekli olarak giderilmesinde mahalli idareler sürekli olarak kendisini değiştirmek ve dönüştürmek durumundadır. Öyle ki içerisinde bulunduğumuz yüzyılın bilişim teknolojisi çağı olduğu göz önünde bulundurulduğunda devingen bir şekilde ilerleyen küresel çevreye bağlı olarak yerel yönetimler de etkilenmektedir. Yönetimdeki yeni eğilimlerin gerisinde kalınmaması ve halkın ihtiyaç duyduğu hizmetlerin kesintiye uğramaması açısından bir takım yöntemler kullanılmaktadır. Bu hizmet sunum yöntemlerinden biriside e-belediyecilik uygulamalarıdır. Zira E-devlet uygulamalarının önemli bir tamamlayıcısı olan e-belediye hizmetleri yerel yönetimlerde kendisine uygulama alanı bulmuştur. Çalışmanın amacı, yerel yönetimlerin kamu hizmeti sunma yöntemleri arasında yer alan e-belediyecilik uygulamalarını ele almaktır. Bu kapsamda; Kocaeli, Malatya, Kayseri ve Gaziantep Büyükşehir Belediyelerinin belediyecilik uygulamaları, söz konusu belediyelerin web sayfaları üzerinden incelenmiştir. Elde edilen verilere-belediyecilik uygulamaları açısından karşılaştırmalı olarak analiz edilmiştir.

Türkiye’de yerel yönetimler diğer devletler ile kıyaslandığında daha geç bugünkü anlamına kavuşmuştur. Tanzimat dönemi Osmanlı Devleti’nde bugünkü manada yerel yönetimlerinde ortaya çıktığı dönemdir. Üniter devletlerde kamusal mal ve hizmet sunumu merkezi yönetim ile yerel yönetimler arasında paylaşılmaktadır. Federal devletlerde ise federal devlet, federe birimler ve yerel yönetimler mal ve hizmet sunumunu gerçekleştirmektedirler. Birçok batılı devlette yerel yönetimler sivil toplum örgütü olarak ortaya çıkmıştır. Yerel yönetimlerin geçmişi ise orta çağa kadar uzanmaktadır. Ülkemizde ortaya çıkışı ve gelişimi ise kendine özgüdür. Osmanlı Devleti’nde de yerel hizmetleri yürüten birimler vardı ancak bu birimler Osmanlı idari sistemi içinde kendine has kurumlardı. İngiltere’de yerel yönetimin ortaya çıkışı ve gelişimi ülkemizde ortaya çıkışı ve gelişimi farklı özellikte olduğu için mevcut durumda da birçok farklılıkları bünyelerinde taşımaktadırlar. Çalışmanın amacı eski ve köklü bir yerel yönetim geleneğine sahip olan İngiltere’deki yerel yönetimler ile ülkemizdeki yerel yönetimlerin karşılaştırmalı olarak hukuki ve örgütsel boyutlarının ele alınmasıdır. Çalışma literatür taramasına dayalı bir nitel araştırmadır. Karşılaştırma yapılmıştır.
An Alternative Strategy for Sustaining Innovations of Incumbent Firms

Published: September 2020

Innovation is a prominent phenomenon that enables a firm to gain a competitive advantage against its rivals. However, this does not mean that being innovative allows a firm to perform better. Although innovation has been investigated in the literature, the types of innovations still remain esoteric. As discussed in the literature, there are different kinds of innovations. Different kinds of innovation require different kinds of business models and may have varying impacts on consumer product decisions. First, this study seeks to highlight the distinction between sustaining and disruptive innovations. Second, this study offers a conceptual framework for the antecedents of sustaining innovations. Theoretical and practical implications are discussed in the light of observations.

Atherosclerosis is a major reason for the high morbidity and mortality of cardiovascular diseases. Macrophage inflammation and foam cell formation are the key pathological processes of atherosclerosis. Ginsenoside compound K (CK) is a metabolite derived from ginseng. CK has anti atherosclerotic effect, but the molecular mechanism remains to be elucidated. We aim to explore the protective effect of CK against ox-LDL-induced inflammatory responses and foam cells formation in vitro and explore its potential mechanisms. Through the results of oil red O staining, Western blot, and qPCR, we found that CK significantly inhibited the foam cell formation, reduced the expression of SR-A1 and increased ABCA1 and ABCG1 expression. In addition, CK increased the number of autophagosomes and upregulated the LC3II/LC3I ratio and the expressions of ATG5 and Beclin-1 but decreased p62 expression. Moreover, CK significantly inhibited the NF-κB, p38, and JNK MAPK signaling pathway. Altogether, CK attenuated macrophage inflammation and foam cell formation via autophagy induction and by modulating NF-κB, p38, and JNK MAPK signaling. Thus, CK has potential as a therapeutic drug for atherosclerosis.
The Use of Dewpoint Hygrometry to Measure Low Water Potentials in Soilless Substrate Components and Composites

Plant water availability in soilless substrates is an important management consideration to maximize water efficiency for containerized crops. Changes in the characteristics (i.e., shrink) of these substrates at low water potential (<−1.0 MPa) when using a conventional pressure plate-base can reduce hydraulic connectivity between the plate and the substrate sample resulting in inaccurate measures of water retention. Soilless substrate components Sphagnum peatmoss, coconut coir, aged pine bark, shredded pine wood, pine wood chips, and two substrate composites were tested to determine the range of volumetric water content (VWC) of surface-bound water at water potentials between −1.0 to −2.0 MPa. Substrate water potentials were measured utilizing dewpoint hygrometry. The VWC for all components or composites was between 5% and 14%. These results were considerably lower compared to previous research (25% to 35% VWC) utilizing conventional pressure plate extraction techniques. This suggests that pressure plate measurements may overestimate this surface-bound water which is generally considered unavailable for plant uptake. This would result in underestimating available water by as much as 50%.
