Published: December 2019

BackgroundPhosphate is an essential plant macronutrient required to achieve maximum crop yield. Roots are able to uptake soil phosphate from the immediate root area, thus creating a nutrient depletion zone. Many plants are able to exploit phosphate from beyond this root nutrient depletion zone through symbiotic association with Arbuscular Mycorrhizal Fungi (AMF). Here we characterise the relationship between root architecture, AMF association and low phosphate tolerance in strawberries. The contrasting root architecture in the parental strawberry cultivars ‘Redgauntlet’ and ‘Hapil’ was studied through a mapping population of 168 progeny. Low phosphate tolerance and AMF association was quantified for each genotype to allow assessment of the phenotypic and genotypic relationships between traits.ResultsA “phosphate scavenging” root phenotype where individuals exhibit a high proportion of surface lateral roots was associated with a reduction in root system size across genotypes. A genetic correlation between “root system size” traits was observed with a network of pleiotropic QTL were found to represent five “root system size” traits. By contrast, average root diameter and the distribution of roots appeared to be under two discrete methods of genetic control. A total of 45 QTL were associated with plant traits, eight of which were associated with root depth that explained 68 % of the observed variation. Investigations into the relationship between AMF association and root architecture found that a higher root density was associated with greater AMF colonisation across genotypes. However, no phenotypic correlation or genotypic association was found between low phosphate tolerance and the propensity for AMF association, nor root architectural traits when plants are grown under optimal nutrient conditions.ConclusionsUnderstanding the genetic relationships underpinning phosphate capture can inform the breeding of strawberry varieties with better nutrient use efficiency. Solid root systems were associated with greater AMF colonisation. However, low P-tolerance was not phenotypically or genotypically associated with root architecture traits in strawberry plants. Furthermore, a trade-off was observed between root system size and root architecture type, highlighting the energetic costs associated with a “phosphate scavenging” root architecture.
An application of Altman Z-score model to analyze the bankruptcy risk: cases of multidisciplinary enterprises in Vietnam
Authors: Thanh Tung Diep , Thi Hoang Phung Vo
Published: December 2019

This study applied Altman Z-score model to assess the bankruptcy risk of a set of multidisciplinary enterprises of various types, mainly small and medium enterprises, with data taken from official financial reports of 180 enterprises in Soc Trang province. The binary logistic regression was employed to assess the impact of non-financial and financial factors on the bankruptcy risk of enterprises. The research findings showed that both the non-financial factors such as business area, types and size of the business, the educational level of managers and executors and other characteristics, and the financial factors (indicators) such as earnings before tax, net profit/equity ratio, earnings before interest and tax/total assets ratio, equity/total debt ratio, affect the bankruptcy risk of enterprises. Predicting the bankruptcy risk and measuring its determinants play an important role not only as an effective managing tool of the business, but also as evidence for policymakers to support the sustainable development of business.
Hydraulic investigation of the impact of retrofitting floating treatment wetlands in retention ponds
Authors: Khan Sher , Shoaib Muhammad , Khan Mudasser Muneer , Melville Bruce W. , Shamseldin Asaad Y.
Published: December 2019

This paper describes the laboratory experimental investigations undertaken to analyse the influence of floating treatment wetlands (FTWs) on the hydraulic performance of a stormwater retention pond. Two experimental series were conducted, each focussed on investigating the influence of placing an FTW in a pond with firstly the inflow entering the retention pond from an inlet positioned 0.25 m offset from the longitudinal axis of the pond, and secondly the inlet positioned at the longitudinal axis of the pond. For both series of experiments, tests were undertaken at 1 l/s and 1.5 l/s, and with and without an artificial FTW installed. This study is the first to investigate the hydraulic impact of FTWs and their root systems on the performance of stormwater retention ponds. The results presented in this study suggest that FTWs are a viable method to minimise hydraulic inefficiencies, thereby increasing retention time and optimising hydraulic performance of stormwater retention ponds. The results highlight the importance of plant root characteristics. The optimal arrangement of root length is LR/DP = 0.5, where LR = root length and DP = pond depth. The results also indicate that the spatial variability of vegetation has a significant impact on the hydraulic performance of the pond.
Application of polymeric ferric sulfate combined with cross-frequency magnetic field in the printing and dyeing wastewater treatment
Authors: Gu Shiguo , Lian Fei , Yan Kejun , Zhang Wei
Published: December 2019

Polymeric ferric sulfate (PFS) was pretreated with a self-made alternating frequency magnetic field for coagulation printing and dyeing (PD) wastewater treatment. The effects of PFS dosage, magnetization intensity, frequency, and time on the removal of chemical oxygen demand (COD), color and turbidity of PD wastewater were investigated. The results indicated that the magnetized PFS significantly improved the removal efficiency in wastewater treatment. When the initial COD, color and turbidity of printing and dyeing wastewater was 464 mg/L, 180 degrees, and 54.8 NTU respectively, the maximum removal rate of COD, color and turbidity was 87.9%, 80.1%, and 95.2% respectively, under the condition of cross frequency magnetic field magnetization PFS. Moreover, the PFS treatment combined with cross-frequency magnetic field could greatly reduce the pollution of iron ions released from iron-based coagulant during wastewater treatment. Characterization of magnetized PFS flocculant by fourier transform infrared spectroscopy, ultraviolet and visible spectrophotometry, and scanning electron microscopy suggested that magnetic crystal with larger size can be formed on the surface of PFS particles.
An Insight into the Discovery of Potent Antifilarial Leads Against Lymphatic Filariasis
Authors: Boniface Pone Kamdem , Elizabeth Ferreira Igne
Published: December 2019

Background and Objectives:

Lymphatic filariasis is a neglected tropical disease caused by
infection with filarial worms that are transmitted through mosquito bites. Globally, 120 million people
are infected, with nearly 40 million people disfigured and disabled by complications such as severe
swelling of the legs (elephantiasis) or scrotum (hydrocele). Current treatments (ivermectin, diethylcarbamazine)
have limited effects on adult parasites and produce side effects; therefore, there is an urgent
to search for new antifilarial agents. Numerous studies on the antifilarial activity of pure molecules
have been reported accross the recent literature. The present study describes the current standings of
potent antifilarial compounds against lymphatic filariasis.

Methods:

A literature search was conducted for naturally occurring and synthetic antifilarial compounds
by referencing textbooks and scientific databases (SciFinder, PubMed, Science Direct, Wiley,
ACS, SciELO, Google Scholar, and Springer, among others) from their inception until September
2019.

Results:

Numerous compounds have been reported to exhibit antifilarial acitivity in adult and microfilariae
forms of the parasites responsible for lymphatic filariasis. In silico studies of active antifilarial
compounds (ligands) showed molecular interactions over the protein targets (trehalose-6-phosphate
phosphatase, thymidylate synthase, among others) of lymphatic filariasis, and supported the in vitro
results.

Conclusion:

With reference to in vitro antifilarial studies, there is evidence that natural and synthetic
products can serve as basic scaffolds for the development of antifilarial agents. The optimization of
the most potent antifilarial compounds can be further performed, followed by their in vivo studies.

Authors: Bai Yajun , Li Bin , Xie Jing , Chen Xufei , Cheng Shu , Bai Yujun , Sun Ying , Qin Fanggang , Liang Jing , Ding Yanrui , Zheng Xiaohui
Published: December 2019

Background:

Our previous studies showed that α-asaronol was a potential antiepileptic
candidate. Here, twelve O-terminus modified ester derivatives of α-asaronol were designed, synthesized
and evaluated their anticonvulsant activity.

Methods:

All synthetic compounds were subjected to three animal models of seizure (MES, scPTZ
and sc3-MP models) combined with neurotoxicity test, as well as the LDH inhibitory test. Furthermore,
GABAA Receptor modulation and pharmacokinetic evaluation of compound 4k were also
performed.

Results:

Five compounds (4a, 4b, 4d, 4e and 4k) showed significant anticonvulsant properties at the
dose of 30-300 mg/kg in MES and scPTZ test, but weak activity in sc3-MP model. Meanwhile, 4a,
4b, 4d and 4k showed good LDH inhibitory activity in vitro. Specifically, 4k was the best compound
in above evaluation, and better than that of α-asaronol and reference compound (stiripentol).
In addition, 4k could increase chloride ion influx by modulating GABAA receptor α1β2γ2 subtype
with EC50 of 48.65 ± 10.31 μM and showed good PK profiles in rats with moderate oral bioavailability
(51.5%).

Conclusion:

These results suggested 4k possesses potential effectiveness in treatment of therapyresistant
seizures and is expected to be developed as a novel molecule for safer and efficient anticonvulsants
having neuroprotective effects as well as low toxicity.

Authors: Lone Irfan H. , Aslam Jeenat , Radwan Nagi R.E. , Akhter Arifa , Bashal Ali H. , Shiekh Rayees A.
Published: December 2019

Background:

he properties of materials depend on the way of construction and the arrangement
of atoms and molecules. Therefore, it is very important to know synthesis methods for the
preparation of novel materials as per their desired structure. The low-temperature synthesis methods,
such as polymeric citrate precursor and sonochemical methods are efficient enough to control the
preparation of novel nanoparticles with morphological differences that leads to the novel devices
with desired technological performances. These methods are simple, very less expensive and are easy
to handle to operate for the synthesis of nanoparticles as per the expected morphology and dimensions.

Methods:

Polymeric citrate precursor method, a chelate-based method involves the reaction between
mixed cations with citric acid, and then these cations are cross-linked with the help of ethylene glycol
for the esterification process. Gel composites were heated which burns the organic moieties leaving
behind the nanoparticles, and burning gels becomes essential for the reduction of nanoparticles. The
sonochemical method, on the other hand, uses ultrasonic the irradiation results. The acoustic cavitation
and high intensity ultrasound has been exploited for the preparation of different series of nanoparticles.

Results:

Commonly known for polymeric citrate method as Pechini gel pyrolysis method gives the
evidence of versatile and elegant method for the synthesis of nanoparticles. The sonochemical method
provides an unusual route of nanoparticle fabrication without bulk and that too with low temperature
and pressure or less reaction time. These two methods have better control for the desired shape
morphology and size and provide many opportunities for the use of these prepared nanoparticles in
various aspects of science and technology.

Conclusion:

Polymeric citrate precursor and sonochemical methods are efficient to reduce to promote
desirable reaction conditions and reduce the metal ions for the fabrication of nanoparticles. The
prepared nanoparticles by using such low-cost elegant methods are uniform with a small size distribution,
reproducible with good yield as per the demanded applications.

Authors: Thangavelu Sivakumar , Sonai Veeramani , Malaisamy Pandi , Nallakannu Senthil Madasamy , kumar Rakesh
Published: December 2019

Background:

In 21st century one of the emerging issues is to secure the information stored and communicated in digital form. There is no assurance that the data we have sent may be hacked by any hacker and the data we have sent may reach correctly to the receiver or not. Thus, confidentiality, integrity, and authentication services play major role in Internet communication. Encryption is the process of encoding messages in such a way that only authorized parties can read and understand after successful decryption. Several data security techniques have been emerged in recent years, but still there is a need to develop new and different techniques to protect the digital information from attackers. This paper provides a new idea for data encryption and decryption using the notion of binary tree traversal to secure digital data.

Objective:

To develop a new data encryption and decryption method using the notion of binary tree traversal to secure data.

Methods:

The proposed method uses both transposition and substitution techniques for converting plaintext into ciphertext. The notion binary tree in-order traversal is adapted as transposition and Caesar cipher technique for substitution.

Results:

From the result, it observed that the repeating letters in the plaintext are replaced with different cipher letters. Hence, it is infeasible to predict the plaintext message easily using letter frequency analysis. From the experimental result, it is concluded that the proposed method provides different ciphertext for the same plaintext message when the number of round varies. The time taken by the proposed method for encryption is very less.

Conclusion:

A simple encryption method using binary tree in-order traversal and Caesar cipher is developed. Encrypting data using binary tree traversals is a different way while compared with other traditional encryption methods. The proposed method is fast, secure and can be used to encrypt short messages in real time applications.
Clasificación del uso de suelo y vegetación en áreas de pérdida de cobertura arbórea (2000–2016) en la cuenca del río Usumacinta
Authors: Peralta-Carreta Candelario , Gallardo-Cruz J. Alberto , Solórzano Jonathan V. , Hernandez-Gómez Matías
Published: December 2019

A escala mundial, la mayor parte de los estudios sobre la pérdida de cobertura arbórea se enfocan en cuantificarla por medio de técnicas de percepción remota. Dichas estimaciones frecuentemente omiten la información del tipo de uso de suelo y vegetación, por lo que limitan el entendimiento de las pérdidas ocurridas para cada una de estas clases. Con el fin de conocer cuáles han sido las comunidades vegetales más afectadas por el proceso de pérdida de cobertura arbórea en el periodo 2000–2016 en la cuenca del Usumacinta en este estudio se analizaron de manera simultánea dos fuentes de información disponibles: la Serie II de Uso de suelo y vegetación del Instituto Nacional de Estadística y Geografía de México (Inegi, 2001) y la evaluación del cambio en la cobertura forestal a escala global (Hansen et al., 2013). Los resultados indican que de las 347 317.68 ha de cobertura arbórea perdidas entre el 2000 y 2016 en la cuenca, 62% correspondió a tres categorías: la selva alta perennifolia (SAP, 26%), uno de los tipos de vegetación más biodiversos del país; la vegetación secundaria de selva alta perennifolia (VSSAP, 19.1%) y el pastizal cultivado inducido (PCI, 17.0%), una clase fuertemente transformada por las actividades antrópicas. Las pérdidas de la SAP y de la VSSAP se concentraron principalmente en la porción media y media/alta de la cuenca, respectivamente, mientras que la del PCI en la parte baja. De manera opuesta, las clases de vegetación con menor pérdida de cobertura arbórea fueron también las menos representadas en superficie en la cuenca. Los resultados derivados de este trabajo servirán para identificar los sistemas más amenazados y orientar las acciones de conservación en la región.

Authors: Kurniawan Redite
Published: December 2019

Elementary has emerged as an inclusive school in Indonesia recently. Eventhough some of them haven’t shown the proper planning of inclusive learning, learning process, and optimal outcome learning for special needs students. Moreover if the learning process connected with religious value in Islamic elementary school. How the implementation of religious value can be involved in Individual Education Program (IEP) in elementary school?  This paper discuss about Individual Education Program (IEP) based on religious value which conduct as a particular curriculum for special needs students (SNS). Investigation for specific purpose on this study headed to Islamic values development in SNS. The data collected from interviews, documents, and observation from Ar-Roihan Inclusive Islamic Elementary School Lawang that has been pointed as inclusive pilot project since 2016. Prior study has shown the benefit of inclusive school for disability children, but it’s not focus on how Islamic values influence in their daily activities. Developed from data collected, the IEP program has reflected how the SNS used to and motivated to Islamic way in their daily activities, such as pray together, recite holy Qur’an, and respect for each other.

The present study attempts to present the evidence of how learners of English as Second Language perform the target language by involving 20 participants from one of state universities in Yogyakarta. The participants are sitting in the first semester majoring English Literature. In investigating the target language performance this study used a writing assignment namely recount text in order to identify language development in relation to grammar acquisition comitted by the learners. Errors made by the learners tend to show interlanguage that the learners performance gains immediate status between native language and target language. The study found that the leaners explored 15 grammar aspects including past tense, modality, to + infinitive , gerund, make, passive voice ,sentence elements, prepositions, articles, collocations, singular and plural nouns, pronouns, relative pronouns, question word order and native language transfer.  The approximate cause of the errors are overgeneralization , learning strategy and native transfer. Moreover, overgeneralization becomes the most frequent in making errors that is by consistently using past tense in dealing with verbs. Thus, it is suggested that the teacher is necessary to sharpen the material spesifically based on actual evidence of learners’ performance in order to accomodate what the learners need.
