Agrosharing as strategic vector of Education, Science and Business for sustainable development

The study substantiates necessity for joint development of scientific structures, educational system and business sector to ensure their sustainability. The aim of the article is to define preconditions, challenges and advantages for joint development of educational, scientific and business areas in agrosharing system as general consumption of material goods, natural resources and intellectual property in agricultural sector. Forms and problems of cooperation of this system’s main constituents are given. The study determines preconditions that make impossible segmental sustainable development of education, science and business. They lie in lack of material resources, possibilities for transferring technologies into business, employees’ motivation of science and educational area and business structures’ awareness of possibilities to leverage manufacturing processes. It is obvious that agrarian sector requires special attention toward well-coordinated work of the system, which includes expensive constantly updated material and technical base, narrow focus of each individual business, necessity for practical circular monitoring research and constantly updated IT platforms for planning and anticipating agrarian businesses. To solve this problem, we have suggested agrosharing as a model of joint consumption of goods, natural resources, material and technical base and intellectual property in interactive system of education, business and science in agrarian sector.
Designing for Tussle in Encrypted DNS

Recent concerns over the privacy implications of the Domain Name System (DNS) have led to encrypting DNS queries and responses through protocols like DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT). Although the trend towards encryption is a positive development, the accompanying centralization of the DNS has fomented tussles involving ISPs, browser and device vendors, content delivery networks, and users. This paper articulates several current DNS tussles and offers principles to guide system design and implementation such that all stakeholders in the space could participate. We argue that refactoring name resolution in a stub resolver that is separate from devices and applications can preserve the benefits of encrypted DNS while satisfying other architectural desiderata, including performance, resilience, and privacy.
5-Aminolevulinic Acid-induced Salt Tolerance in Strawberry: Possible Role of Nitric Oxide on Interception of Salty Ions in Roots

Background: 5-Aminolevunic acid (ALA), as a natural non-protein amino acid and the first essential precursor of tetrapyrrole biosynthesis in all living bodies, has been suggested to improve salt tolerance of plants. In the previous work, we reported that ALA induces H2O2 accumulation in roots of strawberry, which is involved in up-regulating Na+ transporter gene expressions to intercept Na+ in roots with less upward transport. However, the signal route is not clear.Results: In this study, we propose that nitric oxide (NO) is involved in ALA signaling cascade. Therefore, we applied sodium nitrosylpentacy (SNP, NO donor), Na2WO4 (NO biosynthetic inhibitor), and 2, 4-carboxyphenyl-4, 4, 5, 5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO, NO scavenger) to the culture solution when strawberry (Fragaria × ananassa Duch. cv. ‘Benihoppe’) was stressed by 100 mmol L-1 NaCl with or without exogenous ALA. The results reveal that salinity greatly impaired plant growth while 10 mg L-1 ALA or 10 µM SNP ameliorated the inhibition. When 5 µM Na2WO4 or cPTIO was co-treated, the ALA-improved salt tolerance was almost completely eliminated. This suggests that ALA-improved salt tolerance is dependent on NO presence. We found that salinity caused NO, H2O2, Na+ and Cl- increases in the whole plants, while ALA induced additional increases in roots but significant depressions in leaves. These tissue-specific responses to ALA are important for plant salt tolerance. Conclusion: We propose that the regulation of ALA in roots is critical, which is mediated through NO and then H2O2 signal to up-express genes related with Na+ and Cl- transport, selectively retaining Na+ and Cl- in roots with less upward transport. The hypothesis can reasonably explain how ALA-treated plants cope with toxic ions under salinity.
Application of Coal Fly Ash in Air Quality Management

Although, coal fly ash is recognized as an environmental pollutant, it can be used for the removal of various gaseous pollutants under controlled conditions. A lot of work has been conducted worldwide for the utilization of fly ash for various applications. It has been found from the literature that fly ash possesses potential application in the management of air quality. The literature data revealed that fly ash can be utilized for the removal of NOx, SOx, mercury, and other gaseous pollutants from air and other sources. Fly ash can be used as a promising sorbent for the removal of various types of air pollutants; however, further research need to be taken in the laboratory and pilot plant scale. It is also indicated that fly ash contained approximately 10–12% of unburned component and these unburned components may have an important role in their removal capacity. In this article, the application of fly ash in the removal of SOx, NOx, mercury, gaseous organics, and other impurities have been discussed an.
Production of Bio char with High Mineral Content from Oil Palm Biomass

Carbonization of oil palm empty fruit bunch (OPEFB) biomass for the production of high mineral content bio char under an uncontrolled carbonization temperature and controlled air flow rate was studied using a pilot-scale brick carbonization reactor. The maximum temperature during the carbonization process was found to be in the range of 543 to 564 degree Celsius at exhaust gas flow rate of 36 m{sup 3}/ hr. All minerals (for example P, K ,Mg, Ca, Na, Mn, Fe, Cr, AI) showed an increased from the feedstock concentration up to 300 %. The concentration of heavy metal extracted from OPEFB bio char was lower than listed ceiling permitted levels. This proposed system without electrical control and heating source is preferable to the industry due to its simplicity, ease of operation and low energy requirement making it suitable for OPEFB bio char production for mulching purposes with more than double the mineral content compared to raw OPEFB biomass.

Rural Road Infrastructural Challenges: An Impediment to Agricultural Development in Idanre Local Government Area of Ondo State, Nigeria

Accessibility to the rural area by road is a key factor in achieving Sustainable Development Goals in pursuance of optimal survival these areas. Various rural development policies instituted in Nigeria to alleviate the condition of rural dwellers and to sustain agricultural development, yet the smooth accessibility desires of several rural areas impaired by poor rural road infrastructure. The resultant effect of this is low agricultural productivity in rural areas and food insecurity. Rural communities in developing countries are mostly disconnected from the major roads and public transport services that should provide them access to the economic and social opportunities in cities. To this end, the research examined how road infrastructural challenges have impeded the development of agriculture in Idanre Local Government Council Areas, Ondo State, Nigeria. A structured questionnaire was purposively and randomly administered to collect data from a total of 200 farmers across 20 villages in the study area. Analysis of data for the information retrieved from the respondents were carried out with aid of descriptive statistics while stepwise regression examination was done to test the hypothesis. Findings revealed a high cost of transportation and irregular transport services as a result of the poor state of the roads in the study area have hindered effective agricultural development. Results also indicated that motorcycles were the dominant means of transportation in the LGA. This among others resulted in an increasing rate of post-harvest loss because of the restrictive capacity of motorcycle and high cost of transportation. The study recommended the construction and rehabilitation of dilapidated roads infrastructure to enhance agricultural development in the study area.
Process Operational Safety via Integrated Design of Control and Safety Systems

Author(s): Zhang, Zhihao | Advisor(s): Christofides, Panagiotis D | Abstract: Process safety is a crucial issue in the area of process systems engineering as accident prevention is a top priority in process operations. Operational safety needs to be directly incorporated into control system and safety system to handle disturbances and device failures in the chemical processes. Motivated by the above considerations, this dissertation provides various methods and case studies to demonstrate the integration of safety considerations into controller design. First, we present the dynamic interactions between feedback control and safety systems, and elaborate on the effectiveness by showing applications to a continuous stirred tank reactor (CSTR) and a high-pressure flash drum separator with both classical and model-based controllers. Then, a Safeness Index function is developed to be utilized as a constraint in model predictive control (MPC) design to provide coordination between control and safety systems. The proposed Safeness-Index based MPC is applied to a flash drum and an ammonia production process to enhance process operational safety. Moreover, a large-scale ammonia process network is studied with respect to process operational safety with multiple model predictive controllers to avoid extremely high temperature in the presence of significant disturbances. Additionally, the 2015 explosion accident at the refinery operated by ExxonMobil in Torrance, California is analyzed. A control-based approach is presented for how the accident could have been potentially avoided by simulating accident conditions in the fluid catalytic cracking unit (FCC). Lastly, a method for combining neural network models with first-principles models is presented. The improved performance of this hybrid model is demonstrated in both real-time optimization (RTO) and MPC of a CSTR and a distillation column. Aspen Plus Dynamics, a commercial process simulation software, is integrated with Matlab to carry out the above simulations for large-scale chemical processes to demonstrate the applicability and effectiveness of the proposed control methods.
MIMODSA:Non-Pre-emptive Scheduling in Cognitive Radio Ad-Hoc Networks (CRAHNs)

Resource allocation and proficient practice of spectral frequencies to the cognitive consumers is remaining as a major apprehension in cognitive radio networks. Dynamic resource allocation can resolve the numerous research trials in CRAHNs with respect to spectrum access, allocation, and sharing. In the view of aforementioned research issue, dynamic resource allocation using non-pre-emptive scheduling is proposed by a combination of spectrum assignment and prioritization scheduling of secondary users in a cognitive wireless environment. This research work is proposing an algorithm for multiple input multiple output dynamic spectrum allocation using non-pre-emptive scheduling (MIMO-DSANPS) in CRAHNs is proposed. The simulation is performed on heterogeneous wireless environment and comparing our proposed algorithm with existing Dynamic Resource Allocation (DRA-CRN) algorithm and comparing the quality of service parameters, throughput, interference with sub-channels, packet drop and delay evaluation. As per the simulation study, the existing algorithm is improved with our proposed MIMO-DSANPS by 17% efficient in accessing the spectrum.
TGM2 Has Potential to Be A Prognostic Factor for Lung Squamous Cell Carcinoma and an Indicator of Immune Infiltrates

Background: TGM2 is a functionally diverse molecule that has multiple roles in mediating signal transduction and inflammation. However, the prognostic value of TGM2 and its correlation with tumor-infiltrating immune cells in lung squamous cell carcinoma (LUSC) remains elusive. Methods: Datasets of LUSC were downloaded from The Cancer Genome Atlas (TCGA) to analyze the expression of TGM2 in LUSC. Then, Univariable survival and Multivariate Cox analysis was used to analyze the survival effect of several clinical characteristics. The influence of TGM2 on survival of LUSC patients was evaluated by Gene Expression Profiling Interactive Analysis (GEPIA). The relationship between TGM2 and tumor-infiltrated immune cells was analyzed using the Tumor Immune Estimation Resource (TIMER). Results: TGM2 expression was remarkably lower in LUSC tissues than in the corresponding normal tissues. Low TGM2 expression was correlated with better OS in LUSC. Multivariate survival analysis demonstrated that high TGM2 expression was an independent risk factor for OS.TGM2 expression was significantly positively associated with infiltrating levels of macrophages, meanwhile was strongly correlated with various markers of immune cells, especially tumor-associated macrophages (TAMs) and T-regulatory cells (Tregs). Conclusions: TGM2 is a prognostic biomarker and correlated with immune infiltrates in LUSC.
Biodegradation of Sodium Dodecyl Sulphate and Methyl Paraben in Shampoo and Hair Dressing Salon Waste by Bacteria from Sewage Treatment Sludge

The present study investigated the biodegradation of Sodium dodecyl sulphate (SDS) and Methyl paraben (MP) both in Shampoo and Hair dressing salon wastewater using bacteria isolated from sewage treatment sludge. The biodegradation was carried out according to the OECD Guideline for ready biodegradability and was monitored by standard spectrophotometric methods. The results obtained indicated that these compounds were degraded biotically by simple bacteria identified using a Microgen Kit for bacteria characterization. Bacillus cereus, Escherichia coli and Klebsiella pnemoniae degraded 98.3% of the original SDS level in the Standard SDS solution on 7 days of incubation; Klebsiella planticola and Proteus vulgaris degraded 98.9% of the original SDS level for 10 days of incubation and 94.4% of MP on 13 days of incubation in the Shampoo solution; Vibro cholera, Pseudomonas beteli and Escherichia coli degraded 98.1% of the initial SDS level on 5 days of incubation and 90.5% of the initial MP level on 4 days of incubation; Pseudomonas aeuroginosa, Escherichia coli and Staphylococcus aureus degraded 92.0% of the MP level in the standard MP solution on 7 days of incubation while the inoculum control was found to contain Pseudomonas aeuroginosa Salmonella typhi . In conclusion, the results of this study suggested that this method of biodegradation of surfactant is cost effective and using bacteria as a biodegradation agent is environmently friendly.
Porous Graphitic Carbon Nitride: A Possible Metal-free Photocatalyst for Water Splitting

Hydrogen generation through photocatalytic water splitting with the aid of renewable solar energy is an important step toward the development of sustainable and alternative energy. In the present study, using the first-principles calculations, we have explored the s-triazine based two-dimensional porous graphitic carbon nitride (g-CN) materials as a potential photocatalyst for water splitting. For calculating the band structures more accurately, we have employed hybrid density functionals. The calculated band gap of the single layer g-CN is found to be 2.89 eV, which decreases to ∼2.75 eV in multilayered structure. To improve the visible light activity, the effect of doping with different nonmetals on the electronic structure has been investigated. Among the different dopants studied, phosphorus is found to be more effective to reduce the band gap to 2.31 eV. The band edge potentials obtained from density functional calculations are corrected for vacuum potentials. The band alignments with respect to the .

Enhanced Nucleation and Crystallization of Poly(l-lactic acid) by Immiscible Blending with Poly(vinylidene fluoride)

Effects of poly(vinylidene fluoride) (PVDF) on the non-isothermal and isothermal crystallization kinetics, crystalline structure, and spherulitic morphology of poly(l-lactic acid) (PLLA) in their immiscible blends were investigated. Both the cold and melt crystallizations of PLLA are accelerated after blending with PVDF. The crystallization rate of PLLA further increases as the PVDF content increases. PLLA does not crystallize upon cooling (10 °C/min) from the melt, while it can almost crystallize sufficiently under the same conditions after blending with 10% PVDF. PLLA crystallizes after the crystallization of PVDF in the melt crystallization process. The isothermal crystallization kinetics of PLLA in the blends was analyzed by the Avrami model. Crystallization half-time decreases and crystallization rate constant of PLLA increases after blending with PVDF. With the presence of PVDF, the spherulitic size of PLLA decreases and spherulitic number increases. Nucleation density of PLLA increases by 2–3 order.
Workflow specification and inference in some extension of allen’s interval logic.

: A workflow is an automation of a process, in which agents (people or programs) are involved in activities for solving a set of tasks in order to attain a common goal. The concept of workflow appeared in business informatics . Currently, the workflow techniques are used in many other fields of informatics (medical and bioinformatics, organization of scientific researches, computer-aided design and manufacturing, robotics et al,) Many methods and formalisms were applied for specifying workflows. Specific logical languages were used for this. In particular, temporal logics are popular as workflow specification formalisms. Allen’s interval logic is the simplest temporal logic, but only a few kinds of qualitative properties can be specified for workflows, We define a metric extension of Allen’s interval logic and show how to use it for specifying workflows . We construct an inference method for this formalism. The method is based on the analytic tableaux techniques. We also show how to use the inference method for query answering over workflows schemas and their states.
Synthesis and Study of Stable and Size-Controlled ZnO–SiO2 Quantum Dots: Application as a Humidity Sensor

This study reports a synthesis by the sol–gel method of stable and size-controlled ZnO quantum dots (QDs) embedded into a SiO2 matrix in the diameter range of 2.7–5.5 nm with strong visible emission in the blue-green region. X-ray diffraction and selected area electron diffraction techniques evidence a wurtzite structure of the prepared ZnO QDs. Transmission electron microscopy investigation highlights that the ZnO nanoparticles produced in methanol solution have a nonuniform shape. Addition of tetraethyl ortho-silicate (TEOS) in the solution at different times blocks the nucleation of the QDs and allows the control of the QD size due to a SiO2 capping. Moreover, Fourier transformed infrared analysis and X-ray photoelectron spectroscopy (XPS) were used to show the ZnO QD composition and to confirm their incorporation into the SiO2 matrix by the creation of a Zn–O–Si crossing link. A strong UV band and a weak visible band are revealed at room temperature by photoluminescence (PL) measurement for pure ZnO n.
Cluster root allocation of white lupin (Lupinus albus L.) in soil with heterogeneous phosphorus and water distribution

Abstract Cluster roots are structures formed by many plants adapted to phosphorus (P)-deficient soils. We investigated the combined influence of spatial heterogeneity in soil water and P distribution on the allocation of cluster root formation in white lupin (Lupinus albus L.). In this study, single plants were grown at a low or a high rate of water supply in containers filled with a P-poor sand to which either no P was added or which was fertilized homogeneously or heterogeneously. Furthermore, heterogeneous soil water distribution was established in half of the containers by using a finer instead of a coarser sand in a lateral third of the containers. Plant growth increased with water supply rate, but P fertilization had no influence on shoot biomass production. Although overall cluster root production decreased with increasing homogeneous P supply, localized P fertilization had no effect on cluster root allocation. However, cluster roots were preferentially allocated in the soil sections with lower water availability when overall water supply rate was low. The results suggest that overall cluster root production was a systemic response to initial plant P status, while cluster root growth was stimulated locally in drier patches when overall water supply was limiting plant growth.
