Examining Power Quality Challenges in Photovoltaic-Grid Integration: A Critical Review

With the massive growth of photovoltaic (PV) installations worldwide, the impact of integration between PV and the grid is becoming a serious issue and requires immediate attention. This is due to the intermittent power that the PV itself generates. The quality of the power can affect the stability of the system, the protection equipment, and the energy efficiency, which imposes a financial issue. This literature review will present the most frequently encountered problems when PV integrates with the grid, namely power quality issues, particularly on the distribution network. Problem-solving will also be presented as a reference for future PV development. It discusses several ways to handle power quality problems, depending on the factors influencing power quality. One of the proven ways is to use a modern inverter equipped with features that suit the system's needs. However, the discussion in this paper is limited to the issues of power quality and voltage generated by PV integrated into the grid. Future studies can discuss other technical issues, such as protection, feeder losses, and other problems that may arise in the future.

Deodorizing bacterial consortium: community analysis of biofilms and leachate water collected from an air biofiltration system in a piggery.

Intensive livestock production is a source of water, soil, and air contamination. The first aspect that negatively affects the quality of life of residents in the vicinity of piggeries is malodorous aerosols, which are not only responsible for discomfort but can be an etiological factor in the development of various diseases during prolonged exposure. One of the proven and efficient ways to counteract odor emissions is the usage of air biofiltration. The purpose of this study was to qualitatively analyze the bacterial community colonizing the biofilm of a biofilter operating at an industrial piggery in Switzerland. The study material consisted of biofilm and leachate water samples. The microbiological analysis consisted of DNA isolation, amplification of the bacterial 16S rRNA gene fragment (V3-V4), preparation of a library for high-throughput sequencing, high-throughput NGS sequencing, filtering of the obtained sequencing reads, and evaluation of the species composition in the studied samples. The investigation revealed the presence of the following bacterial genera: Pseudochelatococcus, Methyloversatilis, Flexilinea, Deviosia, Chryseobacterium, Kribbia, Leadbetterella, Corynebacterium, Flavobacterium, Xantobacter, Tessaracoccus, Staphylococcus, Thiobacillus, Enhydrobacter, Proteiniclasticum, and Giesbergeria. Analysis of the microbial composition of biofilters provides the opportunity to improve the biofiltration process.

CRPD frontiers in movement disorders Therapeutics: From evidence to treatment and applications: Addressing Patients’ Needs in the Management of the Ataxias

The genetic ataxias have no cures and no proven ways to delay progression (no disease-modifying therapies). The acquired ataxias may have treatments that address the underlying cause and may slow or stop progression, but will not reverse damage already sustained. The idiopathic ataxias (of unknown genetic or acquired cause) also have no proven disease-modifying therapies. However, for all patients with ataxia of any cause, there is always something that can be done to improve quality of life—treat associated symptoms, provide information and resources, counsel patient and family, help with insurance and disability concerns, be available to listen and answer the many questions they will have.

Effect of Electric Field on α-Synuclein Fibrils: Revealed by Molecular Dynamics Simulations

The self-association of amylogenic proteins to the fibril form is considered a pivotal factor in the pathogenesis of neurodegenerative diseases, including Parkinson's disease (PD). PD causes unintended or uncontrollable movements in its common symptoms. α-synuclein is the major cause of PD development and thus has been the main target of numerous studies to suppress and sequester its expression or effectively degrade it. Nonetheless, to date, there are no efficient and proven ways to prevent pathological protein aggregation. Recent investigations proposed applying an external electric field to interrupt the fibrils. This method is a non-invasive approach that has a certain benefit over others. We performed molecular dynamics (MD) simulations by applying an electric field on highly toxic fibrils of α-synuclein to gain a molecular-level insight into fibril disruption mechanisms. The results revealed that the applied external electric field induces substantial changes in the conformation of the α-synuclein fibrils. Furthermore, we show the threshold value for electric field strength required to completely disrupt the α-synuclein fibrils by opening the hydrophobic core of the fibril. Thus, our findings might serve as a valuable foundation to better understand molecular-level mechanisms of the α-synuclein fibrils disaggregation process under an applied external electric field.

Estimation of the moisture content, volatile matter, ash content, fixed carbon and calorific values of saw dust briquettes

“One way of making efficient use of existing resources is briquetting. Briquetting involves collecting combustible materials that are not usable due to lack of density, and compressing them into solid fuels of convenient shape that can be burnt like wood or charcoal”. “Biomass briquette is one of the proven ways of generating energy from waste”. “Fossil fuels, wood fuels and natural gas are the major sources for energy in Nigeria today”. “The excess use of these fuels will lead to serious environmental issues like global warming, air pollution and deforestation”. “This work is focused on estimating the heating values of sawdust briquettes to ascertain its suitability for domestic use and small-scale industrial cottage application”. “The results obtained shows that average percentage moisture content is 5.04%, average percentage volatile matter is 10.80%, average percentage ash content is 3.85%, average percentage fixed carbon is 80.95% and average percentage calorific value is 26918.02KCal/Kg. These results indicate that the briquettes made from sawdust have high heating value enough for domestic use and small-scale industrial cottage applications”.

Evaluation of Shear Bond Strength a Composite Resin to I-CON Fissure Sealant with Different Surface Treatment

Introduction: Fissure sealants are one of the most proven ways to prevent tooth decay. These materials may remain on the tooth for a long time, and other areas of the tooth may decay. The purpose of this study was to present the best method for surface preparation a fissure sealant material (Icon) and composite restoration Materials and Methods: In this experimental laboratory study, 40 samples of composite restorative material were prepared in 4 groups of 10 discs of 6 mm in diameter and 2 mm in height. Total etch bonding agent was used in the first, second and third groups without surface preparation, with the use of drills and 37% phosphoric acid, and after drilling, respectively. In the fourth group, self-etch bonding agent was used after drilling. After that, Icon resin material was placed on the surface of the composite in a disc of 4 mm with height of 2mm in diameter and was cured. When the samples were thermocycled and incubated, their bonding strength was evaluated with Instron testing machine. Data were analyzed by one-way variance statistical ANOVA tests, Tukey test (p value < 0.05). Results: The mean value of bond strength of Icon to resin composite was significantly different among the 4 groups (p value < 0.05). The fourth group presented the greatest bond strength value while the third group had the lowest bond strength. Conclusion: When repairing fissure sealant, particularly Icon using resin composite, the best results of bond strength are achieved through surface roughening with drills and the application of self-etch bonding agents with a mild pH. Acidic etching agents (37% Phosphoric acid), however, have probably destructive effects on bond strength.

IS YOUR COMMUNITY-BASED HEALTH PROMOTION PROGRAM EVIDENCE BASED AND READY FOR DISSEMINATION? HERE’S HOW TO FIND OUT

Evidence-based programs (EBPs) offer proven ways to promote health and prevent disease among older adults in their communities. EBPs are based on rigorous study of the effects of specific interventions or model programs, demonstrate consistently positive changes in important health-related and functional measures, and have tools in place to maintain program access, quality, and efficiency across diverse settings. The University of North Carolina at Chapel Hill’s Center for Health Promotion and Disease Prevention (UNC HPDP), in partnership with the Evidence-Based Leadership Collaborative (EBLC), has established a review process and Review Council to identify new community programs that meet the evidence-based program criteria established by the Administration for Community Living (ACL), one of the chief U.S. federal agencies responsible for aging programs. Approved programs are then eligible for Older Americans Act Title III-D and other discretionary funding to support organizations that deliver EBPs to improve older adult health. The review process assesses the effectiveness, outcomes, and evaluation of the program, information about program implementation, training, and other key elements for successful program dissemination. The Review Council consists of national leaders with expertise in program research, evaluation, and implementation. The review process is supported by the ACL-funded National Chronic Disease Self-Management Education and Falls Prevention Resource Centers. This session will describe the ACL evidence-based health promotion program criteria that must be met for approval; an overview of the review process; and how researchers can submit their programs for review. Time will be allowed for questions, discussion, and research to practice implications.

Zapažanja zaposlenika - uvjet unapređivanja kulture zaštite na radu

SUMMARY: In preventing injury at work, the law provides for the application of recognized professional rules and in practice proven ways of eliminating or reducing workplace risks. Safety Hazard Observation Cards (SHOC) have proven to be a useful tool to increase employees’ awareness and attention to unsafe actions and unsafe conditions. However, in Croatian practice, it is difficult to persuade employees to write down their observations and sign them. Over the years, in the Saipem SpA Croatian Branch, we encountered employees’ reluctance towards filling the SHOC-cards. To motivate employees, we have organized events in which we set up hazards that employees should locate in the allotted time, and write and describe them on the forms, i.e. cards provided for the purpose. The employee who first identified all "set up hazards" was awarded a prize. During these events, the number of SHOC-cards written not only exceeded their annual "production" but also helped to recognize and eliminate many other hazards, and the employees were pleased to participate. The event is organized several times a year to enhance awareness of the importance of filling SHOCs and strengthening efforts to change the safety culture.
