Characterization of refined papermaking pulps using hydrodynamic parameters from filtration analysis
Authors: S. LAVRYKOV S. , RAMARAO B.V.
Published: October 2019

It is often necessary to characterize papermaking pulps in order to determine the impact of refining or to predict their drainage properties. The newer methods for pulp quality analysis determine geometrical features of pulp fibers by microimaging techniques. However, features such as fiber length, coarsenes, and their distributions do not yield easily to estimation of their drainage or papermaking properties. In quantifying the impact of refining on fiber quality, it is useful to approach the rheology of pulps as an indicator of their behavior. We determined the hydrodynamic characteristics of a variety of refined pulps along with their permeability characteristics, i.e., the hydrodynamic specific surface area and the specific volume. Our method was to analyze the filtration/drainage curves and fit predictions from models with observed data. This inversion problem is usually complex and requires global minimization techniques. This paper presents data on bleached kraft hardwood pulps and mixtures with fines and how their surface areas and specific volumes change with composition. These data are further used to predict the behavior of the pulps in drainage situations using models of forming.
Bridging chemical dosage, mixing quality, and variability in paper sheets
Authors: KROCHAK PAUL , CARMINI FASCI GIUSEPPE , NORMAN BO , PRAHL WITTBERG LISA
Published: October 2019

In the first part of this work, a series of paper production trials were performed on a forming experimental (FEX) pilot machine to investigate the distribution of additives in the final product. In these trials, a blue color was dosed into the stock before the headbox instead of a retention aid. Fine paper sheets were produced using twin-wire forming. Visual inspection of the sheets revealed surprisingly high levels of variability of the blue color.In the second part, the effect of different dosage nozzle configurations on downstream mixing quality of a singlecomponent, polyacrylamide retention aid was studied using two-phase computational fluid dynamics. A non-Newtonian model for this phase was implemented using rheological parameters obtained through a combination ofnumerical and experimental analysis. Dosage was made into a turbulent pipe flow under typical industrial approach flow conditions. The effect of the number of dosage points, impingement angle, dosage location, and dosage speed on mixing uniformity was investigated qualitatively and quantitatively.Results from these studies indicate the existence of optimal dosage configurations and point toward strong coupling between chemical addition strategy, mixing quality, and chemical variability in final products.
Analysis of the effects of pressure profile, furnish, and microfibrillated cellulose on the dewatering of papermaking furnishes

Published: October 2019

In this paper, we present an improved experimental method for studying the initial dewatering process in papermaking. We studied the effects of the dewatering pressure profile, the furnish type, and microfibrillated cellulose (MFC) on the development of flow resistance and the final solids content of the filtered sheet. The major difference from the previous studies is the possibility to control the dewatering pressure profile during filtration. The filtration process is monitored by measuring the pressure drop over the filtrated sheet and the flow rate through the filtered sheet as a function of time. In the end, the final solids content is measured. Our results indicate that the sheet solids content after the initial dewatering depends on the magnitude and the shape of the pressure profile used during the filtration and that this dependency remains after wet pressing. Laboratory scale measurements are repeated in pilot scale using a papermaking research environment, with comparable results. Surprisingly, we found that the addition of MFC increases the solids content. This was verified in laboratory and pilot scale studies. Overall, this study shows that laboratory scale measurements can be useful in determining the optimal dewatering conditions for different furnish types.
Combustion behaviors of lignin-lean black liquor and lignin
Authors: ZHAO LIMING , TRAN HONGHI , MAKI KIRSTEN
Published: October 2019

For kraft pulp mills that have thermally limited recovery boilers, lignin removal from black liquor has become an attractive option for increasing pulp production by allowing more black liquor to be processed through the boiler. This study systematically examined the combustion characteristics of lignin-lean black liquor and precipitated lignin from three kraft mills using a thermogravimetric combustor. The results confirm that adding lignin-lean black liquor to its original black liquor decreased the heating value and the degree of swelling of the mixed liquor. The effect on liquor swelling, however, was insignificant for mixed liquors that contained less than 20 wt% of lignin-lean liquor. As with other biofuels, the combustion of precipitated lignin was found to occur through three main stages: drying, volatile burning, and char burning. During the volatile burning stage, hardwood lignin swelled significantly, softwood lignin did not swell much, and mixed hardwood and softwood lignin was somewhere in between. Although the char content in lignin was about half of the volatile content, it took 10 times longer for the char to burn compared to the volatiles.
A three-dimensional model of fine particle retention during percolation through a fiber mat
Authors: BLISS TERRY , OSTOJA-STARZEWSKI MARTIN , CASTRO JAIME
Published: October 2019

Fine particles are usually retained in fiber mats by sieving. To date, no theory has combined fiber and mat characteristics into a predictive retention model. A multilayer analytical retention model developed during this study predicts retention within a thick fiber mat by modeling retention as particles pass through a series of very thin fiber mats. A suspension of 5-75 μm toner particles was percolated through rayon fiber mats. The model’s prediction approached the experimental data only when the ratio of particle diameter to fiber diameter increased toward 2.0, the upper limit within the rayon fiber mat data set. Retention was also experimentally determined on the macroscale with simulated fiber mats, through which 4-20 mm beads were dropped. The particle diameter was at least 2.2 times the fiber diameter for all of the macroscale experimental data, explaining the much better fit of the data from those experiments to the model’s predictions.

Published: October 2019

Purpose. The justification of the reliability and efficiency of the operation of logistics transport systems of mining enterprises taking into account the risks and peculiarities of the operation of hydrotransport systems, which is characterized by instability of the receipt of hydro-mixtures and the use of centrifugal pumps, the working point of the hydrotransportation system on the flow-pressure diagram must be within the range of possible operating modes.
Methodology. An analysis of modern methods for assessing the risks of logistics transport systems functioning in the mining and metallurgical industry with periodic changes in the parameters of the lines and transported materials in order to provide regulated production indicators.
Findings. It has been proved that when moving the main pulp pump station, the risk assessment should be carried out according to two constraints: the inability to provide the cargo flow, which is regulated by the needs of the enrichment industry, and the output of the system's operating point outside the scope of possible operating modes. In both cases, the risk assessment is carried out by comparing the flow rate of the hydrosmixture, which provides the hydrotransport complex after moving the main pulp pump station, with a minimum allowable and maximum allowable flow rate. In the first case, these allowable costs are determined by the rules of the work of the enrichment industry and are within the scope of possible modes of operation, and in the second, it is the abscissa of the boundaries of the region of possible operating modes. It is established that for the majority of enterprises of the mining and metallurgical industry the restrictions on the region of possible modes of operation of the hydrotransport complex will be dominant.
Originality. Based on the analysis of methods for assessing the possible risks of the operation of the logistics transport systems of the enterprises of the mining and metallurgical industry, promising directions of increasing efficiency and ensuring reliability during periodic changes in the parameters of the trunk and material being transported are substantiated.
Practical value.It is concluded in the improvement of the methods for calculating the permissible lengths of logistic transport trunks, which satisfy the requirements of the concentrating production in the traffic flow, with a periodic change in the parameters of the material being transported.

A prospective study was conducted in Sheikh Hasina Medical College,Tangail (250 beded general hospital,tangail) among 75 female patients aged 60 years and above with diagnosed cases of Pelvic Organ Prolapse (POP) during the period from February 2014 to February 2018 who had no desire in coital function. Patient information were recorded pre-operative, per-operative and post-operative period. Urodynamic investigation (uroflometry and post void residual urine) were done during pre-operative  and early postoperative period. Follow up was done at 6 week, 3 month and then annually. Main outcome measures were relieving symptoms, recurrence of prolapse and development of urinary incontinence. Patient satisfaction (Subjective outcome) measured by interview during follow up. Colpocleisis was performed in 75 patients. Mean (age of the patients was 66.69 SD ±5.9 years, mean BMI 18.12 SD ±1.69 kg/m2 and mean parity 5.56 SD ±1.9. Majority of operation done under saddle block, only 21.31% was done under local anaesthesia. Mean operation time was 36.16 SD±6.23 minutes, mean blood loss was 41.61 SD±8.34 ml and mean hospital stay was 2.24 SD ±0.49 days. Objective and subjective outcome were same 98.7% only 1.3% patient developed recurrent prolapse (Failed operation) and 1.3% patient developed urinary urge incontinence. The mean differences were significant for the pre and postoperative maximum urinary flow rate, voided volume, post void residual urine (P value is 0.001). Colpocleisis is safe, effective with high success rate in the management of advance pelvic organ prolapse, who do not wish to preserve coital function. So it can be considered as one of surgical option for treating advance pelvic organ prolapse.

Authors: Kabir Md Humayun , Rahman Munshi Md Mojibur , Khan AKM Musa , Idris Rumman
Published: October 2019

Background: Critical limb ischemia (CLI) is the most severe form of Peripheral Artery Disease (PAD) and represents approximately 1% of the total number of patients with PAD. CLI is associated with a higher risk of limb loss in the absence of revascularization. Objectives of the study are to find out the modality of treatment in CLI, different types of endovascular therapy in CLI and their outcome.

Methods: A retrospective study evaluated 100 patients with CLI reported to cardiovascular surgery department in Combined Military Hospital (CMH), Dhaka between July 2016 to June 2018. Patients with disabling claudication or rest pain and tissue loss are included in the study. All patients were evaluated by peripheral angiogram and revascularisation of limbs was done by endovascular procedure in 79 patients, by surgical intervention in 12 patients.

Results: Forty-four patients (44%) presented with rest pain and disabling claudication, 56 patients (56%) presented with tissue loss. Revascularization of limbs was done in 91 patients (93%). No intervention could be done in 9 patients (9%). Endovascular interventions were done in 79 patients (87%). Twelve patients (13%) underwent surgical bypass. All patients with rest pain remains asymptomatic in 6 months follow up; 2 patients developed reocclusion within 1 year. No major amputation in patients with only rest pain.

Conclusion: Revascularization is the main modality of treatment in CLI. Most of the patient can be treated by endovascular percuteneous procedure. Early intervention in CLI patient without tissue loss carries excellent outcome.

Identifying People with Depression: The role of ‘Self Rated Health’
Authors: Huq Nafisa , Choudhury Tarzia , Aziz Samia , Arafat SM Yasir , Rahman M Omar
Published: October 2019

Depression is the leading cause of disability worldwide. However, it is under recognized and undertreated. Self-rated health is a one-item question that has been used for population health monitoring. It was aimed to examine the prospect of using ‘self-rated health’ (SRH) in identifying people with depression among adult community-based population in Bangladesh over a one-year period controlling for socio-demographic, chronic diseases and symptoms, physical disability, smoking, and life events. We examined data from 3455 participants aged 18 years and above who participated in the 2015 January and 2016 January Health and Socio-Economic Survey of Independent University, Bangladesh. Using multiple logistic regressions, depression at baseline was examined to predict self-rated health at one-year follow-up adjusting for socio-demographic variables, chronic diseases, risk behaviors, and life events. Respondents with depression at baseline had 35% higher odds of reporting poor SRH in the follow-up round compared to those with no depression (OR=1.35, 95% CI=1.03 1.78, P<0.03). SRH may be used by community health workers as a preliminary indicator to identify people who may have depression followed by further screening and management for depression.

Remediación de aguas contaminadas, utilizando dióxido de titanio modificado con hierro como fotocatalizador.
Authors: Ochoa Rodríguez Pablo Alejandro
Published: October 2019

Materiales de dióxido de titanio (TiO2) fueron empleados como catalizadores en la degradación acuosa fotocatalítica del ácido naranja 7 (AO7). Los materiales fueron sintetizados empleando la técnica sol-gel y bajo condiciones hidrotérmicas. Con el objetivo de lograr un uso más eficiente de la luz solar, los materiales fueron modificados con distintas cargas de hierro. Los estudios de caracterización dieron cuenta de la presencia de la fase anatasa en la estructura cristalina interna, de la naturaleza mesoporosa, y del desplazamiento de la absorción hacia mayores longitudes de onda con el agregado de hierro. Las reacciones fueron llevadas a cabo en un reactor batch irradiado desde sus laterales. El catalizador modificado con 0,1% P/P de hierro resultó ser el más activo, elevando el porcentaje de degradación del contaminante hasta 54%, en relación al 26% obtenido con el TiO2 sin modificar. A contenidos superiores de metal, la actividad disminuyó aún por debajo del 26%.
A Qualified Assertion Database for the History of Places
Authors: Plewe Brandon
Published: October 2019

Historical place databases can be an invaluable tool for capturing the rich meaning of past places. However, this richness presents obstacles to success: the daunting need to simultaneously represent complex information such as temporal change, uncertainty, relationships, and thorough sourcing has been an obstacle to historical GIS in the past. The Qualified Assertion Model developed in this paper can represent a variety of historical complexities using a single, simple, flexible data model based on a) documenting assertions of the past world rather than claiming to know the exact truth, and b) qualifying the scope, provenance, quality, and syntactics of those assertions. This model was successfully implemented in a production-strength historical gazetteer of religious congregations, demonstrating its effectiveness and some challenges.
Brain-computer Interfaces and Art: Toward a Theoretical Framework
Authors: Alfano Veronica
Published: October 2019

Art that incorporates brain-computer interface (or BCI) technology sheds fresh light on several aspects of aesthetic theory. Because it is radically interactive and can permit viewers or listeners to modify a work directly by means of their cerebral activity, such art illuminates the role of audience members in shaping that work's meaning; in this way, it literalizes reader-response theory and allows the public to engage even with opaque or alienating pieces. BCI-based art also reframes the significance of the artist's intentions, prompting a reconsideration of the truism that ‘the author is dead’, both by positing a collective form of authorship and by granting a creator access to her own unconscious impulses. Finally, via the notion that it may be possible to transfer unfiltered ideas between brains, BCI-inspired artworks provide a new perspective on art as mediation. Although artists have traditionally been praised for seeming to grant direct access to their emotions, one could argue that artistry happens in the act of concretizing and externalizing one's ideas – that is, in the mediated translation of thought rather than in thought itself. The essay concludes by discussing the implications of this theoretical framework for (among other fields) the digital humanities.
The Church of Scotland and the ‘increase of popery’,c.1690–1714
Authors: Loughlin Clare
Published: October 2019

This article explores representations of ‘popery’ compiled by the Presbyterian Church of Scotland between 1690 and 1714. The ‘increase of popery’ was a ubiquitous phrase in this period. Synods and presbyteries regularly complained of Catholic encroachments in their parishes, and sent extensive reports of the activities of ‘papists’ to the general assembly and its commission. In turn, these national church courts collated these local petitions into longer representations of the ‘state of popery’ in Scotland. Representations have not been examined systematically by scholars. Indeed, representations have often been dismissed as cynical ploys rather than sincere expressions of anxiety at Catholic survival. Yet the very significance of these documents lies in their polemical nature. This article argues that the emphasis on political disaffection in national representations was informed by the Church's fraught relationship with central government, and with rival Protestant groups. Desperate efforts to showcase the necessity of Presbyterian government underpinned national representations of ‘popery’; as such, anti-Catholic sentiments were informed increasingly by the weaknesses of Scottish Presbyterianism as much as by actual Catholic activity. By contextualising representations of ‘popery’ and approaching them as part of a genre, the clerical petition, this article provides new perspectives on the nature of Scottish anti-Catholic polemic.
Nonequilibrium phase transformations in alloys under severe plastic deformation
Authors: Razumov I K , Yermakov A Y , Gornostyrev Yu N , Straumal B B
Published: October 2019

Experimental results and theoretical concepts of anomalous phase transformations in alloys under severe plastic deformation (SPD) are reviewed. The unconventional phase and structural state of alloys that emerges as a result of SPD determines the unique combination of physical and chemical properties that is of interest for various applications in technology. The driving forces and possible mechanisms that implement the anomalous transformations as a function of SPD intensity, alloy composition, and temperature are discussed. We distinguish among these mechanisms two fundamental and qualitatively different ones that are due to: (i) direct ‘mixing’ of atoms in slip bands or (ii) accelerated diffusion on defects under locally alternating thermodynamic conditions and subsequent ‘freezing’ of the nonequilibrium state that is reached. Summarizing the experimental data and theoretical concepts regarding the change in microscopic transformation mechanisms as a function of temperature and/or intensity of treatment, we suggest a diagram of nonequilibrium stationary states attainable during the development of phase and structural instability under SPD. The proposed approach enables the prediction of the structural state of alloys and compounds by controlling thermodynamic and kinetic parameters of the system.

Transversal Alliances: White Fantasies of Indigeneity in Suzanne Desrochers’s Bride of New France
Authors: Karpinski Eva C.
Published: October 2019

Suzanne Desrochers' novel Bride of New France (2011) constructs interesting historical transnationalities linking the French biopolitics of population implemented by Louis XIV, with the story of filles du roi and encounters with indegeneity in colonial New France. Although her narrative explores the possibility of illicit transversal alliances between the oppressed, in this case involving a poor white French woman and an indigenous man, I argue that its potential to reconfigure gendered and racialized spaces of the Empire is thwarted by its generic indebtedness to the genre of the colonial gothic, preoccupied with the "hauntings" of colonialism and imperialism. Moreover, Desrochers' hybrid text, a product of "miscegenation" between history and literature, relies on Eurocentric stereotypes of the Noble Savage and the bad Indian, which suggests that perhaps even her ostensibly feminist attempt to re-read the imperial moment through the stock repertoire of gothic images, no matter how well intentioned, cannot be free from the risk of re-enacting the discursive violence that was constitutive of colonial representation of the Natives and assertions of cultural hegemony. Ultimately, despite its focus on the subjugation of the reproductive female body as a reluctant site of the production of the nation-state, the effect of Bride may well be considered as reterritorializing the nation albeit from a minoritized French perspective.

Antidepressant-Like Effects of Ceftriaxone in Chronic Unpredictable Mild Stress Model in Rats: The Importance of Reuptake Time of Glutamate
Authors: BİNNETOĞLU Damla , ARICIOGLU Feyza , OZCAN Halil , OKKAY Ufuk , HACIMUFTUOGLU Ahmet
Published: October 2019

Objective:
We aimed to indicate the relationship between depression and glutamate, and to
reveal the effect of escitalopram, an antidepressant, which is widely used in depression
treatment and reuptake parameters of glutamate, and to treat depression with
ceftriaxone, one of the beta lactam antibiotics which increased the number and
activity of glutamate transporters.

Methods: In CUMS, rats subjected to series
of different mild stressors in an unpredictable manner for 40 days. On the day 20 rats were
divided in to groups such as CUMS, CUMS+Escitalopram and CUMS+Ceftriaxone. 4 weeks. Treatments were started at 2nd week of CUMS and continued
for 21 days. Anhedonia and antidepressant effect were assessed by sucrose
preference (SP), locomotor activity (LA), elevated plus maze (EPM) and forced
swim test (FST) at the end of the experiment respectively. At the end of the experiment,
behavioral tests were made, and glutamate reuptake time in CA3 (cornuammonis 3)
brain region which are related with depression were measured by means of in
vivo voltammetry technique.

Results: Ceftriaxone
treatment had an antidepressant-like effect. Escitalopram and ceftriaxone increased SP and locomotor
activity, reduced immobility FST, forced swim and time spent in closed arms in
EPM compared to CUMS group. In this in-vivo voltametric study, it was also observed that there was a
significant decrease in glutamate reuptake time in depression.

Conclusion: Escitalopram
and ceftriaxone demonstrated antidepressant-like effects by reversing behavioral changes in CUMS model. Escitalopram
treatment in CA3 region corrected the decrease in glutamate reuptake time which
is consistent with
the hypothesis that enhanced uptake of glutamate might have antidepressant-like
effects.

Five experiments were conducted to examine effects of lysophospholipids (LPL) on live weight gain, nutrient digestibility, ruminal fermentation parameters, serum biochemical parameters and rumen bacterial community profile in fattening lambs. Two dietary treatments (pelleted complete feed supplemented without (control diet; CON) or with 0.05% LPL on dry matter basis) were tested in these experiments. Feed and water were provided ad libitum to lambs. The results showed that average daily gain (ADG) tended to increase or was not affected by LPL supplementation. Compared with CON, the supplementation of LPL resulted in an increase in dry matter, crude protein and organic matter digestibilities, and a decrease in neutral detergent fiber and acid detergent fiber digestibilities. Ruminal pH values did not change with LPL supplementation, but the concentrations of ammonia and total short chain fatty acids (SCFAs) were increased. The molar proportion of major individual SCFAs and the ratio of acetate to propionate were not affected by LPL supplementation. While the activity of lipase was decreased with LPL supplementation, all other serum biochemical parameters did not change. Rumen bacterial community was altered by LPL supplementation with the relative abundance of fibrolytic bacteria in the total bacterial population, such as Prevotella, decreased. In conclusion, LPL supplementation can alter feed digestion, but may not result in consistent positive responses in animal growth performance.
Serum Concentrations of AMH and E2 and Ovarian and Uterine Traits in Gilts
Authors: Steel Alicia , Athorn Rebecca , Grupen Christopher
Published: October 2019

Poor sow retention due to reproductive failure is a common reproductive inefficiency amongst piggeries. This shows that traditional methods of gilt selection are inadequate and a marker of reproductive success is needed. The aim of this study was to determine whether circulating levels of AMH and E2 at D80 and D160 are associated with uterine and ovarian traits at D160. Uterine weight, horn length and horn diameter were measured, and ovarian follicle counts were determined histologically. There was a negative relationship between both D80 and D160 AMH levels and D160 ovarian follicle populations. There was also a positive relationship between D80 E2 levels and uterine capacity in gilts that were pubertal at D160. The findings indicate that D80 and D160 AMH could be used to predict ovarian reserve and that D80 E2 levels may be indicative of uterine capacity in precocial gilts.

Methyl jasmonate (MeJA), common in the plant kingdom, is capable of reducing articular and hepatic inflammation and oxidative stress in adjuvant-induced arthritic rats. This study investigated the actions of orally administered MeJA (75–300 mg/kg) on inflammation, oxidative stress and selected enzyme activities in the brain of Holtzman rats with adjuvant-induced arthritis. MeJA prevented the arthritis-induced increased levels of nitrites, nitrates, lipid peroxides, protein carbonyls and reactive oxygen species (ROS). It also prevented the enhanced activities of myeloperoxidase and xanthine oxidase. Conversely, the diminished catalase and superoxide dismutase activities and glutathione (GSH) levels caused by arthritis were totally or partially prevented. Furthermore, MeJA increased the activity of the mitochondrial isocitrate dehydrogenase, which helps to supply NADPH for the mitochondrial glutathione cycle, possibly contributing to the partial recovery of the GSH/oxidized glutathione (GSSG) ratio. These positive actions on the antioxidant defenses may counterbalance the effects of MeJA as enhancer of ROS production in the mitochondrial respiratory chain. A negative effect of MeJA is the detachment of hexokinase from the mitochondria, which can potentially impair glucose phosphorylation and metabolism. In overall terms, however, it can be concluded that MeJA attenuates to a considerable extent the negative effects caused by arthritis in terms of inflammation and oxidative stress.

To deal with increasingly competitive challenges, today’s companies consider supplier performance as a crucial factor to their competitive advantage. Supplier development is one of the recent approaches to supplier performance enhancement and consistently requires relationship-specific investments. It is important to invest money, experts and/or machines in a supplier to minimize the risk of an inefficient supply chain while maximizing the level of profitability. This paper provides the number of optimization models to confront this issue utilizing Model Predictive Control. We consider a centralized and distributed setting with two manufacturers and one supplier, which enables us to simulate more realistic scenarios. We implement cooperative and non-cooperative scenarios to assess their impact on the manufacturers’ revenue. Results reveal that the cooperative setting between manufacturers pays off better than non-cooperative and collaborative settings in long-term investments. However, for short-term investments, the non-cooperative setting performs better than the others. We can conclude that, in short-term supplier development investments, an added value is generated since both the manufacturers and the supplier gain flexibility, therefore, investing separately can end up with higher profit for both manufacturers.

Published: October 2019

Global warming is now considered to be one of the greatest challenges worldwide. International environmental agreements have been developed in response to climate change since the 1970s. The construction industry is considered one of the main contributors to global warming. In order to mitigate global warming effects, the construction industry has been exploring various approaches to mitigate the impacts of carbon dioxide emissions over the entire life cycle of buildings. The application of different structural systems is considered a means of reducing the carbon dioxide emissions from building construction. The purpose of this research is to assess the environmental performance of three different slab systems during the construction phase. In this study, a process-based life cycle assessment (LCA) method was applied in order to evaluate the level of performance of the three slab systems. The results showed total CO2 emissions of 3,275,712, 3,157,260, and 2,943,695 kg CO2 eq. for the ordinary reinforced concrete slab, flat plate slab, and voided slab systems, respectively. The manufacturing of building materials is by far the main contributor to CO2 emissions, which indicate 3,230,945, 3,117,203, and 2,905,564 kg CO2 eq., respectively. Comparing the building materials in the three slab systems, reinforcing bars and forms were significant building materials to reduce the CO2 emissions in the flat plate slab and voided slab systems. In this study, reinforcing bars were the main contributor to lowering the carbon dioxide emissions in the flat plate slab and voided slab systems. The results of this study show that amongst all the three different slab systems, the voided slab system shows the greatest reduction potential. Moreover, replacing the ordinary reinforced concrete slab system by alternative methods would make it possible to reduce the carbon dioxide emissions in building projects.

This paper aims to manufacture recycled concrete hollow block (RCHB) which can be used for the masonry structure with seismic requirements. Five RCHB masonry walls were tested under cyclic loading to evaluate the effect of the axial compression stress, aspect ratio, and the materials of structural columns on the seismic performance. Based on the test results, the failure pattern, hysteresis curves, lateral drift, ductility, stiffness degradation, and the energy dissipation of the specimens were analyzed in detail. The results showed that with the increase of aspect ratios, the ductility of RCHB masonry walls increased, but the horizontal bearing capacity and energy dissipation of RCHB masonry walls decreased. With the increase of compressive stress, the bearing capacity and energy dissipation performance of RCHB masonry walls were improved, and the stiffness degraded slowly. The results also demonstrated that the RCHB masonry walls with structural columns, depending on whether the structural columns were prepared by ordinary concrete or recycled concrete, could increase the bearing capacity, ductility, and energy dissipation of specimens. The research confirmed that RCHB masonry walls could meet the seismic requirements through thoughtful design. Therefore, this study provided a new cleaner production for the utilization of construction waste resources.

Fine particulate matter (PM) has significant impacts on public health. Among its various chemical components, Polycyclic Aromatic Hydrocarbons (PAHs) are of particular importance since they contribute to a large extent or even enhance its toxic potency. Despite the verified importance of the fine PM pollution for the Greater Athens Area (GAA), information on its composition with respect to the hydrocarbons is extremely scarce. This study aims to uncover the occurrence of the PM2.5 and PM1-bound PAHs across the GAA investigating the impact of the sources and meteorology on the configuration of their profile and potential health risk. The fieldwork took place at three different locations during two different mesoscale wind regimes. Using the Diagnostic PAHs’ Ratio method, the sources were identified while for the quantification of the emissions from the traffic and central heating sectors, the FEI-GREGAA emission inventory was taken into consideration. The potential health risk was estimated calculating the toxic/mutagenic equivalency factors. The peaks for both the PM mass and the PAHs were attributed to the intensity of the emissions. On the other hand, the carcinogenic/mutagenic risk was mainly influenced by the varying characteristics of traffic and especially for the background atmosphere, from the arriving air masses from longer scale distances.

Hybrid capacitors have been developed to bridge the gap between batteries and ultracapacitors. These devices combine a capacitive electrode and a battery-like material to achieve high energy-density high power-density devices with good cycling stability. In the quest of improved electrochemical responses, several hybrid devices have been proposed. However, they are usually limited to bench-scale prototypes that would likely face severe challenges during a scaling up process. The present case study reports the production of a hybrid prototype consisting of commercial activated carbon and nickel-cobalt hydroxide, obtained by chemical co-precipitation, separated by means of polyolefin-based paper. Developed to power a 12 W LED light, these materials were assembled and characterized in a coin-cell configuration and stacked to increase device voltage. All the processes have been adapted and constrained to scalable conditions to ensure reliable production of a pre-commercial device. Important challenges and limitations of this process, from geometrical constraints to increased resistance, are reported alongside their impact and optimization on the final performance, stability, and metrics of the assembled prototype.
