Pore Structure as a Determinant of Flexibility in Sustainable Lime-Cement Mortar Composites
Authors: Olaniyan Sule Adeniyi
Published: November 2021

Flexibility of Lime Mortar resulting from its good permeability feature through its relatively large interconnected pore structure makes it popular as an old sustainable building material. This characteristic feature enhances its capability to suppress masonry deformation. However, its mechanical strength is weak. To address this shortcoming, cement is added to form a stronger composite. This study, therefore, evaluates the pore structure of the resulting lime-cement composite, with a view to assessing impact and sustainability of the lime’s flexibility in the overall performance of the composite. Adopting equal mix ratio (1:3) of Binder/Aggregate (B/A), mortars were prepared using lime as a lone binder, as well as other five different compositions in the ascending and descending order of lime and cement binders (i.e., 1:1, 1:2, 1:3, 2:1 and 3:1). Each composition was assessed in fresh state using Water/Binder ratio, Air Content and Bulk Density. For the hardened state assessments, mechanical characteristics and microstructural features evaluated through six (6) and twelve (12) month curing periods respectively, were considered. Results of the investigation reveal that low cumulative porosity (i.e., summation of the porosities) across the three pore regions of Inter-Nano pores (1 – 10 nm), Super-Nano pores (10 – 100 nm) and Sub-Micro pores (0.1 – 1 µm), for each of the mortars, is observed to be synonymous with low cement content, low Modulus of Elasticity, low (fc/ff), and thus, high flexibility. This observation is supported by high linear coefficient of correlation (R2 = 0.89) for the equation describing both ‘cumulative porosity’ (within the referenced three pore ranges) and cement content. Thus, it could be inferred that despite cement addition with resulting alteration in the pore structure of the composite, presence of lime would retain flexibility property of the composites, with more flexibility in the descending order of cement contents. Considering the impacts of pandemic climate change, growing energy costs and human activities on the environment, this study therefore attempts to promote revival of an old but partially abandoned sustainable lime based mortars, with a view to facilitating improved lime mortar performances, conservation of energy resources and overall protection of the environment.

Authors: Smith A. S. J. , Xu G.
Published: November 2021

Ultra-high performance concrete (UHPC) been an advanced concrete introduced as reactive powder concrete (RPC) over twenty years ago, is now being employed for use in the construction industry of some developed countries like China, Germany and United States of America. Its excellent properties in structural performance and durability make it the civil engineering material that will reshape the future of the construction industry in terms of structural performance; and this paper aims at helping construction experts and developing countries to understand and accept UHPC for use in everyday construction works. The paper gives an in-depth review on the classification of UHPCs based on mix proportion and mechanical properties. Firstly, the mixture design and the mechanical properties of UHPC were discussed. Then UHPC was classified into different types based on mechanical properties and the manufacturer’s modification of the ingredients used for reactive powder concrete or multi-scale cement composite production. This review shows that Funk and Dinger model (also known as Modified Andreasen and Andersen model (MAA)) is the most accepted and widely used mix design method for UHPC. It also revealed that UHPC’s compressive strength, tensile strength and flexural strength are in excess of 150, 7 and 40 MPa respectively. It further classified UHPC into BCV®, BSI®, Cemtec®, Ceracem, Ductal, DURA and UHPC with coarse aggregate; and this classification (especially UHPC with coarse aggregate) is a good sign that local materials can be incorporated into UHPC by developing countries for cost minimisation.

Published: November 2021

This paper studies the stability and ground behavior of the main roadway excavated in a soft rock mass at PT Gerbang Daya Mandiri (GDM) underground coal mine in Indonesia. The stability and ground behavior of the main roadway under various geological and excavation conditions was analyzed and discussed through numerical simulations and field measurement data. Based on the results, it is found that the mechanical conditions of claystone and the geological conditions of the roof have an obvious impact on the stability of the main roadway. The large roof displacement of the roadway occurs when the roadway is excavated in the deteriorated claystone, whereas the small roof displacement occurs when the roadway excavation is made in the undeteriorated claystone and when the coal layer is present in the roof. Under undeteriorated conditions of claystone, the small failure zone and displacement of the roadway occur. The current support system using the steel arch SS400 is effective to control the roadway stability. As the claystone has deteriorated due to groundwater, the failure zone and displacement expand considerably, and the roadway stability decreases significantly. The use of the current support system (steel arch SS400) is difficult to control the stability of the main roadway. Under this situation, a stronger steel arch SS540 is recommended to apply.  Furthermore, the presence of a coal layer during the excavation considerably improves the stability of the main roadway. Compared with the roadway excavated in claystone only, the displacement decreases significantly. In addition, by leaving a thicker coal layer in the roof, a better stability condition of the roadway can be achieved.

Published: November 2021

This article focuses on the role of logistic companies in economic growth and how eco-friendly are implementing eco-friendly technology, green logistics, and considering the United Nations Sustainable Development Goals. This research aims to study the logistic sector in Oman and how its practices could be changed into eco-friendly processes to conserve the environment. The study highlights consumption, which encourages the adoption of green practices. Moreover, the research pays attention to the drivers and barriers to green adoption initiatives. The research used quantitative methods in the form of surveys with the help of qualitative evidence from the literature to reach outcomes. The findings vindicate that Oman places great emphasis on the development of logistics services to achieve economic growth. The implementation of green technology allows companies to help the environment and cost savings. Studies are helpful if managers in the business are willing to bring such practices into their business. There is a need to align sustainable development and logistics operations to support the SDGs in their CSR initiative. The shift usually takes a long time, but the initiative must be taken, and governmental bodies must support the greening of the logistic industry. Research findings reasonably advocate the share of the logistic industry in economic growth, so investments in this sector would only lead to better trade and more earnings whilst conforming to the customers' demands. The study faces some limitations, including a limitation and superficiality in the information presented in the green logistics aspect, the COVID-19 outbreak made it challenging to reach the target people of the survey.
Evaluation and Speciation of Heavy Metals Contamination of Selected Artisanal Mining Sites in Mangu Local Government Area of Plateau State, Nigeria
Authors: Nimyel Nanven D. , Chundusu Elizabeth S.
Published: November 2021

Artisanal (illegal) mining has been reported to have environmental and health effects on the surrounding communities due to heavy metals pollution. The determination of total heavy metal concentration does not reflect the toxicity and bioavailability of the metals. Toxicity and bioavailability of the metals can be achieved by determining the form in which the metal exist in the environment (speciation). This present work evaluated the heavy metals’ {cadmium (Cd), copper (Cu), manganese (Mn), lead (Pb), zinc (Zn) &nickel (Ni)} contamination and the form in which they exist at some mining sites in Mangu LGC, Plateau state, Nigeria. Aqua regia ((HCl + HNO3, 3:1 v/v) was used for total metal concentration while sequential extraction method was used to orderly determine the speciation of the heavy metals. The level of the heavy metals in the digested solutions were determined using Buck Scientific model 210VGP Atomic Absorption Spectrophotometer (AAS). The results divulged that the concentrations of the heavy metals were within the FEPA and WHO recommended permissible limit except Cd and Ni. The values of the metals at Mangu Halle mining site followed the sequence: Mn > Zn > Ni > Pb > Cu > Cd whereas the sequence at Alogwom was Mn > Zn > Pb > Ni > Cu > Cd. The results of the speciation indicated that all metals were bound to the five fractions with the residual fraction dominating except Cd which was bound mostly to the soluble and exchangeable fractions. It could be concluded that the presence of these heavy metals in the mobile fractions, indicate that they could be easily released to the environment from soil. Thus, they are also likely to cause toxicity in the environment. Proper monitoring of the mining activities in the communities was recommended.

PAPR Reduction in OFDM Systems Using Hybrid Zadoff-Chu Transform Precoding and Partial Transmit Sequence
Authors: Oyegoke M. A. , Olasoji Y. O.
Published: November 2021

Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation (MCM) scheme that plays a significant role in digital wireless communication. As a result of its high data rate capability and immunity to multipath fading effect, among others, OFDM remains an ideal technology for 5G communication systems and beyond. Unfortunately, a major drawback of this technology is the high peak-to-average power ratio (PAPR). Nevertheless, many techniques for reducing PAPR have been proposed in the past to address this problem. However, all the techniques previously used have limitations such as high computational complexity, data rate loss, high signal distortion, increase in bandwidth, increase in transmit power, and memory requirements. In this paper, a hybrid technique that combines Zadoff-Chu Transform (ZCT) precoding and Partial Transmit Sequence (PTS) for reducing high PAPR in OFDM signals is presented. To reduce the data rate loss and computational complexity in PTS when a large subblock is used, a Zadoff-Chu precoding is applied to OFDM symbols to precode the symbol before applying PTS with a fewer number of subblocks. An OFDM model was developed where ZCT and PTS techniques were implemented. The performance of the hybrid model was analyzed using Power Spectral Density (PSD), Complementary Cumulative Distribution Function (CCDF), and Bit Error Rate (BER). The simulation result indicates that the hybrid ZCT-PTS provides a better result than using either Zadoff-Chu precoding technique or Partial Transmit Sequence technique separately. A PAPR of 4.2 dB and BER of 3dB is achieved for hybrid ZCT-PTS. The hybrid technique provides a better system performance when compared with Conventional OFDM systems.

Published: November 2021

He Waka Hiringa (HWH) is a Masters of Applied Indigenous Knowledge offered as a programme of two years’ study by Te Wānanga o Aotearoa. The main pre-requisite for enrolment in to this graduate degree is for the student to be a master of their own practice, whatever that practice may be. In other words, they are already leaders in their own field of practice. My task is to help them clarify how they indigenise their practice; introduce them to academic processes to achieve the rangahau (research) around this and encourage them to create their own Models of Practice (MsOP) to guide them as they work with students or clients.

In six years three cohorts of students have succesfully graduated through my encouragement in the development and approval of about 100 different new MsOP, each unique in its own way. These add to the use by graduates of HWH to models such as Whare Tapatoru ( Wi Te Tau Huata Snr. 1967, personal communication), Whare Tapawhā (Durie, M. 1984), Te Wheke (Pere, R. 1997) and Poutama Pōwhiri (Huata, P. 2011) to name a few well known MsOP.

In terms of a Leadership MOP I have not seen a better model than that created by Te Wairere Te Pūāwaitanga o te Whakaaro Ngaia (my youngest child and daughter) to fulfil the requirements of her Masters in Management Communications and Te Reo Māori (Māori Language) graduate degree at The University of Waikato. I am going to use her MOP for leadership in competitive Kapa Haka[1] (Māori performing arts) as my model in this delivery with her permission. The title comes from a waiata-ā-ringa (action song) composed by one of her tuākana (older sisters), Te Ingo Karangaroa Ngaia, entitled ‘He Rākau Taumatua!’[2], for their whānau (family) kapa haka, Te Haona Kaha.

Authors: Niemiec Brook A. , Gawor Jerzy , Tang Shuiquan , Prem Aishani , Krumbeck Janina A.
Published: November 2021

OBJECTIVE

To compare the bacteriome of the oral cavity in healthy dogs and dogs with various stages of periodontal disease.

ANIMALS

Dogs without periodontal disease (n = 12) or with mild (10), moderate (19), or severe (10) periodontal disease.

PROCEDURES

The maxillary arcade of each dog was sampled with a sterile swab, and swabs were submitted for next-generation DNA sequencing targeting the V1–V3 region of the 16S rRNA gene.

RESULTS

714 bacterial species from 177 families were identified. The 3 most frequently found bacterial species were Actinomyces sp (48/51 samples), Porphyromonas cangingivalis (47/51 samples), and a Campylobacter sp (48/51 samples). The most abundant species were P cangingivalis, Porphyromonas gulae, and an undefined Porphyromonas sp. Porphyromonas cangingivalis and Campylobacter sp were part of the core microbiome shared among the 4 groups, and P gulae, which was significantly enriched in dogs with severe periodontal disease, was part of the core microbiome shared between all groups except dogs without periodontal disease. Christensenellaceae sp, Bacteroidales sp, Family XIII sp, Methanobrevibacter oralis, Peptostreptococcus canis, and Tannerella sp formed a unique core microbiome in dogs with severe periodontal disease.

CONCLUSIONS AND CLINICAL RELEVANCE

Results highlighted that in dogs, potential pathogens can be common members of the oral cavity bacteriome in the absence of disease, and changes in the relative abundance of certain members of the bacteriome can be associated with severity of periodontal disease. Future studies may aim to determine whether these changes are the cause or result of periodontal disease or the host immune response.
Volume of saline (0.9% NaCl) solution required to reach maximum peristaltic pressure in cadaveric intact jejunal specimens from dogs of various sizes
Authors: Culbertson Tricia F. , Smeak Daniel D. , Rao Sangeeta
Published: November 2021

OBJECTIVE

To compare the volume of saline (0.9% NaCl) solution required to reach a maximum intraluminal peristaltic pressure of 25 mm Hg in dogs of various sizes.

SAMPLES

25 grossly normal jejunal segments from 6 canine cadavers < 20 kg (small dogs) and 25 segments from 5 cadavers ≥ 20 kg (large dogs).

PROCEDURES

Jejunal specimens were obtained within 1.5 hours after euthanasia. Harvested tissue was transected into 12-cm-long segments, mesentery was trimmed, and each segment was measured from the antimesenteric to mesenteric serosal edges. A 10-cm segment was isolated with Doyen forceps, securing a pressure sleeve within the lumen. Intraluminal saline was infused, and the volume was recorded when a pressure of > 25 mm Hg was achieved. Data were analyzed only from specimens in which the pressure remained between 24 and 26 mm Hg for > 5 seconds.

RESULTS

Mean ± SD intestinal measurement for large dogs (17.82 ± 1.44 mm) was greater than that for small dogs (12.38 ± 1.38 mm) as was the volume of saline solution infused (17.56 ± 7.17 mL vs 3.28 ± 1.41 mL, respectively). The volume infused increased by 1.31 mL (95% CI, 1.08 to 1.18) for every 1-mm increase in intestinal measurement and by 1.06 mL (95% CI, 1.052 to 1.068) for every 1-kg increase in body weight.

CONCLUSIONS AND CLINICAL RELEVANCE

The volume of saline solution used for intestinal leak testing should be determined on the basis of patient intestinal measurement or body weight. In vivo studies are necessary to establish the optimal volume for intestinal leak testing.
Simulation of the effect of low-cost companion animal clinics on the market for veterinary services
Authors: Haston Roger B. , Pailler Sharon
Published: November 2021

OBJECTIVE

To understand the market dynamics of companion animal veterinary services through the simulation of willingness to pay and willingness to wait as consumer behavior attributes.

SAMPLES

Numerical distributions for the willingness to pay and willingness to wait of simulated potential clients of companion animal clinics.

PROCEDURES

Simulations were run by use of numerical distributions to create demand curves and analyze market dynamics across 2 market segments (price sensitive and price insensitive) and different price dispersion between clinics.

RESULTS

The simulations suggested that the profit-maximizing price of a full-service clinic created a natural segmentation of the companion animal veterinary market, with a majority of clients coming from the price-insensitive segment. The simulation of 2 clinics (full-service and low-cost) with 2 market segments showed an increase in the overall market for veterinary services when a low-cost clinic was present. In addition, the lower the price charged at the low-cost clinic, the greater the profits for the full-service clinic.

CONCLUSIONS AND CLINICAL RELEVANCE

The presence of multiple prices for the same services, or price dispersion, in a market increases the overall market value and services more clients. Discouraging low-cost companion animal practices from entering the market decreases efficiency by leaving a population of pet owners unserved and ultimately reduces the overall market for veterinary services and the economic viability of veterinary practices.

Published: November 2021

OBJECTIVE. We investigated the relationship between Lund-Mackay scale, olfactory bulb depth and width, and Keros classification in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).

MATERIAL AND METHODS. In this retrospective study, paranasal sinus computed tomography (PNSCT) images of 47 patients with CRSwNP and 47 healthy subjects (control) were evaluated. In the CRSwNP group, PNSCT scans were assessed based on Lund-Mackay scale. In both groups, olfactory fossae (OF) depth and width, and Keros classification were evaluated.

RESULTS. The total Lund-Mackay score was 17.1±5.9. There were no significant differences between OF depth and width values of the nasal polyps group and control group. For both groups, Type II Keros was the most detected type; secondly, Keros type I and rarely Keros type III were detected. There was no significant correlation between Lund-Mackay score (All items and total score) and OF depth and width, and Keros type. There were negative correlations between ipsilateral OF depth and width (p<0.05), whereas there were positive correlations between contralateral OF depth and width (p>0.05). Keros type was positively correlated between ipsilateral and contralateral OF depth and Keros type (p<0.05). In older patients, left OF depth and Keros type decreased (p<0.05).

CONCLUSION. As a conclusion, there was no correlation between Lund-Mackay score and olfactory fossa dimensions (depth and width). When considering age, one could notice that Keros type decreased in older patients.

The paper considers the development of mathematical models of combined heat and power plants that are to be used while modelling the fuel and energy complex. Consideration is given to three methods of combined heat and power plant (CHP) modelling: The first method provides for the simplified modelling based on CHP aggregation in one energy zone; the second method is based on modelling the individual CHP using the accurate parameters of their equipment operation; the third method is based on the use of standard regime diagrams for modelling individual CHP. Analysis of the presented methods of CHP modelling revealed that the third method out of the three methods proposed is most appropriate for mathematical models of fuel and energy complex for studying the fuel and power supply reliability. The experimental part of the paper describes the process of deriving the analytical dependencies of electricity and heat generation versus fuel used by CHP that is obtained by the third method proposed.

We studied the reproductive traits in 23 of 190 individuals of Capoeta umbla caught monthly in the Solhan Creek of the Murat River between April 2017 and March 2018. The sex ratio (F:M) was found to be 1:1.11. The macroscopic examination of the gonads and gonado-somatic index indicated that the reproductive period lasted from May to August with peak activity in May. The fecundity ranged from 2,000 to 9,000 oocytes, and it correlated with the total length and body weight. This work represents the first attempt to investigate the reproductive traits of the Capoeta umbla population in the Solhan Creek. The results provide information on the reproductive biology and contribute to the conservation of the fish population and its sustainable management.

Authors: Kammarchedu Bhushanam Jeevan Prasad , Aluri Jacob Solomon Raju
Published: November 2021

212 marine fishery resources were recorded in the waters of Andhra Pradesh State. Morphometric data was provided for 20 edible fishery resources landing at the fishing harbour of Visakhapatnam. The harbour area is polluted due to influx of various industrial effluents and domestic sewage. In Pampus argenteus, P. chinensis and Parastromateus niger, the total protein content is 16.24-19.58%. Further, arsenic concentration in muscle and gill portions individually or combined in all three of the species is highly negligible. Cadmium, mercury, and lead levels in the muscle and gills of these species are within or slightly above the recommended limits set by EU (2006) and FAO (2003), FAO/WHO (2011), MAFF, and FSSAI (2011) indicating that the consumption of these fishes is not harmful.

Published: November 2021

Consumer orientation towards Green Products or environmentally friendly products is one of the supporting factors for business continuity (business sustainability). Consumer behavior in choosing a product is primarily determined by several things such as available product design, consumer knowledge, government control over consumers and producers. The role of the Government, Consumers and Producers together forms consumers' character in selecting the products to be consumed; therefore, the part of these three elements becomes essential to study. This study focuses on the role of government control, considering that other variables, namely consumers and producers, have been widely discussed in previous research studies. This study involved 210 respondents who live in Jakarta and surrounding areas. The selection of respondents was carried out by purposive sampling method with the criteria of respondents being groups of people who buy products for their own needs (not for resale). Data analysis was performed using Structure Equation Modeling - Partial Least Square (SEM-PLS).
