Using Natural and Artificial Microalgal-Bacterial Granular Sludge for Wastewater Effluent Polishing
Authors: Wang Yihang , Sun Penghui , Lin Min , He Qiulai , Ji Bin
Published: July 2023

Marimo is a type of microalgal-bacterial granular sludge (MBGS) that exists in natural water bodies. For the first time, this paper explored the feasibility of marimo in real wastewater effluent polishing, focusing on nutrient removal as compared with MBGS. The results showed that the color of marimo gradually darkened during a 21-day experiment, and the chlorophyll content increased significantly. Although marimo and MBGS showed fairly similar removal performance in terms of NO3−-N and TN, marimo exhibited better phosphate removal as compared to MBGS. Marimo and MBGS contained different algae but the same bacterial phylum of Proteobacteria, including denitrifiers. In addition, marimo had a higher relative abundance of nitrite reductase than MBGS, suggesting that the denitrification process might also happen in addition to assimilation. This study is expected to initiate the application of marimo for wastewater effluent polishing and reclamation, shedding light on nature-based wastewater self-purification technology in the era of carbon neutrality.

A methodology to estimate surface water quality using remote sensing is presented based on Landsat satellite imagery and in situ measurements taken every six months at four separate sampling locations in a tropical reservoir from 2015 to 2019. The remote sensing methodology uses the Box–Cox transformation model to normalize data on three water quality parameters: total organic carbon (TOC), total dissolved solids (TDS), and chlorophyll a (Chl-a). After the Box–Cox transformation, a mathematical model was generated for every parameter using multiple linear regression to correlate normalized data and spectral reflectance from Landsat 8 imagery. Then, significant testing was conducted to discard spectral bands that did not show a statistically significant response (α = 0.05) from the different water quality models. The r2 values achieved for TOC, TDS, and Chl-a water quality models after the band discrimination process were found 0.926, 0.875, and 0.810, respectively, achieving a fair fitting to real water quality data measurements. Finally, a comparison between estimated and measured water quality values not previously used for model development was carried out to validate these models. In this validation process, a good fit of 98% and 93% was obtained for TDS and TOC, respectively, whereas an acceptable fit of 81% was obtained for Chl-a. This study proposes an interesting alternative for ordered and standardized steps applied to generate mathematical models for the estimation of TOC, TDS, and Chl-a based on water quality parameters measured in the field and using satellite images.

Rheumatoid pathology of the articular apparatus is a significant social problem due to the high incidence of disability. Cases of the development of arthropathy after SARS-CoV-2 infection have been described. The basis of the pathogenesis of this condition may be the excessive synthesis of pro-inflammatory cytokines (cytokine storm), which is characteristic of the acute course of COVID-19. In patients with a severe form of the coronavirus infection, a high concentration of a number of cytokines IFN-γ, IL-1, IL-6, IL-12, and TGFβ was observed. Due to the activation of osteoclasts, resorptive processes in bone tissue were significantly enhanced. Autoimmunization due to cross-reactivity of the virus can also lead to joint damage. Reactive arthritis tends to be acute and occurs in the form of monoarthritis or oligoarthritis. The pathological process develops mainly in the joints of the wrist, ankles, and small joints of the distal parts of the limbs.

Authors: Lampila Lucina
Published: July 2023

A simple, rapid test has proven effective for screening seafood for petrochemical taint after an oil spill. This test was widely used after the BP oil spill in the Gulf of Mexico. The test was the screening tool at the point of harvest in order to determine if there was obvious oil contamination of the seafood. The test is sensitive to human detection at a level of over 100 times the level of concern for napthalenes in the BP oil spill. Examples lay personnel and media can relate to their personal experience are effective for explaining scientific analytical test procedures.

Authors: Grotta Amy , McGrath Daniel
Published: July 2023

Extension does not often reach out to undergraduates at their home institutions. Doing so might help Extension reach new audiences; leverage scarce resources; provide meaningful, community-based work experience; and perhaps recruit another generation of Extension professionals. We surveyed students who had completed internships with Extension programs to understand their motivations and to gauge impacts of their internships. Students' understanding of Extension increased exponentially over the course of their internships. They were highly motivated by having a paid work experience that allowed for making professional contacts. Survey feedback will be used to improve, coordinate and expand student opportunities in Extension.

Authors: Brown Tyler , Gering Lawrence , Straka Thomas
Published: July 2023

Global positioning systems (GPS) and Geographic Information Systems (GIS) have become common tools for Extension professionals. These systems vary in terms of accuracy and cost. GPS ranges from recreational-quality to survey-quality, with intermediate levels in between. As the user moves from recreational-quality to survey-quality, both accuracy and cost increase. We compare a recreational GPS unit (Garmin) and importing data into Google Earth software and an intermediate survey-grade GPS unit (Trimble Juno) and importing data into ArcMap GIS software. These represent two of the most common GIS choices available to natural resource professionals. Cost effectiveness will depend on accuracy requirements.

Published: July 2023

The interest and consistency of Malay culture cannot be separated from Islam, this can be seen from the various elements of society who are of Malay blood and even those who are not of Malay blood, always maintaining the preservation of the culture and heritage of the former people. This makes Malay culture an obligation for people who live on Malay land to preserve their ancestral heritage. During this trend, there is a lot of enthusiasm from the community to be able to take part in maintaining this culture. One of them is by producing Malay tanjak and selling it to the public, aiming to make it easier to get Malay tanjak from local business actors. Sustainability later to carry out the practice of making Malay tanjak after the understanding given during the socialization regarding the creative economy and local wisdom based on Malay culture identical to Islam (Malay tanjak) is an excellent potential for those who want to become entrepreneurs in the production of Malay tanjak. Community service targets Tanah Putih 1 Public High School students as an audience and the target of generations who will become successors to preserve Malay culture by buying, producing, and selling it. The hope in this first stage is an understanding of the importance of maintaining cultural preservation and the economic potential of Malay tanjak production in achieving a pioneering business. If the experience has been put together, you can practice making Malay tanjak in activities in the future.

Published: July 2023

The performance of a tunnel furnace and a tunnel dryer in a brick production was exergoenvironmentally assessed. The real production data of a brick factory in Turkey with a daily production capacity of 392 tons of fired bricks were used in the analysis. The exergoenvironmental factor of the control volume was calculated as 0.87. The specific exergoenvironmental cost of the control volume was determined to be 559.55 €/h, 3.39 €cent/ kg fired brick and 1.94 €cent/MJ. The specific exergoeconomic cost and the environmental damage prevention cost were obtained to be 0.41 € cent/MJ and 1.53 € cent/MJ, respectively. Because the ratio of exergoenvironmental cost to sales price of 2.41 € cent / kg fired brick was 1.41 (above 1), it was concluded that the brick production in Turkey was not sustainable in terms of exergoenvironmental analysis.

Authors: OKUBANJO Ayodeji , BASHİR OLUFEMİ Odufuwa , OKANDEJİ Alexander , DANİEL Emmanuel
Published: July 2023

As waste production is becoming more widely recognized as a significant issue, particularly in developing nations, rising food consumption and population growth have caused environmental degradation and health crises. Nigeria's waste collection and disposal problems are commonly associated with environmental pollution and health crises. Consequently, throwing garbage on roads during environmental sanitation, is a typical method of waste disposal, leading to large piles of refuse along the roadside, which hinders the nation's beauty. Therefore, for Nigeria's waste management system to be effective, sustainable smart bins with efficient Internet of Things (IoT) applications must be quickly adopted to create a green, clean atmosphere within cities. Smart bins with integrated IoT can provide a sustainable future for cities' waste management. This model seeks to develop a low-cost, intelligent waste bin system with IoT technology. Sensors and data sharing over a Wi-Fi network, allow for remote control of the waste bin, leading to improved optimization of the bin's level of waste. The economic benefits of this IoT-based system include remote access for efficient level control, lower labour costs, improved time and energy efficiency, and reduced congestion in waste bins.

Authors: BURLAY Tetiana , GRYTSENKO Andrii , BORZENKO Olena
Published: July 2023

Russian-Ukrainian war is the gravest display of the global tension in the hybrid system where war and peace compete as dominant world orders. In view of this, the paper presents the key dimensions of warfare’s societal consequences in the context of the Ukrainian situation. Notably, the ongoing full-scale military conflict has all the characteristics of a hybrid war, unprecedented in its scale in the contemporary history of Europe. In the context of creating a strategic vision of postwar recovery goals and long-term development of the Ukrainian state, the societal consequences of a hybrid war waged against Ukraine must be investigated. The example of Ukraine is used as a backdrop for a detailed assessment of societal consequences of a modern hybrid war in three dimensions – demographic, socio-economic, and macrofinancial aspects. Analysis results indicate the risks inherent in offsetting the societal consequences of the Russian invasion into Ukraine. It is concluded that societal methodology is suitable for exploring the current dynamic transformations in society and its integral structures, and that the application of this methodology should be popularized.

PT. SMI is a manufacturing company located in Surabaya which is engaged in packaging printing using Rotogravure technology where the use of this technology requires a cylinder as the printing material. Before the cylinder manufacturing process is carried out, the cylinder must be numbered first. The workers when doing the numbering often experience complaints in certain body areas such as complaints on the neck, waist, and arms because the cylinder numbering place is considered less ergonomic. This study aims to re-design the cylinder numbering place which is deemed less ergonomic in the hope of reducing the complaints experienced by workers by using an anthropometric approach, namely through data adequacy tests, data diversity tests, determination of BKA and BKB, and calculation of percentiles. Determination of the design dimensions of the numbering table is obtained by doing calculations, namely the eye height in the standing position is 161.1 cm, the elbow-to-hand length is 41 cm, the hand reach is 69.2 cm, and the shoulder-to-elbow length is 69.2 cm. The length of the numbering table itself follows the standard length of the cylinder at PT. SMI is 1400 cm.

Background: India has the highest burden of tuberculosis in world(26%) with an estimated incidence of 26.9 lakh cases
in 2019.Cytomorphology has denitive role in diagnosing tubercular lymphadenopathy however ancillary techniques
like Cartridge-Based Nucleic Acid Amplication Test(CBNAAT) and Ziehl-Neelson(ZN) stain can help in conrmation of the
same.CBNAAT(The GeneXpert polymerase chain reaction test) is capable of diagnosing Tuberculosis within 2 hours.So, it is a promising
tool.The present study was done to assess role of CBNAAT in early diagnosis of Tubercular Lymphadenopathy in addition to cytomorphological
features on Fine Needle Aspiration Cytology (FNAC) and ZN staining. Present st Methods: udy is an observational cross-sectional study of 50
cases of clinically suspected tubercular lymphadenopathy,which were sent to department of pathology for FNAC.After procedure of Flashers
were prepared and stained with routine H&E,Giemsa,Papanicolaou stain and ZN stain.In same setting,aspirate was also sent for
CBNAAT.Results were obtained after detailed study. Out of 50 cases,tuberculosi Results: s was diagnosed in 28 cases based on morphology,ZN
staining or CBNAAT. Overall,21(42%) cases were positive for tuberculosis on morphology,14(28%) cases were positive by ZN stain and
25(50%) cases were CBNAAT positive.Sensitivity of diagnosis of tuberculosis was 89% by CBNAAT alone,75% by FNAC alone,50% by ZN
stain alone and 100% by FNAC and CBNAAT combined. FNAC is the cheapest and si Conclusion: mplest method to diagnose Tuberculosis of

Introduction : Intertrochanteric fractures constitute one of the most common fractures of the hip. These fractures were
initially treated with conservative management, but with recent advancements and techniques internal xation with
Proximal Femoral nail is considered to be the better choice. Stainless steel is a group of Iron based alloys that contains 11% chromium which
prevents iron from rusting and provide heat resistant properties. Titanium alloys contains mixture of titanium and other chemical elements which
have high tensile strength and provide toughness and light weight. This study was done to compare between titanium and stainless steel alloys
made Proximal Femoral nail in the intertrochanteric fractures of femur. This study was done randomi Methodology : zed prospectively in the
Department of Orthopedics ,Trauma center, JA group of hospitals. A total of 60 patients were selected, of which 30 were treated with Titanium
proximal femoral nail and rest 30 with Stainless steel proximal femoral nail. Functional outcomes were measured clinically using rise up and go
rd th rd th test and limb length discrepancy and radiologically union was assessed at 3 week, 6 week, 3 month, 6 month post-operatively. Rise Result :
up and go test and Limb length discrepancy measured in both the cases revealed similar functional outcome in both proximal femoral nails.
Radiological assessment revealed better union rate with Titanium proximal femoral nail. Closed Intertrochanteric fractures treated Conclusion :
