Vehicle Routing Problem (VRP) which is a form of route problem involving vehicles to distribute goods to customers with the aim of minimizing the total distance, minimizing the use of vehicles and the overall distribution time which is expected to reduce errors in selecting gas stations into road routes. Based on the application of the fuel distribution system to gas stations in East Java, especially in the Bojonegoro Regency area using the Vehicle Routing Problem (VRP) method, using a tanker with a capacity of 40 KL is more effective than a tanker with other capacities, distance and operating costs for a tanker of 40 KL the results after the application of the VRP method are more effective than the current distribution patterns, if the VRP method is used it will produce several benefits, including reducing the total mileage of the previous tank car from 3,740 KM to 1,058 KM compared to the current average total mileage of TBBM Semarang-To gas stations in Blora. There was a saving in the cost of diesel fuel from IDR 25,432,000 to IDR. 7,194,400 per day considering there is great efficiency, the pattern for sending Bio Solar fuel from TBBM Tuban to gas stations in Bojonegoro Regency uses a new route using a tanker capacity of 40 tons.
On the Geometry of Speciesist Policing: The Federal Bureau of Investigation’s Animal Cruelty Data
Authors: Beirne Piers , Lynch Michael J.
Published: January 2023

This article contests the animal cruelty statistics newly collected and publicized in the US by the Federal Bureau of Investigation (FBI). In what follows, we (1) outline the inclusion of animal cruelty in the FBI’s National Incident-Based Reporting System (NIBRS), 2016–2020; (2) analyze trends in animal cruelty cases reported in NIBRS; (3) identify key data validity, methodological and theoretical problems in NIBRS, especially with the FBI’s attempt to generate knowledge of the link between animal cruelty and interpersonal violence; and (4) juxtapose the FBI’s circumscribed concept of animal cruelty with the much more inclusive circle of compassion advanced by nonspeciesist and green criminology. We challenge illusions that the criminalization of animal cruelty is driven by a logic of benign inevitability, and ponder how the extension of compassion to a few favored species coexists with and even engenders de-civilizing countertrends, such as the immense abuse that occurs worldwide in the animal industrial complex. Therefore, we issue a call for the development of a nonspeciesist research program, both monocultural and cross-cultural, into the dynamics of the policing and surveillance of animal cruelty and animal abuse in a broad range of societies.

Published: January 2023

Se analizó la distribución espacial de las tasas brutas de mortalidad por cáncer de próstata a escala municipal en la megalópolis mexicana entre 2013-2020 mediante análisis espacial, con técnicas de autocorrelación y regresión espacial. Existe una tendencia creciente en las defunciones, y una distribución heterogénea según los niveles de mortalidad. Se delimitaron las áreas con mayor y menor riesgo. Mediante el Índice Global de Moran se determinó la no aleatoriedad espacial de mortalidad. Con el análisis de clústeres se delimitaron geoestadísticamente aquellas áreas con valores elevados: municipios centrales metropolitanos y algunas zonas surburbanas; y bajos: ciertas zonas periféricas conurbadas. Aplicando el análisis de regresión con retardo espacial se encontró una relación significativa con el envejecimiento demográfico (positiva) y con la presencia de población indígena (negativa), no se halló relación significativa entre mortalidad y acceso a servicios de salud y nivel de pobreza.

Authors: Lakova Iskra
Published: January 2023

This paper presents the biostratigraphic data on the praecalpionellid and calpionellid occurrence in the Ginci and Glozhene Limestone Formations of Middle Tithonian to Berriasian age in the Western Balkanides, West Bulgaria. The stratigraphic raanges, frequency and relative abundance of the praecalpionellid and calpionellid species in two sections have been studied in detail and illustrated. The Chitinoidella, Praetintinnopstella, Crassicollaria, Calpionella and Calpionellopsis Zones and Chitinoidella dobeni, Chitinoidella boneti, Tintinnopsella remanei, Crassicollaria massutiniana, Calpionella alpina, Remaniella, Calpionella elliptica and Calpionellopsis simplex Subzones have been established and described. The Crassicollaria massutiniana Subzone is a new name here proposed as an upper subzone of the Crassicollaria Standard Zone instead of Intermedia Subzone. The praecalpionellid and calpionellid zonation of the W. Balkanides has been correlated to the zonations of different authors in the Mediterranean region. The classical definition of the Jurassic-Cretaceous boundary has been accepted and it has been placed within the Calpionella Standard Zone a little lower than the base of the Remaniella Subzone.

Authors: Sahithya K. , K. Karthika
Published: January 2023

The present study proposed the green synthesis of silver (Ag) nanoparticles using aqueous extract of Acetabularia acetabulum followed by their fabrication onto montmorillonite (MMT). Fourier transform infrared (FTIR) spectra revealed the involvement of multiple functional groups in the reduction of silver ions to Ag nanoparticles and their stabilization on MMT. The obtained MMT-Ag nanocomposites were characterized by UV–visible spectroscopy, powder X-ray diffraction (XRD), particle size analysis (PSA), scanning electron microscopy (SEM) and Energy Dispersive X-Ray (EDX) analysis. The synthesised Ag nanostructures were found to be cubic shaped with average size ranges from 37nm to 60 nm. The seaweed mediated MMT-Ag nanocomposites were evaluated for their potential antimicrobial properties against the isolated biofouling bacteria. Maximum bactericidal activity was recorded against S. aureus followed by E. coli, M. flavus, Pseudomonas aeruginosa, B. cereus, M. leteus and B. subtilis. In addition, the viability of incorporating MMT-Ag nanocomposites in paint was examined where a significant inhibition of marine fouling bacteria was exhibited by the panel coated by MMT-Ag nanocomposites-based paint as compared to water-based paint. The addition of MMT-Ag nanocomposites in water-based paint was also found to be effective against corrosion from marine water. The present study shows cytotoxicity of MMT-Ag nanocomposites as nanoclay/metallic nanocomposites against A. salina with LD50 values of 200±3.4 µg/ml. The results of the present study suggested the application of A. acetabulum extract as a good bio-resource for the synthesis of Ag nanoparticles and their implementation to combat marine biofouling on ship hulls.

Published: January 2023

Celiac disease (CD) is an immune-mediated systemic disorder elicited by gluten which induces an enteropathy with atrophy of intestinal villi. No prevalence information was available for CD in Moroccan children because the diagnosis is based on multiple invasive duodenal biopsies. To simplify CD diagnosis, the objective of this work was to develop an Enzyme-linked Immunosorbent Assay (ELISA) for IgA and IgG tissue transglutaminase (tTG) antibodies detection suitable for Moroccan children. The concentration of the coated antigen and serum dilutions were optimized for the development of IgA anti- tTG and IgG anti-tTG ELISA detection in serum. The cut-off was calculated and the developed ELISAs were used for detecting IgA and IgG-tTG antibodies in 97 serum samples from 97 children aged 1 to 13 years, with variable clinical characteristics. After adjusting optimal working conditions of ELISA, the cut-offs were 0.04 and 0.156 AU for detecting anti-tTG and IgA anti-tTG IgG respectively. The use of IgG anti-tTG as CD marker (100 % of sensitivity) was better than the use of IgA anti-tTG in ELISA tests (90.3% sensitivity). In addition, the ELISA test shows a clear correlation between the IgG tTG antibodies titer and the degree of duodenal damage, estimated by the Marsh stages classification in patients with confirmed CD. Our results suggest that the assessment of the adapted IgG anti-tTG ELISA test can be used for CD in initial screening in Moroccan children after validation with a larger number of samples with CD for confirmation.

Background: Antibacterial agents have always been the part and parcel in the treatment of periodontal infection. One such known agent is Active Leptospermum Honey (ALH) which has been the most studied species of medical grade honey used for the treatment of wounds and burns. Therefore, this study revolves around evaluating the efficacy of active leptospermum honey as a local drug delivery (LDD) agent on probing pocket depth (PPD), relative attachment level (RAL), and periodontal pocket pH. Materials and Methods: Based on the study's inclusion and exclusion criteria, a total of 100 sites with probing pocket depth of ≥ 5mm in posterior region will be selected. The sites will be grouped as: Test Group: 50 sites, Control Group: 50 sites, following the assessment of baseline clinical and biochemical parameters. At the baseline appointment, each patient received full mouth scaling and root planning (SRP). They were called back after 48 hours. Following the assessment of biochemical parameters by using pH test paper strips, MEDIHONEY® was placed as a local drug delivery (LDD) agent in test sites. In control sites only SRP was done. Patients were recalled after 30 days following LDD to reassess only gingival index, plaque index and biochemical parameters. Patients were recalled at 90 days following LDD for the reassessment of all clinical and biochemical parameters. Results: Plaque and gingival inflammation reduced in both groups but test group showed more reduction. Pocket depths were reduced significantly in test site. There was significant pH reduction in test sites. Clinical attachment level was also seen to be improved in the sites which were tested. Conclusion: When administered locally, Active Leptospermum Honey demonstrated lessening of PPD, gingival index (GI), and plaque index (PI), as well as higher levels of clinical attachment (CA).

Hedyotis scandens Roxb. (Family Rubiaceae) is used as a medicinal plant in many communities including Mizoram, northeast India. However, there is little evidence of its therapeutic potential, and scientific proof of its antioxidant capacity is not available to our knowledge and hence, the present study aims to explore the phytoconstituents and curative property of Hedyotis scandens Roxb methanolic leaf extract. Free radical scavenging activity was carried out in vitro. In a concentration-dependent manner, the Hedyotis scandens methanolic leaf extract suppressed the production of ABTS, DPPH and Nitric oxide. The IC50 for DPPH was 35.7±0.14µg/ml, for ABTS it was 50.03±0.12µg/ml and for Nitric oxide the IC50 was 83.61±0.2µg/ml. The presence of compounds such as alkaloid, tannin, flavonoid, and carbohydrate was revealed by phytochemical screening of the plant extract. The total phenolic content was 27.17±0.27 GAE mg/g whereas the total flavonoid content was 29.92±0.3 QE mg/g. The total antioxidant potential of the plant was found to be 98.03±0.14 AE mg/g. Concentration-dependent reducing activity against potassium ferricyanide was seen in the ferric reducing power assay. Antibacterial activity was conducted with two assays and the plant extract showed highest activity against Micrococcus luteus with an inhibition zone of 11.3±0.3mm for 10mg/ml and 15.3±0.3mm for 20mg/ml followed by Escherichia coli at 8.3±0.3mm for 10mg/ml and 10.6±0.3mm, Bacillus subtilis with inhibition zone of 7.3±0.3mm for 10mg/ml and 10.3±0.3mm for 20mg/ml. However, the plant extract did not have any activity against Pseudomonas aeruginosa.

O álcool é uma droga amplamente utilizada, classificada como legal e conhecida por suas características psicotrópicas que promovem a sociabilidade e a integração entre os indivíduos, no entanto, altas concentrações de álcool no sangue causam diminuição da atenção, falsa percepção de velocidade, euforia, aumento do tempo de reação, sonolência, diminuição da visão periférica e alterações neuromotoras, que em níveis variáveis resultam na perda da capacidade de dirigir um veículo e se tornam uma importante causa de morte entre as vítimas de acidentes de trânsito. O presente artigo teve como objetivo realizar uma revisão narrativa aprofundada sobre as causas e consequências da embriaguez e seus efeitos nos crimes de trânsito. Ao serem buscadas maiores bases em especial sob fontes bibliográficas, buscou indícios reais de consentimento no resultado para que se possa caracterizar existente o dolo na conduta do agente embriagado. Também se buscou entender o funcionamento do álcool no organismo. Em análise às definições clínicas de embriaguez, foi possível averiguar a existência de diversos efeitos, níveis de resistência e comportamentos diferenciados, os quais dependem de fatores inerentes ao sujeito. Sendo assim, buscou-se suprimir o objetivo jurídico para as alterações da lei atualmente em vigor, bem como suas alterações realizadas ao longo do tempo. Dessa forma, se observa que a legislação de trânsito brasileira procura tutelar o bem-estar do coletivo ao criar dispositivos que tenha função punitiva e fornecer subsídios pedagógicos em relação aos crimes de trânsito.

Authors: Midura Sara , Fodstad Jill C. , White Benjamin , Turner Angela J. , Menner Scott
Published: January 2023

School-aged youth with behavioral health needs often struggle in the academic environment. When admitted to acute psychiatric hospital settings, the student’s difficulties and needs increase upon discharge and return to the school setting. While the literature describes systemic issues in transitioning from an acute psychiatric hospital to the school setting, limited resources exist for practitioners to plan for and support the successful reintegration of affected students. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the purpose of the current systematic review was to collect and synthesize evidence from the literature (N = 20) in the areas of barriers, challenges, and significance of the need for a formal transition planning framework. Four major key factors emerged as important to assist in creating a transition planning framework for acute psychiatric hospitals to school-based settings: (a) Stakeholder Voice (Student, Caregiver, Hospital/Treatment Team, or School Team Voice); (b) Establishing a Point Person for Transition (Medical or School Point Person); (c) Recommendations/Accommodations (Formal or Informal Supports); and (d) Having a Transition Meeting. Other common factors are discussed, and recommendations are provided to aid practitioners in increasing the likelihood that school-age youth succeed in the school environment post-discharge from acute psychiatric settings. Finally, gaps in the literature are identified as areas for further research.

Authors: Tackett Maria , Viel Shira , Manturuk Kim
Published: January 2023

This study examines Cho & Demmans Epp’s short-form adaptation of Rovai’s well-known Classroom Community Scale (CCS-SF) as a measure of classroom community among introductory undergraduate math and statistics students. A series of statistical analyses were conducted to investigate the validity of the CCS-SF for this new population. Data were collected from 351 students enrolled in 21 online classes, offered for credit in Fall 2020 and Spring 2021 at a private university in the United States. Further confirmatory analysis was conducted with data from 128 undergraduates enrolled in 13 in-person and hybrid classes, offered for credit in Fall 2021 at the same institution. Following Rovai’s original 20-item CCS, the 8-item CCS-SF yields two interpretable factors, connectedness and learning. This study confirms the two-factor structure of the CCS-SF, and concludes that it is a valid measure of classroom community among undergraduate students enrolled in remote, hybrid, and in-person introductory mathematics and statistics courses.
Developmental evaluation of teaching quality: Evidencing practice
Authors: Boyle Fiona , Cook Elizabeth
Published: January 2023

The evaluation of teaching quality and practice is increasingly important in higher education and usually done via student surveys (quantitative data) alone. Much less attention is given to teachers’ self-evaluations of teaching practice (qualitative data). This emphasis on quantitative over qualitative data can result in incomplete and biased measures of teaching quality, and inappropriate changes to educational practice, which may, in turn, negatively impact outcomes, experiences and university micro-cultures. In this paper, we present a case study of an international residential masters module, in rapid transition to online delivery during the COVID-19 pandemic, to demonstrate: 1) how developmental evaluation (DEval) can be used for rigorous critique of teaching practice in conjunction with student satisfaction data; and 2) how qualitative reflections on teaching practice can be transformed into justifiable evaluative evidence, using DEval theory and techniques. Our DEval approach, theorised and enacted using the community of inquiry framework, increased the teachers’ skills and confidence to plan and continually evaluate teaching-learning enhancements. We discuss the implications and benefits of DEval for teachers and universities when used to assess teaching quality. In addition, we expand on existing knowledge to provide clarification on the purposes and appearances of all levels of evaluation in higher education.

Exploring the Impact of Embedded Feminism on U.S. Foreign Policy Towards Afghanistan in the Late 20th and Early 21st Centuries
Authors: Wang Kevin
Published: January 2023

In 2001, the United States invaded Afghanistan to depose its Taliban regime, leading to a protracted military conflict that ultimately resulted in a Taliban victory in 2021. While the invasion was officially in response to the September 11 attacks, this paper seeks to explore whether the theory of embedded feminism may also have played a role in motivating the U.S. to attack the Taliban regime of Afghanistan and to attempt state building in the country. By investigating whether feminist beliefs in the need to save Afghan women from Taliban mistreatment might have led to the U.S. war in Afghanistan, a better understanding of decision-making process in U.S. foreign policy, especially when the important questions of war or peace are concerned, could be obtained. To determine the main arguments used by the U.S. leadership to justify war against the Taliban regime, remarks by influential U.S. politicians and feminist groups as well as resolutions passed by the U.S. Congress and the UN Security Council are analyzed. The conclusion is that the invasion was officially a measure to exercise the right to self-defense after the September 11 attacks, but the embedded feminist principle of using military interventions to uphold the rights of women in other countries, including Afghanistan, in conjunction with accounts of harsh Taliban treatment towards women, were also used to justify and legitimize war at least from the perspective of the Bush administration, with all the implications and reactions from more traditionally pacifist feminist groups that come with such a use of embedded feminist theory in the conduct of foreign policy.

Authors: Yu Shiyang
Published: January 2023

Immersive experience is a new type of interaction that integrates culture and technology, and it shows great promise for application by combining with multi-panel content. With the continuous development of virtual technology, immersive experience is also applied to art exhibitions and obtains surprising effects. People are not satisfied with the original way of art appreciation, and the increase of aesthetic demand also requires more diversified ways of exhibition, which has led to the prevalence of immersive exhibitions.

School bullying does harm to the physical and mental health of bullied students, which cannot be ignored. It not only leads to a significant decline in the academic performance of bullied students and difficulties in academic adaptation, but also reduces their sense of self-worth and easily leads to emotional depression. In this paper, the influence mechanism of campus atmosphere on the phenomenon of school bullying among teenagers is studied, and the research adopts the way of questionnaire survey, taking teenagers as the research object. School bullying questionnaire, Campus Atmosphere Questionnaire and Self-esteem Scale were used to investigate the relationship among adolescents' perception of campus atmosphere, self-esteem and school bullying's behavior. The results show that there is a significant negative correlation between school bullying and the perception of campus atmosphere, that is, the more negative the perception of campus atmosphere, the higher the involvement of students in bullying and bullying others in school bullying. The sampling results based on Bootstrap show that school atmosphere has a negative predictive effect on school bullying of teenagers, and the direct effect is significant, with the intermediary effect accounting for 42.038% of the total effect. The results show that school administrators should create a supportive school atmosphere, so as to improve teenagers' social emotional ability and reduce their possibility of suffering from school bullying.

Annona muricata (soursop) leaves have been traditionally used for medicinal purposes due to its potential antioxidant, anti-inflammatory, anticancer, antimicrobial, and analgesic properties. This study quantitatively determined the phytochemical composition of soursop leaf. Using a BUCK M910 Gas Chromatography with a flame ionization detector, the analysis of phytochemicals was carried out. A 15 m x 250 0.15 RESTEK MXT-1 column was used. Helium 5.0pa.s was used as the carrier gas, flowing at a rate of 40 ml/min, with a splitless injection of 2ul of sample at a linear velocity of 30cm/s. The injector temperature was 280⁰C. At first, operating at 200⁰C, the oven was then increased to 330⁰C at a rate of 3⁰C per minute, and this temperature was maintained for 5min. An operating temperature of 320⁰C was used by the detector. The result shows that soursop ethanolic extract contains phytochemicals that belong to the broad class flavonoids (a class of polyphenolic compounds). They include naringenin (5.92 ug/ml), flavan-3 ol (5.70 mg/l), rutin (2.79 ug/ml), flavanones (3.28 ug/ml), kaempferol (6.15 ug/ml), flavone (1.99 ug/ml), proanthocyanin (2.36 ug/ml). Other polyphenols (not flavonoids) present include resveratrol (7.03 ug/ml), tannin (2.90 ug/ml), catechin (2.49 ug/ml), and epicatechin (7.67 ug/g). The alkaloids found include lunamarin (4.72 ug/ml) and spartein (2.07 ug/ml) while saponins found include sapogernin (16.07 ug/ml) and sapogenin (3.08 ug/ml). Other classes of phytochemicals found include steroids, cyanogenic glycoside, anti-nutrient, and cardiac glycosides. Soursop leaf contains bioactive compounds such as flavonoids, polyphenols, alkaloids, steroids, cyanogenic glycoside and other phytochemicals with medicinal potentials.

In this study, the ripe pericarp extracts of Wodyetia bifurcata were prepared by solvent extraction techniques with and without agitation. The influence of agitation was examined on the extraction yield, total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity of the ripe pericarp extracts of Wodyetia bifurcata. Antioxidant capacity of extracts was evaluated by measuring the scavenging effect on 2, 2’-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 2, 2’-diphenyl-1-picrylhydrazyl (DPPH) radicals. Compared to solvent extraction without agitation, solvent extraction with agitation significantly (p < 0.05) increased the extraction yield, TPC, TFC and antioxidant capacities (ABTS and DPPH) of the ripe pericarp extracts of Wodyetia bifurcata. In addition, higher agitation speed resulted in higher extraction yield, TPC, TFC and antioxidant activities (ABTS and DPPH) of the ripe pericarp extracts of Wodyetia bifurcata.

For many years, dye-sensitized sunlight cells (DSSC), which are feasible and have significant potential to harvest and convert light into renewable energy, have been the subject of serious research. DSSC is a great alternative for low-cost solar panels due to its simplicity in fabrication and acceptable efficiency. While synthetic dyes can produce higher efficiency, their production costs and complexity in synthesizing toxic chemicals that are harmful to the environment, people, and the environment present another problem. Therefore, several studies have focused on natural dyes extracted from plants (chlorophyll-anthocyanin, flavonoid and carotenoid) because of their advantages such as high absorption, low cost, no toxicity, eco-friendly and easy extraction. This review also highlights the development of dye-sensitized sun cells by using natural dyes as photosensitizers.

Much research on the shallot phytochemical is currently employed in various disciplines, such as medical reasons. Shallot (Allium ascalonicum) is a plant species belonging to the family Amaryllidaceae. It is a native plant grown in the North and Northeast region of Thailand. The present study aimed to determine the extracts' yield and antioxidant properties of black shallots made from fresh shallots. The black shallots were extracted with digestion by water, 47.5% and 95% ethanol at 50 ℃ for 1, 3 and 5 hours. The result discovered that black shallot extraction with digestion by water for 5 hours showed the highest weight of extracts (3.620 g). The determination of antioxidant activity by DPPH was observed, and extraction by water for 5 hours gave the highest percentage of inhibition. It was equal to 84.61%, which is not different from the digestion of 95% ethanol for 1 hour, with 83.48%. Similarly, the most outstanding value of IC50 was obtained from extraction with 95% ethanol for 1 and 5 hours with 21.30 mg/ml and 20.52 mg/ml. In terms of monitoring, the digestion method evaluated the productivity of pectin extracts from citrus peel. Hydrochloric acid (0.100, 0.050 and 0.025 M) was used as a solvent at 95 ℃ for 30, 60 and 90 minutes. The pectin extract by 0.1 M hydrochloric acid for 90 minutes gave the highest extract (5.237 g). The preliminary testing of cosmetic production was done by mixing black shallot extracts and pectin from citrus peels, and the two substances can be combined. Still, without adding preservatives, they could cause contamination in cosmetic samples.

The green synthesis of nanoparticles (NPs) from plant extracts is an innovative and considered as an effective method, which has many biological and therapeutic benefits. In this regard, silver nanoparticles were synthesized from leaves of Mangifera indica (Mango) and their properties were characterized. Morphological characterizations such as UV-Visible Spectroscopy (UV-Vis), Fourier-Transform Infra-red Spectroscopy (FTIR), and X-ray diffraction (XRD) confirm the physical characteristics of silver nano-particles. In addition, Mangifera indica phytochemicals possesses DPPH radical scavenging activity, antioxidant, and antibacterial properties. The nano formulation (phytochemicals + NPs) is also tested against the Hep G2 human cell line for anticarcinogenic properties. Nano formulation concentrations at 300μg/ml shown anticarcinogenic effect to Hep G2 human cell lines up to 53.29768%. The Bio pesticidal activity of the paddy pest Cicadella viridis (green leaf hopper) was checked through an antifeedant assay and the activity of the pest was decreased with the introduction of nano formulation. These results show better antioxidant, antibacterial and anticarcinogenic properties. Thus, they can be used to replace chemical therapeutic drugs.

The use of antibiotics has become imperative and unavoidable in medicine to Figureht against microbes, but the majority of these antibiotics are found in environmental ecosystems. It is revealed that the presence of these in the environment, intoxicates the bacterial ecological medium.Then, this investigated the phytoremediation abilities of Water lettuce (Pistia Stratiotes). Adolescent plants were placed in two different concentrations of Ciprofloxacin solution for 7 days. The aim was to see if the plant could remove the Ciprofloxacin, what amount of it and the effects of the drug on the plant thereafter. The concentrations were 50ppm and 10ppm of Ciprofloxacin. The result was that at 50ppm, the plants developed necrosis within 3 days and died. At 10ppm solution, water lettuce managed more than 70% removal efficiency, and also a steady growth of the plant was maintained at 0.1606 g/day. For the concentration of Ciprofloxacin, analysis of sample water was done using UV-Visible Spectroscopy and plant extract was analyzed by HPLC. The study proved that water lettuce can be used as a remediation technique for surface waters, or can be an end-of-pipe measure for pharmaceutical wastewater treatment facilities before discharge into surface waters.
