Publisher Copyright: © 2022, The Author(s).The enormous capability of microalgae for biomass production and co-products has recently been widely researched from a range of research approaches. Microalgae biomass has been discovered as a suitable feedstock for biofuel generation in the third generation. Although they may easily be cultivated in the laboratory, commercial cultivation involves several important considerations, including design, expense, contamination risk, and hygiene. This paper reviews some conventional microalgal cultivation methods along with some harvesting techniques. A short note on the disadvantages of conventional microalgal biofilm cultivation and the need for advanced cultivation techniques are also listed. Further, it highlights some of the modern techniques used for the cultivation of biofilm-based microalgae. It also gives brief information on the various factors affecting the formation of microalgal biofilm. A detailed description of the application of microalgal biofilm concerning biofuel generation is also reviewed. Graphical abstract: [Figure not available: see fulltext.]Peer reviewe

Focus on underserved patients: Improving the collection of PROMs within the HIV outpatient clinic of the Amsterdam UMC
No full textBackground:The HIV outpatient clinic of Amsterdam University Medical Centers (AUMC)is implementing digital patient-reported outcomes measures (PROMS) in routine care to improve the quality of life (QoL) for people living with HIV (PWH). We were asked to design tools to promote the participation of patient groups from Ghana and Nigeria.Methods:Two sets of methodologies were used: qualitative research methods informed the development of a ‘patient journey’ and design-thinking methodologies informed the tool development. Participant observation and in-depth semi-structured interviews were conducted to gain insights into patient- and system-related characteristics. Design-thinking methodologies facilitated the transformation of qualitative data into insights that drove design concepts. Three ideation methodologies were used to create four concepts, leading to the final concept.Results:Observations of 17 individual consultations (6 female, 11 male) at the HIV outpatient clinic resulted in six recurring themes. These themes were: Personal relationship; Disclosure; Impact of the diagnosis; Health literacy & Health involvement; Communication; No-shows. The observations and additional literature research informed the development of an interview guide. Seven interviews (5 female, 2 male) were conducted with participants from Ghana and Nigeria. The observations and interviews informed the patient journey (PJ). The PJ showed that patients experience stress and anxiety prior to and during their hospital visit but fully trust doctors and nurses. Based on the insights the design challenge was addressed, leading to the following concepts: “Peer support community”; “Wellbeing Diary”; “Waiting Room Inspiration”; “Hospital Roadmap”.Conclusions:Amsterdam UMC will adopt the “Wellbeing Diary” which embodies the following characteristics: independence from relying on other organisations or infrastructure for implementation; a visual design that can be used independent of literacy level; and its affordability. The paper diary will provide a low-threshold tool for people to record PROMs-like experiences that will prepare them for their consultations at the outpatient clinic.Design for Interaction | Medisig
Studying the Methods to Determine the Age of Ink: A Critical Review of Ink Dating Methods
No full textOn the basis of the type of ink, pen inks are classified as ballpoint pens or non-ballpoint pens. Ballpoint pen inks are oil-based inks (ballpoint pens). While non-ballpoint pen inks are water-based inks (gel pens, fountain pens, pilot pens, fiber tip pens, etc.). Different approaches related to the determination of the age of ink were proposed in the literature, including ballpoint pen inks, non-ballpoint pen inks and stamp pad inks. This study provides a comprehensive appreciation of analytical research studies that were published from the year 2000 to year 2020 on the determination of the age of inks. Owing To contemporary technological advancements, the process has been developed in many folds. However, its reliability is questioned due to the variability in methods and results. Research works related to the aging of ink have been compiled to assist the researchers and the forensic document examiners and to provide an overall insight regarding the works done so far. In an attempt to unravel this issue of questioned document examination, a critical and systematic review of the literature is proposed to encourage the usage of various tools and techniques necessary to establish the age of ink in different case works

Untreated wastewater is widely used for agriculture in many countries. This is one of the world-leading serious environmental and public health concerns. Instead of using untreated wastewater, treated wastewater has been found more applicable and ecofriendly option. Moreover, environmental toxicity due to solid waste exposures is also one of the leading health concerns. Therefore, intending to combat the problems associated with the use of untreated wastewater, we propose in this review a multidisciplinary approach to handle wastewater as a potential resource for use in agriculture. We propose a model showing the efficient methods for wastewater treatment and the utilization of solid wastes in fertilizers. The study also points out the associated health concern for farmers, who are working in wastewater-irrigated fields along with the harmful effects of untreated wastewater. The consumption of crop irrigated by wastewater has leading health implications also discussed in this review paper. This review further reveals that our current understanding of the wastewater treatment and use in agriculture with addressing advancements in treatment methods has great future possibilities.Peer reviewe

The author would like to thank Deanship of Scientific Research at Majmaah University for supporting this work under project number No. R-2022-68 . Kavindra Kumar Kesari and Janne Ruokolainen thanking Aalto University for providing open access support. The authors would like to acknowledge the support from their respective institutes throughout the review writing process.Purpose: Cervical cancer (CC), one of the major causes of death of women throughout the world is primarily caused due to Human Papilloma Virus (HPV) 16 and 18. The early region (E) oncoproteins of HPV are associated with the etiopathogenesis and contribute to the progression of cancer. The present article comprehensively discussed the structural organization and biological functions of all E proteins of HPV and their contribution to progression of CC with an intent to decipher the pathological hallmarks and their relationship. Additionally, the role of E proteins in reference to therapeutics will also be presented. Methods: A systematic search has been carried out for articles published in PubMed database by using combinations of different keywords with Boolean operators (AND, OR, NOT) including cervical cancer, HPV, E proteins, and signaling. Results: From the analysis of literature review, its apparent that E proteins are the major contributor to disease progression. E1, E2, and E4 forms are mainly associated with viral integration, replication, and transcription whereas E6 and E7 act as an oncoprotein and are associated with the progression of cancer. E5 regulates cell proliferation, apoptosis, and facilitates the activity of E6 and E7. Additionally, E proteins were observed associated with numerous cell signaling pathways including PI3K/AKT, Wnt, Notch and reasonably contribute to the initiation of malignancy, cell proliferation, metastasis, and drug resistance. Knowing the role and interplay of each protein in initiation to progression of CC, their therapeutic significance has been elucidated. The present study observations demonstrate that E6 and E7 are the major cause of HPV-mediated CC progression. E1, E2, and E5 also act as a backbone for E6 and E7 and most of the current approaches have targeted E6 and E7 mediated action only. Conclusion: The present review illustrates the structural organization as well as function and regulation of all early proteins of HPV and their association with several cellular signaling pathways. The observations provide clue on the regulatory aspect of these proteins in initiation to progression and reasonably represent that targeting these proteins could be a novel therapeutic strategy for CC. In particular, its seemingly appears that inhibition of the activity of E6 and E7 oncoproteins may be a better selective target to delay the progression of CC. The review reaffirms the role of E proteins and encourages future studies on developing diagnostics, and most importantly therapeutics strategies targeting E6 and E7 oncoproteins to tackle CC related morbidity and mortality.Peer reviewe
Inadequacies of the Transgender Persons’ (Protection of Rights) Act, 2019: A Juxtaposition with International Legal Frameworks & Conventions
No full textBy way of safeguarding the rights of transgender individuals, the Indian government enacted the Transgender Persons’ (Protection of Rights) Act 2019. Studies show that the Act does not fully comply with many international treaties that aim to safeguard the rights of and provide safeguards for transgender individuals. To commence, to acquire a certificate of identity, transgender individuals are required to undergo a screening procedure administered by a medical officer and a District Magistrate to be certified. This requirement contradicts the idea of self-identification that is highlighted in international treaties such as the Yogyakarta Principles and the Inter-national Covenant on Civil and Political Rights (ICCPR). In this article, the author conducts a comparative study of the provisions that should be promptly added to the Act to give it the necessary prominence that has been overdue
A study of the effect of substrate on dot-matrix printing
No full text A study related to Dot-matrix printers has been carried out in order to analyze the effect of change of substrate on its printing characteristics. Twenty Dot-matrix printers and five types of substrates or white pages have been selected for the study. The printouts have been taken on all the five types of white papers from each of the twenty Dot-matrix printers. These printouts have been examined using stereomicroscope 4x40magnification and VSC 2000 C to examine the features such as change in colour of ink, lustre of printing text, impact of printing, spreading of ink, background noise, UV fluorescence and absorption spectra. It has been concluded that the physical characteristics of dot-matrix printing gets changed by changing the type of substrate even in case of the same printer. Thus, the results of this study would definitely help the forensic document examiners to give an accurate opinion on the cases related to Dot-matrix printouts, specifically in the examination of multiple documents consisting of different types of papers.
