Status and challenges of wood biomass as the principal energy in Sierra Leone
Authors: Fayiah Moses , Dong Shikui , Singh Sanjay
Published: March 2024

Energy availability in developing countries especially in African countries is still a great challenge, affecting the standard of living and investment in the Continent. The absence of adequate energy supply in urban and rural areas in Africa since colonial era has given wood biomass energy the advantage among other energy sources. In this paper, we synthesized the literatures and reports to assess the wood biomass energy usage status, production, consumption, economic benefits, pitfalls and future trend in Sierra Leone. The combined energy supply from all sources in Sierra Leone accounts for less than 30% of the country energy needs. The huge reliance on wood biomass energy in Sierra Leone is as a result of poverty, high cost of alternative energy source, weak economy and under development of the state, corruption, previous civil war, political instability and low standard of living. The exploitation of other forms of renewable energy such as modern bioenergy, solar, wind, and increased hydroelectric production could increase energy access and diversify Sierra Leone’s energy profi­le in the near future.

Authors: Lim Jun Wei , Khoo Kuan-Shiong , Lam Houy-Yng , Lau Zhen-Yin , Ching Wuie Alyna Ong , Azlan Anissa , Beh Hoe-Guan
Published: March 2024

This study compared the effectiveness of powdered activated carbon (PAC) to adsorb 4-chlorophenol (4-CP) from wastewater via coated onto and homogenised into polyvinyl alcohol (PVA) bead surface. The bioregeneration of spent PAC for repeated uses via entrapment with 4-CP acclimated biomass of activated sludge was also unveiled. Results showed that the maximum capacity of PAC adsorbing 4-CP was 0.2 g 4-CP/g PAC. It was confirmed that the PAC coated onto bead surfaces with biomass entrapment could be used for 8 cycles with removal efficiency ranging from 80-85%. The removal rate of 4-CP was best fitted by the pseudo-first-order reaction kinetic, permitting plausibly projection to upscale for industrial application in treating wastewater containing chlorophenol more effectively.

An environmental impact assessment of the management of cassava waste: a case study in Thailand
Authors: Vahdati Maria M , Prakobboon Natikorn , Shahrestani Mehdi
Published: March 2024

In Thailand, cassava waste is one of the main biomass residues and has the potential to be used as a biomass fuel. However, currently most cassava waste in Thailand is left in agricultural fields or burnt on site and is not utilised for any energy-related purposes.

This research investigates the environmental impacts associated with three cassava waste management practices including (i)- ploughing the waste to the soil (ii)-burning the waste in the field (iii)- collecting and using the waste in cassava-based bioethanol plant. The environmental impact assessment and material flow analysis associated with these management practices were conducted using the Global Emissions Model for Integrated Systems (GEMIS) package [1]. The outcomes of this study reveal that the CO2 emissions associated with these waste management practices are about 0.195, 0.243 and 0.361 kg CO2-eq/kg of as received (wet) cassava waste, respectively. Compared to other cassava waste disposal methods such as ploughing and burning, cassava waste collection would result in the biggest environmental impact, emitting nearly 85% more GHGs than ploughing and 48% more than burning.

A Comparative Study On The Heat Release During The Combustion Of Coal And Oil Palm Biomass Charcoal Briquette Via Thermogravimetric Analysis (TGA)
Authors: Aliyu Aminu Safana , N Abdullah , Zangina Tasiu
Published: March 2024

The world is seriously searching for an alternative to fossil fuels due to their tremendous environmental effect. However, renewable energy sources such as solar, wind, hydropower, and biomass were anticipated to be alternative energies. In this study, the amount of heat generated from the combustion of coal and charcoal briquettes derived from oil palm biomass was investigated and compared. Charcoal briquettes were made from the biochar obtained after the pyrolysis of empty fruit bunches (EFB) and mesocarp fibre (MF). Coal and charcoal briquettes were subjected to combustion via thermogravimetric analysis (TGA) at a 10oC min-1 heating rate to a maximum temperature of 850oC. The ignition and burnout temperatures were 235oC and 675oC for EFB, 254oC and 788oC for MF, and 368oC and 770oC for coal. The maximum heat released 0.06 W was obtained from EFB charcoal briquette followed by 0.05 W and 0.04 W from coal and MF charcoal briquette, respectively. This finding indicated that charcoal briquettes derived from oil palm biomass (EFB) could be one of the potential solid fuels that can be used for coal replacement.

Authors: Mohd Nadzim Ummi Kalsum Hasanah , Yunus Robiah , Omar Rozita , Lim Bo Yuan
Published: March 2024

One of the key performance indicators of the palm oil mill is the oil extraction rate (OER), indicating the amount of oil that can be extracted from the fresh fruit bunches (FFB). The OER currently fluctuates throughout the years. Thus, this paper reviews the technical factors contributing to the fluctuation of OER in terms of oil losses in the crude palm oil (CPO) production process in Malaysia. The sources of oil losses could be attributed to oil palm planting materials, loose fruits, ripe bunches and unstripped bunches (USB) andprevention actions have been reported by several researchers. High oil losses also occur at the waste streams during processing, such as steriliser condensate, pressed mesocarp fibre and sludge from clarification process.Moreover, oil losses have a significant impact on CPO revenue. The future outlook of Malaysian CPO is promising for CPO export, import and revenue in the year 2020 due to the implementation of biodiesel (B7, B10 and B20) in the industrial and transport sectors. All relevant parties in the palm oil industry should understand the factors contributing to oil losses for necessary actions taken to improve OER and reduce oil losses as well as achieve a sustainable palm oil industry.

Authors: Janaun Jidon , Carrie Ong , Anisuzzaman S.M , Krishnaiah Duduku
Published: March 2024

In this paper, a renewable carbon catalyst was developed based on the non-functionalisation method. Three different pyrolysis temperatures at 400°C (SC400), 500°C (SC500) and 600°C (SC600) were used to prepare amorphous carbon. The non-covalent functionalisation was carried out by 1-pyrenesulfonic acid (1-PSA) in organic solvents such as ethanol, heptane and dimethylformamide (DMF), and characterised by total acidity, TGA, FT-IR, SEM-EDX, particle size, BET Porosity, and XRD. The total acidity was found to be 1.58 mmol/g for catalyst SC400. The functional groups –COOH, –OH, –SO3H and π-π stacking were detected. The amorphous carbon was stable until 500°C. The sulphur content was found to be 0.013mmol/g for SC400. This research approach focused on the direct interaction of carbonaceous support with pyrene moieties and terminal groups (–SO3H) acting as catalytic acid sites that open a new way to be explored for performing liquid-phase heterogeneous acid-catalysed reactions.Keywords: Non-covalent functionalization, Amorphous carbon, sulfonation, surface morphology, D-Glucose carbon
Applying Software Engineering Based on Peer to Peer ‎‎Communication
Authors: Salim Asma
Published: March 2024

The JavaScript programming language was selected to create software creation that facilitates the creation of a video connection between users because it enables the creation of cross-platform apps relatively quickly. For example, “Web Real-Time Communication (WebRTC)” standards do not specify exactly how two browsers initiate and manage communication with one another. The reason for this is that WebRTC does not specify the signaling technique or protocol. This paper's main goal is to design and construct a WebRTC simultaneous video conference between peers utilizing Google Chrome and the Socket.io signaling technology. A Local Area Network was used in this experiment (LAN). Furthermore, an assessment was conducted on the quality of experience (QoE), the Socket.io signaling method, and resources, including bandwidth consumption. This paper describes the simultaneous execution of peer-to-peer video calls with user identification (user-id).

Shock index for prehospital sepsis recognition
Authors: Banerjee Anjali , Barbera Andrew , Melton James , Banerjee Paul
Published: March 2024

Objective

The authors of this study aimed to assess the effectiveness of prehospital shock index (SI) and modified shock index (MSI) as predictors for sepsis and related outcomes. They aimed to determine whether the SI and MSI correlated with hyperlactatemia, which is considered a marker of sepsis severity and a predictor of poor prognosis.

Methods

This was a prospective cohort study including all adult patients transported by our county EMS system as per our system’s prehospital sepsis protocol. The study was approved by our medical school’s institutional review board.

Results

The study cohort included 1,426 patients. Of these, 969 had an elevated SI. The initial SI ranged from 0.260 to 2.840, with a median of 1.11, and 68% had a “positive” SI (>1.0). The initial MSI ranged from 0.336 to 3.727, with a median of 1.465, and 74% of the cohort had a “positive” MSI (<0.7, or >1.3). Of the patients, 92% had repeat vitals during transport, and the second SI was elevated in 41%. The study found that patients with an elevated SI were significantly more likely to have an elevated lactate (P=0.0309) and be admitted for sepsis (P<0.0001, 95% CI 0.1038 to 0.2714). Patients with an elevated serum lactate were significantly more likely to die during their hospital stay (P<0.0001, 95% CI 0.1503 to 0.3210) with an odds ratio of 2.38 (95% CI 1.59 to 3.56).

Conclusion

The study data suggest that an elevated shock index >1 can be used as a surrogate marker for elevated lactate, which in turn correlates with sepsis and poor outcomes following sepsis.

Published: March 2024

The global manufacturing sector is confronted with mounting challenges related to safety hazards and environmental sustainability. In response, there has been a growing emphasis on adopting circular economy principles as a transformative approach to address these pressing issues. This review explores the implementation of circular economy principles within manufacturing processes to enhance safety and environmental sustainability. Circular economy principles prioritize resource efficiency, waste reduction, and the continual use of materials within closed loops. By shifting from the traditional linear "take-make-dispose" model to a circular approach, manufacturing facilities can significantly mitigate safety risks associated with hazardous waste generation and disposal. Moreover, the adoption of circularity fosters a culture of preventive measures, reducing the likelihood of workplace accidents and improving overall safety standards. Furthermore, integrating circular economy principles into manufacturing operations contributes to environmental sustainability by minimizing resource depletion and pollution. Through strategies such as product redesign for recyclability, remanufacturing, and waste valorization, manufacturers can reduce their reliance on virgin materials and curb emissions. This transition towards circularity not only diminishes the environmental footprint of manufacturing activities but also creates opportunities for cost savings and innovation. However, the successful implementation of circular economy principles in manufacturing requires a concerted effort from stakeholders across the value chain. Collaboration among manufacturers, suppliers, policymakers, and consumers is essential to overcome barriers such as technological limitations, regulatory constraints, and behavioral change resistance. Embracing circular economy principles holds immense potential for enhancing safety and environmental sustainability in manufacturing. Through systematic integration and collaboration, the manufacturing sector can pave the way towards a safer, more sustainable future.
Fundamentos Schelerianos Da Logoterapia
Authors: Cadena Nathalie Barbosa de La , Castañon Gustavo Arja
Published: March 2024

A Logoterapia proposta por Viktor Frankl está fundamentada na teoria dos valores e antropologia de Max Scheler. Frankl constrói seu pensamento psicológico baseado em conceitos-chave do pensamento scheleriano como (i) o valor e os bens, (ii) o querer e os sentimentos, (iii) a hierarquia de valores e (iv) a ideia de pessoa. É com eles que desenvolve suas teses originais da (i) motivação espiritual da ação humana, (ii) busca de sentido e (iii) inconsciente espiritual. Ao fazê-lo, ofereceu não só uma psicoterapia dos valores, mas também uma nova teoria da motivação humana positiva, não concebida como fruto de deficiência ou necessidade, mas do espírito livre direcionado a valores objetivos. A busca humana por sentido na vida só é possível ser bem-sucedida com a vivência e realização de valores superiores, no sentido hierárquico proposto por Scheler.
Gerenciamento Do Tempo Na Era Da Técnica: Reflexões À Luz Do Pensamento Heideggeriano

Published: March 2024

Este artigo tem como propósito aprofundar a discussão acerca do fenômeno designado como “gerenciamento do tempo”, a partir das ideias heideggerianas que circundam a expressão cunhada por ele de “Era da Técnica”. Destaca-se; em particular, as reflexões do filósofo sobre o pensamento calculador (operacional, pragmático e apartado da reflexão do que é mais próprio e originário da experiência de ser-no-mundo), o sentido da ocupação e as disposições afetivas angústia e tédio. Busca-se compreender a relação entre o modo de vida atual, caracteristicamente acelerado e superficializado, a reificação de uma apregoada necessidade e pretensa habilidade de “gerir o tempo” e o esquecimento da vivência da temporalidade como fluxo existencial. Pretende-se, simultaneamente, refletir criticamente, sobre as mudanças, implicações e impactos advindos das novas configurações sociais produzidas por este modo de pensar, cujos alicerces parecem assentar-se na concepção moderna de tempo enquanto medida e produto.
Sobre O Problema Da Experiência Ontológica

Published: March 2024

A filosofia atualmente vigente na Alemanha encontra-se na urgência de uma reviravolta. Isso não diz respeito a uma aporia ou a um constrangimento do espírito humano, dos quais finalmente novas e radicais questões pudessem ser despertadas, assim como uma revolução no modo de pensar. Nesse sentido, todo pensar autêntico já se encontra desde sempre e por toda parte em uma tal urgência. Isso tampouco diz respeito à tragédia histórico-espiritual da Europa, à entonação niilista do espírito de época. A filosofia, justamente porque capta um momento determinado em seu pensamento, não pode jamais se reduzir à mera expressão de uma época, a um sintoma de uma cultura ascendente ou decadente...

Published: March 2024

Segundo uma perspectiva cientométrica, objetivamos analisar as produções e relações da Abordagem Centrada na Pessoa (ACP) e da Gestalt-Terapia, para entender como esse campo está organizado no Brasil. Inicialmente, explicamos as noções de cientometria e campo, segundo Bourdieu. Em seguida, apresentamos o método bibliométrico empregado conforme a linguagem R, a partir do seu pacote Bibliometrix e o que desenvolvemos como uma nova função para coletar metadados. Os resultados e discussões apontam para: uma ampliação de publicações entre 2008-2017, em decorrência das recentes expansões educacionais, de periódicos (virtuais) e eventos acadêmicos fenomenológicos; variedade de revistas de orientação humanista e geral, sendo as duas mais producentes sediadas em instituições gestálticas extra-acadêmicas; ocorrência da Lei de Lotka, em que poucas pessoas constantemente publicam muitos estudos sobre ACP e Gestalt-Terapia, enquanto muitos outros autores publicam ocasionalmente; fatores de dominância mesclados entre autores consolidados no campo e novas figuras de produção; existência de nove grupos isolados, dois pares de grupos inter-relacionados e uma predominância de grupos com produções pontuais. Concluímos com sugestões para outras pesquisas no campo e uma metanálise sobre a Gestalt-Terapia Centrada na Pessoa
Sobre O Porvir: Interpretações Do Tempo Em Rollo May

Published: March 2024

Entre os muitos temas abordados por Rollo May (1909-1994), expoente estadunidense da Psicologia Existencial, encontra-se o tempo como experiência existencial e subjetiva; isto é, a temporalidade como espaço de organização da própria subjetividade do humano, dando ênfase na capacidade contínua deste mesmo humano de extrapolar seu “presente” criando novas significações em direção ao “futuro”. Neste breve estudo pretende- -se expor um certo “conjunto de pensamentos” em que se mesclam tanto uma apresentação da perspectiva de May a respeito do tempo, o qual incide na questão do “futuro” como um fio condutor fundamental para o tecido mesmo da atividade psíquica humana (quer se trate de condições ditas “normais”, como as que são designadas como “transtorno”) e horizonte de sua existência; assim como algumas interpretações, a partir da ótica proporcionada por May, de algumas sintomáticas e adoecidas expressões de como o humano tem lidado com o tempo na atualidade.

Published: March 2024

O texto discute a ideia de Hermenêutica Formativa, baseada na filosofia de H.G.Gadamer, apresentando estudos empíricos sobre as experiências docentes quanto ao cuidado e ao sofrimento psíquico de alunos. Foram tomadas algumas vivências de docentes apreendidas nos percursos do componente curricular “Núcleo Temático em Políticas da Vida” (NT), a partir das atividades do Grupo de Trabalho (GT) “Metodologia Viva”, que aborda a qualidade das relações vividas pelos docentes, bem como a relação entre educação e saúde e sua indissociabilidade entre o cuidar e o educar. Participaram das atividades do GT vinte professores da educação básica. Como dispositivos de informações foram utilizados entrevistas, questionários e duas rodas de conversas vivenciadas no próprio espaço escolar em busca de interpretação acerca das experiências docentes. Em relação à análise, optou-se pela articulação da análise de conteúdo do tipo “tema emergente” e a análise fenomenológica do tipo círculo hermenêutico. Os horizontes interpretativos se organizaram em: A desvalia do docente cansado; O cuidado docente interrompido e suas possibilidades de resgate; Phronesis: saberes e estratégias docentes. Nesse processo inventivo de si, a ação de cuidado passa pelas relações e práticas de diálogo. Nessa arte de se interpretar e cuidar, o próprio ato educativo se faz na relação.
KONSEP PENDIDIKAN MENURUT AL-QUR’AN HADIS
Authors: Syahroni Muhammad Irfan
Published: March 2024

Istilah pendidikan dalam konteks Islam pada umumnya mengacu kepada term tarbiyah, tazkiyah dan ta’dib. Dari ketiga istilah tersebut term yang populer digunakan dalam praktik pendidikan Islam adalah tarbiyah. Sedang term tazkiyah dan ta’dib jarang digunakan. Padahal kedua istilah tersebut telah digunakan sejak awal pertumbuhan pendidikan Islam. Di dalam al-Qur’an dan hadis tidak disebutkan secara rinci dan jelas tentang konsep pendidikan, tapi secara emplisit aspek pendidikan banyak termuat. Oleh karena itu, penelaahan konsep pendidikan mutlak dilakukan untuk memperkaya khazanah pendidikan Islam. Konsep tarbiyah, tazkiyah dan ta’dib merupakan sesatuan untuh dalam kerangka bangunan pendidikan Islam. Tarbiyah memuat kandungan upaya sadar akan pemeliharaan, pengembangan seluruh potensi diri manusia sesuai dengan fitrahnya dan perlindungan menyeluruh terhadap hak-hak kemanusiaannya. Sedangkan tazkiyah membersihkan jiwa dari sifat-sifat tercela dan mengisinya dengan sifat-sifat terpuji. Adapun ta’dib merupakan proses pembinaan kepribadian dan sikap moral (afektif) dan etika dalam kehidupan

Authors: Hamdalo James , Rodriguez-Martinez Luis A. , Dominguez-Garcia Maria I.
Published: March 2024

This research investigates the intricate dynamics of English language acquisition within multilingual environments, considering both the unique challenges and potential benefits presented by these settings. One of the main hurdles is cross-linguistic interference, where proficiency in native languages may hinder English language understanding or production. Alongside this, the cognitive load of juggling multiple languages may impede the learning process. Nevertheless, multilingual environments can foster cross-linguistic transfer, allowing learners to utilize existing linguistic skills to aid their English acquisition. Moreover, these settings can enhance intercultural competence and motivation by offering insights into various cultures and lifestyles. Understanding these dynamics can inform pedagogical practices, enabling educators to maximize multilingualism's benefits while addressing its challenges. The study also acknowledges the influence of individual learner attitudes, societal factors, and the status of English within multilingual societies on language learning outcomes. It highlights the significant role of teachers in employing effective, culturally responsive strategies and leveraging technological advancements to cater to the unique needs of learners in multilingual contexts. This research underscores the complexity of English language learning in multilingual settings, emphasising the need for well-informed, holistic approaches that recognize cognitive and cultural aspects of multilingualism, apply effective teaching methodologies, and utilize digital resources. Through such approaches, learners can flourish in their English language learning journey despite the challenges posed by their multilingual environments.

Published: March 2024

The study evaluated the knowledge management capabilities of the National Commission on Muslim Filipinos (NCMF) in Region IX-B, including Basilan, Sulu, and TawiTawi, during the Fiscal Year 2023. The survey comprised 100 workers with five years of employment and a bachelor's degree, the majority of whom were female and under thirty. In terms of knowledge process, infrastructure, intellectual capital, and performance, the results demonstrated that the region possessed high knowledge management capabilities in relation to organizational survival and sustainability of competitive strength. Profile variables such as age, gender, length of service, and educational attainment did not significantly mediate the assessment of knowledge management capability. The study supports the Omotayo, F.O. (2015) model of knowledge management capability, which consists of dimensions such as knowledge management process, infrastructure, intellectual capital, and organizational performance. The group of employees who assessed the region's knowledge management capability in terms of organizational performance was probably the same group that assessed it in terms of knowledge management infrastructure, process, and intellectual capital.

This study aimed to determine the extent of workplace collaboration and overall job satisfaction of elementary school teachers in Indanan North District, Ministry of Basic, Higher and Technical Education-Sulu during the School Year 2023-2024. The study involved 100 teachers, mostly female, married, aged 31-40 and 41-50 years, with master's degrees and 5 years or less of teaching experience. On average, school administrators and teachers had good work relationships, and teachers were very satisfied with their teaching jobs. The study found that other variables, such as gender, age, civil status, and length of service, did not influence how teachers assessed the extent of workplace relationships. The study also found that the group of teachers who perceived workplace collaboration as very good likely had the same overall job satisfaction. The study supports Abun et al.'s Workplace Relationship Model, which posits that workplace relationships are characterized by employer-employee relationships and employeeemployee relationships. Employer-employee relationships involve open communication between supervisors and subordinates, while employee-employee relationships involve mutual respect and cooperation in community programs or activities.
Biståndshandläggares erfarenheter av sociala problem hos äldre medborgare – En kartläggning om de sociala problemens synlighet
Authors: Mac Innes Hanna , Lundälv Jörgen
Published: March 2024

De senaste åren har fattigdom, skuldsättning, hemlöshet och våld i nära relationer ökat hos äldre personer. Socialtjänstens verksamhet lyder under flera lagrum. Portalparagrafen i socialtjänstlagen är kanske den mest synliga men inte den mest överordnade. Förutom att bedöma behovet av insatser har socialarbetare en skyldighet att enligt förvaltningslagen hänvisa den enskilde till rätt myndighet. Därför har biståndshandläggare en avgörande roll för äldre personer med social problematik. Artikeln fokuserar på i vilken utsträckning biståndshandläggare möter olika sociala problem och vilka aktörer de hänvisar till när det multikomplexa sociala problemet inte kan hanteras inom handläggarrollen. Baserat på resultaten från denna studie vill vi argumentera för att definitionen av socialt arbete måste breddas för att omfatta multikomplexa sociala problem hos den äldre befolkningen.

Published: March 2024

Synapse is the fundamental structure for neurons to transmit information between cells. The proper synapse formation is crucial for developing neural circuits and cognitive functions of the brain. The aberrant synapse formation has been proved to cause many neurological disorders, including autism spectrum disorders and intellectual disability. Synaptic cell adhesion molecules (CAMs) are thought to play a major role in achieving mechanistic cell-cell recognition and initiating synapse formation via trans-synaptic interactions. Due to the diversity of synapses in different brain areas, circuits and neurons, although many synaptic CAMs, such as Neurexins (NRXNs), Neuroligins (NLGNs), Synaptic cell adhesion molecules (SynCAMs), Leucine-rich-repeat transmembrane neuronal proteins (LRRTMs), and SLIT and NTRK-like protein (SLITRKs) have been identified as synaptogenic molecules, how these molecules determine specific synapse formation and whether other molecules driving synapse formation remain undiscovered are unclear. Here, to provide a tool for synapse labeling and synaptic CAMs screening by artificial synapse formation (ASF) assay, we generated synaptotagmin-1-tdTomato (Syt1-tdTomato) transgenic mice by inserting the tdTomato-fused synaptotagmin-1 coding sequence into the genome of C57BL/6J mice. In the brain of Syt1-tdTomato transgenic mice, the tdTomato-fused synaptotagmin-1 (SYT1-tdTomato) signals were widely observed in different areas and overlapped with synapsin-1, a widely-used synaptic marker. In the olfactory bulb, the SYT1-tdTomato signals are highly enriched in the glomerulus. In the cultured hippocampal neurons, the SYT1-tdTomato signals showed colocalization with several synaptic markers. Compared to the wild-type (WT) mouse neurons, cultured hippocampal neurons from Syt1-tdTomato transgenic mice presented normal synaptic neurotransmission. In ASF assays, neurons from Syt1-tdTomato transgenic mice could form synaptic connections with HEK293T cells expressing NLGN2, LRRTM2, and SLITRK2 without immunostaining. Therefore, our work suggested that the Syt1-tdTomato transgenic mice with the ability to label synapses by tdTomato, and it will be a convenient tool for screening synaptogenic molecules.
Sensorimotor mechanisms selective to numerosity: evidence from individual differences

We have previously shown that after few seconds of adaptation by finger-tapping, the perceived numerosity of spatial arrays and temporal sequences of visual objects displayed near the tapping region is increased or decreased, implying the existence of a
sensorimotor numerosity system
(Anobile et al., 2016). To date, this mechanism has been evidenced only by adaptation. Here we extend our finding by leveraging on a well-established covariance technique, used to unveil and characterize “channels” for basic visual features such as colour, motion, contrast, and spatial frequency. Participants were required to press rapidly a key a specific number of times, without counting. We then correlated the precision of reproduction for various target number presses between participants. The results showed high positive correlations for nearby target numbers, scaling down with numerical distance, implying tuning selectivity. Factor analysis identified two factors, one for low and the other for higher numbers. Principal component analysis revealed two bell-shaped covariance channels, peaking at different numerical values. Two control experiments ruled out the role of non-numerical strategies based on tapping frequency and response duration. These results reinforce our previous reports based on adaptation, and further suggest the existence of at least two sensori-motor number channels responsible for translating symbolic numbers into action sequences.

The dimeric two-pore OSCA/TMEM63 family has recently been identified as mechanically activated ion channels. Previously, based on the unique features of the structure of OSCA1.2, we postulated the potential involvement of several structural elements in sensing membrane tension
1
. Interestingly, while OSCA1, 2, and 3 clades are activated by membrane stretch in cell-attached patches (i.e., they are stretch-activated channels), they differ in their ability to transduce membrane deformation induced by a blunt probe (poking). In an effort to understand the domains contributing to mechanical signal transduction, we used cryo-electron microscopy to solve the structure of
Arabidopsis thaliana
(At) OSCA3.1, which, unlike AtOSCA1.2, only produced stretch- but not poke-activated currents in our initial characterization
2
. Mutagenesis and electrophysiological assessment of conserved and divergent putative mechanosensitive features of OSCA1.2 reveal a selective disruption of the macroscopic currents elicited by poking without considerable effects on stretch-activated currents (SAC). Our results support the involvement of the amphipathic helix and lipid-interacting residues in the membrane fenestration in the response to poking. Our findings position these two structural elements as potential sources of functional diversity within the family.

The contributions of individual genes to cell-scale morphology and cytoskeletal organization are challenging to define due to the wide intercellular variation of these complex phenotypes. We leveraged the controlled nature of image-based pooled screening to assess the impact of CRISPRi knockdown of 366 genes on cell and nuclear morphology in human U2OS osteosarcoma cells. Screen scale-up was facilitated by a new, efficient barcode readout method that successfully genotyped 85% of cells. Phenotype analysis using a deep learning algorithm, the β-variational autoencoder, produced a feature embedding space distinct from one derived from conventional morphological profiling, but detected similar gene hits while requiring minimal design decisions. We found 45 gene hits and visualized their effect by rationally constrained sampling of cells along the direction of phenotypic shift. By relating these phenotypic shifts to each other, we construct a quantitative and interpretable space of morphological variation in human cells.

Published: July 2006

A general palladium‐catalyzed alkoxycarbonylation of aryl and heteroaryl bromides has been developed in the presence of bulky monodentate phosphines. Studies of the butoxycarbonylation of three model substrates revealed the advantages of di‐1‐adamantyl‐n‐butylphosphine compared to other ligands. In the presence of this catalyst system various bromoarenes provided the corresponding benzoic acid derivatives (ester, amides, acids) in excellent yield at low catalyst loadings (0.5 mol % Pd or below).

Published: July 2006

The resolution of eight differently substituted trifluoromethylstyrene oxide derivatives was explored using the Aspergillus niger epoxide hydrolase. The obtained results indicate that all (but one) epoxides were efficiently processed by this enzyme, under very mild experimental conditions. The specific activity and the enantioselectivity of the enzyme against each substrate were determined. Circular dichroism analysis was also performed, allowing us to establish the absolute configuration of the products.

We studied the prognostic value of parameters of angiogenesis on bone marrow biopsies in newly diagnosed multiple myeloma (MM) patients. Angiogenesis parameters studied were the microvessel count done manually on light microscopy (MVD‐A), microvessel count done by using computerized image analyzer (MVD‐B), and total vascular area (TVA) measured by computerized image analyzer. One hundred ten newly diagnosed cases of MM treated at Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, were analyzed with respect to clinical features, laboratory findings, histological features, angiogenesis parameters, and responses to the treatment on follow‐up. Twenty age‐ and sex‐matched controls were studied for comparing with angiogenesis of the test cases. Bone marrow microvessels were examined using immunohistochemical staining for CD34. MVD‐A (range 4.9–85.2; mean 28.2; SD 19.4), MVD‐B (range 2.0–26.9; mean 11.7; SD 5.9), and TVA measured in percentage (range 0.1–17.1; mean 2.4; SD 2.5) were measured for test cases (n = 110). Grading of angiogenesis parameters of the test cases were done; such that angiogenesis parameters of controls (taken as baseline) were grade I. There was a statistically highly significant correlation between (MVD‐A vs MVD‐B, pcc = 0.92; MVD‐A vs TVA, pcc = 0.78; MVD‐B vs TVA, pcc = 0.76). The myeloma cases had significantly higher angiogenesis parameters when compared with controls (Kruskall‐Wallis test, P < 0.001). “Complete responders” (n = 38/110) had significant lower angiogenesis (Mann‐Whitney U test, P < 0.001) than “nonresponders” (n = 72/110). On treatment follow‐up “rapid disease progressors” had the highest levels of angiogenesis (mean rank for MVD‐A = 84.7, MVD‐B = 82.1, and TVA = 81.1). On multivariate (logistic regression) analysis, factors found to have independent prognostic significance in complete responders (adjusted odd ratio (95% CI, P value)] were: (a) MVD‐B grade I [0.134 (0.10–0.16, P < 0.001)], (b) clinical substage A [0.163 (0.12–0.19, P = 0.008)], (c) Bartl's histological stage II & I [0.262 (0.2–0.32, P = 0.021)], (d) MVD‐A grade I [0.28 (0.22–0.36, P = 0.03)], (e) β2 microglobulin levels less than 3,400 ng/dl [0.31 (0.23–0.42, P = 0.04)]. Kaplan‐Meier survival analysis for myeloma‐related death (n = 16) shows a mean survival time (in months) of 24.75; SE = 3; 95% CI = 21–28. We conclude that MVD (particularly MVD‐B) is a very good predictor for the complete response in patients of MM and should be done routinely on bone marrow biopsies. Am. J.

Published: July 2006

The aim of this study is to investigate the association between three polymorphisms of the interleukin‐1 (IL‐1) gene complex and schizophrenia. We genotyped 228 outpatients with schizophrenia (DSM‐IV criteria) and 419 unrelated healthy controls. The following polymorphisms were analyzed: IL‐1α −889 C/T, IL‐1β +3953 C/T, and IL‐1RA (86 bp)n. No significant differences in genotype or in allelic distribution of the Il‐1α, IL‐1β, and IL‐1RA polymorphisms were found. Estimated haplotype frequencies were similar in both groups. Our data do not suggest that genetically determined changes in the IL‐1 gene complex confer increased susceptibility for schizophrenia. © 2005 Wiley‐Liss, Inc.
