The growth of carbon nanostructures from vegetable oils using a modified conventional approach is a simple and environmentally friendly technology with controllable features. The goal of this study is to develop a simple and environmentally friendly process for making carbon nanoparticles using commercially available, low-cost vegetable oils. The technique involves the controlled burning of “Mustard”, “Olive”, and “Linseed” oils using the traditional clay lamps and collecting the carbon soot on a ceramic plate. The prepared carbon nanoparticles were purified through sonication and subjected to characterization using powder X-ray diffraction, SEM, Fourier transformed infrared, Thermogravimetric and differential scanning calorimetric analyses. The average particle size of carbon nanoparticles as investigated by powder X-Ray Diffraction analyses was found to be 18, 24, and 57 nm for mustard, olive and linseed oils respectively. SEM analyses revealed the surface morphology of these carbon nanostructures as spherical particles. Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) providing knowledge about the thermal stability of these carbon nanoparticles. The synthesized carbon nanoparticles were screened for antibacterial activities against different species (e.g., Pseudomonas aeruginosa, Streptococcus haemolyticus, Proteus refrigere and Staphylococcus aureus) and fruitful results have been obtained.

In this paper, two not-difficult inequalities are invented and proved in detail, which adequately describe the behavior of discrete logical functions xor(x1, x2,…, xn) and and(x1, x2,…, xn). Based on these proven inequalities, infinitely differentiable extensions of the logical functions xor(x1, x2,…, xn) and and(x1, x2,…, xn) were defined for the entire ℝn. These suitable extensions were applied to systems of logical equations. Specifically, the system of m logical equations in a constructive way without adding any equations (not field equations and no others) is transformed in ℝn first into an equivalent system of m smooth rational equations (SmSRE) so that the solution of SmSRE can be reduced to the problem minimization of the objective function, and any numerical optimization methods can be applied since the objective function will be infinitely differentiable. Again, we transformed SmSRE into an equivalent system of m polynomial equations (SmPE). This means that any symbolic methods for solving polynomial systems can be used to solve and analyze an equivalent SmPE. The equivalence of these systems has been proved in detail. Based on these proofs and results, in the next paper, we plan to study the practical applicability of numerical optimization methods for SmSRE and symbolic methods for SmPE.

Strategies for Implementation of Disability Mainstreaming Policies in Public Libraries, in Reference to Kenya National Libraries, Meru, Kisumu and Nakuru Branches
Authors: Onchagwa Dorine Mogoi , Wambiri Daniel 
Published: May 2022

Persons living with disabilities numbers (PWDs) is growing globally (WHO, 2011). According to research conducted by Kenya National Survey for people with disabilities, indicate prevalence of disability as 4.6 percent. Visual, physical, hearing, and mental disabilities are the most common. In 2008,the International Convention on the Rights of Persons with Disabilities was enforced as disabled persons were experiencing discrimination in absorption to employment and promotion rates, remuneration and access to training, credit facilities and other resources and this led to their rare participation decision making in economic concerns. With the provision of a paradigm shift by UN Convention's, PWDs are now seen as persons capable of asserting their rights, making decisions based on free and informed consent, and participating fully in society. Disability mainstreaming issues have recently gained more attention around the world, with efforts to integrate people with disabilities critical to achieving the United Nations SDG and Kenya Vision 2030. Despite Kenya Government’s efforts in developing policies, constitution and regulations provisions in protecting persons living with disabilities, they still face problems associated with marginalization in Kenya. Many public institutions’ areas of service are not disable friendly facilities. The crux of this study therefore is to investigate strategies for implementation and mainstreaming of disability policies in public libraries. The study shall investigate existing government policies, management commitment, resource allocation, challenges experienced and possible solutions. Qualitative and quantitative data was collected using descriptive research design. The study was carried out at the Meru, Kisumu and Nakuru, Kenya National Library Services branches. Stratified and Purposive sampling was used in selecting respondents from different sections and departments. Questionnaires were used as data collection instruments, as well as document analysis and observation schedules. Descriptive statistics was used to analyze the data and the Statistical Package for Social Sciences (SPSS) software was used in analysis and graph generation.
Influence of Credit Availability Disbursement on the Level of Savings Among Members of Deposit Taking SACCO’s in Nyeri County
Authors: Karoki Serah Nyamweru , Mungai John 
Published: May 2022

One of the key goals of the SACCO movement is to mobilize savings. However, despite having the largest SACCO sectors in the world, available data shows there is a low personal and household savings rate in Kenya. The majority of Kenyans do not have a savings culture and live each day as it comes. Kenyans are thought to save only 12% of their incomes on average, which is insufficient to support any serious investment in any sector of the economy. The current study therefore sought to assess the influence of credit availability disbursements on the level of savings. This study was guided by the permanent income hypothesis and loanable funds theory of interest. The study adopted a descriptive cross sectional survey research design. The target population was 156,000 active individual members of the 8 deposits taking SACCOs in Nyeri County. The sample of size was 400 respondents derived purposively. To obtain data, the researchers employed a standardized self-administered questionnaire. A pre-test was undertaken in deposit-taking SACCOs in Murang'a County to determine the instrument's reliability and validity. The data was analyzed using descriptive and regression analysis. In the analysis, the Statistical Package for the Social Sciences (SPSS) version 24 was utilized. Tables were used to present the data. Majority of the members agreed that loan ratio/multiplier was applied when granting credit facility. The study concluded that there was a positive significant relationship between credit availability disbursements and member’s savings level in the SACCOs. The study recommended that short-term promotional incentives may be one strategy to encourage people to save more, although evidence on their effectiveness is limited. The study recommends to SASRA to accommodate the total savings and deposits when ranking the performance of deposit taking Saccos other than considering only the total assets parameter.

of the BH shadow. For the Event Horizon Telescope image of Sgr A*, limits on

Δ

are not available due to the sparse interferometric coverage of the 2017 observations, alongside the short variability timescale of Sgr A* compared to M87*. We comment on the results of a recent preprint which purports to have derived new limits on extra dimensions using the deviation from circularity of Sgr A*'s shadow. The latter is quoted to be ≲10% as with M87*, based on the “similarity” of the two shadows, which however is an incorrect assumption. In the immediate future, the simplest tests of fundamental physics from Sgr A*'s image will mostly have to rely on r

The Behavior of HgMn Stars in the Far UV −4: ι CrB A
Authors: Monier Richard 
Published: May 2022

Abstract
The analysis of twelve high resolution SWP spectra of the HgMn star HD 143807 A (ι CrB A) obtained through the large aperture recorded by the International Ultraviolet Explorer reveals that the far-ultraviolet flux of this star remained constant over the various observations with IUE. The TESS lightcurve of ι CrB does not show evidence for periodic variability. The absence of far and mid-UV variability and the reproducibility of the brightness in the V band during the IUE observations precludes the presence of large chemical gradients over the surface of ι CrB at the epoch of the IUE observations. The analysis of six high resolution SOPHIE spectra obtained over three consecutive nights in 2007 March does not show any variations of the lines, either in reduced intensity nor in radial velocity.
Le piège du pitch ou l’ambivalente performance d’un discours spectaculaire
Authors: Gabay-Mariani Laëtitia , Buquet Romain , Bureau Sylvain 
Published: May 2022

Cette contribution propose une réflexion sur les effets ambivalents de la pratique du pitch, outil désormais incontournable des formations à l’entrepreneuriat. Elle s’appuie sur un exercice de déconstruction de cette forme de discours entrepreneurial spectaculaire, en interrogeant son pouvoir symbolique. L’analyse croisée d’entretiens, d’observations et d’expériences entre trois chercheurs en entrepreneuriat a conduit à envisager le pitch comme une narration performée, normée et normative, véhiculant un modèle de l’entrepreneur tel qu’il devrait être (« entrepreneur fictif »), et avantageant par là même un certain type de projets. Tout en soulignant les intérêts de la pratique du pitch, elle met en lumière certains effets problématiques, comme l’homogénéisation du discours, et au-delà, la standardisation des pratiques d’accompagnement entrepreneurial qui en découlent.
Le rôle du discours des porteurs de projets dans la réussite des campagnes de crowdlending
Authors: Ben Slimane Faten , Chaney Damien , Leboeuf Gael , Trabelsi Donia 
Published: May 2022

Cet article étudie l’effet du discours mobilisé par les porteurs de projets pour s’adresser aux communautés de prêteurs sur la réussite des campagnes de prêt. À partir de données collectées auprès de trois des principales plateformes françaises, nous avons identifié, dans un premier temps et grâce à une analyse textuelle automatisée, trois classes de discours : un discours portant sur la situation financière de l’entreprise, un discours axé sur l’équipe dirigeante et un discours portant sur le produit. Dans un deuxième temps, nous avons étudié l’impact de ces trois classes de discours sur la réussite des levées de fonds en utilisant la régression logistique par la méthode du maximum de vraisemblance pénalisé. Les résultats montrent que seul le discours relatif à la situation financière de l’entreprise a un effet positif et significatif sur le succès de la campagne. Codes JEL : L14, L26, G23
Les capacités des plateformes numériques comme maintien de l’équilibre conventionnel : les cas de Uber et Blablacar
Authors: Abel Mathilde 
Published: May 2022

Cet article analyse les capacités des plateformes numériques à travers l’approche de l’économie des conventions. Celle-ci nous permet, d’une part, d’envisager les marchés bifaces comme des conventions d’échange agencées par les plateformes via un processus de triangulation des échanges, et d’autre part, de définir leurs capacités comme étant cognitives et fondées sur des dispositifs sociotechniques. À partir de deux études de cas du secteur du transport de personnes, Uber et Blablacar, nous montrons que la recherche d’un niveau d’équilibre et d’un test de ce niveau constituent, conjointement, les conditions d’exploitation des marchés bifaces, et que la maîtrise organisationnelle de ces conditions qui forgent les capacités des plateformes numériques. Nous construisons une taxonomie des capacités et détaillons celles de ces deux organisations. Codes JEL : L22, D25, L86, L91

A Prospective Study on Clinical Outcome of Primary Nailing in Open Type I to Type IIIA Tibial Diaphyseal Fractures
Authors: Hari Kiran , Srinath K. M. , Daddimani Ravi M. 
Published: May 2022

Background and Objectives:
Tibia is a superficial long bone, with one third of its surface being subcutaneous. An increasing incidence of road traffic accidents, farm accidents, gunshot wound predisposes it for open fracture. Open fractures of the tibia are the most common open long bone fractures. High-energy trauma is the primary mechanism of injury, with over 50% of cases being attributed to road traffic accidents are frequently contaminated. The treatment of open tibia fractures is still controversial. This prospective study was conducted at a tertiary care trauma center to evaluate the functional outcome and complications following primary debridement and nailing in type I to type IIIA open tibia fractures.

Materials and Methods:
A total of 30 patients diagnosed with open tibial diaphyseal fractures, who underwent primary debridement and fixation with intramedullary interlocking nail were included in the study and type III B, type III C open fractures were excluded. Patients were followed for a period of 12 months and assessed using Modified Ketenjian criteria and Johner − Wruhs' criteria.

Results:
Out of 30 patients who underwent primary nailing for open tibia fractures, 66.67% had excellent, 26, 67% good, and 6.66% of patients had fair results. 93.33% of the patients had union within 9 months and 6.66% of the cases had delayed union.

Conclusion:
Primary intramedullary interlocking nailing in open tibia fractures is a good treatment option, it aids early patient mobilization and early resume to work. It avoids multiple surgical procedures and promotes early fracture union.

Published: May 2022

In the olden days, clavicle fractures have been treated with conservative management like strapping and bed rest. Fractures of the clavicle are one of the most common injures of the human skeleton. This study was undertaken to observe the rate of union, functional outcome and complications of fracture middle third clavicle treated with open reduction and internal fixation (ORIF) with precontoured superior plate placement.

Methods:
A total of 30 patients were operated with anatomical precontoured plates from December 2018 to December 2020 and functional outcomes were assessed through 6 months.

Results:
A total of 30 patients were included in the study. There were 27 males and 3 females. The mean age of the patient in the ORIF group was 31.03 years (age between 20 and 50 years). The mean time to union was 15 weeks. In our study, none of the patients had nonunion, implant failure and infection. Four patients developed scar hypertrophy, Three patients developed hypoesthesia below the incision site and one patient developed screw loosening.

Conclusion:
It is possible to obtain a good fracture union, less soft tissue stripping and good patient satisfaction with superior plate placement for fracture middle third clavicle.
