A pandemia do Covid 19, nos anos de 2020 e 2021, resultou em um alto índice de desemprego em todo o Mundo e no Brasil. Diante da redução da renda, pessoas se viram impulsionadas a ingressar no empreendedorismo por necessidade, enfrentando dificuldades para a sobrevivência e crescimento. O cenário impactou especialmente as mulheres, cujos negócios foram paralisados devido às restrições, mudanças nos padrões de consumo e vivenciaram a necessidade de conciliar o trabalho e a gestão das famílias.Frente a esse problema, o projeto de extensão da aceleradora Arretadas, realizado nos anos de 2020 e 2021, teve como objetivo apoiar mulheres microempreendedoras formais e informais nas zonas periféricas do Litoral Sul da Bahia, Brasil. Com base na metodologia da pesquisa ação, o projeto ofereceu mentorias individuais e coletivas e acesso a pequenos fundos de crédito rotativo.Foram atendidas 20 mulheres empreendedoras, por meio de encontros semanais individuais e coletivos. O público-alvo priorizou mulheres, mães e/ou autodeclaradas negras, e/ou indígenas, e/ou LGBTQIAPN+, com renda familiar mensal de até dois (2) salários mínimos. Dentre os principais resultados alcançados, destacam-se: a efetiva participação de 19 mulheres inscritas no ciclo de aceleração, o engajamento de 20 voluntárias profissionais, a satisfação de 73% das participantes com o impacto das mentorias, o fornecimento de assessorias que contribuíram para a consolidação dos negócios, o aumento das vendas e a elevação da autoconfiança das empreendedoras envolvidas. Além disso, o projeto resultou na consolidação de uma rede de colaboração entre mulheres empreendedoras no Sul da Bahia.

Published: January 2024

Coconut oil production is the eminent agro based industries in Tamil Nadu. The matured coconut water was considered as a waste. Coconut oil industries discharge considerable amount of waste coconut water having very high values of Biochemical Oxygen Demand (BOD) to the extent of 29,000 mgl-1, the wash water about 3,000 mg. and Total Solids (TS) of 5.45 ± 0.35%. Coconut water contains most nutrients required for microbial growth. The pH of coconut water is 6.1. The Total Suspended Solids in coconut water is found out as 0.0028 g/ml. The Total Dissolved Solids is 0.8014 g/ml, Total Solids is 0.8042 g/ml and Volatile Soluble Solids is 99.5 %. A laboratory scale batch type anaerobic digester (Air tight 2 litre plastic bottles) was set up for the experimental purpose for a retention time of 35 days. Coconut water, water and cow dung were mixed in different proportions (5 treatments). Each treatment was replicated 3 times. Biogas volume and biogas composition were measured at 5:30 pm every day. Remarkable volume of biogas production was noticed between 12th and 16th days. Maximum biogas volume of 976. 67 ml was noticed for the combination of 1:1 (Cow dung: Coconut water) with methane content of 53 %. For the combination of 2:1:1 (Cow dung: Coconut water: Water) the maximum volume of biogas production is 833.3ml with methane content of 31 %. For the combination of 1:1 (water: Cow Dung) the maximum volume of biogas produced is 133.3 ml with methane content of 48 %. The biogas produced from different ratios was tested for its flammability. It was seen that blue flame is produced and the flame is last for few seconds for all ratios but the maximum amount of flame was produced from the sample which contains maximum amount of Coconut water than other samples.

Authors: Pandey Rishi Nath , Kumar Dharmendra , Kumar Sunil , Kumar Arvind , Verma Pradeep Kumar 
Published: January 2024

The increasing prominence of rapeseed-mustard on the global stage as vital oilseed crop is attributed to its high yield, low moisture requirements, cost effective production, and adoptability to diverse farming condition indicating the potential for a forthcoming yellow revolution role in India's oilseed production, facing challenges from various factors affecting yield and seed quality. Notably, white rust stands out as a significant biotic stressor, causing substantial losses in both yield and seedily, 17–34% yield particularly in oil content. To address this, utilizing resistant varieties is the most cost-effective and environmentally friendly approach for disease management. However, the available resistant sources are limited. In a recent study during the Rabi seasons of 2021-22 and 2022-23, thirty rapeseed mustard genotypes were assessed under white rust prevalent conditions. Out of 30 genotypes tested, none were found to be free of white rust disease infection and none were classified as resistant. However,11genotypes were registered as as moderately resistance, while, 19 genotypes fell under the were in the susceptible category. Promisingly, some genotypes exhibited resistance to white rust, offering potential for developing superior cultivars to effectively manage the disease in regions where mustard cultivation is prevalent.
Aims: The study aimed to evaluate 30 rapeseed-mustard genotypes during the Rabi sessions of 2021-22 and 2022-23, focusing on their resistance to white rust. The primary objective was to identified genotypes with potential resistant traits, contributing to the development of superior cultivars for effective white rust management in regions where rapeseed-mustard cultivation is prominent.
Study Design: Randomized Block Design.
Place and Duration of Study: Experimental field of the Department of Plant Pathology, College of Agriculture, BUAT, Banda session 2021-22 and 2022-23.
Results and Conclusion: None of the tested genotypes were found to be entirely free from white rust infection, and none of these achieved under resistance. However, the study identified 11 genotypes as moderately resistance and 19 genotypes fell into the susceptible category. Despite the challenges posed by white rust, sum genotypes demonstrated resistance, offering promising potential for the development of advanced cultivars. This finding holds significant for regions where rapeseed-mustard cultivation faces the threat of white rust, providing the basis for future efforts enhancing crop resilience and productivity.

AbstractA rare β‐thalassemia mutation at the splicing junction [namely, G→C in intervening sequence (IVS) I‐1] was found in a Japanese family. The proband and his mother were heterozygous for the mutation. Analysis of mRNA extracted from the reticulocyte‐rich fraction obtained from the proband's mother revealed that the mutant β‐globin gene did not produce any detectable, stable mRNA including exon 1 and exon 2, since the polymorphism in exon 1 on her mutant gene was not detected in the RT‐PCR products.

Published: January 2003

AbstractWe studied the effects of cyclosporin A (CsA) on the erythroid differentiation of human erythroid leukemia cell line K562. After K562 was treated with CsA for 4 days, the percentage of hemoglobinized cells was increased by 3.3 times. Because it was reported p38 MAPK (p38) and ERK are involved in erythropoietin‐induced erythroid differentiation, we studied their roles using specific inhibitors. p38 inhibitor (SB203580) prevented CsA‐induced hemoglobin synthesis in K562 cells, although MEK/ERK inhibitor (U0126) enhanced it by 3.3 times in K562 cells. These results indicate activation of p38 and inactivation of ERK are involved in CsA‐induced erythroid differentiation of K562 cells. Am. J. Hematol. 72:67–69, 2003. © 2002 Wiley‐Liss, Inc.
Autoimmune hemolysis associated with primary biliary cirrhosis responding to ursodeoxycholic acid as sole treatment
Authors: Fuller S.J. , Kumar P. , Weltman M. , Wiley J.S. 
Published: January 2003

AbstractCoombs' positive autoimmune hemolytic anemia (AIHA) has been rarely described in association with primary biliary cirrhosis (PBC). The previously reported cases have responded to treatment with a combination of corticosteroids and ursodeoxycholic acid (UDCA). We report a case of AIHA occurring in association with PBC, which has responded to treatment with UDCA alone. Possible mechanisms of autoimmune hemolysis in this patient include bile salt induced immune dysregulation and direct damage to red cell membranes by bile salts leading to exposure of neoantigens and development of red cell autoantibodies. A trial of UDCA as a single agent should be considered as initial treatment in this rare disorder. Am. J. Hematol. 72:31–33, 2003. © 2002 Wiley‐Liss, Inc.

Authors: Pullarkat Vinod , Bass Randall D. , Gong Jerald Z. , Feinstein Donald I. , Brynes Russell K. 
Published: January 2003

AbstractMyelofibrosis is characterized by reticulin fibrosis of the bone marrow with resulting features of myelophthisis. Besides hematopoietic malignancies and other neoplasms involving the bone marrow, myelofibrosis has been described in association with autoimmune disorders, especially systemic lupus erythematosus. We describe the clinicopathologic features of a primary form of autoimmune myelofibrosis (AIMF) in patients who do not have systemic lupus erythematosus or another well‐defined autoimmune syndrome. Absence of marked splenomegaly, peripheral blood cytopenias with mild teardrop poikilocytosis and leukoerythroblastosis, bone marrow lymphoid aggregates, and presence of autoantibodies are some of the salient features of primary AIMF. AIMF should especially be differentiated from chronic idiopathic myelofibrosis, a neoplastic myeloproliferative disease. Primary AIMF appears to have an excellent prognosis, with all patients reported in this series responding to a short course of corticosteroid therapy. Am. J.

AbstractWe reviewed the clinical characteristics, treatment, and outcome of 67 children with localized and 212 with disseminated large‐cell lymphoma (LCL) treated during a 20‐year period in 5 consecutive Children's Cancer Group (CCG) non‐Hodgkin's lymphoma (NHL) trials. Clinical outcomes for patients treated on the four earlier studies with moderate‐dose chemotherapy administered over 12–18 months were compared with patients treated most recently with short, intensive therapy. Median age at diagnosis was 12 years (range: 0–19 years). Male to female ratio was 1.8:1.0. Five‐year event‐free survival (EFS) was 92% ± 3.3% and 50 ± 3.5% for patients with localized LCL and disseminated LCL, respectively. After adjustment for lactate dehydrogenase (LDH), age at diagnosis, and BM involvement, short and intensive therapy as delivered on the most recent study, CCG‐5911, was associated with an improved outcome (P< 0.05) compared to the four previous studies. Elevated LDH (≥500 IU/L) at diagnosis and young age (<5 years) were both significant independent predictors of poorer long‐term EFS (P< 0.05). Long‐term survival after relapse or other treatment failure was only 31% ± 4.7%. In summary, more recent shorter and intense therapy appears to be associated with superior event‐free survival for children and adolescents with disseminated LCL. Large numbers of patients treated with shorter and intense therapy are required to confirm these preliminary observations. Am. J. Hematol. 72:53–63, 2003. © 2002 Wiley‐Liss, Inc.
Synthesis and electrochemical characterization of polyurethane with fixed redox‐active units in hard segments

Published: January 2003

AbstractElectrochemically active polyurethanes containing ferrocene units in hard segments (PU–H–Fc) have been synthesized and identified by 1H‐NMR spectra. Electrochemical properties of PU–H–Fc blending with lithium perchlorates were investigated by cyclic voltammetry (CV) and compared with that of polyurethane with ferrocene units in polyether soft segments (PU–S–Fc) and of ordinary polyurethane blending with ferrocene (PU–B–Fc). The apparent formal potentials were found to be similar. The results illustrated that the original redox property of ferrocene was maintained when it was covalently linked to the hard segment as well as to the soft polyether main chain. The peak separation in PU–S–Fc was much greater than in PU–H–Fc, demonstrating that the softness and flexibility of the PEO chain was maintained by fixing the redox units on the hard segments instead of on the soft segments, and the diffusion rate of redox units was increased because the migration of the active substance was enforced by the motion of the polymer chain. The peak position and peak separation of PU–H–Fc were similar to those of ordinary polyurethane blending with ferrocene. In the PU–H–Fc system the physical loss of admix redox molecules by migration can be avoided and the diffusion rate of redox units maintained. This is highly desirable in many electrochemical systems. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 1555–1561, 2003
Effect of the doses and nature of vegetable oil on carbon black/rubber interactions: Studies on castor oil and other vegetable oils
Authors: Kukreja T. R. , Chauhan R. C. , Choe S. , Kundu P. P. 
Published: January 2003

AbstractThe effects of additives in various vegetable oils on the physical, mechanical, and adhesion properties of carbon black/rubber compounds were studied. Various doses of castor oil and some other oils such as paraffin oil, vegetable oil 1, and cashew nut shell liquid (CNSL) at a fixed dose (1 phr) were used. With an increase in the castor oil content, the modulus, tear strength, and tensile strength increased, whereas the hardness and adhesive strength exhibited little variation up to 1 phr. Beyond 1 phr castor oil, the modulus, tear strength, and hardness decreased, whereas the adhesive and tensile strengths increased up to 2.5–3 phr and then decreased. Therefore, castor oil seemed to behave as a coupling agent up to 1 phr and as a coupling agent and a plasticizer in the range of 1–3 phr; beyond that, the main role of castor oil was plasticization. When various oils at a fixed dose (1 phr) were compared, it was found that the vegetable oils exhibited enhanced properties in comparison with those of paraffin oil. In addition, both of the unsaturated oils (castor oil and vegetable oil 1) enhanced physical and mechanical properties in comparison with saturated paraffin oil. CNSL exhibited the best adhesion properties against mild steel and galvanized iron substrates. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 1574–1578, 2003
Melt fracture, melt viscosities, and die swell of polypropylene resin in capillary flow
Authors: Huang Jan‐Chan , Tao Zhenghong 
Published: January 2003

AbstractThe melt fracture, shear viscosity, extensional viscosity, and die swell of a polypropylene resin were studied using a capillary rheometer and dies with a 0.05‐cm diameter and length/radius ratios of 10, 40, and 60. A temperature of 190°C and shear rates between 1 and 5000 s−1 were used. A modified Bagley plot was used with consideration of pressure effects on both the melt viscosity and end effect. The shear viscosity was calculated from the true wall shear stress. When the true wall shear stress increased, the end effect increased and showed critical stresses at around 0.1 and 0.17 MPa. The extensional viscosity was calculated from the end effect and it showed a decreasing trend when the strain rate increased. Both the shear and extensional viscosities correlated well with another polypropylene reported previously. The die swell was higher for shorter dies and increased when shear stress increased. When the shear rates increased, the extrudate changed from smooth to gross melt fracture with regular patterns (spurt) and then turned into an irregular shape. In the regular stage the wavelength of the extrudates increased when the shear rate increased. The frequency of melt fracture was almost independent of the shear rate, but it decreased slightly when the die length increased. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 1587–1594, 2003
Polymerization of ϵ‐caprolactone initiated through powders of biological and nonbiological glasses

Published: January 2003

AbstractEight biomedical glasses and three commercial glasses, as finely divided powders, were tested as initiators for the ring‐opening polymerization of ϵ‐caprolactone in bulk and in vacuo at 185°C. All the glass powders were able to initiate the polymerization, along with Pyrex, which was totally inert toward the monomer as the inner surface of a phial. The obtained polymers were examined with Fourier infrared transform spectroscopy and atomic force microscopy. The molecular weights were measured by viscometry in CHCl3. The presence of a fraction of the polymer firmly linked to the glass was quantitatively checked by the determination of the weight loss from the residues of the extraction with CHCl3 after calcination in a kiln at 945°C. The molecular weights and weight losses per unit surface were elaborated mathematically so that a possible correlation between these properties and the atomic compositions of the glasses could be better investigated. Two possible initiation mechanisms, induced by the hydroxyls present on the glass surface, were proposed: one for free poly(ϵ‐caprolactone) and one for poly(ϵ‐caprolactone) linked to the glass. © 2002 Wiley Periodicals, Inc.

Radiation‐induced GMA/DMAA graft copolymerization onto porous PE hollow‐fiber membrane
Authors: Grasselli Mariano , Carbajal M. Laura , Yoshii Fumio , Sugo Takanobu 
Published: January 2003

AbstractRadiation‐induced graft copolymerization is a powerful technique to prepare a grafted chain with the desired properties pending onto the trunk material. In this work, a polyethylene hollow‐fiber membrane was modified by this technique. The monomers glycidyl methacrylate (GMA) and N,N‐dimethylacrylamide (DMAA) were cografted onto macroporous polyethylene hollow fiber with a grafting degree in the order of 200%. DMAA/GMA cografted membranes were compared to GMA grafted ones for the introduction of an amino acid as a specific ligand. Grafted membranes with a copolymer composition between 0 and 2 DMAA/GMA were prepared by soaking them in solutions of different mixtures of monomers. Copolymers were characterized by FTIR and their composition was estimated by the analysis of the ratio of carbonyl signals. Copolymers with a higher proportion of DMAA showed improved hydrophilic properties and higher conversion rates of epoxy groups on phenyalanine ligands than those of the GMA grafted ones. However, copolymers with a DMAA/GMA ratio higher than 1 showed a detrimental effect on the pure water flux. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 1646–1653, 2003
Dynamic mechanical properties of particle‐reinforced EPDM composites

Published: January 2003

AbstractThe dynamic mechanical property of particle‐reinforced ethylene–propylene–diene monomer (EPDM) matrix composites has been studied by using a dynamic mechanical thermal analyzer (DMTA). The individual composite has been reinforced with the various reinforcing particles as follows: silicon carbide particles (SiCps) of 60 μm in average diameter with various volume fractions (i.e., 10–40%); copper (Cu) and aluminum (Al) particles with 20 vol %; and SiCps with 6 and 36 μm in different average diameters with 20 vol % over the total composite volume. It is shown from the experimental results that the dynamic elastic modulus values increase and the composites with 40 vol % SiCps exhibit higher tan δ values through the entire rubbery phase after the glass transition region compared with the composites with lower particle volume percentages. This shows that the composites with 20 vol % Cu particles have the higher dynamic elastic modulus but the lower peak tan δ value than the composites with other particles of 20 vol % do. Scanning electron microscopy results show that the effective particle volume in the composite with Cu particles is higher than the other composites, although the same particle volume fraction of 20% has been used. © 2002 Wiley Periodicals, Inc.
