Lack of competencies and skills of managers on the human resource management (HRM) practices in hospital consequently related to quality and outcome of health care services. The overall objective was to assess the practice of human resource management among teaching hospitals in Kathmandu, Nepal. Methods: A cross-sectional descriptive study was conducted in two purposively selected hospitals in Kathmandu, Nepal. Data were collected using structured question among 212 managers and were selected using simple random sampling technique from October 2016 to March 2017. In-depth interview were taken among six corporate level managers. Descriptive analysis was performed. Results: Majority (80.2%) of managers were female, most of them were non-indigenous communities and were from nursing profession (90.1%). Effective management of HRM is spirited for the success of organization whereas half (50%) respondents it effects of all HR activities. Management of human resources is essential to enable the delivery of efficient and effective clinical services and achieve patient satisfaction. Consequently, all health providers, managers as well as health professionals have to know the patient evaluation on these aspects in order to remember how they are important for patients. Hospital HRM authority must be worked for quality of services to entire patients and address those who were not satisfied on currently offering services. This study showed significant differences in the assessment of both staff members and patients and level of offered services in the various departments within same hospital and between hospitals.

Os métodos para a determinação dos teores de elementos-traço presentes no solo devem proporcionar a exatidão de resultados, baixo custo, praticidade e simplicidade. Objetivou-se neste estudo comparar dois métodos de abertura das amostras, USEPA 3050B e USEPA 3051A, quanto à eficiência de determinação de teores de vanádio no solo. A avaliação foi conduzida com base em amostras de referência NIST 2709A (SRM San Joaquin Soil) e em amostras do horizonte A de classes de solos do estado de Santa Catarina, pertencentes ao banco de dados do Departamento de Solos da UDESC. A abertura das amostras foi procedida utilizando-se os dois métodos supramencionados e a quantificação de vanádio foi efetuada por meio de espectroscopia de emissão atômica por plasma acoplado indutivamente (ICP-OES). Os dados foram analisados por meio de estatística descritiva, analise de correlação e regressão linear, cálculo de coeficientes de concordância e teste de identidade, utilizando-se de planilha eletrônica e software R. Na média, os maiores teores de vanádio nas amostras de referência foram obtidos com o método USEPA 3051A (93,50%), comparativamente ao método USEPA 3050B (69,10%). Nas amostras de solos, os valores dos coeficientes de correlação linear (0,96), de determinação (0,92), do índice de concordância de Willmott (0,87) e do coeficiente de confiança de Camargo e Sentelhas (0,83) indicaram alto grau de associação/concordância entre os dois métodos testados. No entanto, o teste de identidade proposto por Leite e Oliveira indicou que há diferença (P < 0,05) quanto à eficiência de determinação dos teores de vanádio em solos entre eles.

O gafanhoto aposemático Tetrataenia surinama (Linnaeus, 1764) (Orthoptera, Acrididae, Leptysminae), se alimenta e desenvolve seu ciclo de vida associado à macrófita aquática Montrichardia linifera (Arruda) Schott, (Araceae), planta conhecida como Aninga, considerada tóxica para vertebrados e que se encontra amplamente distribuída na região Amazônica, inclusive nos centros urbanos. Este trabalho teve como objetivo determinar, por meio de análise química, a composição mineral do gafanhoto T. surinama e relacioná-la com a composição mineral de sua planta hospedeira M. linifera (Aninga). A coleta dos gafanhotos e da Aninga foi feita na área da Universidade Federal Rural da Amazônia (UFRA), Belém, Pará, no período de maio a julho/2017. Os exemplares coletados foram transferidos para o Insetário da Universidade do Estado do Pará (UEPA), onde receberam dieta exclusiva com folhas de Aninga por 21 dias (NUNES, 1989). A análise química, para determinação da composição mineral do gafanhoto foi realizada no laboratório de análises químicas da Coordenação de Ciências da Terra e Ecologia (CCTE), do Museu Paraense Emílio Goeldi (MPEG). As análises químicas do gafanhoto (em triplicata) seguiram o protocolo de Amarante et al. (2009), que já foi empregado na análise química da Aninga. Os resultados obtidos para o gafanhoto deram positivos para Cálcio (Ca), Magnésio (Mg), Ferro (Fe), Cobre (Cu), Zinco (Zn), e Manganês (Mn). O elemento de maior concentração em T. surinama foi o Cálcio para os machos (668,44 mg/kg), fêmeas (559,18 mg/kg) e imaturos (ninfas) (819,85 mg/kg) e a menor concentração nos machos foi de Manganês (44,43 mg/kg) enquanto que nas fêmeas e ninfas foi de Cobre (43,26 mg/kg e 48,44 mg/kg, respectivamente). Na Aninga, o elemento de maior concentração foi o Manganês (3612,23 mg/kg), que a torna uma ‘planta tóxica’. Embora T. surinama se alimente de Aninga (sua planta hospedeira), ele possui baixa concentração de Manganês e, por isso, não pode ser considerado tóxico, caso seja ingerido por consumidores na cadeia alimentar. Portanto, as 'cores de advertência' (aposematismo) existente no gafanhoto, não indica toxicidade, mas pode representar uma estratégia de sobrevivência, produto do processo de coevolução de T. surinama com sua planta hospedeira M. linifera.

A produção de mudas de pequizeiro (Cariocar brasiliense) por meio de sementes é afetada diretamente pela presença de dormência. Em função disso, o presente trabalho teve como objetivo avaliar técnicas de quebra de dormência de unidades de dispersão (putâmen) de pequi, utilizando métodos mecânicos (escarificação) e tratamento fitohormonal com ácido giberélico. Para tal, instalou-se em viveiro um experimento com delineamento de blocos ao acaso, em esquema fatorial 3x3 e quatro repetições. Os frutos foram coletados maduros logo após sua queda. Retirou-se o epicarpo e mesocarpo, obtendo o putâmen. Os tratamentos consistiram na utilização de putâmens escarificados e não escarificados, imersos por 96 horas em solução de ácido giberélico nas doses de 1, 2 e 3 g dm-3. Após o surgimento da primeira plântula, determinou-se o tempo médio de emergência de plântulas, índice de velocidade de emergência e o percentual de emergência. As doses de ácidos giberélicos influenciaram na porcentagem de germinação, independentemente do método de escarificação, sendo as doses de 2 e 3 g.dm-3 que proporcionaram melhores resultados. Os tratamentos com escarificação em 1 e 2 faces da semente proporcionaram melhores resultados de percentagem de germinação, em comparação ao não escarificado.

Pese a la alarma social que suscita el comportamiento delictivo en menores, los datos reflejan la baja prevalencia de estos hechos. No obstante, es y ha sido de suma importancia para la intervención social el estudio de modelos explicativos de dicho comportamiento, tanto por la elaboración de estrategias preventivas como por la intervención psicoeducativa con estos. El modelo de triple riesgo delictivo pretende explicar la etiología de estos comportamientos antisociales y delictivos, precisamente, para conseguir dichos fines y partiendo de diferentes modelos y teorías integradoras. Este trabajo pretende explicar este modelo en la práctica profesional con estos menores, y concluye con la aparición de las tres fuentes de riesgo: riesgos individuales, carencias prosociales y oportunidades delictivas en estos. El modelo de triple riesgo delictivo tiene en cuenta la acumulación de riesgos, pudiendo identificar la estimación de riesgo delictivo futuro.
In-Situ Precipitated Calcium Carbonate Paper Filler Material: A Review
Authors: Dölle Klaus 
Published: March 2022

Since the invention of the paper by in 105 CE to Chai Lun many improvements have been made to the paper product we know today. Today a paper machines can be over 600 m long and 11.5 m wide, running at speeds of over 2000 m/min, and producing up to 4,500 metric tons per hour. Paper as we know it today, can be characterized as an orthotropic thin plate with a thickness of over 500 μm and a basis weight of over 500 g/m² requiring additives to achieve the needed paper properties.
Calcium carbonate based filler additive materials have approximately 70% market share in North America, and can be added to a maximum of 20 to 25% based on fiber material.
In the 1970s a shift from acid to neutral papermaking started which made it possible to use precipitated calcium carbonate in the paper manufacturing process. New printing technologies required paper with superior properties. This led to an increase in filler content and specially designed filler particles. The in-situ precipitation and filler manufacturing processes are known today, can be divided into (i) mechanical method which uses high shear and centrifugal forces to load the fiber pores with the filler particle, (ii) a chemical method which is the common method in producing precipitated calcium carbonate in a solution since the 1980’s for papermaking applications, and (iii) a combination of the mechanical and chemical method which precipitates the calcium carbonate particles on and into the fiber material present in the solution.
All research on various in situ precipitation processes, including patented technologies, since the 1970’s showed that the achieved handsheet properties have higher brightness and opacity values as well as a coarser surface structure, lower smoothness and gloss. In-Situ processes showed improvements for the paper manufacturing process in regards to physical and mechanical handsheet paper properties.
However, no commercial applications of this process have been found at present time. However, mixing the filler particles with the pulp suspension and storing this suspension in the headbox feed chest, for a specific time, applies indirectly in-situ principles in today’s paper making process operations.

Background: Cancer persists as a major health issue globally due to its high rate of morbidity and mortality. Skin cancer is the most common cancer and accounts for at least 40% of cancer cases worldwide. Search for tumour-selective and novel anticancer compounds with lesser side effects remains a major focus of cancer research. Saraca asoca is a traditional Indian medicinal plant, known to have anti-cancer, anti-menorrhagic, anti-oxidant, anti-oxytocic and anti-microbial activities. Though phytoconstituents of the Saraca asoca leaves, bark, and flowers have been reported in few studies, the cytotoxic potential of Saraca asoca flowers has not been evaluated.
Aim: To evaluate the proapoptotic potential of Saraca asoca flower extract on skin cancer cell line.
Materials and Methods: In this present study, the cytotoxic potential of Saraca asoca flower extract (10 to 60μg/ml) was evaluated by MTT assays in B16-F10 skin cancer cells. According to the MTT assay, we determined the optimal doses (IC-50: 30µg/ml) which were used for further analyses. Analysis of changes in cell morphology is examined by a phase-contrast microscope. The impacts of Saraca asoca in B16-F10 cell death were also determined by AO/EtBr dual staining under a fluorescence microscope.
Results: In our study, the cell viability assay results showed that 50% of growth inhibition was observed at 30 μg/ml concentration of Saraca asoca flower extract treated B16-F10 cells, which has been taken as an inhibitory concentration (IC-50) dose value and fixed for further experiments. The morphological changes in B16-F10 skin cancer cell line with the treatment of Saraca asoca at 30 μg/mL for 24hrs has significantly altered the morphology of B16-F10 cell lines. AO/EtBr dual staining results showed the early apoptotic cells having bright orange areas of condensed or fragmented chromatin in the nucleus after Saraca asoca flower extract treated skin cancer cells.
Conclusion: The results of this present study showed that the flower extracts of Saraca asoca were cytotoxic and induced apoptosis to the cancer cells at a concentration of 30µg/ml at the 24th-time point.
