Published: May 2022

A field experiment was conducted during 2017-18 at Crop Research Centre, G.B.P.U.A.&T., Pantnagar with the objective of developing fertilizer adjustment equations and quantifying doses for achieving targeted yield of hybrid maize (Zea mays L.) by using STCR approach. Response of hybrid maize to four levels of N, P and K and two levels of FYM under different fertility levels was studied. Nutrient requirements (NR) were reported as 2.17, 0.46 and 2.74 kg q-1 for N, P and K, respectively. The contribution of nutrients N, P, and K from fertilizers (%CF) was found as 58.2, 62.7 and 420.4% , from soil (%CS) as 33.1, 26.8 and 22.7%, from organic matter FYM (%CFYM) as 45.2, 14.4 and 239.4% , from fertilizer with FYM (%CF*) as 62.4, 63.5 and 427.6%, respectively. Fertilizer adjustment equations and ready reckoners were developed with and without FYM for different targeted yield and soil test values of N, P and K. It was observed that response of hybrid maize to N, P and K fertilizers was higher when integrated with FYM application as compared to N,P and K alone. The average saving of fertilizer by application of 10 tonnes FYM was 24.52 kg ha-1 N, 7.11 kg ha-1 P and 3.50 kg ha-1 K within the range of soil test value and yield targets on Mollisol.

To investigate the efficacy of various doses of plant growth regulators on vegetative growth and pod yield of broad bean (Vicia faba L.), a field experiment was accomplished at Vegetable Research Farm, B.H.U., Varanasi during the winter season of 2019-20. Ten treatments were evaluated in randomized block design with three replications. Results indicated that the growth parameters like plant height, number of branches/plant significantly increased with foliar spray of gibberellic acid followed by NAA and salicylic acid. The yield attributes like pod width, fresh pod weight, number of pods/plant as well as fresh pod yield significantly enhanced by NAA followed by gibberellic acid and salicylic acid with various concentrations, respectively. The foliar spraying of 120 ppm GA3 tended to produce plant with maximum height (116.4 cm), number of branches/plant (6.3), pod length (7.5 cm), number of seeds/pod (4.6) as well as early 50 % flowering (57.3 days) whereas, spraying of 40 ppm NAA exhibited the maximum pod width (1.3 cm), fresh pod weight (4.6 g), number of pods/plant (87.5) as well as fresh pod yield (105.0 q ha-1) as compared to other treatments. The maximum net return (Rs. 337326.5 ha-1) was recorded with 40 ppm NAA with B: C ratio of 3.65 followed by 30 ppm NAA and 20 ppm NAA. The lowest net income (Rs. 162382.5 ha-1) and B: C ratio (1.76) was obtained from control. The spraying of NAA was found superior in terms of yield and yield attributes as well as benefit cost ratio followed by GA3 and salicylic acid.

Published: May 2022

A field experiment was conducted during kharif seasons of 2016 and 2017 at the Research Farm, ICAR Research Complex for NEH Region, Nagaland Centre to study of the effect of planting geometry and weed management practices on maize (Zea mays L.) based intercropping system. The experiment was laid out in randomized block design with twelve treatments and replicated three times. The results revealed that different planting geometry patterns did not affect the growth and yield attributes at any stage of growth of maize. Growth attributes tended to increase with advancement of growth and maximum values were recorded at 90 DAS. The highest grain and stover yields of maize were recorded as 2.54 t ha-1 and 4.98 t ha-1 from the maize + soybean (2:2) planting geometry. Weed management practices had significant effect over weedy check on plant growth parameters, yield attributes, grain and stover yields except test weight of maize. The highest grain (2.87 t ha-1) and stover yields (5.55 t ha-1) of maize were recorded with two hand weedings at 20 and 40 DAS which was at par with pre-emergence application of pendimethalin @ 1.0 kg a.i.ha-1 + 1 HW at 30 DAS.

Published: May 2022

A study was under taken during kharif season of 2016 at College of Agriculture, Bheemarayanagudi and UAS, GKVK, Bengaluru to estimate the combining ability and investigate gene action involved in inheritance of yield and its components traits of maize inbreds through 20×20 full diallel cross analysis. 380 SCHs synthesized through full diallel mating design were evaluated in simple lattice square lattice design at two locations. Analysis of variance revealed significant differences among the hybrids, parents vs. hybrids and straight crosses for all the characters and among the parents for all the characters except ASI, ear circumference and shelling %. Significant differences were also recorded in reciprocal crosses for all the characters except ear circumference and shelling %. Significant GCA variance for grain yield revealed the role of additive components of genetic variance. SCA variance was also highly significant for all characters except ear circumference and test weight indicating the importance of both additive and non additive components of genetic variance. However, there was predominance of additive gene action recorded for all the characters. GCA: SCA variance ratio was less than unity for all the traits, suggesting the predominance of non-additive gene action. Inbreds MAI 283 and VL 109252 were identified as good general combiners as they registered significant gca effects in positive direction for grain yield and its component traits. Straight cross MAI-283×KDMI-16 and reciprocal cross M 04×KDMI 16 registered highest significant sca effects in positive direction for grain yield along with high and significant sca effects in negative direction for ASI.

Authors:   Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore-641 003, Tamil Nadu, India, T CHITDESHWARI
Published: May 2022

Zinc deficiency in soils and plants is the worldwide problem causing considerable yield reduction and indirectly affects human health due to its lesser concentration in the crop produces grown on zinc deficient soils. Hence to know the effect of zinc supply on the growth, clove yield and Zn accumulation, four field experiments were conducted with varied levels of zinc sulphate (0, 5, 10, 25, 37.5 and 50 kg ha-1) using garlic variety Ooty 1 as test crop on zinc deficient sandy loam soils during the Rabi season of 2018-19. Soils with deficient zinc availability showed better response to different levels of zinc sulphate and application of recommended NPK along with 10 kg zinc sulphate ha-1 was found sufficient and economical in increasing the clove yield of garlic by 20.6 per cent. The same treatment resulted in higher farm income with the benefit cost ratio of 3.28. Slight yield reduction (5-7%) at all the four farms was observed for the higher levels of zinc sulphate addition (37.5 and 50 kg ha-1). The highest soil Zn availability, zinc accumulation and uptake by garlic crop were obtained with the addition of 50 kg zinc sulphate ha-1. Although there was a higher variability in the garlic crop response to zinc levels at all the farms, zinc sulphate addition at different levels considerably improved the growth and yield of garlic and also increasing the zinc accumulation in cloves and plants on zinc deficient soils.

We are happy to announce a new European Journal of Geography (EJG) section titled ‘Geographic Insights in brief’. This initiative complements the new approach of EJG publishing (immediate publication of papers after the end of the review process) The short papers in this section will be published as part of each issue of the journal and will be reviewed only by the editorial team, in order to achieve fast dissemination of new and interesting ideas and applications. This section will accept two kinds of papers: First, papers announcing new ideas, breakthroughs and innovations in all Geographical areas that need to be immediately communicate to all geographers. The authors can later proceed to publish a fully developed traditional paper. Second, brief reports focusing on short, clear and pointed geographical research results and data. These shorter and more digestible items will help geographers to get a better understanding about specific spatial dimensions of environmental, social and economic phenomena and interactions that can feed an ongoing policy discussion with just a small amount of original visual analytics and geographical data. That is, present a smart and successive visualization or datasets, such as cartograms, mental maps, web-GIS platforms, real-time geographies and so on. This process provides new opportunities for intellectual communications and benefits for both researchers and practitioners to present new theoretical and empirical findings from new research and/or innovative geospatial applications. This new EJG section follows the trend in contemporary scholarship on geography to provide open access, inclusive and flexible platforms that express new, vibrant and exciting ideas. The requirements for the new series in EJG are: 1. Scope: European topics in human or physical geography, using cartography, GIS, remote sensing, quantitative or qualitative methods. 2.

Controle de constitucionalidade: análise comparada dos modelos brasileiro e argentino e a união homoafetiva
Authors: Pagliarini Alexandre Coutinho , Moura Genilma Pereira
Published: May 2022

Os direitos fundamentais também são protegidos por meio do controle de constitucionalidade, que harmoniza o sistema jurídico, vinculando a adequação de uma lei ou qualquer espécie normativa aos preceitos constitucionais. Diante dos diferentes modelos de controle judicial de constitucionalidade das leis, como “forte” ou “fraco”, “concentrado” ou “difuso”, este artigo tem por objetivo analisar o controle judicial de constitucionalidade do Brasil e da Argentina, de modo a verificar quais são os pontos em comum dos dois modelos e quais são as principais diferenças entre ambos. Para desenvolver a pesquisa, são analisados os elementos do modelo “difuso” argentino e do modelo “concentrado” brasileiro ilustrados pelo histórico do reconhecimento jurídico das uniões homoafetivas em ambos os países, ou seja, sob a perspectiva do Supremo Tribunal Federal e da Corte Suprema de Justicia de La Nación Argentina; o que permitiu verificar que no caso argentino além da utilização do instrumento “Amparo” na esfera do Judiciário, tendo em vista o efeito inter partes, foi necessário o reconhecimento da união pelo Legislativo, e, no caso brasileiro, o reconhecimento foi mediante o Supremo Tribunal Federal em razão do controle constitucional concentrado com efeito erga omnes e tendo em vista os altos custos de decisão para o Legislativo diante de um eleitorado heterogêneo.

A survey to determine the perceptions of nurses in the eThekwini region towards homeopathy
Authors:   , Allopi Kirasha
Published: May 2022

A survey method was employed to investigate the perceptions of nurses in eThekwini towards homeopathy. The aim of this study was to answer the following questions: What does the nursing community in the eThekwini region know of homeopathy? Does homeopathy have a role to play in a hospital setting in the context of South Africa? The study population was all nurses with 5 years experience or more working in hospitals in the eThekwini region. The sample was drawn from 6 public and 5 private hospitals and included staff nurses and professional nurses. A total of 330 questionnaires were distributed and a total of 200 questionnaires were returned (60.6%). A total of 93 nurses (46.5%) responded from the public sector and 107 nurses (53.5%) from the private sector. The study was carried out using a questionnaire as a measuring tool. The data was analysed using descriptive statistics using frequency tables and bar charts. The Pearson’s Chi Square Test was used on selected data. The majority of respondents were female (94%) and were between the ages of 26-35 and 36-45 years. Most of the respondents had been practising for 6-10 years and 11-15years. 19% of the total number of respondents had never heard of homeopathy and 10% indicated that they were quite familiar with the homeopathic profession. Of those respondents who had never heard of homeopathy, 71.1% were in the public sector and 28.9% in the private sector. Of those respondents who answered that they were quite familiar with homeopathy, 14.3% were in the public sector and 85.7% in the private sector. With regards to legitimacy of homeopathy most nurses working in the private hospitals (60.1%) perceived homeopathy to be a legitimate form of health care as compared to nurses working in public hospitals (39.9%). Generally, both groups considered communication and co-operation with homeopaths to be very poor. In total 79.49% of respondents said it would be beneficial to improve communication between the professions. The majority of respondents (70.06%) perceived that homeopathy does have a role to play in a hospital setting. Only 29.94% of respondents perceived that homeopathy had no role to play in a hospital setting. This indicates that many respondents perceive that integrated medicine is needed in a hospital setting. This study reveals that the respondents had a positive view of homeopathy in general, and were open to learning more about it, and to cooperate with homeopaths. The finding that knowledge of homeopathy is low, and communication between the two professions is poor, can be addressed through suitable publicity and education programmes.
Design and evaluation of alumina/feldspar resin infiltrated dental composite materials
Authors:   , Le Roux Andre Rayne
Published: May 2022

Introduction: Incorporating a feldspar chemical bond between alumina filler particles is expected to increase the wear resistant and flexural strength properties, while reducing flexibility of dental composites. Aims and Objectives: An investigation was carried out to evaluate the influence of the feldspar chemical bonding between alumina filler particles on wear, flexural strength and flexibility of experimental alumina/feldspar dental composites. It was hypothesized that wear resistance and flexural strength would be significantly increased with increased feldspar mass, while flexibility was expected to decrease. Methods: Alumina was chemically sintered and bonded with 30%, 40%, 50% and 60% feldspar mass, silanized and infiltrated with UDMA resin to prepare the dental restorative composite material specimens. Results and conclusions: Significantly higher wear resistant characteristics resulted with increased feldspar mass (p<0.5). Improvements in flexural strength characteristics as the feldspar mass was increased was not statistically different (p>0.5). Flexibility characteristics as the feldspar mass was increased was not statistically different (p>0.5). The alumina/feldspar specimens showed lower flexibility (mm displacement) than SR ADORO (p<0.05). Feldspar chemical bonding between the alumina particles may improve on the wear resistance and Flexibility of alumina/feldspar composites when compared to SR ADORO. This study evaluated the influence of a chemical feldspar bond between alumina filler particles.

To compare trunk flexion and lateral flexion range of motion (ROM) pre-post intervention. To compare the bowling speed of Action Cricket fast bowlers pre-post intervention. To determine the correlation between change in bowling speed immediately post-intervention to change in trunk flexion and lateral flexion ROM immediately post-intervention. To determine the association between change in bowling speed immediately post-intervention and the subjects’ perception of change in bowling speed. Methods: Forty asymptomatic Action Cricket fast bowlers were divided into four groups of ten each. Group 1 received lumbar spine manipulation, Group 2 received thoracic spine manipulation, Group 3 received combined thoracic and lumbar spine manipulation and Group 4 received the sham laser intervention (placebo). Pre- and post-intervention trunk flexion and lateral flexion ROM and bowling speed were measured using a digital inclinometer and a SpeedTracTM Speed Sport Radar. The subjects’ perception of a change in bowling speed post-intervention was also recorded. SPSS version 15.0 was used to analyse the data. Two-tailed tests were used in all cases. Results: Trunk flexion and lateral flexion increased significantly (p < 0.05) post-spinal manipulation. There was a significant increase in bowling speed post-thoracic (p = 0.042) and post-combined manipulation (p < 0.000). A significant yet weak positive correlation (p = 0.003; r = 0.451) was seen in change in bowling speed and change in thoracic flexion and lateral flexion. There was no significant difference in the percentage subjective change by intervention group (p = 0.217). Conclusions: Spinal manipulation is a valid intervention for short-term increase in bowling speed.
Patient perception survey : Durban University of Technology Homoeopathic Day Clinic
Authors:   , Herr Benjamin Jamie
Published: May 2022

Within healthcare, patient satisfaction is a combination of need, expectation and the experience of care being provided. Patient satisfaction is an intermediate outcome, and is an important measure of the quality of the overall care provided. Healthcare which does not satisfy the patient is usually less effective, because less satisfied patients tend not to comply with instructions, they take longer to follow up with appointments and they have a poor understanding of their medical condition (Wilkin, Hallam and Dogget, 1994; AI-Assaf, 1998). The provision of overall quality healthcare for patients is a key motivation for many service providers. Therefore, determining the level of patient satisfaction forms a very important part of managing and fulfilling the patients' healthcare needs (Smith, 2001a). Furthermore, surveys of patient satisfaction form an essential role in assessing public opinion of the service provided. Thus, the evaluation of the service provided by a clinic can be reflected in the degree of satisfaction perceived by individuals receiving the services as elicited by a patient perception survey. This study assess patient’s perception of the service provided at the Homoeopathic Day Clinic (HDC) at the Durban University of Technology (DUT). The use of a self-administered questionnaire to establish patient satisfaction was applied. No names were required and all data has been kept strictly confidential. This information will subsequently be used to improve the quality of the service offered at this facility and increase the degree of patient satisfaction experienced. The sample group of the first 100 patients that consulted the HDC at the DUT between July and November 2007 that voluntarily participated in this study were included in the study by means of convenience sampling.In this study there is generally a high degree of satisfaction with the healthcare and services provided. Areas of particularly high satisfaction are related to patients’ arrival to the clinic where they were both promptly and politely greeted, as well as in relationship to the approachability/friendliness of the Homoeopathic student, and the instructions given on how to take the medicine. Areas that revealed lower degrees of satisfaction are advertising, both in media and by signage, as well as the accessibility of the clinic for disabled patients.

Authors:   , Naidoo Magashri
Published: May 2022

Objective: To determine the current knowledge and perceptions of biokineticists with respect to the chiropractic profession in South Africa. Design: A descriptive design was utilized in a qualitative questionnaire in order to evaluate, in a structured manner, the knowledge and perceptions of biokineticists with respect to Chiropractic. Subjects: The total population size used in the study was 657 (response rate n=78; 11.87%). Outcome Measures: These were based on a questionnaire which addressed biokineticists knowledge of Chiropractic, interaction with Chiropractic, Chiropractic terminology and scope of Chiropractic practice. Results: Of the 657 questionnaires that were mailed, only 78 questionnaires were returned and this gave a response rate of 11.87%. The most frequent view or attitude towards chiropractic was that it had a valuable role in the health care system (64%). About 50% of the respondents believed chiropractors to be greatly competent in examination and diagnosis whilst 40% felt that chiropractors were moderately competent in examination and diagnosis. Nevertheless, the rate of communication between biokineticists and chiropractors was found to be quite high, in this study. All together, 67% of biokineticists had communicated with chiropractors. Of those that had communicated, the communication was rated as positive (94.4%). Of those who had referred patients to chiropractors, 41.8% had received treatment feedback reports and of those who had received reports, 68.8% said they were concise and valuable. Conclusion: The results of this study show that the mean knowledge score was 60%. Thus the overall knowledge of chiropractic was high. The only factor that significantly affected respondents’ knowledge was their self reported knowledge of chiropractic. In congruence with this, the most common attitude towards chiropractic was that it had a valuable role to play in the health care system (64%).

Valoración económica ambiental del ecosistema Manglar majagual en la Reserva Ecológica Cayapas Mataje de la provincia de Esmeraldas
Authors: Bravo Zambrano Daniel Eduardo
Published: May 2022

La Reserva Ecológica Manglares Cayapas-Mataje es un ecosistema donde se desarrollan actividades socio económicas, como recursos culturales, arqueológicos, paisajísticos, y servicios recreativos. Sin embargo, las medidas de conservación dadas por el estado y, comuneros hacia el Mangle, no son los más adecuados. Es por ello, que esta investigación está enfocada en los servicios recreativos del manglar de Majagual, estimando la demanda del bien ambiental, es decir el dinero que se está dispuesto incurrir un visitante por disfrute del bien natural, con la finalidad de determinar la disposición de pago de un individuo por tener acceso al manglar, mediante la estimación del excedente del consumidor. Mediante la aplicación de encuestas en cuatro zonas turísticas de la provincia de Esmeraldas (Las Peñas, Las Palmas, Tonsupa y Atacames), con un total de 1439 personas encuestadas, aplicando el programa de análisis SPSS V24, basado en los servicios recreativos del ecosistema, se obtuvo, la relación de viajes a zonas naturales que realizan los turistas de dichas áreas encuestadas, la disposición de pago por ingresar al Manglar Majagual, estimada es entre USD$ 3 y USD$ 4 adicionalmente motivos para visitarlo y disponibilidad de viaje. La disposición de pago de la población de Majagual por la conservación del ecosistema, en su mayoría fue de USD$ 20 determinado mediante encuestas utilizando el método de valoración contingente. Finalmente se estimó la valoración económica de uso directo realizando un análisis sociodemográfico y económico de la población que habita en Majagual.
