Authors: Cárdenas María Fernanda , López Ramírez Cristina , Mejía Juan Diego , Escobar Jhon Fredy
Published: April 2019

Transpiration is a key variable in water balance. Sap flow measurement methods allow to estimate transpiration at plant level, but scalable at the stand, river basin or ecosystem level. This requires recording data continuously, for which there are commercial devices, but they are specialized and expensive. This document shows that it is possible to integrate a data capture, management and storage system, as a counterpart to a commercial system such as Campbell's CR-100, for measuring and recording environmental variables, with a notable reduction in costs. The methodology used to develop a device for the estimation of sap flow using the heat ratio method, the design of the Arduino-based  electronic circuit and the software, with register 13-64-171 of the Dirección Nacional de Derechos de Autor, is presented.

Published: April 2019

Currently, energy demand and environmental pollution have boosted the evolution of different environment friendly technologies for the development of clean and renewable energies. That is why scientific research allows us to demonstrate the use of solid state based devices implementing temperature changes by electric induction. Given the above, a combined thermic generation system is taken into consideration, consisting in an environmentally friendly thermoelectric generator and refrigerator, wich is fueled and controlled by an electric fluid. Therefore, this study gives an approch and mathematic demonstrations to the concepts of greater relevance about the thermoelectric device and the effects of greater incidence, responsible for giving advantageous characteristics to the implementation of Peltier cells as a basic device in a cooling system for smaller applications, maintaining an ecological system, clean and without detrimental effects to the ozone layer, since there is no C02 emissions into the atmosphere.
A Convex Approximation for Optimal DER Scheduling on Unbal-anced Power Distribution Networks
Authors: Serna-Suárez Iván David
Published: April 2019

The increase of solar photovoltaic penetration poses several challenges for distribution network operation, mainly because such high penetration might cause reliability problems like protection malfunctioning, accelerated decay of voltage regulators and voltage violations. Some control strategies avoid such drawbacks at the cost of not fully exploiting the available energy. Existing solutions based on mathematical programming solve a 3-phase ACOPF to optimally exploit the available energy, however, this might increase all reliability problems above if done carelessly. As a solution to optimally exploit DERs (like local photovoltaic and storage systems) without compromising the network reliability, this paper presents a novel algorithm to solve the 3-phase ACOPF as a sequence of convex Quadratically Constrained Quadratic Programs. Results show that this solution has a lower voltage unbalance and computation time than its non-linear counterpart, furthermore, it converges to a primal feasible point for the non-linear formulation without major sacrifices on optimal DER active power injections.

Correlations between some economic larval traits of silkworm
Authors: Gündüz M. , Şahan Ü.
Published: April 2019

Abstract. Silkworm, Bombyx mori L. is an economic insect that has great importance on cocoon and silk production. The development of sericultural industry depends on quality and yield in terms of qualitative and quantitative silkworm characters. Mature larval weight and silk gland mass are important factors in silkworm breeding. Silk gland mass has significant impact on the synthesis of silk protein in fifth larval stage. The investigation was conducted to evaluate the correlations between silk gland mass and mature larva weight of M and ZF (China), and N and ZB (Japan) lines and their hybrids MxN, ZFxZB. In this research, silkworm lines and hybrids were reared at the laboratory with 600 silkworm larvae for each four lines and their hybrids to determine these silkworm traits. Analysis of variance indicated that the mean values in Chinese lines and hybrids were found to be significant (P<0.01) for mature larva weight. On the other hand, mean value of silk gland mass was determined as important for Chinese, Japanese lines and hybrids (P<0.01). Both mature larva weight and silk gland mass have positive correlation in Chinese lines (r=0.659) and hybrids (r=0.643) (P<0.01). Otherwise, the correlation between these characters were not found to be significant for Japanese lines. As a result, it is necessary to search the correlation between different characters and to protect the genetic diversity in silkworm lines.

Published: April 2019

Abstract. The study examined the effect of improved seed technology adoption on small-scale sorghum farmers’ productivity in Kebbi State, Nigeria. Multistage sampling technique was employed in determining the sample size from the sample frame, 240 respondents were sampled using proportionate sampling technique. Data for the study were collected using structured questionnaire containing open and closed ended questions. The data collected were analyzed using descriptive statistics and multiple regression analysis. The results indicated that the sorghum farmers adopted Samsorg-5, Samsorg-14 and Samsorg-17 improved seeds with Samsorg-5 accounting for 64.6% level of adoption, thus ranking first. The multinomial logit regression model showed that the probability of adopting one or two improved sorghum varieties increased with the farmers’ educational level, sex, farm size and labour usage in the study area. The results further revealed that the average cost of Samsorg seeds was negative and statistically significant at one percent probability level across the groups which implies that the probability of adopting any of the improved sorghum varieties reduced with its cost. The results also indicated that Samsorg-5, Samsorg-14 and Samsorg-17 improved seeds positively affected farmer’s production and productivity at 5% levels of probability. This indicated that a percentage increased in the use of these improved seeds led to an increase in the production and productivity of sorghum farmers in the study area. Also, the influence of farm size and fertilizer on output and productivity were positive and statistically significant at 1% levels of probability. The results further revealed that, the topmost constraints faced were inadequate extension services and low level of formal education at 92.1% and 56.7% ranking 1st and 2nd, respectively. Therefore, the study recommended an action-oriented plan to reach the small scale farmers with adequate information on agricultural practices to promote adoption of improved seeds in order to increase their level of productivity. Agricultural policies should be directed at making inputs available at subsidized rate, on time and at the required level. Credit facilities should be made accessible at single digit interest rate to enable them efficiently utilize inputs in order to increase their productivity level.

Authors: Madugu A.J.
Published: April 2019

Abstract. This study investigated the food security status of female-headed households (FHHs) in Mubi north local government area (LGA) of Adamawa State, Nigeria. Specifically, the socio economic characteristics and determinants of household food security status of respondents were tested. Structured questionnaire was used to collect data from 80 female headed households using simple random sampling technique from five districts of Mubi north LGA. Analytical tools used were the food security index (FSI) and Binary Logit Regression Analysis. The results showed that majority (57.9%) of the respondents were middle aged, having 1-5 persons in their household and cultivating about 1-3 hectares of land. It further showed that most of the respondents (63.8%) were food insecure. The result further showed that age, household size, educational status, and access to input were significant and therefore regarded as the major determinants of food security in the study area. It also showed that extension service was not significant and thus not a determinant of food security among the respondents. The study concluded that female headed households in the study area were food insecure; it was thus recommended that NGOs, CSOs and other actors should focus more on agricultural activities by providing inputs so as to improve food production and household food security index, furthermore, the result showed that extension service did not influence food security status of respondents, thus, private extension service providers should be established to assist the government in the provision of intensive extension contact/services, this can help to improve food production and subsequent food security status of respondents.

Background and aims

Pathological buying (PB) is a behavioral addiction that presents comorbidity with several psychiatric disorders. Despite the increase in the prevalence estimates of PB, relatively few PB instruments have been developed. Our aim was to assess the psychometric properties of the Spanish version of the pathological buying screener (PBS) and to explore the associations between PB, psychopathology, and personality traits.

Methods

A total of 511 participants, including gambling disorder (GD) and eating disorder (ED) patients diagnosed according to DSM-5 criteria, as well as healthy controls (HCs), took part in the study.

Results

Higher PB prevalence was obtained in ED patients than in the other two study groups (ED 12.5% vs. 1.3% HC and 2.7% GD). Confirmatory factor analysis (CFA) verified the 13-item structure of the PBS, and indexes of convergent and discriminant capacity were estimated. CFA confirmed the structure in two factors (excessive buying behavior and loss of control) with excellent internal consistency (α = .92 and .86, respectively). Good convergent capacity was obtained with external psychopathology and personality measures (positive correlations with novelty seeking and negative associations with self-directedness and harm avoidance were found). Good discriminative capacity to differentiate between the study groups was obtained.

Discussion and conclusions

This study provides support for the reliability and validity of the Spanish adaptation of the PBS. Female sex, higher impulsivity, and higher psychopathology were associated with PB.
Developing the Criterion of Exchange Quotation Prediction Quality for Metal Trader Decision Support
Authors: Paytyan Karen
Published: April 2019

The main purpose of this article is to present a criterion for assessing the quality of forecasting nickel exchange prices to support the decision-making of a metal trader, taking into account the specifics of their commercial activities. We consider the commercial operation of a metal trading company, which consists in purchasing a metal with a view to its resale in 14 days. Most of these operations occur in nickel-rich alloys, which suggests that their prices are largely determined by nickel quotes on the LME (London Metal Exchange). Therefore, metal traders need forecasting models with a long lead time series with a high degree of volatility. One of the first assumptions suggests that in order to ensure profitable trading, it is necessary, first of all, to correctly predict the direction of price change.
On the other hand, it is intuitively clear that the better the model, the more likely it will be to guess the further trend. However, it remains an open question as to what accuracy of the forecast will provide the so-called break-even point to the metal trader. This work is devoted to the search for this facet. Another assumption that the quality of any model depends on the degree of volatility of the predicted time series helps to find the exact point from which we can talk about the possibility of successful trading. Taking into account these provisions, a criterion has been developed for assessing the quality of forecasting models, which makes it possible to state with high probability that the use of a forecast that meets it will ensure commercial success for the metal trader. It is also important to note that the quality of the model can be judged only after comparing its accuracy with the characteristics of the considered time series. The prediction error itself does not give an exhaustive picture of the quality of the applied model.

This article was migrated. The article was not marked as recommended. Introduction: A vocation is predisposition of an person to enter a certain profession or occupation, or to develop skills in certain arts; vocation among medical students is important to reducing their rates of leaving their studies in a subject where training is both lengthy and expensive. Objective: To evaluate the vocational orientation of students admitted to the Faculty of Medicine at Agostinho Neto University in 2013 and assess whether there is any correlation between student achievement during the selection process and students vocation. Methods: an observational, cross-sectional descriptive study was conducted on the vocational orientation of medical students; the study population consisted of all students admitted in 2013. Results: Only 19.4% (n=19) demonstrated that they had a vocation for medicine and among those students there was an imperfect negative correlation between the results of the vocational test and the access exam. Conclusion: The results of the study showed that the majority of students have vocational profiles that are incompatible with the medical profession.

Published: April 2019

In preparation for a call for proposals, a workshop was held with representatives from the Institution of Civil Engineers’ (ICE) Research, Development and Innovation towards Engineering Excellence Panel, academia, Innovate UK, the Engineering and Physical Sciences Research Council, Highways England and the consulting industry. The overarching theme that emerged was that infrastructure does not adequately take into account the value that could be gained from its long-term service provision. This has therefore been selected as an appropriate cross-cutting theme for the ‘Spring 2019 Call for Proposals for the ICE’s Research and Development Enabling Fund’. The findings from this research and development initiative are required to be presented at a half-day event, as well as to form the subject of papers and/or briefings to be published in relevant parts of the ICE Proceedings and other forms of dissemination, thus ensuring that they are brought to the attention of ICE’s members. This briefing is a summary of challenges that need to be embraced by the profession, as revealed by the workshop discussions and which therefore reflect the collective views of all those at the workshop (who are listed in the Acknowledgements).
Parametric study and alkali–silica reactivity-induced expansion model of ASTM C 1260
Authors: Islam Mohammad S. , Ghafoori Nader
Published: April 2019

ASTM C 1260 (accelerated mortar bar test (AMBT)) is the most popular and time-effective method to evaluate the alkali–silica reactivity of an aggregate. In this study, the test specimens (mortar bars) of AMBT were prepared with six aggregate groups having six different rock mineralogies (limestone, dolomite, andesite, dacite, basalt and dolomitic limestone) and three dosages of cement alkalis (0·42, 0·84 and 1·26% equivalent sodium oxide (Na2Oeq)). The bars were immersed in the three strengths (1·0, 0·5 and 0·25 N) of sodium hydroxide (NaOH) solution at 80°C and were tested for changes in length for the test duration of 98 d. This experimental study and analytical approach were used to (a) investigate the three factors of solution concentration, cement alkali and test duration of ABMT on mortar expansion, and (b) propose a model in predicting mortar expansion of each aggregate group. The study showed that the alkali solution contributed significantly to mortar expansion, followed by test duration, and then followed by cement alkali. The predicted mortar expansion evaluated by the proposed models showed a very good agreement with that obtained by the experimental procedure.

Published: April 2019

Justificativa e conteúdo: A cólera é uma doença infecciosa intestinal aguda causada pela toxina do Vibrio cholerae. A transmissão é oral-fecal e ocorre predominantemente em ambientes aquáticos contaminados. Pode ser fatal, mas é facilmente evitada e tratada. Associa-se a sua propagação com a falta de saneamento básico pois cresce exponencialmente nesses ambientes. O diagnóstico é clínico-epidemiológico, laboratorial com meios seletivos para o microrganismo e teste rápido, este último não é sensível e nem especifico. O tratamento é com sais de reidratação oral e antibioticoterapia, indica-se a suplementação com zinco. Existe vacinação para Vibrio cholerae, e essa é a melhor medida para o controle da doença. As pesquisas em cólera já não são mais frequentes, pois ela é considerada uma doença de países que não são desenvolvidos. Conclusão: Nesse contexto, ainda são necessárias pesquisas sobre sistemas de esgoto, monitorização de efluentes, vigilância da qualidade da água de abastecimento público e vigilância da qualidade de alimentos.

Quando juntamos as palavras: “direitos” a “humanos”, a quais humanos estamos nos referindo e a quais vidas deixamos de fora, considerando as relações de saber-poder que excluem e hierarquizam vidas? Ao se tratar da história dos direitos humanos (DH) é recorrente o uso de uma história contínua, que concebe os direitos dentro de uma linha evolutiva, relacionada a uma suposta expansão da consciência humana. A partir desta lente que o liberalismo concebeu os chamados direitos humanos como direitos universais e alienáveis, os quais progressivamente foram positivados em leis e constituíram-se na base do ordenamento jurídico dos Estados Modernos. A vigilância disciplinar do corpo e a biopolítica como governo da população em nome da saúde nasceu concomitantes ao nascimento do Estado Moderno, oferecendo substrato ao Direito público e comercial, à inflação jurídica e punitiva da gestão das existências, no mercado dos direitos e da vida.

SPECIFIC ASPECTS OF SCALES FORMATION ON THEMATIC MAPS IN CONDITIONS OF CARTOGRAPHY COMPUTERIZATION
Authors: Bondarenko E.
Published: April 2019

The article is devoted to the consideration of specific aspects of scales formation on thematic maps in modern conditions of automation of cartographic works. The special aspects are revealed by systematization of the functionality of the software, which relates to geographic information systems (GIS).
The author summarized the existing knowledge regarding the development of scales for cartographic image methods, which provide their use in the practice of thematic mapping. The classification of scale formation methods is presented according to the degree of automation with distribution: automatic methods for distributing numerical series by graduation (including using “smart cartography”) and interactive (user-defined), which improve and expand the automatic. Two groups of cartographic image methods are identified depending on the degree of accuracy in the display of objects, phenomena or processes (geometrically accurate and schematic), which imply the use of scales. The factors of scales development (nature of mapping phenomena affecting the choice of the image method, the purpose of the map, the definition of its completeness and accuracy, the quality of the source data, the geographical specificity of the territory) are defined.
The author formulated the principles for the formation of algorithms for calculating numerical intervals of graded scales, as well as the possibilities of “smart cartography” for the development of their continuous analogues. Additional techniques are proposed for interactive distribution of the number of series at intervals: the rounding the boundaries of intervals; the choice of the initial round number more than the initial number of the series; the choice of around finite number less than a finite number of the series; the definition in the legend of the actual starting and final numbers of the series; the definition in the legend of the upper and lower bounds of the intervals are following one after another.
In this article, the author improved the model of interaction between automatic and interactive methods of scales forming based on certain features of their development for creating of thematic maps.

Published: April 2019

In the current step of Ukraine development and reinforcement of EU integration the analysis of the positive foreign experience of European countries, in the first instance, neighbour countries, which are EU members, such as Poland, is of great importance. In this article, particular qualities of environmental politics’ organization and environmental preservation activities in Ukraine and Poland were analyzed. The characteristics of systems of controlling environmental politics in both countries are demonstrated. Similarities in the understanding of basic priorities of governmental institutions in environmental preservation’s sphere were elucidated in the process of exploring main vectors of environmental preservation activities both in Ukraine and in Poland. The followings belong to this vectors: preservation and rational using of natural resources, protection of valuable components of environment and elements of nature( national parks, nature reserves, natural landmarks, estimated plant and animal species, preservation of parks, resorts and green zones in localities, protection of population’s life and health. Environmental preservation is considered as a governmental institutions’ activity, which is directed on natural balance saving, that is needed to provide a comfortable living environment and the right for using natural resources and reserving its quantitative and qualitative conditions. The analysis of specifications of managing the environmental system in Poland showed that besides its own governmental managing system country uses accepted in EU institutional mechanism in environmental reservation sphere, which is realized on three levels: general, special and functional. In the process of exploring it was clarified that the prior tasks of international collaboration in environmental reservation sheer are developed and guarantee of actions for bilateral ecological security. The main questions in Ukrainian and Polish collaboration are: monitoring of condition of separate environmental components; decrease of boundary atmosphere pollution; providing inventory of pollution sources, control of ecologically safe manufacturing, conduction consultations about organization of events dedicated to prevention of emergencies and reduction of negative consequences of environmental pollution, development of actions for reserving biodiversity of flora and fauna. One of the most successful projects between Ukrainian, Belorussian and Polish governments is the formation of boundary biospheric reservation “West Polesie” which consists of three Biospheric reservations “Shatsky” (Ukraine), “Prybuzhskoe Polesie” (Belorussia), “West Polesie” (Polish). The signed agreement of association with the EU will accompany future improvements of countries’ collaboration and of the environmental reservation system in Ukraine.
Influência do Avanço da Ferramenta e do Uso de Fluido de Corte na Rugosidade em Usinagem de Torneamento Cilíndrico Externo de Alumínio
Authors: Marques Clauber Roberto Melo , Castagnel Paulo Henrique
Published: April 2019

As características superficiais de uma peça usinada são resultantes de vários fatores, entre eles pode-se citar o material da ferramenta utilizada, geração de calor e parâmetros de corte. Este trabalho teve como objetivo principal verificar a influência do avanço da ferramenta e do uso de fluido de corte em usinagem analisando a rugosidade de superfícies de peças de alumínio usinadas por torneamento cilíndrico externo, em um equipamento CNC Romi Centur 30D com comando Siemens, variando-se a velocidade de avanço da ferramenta, assim como a usinagem a seco e com fluido de corte. Foi realizada uma análise da caracterização química por Espectrometria de Massa para identificar a constituição do material utilizado. Foi executado o processo de usinagem em 10 peças de alumínio, com velocidade de corte de 220 m/min em todos os testes, variando-se o avanço da ferramenta (0,1, 0,15, 0,2, 0,25, 0,30 mm/rot), e para cada valor de avanço diferente foi realizado um ensaio à seco e um com fluido de corte. Após a usinagem as peças foram analisadas utilizando-se um rugosímetro Mitutoyo modelo SJ-310, para medição da Rugosidade Média (Ra) resultante. Concluiu-se que para valores de avanço de ferramenta de até 0,25 mm/rot, com velocidade de corte de 220 m/min, a presença do fluido de corte na usinagem não apresentou melhoria no resultado final. Somente com avanço de 0,30 mm/rot a presença do fluido de corte se mostrou mais eficiente que a usinagem a seco.Palavras-chave: Usinagem. Alumínio. Rugosidade. AbstractThe surface characteristics of a machined part is the result of several factors, among them the tool material used, heat generation and cutting parameters. This work had as main objective the analysis of the surface roughness of aluminum parts machined by external cylindrical turning in a CNC Romi Centur 30D equipment with Siemens command, varying the speed of tool advance, as well as the dry machining and with cutting fluid. An analysis of the chemical characterization was performed by Mass Spectrometry to identify the constitution of the material used. The machining process was carried out in 10 pieces of aluminum, with a cutting speed of 220 m/min in all tests. The tool advance (0,1, 0,15, 0,2, 0,25, 0,30 mm/rot), and for each different feed rate a dry test and one with cutting fluid were performed. After machining, the parts were analyzed using a Mitutoyo model SJ-310 rugosimeter to measure the resulting Average Roughness (Ra). It was concluded that for tool feed values up to 0.25 mm/rot, with a cutting speed of 220 m/min, the presence of the cutting fluid in the machining did not show improvement in the final result. Only with an advance of 0.30 mm/rot the presence of the cutting fluid was more efficient than the dry machining. Keywords: Machining, Aluminum, Roughness.

A proposta deste artigo é avaliar o sistema de medição em um estudo de caso utilizando a ferramenta Gage R&R, com o objetivo de descobrir a variação das medições, podendo ser por Repetibilidade e/ou Reprodutibilidade. Na ferramenta DMAIC utilizada no Seis Sigma, a etapa Medir é usualmente a mais complicada e demorada pela baixa qualidade dos sistemas de medições da maioria das empresas. Pretende-se uma revisão literária para melhor conhecimento do assunto, assim, a primeira etapa foi a criação de um procedimento para a empresa em estudo. Após a elaboração do procedimento, os colaboradores foram treinados e a gerência definiu as principais inspeções que afetam o produto para a realização do estudo. Em seguida, a ferramenta foi aplicada e cada saída foi analisada comprovando a presença de variações que poderiam não ser consideradas. Palavras-chave: Sistema de medição. DMAIC. Gage R&R. Abstract The proposal is to evaluate the measurement system in a case study using the tool Gage R & R in order to find the variation of the measurements may be for repeatability and / or reproducibility.

Background: Perceived health (PH) is a subjective assessment of the health and it is a strong, independent and reliable predictor of morbidity, mortality. It includes so many aspects that are difficult to capture clinically such as incipient disease, physiological, psychological reserves. We assessed the impact of diabetes mellitus (DM), hypertension (HTN), co-morbidity and other associated factors on the general health (GH) dimension of the PH of the patients attending the outpatient department (OPD), Inpatient department (IPD), rural health training centre (RHTC) and urban health training centre (UHTC) of Shri Ram Murti Smarak Institute of Medical Sciences (SRMS, IMS), Bareilly.Methods: PH status of the patients was assessed by the GH dimension of the physical component summary of PH using the 36-Items short form health survey (SF-36).Results: The impact of morbidity deteriorate the GH score but hypertensive patients scored poor results as compared to those with DM and comorbid patients (p>0.05). Age was inversely related with GH scores but male gender, higher education (p<0.05) and good occupation were all associated with higher GH score. There was not much influence of geographical area on the GH scores but urban score slightly better and the association was insignificant (p>0.05).Conclusions: Male young patients from urban area, educated and good job performed better score for GH and association was significant for education and occupation. The presence of morbidity and co-morbid condition deteriorate the GH of the patients. The impact of various socio-demographic factors on the PH status was also evident in the study.
Do our medical undergraduates need to develop research skills? Assessing perceptions, attitudes and skills of medical undergraduates
Authors: Patel Neha A.
Published: April 2019

Background: The development of research capacity at undergraduate level is essential to produce good quality researchers in the long run. The core curriculum must ensure that relevant and appropriate research expertise is attained by all graduates who are then provided with a suitable foundation from which they can develop such specialized research skills as may be required in their careers.Methods: A cross sectional study was conducted in Terna Medical College, Nerul, Navi Mumbai from May 2016- September 2016. All students of second and third year who willingly participated were included in the study. Preformed pretested and validated proforma was used. For checking attitudes a standard attitudes towards research scale was been used which contained 32 questions.Results: 74.9% said that research methodology should be the part of curriculum. 37.7% said that they would like to opt a carrier as a researcher. 70.6% students either identified no opportunities, gave no response or didn’t know about opportunities. Biggest barriers identified were lack of knowledge (36.5%), lack of time (34.7%), lack of infrastructure (25.1%). Correlation coefficients between ATR sub-scales were also calculated.Conclusions: Students’ want to conduct research at undergraduate level and want incorporation of research methodology in curriculum. Lack of knowledge, time and resources are common barriers while opportunities, majority are not aware about it. Though students find research difficult and are anxious about it, they have positive attitude towards conducting research.

Background: Ganglion is the one of the common soft tissue swellings in the hand and wrist. Treatment options available include reassurance, nonsurgical means like aspiration with or without steroid or hyaluronidase injection and surgical or arthroscopic excision. All current treatment options produce suboptimal results. This study endeavours to compare the outcome and recurrence rate and other complications after treatment of wrist ganglion by aspiration and methylprednisolone injection by double Intravenous cannula versus single needle technique.

Methods: A prospective comparative clinical study was done with a total of 72 patients. 36 patients in group 1 were treated with double intravenous cannula technique and 36 patients in group 2 were treated with single needle technique. All the patients were followed up for 6 months to look for recurrence and any complication. The patient’s age, sex and various characteristics of the ganglion cyst like side, site, size, etc. were recorded.

Results: In group 1, recurrence was seen in 6 patients (15.7%) while in group 2, recurrence were seen in 14 (38.8%) patients. There was statistical significant difference between the two groups with p value of 0.04. No complication was seen in both groups due to methylprednisolone injection.

Conclusions: Inspired by the results we advise to use aspiration and methylprednisolone injection by double intravenous cannula technique in the treatment of wrist ganglion before any surgical intervention. It is safe, simple, cost effective method and is less invasive and less time consuming with recurrence rate comparable to surgical and arthroscopic interventions.
