Study on Size-Related Product Quality of Multiscale Central-Punched Cups Fabricated by Compound Forming Directly Using Brass Sheet
Authors: Hu Dien , Zheng Jun-Yuan , Fu M. W.
Published: January 2022

Meso/microforming has gained much more attention in the last decades and is widely used as a reliable method to fabricate meso/micro-scaled metallic components. In this research, a compound meso/microforming system which combines deep drawing, punching and blanking operations was developed to fabricate multiscale central-punched cups by using brass sheets. The parts with three scales were produced by using the brass sheets with various thicknesses and grain sizes to investigate geometrical and grain size effects on the deformation behaviors, dimensional accuracy, and material flow behaviors in the forming process. Through physical experiments and finite element simulations, it is revealed that the ultimate deformation load in the drawing-punching stage is smaller than that in the single deep drawing stage under microscale, but the results in the meso-scaled scenarios are opposite. In addition, the thickness variation is increased with grain size, but the variation of the normalized thickness variation does not show an obvious tendency with different size scales. In the bending area, the material flow is tangential to the thickness direction, leading to the formation of thinning area. In addition, the material flow is almost opposite to the punching direction in the punching area, avoiding the expanding deformation of the hole. Thus, the punching operation barely affects the dimensional accuracy including the thickness and hole diameter of the formed parts. Furthermore, the micro-scaled cups with finer grains have a better surface quality. These findings enhance the understanding of size effect in compound meso/microforming with the combined deep drawing and punching operations.
Faulting of rocks as a critical energy process
Authors: Reches Ze'ev , Wetzler Nadav
Published: January 2022

Faulting of rocks is a dominant earth process that governs small-scale fracturing, formation of tectonic plate boundaries, and earthquakes occurrence1–4. Since the 18th century, the mechanical settings for rock faulting were commonly analyzed with the Coulomb criterion5 that offers empirical, useful tools for scientific and engineering applications1,6–12. Here we revisit the processes of rock faulting by an alternative approach that incorporates elastic energy, strain-state, and three-dimensional deformation; these mechanical fundamentals are missing in Coulomb criterion. We propose that a stressed rock-body fails as two conditions are met: (1) The elastic energy generated by the loading system equals or exceeds a critical energy intensity that is required for the faulting process; (2) The internal strain of the stressed rock-body due to slip and dilation along the developing faults equals the strain-state created by the loading system to maintain physical continuity13,14. Our simulations reveal that meeting these energy and strain conditions requires an orthorhombic, polymodal fault geometry that is similar to natural and experimental fault systems15–20. The application of our formulation to hundreds of rock-mechanics experiments11,21–28 provides a new, comprehensive benchmark for rock-faulting.

Coronavirus disease (COVID-19) continues to be a major health concern leading to substantial mortality and morbidity across the world. Vaccination is effective in reducing the severity and associated mortality. Data pertaining to the duration of immunity, antibody waning and the optimal timing of booster dose administration is limited. In this cross-sectional study, we assessed the antibody levels in healthcare workers who were fully vaccinated after obtaining Institutional ethics committee approval and informed consent. Whole blood was collected and enumeration of S1/S2 neutralizing antibody levels was carried out using LIAISON SARS-COV-2 S1/S2 IgG assay. A total of 1636 individuals who were vaccinated with Covaxin or Covishield were included. Of these, 52% were males with a median age of 29 years. Diabetes and Hypertension was noted in 2.32% (38/1636) and 2.87% (47/1636) of the individuals. Spike neutralizing antibodies were below the detectable range (<15 AU/ml) in 6.0% (98/1636) of the individuals. Decline in neutralizing antibody was seen in 30% of the individuals above 40 years of age with comorbidities (diabetes and hypertension) after 6 months. These individuals may be prioritized for a booster dose at 6 months.
Bilateral Personalized Dialogue Generation with Contrastive Learning
Authors: Li Bin , Deng Hanjun
Published: January 2022

Generating personalized responses is one of the major challenges in natural human-robot interaction. Current researches in this field mainly focus on generating responses consistent with the robot’s pre-assigned persona, while ignoring the user’s persona. Such responses may be inappropriate or even offensive, which may lead to the bad user experience. Therefore, we propose a Bilateral Personalized Dialogue Generation (BPDG) method for dyadic conversation, which integrates user and robot personas into dialogue generation via designing a dynamic persona-aware fusion method. To bridge the gap between the learning objective function and evaluation metrics, the Conditional Mutual Information Maximum (CMIM) criterion is adopted with contrastive learning to select the proper response from the generated candidates. Moreover, a bilateral persona accuracy metric is designed to measure the degree of bilateral personalization. Experimental results demonstrate that, compared with several state-of-the-art methods, the final results of the proposed method are more personalized and consistent with bilateral personas in terms of both automatic and manual evaluations.
Wie verändert sich Medienerziehung im familienbiografischen Verlauf?
Authors: Potzel Katrin
Published: January 2022

Eine längerfristige Betrachtung elterlicher Medienerziehung findet noch kaum Beachtung. Ziel des vorliegenden Beitrags ist es Parental Mediation Strategien (aktive, restriktive und technische Mediation, ebenso wie Monitoring) empirisch über einen längeren Zeitraum zu untersuchen. Ein multiperspektivischer Ansatz ermöglicht einen Vergleich zwischen Eltern- und Jugendlichenperspektive. Eine besondere Rolle spielt zudem die Frage, wie konsequent sich Eltern in diesen Erziehungsstrategien verhalten und ob ebenfalls zeitliche Veränderungen beobachtbar sind. Die quantitative Panelstudie «Verläufe exzessiver Internetnutzung in Familien (VEIF)» liefert über vier Erhebungswellen im Abstand von etwa einem Jahr Daten aus Eltern- und Jugendlichensicht. So kann durch die Auswertung ein multiperspektivischer und längsschnittlicher Einblick gewonnen werden. Die Heranwachsenden waren zu Beginn zwischen 12 und 14 Jahren alt. Zwischen den Einschätzungen aus Jugendlichen- und Elternsicht zeigen sich mittlere bis starke Zusammenhänge, in den Mittelwerten allerdings auch signifikante Unterschiede. So werden die verschiedenen Strategien aus Erziehendenperspektive häufiger angewandt als aus Sicht der Jugendlichen. Längsschnittlich nehmen die Mittelwerte der eingesetzten Strategien aus beiden Sichtweisen signifikant ab. Anders gestaltet es sich in Bezug auf die inkonsistente Mediation: Eltern schätzen sich insgesamt konsequenter in ihrer Medienerziehung ein als die Heranwachsenden dies tun und es handelt sich aus beiden Perspektiven um einen zeitlich relativ stabilen Aspekt.

Published: January 2022

The main Russian and foreign manufacturers of low-voltage electrical devices - circuit breakers, fuses, magnetic starters, knife switches and packet switches are presented. The data of experiments for determining the resistance values of contact groups of low-voltage switching equipment are considered. The design features of the devices that determine the value of the resistances of the power circuits of low-voltage equipment are investigated and a classification is proposed depending on the design elements of the devices. A methodological approach and an algorithm for experiments and detailed analysis of the contact groups of devices are given. Experimental schemes for the study of contact groups are proposed. The data of the conducted experiments on the study of contact groups and the resistance values as a function of the flowing currents are shown. During the experiments it is revealed that the value of the resistance of the contacts changes depending on the value, type and time of exposure to current within +/-5 %. The laws that characterize the ratio of the resistance values of the structural components of devices (contact systems, thermal relay, coil of the maximum relay) have been revealed and defined. Empirical expressions and graphical dependences of the resistances of contacts and contact systems are obtained as a function of the magnitude of the rated currents of low-voltage contact equipment. The minimum sample size of the number of devices during experimental research is determined, sufficient to calculate the mathematical expectation of the resistances of the contact connections of the devices with a given accuracy. As a result of experimental studies, it is revealed that the resistance value of contacts and contact joints can increase during operation by 2-2.5 times. The established dependences of the change in contact resistance can be used to predict the technical state of electrical installations of intrashop low-voltage networks, to clarify the amount of electricity losses in shop networks up to 1 kV, and can also be used as an additional regulation for maintenance and scheduled preventive maintenance.

Published: January 2022

Mechanically deboned poultry meat is a valuable protein containing raw material widely used for the production of meat products. However, it does not have a high resistance to oxidation; therefore, various antioxidants including those of natural origin are used in its composition. The article provides information on the advisability of using rosemary extract and dihydroquercetin to stabilize lipids and interrupt hydrolytic and chain oxidative processes in mechanically deboned poultry meat. The permissible storage time for mechanically deboned poultry meat using the rosemary extract and dihydroquercetin in a chilled state is 96 hours. Research has been carried out on the oxidative processes of the fatty complex of mechanically deboned poultry meat during the refrigerated storage period. Antioxidants prevent the accumulation of peroxides: in the samples with their use, the peroxide number reaches critical values on 6-7 day of storage, without their use - on 3 day of storage. For all samples, a gradual increase in the acid number has been observed; however, for samples without antioxidants its values reach a critical level on the 4 day of storage, with the use of antioxidants - on the 7 day. The active formation of secondary oxidation products has begun from the second day of storage and reached the limit of permissible values in samples without antioxidants after 3 days of storage. In samples with antioxidants, the thiobarbituric number reaches a critical value on the 6 day. It has also been shown that the use of antioxidants contributes to the preservation of sensorial indicators (colour, odour) improving the quality of products. The efficiency of using the rosemary extract and dihydroquercetin as inhibitors of the oxidation of mechanically deboned poultry meat has been confirmed.

Authors: Shkolnikova M. N. , Abbazova V. N.
Published: January 2022

Pumpkin fruits ( Cucurbita spp.) have a number of advantages and high technological potential, thanks to almost universal cultivation in a wide range of agro-climatic conditions, the ability to long-term storage, the content of dietary fibers, pectin and other polysaccharides, carotenoids, polyphenolic substances, vitamins, which cause a wide range of physiological orientation. In the process of researching the composition of local cultivars of pumpkin and the world experience of using Cucurbita spp. in the composition of food products, the need to use this ingredient in beverage recipes has been substantiated. The content of dry substances in the pumpkin samples is from 8.18 % ("Gribovskaya") to 11.6 % ("Orange bush"). The maximum sugar content is distinguished by the varieties "Winter Sweet" (6.87 %) and "Orange Bush" (7.40 %). The content of BAS-antioxidants is (without visible difference depending on the growing region): carotenoids from 1.3 mg/100 g in "Gribovskaya" to 2.0 mg/100 g - "Orange bush"; ascorbic acid - 8.7 mg/100 g in "Rossiyanka" to 14.2 mg/100 g - "Orange bush". Today all parts of the pumpkin fruit are used: the bark is a raw material for the production of feed flour and a substrate for the cultivation of lactobacilli, the seeds are traditionally used to produce pumpkin oil and flour, the pulp of the fruit is a raw material for juice-containing products, purees, carotenoid-containing and polysaccharide extracts, pectin, concentrates of first and second dishes, snack products, pasta, bakery, confectionery and meat products, etc.
Application of the linear method of discriminant analysis of reflectance spectra in the near infrared region for the species identification of fish of the Salmonidae family
Authors: Novikov V. Yu. , Rysakova K. S. , Baryshnikov A. V.
Published: January 2022

It is well known that fish belonging to the Salmonidae family differ in their nutritional value. Anatomical and morphological features of different salmon species have a certain similarity; therefore, representatives of this family are most often falsified. Assortment falsification of products from fish of this family is usually carried out by replacing more valuable species with cheaper ones with a reduced nutritional value. Most often, counterfeiting of Atlantic salmon (salmon) by Far Eastern ones (chum salmon, pink salmon, chinook salmon, coho salmon) is found. Near infrared spectroscopy (NIR) is now increasingly used for identification and authentication of closely related organisms, in some cases being a rapid method replacing genetic analysis. We have obtained diffusion reflectance spectra of NIR radiation for three species of fish from the Northern Basin belonging to the salmon family. The best classification by fish species has been obtained by analyzing the NIR spectra of pre-dried fat-free muscle tissue samples. In case of wet samples, the observed differences are less significant, up to insignificant differences in individual values from neighboring clusters. The possibility of using the method of linear discriminant analysis of the NIR reflection spectra of muscle proteins for the species identification of fish has been shown.
A massive variable flavour number scheme for the Drell-Yan process
Authors: Gauld Rhorry
Published: January 2022

The prediction of differential cross-sections in hadron-hadron
scattering processes is typically performed in a scheme where the
heavy-flavour quarks (c, b, tc,b,t)
are treated either as massless or massive partons. In this work, a
method to describe the production of colour-singlet processes which
combines these two approaches is presented. The core idea is that the
contribution from power corrections involving the heavy-quark mass can
be numerically isolated from the rest of the massive computation.
These power corrections can then be combined with a massless computation
(where they are absent), enabling the construction of differential
cross-section predictions in a massive variable flavour number scheme.
As an example, the procedure is applied to the low-mass Drell-Yan
process within the LHCb fiducial region, where predictions for the
rapidity and transverse-momentum distributions of the lepton pair are
provided. To validate the procedure, it is shown how the
n_fnf-dependent
coefficient of a massless computation can be recovered from the massless
limit of the massive one. This feature is also used to differentially
extract the massless N^3LON3LO
coefficient of the Drell-Yan process in the gluon-fusion channel.

AVALIAÇÃO DA INTENSIDADE DO VENTO E SUA PARTICIPAÇÃO NA IDENTIFICAÇÃO DE ALVOS SUSPEITO DE PRESENÇA DE ÓLEO ATRAVÉS DE IMAGENS SATELITAIS ADQUIRIDAS POR RADARES DE ABERTURA SINTÉTICA
Authors: Moreira JULIANA Fernandes , Moreira Marcos Antônio Cruz , Villela Flávia Ribeiro , Pinto Augusto Eduardo Miranda
Published: January 2022

O presente artigo pretende demonstrar ao leitor a importância de se conhecer o parâmetro “vento” no sentido de sua intensidade para entender sua influência ou não em alvos suspeitos de presença de óleo na superfície do mar. A área abordada para estudo foi paralela à costa do Estado do Rio de Janeiro, onde ainda ocorre intensa exploração petrolífera e, por tanto, maior possibilidade de identificação de feições suspeitas de óleo. A utilização da tecnologia SAR – radar de abertura sintética – contribui consideravelmente para a coleta de dados, pois não possui interferência de cobertura de nuvens ou necessidade de insolação, como ocorrem com sensores óticos. A presença de recursos – embarcações e aeronaves - dotadas de equipamentos para identificação de presença de óleo na superfície do mar colaboram para a identificação e ratificação ou não do alvo suspeito ser efetivamente uma feição oleosa. Este trabalho se baseou na observação das formas – morfologias – dos alvos suspeitos que posteriormente foram confirmados como possíveis feições oleosas. A inovação do trabalho refere a análise da participação do parâmetro vento na interferência das morfologias apresentadas pelas feições.

METODOLOGIA PARA ANÁLISE DA CRITICIDADE SUBSIDIANDO A IMPLANTAÇÃO DA GESTÃO DO CONHECIMENTO CORPORATIVO
Authors: Sucena Marcelo Prado
Published: January 2022

Associando-se a análise da criticidade e modelos de gestão do conhecimento (GC) propostos na literatura, objetiva-se o desenvolvimento de uma metodologia genérica que represente as qualidades de todos os modelos estudados. O uso da criticidade se dá pela dificuldade das corporações em agregarem o total de recursos necessários para a implantação na empresa como um todo, possibilitando, assim, destacar as etapas mais críticas em setores menores e, com isso, otimizar a alocação dos recursos escassos. A metodologia genérica proposta contém nove etapas obtidas por pesquisa exploratória em seis modelos de GC. Para validar e testar a metodologia concebida desenvolveu-se um estudo de caso no setor de pós-venda de uma empresa do ramo automobilístico. Para tanto identificaram-se os recursos demandados em cada uma das nove etapas da metodologia genérica, calculando-se o Índice da Criticidade (IC) de cada uma, proporcionando o ranqueamento das etapas por grau de relevância. A coleta de dados para o estudo de caso foi realizada por entrevista semiestruturada com os gestores da empresa. Após a implantação da GC em um setor menor da empresa, pelo uso da metodologia proposta, é possível identificar as ações mais críticas, viabilizando a otimização dos recursos necessários. Além disso, por aplicação em escala reduzida na empresa, o planejamento para os demais setores é subsidiado pelo conhecimento adquirido, permitindo maior domínio do processo.

Published: January 2022

During the Covid-19 pandemic, the term work from home (WFH) has been introduced to refer to a work arrangement in which individual can complete their duties while they are at home. While most flexible work arrangements are a preference, work from home is mandatory. Therefore, the impact of WFH during the Covid-19 pandemic needs to be studied. The total respondent of this study is 337 employees, who are works at home during the pandemic. The results showed that the three main benefits employees might gain during WFH are flexibility, more time with family, and less travel time. On the other side, employees struggle to balance their personal and work life, access to websites or software, and limited devices and workspace. Most of the companies are not ready for the WFH scheme though some of them gave support to employees (e.g., quota subsidy). This research gave some essential suggestions for HR managers in designing remote work for the future.

Le polar « de banlieue » comme scène de déploiement du malaise social français le cas des romans « dyonisiens » de Rachid Santaki
Authors: Marcu Iona
Published: January 2022

The thriller tells daily explosive facts which take place, in most of the time, in a urban space. The authors describe, as the critics have observed, the most serious troubles in today’s society. Crimes, racism, trafficking, terrorism, theft, etc., all these crimes become the mark of an unbalanced world, a world in crisis. The “suburban”thriller, like suburban literature in general, circumscribes the scene in which the modern “misérables”clash. HLM, dangerous neighborhoods suffer because of urban disintegration, their inhabitants become victims of spatial and social dissolution. Rachid Santaki portrays in his novels young people who have lost their bearings, actors in a society where money is the only value, where violence is commonplace. In our contribution, we propose to see what are the different aspects of the French social malaise that Santaki denounces in the novels Flic ou Caillera(2013) and Les Princes du bitume(2017).

The object of the analysis carried out here is the Old Babylonian archive of Nūr-Šamaš, provenient from the Diyala region, formed by 116 loan contracts conceded by Nūr-Šamaš, and involving some 400 people as debtors and witnesses. Data obtained from the documents of the archive will be used to generate a graph modelling the relations of the attested persons. The graph will then be split into classes maximizing modularity, that is to say, into clusters optimally composed by personal identifications that statistically tend to connect more inside each cluster than with personal identifications of other clusters. Finally, this will be used to raise or lower the probability of stating that pairs of identifications of the type 'ZZZ, son of YYY' and 'YYY' may correspond respectively to a son and his father.

Biogas is an alternative to gaseous biofuels and is produced by the decomposition of biomass from substances such as animal waste, sewage sludge, and industrial effluents. Biogas is composed of methane, carbon dioxide, nitrogen, hydrogen, hydrogen sulfide, and oxygen. The anaerobic production of biogas can be made cheaper by designing a high throughput reactor and operating procedures. The parameters such as substrate type, particle size, temperature, pH, carbon/nitrogen (C/N) ratio, and inoculum concentration play a major role in the design of reactors to produce biogas. Multistage systems, batch, continuous one-stage systems, and continuous two-stage systems are the types of digesters used in the industry for biogas production. A comprehensive review of reactor design for biogas production is presented in the manuscript.

Los compromisos en políticas para la conservación y uso sostenible de la agrobiodiversidad son esenciales para un sistema agroalimentario sostenible. En este contexto, el objetivo de esta investigación se centró en analizar los compromisos en políticas públicas de México relacionados con el uso y conservación de la agrobiodiversidad. Para ello, se implementó la metodología propuesta en el Índice de Agrobiodiversidad, y para el análisis de los datos se usó minería de texto con un código semiautomatizado desarrollado en Python. Se analizaron tres sistemas: 1) alimentario, 2) agrícola y 3) de recursos genéticos. Los resultados del Índice de Compromisos en Agrobiodiversidad estuvieron en la media (48,6/100); los compromisos más altos se obtuvieron en el sistema de recursos genéticos (54/100) y los más bajos, en el sistema agrícola (38/100). La ausencia de compromisos sólidos se debe, entre otras cosas, a la temporalidad de las políticas y programas, así como a la atomización y poca comunicación entre instituciones dedicadas a objetivos similares. Se concluye que, ante las condiciones favorables de México relacionadas con la agrobiodiversidad, es necesario mejorar los compromisos en políticas públicas, ya que de eso depende en gran medida la resiliencia del sistema agroalimentario.

Published: January 2022

BACKGROUND

Surgical site infections (SSIs) are the most common nosocomial infection and occur in 16.3% of patients undergoing colorectal surgery at our institution (The Ottawa Hospital), the majority of which are identified after discharge from hospital. Patients who suspect having an SSI generally present to the emergency department or surgery clinic. Both options for in-person interaction are costly to the health care system and patients. A mobile app, how2trak, has proven to be beneficial for patients with complex wounds at our institution by facilitating at-home monitoring and virtual consultations.

OBJECTIVE

This study aims to assess the feasibility of a randomized controlled trial to assess if how2trak can improve patients’ experience and increase detection of SSIs after colorectal surgery while reducing patients’ risk of COVID-19 exposure.

METHODS

In this single-center prospective feasibility trial, eligible patients undergoing colorectal surgery will be randomized to either standard care or how2trak postoperative monitoring of their incision, symptoms, and ostomy function. Patient self-assessments will be monitored by a nurse specialized in wound and ostomy care who will follow-up with patients with a suspected SSI. The primary outcome is feasibility as measured by enrollment, randomization, app usability, data extraction, and resource capacity.

RESULTS

This study was approved by our institution’s ethics board on February 26, 2021, and received support from The Ottawa Hospital Innovation and Care Funding on November 12, 2021. Recruitment started June 3, 2021, and 29 were patients enrolled as of September 2021. We expect to publish results in spring 2022.

CONCLUSIONS

This study will determine the feasibility of using a mobile app to monitor patients’ wounds and detect SSIs after colorectal surgery. If feasible, we plan to assess if this mobile app facilitates SSI detection, enhances patient experience, and optimizes their care.

Factors Associated With the Experience of Cognitive Training Apps for the Prevention of Dementia: Cross-sectional Study Using an Extended Health Belief Model (Preprint)
Authors: Lee Jaegyeong , Lim Jung Min
Published: January 2022

BACKGROUND

The prevalence and economic burden of dementia are increasing dramatically. Using information communication technology to improve cognitive functions is proven to be effective and holds the potential to serve as a new and efficient method for the prevention of dementia.

OBJECTIVE

The aim of this study was to identify factors associated with the experience of mobile apps for cognitive training in middle-aged adults. We evaluated the relationships between the experience of cognitive training apps and structural variables using an extended health belief model.

METHODS

An online survey was conducted on South Korean participants aged 40 to 64 years (N=320). General characteristics and dementia knowledge were measured along with the health belief model constructs. Statistical analysis and logistic regression analysis were performed.

RESULTS

Higher dementia knowledge (odds ratio [OR] 1.164, P=.02), higher perceived benefit (OR 1.373, P<.001), female gender (OR 0.499, P=.04), and family history of dementia (OR 1.933, P=.04) were significantly associated with the experience of cognitive training apps for the prevention of dementia.

CONCLUSIONS

This study may serve as a theoretical basis for the development of intervention strategies to increase the use of cognitive training apps for the prevention of dementia.

UNSTRUCTURED

Methods to measure physical activity and sedentary behaviors typically quantify the amount of time devoted to these activities. Among patients with chronic diseases, these methods can provide interesting behavioral information, but generally do not capture detailed body motion and fine movement behaviors. Fine detection of motion may provide additional information about functional decline that is of clinical interest in chronic diseases. This perspective paper highlights the need for more developed and sophisticated tools to better identify and track the decomposition, structuration, and sequencing of the daily movements of humans. The primary goal is to provide a reliable and useful clinical diagnostic and predictive indicator of the stage and evolution of chronic diseases, in order to prevent related comorbidities and complications among patients.

This study was carried out to protect the continuity of productivity in morkaraman sheep raised in Turkey and determine their economic importance. Morkaraman sheep are concentrated in the Eastern Regions of the country. The province of Bingöl, where the study was conducted, is located in this region and has an important morkaraman population. The study was carried out between 2008-2018. Sixty-eight morkaraman sheep were used during the study period out of 317 lambing lambs. In the study, the total number of lambs born per sheep (TNLBS), the number of weaned lambs (NWL), the weights of the lambs weaned per sheep (WLWS) and the total weight of the lambs weaned in the first period (TWLWFP) were determined. In addition, Additive genetic variance, Error variance, Phenotypic variance, Heritability and Ratio of error variation were determined for these variables. As a result, the correlation between the examined variables was significant and positive, except for the relationship between TNLBS and TWLWFP. The relationship between these two variables was significant but negative. Significant changes were also observed in terms of genetic parameters. It was concluded that the economic aspects of the examined variables should not be ignored in terms of sustainability. Keywords: Sheep, morkaraman, sustainability, genotypic and phenotypic variance.

Citrus is one of the most important fruit crop in the world and is usually grown through grafting technique. Rootstock is one of the significant part in grafted plants and has crutial effect on production, including yield, fruit quality, tree size, tolerance to salts and diseases, and scion compatibility. Citrus is susceptible to several fungal pathogens causing incalculable losses to the crop. Among all soil-borne fungal pathogens, Phytophthora and Fusarium cause the most severe damage to the nursery or orchards plants. This research was planned to evaluate the effectiveness of fungicides as soil drenching and root dipping to control Phytophthora and Fusarium attacking citrus rootstock seedlings at the nursery stage. Different physiological and morphological parameters were studied in the infected plants and data were compared with that of control. The data were recorded and compared concerning rootstock seed and seeding response using standard measures and statistical analysis. The results showed that plants inoculated with Phytophthora and Fusarium root rot spp.when treated with Aliette and Ridomil Gold showed maximum root shoot ratio, fresh dry weight ratio, photosynthetic rate, stomatal conductance, water potential and transpiration rate as compared to untreated plants. The results also depicted that plants treated with Aliette and Ridomil Gold through soil drenching have maximum root shoot ratio, fresh dry weight ratio, photosynthetic rate, stomatal conductance and transpiration rate as compared to root dipped plants. Keywords: Fungal diseases, pathogens, root rot, nursery plants.
