Epichloë Endophyte

For 30 years, forage ryegrass breeding has known that the germplasm may contain a maternally inherited symbiotic Epichloë endophyte. These endophytes produce a suite of secondary alkaloid compounds, dependent upon strain. Many produce ergot and other alkaloids, which are associated with both insect deterrence and livestock health issues. The levels of alkaloids and other endophyte characteristics are influenced by strain, host germplasm, and environmental conditions. Some strains in the right host germplasm can confer an advantage over biotic and abiotic stressors, thus acting as a maternally inherited desirable ‘trait’. Through seed production, these mutualistic endophytes do not transmit into 100% of the crop seed and are less vigorous than the grass seed itself. This causes stability and longevity issues for seed production and storage should the ‘trait’ be desired in the germplasm. This makes understanding the precise nature of the relationship vitally important to the plant breeder. These Epichloë endophytes cannot be ‘bred’ in the conventional sense, as they are asexual. Instead, the breeder may modulate endophyte characteristics through selection of host germplasm, a sort of breeding by proxy. This article explores, from a forage seed company perspective, the issues that endophyte characteristics and breeding them by proxy have on ryegrass breeding, and outlines the methods used to assess the ‘trait’, and the application of these through the breeding, production, and deployment processes. Finally, this article investigates opportunities for enhancing the utilisation of alkaloid-producing endophytes within pastures, with a focus on balancing alkaloid levels to further enhance pest deterrence and improving livestock outcomes.

Elegir el futuro profesional nunca ha sido tarea fácil para los jóvenes bachilleres. Si a esto le añadimos la inestabilidad del mercado laboral y el cambio de modelo productivo generado por el impacto de las TIC y la globalización, la decisión es mucho más compleja. Lo cierto es que, dentro de unos años, cuando los actuales jóvenes bachilleres inicien su trayectoria laboral en una sociedad tecnológicamente más avanzada, tendrán que elegir profesiones que aún no existen. En parte, esas nuevas profesiones se formarán de la convergencia de importantes áreas de especialización en ciencias y tecnología como la microinformática, la biotecnología y la física cuántica, además del resultado de la transformación digital que está operando transversalmente en otros muchos sectores de actividad como el de la educación, la salud, el transporte, la logística o el financiero. Este artículo forma parte del estudio empírico de mi tesis doctoral sobre el déficit de talento femenino en las ingenierías tecnológicas. En este texto trato de explicar la relación entre la digitalización de la economía, el empleo y la educación con la elección de estudios universitarios y el papel que están haciendo la Unión Europea, el Gobierno de España y otros organismos y asociaciones para motivar a las mujeres a estudiar ingenierías tecnológicas o trabajar en el sector TIC.Choosing the right career has never been an easy task for young high school graduates. If we add to this doubt the instability of the labour market, the productive model changed by the impact of the ITC and globalization, the final decision must be more complex. The truth is that, in a short time, when current students start working in a digital society, they will have to choose careers that do not exist yet. In part, the new careers will be formed by the convergence of three important specialization areas: microcomputation, biotechnology and quantum physics, as well as the result of the digital transformation that is being carried out transversally in many other sectors of activity such as education, health, transportation, logistics, business, etc. This article is an extract from an empirical study which I am developing in my doctoral thesis on the lack of female talent in the ICT engineering. In this text, I try to explain the relationship among the digitalization of the economy, the employment and education, and the selection of university studies and the role that the Spanish Government, the EU and other institutions and academic associations are playing in this area in order to encourage women to study ICT engineering or even to work in the ICT sector.

This paper reviews recent works on the application of nanofibers and nanoparticle reinforcements to enhance the interlaminar fracture toughness, to reduce the impact induced damage and to improve the compression after impact performance of fiber reinforced composites with brittle thermosetting resins. The nanofibers have been mainly used as mats embedded between plies of laminated composites, whereas the nanoparticles have been used in 0D, 1D, 2D, and 3D dimensional patterns to reinforce the matrix and consequently the composite. The reinforcement mechanisms are presented, and a comparison is done between the different papers in the literature. This review shows that in order to have an efficient reinforcement effect, careful consideration is required in the manufacturing, materials selection and reinforcement content and percentage. The selection of the right parameters can provide a tough and impact resistant composite with cost effective reinforcements.

The Covid-19 case has had a huge influence on all aspects of human life, starting from health, economy, sosial, law, and many more. The COVID-19 pandemic has caused various frictions between various interests, one of which is a clash between individual interests and community interests. One of the obvious things about this problem is regarding the impact of COVID-19 in the field of sociology, especially the relationship between individuals, especially the issue of community stigmatization regarding infectious diseases, the dilemma between the privacy rights of the identity of COVID-19 patients and the disclosure of publik data on COVID-19 patients with various risks will injure and cause multiple material and immaterial losses. On the other hand, Covid-19 also raises various sosial-psychological problems and legal problems that still do not regulate all aspects of human life. This paper describes the sociological elements of COVID-19, the right to privacy, publik information disclosure, and the sosial-psychological impact of COVID-19, along with a juridical review of the right to privacy and publik disclosure of information regarding the transparency of COVID-19.

Abstrak: Dalam Undang-Undang Nomor 23 Tahun 2006 tentang Administrasi Kependudukan adanya Pasal yang mengatur tentang perkawinan beda agama, dalam Pasal 35 huruf (a) yang menyatakan bahwa perkawinan yang ditetapkan oleh pengadilan. Namun dalam Undang-Undang tersebut tidak diatur secara jelas, sehingga memberi peluang timbulnya dampak negatif. Namun yang diakui di Indonesia jika pasangan suami istri yang berbeda agama harus memeluk agama yang sama di salah satu pasangan dengan maksud mereka harus pindah agama baik memeluk agama istri maupun suami. Dengan adanya berbagai kemudharatan yang timbul, maka hal itu tidak sesuai dengan hukum Islam. Oleh karena itu, penulis ingin mengetahui dampak perkawinan beda agama yang diatur dalam Undang-Undang Nomor 23 Tahun 2006 tentang administrasi  kependudukan dan tinjuan hukum Islam terhadap perkawinan beda agama dalam Undang-Undang Nomor 23 tahun 2006. Dalam penelitian ini, metode penelitian yang digunakan adalah Kualitatif. Berdasarkan dari hasil penelitian, dampak dari perkawinan beda agama yaitu dampak terhadap rumah tangga yang tidak harmonis menimbulkan kegelisahan, dan sulitnya berkomunikasi. Dampak terhadap anak yang membuat hubungan antara keluarga yaitu anak dan orang tua menjadi kacau dan tidak utuh karena mengetahui kedua orang tuanya berbeda keyakinan. Dampak terhadap harta warisan yang mengakibatkan anak yang lahir dari perkawinan beda agama tidak mempunyai hak untuk mendapatkan harta warisan apabila tidak seagama dengan pewaris yang dalam hal ini pewaris beragama Islam. Adapun tinjauan hukum Islam menyatakan bahwa perkawinan beda agama itu tidak sah, karena menurut fatwa MUI Nomor:4/MUNASVII/MUI/8/2005 menetapkan bahwa nikah beda agama hukumnya haram yang diperkuat dengan firmannya dalam surat al-mumtahanah ayat 10 dan al-baqarah ayat 221.Abstract: in Law No. 23 of 2006 on the administration of the population of the article governing the marriage of different religions, in article 35 letter (a) stating that the marriage is established by the court. But the law is not regulated, so it allows causing negative impacts. But it is recognized in Indonesia if different couples of religion must embrace the same religion in one partner with the intention they have to move religion both embrace the religion of the wife and husband. With the various blessings that arise, it is not under Islamic law. Therefore, the author wants to know the impact of the marriage of different religions organized in law Number 23 the year 2006 about the administration of population and the Islamic law to the marriage of different religions in the law Number 23 the year 2006. In this study, the research method used was qualitative. Based on the results of the study, the impact of the marriage of different religions is the impact on the unharmonious households raises anxiety, and difficulty communicating. The impact on the child who makes the relationship between the family is the child and the parent becomes chaotic and not intact because knowing both parents are different beliefs. The impact on the inheritance that resulted in children born from the marriage of different religions does not have the right to obtain inheritance if not as religious as the heir, in this case, Muslim heirs. The review of Islamic law states that the marriage of different religions is not valid, because according to fatwa MUI number: 4/MUNASVII/MUI/8/2005 stipulates that the marriage of different religious religion is haram strengthened by his word in Sura al-Mumtahanah verse 10 and al-Baqarah verses 221.

Epidemics and pandemics are difficult periods for the affected community, specifically in the proliferation of mental health issues. In such adverse times, factors of psychological vulnerability such as propensity to worry and low emotional stability might have a detrimental effect on the mental health of the individuals. To investigate the impact of such factors on mental health, this study examined the impacts of propensity to worry and fear of COVID-19 on anxiety depending on the individuals’ levels of emotional stability. As a means of such investigation, this study was conducted based on quantitative data, and the research sample was selected using a convenient sampling method. Participants included 304 university students (71.6% were women and 28.4% were men; MAge = 22.37 ± 3.04) and responded to the Penn State Worry Questionnaire, Fear of COVID-19 Scale, Symptom Checklist-90 Revised, and 10-Item Personality Inventory. The moderated mediation analysis using PROCESS macro (Model 14) was performed to examine the study hypotheses. Results revealed that propensity to worry was associated with anxiety symptoms. Fear of COVID-19 mediated this link and emotional stability moderated the relationship between propensity to worry and anxiety. The findings showed that trait worry, trait emotional stability, and fear of COVID-19 are determinants of anxiety symptoms, suggesting that such factors are important in understanding these issues.

Shepperd et al. (2014) find that the reported performance of a defect prediction model shares a strong relationship with the group of researchers who construct the models. In this paper, we perform an alternative investigation of Shepperd et al. (2014)’s data. We observe that (a) researcher group shares a strong association with the dataset and metric families that are used to build a model; (b) the strong association among the explanatory variables introduces a large amount of interference when interpreting the impact of the researcher group on model performance; and (c) after mitigating the interference, we find that the researcher group has a smaller impact than the metric family. These observations lead us to conclude that the relationship between the researcher group and the performance of a defect prediction model may have more to do with the tendency of researchers to reuse experimental components (e.g., datasets and metrics). We recommend that researchers experiment with a broader selection of datasets and metrics to combat potential bias in their results.

When a decision-making process relies on the information provided by a measurement or simulation result, the right decision demands a good quality result, in other words, a low uncertainty result. In order to establish public policies for environmental noise control, it is essential to identify the impact of each type of noise pollution (e.g. road, aircraft and rail transportation noise) on the population affected. One of the noise impact metrics that can be used is the number of highly noise annoyed people in a region whose estimated value is obtained from the corresponding exposure-response function and noise and population density maps. However, an estimated value of the noise impact metric with high uncertainty makes it difficult to realize the actual severity of the problem and its priority in relation to other public health issues. In this work, a Monte Carlo simulation method is used to assess the uncertainty of a noise impact metric result, namely the number of people highly disturbed by road noise in a city. This article also presents a sensitivity analysis of uncertainty sources that allows quantification of the main uncertainty components, which supports improvements in noise impact metric results.

The focus of this chapter is on the environmental impact consequences of endemic livestock health challenges that lead to deterioration in animal health, and on the potential impacts arising from their mitigations. The first part of the chapter concentrates on the potential of animal health to affect the environmental impact of livestock systems. Subsequently, it reviews the literature to date which has quantified the impact of health challenges for the environmental impacts of livestock systems. The potential of successful health interventions to mitigate negative environmental impacts represents a point of synergy between concerns around environmental sustainability and animal welfare, both of which represent 'hot topics' in the discourse surrounding the livestock industry and its sustainability. The challenges associated with modelling health interventions and their potential to mitigate environmental impacts constitute the last section in the chapter.

The impact of insecticide resistance is well documented. It includes the toxic effects of pesticides on the environment and the cost of the increased amounts of insecticides required to effectively control resistant insects. Resistance evolves by the selection of genes that confer tolerance to insecticides. Several resistance genes have been identified and cloned in Drosophila, including genes for mutant target molecules and genes that increase insecticide degradation. Drosophila is a useful system to understand the evolution of quantitative traits in general as well as the population genetics of insecticide resistance. Through it, we may hope to understand the relationship between discrete genetic change and continuously varying characters. In addition, molecular genetic techniques developed using Drosophila can eventually be transferred to other insects in order to help control pest populations.Key words: insecticide resistance, evolution of tolerance, selection of resistant genes, molecular genetics, Drosophila.

Managers who are responsible for the management of companies are faced with two important decisions - investment and funding. The right investment decisions and choice of funding sources are important because they affect the company's financial performance. The selection of the types of assets to be invested and the right types of financing sources result in optimal returns for the company. It reflects good company performance and future prospects. In addition, optimal return is a good sign for investors. Companies that perform well experience increase in the value of their firm. This study examined the effect of investment decisions and the selection of appropriate sources of funds on the performance of the company and the consequent impact on the firm value. The study was conducted in two parts. The first part examined the effect of investment decisions on long-term assets with long-term funding on the rate of return and firm value. The second part examined the effect of investment decisions on the company's short-term assets and funding for financial performance and firm value. The case study used in this research is a consumer goods sub-sector company listed on the Indonesia Stock Exchange in the period 2010 to 2017. Path analysis is the data analysis tools that was used. The results of data analysis showed that the asset structure has an effect on financial performance and firm value. The capital structure affects the financial performance but does not affect the firm value of the company. Financial performance was measured by ROI.
