Published: January 2021

Inheritance of Resistance to PStV in Transgenic Peanuts Containing cp PStV Gene. We have obtained transgenic peanut lines containing coat protein gene of PStV. To get maximal use of the transgenic character in a breeding program, it is necessary that the transgene is also stably inherited and expressed.  This experiment was conducted from June 2002 – January 2005 at Plant Molecular Biology Laboratory, Bogor Agricultural University, and Queensland Agricultural Biotechnology Center, The University of Queensland, Australia. The research aimed (1) to test whether PStV cp transgene was functional in progenies derived from crosses between transgenic peaanut plants containing PStV cp gene and non-transgenic ones and (2) to determine pattern of inheritance of resistance to PStV as a result of PStV  cp gene action. Several crosses were made between trangenic peanut cv.Gajah resistant to PStV (T4 generation) and non-transgenic peanut line WS susceptible to PStV. The F1 and F2 populations were mechanically inoculated with PStV two weeks after planting. The experiment showed that all plants in the F1 population were less susceptible to PStV, suggesting that the transgene was partially dominant.  Phenotipic segregation in F2 population was not Mendelian with the appearance of quick and slow recovery plants and the number of resistant plants being more than expected. However, the proportion of transgenic and non-transgenic plants followed 3:1 ratio, which was Mendelian.

This research was conducted in the Sub District of Samigaluh, Kulon Progo and Laboratory of Bacteriology, Plant Protection Department, Faculty of Agriculture, Gadjah Mada University, Yogyakarta December 2002 to June 2003. The aim of this research was to investigate relationship between arrival frequency of Erionota thrax to the banana’s flower and disease incidence of  Banana Bacterial Wilt in the three diffrent land uses (wet rice field, dry field and house yard). A survey method was done in this research. Stratified purpossive sampling was performed to collect the data. Strata used were wet rice field, dry field and house yard. Observation of the arrival frequency of E. thrax was done to the flowering banana. Data that collected in this study were disease incidence of Banana Bacterial Wilt and arrival frequency of E. thrax to the banana’s flower. The data was analized with Correlation test using SPSS 11.5 for windows with 5% of significant level. The results showed that the arrival frequency of imago E. thrax to the banana’s flower per one flowering seasons (5 days) were 17.65 imago (wet rice field), 15,65 imago (dry field) and 11 imago (house yard). Meanwhile, the disease insidence of Banana Bacterial wilt in the three different land uses were 5.41% (wet rice field), 3.81% (dry field) and 7.10% (house yard). Correlation analysis showed that there was no relationship between arrival frequency of E. thrax to the banana’s flower and the disease insidence of Banana Bacterial Wilt in the three different land uses. Its means that the arrival frequency of E. thrax to the banana’s flower did not influence the disease incidence of banana bacterial wilt in those areas.

Eficiency of parasitization on larval host, Spodoptera litura (F.), by an endoparasitoid Snellenius (=Microplitis)manilae Ashmead in the laboratory. The armyworm, Spodoptera litura (F.) is the host of an endoparasitoid Snelleniusmanilae Ashmead. This research described the effect of host larval stage preference, the number of host exposure and theage of parasitoid on the resulting parasitization. Each group of the first to the fifth of host instar (30 larvae) was exposed for3 hours to a pair of four-day old parasitoids in a trial cage. The same exposures were conducted without choices by placingeach instar group within each trial cage. The parasitoid survival was observed by maintaining the parasitized larvae untiladult emergence. Each group of 10, 20, 30 and 40 of the second instar larvae were exposed for 12 hours/day to a matedfemale parasitoid. This experiment was conducted from the first day old parasitoid until the females died. The percentageof parasitization, superparasitization, oviposition and the fecundity of adults were recorded. Each group of thirty secondinstar larvae was exposed separately to a mated female parasitoid of 1 to 9 days old. The survival of progeny was recorded.All treatments in this observation were repeated 10 times. S. manilae preferred to lay eggs on the third (41.7%) followed bythe second (22.3%) instar larvae of S. litura. The lowest percentages of superparasitization obtained from the first and thesecond instar larvae were between 11 and 15% and the highest percentage of superparasitization obtained from the fourthinstar larvae was 52%. The highest survival of parasitoid was found on the exposure of the second instar larvae whichreached 16%. The highest efficiency of parasitism (80.9%) was found on the twenty of the second instar larval exposuredensity which produced 59% of optimal parasitization level, the average rate of egg laid by females was 25 eggs/day, andthe fecundity was 185 eggs/female. Female parasitoids of 1-7 days old gave the same opportunity to produce progenysurvival which was in the range of 10.3-25.7%.

ANALISIS KADAR AFLATOKSIN JAGUNG LOKAL TIMOR PADA PERLAKUAN LAMA PENGERINGAN DENGAN UDARA ALAMIAH
Authors: Nino Jefrianus , Neonbeni Eduardus Y
Published: January 2021

Jagung merupakan salah satu komoditas sumber karbohidrat yang mempunyai masalah pada saat penyimpanan. Masalah yang sering ditemukan yakni kontaminasi aflatoksin yang cukup tinggi. Kontaminasi aflatoksin berupa serangan mikroorganisme, dan jamur. Jagung memiliki kandungan air yang cukup tinggi setelah dipanen. Kontaminasi aflatoksin umumnya disebabkan oleh tingginya kandungan air pada jagung. Hal ini diakibatkan oleh proses penanganan pascapanen yang kurang cepat setelah jagung dipanen. Salah satu cara pencegahan kontaminasi aflatoksin yakni pengeringan. Pengeringan merupakan sebuah proses difusi air dari bahan ke atmosfir untuk mencapai kadar air standar penyimpanan. Dalam proses pengeringan lama waktu pengeringan sangat berpengaruh terhadap banyak jumlah air yang akan diuapkan. Semakin lama waktu pengeringan maka jumlah air yang diuapkan akan semakin lebih banyak sehingga peluang terjadinya kontaminasi aflatoksin semakin kecil. Salah satu metode pengeringan yang digunakan yakni pengeringan dengan memanfaatkan udara alamiah. Pengeringan dengan menggunakan udara alamiah merupakan salah satu alternatif penghematan energi termal. Potensi dari pengeringan alamiah yakni memanfaatkan udara lingkungan yang tersedia gratis, bersifat ramah lingkungan dan murah. Kelemahan dari metode pengeringan tersebut yakni terjadinya fluktuasi suhu akibat cuaca yang tidak menentu. Kondisi tersebut dapat menyebabkan terjadinya kontaminasi aflatoksin pada jagung. Penelitian ini bertujuan untuk mengetahui kadar aflatoksin jagung dari variabel lama waktu pengeringan pada pengeringan menggunakan udara alamiah. Metode penelitian mencakup pengujian pengeringan di lapangan dan dilanjutkan analisis perubahan kadar air, dan analisis kadar aflalatoksin di laboratorium. Berdasarkan hasil penelitian tercatat bahwa dengan kadar air awal 25,93% bb, suhu lingkungan rata-rata 36,77°C, kelembaban lingkungan rata-rata 76,86% mampu menurunkan kadar hingga kadar air akhir 15,12% bb. Hasil analisis aflatoksin variabel lama pengeringan yang digunakan tidak terjadi kontaminasi aflatoksin.

Training Mathematics Teachers for Developing Critical Thinking Skills in VIGrade Pupils
Authors: BĂDESCU Ovidiu , STAN Cristian
Published: January 2021

Abstract: Critical thinking and creativity along with problem-solving skills have become basic competencies in an increasingly complex and technological world, in which an individual needs to be able to process information in a critical way, find alternative solutions, analyse complex problems, and formulate innovative solutions. As teachers, we train the children for occupations that have not been invented yet – an aspect that thus becomes clear is that it is no longer sufficient for the young students to perfectly execute given tasks, but they need to be able to solve new problems. To achieve this, they need to be able to consider the problem from multiple angles, to weight alternatives, to look critically at what needs to be solved, and to make well-thought and well-argued decisions. With this perspective in mind, developing such skills in pupils should be an essential goal for the teachers. Yet, unfortunately, training teachers for developing critical thinking skills in pupils comes short, in the Romanian educational system. This article presents the results of a traning course whose goal was to prepare mathematics schoolteachers to teach mathematics based on questioning and discovery, to help develop pupils’ crticical thinking skills. Analyzing the short- and long-term impact of our training course confirms the results obtained in OECD (2019) studies, namely that once teachers have been qualified to work in this way, they become more open to acting differently to stimulate the developing of critical thinking and creative skills in pupils.

Abstract: The aim of this study is to determine the relationship between academic boredom with academic self-efficacy and mathematics anxiety of 280 middle school students. Both the descriptive and correlational survey models were used in line with the sub-problems of the study. In this study, Level of Boredom Scale, Sources of Middle School Mathematics Self-Efficacy Scale, and Revised Fennema-Sherman Mathematics Anxiety Scale-Elementary were used as data collection tools. It was found that 5th, 6th, 7th and 8th grade students had middle level academic boredom in mathematics classes regardless of their grade levels. It was concluded that the self-efficacy perceptions related to performance accomplishments, vicarious experience and verbal persuasion were high in each class level, whereas the self-efficacy perceptions of emotional arousal were low. In general, it was relevealed that the anxiety of students in mathematics lessons was low while 8th grade students' mathematics anxiety was higher than the 5th, 6th and 7th grade students. Moreover, findings also revealed that there was a low positive relationship between students' boredom in mathematics lessons and vicarious experience which is used in lessons. No relation was found between the boredom and mathematics anxiety of students.
DITTRICHIA GRAVEOLENS (ASTERACEAE) – A NEW ALIEN PLANT SPECIES FOR ROMANIA
Authors: SZATMARI Paul-Marian , HURDU Bogdan-Iuliu
Published: January 2021

Dittrichia graveolens (L.) W. Greuter, an invasive plant species of Mediterranean origin, is recorded for the first time in Romania. We found the species in October 2020 in two separate locations along the main highway that connects Brașov and Sibiu cities, in Southern Transylvania, central Romania. We present here the first data concerning the species occurrence in the investigated area, its observed habitat, local distribution and accompanying species. We presume that the main vector for the introduction and dispersal of this species in Romania is the high traffic density along the major roads. Dittrichia graveolens has proven its invasive potential in other regions of Europe and North America of similar temperature and precipitation regimes under an overall temperate climate. Consequently, taking into account its fast dispersal, especially in the more favourable habitats for its establishment that exist along the major roads from the lower altitudes and the riparian communities from the western, southern and eastern parts of Romania, we conclude that close monitoring of the species occurrence should be undertaken in order to better assess its full invasive potential in our country and to reduce the risk of impact on natural plant communities.

Una suerte de calma hechizada. Praxis de extrañamiento y trascendencia poética (Paseando por el Rastro con Gómez de la Serna)
Authors: Moreno Márquez César
Published: January 2021

El presente artículo se propone indagar en la praxis de extrañamiento que lleva acabo Gómez de la Serna en El Rastro (1914), praxis que será esencial de cara a comprender uno de los vectores fundamentales de la (ulterior) objetología surrealista. Dicha praxis comprende al menos ocho prácticas o posibilidades de deshacer que afectan al Límite (que discrimina y jerarquiza), al Futuro (ingenuo y dictatorial), a la familiaridad hogareña burguesa (que encarcela y amodorra), a la funcionalidad utilitaria (que banaliza), a la idealidad falsa (de los prestigios de la ciudad), a la propiedad (de nuestras cosas), a uno mismo (praxis de desasimiento), y al propio texto. Estas prácticas configuran un extrañamiento masivo, aunque sereno, con una clara proyección de trascendencia poética, existencial y metafísica

Entrepreneurship, from a few years ago, is considered as a determining factor of the economic performances in the countries sending development. Its structural role and the dynamism it impels in all economies is no more established. For this reason, in this paper we proposed to use a methodology based on entrepreneurial and information systems for management master students in Ibn Zohr University Morocco. This methodology permit to facilitate to create the proper project in different disciplinary fields.Nowadays, all agents insist on the development of entrepreneurship as well as the creation of enterprises as a catalyst for global economic growth. In this spirit, the development of the culture of business creation among students is a key factor to emerge new generations of entrepreneurs driven by entrepreneurial passion for entrepreneurship and motivated by the culture of innovation. entrepreneurship mentality.Indeed, academic training is one of the determinants that significantly affects the spirit of entrepreneurship among students and recent graduates, and therefore on economic development in general. two questions arise, how do Ibn Zohr University master’s students perceive entrepreneurship, and does academic training and entrepreneurship awareness impact the intention and desirability of entrepreneurship in his students? To answer these questions, we developed a quantitative practical study based on a survey administered and collected from the young master’s students of Ibn Zohr University in Agadir. Thus, the results of this study show that the intention, desirability and feasibility of young students with respect to entrepreneurship are associated with personal, professional, cultural and contextual characteristics. And they differ between the different institutions of Ibn Zohr University.

The use of a communication network in the closed loop control systems has many advantages such as remotely controlling equipment, low cost, easy to maintenance, efficient information transmission, etc. However, the Networked Control System (NCS) has many drawbacks, such as network-induce end-to-end time delay and packet loss, which lead to significant degradation in controller performance and may result in instability. Aiming at solving performance degradation in NCS, this paper propose to take the advantages and strength of the conventional Proportional-Integral-Derivative (PID), Fuzzy Logic (FL), and Gain Scheduling (GS) fundamentals to design a Fuzzy-PID like-Gain Scheduling (F-PID-GS) control technique, which has been proved to be effective in obtaining better performance. The True Time toolbox is used to establish the simulation model of the NCS. Ethernet as a communication network is simulated for different load conditions and random packet loss. The design approach is tested on a second order stepper motor. The results obtained show the effectiveness of the proposed approach in improving the overall system performance.
Implementable Self-Learning PID Controller Using Least Mean Square Adaptive Algorithm
Authors: Sami Hasan  , Aya Moufak Ismael
Published: January 2021

More than 95% of the industrial controllers in use today are PID or modified PID controllers. However, the PID is manually tuning to be responsive so that the Process Variable is rapidly and steady moved to track the set point with minimize overshoot and stable output. The paper presents generic teal-time PID controller architecture. The developed architecture is based on the adaption of each of the three controller parameters (PID) to be self- learning using individual least mean square algorithm (LMS). The adaptive PID is verified and compared with the classical PID. The rapid realization of the adaptive PID architecture allows the readily fabrication into a hardware version either ASIC or reconfigurable.

The article presents the actual knowledge of chemistry and pharmacological activity of fumitory (Fumaria officinalis L.). The genus Fumaria (latin fumus – smoke) includes about 55 species of annual plants, occuring in Asia, North Africa, Europe. In Poland, F. officinalis overgrows fields, wastelands, the roadsides, gardens. Fumariae herba contains numerous isoquinoline and indenobenzazepine alkaloids, flavonoids (derivatives of quercetin and kaempferol), organic acids and mineral salts. The results of the research, including clinical trials, have shown that compounds contained in fumitory have a strong diastolic effect on the smooth muscles of the intestines, biliary tract, urinary tract and blood vessels, as well as increase or decrease the production of bile, according to the body’s needs (amphocholeretic action). The extracts of Fumariae herba are used to relieve the symptoms of indigestion (feeling of fullness and bloating).

Introduction. Common basil (Ocimum basilicum L.) is one of the most valued and widely used spice plants. The highly valued raw material requires properly prepared soil, mainly rich in nutritions. Traditional use of single-component fertilizers, such as nitrochalk, superphosphate and potassium salt does not guarantee its uniform sowing in the field. The multi-component fertilizer is a safer option. Aim. The investigation was performer in order to assess the impact of multi-component fertilizers on the size and some quality features of the yield of common basil in experimental nutrient works. Material and methods. Three experimental nutrient works were performed in 2013-2015 in the cold greenhouse of the Institute of Natural Fibres and Medicinal Plants (Plewiska, Poland) with use of common basil cvar. ”Wala” seedlings. Fresh and dry mass of herb (after drying in a thermal dryer to a constant weight) and the content of essential oil (by steam distillation in the Deryng apparatus). The outcomes were statistically analyzed (analysis of variance). Results. The increase in dry matter of herb was noted with use of Salmag S fertilizer, as compared to the combination with traditional one-component fertilizers, regardless of the level of fertilization. The content of essential oil in the raw material did not depend on the type and size of the fertilizer used. Conclusions. The research results justify the use of specific multicomponent fertilizers in the cultivation of basil and will be implemented into practice (training, consulting) as a part of the introduction of rational fertilization principles.

The pyrrolizidine alkaloids are commonly found in many plants. They are present in well-known medicinal plants as: comfrey (Symphytum officinale L.), common butterbur (Petasites hybridus L.), coltsfoot (Tussilago farfara L.) or borage (Borago officinalis L.). Some of this plants are not used in phytotherapy or are used with big restrictions. We must pay attention that several human food products can be a source for pyrrolizidine alkaloids ingestion as a consequence of pollution of farmlands by plants originated from families: Senecio, Echium, Heliotropium, Crotalaria, Boraginaceae and Eupatorium. When harvesting, it may lead to contamination of food grains and feed for livestock. In consequence, pyrrolizidine alkaloids are detected in food products just like: baker’s goods, cakes, milk, cheese, yoghurts or meet.
