A Hybrid Approach to Improve Energy Dissipation in Stilling Basin
Authors: Kapure P.V. , Nangare S. P. , Gaikwad T. R. , Narke M. S. , Huge P. A.
Published: April 2022

Abstract: This study contains a hydraulic prototype model and experiments that will be conducted to generalize and prove the hydraulic design of a new type of stilling basin that controls discharge with a hollow-jet valve. The stilling basin is usually considered to be the most efficient hydraulic structure for dissipating flow energy. The size and shape of the stilling basin affect the formation of flow patterns, which can affect the overall hydraulic performance of the system. An ogee spillway's is important for dissipating excess water's specific energy. The kinetic energy generated by the release of water from the top to the toe of the spillway is considerable. This will cause scour and erosion on the downstream face of the spillway. The above problems are going to be solve by developing a workable physical model for an ogee spillway that considers the combined impacts of steps, roller buckets and USBR Stilling basin. Keywords: Ogee Spillway, Steps, Roller Bucket, Stilling Basin, Energy Dissipation.
Constitutionality of monitoring and evaluation of regional regulation drafts and regional regulations by Regional Representative Council
Authors: Wido Haruni Catur
Published: April 2022

This research examines the constitutionality and legal implications of the DPD's new powers and duties in monitoring and evaluating regional regulation drafts in terms of the function of the DPD. The research method uses a normative approach and qualitative descriptive analysis. The results of the research show that the addition of the authority and duties of the DPD to carry out monitoring and evaluation constitutionally has no legal basis so the arrangement can be deemed unconstitutional. On the other hand, if the new authority arrangement for the DPD is seen as not contrary to the Constitution, then this will set a precedent so that the addition of the authority of the Regional Representatives Council is not only within the purview of supervision but it can also be carried out within that of legislation, without making changes to the constitution and simply through the Law. In terms of the legal implications of the authority and a new task of DPD to set the scope of monitoring and evaluation, monitoring and evaluation models, and overlapping authorities to conduct monitoring and evaluation with those in the Central Government, DPD cannot give any follow-up to monitoring results. Thus, restructuring the tasks and authority of the DPD in the constitution and the statute is a must.
Environment-assisted strong coupling regime
Authors: Sergeev Timofey T. , Vovcenko Ivan V. , Zyablovsky Alexander A. , Andrianov Evgeny S.
Published: April 2022

Strong coupling regime takes place in open hybrid systems consisting of two or more physical subsystems when the coupling strength between subsystems exceeds the relaxation rate. The relaxation arises due to the interaction of the system with environment. For this reason, it is usually believed that the enhancement of the interaction with environment inevitably leads to a transition of the system from the strong to weak coupling regime. In this paper, we refute this common opinion. We demonstrate the interaction of the coupled system with environment induces an additional coupling between the subsystems that contribute to retention the system in the strong coupling regime. We show that the environmental-induced coupling strength is proportional to the product of the Rabi coupling strength by the gradient of the density of states of the reservoir. There is a critical Rabi coupling strength above which the environmental-induced coupling ensures that the system remains in the strong coupling regime at any relaxation rate. In this case, the strong coupling regime takes place even when the relaxation rate is significantly above the Rabi coupling strength between the subsystems. The critical coupling depends on the gradient of the reservoir density of states. We demonstrate that managing this gradient can serve as an additional tool to control the properties of the coupled systems.
Entropy production and fluctuation theorems in a continuously monitored optical cavity at zero temperature
Authors: Kewming Michael J. , Shrapnel Sally
Published: April 2022

Fluctuation theorems allow one to make generalised statements about the behaviour of thermodynamic quantities in systems that are driven far from thermal equilibrium. In this article we use Crooks' fluctuation theorem to understand the entropy production of a continuously measured, zero temperature quantum system; namely an optical cavity measured via homodyne detection. At zero temperature, if one uses the classical definition of inverse temperature β, then the entropy production becomes divergent. Our analysis shows that the entropy production can be well defined at zero temperature by considering the entropy produced in the measurement record leading to an effective inverse temperature βeff which does not diverge. We link this result to the Cramér-Rao inequality and show that the product of the Fisher information of the work distribution with the entropy production is bounded below by half of the square of the effective inverse temperature βeff. This inequality indicates that there is a minimal amount of entropy production that is paid to acquire information about the work done to a quantum system driven far from equilibrium.

Authors: Safaat Aat , Noviyanto Alfian
Published: April 2022

Abstract -- Screw Compressor is one type of air compressor in the main utility at the DSLNG LNG Plant. This Screw Compressor is used as instrument water (clean, oil-free, and dry air) produced by the Air Compressor Package (Tag No. 065-C-1001 A / B / C), which is dried by the Air Dryer Package (065-V-1001A / B) until it reaches a dew point of -40 degrees Celsius before being accommodated in the Instrument Air Receiver (065-D-1002). Water instruments are needed to operate instrumentation equipment such as actuated valves, control valves, and others.This research was conducted to analyze the failure of rotary screw compressors and their modifications. The failure occurred in the lube oil (lubricating oil), which was contaminated by water from the surrounding wet air. This failure analysis is done with a fishbone diagram and plans to overcome the problem by modifying the breather system. Analysis of this failure by looking for the water content into the lubricating oil. Know the results of the analysis of the increase in the vibration value of the bearing screw elements and check the effect of corrosion in the lubrication system using a borescope. In addition, taking corrective action (repair) so that there are no recurring problems by making modifications to the Breather System on the gear casing
F. M. Dostoevsky’s Anniversary on the Pages of Turkish Literary Journal “HECE”
Authors: Olcay Turkan
Published: April 2022

The article is an analytical review of the two-volume special issue of Turkey’s largest monthly literary journal “HECE” dedicated to the 200th anniversary of F. M. Dostoevsky. More than 80 scientists from Turkey, Russia, Ukraine, Bulgaria, Azerbaijan, Armenia, Iran and America took part in the anniversary collective work. The problematic and thematic diversity of the prepared issue reflects relevance and enduring significance of the great Russian writer’s key ideas for the modern world. Works in the issue, emphasizing the depth and indissoluble unity of Dostoevsky’s moral and ethical concepts, and the artistic and aesthetic systems created by him, also convince readers of the inexhaustible potential inherent in the literary heritage of the brilliant thinker and artist. Studies of Dostoevsky’s novels, short stories and journalistic works, collected under the same cover of the journal, are considered in the context of the writer’s entire literary work and in connection with the main vectors of the world literary process. The publication brilliantly implementes the idea of the head of the “HECE” publishing company Mr Omer Faruk Ergezen, and is carried out with high professionalism of the editor, Professor of Ankara University Birsen Karaca.
The Way-Road According to Dante and N. V. Gogol: “The Divine Comedy” and “Dead Souls”
Authors: Tomachinskiy Symeon (Vladislav V.)
Published: April 2022

N. V. Gogol loved Italy, was fluent in Italian and created “Dead Souls” mainly in Rome. The article notes that Chichikov’s journey in the poem “Dead Souls” partly echoes the journey presented by Dante in “The Divine Comedy.” The poems of Dante and Gogol begin with the image of road, each of the works has its own guide and direction of movement. But if in Dante’s work the movement is vertical, in “Dead Souls” it is horizontal. The article proves that Dante’s journey, although an incredibly difficult and dangerous test, appears to be a meaningful, logical, elegantly constructed way. This is the path through Hell and Purgatory to Paradise, to God, in which the whole Roman soul of the poet is expressed with his love for order, harmony, justice, legal and moral explanation of each step. Chichikov’s journey is a dangerous illegal adventure, his movement is chaotic, random, dictated by momentary circumstances. His trio of horses is rushing at full gallop in an unknown direction and with an unknown purpose. The article also proposes a version of the origin of the protagonist’s surname — Chichikov, associated with the Italian word “chichirone,” which means “guide, conductor.”
“Three Epochs” of the Creation of Nikolai Gogol’s Article on Russian Poetry. To the 175th Anniversary of “Selected Passages from Correspondence with Friends”
Authors: Vinogradov Igor A.
Published: April 2022

The creative history of N. V. Gogol’s article “What is Finally the Essence of Russian Poetry and Its Peculiarity,” the most voluminous chapter of his book “Selected Passages from Correspondence with Friends” (1847), and its relation to the poem “Dead Souls” are studied. Three long stages of Gogol’s work on the article, which ended with the burning of manuscripts, and the fourth, which ended with its publication, reveal a close connection with the content of the poem. Evidence of simultaneous maturation of the ideas of the article and the poem in the 1830s is summarized. It is proved that the article was prepared by Gogol for P. A. Pletnev’s journal “Sovremennik.” Unknown data on the second stage of work on the article in 1841–1842 are introduced into scientific circulation, the expansion of concept of the article at the third stage in 1843–1845, which led to its inclusion in the book of letters to friends in 1846, is traced. It is emphasized that, created over more than ten years, the article contains the final reflections of the writer on the importance of literature in the public and state life of Russia and is an irreplaceable auto-commentary to “Dead Souls.”
Dante’s Epic in Russian Literature: N. V. Gogol, I. A. Goncharov, F. M. Dostoevsky
Authors: Melnik Vladimir I.
Published: April 2022

“Dead Souls” by N. V. Gogol, the novel trilogy by I. A. Goncharov, “The Brothers Karamazov” by F. M. Dostoevsky form the line of “Dante’s epic” in Russian literature. Solving the problems of historical mission of Russia in the modern world and the fate of modern Russian man in a purely theological key, all three authors deeply and creatively comprehended the question of three-part structure of “The Divine Comedy.” Within the framework of “national utopia” (Gogol), the historically defined image of Russia’s movement from “sleep” to “awakening” (Goncharov), the ideal of “Christian socialism” (Dostoevsky), Russian writers raised the question of fundamental possibility of spiritual transformation for an individual and a nation, indicated for a modern man, infected with apostasy and selfishness, the way from the “hell” of modern life to the religious ideal, to the “paradise,” which all three considered achievable even in earthly life, although they understood it differently. The appearance of the “Dante’s epic” in Russian literature is predetermined, in particular, by its organic attraction to the Orthodox worldview, which determined the centuries-old productivity in art of such an archetype of human behavior as “sin — repentance — resurrection.”

An Enhanced Automatic Generation of CRUD Operations in React-JS
Authors: Karungu Timothy , Nderu Lawrence , Kaburu Dennis
Published: April 2022

Seeing that coding React-JS can be repetitive and prone to errors like
most other programming languages, which makes it a daunting task,
Automatic Code Generation (ACG) tools exist to help tackle this. The
current model used in most of the ACG tools for React-JS comes up with
components which is a fraction of the entire application when it comes
to coming up with the entire Create, Retrieve, Update and Delete (CRUD)
applications. Developers still need to come up with the logic of how
CRUD functionalities will be implemented in the code that was generated
by these models. This study seeks to address this gap by proposing an
enhanced automatic generating model for Single Page Applications (SPA)
in React-JS coined CRUD-Bolt. The study employs the USE questionnaire to
test its usability whereby 38 React-JS developers across the globe fill
the questionnaire after testing it. The results are imported into
Statistical Package for the Social Sciences (SPSS) to evaluate
CRUD-Bolt. The outcome of the study is threefold: achieve an enhanced
model coined CRUD-Bolt, make it available to developers, and test its
usability via SPSS.
Electrographic Flow Mapping for Persistent Atrial Fibrillation: Theoretical Basis and Preliminary Observations
Authors: Haines David , Kong Melissa H. , Ruppersberg Peter , Haeusser Philip , Avitall Boaz , Szili-Torok Tamas , Verma Atul
Published: April 2022

Ablation strategies remain poorly defined for persistent atrial
fibrillation (AF) patients with recurrence despite intact pulmonary vein
isolation (PVI). As the ability to perform durable PVI improves, the
need for advanced mapping to identify extra-PV sources of AF becomes
increasingly evident. Multiple mapping technologies attempt to localize
these self-sustained triggers and/or drivers responsible for initiating
and/or maintaining AF; however, current approaches suffer from technical
limitations. Electrographic flow (EGF) mapping is a novel mapping method
based on well-established principles of optical flow and fluid dynamics.
It enables the full spatiotemporal reconstruction of organized wavefront
propagation within the otherwise chaotic and disorganized electrical
conduction of AF. Given the novelty of EGF mapping and relative
unfamiliarity of most clinical electrophysiologists with the
mathematical principles powering the EGF algorithm, this paper provides
an in-depth explanation of the technical/mathematical foundations of EGF
mapping and demonstrates clinical applications of EGF mapping data and
analyses.

Genetic diversity and population structure of Lupinus albus (L.) from the Amhara region of Ethiopia using seed storage protein markers
Authors: Kelemu Selamawit , Shiferaw Eleni , Hailu Faris
Published: April 2022

The genetic diversity in 48 lupin (Lupinus albus (L.) accessions collected
from the Amhara region, Ethiopia, was assessed using seed storage protein
markers (SDS-PAGE). A total of 30 different protein bands with sizes ranging
from 11 to 100 kDa were detected. The average number of protein bands, the
percentage of polymorphism, and gene diversity in the accessions were 16.96,
20.35, and 0.072, respectively. Genetic diversity estimates showed that West
Gojam and Bahir Dar areas could be the most important sources for lupin
genetic resources. The pair-wise comparison of genetic distances (GDs) among
the accessions ranged from 0.011 to 0.378. The most distantly related
accessions were accession 6, collected from the West Gojam zone, and
accession 28 from the Bahir Dar area. Principal coordinate analysis (PCoA)
showed the absence of a distinct group, and most of the accessions were
intermixed. Population structure analysis revealed that the 48 lupin
accessions could be assigned to three clusters. Similar to PCoA, no defined
grouping based on geographic origin was observed. Accessions from different
geographic origins being grouped together could be attributed to a common
origin for the various accessions in the different zones, or it could be the
result of seed-mediated gene flow among different lupin growing areas of the
country.
Effects of organic and microbiological fertilizers on morphological and productive characteristics of triticale in the organic farming system
Authors: Roljevic-Nikolic Svetlana , Dolijanovic Zeljko , Zecevic Veselinka , Puvaca Nikola , Oljaca Snezana , Seremesic Srdjan
Published: April 2022

The aim of the study was to examine the impact of microbiological and organic
fertilizers on morphological and productive characteristics of triticale
during a three-year period (2009/10-2011/12). A two-factorial field
experiment was arranged using a randomized block design with four
replications. The object of the study was the triticale winter cultivar
Odisej, and the following treatments were applied: a control variant without
fertilization, microbiological fertilizer ?Slavol? (Agrounik Serbia) 5.0 l
ha-1, organic fertilizer ?Biohumus Royal offert? (Altamed RS) 3.0 t ha-1 +
microbiological fertilizer ?Slavol? (Agrounik Serbia) 5.0 l ha-1. The
results showed that the expression of the characteristics was significantly
affected by the environment. The lowest values were obtained in the first
year when the most unfavourable meteorological conditions were observed. The
application of microbiological fertilizer had no impact on the stem length
and grain weight per spike, but it significantly increased the number of
fertile spikelets (3.7%), spike length (7.7%) and grain yield (18.6%). The
combined application of fertilizers provided better results for all the
examined characteristics, while in comparison with the control, the
differences ranged from 4.3% for the number of fertile spikelets to 46.5%
for grain yield. The strongest correlation was determined between the spike
length and the number of fertile spikelets (r = 0.939**). The obtained
results lead to the conclusion that under variable environmental conditions,
the application of fertilizers has a significant impact on morphological and
productive characteristics of triticale, and consequently on the stability
of this crop production in the organic farming system.

Published: April 2022

The paper deals with agricultural and food companies which operated on the
territory of Vojvodina in 2019. The study analyzed the risk of bankruptcy
measured by the Altman?s Z-score method, as well as the profitability and
productivity of the observed companies. The aim of the study was to use a
multiple regression model to determine the impact of profitability and
productivity on the risk of bankruptcy for agricultural and food companies
of different sizes (including micro, small, medium and large companies) as
well as to compare the results for these two sectors. The comparison of
agricultural and food sectors was made according to the size of the
companies. The obtained results indicated that profitability has a
statistically significant positive impact on the risk of bankruptcy for
micro and large agricultural companies, while for small agricultural
companies, the risk of bankruptcy is statistically significant and
positively affected by productivity. The risk of bankruptcy for medium-sized
agricultural companies is not affected by the examined indicators. In
addition, regression analysis indicated that the risk of bankruptcy for
micro and small food companies has a statistically significant positive
impact on profitability. In contrast, for medium and large food companies,
the risk of bankruptcy is not affected by the observed variables.
Political economy of economic policy - the monetary reconstruction program (Serbia 1994) as a case study
Authors: Madzar Ljubomir
Published: April 2022

The paper deals with initiation and destiny of the unique 1994 Program of combating the extreme Serbian hyperinflation. Despite the originality of the Program and decisiveness with which the related steps had been undertaken, the Program lasted not much more than half a year. It turned out to be unsustainable as it is collided with inefficient institutional framework where contracts and rule of law were not honored, and employees, in self-managed firms, decided on their own remuneration. We show that for lasting stabilization a farreaching institutional reform was needed, and for implementing such reform an equally radical reform of the political system was necessary. However, there was not political will for these reforms, since they would oust the then political and economic elite from the power.
Olivera, Tanzi, Milosevic: Why was Avramovic’s programme adopted?
Authors: Popovic Dejan
Published: April 2022

It was under the UN sanctions during 1992 and 1993 that hyperinflation hit
the FRY. Its leadership believed that the fiscal deficit could be covered by
printing money, but such a practice resulted in acceleration of
hyperinflation. Former World Bank economist Dragoslav Avramovic understood
that stopping printing money should represent the core of his Programme. He
was aware of the Olivera-Tanzi effect, but the fierce attacks on the
Programme in the course of its presentation to the nation?s top leadership
indicated that those people were not - despite the fact that the real value
of all collected taxes decreased to only several tens of millions of US
dollars. It was ultimately Milosevic himself who decided that the Programme
should be approved. The economic problems of the FRY ran much deeper. The
involved interests of the nomenklatura in the real sector blocked further
reforms and Avramovic was dismissed in 1996.
Dragoslav Drag Avramovic: Probing the limits of development and stabilization policy
Authors: Vujovic Dusan
Published: April 2022

Dragoslav Avramovic was one of most accomplished economists in the area of
applied development policy. He came from a small country with limited
exposure to western economics, and made a stellar career at the World Bank
and the Brandt Commission. His main achievements include: (i) A novel
approach to external debt management based on dynamic assessment of
indebtedness and borrowing capacity. It differed from standard debt-to-GDP
ratio approach since it evaluated the efficiency and effectiveness of
borrowed resources. (ii) Model for reducing volatility of commodity prices
based on intervention fund (buffer stock) activated on either demand or
supply side to prevent excessive price changes. (iii) Stabilizing record
hyperinflation in his home country Serbia by introducing new currency, sound
macro-monetary policy, and breaking inflationary expectations that reduced
inflation and allowed price liberalization. He faced formidable political
economy opposition to implementing debt management and commodity
stabilization models, and structural reforms once the stabilization results
were achieved.
Spillovers of monetary policy shocks on financial markets during the crisis: Serbia and euro zone
Authors: Nedeljkovic Milan , Savic Nebojsa
Published: April 2022

The position of developing countries (DC) in the international financial
system is the topic on which Dragoslav Avramovic worked throughout his
successful scientific career. This paper extends his research towards an
empirical analysis of the importance of spillovers from the changes in the
monetary policy of the European Central Bank (ECB) on the country risk
premium and exchange rate in Serbia over the most intense phase of the Euro
crisis (2008-2012). Empirical results suggest that the ECB policy changes
during the crisis significantly spilled over to financial markets only in
several dimensions. The policies did not have a statistically significant
effect on the level of the exchange rate and of the risk premium. However,
they had a significant effect on the rise in uncertainty, especially in the
case of ECB?s foreign exchange liquidity and monetary stimulus measures. Our
empirical results imply that the changes in monetary policy in advanced
economies can drive uncertainty spillovers across the financial markets,
thereby also affecting the business cycle fluctuations in emerging markets
(EM).
150 years of the Serbian Medical Society
Authors: Colovic Radoje
Published: April 2022

May 4, 2022 marks the 150th anniversary of the founding of the Serbian Medical Society. For a nation, unlike ours, that has lived in peace for centuries, it would be an event of exceptional national significance and a reason for pride and satisfaction. In the context of difficult history of our people, which has lasted for centuries, such an event is incomparably more important. With such endurance and success, the Serbian Medical Society has become one of the oldest and most valuable institutions of our people and our state. It was founded on April 22, according to the Julian calendar (May 4, according to the Gregorian calendar) in 1872, during a century in which, after the failed First Serbian Uprising, the Serbs fought in the Second Uprising to become a vassal principality within the Ottoman Empire, and succeeded ? not merely using weapons, but also with wisdom and patience. Upon triumphing, its newly forming wisdom and its people first started to dream of full independence, and henceforth of the restoration of the Serbian state within its historical borders. Today, it is difficult to imagine the foresight and courage of the Serbian doctors to establish the Serbian Medical Society at a time when Serbia had only 63 doctors, seven of whom were ?masters of surgery? (medical assistants) and one dentist, all that at time when doctors of Serbian origin could be counted on the fingers of one hand. The Serbian Medical Society was founded soon after, or even before, medical associations in some advanced European countries for which the tragic history of the Serbian people was something they could hardly believe.

Global environmental modification especially increasing atmospherical carbon dioxide concentration and temperature can have an effect on most ecosystems. The various responses of plants to those aspects of world environmental modification are well documented. Arbuscular mycorrhizal fungi mediated plant play a vital roles in worldwide ecosystems, and protects host plants against environmental stress together with the uptake and transfer of macro and micro nutrients, modification of the physical soil surroundings and alteration of plant interactions with different ecology and environment systems. Numerous studies have incontestable the potential for variation in mycorrhizal fungal diversity to additionally have an effect on ecosystem functioning, in the main via effects on primary productivity. Diversity in these studies is sometimes characterised in terms of the quantity of species, distinctive organic process lineages or complementary mycorrhizal traits, also because the ability of plants to discriminate among arbuscular mycorrhizal fungi in area and time. However, the nascent outcomes of those relationships are sometimes indirect, and therefore context dependent, and difficult to predict with certainty. Central opinion of arbuscular mycorrhizal fungal multifariousness, ecosystem function relationships that concentrate on the direct and specific links between arbuscular mycorrhizal fungi fitness and consequences for their roles in ecosystems particularly highlight functional diversity in hyphal resource economics. In natural ecosystems, predict that world environmental modification effects on mycorrhizal fungal communities are going to be powerfully mediate by the impacts on plant communities to the extent that community level interactions can encourage be the key mechanism for determinative world environmental modification elicited changes in mycorrhizal fungal communities. It’s accepted that arbuscular mycorrhizal fungi interdependency can cut back chemical fertiliser and pesticide inputs. Consequently, this may result in a reduction in harmful chemical substance impact on surroundings. The key effects of arbuscular mycorrhizal fungi practical interdependency are often summarized as improving rooting and plant establishment, improving uptake of low mobile ions; improving nutrient cycling; enhancing plant tolerance to (biotic and abiotic) stress; improving quality of soil structure; enhancing plant community diversity and changes ecology and marginal/ novel environments. Present manuscript, the ecological and environmental characteristics of arbuscular mycorrhizal fungi, effects of arbuscular mycorrhizal fungi on host plant, and ecologic significance of arbuscular mycorrhizal fungal biotechnology in agricultural system and globe sustainable development were reviewed.
Review Study on Current Bread Wheat (Triticum aestivum L.) Production Status and Key Challenges for Potential Efficiency of Wheat Markets in Ethiopia
Authors: Abboye Anbessie Debebe
Published: April 2022

The main aim of this review study is to provide an overview of current wheat production status and the key challenges of future bread wheat marketing competence in Ethiopia. Bread wheat (Triticum aestivum L.) is a prevailing crop in temperate countries and is being used as one of a human sustenance. It is also an important basic food crop in Ethiopia. The success of wheat production depends somewhat on its adaptability and high yield potential, and also based on the gluten protein fraction, which confers the visco-elastic properties that allows its dough to be processed into bread, pasta, noodles and other food products. Improving bread wheat production and productivity as well as facilitating its marketing access is therefore one of a key part of the economic growth strategies in the Ethiopian government’s food self-sufficiency policy programs. The government’s policy interventions that aimed at improving bread wheat production or agricultural production for that matter, however, require involvements beyond the farm lands at the entire bread wheat value chains. Both local production and import are the two key sources of wheat grain supply to the Ethiopian bread wheat value chain have shown a substantial increase since the mid-1990s. So far, a steady increase in domestic wheat consumption has resulted in rising bread wheat and product prices over the forgoing two decades. For instance, bread wheat grain, wheat flour as well as wheat bread prices have all being more than doubled between 2000 and 2020. Using a qualitative survey of selected bread wheat value chain actors and a review of existing literature, this study provides an overview of the bread wheat value chain, institutional and marketing arrangements, and trader behavior of bread wheat value chain actors in Ethiopia. The bread wheat value chain consists of multiple actors that include several small holder farmers and the Ethiopian grain trade enterprise at the upstream and urban and rural consumers at the other end. The study stresses the need for formulation of bread wheat market-enhancing policies, such as quality control and dispute settlement mechanisms as well as better access to market information, to improve bread wheat productivity as well as marketing efficiency.
Diversity of Wild vs Cultivated Plants in Indonesian

Published: April 2022

Indonesia is one of the centres of biodiversity in the world. Forests in Indonesia are one of the richest in the world. On the other hand, Indonesia is also the country with the highest destruction of its forests. Forest area continues to decline due to forest burning, land conversion and illegal logging. This has caused wild plants decreased. Meanwhile, domestications and plant breeding has caused the increase of cultivated plant varieties. However, cultivated plants are also decreasing when the quality do not match the demand.

Published: April 2022

The fungi forming arbuscular mycorrhizal fungi (AM fungi) are obligate symbionts microbe that predominates with inside the roots and soil of land flora. AM fungi are monophyletic group of phylum Glomeromycota. The AM fungi now no longer simplest arise in roots however additionally produce hung networks of extraradical mycelium (ERM) indeterminate length, spreading from host roots into the encompassing soil and establishing belowground interconnections amongst plants belonging to the identical or to unique taxa, in which they form a dense mycelial network (MNW). Reproduction in AM fungi takes place via asexual spores, which might be produced at the hyphae tips. These thick-walled spores stay with inside the soil for prolonged periods of time. AM fungi facilitate host plants to develop vigorously beneath stressful situations with the aid of using mediating a chain of complicated conversation occasions among the plant and the AM fungus leading to enhanced photosynthetic rate and other gas exchange in addition to improved water. AM fungi provide key nutrients to host plant lifespan. AM fungi transfer phosphorus (P), other macro and micro nutrients, along with water to the hosts of grassland and tropical forest plants in exchange for sugars. AM fungi form a network of filaments that associate with plant roots and draw nutrients from the soil that the root system would not be able to access otherwise. AM fungus plant alliance stimulates plant growth and accelerates root improvement in nearly all crops. The AM fungal extraradical hyphae (ERH) alongside glomalin connected soil protein (GCSP) extensively influence the soil carbon dynamics (SCD) and enhance soil and plant health. They additionally increase the resistance in plants against plant pathogens and surface area of root system for higher absorption of nutrients from soil. Therefore, they can be used as biofertilizer in addition to biocontrol agent. Present manuscript delineated the prospective of AM fungi as a biostimulants can potentially strengthen plants' adaptability to converting Agriculture system for green technology
