Authors:   Mytischi Branch of Bauman Moscow State Technical University, KOLNICHENKO GEORGY , TARLAKOV YAKOV
Published: January 2023

When creating and improving power supply systems, steady-state calculations are the most common, they contain nonlinear elements in the form of generators and loads, therefore their steady-state mode is described by nonlinear equations. The solution of such equations is possible only by iterative methods, which is associated with the problem of convergence of the iterative process. Due to some features of electrical systems, which are inherent, including power supply systems of the agro- and forestry complex, the convergence of the iterative process may be slow and not even secured. (Research purpose) The research purpose is developing a method for calculating the steady-state modes of power supply systems that meets the condition of convenience of implementation on an electronic computer and removes the problem of convergence of the iterative counting process. (Materials and methods) Proposed a direct calculation method with cyclic correction of the initial information for each cycle in order to take into account the nonlinearity of elements of power supply systems. (Results and discussion) The calculation formulas for determining the intrinsic and mutual resistances that underlie the proposed method are given, their main feature is that they are distributed with elements included in the nodes corresponding to sources and loads, and obtained by the authors as a result of the transformation and solution of nodal equations. It was established that the method is implemented through the operation of the following algorithms: calculation of intrinsic and mutual resistances; calculation of current distribution, that is, determination of currents in the branches of the network; calculation of voltages in all nodes of the power supply system; calculation of power flow distribution in order to subsequently identify power losses and electric energy consumption. (Conclusions) It was shown that the derived universal calculation expressions can also be used for equivalence purposes. It was revealed that the proposed method and the algorithms implementing it are relatively easy to program and provide the necessary speed and accuracy of calculations; they are designed to solve practical problems related to the design and operation of complex closed power supply systems, increasing their reliability and efficiency.

Published: January 2023

The analytical, calculated possibility of realization of the picking of cargo after harvesting solid crops of breeding seeds, regardless of the operation of the selection and seed harvester, is considered. A distinctive feature of independent cargo selection in pre-breeding is significant harvesting areas, from which the transportation of already packed crops requires fixed approaches to route construction to minimize significant over-runs, the number of options of which is determined by factorial dependence. (Research purpose) The research purpose is scientifically substantiate the methods of movement of vehicles in the field with manual selection of sacks in conditions of technologically independent harvesting of continuous crops of breeding seeds of grain crops. (Materials and methods) Used well-known methods of movement of the machine-tractor unit, which can be adapted to the selection of grain samples filled from the combine. It was revealed that the computational solution of the problem may imply the most convenient adaptation of the number permutation generator for the calculation of shortest routes. (Results and discussion) Analytical methods of circular movement of the vehicle and shuttle, if necessary, compliance with the sequence of the technological operation of cleaning, were proposed. Presented, if there is a calculation base, a method of movement through the nearest points, and if necessary, compliance with the sequence of the technological cleaning operation - through a sequence of points. (Conclusions) It was found that the presence of a calculated base of routes by passing the nearest points reduces the mileage by 1.27-2 times compared to the analytical method of circular motion. It was determined that the use of a calculated database of routes by passing a sequence of points reduces mileage in comparison with the analytical shuttle method by 2.19-3.23 times. It was shown that some of the parameters are rounded up, so at this stage it is recommended to use the data obtained in the framework of engineering calculations of the vehicle’s cycleway.

The destruction of the structure of over-compacted soils on the vibrating surfaces of the working bodies of chisel deep-diggers is a technological process that occurs faster and more efficiently than when moving the working bodies of chisels inside the bulk medium of deep-diggers in a calm state. Of great importance are the vibration modes exerted on the technological process, which allow reproducing vibrations of the specified amplitudes and at a high frequency of vibration vibrations of the vibration exciter transmitted to the active parts of the working bodies of chisel deep heaters. (Research Purpose) The research purpose is developing software, hardware and technical means for digital monitoring, automation and robotization of production and technological processes in the technologies of cultivation of grain crops. (Materials and methods) Used methods of analysis and modeling of the process. (Results and discussion) It was determined that the use of vibration vibrations for the destruction of anthropogenic over-compacted soil makes it possible to destroy dense fragments of soil and turn the structure of the destroyed soil into a fertile layer in which a developed root system is formed, suitable for obtaining high yields. It has been established that intensive technologies that transmit vibration vibrations to the active working organ of an agricultural machine by using an unbalanced mass in the vibration mechanism, intensively rotated inside the body of the vibration exciter from the external force of the tractor, excite vibration vibrations transmitted to the active working organs of chisel machines, which excite the vibration treatment of anthropogenically over-compacted soil. (Conclusions) It was revealed that among the intensive technologies that transmit vibration vibrations to the working body of an agricultural machine, it is necessary to include machines with NM that excite vibration vibrations transmitted to the working body that excites the vibration treatment of the processed technological medium. The calculated values of the converted NM average power were presented.
Development of Reading Ability in Childhood by the Example of Georgian Language
Authors:   Ivane Javakhishvili Tbilisi State University, Georgia, Shavshishvili Maia
Published: January 2023

Reading as a skill is divided into many subskills, which take almost entire early childhood to develop. Children go through stages of getting comprehension of phonemes and grammar structure until they can connect letters to sounds and read without problems. Learning how to read in second language is usually harder because of new sets of phonemes and differences in alphabet. On the other hand, learning how to read Georgian Language might be easier than most other languages. Georgian Language has 33 phonemes and 33 letters of alphabet, which directly correspond to each other. Reading is straightforward due to no differences between what is written and how it should be pronounced. The article will be covering how reading skill develops in children and how these aspects might be connected to learning to read Georgian.

Published: January 2023

The article deals with the problem of lingua-cultural peculiarities of tourism discourse, contrastive analysis of English and Georgian tourism-related vocabulary and terminology, and outlook of teaching tourism discourse to students or people who are interested in the field of tourism. Tourism discourse is an independent type of discourse that has a specific addressee and it refers to communication among people who do not belong to a specific social or cultural group or language community. Therefore, our main focus will be addressed to reveal language peculiarities of English and Georgian tourism discourse to make the teaching process easier for any group of people who are interested in understanding the specific terms and expressions used in the texts. Revealing lingua-cultural differences and similarities between the chosen English and Georgian texts contributes to a better understanding of various cultures and traditions. Thus, the paper aims to research the vocabulary and terminology of the tourism discourse and to select the appropriate terminology for teaching tourism-related texts considering their lingua-cultural peculiarities. The research based on contrastive analysis of English and Georgian tourism-related texts shows that in professional and academic tourism discourses certain terms and special vocabulary are observed, in public tourism discourse - evaluative vocabulary and emotional connotations prevail. Lingua-cultural analysis of the tourism-related English and Georgian texts showed that they are characterized by an abundance of borrowed words and lacunas, although the use of idioms is rare. The conclusions drawn in the paper contribute to the further research of tourism texts. In addition, it should be noted that the work is interdisciplinary, and it will be useful not only for specialists working in the tourism industry but for philologists and teachers teaching English to students qualifying in tourism..
Estudio de la precisión de modelos de marea mediante la varianza de los residuos de alturas satelitales en la plataforma patagónica
Authors: de Azkue María Florencia , D'Onofrio Enrique Eduardo , Jacbos Alan
Published: January 2023

This work proposes to compare the astronomical tidal predictions obtained by using the totality of the constituents provided by seven global tide models and by the Center for Topographic studies of the Ocean and Hydrosphere (CTOH). To quantify this comparison, the variance of residuals of satellite sea level heights are computed from 1992 to 2019, for each model and CTOH. As a case study, we focus on the Patagonian shelf. It is found that the most accurate tidal predictions are obtained when using FES2014 model and CTOH harmonic constants. It is also observed that the decrease in variance values is due to the addition of certain minor constituents. As an example, in the case of CTOH, a location yields a reduction of more than 57% in the variance values when 9 minor constituents are added to the nine common ones. Likewise, in the case of FES2014, variance reduction over this same location is more than 56% by incorporating 14 minor constituents. Finally, a comparison of the amplitudes and phases values of the common constituents among models and the CTOH shows that these values are practically the same. However, when comparing predictions, very dissimilar results are obtained among models
Kan pensionisten slappe af?
Authors: Hansen Christian Langelund
Published: January 2023

Med jævne mellemrum går en af mine kollegaer på pension. Jeg stiller altid vedkommende spørgsmålet: »Hvad skal du så lave nu?«. Alle har gjort sig overvejelser og opremser alverdens aktiviteter, de har planlagt. Ingen har nogensinde givet mig svaret: »Jeg skal ikke lave noget som helst. Jeg skal bare sidde i en gyngestol, slappe af og nyde min alderdom. Det har jeg nemlig fortjent efter et langt arbejdsliv «. Egentlig er mit obligatoriske spørgsmål også et udtryk for, at jeg implicit forventer, at de skal foretage sig nogle nyttige ting, og at deres tilbagetrækning fra arbejdsmarkedet ikke er en tilbagetrækning fra livet. Men hvad ligger til grund for, at mine kollegaer alle har en lang to-do-list for deres alderdom? Hvad ligger til grund for, at jeg, og det omgivende samfund, ubevidst forventer rigtig meget af de personer, der står på tærsklen til en pensionisttilværelse? Dette er efter min overbevisning et udtryk for, at der hersker en kraftfuld diskurs om aktiv aldring. Men hvorledes stiller det alle dem, der ikke har forudsætningerne for at leve et aktivt seniorliv, og hvad gør vi ved det? På denne baggrund diskuterer jeg i dette essay spørgsmålet: »Kan pensionisten slappe af?«
Samfundstanker i en pandemitid
Authors: Rasborg Klaus
Published: January 2023

I efterhånden mere end et år har vi måttet leve med en radikalt forandret virkelighed forårsaget af en usynlig virus, der angiveligt sprang fra flagermus til menneske i storbyen Wuhan i Hubei-provinsen i Kina. Som en steppebrand spredte den sig ikke blot til Europa, men til den ganske verden. I løbet af et splitsekund blev også det ellers på mange måder relativt trygge danske velfærdssamfund forvandlet til et »pandemisk samfund« i noget nær undtagelsestilstand. Få havde set det komme, og endnu færre var, og er, i stand til at sige med sikkerhed, hvor længe det vil vare endnu. Økonomernes rolle som de fremmeste prognosemagere blev overtaget af epidemiologerne, der på daglig basis i medierne kommer med risikovurderinger, beregninger og estimater over epidemiens udvikling. Sociologer, politologer, psykologer og filosoffer har imidlertid også blandet sig i debatten og fremlagt analyser af, hvad coronakrisen har gjort ved os både på det individuelle og på det samfundsmæssige plan. Heriblandt også den italienske forfatter og fysiker Paolo Giordano, den bulgarske samfundsforsker Ivan Krastev og den slovenske sociolog og filosof Slavoj Zizek, som i tre små »coronabøger« hver især har givet et bud på dette.
Efter volden? Hverdagsliv og familieliv blandt børn og mødre på krisecenter
Authors: Henze-Pedersen Sofie
Published: January 2023

Ph.d.-afhandlingen »Efter volden?« undersøger, hvordan børn og deres mødre oplever og praktiserer hverdags- og familieliv på et dansk krisecenter. Gennem en etnografisk tilgang udforsker afhandlingen de intime praksisser, der udspiller sig bag krisecenterets fire vægge. Krisecenterets institutionaliserede og semi-offentlige miljø danner rammen og bliver en strukturerende mekanisme for hverdagen og familielivet her. Med et særligt fokus på praksisser belyser afhandlingen, hvordan barndom og familie ’gøres’ i disse institutionelle rammer. Det sker med afsæt i teorier fra barndomssociologien (se fx James, Jenks, & Prout, 1998; Rasmussen, 2004), familiesociologien (se fx Finch, 2007; Morgan, 1996, 2011) og den levede oplevelse af vold (se fx Das, 2007; Das & Kleinman, 2000).

At falde fra – beretninger om religiøst frafald på tværs af majoritetsdanske og minoritetsetniske miljøer
Authors: Liversage Anika , Özkaya Betül
Published: January 2023

Religiøst frafald i Danmark har ikke haft stor bevågenhed i forskningen. Ud fra biografisk narrative interviews med personer fra et »Meningsdannernetværk « undersøger artiklen derfor beretninger om frafald blandt både majoritetsdanskere og etniske minoriteter. Her ses klare fællestræk, uanset om man forlader kristendommen eller islam. Forløbene, fra man oplever den første tvivl til ens endelige brud med religionen, kan være særdeles udfordrende, blandt andet fordi det religiøse frafald kan få alvorlige sociale konsekvenser. I mindre kristne menigheder, såsom Jehovas Vidner, forekommer en stærkt institutionaliseret udstødelse af »frafaldne«, mens processen er mindre fastlagt, og kan være meget konfliktfyldt, i en muslimsk kontekst. Såvel oplevelser af sociale repressalier, som stor eksistentiel usikkerhed, kan bidrage til, at nogle »frafaldne« efterfølgende døjer med alvorlige psykiske udfordringer. Afslutningsvis diskuterer artiklen, hvordan »Meningsdannernetværkets« personlige beretninger om frafald indgår i en samfundsmæssig kontekst, hvor indvandreres og islams rolle er et emne, der udspiller sig forskellige samfundsmæssige kampe omkring. Dette kommer dels til udtryk ved, at deltagelsen af ekskristne netværksmedlemmer førte til en skarp politisk kritik af initiativet. Dels ved, at nogle etniske minoritetsmedlemmers fortællinger i højere grad handler om at forhandle og flytte på grænser, frem for kun om at ændre ens personlige placering i et statisk landskab.

Evaluating Diabetes Group Medical Visits in a Family Medicine Residency Program
Authors: Wegner Elfie , Cheng Adonis , Johnson Christina , Carbone Antonia , Florio Nick , Washington Judy C.
Published: January 2023

Background: Group medical visits (GMV) have been shown to improve metrics in patients with type 2 diabetes mellitus (DM). Overlook Family Medicine, a teaching residency program, anticipated that medical residents trained in the GMV model of care by interdisciplinary team members may improve cholesterol, HbA1C, BMI, and blood pressure in patients. The objective of this study was to compare metrics between group 1: GMV patients with DM whose primary care provider (PCP) was an attending physician/nurse practitioner (NP) and group 2: GMV patients with DM whose PCP was a family medicine (FM) medical resident receiving GMV training. We seek to provide guidance on implementation of GMV in residency teaching practices.
Methods: We performed a retrospective analysis to evaluate total cholesterol, LDL, HDL, TG, BMI, HbA1C, and BP in GMV patients between 2015-2018. We used a t test to compare outcomes between the two groups. Diabetes training was provided to family medicine residents by an interdisciplinary team.
Results: There were 113 patients enrolled in the study: 53 in group 1 and 60 in group 2. There was a statistically significant decrease in LDL and triglycerides, and an increase in HDL in group 2 (P<.05). There was a clinically significant decrease in HbA1C in group 2 (-0.56, P=.0622).
Conclusion: Sustainability of GMV can be achieved with a champion diabetes education specialist. Interdisciplinary team members are integral in training residents and addressing patients’ barriers. GMV training should be incorporated into family medicine residency programs to improve metrics for patients with diabetes. FM residents who received interdisciplinary training had improved metrics in GMV patients compared to patients whose providers did not. Therefore, GMV training should be incorporated into family medicine residency programs to improve metrics for patients with diabetes.

Published: January 2023

Batik is the art work of the Indonesian people which is a cultural heritage from their ancestors which has become one of the world's recognized cultural heritages. Batik itself has a variety of patterns that are influenced by the customs of the local community and contains deep meaning and philosophy. Endemic flora and fauna are often used as patterns for batik motifs. In the process of forming batik motifs, mathematical knowledge is often required which sometimes appears naturally. Mathematics that is closely related to culture is called ethnomathematics as a branch of mathematics. Ethnomathematics can be used in forming batik patterns, especially fractal forms. A fractal shape is an object that appears to have a symmetric self-resemblance to one another when viewed at a certain scale and is the smallest part of the overall structure of the object. The purpose of this research is to make fractals of local batik motifs from Central Sulawesi using the endemic plant of Bunga Katimong (Etlingera Elatior) with the help of the j-Batik application so that new motifs are obtained to add to the diversity of existing batik motifs. The new batik motifs produced in this research are Katimong, Kantan, Kincung and Honje.

dΧΥ to infer local adaptive evolution
Authors: Nam Kiwoong
Published: January 2023

The distinction of loci under local adaptive evolution from background
selection has been one of the main challenges to evolutionary
genomicists. Matthey-Doret and Whitlock (2019) concluded from their
simulation that background selection does not affect
F severely for the inference of local
adaptation. Even though this conclusion is logically correct, the field
of evolutionary genomics will be benefited much more if the conclusion
were ‘d should be used to infer local
adaptation’.
Effects of non-proportionality and tension-compression asymmetry on the fatigue life prediction of equivalent stress criteria
Authors: Kuhn Michael , Manousides Nikolas , Antoniou Alexandros , Balzani Claudio
Published: January 2023

Biaxial tension/compression-torsion fatigue tests with varying
levels of non-proportionality were performed employing a structural
adhesive designed for wind turbine rotor blades. The cycles to failure
were found to be independent of the level of non-proportionality. It is
demonstrated that numerical fatigue life predictions via
rainflow-counted equivalent stress histories are not able to replicate
these experimental observations and overestimate the fatigue life up to
a hundredfold. The tension-compression asymmetry of the adhesive
resulted in significant damage prediction differences depending on the
stress space representation of the Haigh diagram. If not properly taken
care of, the asymmetry will also lead to non-conservative results. While
demonstrated with a short fiber reinforced adhesive, the results can be
transferred to other materials.

Published: January 2023

Nature has provided unique molecular scaffolds for applications
including therapeutics, agriculture, and food. Due to differences in
ecological environments and laboratory conditions, engineering is often
necessary to uncover and utilize the chemical diversity. Although we can
efficiently activate and mine these often complex 3D molecules,
sufficient production of target molecules for further engineering and
application remain a considerable bottleneck. An example of these
bioactive scaffolds are armeniaspirols, which are potent polyketide
antibiotics against gram-positive pathogens and multi-resistance
gram-negative Helicobacter pylori. Here, we examine upregulation
of armeniaspirols through engineering of biosynthetic pathways and
primary metabolism; including perturbation of genes in biosynthetic gene
clusters and regulation for triacylglycerols pool towards armeniaspirol
upregulation. With either overexpression of extender unit pathway or
late-stage N-methylation, or the deletion of a competing
polyketide cluster, we can achieve 7-49-fold upregulation of
armeniaspirols production. The most significant upregulation was
achieved by expression of heterologous fatty acyl-CoA synthase, where we
observed not only a 97-fold increase in production yields compared to
wild type, but also an increase in the diversity of observed
armeniaspirol analogs.

Biosafe wearable healthcare monitor has attracted significant attention
owing to their applicability to wearable electronics. However, the
narrow sensing range and poor response limit the application of flexible
devices for comprehensive monitoring of human health-related
physiological signals (i.e. pulse diagnosis). Critical challenges remain
in the development of biocompatible materials and the design of flexible
bio-integrated platforms for these purposes, targeting performance
approaching those of conventional wafer-based technologies and long-term
operational stability. In this context, this work presents a robust and
flexible MXene/polydopamine (PDA)-composite-film-based pressure sensor
in a portable/wearable fashion, which establishes a unique intercalated
spherical-like PDA molecules structure, thereby resulting in excellent
sensing performance. The MXene/PDA-based pressure sensor has sensitivity
of up to 138.8 kPa-1 in the pressure range of 0.18-6.20 kPa with fast
response and recovery speed (t1<100 ms; t2<50 ms).
Associated embodiment involves real-time precise measurements of a
variety of health-related physiological signals, ranging from wrist
pulse, to finger motions, to vocalization and to facial expressions,
with high sensitivity and accuracy. Studies on human subjects establish
the clinical significance of these devices for future opportunities of
health monitoring and intelligent control to predict and diagnose
diseases.
E. coli DNA Repair Helicase Lhr is also a Uracil-DNA Glycosylase
Authors: Bolt Ed , Buckley Ryan J. , Hanson Karl M. , Ahmed Nadia R. , Cooper Christopher
Published: January 2023

DNA glycosylases protect genetic fidelity during DNA replication by
removing potentially mutagenic chemically damaged DNA bases. Bacterial
Lhr proteins are well-characterized DNA repair helicases that are fused
to additional 600-700 amino acids of unknown function, but with
structural homology to SecB chaperones and AlkZ DNA glycosylases. Here
we identify that E. coli Lhr is a uracil-DNA glycosylase that
depends on an active site aspartic acid residue. We show that the Lhr
DNA helicase activity is functionally independent of the uracil-DNA
glycosylase activity, but that the helicase domains are required for
fully active uracil DNA glycosylase activity. Consistent with uracil DNA
glycosylase activity, deletion of lhr from the E. coli
chromosome sensitized cells to oxidative stress that triggers cytosine
deamination to uracil. The ability of Lhr to translocate single-stranded
DNA and remove uracil bases suggests a surveillance role to seek and
remove potentially mutagenic base changes during replication stress.

Published: January 2023

Monkeypox infections in the US and across the world have been rising in
the past few months. Most of these infections have been found to be
transmitted among men who have sex with men (MSM). Our case report
discusses the rare presentation of a patient with monkeypox along with
multiple comorbidities, including AIDS, late latent syphilis, acute
hepatitis C, and asymptomatic and scrotal and penile cellulitis
secondary to MRSA. Further, our case report raises discussion on the
need for further research to identify the effect of monkeypox vaccine on
symptomatic patients who are immunocompromised.
Obtaining novel data-driven hypotheses from teaching activities: an example assessing the role of the FKBP5 gene in major depression

Published: January 2023

Many clinical and research efforts aim to develop antidepressant drugs
for those suffering from major depressive disorder (MDD). Yet even
today, the available treatments are suboptimal and unpredictable, with a
significant proportion of patients enduring multiple drug attempts and
adverse side effects before a successful response; and for many
patients, no response at all. Thus, a clearer understanding of the
mechanisms underlying MDD is necessary. In the “Brain development and
disease” class of our Master’s program in Cognitive Sciences, we ask
students to collect data about the expression of a gene whose altered
expression and/or function is related to a brain disorder. The students’
final exam assignment consists of writing a research article in which
the collected data are discussed in relation to the relevant disorder.
In the course of one of these students’ assignments, we identified the
FKBP5 gene as a key player uniting two major hypotheses of MDD
pathogenesis and treatment response. FKBP5 is involved in biological
processes including immunoregulation and glucocorticoid function, both
of which are separately implicated in the development and prognosis of
MDD. Gene expression analysis from the human and non-human primate Allen
Brain Atlases revealed that FKBP5 is expressed in brain regions involved
in MDD, particularly at periods of development when early-life stressors
would have a great effect. Future works should focus on causal
mechanisms of FKBP5 for antidepressant response. Our experience shows
that classes engaging students in data collection and analysis projects
may effectively result in novel data-driven hypotheses.
Research Into Potential Therapies Against COVID-19, With Focus On Ivermectin
Authors: Khanghah Reza Rezaie
Published: January 2023

Purpose: Ivermectin is a broad-spectrum antiparasitic and an effective
drug to treat COVID-19. In this article, we looked at the effects of
ivermectin on coronavirus and its patients in three ways. We have
discussed and organized other previously discovered potential therapies
and reviewed them in Table 2 and in the last section. Methods: We
searched for articles on MedRxiv, PubMed, Google Scholar, MEDLINE,
EMBASE uses the appropriate search terms. ClinicalTrials.gov was
searched for available clinical trials evaluating the effectiveness of
ivermectin. We also use EU clinical trial registry data and ANZ registry
data for clinical trials. Also, we performed our methods in 4 stages:
Identifying studies, Selection of Studies, Collating Studies, Reporting
results. Results: Results are variable. Some studies have shown the
effectiveness of ivermectin, others have not. Furthermore, some studies
show that a combination of ivermectin with other drugs is useful.
Conclusion: Overall, we believe the reason ivermectin is useful is that
it goes back to its origin, which is soil. Our theory and hypothesis is
that if the coronavirus, created by man or by nature, can generally be
treated with nature, that is, the soil. The interesting thing is that
today we know that ivermectin is effective in the fight against the
coronavirus. In fact, other drugs like teicoplanin, cyclosporine and
rapamycin that are effective against the coronavirus have come from the
soil. We hope that this article has been able to take a step in finding
a corona drug, InshaAllah.
Multi-Objective Workflow Optimization Algorithm based on Dynamic Virtual Staged Pruning Strategy
Authors: Zhi-yong Luo , Shan-xin Tan , Xin-tong Liu , Hai-feng Xu , LIU jiahui
Published: January 2023

Time, cost, and quality are the main factors affecting industrial
production, and balancing various constraints to make the production
parameters reach the optimal value is an NP-hard problem. With the
progress of process production, the production process of various
products is more refined, and in the actual production process, the
production process has the characteristics of multi-stage and parallel
proceeding, therefore, for the difficult problem of multi-stage and
non-linear production process optimization, this paper proposes a
workflow multi-objective optimization algorithm ( DVSP) based on
dynamic virtual phased pruning strategy, which is divided into three
stages, firstly, eliminating the indirect constraint relationship
between tasks by pruning strategy and simplifying directed acyclic graph
(DAG), secondly, dividing the task node set by virtual hierarchical
strategy and generating virtual nodes by using virtualization
technology, and finally, calculating the stage in stages by an inverse
reductive contracting optimal set of service nodes, forward scheduling
generates the optimal path, and the global optimal solution is sought
through algorithmic integration. After experimental comparison, the
algorithm has a more obvious optimization effect than the traditional
critical path algorithm and mass maximum algorithm, which meets the
actual production needs.
Multi-functional Nitrogen Fixing, Phosphate Solubilizing and Potassium Solubilizing Isolates from Flood Affected Regions of Kerala

Published: January 2023

A study was under taken to isolate and screen selected beneficial
microbes, which can restore soil fertility in the chosen flood-affected
areas of Attapady and Nelliyampathy in Palakkad district of Kerala,
India. A total of 76 isolates (40 N-fixers, 26 P-solubilizers and 10
K-solubilizers) were obtained from the flood affected areas. Triple
enzyme activities of cellulase, laccase and dehydrogenase were recorded
in 47.36% of N-fixers from Attapadi, 36.36% P-solubilizers and 60%
K-solubilizers from Nelliyampathy. Six diverse maximal enzyme producers
were selected based on study of microbial dry weight and plant
growth-promoting characteristics, including nitrogen(N) fixation,
phoshphate(P), potassium(K), and indole acetic acid(IAA) synthesis.
These 6 isolates were ranked according to all the evaluated
characteristics using statistical analysis, and the top 3 isolates were
found. The most efficient multi-functional N-fixer was identified as
Priestia megaterium from Attapadi which ranked first, Aspergillus
terreus as the most capable P-solubilizer from Nelliyampathy and
Talaromyces pinophilus as the most proficient K-solubilizer from
Nelliyampathy. The competence of these three isolates from flood
affected regions could help in the rejuvenation of the soil organic
matter (SOM) in degraded soils. However further evaluation under field
conditions are required to confirm these results.
