Imlifidase Utilization in Glanzmann Thrombasthenia with Anti-GPIIb/IIIa and Anti-HLA Alloimmunization and Severe Platelet Refractoriness following Hematopoietic Stem Cell Transplant.
Authors: AlNajjar Mohammad , Rochat Ryan , Grimes Amanda , Navaei Amir , Eagar Todd , Martinez Caridad , Yassine Khalid , Krance Robert , Bhar Saleh
Published: May 2024

Glanzmann Thrombasthenia (GT) is an inherited bleeding disorder of poor
platelet function secondary to a defect in platelet membrane
glycoprotein IIb/IIIa (GPIIb/IIIa). Patients with GT may develop
anti-platelet antibodies including anti-GPIIb/IIIa which can lead to
severe refractory thrombocytopenia and life-threatening bleeding,
management of which is challenging. We report successful use of
imlifidase, a novel IgG protease enzyme, as part of a multimodal
approach for management of severe platelet refractoriness and
alloimmunization in a child with GT and primary graft failure following
hematopoietic stem cell transplant (HSCT). The patient had no detectable
anti-platelet alloantibodies following imlifidase, and underwent a
second HSCT.

Authors: WN Kelly , MJ Ho , T Smith , K Bullers , Bates David W. , A Kumar
Published: May 2024

Background: Adverse drug events (ADEs) are a frequent cause of
injury in patients. Our aim was to assess pharmacist interventions and
their association with ADEs and potential adverse drug events (PADE).
Methods: The search criteria: a published RCT, evidence of a
pharmacist intervention, a comparison control group, and measurement of
ADEs or PADEs. The information sources included MEDLINE, Embase, and two
other databases through September 19, 2022. The risk of bias was
assessed using the Cochrane tool for RCTs. A random-effects model for
pooled studies was employed Results: Fifteen references meeting
inclusion criteria were discovered. For ADEs, the pooled results showed
a statistically significant benefit of pharmacist intervention in
comparison to the control group (RR = 0.86; [95% CI 0.80-0.94); P =
0.0005. The heterogeneity was insignificant (P = 0.72; I
= 0%). Patients receiving a pharmacist intervention
were 14% less likely for ADE than those who did not receive a
pharmacist intervention. The estimated number of patients needed to
prevent one ADE across all patient locations was 33. For PADEs, the
pooled results did not show a statistically significant benefit for
pharmacist intervention in comparison to the control group (RR = 0.79;
[95% CI 0.47 – 1.32]; P =0.37.There was substantial heterogeneity
in the pooled studies (P = 0.01; I = 77%). However,
there was a statistically significant subgroup difference (P = 0.005)
for the intervention type. Conclusions: To our knowledge, this
is the first systematic review and meta-analysis of RCTs seeking to
understand the association of pharmacist interventions with ADEs and
PADEs. The risk of having an ADE is reduced by a seventh for patients
receiving a pharmacist care intervention versus no such intervention.
This fraction could be higher for certain high-risk patients. The
estimated number of patients needed to be followed across all patient
locations to prevent one preventable ADE across all patient locations is
33. Also, a subgroup analysis of pharmacist intervention focus suggests
that further research is necessary to fully understand the impact of TOC
pharmacist intervention on PADEs. If validated, these findings have
potential to significantly reduce drug-related morbidity and related
healthcare costs.

Authors: Kumar Amit , Prasad Akhilesh , Jain Pankaj
Published: May 2024

The main objective of the paper is to generalize and enrich the Weyl transform
by introducing the Weyl correspondence in the linear canonical transform
(LCT) domain. In this paper, we propose the linear canonical-Wigner
transform in harmonic analysis of phase space along with the admissible
Wigner-Ville distribution (WVD) and Weyl transform in the LCT domain and
discuss some useful results. Further we establish the relationship between
the Wigner-Ville distribution and the Weyl transform in the LCT domain.

Sodium-glucose co-transporter 2 (SGLT2) inhibitor, an efficacious anti-diabetic agent, which has cardiovascular and renal benefits, can promote pancreatic β-cell regeneration in type 2 diabetic mice. However, the underlying mechanism remains unclear. In this study, we aimed to use multi-omics to identify the mediators involved in β-cell regeneration induced by dapagliflozin. We showed that dapagliflozin lowered blood glucose level, upregulated plasma insulin level, and increased islet area in db/db mice. Dapagliflozin reshaped gut microbiota, and modulated microbiotic and plasmatic metabolites related to tryptophan metabolism, especially L-tryptophan, in the diabetic mice. Notably, L-tryptophan upregulated the mRNA level of GLP-1 production-related genes (Gcg and Pcsk1) expression and promoted GLP-1 secretion in cultured mouse intestinal L-cells, and it increased supernatant insulin level in primary human islets, which was eliminated by GPR142 antagonist. Transplantation of fecal microbiota from dapagliflozin-treated mice, supplementation of L-tryptophan or treatment with dapagliflozin upregulated L-tryptophan, GLP-1, and insulin or C-peptide level, and promoted β-cell regeneration in db/db mice. Addition of exendin 9-39, a GLP-1 receptor (GLP-1R) antagonist, or pancreatic Glp1r knockout diminished these beneficial effects. In summary, treatment with dapagliflozin in type 2 diabetic mice promotes β-cell regeneration by upregulating GLP-1 production, which is mediated via gut microbiota and tryptophan metabolism.

We report the fabrication of metal alloy Au–Pd nanoparticles on semiconductor thin film substrates (ZnO) by laser-induced dewetting. Employing a UV excimer laser, a single pulse was directed onto a three-layer film stack on a glass substrate: glass/ZnO/Au/Pd and glass/ZnO/Pd/Au. We simulated the temperature attained by the thin films enabling the prediction of energy thresholds required for melting the metal films but avoiding modifying the ZnO film. A specific range is reported of the pulse energy conducive to nanoparticle formation and the energy threshold required to modify the ZnO film beneath them. Depending on the pulse energy applied, the mean diameter of the nanoparticles varied from approximately 150 to around 70 nm. Notably, higher fluences resulted in smaller particles but also induced surface cracks in the ZnO film. Additionally, we observed a reduction in nanoparticle size with increased Pd content. Our results show that laser-induced dewetting can produce bimetallic alloy nanoparticles and, at the same time, ensure the preservation of the optical properties of the ZnO film. This approach opens avenues for tailoring material characteristics and expanding the range of applications of metal nanoparticles on semiconductor-based systems.

Published: May 2024

En los países en desarrollo, el emprendimiento emerge como una alternativa vital ante el desempleo, aunque para ello se requiere el desarrollo de habilidades emprendedoras durante la etapa universitaria, ya que esto eleva significativamente las posibilidades de éxito en el momento en que se decide establecer un negocio propio. Sin embargo, en el contexto del empleo juvenil, la falta de experiencia o deficiencias en habilidades para emprender pueden obstaculizar la continuidad de nuevos proyectos empresariales. Esta investigación, por tanto, tiene como objetivo principal determinar el nivel de adquisición de competencias emprendedoras en estudiantes de una universidad pública que se encuentran en el último año de licenciatura en negocios y que participan activamente en iniciativas institucionales para fomentar el emprendimiento. Asimismo, se busca identificar posibles disparidades de género y diferencias entre aquellos con antecedentes previos en emprendimiento. Mediante un enfoque de muestreo no probabilístico, se recopilaron datos de 210 estudiantes a través de una encuesta en línea. Luego, se empleó un análisis de conglomerados utilizando una metodología de dos pasos, lo que permitió identificar cinco conglomerados que fueron posteriormente evaluados en su estructura mediante un análisis de varianza (ANOVA). Los resultados principales revelaron que en el ámbito de la educación superior pública, se ha promovido activamente el enfoque en el emprendimiento, lo que ha facilitado la adquisición efectiva de competencias profesionales, metodológicas, comunicativas, personales y de trabajo en equipo en la mayoría de los estudiantes. Además, se observó que los participantes de género masculino y aquellos con experiencia previa en el desarrollo de negocios mostraron un mayor nivel de adquisición de competencias emprendedoras. En consecuencia, esta investigación sugiere la necesidad de ajustes en los planes de estudio universitarios para incorporar contenidos que promuevan la identificación, desarrollo y aplicación de oportunidades de negocio, de modo que se promueva la inserción laboral de los graduados tanto en emprendimientos propios como en empleos asalariados.
The Coefficient of Emotiveness of «Mother Tongue» in the Context of Measuring the Symbolic Power of Minority Languages in the Russian Federation (Based on the Russian Census Data from 2010 to 2020)
Authors: Ханова Айгуль Филусовна , Больгина Татьяна Александровна , Драгой Ольга Викторовна
Published: May 2024

Исследуется особенность языковой ситуации РФ, при которой в социологических опросах и переписях населения респонденты указывают язык, которым они не владеют, родным. Данный феномен характеризует эмотивность родного языка и его особый символический статус, тесно связанный с этнической идентичностью. Вводится новый термин «коэффициент эмотивности», который определяет количественное соотношение людей, не владеющих, но указывающих язык в качестве родного. Усиление символического статуса языка и актуализация этнической идентичности тесно связаны с происходящими общественно-политическими событиями. Основной гипотезой исследования стало предположение о том, что языковой конфликт 2017–2018 гг. оказал влияние на коэффициент эмотивности миноритарных языков РФ. Проведенный статистический анализ с использованием линейной модели со смешанными эффектами на материале Всероссийской переписи населения 2010 и 2020 гг. показал значимый положительный рост коэффициента эмотивности в 2020 г. Результаты исследования подтвердили влияние общественно-политических событий 2017–2020 гг. на подвижность конструкта этнической идентичности и связанной с ней символической мощности миноритарных языков РФ.

This study examines a linguistic situation in Russia, focusing in particular on the phenomenon of respondents in sociological surveys and Russian censuses reporting the language they do not actually speak as their mother tongue. This phenomenon emphasizes the emotional significance of the Russian term ‘mother tongue’ and its unique symbolic status. The authors introduce a new term, the ‘coefficient of emotiveness,’ which quantitatively measures the proportion of people who do not speak the language but describe it as their mother tongue. At the same time, the strengthening of ethnic identity and the increasing importance of a language as a symbol are influenced by socio-political changes. The study’s main hypothesis is that the language conflict of 2017–2018 impacted the emotional significance of minority languages in the Russian Federation. A linear mixed-effects model based on the 2010 and 2020 Russian census data revealed a significant positive increase in the coefficient of emotiveness in 2020. Our research confirms that the 2017-2020 socio-political context influenced the ethnic identity and symbolic meaning of minority languages in Russia

Balancing the Load and Scheduling the Tasks using Zebra Optimizer in IoT based Cloud Computing for Big-data Applications.
Authors: Vijayaraj V. , Balamurugan M. , Oberoi M.
Published: May 2024

Task scheduling is one of the major problems with Internet of Things (IoT) cloud computing. The need for cloud storage has skyrocketed due to recent advancements in IoT-based technology. Sophisticated planning approaches are needed to load the IoT services onto cloud resources professionally while meeting application necessities. This is significant because, in order to optimise resource utilisation and reduce waiting times, several procedures must be properly configured on various virtual machines. Because of the diverse nature of IoT, scheduling various IoT application activities in a cloud-based computing architecture can be challenging. Fog cloud computing is projected for the integration of fog besides cloud networks to address these expectations, given the proliferation of IoT sensors and the requirement for fast and dependable information access. Given the complexity of job scheduling, it can be difficult to determine the best course of action, particularly for big data systems. The behaviour of zebras in the wild serves as the primary basis of stimulus for the development of the Zebra Optimisation Algorithm (ZOA), a novel bio-inspired metaheuristic procedure presented in this study. ZOA mimics zebras' feeding habits and their defence mechanisms against predators. Various activities are analysed and processed using an optimised scheduling model based on ZOA to minimise energy expenditures and end-to-end delay. To reduce makespan and increase resource consumption, the technique uses a multi-objective strategy. By using a regional exploratory search strategy, the optimisation algorithm may better utilise data and stays out of local optimisation ruts. The analysis revealed that the suggested ZOA outperformed other well-known algorithms. It was advantageous for big data task scheduling scenarios since it converged more quickly than other techniques. It also produced improvements of 18.43% in several outcomes, including resource utilisation, energy consumption, and make span.
Toward Peaceful Dialogues; Sunni, Shi’a and Ahmadiya
Authors: Barsihannor Barsihannor
Published: May 2024

The violence due to theological issues, especially as experienced by Shi’a and Ahmadiya in Indonesia suggests that religious sensitivity in a modern and democratic society is still a latent danger for the emergence of theological conflict in Muslim society. Even though they are in the same house (Islam) and referring to the same holy book, however, the reality shows that horizontal conflicts due to theological interest still occur and even pose a threat to religious life. Theological reasons are used as arguments to terrorize, attack, and eliminate other groups who are regarded differently. This research intends to reveal the common ground of the three theological schools, the impact of theological conflict, and to describe the role of the Indonesian government and society to create a conducive atmosphere in religious life.

Published: May 2024

In the domains of geological study, natural resource exploitation, geological hazards, sustainable development, and environmental management, lithological mapping holds significant importance. Conventional approaches to lithological mapping sometimes entail considerable effort and difficulties, especially in geographically isolated or inaccessible regions. Incorporating geological surveys and satellite data is a powerful approach that can be effectively employed for lithological mapping. During this process, contemporary RS-enhancing methodologies demonstrate a remarkable proficiency in identifying complex patterns and attributes within the data, hence facilitating the classification of diverse lithological entities. The primary objective of this study is to ascertain the lithological units present in the western section of the Sohag region. This objective will be achieved by integrated Landsat ETM+ satellite imagery and field observations. To achieve our objectives, we employed many methodologies, including the true and false color composition (FCC&TCC), the minimal noise fraction (MNF), principal component analysis (PCA), decoration stretch (DS), and independent component analysis (ICA). Our findings from the field investigation and the data presented offer compelling evidence that the distinct lithological units can be effectively distinguished. A recently introduced geology map has been incorporated within the research area. The sequence of formations depicted in this map is as follows: Thebes, Drunka, Katkut, Abu Retag, Issawia, Armant, Qena, Abbassia, and Dandara. Implementing this integrated technique enhances our comprehension of geological units and their impacts on urban development in the area. Based on the new geologic map of the study area, geologists can improve urban development in the regions by detecting building materials “aggregates”. This underscores the significance and potential of our research in the context of urban development.

Published: May 2024

Ports are some of the most significant entry points for Greek tourism investments and can be characterized as “development tools” for the country, both at the local and national level. The blue economy is a recent example of economic development, globally promoted as a way to achieve sustainability in maritime and coastal areas. Linaria Port has been accredited by the United Nations as a “The blue port with a shade of green,” constituting an environmentally sustainable community capable of promoting responsible environmental behavior both within the local community and among tourists. The port has been highly competitive in achieving high sustainability standards and mainly operates in ways that complement environmental quality. It has presented innovative, competitive, and sustainable solutions since 2010. This research aimed to collect primary and secondary data on tourist preferences to evaluate these services. Evaluation was conducted through anonymous questionnaires divided into two parts: the first part concerned the tourist profile, and the second part concerned tourists’ opinions on the services and facilities of the Port and the island. In the evaluation of the port, 91% of respondents rated the marina positively compared to other ports in the country, while 77% ranked the port of Skyros in a good position compared to other European or international ports. The overall quality of the tourist product was positively evaluated at 89%, while 90% of visitors were generally satisfied with the overall services offered. Moreover, 95% would return to Skyros within the next years.
Análise da produção e do desenvolvimento municipal da agropecuária tocantinense entre 2006 e 2017
Authors: Silva Cínthia Santos , Alves Lucir Reinaldo
Published: May 2024

A ascensão do cerrado na produção agropecuária colocou em foco o estado do Tocantins. Ele é o estado mais novo do Brasil, foi criado a partir da Constituição de 1988 e vem passando por um processo de expansão da sua estrutura produtiva. Entre 2006 e 2017, o Tocantins mais que quadriplicou seu valor bruto na produção agropecuária (VBPA). Assim, o objetivo desse trabalho foi analisar a localização e especialização do setor agropecuário tocantinense frente à região Norte, bem como verificar a associação entre o valor de produção do setor com o desenvolvimento dos municípios do Tocantins nos anos de 2006 e 2017. Para atender o objetivo foram aplicados os indicadores locacionais e de especialização, e as técnicas de Análise Exploratória de Dados Espaciais (AEDE). Os resultados mostraram que houve um aumento significativo na produção de lavouras temporárias, e uma desconcentração espacial do VBPA no estado. O AEDE apontou que, mesmo com o avanço do VBPA, muitos municípios com alto valor de produção estão cercados por municípios com baixo desenvolvimento, principalmente no indicador da saúde, que apresentou vários outliers alto-baixo.

Ochaechulla spinturniciformis, a new genus and species of mite in the family Laelapidae (Acari: Mesostigmata) from Slovakia
Authors: Mašán Peter , Halliday Bruce
Published: May 2024

We describe a new genus in the mite family Laelapidae from Slovakia, Ochaechulla gen. nov., to accommodate a new species, Ochaechulla spinturniciformis sp. nov., based on females collected from under loose tree bark that probably served as a bat roost. The new genus is characterized by a specific idiosomal setation with the loss of some setae on the dorsal shield and opisthogastric region, hypotrichy of the legs, an unusual arrangement of the ventral shields and legs on the idiosoma, and strongly shortened peritremes. Its thick dorsal setae, modified body shape, and strong reddish-brown sclerotization most closely resemble the ectoparasites of small mammals in the genus Laelaps C. L. Koch, although its unique combination of features clearly distinguishes it from them and any other dermanyssoids. The radial arrangement of the legs around the margin of the idiosoma is similar to the genus Spinturnix von Heyden.

Authors: Zhang Xiaoni , Lu Hongtao
Published: May 2024

This study presents a novel approach to the application of distributed logistic modeling for the enhancement of education and teaching in colleges and universities, particularly focusing on the pedagogical goals and curriculum content. Utilizing the abundance and accessibility of educational resources, this research harnesses data from diverse sources such as books, textbooks, catechisms, and blogs. Through the application of text mining and text recognition technologies, preliminary data are extracted for analysis. Subsequent data preprocessing steps involve the removal of extraneous information, null values, and outliers to refine the dataset. The research identifies key determinants influencing educational outcomes, establishing independent and dependent variables for these factors. The logistic and sigmoid functions are employed to compute the loss function, thereby addressing issues related to overfitting. Regularization transformations further optimize the results, culminating in the development of a robust distributed logistic model for education. An illustrative analysis demonstrates the model’s applicability and effectiveness in understanding and improving educational practices. Data presentation: P=0.026<0.05, the independent variable of knowledge base level (x7
) has a significant effect on the effect of education and teaching and OR-Value=3.11, that is to say, if the knowledge base level rises by one unit, the dependent variable of the impact of education and teaching will be increased by 3.11 magnitude of change.
Characteristic analysis of village cultural landscape by Lian Li space information technology and three-dimensional modelling
Authors: Lai Yanlin , Wang Hongyan
Published: May 2024

At present, due to the traditional village landscape protection method being relatively single, resulting in the traditional village landscape tends to “homogenization,” which is not conducive to the development of the village cultural landscape. This paper combines spatial information technology and three-dimensional modeling to reconstruct the village landscape and analyze its characteristics. Low-altitude oblique photography technology is used to collect village landscape information from multiple angles and then combined with the 3D model imaging law covariance equations to form the landscape 3D model features and then complete the multi-visual 3D model information matching. Finally, through texture mapping, the 3D model is generated to match the color of the real landscape. Using BIM technology, the data is refined to address the problem of local defects in the landscape 3D reconstruction process. The proposed technology is applied in practice to analyze the spatial comprehensibility of the test village landscape, and the comprehensibility value R² is obtained as 0.317, which is a poor spatial order of the test village. The village residents’ actual landscape color perception of the town ranges from -0.0364 to 0.4566, and the expected range is above 0.7. The actual perception is much lower than the predicted perception, and the subsequent landscape modification should be close to the villagers’ expectations.
Inertial Estimation in Power Grids Considering Load Contribution Based on FF-UKF
Authors: Li Shichun , Wang Xiaoyu , Wang Lijun , Su Lingjie , Luo Linhua
Published: May 2024

In modern power systems, the extensive integration of renewable energy sources leads to a reduction in system inertia, thereby affecting grid stability. This study proposes a novel method for estimating grid inertia, which, under quasi-steady state conditions, effectively incorporates load contribution by combining class noise signals collected by PMUs (Phasor Measurement Units) with the Forgetting Factor Unscented Kalman Filter algorithm (FF-UKF). The research initially analyzes the characteristics of various inertia sources in power systems dominated by renewable energy. Building on this, we propose a grid node equivalent inertia estimation model based on node equivalent frequency response, developing an FF-UKF-based algorithm that allows for the continuous dynamic estimation of inertia at various grid nodes. Simulation experiments conducted within the IEEE 39 bus system validate the method’s effectiveness and demonstrate the spatiotemporal distribution of grid inertia under varying levels of renewable energy penetration. This study is significant for understanding and enhancing frequency control and stability in power systems, providing key technical support for the modernization of the power system and the efficient integration of renewable energy.

Authors: Bruel Betina Ortiz , Romano Cezar Augusto , Gadda Tatiana Maria Cecy
Published: May 2024

Objective: Investigate the Corporate Social Investment (CSP) in the environment in Brazil, focusing on the UN's Sustainable Development Goal (SDG) 6 – Water and Sanitation.
 
Theoretical Framework: Achieving SDG 6 in Brazil requires partnerships between governments, companies and citizens to guarantee water resources for future generations, and the CSP can contribute in this aspect.
 
Method: Documentary research on BISC Reports (Benchmarking em Investimento Social Corporativo) from 2008 to 2023; GIFE Censuses (Grupo de Institutos, Fundações e Empresas) from 2005 to 2022-2023; and Sustainability Reports of participating companies.
 
Results and Discussion: In BISC surveys, CSP in the environment had a better moment in 2012, representing 12% of investments, when it decreased continuously until 2020, reaching 0.1%, and rising to 5.8% in 2022. Environment prevailed in companies' mandatory socio-environmental applications, meaning legally imposed investments to compensate for environmental impacts. In the GIFE censuses, the average number of companies with CSP in the environment was 42%, but the volume of resources in 2022 was only 5.8% of the total. Only 10 companies had an CSP related to SDG 6, with target 6.6, about protection and restoration of water-related ecosystems, having the greatest performance.
 
Research Implications: The private sector is a large consumer of potable water and the growing demand for water security requires new forms of corporate water management, beyond company walls and legal impositions.
 
Originality/Value: The CSP in the environment in Brazil is still not very representative, but there are success stories to be studied and made a reference for other companies.
Online Impulsive Buying Behavior of Mobile Site Shoppers in Turkey: A Mediation Analysis
Authors: Karahan Mehmet Ozan
Published: May 2024

Objective: The study investigates the correlation between mobile site quality (MSQ) factors and perceived enjoyment. It also explores the link between perceived enjoyment and both electronic word-of-mouth (eWOM) and online impulsive buying behavior of mobile site shoppers in Turkey.
 
Theoretical Framework: The theoretical framework considers MSQ factors (contact, responsiveness, efficiency, fulfillment, and privacy), perceived enjoyment, eWOM and online impulsive buying behavior.
 
Method: This study employs a quantitative methodology, utilizing a questionnaire as the primary data collection tool, designed for a sample size of 676 individuals fromTurkey selected through Purposive Sampling technique. The data analysis method employed is Structural Equation Modeling (SEM), utilizing the AMOS software to assess the goodness of fit statistics of the measurement model with the empirical data.
 
Results and Discussion: The results showed that the contact, efficieny, and the privacy of mobile site influence perceived enjoyment positively. Perceived enjoyment influences both eWOM and online impulsive buying behavior positively and finally eWOM influences online impulsive purchasing behavior positively as well.
 
Research Implications: The results suggest that improvements in MSQ factors of the contact, efficieny, and the privacy can provide mobile site shoppers more enjoyment and while perceived enjoyment has been increasing the probability of mobile site shoppers’ impulsive buying behavior, it also provides more effective marketing campaigns with less costs for the mobile retailers in Turkey.
 
Originality/Value: This study makes a significant contribution to the existing online impulsive behavior literature by focusing on the MSQ elements of mobile shopping sites among shoppers in Turkey. It examines the mediation of perceived enjoyment between all MSQ elements and online impulsive buying behavior, as well as eWOM between perceived enjoyment and online impulsive buying behavior, which have not been extensively explored in prior research.

Objective: To investigate the efficacy of plant growth-promoting rhizobacteria (PGPR) in enhancing the early development stages of Schizolobium parahyba, a critical species for the timber industry, aiming to optimize reforestation and agroforestry practices for sustainable forestry.
 
Theoretical Framework: The research is grounded in the exploration of symbiotic relationships between PGPR strains and plant species, focusing on their potential to improve seed germination, plant growth, and biomass production. The study examines how these interactions can be leveraged to enhance agricultural productivity and sustainability, with a specific emphasis on the benefits of employing PGPR in forestry.
 
Method: The study utilized an experimental approach, assessing the impact of four PGPR strains (Serratia marcescens, Pseudomonas protegens, Enterobacter absuriae, and Acinetobacter calcoaceticus) on S. parahyba seedlings. These were cultivated in three different substrates, with variables such as germination rate, above-ground and root growth, and biomass production meticulously measured to evaluate the effects of bacterial inoculation.
 
Results and Conclusions: The application of PGPR notably improved all measured growth parameters in S. parahyba seedlings, with A. calcoaceticus and P. protegens specifically enhancing stem and root development, respectively. A synergistic effect was observed in substrates containing peat, underscoring the significant potential of PGPR in boosting the productivity and sustainability of early-stage forestry cultivation. The findings advocate for further field studies to fine-tune these interactions, aiming to establish more resilient and ecologically sustainable agricultural practices.
 
Originality/Value: This research contributes novel insights into the utilization of PGPR in forestry, highlighting its substantial promise in enhancing the early growth stages of Schizolobium parahyba. By demonstrating the specific benefits of PGPR strains and their interactions with different substrates, the study offers a promising strategy for improving the sustainability and productivity of reforestation and agroforestry efforts.

Kitosan ve Organik Asitli Çözeltilerinin Mısır Silajı Kalitesine Etkileri
Authors: Sırakaya Selim
Published: May 2024

Silaj grubu yemlerin, belirli kalite standartlarında muhafaza edilmeleri noktasında, bazen katkı maddesi kullanımı önemlidir. Bu çalışma kapsamında, non-toksik, antimikrobiyal, antifungal ve biyobozunur özeliklere sahip kitosan ve kitosanın asetik ve laktik asitle hazırlanan jelatinize çözeltilerinin, mısır silajında katkı olarak kullanım potansiyelinin araştırılması amaçlanmıştır. Kitosan ve organik asitli çözeltileri, mısır silajına iki farklı biçimde uygulanmıştır. Mısır silajına, %0,5 - %1,0 ve %2,0 oranlarında kitosan karıştırılmış ayrıca %2’lik asetik ve laktik asit çözeltilerine, %0,0 - %1,0 ve %2.0 kitosan ilave edilerek hazırlanan jelatinize karışımlar, %10 oranında mısır silajına püskürtülmüştür. Kitosanlı gruplarda, ham protein (HP), toplam sindirilebilir besinler (TSB) ve enerji değerleri (ME, NEL, NEM, NEG), diğer gruplara oranla yüksek bulunmuştur. NDF ve ADF’de çözünmeyen kalıntıların HP değerleri (NDICP, ADICP), %2,0 kitosanlı grupta daha yüksek bulunmuştur. Nispi yem değeri (NYD), kitosanlı gruplarda yüksek bulunmuştur. Besin maddeleri tüm gruplar arasında değişkenlik göstermiş, fakat değişkenliklerin gruplar arasındaki kolerasyonu uyumlu bulunmamıştır. Amonyak azotu (NH3-N) en fazla %2,0 kitosan grubunda görülmüştür. Bütirik asit sadece kitosanlı gruplarda tespit edilmiştir. Laktik, asetik ve propiyonik asit miktarları gruplar arasında farklılık göstermiş fakat bu farklılıklar katkı uygulama oranları nispetinde olmadığı belirlenmiştir. Küf sadece kontrol grubunda tespit edilmiş, uygulama gruplarında ise görülmemiştir. Laktik asit bakterileri (LAB) uygulama gruplarında, kontrol grubuna oranla daha az bulunmuş ve en az %2,0 kitosan grubunda görülmüştür. Enterobakteri grubu mikroorganizmalar uygulama gruplarında tespit edilmemiştir. Maya en fazla kitosanlı gruplarda görülmüştür. Sonuç olarak kitosan ve kitosanlı çözeltiler, bazı parametrelerde olumlu değişimlere sebep olsa da genel olarak fermantatif ve mikrobiyoljik kalite bakımından istenilen düzeyde iyileştirme sağlamamıştır.
