The effect of pH on determination of activation energies and the optimum temperatures of hydrolysis of olive oil by lipase from porcine pancreas
Authors: Miłek Justyna
Published: February 2022

Purpose: The present paper reports the determination of the activation energies and the optimum temperatures of olive oil hydrolysis by porcine pancreas lipase with simultaneous effect of pH. Methods: The parameters were estimated based on the literature data on the activity curves versus temperature for olive oil hydrolysis by lipase obtained from porcine pancreas. It was assumed that both the hydrolysis reaction process and the deactivation process of lipase were first-order reactions by the enzyme concentration. A mathematical model describing the effect of temperature on porcine pancreas lipase activity was used. Results: The determinate activation energies Ea were from 31.37 ± 5.38 kJ/mol to 61.60 ± 11.46 kJ/mol, the optimum temperatures Topt were obtained in the range from 305.46 ± 1.26 K to 313.23 ± 1.18 K and the values of deactivation energies Ed were in the range from 65.18 ± 3.19 kJ/mol to 109.27 ± 6.79 kJ/mol. Conclusions: The obtained results (Ea, Ed, Topt) might find application in research on the prognosis of pancreatic cancer.

Purpose: In clinical practice, motor development in infants is assessed subjectively. Many researchers propose objective methods, which have numerous limitations, by attaching markers or sensors to the child’s limbs. The purpose of this study is to attempt to develop objectified numerical indices to describe the limb movements of infants without interfering with spontaneous activity. Methods: 20-minute video recordings of three infants’ movements who were purposively selected from 51 subjects were included in the study. The procedure of automatic calculation of head position time in 3 positions was applied. Movement features were determined to allow for the delineation of coefficients describing the movement in numerical values. Results: Presented parameters describe three infant’s movement aspects: quality (strength), distribution of postural tonus and asymmetry in relation to head position, described as four independent values. Estimated parameters variability over time was weighted up according to expert observations. The presented method is a direct reflection of infants' observation, currently performed by highly educated and experienced therapists. Conclusions: The interpretability and usefulness of the presented parameters were proved. All parameters estimation is fully automated. The conducted research is a prelude to future work related to creating an objective and repeatable tool, initially monitoring and ultimately supporting early diagnosis for differentiating normal and abnormal motor development.

Purpose: The aim of this work was the assessment of postural stability at different heights as well as in natural standing position and during tandem stance in female athletes who practice artistic gymnastics. Methods: The study comprised 34 athletes aged 8–12, practicing artistic gymnastics at a sports club „Korona Kraków”. The research tool was CQ-Stab 2P two-platform posturograph. The elevation was achieved using the Light SPL platform. The data were analyzed based on Wilcoxon signed-rank test and Spearman’s rank correlation. Results: The height at which the posturograph was set differentiated the path length of the statokinesiogram, both in the natural stance (p = 0.035) and tandem stance (p = 0.012). When the posturograph was placed on the floor, statistically significantly higher sway area delimited by the COP point (p < 0.001), statokinesiogram path length (p < 0.001), mean amplitude of COP displacement (p < 0.001) and mean frequency of COP displacement (p = 0.048) values were recorded in the tandem stance position. On the other hand, when the posturograph was placed on a landing, statistically significantly higher sway area delimited by the COP point (p < 0.001), statokinesiogram path length ( p < 0.001) and mean frequency of COP displacement (p < 0.001) values were recorded in the tandem stance position. Conclusions: Increasing height was accompanied by deterioration of stability indices. Postural stability improves with training experience.

Authors: Tijani Jed M. , Lipińska Patrycja , Ben Abderrahman Abderraouf
Published: February 2022

Purpose: This study aimed to characterize the 400 m freestyle pacing strategy, the effect of post-race feedback, and individualised race-pace training. Methods: Twenty male swimmers (13.4 ± 1.0 years) were randomly assigned into two groups. The experimental group used training monitoring based on intensities around 400 m pace (92 and 97% of 400 m speed), while, for the control group different heart rate zones (EN2 and EN2+) were used as an intensity criterion. The training volume was the same for both groups. A maximal 400 m freestyle simulated competition was performed before and after the 3 weeks period to determine intensities and to assess changes in performance. The rate of perceived exertion and heart rate values were also evaluated. Results: A fast start in the first 50–100 m, then a constant speed in the middle of the race and an end-spurt during the last 50–100 m was the pacing pattern adopted by the majority of the swimmers. Significant main effects of time were observed for 400 m time (p = 0.001; ES 3.39; very large). Results revealed significant pre-to-post improvements from 328 ± 26.3 s to 317 ± 19.4 s in the experimental group and from 329 ± 25.2 s to 321 ± 21.1 s in the control group. Conclusions: All the swimmers adopted almost the same parabolic pacing strategy before and after the training program with some differences in seconds that have made the strategy of the experimental group better balanced during the post-training test. Both training methods induced significant improvements in 400 m performance, to a greater extent for the training using intensities near 400 m race pace

This study was directed to deepen the effects of nutrient shortage on BCR/Ablprotein expression and signaling in chronic myeloid leukemia (CML) cells. The backbone of the study was cell culture in medium lacking glucose, the consumption of which we had previously shown to
drive BCR/Ablprotein suppression, and glutamine, the other main nutrient besides glucose. In this context, we focused on the role of lactate, the main by-product of glucose metabolism under conditions of rapid cell growth, in particular as a modulator of the maintenance of CML stem/progenitor
cell potential, a crucial determinant of disease course and relapse of disease. The results obtained indicated that lactate is a powerful surrogate of glucose to prevent the suppression of BCR/Abl signaling and is therefore capable to maintain BCR/Abl-dependent CML stem/progenitor cell potential.
A number of metabolism-related functional and phenotypical features of CML cells were also determined. Among these, we focused on the effect of lactate on oxygen consumption rate, the dependence of this effect on the cell surface lactate carrier MCT-1, and the relationship of the lactate effect
to pyruvate and to the activity of mitochondrial pyruvate carrier.

Published: February 2022

The purpose of the article is to examine the similarities and differences between transfer prices and customs values due to the importance of international trade. The transfer price is the price set in the transaction between two related companies if they operate from different countries or customs territories. In this case, the customs burden comes in between and impacts the prices. As price should be an arm’s length based on customs and transfer price perspective, some issues could arise as the rules are not identical from customs and transfer pricing perspective.
Littoral bioerosion, a tool for the study of sea level variations during the Holocene
Authors: Laborel J. , Deguen F. Laborel , Girard J. Collina , Morhange C.
Published: February 2022

Field study ofbioeroded littoral notches in several regions of the world was used to test the various values of bioerosion rates proposed in the literature. Data obtained, which are somewhat lower than values currently indicated, were used for suggesting answers to two pending questions in the history of the late Pleistocene and Holocene sea level rise. The first question involves the existence and duration ofstillstands during the Holocene transgression. Numerous littoral notches, produced by submersion at constant depths, allow us to propose that cumulative stillstand time may have been a few thousand years. This implies that stillstands were followed by episodes of very rapid sea level rise and that sea level curves are more stepped than is generally indicated by coral reef studies. The other problem involves the existence of fossil lines of elevated corals and vermetids along several tropical coasts (Brazil, west Africa, eastern Australia) which are currently explained by a slow hydro-isostatic rebound of the crust. The general weakness ofbioerosion on such elevated biogenic remains from Brazil­ian and west African shores, means that these remains were not submitted to mid-littoral bioerosion for long periods, i.e., that corresponding sea level fluc­tuations were too rapid to be explained by the hydro-isostatic rebound theory alone. They may instead have been caused by a combination of slow eustatic rise and/or hydro-isostatic rebound with rapid shifting of the sea surface, originating from fluctuations of geostrophic currents or water masses.

HAIR LOSS: CAUSES AND PATHOLOGY
Authors: Mahmood Mohammed D.
Published: February 2022

There are many diseases in which one of the main symptoms is hair loss. Hair loss in
medical terms is called "Alopecia". Many reasons can cause alopecia. Hair loss can be
due to nutritional factors, genetic problems, metals toxicity, and body inflammation.
Hormonal changes in the body can also lead to a loss of hair. Physiology and stages of
reproduction of hair in humans are also discussed. There are three stages in the process
of the hair reproduction cycle. Many factors can be responsible for the disruption of hair,
and stress is one of them. A hair pulling test should be done to check the quality of hair.
Doctors prescribe the medication and treatment according to the cause of the hair loss. If
the hair loss is due to nutritional changes, proper diet and supplements should be taken to
reduce the hair loss. A clinical evaluation of a patient with hair loss is important to
conclude. Doctors should keep themselves refreshed with the new advances in treatment.
Age factor is one of the primary reasons for hair color changes and hair loss.
Trichotillomania and traction alopecia are the two types of self-inflicted hair loss that
involve pulling the hair and heat, worsening hair condition using hair straighteners,
respectively.
A Pragmatic Study of Negation in English
Authors: Jameel Prof. Dr. Abdulkarim Fadhil , Jameel Prof. Dr. Abdulkarim Fadhil
Published: February 2022

This study is a qualitative analysis of the relation between pragmatics and negation in
English. The aim of the first part of the study is to examine the view that meaning can
originate from usage and negation can be analyzed within pragmatic point of view. And the
second aim is to examine the relation between presuppositions and negation and how
listeners can identify the target of negation. The first part of the study is a comparison
between two types of negation: descriptive and metalinguistic negation. The study shows that
descriptive negation is related to truth-functional meaning and its scope is narrow in contrast
to metalinguistic negation in which meaning is not merely a matter of truth-functional but
rather usage based. In addition, the scope of metalinguistic negation is wide and it scopes
over the whole utterance beyond the scope of the negative operator. The second part of the
study is to examine the relation between negation and presuppositions which are strictly
within the pragmatic aspects. The study also analyzes two presupposition properties:
cancellability and constancy under negation. The finding of the study is that presuppositions
are not canceled without negation, aren’t normally targeted by negation, and are canceled
when there is negation and additional material denying the presuppositional inference. For
constancy under negation test, the study shows that it cannot be applied all the time to
distinguish presuppositions from entailments.

Authors: ÖZDEMİR Halis , TURGUT Ezgi , KARCAALTİNCABA Deniz , BAYRAM Merih
Published: February 2022

Aim: Postpartum bleeding is one of the most important causes of maternal mortality. Herein, we attempted to predict hemoglobin (Hb) decrease by observing uterine artery doppler indices during the early postpartum period.

Materials and Method: The study was designed as a prospective cohort study. Pregnant women who visited Gazi University Hospital for normal vaginal delivery between 09/01/2018–09/01/2019 were included, and no risk factors were included.

Results: A total of 85 patients were included with the following parameters: average age at birth, 28.4 ± 4.6 years; average gestational age at birth, 38.83 ± 1.21 weeks. No significant correlation was observed among Hb, hematocrit (Htc), WBC, and other changes in PLT and mean uterine artery systole/diastole (S/D), resistance index (RI), and PI values. Furthermore, no statistically significant relationship was observed among uterus volume, mean uterine artery S/D, PI, and RI. Similarly, no significant relationship was observed among uterus volume, Hb, Htc, WBC, and PLT differences. Upon dividing primigravid and multigravida, the mean uterine artery PI median values did not differ according to the groups.

Conclusion: No correlation was observed between possible Hb decrease and resistance in the uterine artery. At the same time, other factors that may affect were evaluated (uterus dimensions, gravida, parity, whether there was membrane rupture, delivery times, lacerations during delivery, episiotomy, and birth weight) and no correlation was noted among these factors.
A Census of Protostellar Outflows in Nearby Molecular Clouds
Authors: Xu Duo , Offner Stella S. R. , Gutermuth Robert , Kong Shuo , Arce Hector G.
Published: February 2022

We adopt the deep learning method casi-3d (Convolutional Approach to Structure Identification-3D) to systemically identify protostellar outflows in 12CO and 13CO observations of the nearby molecular clouds, Ophiuchus, Taurus, Perseus, and Orion. The total outflow masses are 267 M
⊙, 795 M
⊙, 1305 M
⊙, and 6332 M
⊙ for Ophiuchus, Taurus, Perseus, and Orion, respectively. We show the outflow mass in each cloud is linearly proportional to the total number of young stellar objects. The estimated total 3D deprojected outflow energies are 9 × 1045 erg, 6 × 1046 erg, 1.2 × 1047 erg, and 6 × 1047 erg for Ophiuchus, Taurus, Perseus, and Orion, respectively. The energy associated with outflows is sufficient to offset turbulent dissipation at the current epoch for all four clouds. All clouds also exhibit a break point in the spatial power spectrum of the outflow prediction map, which likely corresponds to the typical outflow mass and energy injection scale.
The Dynamical Structure of the Outflows Driven by a Large-scale Magnetic Field
Authors: Li Jia-Wen , Cao Xinwu
Published: February 2022

A large-scale magnetic field is crucial in launching and collimating jets/outflows. It is found that the magnetic flux can be efficiently transported inward by a fast-moving corona above a thin disk. In this work, we investigate the dynamical structure of the outflows driven by the large-scale magnetic field advected by a hot corona. With the derived large-scale magnetic field, the outflow solution along every field line is obtained by solving a set of magneto-hydrodynamic equations self-consistently with boundary conditions at the upper surface of the corona. We find that the terminal speeds of the outflows driven from the inner region of the disk are ∼0.01–0.1c. The temperatures of the outflows at a large distance from the black hole are still as high as several ten keV. The properties of the magnetic outflows derived in this work are roughly consistent with the fast outflows detected in some luminous quasars and X-ray binaries (XRBs). The total mass-loss rate in the outflows from the corona is about 7%–12% of the mass-accretion rate of the disk. The three-dimensional field geometry, the velocity, temperature, and density of the outflows derived in this work can be used for calculating the emergent spectra and their polarization of the accretion disk/corona/outflow systems. Our results may help understand the features of the observed spectra of XRBs and active galactic nuclei.
Resolved Gaia Triples
Authors: Tokovinin Andrei
Published: February 2022

A sample of 392 low-mass hierarchical triple stellar systems within 100 pc resolved by Gaia as distinct sources is defined. Owing to the uniform selection, the sample is ideally suited to study unbiased statistics of wide triples. The median projected separations in their inner and outer pairs are 151 and 2569 au, respectively, and the median separation ratio is close to 15. Some triples appear in nonhierarchical configurations, and many are just above the dynamical stability limit. Internal motions in these systems are known with sufficient accuracy to determine the orbital motion sense of the outer and inner pairs and to reconstruct the eccentricity distributions. The mean inner and outer eccentricities are 0.66 ± 0.02 and 0.54 ± 0.02, respectively; the less eccentric outer orbits are explained by dynamical stability. The motion sense of the inner and outer pairs is almost uncorrelated, implying a mean mutual inclination of 83.°1 ± 4.°5. The median mass of the most massive component is 0.71 M
⊙, and the median system mass is 1.53 M
⊙. In a 0.69 fraction of the sample the primary belongs to the inner binary, while in the remaining systems it is the tertiary. A 0.21 fraction of the inner subsystems are twins with mass ratios >0.95. The median outer mass ratio is 0.41; it decreases mildly with increasing outer separation. Presumably, these wide hierarchies were formed by collapse and fragmentation of isolated cores in low-density environments and represent a small fraction of initial systems that avoided dynamical decay. Wide pre-main-sequence multiples in Taurus could be their progenitors.

Invasive alien species (IAS) continue to shape the global landscape through their effects on biological diversity and agricultural productivity. The effects are particularly pronounced in Sub-Saharan Africa, which has seen the arrival of many IAS in recent years. This has been attributed to porous borders, weak cross border biosecurity, and inadequate capacity to limit or stop invasions. Prediction and early detection of IAS, as well as mechanisms of containment and eradication, are needed in the fight against this global threat. Horizon scanning is an approach that enables gathering of information on risk and impact that can support IAS management. A study was conducted in Ghana to establish two ranked lists of potential invasive alien plant pest species that could be harmful to agriculture, forestry, and the environment, and to rank them according to their potential threat. The ultimate objective was to enable prioritization of actions including pest risk analysis, prevention, surveillance and contingency plans. Prioritisation was carried out using an adapted version of horizon scanning and consensus methods developed for ranking IAS worldwide. Following a horizon scan of invasive alien species not yet officially present in Ghana, a total of 110 arthropod and 64 pathogenic species were assessed through a simplified pest risk assessment. Sixteen species, of which 14 were arthropods and two pathogens, had not been recorded on the African continent at the time of assessment. The species recorded in Africa included 19 arthropod and 46 pathogenic species which were already recorded in the neighbouring countries of Burkina Faso, Côte d’Ivoire, and Togo. The majority of arthropod species were likely to arrive as contaminants on commodities, followed by a sizable number which were likely to arrive as stowaways, while some species were capable of long distance dispersal unaided. The main actions suggested for species that scored highly included full pest risk analyses and, for species recorded in neighbouring countries, surveys to determine their presence in Ghana were recommended.

Published: February 2022

Notre recherche propose d’approfondir l’étude de la RSE en PME sous le prisme individuel, en adoptant le cadre conceptuel des microfondations, qui met en avant le rôle fondamental des représentations du dirigeant dans le déploiement de la RSE en PME. Nous nous intéressons aux liens entre représentations et pratiques RSE à l’égard des employés, à travers un objet très illustratif des préoccupations des dirigeants en matière de RSE : le bien-être des salariés. Notre méthodologie nous permet d’identifier une typologie des représentations des dirigeants en matière de bien-être en trois classes qui correspond à des pratiques sociales et ressources humaines différenciées : représentation relationnelle, représentation fonctionnaliste et représentation holistique du bien-être. Ces trois visions différenciées du bien-être sont caractérisées par un engagement plus ou moins proactif du dirigeant et une préoccupation plus ou moins importante à l’égard du salarié.
Accompagnement d’une famille migrante en Guyane

Published: February 2022

Si la migration fait vaciller les repères identitaires du sujet, le contexte de domination sociale et de rejet amplifie son désarroi. Cette situation est amplifiée lorsque les institutions du travail social interviennent dans la sphère familiale. Cet article s’intéresse à ce type de contexte en se penchant sur le cheminement d’une famille étrangère dont le bébé a été retiré sans ménagement pour être confié à l’Aide Sociale à l’Enfance et avec qui les relations se présentaient sous le signe du malentendu. Vivant le placement de leur enfant comme un rapt et se sentant menacés par les intervenants, les parents refusaient leur présence. Il a fallu modifier la prise en charge, l’adapter, pour que ces parents parviennent à se l’approprier. C’est en leur donnant la possibilité d’utiliser des lieux et des moments qui les sécurisaient qu’un véritable travail de soutien a pu voir le jour. Ainsi, il apparaît parfois nécessaire de réinventer le cadre, pour que les familles puissent pleinement se saisir d’une offre d’accompagnement trop souvent vécue comme intrusive et inquiétante.
La correction des devoirs à la maison : une recherche ethnographique avec des mères et des enfants en Italie
Authors: Bolognesi Ivana , Dalledonne Vandini Chiara
Published: February 2022

L’article porte sur la question des devoirs à la maison à partir de l’analyse d’interactions entre des enfants fréquentant l’école primaire et leur mère, lors de la correction des devoirs. L’objectif est d’identifier les modes de communication et les pratiques récurrentes adoptés par les parents pour soutenir les enfants dans cette activité. La recherche, à caractère ethnographique, utilise l’analyse du discours à partir de transcriptions d’un corpus vidéo qui a permis l’identification des échanges à travers lesquels parents et enfants construisent la correction du devoir. La manière dont ces mères interagissent montre qu’elles connaissent la culture de l’école, les langages disciplinaires et ses artefacts et, donc, qu’elles semblent toutes correspondre à l’idée d’un parent institutionnellement compétent.

Introduction:

Scrub encephalitis (SE) is one of the known causes of acute encephalitis syndrome (AES). Although central nervous system involvement is known in scrub typhus, its association with AES is less understood and lesser diagnosed. In the absence of a point of care test for scrub typhus, cases of SE can be easily missed. A clinical approach using detailed history and clinical profiling of SE will help to diagnose SE in our region, using minimum resources, within a reasonable period.

Aims:

To analyze the clinical spectrum in patients of SE and to evaluate the investigations required to diagnose SE.

Methodology:

This is a retrospective study that analyzed Scrub typhus patients over 2 years from January 2018 to December 2019. A total of 370 patients were screened and 23 patients who satisfied the study criteria were included in the study and analyzed.

Results:

Among the cases of scrub typhus admitted in the hospital, the prevalence of SE was 6%. The most common presenting complaint was fever in 21 patients (91%) followed by altered sensorium in 16 (70%) and seizures in 9 patients (39%). An eschar was noted in 66% of the cases. The mean Glasgow Coma scale was 11 among the cases with almost 70% of cases showing signs of meningeal irritation. Organ involvement was noted as thrombocytopenia in 21 patients (91%), 16 patients (69%) with jaundice, and 1 (4%) with acute kidney injury.

Conclusion:

SE is an AES which, if detected early, is easily treatable with no residual neurological sequelae. Hence, identification of this condition and prompt diagnosis of SE becomes crucial to the management of this complication of scrub typhus.

Over these previous years, clinicians dealing with patients with COVID infection 2019 have discovered that the abundant inflammatory response induced by the virus serves as a significant cause of the acute respiratory distress syndrome (ARDS) and multi-organ dysfunction, which happen in majority of the lethal cases. Presently, there is not a single drug available as an approved and genuine medication for corona infection, in this sphere of time immunomodulatory agents has exhibited encouraging response against coronavirus infection. The initial finding that interleukin-6 (IL-6) levels are raised in serious COVID-19 and independently foresee the risk of developing ARDS and finally death, such results had centered the clinical investigations on this pro-incendiary and pleiotropic cytokine. Tocilizumab (TCZ) is humanized anti-interleukin 6 receptor monoclonal immunizer and has been endorsed for different rheumatological ailments. Currently, many steroids as they act as an immunomodulatory agent have shown fantastic therapeutic effects while used in COVID infected peoples, such clinical data advocated the application of tocilizumab to combat corona infection. Patients who were in life threatening condition because of COVID-19 initiated pneumonia developed hyper aggravation. This medication lessens the further decay of the patient caused because of agglomeration of lymphocytic cells and diminishes the degree of high CRP (C-responsive protein). Nevertheless, several clinical investigations have been in progress to ascertain the drug profile. So that TCZ may be used in COVID patients with optimal effectiveness associated with minimum risk of adverse events. In this article, we have tried to encompass all relevant information about the pharmacology of TCZ, which will surely help to understand clinical behaviour of the drug.

-The next era in the advent of the internet is internet
based computing also known as cloud computing. It has been
the emphasis in recent years, but security concerns are one
among the most important impediments to the rise of cloud
computing.. It essentially sends user data and application
programs to massive data centers, i.e. a distant cloud, where
consumers have little control and data management may be
insecure. However, numerous security issues raised by the
cloud's unique nature must be addressed and fully
acknowledged.. Amongst the most critical concerns which
must be tackled is the security issue. Issues with data security
created by user data and software in the provider's
jurisdiction. Cloud users search for cloud resources with
secure data management. When sharing their personal data
over public clouds, some cloud users may prefer to manage
their data with more privacy. This document focuses on
improving privacy-related data security in the cloud and
related works that have been done to enhance data security in
cloud computing. This research review work analyzes and
discusses several of the security and privacy improvements
evaluated in related existing systems.

American foulbrood (AFB) is one of the most important contagious honey bee diseases. In Serbia, it is mandatory to report AFB, and this disease is registered in our country every year. Starting from 2018, active surveillance of the presence of the AFB has been conducted throughout the country. The paper analyzes the data on the occurrence of AFB during the period between 2019 and 2021 from official disease reports in the National Animal Disease Notification System "VetUp". The results of this research indicate that AFB appears every year in the Republic of Serbia, despite the measures that are being applied. The results indicate that in 36 settlements in the country, this disease has reoccurred in the same localities in the observed period. Namely, in 17 localities AFB occurred consecutively in the 2019-2020 period , while in 21 localities the disease was re-registered consecutively in the period between 2020 and 2021 (until 6.11.2021), and it reoccurred in 2021 in 9 localities, compared to the registered cases of AFB in 2019. It was found that the disease has consecutively been reoccurring in 5 location between 2019 and 2021 in the same locations. The fact that the disease has been occurring for several years in the same places speaks in favor of the fact that the control measures applied in the control of this disease are not effective enough. Continuing education of beekeepers, veterinarians and veterinary inspection in the field of diagnosis and effective decontamination and neutralization of all potencional sources of AFB reinfections, revision of current legislation, as well as raising awareness of the importance of early diagnosis of as many cases of this disease as possible are the key factors in successful AFB control.

The honey bee Apis mellifera is an important beneficial insect recognized by production of honeybee products, having an important role in agricultural production through pollination, and play an equally crucial role in conserving the biodiversity in many natural ecosystems. According to available literature data, in the last more than 20 years, dramatic honey bee winter colony losses have been reported frequently all over the world that could have a direct influence on human food resources and can affect not only apiculture or agriculture, but also has an anthropological threats. One among many reasons for global bees-decline phenomenon is the influence of many viruses on honeybees’ health. Until today, in total, 36 viruses is detected in honey bees, and for many of them still without known pathogenicity on honeybees’ health. However, it is well known that some of these viruses like Acute Bee Paralysis Virus (ABPV), Chronic Bee Paralysis Virus (CBPV), Deformed Wing Virus (DWV), Black Queen Cell Virus (BQCV), Sacbrood Virus (SBV), Kashmir Bee Virus (KBV), Israeli Acute Paralysis Virus (IAPV), Slow bee paralysis virus (SBPV), Varroa destructor virus (VDV1) and some others has direct or indirect influence on individual honeybee or on whole honeybees colony health. In this paper the review of existing literature data on the presence, prevalence and characterization of honeybee viruses detected in honeybee colonies and apiaries from different regions in Serbia from first detection of their presence in 1986 till nowadays is presented and discussed.

Land restoration is an effective nature-based solution for combating rural poverty and climate change across Latin America. But without well-designed public incentives that reward farmers and forest managers for protecting and growing trees, it will be difficult to achieve the region's food security, climate, forest conservation, and biodiversity goals. This issue brief evaluates the public incentives of six Latin American countries and calculates how much they pay farmers and other landholders that restore land.
