The Role of Institutional Design and Enabling Environmental: Collaborative Governance of a Pilgrimage Tourism, Indonesia
Authors: Musleh Moh. , Subianto Agus , Tamrin M. Husni , Bustami Mohammad Reevany
Published: April 2023

This article discusses the role of stakeholders from the descendants of Kings, who collaborated with the government and private sectors in managing of the pilgrimage tourism heritage site of the tomb of the Kings of Asta Tinggi, in Sumenep district. The purpose of this study was to investigate the various factors that influence stakeholder collaborations in the management of sustainable pilgrimage tourism and which stakeholder groups have a sustained traditional of authority. This qualitative research uses a case study approach and data collection through in-depth unstructured interviews and observations. This study seeks to take a new perspective in the analysis of the collaborative governance theory in the face of the social environment factor. The study results show that stakeholders, facilitative leadership, and enabling environmental factors become resources and strengths in the success of collaborative governance even though the role of private and government sectors are still limited. The findings reveal that stakeholders from the community, namely the traditional group as a companion of pilgrims, have an important role in collaboration, because they can only be replaced by the descendants, while the collaborative initiation comes from the community. We suggest the importance of government initiation to expand collaboration networks and facilitate the formation of the institutional administrator of Asta Tinggi site, through reconciliation which represents two descendants of Kings. The findings of this study are expected to enrich the theory of collaborative governance.

This work aims to adolescence self-mutilating has become a relevant topic. Psychoanalysis contributes significantly to studies about adolescents, studying behavior mechanisms in teens and pointing out solutions to the problem. In this way, since psychoanalysis emerged, this topic has been studied, and has been deepen studied nowadays. Therefore, this article proposes a study about the possible illnesses or unconscious mechanisms, which may be behind adolescents self-harm behaviors, and that can point out warning signs. This work presents adolescence and its transformations and makes a relationship between self-mutilation and hysteria, social contexts such as media, affective relationships and experienced traumas. It al so presents psychoanalytic interpretations on the subject. It is worth mentioning that psychoanalysis, in addition to investigating unconscious issues, also proposes an effective treatment by techniques created since the creation of this approach, improving itself with new contributions and presents how the various psychoanalytic authors contribute to the theme in question.

The article describes the formation and functioning of post-Soviet political systems in the light of the constitutional transformations taking place in them, which influenced their choice of the form of public administration and its subsequent transformation. Comparing the powers of the highest state bodies in the states under consideration, the authors came to the conclusion that Kyrgyzstan and Kazakhstan are presidential republics, while Turkmenistan, Tajikistan, Belarus, Azerbaijan and Uzbekistan are super-presidential republics with a wide range of powers of the head of state. Armenia and Georgia have chosen a parliamentary form of government, while Moldova and Ukraine are balancing between a parliamentary-presidential model, which is why the political systems of these states are quite unstable, the change of power in which often occurs unconstitutionally.

The impact of health education and public sanitation on the spread of COVID-19
Authors: Cheng Fang , Kang Xiaxia
Published: April 2023

In this paper, we formulate a deterministic mathematical model SEAIRB to
study the dynamics behavior of COVID-19 pandemic. The model incorporates
the impact of two strategies, health education and public sanitation, on
the spread of the epidemic. Firstly, by using Routh-Hurwitz criteria,
the disease-free equilibrium is locally asymptotically stable when the
basic reproduction number does not exceed 1. Further, by using the
comparison theorem, the global asymptotic stability of the disease-free
equilibrium is obtained. Finally, numerical simulations are performed to
verify the theoretical analysis and analyze the impact of different
control strategies on the spread of the epidemic.

Published: April 2023

Morocco has a long history of domesticating cannabis and refuges a local
Beldia population, which lacks detailed information on genetic
diversity. In this study, the genetic diversity of cannabis grown in
four Moroccan regions was assessed with six genomic SSR markers
involving two cannabis populations: the local Beldia and the introduced
Critical variety. A total of 111 alleles were detected, with an average
of 18.5 alleles /locus. Several genetic diversity indices were measured
for both populations and showed the superiority of Beldia with a high
genetic diversity compared to Critical. The analysis of molecular
variance showed that genetic variability was remarkably observed within
individuals (65%) and, to a less extent, within and among populations
(19% and 16%, respectively). Principle coordinates analysis, unrooted
neighbor-joining tree, and genetic structure profiles confirmed that
Beldia and Critical are genetically distant and belong to two different
gene pools. The gene flow revealed the presence of a genetic exchange
between the two populations, thus highlighting the need to protect the
local genetic heritage of Morocco from potential genetic erosion.

Published: April 2023

Objective: To evaluate the frequency and burden of disease of
SARS-CoV-2 and other respiratory viruses in children under the age of 2
months. Methods: A retrospective, cross-sectional,
single-center study was conducted between March 2021, and February 2022.
All children under the age of 2 months and tested for SARS-CoV-2 were
included. The frequency of SARS-CoV-2, of other respiratory viruses and
the burden of disease caused by SARS-CoV-2 and other respiratory viruses
were evaluated. Results: 727 children with an RT-PCR test for
SARS-CoV-2 were included (mean age: 0.9 months (±0.6); boys: 57%); 514
(71%) in the emergency room and 213 (29%) in hospital. Among them, 62
(8.5%) had a positive RT-PCR test for SARS-CoV-2, more often in the
Omicron period (23%) than in the Alpha period (4%). Of the 565 (78%)
with a multiplex RT-PCR test for other viruses, 325 (58%) were
positive. Children with a positive SARS-CoV-2 were less likely to have
required respiratory support (p=.001), enteral nutrition (p=.03), or
intensive care admission (p=.01) and had a shorter hospital stay than
children with other respiratory viruses (5d vs. 7d, p=.007).
Conclusion: In this young population of children, SARS-CoV-2
infection was less frequent and less severe than other viral respiratory
infections.
Dispersal ability reduces thermal specialization and prevents climate-driven extinctions in a Neotropical rainforest
Authors: Chaves Cleber , Carnaval Ana , Leal Barbara , Santos Jessie , Monteiro Erison Carlos , Silva Clarisse da
Published: April 2023

Dispersal ability is a key determinant of the realized species niche.
Yet, whether dispersal ability influences environmental specialization
and exerts a direct, indirect, or null effect on species’ tolerances is
still unclear. Here, we ask whether and how dispersal ability can shape
both the realized and fundamental niches. Focusing on plants,
invertebrates, and vertebrates of the topographically complex Atlantic
Rainforest, a top global biodiversity hotspot, we further evaluate how
dispersal ability correlates with species range shifts in response to
climate change. We find that high-dispersal species have broader thermal
tolerances relative to low-dispersal taxa. When projected in geographic
space, the data predict widespread upslope range shifts of the Atlantic
Rainforest biodiversity with the intensity and direction depending on
the species-specific trends depending on dispersal ability. These
upslope movements, in turn, may negatively impact the native communities
intrinsically associated with the Atlantic Forest mountaintops. Under
the warmest climate scenario predicted for the end of the 21st century,
the models project that those species with the lowest dispersal ability,
particularly low-dispersible ectotherms, will be the most impacted by
local extinctions. In turn, the wider thermal tolerance of
high-dispersible species will reduce shifts in their geographical range
due to climate change. Given the rapid rate of habitat conversion
experienced by this and other landscapes worldwide, we argue that the
smaller endurance of low-dispersible species to environmental changes
deserves special attention, as dispersal ability appears relevant for
biodiversity management in a warmer world, especially in threatened
species-rich regions such as this.
Effect of captopril on paraplegia caused by Spinal Cord Ischemia-Reperfusion Injury in rats
Authors: Kazemi Hossein , Hafezi Bahareh , Jafari Amir Moghadam
Published: April 2023

Objective: To determine whether captopril could prevent spinal
cord damage after induction of ischemia-reperfusion injury in rats.
Materials and Methods: We randomly divided 24 adult male Wistar
rats, weighing 230 - 350 g, into 4 groups (n= 6 in each group): Spinal
cord ischemia-reperfusion with captopril, spinal cord
ischemia-reperfusion, sham operated with captopril, and SHAM. 24 and 1.5
hours before ischemia induction, captopril was administered
intragastrically (100 mg/kg) to the SHAM+Cap and the SCI-R+Cap groups.
Abdominal aortic clamping was performed in the SCI-R and SCI-R+Cap
groups for 40 minutes. Hindlimb motor function was evaluated using the
Tarlov Scale at 4, 6, 12, 24, 48, and 60 hours after SCI. Biomarkers of
oxidative stress were measured to evaluate biological responses to
therapeutic interventions (MDA, FRAP and PAB assays). Results:
Throughout the study period, the SCI-R group had significantly lower
motor function scores than the other groups (P < 0.05). The
MDA and PAB levels were higher in the SCI-R group than in the SHAM group
(P < 0.05). The FRAP value was lower in the SCI-R group than
that in the SHAM group (P < 0.05). The SCI-R+Cap had higher
motor function scores than the SCI-R group at all time points (P
< 0.05). There were no notable differences in MDA
concentration, FRAP and PAB values between the SCI-R+Cap and the SCI-R
groups (P > 0.05). Conclusion: Captopril may act
as a protective agent against spinal cord ischemia-reperfusion injury in
rats based on hind limb motor function assessment.
Study on the Optimization Model of Ecological Compensation Criteria - Huaihe River as an Example
Authors: yuan shaohua
Published: April 2023

Watershed water ecology compensation, as a key technology to control and
restore the ecology of damaged watersheds, is widely used in many fields
such as water environmental protection, water environment development,
and watershed management. This paper optimizes the opportunity cost
method and water resources value method models based on occupancy
theory, regional economic level and allocation scheme, and analyzes the
results of the two models and the optimized scheme. The results show
that: (1) the opportunity cost method is more than 9 times larger than
the standard calculated by the water resource value method; (2) the
optimized model makes the distribution of payment and compensation
cities more reasonable. The optimized accounting of ecological
compensation standards improves the accuracy of the two models and
provides a reference for the construction of ecological compensation
standards system in the watershed in the future.

Published: April 2023

Restoring and preventing losses of the world’s forests are promising
natural pathways to mitigate climate change. In addition to regulating
atmospheric carbon dioxide concentrations, forests modify surface and
near-surface air temperatures through biophysical processes. In the
eastern United States (EUS), widespread reforestation during the 20th
century coincided with an anomalous lack of warming, raising the
question of whether reforestation contributed to biophysical cooling and
slowed local climate change. Using new cross-scale approaches and
multiple independent sources of data, our analysis uncovered links
between reforestation and the response of both surface and air
temperature in the EUS. Ground- and satellite-based observations showed
that EUS forests cool the land surface by 1-2 °C annually, with the
strongest cooling effect during midday in the growing season, when
cooling is 2 to 5 °C. Young forests aged 25-50 years have the strongest
cooling effect on surface temperature, which extends to the near-surface
air, with forests reducing midday air temperature by up to 1 °C. Our
analyses of historical land cover and air temperature trends showed that
the cooling benefits of reforestation extend across the landscape.
Locations predominantly surrounded by reforestation were up to 1 °C
cooler than neighboring locations that did not undergo land cover
change, and areas dominated by regrowing forests were associated with
cooling temperature trends in much of the EUS. Our work indicates that
reforestation contributed to the historically slow pace of warming in
the EUS, highlighting the potential for reforestation to provide local
climate adaptation benefits in temperate regions worldwide.
Contribution of fresh submarine groundwater discharge to the Gulf of Alaska
Authors: Russo Aeon , Boutt David F , Munk Lee Ann , Jenckes Jordan
Published: April 2023

High latitude mountain environments are experiencing disproportionately
adverse effects from climate change. The Gulf of Alaska (GoA) region is
an embodiment of this change, particularly concerning a shifting
hydrologic balance. Even so, the magnitude and contribution of fresh
submarine groundwater discharge (fresh SGD) remains virtually unexplored
within the region, though it has gained increasing attention globally
due to its chemical significance and influence on coastal ecosystems.
Here we provide the first regional estimates of fresh SGD to the GoA
using two established water balance approaches. This is an effective way
to distinguish the contribution of terrestrially derived fresh SGD,
rather than the more commonly quantified total SGD which includes
discharge that is driven by marine forces such as sea-level oscillations
and density gradients. We compare the approaches and assess their
capabilities in computing the magnitude of fresh SGD over a large
regional scale. Mean annual fresh SGD flux ranges between 26.5 to 86.8
km3 yr-1 to the GoA, equivalent to 3.5-11.4% of the total freshwater
discharge. Contributions are highest in the Southeastern panhandle and
lowest in the Cook Inlet basin, with the highest area normalized
contribution occurring in the Prince William Sound. Fresh SGD exhibits
high spatial and temporal variability throughout the region. Although
freshwater discharge to the GoA is investigated considerably, the
importance of fresh SGD has, thus far, been overlooked.
Spatiotemporal variability of extreme precipitation events and associated atmospheric processes over Dronning Maud Land, East Antarctica
Authors: Simon Sibin , Turner John , Thamban Meloth , Wille Jonathan , Deb Pranab
Published: April 2023

We investigate the spatial and temporal variability of extreme
precipitation events (EPEs) in the Dronning Maud Land (DML) sector of
Antarctica using high-resolution ECMWF ERA5 reanalysis data. This study
examines the spatial occurrence of EPEs across DML, focusing
particularly on six locations spanning the coastal and interior parts of
the area. The largest snowfall amounts are usually found on
eastward-facing slopes in the coastal zone. EPEs occur predominantly in
north-easterly to easterly flows, leading to enhanced precipitation on
the windward side of the orographic features with a steep gradient. Wind
during EPEs was found to be more directionally consistent in the coastal
area than in the interior. An east-west couplet of a mid-tropospheric
ridge and low-pressure center is essential for steering warm moist
maritime airmasses into the DML region before EPEs. Approximately 40%
of EPEs result from atmospheric rivers (ARs), narrow bands of moist air
originating at subtropical latitudes, which provide the greatest daily
precipitation amounts. From 1979 to 2018, much of the DML experienced a
statistically significant (p < 0.05) increase in the number of
EPEs per year, along with increased precipitation from the EPEs. These
trends were associated with significant changes in moisture availability
and poleward meridional winds in the Atlantic sector of the Southern
Ocean. The inter-annual variability in the number of EPEs is primarily
dictated by regional atmospheric variability, while the influence of the
Southern Oscillation Index and Southern Annular Mode is limited.

Impaired local hydrophobicity, structural stability and conformational flexibility due to point mutations in SULT1 family of enzymes
Authors: Ceauranu Silvana , Ostafe Vasile , Isvoran Adriana
Published: April 2023

Sulfotransferases (SULTs) are enzymes involved in phase II of the metabolism of xenobiotics. Single nucleotide polymorphisms were identified for genes encoding the SULTs leading to allozymes with modified sulfating activity. This study aims to analyse the effects of the most frequently identified amino acid mutations in the sequences of enzymes belonging to the SULT1 family on their local properties and structural stability. The outcomes reveal that single point mutations alter the local hydrophobicity and flexibility, mainly due to destabilization of the protein structures, may consequently lead to changes in the dynamic of the active site activity reducing the affinity for the substrate. Elucidation of how the single point mutations influence the activity of enzymes contributes to understanding the molecular basis of the specificity of enzymatic activity and mitigating anomalies in the metabolism of xenobiotics.

Authors: Eremeev Artem V. , Pikina Arina S. , Vladimirova Tatyana V. , Bogomazova Alexandra N.
Published: April 2023

Over the past decades, cell viability tests have been an essential research tool in cell biology, tissue engineering, and regenerative medicine. Assessment of cell viability is mandatory in the production and quality control of cell products for biomedical applications.
Methods of viability assessment can be broadly classified according to the underlying mechanism and how the results obtained are evaluated. This article presents variants of the most commonly used tests and protocols for assessing cell viability. Their advantages and disadvantages are presented, which should be considered when planning experiments, e.g., when developing cell preparations for regenerative medicine.
The authors point out the main factors influencing the choice of viability assessment method: efficiency, speed, safety, reproducibility, sample integrity, compatibility with biomaterial, and cell line type. Finally, the authors discuss separately cell viability tests that can be applied not only to 2D cell structures but also to 3D cell structures, which have recently become widespread due to more accurate modeling of biological processes.
Gas-to-Methanol Production at Lower Operating Conditions: Techno-economic Analysis of SMR, ATR, and DMR
Authors: VJ Aimikhe
Published: April 2023

Methanol production is basically through the traditional methods of Steam Methane Reforming (SMR), Auto-Thermal Reforming (ATR), and Dry Methane Reforming (DMR). However, the process is usually energy intensive, up to 100 bar and 1000oC, leading to high associated and operating costs. This study investigates the techno-economic feasibility of methanol synthesis at lower temperatures and pressures, based on the equilibrium expression presented by Turton, et al. Three (3) methanol production routes were investigated; The Steam Methane Reforming (SMR), the Auto-Thermal Reforming (ATR), and the Dry Methane Reforming (DMR). The peculiarity in each production option was simulated using Aspen HYSYS v11 software. The process parameters were rigorously optimized using the optimizer tool in Aspen HYSYS V11, in order to achieve the most economical yield while meeting the acceptable quality benchmark for the product. The initial simulations were carried out using values from the upper end of the operating ranges as stated in literatures. While monitoring the product yield and quality, the process operating parameters which essentially are the pressures and temperatures point to point through the flow schemes, were reduced to either the lower end of the operating ranges or even much lower provided, an optimum product yield rate and quality was obtained as output. The involved process equipment was sized on a preliminary level in order to estimate the plant cost using the same feed rate of 100MMscf/d of natural gas for all three cases. The simulation results showed that methanol synthesis was optimized at 40o C and 15 bar. a. Furthermore, the ATR option gave the most methanol throughput at 5128.8 MTPD, the SMR option produced 4802.4 MTPD, while the DMR had the least output at 3434.4 MTPD. All three cases proved profitable, with a payback period ranging between 4.82 to 6.52 years. Despite requiring the most capital investment of USD2.136 billion, the ATR option is the most viable technology for this production scale and the quickest to pay back invested capital (4.82 years). As such, it is the most recommended option.
Production, Characterization, and Exergy Analysis of the Soybean Biodiesel Produced by Laboratory Scale
Authors: MAS Rios
Published: April 2023

The world's hegemonic energy model is mostly based on the burning of fossil fuels. The heavy reliance on oil, coal, and natural gas for power generation as well as the pollution resulting from burning such fuels is a growing global concern. Biodiesel from the transesterification of vegetable oils is a promising alternative source for diesel engines. The ANP, National Agency of Petroleum, Natural Gas and Biofuels, regulates fuels in Brazil. In this work, soybean biodiesel was produced on a laboratory scale through an alkaline transesterification reaction. An analysis of the exegetic efficiency of the process, the physical-chemical characterization of biodiesel, and a brief discussion on the following parameters were carried out: higher and lower calorific value, water content, specific mass at 20°C, kinematic viscosity at 40°C, acidity index and oxidative stability, verifying the adequacy to the parameters of ANP Resolutions nº 45/2014 and nº 798/2019. Considering the exergetic efficiency of 63.42% and the physical-chemical characterization, despite the non-conformities in water content and oxidative stability, soybean biodiesel proved to be a satisfactory alternative for renewable fuel.

The main objective of this article is to do a comprehensive sensitivity analysis so as to study the influence of rotational speeds on the drillstring and BHA vibrations in well ZB-290 of s-shape well profile. This study is an extention of our reseach work of drillstring vibrations that were previously implemented to identify, analyze and control the resulting vibration in Zubair field wells. This well (ZB-290) has been drilled in Zubair field. Furthermore, recorded time-based vibration data and the vibration logs of this well to perform this analysis. BHAs forces, stresses, displacements, torque, and moments have been successfully identified and analysed taking into account the change of drilling speed. Drilling performance and future well designs will be enhanced based on the previous and this work.

This study aims to investigate the changes in egg production, quality, and blood, and egg cholesterol levels with age and examine the relationship between these parameters. In this context, a total of 340 eggs were used obtained from 34-53 weeks-old Brown Nick layer hens. In the experiment, egg weight and egg production were daily, egg quality and cholesterol level was weekly measured for 20 weeks. The serum cholesterol level was determined at 34, 42 and 53 weeks. According to the research results, live weight, average egg weight, weekly total egg weight and weekly egg cholesterol level increased with age. Whereas the number of weekly eggs per animal was low at the beginning, it increased towards the middle and decreased towards the end of the experiment. Among the quality parameters, yolk weight, shell weight, shell breaking strength, average shell thickness, yolk index, L and a* value of yolk color, number of blood and flesh stains were affected by increasing age, whereas albumen weight, albumen index, Haugh Unit, shape index and yolk color b* value was unaffected. And the changes in serum and egg cholesterol levels were not significant at 34, 42 and 53 weeks. On the other hand, there was a significant relationship between egg yolk weight and egg yolk cholesterol and between egg weight and egg yolk weight. The results show that egg quality traits changed with age. It is necessary to focus on new studies to improve the internal and external quality of eggs in order to extend the holding period of commercial flocks and thus increase the operating profit.

Introduction. One of surgical methods for treatment of aortic valve (AV) pathology is Aortic Valve Neocuspidalization Ozaki procedure (AVNeo). Thus, according to the latest systematic review, freedom from reoperation within one, three, five years after AVNeo was 98%, 97% and 96%. Available references provide few descriptions of reoperations after AVNeo. Aim. To analyze the immediate results of AV reinterventions after AVNeo. Materials and methods. In the medium term, reinterventions after AVNeo were necessary for 11 patients (4.3%). The age of patients ranged from 26 to 69 years. 11 patients who underwent surgery included 6 males and 5 females. Four patients had class III-IV CHF, according to NYHA classification. Three patients had previously been operated on for infective endocarditis (IE), and five patients had bicuspid aortic valve. The duration of follow-up, from AVNeo surgery to reinterventions, ranged from 3 to 43 months. Results and discussion. All patients underwent an isolated AV intervention. The main causes of dysfunction were IE (six patients) and leaflet rupture in the commissural area (five patients). Seven patients underwent aortic valve replacement with mechanical valves, one patient — with aortic homograft valve, one patient — with tissue valve and two patients underwent valve repair. In the early postoperative period, one patient had bleeding with the development of cardiac tamponade and one patient had a haemorrhagic stroke. No patients had ARF, perioperative myocardial damage, sternal infection or permanent pacemaker implantation. Two patients died during the hospital period. Conclusions. AV reinterventions are associated with a high incidence of complications and deaths. Therefore, prevention of IE and commissure enhancement should reduce the frequency of repeated interventions, which is to be confirmed by prospective studies in large cohorts of patients.

Introduction

In adults, chronic exposure to air pollution is associated with elevated blood pressure, but few studies have examined this relationship in youth. We investigated the association between annual ambient concentrations of air pollutants (fine particulate matter [PM2.5] and nitrogen dioxide [NO2]) and systolic blood pressure (SBP) among adolescents in Montréal, Canada.

Methods

Participants were students aged 15 to 17 years who provided SBP and residential postal code data in 2004/05 through their enrolment in the Nicotine Dependence in Teens study. Annual estimates for 2004 of residential exposure to NO2 and PM2.5 were provided by the Canadian Urban Environmental Health Research Consortium and linked to participants’ residential postal code. Elevated SBP was defined as SBP ≥ 90th percentile adjusted for age, sex and height. Logistic regression was used to estimate odds ratios and 95% confidence intervals (CIs) for each pollutant with respect to elevated SBP, adjusted for relevant confounders.

Results

The sample consisted of 508 adolescents (mean age: 16.9, 46% male); 4% had elevated SBP. Although estimates were not statistically significant, there were generally modest positive associations between pollutant levels and SBP. The adjusted prevalence odds ratio of elevated SBP was 1.33 (95% CI: 0.64, 3.05) for every interquartile range (IQR) increase in residential PM2.5 levels (2.1μg/m3). Similarly, the adjusted prevalence odds ratio of elevated SBP was 1.17 (95% CI: 0.47, 2.70) for every IQR increase in residential NO2 levels (10.2 ppb).

Conclusion

Findings support a possible relationship between exposure to air pollutants and increased SBP in adolescents, warranting further investigation for this important public health concern.

Nous sommes heureux que notre article sur la santé publique clinique1 ait reçu l’appui du Dr Shah2, qui mentionne également des éléments historiques importants au sujet de la santé publique clinique. Le Dr Shah a été le premier directeur d’un nouveau programme de résidence lancé en 1976 à l’Université de Toronto, soit le programme de résidence en médecine communautaire, qui porte maintenant le nom de programme de résidence en santé publique et en médecine préventive. Même s’il prétend ne pas avoir « su rassembler les cliniciens et les professionnels de la santé publique pour définir les éléments communs et les synergies nécessaires »2, nous sommes d’avis qu’il n’a pas échoué, car ses efforts ont inspiré ses étudiants (dont plusieurs ont corédigé l’article en question1). Tirant parti de son héritage important, les générations suivantes de cliniciens et de professionnels en santé publique ont fait des avancées sur le plan d’une collaboration efficace entre médecine clinique et santé publique.
