Quinic acid as a novel depressant for efficient flotation separation of scheelite from calcite
Authors: Huang Zheyu , Kuang Jingzhong , Yu Mingming , Ding Dan
Published: May 2023

There are difficulties to the conventional depressant for achieving separation of scheelite from calcite for the sake of their similar surface properties. The paper reported that a new depressant quinic acid (QA) was used for separating scheelite from calcite. The adsorption experiments, zeta potential experiment, contact angle, FTIR, XPS analysis and crystal chemistry analysis were utilized to known the depression mechanism of selectivity. The results showed that the recovery of calcite decreased drastically after QA added, whereas hardly influenced on scheelite. The tungsten concentrate could reach 66.24% WO3 grade and 89.46% recovery with 1.5×10-4 mol·L-1 QA at pH=9. The surface adsorption quantity of the QA on calcite was much greater than scheelite, which enhanced significantly the hydrophilicity of calcite surface. Due to its negative charge, QA could be adsorbed on the surface of calcite which had positive charge instead of that of scheelite with negative charge. Subsequently, free carboxyl groups of QA could chelated with Ca2+ species on the calcite surface to form stable chemical adsorption in order to prevent the Pb-BHA to form further adsorption on that, so there was no increase significantly on hydrophobicity. However, QA was obviously weak for adsorbing while Pb-BHA which could still be chemically adsorbed on scheelite surface of pre-treated with QA.

Authors: Nzeh Nnaemeka , Popoola Patricia
Published: May 2023

Primary concentrations of Azara barite deposit in Nassarawa state, Nigeria were conducted; employing simplified gravity concentration techniques. Particle size distribution, specific gravity, physicochemical and morphological analyses of the sample was conducted. These analyses were done in order to establish process efficacy and effectiveness of gravity concentration processes for recovery of barium from the ore deposit, as well as its suitability in various industrial applications, such as the oil and gas sectors. Thus, microstructural, chemical composition and certain physicochemical characteristics/properties of the mineral sample of Azara-Nassarawa barite were determined. XRD, XRF, SEM and EDS analyses were utilized in determining morphology as well as quantitative and qualitative chemical analyses of the sample. Barite sample with average particle size of -355+150µm was subjected to concentration, adopting jigging and tabling gravity separation as the concentration methods. Hitherto, based on quantitative and qualitative chemical analyses conducted, the sample was composed of about 36.2% BaO and 40.5% Ba, respectively; and also possessed an average specific gravity (SG) of about 3.85. Further, the qualitative analysis of the mineral products of jiggling and tabling indicated that jigging had a concentrate recovery of 130.98% Ba with SG increase of 11.2% while tabling had 89.81% Ba recovery with 8.6% SG increase. Assay and SG results confirm gravity concentration efficiency and thus, establish the barite from Azara-Nassarawa ore deposits suitable for certain industrial applications. This will serve as a tool and a step further towards mitigating existing problems or challenges in mineral concentration and processing of such deposits for industrial purposes.

Obesity is a prevalent health condition in older adults, with significant implications for cognitive functioning. This study aims to evaluate the relationship between obesity and cognitive functioning in a normal cognitive elderly group. We conducted a cross-sectional study to verify our hypothesis. We collected social, demographic and clinical characteristics of the participants. Cognitive evaluation included: Mini-Mental State Examination, Rey Auditory-Verbal Learning Test (RAVLT), Rey Complex Figure Test, Trail Making Test A and B and Verbal Fluency Test. There were 101 participants included and divided in 2 groups: group 1 with BMI 0-25 (34.4%) and group 2 with BMI>25 (65.6%). Participants with obesity also associated hypertension (p=0.04) and type 2 diabetes (p=0.002). Participants with obesity had worse cognitive function, especially in the attention (RAVLT Trial 1, p=0.014) and verbal fluency domains (p=0.002). Future research is needed to further explore the mechanisms underlying the association between obesity and cognitive functioning in older adults and to identify effective interventions to mitigate cognitive decline in this population.

Background and Objectives. Subjective cognitive decline (SCD) is considered a precursor for mild cognitive impairment and dementia. Depression is also a known risk factor for later cognitive decline. It is not yet known if depression is a risk factor for SCD or if SCD could be the subjective perspective of patients with depression. Methods. We conducted a cross-sectional study on patients from a primary care clinic with the following inclusion criteria age 50-80 years, with SCD, with no current depression, anxiety disorder or substance use in previous 6 months. We collected socio-demographic and clinical characteristics and applied a set of questionnaires to evaluate cognition: MMSE, Rey Auditory Verbal Learning (RAVLT), Rey-Osterrieth complex figure, verbal fluency, Trail Making Test (TMT), and HAMD- 17 and HAMA to evaluate depression and anxiety. We used Chi-Square to analyze categorical data and Student T-test for continuous variables (Mann-Whitney for non-parametric data). Results. Forty-nine patients were included in this study. Twelve patients had documented history of major depressive disorder while 37 did not (controls). Mean age in the control group was 65.8 (±7.07) and 78.4% were female while the mean age in the depression group was 63.7 (±5.47) with 83.3% females, matched by social-demographic and clinical characteristics. There is a difference regarding the presence of SCD between controls (64.9%) and depression group (91.7%) with trend regarding statistical significance (p=.074). Conclusion. A history of depression could be a risk factor for later SCD, but more studies are needed to clearly determine the full impact of depression on SCD.

Psychotherapy training is a crucial component of psychiatric education across European countries. We present an overview of the training programs offered to psychiatrists in European countries. The focus is on the different approaches, duration, and requirements for psychotherapy training across Europe. The training programs range from shorter, more focused courses to longer, in-depth programs that encompass a range of therapeutic modalities. The requirements for entry into these programs, as well as the standards of assessment, vary from country to country. In addition, there are differences in the types of therapy that are emphasized, with some countries prioritizing psychodynamic approaches and others emphasizing cognitive-behavioral therapies. This review also explores the challenges facing psychotherapy training programs in Europe, including the need to adapt to new technologies and changing healthcare systems. Overall, this review aims to provide an insight into the current state of psychotherapy training for psychiatrists in European countries.

Background and objectives. Schizophrenia is one of the top leading causes of disability worldwide, remaining despite of extensive research, one of the most common diagnoses to occupy psychiatric beds. Hospital readmission is a commonly used indicator of quality of care and it is considered incompatible with functional recovery. Taking this into consideration, clinically significant change can be translated into readmission rates. A various number of risk factors have been cited in literature, searching in different populations for a better way to complex management that can offer a highly-functional future in patients with a widely-known chronic and impairing disease. Our objective is to further study what are the possible predicting factors of the number of hospitalizations in a group of patients with schizophrenia. Methods. We conducted a study on schizophrenia patients from our clinic and demographical data was included (age, sex, environment, occupational and educational level), along with a psychiatric and somatic history, including the age of the onset, the duration of the disease, the treatment history in terms of typical or atypical antipsychotics was noted. We applied the Positive and Negative Schizophrenia Scale (PANSS) and Global Assessment of Functioning (GAF) Scale. We then analyzed the data with t-test. Results. A higher score on the Positive Scale and the General pathology Score of the PANSS test was relevant to predict a higher number of hospitalizations in this vulnerable population. Higher scores on PANSS test are a reflection of a more severe form of the pathology, representing a higher general impairment. Conclusion. There is undoubtedly an important aspect in finding more eloquent risk factors that can predict the number of hospitalizations in schizophrenia patients. The correlation between the higher score on Positive and General pathology Scale and the number of hospitalizations is an important step in coordinating further studies with the final purpose of offering better outcomes for this vulnerable population.

Consultation-liaison psychiatry is a subspecialty of psychiatry that focuses on the interface between mental health and general medical care. In Europe, consultation-liaison psychiatry has a long history and is an established field of practice. The primary goal of consultation-liaison psychiatry is to provide psychiatric assessment, diagnosis, and treatment to patients with medical or surgical conditions that impact their mental health. Consultation-liaison psychiatrists work collaboratively with medical teams to manage the psychological and emotional aspects of illness and its treatment. In addition to providing direct patient care, consultation-liaison psychiatrists also participate in research, teaching, and advocacy activities related to the interface between medicine and psychiatry.

Anti-NMDA Receptor Encephalitis is an autoimmune disorder characterized by the presence of antibodies against the NMDA receptor in the central nervous system. It usually onsets with a psychotic episode that can mimic schizophrenia, and up to 60% of patients are first admitted to a psychiatric ward. Without correct therapeutic management, it has a progressive and potentially fatal evolution. We present the case of a 38-year-old female admitted to our hospital with a psychotic episode who underwent Olanzapine treatment up to 20 mg/day without any clinical response. Therefore, the switch between Olanzapine and Aripiprazole was made, but unfortunately, her condition was not improving. After additional investigations, CSF tested positive for Ab anti-R glutamate (NMDA). Consequently, she was transferred to the neurology ward to receive proper treatment. Multiple case reports have been described in recent literature, all stating that NMDA encephalitis should be considered in the psychiatric differential diagnosis process, especially in the case of acute psychoses in young women. Thus, an interdisciplinary approach is essential for appropriately managing these cases.

Sjogren’s syndrome (SSj) is a chronic autoimmune disease mainly targeting the exocrine glands, but sometimes associating extra-glandular manifestations. Xerosis, purpura, Raynaud’s phenomenon, cutaneous vasculitis, annular erythema are the main forms of skin involvement. A 26-year-old female patient was admitted for diffuse erythematous rash and angioedema, xerophthalmia and symmetrical arthralgia of hand joints. Anti-nuclear antibodies, anti-SSA and anti-Ro52 antibodies were identified, Schirmer’s test was positive, thus the diagnoses of primary SSj and associated urticarial vasculitis were established. Treatment with oral methylprednisolone, azathioprine and hydroxychloroquine was initiated, with favorable response over the next week. Patients with primary SSj that develop cutaneous vasculitis, lymphadenopathies or lymphopenia may be at risk for additional extra-glandular manifestations, including non-Hodgkin lymphoma.

New observational facilities are probing astrophysical transients such as stellar explosions and gravitational-wave sources at ever-increasing redshifts, while also revealing new features in source property distributions. To interpret these observations, we need to compare them to predictions from stellar population models. Such models require the metallicity-dependent cosmic star formation history (

) as an input. Large uncertainties remain in the shape and evolution of this function. In this work, we propose a simple analytical function for

. Variations of this function can be easily interpreted because the parameters link to its shape in an intuitive way. We fit our analytical function to the star-forming gas of the cosmological TNG100 simulation and find that it is able to capture the main behavior well. As an example application, we investigate the effect of systematic variations in the

parameters on the predicted mass distribution of locally merging binary black holes. Our main findings are that (i) the locations of features are remarkably robust against variations in the metallicity-dependent cosmic star formation history, and (ii) the low-mass end is least affected by these variations. This is promising as it increases our chances of constraining the physics that govern the formation of these objects (https://github.com/LiekeVanSon/SFRD_fit/tree/7348a1ad0d2ed6b78c70d5100fb3cd2515493f02/).
On the 3D Curvature and Dynamics of the Musca Filament
Authors: Kaminsky Aidan , Bonne Lars , Arzoumanian Doris , Coudé Simon

Filaments are ubiquitous in the interstellar medium, yet their formation and evolution remain the topic of intense debate. In order to obtain a more comprehensive view of the 3D morphology and evolution of the Musca filament, we model the C18O(2-1) emission along the filament crest with several large-scale velocity field structures. This indicates that Musca is well described by a 3D curved cylindrical filament with longitudinal mass inflow to its center unless the filament is a transient structure with a lifetime ≲0.1 Myr. Gravitational longitudinal collapse models of filaments appear unable to explain the observed velocity field. To better understand these kinematics, we further analyze a map of the C18O(2-1) velocity field at the location of SOFIA HAWC+ dust polarization observations that trace the magnetic field in the filament. This unveils an organized magnetic field that is oriented roughly perpendicular to the filament crest. Although the velocity field is also organized, it progressively changes its orientation by more than 90° when laterally crossing the filament crest and thus appears disconnected from the magnetic field in the filament. This strong lateral change of the velocity field over the filament remains unexplained and might be associated with important longitudinal motion that can be associated to the large-scale kinematics along the filament.

Introduction. In recent decades, Madagascar has become one of the most important plant hotspots in the world. The country's remaining forests and vegetation are disappearing at an alarming rate, while dozens of new species are discovered each year. Among the plant families that have long been studied, Orchidaceae appear as one of the most charismatic, diverse and of high conservation concern. Based on a reviewed, comprehensive herbarium dataset, we have compiled a curated checklist of all orchid species occurring in Madagascar. Based on this complete dataset, we then compiled sampling effort, species diversity distribution, and some general statistics on their ecology and IUCN conservation status.

Methods. We compiled and standardised a global dataset using five public databases as the main data sources, supplemented by the most recent publications. The database contains ~10 000 geolocated records collected between 1816 and 2021. We used GIS software and rarefaction methods to examine sampling and diversity patterns.

Results. According to your dataset, there are currently 917 orchid species collected in Madagascar, of which 766 orchid species (83.5%) are endemic. Doubling the sampling effort could lead to the discovery of around 100 more species, bringing the total estimated number of orchid species in Madagascar to between 986 and 1056. About one-third (297 species) of all orchid species are known only by type specimens (190 species) or have not been collected in Madagascar for more than 50 years (213 species). Although the raw data show that the Andasibe-Moramanga area would have the highest orchid species concentration, our analysis of the data adjusted for bias shows that the centres of orchid diversity in Madagascar are in the Tsaratanàna Strict Nature Reserve and the Ranomafana National Park. Life form statistics show that 55.0% of orchid species are strict epiphytes. The main flowering period of orchids in Madagascar is between November and March. To date, 84% of the 226 Malagasy orchid species listed in the IUCN Red List are threatened with extinction (CR, EN or VU).

Conclusion. Despite geographically uneven coverage, the biodiversity of Malagasy orchids appears to be already well documented. We provide maps corrected for sampling bias that indicate priority areas for future surveys. Upcoming efforts should also focus on rediscovery and conservation of rare and/or threatened species, and ensure that the protected area network is well aligned with the distribution of priority species for conservation. Finally, the conservation status of 75% of the orchid species found in Madagascar is not yet known, and the inclusion of these species must be a top priority in the coming years.
Rediscovering a species not seen for a hundred years, Stathmopoda tacita (Meyrick, 1913) (Lepidoptera, Stathmopodidae), with its unusual fern-spore-feeding life history
Authors: Shen Zong-Yu , Hsu Yu-Feng

Despite being the second largest group of vascular plants, ferns are scarcely reported being fed by insects when compared to angiosperms. Within these fern-feeding insects, lepidopterans are poorly represented and are restricted only to specific groups in this speciose order. The consumers specialising on fern spores are even scarcer in the order, with the majority being consumers of vegetative structures. Amongst the fern-spore-feeding Lepidoptera, Stathmopodidae is the family with the highest species diversity, even with a subfamily, Cyprininae Sinev, 2015, specialising on fern spores. However, fern-spore-feeding habit is not restricted to this subfamily. To understand the evolution of fern-spore-feeding within this family and to increase our knowledge of insect-fern evolution, detailed studies on fern-spore feeding stathmopodids are essential.

The present study rediscovered a rare, fern-spore-feeding, stathmopodid micro-moth, Stathmopoda tacita (Meyrick, 1913), which has not been formally recorded or identified for more than 100 years. We documented the life history of this species and identified several species of Pyrrosia (Polypodiaceae, Platycerioideae) as host for the moth’s larvae. A re-description of the fern-feeding moth is also provided as the original description is obscure in terms of character diagnosis.
Evidence using morphology, molecules, and biogeography clarifies the taxonomic status of mole crabs of the genus Emerita Scopoli, 1777 (Anomura, Hippidae) and reveals a new species from the western Atlantic

Uncertainties regarding the taxonomic status and biogeographical distribution of some species of the genus Emerita from the western Atlantic led to thorough examination of the subtle morphological differences between two coexistent species (E. brasiliensis Schmitt, 1935 and E. portoricensis Schmitt, 1935) along the Brazilian coast and compare them using two genetic markers. The molecular phylogenetic analysis based on sequences of the 16S rRNA and COI genes showed that individuals identified as E. portoricensis were clustered into two clades: one containing representatives from the Brazilian coast and another containing specimens distributed in Central America. Our molecular-based phylogeny, combined with a detailed morphological analysis, revealed the Brazilian population as a new species, which is described here as Emerita almeidai Mantelatto & Balbino, sp. nov. The number of species in the genus Emerita is now raised to 12, with five of them occurring in the western Atlantic, five in the Indo-Pacific, and two in the eastern Pacific.
Les « Chroniqueurs du malheur » : des Lorrains parlent de leur guerre de Trente Ans
Authors: Martin Philippe
Published: May 2023

Temps d’une crise exceptionnelle, la guerre de Trente Ans a donné naissance à d’innombrables récits personnels pour tenter d’expliquer le malheur, de dépasser la souffrance, de redonner de l’ordre dans un monde éclaté… Région particulièrement touchée, la Lorraine fournit une impressionnante collection d’écrits du malheur. Ils sont de trois types. D’abord les écritures de l’urgence, répondant au besoin de faire face à la violence immédiate. Ensuite, les chroniques et journaux qui expliquent et réorganisent. Enfin, ceux qui développent une écriture plus soignée, vers ou romans.
L’imprimé pendant la guerre de Trente Ans, entre information et divertissement. Le fossoyeur de Leipzig, 1632
Authors: Félicité Indravati
Published: May 2023

En septembre 1631, la bataille de Breitenfeld, à quelques kilomètres au nord de Leipzig, voyait la victoire d’une puissante alliance entre princes protestants. Sous l’égide de Gustave Adolphe, le camp évangélique était rassuré. Quelques mois après le traumatisant sac de Magdebourg, les évangéliques pouvaient désormais se prévaloir du soutien de l’Électeur de Saxe et d’une opinion publique choquée par la cruauté des troupes impériales. À l’époque, la ville de Leipzig, bien qu’assiégée elle aussi, n’eut pas à subir les assauts militaires alors que le général Tilly, chef redouté des armées de la Ligue catholique nommé depuis peu à la tête des troupes impériales, était déjà aux portes de la ville. Les contemporains s’interrogeaient sur les raisons de cette mansuétude. Certains y voyait le résultat des négociations du conseil municipal avec l’envoyé de Tilly, Egon VIII de Fürstenberg. Pour d’autres, en revanche, Tilly avait changé d’avis au cours d’un bref séjour dans la maison du fossoyeur de Leipzig, sans que l’on connaisse les raisons de ce revirement. Ainsi naquit la légende du fossoyeur de Leipzig. Dans la maison de ce dernier, Tilly aurait appris sa mort prochaine, ce qui l’aurait dissuadé de réitérer le massacre perpétré quelques mois plus tôt dans la ville de Magdebourg. À partir d’un imprimé revenant sur cette rencontre, le présent article propose une analyse des évolutions culturelles qui accompagnent les événements militaires.
