The ‘Habitats’ Directive (HD 92/43/EEC) is one of the primary legal tools aiming at conserving nature in Europe. Due to the complex iter to revise it, the habitats listed in the Annex I have been seldom updated after the HD adoption. Basing on already available information and expert knowledge, this paper presents a preliminary list of relevant habitats occurring in Sardinia, not yet considered and worth to be placed in the Annex I. Two new habitat proposals, one habitat new for Italy, and nine new subtypes of already existing HD habitats are here described. Most of the proposed new habitats and subtypes have a limited distribution range, due to the high number of narrow, often endangered, endemic species that characterize them. Being neglected, they are consequently poorly investigated, inconstantly monitored and unprotected. Thus, the main aim of this paper is to promote their conservation through implementation of HD and its interpretation manuals.

The data on the dynamics of e-waste generation in different countries are presented and modern methods of handling this type of waste are analyzed. The characteristics of the component composition of electronic waste are given. The problem of neutralization and disposal of mobile phone screens has been studied. An analysis of possible methods for extracting metals from electronic waste has been carried out, which has shown the promise of a biotechnological method based on the ability of the biomass of microscopic algae to selectively, under certain conditions, sorbs metals. Based on the analysis of the research results of domestic and foreign scientists presented in the literature the process of extracting indium from the screens of mobile phones using microscopic algae was simulated under laboratory conditions. When justifying the choice of indium as an extractable metal, two criteria were used: limited distribution in the earth's crust and the difficulty of obtaining from natural ores, as well as demand in various industries. In experimental studies, the parameters of the effective extraction of indium by the biosorption method have been determined.

The bean (Phaseolus vulgaris) pathogen Pseudomonas syringae pv. phaseolicola NPS3121 synthesizes phaseolotoxin in a thermoregulated way, with optimum production at 18 °C. Gene PSPPH_4550 was previously shown to be thermoregulated and required for phaseolotoxin biosynthesis. Here, we established that PSPPH_4550 is part of a cluster of 16 genes, the Pbo cluster, included in a genomic island with a limited distribution in P. syringae and unrelated to the possession of the phaseolotoxin biosynthesis cluster. We identified typical non-ribosomal peptide synthetase, and polyketide synthetase domains in several of the pbo deduced products. RT-PCR and the analysis of polar mutants showed that the Pbo cluster is organized in four transcriptional units, including one monocistronic and three polycistronic. Operons pboA and pboO are both essential for phaseolotoxin biosynthesis, while pboK and pboJ only influence the amount of toxin produced. The three polycistronic units were transcribed at high levels at 18 °C but not at 28 °C, whereas gene pboJ was constitutively expressed. Together, our data suggest that the Pbo cluster synthesizes secondary metabolite(s), which could participate in the regulation of phaseolotoxin biosynthesis.

Abstract The present article demonstrates how the so far unchallenged misanalysis within Chinese linguistics of a few, but central, data points has led to a distorted picture biasing, inter alia, the general typology of wh-in-situ languages as well as the crosslinguistic study of Quantifier Phrases. This is the case for méi yǒu rén ‘not exist person’, hěnshǎo yǒu rén ‘rarely exist person’, and zhǐ yǒu DP ‘only exist DP’, which are not nominal projections equivalent of ‘nobody’, ‘only DP’, and ‘few people’ as currently assumed, but existential constructions: ‘there isn't anybody’, ‘there is only DP’, and ‘there are rarely people’. In addition, a subset of speakers has reanalyzed hěnshǎo (yǒu) rén with a covert yǒu ‘exist’ as a QP hěnshǎo rén ‘few people’. A corpus study highlights the limited distribution of hěnshǎo rén ‘few people’, which shows that it is not on a par with its antonym hěn duō rén ‘many people’.

Framboids are microscopic subspherical clusters of equant and equidimensional microcrystals. They overwhelmingly consist of the mineral pyrite, cubic FeS2. There are about 1030 framboids on Earth and they are forming at a rate of about 1014 per second. They may be the most abundant mineral texture on Earth. Framboids are especially concentrated in sediments, although they are also to be found in the water column and in high temperature systems. The oldest framboids are possibly 2.9 Ga and they are found in all geologic periods from that time. The first framboids were described in 1885 from a peat bog, and the term framboid was coined in 1935. They have fascinated researchers ever since, not least because a substantial fraction of them display astonishing regular microarchitectures where their constituent microcrystals are geometrically ordered. Understanding of the nature of framboids has paralleled technological advances in microscopy, structural and chemical analyses, and computing. The sulfur in sedimentary framboids is almost exclusively sourced from sulfate-reducing bacteria, and the idea that framboids were fossil microorganisms was first propounded in 1923. Subsequently, the limited distribution of organic matter in framboids, its absence in hydrothermal framboids, and inorganic framboid syntheses showed that organisms were not necessary for framboid formation.

Abstract Purpose Results of the first ASHP National Survey of Health-System Specialty Pharmacy Practice are presented. Methods A sample of 230 leaders in health-system specialty pharmacies were contacted by email and invited to participate in a survey hosted using an online survey application. The survey sample was compiled from ASHP member lists, through review of data from other ASHP surveys indicating the presence of specialty pharmacies, and by outreach to ASHP member organizational leaders. Results The response rate was 53.0%. Most health-system specialty pharmacies dispense 30,000 or fewer specialty prescriptions per year, have an annual revenue of $100 million or less, are part of an entity eligible to participate in the 340B Drug Pricing Program, operate 1 specialty pharmacy location, have at least 1 specialty pharmacy accreditation, dispense nonspecialty medications in addition to specialty medications, and employ an average of 13 pharmacists and 15 technicians. More than two-thirds of health-system specialty pharmacies (68.8%) dispense no more than half of the prescriptions written by their providers due to payer network restrictions or limited distribution drugs. The health-system specialty pharmacy practice model includes access to the electronic health record (100% of respondents), pharmacists and technicians dedicated to specific clinics (64.9% and 57.7%, respectively), specialty pharmacist involvement in treatment decisions and drug therapy selection prior to the prescription being written (64.9%), and documenting recommendations and progress notes in patients’ electronic health record (93.4%). Most health-system specialty pharmacies (83.3%) offer experiential or formal education in specialty pharmacy. Top challenges that survey respondents expected to face in the next year included restricted access to payer networks and limited distribution drugs, 340B Drug Pricing Program changes, and shrinking reimbursement from payers. Conclusion The health-system specialty pharmacy represents an integrated advanced practice model that incorporates specialty medication-use management across the continuum of care.

The tree monitors, Varanus (Hapturosaurus) are highly valued in international pet trade. These lizards are somewhat striking in their colouration, among which is the Blue tree monitor, Varanus macraei. Body colouration of this species is dominantly blue, which is unique to this monitor lizard species. This distinctive colouration together with its limited distribution has put the species as high-priced export commodity for at least 20 years. Because the lizard is endemic to Batanta Island and the nearby islets in the Raja Ampat Islands, Indonesia, we made a trip to the islands in 2019. We visited the village of Amdui on Batanta, where we made several casual interviews with hunters. Here we report results of our interviews and brief survey on the habitats of V. macraei, in order to identify the roles of local hunters in the trade of tree monitors for international pet markets. Some residents of Amdui have been in search for Blue tree monitors and other monitor lizard species since mid1990s and continue their hunt until very recently for fast cash. Because hunting is yet a large part of their culture more than farming, villagers rely on this method for subsistence. We recommend a socio-cultural approach to inform hunters on the idea of sustainability of harvest, for which a stable livelihood will be a possible consequence.

The aim of Stridon – Journal of Studies in Translation and Interpreting is to advance research in translation- and interpreting-related phenomena, and to publish articles on the theoretical, descriptive and applied research within the field of Translation and Interpreting Studies. Besides established authors, we will also welcome articles by new voices in the field, focusing not only on translation and interpreting, but also on interdisciplinary translation- and interpreting-related sociological, literary, cultural, historical, educational and contrastive topics. Stridon’s particular aim is to present the research involving peripheral languages and languages of limited distribution, and the research focusing or originating from central or southeastern Europe. Since, traditionally, Translation and Interpreting Studies research has prioritised the focal over the marginal, this journal would like to give voice to the perspective of the Other in Translation Studies.

The morphological and ultrastructural descriptions of the larvae of two cave species of Trechini—Duvalius (Hungarotrechus) subterraneus (L. Miller, 1868) and Duvalius (Biharotrechus) paroecus (J. Frivaldszkyi, 1865)—are presented in this paper. The interest in studying these larvae lays in their rarity and the limited distribution of the Duvalius species. The larvae were collected from caves in the Romanian Carpathians and were examined under a stereomicroscope and scanning electron microscopy. New important taxonomical and fine morphological characteristics are discussed together with conclusions on the larvae microhabitat as part of the measures to be taken by a proper management of caves.
