Authors: Tiwari Ruchi , Lahiri Akanksha , Tiwari Gaurav , Vadivelan Ramachandran
Published: December 2021

The present study assessed the topical potential of nanofibers loaded with Mupirocin (MUP) for the treatment of burns. Nanofibers of MUP were composed of Polyvinyl Pyrrolidone (PVP), Gelatin Type-A, and Ethanol using two methods: Solvent casting and Electrospinning. Nanofibers were characterized for Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Differential scanning calorimetry (DSC), Thermogravimetric analysis (TGA), Drug Content Studies, in-vitro drug permeation, antibacterial and stability studies. The FT-IR studies showed that the Electrospinning technique had a very good mixing of MUP with the polymer. SEM studies showed that the morphology of electrospinning nanofibers had diameters in the range of 70.41 nm- 406.83 nm. The thermal decomposition studies of optimized Nanofiber (E.S.1) were performed by DSC and TGA study and it was found that the formulation had high stability in high-temperature environments. Permeation studies showed that E.S.1 had the highest percentage amount and controlled release of the drug (90 %) up to 8 has compared to other formulations. Nanofibers prepared through the Electrospinning technique showed better antibacterial activity against Staphylococcus aureus as compared to the Solvent casting nanofibers. This research suggested that MUP loaded nanofibers can be potentially used as a topical drug delivery system for the treatment of burns.

Published: December 2021

Caregivers are a particular target for psychosocial risks, including stress and burnout. Burnout is aconsequence of exposure to permanent and prolonged stress. It concerns professions with high mental,emotional and emotional demands and high responsibility such as nurses. The objective of this studywas to describe and identify psychosocial risks, occupational stress and its components in healthprofessionals. This epidemiological study involved 191 health professionals working in the provincialhospital centers of Kenitra and Sidi Slimane, Morocco. The questionnaire included: socio-demographicand occupational data; the Karasek scale (KJCQ) with its three components: psychological demand (DP),decision-making latitude (LD) and social support (SS). These three dimensions allow the identificationof risk situations. Job strain is the combination of low decision latitude and high psychological demand.The Maslach Burnout Inventory (MBI) scale consists of three dimensions (emotional exhaustion,depersonalization and feeling of personal fulfillment at work). The positive diagnosis of burnout waschosen if the score exceeded the values defined in one of the three components of MBI (high for thefirst two and low for the third).

The first quarter of 2020 is one of the most difficult times for the region and whole world. Wherethe epidemic (COVID-19) invaded the world and thus affected many aspects of human aspects: interms of low industrial production, the global economy stopping work, and educational aspects closedto students. All educational institutions modified their academic assessments, and then educationalprograms were modified during this period. As stakeholders and management of higher educationinstitutions do not have another option is to take advantage of Internet and new technologies, andtherefore go to online learning to continue academic activities at all levels of education around theregion and the whole world.The study aims at assess whether students in KSA, especially Alasala University in general, and inparticular the College of Law, if they are satisfied with the “group” online learning experience in highereducation institutions, therefore, the study used an online survey to investigate the level of satisfactionwith online learning and how students adapt to these “new initiatives”.The study undertakes a case study of a law school within a leading university such as Alasala, which hasimplemented a quality system. The study reviews the development of the quality system and examinesthe concept of service quality in law education. The aim of this study is to address the paucity of servicequality research in law education in this region. Empirical research is used to determine the factorsthat influence student evaluation of service quality. With data collected from 664 students, the studyidentifies six factors that influence students’ evaluations of service quality. Research implications of thestudy are then discussed. The study results indicate that the implementation of online learning programswas a very impressive idea as the majority of students included in the sample supported the initiative.

Autophagic flux impairment is recently reported as a cardinal factor in acute pancreatitis (AP)pathogenesis. Niclosamide, an anthelmintic drug, has been lately proved to be a potent autophagyenhancer. The diminution of the various inflammatory factors unrestrained release via autophagyimprovement may be helpful to improve the prognosis of AP. This study spots on investigating thepotential ameliorative effect of niclosamide on autophagic flux and its consequent curative outcomeon L-arginine-induced AP in rats. Thirty male wistar rats were divided into three groups. The first oneis the control one, the second is L-arginine induced AP group, the third group is niclosamide treatedL-arginine induced AP. Serum lipase, amylase, pancreatic tissue homogenate IL6, IL1β, TNFα, NF-kB,oxidative stress biomarkers; glutathione peroxidase activity, Hydroxy-2’-Deoxy-Guanosine and totalantioxidant capacity levels were evaluated. Besides, the DNA-binding activity of nuclear erythroidrelated factor 2 (Nrf-2) was assessed using a pancreatic tissue nuclear extract. Both LC3-II subunit &P62 mRNA were quantified using PCR technique. Morphometric analysis of histopathological changeswas done. The obtained data showed that niclosamide improved L-arginine induced AP as evidencedby significantly reduced serum lipase and amylase levels, which could be related to improvement ofautophagy flux impairment as evidenced by decreased levels of LC3-II and p62 expression in pancreaticcells, in addition to anti-inflammatory effect as evidenced by decreased NF-kB and proinflammatorycytokines levels, along with improving the antioxidant capacity of the pancreatic tissue. As manifestedby elevation of Nrf-2- DNA binding activity and normalization of oxidative stress biomarkers levels.These results could pave the way for niclosamide as a potential therapeutic role in acute pancreatitis.

Published: December 2021

We employed tight-binding calculations and Green’s function formalism to investigate the effect of applied electric fields on the energy band and electronic properties of bilayer armchair graphene nanoribbons (BL-AGNRs). The results show that the perpendicular electric field has a strong impact on modifying and controlling the bandgap of BL-AGNRs. At the critical values of this electric field, distortions of energy dispersion in subbands and the formation of new electronic excitation channels occur strongly. These originate from low-lying energies near the Fermi level and move away from the zero-point with the increment of the electric field. Phase transitions and structural changes clearly happen in these materials. The influence of the parallel electric field is less important in changing the gap size, resulting in the absence of the critical voltage over a very wide range [–1.5 V; 1.5 V] for the semiconductor-insulator group. Nevertheless, it is interesting to note the powerful role of the parallel electric field in modifying the energy band and electronic distribution at each energy level. These results contribute to an overall picture of the physics model and electronic structure of BL-AGNRs under stimuli, which can be a pathway to real applications in the future, particularly for electronic devices.
Büyük Menderes Nehri Havzasının Doğusunda MÖ II. Bin Yıla Ait Hilal Biçimli Tezgah Ağırlıkları (Bir Grup Piramidal Ağırlıkla Beraber)*

Published: December 2021

Afyonkarahisar’ın güneybatısında Menderes Nehri’nin ilk kaynaklarının çıktığı Dinar çevresinden Acıgöl kesimine doğru uzanan alanda tarafımızdan tekstil üretimine işaret eden çok sayıda buluntu tespit edilmiştir. Bunlar arasında büyük kısmı hilal biçimli, bir kısmı da piramidal şekilli olan ve çoğunlukla MÖ II. bin yıla tarihlenen tezgah ağırlıkları bölgedeki üretim ve ekonomik gelişmelerle ilgili referans teşkil etmektedir. Bu havzayı çevreleyen Yakaköy Kocahöyük, Dazkırı Ağılların Önü, Evciler Kocahöyük ve Dinar Dikici Höyük gibi yerleşmelerin MÖ II. bin yıla tarihlenen tekstil ağırlıkları ile seramik buluntularının yoğunluğu, konumları ve başta Yakaköy Kocahöyük olmak üzere bu dört büyük iskanın 10-16 hektar aralığında geniş alanlara yayılmasından yola çıkarak bunların ekonomik veya belki de siyasi yönden dönemlerinin ana merkezleri olabilecekleri düşünülebilir. Bu yerleşmeler arasında hilal biçimli ağırlıklarının en yoğun olarak görüldüğü Yakaköy Kocahöyük aynı zamanda 16 hektarın üzerine çıkan genişliği ve 14 m’lik mevcut yüksekliğiyle ön plana çıkmaktadır. Burada diğerlerine göre çok daha fazla tezgah ağırlığı tespit edilmiştir ancak havzayı çevreleyen diğer yerleşmelerde de hilal ya da piramidal ağırlıklara rastlanması bu kesimde tekstil üretiminin genel anlamda yaygın bir şekilde yapıldığına işaret eder. Bu çevrede tespit ettiğimiz ağırlıklar aynı zamanda MÖ II. bin yılın ilk çeyreğine ait yazılı belgelerde sözü edilen tekstil üretimi ve bölgeler arası ticaret kapsamında değerlendirilebilir. Dikici Höyük üzerinden Ağılların Önü yerleşmesine doğru uzanan tarihi doğal yol güzergahı söz konusu ticari faaliyetler için uygun bir zemin oluşturmuş olmalıdır. Bunun yanında mevcut hilal biçimli ağırlıkların birbirine yakın form özellikleri vermesi üretimdeki organizasyon veya merkezi bir üretim anlayışının da işaretleri sayılabilir.
Hulefâ ve Ulemâ Arasında Bir Rekabet ya da İş Birliği Alanı Olarak Savaş İdaresi (2-3/8-9. Yüzyıllar)

Published: December 2021

İslam tarihinin ilk yüzyılları üzerine yapılan bazı çalışmalarda, savaşın (cihâd) ilan ve idare yetkisi üzerine halife ve din âlimleri arasında rekabet yaşandığı, zühtçülükleri nedeniyle sınırlara cihat yapmak üzere giden din âlimleri ve onların emrindeki gönüllü din savaşçılarının devletle hiçbir münasebetlerinin olmadığı ve bu gerilimin savaş liderliği ve hatta dini otoritenin halifeden hadis ilmiyle de ilgilenen bu zâhit-savaşçılara geçmesiyle sonuçlandığı iddia edilmektedir. Bu çalışmada, tarihsel verilerin böyle bir varsayımda bulunmak için yeterli olmadığı savunulmakta, iki taraf arasında savaşın ilan ve idaresi konusunda bir anlaşmazlık yaşanmadığı, aksine din âlimlerinin cihat doktrininde siyasi konjonktürü, yani aslında devletin ihtiyaçlarını dikkate alarak belirli revizyonlar yaptıkları ileri sürülmektedir.
Geray Hanedanının Osmanlı Devleti Topraklarında Kalan Maddi İzleri
Authors: Kırımlı Hakan
Published: December 2021

Üç buçuk asır boyunca Kırım Hanlığı’na hükümdar veren Geray hanedanı mensupları XVI. yüzyıldan itibaren Osmanlı Devleti topraklarında yerleşmeye başlamışlardır. O kadar ki, XVIII. yüzyılda bu geniş hanedanın Osmanlı topraklarında yaşayan mensuplarının sayısı Kırım’da kalanların çok üzerine çıkmıştır. 1783’te Kırım Hanlığı’nın Rusya tarafından ortadan kaldırılmasını müteakip, Kuzey Kafkasya’ya yerleşenler dışında Geray hanedanı mensuplarının büyük çoğunluğu Osmanlı Rumelisi’nde toplanmıştır.

Osmanlı topraklarında yaşayan Geraylar burada geçirdikleri yüzyıllar içinde orada doğmuş, ölmüş ve sayısız mimarî eserler inşa ettirmişlerdir. Bu makalemiz bu coğrafyada Geraylardan kalabilen eserlerin bir dökümünü vermeyi amaçlamaktadır. Eski Osmanlı topraklarında Geraylardan geride kalan maddi izlerin büyük çoğunluğu mezar taşları olup, diğerleri iki türbe, bir köprü, bir çeşme, iki konak ile hamam, saray ve savunma kulesi kalıntılarından oluşmaktadır. Bunlar bugünkü Türkiye, Bulgaristan ve Yunanistan arazilerine dağılmış durumdadır. Muhakkak ki, günümüze ulaşabilen bu eserler bir zamanlar mevcut olanların çok küçük bir kısmından ibarettir. Söz konusu maddi izlerin tamamına yakını gayet harap ve restorasyona muhtaç durumdadır. Bununla birlikte, bu hanedan mensuplarının kendi vatanları olan Kırım’daki maddi izlerinin maruz bulunduğu muazzam tahribat göz önüne alındığında eski Osmanlı topraklarında kalabilen bu nispeten az sayıdaki izlerinin ve onların muhafazasının tarihî açıdan çok büyük önemi haiz olduğu ortaya çıkmaktadır.

Introduction. SARS-CoV-2 virus infection affects all age groups. In children, the infection mainly causes asymptomatic or mildly symptomatic forms of the disease, regardless of their immune status. Case presentation. We describe the case of a 7-year-old male child, known to have Fanconi anemia, scheduled for bone marrow transplantation. The patient comes from a family outbreak of COVID-19, which is why he was tested for SARS-CoV-2 infection. He is asymptomatic at the time of admission to our clinic. The clinical examination performed at the time of admission shows a patient in good general condition, afebrile, with pale skin and mucous membranes, without respiratory changes. Paraclinically, severe neutropenia, severe normochromic normocytic anemia and severe thrombocytopenia are detected, for which transfusions of erythrocyte mass and platelet mass are performed. Due to the immunocompromised status, antibiotic therapy is instituted. If necessary, symptomatic treatment is administered. The evolution is favorable, and the SARS-CoV-2 RT-PCR control test is negative on the eighth day of hospitalization. Conclusions. Immunocompromised status is not a major risk factor for severe COVID-19 in children.

During HIV infection, hematological manifestations are frequently associated with various pathogenic mechanisms, which require a multidisciplinary approach. We present the case of a 57-year-old patient with pancytopenia associated with Kaposi's sarcoma, as indicative manifestations of the acquired immunodeficiency syndrome. The late diagnosis of HIV infection, in the stage of severe immunosuppression, the association of opportunistic neoplasia, delayed oncological therapy and the development of immune reconstruction syndrome after starting antiretroviral therapy have contributed to the severe evolution and death of the patient.

Prevention of venous thromboembolic complications (pulmonary embolism, stroke, deep vein thrombosis) remains the most important clinical medicine problem and affects all doctors’ professional expertise areas without exeption due to an extremely high potential risk to the health and life of patients that might cause thromboembolic complications. A worldwide trend is to use conservative methods of treatment and prevention of pulmonary embolism, stroke, deep vein thrombosis, which are most often limited to the use of compression treatment, periodic appointment of phlebotropic medications courses.
At the same time, effective and safe methods of using non-drug technologies for the prevention of thromboembolic complications in patients, in particular, with postphlebitic lower extremities syndrome, are in progress. They can prevent and/or significantly reduce the number of life-threatening complications and mortality with minimal risk of bleeding.
The article presents a review of the literature data using the Russian and foreign sources on the use of medicinal and non-medicinal,mechanical methods of medical rehabilitation and sanatorium-resort treatment of patients with preventive effect on the dangerous thromboembolic complications occurrence.
Actors, Ruptures, and Continuity : New Socialist Order or Legacy of the War Economy: The Hungarian Vehicle Industry around 1950
Authors: Bódy Zsombor
Published: December 2021

This article investigates the formation of a Hungarian socialist enterprise in the vehicle industry. After giving an overview of the legacy of World War II in a (nationalized) vehicle industry plant, it explores political, production, and wage conflicts on the basis of company and party archives and considers the kinds of resources which workers and engineers could use in their efforts to assert their interests. It also considers how these efforts limited the abilities of the central economic authorities to exert influence. It arrives at the conclusion that the main features of the early socialist enterprises, such as technology, the structure of the skilled workforce, the attitudes of this workforce, etc., were shaped by the industrial boost which had come with the war. Furthermore, the relationship between workers and firms was itself shaped by the shortage of consumer goods during and after the war, because the supply of consumer goods (above all, food) was considered the responsibility of the enterprises. These circumstances set narrow limits within which the central economic administration had to operate in is efforts to create so-called socialist enterprises. So, the early socialist enterprise seems to have had few genuinely socialist elements. It was shaped far more by the prevailing conditions in the postwar context, networks among engineers, and a sense of solidarity among skilled workers which had been inherited from the pre-socialist era.
A New Absolute Proper Motion Determination of Leo I Using HST/WFPC2 Images and Gaia EDR3

Published: December 2021

We measure the absolute proper motion of Leo I using a WFPC2/HST data set that spans up to 10 yr to date the longest time baseline utilized for this satellite. The measurement relies on ∼2300 Leo I stars located near the center of light of the galaxy; the correction to absolute proper motion is based on 174 Gaia EDR3 stars and 10 galaxies. Having generated highly precise, relative proper motions for all Gaia EDR3 stars in our WFPC2 field of study, our correction to the absolute EDR3 system does not rely on these Gaia stars being Leo I members. This new determination also benefits from a recently improved astrometric calibration of WFPC2. The resulting proper-motion value, (μ

Tracing the Milky Way’s Vestigial Nuclear Jet
Authors: Cecil Gerald , Wagner Alexander Y. , Bland-Hawthorn Joss , Bicknell Geoffrey V. , Mukherjee Dipanjan
Published: December 2021

MeerKAT radio continuum and XMM-Newton X-ray images have recently revealed a spectacular bipolar channel at the Galactic Center that spans several degrees (∼0.5 kpc). An intermittent jet likely formed this channel and is consistent with earlier evidence of a sustained, Seyfert-level outburst fueled by black hole accretion onto Sgr A* several Myr ago. Therefore, to trace a now weak jet that perhaps penetrated, deflected, and percolated along multiple paths through the interstellar medium, relevant interactions are identified and quantified in archival X-ray images, Hubble Space Telescope Paschen α images and Atacama Large Millimeter/submillimeter Array millimeter-wave spectra, and new SOAR telescope IR spectra. Hydrodynamical simulations are used to show how a nuclear jet can explain these structures and inflate the ROSAT/eROSITA X-ray and Fermi γ-ray bubbles that extend ± 75° from the Galactic plane. Thus, our Galactic outflow has features in common with energetic, jet-driven structures in the prototypical Seyfert galaxy NGC 1068.
RELICS: ICL Analysis of the z = 0.566 Merging Cluster WHL J013719.8–08284

Published: December 2021

We present a pilot study of the intracluster light (ICL) in massive clusters using imaging of the z = 0.566 cluster of galaxies WHL J013719.8–08284 observed by the RELICS project with the Hubble Space Telescope. We measure the ICL fraction in four optical ACS/WFC filters (F435W, F475W, F606W, and F814W) and five infrared WFC3/IR bands (F105W, F110W, F125W, F140W, and F160W). The ICL maps are calculated using the free-of-a-priori-assumptions algorithm CICLE, and the cluster membership is estimated from photometric properties. We find optical ICL fractions that range between ∼6% and 19%, in nice agreement with the values found in previous works for merging clusters. We also observe an ICL fraction excess between 3800 Å and 4800 Å, previously identified as a signature of merging clusters at 0.18 < z < 0.55. This excess suggests the presence of an enhanced population of young/low-metallicity stars in the ICL. All indicators thus point to WHL J013719.8–08284 as a disturbed cluster with a significant amount of recently injected stars, bluer than the average stars hosted by the cluster members and likely stripped out from infalling galaxies during the current merging event. Infrared ICL fractions are ∼50% higher than optical ones, which could be signatures of an older and/or higher-metallicity ICL population that can be associated with the buildup of the brightest cluster galaxy, passive evolution of previously injected young stars, or preprocessing in infalling groups. Finally, investigating the photometry of the cluster members, we tentatively conclude that WHL J013719.8–08284 fulfills the expected conditions for a fossil system progenitor.

e
= 560 pc, median ellipticity of ϵ = 0.30, and median Sérsic index of n = 0.72. We separate the satellites into late- and early-type (29.6% and 70.4%, respectively). The mass–size relations are very similar between them within ∼5%, which indicates that the quenching and transformation of a late-type dwarf into an early-type one involves only very mild size evolution. Considering the distribution of apparent ellipticities, we infer the intrinsic shapes of the early- and late-type samples. Combining with literature samples, we find that both types of dwarfs are described roughly as oblate spheroids that get more spherical at fainter luminosities, but early-types are always rounder at fixed luminosity. Finally, we compare the LV satellites with dwarf samples from the cores of the Virgo and Fornax clusters. We find that the cluster satellites show similar scaling relations to the LV early-type dwarfs but are roughly 10% larger at fixed mass, which we interpret as being due to tidal heating in the cluster environments. The dwarf structure results presented here are a useful reference for simulations of dwarf galaxy formation and the transformation of dwarf irregulars into spheroidals.

Using the CoDa II simulation, we study the Lyα transmissivity of the intergalactic medium (IGM) during reionization. At z > 6, a typical galaxy without an active galactic nucleus fails to form a proximity zone around itself due to the overdensity of the surrounding IGM. The gravitational infall motion in the IGM makes the resonance absorption extend to the red side of Lyα, suppressing the transmission up to roughly the circular velocity of the galaxy. In some sight lines, an optically thin blob generated by a supernova in a neighboring galaxy results in a peak feature, which can be mistaken for a blue peak. Redward of the resonance absorption, the damping-wing opacity correlates with the global IGM neutral fraction and the UV magnitude of the source galaxy. Brighter galaxies tend to suffer lower opacity because they tend to reside in larger H ii regions, and the surrounding IGM transmits redder photons, which are less susceptible to attenuation, owing to stronger infall velocity. The H ii regions are highly nonspherical, causing both sight-line-to-sight-line and galaxy-to-galaxy variation in opacity. Also, self-shielded systems within H ii regions strongly attenuate the emission for certain sight lines. All these factors add to the transmissivity variation, requiring a large sample size to constrain the average transmission. The variation is largest for fainter galaxies at higher redshift. The 68% range of the transmissivity is similar to or greater than the median for galaxies with M
UV ≥ −21 at z ≥ 7, implying that more than a hundred galaxies would be needed to measure the transmission to 10% accuracy.

Calvera (1RXS J141256.0+792204) is an isolated neutron star detected only through its thermal X-ray emission. Its location at high Galactic latitude (b = +37°) is unusual if Calvera is a relatively young pulsar, as suggested by its spin period (59 ms) and period derivative (3.2 × 10−15 s s−1). Using the Neutron Star Interior Composition Explorer, we obtained a phase-connected timing solution spanning four years, which allowed us to measure the second derivative of the frequency

Hz s−2 and to reveal timing noise consistent with that of normal radio pulsars. A magnetized hydrogen atmosphere model, covering the entire star surface, provides a good description of the phase-resolved spectra and energy-dependent pulsed fraction. However, we found that a temperature map more anisotropic than that produced by a dipole field is required, with a hotter zone concentrated toward the poles. By adding two small polar caps, we found that the surface effective temperature and that of the caps are ∼0.1 and ∼0.36 keV, respectively. The inferred distance is ∼3.3 kpc. We confirmed the presence of an absorption line at 0.7 keV associated with the emission from the whole star surface, difficult to interpret as a cyclotron feature and more likely originating from atomic transitions. We searched for pulsed γ-ray emission by folding seven years of Fermi-LAT data using the X-ray ephemeris, but no evidence for pulsations was found. Our results favor the hypothesis that Calvera is a normal rotation-powered pulsar, with the only peculiarity of being born at a large height above the Galactic disk.

We present the 3 mm wavelength spectra of 28 local galaxy merger remnants obtained with the Large Millimeter Telescope. Sixteen molecular lines from 14 different molecular species and isotopologues were identified, and 21 out of 28 sources were detected in one or more molecular lines. On average, the line ratios of the dense gas tracers, such as HCN (1–0) and HCO+(1–0), to 13CO (1–0) are 3–4 times higher in ultra/luminous infrared galaxies (U/LIRGs) than in non-LIRGs in our sample. These high line ratios could be explained by the deficiency of 13CO and high dense gas fractions suggested by high HCN (1–0)/12CO (1–0) ratios. We calculate the IR-to-HCN (1–0) luminosity ratio as a proxy of the dense gas star formation efficiency. There is no correlation between the IR/HCN ratio and the IR luminosity, while the IR/HCN ratio varies from source to source ((1.1–6.5) × 103
L
☉/(K km s−1 pc2)). Compared with the control sample, we find that the average IR/HCN ratio of the merger remnants is higher by a factor of 2–3 than those of the early/mid-stage mergers and nonmerging LIRGs, and it is comparable to that of the late-stage mergers. The IR-to-12CO (1–0) ratios show a similar trend to the IR/HCN ratios. These results suggest that star formation efficiency is enhanced by the merging process and maintained at high levels even after the final coalescence. The dynamical interactions and mergers could change the star formation mode and continue to impact the star formation properties of the gas in the postmerger phase.

The absolute absorption cross section of dangling OH bonds in water ice, a free OH stretch mode by three-coordinated surface water molecules, is derived experimentally as 1.0 ± 0.2 × 10−18 cm2 at 3696 cm−1 for amorphous water at 90 K using infrared multiple-angle incidence resolution spectrometry (IR–MAIRS). The integrated absorption cross section (band strength) of the dangling OH bond at 90 K (1.4 ± 0.3 × 10−17 cm molecule−1 at 3710–3680 cm−1) is found to be more than 1 order of magnitude smaller than those in bulk ice or liquid water. This indicates that a lack of hydrogen-bonding significantly decreases the band strength of dangling OH bonds. The present study also provides average molecular orientations of dangling OH bonds at 10 K and 90 K, because both the surface-parallel (in-plane) and surface-perpendicular (out-of-plane) vibration spectra of dangling OH bonds are quantitatively measured by IR–MAIRS. The intensity ratio of the dangling-OH peaks between in-plane to out-of-plane spectra shows the isotropic nature (random orientation) of the two- and three-coordinated dangling OH bonds in microporous amorphous water prepared at 10 K; however, the three-coordinated dangling OH bonds in nonporous amorphous water prepared at 90 K are dominantly located at the top ice surface and oriented perpendicular to it. These findings provide fundamental insights into the relationship between the structure and optical properties of ice surfaces, and aid quantitative understanding of the surface structure of interstellar ices and their laboratory analogs.

Coleus (Lamiaceae) in Peninsular Malaysia including two new species
Authors: Kiew Ruth , Kamin Imin
Published: December 2021

In Peninsular Malaysia, Coleus is represented by five species. Two, C. hairulii Kiew and C. rafidahiae Kiew, are new species. Both are narrowly endemic and restricted to limestone hills as is C. kunstleri (Prain) A.J.Paton. All three are Critically Endangered. Coleus scutellarioides (L.) Benth., although widespread, is probably not indigenous. It is also a common ornamental, while C. monostachyus (P.Beauv.) A.J.Paton is a recent introduction that has spread rapidly and threatens to become a troublesome weed.

Abstract

Two species of hedgehogs are known to occur in northern part of Africa: the Algerian hedgehogAtelerix algirusand the Ethiopian hedgehogParaechinus aethiopicus. Within each species several subspecies were described based on morphometrical data and pelage coloration, but all these subspecies have enigmatic and unclear definitions. We investigated the phylogeographical history and taxonomy of these two species based on mitochondrial DNA data covering the entire geographical distribution ofA. algirusand the North African distribution ofP. aethiopicus. We also used climatic niche modelling to make inferences about their evolutionary history. Low genetic diversity was recovered in both species. While no phylogeographic pattern was found inP. aethiopicus, two haplogroups were identified withinA. algirus. This could be explained by the fact that continuous high or moderate climatic suitability occurred throughout most of the Saharan desert since the LGM (Last Glacial Maximum) for the first species, while during the LGM there were several disconnected areas of high climatic suitability forA. algirus: one in South-West Morocco, one at the coastal Moroccan-Algerian border and one in Tunisia-coastal Libya. Our genetic results confirm thatA. algirusrecently colonized Spain, Balearic and Canary Islands, and that this colonization was probably mediated by humans. Suitable climatic conditions occurred throughout most of the Southern and Eastern Iberian Peninsula during the last 6,000 years which could have favored the spatial expansion of the Algerian hedgehog after its arrival in Europe. According to our molecular results subspecific recognition within North Africa is unwarranted for both species.
