AbstractSeeds, fiber samples, and boll parts recovered from 4 pre-ceramic sites in the Ancon-Chillon area of Peru were compared with those of living forms, both wild and cultivated, collected from the coastal areas of Ecuador and Peru. All the living forms belong to the species, Gossypium barbadense L., and it was concluded that the archaeological cotton belonged to this same species. Chocolate and reddish-brown colored fibers recovered from 4 sites (Tank, Punta Grande, Pampa, and Camino) and encompassing a time sequence from approximately 2500 B.C. to approximately 1750 B.C. resembled closely those still to be found in present-day cultivars in coastal Peru and Ecuador. On the other hand, certain characteristics exhibited by the archaeological material (small beaked bolls, fuzzy seeds, narrow fiber diameter) resemble more closely those of present-day wild forms. Seed size and fiber diameter show progressive increases from the older to the more recent levels. The finding of (1) chocolate colored fibers and (2) a single boll with a fringeless nectary (both characteristic of G. barbadense) among the archaeological samples suggests that they represent a very early stage in the domestication of that species.

Andornaktálya-Marinka is among the several Palaeolithic archaeological sites in the region of Eger, on the foothills of the Bükk Mountains, North-Eastern Hungary. It is situated on the top of a 234 m high elevation located between the villages Andornaktálya and Ostoros. The site was discovered in 2014 by Ferenc Cserpák. Surface collections yielded by several field surveys show two kinds of archaeological material: one is signified mostly by a bifacial-like industry made of quartz porphyry (metarhyolite), while the other one is abundant in blade-like pieces made of Silesian erratic flint. The main aim of the excavation carried out in summer 2018 was to obtain stratigraphic information about the position of the industries, as well as to characterize the quaternary sediments covering the hilltop. The artefacts unearthed in the five trenches occurred in a depth of 60 to 80 cm in a brown chernozem-like layer.

This study is part of a larger research study (doctoral dissertation), in which a comparative study with adolescent samples is done: 50 anorexic restricting patients (ANP), 50 patients diagnosed with depression (DP) and 50 non patients (NP). The proposed objective is two-fold: 1) To try to clarify the existing relationship between Anorexia (AN) and Depression (D), investigated from diverse disciplines but without conclusive results. 2) To detect in the ANP personality different traits from those of other groups, which should, if possible, allow to detect them at an early stage for an adequate prognosis. The current article presents the Rorschach findings in relation to the cognitive functioning of the ANP. In them, the following has been detected: (1) An information processing similar to that of the other groups, even with a more complete (L ≤ .99), more complex (DQ+↑) and better discriminated (Zd↑) grasp of the stimulus; (2) Mediating processes very similar to those of the other groups, sharing with them the perceptive maladjustments (X–%↑) and an excessive individualism (Xu%↑); (3) A clearly differentiating ideation disorder. Definitely, the ANP use predominantly ideation (M↑), but their thought, usually well-adjusted (MQo↑), presents eventual operations of delusional type (MQnone↑). Above that, their thinking is marked by a great passivity (Mp↑), which makes them more vulnerable to accept ideas without criticizing them and it results in a very inefficient thinking, which spins around these concepts without finding solutions, entering into a sort of ruminating which is completely unproductive. The differences toward the obsessive pathology are established. The discriminant analysis conducted with all the Rorschach variables that resulted as significant throughout the research, provides quite a consistent function which discriminates the ANP: MQnone↑, Mp↑, FD↓, Ma↑, MQo↑, AdjD↑, Sum H↑, (H)↑. Based on this we can understand that these adolescents, being in a developmental period of big changes and disorientations in relation with their own image, confronted with life events, and possibly starting off with some biologic vulnerability: (1) Due to the alterations of their ideation, accept without criticism (Mp) irrational ideas dominating in our culture, in which slimness appears as the only model, synthesis of intelligence, beauty and success; remaining captured in this type of mental activity (MQnone), which they cannot escape nor criticize (Mp), despite they reason adequately on other topics (MQo); (2) Their alterations of self-perception [(H)] make them hide themselves in a fantasized image, which is the axis of their interests and the only thing that really matters to them; (3) The resources they have to decide on behaviors and to finish these deliberately (AdjD), and their scarce tendency to the introspection (FD) lead to their decision of not eating, based on distorted and passively accepted thinking, which has great power and thus, so difficult to modify. Finally, based on the Rorschach data obtained, the hypothesis of a personality disorder as underlying pathology is pointed out.

New energy vehicles(NEV) as a new thing for sustainable development, in China, on the one hand has faced the rapid expansion of the market; the other hand, for the new NEV users, the current NEVs cannot keep up with the degree of innovation. This paper demonstrates the reasons for the existence of this systematic challenge, and puts forward the method of UX research which is different from the traditional petrol vehicles research in the early stage of development, which studies from the user's essence level, to form the innovative product programs which meet the needs of users and being real attractive.

A total of 15 RT-PCR confirmed COVID-19 patients were admitted to our hospital during the in-itial outbreak in Taiwan. The average time of virus clearance was delayed in seven patients, 24.14 ± 4.33 days compared to 10.25 ± 0.56 days post-symptom onset (PSO) in the other eight pa-tients. There was strong antibody response in patients with viral persistence at the pharynx, with peak values of serum antibody 677.2 ± 217.8 vs. 76.70 ± 32.11 in patients with delayed versus rapid virus clearance. The patients with delayed viral clearance had excessive antibodies of compromised quality in an early stage with the delay in peak virus neutralization efficacy, 34.14 ± 7.15 versus 12.50 ± 2.35 days PSO in patients with rapid virus clearance. Weak antibody re-sponse of patients with rapid viral clearance was also effective, with substantial and comparable neutralization efficacy, 35.70 ± 8.78 versus 41.37 ± 11.49 of patients with delayed virus clearance. Human Cytokine 48-Plex Screening of the serial sera samples revealed elevated concentrations of proinflammatory cytokines and chemokines in a deceased patient with delayed virus clear-ance and severe disease. The levels were comparatively less in the other two patients who suf-fered from severe disease but eventually survived.

ABSTRACTPolycrystalline SiGe (poly-SiGe) film growth by reactive thermal CVD with a gaseous mixture of Si2H6 and GeF4 was investigated on various substrates such as Al,Cr, Pt, Si, ITO, ZnO and thermally grown SiO2.In Ge-rich film growth, SEM observation in the early stage of the film growth revealed that direct nucleation of crystallites took place on the substrates. The nucleation was governed by two different mechanisms: one was a heterogeneous nucleation on the surface and the other was a homogeneous nucleation in the gas phase. In the former case, the selective nucleation was observed at temperatures lower than 400°C on metal substrates and Si, where the activation of adsorbed GeF4 on the surface played a major role for the nuclei formation, leading to the selective film growth.On the other hand, the direct nucleation did not always take place in Si-rich film growth irrespective of the substrates and depended on the growth rate. In a growth rate of 3.6nm/min, the high crystallinity of poly-Si0.95Ge0.05in a 220nm-thick film was achieved at 450°C due to the no initial deposition of amorphous tissue on SiO2 substrates.

The time course of the recovery of subjective visual horizontal (SVH) after unilateral vestibular deafferentation by intratympanic instillation of gentamicin was studied. Six patients who underwent intratympanic gentamicin instillation therapy for Meniere's disease (1 man and 5 women, 32 to 69 years of age) were enrolled in this study. For comparison, SVH in 23 healthy subjects (12 men and 11 woman, 23 to 48 years of age) was also measured. The mean ± SD of SVH in healthy subjects was 0.0 ± 1.1 deg. All of the 6 patients showed significantly deviated SVH toward the injected side-down at the early stage after the therapy. Although one patient showed recovery of SVH to the normal range 25 days after the injection, the other patients required more time for recovery. Three patients did not show recovery to the normal range after 1 year. On the other hand, spontaneous nystagmus observed using an infrared CCD camera in total dark disappeared after 35 days (median). Patients who had normal vestibular evoked myogenic potentials before the therapy showed a tendency of delay of recovery of SVH. The reasons why the recovery of SVH took longer than the disappearance of spontaneous nystagmus are discussed in this report.

Community has been much of a striking terminology these days when associated with heritage management. Communities living nearby heritage sites, while at one hand are agents of conservation, on the other hand are sources of destruction in heritage sites and agents of risks. As such, this research unfolds the contested roles of local people for taking ownership of heritage management, understanding heritages, transmitting oral intangible values and valuing destination image at Kichakbadh Province -1, Nepal. The research, aimed at studying heritage management issues around the site has been supplemented by multiple field visits, numerous questionnaires and interviews with locals, visitors and experts. This article chiefly deals with the second phase of author’s exploration carried out on an annual fair called Maghe Purnima at Kichakbadh in 2019. While science of archaeology restricts human activities in conserved places, large fairs are held in archaeologically sensitive areas of Kichakbadh posing threats to archeological wealth there. To utter dismay, archaeological crimes are still common in many sites at Kichakbadh. Multiple field-visits, questionnaire with the stakeholders, visitors and community during the fair reveal that minimal traces of community and state level endeavors to conserve the sites do not meet the vast rescue requirements that Kichakbadh is actually in need of.

Although in a majority of cases, autistic children face difficulties communicating verbally, the valid diagnostic classifi cations do not identify them as the main symptoms of the disorder. The adoption of such a position has been supported by results of (mainly behavioural) research, which imply that language and speech development in the autism spectrum disorder (ASD) is extremely variable and individually diversifi ed and the observed delay of its development is not unique to autism. On the other hand, the research conducted by means of neuroimaging methods shows that an atypical structure and activity of Broca’s and Wernicke’s areas, which are important for language processes, exist in the ASD. A weak structural and functional connectivity in the arcuate fasciculus, which connects these structures, has also been discovered. It is assumed that the changes arise from neurodevelopmental irregularities occurring at an early stage of foetal life and their causes are probably genetic. This study characterises speech development disorders and atypical brain development in autism referring to results of both behavioural and neuroimaging research.


Our healthcare is very much important to lead a peaceful and honest life. If any health issue occurs, we need to go to the hospital and consult the doctor for the very minor problems. our healthcare chatbot is developed to help the people to predict their health issue early at home before they visit the doctor or hospital for the mi nor problems. For the minor issues we are spending lots of costs. The healthcare chatbot is design to reduce such costs and also its improves the efficiency of the medical healthcare. There were many chatbots available they act as a reference for the patient to know more about their health issue. The healthcare chatbot is something different from the other chatbots which predicts the diseases by using symptoms and gives the doctor details to consult the doctor. The healthcare chatbot is developed by using AI in the text to text conversation mode. The user who knows only to write and read can use this chatbot for their minor issue. In this healthcare chatbot, the system predicts the diseases based on the symptom given by the user using the pattern concept in AIML algorithm. The system also predicts the prescription and also give the doctor details to the user based on the diseases predicted for their symptom given. By using this healthcare chat bot people will know the minor diseases at early stage with no costs. Whenever the patient or user gets the time they will consult doctor for their health issue. This will make people to know more about their health issue anywhere at any time.

No archaeology data has been published from the Stonehenge region of central western Queensland.  Indeed the only archaeological activity carried out in the area to this point in time, has been sporadic forays by one or two consultants, leading to a restricted amount of information being available for public comment.  The following paper begins the process of addressing this situation by discussing archaeological sites found during the field component of a consultancy in the Stonehenge-Longreach district.  General interpretations are offered regarding prehistoric human behaviour and the paper also highlights some problems associated with the interpretation of archaeological material in the field.
