The recent satellite communication systems tend to employ Millimeter wave frequencies to meet the ever increasing demands of capacity. Keeping view of the socio-economic and geographic diversities of India, estimation of attenuation due to different atmospheric components at mm-wave earth-space links in different parts of Indian region becomes very important. The development of channel model at mm-wave bands for predicting the total attenuation along earth-space paths caused by rain, clouds and atmospheric gases is the main objective of the current study. The use of the existing models from various propagation campaigns and ITU-R model are used along with the experimental data for effective means of prediction of total attenuation at mm-wave band of frequencies. The instantaneous frequency scaling is done in the present study to predict tropospheric attenuation caused by different atmospheric components at higher frequency bands from the lower band data.


The Turkish anthroponymy, as a product of cultural and linguistic characteristics, portrays the cultural and national identity of its people accurately. If we exclude Arabic and Persian influences and traces in the Turkish onomastics, it can be established that authentic Turkish names mirror the cultural heritage of its nation, putting cultural features of different periods of Turkish history on display. Most of Turkish names stand for any common noun in its unmodified form. Apart from nouns, first and last names can also take the form of different grammatical categories. In order to get the first name, one merely needs to put a capital letter at the beginning of these categories. This linguistic phenomenon can occasionally confuse the translator but it will never cause him to make any crucial errors in the text. However, the nonexistence of grammatical gender in Turkish language, along with the frequent substantivization, can often cause difficulties for translation of texts that contain such names. These difficulties are mostly resolved with the help of context. Nevertheless, there are many situations where it is hard to determine whether a particular name is male or female, which calls for additional effort and research, thus unexpectedly complicating a translator's job. This cultural and linguistic characteristic of the Turkish language, which challenges the readers and translators especially, is one of the main features of the novel  ̋100 ̋, written by Başar Akşan that requires a separate and thorough analysis of its own.


This study was conducted to investigate the effect of using different powers of magnetic field technology (0, 1000, 1500, 2000 gausses) of well water treatment on, egg quality (external and internal properties of egg and Biochemical internal egg composition) of (Brown Lohman classic) layers. A total of two hundred and fifty-six (256) commercial Brown Lohman Classic strain 48 week's age and nearly similar body weight were randomly assigned of commercial-type caged layer divided into four groups of 64 hens for each group, with (8) replicates per treatment. The birds housed in an environmentally controlled building with a density of eight (8) hens per replicate (cage). The results showed that using magnetic water had significantly (P≤0.05) increasing in accumulative results of external egg improving in eggshell thickness, egg shape index, egg soft shell percentage, undesirable egg percentage) in groups that used magnetic water compared with the control group but eggshell percentage and shell strength and broken egg percentage had not affected significantly (P≤0.05) by using magnetic water. Accumulative results of internal egg quality showed a significant increase (P≤0.05) in yolk index, albumen index, albumen high, haugh unit by groups that used magnetic water compared with the control group, also, revealed that yolk percentage and albumen percentage had not been affected significantly (P≤0.05) by different level of magnetic water .Also Results showed that using magnetic water with different powers caused a significant (P≤0.05) increasing in chemical egg composition (egg moisture percentage, protein percentage, calcium and sodium ppm) compared with the control group, Fat percentage and ash percentage decreased significantly (P≤0.05) by all groups that used magnetic water comparing with the control group.


Gilsang Munjado is a kind of drawing realizing auspicious aspirations or dreams which are potential in human-being. The characters with good auspicious signs are Su, Bok, Gang, Ryeong, Jeong, Bu, Gui, and Heui in Chinese letters. They have rich implications such as Longevity, Good Fortune, Good Nature, Fidelity, Wealth and High Status. These characters are written or embroidered in scrolls or folding screens to wish for a fortunate and glorious life, and not only have the purpose of decoration but also have incantational functions. Therefore, this study aims to rebuild a modern image of Korean pictorial patterns. To do this, firstly, the study uses the Korean pictorial ideograph as a cultural archetype, and it analyzes the characteristics of its forms through a theoretical consideration with a literature and empirical artifact analyses. Secondly, it develops a culture based textile which forms a contemporary Korean design as well as the tradition of traditional culture, based on this result. Thirdly, the ultimate aims is to use them to develop fashion cultural products. That is, after the study develops motifs and patterns based on Su-Bok ja which is found most often out of Gilsang Munjado, it produces textile through desktop publishing, and it uses them to make fashion cultural products as household items.


Abstract The Chinese rise to economic and political power at the global level has been at the centre of scholarly and political debates. The purpose of this article will be to analyse the integration of Chinese managers in the Western economy. The methodology will be a bibliography, descriptive, and explanatory, making a comparison between the Brazilian trade and China. The type of literature review is the integrative one, intending to conduct a meta-analysis of the literature and answer specific research questions. The conclusions explore some normative implications of the results of the economy in China and Brazil. On the one hand, China has become a dominant and undeniable shareholder in multiple industries, including the energy sector and R&D with high governmental investments. However, the West appears not to be appropriating its business practices, so the learning process is not fully operationalised.


This article presents the monitoring of water quality by means of wireless sensor technology that is powered by solar energy. The different constituents of water example pH level, turbidity, water level are measured by means of sensors that are powered by solar energy. The information from the sensors are gathered and afterward sent to the cloud server by means of WiFi module. The collected data is further analyzed, shown in visual format in LCD and graphical comprehension is demonstrated via ThingSpeak. In the remote areas, the quality of water is displayed in LCDS. If after analyzing the properties the water quality appears to be negative, necessary steps can be taken.

Abstract. This paper examines the main features of the social production process of condominios fechados across the Lisbon Metropolitan Area. This residential form first appeared in Portugal in the 1980's and spread quickly in the 1990's. The article opens with a preliminary analysis of the development of secured residential complexes, aimed at understanding its specificity and pinpointing the main factors involved in its social production. In this analysis, we do not focus on the Lisbon Metropolitan Area (LMA) alone but rather adopt a broader approach. In the second chapter we describe the research methods used, such as a survey of condominios fechados built in the Lisbon Metropolitan Area between 1985 and 1999, interviews with social actors and content analysis of promotional materials. Finally, we present selected research results and discuss several issues central to understanding the social production of gated housing estates in the LMA, including the importance of foreign modeis, the supply side agency of the real estate market, and the broader social context.


In recent years, frequent occurrence of food safety crisis has seriously affected people's health, which causes widespread concern around the world. To effectively track and trace food has become an extremely urgent global issue. Early warning of food safety can prevent food safety crisis. However, there is still very few automatic tracking systems for the entire food supply chain. In the paper we propose a data mining technique to predict food quality using back-propagation (BP) neural network. Some prediction errors could occur when predicted data are near threshold values. To reduce errors, data near the threshold values are selected to train our system. Special care of threshold values and performance of our proposed algorithm are discussed in the paper.


A 61-year-old man with longstanding persistent atrial fibrillation (AF) since 2010 presented to the clinic, having undergone cardioversion for AF in 2016 and AF ablation (pulmonary vein isolation, posterior left atrium isolation, and cavotricuspid isthmus ablation) in July 2017. He developed atrial tachycardia (AT) a few months after the AF ablation procedure and underwent AT ablation (LA posterior wall) in October 2017. However, he experienced early recurrence, requiring a second cardioversion (for AT) and treatment with dofetilide in 2018. He remained primarily in sinus rhythm until September 2020, when he developed persistent AT again, which recurred after a third cardioversion attempt in early October 2020.

admitted in hepatic coma and died 2 days after delivery. During the first 5 days the infant patient had mild respiratory distress, with radiologic evidence of infective changes in the left lung. Intramuscular penicillin 250,000 units 8-hourly and Kanamycin 7.5 mg 12-hourly, were both given for 5 days. On the 6th day the infant had an apneic attack requiring resuscitation with &dquo;bag and mask.&dquo; During the first ten days there was a tendency for the baby to become hypothermic despite adequate incubator temperature. On day 12 she was noted to look ill and was hypotonic. The anterior fontanelle was bulging and the CSF from lumbar puncture revealed xanthochromic fluid with no white cells; 1,200 red blood cells (RBC) per c mm; total protein 1.65 gm/l; chloride 124 mmot/I and sugar 4.5 mmol/l. No organisms were seen on direct microscopy or grown on culture. No fluid was obtained from the


The second part of the proposed papers (the first part was published in the previous issue of "Ethnomusic") covers detailed history of the ethnographic and folk music col- lection activity of ethnomusicologist Clyment Kvitka and dialectologist Olena Kurylo in 1924th–1926th based on historical information from printed and archival sources. In 1924 the geographical orientation of the corporate expeditions of K. Kvitka and O. Kurylo changed from the Polissya to the Podillya region. In the spring of 1924 they traveled to the Vinnytsia oblast by train to observe live performance of the Easter rituals. Apparently, having done this task, K. Kvitka suggested O. Kurylo visiting the 92 final train's stop village Kamyanka on the river Dnister. From here, they went to the nearby villages, where Moldavians and German colonists lived, thanks to which they were able to study folklore of national minorities. Generally in the expedition they spent three weeks and collected 65 songs. The next trip to Volyn and Podillya was scheduled for summer 1924 to collect materials on the history of culture and historical documents. In early August, Kvitka took a train to Vinnytsia and returned to Kyiv in three weeks, but there is no informa- tion about the collection work done there. Just two weeks later, K. Kvitka (together with M. Hayday) set off again – this time to the Middle Polissya – in Korosten, Zhytomyr and Berdychiv districts, where he recorded 20 melodies. O. Kurylo obviously did not take part in this expedition. O. Kurylo and K. Kvitka returned to the joint expeditions in the following year, going in the summer on their second Podillya "excursion" for a two-week period. They planned to visit Zhytomyr, Berdychiv, Shepetivka, Proskuriv, Kamyanets and Vinnyt- sia districts, and especially towns Slavuta, Teofipol and others. In his list of records for 1925 K. Kvitka mentioned thirty-five recordings of folk melodies from Vinnytsia and Kamyanets-Podilsky regions, but only one of them is known – ballads about a seduced girl in Polish performed by O. Pototska from the Russian Filvarki settlement. In their expeditionary sessions O. Kurylo recorded poetic texts and it allowed K. Kvitka to concentrate on writing down musical notes, in particular, to trace possible performing melodic "variations", which was one of the most characteristic features of his tran- scriptions of that period. In return, dialectologist O. Kurylo professionally wrote folk songs poetic texts, noting semi-phonological features. It is worth quoting the whole transcription made by Kvitka and Kurylo with the author's notes to give a clear idea of the unprecedentedly high scientific level of fixation of folklore material. Collectors continued to explore Podillya in the following 1926, going there to- gether for the third time. Again, K. Kvitka wanted like earlier to watch live Easter rituals for which the time and place were chosen in advance. It was village Kukavka. Such details of K. Kvitka's work with singers as the creation of an atmosphere of respect and friendliness with some encouragement the performers with small treat or small payment seem to be interesting. In general, the expedition lasted a month and a half and was finished at the end of the first decade of June. Apparently, immediately after returning to Kyiv, O. Kurylo moved to Vinnytsia in August. After 1926 O. Ku- rylo no longer took part in joint expeditions as well as K. Kvitka. Apparently, the plan of field research (primarily dialectological) was succeeded, at least in general, and sci- entists focused entirely on the study of the obtained materials, primarily from Podillia. Thus, we only know about the materials collected by O. Kurylo and K. Kvitka in the expeditions of 1922–1926, which were published largely on occasion. The rest of the hard work in five years seems to have disappeared.


Abstract : The primary source of historical loss information is the Fiscal Year Computerized Officer Projection System report. The analysis techniques used were linear regression and Box and Jenkins' time series. The regression models developed for both separation and retirement predictions were very accurate. The FY81 separation prediction was in error by only 1.8% and the FY82 separation and retirement predictions were in error by 16.9% and 2.1% respectfully. Moreover, a modified update procedure was in error by only 9.6% for the FY82 separation prediction. This compares to errors in loss predictions of 1.7% to 79.9% for the currently used models. Although time domain time series models were developed which adequately fit both separation and retirement patterns, both failed to accurately predict either short or long term trends.


Question In patients with out-of-hospital cardiac arrest (OHCA), does inducing therapeutic hypothermia (TH) during cardiopulmonary resuscitation improve survival compared with usual care? Methods Design Randomized controlled trial (RCT) (Rapid Infusion of Cold Normal Saline [RINSE] trial). ClinicalTrials.gov NCT01173393. Allocation Unclear allocation concealment.* Blinding Blinded* (data analysts). Follow-up period Up to hospital discharge. Setting 3 cities in Australia. Patients 1202 adults 18 years of age (mean age 65 y, 74% men) who had spontaneous OHCA and were in cardiac arrest on arrival of emergency medical services, had IV access established, and remained in cardiac arrest after initial resuscitation treatments (defibrillation, IV cannulation, epinephrine administration, and ventilation with 100% oxygen). Exclusion criteria included OHCA due to trauma, suspected intracranial bleeding, hypothermia (<34.5 C), inpatient status, pregnancy, or known nonresuscitation directives. Intervention Cooling with rapid infusion of cold saline, 30 mL/kg up to 2 L by peripheral IV cannula (TH) (n =618), or continuation of usual care (n =580). Outcomes Survival to hospital discharge. Secondary outcomes included death at the scene, transport with return of spontaneous circulation (ROSC), discharge to home, and adverse events. 1206 patients with initial shockable rhythms were needed to detect a 7% absolute increase in overall survival, assuming a 20% survival rate in the usual care group (80% power, =0.05); 2512 patients were planned to be enrolled. Patient follow-up >99.5% of eligible patients (90% of 1324 randomized patients) (intention-to-treat analysis). Main results Enrollment was stopped early because hospitals changed their temperature management in postcardiac arrest patients due to results from another RCT (see Commentary). Compared with usual care, TH reduced the likelihood of ROSC at the scene and increased risk for acute pulmonary edema; groups did not differ for survival to hospital discharge, discharge to home, or death at the scene (Table). Conclusion In patients with out-of-hospital cardiac arrest, therapeutic hypothermia during cardiopulmonary resuscitation did not improve survival to discharge more than usual care. Therapeutic hypothermia during cardiopulmonary resuscitation vs usual care in patients with out-of-hospital cardiac arrest Outcomes Hypothermia Usual care RBR/RRI (95% CI) NNH (CI) Alive at hospital discharge 10% 11% RBR 10% (24 to 35) Not significant Died at scene 51% 45% RRI 12% (0.4 to 26) Not significant Transported with ROSC 34% 39% RBR 14% (0.5 to 26) 18 (10 to 516) Acute pulmonary edema 10.0% 4.5% RRI 124% (44 to 248) 19 (12 to 38) RBI (CI) NNT Discharge to home 8.7% 8.4% 3% (28 to 49) Not significant RBR = relative benefit reduction; ROSC = return of spontaneous circulation; other abbreviations defined in Glossary. RBR, RRI, RBI, NNH, and CI calculated from event rates in article. Commentary Efforts to improve methods for cooling have been under way since 2002, when TH gained acceptance as a treatment for postcardiac arrest patients. Machines that cool patients faster and more precisely have been widely implemented but do not seem to improve outcomes over ice bags (1). Before the RINSE trial, 7 RCTs (n =2369) had compared prehospital TH with cooling on hospital arrival; no study or meta-analysis of these trials has shown any patient-important benefit (2). The RINSE trial evaluated the effect of even-earlier coolingbefore ROSCbut again, found no benefit. The RINSE trial brings the number of patients enrolled in RCTs to >3500, and it is time to accept that prehospital cooling is unlikely to be beneficial. Given the now-strong evidence that TH at 33 C offers no benefit over controlled normothermia 36 C (3), the biologic plausibility of benefit from earlier aggressive cooling becomes questionable. If colder is not better in the first place, then colder sooner is irrelevant. Substantial evidence from RCTs shows that prehospital TH offers no benefit over delaying temperature control until hospital arrival. Moreover, the RINSE trial suggests that prehospital cold saline infusions may actually be harmful. Ardent supporters of TH will point out that RINSE was stopped early when some area hospitals changed their postarrest temperature targets from 33 C to 36 C because of the results of the TTM trial (3). Also, previous studies of prehospital cooling were unable to control inpatient TH, potentially biasing their results toward no effect. Despite these issues, the totality of TH research to date does not show that efforts to cool patients earlier or more aggressively improves patient outcomes.


Background. Salt Lake City, Utah has seen a continuing resurgence of rheumatic fever (RF) since 1985. Methods. emm genotyping and multilocus sequence typing of streptococcal isolates from periods of increased RF activity were performed. Results. Multiple genotypes were present during 1985 and 1998, two peak years of RF activity, and in 1992, a year with reduced RF activity. emm3 and emm18.1 were present in 1985 and 1998, but not in 1992. Two other emm types, 12 and L28, were significantly elevated in 1998 (a peak RF year) over 1992 (a non-peak RF year). Allelic profiles for the emm3 and emm18.1 isolates exhibited clonality. Conclusions. During years of increased RF activity multiple emm types, including emm18.1 and emm3, were circulating in the community. During a year of decreased RF activity, emm3 and emm18.1 genotypes were absent. The clonality of the emm3 and emm18.1 types suggests that specific clones of both types are important in the resurgence of RF during these peak years. Two other genotypes, emm12 and emmL28, may also be associated with the persistence of RF in the Salt Lake City, UT area.


Stressful life events have been associated with increased risk for development of schizophrenia and play a pivotal role in its psychopathology. Genes related to stress response, such as FKBP5 gene associated with hypothalamic–pituitary–adrenal (HPA) axis, modulate brain response to childhood trauma and determine individual susceptibility for development and course of psychosis. It this review we provide an overview of FKBP5 gene role in human neurophysiology, its association with HPA axis and its role in stress response system in animals and humans. Moreover, we took a closer look on the studies showing the interaction between FKBP5 gene and stressful life events in the pathophysiology of schizophrenia. We explain how interactions between trauma and FKBP5 gene polymorphisms contribute to development of the disease, severity of psychotic symptoms and cognitive disturbances. We also discuss epigenetic modifications that may contribute to altered HPA axis reactivity to stress entailing higher risk for development of psychosis. Considering the pivotal role of FKBP5 gene in physiopathology of schizophrenia we discuss a possible use of new therapeutic agents that may influence HPA axis activity related to the FKBP5 protein especially in individuals exposed to early trauma.


Bitterling fishes lay their eggs on the gills of living freshwater mussels and are valuable models in behavioural and evolutionary ecology. We used morphological and genetic data to resolve the taxonomic relationships of bitterling in Europe. Previous studies have suggested the European bitterling is either a single species with a wide but discontinuous geographic distribution, or a complex of species. Morphometric and meristic data identified differences between three putative species; with a clear distinction between the eastern Asian Rhodeus sericeus, western European bitterling Rhodeus amarus, and colchian bitterling, Rhodeus colchicus. Polymorphism in the mitochondrial DNA control region was predominantly due to insertion/deletion events, making phylogenetic inference difficult, but the single haplotype found in R. sericeus populations was detected at low frequency (one of 24 individuals) in R. amarus and R. colchicus populations. Eight control region haplotypes were found in R. amarus populations, which were distinct from the two haplotypes in a R. colchicus population. Cytochrome b data produced a phylogeny with strongly-supported differentiation between a clade of two R. sericeus haplotypes and a clade of six R. amarus/colchicus haplotypes. The star-like topology of the R. amarus/colchicus haplotypes in a minimum spanning network suggested a rapid radiation in this clade. Our results are consistent with an hypothesis of relatively ancient divergence of R. sericeus from R. amarus/colchicus and more recent and rapid differentiation between R. amarus and R. colchicus. © 2008 The Linnean Society of London, Biological Journal of the Linnean Society, 2008, 95, 337–347.


This chapter grapples with questions concerning the development of the early Islamic palace and the ?princely cycle.? It focuses on the wall paintings of the ḥarīm in the palatine complex at Samarra, founded in 836 by the Abbasid caliph al-Muḥtasim. It also focuses on strategies for studying these paintings: first, on the position of the Samarra paintings in Abbasid art and second, on their broader implications for Abbasid art and their role in the formation of early Islamic art. The chapter reconsiders the dominance of Eastern trajectory and destabilizes altogether the East-West binary for the study of early Islamic art. It suggests a more holistic approach that engages East and West through a discourse of cultural exchange and the creation of a local Iraqi style. In this way, a far more integrated scenario of dynamic networks of interaction and connections will emerge, linking East and West, past and present. Keywords: ḥarīm; Abbasid art; early Islamic palace; East-West binary; Eastern trajectory; Iraqi style; palatine complex; princely cycle; Samarra wall paintings


Two synthesis schemes for obtaining new derivatives of 5-hydroxy-1,3,6-trimethyluracil with fragments of protected natural amino acids are proposed. Synthesis includes two ways of obtaining products – chlorohydride, consisting of the protection of amino acids with phthalic acid and further production of chlorohydrides with their subsequent condensation in methylene chloride with uracil derivative, as well as carbodiimide, with tert-butoxycarbonyl protection of amino acids by amino group, also carried out in methylene chloride in the presence of a water-removing agent N,N'-dicyclohexylcarbodiimide. Both methods of placing protective groups in amino acid molecules are described. New compounds were obtained with yields of 65-98%. Also, by the method of N-alkylation with ethylene chlorohydrin, a linker was introduced into the 6-methyluracil molecule with subsequent separation of N1- and N3-derivatives. The reaction was optimized, and the ratio of reagents was revealed, at which the highest yield of the product alkylated at the N3- position is achieved. Successful attempts to attach amino acid fragments to the resulting N3-(2-hydroxyethyl)-6-methyluracil during boiling in ethyl alcohol are described. Due to the high biological activity of all the starting substances, the authors predicted the presence of possible reaction products. The article presents the results of studies of the antiradical (antioxidant) activity of 6-methyluracil derivatives based on the inhibition of the free radical 2,2-diphenylpicrylhydrazine by solutions of specified compounds with different concentrations. It was found that the synthesized conjugates, in particular N3-(2-hydroxyethyl)-6-methyluracil with the amino acid methionine attached via a linker, have increased values of the specified activity in comparison with the initial 6-methyluracil, which makes it possible for their further study. The newly obtained compounds were characterized by the methods of 1H and 13C nuclear magnetic resonance. For citation: Khazimullina Yu.Z., Gimadieva A.R.

Purpose – This paper aims to show that simple geometry‐based hp‐algorithms using an explicit a posteriori error estimator are efficient in wave propagation computation of complex structures containing geometric singularities.Design/methodology/approach – Four different hp‐algorithms are compared with common h‐ and p‐adaptation in electrostatic and time‐harmonic problems regarding efficiency in number of degrees of freedom and runtime. An explicit a posteriori error estimator in energy norm is used for adaptive algorithms.Findings – Residual‐based error estimation is sufficient to control the adaptation process. A geometry‐based hp‐algorithm produces the smallest number of degrees of freedom and results in shortest runtime. Predicted error algorithms may choose inappropriate kind of refinement method depending on p‐enrichment threshold value. Achieving exponential error convergence is sensitive to the element‐wise decision on h‐refinement or p‐enrichment.Research limitations/implications – Initial mesh siz...


The 10 μm scale patterned SiO2 films with excellent insulating quality has been directly deposited by laser chemical vapor deposition projection printing. Leakage current through the SiO2 film was kept within permissible limits for large scale integration (LSI) functioning. This new local insulating scheme substantially extends the potential of laser direct writing circuit restructuring technology, such as in locally insulating two crossing interconnections on LSIs.


Henna plant belongs to continental oases where water shortage constitutes the essential limiting factors of its agricultural production. Lawsonia inermis L. (Lytraceae) is often exposed to severe drought stress in Gabes; a Tunisian arid region. The present study was carried out to evaluate the impact of water stress on the morphology of Tunisian henna plants. Thus, an experiment of four months was carried out under greenhouse at the Institute of Arid Region in Medenine, Tunisia. Henna was exposed to three different irrigation regimes, whereby the plants where irrigated to field capacity (control, T0), 50% of the control (moderate stress, T1) and 25% of the control (severe deficit irrigation, T2). Results showed that, leaf area (LA), leaf number and stem length of henna, decreased in response to the studied stress. The effect of water stress was clearly observed on those parameters. Moderate drought (T1) did not damage henna morphology, and the plants grew better than without water limitation (T0). Furthermore, the water stress-typical responses were shown as time and severity dependent in all the measured parameters. Indeed, lowest water availability treatment (T2) induced significant decrease in total number of leaves, as well as reductions in LA. Under this severe water stress (T2); LA was reduced by 65.79%, compared to control, at 60 days after the initiation of the bioassay. Stem length decreased significantly in the most severe water stress, this reduction was about 44%. Globally, we conclude that henna plant growth decreased progressively to long-term water limitation.

Abstract : Over the past several decades, lawmakers in the United States have responded to the drug epidemic with tougher laws and longer sentences in an attempt to deter drug use. The resulting increase in drug cases has seriously overloaded judicial dockets creating a need for reasoned alternatives. In 1992, the Drug Policy Research Center conducted a drug policy seminar game involving Florida public officials that anticipated this increase in cases as well as the need to provide drug abuse treatment within the criminal justice system. Players in that policy game focused, as we are doing today, on the need to provide criminal offenders with drug abuse treatment as an alternative to incarceration. This emphasis was consistent with our drug policy modeling work that indicated treatment may well be a more cost-effective way to spend additional funds intended to reduce cocaine use than other options, such as domestic enforcement, interdiction, or source country control.


A pulsed Nd:YAG Laser was used to evaporate solid targets of KTiOAsO 4 (KTA) at power densities of 0.6 to 2.0×10 9 W/cm 2 . KTA thin films were deposited on glass, Si (100). After proper annealing treatment, single phase, (orthorh-ombic) polycrystalline KTA thin films were obtained. Some propitious of these thin films were also examined.


As the followup to our previous paper, multicomponent hydrogen-donating hydrocarbons derived from petroleum (HHAP) were oxidized at 160 °C in air for 30 h compared with a conventional diphenylamine type antioxidant (Stealer), and the following results were obtained:  (1) Judging from the changes in the dissipation factor, carbonyl absorbance by IR, acid value, and oxygen content by elemental analysis, HHAP was barely oxidized under these conditions, although n-paraffin wax was clearly oxidized. (2) Small amounts of oxygen-containing compounds (0.5 wt % in oxygen content), which are acidic materials but not carbonyl compounds, were formed from Stealer under these conditions. (3) In addition to the test results reported in our previous paper, it was reconfirmed by the humidity tests that the oxidation of n-paraffin wax was superbly inhibited by the addition of HHAP, and the dissipation factor was kept low during the humidity tests. With regard to why HHAP was not oxidized under these severe conditions, it w...


Relationships to 15N abundances have been found in aridity, rainfall, soil age and latitudinal gradients across large spatial and temporal scales and patterns at intermediate spatial and temporal scale remain unclear. An investigation on 15N abundances at intermediate spatial and temporal scale was conducted in a series of successional fields (Blandy Experimental Farm) in northern Virginia. Foliar and soil samples were collected from these fields in mid‐summer 2004 and 2005. The results showed that foliar δ15N signatures decreased as successional age increased at both the plant community and species levels. There were also significant decreases in soil δ15N as succession proceeded. These results provide a clear example that δ15N signatures in certain ecosystems, like an early successional field, could change significantly at time scales within human lifespans and such dynamics should be considered when modeling δ15N spatial patterns.


The metastable particles in an Al–Zn–Mg–Cu alloy have been examined at atomic-resolution using high-angle annular dark field (HAADF) imaging. In under-aged conditions, thin η′ plates were formed with a thickness of seven atomic planes parallel to the {111}Al planes. The five inner planes of the η′ phase appear to be alternatively enriched in Mg and Zn, with two outer planes forming distinct Zn-rich interfacial planes. Similar Zn-rich interfacial enrichment has also been identified for the η phase, which is a minimum 11-plane thick structure. In rare instances, particles less than seven planes were found indicating a very early preference for seven-layer particle formation. Throughout the aging, the plate thickness appears constant, while the plate radius increases and no particles between 7 and 11 planes were observed. Based on the HAADF contrast, our observations do not support the η′ models previously set forth by other authors. Clear structural similarities between η′ and η were observed, suggesting that drawing distinctions between η′ and η phases may not be necessary or useful.


ABSTRACT The paper presents the first attempt to apply a multiple criteria approach to map ecological-inclusive business models and to structure their main features, in terms of sustainable development. Ecological-inclusive business models are presented in this study, and 15 cases pertaining to agro-food organisations located in Sub-Saharan Africa are considered. These companies simultaneously deliver positive social and environmental value, and confirm a well-established market presence. As far as social value is concerned, the companies included in the sample use a Bottom-of-Pyramid approach, involving low-income customers and/or low-income business partners. As for environmental value, all the analysed companies implement frugal innovation or sustainable exploitation of natural resources in the afro-food sector. One of the results that has been achieved is that of disentangling the complexity behind a triple bottom-line business model through a multidimensional analysis framework that identifies the aspects that play a fundamental role in ecological-inclusive business models. An evaluation model and the application of a multiple criteria outranking method are proposed as examples of how some criteria, such as the extent of socio-environmental concerns, strategy orientation and value of partnerships can be used to compare, rank and/or select business models to facilitate decision makers. This work presents the results of an interdisciplinary study on the social entrepreneurship field of knowledge.


In this article, earlier versions of which were presented at the IVR World Congress in 2019 and in graduate student workshops at the University of Pennsylvania, the author offers a critical look at the existing definition of a refugee in international law, in particular, in the 1951 Convention relating to the Status of Refugees. The Convention recognizes a well-founded fear of persecution for reasons of race, religion, nationality, membership in a particular social group or political opinion as a condition for a person to be granted refugee status. However, this leaves significant gaps in the protection of persons fleeing indiscriminate or generalized violence or harm, although such people today constitute a significant proportion of those forced to move from their country of nationality. The author emphasizes that within some regions and countries there are legal instruments capable of bridging these gaps (the 1969 Organization of African Unity Convention on the Specific Aspects of Refugee Problems in Africa, the 1984 Cartagena Declaration on Refugees, as well as temporary protection in the EU and the US), but the UN Convention continues to be deficient in this regard.
The author proposes to correct these shortcomings by applying the "needs-first" approach, which understands refugees as all displaced persons fleeing sufficiently serious threats. The author presents her own definition of a refugee as "any person with a well-founded fear that their fundamental human rights are urgently threatened; who would have no recourse to their home government, even if appropriate international assistance were available; and whose interests can only or best satisfied by means of refugee – that is, by means of protection from a political authority that is not their own, usually in the form of asylum within the territory of that country."
The author acknowledges that her proposed "needs-first" approach is not without its drawbacks, and the main challenge in its implementation is to avoid becoming a purely humanitarian measure and to preserve the political identity of the individuals who are fleeing the threat to countries not of their nationality.


This study aims to clarify how the room form and other factors have effects on indoor thermal environment and find out the thermal environment characteristics of models of main rooms such as a living room, in contemporary houses in Hokkaido, a cold climate area in Japan. We extracted eight basic form prototypes of modern houses in Hokkaido by their spatial dimension and the way of responding to the outside. In addition, we analyzed alternates that were changed from prototypes respectively and combinatorially in terms of building performance and living style. A PASSWORK design tool was used in this study to calculate the air conditioning load of each model. The present study has demonstrated the thermal environment characteristics of main room models of contemporary houses in Hokkaido and suggested the possibility to make an intimate relationship between indoor and outdoor spaces by using large windows in houses in cold climate areas.

We introduce modifications of an existing spectral dichotomy algorithm [6] with respect to a circle for general regular matrix pencils. The modifications result in a cost-effective algorithm, mathematically equivalent to the original one, but six times less expensive. The algorithm approximates iteratively the spectral projector onto the right deflating subspace associated with the eigenvalues inside/outside the circle as well as a criterion to ascertain its numerical quality. We also show how to approximate the left projector from the algorithm without any extra work. Effective stopping criteria for the algorithm are discussed. Numerical examples which illustrate the theory are presented.


For decreasing the noise of turbo-machineries, making clear the generation mechanism of fluid-dynamic noise is important and an air flow having quiet noise is very useful for the study of aerodynamic noise. A "Quiet Flow Wind Tunnel", whose measuring section is in the annechoic chamber, has been developed and established. The maximum velocity of air flow from the nozzle with a section size of 400 mm×400 mm is 42 m/s and its turbulence is less than 0.5 %. The noise levels around the measuring section are less than 48 dB(A) at a velocity of 35 m/s. By using this facility, further studies have been made, "vortex sound from crossing two cylinders", "flow-noise from finned-tube bank", "noise from ventilating-gallery", "noise of inner flow in straight ducts" etc.. It has been recognised, through these experiments, that this facility can measure both phenomena of fluid-dynamics and acoustics at the same time although these are still impossible by usual wind tunnels.


ADSTRACT A continuous system was designed to agglomerate micro-powdered salt (Na CI) into a porous, open structured agglomerate of greater size than the or-iginal individual salt particles. The effect of design variables on the final size distribution, shape, surface characteristics, density, and strength of the agglomer-ated salt were studied. The operating variables studied were the amount of moisture added to the dry salt, the feed rate of dry salt to the system, and the rotational speed and length of the agglomerating drum. The operating variables were evaluated with respect to weight mean diameter and size distribution of the final agglomerated product, and moisture content of the moist agglomerates. The weight mean diameter and size distribution were independent of the rotational speed, the length of the agglomerating drum, the retention time of the moist salt in the agglomerating drum, and the feed rate of the dry salt. The weight mean diameter and size dis-tribution were dependent on the amount of water present in the moist agglomerates for the moisture ranges and material studied. The strength of the agglomer-ated salt particles were related to the amount of water added to the powdered salt.


Results of the distant earthquakes records analysis and P-receiver function inversion provide valuable information on the distribution of S-wave velocity in the crust and upper mantle and the geometry of seismic boundaries. The developed approach with a sufficiently dense arrangement of seismic stations is useful for solving fundamental problems of studying the structure and formation of the Earth and in identifying promising areas in the search mineral deposits.


Travel time estimation is an important aspect for the traffic flow guidance system. In this paper, based on analysing several methods to estimate the travel time ,we apply Kalman filtering to establish a new model, which can predict the travel time using detected traffic volume on the basic link in the urban transportation networks. In the meantime, we also briefly discuss the prediction results.


The nonlinear vibration of finite-length beams on the Winkler foundation subjected to harmonic lateral loads is investigated in the present paper.Based on the Winkler foundation model and the Euler-Bernoulli beam theory,the nonlinear motion equation of the finite-length beam on elastic foundation is derived.The approximate solution of the finite-length beam for the case of the 1/3 sub-harmonic resonance is obtained by using the Galerkin method and the multi-scale method.To illustrate the characteristics of the 1/3 sub-harmonic resonance,the effects of the slenderness ratio,modulus of elasticity,stiffness coefficient of foundation,damping coefficient and beam density on the frequency-response curves of the finite-length beam on the Winkler foundation are studied.The effect of the 1/3 sub-harmonic resonance on the actual dynamic response of this system is analyzed with the contrast to the non-resonant situation.The numerical results show that the excitation amplitude has significant impact on the 1/3 sub-harmonic resonance region;the resonance of the finite-length beam on elastic foundation will not appear when the damping coefficient or the stiffness coefficient of foundation is greater than a certain value;the 1/3 sub-harmonic resonance significantly increases the displacement of the stationary response.


The invention relates to a corrugated sheet for a plate air cooler. The ripple of a ripple area of a heat transfer sheet consists of transverse ripples formed by a plurality of minimum unit ripple modules and longitudinal ripples formed by a plurality of minimum unit ripple modules; each minimum unit ripple module consists of two stripped bourres and two stripped embosses which have channel-sections; the centers of two stripped bourres and two stripped embosses form four apex angles of a rectangle; and each line and each row of the bourres and embosses form a stripped bourre and a stripped emboss respectively. The corrugated sheet has the advantages that: 1) for the ripple of the heat transfer sheet, the transverse ripples and the longitudinal ripples formed by the minimum unit ripple modules form the ripple that the stripped bourres and the stripped embosses are arranged at intervals in a crossed way, so that the flowing direction of fluid can be changed continuously and is rotated and twisted; therefore, the coefficient of heat transfer is greatly improved; and 2) the stripped bourres and the stripped embosses which are arranged sequentially are different from longitudinal axes of the heat transfer plate, and a new balance between reduction of flow resistance and achievement of a good heat transfer effect is achieved.


The present invention relates to a pharmaceutical composition for preventing or treating hair loss, containing components extracted from chestnut burr. According to the present invention, the pharmaceutical composition for preventing or treating hair loss containing the components extracted from chestnut burr does not cause adverse effects when used in hair loss therapies, provides excellent therapeutic effects on hair loss even in a short period of time, and brings reduction in costs for hair loss treatment within a short amount of time. By containing the components extracted from chestnut burr, the pharmaceutical composition can be applied to treatment agents for hair loss such as shampoo, cosmetic products, or scalp conditioners.


This paper presents an efiective analysis method for EBG reducing patch antenna coupling. A couple of coaxial probes are used to analyze the mutual coupling reduction range of patch antenna arrays loaded with EBG in this method. Conventional FDTD/PBC algorithm for EBG structures is appropriate only in inflnite ground plane and substrate. The gained frequency band-gap by using the algorithm can not be directly used in flnite ground plane because of the edge efiects. While the proposed coaxial probe method is valid not only in inflnite ground plane and substrate, but also for flnite ground plane. The method is more suitable for real environments. In order to validate the described method, a two-element microstrip patch antenna array is fabricated and measured. The experimental results are in good agreement with the theoretical data obtained by using the proposed method.


Diabetes requires a continuous and accurate control in blood glucose level, since this will disturb insulin generation and consumption in the body. As a consequence, blood glucose level will increase. In this paper, RBF neural network controller and Palumbo model are proposed for robust control of the blood glucose level in diabetic patients in the presence of several disturbances and parametric uncertainty. The proposed controller is designed based on Palumbo model. The structure of the proposed controller is suitable for constructing insulin injection pumps in a closed loop of diabetes. The RBF neural network will make the proposed controller robust against disturbance and parametric uncertainty. Results imply that the proposed controller has a suitable performance in terms of disturbance rejection due to eating and doing exercise. Moreover, the proposed controller shows a good performance against changes in diabetic patient's body conditions.


The widely spread iCub humanoid robot has proved to be able to walk straight forward by means of an offline pattern generator, which did not allow for online adjustments and interactions. In this paper, we present a closed-loop control framework based on a Nonlinear Model Predictive Control pattern generator with feedback at the Center of Mass (CoM) position. This framework allows us to extend the walking capabilities of iCub to different walking directions, such as curved, sideways and backward walking. When compared to existing methods, the walking speed of iCub is increased by approximately 75% and the step period decreased by 45%. It was successfully tested with a reduced version of the iCub (HeiCub), but it was also shown to be applicable to the full iCub in simulation. The measured outcomes of the experiments are the walking velocity, the cost of transport, tracking precision of the Zero-Moment Point (ZMP), CoM and joint trajectories. The online feedback was shown to improve the walking stability by means of an improvement of the CoM tracking precision by 30% and the ZMP tracking precision by 60% compared to the same method without CoM position feedback control.


Fleet management has achieved great success benefiting from the application of deep reinforcement learning (DRL) in recent years and has yielded many successful commercial applications like ride-hailing services, whose basic goal is to efficiently manage the fleet of vehicles to meet the demand separated temporally and spatially. However, research that provides insight about how existing methods succeeded in dealing with massive agent interactions from a multi-agent perspective is still missing. In this paper, we review the RL methods of order dispatching and vehicle re-positioning in recent years, and classify them from the perspective of multi-agent reinforcement learning (MARL). We provide a comparison of vehicle-based methods, grid-based methods, and order-based methods, along with the popular datasets and open simulators. Afterward, we discuss several challenges and opportunities for the application of DRL in this domain.


In the city of Gdansk in Poland, in the very centre of the Baltic capital, on 17 June 2017, a new draw footbridge was ceremoniously opened to the public. The Ołowianka footbridge represents the long-time much-needed link between the highly tourist-visited historical old town and Ołowianka Island, where further cultural, tourist and recreation facilities are located. The bridge spans a very busy navigable channel of the Motława River, leading inward towards other city channels, a harbour for many tourist ships and the Gdansk Marina. Being the main navigable entrance to the city centre, the Motława is constantly under nautical traffic, so the Ołowianka footbridge operates 24/7, according to a 30-minute schedule. The Ołowianka footbridge is an extraordinary acquisition for the city of Gdansk, which immediately became a new landmark and much more in the already very picturesque historic city centre. Not just its design, but also its carefully chosen location and its realisation at the right moment, has made this bridge indispensable to the inhabitants, visitors and the administration of the city of Gdansk, decisively contributing to further development in the Ołowianka Island area and its surroundings.


the rural economy. Forman provides a very useful summary of existing data about landholding patterns and types of rural labor and cogently explores the "asymmetrical socioeconomic bonds that characterize Brazilian peasant society" (p. 75). Forman's imaginative analysis of the "sociology of the marketing system" (p. 90) in which he constructs a typology of marketplaces and relates these to marketing patterns in general is perhaps the most useful part of his book. His discussion of the "panaceas of development" (p. 115), the Brazilian government's programs to alleviate peasant poverty, is a useful, if pessimistic, overview of the various approaches taken in recent years by different governments. Unfortunately, his analysis of the rural political process provides mostly secondary information about politics and a review of available material about the masses. In his concluding chapter, the author synthesizes social protest movements and popular religion, phenomena long recognized and discussed as uncommon features of rural Brazil.

We examine the conditions for current-driven plasma instability in a double quantum wire system. The standard RPA formulation of longitudinal plasmon dispersion is employed to analyze the collective modes of this system in the presence of steady currents, which we consider to be equal and opposite in the two wires. We show that, for wires carrying equal steady currents in opposite directions, the quasi-ID plasma waves propagating along the wires become unstable when the electron drift velocity falls between the phase velocities of the acoustic and optical plasma modes of the Coulomb-coupled wires.


Beef tenderness and color stability were evaluated in conventional and modified atmosphere packaging (MAP) systems. Equal portions of inside rounds removed immediately (PMO) or at 4 8 h postmortem (PM48) were vacuum packaged (VP) whole or cut into steaks and packaged in 80%N2:20%C02 MAP. On day 12, MAP environments were exchanged for 80%O2:20%C02. Calpastatin activity was lower at 2 d postmortem for PM48 steaks than PMO steaks. Electrophoresis indicated more degradation of 50 and >250 kDA compounds at 2 d postmortem for PM48 than PMO steaks. Steaks from PM48 required less shear force than PMO steaks. HunterLab 'L', 'a' and ' b' values were higher for PM48 steaks versus PMO steaks. The lethality of ozone to Escherichia coli (E. coli) and Pseudomonas aeruginosa was investigated using four ozone concentrations (0, 100, 1000, 5000 ppm) and three exposure times (1, 10, 50 m i n ) . No differences were detected between 0, 100, or 1000 ppm ozone in log CFU on plates, 5000 ppm resulted lower log CFU. Exposure time had no effect. The experiment was repeated with ozone concentration levels of 0, 1000, 2500, and 5000 ppm. No difference was detected between 0 and 1000 ppm ozone for log CFU per petri dish. Concentrations of either 2500 or 5000 ppm significantly reduced E. coli and Pseudomonas counts.

I was 14 when I met the doctor who left me resolved never to see another GP for the rest of my days. Of course, eventually I not only saw GPs, but became one. I have never forgotten this fateful consultation, however, and I think that it shaped the way that I deal with that particularly difficult group, teenagers.

There were three of us children, aged 14, 11, and 8. We lived pretty rural lives and my mother knew what was what, so she was not particularly upset when we all had worms. However, in order to be treated, she was told by a dragon receptionist that we had to see the doctor. This was quite an event, as we had not seen a doctor since one had seen us with measles four years earlier.

Streaming time series retrieval (TSR) has been widely concerned in academia and industry. Considering the large volume, high dimensionality and continuous accumulation features of time series, there is limited capability to perform in-depth similarity searching directly on the raw time series data. Therefore, time series representation, which can provide the dimension reduction-based approximate results for the raw data, should be utilized in the first step for streaming TSR. However, the existing representation-based TSR methods mainly have two limitations: on the one hand, the representation efficiency of the current methods is too slow to adapt for real-time streaming time series representation; on the other hand, the retrieval efficiency of them is also not ideal, and thus fails to recognize the specific given sequence patterns on the streaming data effectively. In this paper, we present an efficient retrieval method on streaming time series. Concretely, our method can incrementally represent the features of streaming data to automatically prune the corresponding dissimilar sequences and retain the most similar candidates for efficient one-pass searching. Extensive experiments on real world datasets have been conducted to demonstrate the superiority of our method.


Automatic evaluation is an efficient alternative of capturing the sentiments and the attitude of a targeted audience towards a specific topic or subject. The starting context of our research is represented by the social media's important role in everybody's life. As the social media includes the web technologies that enable us to communicate directly and to modify user-generated content, the adoption of such online communication channels, as well as social networks (e.g., Facebook, Twitter, Google+) or Computer Supported Collaborative Learning (CSCL) technologies (e.g., chat, wiki, blog, forum) have gained an increasing trend and have reshaped interaction and information access. The purpose of this paper is to present an overview of opinion mining techniques, to describe the implementation of a previously developed system within our research group - Emotion Monitor -, alongside with our current improvements, such as the new trust module for evaluating the system's confidence in the current user, as well as enriching the user's profile in order to further personalize the generated results. In the end, the system predicts the manner in which a news article is affecting the emotional state of a user by integrating specific natural language processing techniques (especially Latent Semantic Analysis) and the reader's profile.

An RCA CCD has been used in a scanning mode on the Palomar 1.5-m telescope to obtain high precision photometric images of three early-type galaxies. Advantages of this mode of operation include much reduced pixel-to-pixel sensitivity variations and more accurate sky subtraction. Frames in B, V, R, and I of NGC 4486 (M87) have been used to show, by comparison with published high quality surface photometry and aperture photometry, that this instrument produces measurements accurate at the 0.02-mag level at surface brightnesses above that of the sky. These frames of M87 and similar images of NGC 2300 and NGC 2768 reveal several interesting features of color variations in the inner regions of these early-type galaxies. NGC 2768 is found to have a dust ring or disk perpendicular to its plane of symmetry. All the colors appear to become bluer gradually outward from the center, with M87 showing the strongest gradients. The shapes of the contours of constant color are rounder, at small radii (<20 arcsec), than the isophotes in NGC 2300 and NGC 2768. This is not predicted by any galaxy formation picture, but would seem to support dissipationless collapse or mergers as the dominant processes in the formation ofmore » early-type galaxies.« less

Since Phillippe Aries in his influential Centuries of Childhood (1962) sought to demonstrate that the concept of childhood was a relatively recent invention of Western society, an abundance of works on the changing cultural meanings of childhood have appeared. "The history of childhood has now become a major industry among scholars," writes Neil Postman in The Disappearance of Childhood (1). He adds, however, that historians usually come not to praise but to bury, and that when we turn a cultural value into an object of nostalgia and contemplation it is a sure sign of that value's obsolescence. Postman, a professor of Media Ecology at New York University, advances the bold proposition that childhood as it has been known since the late seventeenth century is rapidly vanishing and probably won't be resurrected without major changes in our communication system. He asserts that the concept of childhood as a distinct period of life requiring special kinds of supervision and care arose with the printing press, which erected a knowledge barrier between those who could read (adults) and those who couldn't (children). With the rise of literacy came schools and schooling and a further defining of childhood as a separate stage of life with its own internal requirements. Literate adult society meanwhile collected an ever-richer content of secrets to be kept from the young; secrets about social and sexual relations, about money, violence, illness, and death. Postman contends that so long as adults could withhold such information they could also maintain a separateness from (and control over) children. But if ever the knowledge gap were to disappear, so would childhood. This gap has been all but closed by the mass media, Postman believes. Television — the "total disclosure medium" —is the primary culprit because it does not discriminate between viewers but offers up


Methanol extract from Lippia graveolens (Mexican oregano) was studied in order to identify inhibitory bioactives for protein tyrosine phosphatase 1B (PTP1B). Known flavone as lutein (1), and another flavone glycoside such as lutein-7-o-glucoside (2), 6-hydroxy-lutein-7-ohexoside (3) and lutein-7-o-ramnoide (4) were isolated from methanol extract of aerial parts of the Lippia graveolens. All isolates were identified based on extensive spectroscopic data analysis, including UV, IR, NMR, MS and compared with spectroscopic data previously reported. These flavones were evaluated for PTP1B inhibitory activity. Among them, compounds 1 and 3 displayed potential inhibitory activity against PTP1B with IC50 values of 7.01 ± 1.25 μg/ml and 18.4 μg/ml, respectively. In addition, compound 2 and 4 showed moderate inhibitory activity with an IC50 value of 23.8 ± 6.21 and 67.8 ± 5.80 μg/ml respectively. Among the four compounds, luteolin was found to be the most potent PTP1B inhibitor compared to the positive control ursolic acid, with an IC50 value of 8.12 ± 1.06 μg/ml. These results indicate that flavonoids constituents contained in Lippia graveolens can be considered as a natural source for the treatment of type 2 diabetes.


We have synthesized the nano-europium rare-earth complex Eu(DPC)3,and determined its infrared spectrum,fluorescence spectrum,ultra-violet spectrum and elemental analysis.The results show that this compound has good optical characteristics,fluorescence nature and biological activity.Accordingly,it will be predicted with a spectral potential to be used as a fluorescence probe in environmental analysis and time-resolved fluoro-immunoassay (TRFIA) experiments.


This paper presents a summary of the first phase of a two-part research project supported by PATH and the State of California, to explore the potentials for Intelligent Transportation Systems as components of an evolving paradigm featuring the application of advanced network management techniques to Urban mobility problems. This first phase shows how operational network, or system management techniques have been proven highly successful when applied to critical resource problems in other arenas of public and economic infrastructure, and what this means for proponents of ITS. Specifically, this paper discusses related infrastructuresair traffic control and energy managementfor lessons in devising policies (and underlying technologies) to calibrate supply and demand, thereby enhancing system efficiency. The paper first considers the steps taken by FAA to accommodate rising air demand through their slot allocation and then considers federal legislative actions taken by US Congress to encourage a wider range of supply sources for the energy demand. The second phase, still in progress, will treat more specific deployment issues for ATMS/ATIS systems in California

The decision was difficult because the Editorial Advisory Board also expressed high appreciation of the articles coauthored by Castillo D.I., Queller D.C. and Strassmann J.E. "Cell condition, competition, and chimerism in the social amoeba Dictyostelium discoideum" and Baracchi D., Cusseau G., Pradella D. and Turillazzi S. "Defence reactions of Apis mellifera ligustica against attacks from the European hornet Vespa crabro".


THIS paper presents the results of study of the primary classification of organisms, the system of kingdoms, as continued beyond my previous discussion of the subject (1938). The present contribution was read and discussed at a meeting of the Western Society of Naturalists and again by a group called together by Dr. S. F. Light, of the University of California. The participants on these occasions showed a gratifying interest. I did not receive, and must not convey, the impression that the scheme here put forward was accepted. Cogent criticisms were offered. These are cordially appreciated, and have been applied in revision, in part, according to my own judgment and responsibility. The conventionally accepted distribution of organisms between two kingdoms, Plantae and Animalia, requires revision as a matter of intellectual consistency. It is gene erally acknowledged that the boundary between the two kingdoms is indefinite. Two considerable groups, the myxomycetes and the flagellates, are regularly claimed for' both kingdoms. As to the myxomycetes, this situation was produced by the studies of a distinguished botanist. De Bary (1858), having discovered the essential features of the life cycle of these organisms, expressed the opinion " dass die Myxomyceten nicht dem Pflanzenreiche angeh6ren, sondern dass sie Thiere, und zwar der Abtheilung der Rhizopoden angeh6rig, sind. " He emphasized this opinion by further publication in a zoological journal (1859). The resulting uncertainty is not a serious matter: the myxomycetes are believed to be a derived group whose position does not affect that of others. On the other hand, the position of the flagellates is recognized by most biologists who are concerned with the


We read with interest the article by Alnemri et al. aiming to compare the costs of Inhalation anesthesia (IA) and total intravenous anesthesia used in obstructive sleep apnea (OSA) surgery. We appreciate the authors' work because the monetary value of every minute wasted in the operating room ranges from $7 to $100. Therefore, preventing time wastage in the operating room increases the efficiency of surgeons and anesthesiologists, resulting in higher turnover and lower health care costs by performing more operations. However, we would like to contribute to this issue and present our criticisms of the authors' work. The anesthetic agents used with the IA definitions are not standardized. There are at least three combination options in IA (sevoflurane, desflurane, or isoflurane with remifentanil), which changes the surgery cost because of both their pharmacodynamic properties and price per box are different. In addition, it is understood that the depth of anesthesia is not standardized between groups. However, Bispectral index monitoring should be used to ensure the equal depth of anesthesia between groups in studies aiming at cost research among anesthetic agents. Additionally, the study would be more objective if the authors focused on surgeries performed by a single surgeon to reduce inter-surgeon variation. Because depending on the experience, surgical technique, and habits of the surgeon performing the surgery, the duration and total cost of the surgical procedure may vary. For example, it was shown that when the assistant surgeon performed the tonsillectomy surgery, the duration of the surgery was increased by 9.6 min compared to the senior surgeon. In addition, the effective regional block performed by the surgeon before the operation reduces the degree of surgical stimulus, affecting the required anesthetic agent concentration and cost calculation. On the other hand, complications in patients undergoing OSA surgery are both more challenging to manage and have a higher incidence. However, risks that may affect the cost other than postoperative nausea and vomiting, which are frequently present in OSA patients and cause delayed recovery in the postoperative period (i.e., pulmonary hypertension, desaturation, systemic hypertension, etc.), and interventions other than routine general anesthesia (i.e., difficult endotracheal intubation, difficult ventilation, etc.) have not been compared in the study. As a result, the cost calculation of any surgical procedure cannot be determined solely and simply by the price per box of anesthetics and consumables. It is also necessary to consider the complications that have arisen and the individual characteristics of the patient and the surgeon.


Metal working operations often result in MWFs mist.MWFs aerosols,especially that particle size less than 5 μm,are harmful to human health and associated with occupational diseases.MWFs mist control is attracted great interests in foreign countries many years ago,and compulsory standards have been published.During May and August,2003,a large survey of MWFs mist concentration in 43 plants in Jiangsu,Zhejiang and Shanghai by SINOPEC Shanghai Petrol-Products Application Institute shows that there are 39.5% of MWFs mist concentration less than 0.5 mg/m3,86% of them less than 5 mg/m3,but still 14% of them more than 5 mg/m3.Solutions to effectively reduce MWFs mist include using mechanical methods,choosing mist-suppressing MWFs and highly treated base oil.Corresponding statutes of occupational MWFs mist control levels and new types of MWFs are urgently suggested.

The effect of epitaxial strain on the cation distribution in spinel ferrites CoFe2O4 and NiFe2O4 is investigated by GGA+U total energy calculations. We obtain a very strong (moderate) tendency for cation inversion in NiFe2O4 (CoFe2O4), in agreement with experimental bulk studies. This preference for the inverse spinel structure is reduced by tensile epitaxial strain, which can lead to strong sensitivity of the cation distribution on specific growth conditions in thin films. Furthermore, we obtain significant energy differences between different cation arrangements with the same degree of inversion, providing further evidence for recently proposed short range B site order in NiFe2O4.


We apply a pseudospectral method to numerically study the dynamics of vortices found within a low viscosity non-Newtonian fluid with a Carreau fluid rheology. The application of a Carreau fluid rheology avoids the commonly observed complications in power-law models at zero strain-rate. We find that fluids with a shear thinning rheology will preserve the small scale features of the flow. In particular, for vortex-solid wall interactions, shear thinning fluids can exhibit behavior associated with Newtonian fluids at a much higher Reynolds number. This can include secondary vorticity generation, and multiple vortex-bottom collisions each marked by periods of higher bottom shear rates. Using a variety of experimentally determined parameters from the literature, we argue that these results have direct application to many non-Newtonian fluids, including non-Newtonian fluid mud layers found on lake and ocean bottoms.

People with beta-ureidopropionase deficiency can have low muscle tone (hypotonia), seizures, speech difficulties, developmental delay, intellectual disability, and autistic behaviors that affect communication and social interaction. Some people with this condition have an abnormally small head size (microcephaly); they may also have brain abnormalities that can be seen with medical imaging. Deterioration of the optic nerve, which carries visual information from the eyes to the brain, can lead to vision loss in this condition.

Two isolates of Meloidogyne incognita from separate field sites in central California were virulent to five cowpea (Vigna unguiculata) genotypes carrying resistance gene Rk and three other isolates were Rk avirulent in findings based on egg production in greenhouse experiments. Egg production and root galling at the two field sites with virulent populations and at one field site with an avirulent population confirmed the greenhouse results. The effects of nematodes on wilt disease caused by Fusarium oxysporum f. sp. tracheiphilum and on cowpea yield were examined over 3 years at the two sites infested with virulent nematodes. Main plots in the split-plot experiments were treated with a nematicide or were not treated. Cowpea genotypes planted in subplots had combined nematode (gene Rk) and wilt resistance (genotypes CB46, 7964, and 8517), nematode resistance only (CB5), wilt resistance only (CB3), or no resistance (8679). Infection by M. incognita did not predispose wilt-resistant genotypes to wilt disease on the basis of cumulative incidence of plants with visible symptoms or midseason and late-season vascular discoloration ratings. On wilt-susceptible genotypes, wilt disease occurred in nematicide-treated plots and was exacerbated by nematode infection in nontreated plots regardless of the presence of Rk. The yield of wilt-resistant genotypes was suppressed an average of 17% as a result of nematode infection in nontreated plots compared with plots treated effectively with a nematicide. Wilt-susceptible genotypes had significantly lower yield than wilt-resistant genotypes in treated plots, and in nontreated plots yield of wilt-susceptible genotypes was suppressed an average of 37 to 65% because of the combined effects of nematode and wilt infections.

With the development of the economy and society, security monitoring issues have received a lot of attention from industry and academia. Among them, invading pedestrian targets in low-light environments have the characteristics of high image noise, low contrast, and lack of color information. How to detect pedestrian targets in a low-light environment is a challenging problem in the current surveillance field. Aiming at the lack of texture and color information of monitoring images in low light environments, a pedestrian targets recognition algorithm in low light environments based on the fusion of visible light and infrared is proposed in this paper. First, use the defogging algorithm to enhance the brightness, clarity, and contrast of the visible light image, improve the signal-to-noise ratio of the image and restore the detailed features of pedestrian targets. Second, convert the RGB image to an HSV image to enhance the sensitivity of the algorithm to color. Then stitch the HSV image and the infrared image to form a four-channel HSV-G image. This paper uses infrared imaging's high sensitivity to light to improve the recognition rate of pedestrians in low light environments. Through experiments, the method proposed in this paper has achieved good results on a self-made low-light environments pedestrian target data set. The mAP reached 82%, FPS reached 67. The research results can provide an important basis for the recognition of pedestrian targets in low-light environments.

Purpose: Although volumetric CT (VCT) is widely used nowadays, its imaging performance is greatly hindered by the inferior image quality mainly owing to large x‐ray scatter signals, which lead to CT number inaccuracy and image contrast loss. Among existing algorithms, measurement‐based scatter correction methods efficiently obtain accurate scatter estimation without prior knowledge on the object. However, with a beam blocker in the field to attenuate primary, it is generally believed that the acquired data in scatter measurement projections are not complete for an accurate reconstruction. Thus an extra scan or moving the blocker during the scan is typically required. In this work, we propose a new measurement‐ based scatter correction algorithm without primary compensation. An accurate reconstruction is achieved with one single scan and a stationary x‐ ray beam blocker, two seemingly incompatible features. Methods: The blocked areas are distributed over the projection where primary signals are redundant using a new beam blocker with a "crossing finger" shape. Scatter is then accurately estimated by interpolation and scatter‐corrected CTimages are obtained using an FDK‐based reconstruction. Three blockers with different strip gaps are manufactured for optimal strip gap selection. Results: The proposed method is evaluated using two phantom studies on our tabletop CBCT system. On the Catphan©600 phantom, our approach reduces the reconstruction error from 207 to 9 Hounsfield unit (HU) in the selected ROI, and improves the image contrast by a factor of 2 in the high‐ contrast regions. On an anthropomorphic head phantom, the reconstruction error is reduced from 154 to 3 HU in the soft‐tissue region. A blocker with a strip gap of 20mm achieves optimal image quality. Conclusions: Our method inherits the main advantages of measurement‐based methods while avoiding their shortcomings. It has the potential to become a practical scatter correction solution widely implementable on different VCT systems.


Temporal information retrieval is widely used to organize the data according to the time considerations. Social media has rapidly changing time varying content. Temporal information retrieval has made it easy to explore this kind of dynamically changing content. Clustering involves grouping the data in such a way that their inter cluster similarity is low and intra cluster similarity is high. Similar set of data belongs to a single cluster making analysis of data easier. In this work, relevant features are extracted from the Social Media platform 'Facebook'. These features form the basis for ranking and clustering of users. Proposed ranking technique involves the temporal dimension of data and comments by different users. Data mining toolkit WEKA is used for clustering. Three algorithms used for clustering are: XMeans, Expectation Maximization and Hierarchical. Comparison of results for these algorithms shows that XMeans and Expectation Maximization are better for Social Media based Temporal data rather than hierarchical clustering algorithm.


Dendrimers represent a relatively new class of highly branched polymers (Tomalia 1995) that have found several pharmaceutical applications such as enhancement of the solubility of poorly soluble drugs and the efficient delivery of DNA and oligonucleotides (D'Emanuele et al 2003). Surface engineering has been found to reduce cytotoxicity and enhance the rate of transport of dendrimers across epithelial cells (Jevprasesphant et al 2003). The objectives of this study were to investigate the transport mechanisms of PAMAM dendrimers and surface-modified dendrimer conjugates across Caco-2 cell monolayers, and also the use of dendrimer–drug conjugates to enhance the solubility of poorly soluble drugs and bypass the P-glycoprotein (P-gp) efflux transporter. Dendrimer (G3 PAMAM) and lauroyl-dendrimer conjugates were chemically bound to propranolol base, a model P-gp substrate and low solubility drug, using chloroacyl chloride as a linker. Conjugates were designated G3Px and G3LzPx, where 3 represents the dendrimer generation, z the number of attached lauroyl chains and x represents the number of attached propranolol molecules. Characterisation of conjugates was by HPLC, FT-IR,HNMR and CNMR. The apparent permeability coefficients (Papp) of propranolol, propranolol–dendrimer and propranolol–lauroyl-dendrimer conjugates through Caco-2 cell monolayers were measured in both the apical (A)-tobasolateral (B) and B!A directions at 37 C in the presence and absence of the endocytosis inhibitor, colchicine (Col) (10 M), and at 4 C and propranolol quantified by HPLC. The effect of a P-gp inhibitor, cyclosporin A (CsA) (10 M), on the transport of propranolol conjugates was investigated in a similar manner. The effect of dendrimers and conjugates on monolayer integrity was determined from transepithelial electrical resistance (TEER). Highresolution imaging techniques (flow cytometry, confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM)) were used to determine the transport mechanism. A significant enhancement of A!B and decrease in B!A Papp of propranolol was observed when propranolol was covalently bound to G3 dendrimer. For example, the A!B Papp of G3P2 was approximately 3.6 times greater than that of unconjugated propranolol, while no enhancement was observed in simple mixtures of propranolol and G3 dendrimer. A more pronounced increase of A!B transport of propranolol was observed when propranolol was conjugated to G3L6 carriers (14.4 fold increase for G3L6P2). The results suggest that dendrimer carriers bypass the P-gp efflux transporter. The A!B transport of dendrimer and dendrimer– propranolol conjugates was significantly decreased in the presence of Col and at 4 C, suggesting that the mechanism by which dendrimers enhance transport involves endocytosis. No difference in the permeability of propranolol–dendrimer conjugates was found in the presence and absence of CsA, indicating that the conjugates are not P-gp substrates. Flow cytometry, CLSM and TEM studies confirmed a significant level of dendrimer cellular internalisation in Caco-2 cells. The enhancement of propranolol transport by conjugation with dendrimers is due to the bypassing of the P-gp efflux transporter. The mechanism of transepithelial transport, for both dendrimers and conjugates is primarily via an endocytotic transcellular pathway.

It is one of the most serious obstacles to the industry in many industries that adopt contemporary technologies to manage continuous development and faster than ordinary jobs. Many of the scientists and researchers recommend using AI tools and digital technologies for industries. Machine language and artificial intelligence are used by many organizations in the human resources unit, where it undertakes an integrated task in recruiting, performance analysis, personnel selection, data collection for employees, providing real-time information and obtaining the right information. Artificial intelligence-based Human Resources (HR) applications have a solid potential to increase employee productivity and support HR experts to become knowledge and trained consultants that increase the success of the employee. HR applications authorized by artificial intelligence have the ability to analyze, predict, diagnose and seek and find more robust and capable resources.


To design low energy return trajectory for unmanned lunar probe, the dynamic model of the probe is developed under the elliptical four body problem in consideration of the effect of sun′s gravitation and lunar elliptical motion to the probe′s orbit. The existence and the dynamical characteristics of the return trajectory are analyzed. To deal with the strong nonlinearities of the dynamic model and the local convergence in the optimal process, an adaptive genetic algorithm is proposed which can adjust the self?evolution parameters according to the fitness of the population to improve the effectiveness of the evolution of the population to the global optimal point as well as to reduce the computation burden. According to the simulation results, the algorithm works well in optimizing the energy needed for the lunar probe to return to Earth, which is only 75% of that in the traditional hyperbolic matching method.


This paper provides an analytical comparison of seven current conceptions of alcoholism. Six dimensions are used for the purposes of comparison: (1) definition of alcoholism; (2) etiology; (3) alcoholic personality; (4) epidemiology; (5) treatment; and, (6) prognosis. In addition to the traditional conceptions of alcoholism such as A.A. and family therapy, the paper examines three more recent points of view—namely, the behavioral, the sociological, and the transactional conceptions. Throughout the analysis, areas of disagreement are highlighted and important issues arising from these disagreements underscored.

LaMnO3 (LMO) nanocrystals were synthesized at various annealing temperatures using MCM‐41 mesoporous silica. In this study, X‐ray diffraction (XRD) measurements and magnetic property measurements were performed. XRD results showed that LMO nanocrystals of ∼90 A in diameter are formed. These samples show ferromagnetic behavior below 280 K, which is nearly twice that of the critical temperature of bulk LMO crystal. The magnitude of the ferromagnetic moments is correlated with the intensity of the Bragg peaks of LMO nanocrystals. The high TC of the LMO nanocrystals might be caused by hole doping due to excess oxygen or cationic nonstoichiometry.


This workshop will be a tutorial on effective media production for computer science courses. We'll spend time breaking down the ways that you can use media in your courses, both live and pre-recorded. Good media production relies heavily on both well-planned curriculum and pre-production. As part of this, we'll focus on our work building courses around short 5-10 minute videos, which have been shown to encourage engagement from students. We'll discuss designing your content and process for efficient turn around, so that you can successfully build a course 'just in time'. The goal of the workshop is to share with participants the techniques we use in our own courses. We'll demo our workflows and favorite tools, with pointers on where to learn more. Along the way, we'll share how you can accomplish a well-produced video with minimal budgets, and where you can get the most out of adding hardware and software to your setup. This workshop will be highly interactive. For each topic, we'll start off with live demonstrations, but then spend time with hands-on questions from participants. Participants are encouraged to bring their questions and challenges to the workshop.
