Purpose: Uncompensated scattered radiation is one of the major image quality deteriorating factors in flat detector cone‐beam CT. Purpose of this work is to develop a fast, practical, and accurate method for a posteriori correction of X‐ray scatter. Method and Materials: Scatter estimation and correction is carried out using a novel approach based on locally approximating the imaged object by water sphere models. In each projection, the scatter contribution of each ray from the source to the individual detector pixels is derived from a pre‐calculated database of pencil‐beam Monte‐Carlo simulations. The different sphere configurations have the advantage over related existing methods that they allow to accurately reproduce scatter contributions of individual rays regardless of the position of object penetration. Systematic evaluation was carried out by constructing an extensive database of Monte‐Carlo patient simulations, by performing scatter measurements of 15 phantoms on a bench‐top X‐ray system, and based on rotational C‐arm acquisitions from clinical interventional procedures. Results: The novel method was found to produce far superior results than related state‐of‐the‐art approaches. Based on simulated projections of 13 CTdata sets of different body regions (head, thorax, abdomen, liver, pelvis), an average reduction of scatter‐caused inhomogeneities from 117 HU to 11 HU per‐voxel deviation from the ground truth was achieved. For individual data sets, the average level of the estimated scatter deviated from the respective optimum by only 5% as compared to a minimum of 14% for tested state‐of‐the‐art approaches. Experimental evaluation and application to clinical data confirmed robustness and efficient reduction of cupping and streak artifacts in reconstructed images. Conclusion: A practical software‐based method was developed allowing to accurately estimate scatter contributions in X‐ray projections. Utilization of this method efficiently reduces scatter‐caused artifacts, and thus substantially improves image quality in flat detector cone‐beam CT.


This paper discusses the particular steps that take place in the integration of a CD-ROM player to a computer. The computer can treat the CD-ROM player like any other external data storage device, however, a CD-ROM has a low data transfer rate as well as a low access time. The minimum data transfer rate for a CD-ROM player to a host computer is 176Kb/sec as compared with 625Kb/sec for a hard disk. Access time to the information is around one second compared to 0.15 second for the hard disk. To improve performance special software or hardware is needed. One way to compensate for the slow data transfer rate is to use a Small Computer Systems Interface (SCSI). Most of the SCSI configurations are single-initiator, single-targetsystems, with the CPU being the initiator and the CD-ROM player the target. The SCSI bus allows quick transfers of information and commands to I/O devices via a standard command protocol. This protocol sends command-description messages to target processors that process the commands. To improve the operation, the CD-ROM drive needs to provide an interim storage space for the data between the disc and the CPU. A single-ported cache buffer can provide this capability. RAM buffers are placed in the SCSI controller to allow faster data collection. Using DMA the transfer rate between devices is increased. The current CD-I standard calls for 2 DMA channels in the microprocessor. This eliminates disc to CPU transfer time by loading the process directly into DMA.


A sensitive and simple spectrophotometric method was developed for the determination of Chromium(VI) with Isonitriso p-isopropyl Acetophenone Phenyl Hydrazone. Chromium was complexed with Isonitriso p-isopropyl Acetophenone Phenyl Hydrazone and the reddish yellow colour complex was extracted into methyl isobutyl ketone. The absorbance of the complex was maximum at 443 nm. The molar absorptivity of the complex was 2.78 x 103lit.mol−1 cm −1 and Sandell's sensitivitywas 2.67 x 10−2 μg/cm2. The system obeyed Beer's law over the concentration range of 0.5 to 20 ppm. The composition of the complex (metal: ligand) was 1:6. This method was employed for the determination of chromium in Goa Beans and Soya Leaves Sample


OBJECTIVE
The aim of this study was to assess adherence in people on hemodialysis and determine the factors of poor adherence.

MATERIAL AND METHODS
This cross-sectional study took place throughout the month of September, 2012, in the hemodialysis center of the Sylvanus Olympio University Hospital, the only such center in Togo.

RESULTS
The study included 65 patients, with a mean age of 49.5 years (range: 22 to 77 years), more often men (sex ratio: 1.82) and married (74 %). More than half (58%) had completed secondary education, while 73% belonged to the least advantaged socioeconomic class; 61 (94%) had health insurance, and 57% had been on dialysis for 1 to 4 years. The compliance rate was 11%. The main factors associated with good adherence were marital status (p = 0.0339) and the patient's general health status (p = 0.001). Treatment fatigue (p = 0.0347), forgetfulness (p = 0.0001), dosage forms and drug characteristics (p = 0.0198) were all factors of noncompliance. Therapeutic non-compliance was proportional to the number of drugs prescribed (p = 0.4263).

CONCLUSION
Adherence in hemodialysis patients in Togo is very poor.


Essential oils from
 Monarda fistulosa
 L.,
 Satureja pilosa
 Vel.,
 Origanum vulgare
 subsp.
 hirtum
 Ietswaart. (Greek oregano),
 Micromeria dalmatica
 Benth.,
 Thymus longedentatus
 (Degen & Urum.) Ronniger, and
 Artemisa campestris
 L. were evaluated as inhibitors of seed germination in target plants
 Lolium perenne
 L. and
 Trifolium pratense
 L. using in vitro assays. The essential oils were applied on the seeds as aqueous solutions at concentrations ranging from 0.5–3.0 µL/mL. Complete inhibition was established at a concentration of 1.5 µL/mL with the most effective essential oils. Oregano oil was evaluated for its inhibitory activity on seed germination under field conditions; the essential oil was applied as an aqueous solution at concentrations of 3, 5, and 10 µL/mL on superabsorbent Terawet. The mass obtained was mixed with the seeds of the target plants and planted in a field. After 1 month, the results were evaluated based on the weight of the aerial parts of the plants from control and experimental areas. At the highest concentration studied, the weight of the plants was 77% lower in the experimental areas than in the controls. The chemical composition of the essential oils was analyzed using gas chromatography–mass spectrometry. The results showed that carvacrol-rich essential oils had a strong inhibitory effect on seed germination. The inclusion of the essential oil on a superabsorbent was a good way to preserve its herbicidal activity under field conditions as this prevented its rapid evaporation.


The optimal location of supports for the reduction of vibration in piping systems is an interesting structural problem, that can be approached also with the methods used in the updating parameters problems, especially when the cause of the vibration is due to a resonance or a ineffective damping level, and the shift of a critical frequency is an effective remedy. In the proposed paper a frequency domain method of Finite Element model updating is used in order to properly locate the natural frequencies of a given piping system, starting from the nominal condition. The method considers modal parameters, and enables to directly update the physical quantities of the finite element model, i.e., in the considered application, the stiffness and damping of the supporting devices. The model of the structure is made up by beam finite elements, lumped springs and masses, and rigid links. The general procedure is applied here updating the stiffness and location of the supports of the piping according to the comparison among the current frequencies of the piping systems structure and the ones that are required, according to specific requirements. Application to a system similar to a portion of an actual AP1000 (a new Advanced Passive Nuclear Reactor) piping-support layout is presented.

The causalities between the coronavirus disease 2019 (COVID‐19) and the risk of rheumatic diseases remain unclear. The purpose of this study was to investigate the causal effect of COVID‐19 on rheumatic disease occurrence.


Inter-annual to decadal sea-level variations from tide gauge records in the coastal zones of the Norwegian and Siberian Seas are examined for the period 1950–2010 using a combination of hydrographic observations, wind data, and theory. We identify two large areas of highly coherent sea-level variability: one that includes the Norwegian, Barents, and Kara Seas, and another one that includes the Laptev, East Siberian, and Chukchi Seas. We provide evidence of a new contribution to the sea-level variability along the Norwegian coast associated with the poleward propagation of sea-level fluctuations along the eastern boundary of the North Atlantic. When this propagating signal is combined with the local wind, we are able to explain over 70% of the variance along the Norwegian coast. The steric component explains ~61% of the sea-level (corrected for the inverse barometer) variability along the Norwegian coast. The high coherency between the sea level along the Norwegian coast and that in the Barents and Kara Seas suggests that part of the Norwegian signal propagates further north into these regions. We introduce an atmospheric vorticity index that explains much of the sea-level variability in the Laptev, East Siberian, and Chukchi Seas with correlations ranging from 0.73 to 0.81. In the East Siberian Sea, we identify a sea-level increase of ~22?cm between 2000 and 2003, which is partly explained by the vorticity index, and a decline of ~15?cm after 2003, which we relate to the strengthening of the Beaufort Gyre.


Traditionally, the teaching and learning of algebra has been addressed at the beginning of secondary education with a methodological approach that broke traumatically into a mathematical universe until now represented by numbers, with bad consequences. It is important, then, to find methodological alternatives that allow the parallel development of arithmetical and algebraic thinking from the first years of learning. This article begins with a review of a series of theoretical foundations that support a methodological proposal based on the use of specific manipulative materials that foster a deep knowledge of the decimal number system, while verbalizing and representing quantitative situations that underline numerical relationships and properties and patterns of numbers. Developing and illustrating this approach is the main purpose of this paper. The proposal has been implemented in a group of 25 pupils in the first year of primary school. Some observed milestones are presented and analyzed. In the light of the results, this well-planned early intervention contains key elements to initiate algebraic thinking through the development of number sense, naturally enhancing the translation of purely arithmetical situations into the symbolic language characteristic of algebraic thinking.

Psychopsidae (silky winged lacewings) are a small family of Neuroptera characterized by broad hirsute wings that impart a physical resemblance to moths. The fossil record includes many psychopsid‐like taxa from the Late Triassic to Early Oligocene from all major continents. Extant species have a disjunct, tripartite distribution comprising Afrotropical, Southeast Asian and Australian regions that is significant to historical biogeography. Two subfamilies are currently recognized: Zygophlebiinae in the Afrotropics, and Psychopsinae in Australia and Southeast Asia. This study explores phylogeny and historical biogeography of Psychopsidae, using data from biogeography, comparative morphology and molecular sequences (16S, 18S, CAD, COI). Our results show that: (i) the morphological phylogeny is incongruent with molecular data; (ii) Afrotropical Silveira Navás represent a separate lineage that warrants placement in its own subfamily; (iii) the family originated in Pangea; and (iv) the present genus level distribution resulted from two vicariance events associated with Gondwanan fragmentation.

BACKGROUND
Circular RNA (circRNA) has been shown to play an essential role in cancer progression, including nephroblastoma. Hsa_circ_0093741 was discovered to be highly expressed in nephroblastoma. However, its function and mechanism in nephroblastoma development are still vague.

METHODS
The expression levels of hsa_circ_0093741, miR-562 and FRS2 (Fibroblast Growth Factor Receptor Substrate 2) were detected using western blotting and quantitative real-time polymerase chain reaction. Functional experiments were performed by using cell counting kit-8, colony formation, 5-ethynyl-2'-deoxyuridine (EdU), transwell, scratch assays in vitro and animal experiments in vivo. The interaction analysis was conducted using dual-luciferase reporter assay and RIP assay.

RESULTS
Hsa_circ_0093741 was highly expressed in nephroblastoma tissues and cells. Functionally, hsa_circ_0093741 silencing significantly suppressed the growth, invasion, and migration of nephroblastoma cells in vitro. MiR-562 was decreased in nephroblastoma, and was validated to be a target of hsa_circ_0093741. Inhibition of miR-562 reversed the anticancer functions of hsa_circ_0093741 silencing on nephroblastoma cells. FRS2 expression was increased in nephroblastoma and served as a target of miR-562, moreover, FRS2 overexpression attenuated the inhibitory functions of miR-562 on the nephroblastoma cell malignant phenotypes mentioned above. Pre-clinically, lentivirus-mediated hsa_circ_0093741 silencing also impeded nephroblastoma tumor growth and metastasis in vivo.

CONCLUSION
Knockdown of hsa_circ_0093741 suppresses nephroblastoma cell growth, migration and invasion by regulating the miR-562/FRS2 axis, suggesting the potential involvement of hsa_circ_0093741 in nephroblastoma progression.

In the transition‐depletion region of both P+N and N+P step silicon junctions, gold impurity is in the negatively charged acceptor state. It decreases the net charge in the transition region of the P+N case and increases the net charge in the transition region of the N+P case. This results in a corresponding increase and decrease respectively of the breakdown voltage of these cases. Experimental data obtained show very good correlation with this model.


Background/Aim: Formation of stoma during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal carcinomatosis (PC) is often performed to reduce the risk of anastomotic leak. Subsequent stoma reversal provides a unique opportunity for second-look surgery to detect early peritoneal recurrence. Current surveillance methods often fail to detect disease early, including imaging and biochemical markers. In our study, we examined the safety and efficacy of second-look surgery for detection and treatment of disease recurrence. Patients and Methods: We performed a retrospective analysis of prospectively collected data from 35 patients undergoing stoma reversal from 2015 to 2019 with negative pre-operative imaging. Results: A total of 37% of cases had disease recurrence, with a median peritoneal cancer index of 4. Complete cytoreduction was achieved in all patients. The majority of patients (77%) suffered minor complications only. Median length of hospital stay was 12 days. Conclusion: Second-look surgery detects early disease recurrence and is a safe alternative to conventional screening methods post primary CRS/HIPEC for PC. Long-term, routine second-look surgery can improve survival.

The adhesion of lymphocytes to cytokine‐treated high endothelium was studied using cultured high endothelial cells (HEC). Pretreatment of the HEC layer with a variety of cytokines caused up‐regulation of lymphocyte adhesion with the effects ordered interferon γ (IFN‐γ) > tumor necrosis factor‐α (TNF‐α) ⩾ interleukin 1β (IL 1β). Increased lymphocyte adhesion was found to be independent of ICAM‐1 as expression by HEC was not increased by cytokines and antibodies against ICAM‐1 did not block adhesion. The peptide CS1 and anti‐β1 integrin subunit antibodies, however, caused partial inhibition of lymphocyte adhesion thus indicating a role for fibronectin on HEC and α1β1 on lymphocytes. Study of the kinetics of lymphocyte adhesion showed that the effects of IFN‐γ and TNF‐α were persistent and remained detectable 2.5 h after removal of the cytokines whereas the effects of IL 1β were transient and were not sustained beyond 1 h. All of the cytokines used caused transient increases in the number of surface‐bound lymphocytes with IFN‐γ > TNF‐α ⩾ IL 1β, however, the most dramatic effect was on the transmigration of lymphocytes across the HEC. Both IFN‐γ and TNF‐α caused sustained increased transmigration with IFN‐γ having the greater effect. IL 1β had little effect on transmigration. This model demonstrates that the binding and transmigration of lymphocytes across HEC can be differentially regulated by the actions of individual cytokines. These results support the concept that locally produced cytokines regulate HEC function within the lymph node.


Nucleic acids extraction is the initial stage of molecular genetic research. The effectiveness of using a certain method of DNA extraction is determined by the amount of extracted DNA, the degree of probe degradation, the time consuming and laboriousness of the procedure. When researching rare, endangered species and populations, special attention is paid to extracting DNA from sources that do not cause destruction or death of individual. The current study was aimed at comparison the effectiveness of the most common methods of genomic DNA isolation from fish tissues for further use in the polymerase chain reaction. Essentially three DNA extraction methods were employed and compared for the quality of isolated DNA ‒ the phenol-chloroform extraction method, the salt extraction method, and the sodium perchlorate extraction method. Samples of fins, liver and caver taken from sterlet individuals fixed in ethanol served as material for research. The study of the effect of DNA probe quality on PCR course was carried out using two types of PCR ‒ site-specific, amplifying the fragment of cytochrome-b gene, and multilocus ‒ ISSR-PCR with a trinucleotide primer (AGC)6T. A comparison of DNA extraction methods confirmed that all of them enable obtaining high-quality DNA from both fresh and archival fish tissue samples for site-specific amplification. The yield of nucleic acids using different fish tissues (fins, liver and caver) is not the same. Therefore, when it is necessary to obtain the maximum amount of DNA, it is advisable to use the salt extraction method. In case of ISSR-PCR, different degrees of DNA purification affected the course of amplification. Additional purification by the method of sorption on Silica allows removing possible PCR inhibitors and obtaining clear spectra of electrophoretic separation of amplification products, regardless of primary DNA quality.
Key words: DNA extraction methods, sterlet tissues, site-specific PCR, multilocus PCR.


Abstract This study investigated the effect of first language (L1) transfer in the recognition of second language (L2) collocations and unacceptable word combinations across low-intermediate to advanced learners of English, and the relationship between proficiency and the recognition of L2 collocations. The study targeted learners from two different L1 backgrounds and native speakers of English in order to disentangle the effect of L1 transfer from the effect of intralingual factors. Four types of English verb-noun combinations were included: English-Korean-Mandarin, English-only, Korean-only, and Mandarin-only phrases. A phrase acceptability judgment task and a phrase recognition report were used. The performances of 92 participants were analyzed using mixed effects modeling. The results from both Korean and Mandarin groups revealed no L1 influence in the recognition of unacceptable L2 word combinations, even at low levels of proficiency. The results also showed that L2 proficiency predicts learners' ability to rule out grammatical-but-unacceptable L2 word combinations, but not the ability to recognize L2 collocations

Global climate change and COVID-19 have changed our social and business life. People spend most of their daily lives indoors. Low-cost devices can monitor indoor air quality (IAQ) and reduce health problems caused by air pollutants. This study proposes a real-time and low-cost air quality monitoring system for smart homes based on Internet of Things (IoT). The developed IoT-based monitoring system is portable and provides users with real-time data transfer about IAQ. During the COVID-19 period, air quality data were collected from the kitchen, bedroom and balcony of their home, where a family of 5 spend most of their time. As a result of the analyzes, it has been determined that indoor particulate matter is mainly caused by outdoor infiltration and cooking emissions, and the CO2 value can rise well above the permissible health limits in case of insufficient ventilation due to night sleep activity. The obtained results show that the developed measuring devices may be suitable for measurement-based indoor air quality management. In addition, the proposed low-cost measurement system compared to existing systems; It has advantages such as modularity, scalability, low cost, portability, easy installation and open-source technologies.


This paper reports the design and simulation of an integrated CMOS threshold voltage dependent thermal sensor with a 10-bit frequency-to-data converter to generate the required temperature binary code. The thermal sensor makes use of the dedicated MOS transistors on CMOS process to build two ring oscillator structures, one is PMOS-enabled while the other is NMOS-enabled. The NMOS-enabled suffers a threshold voltage drop while passing the power supply rail. This leads to a lower oscillation frequency of the NMOS-enabled ring oscillator compared to that of PMOS-enabled ring oscillator. The division of the two oscillation frequencies is found to be a good inversely fit of temperature. The linearity error is confined to +/-3°C over a temperature range of -40°C to 130°C and supply voltage of 5V ± 5%, with calibration performed over three temperature ranges, i.e. -40 to 25°C, 26 - 98°C, and 99 - 130°C.


In this paper, we propose and analyze ultra wide band (UWB) systems employing binary ZCD (zero correlation duration) code for wireless body area network (WBAN). When there are several wireless communication devices on a human body, multiple access interference (MAI) can occur. Hence, in order to reject MAI and enhance overall system performance, binary ZCD code is utilized as spreading code for UWB system. The performance is evaluated in terms of bit error rate (BER). From simulation results, it is confirmed that the UWB system with the ZCD code achieves better performance compared with that of pseudonoise (PN) code. The results of the paper can be applied to design and implementation of UWB systems for WBAN applications.


Music is a global phenomenon but each musical system is simultaneously a model of, and a model for, the cultural system of which it is a part. If musical systems are so embedded in cultural difference, so too are other phenomena we consider "normal", "natural" and the "the way things are". Gender is not the only category that shapes and or determines one's musical or artistic and/or individual experience; class, age, ethnicity are also significant and interdependent factors. The universe in which women have existed as musicians and creative artists is far from natural. In fact the musical world and cultural sector, as a whole, is not only constructed from a male perspective, but also simultaneously constituted as a means of perpetuating male cultural hegemony and social control. Until very recently – in almost all forms of musical culture – women could not explore alternative modes of expression even if they wished to since they had to compete with men. Despite having more limited access to musical education, fewer opportunities for publication and


We introduce the notions of regular and purely irregular charges with respect to a pair of pavings and study their structural properties. Moreover, we link regularity and σ-additivity, obtaining some generalizations of well-known theorems. Finally, when the pavings satisfy some reasonable weak conditions, we can decompose any bounded charge into regular and purely irregular decomposants; this decomposition becomes the Hewitt-Yosida one, whenever the charges are defined on the Baire σ-field of a countably compact space


The obvious importance of blood coagulation in hemostasis justifies the fact that it has probably been more widely and thoroughly investigated over a span of two hundred years than any other biolog ical system. The evidence that all but one of the factors involved in forming a blood clot actually exists is mainly clinical and genetic in that for each factor, a corresponding hereditary coagulation dis order has been described in man. Until the midcentury, interest in the field was limited to relatively few people who were actually engaged in its invest igation, although the volume of work on the subject was enormous. Morawitz in 1905 [1] took account of facts known at that time and put forth the "clas sical theory" of blood coagulation. Research in 1935 led to the discovery of vitamin K [2] and to the de velopment of the one-stage prothrombin time test [3]. The next decade produced the two-stage method for measuring prothrombin [4] and the iso lation of the anticoagulant drug dicumarol [5]. However, it has been only during the past twenty years that scientists from widely varied disciplines have unraveled the specifics of the molecular events leading to the formation of a blood clot. The result ing growth in knowledge has been explosive. Valu able documentations on the early advances in the knowledge of blood coagulation and detailed re views of the most recent discoveries can be found in the literature [6-11]. As a result, facts pertaining to the role of 14 trace plasma proteins, to a tissue pro tein factor, to membrane surfaces, Ca , and plate lets in the ultimate formation of a blood clot have become available. Apparent in most reviews, but rarely empha sized, is the fact that investigators use biochemical, biologic, immunologic and animal model technic as well as equipment of limitless complexity. Coagula tion lends itself to being recorded by viscometric, photometric, nephelometric and potentiometric methods complete, of course, with the latest me chanical and electronic developments. Successful undertaking of coagulation research obviously not only relies on the skill of the investigators but also is heavily dependent on research tools. In some in stances, as in endocrinology, a single experimental tool, namely the utilization of antibodies, has proven to be instrumental in the advancement and sophistication of knowledge in the entire field. In vestigators have capitalized on the specificity of antibodies to identify and label hormones and ste roid receptors in cells and to separate them from mixtures [12,13]. Perhaps appreciation of the im pact of individual experimental approaches on the promotion of knowledge in the field of blood coag ulation could lead to further important develop ments. This work is devoted to antibody technics used as tools in coagulation research and is written with two objectives in mind: (1) to identify areas where From the Department of Medicine and Pathology, College of Human Medicine, Michigan State University, East Lansing, ML


Rapidly emerging batteryless sensors are creating tremendous opportunities for truly wearable sensors for activity recognition. However, data streams from such sensors are characterized by sparsity and noise, which make activity recognition a challenging task. In this paper, we study the feasibility of passive computational RFID sensors for ambulatory monitoring. In particular, we focus on recognizing transfers out of beds or chairs and walking. Ideally, all these activities need to be monitored by movement sensor alarm systems to alert caregivers to provide supervision during the ambulation of older people in hospitals and nursing homes to prevent a fall. Our novel approach to partition continuous sensor data on natural activity boundaries and to identify transfers out of beds or chairs and walking as transitions between sequences of movements overcomes issues posed by the sparsity and the noise. We demonstrate through in-depth experiments the high performance (F-score > 93%) and the responsiveness of our approach.


ABSTRACT This mixed methods research project with 16 participants focused on the spiritual and emotional needs of 8–16 year olds who had a sibling with a chronic rare disease was undertaken by the Centre for Paediatric Spiritual Care at Birmingham Children's Hospital. Three research tools were included: Kidscreen 52 Health-related quality of life questionnaire with proxy version, 1–1 semi-structured interviews and focus groups. The data was viewed through the lens of Maslow's Hierarchy of Needs and Nye's interpretation of them. Key findings showed that having a sick child impacted the well child in all the areas of Maslow's hierarchy but particularly esteem and self-actualisation needs. Early interventions are recommended to support the well sibling to seek to ameliorate the impact on spiritual and emotional needs of having a chronically sick sibling. Advocacy and awareness raising is beneficial.


Flair and Loathing on the Front Page, by Jim Tucker. New Plymouth, NZ: Jim Tucker Media. 2022, 283 pages.
'NAMES make news' is a mantra drummed into the head of every young reporter and heaven help those who can't identify a vital quote or face. It is a lesson that veteran journalist and educator Jim Tucker never forgot. The evidence of that lies in the pages of Flair and Loathing on the Front Page, the first part of his memoir spanning a career that began in Taranaki in 1965 and which has gone full circle. Tucker is a regular columnist on the Taranaki Daily News after serving as a metropolitan newspaper reporter and editor then becoming one of New Zealand's foremost journalism trainers.


A discrete Pd6L4 Td-symmetric molecular cage and a discrete Pd4L4 square assembly were obtained using a coordination-driven self-assembly technique. The assembly, Pd6L4, was prepared via a face-directed method, utilising a 'cis-clipped' palladium(II) species and a new C3 symmetric tripodal hydrazinic ligand. The Pd4L4 square assembly was prepared via an edge directed method, using the 'cis-clipped'-palladium(II) species and a new C2 symmetric dipodal hydrazinic ligand. Both assemblies were characterised using multinuclear NMR and ESI-MS spectroscopic techniques and elemental analysis. The size of the assemblies were assigned from HR-TEM measurements, while DOSY NMR analysis established the presence of single component species in solution. Optimised structures obtained using Hartree–Fock calculations are in conformity with the experimental results. Both the assemblies show significant catalytic activity as heterogeneous catalysts for Suzuki–Miyaura coupling reactions under mild, aerobic and phosphine free conditions in aqueous ethanolic medium.

The casual organism was identified as Psuedocercosporachloroxyliae and MycovellosiellaadinaeFirdousi respectively
which were identified with the help of literature and confirmed by the experts. This is first report from Seoni and Madhya Pradesh.


A computational method of the formal linearization for nonlinear systems is proposed by using a piecewise cubic Hermite interpolation. We introduce a linearizing function that consists of the state variables, their squares, and the cubes. The nonlinear terms are approximated by the cubic Hermite interpolation and thus a formal linear system with respect to the linearizing function is acquired. This method is easily carried out with the aid of computers. A nonlinear filter is synthesized as an application of the method and is verified through numerical examples.


Monitoring of trace elements in soil provides efficient way to assess the qualitative and quantitative differences in element concentrations at different sites within a region. The aim of the study was to assess levels of trace elements regarding accumulation of the metals, as well as investigate whether of the soil factors (chemical and physical) which influence trace element concentrations in soil. The physico-chemical parameters (viz. pH, EC, MC, OC, and textural class) and trace elements concentrations i.e Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb and Zn have been determined in the soils from caly loam region in west AL-Fashir city, Western Sudan. The top soil of this region is predominantly loamy sand. The soil pH varies within the acidic or slightly neutral and range between 6.62 – 7.72. The EC values were found to vary between 0.155-0.360. OC is very low (mean 0.081±0.007). MC range between 0.230 – 0.430%. Average trace element concentrations decreased according to: Fe-Co-Ni-Cr-Zn. The sub-soil of this region is predominantly loamy sand. The soil pH varies within the range 6.02-7.10. The EC values were found between 0.162-0.275. OC is very low (mean 0.093+0.020). MC range between 0.230-0.430%. Average trace element concentrations decreased according to: Fe -Mn-Cr-Zn. The t-test showed that, elemental pairs: Ni-Cd, Cd-Cr, Mn-Cr, Pb-Cd, Cu-Cr, Cu-Cd, Cu-Mn, Zn-Cd, Fe-Mn, Fe-Pb, Fe-Cr, and Fe-Mo were showed significant differences in their concentrations in the study region, top-soil. In the top-soil, pH was high positively correlated with silt (r=0.760), whereas in the sub-soil, pH was highly positive correlated with EC (r= 0.755). The extraction of trace elements from soils of North Darfur for industrial use (especially, Fe, Cr and Cu) should be investigated.

The Organization of American Historians (OAH) and theJAH have done many wonderful things in recent years, but "What Do American Historians Think: A Survey" is not one of them. This project is a colossal exercise in banality. The finding that historians hope to contribute something to "human wisdom" and believe they should try to discover "new sources and/or information about the past" is about as interesting as would be a study revealing that tentmakers hope to keep campers dry. That "diversity" should be found to be valued highly by members of an organization that has spent the past two decades celebrating it should come as no surprise. That "intolerance, ethnocentrism, and racism" should together constitute a "dark spot in American history" in the eyes of a profession that has expended much of its energy in the critical exploration of this failing is, again, to be expected. And one might ask, parenthetically, if the history of the United States is best understood as the morality play implied by the terms "dark spot" and "bright spot"? That many Ph.D.'s say grumpy things about the "hoops" they had to jump through in graduate school will surely glaze the eyes of even the most alert and conscientious member of the Committee on the Future of the Graduate Program. But what is banal to some may be encouraging to others. The survey may give heart to extreme anti-elitists, eager to cut down to size those professors who think themselves intellectually superior to the average reader of the Sunday supplements. Readers of a journal ostensibly oriented to the interests of learned specialists are now soberly invited to answer Parade-magazine style inquiries into "what person in American history" we "most admire." Is American history a repository for inspirational models, as this phrasing implies? Those willing to play this game answer predictably enough: the winner of this popularity contest is Abe Lincoln. And so with commercial motion pictures: what is our "favorite movie" about the United States? Why, Gone with the Wind, of course. Why "favorite"? The word does not take us very far. How different the survey's results might have been-and how much more potentially revealing of historians' attitudes had the question been formulated to take account of distinctions masked by "favorite." Is a movie (or novel -the same query applies to the survey's question about novels) being considered simply as a meaning-rich historical artifact or as an expression of insights about history with which the historian agrees? After all, many novels and commercial motion pictures do display sound ideas about the


The paper by Chatzidimitriou-Dreismann, Gray and Blach in the title reports measurements on gaseous hydrogen, performed on the VESUVIO electron volt neutron spectrometer at the ISIS neutron source. It was claimed in this paper that the VESUVIO measurements show that, if the energy transfer is sufficiently large that the bond in the H2 molecule is broken, then a larger energy transfer than that predicted by conventional neutron scattering theory occurs. It was also claimed that this is the first evidence for an increase in the energies of the proton and its environment due to quantum disentanglement. It is shown here that this evidence is almost certainly a spurious consequence of errors in the data analysis of Chatzidimitriou-Dreismann et al. When the standard VESUVIO instrument programs are used to analyse the same data on gaseous hydrogen the results obtained are in very good agreement with conventional theory.


Engineering geology is an important compulsory professional basis course for the urban underground space engineering. Its teaching hours is a few but rich in content. This course pays equal attention to theory and practice, whose teaching is difficult and endowed with challenging. In order to adapt to the deep, large and especial construction for urban underground space engineering, we must reform the practice and teaching system of engineering geology. The reformed course is closely combining with the construction practice of underground engineering and reflecting the latest academic achievements. We strengthen the practice and open teaching, focus on training students' innovation ability and innovative thinking in the teaching process.


Voting trust is a legal system and legal means which applies the trust principles into the field of performing the voting right in the stock corporation.There is neither the statutory law of voting trust,nor the prohibitive regulation of the exertion of such right in China.Probing into the legal force questions about voting trust,the purpose is to make the voting trust system into the real life so that it can play a positive role in the social economy of our country.


Emergence of new resistant strains of microorganisms to current antibiotics has become a major issue in public health; therefore, it is imperative to develop new bactericides. This study, thus, aimed at synthesizing silver nanoparticle (AgNPs) and determining their antibacterial activities on bacterial biofilms. Sachet water and well water samples were collected from sachet water industries and two hand-dung wells around Gbonagun piggery house, respectively from where isolation and identification of microorganisms was carried out using standard techniques. Identified bacterial isolates were screened for biofilm formation using tube test as well as Congo red method and the fungal isolate was used to synthesize AgNPs. The formation of silver nanoparticles was confirmed by the physical change of colour and absorption peak between 250-800 nm was evaluated using UV-Vis spectroscopy. Further, the synthesized AgNPs were characterized by Fourier transform infrared spectroscopy. Antibacterial activities of the silver nanoparticles on the biofilms formers was investigated using agar well diffusion method and the potential to prevent the growth of biofilms was evaluated. Predominant bacterium and fungi were Bacillus subtilis and Aspergillus species. Biofilm formers as revealed by the tube test and C ongo red method are: B. subtilis , Enterobacter cloacae, Proteus mirabilis, Klebsiella pneumoniae, Streptococcus pyogenes and Staphylococcus aureus. The color of the synthesized silver nanoparticles by A. niger was yellowish brown and control showed no colour change. The UV-visible spectra of the nanoparticles exhibited an absorbance peak at approximately 425 nm. The FTIR analysis revealed the presence of coordinating NH 2 , OH, amides I and II among others, ligating functional groups in the biomass of A. niger responsible for efficient capping and stabilizing of the AgNPs. Synthesized AgNPs prevented the growth of biofilm formers by exhibiting highest zone of inhibition of 18.5 mm. The ability of the synthesized silver nanoparticles to inhibit growth of bacterial biofilms by Bacillus subtilis presents the mould ( A. niger ) as a vital bioresource in synthetizing AgNPs with good bactericidal activities.


The most important kaolin deposits from Campo Alegre region (SC) were formed by the conjunction of at least one hydrothermal phase, followed by several supergenic weathering phases. Possibly deposits formed by only one of these processes exist, but these deposits shall be small and smaller than those mined today. Besides kaolinization, illitization/muscovitization and silicification, hydrothermalism also generated pyritized and propilitized zones, with quartz + chlorite. Together, hypogenic alteration related to kaolin deposits are very similar to alteration realted to high sulfidation epigenetic volcanogenic gold deposits. Most part of the biggest kaolin mines from the southern part of Campo Alegre Basin are distributed along a 13 Km long and 1,5 Km width bent zone that is parallel to structural alignments that point out the eastern border of the basin. This zone was originated by deformation that has folded and broken rocks, generating a fault system alongside and parallel to structural lineaments. This fault system has made possible the ascent of hydrothermal hot aqueous fluids and of diqueform intrusions that caused hydrothermalism genetically related to kaolin deposits. Gammaspectrometry may indicate hydrothermalized zones. Although the potassium equivalem rock contents, derived from aerial gammaspectrometry of the mine regions, varie from a minimum of 2,07% to a maximum of 4,00%, 17 of the 20 mines are on high grade regions, with equivalem potassium contents grater than 3,04% and lower than 4,00%. The "F factor" (= (K.U)/Th) seems to indicate hydrotherrnalized zones better than potassium equivalent rock contents. Practically ali the biggest mines on region are placed where "F factor" is large, bigger than 10,22% and lower than 15,47%. The biggest mines are also restricted to regions with altitudes between 960 and 1060 m, and were indicated by kaolin occurences on surface. These controls were considered to be diagnostic factors, and taken into consideration to calculate the weights of the Favorability Index. The distribution of favorability index was expressed as a Favorability Map that shows areas with greater possibilities to have kaolin deposits.

Air pollution exposure is related to increased cardiovascular morbidity and mortality. Factors that trigger this event are important for public health, whereas in the mean time epidemiological evidence implicates particulate matter (PM) as a cardiovascular risk factor. Still, the mechanism of this cardiovascular injury is still unclear. Oxidative stress is the main mechanism that explains biological process as a result of PM. On inflammation pathway there will be find increased TNF-a as a response to PM exposure.The aim of this study was to describe the effect of soot particulate exposure on TNF-a expression in mechanism of cardiovascular disorders. Experiments were performed on white female rats (Rattus novergicus) divided into 3 groups control group (P0) (n=12), without exposure to soot particulate; treatment group 1 (P1) (n=12), exposed to soot particulate concentration of 532 mg/m3one hour/day for 30 days; and treatment group 2 (P2) (n=12), exposed to soot particulate concentration of 1064 mg/m3 one hour/day for 30 days. Immunohistochemical staining was used to quantify the expression of TNF-a in cardiac tissues. We quantified the expression of TNF-a by immunoreactive index score (IRS).Increased TNF-a expression on P2 is more significant (p=0.016) compared to P0. But there's no significant difference between P0 and P1 (p=0.660), and such with P1 compared to P2 (p=0.81).Exposure to soot particulate significantly increased expression of TNF-a in subjects. Our findings suggest the role of activation inflammatory pathways in response to soot particulate exposure in cardiovascular disorders. (FMI 2012;48 186-189)


Ensuring that family planning service providers have the necessary support to offer quality services is a challenge for program managers. Most programs do not have adequate resources to provide refresher training follow-up and supervision to their service providers which can result in poor quality of care. As the Institute for Reproductive Health at Georgetown University has worked with NGOs and ministries of health around the world to scale up the Standard Days Method® (SDM) a consistent challenge has been obtaining follow-up support for providers. To address this issue the Institute developed an instrument called the Knowledge Improvement Tool (KIT) which allows supervisors to quickly identify gaps in knowledge of SDM providers allowing them to provide targeted effective support during routine supervisory visits. Operations research has demonstrated the effectiveness of the KIT in improving and maintaining SDM providers knowledge. However in practice the KIT has been applied in different ways: individually in group settings and provider to provider. The objective of this study was to assess the cost effectiveness of these different approaches and compare it to taking no action at all. The study showed that follow-up is necessary and that the most cost-effective approach is the group KIT refresher training. Programs which already actively supervise service providers through an individualized approach should consider a similar strategy for SDM providers using the KIT as this strategy yielded superior results in terms of provider competence.

Until recently, organic vapor sensors using liquid crystals (LCs) have employed rigid glass substrates for confining the LC, and bulky equipment for vapor detection. Previously, we demonstrated that coaxially electrospinning nematic LC within the core of polymer fibers provides an alternative and improved form factor for confinement. This enables ppm level sensitivity to harmful industrial organics, such as toluene, while giving the flexibility of textile-like sheets (imparted by polymer encapsulation). Moreover, toluene vapor responses of the LC-core fiber mats were visible macroscopically with the naked eye depending on the morphology of the fibers produced, and whether they were oriented in specific geometries (aligned, or random). We identified two types of responses: one corresponds to the LC transition from nematic to isotropic, and the other we suggest is due to an anchoring change at the LC-polymer interface that influences the alignment. While we need to study the presence that defects can have in more detail, we noted that fiber mat thickness is crucial in attempting to understand how and why we are able to visualize two responses in aligned LC-fiber mats. Ultimately, we noted that the response of the polymer sheath itself (softening) to organic vapor exposure affects the liquid crystal confinement in the core. From the microscopic point of view, this will influence the threshold concentration that fibers in a mat will overall respond to. In this paper we will discuss three findings the morphologies enabling LC-core fiber mat response to vapor seen both micro- and macroscopically, how thickness of the fiber mat can play a role in the visualization of the responses, and the effect that the polymer structure has in the mat's sensitivity threshold.

Abstract : Engineers at the Vicksburg District (MVK) of the U.S. Army Engineer Division, Mississippi Valley (MVD), are responsible for the design and construction of levees all along the Mississippi River and its tributaries within the District's boundaries. The local Levee Boards are responsible for maintaining approximately 990 miles (1.6 million meters) of unpaved roads, and the District is responsible for maintaining approximately 390 miles (627,000 m) of unpaved roads that reside on top of the levees. Over the years, the MVK has developed its own specifications to meet these needs. Historically, MVK has relied upon sources of sand clay-gravel that could provide consistent products. However, these sources are becoming depleted, so the products have recently become inconsistent. As a result, the MVK has expanded its specifications to facilitate bid submittal by producers of crushed aggregates. The purpose of the investigation reported herein was to improve the MVK, MVD, specifications by characterizing various aggregate types in the laboratory, along with collecting performance data under traffic. Because of MVK's recent struggles in finding consistent aggregate sources, both natural and crushed sources of aggregate were included in this study. Trafficking and performance monitoring were accomplished under controlled test track conditions. A review of specifications used by other agencies was also conducted in order to take advantage of their knowledge.

The next stages of EU integration in terms of deepening or in terms of enlargement imply the need for reliable knowledge about the compatibility of national cases either to enhance cohesion or to promote further Europeanization where it has been lagging so far. This is why measuring the sociopolitical differences between countries experiencing EU integration is a vital premise for maximizing the Union's capacity for enlargement. The cognitive challenge is to find a way to depict the national societies comprehensively, and in detail, whilst at the same time providing a basis for comparing the different countries. Arguably, the current approach of the European Commission has proved insufficient in providing strong analytical instruments to reflect the specific national contexts and potentials for European integration. In this paper we propose a new, complex quantitative approach to the problem based on cluster analysis of the indicators covered by the Open Society Catch Up Index over a period of four years from 2011 to 2014. The result of our analysis is a structural typology that splits the 35 European member and applicant countries into three sociopolitical clusters which do not coincide with the standard formulaic dichotomies regarding older member states (OMS) / new member states (NMS), Western / Eastern European countries and the like. Although the instrument registers some dynamics in time, the clusters remain stable. In order to illustrate the heuristics of the specially devised analytical instrument we carry out a comparison among four South-East European societies which are particularly significant from the point of view of the EU's enlargement policy. A detailed comparison shows that Bulgaria and Romania, which received a special, common conditionality treatment by the EC in the form of the Cooperation and Verification Mechanism (CVM), are typologically similar. Croatia, which was spared the implementation of the CVM, outperforms the other three, while Turkey – which is still negotiating its EU accession – follows a unique development path, diametrically different from the rest. Therefore, we provide empirical support for the assumption that the EU should continue implementing a differentiated policy approach to the integration of the South-East European candidates.

In the actual world, computer plays a key role nowadays. A lot of research has been done in consumer behavior. The study identifies various factors that influence consumers to purchase a personal computer. This paper tries to explain it focusing on the consumer buying decisions for personal computers and the impact of the factor on buying personal computer and an attempt to explain some factor i.e. Pre purchase information, source of information, sources of repair, satisfaction level towards existing brand, probable reason to change and other factors could have influence in the buying choice. These questions raised curiosity to do a study on the buying behaviour of the students.


India is a fast growing economy and emerging to be a global leader. The energy requirement for any evolving nation is on the rise. Over dependence on diminishing fossil fuels has cost us pollution and its after effects as the reward. Wind energy is emerging to be one of the leading power sources from natural resources. New and improved methods of harnessing wind energy are being developed. Conventional windmills although much in use have their own limitations in installation and maintenance. Bladeless windmills can overcome these limitations and harness wind energy more efficiently and cost effectively. This journal paper depicts the principle of working and the output obtained from the prototype of a bladeless windmill.


This study examines the effect of audit quality (AQ) on the earnings response coefficient (ERC) based on a sample of 1,884 firm-year observations comprising 471 firms listed on the Bursa Malaysia from 2007 to 2010. This study tests whether AQ affects ERC after controlling the established determinants of ERC: beta, growth, earnings persistence, and size. Using reverse regression, the study confirms that Big 4 is significant and positive to ERC. Auditor switching from non-Big 4 to Big 4 indicates the same results; however, the switching of auditors among Big 4 is not significant. The study thus provides systematic and comprehensive additional evidence on the effect of AQ via the measurement of Big 4; and auditor switching from non-Big 4 to Big 4 and switching among Big 4 on ERC. This is an important contribution to the literature but especially so given that the evidence comes from Malaysia, an emerging economy, whereas the existing empirical literature relates mainly to the developed countries.

The purpose of this article was to assess the legitimacy of introducing Article 244c into the Criminal Code. It provides for the possibility of punishing a person who evades to fulfill of a compensatory measure in the form of a duty to redress damage or make restitution, ordered by the court in favour of the wronged party, for a crime prosecuted by public indictment. The regulation was analysed using the formal-dogmatic method, in order to verify whether the introduced provision is consistent with other solutions of criminal law and whether it does not contain any constructional errors. As a result of this analysis, it was concluded that this regulation cannot be reconciled with the nature of redress damage as a compensatory measure. Overly far-reaching penalisation has led to excessive differentiation of the effects of imposing the duty to redress damage on the perpetrator as a compensatory measure and as an effect of allowing a civil action and has led to many systemic inconsistencies related to the imposition of the duty to redress damage in criminal law. The regulation itself, on the other hand, is not very precise and does not properly define when the offender's fulfilment of the elements of this criminal act occurs, which is its fundamental error.

A formalism is described that greatly simplifies the derivation of scalar, electromagnetic, and gravitational self-forces and self-torques acting on extended bodies in curved spacetimes. Commonly-studied aspects of these effects are normally dominated by the so-called "regular" component of a body's self-field. The only consequence of the remaining (much larger) portion of the self-field turns out to be very simple. It exerts forces and torques that effectively renormalize all multipole moments of the body's stress-energy tensor in its laws of motion.

Introduction and Aims: Acromioclavicular dislocations and fractures of the distal clavicle present a challenging problem for the treating surgeon. The use of a new specifically designed implant was investigated. A hooked-shaped plate with fixation to the distal clavicle and 'hook' placement under the posterior acromion was used. Method: The procedure was carried out on eight patients. In five patients the injury was a fractured distal clavicle. In three cases an acromioclavicular dislocation was treated. In all cases the time to returning to a functional capacity was analysed. The eventual functional result was indexed from the time of fracture union or complete stabilisation of the dislocations. Results: All five fractures went on to anatomical union. The three dislocations were all stabilised with no instability or subluxation. In two cases patients complained of impingement symptoms with decreased overhead functional capacity. In both cases the patients regained a full and pain-free range of movement after removal of the implant. Conclusion: This new implant provides an acceptable alternative in the management of distal clavicle fractures and acromioclavicular dislocations. The complication of impingement is encountered, but this appears to be treatable by removal of the implant after fracture union or joint stabilisation.


Abstract First Nations and Métis women in Canada experience increased risk of poor health outcomes in pregnancy compared to non-Aboriginal women. There is limited literature on the availability and use of physical activity (PA) and obesity prevention resources for Aboriginal women during pregnancy, which are important components of prenatal health care. This paper aims to demonstrate how community-based participatory research (CBPR) led to the development of a resource for urban Aboriginal women to support them in being physically active and preventing excessive weight gain during pregnancy. Participants, who included pregnant or postpartum women and care providers who serve Aboriginal women during pregnancy, indicated a lack of access to relevant pregnancy resources. Participants suggested the development of a culturally safe online pregnancy application created for/with urban Aboriginal women in Ottawa. We contend that CBPR is an effective approach to health promotion and technology development that can lead to community-generated, culturally safe, relevant, and creative health interventions.


Recycled steel is a key material for sustainable development. However, not all steel demand can be met by recycling, and therefore new metallic iron must be introduced in the global cycle. The transformation of iron oxides into steel requires carbon which is oxidized into CO2. This paper focuses on the basic oxygen furnace (BOF) where molten iron is transformed into liquid steel. The process is modelled using mass and energy balances in order to assess the effect of molten iron temperature on CO2 emissions. Model results show that, for a typical converter charge, a slight change of 10 °C in the hot metal temperature can led to a direct variation of 0.01 t of CO2 per ton of liquid steel. Finally, different actuation levers for carbon mitigation are suggested. It can be concluded that operation and modelling improvements should be jointly addressed to exploit their full potential for carbon footprint reduction.

The use of IoT technologies has increased from 13 percent in 2014 to about 25 percent today. And around the world number of IoT-connected devices is expected to increase to 43 billion by 2023, a threefold increase from 2018. IoT will continue to grow in device numbers and use cases, but organizations must reckon with the security and interoperability challenges that have plagued the market since the beginning. Building robust IOT applications by incorporating security features has become a necessity. Thus, in this article, an edge-driven security framework architecture is described for intelligent IoT systems. A security framework contains all standard security features required by an application such as authentication, authorization, secure connection etc. We introduce the architecture of edge-driven intelligent IoT, and present typical edge-driven intelligent IoT applications. Second, we point out the security threats in edge-driven intelligent IoT in terms of attack behaviour of adversaries. Third, we develop a case study of edge-driven intelligent IoT from the security perspective. Our focus is to develop a middleware or framework between the Users and IoT Environment to ensure users are connected to IoT environment upon authentication for a contract session and create secure communication via cloud between the users and IoT environment


Traditional network management can not meet the needs of the Next Generation Network(NGN),so service-oriented network management is the inevitable development trend.Based on the research of active network technology and using advanced ideas of active network technology and telecommunication management network,we proposed the organization model,the function model,the communication model and the information model.To propose a new network management model: service-oriented network management model based on active network technology.The network management system based on this model can preferably and effectively manage network services.


Abstract Meaning Representation (AMR) parsing is the task of translating a sentence to an AMR semantic graph which captures the basic meaning of the sentence, and is empowered by pre-trained Transformer models recently. These models encode the syntactic and semantic knowledge implicitly through self-supervised pre-trained tasks. We argue that encoding the syntactic and semantic knowledge explicitly is beneficial to AMR parsing and can improve data efficiency. Specifically, syntactic dependency and semantic role labeling (SRL) have similar sub-structures with AMR. In this work, we propose a novel linguistic knowledge-enhanced AMR parsing model, which augments the pre-trained Transformer with syntactic dependency and semantic role labeling structures of sentences. By applying a heterogeneous graph attention network, we can obtain syntactically and semantically augmented word representation, which can be integrated using an attentive integration layer and gating mechanism. Experimental results show that our model achieves state-of-the-art performance on different benchmarks, especially in out-of-domain and low-resource scenarios.


In order to understand the basic process of natural rehabilitation of vegetation and variations of diversity of species of Wuqi County,it studies the plant community that had been banned for years in Chaigou Watershed of the county.The outcomes show that the plants of the watershed mainly are Artemisia scoparia、Lespedeza davurica、Leymus secalinus、Tripolium vulgare,the succession rule of vegetation on the south slopes is Artemisia scoparia+Setaria viridis+Corispermum stauntonii→Leymus secalinus+Artemisia scoparia(Lespedeza davurica、Tripolium vulgare、Cleistogenes squarrosa)→Lespedeza davurica+Leymus secalinus(Thymus mongolicus、Artemisia frigida、Incarvillea sinensis、Tripolium vulgare)and the succession rule of vegetation on the north slopes is Artemisia scoparia(Lespedeza davurica、Leymus secalinus) →Tripolium vulgare(Artemisia frigida).All the degrees of abundance,diversity and equitability of species of community on the north slopes of the watershed are higher,that of the south slopes lower and the abundance degree of the mixed forest region is the maximum and the degree of equitability minimum.

The Layla Lakes in central Saudi Arabia, located 300 km south of Riyadh, are fed by groundwater, but dried up in the late 1980's due to extensive groundwater use, revealing a series of 23 sinkholes in the Jurassic Hith formation. In one of them with a size of 400x100 m and a depth of 10 m several samples were taken during a field campaign in 2011. Furthermore a sediment core was drilled near the sinkhole, revealing a lacustrine succession of 10.8 m. Mineralogical and geochemical analyzes show two distinct types of sedimentation: Sediments with an average con- tent of 85% calcite (carbonates) and sediments, which consist almost entirely of gypsum and anhydrit (sulfates). The carbonates precipitated when the exchange between groundwater and lake water was too large to achieve supersaturation of gypsum, while the sulfates mark periods of strong evaporation with limited rates of water exchange. First radiocarbon ages of mollusc shells and U/Th dating of carbonates indicate that the sedimentary succession covers 6000 years. Autochthonous microfossil assemblages comprise pollen, spores, diatoms, freshwater algae, testate amoebae, phytoliths and other non-pollen palynomorphs and offer the application of various multi-proxy methods to reconstruct palaeoclimate and palaeoenvironment in the center of Saudi Arabia in detail, a region, where such a complete sedimentary record is unknown so far. First XRF and visual analyses of sediment composition show at least four changes between arid and more humid phases based on the frequency of carbonate and sulfate sediments. A first palynological analyses show that during the humid phases the groundwater inflow was higher than the loss of lake water by evaporation. With increasing lake level large floodplain environments evolved, which were covered by a vegetation mainly composed of grasses and sedges. During dry phases the lake level decreased significantly and the vegetation was replaced by plants that were adapted to arid conditions.


Objective:To investigate the indications and surgical methods of mini-invasive laparoscopic techniques, including retroperitoneoscopic adrenalectomy and hand-assist laparoscopic adrenalectomy, to adrenal gland tumor.Methods:Eighteen cases with tumor size less than 6cm received retroperitoneoscopic adrenalectomy, while 3 cases with size ranged from 10cm to 17 cm were treated with hand-assist laparoscopic adrenalectomy. The operating time, blood loss, postoperative intestinal function recovery and hospital stay were observed.Results:Of all 21 cases, 20 were performed successfully. In retroperitoneoscopic group, the operation time was 82.8 ± 31.1 min (ranged from 25 to 135min) and the blood loss was 113.4 ± 31.8 ml (ranged from 65 to 160 ml). In hand-assist laparoscopic group, the operation time was 180, 200 and 210 min, respectively; and the blood loss was 80,170 and 600ml respectively. The postoperative hospital stay was 3 to 7 days in all cases.Conclusions:Laparoscopic adrenalectomy has less trauma to the patients, with less blood loss and quicker recovery in the same time. The hand-assist peritoneoscopy is a new mini-invasive method to great adrenal gland tumor.

In this paper, we examine the Rules of Origin (ROOs) in Korea's existing FTAs and explore the ROO-related issues in terms of the use of FTAs by analyzing the results of firm survey conducted by Gallup Korea. First of all, this paper addresses growing concerns regarding the complexity and inconsistency imposed by the ROOs in Korea's existing FTAs. By examining the ROOs in seven FTAs, which Korea has concluded or entered into force, we find out diversity across FTAs. Such diversity creates inconsistency in Korea's FTA rules of origin, which implies that local firms have to follow different criteria to meet originating status across FTAs. That is, the operational complications stemming from different ROOs lead to higher compliance costs for local firms, which are likely to exceed benefits from FTA preferences. Therefore, firms may eventually give up on the use of FTA preferences. In this respect, this study emphasizes the importance of building Korea's own position on the ROOs and applying them to the remaining FTAs. It would help Korea to maintain consistency of its ROOs in future FTAs, which leads to reap full benefits of the multiple FTAs. In building Korea's position on FTA rules of origin, emphasis is placed on to provide supportive system for firms to acquire proper and practical information about the FTAs, to maintain consistency vis-a-vis ROOs in the existing FTAs, and to improve the domestic regime related to the ROOs.


Recent arguments that employment growth occurs disproportionately at small establishments are fundamentally misleading because they confuse regression to the mean with structural shifts in the size distribution of establishments and with an aging effect within cohorts.


Background: Stress gastritis continues to occur in critically ill patients especially when prophylactic measures are not used. Even with prophylaxis, clinically important bleeding occurs in 2 to 4% of patients. Objective: To compare effectiveness of histamine-2 (H2) blockers and proton pump inhibitors (PPIs) as prophylactic agents for stress gastritis. Design: Meta-analysis of English articles where selection criteria initially identified 1213 studies. Participants: 936 patients in 7 randomized controlled trials. Methods: All studies compared PPIs to an H2 blocker. Efficacy was measured by incidence of stress gastritis bleeding. Safety outcome was measured by the rate of pneumonia and mortality. Quality of the study was ranked using Jadad criteria. Of trials, 3 reported on the use of enteral nutrition. A definition of upper gastrointestinal (UGI) bleeding was defined in 5 trials and 6 trials reported pneumonia rates. Sensitivity analysis was performed to help identify heterogeneity. Results were reported as pooled risk difference between the two different drug classes. Omeprazole was used in 6 studies and pantoprazole in one study. H2 blockers used included ranitidine, famotidine, and cimetidine. Most studies had 30 patients per study arm with only 1 study having >100 patients in each study group. Results: Pooled risk difference for UGI bleeding was -0.04 favoring PPIs which was not statistically significant. However, there was significant heterogeneity among studies. Sensitivity analysis revealed little effect on results except when the largest study was removed, which reduced heterogeneity and shifted reduced the risk difference between the 2 drugs. Risk of pneumonia ranged from 3 to 18% and there was no difference in rates based on which drug was used. Mortality was also not different. Of studies, 3 were poor quality and 4 had a Jadad score consistent with good quality. Conclusions: Current evidence does not support an effectiveness difference between H2 blockers and PPIs when used for stress gastritis prophylaxis. Reviewer's Comments: H2 blockers and PPIs are equally as effective for preventing UGI bleeding from stress gastritis and neither is associated with an increased rate of pneumonia. I doubt this article will change a lot of minds on this topic. Current data are not great and the authors ask for the proverbial large randomized clinical trial. I doubt that will happen. Our approach is more pragmatic. A cost consideration drives our choice of agent. We use H2 blockers as the least costly drug in our pharmacy. If PPIs become the least costly agent, I suspect we will change. We use stress prophylaxis only for high-risk patients and stop the drug when risk characteristics of the patient change. Attention to these details will avoid drug cost and risk in many patients. (Reviewer-John A. Weigelt, MD).


The invention provides an intelligent heating solar water heater, which mainly comprises a heat collector, a heat-preservation water tank, an electromagnetic valve, a water level sensor, a water temperature sensor, a water pump, an instantaneous electric heating tube, an electronic water meter, a running water pipe, a water pipe and a controller. The water heater has the advantages of preventing freezing in winter, preventing scaling in summer, combining the advantages of heat-storage type and instantaneous electric water heaters, saving conventional energy resources to the utmost extent and avoiding wasting cold water because cold water in a pipeline returns to the heat-preservation water tank before water consumption, along with high thermal efficiency.


The presented research focuses on the use of thermography to observe influences of different influencing factors on the changes of lower body temperatures. Based on the outcomes of the research fit of garment plays an important role for the retention of heat between the textile material and skin, especially in the zone of both upper and lower shin. Also only tight model of trousers is capable to preserve the temperature in zones of thigh and knees of male volunteer. The given body-maps present differences in values of average temperatures (ΔT) considering the garment fit. In the indoor environment, tight model of female trousers has significant influence on the average temperature in the zone of upper shin. This observation is even more pronounced in the outdoor environment. For the male volunteer, higher differences, between temperatures are seen in the outdoor environment only.


This study aims to identify the resilience of Islamic commercial banks and examine the internal factors of Islamic banks that are thought to influence them. The resilience of Islamic commercial banks was identified using a modified banking crisis index (IBC) formed from the CAR and NPF ratio proxies, while hypothesis testing used WarpPLS as a tool to partially see the effect of Third-Party Funds, FDR, ROA, and BOPO to IBC. The sample of this research is 8 national private Islamic commercial banks in Indonesia for the period 2013-2020. As a result, 2019-2020 is a condition that has been identified as unable to withstand the crisis due to the disruption of the intermediation function. The results of the path analysis show that TPF has an insignificant negative effect, FDR has a significant positive effect, ROA has a significant negative effect, and BOPO has a significant negative effect on the Banking Crisis Index.

Abstract
 Conservation Agriculture (CA) promotes soil health, but issues to do with soil health are poorly researched in the Eastern Cape, South Africa. This study reports on findings from a field trial done on the effects of tillage, crop rotations composed of maize (Zea mays L.), wheat (Triticum aestivum L.) and soybean (Glycine max L.) and residue management on a number of soil health parameters such as carbon (C)-sequestration, CO2 fluxes, enzyme activities, earthworm biomass and the Soil Management Assessment Framework soil quality index (SMAF-SQI). The field trial was done in a semi-arid region of the Eastern Cape Province, South Africa, over five cropping seasons (2012-2015). It was laid out as a split-split plot with tillage [conventional tillage (CT) and no-till (NT)] as main plot treatment. Sub-treatments were crop rotations: maize-fallow-maize (MFM), maize-fallow-soybean (MFS); maize-wheat-maize (MWM) and maize-wheat-soybean (MWS). Residue management: removal (R-) and retention (R+) were in the sub-sub-plots. Particulate organic matter (POM), soil organic carbon (SOC), microbial biomass carbon (MBC) and enzyme activities were significantly (p < 0.05) improved by residue retention and legume rotation compared to residue removal and cereal-only rotations. Also, carbon dioxide (CO2) fluxes under CT were higher compared to NT. The calculated soil quality index (SQI) was greatly improved by NT and residue retention. MWM and MWS rotations, in conjunction with residue retention under NT, offered the greatest potential for building soil health. Residue retention and inclusion of soybean in crop rotations are recommended for improving soil health under CA systems in the semi-arid regions of South Africa.


We present results of supracondylar nailing in six patients who suffered distal femoral fractures above total knee arthroplasty. The average age of patients was 68 (42-92) years. All six fractures healed in a satisfactory alignment in an average duration of 14.6 weeks. There were no wound infection, loss of reduction or implant failure. All patients had regained their previous range of movement of the knee joint at an average follow up of 20 months. Supracondylar nailing is a good method of treatment of a displaced periprosthetic fractures proximal to total knee arthroplasty.


A new functional triphenylamine-based (TPA-based) aromatic polyether (OXPE) derived from 2,5-bis(4-fluorophenyl)-1,3,4-oxadiazole and 4,4′-dihydroxytriphenylamine and polyester (6FPET) derived from 4,4′-(hexafluoroisopropylidene)bis(benzoyl chloride) and 4,4′-dihydroxytriphenylamine were synthesized and used for memory device applications. To get more insight into the relationship between the linkage group and memory behavior, polyamide 6FPA, polyimide 6FPI, and the corresponding isomer 6FPI′ were also synthesized and their memory properties were investigated. The linkage effects of polyether, polyester, polyamide, and polyimide are expected to reveal different retention times of the synthesized polymer memory devices due to their different structural conformations, dipole moments, HOMO, and LUMO energy levels. OXPE, 6FPA, and 6FPET with a non-planar linkage structure but different LUMO energy levels possess SRAM behavior with different retention times, 2 min, 5 min, and 6 min, respectively. 6FPI with a planar linkage group exhibits DRAM property while the corresponding isomer 6FPI′ reveals insulator behavior due to the difficulty in sustaining the charge transfer complex. Furthermore, to illustrate the linkage and acceptor effect systematically, TPA-based sulfonyl-containing polymers with the same linkages were also added into the discussion.


The oral stories of the Xukuru Indians of Ororuba (Pesqueira and Pocao/PE) contain everyday events that represent the spaces and moments of sociability they experienced in the Ororuba mountains, as well as the meaning of Cimbres as a reference of mythical-religious memory for the affirmation of their group identity. The fragments collected are both individual autobiographical memories and part of a collective history, where the interviewees, supported by the memory and the shared story about the past, assert their rights as an indigenous people based on what they have experienced, thought and expressed. Key words: history of indigenous people, Xukuru memories, Northeast of Brazil.

Extracts from the pods of Acacia sinuata (Lourr.) Merr were investigated for their anthelmintic activity against Perithima posthuma taking into consideration their traditional use and reported chemical constituents. Various concentrations (10–100 mg/ml) of each extract were tested in the bioassay, which involved determination of time of paralysis and time for death of the worms. The activity of methanolic and ethyl acetate extracts were found to be more significant than the standard even at a dose of 10 mg/ml. Piperazine citrate (10 mg/ml) was used as standard reference and distilled water as control. The preliminary phytochemical screening showed the presence of carbohydrates, alkaloids and saponins.
