Oxygen and sulfur mass-independent isotopic signatures in black crusts: the complementary negative ∆33S-reservoir of sulfate aerosols?

Abstract. To better understand the formation and the oxidation pathways leading to gypsum-forming “black crusts” and investigate their bearing on the whole atmospheric SO2 cycle, we measured the oxygen (δ17O, δ18O and ∆17O) and sulfur (δ33S, δ34S, δ36S, ∆33S and ∆36S) isotopic compositions of black crust sulfates sampled on carbonate building stones along a NW-SE cross-section in the Parisian basin. The δ18O and δ34S, ranging between 7.5 and 16.7 ± 0.5 ‰ (n = 27, 2σ) and between −2.6 and 13.9 ± 0.2 ‰ respectively, show anthropogenic SO2 as the main sulfur source (from 2 to 81 %, in average ~30 %) with host-rock sulfates making the complement. This is supported by ∆17O-values (up to 2.6 ‰, in average ~0.86 ‰), requiring > 60 % of atmospheric sulfates in black crusts. Both negative ∆33S-∆36S-values between −0.34 and 0.00 ± 0.01 ‰ and between −0.7 and −0.2 ± 0.2 ‰ respectively were measured in black crusts sulfates, that is typical of a magnetic isotope effect that would occur during the SO2 oxidation on the building stone, leading to 33S-depletion in black crust sulfates and subsequent 33S-enrichment in residual SO2. Given that sulfate aerosols have mostly ∆33S > 0 ‰ and no processes can yet explain this enrichment, resulting in a non-consistent S-budget, black crust sulfates could well represent the complementary negative ∆33S-reservoir of the sulfate aerosols solving the atmospheric SO2 budget.
CHEESE WHEY AS A NATURAL SOURCE OF PEROXIDASE TO AMELIORATE THE NEGATIVE EFFECTS OF PHENOLIC COMPOUNDS OF FEED INGREDIENTS AND THE GOSSYPOL OF COTTONSEEDS IN RABBITS DIETS.

This study was conducted to investigate the influence of 3 levels of cheese whey as a natural source of peroxidase to overcome the negative effects of polyphenolic compounds naturally found in feed ingredients of rabbit feed. Thirty New Zealand growing rabbits were used. The rabbits were divided according to body weight into 5 similar experimental groups. They were assigned at random to receive the 5 experimental diets. The control ration was a commercial diet. Un-decorticated cotton seed cake partially replaced soybean meal protein in the second diet. The other 3 experimental diets were the same as diet 2 but supplemented with 1, 2, and 3%. of cheese whey, respectively. The experiment lasted for 72 days to study the effects on nutrients digestibility and feeding values, growth performance, and economical efficiency. Results showed that rabbits fed diet containing 3% whey recorded significant increase in digestibility coefficients of DM, OM, CP, CF, EE and NFE compared to the other ratios while diets which contained 2 or 3% whey had higher digestibility of NDF, ADF, hemicellulose, cellulose and lignin. The nutritive value as TDN, DE and ME significantly (P<0.01) increased with 2 or 3% whey. Final body weights were 2545, 2248.33, 2466.67, 2470.50 and 2456.67 g. for animals fed the control, 0, 1, 2 and 3% whey, respectively. Corresponding averages of daily gains were 26.02, 21.78, 24.84, 24.85 and 24.63 g. These results revealed significant (P<0.05) improvement in growth performance in response to whey supplementation. In addition, economical efficiency and relative economic efficiency were the best for the group fed 1% whey (163.41 and 119.27%) followed by the other groups. It was concluded that cheese whey could be used as a natural source of peroxidase to ameliorate the negative effects of phenolic compounds naturally found in feed ingredients and the gossypol of cotton seeds.

Investigating Workload and Occupational Burnout of healthcare workers in the Welfare Organization of Gonabad City

Workers in welfare centers have to work more than other people, which may lead to job burnout. The present study was conducted to analyze the relationship between workload and burnout dimensions among the employees in health centers of Gonabad City, eastern Iran. In this descriptive-analytic study, a total number of 100 healthcare workers from the Welfare Organization of Gonabad City were selected to investigate the association between their workload and occupational burnout using the NASA-TLX questionnaire and the Maslach-Jackson Inventory. The data were analyzed by Chi-square, Pearson correlation, and one-way ANOVA in SPSS 22 software. Among the healthcare workers of the Welfare Organization, nurses had the highest rate of burnout in terms of efficiency (67.9±21.3). They had the lowest rate of burnout in terms of exhaustion and frustration (37.05±24.23), and moderate burnout in terms of mental pressure, physical pressure, time pressure, and effort (63.40± 26.17, 58.75±23.78, 60.30±21.72 and 61.54±26.31). Considering the findings of the study and the importance of the health care profession, it is of the utmost importance to address the problems of healthcare workers in the Welfare Organization. Accordingly, the authorities must take the necessary steps to suit the environmental, managerial, and personnel conditions to them.
Factors that Influence End-Users’ Adoption of Smart Government Services in the UAE: A Conceptual Framework

As mobile government (m-government) services are a new field, there is limited research that identifies the factors that affect the acceptance of smart government (mobile-application-based) services. This study intends to explore the factors that seem to improve end-users’ acceptance of mobile government services. Mobile technologies are one of the pillars of a smart city. Mobile technologies have huge potential to become one of governments’ most effective and efficient tools in offering their services to the public. However, the technologies that are available for use are not fully welcomed by end-users. The key problem associated with the high failure rate of e-government projects is the lack of awareness of the potential factors that may help citizens adopt m-government services. By reviewing the existing work, this paper proposes a framework, as an extension of Davis’s technology acceptance model (1989), to address the factors that influence user acceptance of smart government services in the UAE and thereby guide the successful implementation of smart government. The literature reviewed led to ten propositions that present the main elements in ensuring endusers’ adoption of smart government in the UAE. A framework is developed to highlight the key factors that influence the successful implementation of smart government services. The paper will help in understanding the key issues surrounding mobile applications that may support the successful operation of m-government.
Neural Network Compression and Acceleration: An Overview

A large number of fields (e.g. natural language processing, computer vision) have witnessed the power of deep convolutional neural networks(CNN). However, both training and doing inference are computationally expensive andmemory intensive. Therefore, a growing number of researches are attempting to compress convolutional neural networks, which aimed at accelerating CNN-based models without losing accuracy. These techniques are roughly categorized into four schemes: neural network configuration reset, parameter pruning and sharing, low-rank factorization and sparsity, and knowledge distillation. For methods of each scheme, we provide a roughly insightful analysis regarding their performance, related applications, advantages and drawbacks. After that, we survey the evaluation benchmarks and datasets. Finally, we conclude this paper, discuss remaining challenges and our opinions about the direction in this topic.
Adaptation Approaches for Direct Seeded Rice to Reduce Greenhouse Gas Emission in the Perspective of Climate Change

A field experiment was conducted at research farm, Bihar Agricultural University, Sabour, India during 2017 and 2018 to gain insight crop phonology mediated greenhouse gas emission under different tillage and nitrogen management practices in direct seeded rice (DSR). The experiment was conducted in split plot design with two tillage viz. zero tillage (ZT) and conventional tillage (CT) as main plot and four nitrogen management practices viz. 100% nitrogen through neem coated urea (S1), SPAD based nitrogen management (S2), 75% through neem coated urea + 25% nitrogen through vermicompost, (S3) and ¼ nitrogen as basal and rest in equal three splits at 20, 40, 60 DAS (S4) as sub plot, in three replication. The highest yield (4.69 t ha-1), net return (Rs 46440 ha-1) and B:C ratio (1.44) were recorded from zero tilled DSR. Further, highest yield (4.82 t ha-1), net return (Rs 44880 ha-1) and B:C ratio (1.36) was obtained under split application of nitrogenous fertilizers among other subplot treatments. The range of methane (0.57- 1.47 mg m-2 hr-1) carbon dioxide (0.32- 0.61 mg m-2 hr-1) and nitrous oxide (19.58- 38.79 µg m-2 hr-1) emission was recorded lowest in zero tilled plots and split application of nitrogenous fertilizer also emitted lowest values of 1.59 mg m-2 hr-1 methane, 0.86 mg m-2 hr-1 carbon dioxide and 46.76 µg m-2 hr-1 nitrous oxide at maximum tillering stage of crop growth. Moreover, methane and nitrous oxide emission was gradually decreased from maximum tillering to harvesting stage. Zero tilled DSR with split nitrogen fertilizer application ascribed lowest greenhouse gas intensity among the other crop establishment and nitrogen management options. Thus, zero tilled method of crop establishment with split application of nitrogenous fertilizer could be a remunerative and environmentally stable method for direct seeded rice cultivation.
End-to-end learning of local point cloud feature descriptors

Emerging technologies like augmented reality and autonomous vehicles have resulted in a growing need to identify and track objects in the environment. Object tracking and localization is frequently accomplished through the use of local feature descriptors, either in 2D or 3D. However, state-of-the-art feature descriptors often suffer from incorrect matches, which affects tracking and localization accuracy. More robust 3D feature descriptors would make these applications more accurate, reliable, and safe. This research studies the use of a pointwise convolutional neural network for the task of creating local 3D feature descriptors on point clouds. A network to produce feature descriptors and keypoint scores is designed, and a loss function and training method is developed. The resulting learned descriptors are evaluated on four different objects, using synthetic and scanned point clouds. The evaluation shows that the descriptors can effectively register objects with noise, and that the keypoint scores can reduce the number of required iterations for registration by a factor of three. An analysis of the learned filters provides insights into what the descriptors encode and potential avenues for improvement.
Evidence of criterion validity for the Causal Attribution Scale

This paper reports the study of evidence of the validity of concurrent criterion to the Causal Attributions Assessment Scale for Basic Education (EAVAT-EF). The factors Causes for Success and Causes for Failure constitute the scale. Participated in this study 927 students (3rd to 9th grades, Mage = 11.59, SD = 1.98), mostly girls (53.9%), being 147 retained students. The results indicated the predisposition of Elementary School students to indicate the factor Causes for Success. The girls and non-repeating students scored higher on both EAVAT-EF factors. The Middle School students and the retained students by the criterion of school grade had a higher average in the factor Causes for Failure. As a discussion, we point to teaching-learning particularities between education levels, the possible impacts on causal attributions due to the interaction between the variables gender and repetition, as well as the interference of the disapproved criteria in students’ attributions.
The relationship Between Job insecurity and Sleep Quality: A Moderated Mediation Model

Extant research shows that a variety of job stressors have a detrimental impact on the employee sleep quality. However, it is not yet known about the influence of job insecurity on employee sleep quality. Therefore, this study aimed to address this gap in the literature. Based on conservation of resources theory, we investigated the mediating role of affective rumination and the moderating role of resource management ability. Data analysis of 218 valid questionnaires in China demonstrated that affective rumination mediated the negative relationship between job insecurity and sleep quality. We further found that high levels of resource management ability buffer the positive effect of job insecurity on affective rumination. Finally, we discuss the theoretical and practical implications, and make suggestions for the direction of future study.
Bank Loan Loss Provisioning During Election Years in Nigeria

The paper investigates the behavior of loan loss provisions during election years in Nigeria. Election events create uncertainties in the business environment in Nigeria which can increase the credit risk that banks face. The findings reveal that the banking sector had high loan loss provisions when it is under-capitalised during election years. However, the election year did not have a significant effect on the level of loan loss provisions in the Nigerian banking sector.
Exceptional Case of Hypothermia Induced

Therapeutic hypothermia is a commonly employed and a well-established treatment modality and has proven neuroprotective benefits in patients who have suffered from cardiac arrest following ventricular fibrillation. It can lead to various physiologic changes ranging from metabolic and electrolyte derangements to the ones seen on electrocardiogram. We report the case of a middle aged Caucasian male who was admitted to the Coronary Care Unit after suffering from a cardiac arrest from Ventricular Tachycardia while exercising at a local clubhouse. CPR was initiated by a bystander right away. Upon arrival to the hospital the hypothermia protocol was initiated and his body temperature was lowered to 33 degrees Celsius for a period of 24 hours. What makes our case unique is that there was a transient drop in all cell lines following the initiation of hypothermia, reaching the nadir point on day 5. A few days after the hypothermia protocol was lifted and the patient’s natural body temperature was restored, the pancytopenia began to improve and greatly resolved by the time he was discharged on day 8. To our knowledge there have only been only a handful of cases describing the onset of pancytopenia from chronic exposure to hypothermia in the elderly, malnourished population or from thermoregulatory dysfunction after resection of craniopharyngioma. Our case is therefore a unique presentation that has not been previously reported in the literature. He was a middle aged male who acutely developed reversible pancytopenia from a short-term induction of therapeutic hypothermia. Unlike the other reported cases, our patient did not belong to the extremes of age, was neither malnourished nor had any history of surgeries for craniopharyngiomas, received therapeutic hypothermia for a very short duration of time and did not have any other etiological basis to explain the onset of transient hypothermia. This case emphasizes the need for keeping pancytopenia as a potential adverse effect of short term, mild therapeutic hypothermia.
Serum homocysteine as a predictor of severity of peripheral arterial disease in association with Doppler ultrasonography

Background: To evaluate association between raised serum homocysteine levels and severity of peripheral vascular disease (PVD) and to assess the role of homocysteine as a prognostic marker in PVD and thereby aid in early referrals to prevent cerebral and coronary events in those patients and introduce homocysteine lowering with vitamin therapy as part of medical management in patients diagnosed with PVD.Methods: The serum homocysteine levels was measured in all patients admitted for peripheral vascular disease of upper and/or lower limb and to correlate the above values with Doppler ultrasonography (USG) in the duration between 2016-2018 (18 months). Results: The comparison of homocysteine levels with Doppler shows corresponding significant increase in Serum Hcy levels only in cases of moderate PVD. Statistical analysis with binary logistic regression does show a significant association with moderate severity of PVD and serum homocysteine levels with 66.7% predictability.Conclusions: There was significant association of homocysteinemia only in Moderate PVD with no statistically significant correlation with mild, severe cases of peripheral arterial disease (PAD) and radiological normal cases, further large randomised trials are required to elucidate its clinical relevance in PAD as a prognostic marker of severity.
The Diet Composition of Four Vesper Bats (Chiroptera: Vespertilionidae) from the Centre Region of Cameroon (Central Africa)

Diet is an important part of microbat biology that provides valuable information on how species interact and persist in an ecosystem. Dietary analysis is also important in interpreting their role as predator of night flying insects. Our objective is to report on the food and feeding habits of four microbats (Neoromicia nana, Neoromicia tenuipinnis, Pipistrellus nanulus and Scotoecus hirundo) in the Centre Region of Cameroon, based primarily on fecal remains collected from bats captured at their feeding and roosting sites. Bats were captured from January 2016 to December 2017 using mist nets and their fecal pellets were collected for dietary analysis. Dietary analysis of 393 fecal pellets of 51 vesper bats showed that bats consumed eight insect Orders (Coleoptera, Diptera, Lepidoptera, Hemiptera, Hymenoptera, Isopteran, Trichoptera and Neuroptera). Lepidoptera’s (%v=58.5%) were the most important food source for these bats. The three most frequent insect Orders encountered in the pellets of these bats were Lepidoptera (%f = 96.6%), dipteran (%f =79.1%) and Coleoptera (%f =77.5%). We observed large amounts of Diptera content in the diet of S. hirundo (%v = 39.7%), N. tenuipinnis (%v = 29.6%). Elucidating the role of bats in Dipteran control could lead to benefits for both the conservation of bats and public health. Equally erecting of bat houses to attract bats in farms so that they feed on insects could reduce or minimize the use of pesticides. A statistical analysis of mean percentage frequency and volume of food items indicated that among the four-bat species, consumed prey items were similar (H = 0.2, p = 0.9). This new information can be used for both conservation and to improve public awareness about bats in Cameroon.
CMAR_A_200524 4371..4390

Department of Obstetrics and Gynecology, Beijing Chao-Yang Hospital, Capital Medical University, Beijing, People’s Republic of China Abstract: Poly (ADP-ribose) polymerase (PARP) inhibitors are a class of targeted agents for the treatment of solid tumors. Concurrent PARP inhibition in Breast Cancer Susceptibility Gene (BRCA)-mutated or homologous recombination-deficient tumor cells can induce “synthetic lethality”, which targets two DNA repair pathways and induces serious cytotoxicity to tumor cells without damaging normal cells. Currently, PARP inhibitors such as olaparib, rucaparib and niraparib, which improve progression-free survival, particularly in patients harboring BRCA mutations, are approved by the Food and Drug Administration (FDA) and European Medicine Agency (EMA) for the treatment of ovarian cancers. Based on the results of different clinical trials, the indications for these drugs are slightly different. PARP inhibitors have been studied both as single agents and in combination with chemotherapy, antiangiogenic agents, and ionizing radiation. This review summarizes the critical clinical trials of PARP inhibitors that have been completed, provides an overview of the ongoing trials, presents the confirmed conclusions and notes the issues that need to be addressed in future studies.
Measuring Performance Efficiency of listed Real Estate Investment Trust (REITS) in Sub-Sahara Africa

This paper examines performance efficiency of thirty real estate investment trusts in Sub-Sahara Africa for a three year period of 2014-2016. The study employs the Data Envelopment Analysis (DEA) approach to measure and evaluate the performance efficiency of the REITs. The outcomes show that 23.3% was variable returns (VRS) efficient, 3.33% was constant returns to scale (CRS) efficient and 6.67% was SCALE efficient. These results indicate that listed REITs are not performance efficient primarily because they are a new investment channel that is relatively unpopular amongst investors in sub-Saharan Africa. The study recommends that inefficient REITs should benchmark the efficient ones and the governments should entrench institutional regulations to deepen REIT business.
The relationship between storage and processing in working memory

This thesis reports a series of eight experiments that investigate the detailed nature of the factors underpinning working memory performance in children and adults. Experiments 1 to 3 examined the role of resource-sharing and intrinsic memory demands in complex span performance in 7and 9-year-olds. The results do not support a resource-sharing explanation and are consistent with the view that complex memory span performance is disrupted by processing activities that divert attentional resource from storage. Experiments 4 and 5 investigated the impact of the similarity of processing and storage stimuli on span performance of7to 9-yearold children. The data provide evidence for performance-related decrements under circumstances of stimulus similarity. Experiments 6 to 8 investigated the impact of the lexical status of memory and processing stimuli on children's and adults' complex memory performance with the aim of exploring possible mechanisms of interference in working memory. In 9and 10-year old children and adults, word recall was markedly impaired by monitoring words compared with nonwords. A converse disturbance of nonword recall by nonword monitoring was consistently found for adults, but was either absent or less marked across experiments in the child groups. Overall, the data identify four main factors that mediate complex span performance in children and adults: task duration, attentional resources, taskswitching efficiency, and interference between processing and storage stimuli. The findings are discussed in terms of existing theoretical models of working memory.
