Observation Period

El comportamiento alimentario de larvas del huachinango del Pacífico fue estudiado bajo condiciones controladas, con énfasis especial durante el inicio de la alimentación exógena (al tercer día después de la eclosión). Durante un periodo de cinco minutos fueron observadas de manera individual diez larvas de L. peru, antes y después de ser alimentadas con rotíferos (Brachionus rotundiformis) y nauplios de copépodos (Euterpina acutifrons) en densidades de 5 presas/ml. Para describir parte del comportamiento relacionado con el evento de alimentación se registró el número de veces que las larvas adoptaron una “postura” de ataque, así como el número de ataques por larva a los diferentes tipos presa. Se observó que previo al suministro de alimento, las larvas despliegan tres tipos de conducta: nado, reposo, e impulso rápido. Una vez que fue suministrado el alimento, el patrón de conducta de las larvas cambió, independientemente del tipo de presa. La frecuencia de nado incrementó pero los desplazamientos fueron más cortos y pausas más frecuentes. El periodo de reposo de las larvas disminuyó significativamente y se observaron dos patrones de acción modal asociados directamente al proceso de alimentación: 1) postura sigmoide (“S”), adoptada posterior a la detección de una presa, 2) ataque, evento durante el cual la larva se impulsa espontáneamente en dirección de la presa, independientemente de si se logra o no la captura del alimento. Menos del 50 % de las larvas observadas desplegaron una postura de ataque y el número promedio de ataques por larva durante el tiempo de observación fue menor a 1.5, independientemente del tipo de presa. Los resultados son similares a los reportados para otras larvas de peces durante el inicio de la alimentación exógena y sugieren que los nauplios de copépodos son una presa adecuada durante la primera alimentación de las larvas de L. peru. Feeding behaviour of the Pacific red snapper Lutjanus peru (Nichols & Murphy, 1922) (Percoidei: Lutjanidae) larvae at the onset of exogenous feeding The behaviour of the Pacific red snapper Lutjanus peru larvae during the onset of exogenous feeding at day 3 after hatching at 26º C was studied. Ten larvae were directly observed during 5 min each before and after the addition of feed. Rotifers (Brachionus rotundiformis) and copepod nauplii (Euterpina acutifrons) were used as live feed at a density of 5 prey/ml. Larval behavior was described before and after prey addition. Also, the number of larvae that displayed an attack posture and the number of attacks per larvae during the observation period were recorded. Before prey addition, the larvae displayed three types of conduct: swimming, resting and fast impulse. This behavioral pattern changed with the presence of feed, regardless of prey type. The swimming conduct increased duration but changed to a short distance and frequent pauses. The resting conduct reduced its duration and two new modal action patterns associated to feeding were present: “S” posture after prey detection and the attack which consisted in a direct larval strike towards the prey and may include prey capture. Less than 50% of the observed larvae displayed the attack posture and the mean number of attacks per larvae was less than 1.5 during the observation period regardless of prey type. Results are similar to the reported for other species during the onset of exogenous feeding and suggest that copepod nauplii may be a more suitable prey during first feeding of L. peru.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.

Henry Eccles, in classic studies on logistics, describes the dynamics of strategic procurement in the supply chain stretching from home countries to military theatres of operations. Naval authorities and industrialists concerned with Japanese aggression before and after Pearl Harbor looked towards developing shipbuilding capacity on North America’s Pacific Coast. The region turned into a volume producer of merchant vessels, warships and auxiliaries destined for service in the Pacific and Indian Oceans. Shipbuilding involved four broad categories of companies in the United States and Canada that enabled the tremendous production effort.

This study examined differences in the local government's financial performance before and after the transition from central tax BPHTB be local taxes? In general, this study aims to determine the contribution BPHTB to the PAD as a source of funding for the survival of each region in order to achieve local autonomy system. The samples used in this study is the district/city that has existed since autonomy BPHTB not be treated as 114 cities/districts. The realization of the study observation period is the period before the transition budget BPHTB (Year 2010) and after the transition BPHTB (Year 2011). The research data were statistically tested with a different test of two paired samples. The results show that the performance of local government in Java have differences before and after the transition BPHTB from the central government to local governments. This research can provide empirical evidence of the differences in the financial performance of the post-transition region from the center to the regions BPHTB especially Java. The results of this study can also be used as a reference in future studies with similar themes to consider several things. First, the use of samples that are not confined to the local government but the entire Indonesian island of Java. Second, adding the growth rate ie performance measurement. Third, review the compatibility ratio because in addition to operational expenditure and capital expenditure is no longer heading in the budget expenditure is financing and transfer.     Keywords: Bea Perolehan Hak atas Tanah dan Bangunan, Financial Performance, Autonomous Region.

<p>Goals of the research to analyze whether occurred abnormal return of ASIAN Games phenomena and see how investors react to the big ASIAN Games 2018 event in Indonesia. . This reseach uses a sample of companies included in the hotel, restaurant and tourism sub-sector on the Indonesia Stock Exchange (IDX) during the observation period, based on the purposive sampling method which obtained 22 companies and used the event study method. There is a significant abnormal return but not on the phenomenon of the Asian Games 2018. This shows that investors still wait and see to the organization of the Asian Games in 2018. No difference of abnormal return before and after the Asian Games 2018. This is because, as investors look to the many tourists who have started to flock to Indonesia before the Asian Games in 2018 took place.<em></em></p><p><strong><em></em></strong><em><br /></em></p>

Abstract. North China experiences severe haze pollution in early winter, resulting in many premature deaths and considerable economic losses. The number of haze days in early winter in North China (HDNC) increased rapidly after 2010 but declined slowly before 2010, reflecting a trend reversal. Global warming and emissions were two fundamental drivers of the long-term increasing trend of haze, but no studies have focused on this trend reversal. The autumn SST in the Pacific and Atlantic, Eurasian snow cover and central Siberian soil moisture, which exhibited completely opposite trends before and after 2010, were proven to stimulate identical trends of meteorological conditions related to haze pollution in North China. Numerical experiments with a fixed emission level confirmed the physical relationships between the climate drivers and HDNC during both decreasing and increasing periods. These external drivers induced a larger decreasing trend of HDNC than the observations, and combined with the persistently increasing trend of anthropogenic emissions, resulted in a realistic slowly decreasing trend. However, after 2010, the increasing trends driven by these climate divers and human emissions jointly led to a rapid increase in HDNC.

The New Deal

Today, the anniversary of the death of Franklin Roosevelt, is especially appropriate for a discussion of the political evolution of two territories whose development, before and after his death, was shaped by Roosevelt’s enlightened vision of world public order. The Trust Territory of the Pacific Islands (TTPI) was an inheritance of a war waged by the United States in affirmation of “the right of all peoples to choose the form of government under which they live.” Puerto Rico’s progressive dismantlement of colonial government had its origins in the New Deal. It was furthered by Roosevelt’s support of Puerto Rico’s Popular Democratic Party and a policy favoring self-determination and decolonization entrusted by Roosevelt to a succession of sympathetic and imaginative administrators. Both territories emerged in the postwar period as natural objects of the concern of the world community which Roosevelt helped to organize.

ABSTRACT Objective: To assess the prevalence and magnitude of labial gingival recession (LGR) before and after as well as the incidence during Class II:1 Herbst-Multibracket appliance (Herbst-MBA) treatment (Tx) plus retention in a retrospective cohort study. Materials and Methods: Records of Class II:1 patients who completed Herbst-MBA Tx (mean pre-Tx age 14.4 years) at Department of Orthodontics, University of Giessen, Giessen, Germany were analyzed. Tx consisted of a Herbst phase (mean 8.1 months) and a subsequent MBA phase (mean 16.1 months). Study casts from before and after Herbst-MBA Tx plus ≥24 months of retention were evaluated. Results: A total of 460 pre-Tx and 222 postretention study casts were available (total observation period: 59.2 ± 14.8 months). The overall prevalence for teeth with LGR ≥0.5 mm was 1.1% pre-Tx and 5.3% postretention. The highest prevalence of up to 5.3% (pre-Tx) and 16.4% (postretention) were seen for the lower incisors. Overall, the median magnitude of LGR was 0.0 mm pre-Tx/postretention (mean: 0.05 mm/0.08 mm). Incidence values of 4.0% (all teeth) and 10.0% to 11.4% (lower central incisors) were calculated for LGR ≥0.5 mm. Conclusions: The prevalence of LGR ≥0.5 mm increased from, on average, 1.1% to 5.3% during ≈6 years of Herbst-MBA Tx plus retention. The highest incidence was seen in lower incisors (10.0%–11.4%). However, because of the overall mean magnitude of 0.08 mm postretention, the clinical relevance can be considered as insignificant.
