In a colorless Chlorella mutant we have found only a very slight enhancement of oxygen uptake in blue light unless FMN is added to the medium. Inhibitor studies and control experiments show that a biological oxidation is involved in the increased oxygen uptake in addition to the well-known photochemical oxidations caused by free FMN. We conclude that FMN is a necessary cofactor in the blue light stimulated oxygen uptake observed in this mutant. Because of its direct role in the process FMN probably also functions as the primary light receptor. The relationship of this enhanced oxygen uptake to the blue light enhancement effects reported by others is considered briefly.

<strong><em>Naval base as one of the integral components of the SSAT is the spearhead of power in carrying out support for the tasks of the operating units both in peacetime and during war. In carrying out its duties the Navy has an Integrated Fleet Weapon System (SSAT) which is the integration of strength of the capabilities of the KRI, Aircraft, Marines and Naval base components. To find out the professional level of the soldier, it is necessary to hold a Test of Combat Naval Base Task Force in order to realize, maintain and improve the skills of both individuals and groups, which in turn will increase the establishment of Operational Command and Control, Operational Procedures and the establishment of mastery of appropriate techniques and tactics. With the implementation of the test, it is expected to know about Naval Base Combat Readiness, a condition where the base can carry out its main tasks. Combat Duty Rehearsal is an exercise carried out by KRI or base to maintain the ability and professionalism of soldiers both programmed and programmed. This study aims to determine whether the relationship of human resource readiness influences the professional abilities of the Naval Base on west coast.</em></strong>

The author begins his work with the words that the psychology that he will expound bears little resemblance to the psychology that has been the subject of study until now. In objective psychology, there should be no place for questions about subjective processes or processes of consciousness, therefore there should be no place for introspection. Self-observation is not enough even to study one's own mental life. Objective psychology has in mind to study and explain only the relationship of a living creature to the surrounding conditions that affect it in one way or another, without aiming to find out those internal or subjective experiences, which are known as conscious phenomena and which are accessible only to self-observation. All mental items should only be subject to objective registration and control.

In 2017 the number of maternal deaths was 28, consisting of 6 maternal deaths, 10 maternal deaths and 12 puerperal maternal deaths. The purpose of this study is to know the relationship of age and parity with the incidence of preeclampsia in pregnant women at dr. M. Yunus Hospital in Bengkulu year 2018. The type of research used is case control. The population in this study were all pregnant women in dr. M. Yunus Hospital in Bengkulu year 2018. The sampling technique was a case sample using total sampling, namely all pregnant women with preeclampsia and control samples using systematic random sampling technique that is sampling using multiples recorded in the hospital register of dr. M. Yunus Hospital in Bengkulu year 2018. The results of this study there is no relationship between age and the incidence of preeclampsia in pregnant women at RSUD dr. M. Yunus in 2018. With the value of p = 0.424> α = 0.05 and the value of Odds Ratio or Risk Estimate = 1.496 and there is a significant relationship between parity and the incidence of preeclampsia in pregnant women at RSUD dr. M. Yunus Bengkulu in 2018. With the value of p = 0.011 <α = 0.05 with the medium category.It is expected that the results of this study can be a program development and service improvement in reducing the prevalence of preeclampsia.

AbstractBackground:The aim of this study was to determine the serum levels of kisspeptin and ghrelin (GAH), as well as the relationship of these two peptides with each other in premature thelarche (PT) and premature adrenarche (PA) cases and to investigate the possibility of using these peptides as markers in the differentiation of puberty disorders.Methods:A PT group aged 1–8 years (n = 40), a PA group aged 1–9 years (n = 23, female/male = 20/3) and control groups consistent with each of the previous groups in terms of age and gender were created for the study. Kisspeptin and ghrelin levels were measured with ELISA methods from blood samples drawn while fasting in the morning.Results:When the PT group was compared with the controls, the plasma kisspeptin levels of the cases were significantly higher than the control group (165.47 ± 15.45 pmol/L, 96.82 ± 12.33 pmol/L, p = 0.005, respectively). Kisspeptin levels in the PA group did not show a difference with the control group (121.36 ± 17.99 pmol/L, 95.52 ± 11.54 pmol/L, p = 0.249, respectively). No significant difference could be found when GAH levels in the PT and PA groups were compared with controls. No significant correlation was found between kisspeptin and GAH levels in the PT and PA groups.Conclusions:Our results indicate that kisspeptin plays an important role in the PT, but GAH is not associated with puberty disorders.

A business-owning family and a soon-to-be-wed couple often face two mutually exclusive goals that seem impossible to reconcile. On the one hand, a couple considering marriage wants to believe that love alone will keep them together. On the other hand, statistics today say there is a good chance the relationship will not last. A prenuptial agreement provides the protection an individual or the family may want against a possible divorce, but the process by which the document is introduced and negotiated can deplete the relationship of intimacy. How can a woman from a wealthy business-owning family express and reinforce the emotional commitment and trust she has for her partner while presenting a prenuptial agreement] How can a son administer a prenuptial agreement to his fiancee without controlling the process or outcome of his spouse's financial welfare] How can a family require a prenuptial agreement without jeopardizing their future relationship with the newlyweds] In the following interview, Judy Barber, a consultant and licensed marriage and family counselor specializing in the psychology of money, outlines several recommendations for families and couples who are considering a prenuptial agreement.

In any study which involves the consideration of a network of stories, it is chiefly necessary to regard the skeleton upon which the tales in question are built up. Although it is impossible to decide upon the relationship of the various members of a cycle without some consideration of individual incidents and even turns of thought or phrase, it is constantly necessary to check and control the information thus gained by the larger matters of motive and purpose. Individual incidents and all the flesh and blood of a narrative are so easily changed that the skeleton appears stable in comparison. With due regard to the kaleidoscopic changes which are familiar to every student of this field of comparative literature, it furnishes the clue by which the labyrinth of plots must be threaded, if at all.
